Spirobolida, show neurosecretory cells near the globuli I. The whole of his observations induces the author to admit a structural plan common to all the Diplopods: neurosecretory cells of globuli I — (NOG) nerve-neurohemal organ (Gabe's organ). Moreover, he makes an attempt to compare his observations with those concerning another group of Myriapods: the Chilopods. Physiology Speed of in vivo Irreversible Degradation of Free L-threonine in a Case of Lysine Deficiency, by Georges Weillers 819 In adult fully grown rats deficient in L-Lysine, the speed of the irreversible degradation of free L-threonine equals 1.60 mmol/24 h/kg as calculated for 1
free L-threonine equals 1.60 mmol/24 h/kg as calculated for 1 mmol/kg administered. This speed is 23 percent slower than that determined in non lysine deficient animals. This fact explains at least partially, the paradoxical resistance of the adult rat to the lysine deficiency. Effects of Lipid Content of the Diet upon Protein Intake in the Rat, by Francois Piquard, Adrien Schaefer and Pascal Haberey 823 Rats were offered proteins and mixture of carbohydrates and lipids presented in two separate pots. Protein intake increases when the lipid content of the mixture is increased. Endocrinology Plasma, Testis and Adrenal Androgen Concentrations During

Endocrinology Plasma, Testis and Adrenal Androgen Concentrations During the Perinatal Period and Determinism of the High Neonatal Plasma Testosterone Level in the Guinea-Pig, by Guy Pelardy and Paul Delost 827 The perinatal period is characterized in the male fetus and newborn Guinea-Pig by a prenatal increase in testis testosterone and by a neonatal peak in plasma testosterone. This transient rise in plasma testosterone is testis dependent and light dependent at birth. Heterogeneity of Human Calcitonin in Tissues of Medullary Carcinoma of the Thyroid, by Annick Jullienne, Daniel Raulais, Michele Cressent, Moshen S. Moukhtar and Gerard Milhaud 831 In
Michele Cressent, Moshen S. Moukhtar and Gerard Milhaud 831 In an extract of medullary carcinoma of the thyroid several forms of calcitonin are present: aggregates, polymers and big calcitonin; certain forms could behave as hormone precursors. Biology On the Sexual Cycle in Doliolum nationalis (Tunicata) with the First Description of the Oozooid Stage, by Jean-Claude Braconnot 835 The reality of the sexual long cycle concerning Doliolum nationalis in Mediterranean waters off Villefranche (Ligurian Sea) is confirmed with the description of unknown stages for this particular species. A new type of gonophorozoid is identified and the fecundity of the gonophorozoid is
gonophorozoid is identified and the fecundity of the gonophorozoid is proved by breeding the larva from the egg to its fully grown stage as an oozoid, unknown until now. Its description shows us the total similarity between the oozoids of different species of the Doliolum genus (cryptic species for this stage). Experimental Biology Consequences of Experimental Triploidy on the Fertility and Sexual Differentiation of a Normally Amphigonic Diploid Earthworm Eisenia foetida Sav., by Nicole Davant and Francis Andre 839 The fertility of experimental triploid worms has been studied in Eisenia foetida Sav. This study has led us to the conclusion
foetida Sav. This study has led us to the conclusion that the female germ line is abortive while the male germ line may, as an exception, take part in fertilization. Histological controls have confirmed the differentiating ability of the male line and the break in the development of the female line. Experimental Embryology The Population of Germ Cells in the 5 1/2-Day Chick Embryos Following Ultraviolet Irradiation of the Young Blastoderms, by Georges Reynaud, 843 Chick blastoderms, incubated for 5 hrs., were wholly irradiated with ultraviolet light (2 537 A). With ultraviolet doses of 14,400 and 16,200 erg/mm2, the embryos,
With ultraviolet doses of 14,400 and 16,200 erg/mm2, the embryos, often morphologically abnormal, which developed from these blastoderms, were shown to contain, at 5 1/2 days of incubation, very few or no germ cells in the region of their gonad 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.
(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
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
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
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 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
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
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: 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

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
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. Sedimentology Arguments for the Bathymetric Significance of Lateral Variations of Facies in Oolitic Iron Ore from La Ferrière-aux-Etangs (Orne, France), by Georges Courty The lateral variations at La Ferrière denote a bathymetric gradient. 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
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
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
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
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
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
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
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 from a concentration of 3 x 10 -6. 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
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;
phosphorus, sulfur and magnesium occurring within integument and digestive gland; variations related to intermolt cycle can be compared. Cytology Preliminary Report on the Fine Structure of Venom Glands of Asilidae (Diptera-Brachycera), by Claude Donadey and Joseph-Jean Musso 937 The venom gland epithelium of the Asilidae is apparently made up of two types of cells which are differentiated by the structure of some components. 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
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
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
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
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

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
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
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
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,
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 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
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. This method makes it possible to increase the daily administration of smoke considerably; nevertheless, under such conditions, lung tumors were not observed.
