Screening And Tlc-bioautography Analysis Of Antimicrobial Compounds From Some Sponge Extracts Originated From Barrang Lompo Sea Island, South Sulawesi

Sponges is one of the invertebrate Porifera phyla that produce active compounds with various structures and one of the biological activity as antimicrobial. The purpose of this research was to find out the sponge extracts that can inhibit microbial growth and potential of antimicrobial active compounds from sponge at Barrang Lompo Island. The microbes used were Escherichia coli, Salmonella typhii, Staphylococcus aureus, and Candida albicans. The sponge extracts were obtained by maceration 14 sponge samples with methanol, followed by partition using chloroform and methanol, then TLC-bioautography toward the active extract. The results showed that methanol extracts of sponge with code BRLP-009 and 010 have the most potential effect as antimicrobial agent

Sinergitas Aktivitas Antibakteri Dari Kelopak Bunga Rosella Dan Kitosan Terhadap Staphylococcus Aureus: Synergistic Antibacterial Activity of Roselle Calyx and Chitosan Against Staphylococcus Aureus

Currently, the antibacterial research is increasingly promoted primarily from natural materials, due to the increasing number of pathogenic bacteria that have been resistant to existing antibiotics. One of the pathogenic bacteria that has been much resistant to antibiotics is Staphylococcus aureus. Rosella calyx (Hibiscus sabdariffa  L.) and chitosan are known to have antibacterial activity. The aim of this study to find out the antibacterial synergy of the  roselle calyx extract and chitosan against. S.aureus ATCC 33592. Rosella calyx was extracted by maceration using 80 %  ethanol, while chitosan is obtained from deasetilation chitin of shrimp husk. Test antibacterial synergism using checkboard assay method by calculating the minimum inhibitory concentration (MIC)  using microdilution assay. The results showed minimum inhibitory concentration (MIC) value of roselle calyx extract and chitosan were 1250 ppm and 50 ppm, respectively.  MIC value of rosella calyx extract in the presence of chitosan was 625 ppm, while the value of MIC chitosan in the presence of rosella calyx extract was < 0.19 ppm. Fractional Inhibition Concentration Index (FICI) was < 0.5 which concluded that the combination of roselle calyx extract with chitosan has a synergistic antibacterial effect on S.aureus ATCC 33592

The Effect of Turmeric and Garlic Phytobiotic Addition with Different Duration Storage on the Fungal Colony in Feed

Turmeric and garlic phytobiotic contain bioactive substances, each of which has a function as an antifungal. The study aims to determined to test the ability turmeric and garlic phytobiotic pressed fungal colonies in the feed with different storage time. The data were analyzed by a factorial experimental design with 5 treatments 4 replications and 2 repetitions. The first factor types phytobiotic and the second factor was storage duration. R0 = basal ration (without phytobiotic), R1 = basal ration + 0.3% synthetic antifungal, R2 = basal ration + 2.5% turmeric, R3 = basal ration + 5% garlic, R4 = (basal ration + 2.5% turmeric+ 5% garlic. W0, W1, W2 and W3 respectively with storage time 0, 2, 4 and 6 weeks. Samples were taken from each experimental unit homogeneously. The results showed the average fungal colonies of garlic phytobiotic treatment (26.06±44.76 CFUx103/g) in 2-week storage time (25.20±22.52 CFUx103/g) lower than the provision of synthetic preservatives (57.75±52.03 CFUx103/g) and the control treatment (74.87±70.69 CFUx103/g). Fungal colonies increases rapidly with increasing length of time of storage. The conclusion of this study was that the additon of turmeric and garlic phytobiotic capable as an antifungal in feed

The Impact of the Frequency of 7,12- Dimethylbenz [á] Anthracene (Dmba) Administration on the Formation of Dysplasia and Squamous Cell Carcinoma on the Skin of Albino Mice

Introduction: Dosage and frequency of 7,12-dimethylbenz[á] anthracene (DMBA) com- pound exposure suspected to affect the rapid growth of squamous cell carcinoma (SCC) in albino mice. Objective: find out the impact of DMBA exposure to dysplasia and SCC formation on albino mice. Methods: Twenty-five albino mice were divided into five groups, namely: Group 1 is the control (acetone), group 2 is 5 albino mice given four times DMBA100 µg exposure for eight weeks, group 3 is 5 albino mice were given eight times DMBA100 µg exposure for eight weeks, group 4 is 5 albino mice were given twelve times DMBA100 µg exposure for eight weeks, and group 5 is 5 albino mice were given sixteen times DMBA 100 µg exposure for eight weeks. Histopathological examination were conducted to assess histopathological feature including inflammation, dysplasia, and SCC. Results: There is a significant effect of the frequency of DMBA exposure to the clinical figure and against histopathological feature of the skin albino mice.Conclusions: Dosage and fre- quency of DMBA exposure affect the occurence of dysplasia and SCC, which are in- creasingly being DMBA exposure will accelerate the growth of SCC. The frequency of the most widely pose a SCC in DMBA 100 µg sixteen times exposure group, twice a week for eight weeks

Aktivitas Anti Mycobacterium Tuberculosis Strain H37Rv Dan MDR (Multi Drug Resistant) Dari Ekstrak Rimpang Curcuma Mangga Val.: Anti Mycobacterium Tuberculosis Activity Strain H37Rv and MDR (Multi Drug Resistant) From Curcuma Mangga Val. Rhizome Extract

TB is an infectious disease caused by the bacterium Mycobacterium tuberculosis. Empirically the plants that have long been used in medicine are Curcuma mangga  rhizome, which shows pharmacological activity as an anti Mycobacterium tuberculosis drug. The objective of the research is to determine the ability of hexane and methanol extracts of Curcuma mangga in inhibiting the growth of Mycobacterium tuberculosis Strain H37Rv and MDR. The extraction of Curcuma mangga rhizome was conducted by maceration methode using hexane and methanol as the solvents, respectively.  Both of extracts were made in 1000 dan 500 ppm concentration, then tested for anti Mycobacterium tuberculosis activity using MODS (Microscopic Observation Drug Suspectibility) method. Determination of anti M.tuberculosis activity was based on microscopic observation on Mycobacterium tuberculosis colony in cord formation. The results showed that hexane and methanol extract in 1000 ppm concentration inhibited the growth of Mycobacterium tuberculosis Strain H37Rv dan MDR. However in 500 ppm only n-hexane  extract showing the inhibiton activity. In conclusion, n-hexane extract have the ability to inhibit the growth of Mycobacterium tuberculosis Strain H37Rv dan MDR.&nbsp
