GOLGI APPARATUS, GERL, AND LYSOSOMES OF NEURONS IN RAT DORSAL ROOT GANGLIA, STUDIED BY THICK SECTION AND THIN SECTION CYTOCHEMISTRY
TLDR
Serial 0.5-µ and thin sections of thiamine pyrophosphatase-incubated material demonstrate that, in the neurons studied, the Golgi apparatus is a continuous network coursing through the cytoplasm, and suggest that GERL is also a continuous structure throughout the cy toplasm. Expand
The peroxisomes of human hepatocytes.
TLDR
It is concluded that various pathologic processes involving the hepatocytic cytoplasm exert different effects on peroxisomes, and a possible involvement of perxisomes ought to be considered whenever metabolic or pathologic process affect the liver. Expand
Morphologic and chemical studies on a murine mutation (toxic milk mice) resulting in hepatic copper toxicosis.
TLDR
Comparisons with other inherited mammalian disorders associated with hepatic copper toxicosis indicate that copper causes species specific organelle injury. Expand
STUDIES ON MICROPEROXISOMES II. A CYTOCHEMICAL METHOD FOR LIGHT AND ELECTRON MICROSCOPY
A modification of the Novikoff-Goldfischer alkaline 3,3'-diaminobenzidine medium for visualizing peroxisomes is described. It makes possible light microscopic as well as electron microscopic studies… Expand
GOLGI APPARATUS AND LYSOSOMES.
DIFFUSION ARTIFACTS IN 3,3'-DIAMINOBENZIDINE CYTOCHEMISTRY
TLDR
The results indicate that fixation, dehydration and embedding employed do not disturb the antigen-antibody reaction, and GMA sect ions gave clearer localization of the antigen and antibody at both the cytologic and histologic level than frozen or paraffin sections. Expand
NUCLEOSIDE PHOSPHATASE AND CHOLINESTERASE ACTIVITIES IN DORSAL ROOT GANGLIA AND PERIPHERAL NERVE
TLDR
It is considered likely that diffusion artifacts account for the nucleoside phosphatase reaction product frequently found along the outer surfaces of myelinated fibers and within vacuoles at the Schwann cell surfaces of these fibers. Expand
Studies of the secretory process in the mammalian exocrine pancreas. I. The condensing vacuoles
TLDR
Phosphatase cytochemistry was used to distinguish between the Golgi apparatus and GERL in pancreatic exocrine cells of guinea pig, rat, rabbit, and hamster, and it is proposed that some secretory components may have direct access to the condensing vacuoles from ER. Expand
STUDIES ON MICROPEROXISOMES V. ARE MICROPEROXISOMES UBIQUITOUS IN MAMMALIAN CELLS?
TLDR
A variety of mammalian cell types has been studied by electron microscopy following incubation in a 3,3'-diaminobenzidine medium and it is presumed that molecular interchange occurs between these two organelles. Expand
