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 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 Aniliidae. 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 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 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 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

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 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 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 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 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

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 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 projected onto lobule VI, and the projections from the raphe nuclei onto lobule VII. 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 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 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 the Inhibition of the Stimulatory Membrane Repolarization and the Positive Inotropic Response Caused by Ouabain in Rat Myocardium, by Jacques Diaconu and Jean Dicrich.

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 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 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

Endocrinology A Study by Radio-Immunoassay of the Hormonal Activity of the Testicular Interstitial 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 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.

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 ± 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 allows at once, to obtain the cells and to study their migration on the artificial surface. 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

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 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 the Ultrastructure of Different Phages and of Protected Protein-Phage Complexes with their Specific Neutralization, by Michele German, Albert German and
