Résués Les effets de l'uranium sur l'excrétion de la glycoprotéine urinaire principale du rat out été étudiés chez 10 animaux. La principale glycoprotéine urinaire augmente de 50% dans les 24 h qui suivent l'administration de l'uranium.

Résumé Les études faites au microscope électronique sur les reins de rats marqués in vivo à l'argent et colorés in vitro au rouge de ruthenium ont montré qu'une partie de la membrane de base glomérulaire rénale est constituée par les cellules épithéliale viscérales. Cette partie est sécrétée de la même manière et en même temps que la couche cellulaire recouvrant les cellules viscérales et sa coloration est semblable. 相似文献

A method allowing simultaneous isolation of Rabbit alomerular and tubular basement membranes has been perfected. Rabbit tubular basement membrane has also been obtained by tryptic digestion of the renal cortex. Electron microscopic observation and biochemical analysis show that the contamination of the membrane preparations by cellular components is negligible. 相似文献

Immunodiffusion technique, with rabbits antibodies against rat glomerular basement membrane (GBM), permits to evidence the presence of GBM antigens into normal urines of 3 rodents (rat, mouse, and guinea-pig). These results confirm the earlier works in human and rabbit urines and show the antigenic communauty existing between the 3 rodents GBM, since we can evidence antigens of 3 different mammals with the same antibody. The origin and the nature of this patterns and the signification of this presence into mammalian urines are discussed. 相似文献

Zusammenfassung Mehrere Faktoren wurden untersucht, die verantwortlich sind für die Dickenvariabilität der Glomerulisbasalmembran der Rattenniere unter verschiedenen, nicht pathologischen Bedingungen. Durchschnittsdicke und Frequenzverbreitungskurve der Basalmembran ändern sich in Abhängigkeit vom Nierenzustand. 相似文献

A fine quantitative evaluation of ferritin aggregates in rat GBM permits to counts 5.08 +/- 1.51 and 18.30 +/- 3.21 g/cm2, respectively 30 and 60 min after ferritin injection; likewise, 30 min after ferritin administration, 5.08 +/- 1.51 and 17.11 +/- 3.9 g/cm2, respectively in normal and theophylline-treated animals. 相似文献

A nephropathy affecting both tubules and glomeruli has been induced in Rabbits by the injection of an heterologous immune serum directed against Rabbit tubular basement membrane. It differs from experimental antiglomerular basement membrane nephropathy by the fixation of antibodies and C3 on tubular basement membrane and by the occurrence of glucosuria. 相似文献

Summary The chemical composition of liver plasma membrane was studied in Wistar rats aged between 3 and 24 months. Results obtained indicate a significant age-dependent positive correlation of both the protein:phospholipid and cholesterol:phospholipid ratios, whereas the protein:cholesterol ratio seems to remain unaffected. Phospholipid analysis of liver plasma membrane reveals that only the phosphatidylcholine content has a significant negative correlation with age; all other phospholipid species remain basically unchanged.Supported by a grant of the Italian National Research Council, Project Preventive and Rehabilitative Medicine, Subproject Mechanisms of Aging. 相似文献

Zusammenfassung Der Einfluss von Coffein auf Kontraktion und Membranpotential des Atriums der Ratte ergibt: Verkürzung der Dauer des Aktionspotentials und Beschleunigung der Geschwindigkeit von Repolarisation und Depolarisation. Ein möglicher Zusammenhang dieser Änderungen mit der erhöhten Kontraktilität wird diskutiert.

Riassunto Gli Autori hanno dimostrato mediante immunofluorescenza la positività immunologica della parete tubulare del testicolo umano, in un caso di azoospermia. Questo reperto si presta ad interessanti considerazioni riguardo al ruolo svolto dalla membrana basale della parete tubulare nelle malattie autoimmunologiche del testicolo. 相似文献

Zusammenfassung Kaninchenantisera, mit Antikörpern gegen Basalmembranantigene menschlicher Niere und Plazenta, wurden, bei Anwendung der Coonsschen fluoreszierenden Antikörpermethode zur Bestimmung von heterogenen Antigenen in vier anderen Spezies, angewandt. Es wurde nachgewiesen, dass die glomerulären und tubulären Basalmembrane der Meerschweinchen- und Mausniere ein oder mehrere Antigene enthalten, welche mit Antihumannierenserum und Antihumanplazentaserum eine Kreuzreaktion zeigen.

Zusammenfassung Das natürliche an Bentonit adsorbierbare «Co-opsonin», welches für eine optimale Phagocytose virulenter Streptokokken der Gruppe A nötig ist, erweist sich als verschieden von Lysozym. Es liegen Hinweise vor, dass das «Co-opsonin» in der-Lipoprotein-Fraktion des Serums vorliegt. 相似文献
