Description: TECHNICAL FIELD The present invention relates to external preparations for the treatment of dermatoses. BACKGROUND ART External preparations containing an adrenocortical hormone have so far been used widely in the treatment of dermatoses, in particular intractable dermatoses such as atopic dermatitis and contact dermatitis and it is known that they have high pharmacological effects (Gekkan Yakuji (Pharmaceuticals Monthly); 26, 8, 55, 1984). Japanese Kokai Publication Sho-62-149620, for instance, discloses an external preparation containing an adrenocortical hormone as a principal active component. However, adrenocortial hormone-containing external preparations may possibly induce adverse effects at the sites of application, for example increased easy infectivity, skin thinning, vascular wall embrittlement and abnormal activation of the pilosebaceous system and, in addition, the drug substances endermically absorbed may possibly produce systemic adverse effects. Thus, the closest attention should be paid to their doses. Therefore, for hydrocortisone acetate, for instance, which is a typical adrenocortical hormone, the Japanese Pharmacopoeia prescribes an upper limit use concentration of about 1% by weight and, for dexamethasone and prednisolone, an upper limit concentration of about 0.1 to 0.5% by weight. On the other hand, external preparations with reduced adverse effects are also available, for example external preparations containing a nonsteroidal antiinflammatory agent and/or an antihistaminic agent. However, as compared with adrenocortical hormone-containing ones, they are much less effective against such intractable dermatoses as mentioned above (Shinyaku to Chiryo (New Remedies and Therapy); 25, 298, 41, 1984). As mentioned above, adrenocortical hormones have high pharmacological effects but are disadvantageous in that they have strong side effects. Therefore, it is earnestly desired that preparations with which clinical effects comparable to those attained with the conventional preparations can be produced at lower adrenocortical hormone concentrations be developed. In the state of the art, even if higher clinical effects are required, it is impossible to increase their contents to levels exceeding those currently employed, when their side effects are taken into consideration. For solving these problems, Japanese Kokai Publication Sho-61-40210 discloses a preparation for treating dermatoses and skin protection which comprises vitamin E and Japanese Kokai Publication Sho-53-136521 discloses a preparation for the treatment of vegetating dermatoses which contains α - tocopherol. However, these are insufficiently effective in intractable dermatoses possibly due to the low concentration of vitamin E or α -tocopherol in the preparations. Japanese Kokai Publication Hei-06-179619 discloses an external preparation for the treatment of dermatoses which contains vitamin E and a transdermal absorption enhancer. However, when it is administered continuedly for achieving satisfactory therapeutic effects, the transdermal absorption enhancer may possibly produce skin irritating effects. Furthermore, Japanese Kokai Publication Hei-06-247852 discloses an external preparation for the treatment of dermatoses which contains 1 to 30% by weight of vitamin E and 1 to 30% by weight of squalene. It is known that this vitamin E- and squalene-containing external preparation for treating dermatoses can be widely applied to dermatoses without producing such adverse effects as encountered with the steroid-containing preparations mentioned above. However, for producing higher clinical effects, preparations showing still stronger effects are desired. US-4,216,201 discloses water-in-oil emulsions of high water content (60 to 80% by weight) for cosmetic uses. The cosmetic emulsions disclosed are reported to effectively transport water to the inner layers of the skin, while minimizing water loss by evaporation, and enabling up to about 10% by weight of other cosmetic substances (such as coloring agents) to be carried in the emulsions. Squalene and/or squalane is used as a lipid "carrier" of "micro-droplets" of the emulsions. In some cases, squalane and vitamin E are present, such as in the composition of claim 2, consisting of squalane (4%), alpha tocopherol acetate (0.1%), squalene (4%), and other components, including 71.3% water (plus vitamins A and D). US-4,454,159 discloses preparations for the treatment of itching, dry, roughened, sensitive or irritated skin conditions such as sunburn, poison ivy, diaper rash, pruritus ani, and flaky or keratinaceous dry skin problems. The lipid/lipoid compositions diclosed are designed to simulate, as closely as possible, the composition and/or activity of skin lipids/lipoids, and are said to work by maintaining a proper oil-water balance of the skin. In the composition of example 1 (in claim 5), 1.5% of squalane is present, 0.21% of tocopherol, 61.9% of water, 4% glycerol trioleate, 1.0% collagen hydrolysate etc. US-5,378,461 discloses compositions for the treatment of skin disorders and damage, specifically in the treatment of hypertrophic and keloid scar tissue, acute phototoxicity, hyperpigmented lesions, skin discloration, keratosis and skin hardening. The compositions disclosed in US-5,378,461 are based on ubiquinones of the coenzyme Q family, which are known to play a role in reducing aging processes induced by free radicals. The compositions disclosed use squalane as an "oil-based carrier". The compositions comprise several active ingredients, including vitamins A and E, a ubiquinone (coenzymes Q 4 to Q 15 ), and squalane. EP-313303 describes a number of photoprotection (sunscreen) compositions containing vitamin E, specifically in the form of tocopherol sorbate, plus an anti-inflammatory agent. Most preferably, the compositions contain cinnamates, benzophenone and/or dibenzoylmethane derivatives as (further) sunscreen agents, and the anti-inflammatory agent is nonsteroidal in nature The compositions described are useful for protecting the skin from the harmful effects of ultraviolet radiation, such as sunburn and sun-induced premature aging. EP-313303 outlines in general terms a pharmaceutical/cosmetic composition based on a micro-emulsion carrier system comprising: squalane (9 to 15%), tocopherol sorbate (2 to 10%), an anti-inflammatory agent (0.2 to 5%), silicone oil (25 to 40%), other components and water. JP-04-346917 describes a medicated cream effective for treating allergies containing Glycyrrhizae and Scutellariae plant extracts. The cream is an emulsion obtained from purified water containing preservatives, which is mixed with a lipid phase based on squalane (10%), Vaseline (25%) and liquid paraffin (15%). The lipid phase also contains di-alphatocopherol acetate (0.05%), plus the plant extract dipotassium glycyrrhizinate (0.05%), Scutellariae extract (1.0%) etc. SUMMARY OF THE INVENTION In a first aspect of the present invention, it is an object thereof to provide an external preparation for the treatment of dermatoses which has an efficacy at least equivalent to that of external preparations containing an adrenocortical hormone as an active ingredient and which produces only reduced adverse effects.

BEST MODES FOR CARRYING OUT THE INVENTION The following examples are further illustrative of the present invention but are by no means limitative of the scope thereof. Examples 1 to 24 and Comparative Examples 1 to 10 Ointments were prepared by supplying Plastibase (Taisho Pharmaceutical), vitamin E acetate (Wako Pure Chemical Industries), vitamin E nicotinate (Wako Pure Chemical Industries), vitamin E succinate (Sigma Chemical), squalane (Wako Pure Chemical Industries), isopropyl myristate (Nacalai Tesque), dexamethasone (Wako Pure Chemical Industries) and prednisolone (Wako Pure Chemical Industries), in amounts specified below in Tables 1 to 3, to a mortar, and kneading the mortar contents until the components other than Plastibase were dissolved in the latter. In Examples 13, 14, 16 and 17, Plastibase was not used, hence the preparations prepared were liniments. The thus-obtained ointments and liniments were subjected to tests 1 to 5 described below (except for the ointment obtained in Example 18, which was not tested). In each test run, five rats were used and the results were expressed in terms of mean value. [Test Example 1] Effect on DNCB-induced primary skin irritation (nonallergic dermal inflammatory reaction) After the frank of 7-week-old Wistar rats was clipped of hairs, 20 µ 1 of 2% 2,4-dinitrochlorobenzene (DNCB, Wako Pure Chemical Industries)-acetone was applied to the exposed skin area and let dry thoroughly to induce nonallergic dermatitis. Then, 0.1 g samples from the ointments or liniments obtained in the foregoing examples and comparative examples were respectively deposited on a 1 cm (radius) disk of polyethylene sheet and applied against the site of DNCB-induced dermatitis. Twenty-four hours after induction of dermatitis, the intensity of local erythema was evaluated using a chromameter (CR-200, Minolta). In a control run, the ointment base (Plastibase) alone was applied in lieu of the test preparation and erythema intensity measurement was performed in the same manner. From the results of measurement of the erythema intensity (A) at the site of application of the control and the erythema intensity (B) at the site of application of the test preparation, the erythema inhibition percentage was calculated as follows: Erythema inhibition (%) = [(A - B)/A] x 100 The results thus obtained are shown in Tables 1 to 3. [Test Example 2] Effect on PCA reaction (type I allergic reaction) (1) Preparation of rat anti-DNP-As serum Rat anti-DNP-As serum was prepared by the method of Tada and Okumura (Journal of Immunology; 106, 1002, 1971). Thus, an Ascaris suum (swine roundworm) extract was prepared by the method of Strejan and Campbell (Journal of Immunology; 98, 893, 1967), and then treated with 2,4-dinitrofenyl sulfate (DNP) by the method of Eisen et al. (Journal of American Chemical Society; 75, 4583, 1953) to give DNP-bound Ascaris suum (DNP-As). The above DNP-As (1 mg) was dissolved in 1 ml of physiological saline containing 1 x 1010 killed cells of Bordetella pertussis as suspended therein and the resulting suspension was administered to female rats weighing about 200 mg by subcutaneous injection into the dorsum of each foot. After 5 days, 0.5 mg of DNP-As was dissolved in 0.5 ml of physiological saline and the solution was injected into the right and left muscles of the back. Eight days after the first injection, blood was collected from the abdominal aorta and serum was separated. Thus, rat anti-DNP-As serum was obtained. (2) PCA reaction The above-mentioned rat anti-DNP-As serum was diluted with physiological saline and the dilution was administered to male rats weighing about 120 to 200 g by intradermal injection into the back at a dose of 0.05 ml. After 45 hours, 0.1 g of each of the test preparations, the ointments and liniments obtained in the above-mentioned examples and comparative examples, was applied to the site of injection of anti-DNP-As serum in the same manner as in Test Example 1. After 3 further hours, 0.5% Evans' blue solution in physiological saline containing the DNP-As antigen was administered by intravenous injection at a dose of 2.5 ml/kg to thereby induce the PCA reaction. Thirty minutes later, the animals were sacrificed and the dye that had leaked out in the area of skin reaction was extracted by the method of Harada et al. (Journal of Pharmaceutics Pharmacology; 23, 218, 1971), namely by excising the reaction area of the skin, mincing the same and immersing the same in a mixed solution composed of 0.3% aqueous sodium sulfate solution and acetone (3:7, v/v) for not less than 48 hours. Then, the dye extracted was assayed by absorbance at 620 nm. In a control run, the ointment base (Plastibase) alone was applied in lieu of the test preparation, then the same procedure was followed, and the dye extracted was assayed by absorbance. From the results of determination of the amount (C) of the dye extracted from the site of application of the control and of the amount (D) of the dye extracted from the site of application of each test preparation, the dye-leakage inhibition percentage was calculated as follows: Dye-leakage inhibition (%) = [(C - D)/C] x 100 The results thus obtained are shown in Tables 1 to 3. [Test Example 3] Effect on delayed contact dermal hypersensitivity (type IV allergy) reaction in rats After the frank of 5-week-old Wistar rats was clipped of hairs, 20 p 1 of 20% 2,4-dinitrochlorobenzene (DNCB, Wako Pure Chemical Industries)-acetone was applied to the exposed skin area and allowed to sit for 2 weeks for sensitization. After sensitization, the dorsal skin was clipped of hairs and 20 µ1 of 0.5% DNCB-acetone was applied to induce contact dermatitis. Then, 0.1 g samples from the ointments or liniments obtained in the examples and comparative examples were respectively applied to the site of DNCB-induced dermatitis in the same manner as in Test Example 1. Twenty-four hours after induction of dermatitis, the intensity of local erythema was evaluated using a chromameter (CR-200, Minolta). In a control run, the ointment base (Plastibase) alone was applied in lieu of the test preparation and erythema intensity measurement was performed in the same manner. From the results of measurement of the erythema intensity (E) at the site of application of the control and the erythema intensity (F) at the site of application of the test preparation, the erythema inhibition percentage was calculated as follows: Erythema inhibition (%) = [(E - F)/E] x 100 The results thus obtained are shown in Tables 1 to 3. [Test Example 4] Systemic effect evaluated in terms of body weight change All the rats of the test groups and control group as used in Test Example 3 were weighed before and after testing and the possible systemic side effect was evaluated in terms of body weight changes. The results obtained are shown in Tables 1 to 3. [Test Example 5] Organoleptic evaluation of feel upon use The ointments or liniments obtained in Examples 1 to 17 and 19 to 24 were each applied to the skin of five human subjects and evaluated for the feel upon application thereof according to the criteria mentioned below, and the mean value was calculated. The results are shown in Tables 1 and 2. Evaluation criteria: 0: Significant stickiness and flow, no good feel. 1: Stickiness and flow noted. 2: No stickiness or flow, very good feel. In Tables 1 to 3, in the column "Species" below "Vitamin E", A stands for vitamin E acetate, B for vitamin E nicotinate, and C for vitamin E succinate. In the same tables, IPM stands for isopropyl myristate, Dex for dexamethasone, and Pre for prednisolone. The ointments having low vitamin E and low squalane contents as obtained in Examples 1, 2 and 18 were further tested in the following manner. [Test Example 6] Effect of repeated administration on delayed contact dermal hypersensitivity (type IV allergy) reaction in rats After the frank of 5-week-old Wistar rats was clipped of hairs, 20 µ1 of 20% 2,4-dinitrochlorobenzene (DNCB, Wako Pure Chemical Industries)-acetone was applied to the exposed skin area and allowed to sit for 2 weeks for sensitization. After sensitization, the back was clipped of hairs and 0.1 g samples from the ointments obtained in Examples 1, 2 and 18 were respectively applied once daily for 3 days prior to inducing contact dermatitis in the same manner as in Test Example 1. Three days after commencement of ointment application, 20 µ1 of 0.5% DNCB-acetone was applied to induce contact dermatitis. Then, 0.1 g samples from ointments obtained in Examples 1, 2 and 18 were respectively applied to the site of DNCB-induced dermatitis in the same manner as in Test Example 1. Twenty-four hours after induction of dermatitis, the intensity of local erythema was evaluated using a chromameter (CR-200, Minolta). In a control run, the ointment base (Plastibase) alone was applied in lieu of the test preparation and erythema intensity measurement was performed in the same manner. From the results of measurement of the erythema intensity (G) at the site of application of the control and the erythema intensity (H) at the site of application of the test preparation, the erythema inhibition percentage was calculated as follows: Erythema inhibition (%) = [(G - H)/G] x 100 The results thus obtained are shown in Table 4. Composition (weight %) Test Example 6 (%) Plastibase Vitamin E Squalane Species Content Example 1 96 A 2 2 44 2 90 A 5 5 56 18 97.5 A 0.5 2 38 Furthermore, the ointments obtained in Examples 3 to 5, 8, 11, 12 and 19 to 24 and Comparative Examples 9 and 10 were tested in the following manner. In each test run, five rats were used and the results were shown in terms of mean value. [Test Example 7] Effect on type III allergy model (1) Preparation of rabbit anti-ovalbumin serum Rabbit anti-ovalbumin serum was prepared by the method of Eda et al. (Folia Pharmacologica Japonica; 66, 237, 1970). Thus, ovalbumin (Sigma) was dissolved in physiological saline to a concentration of 2 mg/ml. An equivolume mixture (emulsion) of this solution and Freund's complete adjuvant (Difco) was used as an antigen preparation and 0.5 ml thereof was injected into the right and left gluteal muscles of each male rabbit (New Zealand white strain) four times at one-week intervals. Seven days after the last injection blood was collected from the carotid artery and serum was separated and recovered. Thus, rabbit anti-ovalbumin serum was obtained. (2) Four-hour heterologous passive cutaneous anaphylaxis reaction in rats The above rabbit anti-ovalbumin serum was 4-fold diluted with physiological saline and 0.05 ml of the dilution was intradermally injected into the back of each Wistar strain male rat weighing about 200 g. Then, 0.1 g of each of the ointments obtained in the above-mentioned examples and comparative examples was applied to the rat skin at the site of application of the antiserum in the same manner as in Test Example 1. Then, 4 hours after antiserum injection, 0.5% Evans' blue solution in physiological saline containing 2 mg/ml of ovalbumin was intravenously administered at a dose of 2.5 ml/kg to thereby induce the PCA reaction. The dye that had leaked out at the site of the thus-induced intracutaneous reaction was extracted and assayed by the method of Harada et al. (Journal of Pharmaceutics Pharmacology; 23, 218, 1971). Thus, 30 minutes after Evans' blue administration, the animals were sacrificed. The skin excised from the reaction area was minced and immersed in a mixed solution of 0.3% aqueous solution of sodium sulfate and acetone (3:7, v/v) for not less than 48 hours for effecting extraction of the dye that had leaked out. The dye thus extracted was then assayed by absorbance at 620 nm. In a control run, the ointment base (Plastibase) alone was applied in lieu of the test preparation. Thereafter, the same procedure was followed and the dye extracted was assayed by absorbance. From the results of determination of the amount (I) of the dye extracted from the site of application of the control and of the amount (J) of the dye extracted from the site of application of each test preparation, the dye-leakage inhibition percentage was calculated as follows: Dye-leakage inhibition (%) = [(I - J)/I] x 100 The results thus obtained are shown in Tables 5 to 6. [Test Example 8] Effect on delayed dermal hypersensitivity reaction (tuberculin-induced type IV allergy reaction) in rats The method of Kuriyama et al. (Folia Pharmacologica Japonica; 94, 113, 1989) was followed. BCG (Bacillus Calmette-Guerin) (2.5 mg; Nihon BCG) was suspended in 1 ml of physiological saline. The suspension was heat-treated at 121 °C for 5 minutes and 0.2 ml thereof was injected into the peritoneal cavity of each 9-week-old Wistar rat. Seven days after BCG injection, 200 µg of purified tuberculin (Nihon BCG) was dissolved in 1 ml of physiological saline and two 0.1-ml portions were respectively intradermally injected into two sites on the clipped back of the above rat. Physiological saline, which was free of purified tuberculin, alone was also intradermally injected at another site on the clipped back in the same manner. Then, 0.1 g of each of the test preparations (ointments obtained in the above-mentioned examples and comparative examples) applied in the same manner as in Test Example 1 such that the ointment contacted the rat skin at one of the sites of injection of purified tuberculin. As a control, the ointment base (Plastibase) alone was applied, in lieu of the test preparation, to the rat skin at the other tuberculin injection site in the same manner. Twenty-four hours after said tuberculin injection, the diameter of the resulting erythema was measured and, from the results of measurement of the erythema diameter (K) at the control application site and of the erythema diameter (L) at the test preparation application site, the erythema inhibition percentage was calculated as follows: Erythema inhibition (%) = [(K - L)/K] x 100 The results obtained are shown in Tables 5 and 6. [Test Example 9] Effect on solar dermatitis (ultraviolet erythema) The test preparations were examined for effect on ultraviolet-induced erythema by the method of Tsuji et al. (Oyo Yakuri (Pharmacometrics); 23, 567, 1982). Thus, the back of guinea pigs weighing 250 to 300 g was clipped of hairs. The skin of the back was then covered with a light-shielding cloth having three round holes with a diameter of 7 mm and ultraviolet irradiation was carried out from a distance of 20 cm for 30 seconds using a 1,000 watt ultraviolet lamp (Toshiba). Each (0.1 g) of the ointments obtained in the above-mentioned examples and comparative examples was applied as the test preparation to the site of ultraviolet-induced erythema 3 hours prior to irradiation and immediately after irradiation. Five hours after induction of dermatitis, the intensity of local erythema was evaluated using a chromameter (CR-200, Minolta). As a control, the ointment base (Plastibase) alone was applied in the same manner in lieu of the test preparation and thereafter the erythema intensity was measured following the same procedure. From the results of measurement of the erythema intensity (M) at the site of control application site and the erythema intensity (N) at the site of test preparation application, the erythema inhibition percentage was calculated as follows: Erythema inhibition (%) = [(M - N)/M] x 100 The results obtained are shown in Tables 5 and 6. [Test Example 10] Effect on wound healing The ointments were evaluated for effect on wound healing by the method of Sakyo et al. (Oyo Yakuri; 43, 121, 1992). The back of 5-week-old Wistar rats was shaved of hairs and using a surgical knife, a 30 mm-long incision was made along the median line under ether anesthesia. Immediately after incision, the wound was sutured in 3 equispaced positions. Then; 0.2 g samples from the ointments obtained in the above examples and comparative examples were respectively spread on gauze (3-ply), 2.5 cm x 5 cm, and applied to the wounded area and an occulusive dressing using an elastic adhesive bandage was applied for fixation. The ointment-coated gauze was exchanged once/daily. The suture was removed 3 days after commencement of the experiment. On day 6, the skin covering the whole wounded area was excised from each rat and 1 cm-wide skin strips parallel to the wound line (2 strips/rat) were prepared. Both ends of each strip were fixed to an NRM-3002D-L rheometer (Fudoh) and the tension force (g/cm) required for cutting the strip at the wound site was measured. The mean measured value for two strips was taken as the tension value for one sample. As a control, the ointment base (Plastibase) alone was applied in the same manner in lieu of the test preparation and thereafter tension measurements were carried out following the same procedure. The results obtained are shown in Tables 5 and 6. When tested in the above manner, the external preparation for the treatment of dermatoses according to the first aspect of the present invention showed effects equivalent to those of external preparations containing an absorption enhancer or adrenocortical hormone and, unlike the adrenocortical hormone-containing external preparations, did not show any body weight loss due to side effects.

In Test Examples 1 to 4, 7 and 11, each ointment was evaluated using 5 rats and the results were expressed in terms of mean value. In Test Example 9, 5 guinea pigs were used for each ointment and the results were expressed in terms of mean value. The results obtained are shown in Tables 10 and 11. [Test Example 11] Effect on delayed dermal hypersensitivity reaction (tuberculin reaction) in rats The method of Kuriyama et al. (Folia Pharmacologica Japonica; 94, 113, 1989) was used. Thus, 2.5 mg of BCG (Bacillus Calmette-Geurin; Nihon BCG) was suspended in 1 ml of physiological saline, the suspension was heat-treated at 121°C for 5 minutes and a 0.2-ml portion thereof was injected into the peritoneal cavity of each 9-week-old Wistar rat. Seven days after BCG injection, 0.1 ml of a solution prepared by dissolving 200 µg of purified tuberculin (Nihon BCG) in 1 ml of physiological saline was intradermally injected into two sites on the clipped back the above rat. Physiological saline, which was free of purified tuberculin, alone was intradermally injected at another site on the clipped back in the same manner. Then, 0.1 g of each of the test preparations obtained in the above-mentioned examples and comparative examples was applied in the same manner as in Test Example 1 so that the ointment came into contact with one of the purified tuberculin injection sites on the rat skin. As a control, the ointment base (Plastibase) alone was applied in the same manner to the other tuberculin injection site on the rat skin. Twenty-four hours after tuberculin injection, the color tone of the resulting erythema was measured using a chromameter. From the results of measurement of the color difference value (K) for the erythema at the control application site and of the color difference value (L) for the erythema at the test preparation application site, the erythema inhibition percentage was calculated as follows: Erythema inhibition (%) = [(K - L)/K] x 100 The results obtained are shown in Tables 10 and 11.

[Test Example 12] Effect on type II allergic reaction (1) Preparation of rabbit anti-rat serum Rabbit anti-rat serum was prepared by the method of Eda et al. (Folia Pharmacologica Japonica; 66, 237, 1970). Thus, serum was collected from male Wistar rats weighing 150 to 200 g. An equivolume mixture (emulsion) of this rat serum and Freund's complete adjuvant (Difco) was used as an antigen preparation and 0.5 ml thereof was injected into the right and left gluteal muscles of each male rabbit (New Zealand white strain) four times at one-week intervals. Seven days after the last injection, blood was collected from the carotid artery and serum was separated and recovered. Thus, rabbit anti-rat serum was obtained. (2) Effect on anti-rat serum-induced intradermal reaction The ointments were examined for effect on anti-rat serum-induced intracutaneous reaction by the method of Kuriyama et al. (Folia Pharmacologica Japonica; 95, 83, 1990). The above rabbit anti-rat serum was 4-fold diluted with physiological saline and 0.1 ml of the dilution was intradermally injected into the back of each male Wistar rat weighing about 200 g. Then, 0.1 g of each of the ointments obtaioned in the above-mentioned examples and comparative examples was applied to the rat skin at the site of application of the anti-rat serum in the same manner as in Test Example 1. Further, 2 hours thereafter, 0.5% Evans' blue solution in physiological saline was intravenously administered at a dose of 2.5 ml/kg. The dye that had leaked out at the site of the thus-induced reaction was extracted and assayed by the method of Harada et al. (Journal of Pharmaceutics Pharmacology; 23, 218, 1971). Thus, 30 minutes after Evans' blue administration, the animals were sacrificed. The skin containing the dye that had leaked out was excised from the reaction area, minced and immersed in a mixed solution composed of 0.3% aqueous solution of sodium sulfate and acetone (3:7, v/v) for at least 48 hours for effecting extraction of the dye that had leaked out. The dye thus extracted was then assayed by absorbance at 620 nm. As a control, the ointment base (Plastibase) alone was applied in lieu of the test preparation. Thereafter, the same procedure was followed and the dye extracted was assayed by absorbance. From the results of determination of the amount (O) of the dye extracted from the site of application of the control and of the amount (P) of the dye extracted from the site of application of each test preparation, the dye-leakage inhibition percentage was calculated as follows: Dye-leakage inhibition (%) = [(O - P)/O] x 100 The results thus obtained are shown in Tables 28 and 29. [Test Example 13] Effect on solar dermatitis (ultraviolet erythema) The ointments were examined for effect on ultraviolet-induced erythema by the method of Tsuji et al. (Oyo Yakuri ; 23, 567, 1982). Thus, the back of guinea pigs weighing 250 to 300 g was clipped of hairs. The skin of the back was covered with a light-shielding cloth having three round holes with a diameter of 7 mm and ultraviolet irradiation was carried out from a distance of 20 cm for 30 seconds using a 1,000 watt ultraviolet lamp (Toshiba). Immediately thereafter, 0.1 g of each of the ointments obtained in the above-mentioned examples and comparative examples was applied as the test preparation to the site of ultraviolet-induced erythema in the same manner as in Test Example 1. After 24 hours, the skin reactions were scored according to the criteria shown below and the sum of scores for the three sites was used for evaluating each test preparation. As a control, the ointment base (Plastibase) alone was applied in the same manner in lieu of the test preparation and thereafter the skin reactions were evaluated by the same procedure. Evaluation criteria 0 : No change 1 : Slight erythema 2 : Medium erythema 3 : Marked erythema 4 : Marked erythema and edema From the erythema score (M) for the control and the erythema score (N) for the test preparation application sites, the ultraviolet-induced erythema healing percentage was calculated as follows: UV-induced erythema healing (%) = [(M - N)/M] x 100 The results thus obtained are shown in Table 28 and 29. [Test Example 14] Effect on wound healing The ointments were evaluated for effect on wound healing by the method of Sakyo et al. (Oyo Yakuri; 43, 121, 1992). The back of 5-week-old Wistar rats was shaved of hairs and using a surgical knife, a 30 mm-long incision was made along the median line under ether anesthesia. Immediately after incision, the wound was sutured in 3 equispaced positions. Then, 0.2 g samples from the ointments obtained in the above examples and comparative examples were respectively spread on gauze (3-ply), 2.5 cm x 5 cm, and applied against the wounded area and an occulusive dressing using a stretchable bandage was applied for fixation. The ointment-coated gauze was exchanged once/daily. The suture was removed 3 days after commencement of the experiment. On day 8, the skin covering the whole wounded area was excised from each rat and 1 cm-wide skin strips parallel to the wound line (2 strips/rat) were prepared. Both ends of each strip were fixed to an NRM-3002D-L rheometer (FUDOH) and the tension force (g/cm) required for cutting the strip at the wound site was measured. The mean measured value for two strips was taken as the tension value for one sample. As a control, the ointment base (Plastibase) alone was applied in the same manner in lieu of the test preparation and thereafter tension measurements were carried out following the same procedure. From the tensile strength (Q) of the healed wound in the control group and the tensile strength (R) of the healed wound for the test preparation application sites, the wound healing percentage was calculated as follows: Wound healing (%) = [(Q - R)/Q] x 100 The results are shown in Table 28 and 29.

Furthermore, when the external preparations according to the fifth aspect of the present invention were used, any significant body weight loss due to side effects was observed, unlike the case of the adrenocortical hormone-containing external preparations. It was thus shown that the present invention, in its fifth aspect, provides highly safe external preparations for the treatment of dermatoses, which are widely effective against dermatoses. Reference Example 293 [Synthesis of acrylic adhesive] A separable flask equipped with a stirrer and a condenser was charged with 301.1 weight parts of 2-ethylhexyl methacrylate, 34.9 weight parts of 2-ethylhexyl acrylate, 48.3 weight parts of dodecyl methacrylate, 0.0384 weight part of 1,6-hexaneglycol dimethacrylate and 256.0 weight parts of ethyl acetate, and the flask contents were heated to 70°C with stirring and nitrogen substitution. A solution of 2.0 weight parts of lauroyl peroxide in 100.0 weight parts of cyclohexane was divided into 10 aliquots. One aliquot was added to the separable flask to thereby initiate the polymerization. Starting at 5 hours after initiation of the polymerization, the remaining 9 aliquots were added one by one at 1-hour intervals. After completion of the addition, the reaction was further carried out for 19 hours. For viscosity adjustment, five 27 weight part portions of ethyl acetate were added portion by portion at 5-hour intervals after initiation of the reaction. After completion of the reaction, the reaction mixture was cooled and ethyl acetate was further added to give an adhesive solution with a solid content of 50% by weight. [Production of tape-form preparation] The above adhesive solution (100 weight parts), 20 weight parts of vitamin E acetate (Wako Pure Chemical Industries), 15 weight parts of squalene (Sigma) and 15 weight parts of squalane (Wako Pure Chemical Industries) were fed to a dissolver-type high-speed mixer and homogeneously blended to give a mixed solution. The thus-obtained mixed solution was applied to a silicone-treated polyethylene terephthalate film (38 µm thick) and then dried at 60°C for 30 minutes to give a 80-µm-thick adhesive layer. The above adhesive layer was then transferred onto the ethylene-vinyl acetate copolymer layer of a 34 µm thick polyethylene terephthalate/ethylene-vinyl acetate copolymer laminate film, to give a tape-form preparation. Reference Example 294 [Synthesis of acrylic adhesive] The procedure of Example 293 was followed to give an adhesive solution with a solid content of 50% by weight. [Production of tape-form preparation] A tape-form preparation was obtained in the same manner as in Example 293, using 127 weight parts of the above adhesive solution, 10 weight parts of vitamin E acetate (Wako Pure Chemical Industries), 1.5 weight parts of squalene (Sigma), 15 weight parts of squalane (Wako Pure Chemical Industries) and 10 weight parts of isopropyl myristate. INDUSTRIAL APPLICABILITY Being constituted as detailedly described hereinabove, the external preparation for the treatment of dermatoses according to the first aspect of the present invention shows high therapeutic effects against dermatoses with reduced side effects as compared with external preparations whose main component is an adrenocortical hormone. Therefore, external preparations useful in the treatment of various dermatoses can be obtained. The external preparation for the treatment of dermatoses according to the second aspect of the present invention contains vitamin E and squalane in addition to an adrenocortical hormone and therefore shows a higher therapeutic effect against intractable dermatoses as compared with the case where the adrenocortical hormone is used alone. The addition of vitamin E and squalane within respective specific concentration ranges is more effective and makes it possible to obtain high therapeutic effects on dermatoses with low adrenocortical hormone concentrations. Therefore, external preparations for the treatment of dermatoses which can be provided show high curative effects with reduction in side effects due to adrenocortical hormones. Furthermore, when said preparation further contains a specific transdermal absorption enhancer, the active ingredients can readily be adsorbed into the skin and high therapeutic effects can be produced against intractable dermatoses. The external preparation for the treatment of dermatoses according to the third aspect of the present invention, which contains a nonsteroidal antiinflammatory agent, vitamin E and squalane and/or squalene, produces high therapeutic effects on intractable dermatoses with reduced side effects as compared with external preparations containing an adrenocortical hormone as a main active ingredient. Therefore, external preparations useful in various dermatoses can be obtained. In particular, when the nonsteroidal antiinflammatory agent, vitamin E and squalane and/or squalene are used within respective specific concentration ranges, external preparations useful in various dermatoses can be obtained more efficiently. Furthermore, when said preparation further contains a specific transdermal absorption enhancer, the active ingredients can readily be adsorbed into the skin and high therapeutic effects can be produced even against intractable dermatoses, with reduced side effects as compared with external preparations containing an adrenocortical hormone as a main active ingredient. Thus, external preparations useful in the treatment of various dermatoses can be obtained. The external preparation for the treatment of dermatoses according to the fourth aspect of the present invention, which contains an antihistaminic agent, vitamin E and squalane and/or squalene, produces high therapeutic effects even on intractable dermatoses with reduced side effects as compared with external preparations containing an adrenocortical hormone as a main active ingredient. Therefore, external preparations useful in various dermatoses can be obtained. In particular, when the antihistaminic agent, vitamin E and squalane and/or squalene are used within respective specific concentration ranges, external preparations useful in various dermatoses can be obtained more efficiently. Furthermore, when said preparation further contains a specific transdermal absorption enhancer, the active ingredients can readily be adsorbed into the skin and high therapeutic effects can be produced even against intractable dermatoses, with reduced side effects as compared with external preparations containing an adrenocortical hormone as a main active ingredient. Thus, external preparations useful in the treatment of various dermatoses can be obtained.
