Abstract

Banana (Musa paradiasiaca var. sapientum) is the world's most popular fruit-bearing crop, with rising consumption and waste. This study aimed to measure the metabolite compound and evaluate the gastroprotective properties of a banana peel-purified methanol extract. Animals test used in this study were divided into six groups: Group One received NaCMC 0.5%, Group Two received sucralfate, Group Three received aspirin 1000 mg/kg body weight, and groups four, five, and six received PBP at doses of 200 mg/kg body weight, 400 mg/kg body weight, and 600 mg/kg body weight, respectively, for seven days. Except for group 1, all groups were induced with aspirin at 1000 mg/kg body weight on the eighth day. The result of this study exhibited banana peel containing total phenolic, flavonoid, and tannin compounds with concentrations of 33.45 mg GAE/g, 19.92 mg QE/g, and 0.16 %, respectively. The results showed that pure extract of Musa paradiasiaca var. sapientum fruit peel can reduce the incidence of gastric ulcers by decreasing the ulcer index (p<0.05).. The results suggested that Musa paradisiaca var. sapientum peel has a gastroprotective effect against aspirin-induced gastric ulceration.

Abstract

Macrophages are essential in tissue homeostasis and immunity, but also contribute to disease development and progression. Chronic kidney disease (CKD) is characterized by interstitial infiltration of macrophages, the density of which correlates inversely with kidney survival. Studies have shown that yacon (Smallanthus sonchifolius) has beneficial effects on CKD. Therefore, this study aimed to investigate the effects of yacon leaf extract on mice with subtotal nephrectomy by evaluating the M1 and M2 macrophage counts and mRNA expressions of monocyte chemoattractant protein-1 (MCP-1 and IL-10. The mice were randomly divided into five groups: SO (negative control: underwent sham operation), SN (positive control: underwent subtotal nephrectomy), and yacon-treated groups: YK1, YK2, and YK3 (underwent subtotal nephrectomy, given peroral yacon leaf extract for 14 days with doses of 24,5 mg/kgBW/day, 49 mg/kgBW/day, and 98 mg/kgBW/day, respectively). The macrophage subtypes were assessed using immunohistochemistry anti-CD68 for M1 and anti-Arginase I for M2. MCP-1 and IL-10 mRNA expressions were analyzed using semi-quantitative PCR. Results showed that yacon leaf extract could significantly lower the M2 macrophage count (p<0.001) and the mRNA expressions of MCP-1 and IL-10 in all yacon-treated groups when compared to the SN group. However, the M1 macrophage count was only lower in the YK2 group (p=0.009). In conclusion, the administration of yacon leaf extract could attenuate kidney injury by lowering the macrophage count and the expression of MCP-1 and IL-10.
