acid-phosphatase and Dehydration

Adrenocortical responses to diverse stressful situations (dehydration, formaldehyde treatment and salt loading) were studied in the adult female soft-shelled turtle, Lissenmys p. punctata. Dehydration, formaldehyde treatment (formalin, 1%: 0.1 ml/100 g body weight daily) or salt loading (NaCl, 1%: 0.1 ml/100 g body weight daily) treatments consecutively for 7 days caused hypertrophy of the adrenocortical cells with their nuclear diameter increased, and depletions of adrenal cholesterol and ascorbic acid concentrations followed by decreased acid phosphatase and alkaline phosphatase activities in turtles. Corticosterone levels were elevated in both the adrenal gland and serum of turtles after dehydration and formalin stress, but the hormone level remained unaltered after salt loading in turtles. The results suggest active involvement of adrenal cortex in stress for homeostasis in Lissemys turtles.

An increased stability of liver lysosomes and mitochondria of burned, dehydrated and tumour-bearing rats has been found in the present investigations. Using biochemical criteria we were able to show that the membranes of liver subcellular particles of these animals become more resistent to the labilizing action of CCl4. The latter effect was confirmed by electron microscopic data. The tumour growth, dehydration and burning of rats as well as sleep deprivation, overheating, lanthanum and ruthenium red have been shown to cause changes in the activity of some enzyme-systems located in endoplasmic reticulum. The protective action of these chemical, pathological and stress factors against CCl4 produced damage to the cell organelles studied is discussed in relation to the activity of the drug metabolizing pathways; biochemical (modifying of some enzyme activity) as well as pharmacological (duration of hexobarbital sleep) data were used as criteria for the activity of these pathways.
