OBJECTIVE To characterize PCB 153 action on the ovary, the direct effect of PCB153 was investigated in vitro using a co-culture of pig granulosa and theca cells collected during different stages of follicular development. METHODS The cells were cultured in the absence or presence of 5, 10, 50 or 100 ng/ml of PCB 153. Media were changed after 48, 96 and(More)
OBJECTIVE Polybrominated diphenyl ethers (PBDEs) are used as flame retardants in a wide variety of products. They show an accumulation pattern similar to that of well-known persistent organic pollutants (POPs) such as polychlorinated biphenyls (PCBs), DDT and others. So far, most of information showing adverse effects of various POPs was based on the(More)
We studied functional and morphological luteinization of granulosa cells in intact preovulatory follicles and in cultured granulosa cells collected from the proestrous follicles of the rat. Steroid hormones were measured by radioimmunoassay in follicles dissected from the ovaries every 2 hrs on the day of proestrus beginning at 8 : 00 hrs and terminating at(More)
