TL;DR: The metabolic modulations have been correlated towards the positive survival value of the fish in alkaline waters and mobilization of tissue free ammonia towards glutamine formation was suggested.
Abstract: Freshwater fishTilapia mossambica (Peters) were exposed to sublethal alkaline water (pH 9·0) and the branchial protein metabolism was studied on acute exposure and acclimation. Branchial tissue had elevated structural and soluble protein fractions on acclimation which was correlated towards the gill hypertrophy. Proteolytic activity of the tissue was elevated on both acute exposure and acclimation. A/O ratio which forms a measure of ammonia formed per unit O2 consumption was lesser on acclimation and hence mobilization of tissue free ammonia towards glutamine formation was suggested. The metabolic modulations have been correlated towards the positive survival value of the fish in alkaline waters.

TL;DR: Tissue oxidative metabolism was also correlated with regulation of activities of enzymes concerned with anaerobic pathways and increased glycogenolysis and glycolysis was suggested to be due to stepped-up glycogenesis.
Abstract: Electrical stimulations were applied to the gastrocnemius muscle of intact frog. Rana hexadactyla (Lesson) for short-term (SMS) and prolonged (PMS) periods. Short-term muscular stimulations resulted in decreased glycogenolysis and glycolysis with depleted glycogen and lactic acid contents in the muscles and increased lactic acid content in the blood. The activity levels of SDH and MDH were decreased in SMS muscles. Prolonged muscular stimulations, on the other hand, increased glycogenolysis and glycogenolysis was suggested to be due to stepped-up glycogenesis. Tissue oxidative metabolism was also correlated with regulation of activities of enzymes concerned with anaerobic pathways.

TL;DR: The phospholipid content of epididymis was significantly depleted, while the same was elevated in non-reproductive tissues, and the levels of triglycerides and cholesterol were elevated in all the tissues of orchiectomized rats.
Abstract: Bilateral orchiectomy has been performed in adult albino rats and tissue lipid profiles were compared with the controls. Both the reproductive and non-reproductive tissues and serum accumulated lipid with suppressed lipolysis on orchiectomy. The levels of triglycerides and cholesterol were elevated in all the tissues of orchiectomized rats. The phospholipid content of epididymis was significantly depleted, while the same was elevated in non-reproductive tissues.
