Contribution of nitrergic nerve in canine gingival reactive hyperemia
Reactive hyperemia reflects a compensatory vasodilation response of the local vasculature in ischemic tissue. The purpose of this study is to clarify the mechanism of regulation of this response in gingival circulation by using pharmacological analysis of reactive hyperemia and histochemical analysis of gingival tissue. Application of pressure to the gingiva was used to create temporary ischemi...
متن کاملAdenosine metabolism in canine myocardial reactive hyperemia.
In pentobrabital-anesthetized open chest dogs, myocardial adenosine content is elevated by 5 or 15 seconds of left coronary artery occlusion and falls exponentially to control levels during reactive hyperemia. The rate constants for adenosine dissipation are (mean +/- SEM): -0.08 +/- 0.01 and -0.034 +/- 0.007 sec-1 after 5- and 15-second occlusion, respectively. Kinetic analysis of the reactive...
متن کاملCharacteristics of Reactive Hyperemia in the Canine Intestine.
• Although many studies have dealt with postocclusion ("reactive") hyperemia in skeletal muscles," and a considerable number with such hyperemia in the coronary " and renal circulations," little systematic study of this phenomenon appears to have been made on the intestinal circulation. Since this vascular bed has received considerable attention in relation to intestinal ischemic shock," endoto...
متن کاملContribution of anaerobic metabolism to reactive hyperemia in skeletal muscle.
Elevated blood flow (reactive hyperemia) is seen in many organs after a period of blood flow stoppage. This hyperemia is often considered to be due in part to a shift to anaerobic metabolism during tissue hypoxia. The aim of our study was to test this hypothesis in skeletal muscle. For this purpose we measured NADH fluorescence at localized tissue areas in cat sartorius muscle during and after ...
متن کاملIntracoronary adenosine deaminase reduces canine myocardial reactive hyperemia.
We employed intracoronary infusions of calf intestine adenosine deaminase (ADA) to test the hypothesis that adenosine regulates coronary blood flow during myocardial reactive hyperemia (RH). Infusions of 4.5 U ADA/min per kg body weight into the left circumflex coronary artery of 10 open-chest dogs reversibly reduced repayment of flow debt by 30-39% (P less than 0.05) following 5-, 10-, 15-, 20...
