Abstract

Premenopause is a physiological condition in a female individual that has entered the aging period, a condition usually characterized by elevated MDA levels and decreased estrogen levels. The objective of this study was to determine the level of ovarian MDA and estradiol serum levels of premenopausal white rat blood after oral turmeric powder treatment. The animals used were 30 female Wistar strains white rat, age 12 months with an average body weight 200-250 g. The animals were divided into 6 groups, namely the negative control group (P0) with 4 ml/day distilled water treatment; positive control group (P1), this group was treated with pure curcumin powder 6.75 mg/kg BW; treatment group 1 (P2), group was treated with turmeric powder 100 mg/kg BW; treatment group 2 (P3); treatment group 3 (P4); and treatment group 4 (P5), these group were treated with turmeric powder at 200 mg/kg BW; 400 mg/kg BW; and 800 mg/kg BW dose respectively. Oral Treatment was administered daily for 27 days. Blood collection was performed on days 0, 14, and 28. The ovarian collection was conducted on day 28. MDA ovarian level was measured using TBA method and blood serum estradiol level was measured using ELISA method. The results exhibited that the positive control group (P1) and the treatment group (P2-P5) showed significantly lower ovarian MDA levels compared with the negative control group (P0). The turmeric powder dose 200 mg/kg BW (P3) can increase estradiol levels by day 14 (3.32 ± 0.26 ρg/mL) and at day 28 (4.01 ± 0.26 ρg/mL).

Abstract

This study aimed to prove the existence of anti-plasmodial activity from Tinospora crispa (T. crispa) stem extracts and to determine the IC50 values as well as the best T. crispa stem extract concentration in inhibiting the growth of P. falciparum 3D7 strain in vitro. The degree of parasitemia was observed by counting the number of infected red blood cells in Giemsa stained blood films under a light microscope with a magnification of 1000x. The Plasmodium DNA concentration was measured using flow cytometryc with Propidium Iodide (PI) staining. Analysis of fourier transform infrared (FTIR) spectrophotometer showed that the methanol extracts of T. crispa stem contained tinocrisposide compound. From the quantitative test results of Thin Layer Chromatography (TLC), it was obtained 0,22 % alkaloids that might contain compounds of berberine and palmatine. One way ANOVA statistical analysis showed that the degree of parasitemia and the concentration parasite DNA of treatment group of dose of 2,0mg/ml was significantly lower compared to the control group after 48 hours (p=0,001) and 72 hours (p=0,001) of incubation. The T. crispastem methanol extract has anti-plasmodium activity, with IC50 values between 0,27 mg/ml and 0,29mg/ml, and the effective dose to inhibit the growth of P. falciparum 3D7 strain is 2,0 mg/ml with reducing parasitemia degree by 47,12% and 56,83% after 72 hours of incubation. From this study shown the methanol extract of T. crispastem was able to reduce the parasitemia degree of P. falciparum 3D7 strain in vitro and could to be a potential candidate for anti malarias.Keywords: Antiplasmodium, methanol extract, T. crispa, Plasmodium falciparum

Abstract

Treatment using herbs is currently growing rapidly. Compounds in herbal plants can cure various degenerative diseases. The study aims to analyze the potency of nimbin, deacetylnimbin, salanin, and deacetylsalanin compounds in the neem leaves extract to inhibit target proteins namely PPARg and ERa. PPARg is the main regulator of the function of adipose tissue microvascular endothelial cells (aMVECs) while ERa is a protein that mediates all estrogen effects and it is important in the growth of prostate and breast cancer. Inhibition of ERa can prevent the proliferation and growth of breast cancer cells by affecting the performance of estrogen which binds to hormonal receptors and causes inhibition of breast cancer cell proliferation. The results of in silico analysis show that deacetylnimbin can inhibit ERa protein. The docking analysis shows that deacetylnimbin has the potential to replace tamoxifen as a breast cancer drug. The other studies such in vitro and in vivo are needed to validate in silico study.

Abstract

Diabetes mellitus is a metabolic disease that is caused either by the decrease of insulin secretion frompancreatic β cells or the insensitivity of target cells against insulin. High glucose levels (hyperglycemia condition)can trigger the formation of free radicals, the main cause of diabetes micro and macrovascular complications. Theformation of free radicals and AGE (advanced glycation end-products) is assumed to became the key factor in thedecline of granulocyte cell production as well as the disruption of these cells functional activity. The purpose ofthis research was to determine the role of VipAlbumin® in inhibiting the adverse effects of increased blood glucoselevels, which highly influence the production of granulocyte. This study was divided into in vitro and in vivostage. BALB/C mice were used as experimental animals at in vivo stage and induced to undergo diabetes through100 mg/kg BW streptozotocin (STZ) injection at the age of 5 days. VipAlbumin® administered orally for 14 days,which began when mice reached the age of 14 weeks. The administration of VipAlbumin® divided into 3 dosesi.e. 0,01664 mg/gr BW (1st dose), 0,416 mg/gr BW (2nd dose), and 10,4 mg/gr BW (3rd dose). The further step wasa flowcytometric analysis to see the development of granulocyte cells relative amount, which were isolated fromthe bone marrow. The result of this analysis shows that VipAlbumin® administration, particularly at the 2nd and3rd dose, were able to modulate granulocyte cells development in the bone marrow.

Abstract

Immune system is a system of biological structures and processes within organism directed to protect against invaded pathogen. Cellular and humoral immune system mediated by immunocompetent cells such as CD4+ T cells, CD8+ T cells, CD4+CD25+ T cells, and B220 cells play important role for maintaining immunological surveillance. The purpose of this study was to determine the effect of ethanolic extract of  G. procumbens leaves (EEGL) on the profile of CD4+ T cells, CD4+CD25+ T cells, and B220+ cells. Splenic cells were isolated from BALB/c mice and cultured in RPMI1640 medium in the presence of EEGL. After 4 days of incubation, cells were harvested, stained with antibodies and analyzed by flow cytometer. The data were analyzed by one-way ANOVA with α= 0.05 and Tukey test using SPSS 16.0 for windows. The results showed that the extract of  G. procumbens could increase proliferation of CD4+CD62L T cell, CD4+CD25+T cells, and B220+ cells compared to the control. Here, we showed the biological effect of G. procumbensas medicinal herb with immunomodulatory activity andthe dose of 0.1 µg/ml and 1.0 µg/ml could promote T cell activation compared to the highest dose of 10 µg/ml. In terestingly, the dose of 10 µg/ml rather promote than inhibit B cell proliferation.
