Heat shock induced ultrastructural alterations in Stylonychia mytilus cells.

Fine structural observations on heat shocked cells of S. mytilus reveal that cell organelles undergo structural alterations. Mitochondria show distorted shapes with disorganized cristae and vacuolar spaces. Pulse heat shock results in dilated rough endoplasmic reticulum, abundant polysomes as well as smooth endoplasmic reticulum. Heat shocked cells show membrane bound bodies containing osmiophi...

Ultrastructural alterations induced by lithium chloride in DNA-containing organelles of a bat trypanosome.

Ultrastructural alterations in rabbit taste buds induced by prolonged treatment with cycloheximide.

Prolonged administration of cycloheximide, an inhibitor of ribosomal protein synthesis, induces degeneration of rabbit taste bud cells: the degenerative changes resemble early changes in denervated taste buds. Our observations show that the pattern of degeneration is quite different in the three cell types of the taste buds. The earliest changes in type II and III cells are an increase in cytop...

Ultrastructural alterations in the dog brain after profound hypothermia induced by extracorporeal circuit.

Ullraslruclural Alterations in the Dog Brain After Profound Hypothermia Induced by Extracorporeal Circuit • This study has demonstrated that hypothermia with or without circulatory arrest produced ultrastructural alterations in the dog brain. Fluid accumulation in the perivascular area and in the neuropil persists for at least seven days. Neurons in all areas of the brain studied are quite resi...
