Influence of an inhibitor of monoaminooxidase (nialamide) on the absorption and retention of nitrogen in adult rats

A study was made on adult rats (170 g) of the effect of nialamide (20 mg/100 g of diet), an inhibitor of monoaminooxidase, administered for 15 or 30 days (short or long-term, respectively), with food intake controlled (pair fed), on the absorption and retention of nitrogen, and on the nitrogen content in the liver, the gastronemio and longissimus dorsi muscles and in the small intestine. Nialamide administered for a time which can be considered prolonged (30 days) negatively affects absorption of alimentary protein, while metabolic utilization is reduced when the drug is administered both in the short and the long term. Proteic catabolism is less marked in male rats, due to the hormonal anabolizant situation in this sex. Nitrogen content under the effect of nialamide showed no significant variation in the gastronemio muscle or in the small intestine. There is a clear reduction in the longissimus dorsi muscle and an increase in the liver of those animals of both sexes treated with the drug, with the exception of male rats given nialamide in the long term.

Comparative study of the influence of an inhibitor of monoaminooxidase (nialamide) on the calcium and phosphorus metabolism in slow and fast-growing rats

Nialamide was supplied to slow-growing animals in doses of 20 mg/100 g of diet for 15 or 30 days. The dose for fast-growing animals was 10 mg/100 g of diet. The digestive utilization of calcium and phosphorus decreases significantly when adult slow-growing rats receive the drug for 30 days. This fall is already important in fast-growing rats when they receive nialamide for only 15 days. In the same way the falls in the retention of calcium and phosphorus in adult rats are only evident when the period of treatment is through 30 days, even females being in negative balance of phosphorus. The amount of calcium retained decreases significantly in fast-growing rats and so does phosphorus impressively after only 15 days of treatment.
