Papaya Leaf (Carica papaya L.) Active Fraction Effective as Bioinsectiside Against Anopheles species (Diptera: Culicidae) Larva Invitro Study
Views: 2,613Downloads: 400ABSTRACT
Malaria is one of the spread-disease that become a global public health problem included Indonesia. One of the controlling approach of vector-borne disease is by avoiding direct contact of human and mosquitoes. Natural insecticide is an alternative method that can be used. Carica papaya L. is one of the natural insecticide because contains of alkaloid, flavonoid and saponin. This research was aimed to determine the activity of active fraction. was a quasi-experiment research with post test only group design. This research was conducted in April – June 2017. Extraction and fractination was performed in laboratory of MIPA Biologi of Sriwijaya University. The experiment was performed in laboratory of Entomologi Baturaja. The sample of the research was Anopheles sp. larva instar III and IV. Larvacide test used 6 different concentrations which was 0,125%, 0,25%, 0,5%, 1,0% and 2,0% with aquadest as a control. Anova test and post hoc analysis with SPSS 22 software. The result of efficacy test to Anopheles sp. larva showed that N-hexan was the fraction with highest larvacide ability that kill 95% larva at 2% concentration level. Thin layer chromatography test showed a compound of Terpenoid. Activity test of active fraction N-heksan of papaya leaf with the highest mortality rate 92,5% and the lowest 46,25%. LC50 fraction N-heksan of papaya leaf was high toxicity at 24 hours of observation. Anova test showed there was significant influence and difference of various concentration of active fraction of papaya leaf to the mortality of Anopheles sp. larva with p value < α (0,00<0,05).
Key words : Anopheles sp. larva, N-hexan fraction of papaya leaf, larvacide

Efficacy of Topical Coffee Paste to Collagen Density in Wistar Rats Incision Wound
Views: 2,260Downloads: 215Background :Collagen plays a very important role in humans at every stage of wound healing. Coffee contains many antioxidants that stimulate the formation of collagen dermis by increasing the production of Tissue Inhibitor of Matrix Metalloproteinas-1 in the dermis that serves to inhibit the breakdown of collagen. This study aims to determine the efficacy of topical pasta coffee to collagen density.
Methods: Experimental Laboratories Study with pre and post test controlled group design research was undertaken from September to November 2017 at Animal House and Dyatnitalis Laboratory, Palembang. 30 male white rats of wistar strain were divided into 5 groups then performed 2 cm dermal incision and giving various concentration of coffee paste. On the day 0 and 5th after coffee paste, the percentage of collagen density is checked. The efficacy of coffee paste was analyzed by Paired T Test/Wilcoxon while the comparison of efficacy was analyzed by Independent T Test / Mann Whitney then continued with One Way ANOVA Test and Tukey test. Data analysis using SPSS version 18.0.
Results: There was an average difference of percentage level of collagen density before and after vitamin C (p = 0,003), coffee paste 20% (p = 0,043), coffee paste 40% (p = 0,045) and coffee paste 80% (p = 0,011) . In addition, there was an average difference of percentage of collagen density between negative control group with positive control group and 40% coffee paste. From the results of Post Hoc test results showed that there was a difference of percentage of collagen density of negative control group with coffee paste group 40%.
Conclusion: There is efficacy of topical coffee paste on collagen density in various concentrations where the highest increase of collagen density is 246,96% after coffee paste 40%.

Identification of Lactic Acid Bacteria Isolate From Fermentation Food Bekasam
Views: 2,026Downloads: 198Bekasam is a local food from South Sumatera Indonesia, which is obtained through fermentation of fish. Previous study has shown that fermented food contained Lactic Acid Bacteria (LAB) bacteria, such as Lactobacillus plantarum, Lactobacillus sp, Pediococus sp and Weissella sp. The study was conducted to identify isolate LAB from bekasam. Bekasam contained fish, rice, and salt with a certain ratio. Further isolation of isolated LAB isolate, then performed PCR for bacterial analysis. Isolate 1 showed alleged bacteria Staphylococcus sp, non pathogen, while isolate 2 leads to Lactobacillus sp. The PCR results show the suitability of the bands formed between the Lactobacillus standard and the isolates.

The Status of Oxidants and Antioxidants in Children with Nephrotic Syndrome
Views: 1,455Downloads: 195Background: The nephrotic syndrome (NS) resistance and relapse to treatment pose challenges in the management of NS. Several experimental studies on both animals and humans have assessed the association between NS and the balance between the oxidants and anti-oxidants. The study aims to compare the status of oxidants and anti-oxidants of NS patients between the massive proteinuria, the remission, the steroid resistance and the control groups.
Methods: a cross-sectional design to assess the status of oxidants and antioxidants in children with the nephrotic syndrome. The eligible subjects were divided into four groups, the massive proteinuria group, the remission group, the steroid resistant group and the control group. The status of oxidants and anti-oxidant were evaluated with the Malondialdehyde (MDA) and the Total Antioxidant Status (TAS), respectively.
Results: The highest mean MDA levels was observed in the steroid resistant group followed by the massive proteinuria group and the remission group. The mean MDA level of the proteinuria group (massive proteinuria and steroid-resistant) is higher than the remission group. The mean TAS levels in the remission group were higher than the massive proteinuria group, but the difference was not statistically significant. Moreover, the mean difference of SAT between the proteinuria group and without proteinuria was not statistically significant.
Conclusions: The oxidative stress marker (MDA) was higher in the NS patients with proteinuria than the patients without proteinuria. The difference in the total anti-oxidant status in NS patients with massive proteinuria, remission and steroid resistance were not statistically significant.

The Development of Prototype Polyclonal Antibody of Receptor Advanced Glycation of Endproducts (RAGE)
Views: 2,342Downloads: 156Abstract
Background
Receptor for advanced glycation endproducts (RAGE) is a transmembrane protein that belongs to the immunoglobulin superfamily. As its name implicates, it can bind to advanced glycation endproducts, the resulting product of non-enzymatic glycosylation, and it also has the ability to interact with multiple ligands having common motifs as a so-called multi-ligand receptor. The ligands include high-mobility group protein (B)1 (HMGB1), S-100 calcium-binding protein, amyloid-β-protein, Mac-1, and phosphatidylserine. Interaction between RAGE and its ligands activates various cellular processes, including inflammation, proliferation, apoptosis, autophagy, and migration.
Methods
The proccess of isolation protein of RAGE was initiated with extraction protein and purification of RAGE protein. After that, the immunization of Rats was be done to produce Anti-RAGE. The confirmation of Anti RAGE was be done by SDS PAGE and Immunobloting.
Results
The production of Anti RAGE was enough pure compared by Anti RAGE commercial. Anti RAGE was protein that have molecular weight around 35 kD.
Conclusion
The methods that used in this study effective to develop production of anti-RAGE.
