Abstract

Research on the influence of isoniazid on rifampicin metabolism using rat hepatocytes has been done. As the system metabolism, hepatocytes suspension was prepared by perfusion in the calcium binding media containing EDTA, citrate and glycine was used. In the experiment, combination of rifampicin and INH on various doses was incubated in those metabolism system at 30oC from 0 and up to 180 minutes duration. Then, analysis was done by thin layer chromathography and densitomeric method for each incubation intervals. Result calculated on the base of variation of rifampicin AUC-value beginning from 0 up to 180 minutes showed that isoniazid with concentration 5 µl, 10 µl, 15 µl, and 20 µl did not influence the metabolism of rifampicin (10 µl/ml) as showed by no significance changes of AUC value of rifampicin for α = 0.05.

Abstract

The rearing technology of green catfish larvae has not yet established. Hight mortality occurred in the early larval stages. This experiment was conducted to study the effect of temperature and dissolved oxygen on metabolic rate and survival rate of green catfish larvae. 3600 green catfish larvae with initial individual mean weights of 1.24 ±0.19 mg and lengths 5.85 ±0.71 mm (one day after hatching) were reared in the aquarium of 30 cm x 30 cm x 40 cm dimension. Treatments were done at 3 levels of temperature 27oC, 30oC, and 33oC; and 3 levels of dissolved oxygen 6.47 ml/L, 1.05 ml/L, and 0.78 ml/L and 3 replications. The result showed that temperature and dissolved oxygen was significant to the oxygen consumption. Oxygen consumption of 0.67 ±0.25 mg O2/h/g and 0.86 ±0.005 mg O2/h/g was highest in larval reared at 33oC and dissolved oxygen 6.47 ml/L for 3 weeks. The higher water temperature the greater the oxygen consumption. The oxygen consumption decline with decreasing dissolved oxygen in the water, indicating an axyconformer type. The temperature was not significant to the survival rate and growth of the larvae. However the effect of dissolved oxygen was significant to the growth rate (P<0.05). Growth rate of 25.69 ±0.55% was highest in larval reared at 6.47 mg/L for 3 weeks.

Abstract

SpherefixTM bioinsecticide is microbial agent of Bacillus sphaericus H-5a5b (VCRC B24) showing high potency for vector control. The bioinsecticide specific to target insect, and do not produce any adverse environmental impact, so the bioinsecticide would be very promising agent for vector control, especially vector of dengue haemorrhagic fever in Indonesia. The present studies aimed at observing the toxicity persistence of SpherefixTM on the larvae Aedesaegypti L. in some types of water container, and recycling potencies in the breeding places of A.aegypti. Two steps of the studies were carried out under laboratory conditions. Firststeps were reared mosquitos in the laboratory to supply larvae of Aedes aegypti. Second step testing of SpherefixTM toxicity persistence in the cemented, clay, and plastic containiers. The bioinsecticides were preparated by Vector Control Research Centre (VCRC), India. The toxicity persistence of SpherefixTM on the larvae of A. aegypti L. in some types of water container were decided by probit analysis. The toxicity persistence tests were carried out by time series observation on the day 1, 6, 12,,,, and 120. The result showed that difference toxicity persistence of the SpherefixTM in the breeding places of A. aegypti. The cemented container was found to have longest of toxicity persistence of the SpherefixTM followed by the plastic container, and the clay container ha the shortest duration toxicity persistence. The higher concentration of the boinsecticides, will result in higher toxicity persistence. The SpherefixTM showed recycling potency in the breeding places of A. aegypti. Percent motility of the larvae dropped sharply after day 50, and larvae mortality under 5% after day 78.

Abstract

The influence of benzopyrene exposure on the decrease of humoral immune response in ileum of mice, was studied to demonstrate the reduction of immunocompetent cell components that may decrease mucosal immune response, especially decrease of active plasma cells in the ileum of mice exposure benzopyrene in different dose, exposure period, and combination of dose and exposure period. This study used 36 mice, which were divided into three dose group (0, 10, and 20 mg/kg BW). Each dose group was subdivided into 4 different period groups (1, 2, 4, and 8 weeks). In control group, olivarum oil was given orally to each mice, while in the treatment groups, benzopyrene solution of 10 mg/kg BW (P1) and 20 mg/kg BW (P2) as much as 0.2 ml was given orally to each mice during the determinant periods. Result showed that variables active plasma cells, period factor were not significantly different, while dose factor and combination of dose and period were significant different.

Abstract

The aim of this research was identifying the stimulation serum protein synthesis following the treatment of Java Gingseng (Talinum paniculatum Gaertn) root extract in varying concentration. This research used 12 male rats of 8-9 weeks, divided into 4 groups. First group as control, second group to five group were administratered with Java gingseng root extract equal with 3.5, 10.5, and 21 mg dry roots / 100g BW / day per oral for 14 days. Blood serum was collected for electrophoresized at the end of treatment. Electrophoresis was conducted with 7% SDS-PAGE method. Gel stained in 0.25% Coomasie Brilliant Blue and it followed densitometry on band in gel to comparing those quantitatively. The result show the effect on the level of serum protein whose MW 29. Highest stimulation of protein synthesis (2.2 times than control) have been reached at treatment with extract that equal with 3,5 mg dry root/ 100 g BW/ day. Increasing Java gingseng root extract wasn’t followed by increasing of stimulation protein synthesis level.
