Biochemical Studies on Rabbits Treated With Novel Pyridine and Dihydropyridine Derivatives and Vitamin E

Groups of adult male frogs were force fed on diets either devoid of fat and tocopherols or containing "stripped" corn oil with or without added α-tocopherol for 120 days. At the end of this period histological examinations of the gastrocnemius muscles and testes revealed no signs of degeneration in any dietary group. Biochemical studies on the muscle gave no reflection of tocopherol deficiency in the levels or proportions of total ribonucleic acid and deoxyribonucleic acid but did show a marked lowering of total muscle creatine in frogs on the tocopherol-free diets. The deficient animals subjected to considerable amounts of the polyunsaturated corn oil exhibited the lowest creatine levels. It is concluded that the adult frog has a dietary requirement for vitamin E and that more prolonged deprivation probably would result in the dystrophic symptoms commonly noted in other species.

Extracellular Materials

Ruthenium red has been used as a stain to demonstrate a variety of extracellular materials, especially acid mucopolysaccharides. It also reacts with certain intracellular and extracellular lipids. Since biochemical studies in our laboratory demonstrated the presence of a variety of monosaccharides in human hair ruthenium red staining procedures were adopted in order to evaluate the presence and morphological location of acid oligosaccharides in the keratinized aspect of hair.

And Control

Hypophysectomy of the rat renders this animal deficient in the hormones of the anterior pituitary gland, thus causing many primary and secondary hormonal effects on basic liver functions. Biochemical studies of these alterations in the rat liver cell are quite extensive; however, relatively few morphological observations on such cells have been recorded. Because the available biochemical information was derived mostly from disrupted and fractionated liver cells, it seemed desirable to examine the problem with the techniques of electron microscopy in order to see what changes are apparent in the intact liver cell after hypophysectomy. Accordingly, liver cells from rats which had been hypophysectomized 5-120 days before sacrifice were studied. Sham-operated rats served as controls and both hypophysectomized and control rats were fasted 15 hours before sacrifice.
