The Role of Aciduria in the Development of Hemoglobinuric Nephrosis in Dehydrated Rabbits
نویسندگان
چکیده
The effect of acid diets, fasting, and dehydration on the urine pH and the kidneys was determined in 11 control animals. Hyaline casts in the collecting tubules and interstitial medullary edema were observed in the 8 that survived. The test rabbits were subjected to the same treatment as the controls but, in addition, received 1.8 gm./kilo of intravenous homologous hemoglobin. Eleven of 18 animals died of hemoglobinuric nephrosis. The rabbits which died of hemoglobinuric nephrosis exhibited significant alterations in two or more of the following: kidney weight, pigment cast accumulation, and elevations of NPN. The theories which have been advanced to explain the pathogenesis of hemoglobinuric nephrosis are evaluated in the light of the present observations. It is proposed on the basis of them that antecedent tubular damage is of primary importance in the pathogenesis of hemoglobinuric nephrosis.

The Influence of Available Fluid on the Production of Experimental Hemoglobinuric Nephrosis in Rabbits
The importance of previous dehydration on the production of hemoglobinuric nephrosis is substantiated. Hemoglobinuric nephrosis regularly occurred in rabbits 3 to 16 days following the injections of hemoglobin. Five of 15 animals died of fatal hemoglobinuric nephrosis; the combined kidney weight in these exceeded the weight of the kidneys of control rabbits and of those which survived. Addition...

The endothelial permeability of aorta (EPA) is influenced by atherosclerosis. Whether the physiological difference in EPA is a sex-dependent phenomenon remains to be determined. The objective of this study was to determine the EPA difference between male and female rabbits. An experimental model was designed to obtain 4 groups of animals.
