,約具

26 ~ 50%

程度的組織病理變化,其餘不含菲克利農

藥之試驗組則無此病變,顯示該病變為菲

克利農藥特異性之肝毒性表現,但含菲克

利農藥之各試驗組其肝細胞空泡化脂肪變

性表現程度上並無差異,各試驗組肝組織

病理病變詳如圖五所示。

五、油紅染色結果:除含菲克利農藥之

各試驗組與空白對照組相較為陽性結果外,

陽性程度均為中度,積分為

圖二、試驗農藥對各試驗組血清中

ALT

酵素影響結果。

Effects of chlorothalonil, hexaconazole and imidacloprid on serum ALT levels in rats.

B: Blank, C: Chlorothalonil (200 mg/kg), H: Hexaconazole (150 mg/kg), I: Imidacloprid (75 mg/kg). Means with

different letters (shown above bars) are significantly different at a level of

P

< 0.05 according to Fisher

s LSD test.
