ABSTRACT Background: Recent studies showed that Interleukin-8 (IL-8), activated cytokine immune response which plays an important role in the development of acute and chronic gastritis. Harmless anti-inflammatory therapeutic alternatives have been proposed, for example, the consumption of Sechium Edule Jacq. Swartz (chayote). Antioxidant (flavonoid) and cell regeneration (alkaloid) agents were found in chayote. This study aimed to determine the effect of chayote Sechium Edule Jacq. Swartz extracts on the level of IL-8 in Wistar rats with aspirin- induced gastritis. Subjects and Method: This was a randomized controlled trial (RCT) conducted at the laboratory of Mathematics and Natural Science, Universitas Sumatra Utara from January to February 2020. A total of 35 male Wistar rats was selected for this study and randomly allocated into 7 groups: (1) Negative control; (2) Positive control; (3) 100 mg/ kg BW chayote ethanol extract ; (4) 200 mg/kg BW chayote ethanol extract; (5) 100 mg/ kg BW chayote ethyl acetate fraction; (6) 200 mg/kg BW chayote ethyl acetate fraction; and (7) 20 mg omeprazole. The rats in positive control and treatment groups were induced with aspirin (200mg/ kg BW). The negative control group received no intervention. The dependent variable was level of IL-8 measured by ELISA. The independent variables were treatment status. The data were analyzed by One Way Anova and post hoc test. Results: The mean differences of IL-8 level were not statistically significant between study groups (p= 0.327). Mean of IL-8 level was higher in positive control group (Mean= 160.80; SD= 6.90) than in negative control group (Mean= 141.20; SD= 10.98). The lowest IL-8 level was in 100mg/ kg BW chayote ethanol extract group (Mean= 149.94; SD= 40.4), followed by 200mg/ kg BW (Mean= 152.4; SD= 30.73) and 100mg/ kg BW (Mean= 164.60; SD= 25.04) chayote ethyl acetate fraction groups, 20 mg omeprazole group (Mean= 170.60; SD= 21.58), and 200 mg/ kg BW chayote ethanol extract group (Mean= 176.80; SD= 10.98). Conclusion: The low dose (100mg/ kg BW) chayote ethanol extract has the most potential antiinflammation effect on in vitro gastritis with the lowest IL-8 level of all doses of chayote ethanol extract, chayote ethyl acetate fraction, and omeprazole.

Mekai leaves (Pycnarrhena cauliflora Diels.) (P. cauliflora). Are known to contain flavonoid compounds, tannins and phenolics that act as antibacterial agents and are used in the treatment of eye pain. Staphylococcus aureus (S. aureus) is one of the examples of bacterial diseases of eye pain and also a major cause of many infections in communities and health facilities with cases of resistance to various antimicrobial agents. The purpose of this study was to prove the antibacterial activity of mekai leaves ethanol extract against S. aureus bacteria. This research is an experimental research. The stages of this research began by extracting mekai leaves using maceration method with 96% ethanol solvent. Antibacterial activity was tested by the disc method (Kirby-Bauer) using ethanol extract concentrations of mekai leaves (EPC) 20%, 30%, 40%, 50%, 60%, 70%, and 80%, positive control using 25 μg amoxicillin and negative control using DMSO 10%. The measurement results of inhibition zones of mekai leaf ethanol extract 20%, 30%, 40%, 50%, 60%, 70% and 80% respectively were 8.32 mm, 8.32 mm, 8.32 mm, 8.67 mm, 9.00 mm, 8.67 mm, and 8.33 mm. While the positive control measurement of 25 μg amoxicillin against S. aureus is 28.67 mm and the measurement of 10% negative DMSO control does not produce inhibitory zones, so it can be concluded that the ethanol extract of mekai leaves has antibacterial activity, but the area of ​​inhibition zone produced is smaller than amoxicillin 25 µg. The results of statistical tests using Mann Whitney between negative controls with all EPC concentrations obtained significant differences with p values ​​<0.05, it can be concluded that there is antibacterial activity produced at all EPC concentrations.
