The epidermal cell proliferation in lichen planus
Authors: Ebner H , Gebhart W , Lassmann H , Jurecka W.
Published: July 2023

The proliferative activity of epidermal structures was determined in 6 patients suffering from lichen planus (i.p.). By using the in vitro 3H-thymidine labelling technique, semithin Epon sections of lesional and perilesional uninvolved skin were compared autoradiographically with normal controls. The following results were obtained. The labelling index of epidermal cells was significantly increased within the i.p. papules. The mean values ranged from 41% in acanthotic i.p. to 23% in atrophic i.p. whereas in adjacent unaffected skin (15% and 11% respectively) as well as in normal controls (6%) a lower 3H-index was observed. As regards damage to basal cells within i.p. lesions, a factor--the relation between the number of basal cells in involved and uninvolved skin in reference to the epidermal length--was calculated in order to correct the autoradiographic results in involved skin. The differences between i.p. papules, adjacent skin and controls remained statistically significant even after correction. The intradermal eccrine ducts revealed a significantly increased labelling index in i.p. lesions as compared with perilesional and normal skin. In this respect no difference could be observed between the acanthotic and the atrophic variant of i.p. These findings indicate that replacement of damaged basal cells in i.p. is achieved by an increase in actively dividing keratinocytes in both epidermis and skin appendages within the lesion.
Genetic markers in psoriasis. Correlations to age at onset, continuity of symptoms and the risk of developing the disease
Authors: Beckman L , Bergdahl K , Cedergren B , Lidén S.
Published: July 2023

In a study on genetic markers (22 HLA antigens, 6 blood group types, 3 serum groups and 3 red cell enzymes) in psoriatic patients the following statistically significant differences were found between patients and controls: 1) The HLA factors B13 and Bw17, the Lewis blood group Le(a-b-) and the blood group factor A were overrepresented among the patients. A decrease in the frequencies of the HLA factors B7 and B8 was noted, confirming several similar findings by other investigators. 2) In the Ss (MNSs), C3 and haptoglobin (Hp) systems the psoriatic patients showed a decreased frequency of heterozygotes. 3) Among patients with continuous symptoms the blood group factor A and the blood group Fy (a+b-) were overrepresented. 4) Patients with late onset of psoriasis showed an increase in the blood group (Fy(a+bb-) and a decrease in the haptoglobin type 2-2. Relative risk figures have been calculated for different phenotypes. Certain genetic combinations were found to be grossly overrepresented among the patients. The mechanisms behind the associations appear to differ. In three systems (Ss, C3 and Hp) the deviations in psoriatic patients suggest the presence of heterozygote advantage.
Hydrocortisone (cortisol) concentration and penetration gradient
Authors: Kranz G , Schaefer H , Zesch A.
Published: July 2023

Hydrocortisone (Cortisol) was incorporated into four different ointments at four concentrations (0.1% 0.3%, 1%, and 3%) and the amounts of the drug penetrating from these preparations into the different layers of excised skin were investigated. The effect of removing the horny layer on the penetration was also determined. Below a level of 1% ointments with intact horny layer and 0.3% with removed layer, a change in the ointment concentration alters the tissue concentration in the ratio 1:1. Above this level doubling of the concentration in the ointments causes an increase of tissue concentrations of only 20-50%. The removal of the horny layer increases the dermal concentrations 100 fold at each ointment concentration. Furthermore, a vasoconstriction test was performed with the different ointments. An increase in the concentrations above the 1% level failed to increase the effect on the vascular system of the skin. The in vitro and in vivo results are discussed with respect to the consequences on affected skin and the therapeutic efficacy of steroid preparations of different concentrations.

Authors: Bretteville-Jensen G , Mossing N , Albrechtsen R.
Published: July 2023

123 patients suffering from axillary hyperhidrosis have been operated on as outpatients under local anaesthesia, with radical ablation of sweat glands. All except 7 patients were satisfied with the result. There were few complications. A group of patients and controls were extensively studied including quantitative sweat testing and axillary biopsis. Apart from increased axillary sweating during the test, no differences could be found. The basic etiology of the condition is still unknown.

Drug phototoxicity in mice
Authors: Ljunggren B , Möller H
Published: July 2023

A series of agents with alleged photosensitizing properties has been studied in mice by a quantitative in vivo method for acute drug phototoxicity. The method, originally developed for phenothiazine studies, was found suitable for several drug groups with varying mechanism of action, such as tetracyclines, protoporphyrin and psoralens. In the sulfa group only sulfanilamide was active, although weakly. Phototoxicity in vivo, hitherto not demonstrated, was observed with griseofulvin, nalidixic acid, imperatorin, kynurenic acid and amiodarone.
Plasma levels of 8-methoxypsoralen and phototoxicity studies during PUVA treatment of psoriasis with meladinin tablets
Authors: Thune P
Published: July 2023

A new tablet formulation of 8-methoxypsoralen was used in PUVA treatment for psoriasis. The 8-Mop plasma level showed a maximum at about 1 hour after ingestion (mean values: 1/2 hr, 284 microgram/1; 1 hr, 275 microgram/1; 1 1/2 hr, 198 microgram/1; 2 hrs, 129 microgram/1). Phototoxicity tests showed the optimal time for exposure to be about 1 hour after peroral intake of 8-MOP.
Chlamydia trachomatis urethritis in men attending a venereal disease clinic: a culture and therapeutic study
Authors: Ripa KT , Mårdh PA , Thelin I
Published: July 2023

Urethral specimens from 459 male patients attending a venereal disease clinic were studied for presence of Chlamydia trachomatis and Neisseria gonorrhoeae. Of the 459 patients, 362 had symptoms suggestive of urethritis. In these 362, gonorrhoea was diagnosed in 78 (22%), while 88 (24%) harboured C. trachomatis; 15 harboured both organisms. Of those patients from whom C. trachomatis was isolated, 17% had no subjective symptoms of urethritis; the same percentage of symptomless carriers of gonococci was found. Watery discharge occurred more frequently in patients with chlamydial urethritis than in patients with gonorrhoea, while in the latter condition purulent discharge was more often found. Treatment with doxycycline for 9 days rendered 28 of 29 chlamydia-positive patients culture negative at control.
Local absorption of zinc from wounds treated with various zinc-compounds
Authors: Hallmans G
Published: July 2023

It is shown that in the rat, zinc is absorbed from excisional wounds into serum, from various locally applied zinc oxide preparations as well as from zinc peroxide and zinc sulphate. The most pronounced absorption of zinc to serum was recorded from wounds treated with zinc peroxide. Microscopically the cellular inflammatory response observed in wounds treated with a gauze sponge impregnated with a zinc sulphate solution was weaker than that found with the other treatment methods used.
Axillary hyperhidrosis: local treatment with aluminum chloride hexahydrate 25% in absolute ethanol
Authors: Brandrup F , Larsen PO
Published: July 2023

Eleven women (group I) with axillary hyperhidrosis were treated ad modum Shelley & Hurley with local application of aluminium chloride hexahydrate 25% in absolute ethanol and plastic foil occlusion during two successive nights once a week. The patients were observed for 24 weeks. Another 12 women (group II) were treated for up to 12 weeks with aluminium chloride hexahydrate 25% in absolute ethanol but without using plastic foil occlusion. We have attempted to determine the effect of the treatment by sweat measurements, leaving the left axilla untreated during the initial 1--2 weeks as a control. An immediate reduction in sweat production of the treated axilla was found in both groups. The reduction increased during the first weeks and was maintained thereafter. The degree of sweat reduction was the same during standardized work and during rest (group II). At the final controls all patients in group I had discontinued the occlusion and had individualized the treatment, most of them using local application 1--2 times weekly. Two patients in group I had to stop the treatment because of unbearable itching. The other patients found the treatment completely satisfactory. All patients had experienced itching and smarting when starting the treatment. Often these discomforts were temporary but they seem to require active support by close medical control during the initital period of treatment. In contrast to previous investigations, effective treatment was achieved both with and without occlusion.

Authors: Freeman MJ , Taylor JS , Levin HS , Dyment PG , Bergfeld WF
Published: July 2023

Histiocytic medullary reticulosis (HMR) is a rare, progressive, fatal reticuleondothelial proliferative disorder. It was diagnosed in a 10-year-old boy who had pityriasis lichenoides et varioliformis acuta of Mucha-Haberman which was controlled by dapsone for 2 years. One month after cessation of dapsone therapy, cutaneous tumors associated with fever, lymphadenopathy, and hepatosplenomegaly developed. Tissue biopsy specimens of skin, liver, spleen, lymph nodes, and a bone marrow aspirate demonstrated histiocytic erythrophagocytosis and atypical histiocytosis compatible with HMR. A rapidly progressing, fatal course followed despite intensive chemotherapy.

An in vitro study of IgE production in severe atopic dermatitis
Authors: Hovmark A.
Published: July 2023

Peripheral blood lymphocytes from 4 patients with severe atopic dermatitis and with high serum IgE levels produced measurable amounts of IgE in vitro in repeated tests. These patients had increased numbers of IgE-bearing peripheral blood lymphocytes on at least one test occasion. No measurable IgE production in vitro was found in 6 other patients with atopic dermatitis and in 3 healthy controls. Inhibition of the IgE production was observed following treatment with PHA, Con A, PWM, mixed lymphocyte culture and radiation. LPS and histamine induced neither definite stimulation nor inhibition of IgE production. Supernatants from Con A stimulated cells were used in tests for suppressor factors. The hypothesis that depressed suppressor function of the T cells might be responsible for the tendency to increased IgE production in atopic dermatitis is discussed.

Authors: Bhonsle RB , Pindborg JJ , Gupta PC , Murti PR , Mehta FS.
Published: July 2023

In a house-to-house survey in South India, comprising 10,000 villagers, the age-adjusted incidence rate per 1,000 person-years for oral lichen planus was found to be 2.1 for males and 2.5 for females, based upon a 10-year follow-up study. The highest incidence was in the age group 55-64 for males and 45-54 for females. The age-adjusted relative risk was higher for the 'chewing habits' group (6.2) than for the 'smoking habit' group (2.2). The combined effect of the two habits appeared to be multiplicative; the age-adjusted relative risk for the mixed habit group being 13.7.
Fibrinoid necrosis and downward motion of colloid bodies in lichen planus (apoptosis)
Authors: Sümegi I.
Published: July 2023

Fibrinoid necrosis which in previous investigations was demonstrated in the epithelial cells of the skin and of the liver in certain disorders, may also appear in the colloid bodies in lichen planus. Trichrome stainings were positive for fibrinoid, staining reactions with haematoxylin variants indicated the presence of keratin and precursors, and investigations in Wood's light permitted conclusions concerning the appearance of mixed proteins, of which keratofibrinoid seems to be the most important. Circulatory disturbances are emphasized as having an important role. The colloid bodies are extruded from the epidermis, according to the observations of Kerr et al., following the rules of apoptosis.

Dermatological features of five 47,XYY males are presented. Port-wine stains were observed in 2 cases. As the incidence of port-wine stains among the general population is believed to be 0.5%, this result would seem to indicate that the association of 47,XYY males with port-wine stains is more than a coincidence, though the survey of previous studied failed to reveal any 47,XYY cases with port-wine stains.
Circulating immune complexes in lupus erythematosus, scleroderma and dermatomyositis
Authors: Sølling J , Sølling K , Jacobsen KU.
Published: July 2023

Circulating immune complexes (CIC) were measured by three different methods in serum from 17 patients with systemic lupus erythematosus (SLE), 3 patients with "hydralazine-induced" SLE-like syndromes, 14 patients with discoid lupus (DLE), 8 patients with systemic sclerosis and 5 patients with dermatomyositis. Immune complexes were detected in 13 of the 17 patients with SLE. All patients with lupus nephritis and typical exanthema had circulating immune complexes. The concentration of immune complexes was inversely correlated to serum complements C4 and C3. All 3 patients with "hydralazine-induced" SLE-like syndromes had circulating immune complexes that disappeared after withdrawal of the drug. Immune complexes were detected in 3 of the 14 patients with DLE; all 3 patients with CIC had wide-spread DLE. In systemic sclerosis, CIC were detected in only 1 of the 8 patients. Four of the 5 patients with dermatomyositis demonstrated CIC in serum. No complement consumption was detected in dermatomyositis and the immune complexes may have been secondary to tissue destruction.
Immunofluorescent and electron-microscope findings in the uninvolved skin of patients with systemic lupus erythematosus
Authors: Halevy S , Ben-Bassat M , Joshua H , Hazaz B , Feuerman EJ.
Published: July 2023

Specimens of uninvolved skin of 20 patients with systemic lupus erythematosus (SLE) were studied using a direct immunofluorescent technique (IF) and the electron microscope (EM). EM examination revealed deposits of electron-dense material below the basal membrane, among collagen fibers in the dermis and in the walls of dermal blood vessels. The direct IF technique revealed granular "band" deposition of immunoglobulins and complement at the dermo-epidermal junction as well as granular deposition in the walls of blood vessels. There was close correlation between the IF and EM findings. It was concluded that the EM is of particular value in precisely delineating the location and ultrastructural pattern of skin deposits. The IF technique is not limited in relation to the size of area which can be studied and makes it possible to identify the specific immune fractions present. It is suggested that these two methods are mutually complementary in providing information concerning the deposition of immunoglobulins taking place in the uninvolved skin of SLE patients.
Inhibition of hyperhidrosis by topical application of a local anesthetic composition
Authors: Juhlin L , Evers H , Broberg F.
Published: July 2023

An eutectic mixture of 5% lidocaine and 5% prilocaine applied locally to the skin inhibited epinephrine-induced sweating in healthy subjects. It also inhibited palmar and axillary hyperhidrosis from 1 to 6 hours after application to 15 of 17 patients tested. A placebo lotion was without effect. When used daily for 3--4 weeks, only 25% of the patients were very pleased with the treatment. The reason for the decrease of efficacy is uncertain.
Changes in muscarinic acetylcholine receptor binding in skin slices of cholinergic urticaria.
Authors: Haustein U F , Schliebs R , Schaller J
Published: July 2023

Muscarinic acetylcholine receptors were studied in slices of unaffected skin and in lymphocyte membranes from 3 patients with cholinergic urticaria and 5 healthy subjects using receptor autoradiography and the radioligand [3H]quinuclidinyl benzilate binding technique. Autoradiography revealed that muscarinic acetylcholine receptors were located in regions with sweat glands. The distribution of receptors did not differ qualitatively between patients and controls. However, the maximum number of muscarinic acetylcholine receptors was reduced in skin from patients with cholinergic urticaria, by 44% as compared with the controls, whereas the binding affinity was not affected. Muscarinic cholinergic binding in lymphocyte membrane fractions obtained from patients with cholinergic urticaria did not differ statistically from that of healthy control persons.

We have studied the immunohistochemical localization of desmosomal and cytoskeletal proteins in the epidermis of healthy individuals and patients with Hailey-Hailey's disease. It was found that the localization of desmosomal proteins (desmoplakin, desmoglein) and keratin filaments in the involved epidermis of patients with Hailey-Hailey's disease was almost same as that in the normal epidermis of healthy individuals. In contrast, the localization of actin filaments in the involved epidermis of patients with Hailey-Hailey's disease differed from that in the normal epidermis of healthy individuals.

Twelve non-atopic women with nickel allergy and allergic contact dermatitis (pompholyx type) were compared with matched controls without any known allergy. Intercellular fluid was obtained by the suction blister technique, and sufficient material for analysis was available from 10 women from each group. The median nickel concentration was 16 nmol/l in the patient group and 39 nmol/l in the controls (p less than 0.02). Calculated dietary intake of nickel during the week before examination was similar in the two groups, but the fluid intake was larger in the control group. Urine was collected in the morning before examination by 11 women in each group; the nickel concentrations showed no difference between the two groups. These observations suggest that cellular uptake of nickel in sensitized patients may be sufficient to influence the kinetics of nickel in the body.

Interleukin-1 release from peripheral blood monocytes and soluble interleukin-2 and CD8 receptors in serum from patients with atopic dermatitis.
Authors: Thestrup-Pedersen K , Larsen C S , Kristensen M , Zachariae C
Published: July 2023

In 31 adult patients with atopic dermatitis, the capacity to secrete interleukin-1 (IL-1) from peripheral blood mononuclear cells and from purified monocytes was investigated following stimulation with lipopolysaccharide. We also measured soluble interleukin-2 receptor levels (sIL-2R) and CD-8 receptor in serum from some of the patients in order to estimate the degree of lymphocyte stimulation in vivo. We observed that purified monocytes from patients with atopic dermatitis released more IL-1 than unseparated blood mononuclear cells did and also had significantly greater IL-1 activity than non-atopic donors. Addition of histamine in concentrations of 10(-7) to 10(-4) M did not suppress, but rather augmented the IL-1 activity release. An increased monocyte-IL-1 release could lead to increased T lymphocyte activity. We observed that 60% of the patients had increased sIL-2R concentrations in serum. There was no correlation between serum IgE and sIL-2R. Our observations indicate that monocytes in atopic dermatitis patients release increased quantities of IL-1, supporting an augmented T lymphocyte activation in the patients.
Effects of cyclosporin A on cultured human epidermal keratinocytes. Growth and 5-bromo-2'-deoxyuridine incorporation.

Published: July 2023

We have studied the in vitro effect of CsA at various doses (0.5, 1, 5, 10 micrograms/ml) on the growth and 5-bromo-2'-deoxyuridine (BrdU) incorporation by cultured normal human epidermal keratinocytes (EK). CsA was found to reduce the growth of EK at all doses used after 24, 48 and 72 h in culture, but the difference with appropriate controls became statistically significant for the dose of 10 micrograms/ml after a 48- and 72-h culture. On the other hand, CsA-treated EK comprised a reduced fraction of BrdU + (S-phase) cells, the difference being statistically significant for the dose of 10 micrograms/ml at 24, 48 and 72 h. Ultrastructural examination of CsA-treated EK, despite the presence of cytoplasmic vacuoles also observed in control EK did not show signs of severe cytoplasmic or nuclear damage. These results confirm the antiproliferative effect of CsA on cultured EK and suggest that at the concentration used, CsA acts through a cytostatic rather than a cytotoxic mechanism, most likely by blocking EK in an early phase (G0/G1) of the cell cycle.

Proliferation and differentiation of cultured epidermal cells from patients with X-linked ichthyosis and ichthyosis vulgaris.
Authors: Jensen P K , Herrmann F H , Hadlich J , Bolund L
Published: July 2023

The growth, differentiation, and regeneration of epidermal cultures from patients with X-linked and autosomal dominant ichthyosis and normal individuals were compared. Cell proliferation was studied by combining the technique of fluorescence-activated cell sorting with [3H]thymidine labelling and autoradiography. As in normal epidermal cultures, a marked heterogeneity in the labelling intensity of S-phase cells was observed in the ichthyotic cultures with totally unlabelled as well as very strongly labelled cells. However, in contrast to normal cultures, by far the largest proportion of S-phase cells in the ichthyotic cultures were very strongly labelled with a corresponding, severe reduction in the proportion of un- and weakly labelled cells. The increased labelling intensity of S-phase cells was observed in primary as well as in regenerating cultures, although it was most pronounced in the latter case. There was no difference between cultures from the two types of ichthyotic skin. The morphologic differentiation in the cultures was assessed by measurement of mean diameter of sorted S-phase cells and by quantitation of cornified envelop formation. Both parameters were reduced in the ichthyotic cultures, compared with normal ones. Taken together, these findings are indicative of a hyperproliferative state in the ichthyotic cultures.

Published: July 2023

Evaluation of the placement of the coolnet distance on direct evaporative cooling is needed in order to reduce the wilting percentage and improve seed production of potatoes. The aim of the study was to obtain the appropriate coolnet distance for the growth and development of aeroponic potato seedlings in evaporative cooling and root zone cooling applications in the tropical lowlands. The factors tested were: 1) Evaporative cooling (JEvap) distance: JEvap1 (25 cm from the top zone of the plant), JEvap2 (50 cm from the top zone), and Jevap3 (60 cm), and 2) Varieties (V): V1 (MZ), V2 (Granola K), V3 (Granola L). The design used was completely randomized design with 2 replications. Growth data and results were analyzed by the F test and continued with Duncan's Multiple Range Test (DMRT) at 5% level. The results showed that the direct evaporative cooling method and the coolnet spacing of 50-60 cm which were integrated with root zone cooling created an air temperature at the top of the plant 26-28 °C, reduced the percentage of burnt wilting, and increased the number of tubers by an average of 31.4 to 41.7 tubers/plant. Keywords: Aeroponic, cooling system, growth environment, hidroponic, limited control.

This type of research is qualitative research with a descriptive analysis approach. The main instrument in this study was the researcher himself, assisted by supporting instruments such as writing instruments and cameras. This type of data uses primary data and secondary data. Data collection techniques were carried out by observation, interviews, and documentation studies. The data analysis technique is done by collecting data, describing the data and concluding the data. The results showed that the planning made by the teacher, namely lesson plans, was relevant to the design of K13 because the topic of learning in K13 Class X IPA 2 SMA N 4 Sungai Full Semester two (even) was a dance tradition. The suitability of subject topics in K13 is the existence of KD and KD indicators following the expected learning of K13 objectives. The teacher uses the strategy of delivering material, assessment, and learning using the question and answer method. With this method, the authors found that students were less interested in participating in learning. As for the third meeting, the teacher must be able to use a demonstration strategy by giving an example to students on how to properly move traditional dances. The technique used by the teacher must also be more creative to attract the attention of students. The process of supporting the learning of arts and culture at SMA Negeri 4 Sungai Penuh is also not sufficient. The lack of facilities and infrastructure provided by schools also results in learning that is not carried out properly.

The data in this study there are primary data and secondary data. Interviews, literature studies, and observations are activities carried out in data collection techniques. The steps to analyze the data are data reduction, data presentation and conclusion. Based on what was obtained, the research showed that the process of learning arts and culture through limited face-to-face sessions in class XI IPS SMAS Salafiyah Babussalam was quite good. Even though there are limitations in learning media, the teacher teaches music learning material to follow the flow, where the teacher provides music material using a gradual way to adjust the level of a student's capacity to receive material even though the learning time is relatively short. However, there are obstacles that make it difficult to achieve the final results or learning objectives properly due to the lack of learning time, as well as the unavailability of musical instruments to support the practical learning process, so the teacher only uses the lecture method during material delivery. However, learning outcomes are not too bad because students' interest in learning and students' desire to explore the material is very high even though the learning is monotonous, when viewed from the results obtained based on daily test activities which are quite good.

One of the impacts of The Programme for International Student Assessment (PISA) on Indonesia is the change in the curriculum in the Indonesian education system. The curriculum that is implemented today, emphasizes students on 21st century skills and the change from teacher center to student center. The reality in the field, learning Physics in class  shows that teachers still approach directly and involve students less in the learning process so that students are less motivated in learning which makes learning outcomes low. The purpose of this study was to see the effect of the problem based learning model with concept map on physics students achievement. This type of research is quasi experimental design. The instrument used in this study is a test instrument. The results showed that the average score of students in the experimental class of 63.88 was higher than the sample class of 59.21. Accompanied by quiz data, it also showed that the average score of the experimental class was higher than the control class at each meeting. The results of the hypothesis test obtained by the zcalculate >z table are 7.16>1.96 so that it can be said to reject Ho accept H1. Thus, the application of the PBL model accompanied by concept maps can be used and applied to students so that their learning outcomes increase
