Changes of Expression of Intermediate Filament Proteins During Ontogenesis of Eccrine Sweat Glands

Secretion of eccrine sweat glands during exercise.

Metabolic studies of isolated human eccrine sweat glands.

This paper describes a method for isolating and studying the metabolism of human eccrine sweat glands. (a) Electron microscopy of glands which had been isolated and then incubated for an hour revealed no apparent alteration in morphology. (b) Known variation in gland size (male > female > children) was reflected in the relative rates of lactate production. (c) Lactate production was approximate...

The Ultrastructure and Histophysiology of Human Eccrine Sweat Glands

The electron microscopy of human eccrine sweat glands has been studied before and after stimulation by pilocarpine iontophoresis. The identity of the dark and clear cells in the secretory segment as defined by Montagna et al. (23) was determined by studying serial sections, thin for electron microscopy and thick for light microscopy. Cells with numerous apical secretory vacuoles are termed muco...

Expression of thick filament proteins during ontogenesis of the mussel Mytilus trossulus (Mollusca: Bivalvia).

The appearance of thick filament proteins organized into supramolecular complexes was studied by SDS-PAGE and Western-blot analysis at different developmental stages of the mussel Mytilus trossulus. Paramyosin appeared at the egg stage, while twitchin and myorod appeared at the blastula stage (12 h after fertilization). In addition, RT-PCR analysis showed that the twitchin genes were expressed ...

Function of human eccrine sweat glands during dynamic exercise and passive heat stress.

The purpose of this study was to identify the pattern of change in the density of activated sweat glands (ASG) and sweat output per gland (SGO) during dynamic constant-workload exercise and passive heat stress. Eight male subjects (22.8 +/- 0.9 yr) exercised at a constant workload (117.5 +/- 4.8 W) and were also passively heated by lower-leg immersion into hot water of 42 degrees C under an amb...
