alterations in connective tissue and intestine produced by hypervitaminosis a in xenopus laevis. 196114005936
changes in connective tissue and intestine caused by vitamin a in amphibia, and their acceleration by hydrocortisone.in view of the theory that an excess of vitamin a causes release of cathepsins from intracellular lysosomes, hypervitaminosis a was induced orally in the larvae of xenopus laevis. it was predicted that the tails of these amphibia would undergo resorption prior to metamorphosis, since the presence of abundant lysosomes, associated with measurable increases of catheptic activity, had previously been demonstrated in the resorbing tails of amphibia during metamorphosis. this prediction was confirmed ...196119867204

the structure of myelin sheaths in the central nervous system of xenopus laevis (daudin).the structure of myelinated nerve fibres has been studied in the spinal cord and optic nerve of the tadpoles of xenopus laevis. potassium permanganate-fixed material was examined with the electron microscope. the myelin sheath itself is made up of spirally arranged lamellae in which the intraperiod and dense lines alternate. inside the myelin sheath an inner cytoplasmic process surrounds the axon and where the external surfaces of its bounding membrane come together an internal mesaxon is formed ...196014432183

the formation and structure of myelin sheaths in the central nervous system.the development and structure of myelin sheaths have been studied in the optic nerves of rats and of xenopus laevis tadpoles. both potassium permanganate- and osmium-fixed material was examined with the electron microscope. in the first stage of myelinogenesis the nerve fibre is surrounded by a cell process which envelops it and forms a mesaxon. the mesaxon then elongates into a loose spiral from which the cytoplasm is later excluded, so that compact myelin is formed. this process is similar to ...196013734758
