[The effects of arginine and growth hormone on the nitrogen balance of rats]. / Effets de l'arginine et de l'hormone de croissance sur le bilan d'azote du rat

ABSTRACT

Intramuscular administration effects of arginine aspartate (AA 0,50 g a day for 4 days), arginine chlorhydrate (CA 0.34 g a day for 4 days), potassium aspartate (AK 0.22 g a day for 4 days) with equal arginine base and aspartate ion supply for all products, bovine growth hormone (STH 2 U.I. a day for 4 days), and the association of these substances, are studied on 6 rats, during a 74 days nitrogen balance period. Arginine (endogenous STH secretion stimulation) produces a greater nitrogen retention with AA (+ 184%, p less than 0.01) than CA (+ 71% p less than 0.10). A.K. had no effect. With exogenous STH, effect is important (+ 248%, p less than 0.01) but does not significantly differ from AA. STH + A.A. and STH + C.A. associations (exogenous and endogenous STH) produce a very marked nitrogen retention (+ 282% and + 252%, p less than 0.01) which, however, does not significantly differ from STH when given alone.
