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
action of inhibitory influences could explain the existence of short leafy laterals, intermediate types with leafy bases and bearing branches higher up and also of long ramified branches of precocious development. Paleontology Phyletic Position of Dinilysia patagonica, a Snake from the Upper Cretaceous, by Jean-Claude Rage 1765 A dichotomy gave rise to the Aniliidae on one hand, and to the Boidae and the Xenopeltidae on the other hand. Dinilysia does not belong to a divergent phyletic line but to a phyletic line which originated from the main line leading to the Boidae and the Xenopeltidae, after the rise of the

Vegetable Cytology On the Localization, the Fine Structure and the Chemical Composition of Nuclear Inclusions in the Scale-Leaves of Mesophyll Cells of Taxus baccata L., by Serge Renatulin and Al Ichèle Gapteloni 1769 The nuclei of the mesophyll cells contain, near the nucleolus, a voluminous inclusion of stacks of lamellae. Its chemical composition was studied by enzymatic digestion: the use of pronase led to the digestion in ultrathin sections nearly all the nuclear crystal demonstrates that it is primarily composed of protein. Cytology In vitro Analysis of Pollen Tube
composed of protein. Cytology In vitro Analysis of Pollen Tube Growth in Juniperus communis L. (Cupressaceae), by Fluorescent Labelling, by Emile Duhoux 1773 The mechanism of pollen tube growth in J. communis was studied using "Calcein Fluor White M2R" as a vital fluorescent cell wall stain. This method has proved to be easy, rapid and precise. Growth one is found to be apical in young tubes and behind the apex in older ones. Plant Cytophysiology A Lipo-polyphenolic Secretory Kinetic Model Establishment from the Stigma of Forsythia intermedia Zabel, by Christian Dumas 1777 Cytochemical, histochemical and biochemical techniques used together have
Dumas 1777 Cytochemical, histochemical and biochemical techniques used together have permitted us to establish a lipo-polyphenolic secretory kinetic model, mainly eccrine, from the study of Forsythia intermedia Zabel stigma. Plant Physiology Influence of Agar on Absorption and Exsorption of Rubidium by Explants of Jerusalem Artichoke in vitro, by Anny Darpas 1781 The addition of agar to culture media increases both absorption and exsorption of rubidium. This is true for low temperatures also does not seem to depend on the adsorption capacity of the colloid. It could be explained by a reduction of the superficial liquid film which restricts exchange due
reduction of the superficial liquid film which restricts exchange due to diffusion between the medium and the tissue. Pyridine nucleotides in wheat and duckweed cultivated under various conditions (darkness, low energy red light, dichlorophenyl-dimethyl urea), by Jacqueline Vermeersch, Daniel Lechevallier and René Monéger 1781 The reduction charge of wheat etioplasts is not very different from that of chloroplasts, but the reduction rate of NADP and its share in reduced forms are lower by a half. The reduction charge of duckweed chloroplasts, as well as the reduction rate of NADP and its share in reduced forms, decrease in permanent culture under
its share in reduced forms, decrease in permanent culture under weak red light. Duckweed tissues cultivated with DCMU show a fall of reduction charge and of the share of NADP in reduced forms, but the reduction charge and the NADP reduction rate increase in plastids. Plant Biology Vegetative Propagation of the Date Palm (Phoenix dactylifera L.) by Tissue Cultures Obtained from Seedlings, by Saïda Ammar and Abdellatif Benabdes 1793 When endosperm is removed the germination of the Date palm progresses differently according to the medium used for culture. Murashige and Skoog's medium containing indoleacetic acid and 6-benzylaminopurine induces both male
Skoog's medium containing indoleacetic acid and 6-benzylaminopurine induces both male and female inflorescences after a few weeks. If this medium is supplemented with naphthaleneacetic acid, kinetin and coconut milk a callus is formed, especially on the cotyledonary sheath. Tissues sub-cultured from this callus can differentiate into roots and buds. Some plants obtained in this manner have been successfully transplanted to earth. Plant Reproduction Callose and Pectic Substances Distribution Within the Egg Cell Wall of a Gymnosperm Sciadopitys verticillata, by Marcel Gianoli 1793 The cell wall is constituted by two justaposed structures: primary pit fields with a middle lamella and callose
structures: primary pit fields with a middle lamella and callose granules, on the one hand, and, on the other hand, a net-like structure formed by thickening and digitations, both uniformly rich in pectins. This mosaic structure, the distribution of pectic compounds, and the presence of callose are new data: the functional role of these structures is discussed. Genetics Preliminary Investigation on the Diversity of Dormancy States in Several Petunia Lines Seeds, by Frédéric Jasser, Jeannine Monin, André Cornu and Paul Dommergues 1797 We studied the germination abilities of seeds from 25 Petunia lines. The following investigation proves that exist in
25 Petunia lines. The following investigation proves that exist in some lines different and sometimes contrasting dormancy states. In the case of these lines, we investigated also which seed structures might be responsible for this dormancy. Plant Pathology Induced Resistance to Fusarium Wilt by Stimulation of Phenolic Content of Tomato Plants, by Antoine Carrasco, Gerard Marigo and Alain M. Boudet. Feeding potassium quinate to young Tomato plants increases both their phenolic content and their resistance to Fusarium oxysporum. The same results are obtained with phenylalanine, which is a precursor of phenolic metabolism, but other compounds not related to polyphenol synthesis
phenolic metabolism, but other compounds not related to polyphenol synthesis have no effect. These results show the involvement of phenolic compounds in a resistance mechanism, and suggest new possibilities of treatment against infection. Neuroanatomy Projections of Bulbar Reticular Nuclei and of Raphe Nuclei onto Lobules VI and VII of the Cerebellar Cortex in the Cat, by Cesira Batini, Jocelyne Corvisier, Olivier Hardy and Dora Jassik-Cerschenfeld. Injections of horseradish peroxidase were made in lobules VI and VII of the cerebellar hemispheres in the Cat. Serial frontal sections of the brain stem reveal that the lateral reticular and paramedian nuclei were essentially

Histology Simultaneous Evidence for Ocellar Neurons and Neuro-secretory Cells on Wholemounts in the Pars of the Cockroach Periplaneta americana, by Anne Bernard. Our bulk-staining method results from the combination of techniques using both cobalt chloride iontophoresis and paraldehyde fuchsin. The observation of medial neuro-secretory cells and ocellar neurons in the pars on the same wholemount would show no direct connexion between these two systems in the Cockroach Periplaneta americana. Cytogenetics Chromosomic Structures and Polygenotypism in Bilobella
Cockroach Periplaneta americana. Cytogenetics Chromosomic Structures and Polygenotypism in Bilobella aurantiaca Caroli (Collembola) of French Cerdagne, by Henri Dalens. Short polytene chromosomes of Bilobella aurantiaca show a characteristic structural pattern. Differences between populations are associated with hand structuration, quantity of heterochromatin and longitudinal cleavage. Variations within populations are also present and these do not correlate with the degree of polyteny. One of the populations shows short polytene chromosomes belonging to two different structural patterns. Physiology Study on the Genetic Activity of the Mouse Oocyte During Its in vitro "Spontaneous" Maturation, by Henri Alexandre and Yves Gerin. Mouse oocytes, liberated from
by Henri Alexandre and Yves Gerin. Mouse oocytes, liberated from ovarian follicles, resume meiosis in the obligatory presence of Ca++. Phosphates exert a toxic effect on this mechanism. m-RNA synthesis, in contrast to that of r-RNA, seems to be required during the first hours of maturation in order to ensure realization of the following steps; in addition, the 2nd maturation period, corresponding to the polar body extrusion, depends on the presence of proteins synthesized during the chromatin condensation process and germinal vesicle breakdown. We suggest that it might be a factor responsible for chromosome formation in metaphase I. Correlation Between
factor responsible for chromosome formation in metaphase I. Correlation Between the Inhibition of the Stimulatory Membrane Repolarization and the Positive Inotropic Response Caused by Ouabain in Rat Myocardium, by Jacques Diaconu and Jean Dicrich. During a stimulus train, the diastolic membrane potential of rat atria exhibits a depolarization phase followed by a slower repolarization phase which has been attributed to the activation of an electrogenic sodium pump (ATPase Na+, K+). This pump seems to be all the more active as stimulation frequency is higher. The parallel evolution of the sodium pump inhibition and a positive inotropic effect in response to
pump inhibition and a positive inotropic effect in response to ouabain perfusion, suggests that the enzymatic inhibition is directly involved in the development of the cardiotonic effect of digitalis. Physiology Repair of a Fundo-Antral Gastric Fistula with a Fundo-Antral Homologous or Heterologous Transplant in Adult Rat, by Hung Le Van, Nin Khieu and Tuyet Nga Duong. Use of fundo-antral gastric transplants excised from Rat or guinea-pig stomach in order to repair fundo-antral fistula was well tolerated by adult Rats and compatible with a normal survival. In 90% of homologous transplantation, and 70% of heterologous transplantation, no brutal and mortal rejection
and 70% of heterologous transplantation, no brutal and mortal rejection of transplant was observed. The transplant did not regenerate, but its corpse was not eliminated, and remained united to the wall of the receiver's stomach, and infiltrated with lymphocytes. We explain the benignity of immunologic reaction in evoking the role of the liver which acts as a filter in sequestering a great part of antigens, and so moderating the antibody response by the spleen and lymphoid system. Endocrinology A Study by Radio-Immunoassay of the Hormonal Activity of the Testicular Interstitial Tissue from Gobius niger L. in Organotypic Culture: Spontaneous Activity
Tissue from Gobius niger L. in Organotypic Culture: Spontaneous Activity and Stimulation through Pituitaries, by Jean-Pierre Bonnin. After the interstitial tissue was cultivated, the radioimmunoassay revealed in the media very small quantities of free testosterone but much larger quantities of testosterone conjugates as glucuronides and sulfates. Association of pituitaries increases greatly the secretion. 12-13 days precultivated pituitaries retain close to 70% of their stimulating potency. Invertebrate Endocrinology Cytochrome P-450 and Hydroxylation of Ecdysone to Ecdysterone in Locusta migratoria in vitro, by René Ferrasolisen. Microsomes from locust fat body and Malpighian tubules convert ecdysone to ecdysterone. This reaction is O2 and
tubules convert ecdysone to ecdysterone. This reaction is O2 and NADPH dependent and is inhibited by carbon monoxide. Ecdysone produces a type I spectral change when added to microsomes which contain cytochrome P-450. It is concluded that a cytochrome P-450 species is responsible for ecdysone hydroxylation. Neurophysiology Reduction of Efferent Renal Nerve Activity by Propranolol in the Rabbit, by Alain Friggi, Anne-Marie Chevalier-Cholat and Jean Torresani. During intravenous infusion of propranolol (0.3-0.8 mg/kg) in the Rabbit, systolic arterial pressure is decreased (-6.5 ± 4.2 mmHg) and electrical activity recorded from central end of the renal nerve is reduced significantly (-8.7
central end of the renal nerve is reduced significantly (-8.7 ± 14.0%) with regard to the activity obtained, at the same pressure levels, by hemorrhage (+ 7.9 ± 6.4 %; p < 0.25) or by intravenous infusion of the peripheral vasodilator sodium nitroprusside (+ 14.1 ± 9.9 %; p < 0.01). Cellular Biology In vitro Study of the Cellular Affinity of Different Protein Supports which Could be Used as Vascular Prostheses, by Marie-Françoise Sigot-Luizard and Michel Sigot. We compare the affinity of different cellular samples with regard to various artificial materials by organotypic culture method. We use a technique which

The results show a high variation of the cellular affinity from one sample to another. Biochemistry Location of the Single Cysteine Residue in the Primary Structure of Yeast 3-Phosphoglycerate Kinase, by Abdellatif Fattoum, Jeanne Feinberg, Gisèle Desvages and Claude Roustan. In order to study the location of the single cysteine residue in the primary structure of yeast 3-phosphoglycerate kinase, cyanation by 2-nitro-5-thiocyanobenzoic acid has been carried out. Analysis of the two fragments obtained shows
been carried out. Analysis of the two fragments obtained shows that the -SH group is located near position 100. Pharmacology An Unexpected Increase of the Antibiotic Properties of a Cephalosporin, by Robert Bucourt, René Duchêne, André Lutz, Lucien Penasse and Jacques Froloff. The presence of an oximino group on the methylene of the (2-aminothiazol-4-yl)-acetyl side chain bound to the 1-amino cephalosporanic acid affords derivatives with syn or anti configuration. While the anti isomers display low antibiotic activities, the syn isomers possess a surprisingly high efficiency against gram negative bacteria, enhanced by a factor of 10 to 100 as compared with
by a factor of 10 to 100 as compared with the cephalosporins known at the moment. Microbiology A Study of Bacteriophages of Rhizobium meliloti, by Michel Werquin, Mohamed Tahar Ben Brahim and Draga Krsmanovic-Simic. Back to our technique of phage sensitization by protein fixation with the aid of coupling reagents, and of their inactivation by the specific anti-protein antibodies, comparative studies were made on phages having a morphologically different tail. Here we report the results concerning the ultramicroscopic observation of four phages, the efficiency and the rate of their sensitization, and the possibility of their respective neutralization. Virology Relationships Between
and the possibility of their respective neutralization. Virology Relationships Between the Ultrastructure of Different Phages and of Protected Protein-Phage Complexes with their Specific Neutralization, by Michele German, Albert German and Marie-Joseph Danse. Among the bacteriophages in our collection, seven are studied which can lyse Rhizobium meliloti in a liquid medium in the absence of Ca2+ or Mg2+. The total of their properties clearly differentiates them from phages which are unable to lyse Rhizobium meliloti under identical conditions.

SECTION D No. 19 — SESSION OF MAY 16th 1977 Petrology CO2, H2O and the Genesis of Alkali Basalts of the Massif Central (France), by Emmanuel Berger. Free CO2 resulting from decarbonation of the upper mantle during adiabatic uprising and, to a lesser degree, pre-existing H2O traces (which probably resulted from the breakup of phlogopite) together allowed partial melting which in turn generated the French Massif Central alkali basalts. Geology The Time Factor and Abundance of Granitoids in Folded Chains, by Boris Choubert. Setting up of a tectonic map of the continents and the measurement of the areas occupied by
the continents and the measurement of the areas occupied by the granitoids reveal a strong correlation between the abundance and radiometric age of these rocks. What is the significance of this statement? Structural Geology Tethyan-Atlantic Alternate Pulsations: a Key to Earth History, by Henri Termier and Geneviève Termier. Here is an attempted global and synoptic history of two ancient structures which underwent alternate phases of opening and closing. Such a balancing has conditioned relief and climate as well as the peopling of seas and emerged lands during the whole of geological times. Geology-Prehistory Discovery of an old lithic industry in
geological times. Geology-Prehistory Discovery of an old lithic industry in situ in the Hadar formation, Central Afar, Ethiopia, by Hélène Roche and Jean-Jacques Tiercelin. During the fifth International Afar Expedition (1976), some pebble tools (choppers, polyhedrals, cores, flakes) were discovered in two conglomerates of the upper part of the Hadar formation. These conglomerates, included in deltaic and marsh units, have a possible age of 2.6 M years. Volcanology A Post-Villafranchian Pumice Flow on the Eastern Side of Mont-Dore (Massif Central), by Jean-Claude Besson, Meng Hour Ly, Jean-Marie Cantagrel, Alain de Goer de Herve and Pierre M. Vincent. Outcrops of a
Goer de Herve and Pierre M. Vincent. Outcrops of a pumice flow deposit of trachytic composition, channelled in old valleys on the eastern flank of Mont-Dore, were found as far away as Neschers, not far from the Allier river, 30 km from the suspected vents in Sancy massif. Potassium-Argon measurements give ages c.a. 800,000 Y. Mycology Growth and sporulation of Entomophthora virulenta Hall and Dunn in batch culture, by Jean-Paul Latge. Fermented cultures of Entomophthora virulenta showed an exponential phase with a specific growth rate of 0.14 h-. The deceleration phase was 4 times longer than the exponential phase. Sexual
phase was 4 times longer than the exponential phase. Sexual sporulation occurred at the end of the deceleration phase. A technique of medium replacement demonstrated that any lack of nutritive balance induced the sporulation. Plant Histophysiology Effects of Auxins and Antiauxins upon the Neoformation of Vegetative or Inflorescence Buds of Brassica oleracea L., var botrytis, by Jacques Margara. Several auxins and antiauxins induce bud neoformation on explants of cauliflower heads. The percentage of neoformations is increased by traumatic acid. According to its concentration, gibberellin A3 stimulates or inhibits bud neoformation induced by auxin. Several antiauxins can sporadically elicit flower neoformation
induced by auxin. Several antiauxins can sporadically elicit flower neoformation without previous head formation. Plant Physiology Variation of the Isotopic Composition of Organic Oxygen of Several Plants as a Function of their Environment, by André Ferhi and René Letolle. Oxygen isotope content of organic matter taken from plants grown under various climatic conditions shows important variations related to the ecology and perhaps to the photosynthetic pathways. 180/160 Ratio in Plant Organic Substances, by Jacques Bricout. The ratio of the two stable isotopes of oxygen 180/160 was shown to be higher in different organic substances derived from plants than in their
in different organic substances derived from plants than in their water. This observation correlates the general assumption that the oxygen in vegetal organic material is derived from carbon dioxide. Some differences in the "O content were also observed in organic substances which are biosynthesized by different pathways. Zoology Elementary microanalysis of the shell of Euglypha (Testacea), by Colette Jeanson and Marie-Madeleine Couteaux. Analyses preserving the structure of the shells were carried out with the microprobe analyzer and scanning electron microscope probe. The result shows nine elements: Al, Si, and Fe in greater quantity and traces of Ca, Ti, S, Ni,
in greater quantity and traces of Ca, Ti, S, Ni, P, Cu. Entomology Influence of temperature and food on caste determination in the Ant Aphaenogaster senilis, by André Ledoux 1899 Inhibition due to the Queen can be stopped either by the action of the thermoperiod with important differences of temperature or by the adjunction of vitamins in the normal food. In the colonies without queen, the number of new winged females is increased by the action of these two factors. Insects Physiology Study of the Influence of Diapause on the Acquisition of Flight Capability in Colorado Potato Beetle: Leptinotarsa decemlineata
Acquisition of Flight Capability in Colorado Potato Beetle: Leptinotarsa decemlineata (Say), by Michel Termier 1903 The method consists to observe flight initiation on glued beetle. Those animals were of various ages and have been raised in short or long day. The Leptinotarsa of long day condition avoid diapause and they become quickly able of good flight performances. Those of short day condition are obliged to enter in diapause and perform, very much later, not as good flight performances as those of the other category. Incorporation of tritiated Uridine in the ovarian cells of an adult insect, Ulopa reticulata Fab. (Homoptera
ovarian cells of an adult insect, Ulopa reticulata Fab. (Homoptera Auchenorrhyncha), by Claude Hamon 1907 The tritiated Uridine incorporation in the acrotrophic ovary of Ulopa reticulata shows that there are two different organs for the RNA of the ovocyte cytoplasm: the ovocyte nucleus, and the trophic cells (by way of the trophic cords). Endocrinology Presence of neurosensitive contacts and of a new type of synapse in the pineal gland of a lizard (Lacerta muralis Laurenti) by André Petit and Berthe Vivien-Roels 1911 The neurosensitive synapses between photoreceptor cells and nerve ganglion cells are numerous enough to constitute an additional argument
ganglion cells are numerous enough to constitute an additional argument for a photosensitive function of the pineal gland. A new type of synapse, observed between the secretory rudimentary photoreceptor cells and nerve ganglion cells presents a direct relation from cells showing an active secretory function to the central nervous system. Marine Biology Experimental Confirmation of the Role of a Benthic Diatom, Navicula ramosissima (Agardh) Cleve, in the Secretion of Mucoidal Materials Which Stabilize Muddy Marine Littoral Flats, by Jean-Michel Robert and Dominique Gouleau 1915 Maintained in unialgal culture on an artificial substratum, Navicula ramosissima (Agardh) Cleve constitutes a colonial "archeothallus".
artificial substratum, Navicula ramosissima (Agardh) Cleve constitutes a colonial "archeothallus". Observations made with the scanning electron microscope allow us to follow the formation of the mucoidal threads which constitute it. This study enables us to confirm that the mucoidal materials are in fact produced by the Diatoms and are effective stabilizers of the muddy marine littoral flats in the Bay of Bourgneuf. Developmental Biology Monovalent Fragments of Rabbit Anti-F9 Immuno-Globulins Prevent the Formation of Blastocyst in the Mouse, by Charles Babinet, Rolf Kemler, Philippe Dubois and François Jacob 1919 Fab fragments of a Rabbit anti-F9 serum do not disturb cleavage
