Abstract:

This study has the aim of verifying the

histological alterations in the hepatic tissue of Rana

ridibunda when exposed to 0.4mg/g body weight of

Actara 25WG at 4-6ÂșC, respectively at 22-24ÂșC. The

toxic was administrated with intraperitoneal shots

(one shot every two days, in a scheme of three

weeks).

A technique of light microscopy was used. At

the end of the experiment. we have observed the

presence of biliary pigment in the citosol. Some

hepatocytes lost cellular contour.

Karyomegalia and polyploidy together with

accumulation of infiltrates were also observed. A

large zone of fibrosis was present between

hepatocytes and around blood vessels. The

histological changes were more powerful at 22-24ÂșC.

Keywords:

frog, thiamethoxame, liver, karyomegalia, accumulation of infiltrates, fibrosis.
