Dietary and emotional factors affecting the blood-pressure of cats, observed by exteriorization of the carotid artery



Dietary and emotional factors affecting the blood-pressure of cats, observed by exteriorization of the carotid artery



Quart Jour Exp Physiol 26(2): 155-164



An operative procedure is described for exteriorizing the carotid artery of cats. The normal carotid pressure, measured by a modified Riva-Rocci method, is 140-170 mm. Hg. On a diet of raw meat, 200 gm. a day, the blood-pressure is lower (130-140) and the weight increases by about 20%. On a milk diet (300 cc. a day), the blood-pressure is higher (150-170) and the weight decreases to its former value. Addition of 0.8 gm. his-tidine to the milk has no marked effect on blood-pressure. Emotional changes are accompanied by a rise in blood-pressure, e.g., on seeing a mouse, to 220 mm. Hg. or on hearing a blue-bottle to 190 mm. Hg.
