Short Communication:  Stimulatory effect of Curcuma mangga on immune response against Staphylococcus aureus

Abstract. Yuandani, Nugraha SE, Laila L, Silaban SD, Ramadhani F. 2020. Short Communication: Stimulatory effect of Curcuma mangga on immune response against Staphylococcus aureus. Nusantara Bioscience 12: 109-113. Recently, the ethanol extract of Curcuma mangga Val. rhizomes were found to have immunomodulatory activity by enhancing phagocytic ability. This study was carried out to evaluate the effect of C. mangga rhizomes on antibody titer and delayed-type hypersensitivity response in normal and doxorubicin-induced rats against Staphylococcus aureus. The extract was administered orally at doses of 100, 200, and 400 mg/kg body weight (bw) to rats for 72 hours prior to sensitization of Staphylococcus aureus, then continued for 14 days. Doxorubicin (4.67 mg/kg bw) was administered on days 8 and 11 to suppress the immune system. The antibody titer of normal and immune-suppressed rats after the treatment with C. mangga ethanolic extract was significantly higher than the rats with negative control (P<0.05). Ethanol extract of C. mangga also demonstrated stimulation on delayed-type hypersensitivity response which was indicated by the increase of paw volume. The extract at dose of 400 mg/kg bw showed higher immunostimulatory activity than Levamisole as a positive control. The results indicated that the ethanol extract of C. mangga shows immunostimulatory activity, confirming its potential to be developed as a therapeutic agent.

Marchantia Paleacea

Immunostimulants are compounds that can stimulate an immune response by increasing the activity of non-specific and specific components of the immune system (humoral and cellular) against certain infections and diseases. The liverwort plant species Marchantia paleacea Bertol. has long been used as a source of nutrition and empirical medicine. However, scientifically there is still not much research data on immunomodulators in these plants. This study aims to determine the activity of immunomodulators in the ethanol extract of the herb Marchantia paleacea Bertol. in male mice of BALB/c strain. Bioactive compounds from this plant were extracted by maceration method using 96% ethanol. Extract characterization and phytochemical screening were determined according to WHO guidelines and standard procedures from previous studies. The immunomodulatory activity of the extract was tested by carbon clearance method and lymphoid organ index (non-specific responses), primary and secondary antibody titer tests (humoral specific responses), IL-2 cytokine levels and IFN-ɣ from serum secondary antibodies and delayed-type hypersensitivity reaction/DTH (cellular specific response). The results of qualitative phytochemical screening contained flavonoid compounds, saponins, phenolics, tannins and steroids/triterpenoids. The results of the non-specific immune response immunomodulator test showed that the dose of 52 mg/kg bw had the largest phagocytic index of 1.52 which included strong immunostimulation (K > 1.5) and the organ spleen index of 0.55 ± 0.11 which increased significantly compared to the control (p<0.05). The data on the acquisition of specific immune responses in the primary and secondary antibody titer test in the three test extracts resulted in increased titer levels compared to the control and at a dose of 52 mg/kg bw could significantly increase the levels of IL-2 cytokines in the control group (p<0,05). Meanwhile, in the DTH test, doses of 13 and 26 mg/kg bw could significantly increase the thickness of the soles of mice compared to controls (p<0.05).

ABSTRACTEthyl acetate fraction of Som Java leaves (Talinum paniculatum (Jacq.) Gaertn) has been shown to boost innate immunity in the body (non-specific immunomodulatory activity). This study aims to determine the immunomodulatory activity of the specific response of the ethyl acetate fraction of Som Java leaves (Talinum paniculatum (Jacq.) Gaertn). Test specific immune response by using delayed type hypersensitivity test and total antibody titers test. Analysis of data obtained using SPSS version 16.0. Delayed type hypersensitivity test results showed that the ethyl acetate fraction Som Java leaves 50, 100 and 150 mg/kgbw proven to increase cellular immune response and activities comparable to the positive control. Total antibody titer test results showed that the fraction of ethyl acetate Som Java leaves three doses shown to increase the value of primary and secondary antibody titers. Based on the test results specific response can be concluded that the ethyl acetate fraction Som Java leaves have specific immunomodulatory activity.Keywords: Talinum paniculatum (Jacq.)

AbstractThe need for new immunomodulatory drugs is due to the side effects associated with the prolonged use of the currently used immunomodulatory drugs. In this context, the present work aimed to investigate the immunomodulatory effect of an ethanolic concentrated extract from Physalis angulata. The cytotoxicity of samples was determined using peritoneal macrophages though the Alamar Blue assay. The immunomodulatory activity of the ethanolic extract from P. angulata on activated macrophages was determined by measurement of nitrite and cytokine production. The immunosuppressive effects of the ethanolic extract from P. angulata was evaluated on lymphocyte proliferation and cytokine production. The effects of the extract on cell cycle progression and cell death on lymphocytes were evaluated by flow cytometry. Lastly, the ethanolic extract from P. angulata was tested in vivo in toxicological tests and in models of peritonitis and delayed-type hypersensitivity response. The ethanolic extract from P. angulata decreased nitrite, interleukin-6, interleukin-12, and TNF-α production by activated macrophages without affecting the cell viability. In addition, the ethanolic extract from P. angulata inhibited lymphoproliferation and the secretion of interleukin-2, interleukin-6, and IFN-γ, and increased interleukin-4 secretion by activated splenocytes. Flow cytometry analysis in lymphocyte cultures showed that treatment with the ethanolic extract from P. angulata induces cell cycle arrest in the G1 phase followed by cell death by apoptosis. Moreover, mice treated with the extract from P. angulata at 100 or 200 mg/kg did not show signs of toxicity or alterations in serum components. Finally, the ethanolic extract from P. angulata significantly reduced neutrophil migration and reduced paw edema in bovine serum albumin-induced the delayed-type hypersensitivity response model. Our results demonstrate the potential of the ethanolic extract of P. angulata as an alternative for the treatment of immune-inflammatory diseases.

Delayed Type Hypersensitivity Response

Immunomodulator is a compound that can increaase the imuno system. One of the plants that have immunomodulator’s activity is Waru Leaf (Hibiscus tiliaceus). the purpose of this research was to test the effect of immunomodulator by extract of Waru Leaf ethanol on rat male. The activity of immunomodulator was determined by using digital pletysmometer by measuring the differences between the last leg swelling’s volume and the first leg swelling’s volume. The treatment group were divided into 5 groups. Each group consistof 5 rats CMC-Na 0,5% (negative control), Stimuno® 32,5 mg/kgBW (positive control), dose of EEDW 50, 100 and 200 mg/kgBW, and bacteria E.coli as antigen. The results slowed that distribution of EEDW dose 200 mg/kgBW can give the effect of immunostimulant by swelling enthancement compared by CMC-Na 0,5 %. EEDW 200 mg/kgBW that have activity comparable with Stimuno® 32,5 mg/kgBW. Thus, it is concluded that of Waru Leaf extract has immunomodulator effects on delayed-type hypersensitivity response of rat male.
