esculenta pituitary glands were continuously superfused for 7 hrs at 28°C with amphibian culture medium. a-MSH release was measured by use of a sensitive double antibody radio-immunoassay system. a-MSH secretion was inhibited by low temperatures. A large increase in a-MSH release was observed when Thyrotropin Releasing Hormone (TRH) at doses ranging from 10-1 to 10-7 molar was added to the superfusion medium. Since large amounts of TRH are to be found in the hypothalamus of amphibians but have no effect over pituitary TSH secretion, the action of TRH over a-MSH release may have a physiological significance. Neurochemistry Identification of Catecholamines and of Serotonin in Chick Embryo Notochords, by Georges Strudel, Max Recasens and Paul Mandel 967 The neurotransmitter amines, norepinephrine, dopamine and serotonin have been isolated from Chick notochords. Cholinergic agents produce important modifications in the amount of these amines and of one of their metabolites. The results demonstrate the presence, at a very early stage of development between the second and the third day of incubation, of biogenic amines and cholinergic receptors. Biology Ponderal Evolution of Eggs in Leucophaea Maderae Fabr. (Insecte, Dictyoptera), by Jacques Darquenne 971 Eggs in Leucophaea maderae are present in an ootheca which remains in the broodsack until hatching of the larvae. During incubation, the water content of the eggs increases from 36 to 77 %, the dry weight remaining constant. Water is possibly provided by the mother. Genetics The Phenotypic Expression of the scute Locus in Drosophila melanogaster, by Michele Thomas-Orillard 975 The number of the long thoracic chaetae of heterozygous females born from crosses between a scute stock and various wild strains can be less than eight. Penetrance and dominance vary according to the wild strain considered. The phenomenon is probably connected with an anomaly of the development. Pharmacology High Affinity Binding of 5-Hydroxytryptamine to Bovine Brain Membranes; Interrelations with Lysergic Acid Diethylamide, by Gilles Fillion, Marie-Paule Fillion, Jean-Claude Rousselle, Dominique Beaudoin, Michel Gouny and Joseph Jacob 979 5-Hydroxytryptamine binds to crude brain membrane preparations with two different affinities (KD = 1 to 2 x 10-8 M for the highest, 1 to 2

Pharmacology High Affinity Binding of 5-Hydroxytryptamine to Bovine Brain Membranes; Interrelations with Lysergic Acid Diethylamide, by Gilles Fillion, Marie-Paule Fillion, Jean-Claude Rousselle, Dominique Beaudoin, Michel Gouny and Joseph Jacob 979 5-Hydroxytryptamine binds to crude brain membrane preparations with two different affinities (KD = 1 to 2 x 10-8 M for the highest, 1 to 2 x 10-9 M for the lowest). LSD also binds with two affinities (KD = 3 to 4 x 10-9 M and KD = 2 to 3 x 10-8 M). Subcellular distribution of these sites shows that binding involves the two binding affinities in microsomal membranes but solely the high affinity binding sites are present in purified synaptosomal membranes. High affinity sites for 5-HT and for LSD are different as no direct competitive inhibition is observed in that case. On microsomal membranes, direct relationship occurs between low affinity binding for 5-HT and high affinity binding for LSD. Toxicology Experimental Study in Rats of the Reduction of the Carbon Monoxide Content of Blood After Cigarette Smoke Exposure, by Means of Oxygen Inhalation Under Atmospheric Pressure, by Leon Le Bouffant, Camille Izard, Henriette Daniel, Jean-Pierre Henin, Jean-Charles Martin and Pierre Payen When animals are exposed to cigarette smoke, the concentration of carbon monoxide in blood is rapidly increased, so that intensive inhalation tests cannot be carried out. A simple apparatus is described to expose Rats alternatively to cigarette smoke and to oxygen in order to reduce the concentration of carbon monoxide in the blood.

A simple apparatus is described to expose Rats alternatively to cigarette smoke and to oxygen in order to reduce the concentration of carbon monoxide in the blood. This method makes it possible to increase the daily administration of smoke considerably; nevertheless, under such conditions, lung tumors were not observed. Physiological Toxicology Inhibition of Lymphoblastic Transformation by 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 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 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 carcinomatous ascitic strains they induced. They, sometimes produce nodular hepatic carcinomas. Medicine Proof of the Efficacy of Synoviorthesis by 169-Erbium in Rheumatoid Arthritis of the Fingers Obtained by a Double-Blind Study, by Florian Delbarre, Charles Menkes and Alice Le Go A double-blind study (201 metacarpo and interphalangeal joints) on the effectiveness of the synoviorthesis shows the significant value of the 169-Erbium, compared with intra-articular placebo or corticotherapy. The treatment gives an improvement in 58 % of the cases (p < 0,01) (stade I 80,7 %), by destruction of the rheumatoid pannus, begins after 3 months and develops for one year

Preliminary Results of a Survey on the Metamorphism in the Autochthon of the Western Taurus (Area of Karacahisar, Turkey), by Jean-François Dumont and Alain Desprairies The sedimentary series of the Paleozoic and of the lower Trias show a slight metamorphism. We have attempted to state precisely its intensity using more especially the crystalline measures of the illites-micas. 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 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.

Geochemistry of Waters Geochemical Origin of Lithium in the Subterranean Waters of the Paris Region, by Alain Fruchart and Maurice Pinta The study of certain characteristic parameters drawn up from subterranean water and petrographic investigations determined precisely the origin of lithium in the subterranean waters offine sheets. It was shown that the origin of lithium was tied, essentially, to the clayed fraction of the reservoir rock. Geochemistry Identification of a Polymer from Hydrolyzed Aluminium Solutions, by Jean-Yves Bottero, Jean-Maurice Cases, Patrice Rubini and Francois Fiessinger The NMR study of an hydrolyzed aluminium chloride solution, where the [OH]2[Al3+] ratio in the preparation, is greater than one, shows the presence of a [Al2O4AlIV(OH)24(H2O)2]" polymer. The concentration of this aluminium species is 28 % of the aluminium total when r = 2.5. It increases upon ageing while the turbidity decreases. 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

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 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) and a small correlative accentuation of the curvature of the Arc. 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.

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 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 of the Djiring Highlands, by Henri Fontaine and Colette Vozenin-Serra Discovery of continental paleogene strata in the Djiring highlands (Vietnam), with pollens of lowlands plants. Study of neogene clays with fossil woods belonging also to a low altitude flora. The data tend to specify the time of the upwards move of the plateau and the following basaltic volcanism.

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 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 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.
