1972 — Cortico-nuclear projections from the paramedian lobule and Crus II of the cat cerebellum; an experimental study with silver impregnation methodsRésumé
The exact site of termination of fibers from the paramedian lobule and Crus II was investigated by making lesions in these regions and mapping terminal degeneration with the Nauta-Laidlaw method. The paramedian lobule sends three, non-overlapping, ipsilateral projections upon the cerebellar nuclei. The first projection is located in the ventral part of the lateral nucleus (NL), the second in the caudal part of the posterior interposed nucleus (NIP), and the third projection is found in the dorsal portion of the anterior interposed nucleus (NIA) continuing through the NL-NIA transition zone. Crus II sends two ipsilateral projections upon the cerebellar nuclei: … Lire la suite

1972 — Experimental studies on cardiac lesions in renoprival hypertensionRésumé
It is well known that in mammals bilateral nephrectomy results in striking electrolyte changes, hypertension, changes in Gibbs-Donnan equilibria and cell swelling in many organs - consistent with permeability alterations - and progressive irreversible myocardial lesions. To determine the relationships between these events, two groups of bilaterally nephrectomized rats were studied from several points of view. One group was given tap water, and the other 0.5% NaCl to drink after nephrectomy to enhance the changes produced by electrolyte derangements and to accelerate hypertension. In a third group, special permeability alterations were studied in rats treated similarly to group l (tap … Lire la suite

1972 — In vitro phagocytosis of antigen by rat peritoneal exudate cells.Résumé
32P-labelled T2-phage were harvested from a shake culture and purified by CsCl equilibrium density gradient. Peritoneal exudate cells (PEC) were obtained from the peritoneal cavity 72 hrs after i. p. injection of beef heart infusion broth (B.H.I.B.). Anti-T2-phage antisera were prepared in both rats and rabbits. Evidence for the requirement of opsonin (IgM or IgG) from homologous or heterologous sera was provided by using in vitro sensitized antigen for phagocytosis by rat PEC in vitro. Homologous serum containing 7S IgG antibodies provided the highest degree of enhancement of antigen uptake by rat PEC. The specific opsonin was isolated by starch … Lire la suite
