Abstract Introduction: Histopathological effects of ethanol extract of Adenium obesum stem bark on the liver of Clariasgariepinus was investigated over a 96-h exposure period as an effective organic piscicide. Materials and Methods: An acute static toxicity bioassay was performed after a preliminary concentration range finding test was conducted. Results: Exposed fish showed adaptation behavioural changes with those of respiratory distress and abnormal nervous signs of toxicity, which was concentration-dependent. Mortality was recorded in some of the exposed fish while a median lethal concentration of 7.15 mgL-1 was established for the extract in the exposed fish. Non-significant (p>0.05) changes were recorded in serum aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase activities of the exposed ish. Moderate liver damage was observed in the exposed fish based on the degree of tissue change (DTC) grading where significant (p<0.05) differences were observed between the DTC of the exposed groups and the control. Conclusion: Ethanol extract of A. obesum stem bark was toxic to the exposed fish with evidence of hepatotoxicity and therefore, can be used to eradicate the hardy C.gariepinus from aquatic environments.

Background: Natural preservatives are compounds produced by natural ingredients that can suppress bacterial growth and development. Natural preservatives are carried out because most of the preservatives circulating are chemicals and unsafe for the body. One of the natural preservatives is by using garlic extract (Allium sativum L).  Objective: This study is aimed to determine the effectiveness of the antibacterial garlic (Allium sativum L) as a natural preservative in fresh African catfish (Clarias gariepinus).  Method: This research used the Pour Plate iroculation method. African catfish (Clarias gariepinus) which is soaked with garlic (Allium sativum L) with a concentration of 7%, 14% and 21% for 30 minutes, then the fish will be kept at room temperature with a storage period of 24 hours and 48 hours and calculated growth in bacterial numbers with the Colony counter.  Result: Based on the research result, it was found that garlic extract (Allium sativum L) can obstruct the effectiveness of antibacterial in African catfish (Clarias gariepinus) at a concentration of 14%.

Abstract Objective This study was aimed at evaluating the toxicity and the antioxidant property of Cassia fistula stem bark extracts in zebrafish. Materials and Methods Crude aqueous and ethanol extracts of C. fistula stem bark were obtained following a standard solvent-based extraction method. The toxicity of these extracts on zebrafish embryonic development was determined and the LC50 values were calculated. Finally, the antioxidant property of C. fistula stem bark extracts was determined in arsenic-induced oxidative stress models of zebrafish. Results The aqueous extract of C. fistula stem bark showed a slightly larger LC50 value (213.6 ppm) compared with the ethanol extract (LC50 = 63.5 ppm), suggesting a lower toxicity of the aqueous extract. A significant reduction of reactive oxygen species (ROS) signal was observed in arsenic-exposed embryos treated with the aqueous extract, but not the ethanol extract, indicating that the antioxidant activity is present only in the aqueous extract of C. fistula stem bark. Conclusion Identification of antioxidants from natural sources is desirable because of increasing safety concerns associated with synthetic antioxidants. This study demonstrated that aqueous extract from C. fistula stem bark possesses antioxidant properties, which can be further characterized for mechanism of action and potential applications.
