Abstract


This study aimed to investigate the toxicity of raw and boiled tissue extracts of Lagocephalus lagocephalus flesh or liver. Five groups of six male Wistar rats each were used. Four groups received a daily intraperitoneal injection of raw or boiled tissue extracts of L. lagocephalus flesh and liver at a dose of 1 ml/100 g (v/w). The fifth group served as a sham and received a daily intraperitoneal injection of saline solution (1 ml/100 g of 0.9% NaCl, v/w). During the experiment, there was a slight decrease in body weight in all treated groups. Our results revealed that the activities of various enzymes like transaminase, alkaline phosphatase (ALP), gamma glutamyl transpeptidase (γ-GT) and lactate dehydrogenase (LDH) decreased in serum and increased in liver and kidney tissues, producing hepatotoxicity and nephrotoxicity in the treated rats. These observations on the toxicity of this Tunisian puffer fish revealing toxicity especially in the flesh, the edible part of fish, clearly indicate the danger of using this fish as food.

Key words: Hepatotoxicity, Lagocephalus lagocephalus, nephrotoxicity.
