Lead is a multisystemic toxicant when it accumulates and is hazardous to health. This study was conducted to determine the effect of Caulerpa lentillifera aqueous extract on lead accumulation in the internal organs and liver functions of lead-intoxicated rats. Sprague Dawley rats (n = 24) were divided into four groups (n = 6). Group I was healthy rats treated with saline (2 ml/kg bwt) daily for 28 days. Group II was healthy rats treated with C. lentillifera aqueous extract (500 mg/kg bwt) daily for 28 days. Group III was intoxicated with lead acetate (20 mg/kg bwt) daily for 4 days and then treated with saline (2 ml/kg bwt) for another 24 days. Group IV was intoxicated with lead acetate (20 mg/kg bwt) daily for 4 days and then treated with C. lentillifera aqueous extract (500 mg/kg bwt) for another 24 days. Lead accumulation in the internal organs was measured by the atomic absorption spectrophotometer and the liver function markers were determined using assay kits. Lead intoxication s.....

The application of biopesticides is progressively encouraged for its advantages associated with environmental safety and high biodegradability. The objectives of this study were to compare the phytochemical constituents, anti-feedant, and molluscicidal activities of spices against the giant African land snail, Achatina fulica. The spices evaluated were clove (Syzygium aromaticum), cinnamon (Cinnamomum verum), black pepper (Piper nigrum), cumin (Cuminum cyminum) and coriander (Coriandrum sativum). Phytochemical constituents of spices were screened by qualitative standard protocols. Anti-feedant activity was investigated by the leaf disc no-choice bioassay method and molluscicidal activity was evaluated by a 72-h contact toxicity test. The phytochemical screening showed positive results for tannins, saponins, alkaloids, flavonoids, terpenoids, and phenols in clove, cinnamon, cumin and coriander ethanolic extracts whereas only tannins, alkaloids and terpenoids were found in the black pepp.....
