<![CDATA[Pengembangan vaksin terhadap malaria yang merupakan penyakit yang mematikan tetap menjadi satu prioritas kesehatan masyarakat global, termasuk pemanfaatan parasit iradiasi sebagai bahan vaksin. Imunisasi dengan sporozoit iradiasi mampu memberikan imunitas protektif pada hewan coba dan sukarelawan. Mekanisme sistem kekebalan tubuh ini banyak dipelajari karena merupakan faktor penting dalam pengembangan vaksin, demikian halnya profil dan/atau ekspresi protein pasca iradiasi yang terkait erat dengan keamanan dan aspek lain dari bahan vaksin. Meskipun telah melalui penelitian yang ekstensif, vaksin yang aman dan protektif belum dapat diperoleh karena masih diperlukan pengetahuan yang lebih mendalam mengenai mekanisme imunitas dan protein dalam litbang malaria. Hasil penelitian menunjukkan bahwa sel limfosit T berperan penting dalam pengaturan respon imun dan pembentukan memori imunologik yang mengontrol dan mengeliminasi infeksi. Sitokin proinflamasi seperti interleukin-12 (IL-12), interferon-gamma (IFN-?), dan tumor necrosis factor alpha (TNF-?) juga merupakan mediator esensial dari imunitas protektif pada malaria eritrositik. Berbagai pendekatan lain terkait respon imun seperti genetika molekuler saat ini sedang dilakukan. Studi juga menunjukkan bahwa profil protein bergantung pada beberapa faktor yang akan dibahas lebih lanjut dalam makalah.The development of vaccine against malaria as the deadly disease remains the global public health priority; and it includes the use of irradiated parasites as vaccine materials. Immunization with irradiated sporozoites could provide protective immunity in animals and volunteers. The mechanism of this body immunity system has been studied widely due to its important role in the development of vaccines and profiles and/or protein expression post-irradiation which are closely related to safety and other aspects of vaccine materials. Even though extensive research has been done, a safe and protective vaccine remains elusive because more deeply knowledge on immunity mechanism and protein in malaria research is still needed. Results showed that T-cell lymphocytes have an important role in the regulation of immune response and in the formation of immunological memory which controls and eliminates the infection. Pro-inflammatory cytokines such as interleukin-12 (IL-12), interferon-gamma (IFN-?), and alpha tumor necrosis factor (TNF-?) are also essential mediators of protective immunity in erythrocytic malaria. Various other approaches related to immune response such as molecular genetics has been carried out. The study also showed that protein profile is depended on some factors that will be discussed further in the paper.]]>

<![CDATA[Endophytic Streptomyces sp. AEBg12 isolated from Zingiber cassumunar (Bangle) is known to produce pancreatic lipase inhibitory compound. However, the characteristics of this active compound has not been reported yet. This study aimed to determine the characteristics of pancreatics inhibitory compound produced by Streptomyces sp. AEBg12 and to assess the role of endophytic actinobacteria in producing pancreatic lipase inhibitor using endophytic-free bangle tissue culture, wild bangle and compared with the activity of Streptomyces sp. AEBg12 endophytes. Supernatant of Streptomyces sp. AEBg12 was extracted using ethanol, ethyl acetate, and n-hexane solvents. Toxicity test was performed using larvae of shrimp Artemia salina. The results showed that the best solvent to obtain pancreatic lipase inhibitor compounds was ethanol. Phytochemical analysis showed that ethanolic extract of endophytic Streptomyces sp. AEBg12 contained flavonoids. IC50 value of ethanol extract was 180.83 g/ml. The result of TLC showed that ethanolic extract of Streptomyces AEBg12 had a blue luminescence band indicated that there were either flavone, flavanones, flavonols or isoflavones. Inhibitory activity of Streptomyces sp. AEBg12 was higher than wild bangle and bangle tissue culture. The information from this study can be be used as a basic data for further characterization of the active compound, which might be developed as an antiobesity agent through its pancreatic lipase inhibitory activity.]]>

<![CDATA[Cassava stalk can be converted into sugar-based product by using microorganism. Unfortunately, lignin act as a barrier of optimal bioconversion. Cassava stalk needs pretreatment process for removing this barrier. The effect of lime pretreatment on microstructure of cassava stalk fibers and the growth of Aspergillus niger FNCC 6114 were observed in this research. The cassava stalks were reduced into 0.147- 0.297 mm size and pretreated with 1 % Ca(OH)2. Lime pretreated and unpretreated cassava stalk was used as solid medium for Aspegillus niger FNCC 6114. The effect of pretreatment method on fibers microstructure of cassava stalk was evaluated through SEM micrograph. The growth and metabolism activities of Aspergillus niger FNCC 6114 were monitored through SEM micrograph of media after fermentation. The other parameters examined were changes in glucosamine, reducing sugar levels, and sporesâ quantity. Lime pretreatment altered microstructure of cassava stalk fibers. However, cassava stalk without lime pretreatment gave better growth of Aspergillus niger FNCC 6144 based on metabolism activities parameters. Cassava stalks is suitable as media for Aspergillus niger FNCC 6144 through solid state fermentation. For better growth of Aspergillus niger FNCC 6144 fine-sized cassava stalk should not be lime pretreated. The results of this study provide information about the pretreatment of cassava stems which was effective in supporting the growth of Aspergillus niger. Enhancements the utilization of cassava stems by using fungi, for example Aspergillus niger can overcome the accumulation of organic waste that can interfere with environmental sustainability.]]>

<![CDATA[Termite are known to infest building in the tropics, but in their quest for cellulose they may also cause signifi cant damage to crops and trees. They become pest only when their natural habitat is altered in some way by humans. Subterranean termite Coptotermes spp has been known as the most economically important structural pest in Indonesia. Due tomorphological ambiguity, traditional identifi cation of Coptotermes spp. has always been diffi cult and unreliable. In economic point of view, economic loss due to termite attack always increases every year, and in the year 2000 it is estimated to reach 373 million US$. Moreover, the social as well as ecological impact caused by termite attack should also be considered. In the capital city of Jakarta, the subterranean termite attack on home buildings reaches around 55%; while in Surabaya (East Java) 36%; and in Semarang (Central Java) 41%. Meanwhile, in some other cities, the subterranean termite attack on home buildings reaches on the average of 20%. The presence of termites in a region can depend on various factors, such as soil and vegetation type. Climatic features andwater avaibility play an important part in termite survival. Daily and seasonal changes in these factors also affect termite distribution.Keywords: characteristics, climatic, Coptotermes spp, attack impact.]]>

<![CDATA[Pseudomonas aeruginosa is an opportunistic bacterium that causes infections in human. The wall cell of its bacteria contains lipopolysaccharide as virulency factors to protect it from human immunity. Lipopolysaccharide can inhibit phagocytosis in the body. Polysaccharide krestin (PSK) from Coriolus versicolor extract contains ?-glucan that can increase phagocytic activity and capacity. This research aimed to identify the effect on polysaccharide krestin from C. versicolor extract on phagocytic activity and capacity of mice exposed by P. aeruginosa. The design of this research was experimental design. There were six treatment groups. The phagocytic activity and capacity were counted on slide smears of mice peritoneal fluid. The data was analyzed by using one way ANOVA. The results of the phagocytic activity and capacity showed that PSK was added before exposure (P1) or after exposure (P2) or before-after exposure (P3) had potential to increase phagocytic activity and capacity. The conclusion of the research was that adding polysaccharide krestin either before exposure or after exposure or both of them could increase phagocytic activity and capacity. The benefits of this research to development of science are expected to reduce human infection and to utilize natural ingredients as immunomodulator.How to CiteWahyuningsih, S. P. A., Savira, N. I.

<![CDATA[AbstrakAntioksidan merupakan senyawa untuk pertahanan tubuh host terhadap radikal bebas. Pada pasien tuberkulosis paru (TB paru), rendahnya antioksidan menyebabkan kerusakan jaringan. Salah satu antioksidan tubuh adalah glutation. Rendahnya glutation berhubungan dengan gangguan sistem imun, sehingga menyebabkan keparahan penyakit pada pasien TB paru. Penelitian ini bertujuan mengetahui kadar glutation plasma penderita tuberkulosis paru. Desain penelitian ini adalah kohort prospektif. Sampel TB paru dipilih di Balai Besar Kesehatan Paru Masyarakat (BBKPM), Makassar yang sesuai dengan kriteria inklusi dan eksklusi dan sesuai kadatangan (consecutive sampling). Dua mililiter darah diambil dari setiap sampel, kemudian dilakukan pemeriksaan kadar glutation dengan ELISA. Hasil penelitian menunjukkan bahwa kadar glutation sampel pasien TB paru sebelum pemberian obat antituberkulosis (OAT) sebesar 0,483830,0344 mM dan setelah pemberian OAT sebesar 0,494650,0371 mM. Setelah pemberian OAT kadar glutation mengalami peningkatan sebesar 2,2% meskipun masih lebih rendah dari kadar glutation normal.AbstractAntioxidants prevent hosts against free radicals. In pulmonary tuberculosis (TB) patients, the low level of antioxidants may cause tissue damage in oxidative hosts. One of antioxidants is glutathione. The poor glutathione level correlates with immune system disorder. The current study aimed to determine glutathione plasma levels in pulmonary tuberculosis patients. The study design was prospective cohort. Pulmonary TB samples were obtained from patients in the Lung Health Centre (BBKPM) in Makassar, and they were selected based on the inclusive and exclusive criteria and on their admittance times (a consecutive sampling technique). Two mililiters of blood was taken from each sample and the glutathione level was examined using ELISA. The study indicated that the glutathione level of the pulmonary TB patients before administered with antitubeculosis drug was 0.483830.0344 mM and after antituberculosis drug was 0.494650.0371 mM. After administration of antituberculosis drug the glutathione level increased by 2.2%, although still lower than normal glutathione level.]]>

<![CDATA[Daemonorops draco has been reported for its antibacterial activity and empirically used for wound healing by Anak Dalam ethnic at Jambi Province, Sumatera-Indonesia. This study was performed to evaluate antibacterial and antibiofilm activity of D. draco resin collected from Jambi. D. draco resin was extracted using n-hexane, ethyl acetate and methanol, respectively. Antibacterial activity of the extracts was evaluated using agar diffusion method against Staphylococcus aureus and Eschericia coli, whereas the minimum inhibitory concentration (MIC) and minimum bacteriacidal concentration (MBC) was determined by microdilution method. In addition, antibiofilm activity was evaluated by violet crystal method. The result showed that extraction yield of ethyl acetate was higher than methanol and n-hexane. Ethyl acetate and methanol extracts of D. draco exhibited stronger antimicrobial activity against S. aureus compare to n-hexane extract. MIC and MBC of methanol extract and chromatographic fraction (F5.1) of ethyl acetate extract were 0.5 and 1.0 mg/mL, respectively. In addition, antibiofilm assay revealed that all extracts were inhibit initial attachment of bacteria cell in biofilm formation. This result revealed a novel information that  D. draco extracts was potential as inhibitor of biofilm formation. TLC bioautography of D. draco extracts indicated that constituent with Rf of 0.71 performed antimicrobial activity against S. aureus. This finding expected to strengthen the scientific backup for utilization of D. draco by society.]]>
