Electron microscopic studies on hepatic cells in mice after the administration of glutathione mixtures

Zusammenfassung Anschwellung und Lysis von Mitochondrien im Reagenzglas (in vivo), durch Zugabe von Glutathiongemisch zur Nährlösung verursacht, wurde elektronenmikroskopisch geprüft. Die Mitochondrien wurden in Mäuseleberzellen nach i.p. Injektion zusammen mit dem Glutathiongemisch untersucht.     

Effects of repeated administration of potassium canrenoate (SC-14266) on serum gonadotrophin,prolactin, testosterone and progesterone in male rats

Summary Chronic administration of potassium canrenoate (SC-14266), a water-soluble anti-aldosterone agent, increased serum LH levels in male rats without altering serum levels of FSH, prolactin, testosterone and progesterone. The increase in serum LH may be due to the anti-androgenic effect of potassium canrenoate.Acknowledgments. The authors thank the Rat Pituitary Hormone Distribution Program, NIAMDD, NIH and Dr A.F.

Effect of mitomycin-C on the development of the eye-disks inDrosophila melanogaster

Résumé L'incorporation de l'acétamide-³H et de la thymidine-³H aux disques de l'il a été expérimentée chezDrosophila melanogaster. Ces 2 substances radioactives ont été nettement incorporées dans les disques, mais le traitement avec la mitomycine-C a fait décroître le nombre des grains.     

Continuous deep sea salt layer along North Atlantic margins related to early phase of rifting

Deep seismic reflexion surveys have revealed diapiric structures in deep water off Labrador, Newfoundland, Mauritania, Morocco, Portugal, Spain and Ireland as well as in the Mediterranean. Many of these diapirs are similar to the Gulf of Mexico salt domes, and it is suggested that there is a continuous deep sea salt layer, off the continental margin, which is related to the early phase of rifting.
