| cardiovascular, respiratory and glottic effects of sodium salicylate administered into different parts of the circulation in rabbits. | the authors studied the effect of sodium salicylate administered into different parts of the circulatory system on various cardiovascular, respiratory and glottic parameters in pentobarbital-anaesthetized rabbits. the results show that apnoea, bradycardia and hypotension, followed by hypertension, can also be caused by the extrathoracic action of salicylate. cardiovascular responses induced by injecting salicylate into the carotid circulation are qualitatively the same, even after vagotomy, as i ... | 1975 | 124883 |

| histochemical fiber typing and staining intensity in cat and rat muscles. | in the gastrocnemius muscle of cat and rat, staining for oxidative enzymes differentiated three fiber types (a,b,c) and staining for adenosine triphosphate at ph 9.4 differentiated two fiber types (i, ii) with a reliability of 90% and 98%, respectively. in cat 96% and in rat 90% of the fibers were typed identically after staining for nicotinamide adenine dinucleotidelinked lactic dehydrogenase (ldh) and succinic dehydrogenase (sdh). when differentiated by staining for ldh, a and b fibers were of ... | 1975 | 125297 |
