The Effects of Chlormequat Chloride on the Development of Pubertal Male Rats
In this study, CCC was administered to rats daily by gavage on postnatal days 23-60 at doses of 0, 75, 150 and 300mg/kg bw/d. The results showed that body weight and the length of the right femur were significantly decreased in the 300mg/kg bw/d group. Histological analysis of proximal growth plates of the right femurs showed narrowed proliferative zones and hypertrophic zones in CCC-treated groups. The mRNA expression of growth hormone, growth hormone receptor and insulin like growth factor 1 were decreased in the CCC-treated group. The results indicated that CCC may affect the expression of growth hormone and insulin-like growth factor 1 and subsequently cause a decrease in body weight and bone length. Graphical abstract
