A simple and rapid quantification method was developed for determining nisoldipine in plasma. After a simple protein precipitation with a mixture of 10% of zinc sulfate and methanol, the analytes were chromatographed on a reversed-phase C(18) column, and detected by MS/MS. The assay precision was less than 10.7%, and the accuracy ranged from 86 to 112%. The limit of quantification was 0.1 ng/ml...

Although rhesus monkeys have been generally regarded as refractory to infection with poliomyelitis virus administered by the oral route, two of seven infant rhesus developed paralytic poliomyelitis when fed murine-adapted strains of virus. Preliminary intranasal treatment with zinc sulfate and negative serial sections of the olfactory bulbs of the positive animals ruled out the possibility that...

Zinc deficiency has detrimental effects on child health and increases mortality rate of pneumonia and gastroenteritis. By improving absorptive function of villous cells and by reducing pathogenic enterobacteriaceae in lumen, Zinc improves diarrhea outcome in children. Previous studies in developing ...

Chronic hyperglycemia in diabetes is a major causative factor of free radical generation which further leads to many secondary diabetic complications via the damage to cellular proteins, membrane lipids, and nucleic acids. Zinc is an essential trace element in all living systems and plays a structural role in many proteins and enzymes. Somatostatin is known to have inhibitory effects on various...
