Abstract

This study was to see if pregnant rats fed a pantothenic acid(PA) deficient diet for whole 3 weeks gestation would produce pups comparable to the normal controls, at the cost of maternal tissue PA concentration ([PA]) or coenzyme A content ([Co A]). Compared to the controls, dams fed a PA deficient diet tended to decrease weight gain, and produced pups with lower body, liver and brain weight (p<0.05). Postpartum dam's blood [PA] decreased more in PA deficient group than control (p<0.05, PA deficient : 2.52$\pm$0.66 to 0.77$\pm$0.23uM, control : 2.58$\pm$0.52 to 1.45$\pm$0.68uM), although Hb concentration did not differ between two groups. Pup's blood [PA] at birth was lower in PA deficient group than control group(1.75$\pm$0.27uM vs. 3.90$\pm$0.76uM, respectively, p<0.05) and 2-3 times that of postpartum dams in both two groups. [Co A] and [PA] in pup's tissues were 23-68% of dams in both groups, in spite of the higher [PA] in pups. These data suggest that Co A metabolism differs between pups and dams ; the pups were more adversely affected than dams by the dietary PA deficiency of dams during gestation.
