Pteridine Metabolism in the Skin of the Tadpole, Rana Catesbeiana.
The apparent structural similarity between purines and pteridines has been the subject of a number of studies attempting to demonstrate a relationship between these compounds in living systems. That a relationship does, in fact, exist has been shown, not only by purine incorporation into a pteridine (l-3), but also by the ability of at least one organism (Alcaligines fuecalis) to degrade a pter...
متن کاملEffect of stretch on contractility and ionic contents of the sartorius muscle of Rana pipiens.
KAPOPORT, STANLEY I., AND JEANNETTE M. BIDINGER. Eject of stretch on contractility and ionic contents of the sartorius muscle of Rana pipiens. Am. J. Physiol. 226(Z) : 452-457’ 1974.-When sartorius muscles of frogs are soaked in Ringer at room temperature, they gain Na, lose K, and lose contractility with time. These changes are retarded by stretching the muscles to ZO-30Y0 of their rest length...
متن کاملThe Epidermis of Rana Pipiens
The epidermis of adult Rana pipiens has been studied by electron microscopy and histological and histochemical methods. It was found that the epidermis is engaged in the production of both keratin and mucus. The basal cells are mainly filled with tonofilaments, whereas the cells located in the mid-portion of the epidermis contain both tonofilaments and mucous granules. Golgi vesicles and endopl...
متن کاملRenal handling of urea in Rana catesbeiana.
LONG, WILLIAM SCOTT. Renal handing of urea in Rana catesbeiana. Am. J. Physiol. 224(Z) : 482-490. 1973.-The processes involved in renal urea excretion in the bullfrog (Rana catesbeiana) were studied by clearance, tissue, and micropuncture methods. According to micropuncture data with urea-14C and inulin-3H, secretion of urea against a concentration gradient from plasma to tubular fluid occurs a...
متن کاملAcid exposure is an immune disruptor in adult Rana pipiens.
Acidic environments are physiological stressors for amphibians. The objective of the present study was to document the effect of an acidic environment on innate immune system function under controlled experimental conditions in Rana pipiens. We developed an in vivo assay, by injecting a suspension of 1-microm fluorescent beads in fluid thioglycollate, to induce peritonitis. The number of perito...
