The purpose of the present study was to examine the effect of heating and cooling the forearm muscles on renal vascular responses to ischemic isometric handgrip (IHG). It was hypothesized that heating and cooling the forearm would augment and attenuate, respectively, renal vascular responses to IHG. Renal vascular responses to IHG were studied during forearm heating at 39 degrees C (n = 15, 26 ...
Using the microdialysis technique and laser-Doppler flowmetry, we performed simultaneous measurement of salicylate hydroxylation and glutamate release along with local CBF in the ischemic penumbral cortex of rat brain subjected to normothermic transient middle cerebral artery (MCA) occlusion. Cortical CBF fell to 24 +/- 11% (mean +/- SD) during ischemia and recovered to 84 +/- 16% during reperf...
Optimal timing of therapeutic hypothermia for cardiac ischemia is unknown. Our prior work suggests that ischemia with rapid reperfusion (I/R) in cardiomyocytes can be more damaging than prolonged ischemia alone. Also, these cardiomyocytes demonstrate protein kinase C (PKC) activation and nitric oxide (NO) signaling that confer protection against I/R injury. Thus we hypothesized that hypothermia...
BACKGROUND AND PURPOSE We have recently demonstrated that pretreatment with magnesium (calcium and glutamate antagonist) and tirilazad (antioxidant) in combination with intraischemic mild hypothermia (33 degrees C) (MTH) offers superior neuroprotective efficacy in a rat model of focal transient cerebral ischemia. In the present study, we investigated the time window of this treatment strategy w...
A protective effect of the SOD (superoxide dismutase)-DIVEMA (divinyl ether and maleic anhydride) conjugate on I-R (ischemia-reperfusion) liver injury was demonstrated. Twenty minutes of normothermic hepatic ischemia was induced by clamping the portal triad of Sprague-Dawley rats. Five minutes before the end of ischemia, SOD, SOD-DIVEMA, or NaCl (0.9%) was given intravenously. Using intravital ...
