Tissue obtained by punch biopsy from the antebrachial organ of
Lemur catta has been studied with the electron microscope. This study
describes the fine structure of the interstitial cells found between
apocrine sweat glands in the antebrachial organ. These large polygonal
cells are of three types: light cells, dark cells,...
A comparative study was made of the morphology and histology of
three major groups of light organs in the genus Lampanyctus of the
family Myctophidae for the species, L. leucopsarus, L. ritteri,
L. nannochir, and L. regalis. The species can be divided according
to their ranges in depth, the first...
The distributions of alkaline phosphatase, acid phosphatase,
non-specific esterases, and glycogen were described for the antennal
glands of the freshwater crayfish, Pacifastacus, and the marine crabs
Cancer and Pugettia.
Alkaline phosphatase is confined primarily to the luminal edge
of the labyrinth in all of the above forms whereas acid phosphatase...
Part of the Y chromosome in humans is detectable as a brightly
fluorescing body in interphase nuclei stained with quinacrine dyes.
This fluorescent body when stained with quinacrine mustard dihydrochloride,
in cells from some 15 human subjects, was seen to manifest
a variable morphology which appeared to be related to...
The energy strategies of early development of the Pacific Oyster,
Crassostrea gigas, were examined. Changes in proteins, total carbohydrates,
free reducing sugars and total and neutral lipids were
determined for the unfertilized egg and larval stages through 13 days
post-settlement.
During early larval stages neutral lipid levels decreased and
provided...
Electron microscopic, histochemical and thin-layer chromatographic
techniques have been used to study some cytological changes
associated with seasonal lipid deposition in the liver of Ascaphus.
Histochemical and chromatographic information has shown that unsaturated triglycerides occur in great quantities in the liver of pre-ovulatory females and may serve as a solvent...
Primary monolayer cultures of chick renal epithelial cells
grown on plastic coverslips were reversibly dissociated with the
chelating agent ethylenediaminetetraacetic acid (EDTA). The cellular
responses during dissociation and reaggregation in Hank's balanced
salt solution (BSS) were observed with phase optics and recorded
by time-lapse cinemicrography.
The epithelial cells grow as...
