The Journal of Experimental Life Science (JELS) is a scientific journal published by Postgraduate School, University of Brawijaya as distribution media of Indonesian researcher’s results in life science to the wider community. JELS is published in every four months. JELS published scientific papers in review, short report, and articles in Life Sciences especially biology, biotechnology, nanobiology, molecular biology, botany, microbiology, genetics, neuroscience, pharmacology, toxicology, and Applied Life Science including fermentation technology, food science, immunotherapy, proteomics and other fields related to life matter. JELS is a scientific journal that published compatible qualified articles to the academic standard, scientific and all articles reviewed by the expert in their field. The Journal of Experimental Life Science (JELS) have a vision to become qualified reference media to publish the best and original research results and become the foundation of science development through invention and innovation on cellular, molecular, nanobiology, and simulation work related to life matter rapidly to the community. The Journal of Experimental Life Science (JELS) has objectives to published qualified articles on research’s results of Indonesian researchers in life science scope. JELS encompasses articles which discuss basic principles on natural phenomenon with cellular, molecular, and nanobiology approach.

Abstract

Graft-versus-host disease (GVHD) dan rejeksi (penolakan) pada transplantasi alogenik merupakan kasus terpenting pada masalah transplantasi jaringan. Di lain pihak ketersediaan donor dengan kriteria MHC-matching sangat terbatas. Fakta bahwa kebanyakan organisme hidup sehat tanpa terjangkit penyakit autoimun menunjukkan adanya mekanisme regulasi yang mampu mencegah teraktivasinya sel-sel autoreaktif. Organisme mempunyai mekanisme yang sangat sempurna untuk menghindari respon mematikan terhadap self-antigen. Mekanisme terpenting pada toleransi imunologi ini adalah yang diperankan oleh sel T regulator. Mekanisme toleransi yang dilakukan oleh sel T regulator mencegah teraktivasinya sel-sel autoreaktif ini nampaknya juga terjadi pada transplantasi, baik transplantasi sumsum tulang maupun organ. Pada review ini kami akan membahas aplikasi sel T regulator CD4+CD25+ pada transplantasi alogenik terutama pada transplantasi sumsum tulang (bone marrow transplantation, BMT). Kata kunci: sel T regulator, transplantasi sumsum tulang, toleransi imunologi

Abstract

Immune system is a system of biological structures and processes within an organism that protects against disease. It can be promoted by substance referred as immunomodulator. Usually people use synthetic drug or synthetic immunomodulator to get quick response against the disease. This habit lead to arising side effects such as nausea, bone marrow degradation, thrombocytopenic purpura and agranulocytosis. As alternative, natural immunomodulator derived from active compound in plant. The objectives of this study are to determine the effect of aqueous extract of Moringa oleifera Lam. leaf to the population of  CD4+ and CD8+ T cells, and also B220+ cell on Mus musculus through in vitro study and to analyze the difference of immune response in treatment and non-treatment group (control). In this experiment we used spleen from Balb/C mice. Cells were grown in RPMI medium with three doses (10 µg/ml, 1 µg/ml, 0,1 µg/ml) of M.oleifera extract. The cells were grown for four days culture in the CO2 incubator at 37°C with 5 % CO2. The cells number and expression were analyzed by flowcytometry. Data was analyzed using one-way ANOVA with α=0,05 by SPSS 16.0 for windows with complete randomized design. The result shows that the extract has immunostimulant activity and the low dose (0,1 µg/ml) can  increase the cell number of CD4+ and CD8+, while high dose  (10 µg/ml) significantly increase B220+ cells compared to the control. This result strenghten that M.oleifera has immunomodulator activity to immunity system and worth to be developed into medicinal drug. Keywords: immunomodulator, in vitro, Moringa oleifera, T cell

Abstract

This research was conducted in September to October 2013 in Mamburit Waters, Sumenep Regency. This study was aimed to assess the percentage of coral reefs and acknowkedge the type of the coral reefs. Coral reefs was observed with the Line Intercept (LIT) method laid parallel to the coastline in the depth of 3 m and 10 m in windward and leeward area. Total of 59.88% coral reefs lived in leeward area in 3 m depth includes in good category and the percentage of dead coral reefs and other fauna for 40.12%. In the 10 m depth, 69.19% live coral reefs include as medium category with percentage of dead coral reefs and other fauna for 30.81%. Winward location of 3 m depth has 68.38% live coral reefs in good category and percentage of dead coral reefs and other fauna for 31.62%. Whereas for 10 m depth, 40.86% of live coral reefs include as medium category with percentage of dead coral reefs and other fauna for 59.14 %. Keywords: coral reefs, leeward, windward, Mamburit

Abstract

Immunomodulator is a substance that has an ability to modulate the activity and function of immune system. Gynura procumbens supposed to has benefit as an immunomodulator because of it afficacy to cure many diseases. The aim of this study is to determine the effect and dose variations of G. procumbens extract on biological aspect of CD4+CD62L-, CD4+CD62L+, CD8+CD62L- and CD8+CD62L+ T cells. G. procumbens extract concentrations that used in this experiment were 0 µg /ml, 0.1 µg/ml, 1 µg/ml, and 10 µg/ml. Spleen cells were cultured for 4 days in 5% CO2 incubator at a temperature of 37°C. Cultured cells were harvested and analyzed by flowcytometry to asses cell surface molecule expression. The resulting data were tabulated and analyzed using ANOVA analysis with a significance of 0.05% on SPSS version 16. Results showed that the extract of G. procumbens can increase the proliferation of CD4+CD62L-, CD4+CD62L+, CD8+CD62L- and CD8+CD62L+ T cells compared to the control. Dose of 1 µg/ml showed the highest effect to promote cell activation compared with the dose of 0.1 µg/ml and 10 µg/ml. Dose of 10 µg/ml could suppress CD4+CD62L-, CD4+CD62L+, CD8+CD62L- and CD8+CD62L+ T cells development. This study suggests that the ethanol extract of G. procumbens has benefit as an immunomodulator and involved in the immune system. Keywords: Gynura procumbens, immunity, immunomodulator, in vitro, lymphocytes.
