The effects of inanition and The effects of inanition and malnutrition upon growth and structure effectsofinaniti00jack Year: 1925 EFFECTS ON THE URINARY TRACT 387 scurvy, Hojer ('24) found renal atrophy, often combined with necrosis and certain peculiar calcareous deposits. In aqueous inanition (thirst), Schuchardt ('47) found a loss of 25 per cent in the weight of the kidneys in pigeons on dry barley diet, with loss of 34 per cent in body weight. In a dog on dry diet with loss of per cent in body weight, Falck and Scheffer ('54) noted an apparent loss of only per cent in the kid- neys and ureter, but a loss of per cent in the urinary bladder. In dogs on dry food, Bowin ('80) found the epithelium of the renal tubules somewhat atrophic and cloudy. In a dog on dry diet with loss of 24 per cent in body weight, Pernice and Scagliosi ('95a) found the kidneys apparently normal in size, hyperemic, and with slightly nodulated external surface. The relation of cortex and medulla appeared normal. Microscopically the renal epithelial cells showed cloudy swelling and indistinct nuclei; some cells containing fine fatty granules. In places, the capsule space was filled with blood, compressing the glomerulus. FlG. 99.—Portion of a section of the kidney from a young fowl on aqueous inanition (dry diet), ft, uriniferous tubules containing epithelial cells with 'fatty degeneration;' gc, urinif- erous tubule containing a granular cylinder; gl, an abnormal renal (Malpighian) corpuscle, showing capsule and glomerulus (glomerulitis?); re, stroma, with small round cell infiltration. X400. (Pernice and Scagliosi '95a.) Many uriniferous tubules were also filled with blood, and some contained hyalin cylinders. In many glomeruli the vascular endothelium appeared greatly proliferated; sometimes the capillary loops had lost their nuclei. Osmic preparations showed marked fatty degeneration in many glomeruli. Small round cell infiltration occurred around some of the glomeruli
