Chick Spinal Cord

Soluble fractions of homogenized skeletal muscle were found to promote neuronal migration and neuritic and glial outgrowth from embryonic chick spinal cord explants. Fractions obtained from skeletal muscle immobilized by prolonged treatment with curare were significantly more effective than normal muscle in accelerating neuronal and glial development. Fractions from other tissues such as brain and lung did not enhance neuronal differentiation, but were effective in stimulating outgrowth of glial cells. Separate measurements of glial and neuronal responses indicate that tissue fractions produce independent effects on the glial and neuronal components.

Histochemical Changes

ABSTRACT Acute changes in glucose-6-phosphate dehydrogenase and isocitrate dehydrogenase activity in the zona glomerulosa of the rat adrenal cortex were induced by peritoneal dialysis with 5 % glucose. Although less clear, the activity of 3β-ol-hydroxysteroid dehydrogenase also seemed to increase as well. No changes were seen in the activity of succinate dehydrogenase. Dialysis with 0.9 % NaCl had no effect on any of the enzymes investigated. The possible significance of these observations is discussed.
