Relation between work and labile phosphate content in the isolated dog heart.
Starling heart-lung preparations of the dog (with only minor differences in heart rate) were subjected to changes in work load to study their effect on the amount of labile phosphate in the left ventricle. While increasing the work load three to fourfold by increasing output caused no change, doubling the work load by increasing the resistance was accompanied by a marked reduction in labile pho...
متن کاملthe relationship between learners critical thinking ability and their performance in the reading sections of the tofel and ielts test
the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...
15 صفحه اولEffects of Low Level of Lead Exposure on Responsiveness of The Rat Isolated Heart to Adrenergics
Background: There are controversial reports about the exact mechanisms of lead-induced hypertension, but many factors such as alteration in the responsiveness of cardiovascular system to endogenous substances including catecholamines could be one of the mechanisms involved. In present study, the effect of exposure to 100 ppm lead acetate by drinking water (in the periods of 4, 8 and 12 weeks)...
متن کاملEFFECT OF CYANIDE IN CARDIOPLEGIC SOLUTION ON ISOLATED RAT HEART FUNCTION
It has been known that cardiomyocytes possess a remarkable ability to downregulate their energy expenditure on restricted 02 supply. However it has also been speculated that an ability to suppress aerobic respiration and ATP utilization could be a protective response to prolonged hypoxia. Having the role of the cytochrome oxidase enzyme in mind, one can ask if its inhibition by using cyani...
متن کاملEffects of low-level lead exposure on blood pressure and function of the rat isolated heart
OBJECTIVE Exposure to low levels of lead acetate can induce hypertension in both humans and experimental animals. The exact mechanisms of lead-induced hypertension are not well understood, but its pathogenesis could be explained by the changes in heart rate and contractility. MATERIALS AND METHODS In the present study, the effects of exposure to 100 ppm of lead in drinking water (for periods ...
