[Infusion therapy in newborn calves with diarrhea from the area of Ankara with special reference to acidosis (part 1)].

Characteristic changes (hyperkalemia, metabolic acidosis and azotemia) occurred in the blood of 54 calves 1 to 15 days old with diarrhoea. Clinical signs of dehydration were observed. Average values were: Potassium 6.

The occurrence of lipid droplets in the proximal and distal tubules of the rat kidney after folic acid treatment.

Folic acid in high doses gives rise to an accumulation of lipid droplets in the kidney in addition to other changes in the epithelial of both proximal and distal tubules. With the administration of methionine a decrease of lipid droplets and an improvement of the structures of most of the membranes and mitochrondria are observed. These findings have been discussed in regard to the theory of the "chemically induced hyperplasia of the kidneys" related to folic acid.

Electronmicroscopical investigations of the effects of heparin upon the structural elements of the rat glomerulus.

In this study the ultrastructure of the renal glomeruli was investigated 30 minutes after the intraperitoneal administration of heparin. It was observed that the matrix and fibrillary structure became more abundant in the mesangial cells and also in the epicytes; it was noted that the Golgi apparatus was active and the granular endoplasmic reticulum was very enlarged, partially containing structures of a particular shape. Furthermore, there was a general thickening and a dense accumulation of matter in the basement membrane.
