Response of the microcirculation in rat cremaster muscle to peripheral and central sympathetic stimulation.
Microvascular diameter and flow responses to peripheral and central sympathetic stimulation were measured in different segments of the arteriolar network in rat cremaster muscle. For peripheral stimulation, a bipolar electrode was placed on the internodal segment of the lumbar sympathetic chain between ganglia L1 and L2. For central stimulation, a bipolar electrode was stereotaxically implanted...
متن کاملLeukocyte-endothelial adhesion is impaired in the cremaster muscle microcirculation of the copper-deficient rat.
Dietary copper deficiency impairs the function of both the vascular endothelium and circulating leukocytes. In the current study, leukocyte-endothelium adhesion was observed in the in vivo cremaster muscle microcirculation of copper-adequate and copper-deficient rats. Male, weanling Sprague-Dawley rats were fed purified diets that were either adequate (5.6 microg/g) or deficient (0.3 microg/g) ...
متن کاملEffects of vasodilators on microcirculation of the rat cremaster muscle: a microscopic method for screening drugs.
Effects of vasodilating drugs on microcirculation of the rat cremaster muscle were investigated microscopically. Topical application and intravenous injection of papaverine produced dilatation of arterioles. Cyclandelate applied topically dilated the arterioles to a considerable extent. Topical application of bamethan induced arteriolar dilatation while bamethan given intravenously constricted ...
متن کاملMechanisms of cell injury in rat mesentery and cremaster muscle.
The events responsible for cell injury after a tissue stimulation are only incompletely understood. The purpose of this study was to examine mechanisms of cell injury in two tissues, rat mesentery and cremaster muscle, after tissue stimulation with N-formylmethionyl-leucyl-phenylalanine (FMLP) and platelet-activating factor (PAF). The response was studied in the same animal in random order usin...
متن کاملInterleukin 2 acutely induces platelet and neutrophil-endothelial adherence and macromolecular leakage.
The acute effects of interleukin 2 (IL-2) were determined in the rat cremaster microcirculation model by intravital, light, and electron microscopy to better understand the pathophysiology of the IL-2-induced vascular leak syndrome. Four groups of rats were studied over a 2-h monitoring period. One group received 1 x 10(6) units of IL-2/kg i.v. (n = 10), while the remaining groups received IL-2...
