    Full text link
    Tumbuhan Tembelekan dianggap masyarakat sebagai pengganggu atau gulma karena pertumbuhannya yang dahsyat merambat ke segala arah sehingga mengganggu pada kegiatan pembukaan lahan. Manfaat tradisional daun tumbuhan ini dikenal oleh berbagai suku di Indonesia, tetapi hanya sebagai obat luka yang tidak menarik karena obat luka tergolong obat murah di pasaran. Potensi botani yang tampak terhadap tumbuhan Tembelekan adalah pertumbuhannya yang dahsyat sehingga jika memiliki manfaat ekonomi menjadi sangat potensial ditinjau dari penyediaan bahan baku. Beberapa penelitian ilmiah telah dilakukan terhadap daun dan bunga Tembelekan dan terbuktidaunnya sangat potensial sebagai obat luka yang melebihi obat luka bioplacenton dan bunganya bersifat antioksidan yang sangat kuat.Kandungan metabolit sekunder daun dan bunganya juga sangat bervariasi sehingga masih memungkinkan potensi-potensi lainya dalam bidang farmasi

    Now the emergence of bacterial resistance to antibiotics is a national and global issues that have a significant impact on public health. We report the screening of bacterial symbionts in fruit flies (Drosophilla melanogaster) as a producer of new antibiotic compounds. This study aims to get antibiotic-producing bacterial symbionts in fruit flies (Drosophilla melanogaster). In this study used methods of isolation, purification and antibacterial testing using four test bacteria (Escherichia coli, Staphylococcus aureus, Bacillus subtilis, and Salmonella thyposa). Isolation of fruit flies (Drosophilla melanogaster) that uses peptone solution prepared dilutions to 10-9 and then purification is done by scraping the bacteria on NA medium by repeatedly to obtain pure isolates and subsequently antibacterial test. The results showed that the bacterial isolation 10-8 and 10-9 dilutions allegedly produce antibiotic-producing compound while the antibacterial test using test bacteria showed that the compound obtained from the insulation in the fruit fly (Drosophilla melanogaster) showed the compound to inhibit the growth of bacteria Escherichia coli and Staphylococcus aureus

    Coptosapelta flavescens Korth. is a liana plant from the Rubiaceae family. In East Kalimantan, it is also known as “Akar Tambolekar†or “Merungâ€, it is called “akar†or root as its trunk spreads like a root. The plant’s stems are used by ethnic Dayak in East Kalimantan to overcome high blood pressure and it has been proven to induce vasorelaxation on blood vessels, but the its action mechanism in the endothelial or vascular smooth muscle cells (VSMC) are unknown. Vasorelaxation on the blood vessels could be mediated by endothelial or by the VSMC. This research aims to study in vitro which of them is the mechanism of action of Coptosapelta flavescens Stems (CFS) extract. CFS were taken from the secondary forest in Paser Regency, East Kalimantan Province. Its simplicia were macerated with methanol solvent for three days and twice repeated. Vasorelaxation activity of the blood vessels was tested with rats’ isolated thoracic aorta with endothelial and with the endothelial removed (endothelium-denuded). Both aorta of 3 mm length were soaked into Krebs-Henselheit solution at 37°C, pH 7.4 and aerated with carbogen gas. After they have acclimatized, both aortas were contracted with phenylephrine solution, after reaching peak contraction and plateau, the solution of extract or its solvent (Control) was administered in cumulatively increasing doses. The results show that CFS extracts induce vasorelaxation both in the endothelial-intact aorta and in the endothelial-denuded aorta. At high concentrations, the vasorelaxation activity in the endothelial-intact aorta was weaker than that on endothelial-denuded aorta. This study proves that action mechanism of blood vessels’ vasorelaxation induced by the methanol extract of CFS were more dominantly mediated by the blood vessels smooth muscle; and at high concentrations the endothelial actually weakened the VSMC vasorelaxation activity. Further study is necessary on the mechanism of  action vasorelaxation through the modulation of intracellular or extracellular calcium ion channels of VSMC

    Neonatal sepsis and nosocomial infection are the most common diagnosis of neonatal infections. Selections of antibiotics in neonatal infection should be based on type of bacteria, antibiotics dose and safety in neonates. The aim of this study was to explored type of antibiotics used in Neonatal Intensive Care Unit. Researchers conducted a prospective study of antibiotics used at Dr. Ramelan Navy Hospital neonatal intensive care unit Surabaya. From November 26th 2007 to January 26th 2008, 94 patients (5 preterm neonates and 89 term neonates) were included in this study. Demographic data, antibiotics used, relevant medical histories, laboratory data was recorded prospectively at the wards. Charts for all cases were reviewed.  Early antibiotic use was defined as therapy within 72 hours of life. The most frequently used empiric antibiotic regimens were ampicillin sulbactam with gentamicin (60.2%), ampicillin sulbactam (30.1%), ceftriaxone (6.5%), ampicillin sulbactam with amikacin (1.1%), ampicillin sulbactam with ceftriaxone (1.1%), gentamicin with ceftriaxone (1.1%).  Late antibiotic events also occurred in neonates. Fourty eight point four percent of late antibiotics events were used of ceftriaxone. Antibiotics are prescribed appropriately but earlier discontinuation or switches, which may be complicated either by the inability to confirm causative organism or patient’s condition that showed no improvement, should be practiced

    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. On immunohistochemical examination, it shows that Andrographis paniculata can stimulate of expression of p53 protein and increase the number of epithelial cells experience apoptosis

    Non-Alcoholic Fatty Liver Disease (NAFLD) occurs due to excessive fat accumulation in the liver, triggered by high fat and sugar intake. This study aims to investigate the effect of Nephelium lappaceum peel extract (NLE) on hepatic profile in mice induced with a High Fat High Fructose Diet (HFHFD). The study involved 25 male mice divided into five groups: (1) normal group, (2) HFHFD group, (3) NLE 125 mg/kg bw, (4) NLE 250 mg/kg bw, and (5) NLE 500 mg/kg. HFHFD and NLE administration were carried out for 14 days. On the 15th day, mice were sacrificed and liver was harvested for further analysis. Descriptive analysis was performed for macroscopic and microscopic (histological) liver observations. ANOVA was used to analyze liver index. The results showed that NLE improve fatty liver both macroscopically and microscopically. The liver index also improved significantly in group treated by NLE 250 (p<0,05) and NLE 500 (p<0,0001). The study suggests that NLE exhibits a promising therapeutic potential against fatty liver disease
