Abstract

ABSTRACT   It has been well documented that chemical carcinogen, 7.12 dimethylbenz(a)anthracene (DMBA),  plays a role in the incidence and growth of mammary cancer. Present study was designed to investigate the influence of Andrographis paniculata extract on telomerase activities on DMBA induced breast cancer in the female rat Sprague Dawley strain. DMBA-induced mammary cancer is a useful model to investigate the changes of epithelial cells that occur during mammary cancer progression. Mammary cancer model was induced 10 times twice a week by oral DMBA 20 mg/kg body weight. Mammary cancer occurred in 75 % animals nine weeks after oral administration of DMBA, it was represented with nodule on the mammary gland and the increasing of mammary gland volume compare with normal control F(1.8) = 731.711; p < 0.001. This study was also designed to investigate the effect of Andrographis paniculata extract mammary carcinoma induced by DMBA. Administration of three different dose of Andrographis paniculata (100 mg/kg, 300 mg/kg and 1000 mg/kg) had statistically different with mammary gland volume of DMBA treated rat F (4.17) = 92.777; p<0.05. So, Andrographis paniculata has significant effect on the treatment of DMBA-induced mammary carcinoma. The Epithelial cells were harvested on day 90 and stained with routine histology staining, hematoxylineosin, for morphological qualitative analysis, immunohistochemical examination. The lesions observed from the removed samples ranged widely from benign to malignant. The results showed that DMBA induce cell proliferation, nuclear irregularities, and numerous mitoses and induced cell necrosis. The effect of Andrographis paniculata inhibits cell proliferation and induces apoptosis in cancer cells. On immunohistochemical examination, it shows that Andrographis paniculata can stimulate of telomerase enzyme.   Key word: Andrographis paniculata, DMBA, mammary cancer, cell proliferation     ABSTRAK   Telah dilakukan penelitian efek ekstrak sambiloto (Andrographis paniculata Nees) pada ekspresi telomerase terhadap kanker payudara tikus betina (Sprague dawley) yang diinduksi dengan 7,12 dimethylbenz(a)anthracene (DMBA) menggunakan metode imunohistokimia.

Abstract

The ethanolic extract from the bulb of Eleutherine americana was investigated for acute and subacute toxicity in Balb/C male mice. The parameter used on this research is mortality n hepar  histophatological. During acute toxicity study, bulb plant (0.52, 0,26 and 5.2 mg/kg b.wt) p.o. for 72 hour and subacute toxicity study bulb plant (0.52, 0,26 and 5.2 mg/kg b.wt) p.o. once daily for 30 days. The result of the research shows that ethanol extract with 0.52, 0,26 and 5.2 mg/kg b.wt dosage can be said relatively safe because there is no death signal about 50% in 24 hour and the result of subacute toxicity in observation histophatological in hepar shows there is fibrosis n necrosis with 0.52, 2.6 mg/kg b.wt and 5.2 mg/kg b.wt dosage.

Abstract

Dendrimers are a class of highly branched synthetic polymers that has spherical form consist of three components: core, branch and terminal functional groups. One of dendrimer that has been commercialized is (Poly)amidoamine (PAMAM). PAMAM dendrimer used as a template in the preparation of gold nanoparticles. This research was studied the streched cavities of (Poly)amidoamine (PAMAM) dendrimer generation 4 using in silico method. Structure of (Poly) amidoamine (PAMAM) dendrimers generation 4 downloaded from Building Toolkit (DBT) Library and before the simulation structure was prepared. Then molecular dynamics simulations run using the AMBER program at 37°C in aqueous conditions. From analysis, obtained that the furthest distance of streched cavities at the closest distance from the core, region between residues 2 and 3 is 23.696 Å and at the terminal region between residues 100 and 122 is 58.045 Å
