The hepatoprotective activity of kolaviron (KV), a biflavonoid complex from Garcinia kola seeds, and its purified fractions was investigated in mice intoxicated with carbon tetrachloride (CCl4). The ability of vitamin E to attenuate the toxicity was also examined. KV was extracted from powdered seeds of G. kola and then separated by thin-layer chromatography into three fractions—Fraction I (FI), Fraction II (FII), and Fraction III (FIII), with ratio of fronts values of 0.48, 0.71, and 0.76, respectively. Pretreatment with KV, FI, and FII at a dose of 100 mg/kg of body weight for 2 weeks and then challenge with CCl4 at a dose of 1.2 g/kg of body weight, three times a week for 2 consecutive weeks, decreased the CCl4-induced increase in activities of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) by 31%, 30%, and 31% and 41%, 55%, and 42%, respectively. CCl4 intoxication also caused a significant (P < .05) accumulation of lipid peroxidation (LPO) products as revealed by the formation of the thiobarbituric acid-reactive substances: CCl4 induced LPO levels in serum and microsomes by 112% and 89%, respectively. However, pretreatment with KV, FI, and FII decreased LPO levels in serum by 31%, 41%, and 40% and in microsomes by 48%, 39%, and 35%, respectively. Vitamin E was protective in reducing the CCl4-induced increase in levels of AST, ALT, and γ-glutamyl transferase as well as LPO. Furthermore, CCl4 intoxication significantly (P < .05) decreased the activities of microsomal glucose-6-phosphatase, aniline hydroxylase, and cytosolic glutathione-S-transferase (GST). While pretreatments with KV, FI, and FII were able to ameliorate the levels of glucose-6-phosphatase and GST, there were no significant (P > .05) effects on the levels of aniline hydroxylase and DT-diaphorase. This study confirms that FI and FII from KV enhanced recovery from CCl4-induced hepatotoxicity by decreasing the extent of LPO and also inducing the levels of phase II enzyme (GST). These fractions are responsible for the observed antihepatotoxic effect of KV.

Sexing of birds at early age is very important for efficient selection and breeding; while characterization and taxonomic identification is relevant in conservation of birds’ genetic resources. This study used the genomic DNA of ten (10) guinea fowl keets to determine their sex using agarose gel electrophoresis and sequencing with chromo helicase DNA (CHD) binding genes, they were also characterize taxonomically using 12S rRNA mitochondria genes. The results of this study shows a double band (ZW) for females and a single band (W) for males under Agarose gel electrophoresis view, the Guinea fowl keets sequenced showed some deletions and were closer to Gallus_CHD12 in the phylogenetic tree. The Taxonomic classification result shows that the sequenced guineafowl keets were most related to the Numida meleagris 12S mitochondrial ribosomal RNA. This study corroborate the fact sex of guineafowl keet can be easily identified at genomic DNA level and they can be characterized taxonomically using the 12SrRNA mitochondrial genes.
