Botany Delimitation and Classification of the Strophariaceae Sing. and Smith (Agaricales) in the Light of New Research on the Structure of their Pigments, by Katia Gluchoff-Fiasson and Robert Kühner 1667 Systematic study of the distribution of styrylpyrones and derivatives among the Strophariaceae Sing, and Smith and related genera: taxonomic incidences. Vegetable Cytophysiology Autoradiographic Study of Protein Synthesis Recovery in Root Cells of Zea mays Embryos During Early Stages of Germination, by Roger Delteil 1673 Recovery of protein synthesis was studied in primary root of germinating Zea mays embryos. [H] leucine or [H] lysine was provided for two hours at 16°C to embryos excised from kernels at various times after the beginning of germination. Protein synthesis (probably dependent on long-lived mRNAs stocked in dormant embryo root cells) resumed during the first two hours of seed imbibition. Physiology Evidence of an Alpha Adrenergic Effect over Isolated Fat Cells of Canine Adipose Tissue, by Michel Berlan 1677 Phentolamine, an alpha blocking agent, potentializes the adrenaline-gic-al lipolytic effect of isolated fat cells of Canine omental adipose tissue when their average diameter is greater than 80 μm. This effect can be found also in isolated fat cells of mesenteric adipose tissue, spontaneously less sensitive with catecholamines. Phenylephrine, alpha sympathomimetic, partially inhibits the lipolytic effect stimulated by isoprenaline. Uptake and Incorporation of Labeled Oleic Acid and Glycerol by Isolated and Perfused Liver of Wistar Rats, by Françoise Chanussot and Gerard Debref 1681 After perfusion by oleic acid (9-10H) and glycerol (14C) previously starved Wistar Rats, the synthesis of hepatic TG and PL follows the two following different methods: — during the first minutes of perfusions, the most important method of synthesis of TG and especially of PL is a de novo synthesis utilizing glycerol and the exogenous AG. The TG synthesized are 18:1 18:1 18:1 and 16:0 18:1 18:2 the PL synthesized are PE, AP and LPC: — during perfusions of long duration (30, 60, 120 min.), the major method of synthesis of TG and

Insect Physiology Influence of Photoperiodism on the Length of the Wing of a Cricket from Algeria, by Jacques Rouault and Suzel Fautrel-Braesch 1685 The morphometric study of a cricket from the Haute Plateaux of Algeria is made by discriminant analyses with 15 characters. Different experimental populations are submitted to various photoperiods for two generations. Only the wing is sensitive to the photoperiod: its length reflects the conditions of life of parents and offspring without any connection with the problem of diapause. Effects of Irradiation of Bombyx mori Larvae on the Evolution of Ecdysteroid Titer in Hemolymph and Ecdysone Metabolism, by Madeleine Coulon and René Feyereisen 1699 Second and third instar larvae of B. mori show a peak of ecdysteroids in the hemolymph towards the end of each instar. Second instar larvae which are X-ray treated at 0 h die at the third ecdysis. In these larvae, titer and metabolism of ecdysone is disturbed. Larvae X-ray treated at 24 h in the second instar mostly become permanent larvae of the third instar,

Larvae X-ray treated at 24 h in the second instar mostly become permanent larvae of the third instar, having a very low level of circulating ecdysteroids, which hardly metabolize injected ecdysone. Biology Influence of Temperature on the Respiration of Pieris Brassicae (Lepidoptera) Diapausing and Non-Diapausing Pupae, by Jacques Fourche 1693 In Pieris non diapausing pupae the respiratory rate follows a sigmoid curve with respect to temperatures from 5 to 35 °C. A similar curve can be observed but only immediately after molt in diapausing pupae. When the steady diapausing metabolism is established, respiratory rate follows an exponential curve. In this later case it is assumed that velocity of one respiratory enzyme is the limiting step; the access to substrates is then non limiting. Experimental Biology Osteopetrosis Cured by Allogenic Bone Marrow Injection in the "op" Rat, by René Moutier, Kiyoko Toyama and Henri Lamendin 1697 The cure of the osteopetrotic syndrome in "op" rats has been obtained by allogenic bone marrow injection following appropriate irradiation of the mutant recipients. Experimental Biology Mitotic Activity in Glandular Epithelium of the Small Intestine after Radio-frequency Lesions of the Hypothalamic Tubero-infundibular Region and Simultaneous Pinealectomy in the Rat, by Mauro Bindoni, Stefania Sianzani, Antonio Bava and Natalino Belluardo 1701 Radio-frequency lesions of the tubero-infundibular region of the hypothalamus and simultaneous pinealectomy are

The double operation is followed by a significant increase of mitotic rate in the small intestine glandular epithelium. This increase is higher than the addition of the effects that are caused by each operation. Oceanology Association of Stromatolitic Structures and of Encrusting Foraminifera in a Ferromanganese Crust with Granitic Core from the North Atlantic, by Andre Schaaf, Michel Hoffert, Anne-Marie Karpoff and Denis Wirrmann 1705 Encrusting benthic foraminifera are intimately associated with ferromanganese crusts which occur on fragments of Hercynian altered granodiorite. Paleontological evidence suggests that the crusts are recent and thus have formed rapidly, most likely in deep water bottoms of the Atlantic Ocean. Embryology Involution of the Mesonephros and Differentiation of the Epididymis in the Chick: an Immunohistological Study, by Yvon Croisille, Madeleine Gumpel-Pinot and Jean-Marie Gasc 1709 By means of purified Rabbit anti-adult Chicken kidney antibodies two types of antigens have been identified in the mesonephros: one, localized in the cells of the proximal segment of the secretory tubules, the other characteristic of the collecting segments derived from the Wolffian duct. During the transformation of certain mesonephric tubules into ductuli efferentes and conjugentes of the epididymis, the collecting tubule antigen disappears, whereas the proximal

During the transformation of certain mesonephric tubules into ductuli efferentes and conjugentes of the epididymis, the collecting tubule antigen disappears, whereas the proximal secretory tubule antigen not only persists but can also be detected in the parietal layer of Bowman's capsules as they transform before connecting with the rete testis. Experimental Embryology Mesoderm and Primordial Germ Cells Induction by the Endoderm in Pleurodeles waltii (Urodele Amphibian): Evolution during Gastrulation, by Jean-Pierre Maufroid and Alfred Capuron. Blastula ectoderm is combined with dorsal or ventral endoderm from blastulae, gastrulae and early neurulae. In vitro culture reveals the presence of different mesodermal structures whose nature is connected with the endoderm origin site. Primordial germ cells differentiate essentially in the recombinates including ventral endoderm. The inducing capacity of this latter concerning germ cells is maximum at the beginning of gastrulation, then decreases during it and finally disappears at the onset of neurulation. Ecology The Resistance of Chironomidae Orthocladiinae to Soil Desiccation, by Yannick-R. Delettre and Simone Bail Hot. Larvae of Parasmittia sp. effect the totality of their growth in winter, when the pioneer formation substratum (Armorican moorland) is saturated with water. In summer, they adopt a form of resistance in deeply placed cellules which enables them to support a desiccation reaching pF 6. The imagos emerge in autumn. Three years of trapping furnish similar results. Ecophysiology Study

Ecophysiology Study on the Nitrogen Content and the Composition of Amino-Acids in the Tissues of some Armorican Littorinidae (Molluscs, Mesogastropods), by Jacques Daguzan. The nitrogen content is high in all the species of the family Littorinidae (Littorina neritoides, L. saxatilis, L. littorea, L. littoralis) which exist on the Brittany coasts. The composition of the amino-acids present in the tissues of animals is also rather homogeneous, the most important aminos of which are: aspartic acid, glutamic acid and glycine. Cystine seems to be more abundant in the species which inhabit the highest levels of the intertidal zone. Biochemistry Characterization of a 5a-Androstan-3β, 17β-Diol Receptor in the Cytosol from Anterior Hypophysis of Prepubertal Male Rats, by Marise-Lise Thieulant, Suzanne Samperez and Pierre Jouan. The presence of a "specific receptor for 5a-androstan-3β,17β-diol (Dihydrodiol) in the pituitary cytosol from prepubertal male rats was demonstrated. Its characteristics were: KA = 5.2 107 M-, Ko = 1.9. 10-8 M, number of specific binding sites = 8.7. 10 14 moles per mg of proteins. Its sedimentation constant was 3 S. Competition assays showed that only 3β-diol itself and estrogens were able to compete for the binding sites for 3β-diol. Androgens, including 3β-diol, were inefficient. This receptor was found only

This receptor was found only in pituitary cytosol, it was missing from hypothalamic or cortical cytosols. This special localization seemed to foreshadow a specific role for 3β-diol in the anterior hypophysis. Bacteriology Problems Arising in Placentalase Isoelectric Points Determination, by Roger Labia and Michel Barthelemy. Analytical isoelectric focusing in polyacrylamide gels and preparative electrofocusing in density gradients may give very different pi determination for the same Placentalase. This difference seems due to a lack of enzyme migration in some parts of the cross-linked polyacrylamide gel. This migration appears easier in density gradient isoelectric focusing, and thus this technique yields more significant absolute pi values. Analytical isoelectric focusing should only be used for comparison studies. Genetics Study of HLA Groups in Child Developmental Psychoses and Hypothesis of Enzymopathy, by Bernard Golse, Pierre Debray-Ritzen, Jean Dausset, Marc Lipinski and Jacques Hors. The HLA typing (loci A and B) of a series of fifteen psychotic children has shown an increase of the frequency of both HLA-A9 and B5 antigens. These preliminary data and previous biochemical findings in psychotic patients lead the authors to postulate the hypothesis of a qualitative or quantitative anomaly of the superoxide dismutase (SOD-2), the gene of which is situated on the same chromosome (sixth)

Virology Chemical Induction of Murine C-Type Endogenous Viruses. Attempt at Discrimination Based on the pi of the p30 Polypeptide and on the Pattern of Cellular Alteration, by Ivan Laprevotte, Jean-Claude Chuat, Carmen Bernard, Martine Canivet and Catherine Pilon. Endogenous ecotropic and xenotropic murine C-type viruses induced in K-Balb-3T3 cells treated with iododeoxyuridine (IdU) were selected by infection of appropriate indicator cells. The isoelectric point (pi) of the major viral polypeptide (p30) was found to be 6.1 for the ecotropic virus (class I), and 5.7 for the xenotropic virus (class II). An isoelectric form (iso p30) of pi 6.5 was observed in the initial induction peak. In addition, the pattern of cellular alteration in NRK cells at its onset varied according to the pseudotype, the class I pseudotype inducing round cell foci while the foci associated with the class II pseudotype consisted of fusiform cells. Cancerology Suppressor Effect on the Cytotoxicity of Lymphoid Cells from Mice Bearing a Syngeneic Tumor, by Nicole Schaaf-Laurent and Henri Flechet.

When it is tested in vitro, the cytotoxic action of lymphocytes from mice bearing a syngeneic tumor (T2) varies with the age of the graft. At a time when it is very low, the lymphoid cells are cultivated for 3 days and then can be fractionated in two subpopulations on a glass bead column: a cytotoxic "non adherent" group of cells and an "adherent" group that inhibits the activity of the first group when it is added to it.

These are situated along the Huancabamba and Barquisimeto transverse structures in the Andes and along the Parras and Guatemala transverse structures in the Mexican Sierra Madre system. The Caribbean belt, which has evident alpine features, is thus situated in an intercontinental position, at the western end of the Tethys (Mesogean), cut through by the opening of the Atlantic. Petrography Relations between Deformation and Metamorphism in the Skarns of the Contact Aureole of the Querigut plutonic massif (Eastern Pyrenees), by Michel Aparicio 1753 The successive appearance of grossular, vesuvianite and wollastonite from a calcite + diopside + anorthite paragenesis is connected with the progressive deformation of the calcareous surroundings during the forced injection of the magma, the formation of a tectonic sheeting allowing the separation of carbon dioxide. Paleogeography Distribution of Paleoenvironments Relative to Dolomitic Formations in the Vittel-Lamarche area (Southwestern Vosges, France), by Roselyne Ainardi 1757 Inferior Ligoniel dolomitic levels in Southwestern Vosges, present microfacies with characters, sequential evolution and geographical position allowing to set main paleoenvironments. Paleobotany Developmental and Morphological Variability in the Cauline System of Psalixochlaena cylindrica, by John Holmes 1761 The upper Carboniferous fern Psalixochlaena cylindrica possesses a monopodial branching system of axes with occasional isotomous dichotomies. The ontogenetic variability shown by the lateral axillary branches suggests a considerable similarity in growth pattern with some extant ferns. The action of inhibitory influences could explain the existence of short
