Histopathological Studies about the Experimental Hypertension (ESPECIALLY, ON THE KIDNEY, HEART AND BLOOD VESSELS) II : PART III HISTOPATHOLOGICAL STUDIES ON THE EXPERIMENTAL RENAL HYPERTENSION

Studies on the Renal Arterial Blood Pressure and the Metabolism of Kidney Tissue in Experimental Hypertension

1. In the hypertension which accompanies constriction of the renal arteries, there is no constant relationship between the height of the general systemic arterial pressure and the pressure in the renal artery distal to the point of constriction. The hypertension may persist even though the renal arterial pressure returns to or almost to the control level. 2. Studies on the renal blood flow and ...

Studies on Experimental Hypertension

1. Extraction of finely ground fresh hog kidney with distilled water adjusted to pH 7.8 with sodium hydroxide, followed by successive treatment, as described, with trichloroacetic acid and acetone, gives renin in good yield of a purity suitable for physiological studies and a good starting material for further purification. It contains 15 dog units per mg. N. 2. Further successive purification ...

Experimental studies on intermediate metabolism in the kidney in hypertension.

In recent years, many studies have been made on the metabolism of various substances in hypertensive patients, and it has been established that the high blood pressure is accompanied by some deviations in the meta bolism. The kidney, maintaining a functional correlation with the liver, plays a leading role in the metabolic process in individual organism (Yano,l) Hecht,2) Saiki,3) Melchier,4) Ka...

Studies on the renal humoral mechanism of chronic experimental hypertension.

IN PREVIOUS investigations we have shown that the renin content of the blood and of the kidneys of patients with hypertension and of dogs with chronic hypertension due to renal ischemia is similar to that found in controls of both species.1-3 Clamping of the renal artery brings about a rapid increase within the first 20 minutes in the amount of renin in the kidney. This usually reaches a peak w...
