ジャーナル フリーThe study was done to evaluate the renal tubular structure with correlation to enzymatic activities in each cellular organelle such as mitochondria, lysosomes, microsome, at time intervals of one and three hours. Kidney of Wistar King rat sacrificed by decapitation was rapidly removed and incubated with saline (pH 7.0) at 37.. for one or three hours respectively. Enzymatic analysis was detected by following the cell fraction method of Shibko & Tappel. Several enzymes were detected. Enzymatic activities were specifically distributed in cell organelles, In lysosomes, acid phosphatase is prominently positive, cytochrome oxydase is positively reacted in mitochondria, glucose-6-phosphatase in microsomes and alkaline phosphatase is chiefly reacted in brush border. Electron microscopic investigation was performed on each material. Renal cell damage was mainly confined in the proximal renal tubules. Renal fine structure of one hours autolysis was composed of irregular disarrangement, swelling of microvilli, mitochondrial swelling with obscured cristae, dilated endoplsmic reticulum, vesicles and irregularity of the basal infoldings. The cell damage was more severe in three hour elapsed, the brush border was sloughed out or disarrangement disorderly and the cell membrane was often disrupted and lost thire cellular organelles. As a result of the enzymatic analysis, cellular functions were actively speculated in correlation to each organ configuration with chemical activities. Using this method, minimum change was discernible in spite of demostrating no cellular damage electron microscopically at time intervals.抄録全体を表示PDF形式でダウンロード (8533K) -

ジャーナル フリーCorrelationship between renogram, other sepasate renal functions (IVP, GFR, RPF, Fishberg test and urinary volume) and histological finding was studied on 11 cases after operation of staghorn calculi. Following finding were obtained.1) In the kidneys with the renogram of obstractive and delayed pattern, GFR, RPF and urinary volume were within normal limit. Fishberg test revealed low concentration. No remarkable change was noted in gross appearance of the kidneys. Histologically, hyalnization of the glomerulus and dilation of the tubulus, but with rare fibrosis and the alteriosclerosis were recognized. 2) In the kindeys presenting the renogram of non-functional pattern, GFR, RPF and Fishberg test were of low value. Excreation of urine was markedly reduced. These kidneys showed deformed contour on inspection. Histologically, in addition to hyaligation of the glomerulus and dilation of the tubulus, fibrosis and arteriosclerosis were observed. 3) Fishberg test revealed higher concentration on the contralateral kidney with standard pattern on renogram than diseased mate with delayed pattern. On the other hand, GFR and RPF value of the kidney with the standerd pattern on renogram was not always higher than those of the contralateral kidney with delayed pattern.抄録全体を表示PDF形式でダウンロード (4255K) -

ジャーナル フリーPlasma renin activity was significantly increased in anesthetized non-nephrectomized dogs after intravenous injection of the plasma obtained from bilateral nephrectomized dogs that had been made hypotension by controlled hemorrhage. However, plasma renin activity of anesthetized non-nephrectomized dogs was not increased after intravenous injection of the plasma which was collected from bilateral nephrectomized dogs without controlled hemorrhage. Renin activity was not detected in the nonhypotensive plasma and the hypotensive plasma from bilateral nephrectomized dogs. These results suggest an existence of renin releasing factor from extrarenal origin in the hypotensive dogs by the controlled hemorrhage, Although activity of renin releasing factor was not affected by dialysis with physiological saline, the activity was eliminated by heating under the condition of 100°C for 15 minutes. Renin releasing factor existed in the supernatant which was salted out in 75% ammonium sulfate from hypotensive plasma. By electrophoresis it moved with prealbumin fraction and by ultracentrifugation it was concentrated into the fraction of 4.16s prealbumins. From above mentioned evidences it may be concluded that the renin releasing factor plays an important role in renin release at the hypotensive state due to hemorrhage.抄録全体を表示PDF形式でダウンロード (1110K) -
