摘要：Acute toxicity of arsenic to Tilapia (Oreochromis mossambicus) and tissue repairing activity of Glycosmis pentaphylla leaf extract and its histological impacts on gill, liver, and kidney tissues were evaluated. Fish were divided into six groups viz. control, group 1, group 2, group 3, group 4, and group 5. 4.87 ppm of NaAsO2 was administrated in group 1, group 3, and group 5. In group 3, after arsenic exposure, 2.5 g of leaf extract of Glycosmis pentaphylla per kg of fish food was added. In group 5, 5g of G. pentaphylla leaf extract per kg of fish food was added. In group 2, 2.5 g of leaf extract per kg of fish food was added and in group 4, 5g leaf extract per kg of fish food was added. The control group showed normal histology of the gill, liver, and kidney. The histological observations revealed the tissue repairing activities in group 2 fish’s gill, liver, and kidney. These results revealed the protective and tissue repairing potential of G. pentaphylla as a feed supplement against NaAsO2 induced toxicity.
