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.

Background: The process of wound healing is influenced by various factors such as age, hormones, and wound care. Wound care is done to accelerate wound healing which can be done by various methods, one of them is traditional care. Traditional wound care can use medicinal plants. Rhodomyrtus tomentosa is a medicinal plant that has an antioxidant, anti-inflammatory, antitumor and antibacterial content. Thus this study aims to evaluate the effectiveness of the antiseptic solution of the Rodhomyrtus tomentosa leaf extract on wound healing in male Wistar rats. Method: this research is pure experimental research with post test only control group design. Thirty male white rats were divided into five groups, namely negative control, positive control, Rhodomyrtus tomentosa leaf extract 15%, 30%, and 60%. Rhodomyrtus tomentosa leaf extraction was carried out by maceration method with 70% ethano solvent. The extraction results are divided into 3 concentrations (15%, 30% and 60%). The wound healing process was evaluated by measuring the length of the wound manually from 0 to 10 days in each group. Meanwhile, the number of fibroblast cells was calculated through hematoxylin eosin (HE) staining and observed using an Olympus CX41 microscope with a 10x magnification and objective lens magnification in 3 fields. Result: There was a significant difference in the reduction in wound length (p =< 0,000) between the five experimental groups (Rhodomyrtus tomentosa leaf extract solution 15%, 30% and 60%, negative control and positive control. Solution of rhodomyrtus tomentosa leaf extract accelerated the increase in the number of fibroblasts compared to the negative control group (p = 0.003), but did not make a difference (p = 0.403) with the positive control group. Rhodomyrtus tomentosa leaf extraction solution had the same microscopic effect on the number of fibroblasts with a positive control group given 0.9% NaCl solution. Conclusion: There was a significant difference in the number of fibroblasts between all groups, but no difference in wound healing length.

Tooth extraction is a process of removing teeth from the alveolar bone. In wound healing, fibroblast are very important cells. The main purpose of this study was to determine the effect of mobe leaf 1% and 3% extract gel (Artocarpus lakoocha) on fibroblast proliferation in post extraction tooth socket wound healing. This research used 16 samples of wistar rats, divided into 4 groups, a positive control group, a negative control group and a 1% and 3% mobe leaf extract gel group. The left mandibular incisors were extracted, then 1% and 3% gels of mobe leaf extract were applied on day 1 to day 7. Data analysis was calculated using the Kruskal-Wallis test on clinical data and one way ANOVA test for microscopic. The result of the socket wound healing activity test for a good concentration of mobe leaf extract gel was 3%. This research shows significant resultith p-value of 0.018 (< 0.05) on the closure of the socket wound clinically which means the closure of the wound accelerates because of the mobe leaf 3% extract gel treatment. The distance of fibroblast on microscopically shows significant resultith a p-value of 0.002 (< 0.05), which means that there was an enlargement of the distance fibroblast at the socket wound closure with application of mobe leaf 3% extract gel. From the results of the study it can be concluded that mobe leaf 3% extract gel has the best ability to show acceleration the closure of the socket wound either clinically or microscopically.

Trigona honey (TH) is well known for its therapeutic characteristics. To date, the study of Trigona honey as a prophylactic or immune booster prior to the bacterial infection of the invivo model is not well covered. This study aims to investigate anti-inflammatory and immune activities in Wistar rats infected with respiratory infection following with Trigona honey. 25 Wistar rats were assigned to possitive groups, negative control group, positive control group was fed TH (5 g / kg body weight) orally, the untreated group was infected with Staphylococcus aureus to induce respiratory infection, the treated group has been infected with S. aureus followed by treatment with TH at a dose of 1.5 ×108 CFU / mL and the preventive group ingested TH one week before S. aureus infection. Blood was obtained for biochemical analysis. Lung tissues have been collected for molecular examination. The results showed a significant decrease in serum levels of ALT, AST, urea and creatinine in the preventive and treated groups, serum IgG increased significantly (P<0.05) in the preventive and treated groups, IFN-y increased in the preventive group while decreased in the treated group, and IL-8 increased in the treated group while decreased in the preventive group. The mRNA expression of AGP is up-regulated in the positive control, preventive and treated groups. The α2-MG, TNF-α , and mRNA expressions showed lower regulation after administration of TH in preventive and treated groups. The results show the ability of TH to counteract immune and inflammatory changes in serum levels and gene expressions.

This study investigated the hepatoprotective effect of methanol seed extract of Citrus tangerina on liver damage induced by paracetamol in laboratory rats. Wistar rats were used in this study and categorized into five groups. Groups 1 and 2 received 10 ml/kg normal saline orally, groups 3 and 4 were administered 200 mg/kg and 400 mg/kg respectively of Citrus tangerina seed extract orally, while silymarin 100 mg/kg served as standard drug treatment for group 5. Following six (6) days of pretreatment with the extract, hepatotoxicity was induced with paracetamol 3 g/kg (orally) in all the groups except the positive control group. At the end of the experiment (24 hours after induction), blood samples were collected under diethyl ether anaesthesia for biochemical markers of liver enzymes and antioxidative stress and the liver was harvested for histopathological studies. Both doses (200 mg/kg and 400 mg/kg) of Citrus tangerina seed extract significantly (p < 0.05) reduced the liver enzymes level, but significantly (p < 0.05) increased antioxidant enzymes when compared with the negative control group. Liver histology showed that the Citrus tangerina seed extract prevented hepatic injury induced by paracetamol. The methanol seed extract of Citrus tangerina possesses antioxidative and hepatoprotective effects.
