primordia. Toxic Effects on Quail of 2,4,5-Trichlorophenoxyacetic Acid, by Robert Didier 847 The treatment of Quails by 2,4,5-trichlorophenoxyacetic acid has no effects on fertility and egg weight, but a significant decrease in egg production and important lesions of the liver are observed. Genetics New Aspects of the Intersubgeneric Crossing Chrysocarabus (s. str.) auronitens Fabr. x Chrysocarabus (Chrysotribax) hispanus Fabr. (Coleopt. Carab.), by Clement Puissegur 851 In the limits of the intersubgeneric crossing Chrysocarabus (s. str.) auronitens Fabr. x Chrysocarabus (Chrysotribax) hispanus Fabr., the results change with the subspecies of Cc. auronitens positive only up to F1, but very little productive with a. festivus Dej. and a. auronitens Fabr., negative with a. subfestivus Oberth. and a. cupreonitens Chevr. Toxicology Milk Aflatoxin and Relay Toxicity, by Raymond Ferrando, Andre Parodi, Nicole Henry, Jean Delort-Laval and Amadou Lamine N Diaye 855 Diet including 20 p. 100 of lyophilised milk produced by Goats who consume peanut meals containing 1,530, 79 and 54 ng/kg aflatoxins with 1,136, 64 and 54 μg/kg aflatoxin B1, is given to ducklings during 23 days. There is no influence of this diet on growth, feed efficiency and liver or kidney histology. In contrast, direct consumption of Peanut meal, with the highest level of aflatoxins, produces 18 p. 100 mortality and characteristic injuries of aflatoxicosis. Cellular Pharmacology Mode of Action of New Antimitotic Thiopyrimidine Derivatives at the Cell Level, by Roger Bassleer, Freddy De Parmentier, Jean-Claude Jamoulle and Charles-Leon Lapiere 859 New thiopyrimidine derivatives have been synthesized. Among them, several inhibit the multiplication of Chick embryo cells cultivated in vitro: they provoke strong nucleolar alterations, prevent the cells from entering into mitosis and can give rise to cell polyploidization as to DNA. Immunochemistry Lymphoid Cells of the Intestinal Mucosa with Double Specificity Kappa and Lambda in the Normal Man, by Lucien Hartmann and Panayotis Liacopoulos 863 The presence of lymphoid cells possessing both kappa and lambda specificities has been observed in the intestinal mucosa of normal subjects. The variability in the number of such cells in different sections of the same sample and in different subjects seems to be a characteristic

The variability in the number of such cells in different sections of the same sample and in different subjects seems to be a characteristic of this cell population and may reflect the high activity of the immune system in the small intestine. Cancerology Sensibility to X-Ray Irradiation of Human Lymphoblastoid Cells Cultured in Media Supplemented by Nickel Sulphate, by Jacques Bensimon and Jean-Noël Rimbert 867 Human leukaemic cells of the established line REH, cultured in media supplemented by nickel sulphate have been irradiated by X-Rays. The nickel sulphate and the X-rays have toxic effects that appear as independent or interdependent effects according to the X-ray doses, the nickel sulphate concentration and the nickel sulphate action endurance. Locally they are contemporaneous with the lower dolomitic deposits of the Adoudonian. This facies boundary within the Infracambrian of the Anti-Atlas is heterochronous. Copper mineralizations are located on this facies boundary. The Geochronological Datation of "gneiss de Brest" (West Brittany) Called into Question Again, by Bruno Cabanis, Jean Michot and Sarah Deutsch Recent geological and geochronological researches question the "gneiss de Brest" age obtained by Adams. Petrography Melt Inclusions from Cordierites of Rhyodacitic Lavas of Tuscany (S. Vincenzo) and of North Tunisia (Ain ed Deflaia), by Robert Clocchiatti and Nicole Metrich Melt inclusions trapped in cordierite phenocrysts from rhyodacitic lavas from Tuscany and Tunisia have many similar characters:

Vincenzo) and of North Tunisia (Ain ed Deflaia), by Robert Clocchiatti and Nicole Metrich Melt inclusions trapped in cordierite phenocrysts from rhyodacitic lavas from Tuscany and Tunisia have many similar characters: size, shape, distribution of cavities, chemical composition of filling. The glass trapped in both crystal types have the same chemical evolution as the composition of bulk rock and residual glass. Cordierites were crystallized at high temperature (950°C) and low pressure (I to 2 kbar) under the same physical and chemical conditions. Stratigraphy Discovery of Bashkirian in the Upper Paleozoic of the Southern Slope of Western Hindu Kush, in Afghanistan, by Jean Boulin, Emmanuel Bouyx, Maurice Lys and Daniel Vachard Bashkirian microfaunas of Bamyan Mountains permit us to date a part of infrapermian formations in this area to the carboniferous period, and to verify, at least in this period, the generality of the upper paleozoic transgression in the Western Hindu Kush. Tectonics Metamorphism and Magmatism in the Armorican Massif during the Variscan Orogenesis: a Plate Tectonic Interpretation, by Louis Chauris Subduction zone, paired metamorphic belts (high and low pressures) and granitoidic belts (leucogranites and granodiorites, biotite granites) in the hercynian armorican massif.

First hydrodynamic arguments on the sorting of the arenites substantiate it. Secondly it is shown that irregular distribution of recent sediments cannot be a model. Finally geological data corroborate the bathymetric interpretation. A New Way of Studying Layer Thickness Distribution in Subperiodic Stratigraphic Series, by André Rivière and Alain Desprairies Necessary limitation of total thickness of stratigraphic series implies, aside from intervening occurrences, a frequency inversely proportional to each strata thickness (use of logarithmic scale for thickness). Natural thickness distributions are generally too asymmetrical to be considered as gaussian-logarithmic. An the contrary, parts of these distributions corresponding respectively to X = log x < X (mode) and to X > X (mode) are generally very near to inferior and superior parts of two different gaussian-logarithmic distributions of which means are equal to mode of the natural distribution, and standard deviation curiously proportional to infra, and on the other side, supra parts of the natural distribution (frequency proportional to square root of variance). Geological interpretation of these facts and of end truncatures. Plant Physiology Oil and Protein Content in Sunflower Achene (Helianthus annuus L.).

Variations During Grain Filling, with Nitrogen Supply and Achene Location in Inflorescence, by Pierre Lencelot, Jean Decau and Jackie Puech During grain filling, protein and oil percents in dry matter grow simultaneously. But differences appear according to nitrogen supply and achene location: particularly, oil contents are higher (and protein content lower) in outer grains than in the inner ones. It is shown that these oil content differences come from physiological age disparities while it is suggested that other variations originated in grain filling possibilities and metabolic phenomena. Plant Histophysiology Tissue Culture of Vicia faba minor, by Marie-Noël Gueziec, Jean-Paul Parvais and Rose Galzy A number of tissue strains were established from stems of Vicia faba minor. The growth is maintained on a well-defined nutrient medium. However, the addition of coconut milk to this medium promotes a more rapid growth. After one year, most of the mitoses observed in the callus were abnormal. Palynology New Interpretation of the "order" of Celastrales with the Help of Palynology, by Danielle Lobreau-Callén Through the study of pollen characteristics, the Celastrales order appears heterogeneous but made up of two groups which may be related either to Rosidae (group I) or to Dilleniidae (group II).

Mycology Comparison Between Extracellular Enzymes Synthesized by the Three Mycelial Types of the Thallus of Leptoporus lignosus (Kl.) Heim, by Jean-Paul Geiger and Maurice Goujon According to the synthesis of extracellular enzymes, the different elements of the thallus of Leptoporus lignosus show a specialization similar to those of Corticium rolfsii. In both fungi the intramycelial mycelium is the only one which produces extracellular enzymes; but Leptoporus lignosus excretes laccases when Corticium rolfsii excretes hydrolases, which explains their peculiar pathogenicity. Morphogenesis of the Mycobiont of the Pertusaria pertusa (L.) Tuck. In Pure in vitro Cultures, by Richard Lallemant The ascospores of the Pertusaria pertusa grow numerous germinative tubes; the hyphae originated from them produce a great number of conidiospores which germinate, causing the formation of a small mycelial heap. A primordium of a multiaxial cladonia grows up above this mycelium, and will later be replaced by a central cavity around which a central multilobed vesicle will develop, the wall of which will be differentiated into three superposed zones. Phytopathology On a Toxin Produced by Phoma lingam Tode, a Fungus Parasite of Rapeseed; Isolation and Properties, by Jean-François Bousquet, Jean-Pierre Ferezou, Michel Devys and Michel Barbier The isolation and properties of a toxin C18H24N2O7S2 produced by the fungus Phoma lingam Tode, a parasite of Cruciferae, are reported. This compound inhibits the growth of Brassica rapae roots

Entomology Sexual Receptivity in Female and Insemination Power in Male of Culex pipiens autogenicus (Diptera, Culicidae). Rigorous Monogamy Case and Possible Polygamy Case, by Thanh Xuan Nguyen and Jean-Louis Cabes Females of Culex pipiens autogenicus generally have two refractory periods: post-emergence refractory period (during the first 48 hrs. after emergence) and post-insemination refractory period. Males of Culex pipiens autogenicus can inseminate 2 to 3 females. After the 4th insemination, he can no longer completely fulfill his reproductive role. Therefore, the female can be inseminated by another male. Zoology X-Ray Microanalysis of Integument and Digestive Gland of Crangon crangon (Linne) (Crustacea Decapoda) Quantitative Variations of Calcium, Phosphorus, Sulfur and Magnesium Related to Intermolt Cycle, by Colette Chassard-Bouchaud 933 Electron probe microanalysis is a very suitable method for qualitative and quantitative analysis of calcium, phosphorus, sulfur and magnesium occurring within integument and digestive gland; variations related to intermolt cycle can be compared.

The two types of cells exhibit an extensive protein synthesis and the secretory process seems to be apocrine. The significance of these two types of cell is discussed. Cytophysiology Localization of Cholinesterase Activity in a Marine Invertebrate (Nereis pelagica L., Annelida polychaeta). Photonic and Electron Microscopic Studies, by Nicole Dhainaut-Courtois 941 High specific and nonspecific cholinesterase activities have been demonstrated in the whole nervous system of Nereis. These might reveal the existence of a cholinergic nervous system whose control would be exerted in different sites (central nervous centers, muscular junctions...). Neuroanatomy Radioautographic Analysis of Primary Optic Projections in a Diurnal Bird of Prey (Buteo buteo L.), by Jean-Pierre Raffin, Jacques Repérant and Domenico Miceli 945 Radioautographic analysis of the optic system of a Common Buzzard (Buteo buteo L.) shows hypothalamic (Meier's areas 1, 2 and 3), thalamic (nuclei lateralis anterior, geniculatus lateralis ventralis, dorsolateralis anterior), pretectal (nuclei geniculatus lateralis pretectalis-or Kuhlenbeck's geniculatus lateralis dorsalis-superficialis synencephali, griseus tectalis and area pretectalis), tegmental (nucleus ectomamillaris) and tectal visual projections. A general survey of Common Buzzard optic structures suggests a certain preponderance of tectofugal system on thalamofugal system. Centrifugal visual system is reduced.

Experimental Embryology Action of DDT on the Gonadic Germ Population in Quail Embryos from Five Successive Generations, by Danielle David 949 The gonadic germ deficit induced by DDT in Quail embryos issued from eggs only treated at the first generation, partially decreases at the second generation and completely at the third. When the DDT treatment is repeated for each generation, the reduced effect slightly increases. Physiology Unfertilizability of in vitro Matured Hamster Oocytes, by Jacqueline Mandelbaum and Michelle Plachot 953 The comparative study of fertilization, with the same sperm sample, of in vitro matured oocytes and freshly ovulated ones, shows a new aspect of mammalian oocyte maturation. While 80% of freshly ovulated oocytes are fertilized, in vitro matured eggs are not fertilizable. They present the ability to be penetrated by spermatozoa 4 to 6 hrs. only after HCG injection. This is therefore not an tubal influence but depends on an oocyte specific factor which appears during the end of intrafollicular maturation. Invertebrate Physiology Thermoperiodic Control of Diapause Induction in Pieris brassicae L. (Insecta, Lepidoptera), by Bernard Dumortier and Jeannine Brunelius 957 When exposed their whole larval life to a 24 h. thermoperiodic cycle in constant darkness, individuals of Pieris brassicae L. give diapausing or non-diapausing pupae according

The curve of thermoperiodic induction is similar to the photoperiodic curve. Comparative Endocrinology Effects of TRH on the Release of Immunoreactive a-MSH from Perifused Frog Pituitaries, by Hubert Vaudry, Marie-Christine Trochard, Francois Leboulenger and René Vaillant 961 Intermediate lobes from Rana 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
