Abstract

Pseudomonas aeruginosa is an opportunistic bacterium that causes infections in human. The wall cell of its bacteria contains lipopolysaccharide as virulency factors to protect it from human immunity. Lipopolysaccharide can inhibit phagocytosis in the body. Polysaccharide krestin (PSK) from Coriolus versicolor extract contains ?-glucan that can increase phagocytic activity and capacity. This research aimed to identify the effect on polysaccharide krestin from C. versicolor extract on phagocytic activity and capacity of mice exposed by P. aeruginosa. The design of this research was experimental design. There were six treatment groups. The phagocytic activity and capacity were counted on slide smears of mice peritoneal fluid. The data was analyzed by using one way ANOVA. The results of the phagocytic activity and capacity showed that PSK was added before exposure (P1) or after exposure (P2) or before-after exposure (P3) had potential to increase phagocytic activity and capacity. The conclusion of the research was that adding polysaccharide krestin either before exposure or after exposure or both of them could increase phagocytic activity and capacity. The benefits of this research to development of science are expected to reduce human infection and to utilize natural ingredients as immunomodulator.How to CiteWahyuningsih, S. P. A., Savira, N. I.

Abstract

Okra (Abelmoschus esculentus) is reported to have various biological functions such as antioxidant, anticancer and anti-inflammation. However, only few studies have been reported immunomodulatory activities of okra to prevent disease caused by bacteria infection. In this study, the immunomodulatory activities of polysaccharides from okra pods were investigated further through the spleen weight and B-lymphocytes proliferation in mice infected by Staphylococcus aureus. Okra polysaccharides were obtained by water extraction and ethanol precipitation. Okra polysaccharides with doses of 25, 50, 75, and 100 mg/kg BW were orally administrated to mice with or without Staphylococcus aureus infection. Spleen weight was evaluated in both treatment group and control group. B-lymphocytes proliferation was evaluated by MTT assay using LPS induction. Results showed that okra polysaccharide at the doses of 50, 75, and 100 mg/kg increased spleen weight (p < 0.05) significantly. While at the dose of 75 and 100 mg/kg, it increased the B-lymphocytes proliferation (p < 0.05) significantly. There is positive correlation between the spleen weight and B-lymphocytes proliferation by 73.3%. These result reveal that okra polysaccharide could improve the immune response and be utilized as a novel candidate of neutraceutical.
