Abstract
The effects of bifemelane [4-(o-benzylphenoxy)-N-methylbutylamine hydrochloride] on the deposition of calcium and magnesium in central nervous system (CNS) tissues, heart, liver, kidney, muscle, abdominal aorta and bones were studied in rats maintained on standard and low-calcium diets. Rats were maintained for 90 days on the following diets: standard calcium (12.5 g/kg diet); standard with 100 mg/kg bifemelane; low-calcium (30 mg/kg diet); and low-calcium with bifemelane. The presence of bifemelane did not affect blood chemistry, but the magnesium concentration in the cerebellum was significantly (P less than 0.05) higher in rats receiving standard diet after bifemelane treatment. Magnesium concentrations in the pons, cerebellum, spinal cord, heart, liver and femur of bifemelane-treated rats fed low-calcium diets were significantly (P less than 0.05) higher compared with the corresponding controls, whereas the calcium concentration in the liver was significantly (P less than 0.05) lower. In general, bifemelane tended to decrease calcium deposition in the CNS and soft tissues of rats fed standard or low-calcium diets. Bifemelane may activate cerebral metabolism and maintain magnesium concentrations in the CNS and soft tissues, and be implicated in metal metabolism in rats fed low-calcium diets.
