The leaves of Madhuca (M.) indica J.f.Gmel. (Sapotaceae) have been used traditionally in folk medicine due to its astringent properties and are effective in treatment of eczema and snake bites. Methanolic extract of M. indica is rich in tannins and has been proven experimentally to possess antibacterial activity. The present study was undertaken to evaluate the anti-ulcer and antioxidant activity of M. indica in rats. The methanolic extract of leaves of M. indica was tested at various doses (75, 150 and 300 mg/kg, p.o.) for its effect on gastric secretion and gastric ulcers in pylorus-ligation and on ethanol- induced gastric mucosal injury in rats. The significant reduction in ulcer index in both the models along with an increase in the pH of the gastric fluid and mucin content of stomach, and the acid secretory parameters such as total acidity and volume of gastric fluid were also significantly reduced along with reduction in the pepsin activity in pylorus-ligated rats proved the anti-ulcer activity of M. indica. The increase in the levels of superoxide dismutase, catalase and reduced glutathione and decrease in lipid peroxidation in both the models proved the antioxidant activity of M. indica. Thus it can be concluded that M. indica possesses anti-ulcer activity, which can be attributed to its antioxidant mechanism of action.

Objective: This study was conducted to identify and evaluate the effective single nucleotide polymorphism (SNP) markers for fat deposition in the longissimus dorsi muscles of pigs using the amplified fragment length polymorphism (AFLP) approach. Methods: Sixty-four selective primer combinations were used to identify the AFLP markers in the 20 highest- and 20 lowest-intramuscular fat (IMF) content phenotypes. Five AFLP fragments were converted into simple codominant SNP markers. These SNP markers were tested in terms of their association with IMF content and fatty acid (FA) composition traits in 620 commercially crossbred pigs. Results: The SSC7 g.4937240C>G marker showed an association with IMF content (p<0.05). The SSC9 g.5496647_5496662insdel marker showed a significant association with IMF content and arachidonic levels (p<0.05). The SSC10 g.71225134G>A marker revealed an association with palmitoleic and ω9 FA levels (p<0.05), while the SSC17 g.61976696G>T marker showed a significant association with IMF content and FA levels of palmitoleic, eicosenoic, arachidonic, monounsaturated fatty acids, and ω9 FA levels. However, no significant association of SSC8 g.47338181G>A was observed with any IMF and FA levels in this study. Conclusion: Four SNP markers (SSC7 g.4937240C>G, SSC9 g.5496647_5496662insdel, SSC10 g.71225134G>A, and SSC17 g.61976696G>T) were found to be associated with IMF and/or FA content traits in commercially crossbred pigs. These findings provide evidence of the novel SNP markers as being potentially useful for selecting pigs with the desirable IMF content and FA composition.
