Abstract

Background: Systemic Lupus Erythematosus or SLE is a chronic autoimmune disease with varied clinical manifestations. SLE prevalence in Indonesia is being dominated with female, especially in their productive age. Certain etiology of SLE is still unknown until now, but genetic factors and immune system are being estimated as the primary factors. The first line therapy of SLE is cyclophosphamide. Unfortunately if being consumed more than six months, cyclophosphamide has several side effects, like bone marrow depression, infections, alopecia, hemorrhagic cystitis, and infertility. Because of that side effects, herbal medicine is being developed nowday. One of them is Andrographis paniculata Ness. leaf. The aim of this study was quantitative cytotoxic test for Andrographis paniculata Ness. leaf on T lymphocyte culture of Systemic Lupus Erythematosus. Methods: This study was anexperimental study. Subjects in this study were patients with SLE who appropriated SLEs criterias and normal people without allergy and autoimmune diseasess history. This study was done by doing T lymphocyte culture from intravenouss blood sample and observing cells absorbance with ELISA reader. Collected data were used for determining live cells percentage (IC50) and analyzed with Statistical Product and Service Solution (SPSS) 11.00 for Windows. Mean resistance data was tested by linear regression test. Results:The result showed that IC50 dose of Andrographis paniculata Ness. leaf extract treatment on SLE samples was smaller than the normal people. In Andrographis paniculata Ness. leafs extract treatment, IC50 in SLE = 0.00074 and in normal people = 0.19584. Conclusion: Andrographis paniculata Ness.leaf extract had stronger cytotoxic effect on T lymphocyte culture of patients with SLE than the normal people. Keywords: Systemic lupus erythematosus, Andrographis paniculata Ness. leaf extract, T lymphocytes, IC50

Abstract

Background: This study aimed to know the inhibitory effect of the etanol extract of mangosteen rind (Garcinia mangostana, Linn.) on the growth of Candida albicans in vitro. Methods: The method used in this study was quasi-experimental laboratory research. The subject was the ethanol extract of the mangosteen fruit (Garcinia mangostana Linn.) rind. Candida albicans grown on sabouraud dextrose agar were treated with 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, and 100% of the ethanol extract of mangosteen rind (Garcinia mangostana, Linn.), as well as fluconazole 25?g (drugs that were already on the market) as positive control for 24 hours at 37 C on petri dish. The data of diameter of inhibition zone obtained were analyzed with regression-correlation test using SPSS 11.5 for windows. Results: The diameters of inhibition zone on culture of Candida albicans treated with the ethanol extract of the mangosteen fruit with concentration of 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, and fluconazole 25?g were 0 mm, 0 mm, 1.75 mm, 1.75 mm, 2.00 mm, 2.00 mm, 3.00 mm, 3.50 mm, 3.75 mm, 3.75 mm and 0 mm, in a row. The regression-correlation analysis showed that the correlation (r) between the diameter of inhibition zone and the levels of ethanol extract of mangosteen rind was 0.936 (p 0.000). Conclusion: The ethanol extract of mangosteen rind (Garcinia mangostana, Linn.) had antifungal effect on the growth of Candida albicans in vitro. Keywords: antifungal effects, ethanol extract of mangosteen rind (Garcinia mangostana Linn.), Candida albicans.
