Abstract

Trypanosoma evansi known as trypanosomiasis causes or called surra in animals. Trypanosomiasis-associated death were generally due to severe anemia. Another report mentioned that a rapid death of mice can be attributed to the several reasons. One of those reasons is highly parasitaemia that leads to death of the host. However, there is another distinct report that high parasitemia in mice does not necessarily lead to anemia and clinical symptoms. This research was focused to study the relationship between trypanosomiasis-associated death with haematology profile, particularly the decrease of PCV (packed cell volume) value, anemia and virulence of T. evansi collected from several region of Indonesia. The experiments were performed by dividing mice into four groups. Three groups were infected by T.evansi according to the original isolates while another group were uninfected mice. Every two-day interval, all mice were observed their mortality and parasitaemia and also examined the PCV value and erythrocyte counts in peripheral blood. The experimental results shown that the degree of parasitemia in mice were not always related to mice mortality and anemia. Decreases of PCV value were related to the existence of parasitaemia but not with anemia. This study suggests that there is no relationship between the decreases of PCV value and anemia to the trypanosomiasis-associated death in mice.

Abstract

Ethanol 95% and water extracts of Kaempferia spp. (K. galanga, K. angustifolia, K. pandurata and K. rotunda) were tested for their influences in in-vitro phagocytosis activity and phagocytosis capacity of mouse peritoneum macrophage cells induced by Staphylococcus epidermidis. Extracts were tested at a series concentration in logarithmic order (0.1-1000) ug/ml. Imboost and distilled water were employed as positive and negative controls, respectively. The results shows that almost all extracts were capable to increase on phagocytosis activity (SPA - Screening for Phagocytosis Activity) and phagocytosis capacity (IP • Index Phagocytosis) of macrophage cells compared to positive and negative controls significantly (p<0.05).The phagocytosis activity and capacity macrophage cells were increased by increasing extract concentration. K.rotunda extracts shows reveal better on above activities in low concentration (0.1-100) ug/ml then other species.

Abstract

Sengon buto (Enterolobium cyclocarpum Griseb) is one of the potential plant species for land reclamation and possibly for phytoremediation because of its fast growing even on poor soil, and its ability to fertilize soil through nitrogen fixation. For phytoremediation purpose we need fast growing plant with high ability to absorp target contaminant. Fertilization is needed to improve plant growth. This experiment was carried out to study the tolerance of sengon buto (Enterolobium cyclocarpum Griseb) grown on cyanide contaminated tailing media on various level of NPK fertilizer.The sengon buto seed were planted in the tailing of gold mine media mixed with compost (4:1) in pots. Various levels of NPK fertilizer were applied i.e. 0, 2, 4, 6, 8 g/pot at 2 and 2.5 month after planting (MAP).The plant were harvested at 6 MAP. The result showed that NPK fertilizer increase plant growth at level 2 of 2 g/pot, however the value of the increment was not significantly different with control plant (0 g/pot). Cyanide content of NPK treated plants were higher than the untreated plants. The highest value of shoot/root cyanide content ratio was on the NPK untreated plants (4.34) followed by 2 g/pot treatment (3.59). It is means that sengon buto is potential for phytoremediation of tailing of gold mining.

Abstract

Marine actinomycetes were isolated from mangrove sediment from the coast in Enggano, Bengkulu Province, Indonesia using the medium NBRC No. 802 modified by the addition of 2% NaCl. A total of 29 isolates of actinomycetes were isolated from three mangrove sediment samples and evaluated their potential to produce bioactive metabolites. Screening of 29 isolates marine actinomycetes isolates were performed against three bacterial pathogens had been done. Bacteria test used was Escherichia coli NBRC 14 237, Staphylococcus aureus NBRC13 276, and Bacillus subtilis NBRC 3134. Screening result showed that seven isolates have inhibitory effects against bacteria test and 22 other isolates have no inhibition. Of the seven isolates, one isolate has inhibitory effect against the growth of Gram-negative bacteria Escherichia coli, while six other isolates inhibit Gram-positive bacteria Bacillus subtilis and Staphilococcus aureus. It was concluded that, of the 29 isolates conducted in the experiment, seven isolates produce antibacterial compounds on agar medium. Molecular identification of 23 isolates were identified based on  the gene 16S RNA sequences showed that 22 isolates belong to the genus Streptomyces and one strain belongs to the genus Dermacoccus.

Abstract

Berbagai stigma diberikan untuk cendana (Santalum album L.) berhubungan dengan status dan perlakuan terhadap komoditi tersebut, seperti kayu setan (hau nitu), kayu perkara (hau lasi) dan kayu pemerintah (hau plenat). Penghitungan terhadap produksi cendana dalam kurun waktu 28 tahun (1969-1997) cukup fluktuatif, dengan rataan sebesar 606.000 kg per tahun. Sementara nilai jualnya bervariasi, tergantung dari klasifikasi kayu, yaitu antara Rp. 1.000 (untuk gubal) hingga Rp. 118.000 (untuk kelas A). Perdagangan tersebut telah memberikan kontribusi kepada PAD (Pendapatan Asli Daerah) NTT dalam kurun waktu 8 tahun (1990-1998) dengan rataan sebesar Rp. 4.071.000.000 setiap tahun. Mengingat perdagangan cendana memiliki nilai ekonomi, baik bagi Pemerintah Daerah, masyarakat maupun industri/pedagang cendana, maka diperlukan pokok-pokok pikiran strategis bagi pengembangan dan pengelolaan cendana di masa mendatang.

Abstract

The effect of cryoprotectants glycerol and sucrose on cell viability and fermentation rate of Saccharomyces cerevisiae after freezing (-30 °C) and Chawing (30 °C) were studied.Both freezing and thawing were done rapidly. The mortality of cells treated with low concentrations of cryoprotectans (2.5, 5, and 10 %) after 15 and 30 days of cryopreservation, was remarkably higher than that of control and higher concentration (20% and 40%).Glycerol or sucrose with concentration of 20 % and 40 % protected cells from severe mortality only after 90 days of cryopreservation.Fermentation rate of cells treated with 20 % or 40 % of the two cryoprotectants were higher than that of control after 60 and 90 days of cryopreservation.The data indicated that in certain circumstance cryoprotectant could be toxic for the cells during freezing and thawing.Since biomembrane is not permeable to sucrose, therefore we proposed that target of sucrose toxicity may be extracellular, whereas glycerol, which penetrate cells,targets of the toxicity may be both extracellular and intracellular domains.Interaction between cryoprotectant and cell membranes is discussed.

Abstract

Spodoptera exigua Huebner nucleopolyhedrovirus (SeNPV) is an entomophathogenic virus of onion caterpillar S. exigua larvae commonly used as bioinsecticide. The major limitations of SeNPV for biocontrol of onion caterpillar is it requires long time for the virus to kill the insect host. This research was aimed to find out the material as phagostimulant to increase the infectivity of SeNPV and to determine the optimum boric acid concentration as an enhancer for SeNPV activities. This research was conducted at laboratory using Cipanas isolate of SeNPV and third instar of S. exigua larvae. Phagostimulant used are 5% ofsucrose, soybean sauces, molases, sugar and turmeric filtrate,and the enhancers used are 0,1%, 1%, 5% and 10% concentration of boric acid. This result indicated that soybean sauces and sucrose increased S. exigua consumption and enhanced the infectivity of SeNPV. When mixed with polyhedra of SeNPV, 1% to 5% sucrose significantly increased S. exigua consumption and increased the infectivity of SeNPV, while 10% sucrose tended to decrease the feeding of S. exigua. Boric acid enhanced the infectivity of SeNPV. However, the increase of boric acid concentration should be restricted maximum at 5% for avoiding the negative impacts on the environment.
