Diazepam, Meprobamate, and other Psychotropic Drugs, by Bernard Desoize, Colette Leger and Gabriel Nahas Imipramine, diazepam, chlordiazepoxide, and meprobamate inhibit incorporation of 3H-thymidine in human lymphocytes in culture. For the first three drugs, 50 % inhibition occurs at a concentration of 5 x 10-5 M, and for meprobamate at a concentration of 10-3 M. Ethanol has no action up to 10-4 M. Cancerology Establishment and Characterization of 3 Human Cell Lines Derived from Secondary Brain Tumors, by Roger Le Bourny. Twelve human tumors were cultivated in vitro by the trypsinization technique and 3 cell lines were established. Each of these
technique and 3 cell lines were established. Each of these 3 lines showed individual characteristics which were maintained during passages. After inoculation into nude mice, 2 lines induced tumors which possessed the histological features of the original human tumors (melanoma and carcinoma of stomach), the other line derived from a breast carcinoma was rejected. Experimental Cancerology Exocrine Secretion of Pancreas Carcinoma Induced by Immunological Effect: Persistence of Specificity of the Ascitic Carcinomatous Pancreatic Cell, by J. Andre Thomas Pancreatic carcinomas selectively induced by immunological mechanism persistently keep their exocrine secretory specificity along the various stages of their evolution: (a) during
specificity along the various stages of their evolution: (a) during the transformation phase from adenoma to carcinoma; (b) in the evolved carcinoma; (c) in its metastasis; (d) in the ascitic carcinomatous cells formed. They are called: immuno-induced carcinoma. The carcinomatous cells of the constantly deadly ascites cease their production of secretion granules after passages by intraperitoneal graft; but this secretion reappears in the solid carcinomas they induce by subcutaneous graft and contains trypsinogen and chymotrypsinogen, even after the 92nd passage, at the 757th day. Besides, the antisera enhance the growth and the affinity for pancreas and adipose tissue of the

Different Modes of Formation of the Bauxite Breccia in Bauxite Deposits of the Western Taurides (Southern Turkey), by Necmettin Ozlu Detailed study of the bauxite breccia in different bauxite deposits in the Western Taurides (Southern Turkey) proves that these formations can be formed: 1. by the karstic dissolution and filling of the hollows or cracks in limestones; 2. by a mechanical action of the faults; and 3. by a sedimentary deposit. Geothermy Attempted Geothermometric Determination of Maxima Subsurface Water Temperatures of Main Hydro-thermic Areas of Languedoc-Roussillon and Pyrenees-Orientales, by Jacques Avias, Jacques Passavy and
of Languedoc-Roussillon and Pyrenees-Orientales, by Jacques Avias, Jacques Passavy and Jean-Louis Valat A general survey of thermomineral springs of Languedoc-Roussillon, brought out six main areas of geothermic positive anomalies. Maxima subsurface water temperatures are calculated using two geochemical indicators of subsurface temperature: SO2 content and Fournier and Truesdale Na-K-Ca formula. Results and validity limits of the two indicators are discussed.

Tectonics New Data on Late Miocene and Plio-Quaternary Tectonics of the Aegean: Mechanical and Geometric Evolution of the Hellenic Arc (Greece), by Jacques Angelier A detailed analysis of the late Miocene and Plio-Quaternary movements in the Greek islands of the Aegean Sea and along the Hellenic Arc leads to the following sequence of main tectonic events: 1, Pre-Pikermian (Late Miocene) compressional tectonics with ESE-WNW shortening; 2, NE-SW compression at the end of Miocene times (beginning of Plio-Quaternary Aegean subduction?); 3, During Pliocene and
times (beginning of Plio-Quaternary Aegean subduction?); 3, During Pliocene and Quaternary, subduction of the African plate beneath the Hellenic Arc and simultaneous inner extension and outer (i.e. marginal) compression within the Aegean plate. Nevertheless, a short event of general compression took place during the Early Quaternary. Both compression and extension were mainly transverse (i.e. radial) along the Arc. A mechanical and geometric study of all these movements leads to a model of the distribution of stresses and displacements in the Aegean area since Tortonian times, involving a slight expansion of the Hellenic Arc towards the Eastern Mediterranean (Plio-Quaternary normal faults)

Volcanology Sub Lacustrine Volcanic Formations in the South of Idjwi Island, in Kivu Lake (Western Rift of Central Africa), by Andre Pouclet Recent volcanic formations have been found in an area of the western middle-African rift known for an old activity. Their relationships with the structure is discussed. Pedology Influence of Texture on Evaporation and Drainage of Different Soils, With or Without a Plant, by Jackie Puech, Silvino Cuadrado and Marcel Hernandez The comparison of water loss by various
and Marcel Hernandez The comparison of water loss by various soils (3 to 62 % clay) shows an important difference between the texture types if the water reserves are not very often restored. In the same rainfall conditions, the soils with middle sized elements have the greatest water cession and the smallest drainage. In the case of superposition of textures, the behaviour of the system depends on the nature of the soil surface. Lastly, when there is not any limiting factor, the dry water production increases with the water cession capacity of the soil. Geology-Paleobotany New Data on the Tertiary

Mycology Study of Two Peroxidases Extracted from Root Tissues of Rubber-Tree, Both Healthy or Contaminated by Leptoporus lignosus (K.I.) Heim, by Jean-Paul Geiger and Maurice Goujon The in vivo study of peroxidases
Geiger and Maurice Goujon The in vivo study of peroxidases extractible from both healthy tissues and tissues contaminated by L. lignosus shows clearly some differences between the root tissues of Hevea brasiliensis. In particular, one can notice, within contaminated tissues, the existence of a specific peroxidase, which differs, by the molecular weight and its activity in the presence of Ca++ ions, from its isoenzymes present in healthy Tissues. The biosynthesis of this enzyme results from the fungal aggression. It is most probably a function of host cellular activity and forms perhaps a defensive reaction of the latter. Mycology Sensitiveness of

Mycology Sensitiveness of Parasitic Hymenomycetes to 5-Fluorocytosine, by René Morquer and Annick Touvet Important differences are observed between species of Hymenomycetes parasitic upon forest trees as to sensitiveness to 5-fluorocytosine. Conidiation and rhizomorphogenesis of several species are inhibited by weak doses of this antibiotic. Other species such as Fomes annosus, are much more resistant relative to their growing mycelium; nevertheless actively sporulating strains are more sensitive than paucisporous strains; their kinetic properties are disturbed by this antibiotic.

darkness O2 is not necessary for the regulation of a sporulation rhythm in L. michotii, when asparagine (6.6 x 10-3 M) is given at the replication of the cultures, though rhythm is delayed and the carotenoids "pool" is lower than control. Using 2.6 x 10-3 M of asparagine, O2 furnished at the beginning and white light after an initial 5 day-long dark period, are necessary for the first step of the photoresponse. Fatty Acids of Pollen and Styles in Oenothera missouriensis Sims, Auto-incompatible Species, by Denise Coustaut and Robert Linder Two naturally-occurring methyl esters, methyl oleate and methyl arachidonate were
Two naturally-occurring methyl esters, methyl oleate and methyl arachidonate were purified from Oenothera missouriensis Sims pollen extracts. The fatty acid composition of the total lipids was established for pollen and un-, self-, and cross-pollinated styles. Capric acid, a growth inhibitor, was only found in the pollen S- extracts. The compatible or incompatible pollination was always accompanied by a prominent decrease of the fatty acid level in the pollinated styles.

Insect Physiology Determination of a Monoaminoxydasic Activity in Locust Brain. Effect of Poisoning by two Insecticides: Chlordimeform and Dieldrin, by Daniel Gripois, Brigitte Moreteau and Francois Ramade 1079 Our investigations have shown up an MAO activity in locust brain, by the use of a radio-isotopic method, as much at larval as at adult stage. This
method, as much at larval as at adult stage. This MAO activity is in a sample of 34,3 dpmlmg of brain tissue (wet weight). Investigations have also been undertaken on effects of dieldrin and chlordimeform poisoning on this MAO activity. Even at sublethal dosages, chlordimeform causes a significant inhibition of MAO activity in vivo. This finding is in accordance with Beeman and Matsumura's in vitro. Moreover, acute poisoning by dieldrin produces more than 60 % of inhibition of MAO, 3 hours after administration of 115 gg of this insecticide by injection in the hemocelian cavity.

Experimental Embryology Investigation of Fluorigenic Amines in Chick Embryo Notochords Treated with Cholinergics, by Georges Strudel, Robert Meiniel and Gerard Gateau 1097 The investigation of 3 day old notochords by the fluorescence method of Falck and Owman showed an increase of the fluorescence after treatment of the chick embryos at 48 hrs of incubation, with nicotine sulfate or carbachol. The addition of norepinephrine or L-Dopa emphasized the formaldehyde
carbachol. The addition of norepinephrine or L-Dopa emphasized the formaldehyde induced fluorescence. The simultaneous treatment with a cholinergic agent and atropine, propranolol or reserpine decreased or suppressed the fluorescence. These results demonstrate the existence of a relationship between the treatment with a cholinergic agent and the amount of chordal biogenic amines. Ecology The Karst as an Ecosystem, by Raymond Rouch 1101 The karstic ecosystem concept is actualized from its two components, the one physical and the other biological. From a physical point of view, a karstic system forms a unit perfectly defined through its own topographic and hydrogeological characteristics. The
perfectly defined through its own topographic and hydrogeological characteristics. The faunal community which has been recently assessed in Baget (Ariege) demonstrates that the physical unity of this system balances with the ecological one. Therefore, the karstic system, should be now considered as the basic functional unity in ecology, i.e. as the karstic ecosystem. Molecular Biology Binding of Actinomycin D to a DNA Palindrome, by Jerome Lejeune 1105 A model is proposed in which the phenoxazone-ring system intercalates in a palindrome 5'-T-G-C-A-3', while the two cyclopeptides adapt themselves on the bases exposed in the wide groove of DNA.

Virology Decay of the Interferon Induced Antiviral State by PHA, by Alain Pauloin, Françoise Chany-Fournier, Lois Epstein and Charles Chany 1119 Phytohaemagglutinin (PHA M and P forms), when added to L 929 cells previously treated by murine interferon, degrades the antiviral state and restores virus sensitivity in the cells. This degradation depends on the amount of the lectin, the contact period with the cell and the presence of PHA membrane receptors. The importance of membrane configuration not only in the induction but also in the maintenance of the antiviral state is discussed.

An increase in cortisol and estradiol levels was observed three weeks before vaginal delivery of term and premature infants; in both types of delivery, onset of labor was spontaneous. In contrast, progesterone levels were only slightly decreased in these cases. Experimental Pathology Hydrothermal Shrinkage of Rat Skin. Modifications with Ageing, by Jean-Claude Allain, Suzanne Bazin, Mady Le Lous and Albert Delaunay 1131 The tension developed in Rat skin by hydrothermal shrinkage is modified with ageing of the animals: the temperature of maximum tension decreases from birth to 1
the temperature of maximum tension decreases from birth to 1 month, then very slowly increases with age. At higher temperatures than that of maximum tension a relaxation occurs very rapidly in young Rats and in not yet senescent adult skins. These modifications appeared to be related to those of the nature of the intermolecular collagen cross-links with ageing.
