摘要: Effects of in vivo exposure with fenvalerate, esfenvalerate andDDT on hepatic gap junctional intercellular communication (GJIC) Sprague-Dawley (SD) rats were examined by vivolin vitro dye-transfer assay and immunohistochemical staining connexin 32 (C×32, major liver junction protein). Fenvalerate (75 mg/kg/day), (25 DDT (50 mg/kg/day) corn oil (vehicle control, 5mllkglday) administered orally once a day. Animals killed at weeks 1, 2, 4 6 after starting the experiment. In fenvalerate- esfenvalerate-groups, no compound-related changes GJIC C×32 expression observed. On contrary, DDT-group, average sizes dye spread injection Lucifer Yellow decreased 2 4, area per GJ spot shown C×32-immunohistochemical 6. It is concluded that neither fenvalerate nor inhibits exposure.
