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. Diketahui model kanker payudara dengan induksi DMBA untuk menginvestigasi perubahan dari sel epitel yang terjadi selama prorses karsinogenesis kanker payudara. Pemberian ekstrak sambiloto pada tikus yang mengalami kanker payudara menyebabkan penurunan volume tumor dan ditinjau dari aspek hispatologi dan imunohistokimia adanya ekstrak sambiloto menyebabkan penghambatan proliferasi sel, penurunan ekspresi telomerase dan meningkatkan apoptosis.

Abstract

ABSTRAK Pelepasan natrium diklofenak dari Sediaan Transdermal Patch Tipe Matriks dengan kombinasi polimer etil selulosa (EC) N-20 dan polivinilpirolidon (PVP) K-30 telah diteliti. Pada penelitian ini sediaan transdermal patch tipe matriks yang mengandung natrium diklofenak dibuat dengan kombinasi polimer etil selulosa (EC) N-20 dan polivinilpirolidon (PVP) K-30 pada perbandingan yang berbeda ( 9:1 (Formula I); 8:2 (Formula II); dan 7:3 (Formula III)). Persentase (%) moisture content dihitung dari perbedaan berat relatif pada penimbangan akhir. Uji homogenitas permukaan patch dilakukan dengan menggunakan metode Scanning Electron Microscopy (SEM). Uji disolusi dengan media larutan dapar fosfat salin pH 7,4 ± 0.05 sebanyak 500,0 mL yang terlebih dahulu dipanaskan sampai mencapai temperatur percobaan 37 ± 0.5°C diaduk pada kecepatan 50 rpm. Hasil dianalisis menggunakan SPSS dengan metode ANOVA one way dengan tingkat kepercayaan 95% (a = 0,05). Berdasarkan penelitian ini, penggunaan polimer kombinasi antara etil selulosa (EC) N-20 dan polivinilpirolidon (PVP) K-30 dapat meningkatkan fluks pelepasan natrium diklofenak dari sediaan patch natrium diklofenak. Perbandingan 7:3 dari etil selulosa (EC) N-20 dan polivinilpirolidon (PVP) K-30 adalah kombinasi yang terbaik untuk sediaan patch natrium diklofenak karena konsistensi bentuk fisik serta nilai fluks pelepasan dan penetrasi yang dihasilkan lebih besar dari perbandingan lainnya. Kata Kunci : Pelepasan Sodium diklofenak, plasticizer, kombinasi matrix dari EC N-20 dan PVP K-30 ABSTRACT The sodium diclofenac realeased from transdermal patch of combination of ethyl cellulose (EC) N-20 nd polyvinyl pyrollidon (PVP) K-30 was investigated. In this study, matrix-type of transdermal patchntaining diclofenac sodium were prepared using polymeric combination of EC N-20 and PVP K-30 in various ratios ( 9:1 (Formula I); 8:2 (Formula II); and 7:3 (Formula III)). The percentage of moisture content was calculated as a difference between initial and final weight with respect to final weight. The homogeneity of patch surface was determined using fluorescence microscope and scanning electron microscope (SEM). Released test using dissolution apparatus were carried out in 500 mL of phosphate buffer saline pH 7.4 ± 0.05 at temperature 37 ± 0.5°C with speed of swirl 50 rpm. Results were analyzed by statistic programmed of SPSS using one way analysis of variance with degree of believed 95% (α = 0,05). It can be concluded that the combination of EC N-20 and PVP K-30 at ratio 7:3 was the best choice for manufacturing transdermal patch based on physicochemical and the release profile.

Abstract

ABSTRACT The non-TBC lower respiratory infection is a kind of infection that can attack bronchus, bronchioles and lung, the clinical manifestation can chronicle and severe. Generally the caused in children is virus and bacteria while in adult is bacteria, which is using antibiotics in medical attention. The purpose of research is to find out the infection pattern and the kind of antibiotics and to evaluate the using antibiotics based on effectivity. The non-experimental research that was form in a retrospective survey was done through medical record of patient with the lower respiratory infection in the time limit of January-June 2005 in Panti Rapih Hospital. The using of antibiotics was surveyed from medical record then analyzed using quantitative descriptive and presented in percentage. The results obtained showed that the contraindications and adverse reactions of drugs are not found, the incidence of drug interactions by 22 (16%) of 137 cases and of 29 types of antibiotics are used there are 7 species (24%) of potential antibiotic drug interactions. Several cases of potential interactions occurs not show clinical manifestations in patients. To avoid unwanted adverse reactions serum creatinine should be monitored especially in the use of aminoglycoside antibiotics group.

Abstract

ABSTRACT Quantitative Structure-Activity Relationship (QSAR) study have been conducted to antimalarial active compounds of cassane-type diterpenes isolated from seed kernels of Bagore (Caesalpinia crista Linn.), using the atomic net charges data resulted from AM1 method of semi-empirical calculations. The aim of this research is to determine the mathematic equation model of quantitative structure-activity relationship from antimalarial active compounds of cassane-type diterpenes isolated from seed kernels of Bagore (Caesalpinia crista Linn.) using the electronic parameter of AM1 method. The best QSAR equation model was determined by multiple linier regression analysis and tested by leave-one-out type of cross validation methods. The result indicates that the biological activity is represented by a linier function of activity versus atomic net charges of C1, C2, C3, C4, and C6 which is expressed by : Log (1/C) = -7,362(+ 4,251) qC1 +3,258 (+ 4,590) qC2 + 11,038 (+4,485) qC3 + 29,421 (+20,542) qC4 + 19,849 (+6,171) qC6 + 8,541 (+2,256) The equation is significant at 95% level.

ABSTRACT This research aims to create a lotion formula containing essential oils of turmeric (Curcuma longa) as well as find out its activities as Aedes aegypti repellent. Turmeric rhizome steam distilled essential oil fraction to be taken. Lotion is made by mixing turmeric oil with a base with a concentration of 10%, 15%, and 20%. Preparation activity tested against Aedes aegypti mosquito that is by calculating the protection time. As a negative control use basis only, whereas the positive control used the patent lotion. From the test results obtained activity results lotion protection time in a row were 1.33 ± 0.34, 3.33 ± 0.38, 11.43 ± 1.50, and 21.67 ± 2.08 minutes. Preparations that have their greatest protection is lotion which contains turmeric oils of 20%. In addition to the activity test also tests the physical properties of turmeric oil lotion, i.e organoleptic test, pH, spreadibility test, and viscosity. All tests of physical properties were fullfilled the criteria lotion preparations. Then the pH and spreadibility tested again after being stored for 1 month. pH of lotion not experience significant differences compared to when newly created, while the spreadibility changed after being stored 1 month.
