Abstract

The aim of the research is to obtain the ecological condition and propagation of kamandrah (Croton tiglium L.) and determination of its potency as biological larvacidal for preventing dengue haemorraghic fever. Agrobiophysic study indicated that Croton tiglium L. plant need full sunlight(> 70 %). low intensity of sunlight could decrease the ability of plant to produce seed. The plant could grow well on podzolic land (30-50 m upon sea surface). Seed of kamandrah from Ampah has growth percentage of 43.8 °/o, height of 27.5 em, stem diameter of 5 em, total leaves of 10, and total primary branches of 2. Phytochemical assay resulted that among other part of Kamandrah, Kamandrah seed has highest alkaloid content. Because alkaloid compound has high larvicidal activity, kamandrah seed has high potency as larvicide. Among all of extracts of part of plant, oil of Croton tiglium L. has the highest potency as biological larvacidal with 863.67 ppm of LC50 for 24 hours of treatment.Keywords : Kamandrah (Croton tiglium L.), biological larvacidal, Dengue Haemorraghic fever, agrobiphysicstudy.

Abstract

Recently, Indonesia has big problem caused by dengue haemorraghic fever with A. aegypti as vector. Potential medicine and vaccine for curing this disease have not been found. The effective method to prevent this disease is the use of A. aegypti larvicidal. The chemical larvicidal has disadvantage for evironmental aspect. To solve this problem, the biological larvicidal has a good chance to develop. Indonesia has megadiversity which can be developed as biological larvicidal. Crude aqueous extracts and ethanol extracts of Jatropha curcas (Jarak pagar) seed and oil of Jatropha curcas were evaluated for larvicidal potential against the Aedes aegypti mosquito. Among all extracts, Jatropha curcas oil possessed a highest activity against the 3th instar larvae of Aedes. LC50 values of Jatropha curcas oil was 1507 ppm for 24 h and 866 ppm for 48 h. It was suggested that the Croton tiglium oil and Jatropha curcas oil possess larvicidal properties that could be developed and used as biological larvicidal. Keywords: Jatropha curcas, oil, Aedes aegypti, biological larvicidal, dengue  haemorraghic fever.

Abstract

The aim of the study was to analyze the potency of Centella asiatica extract to induce proliferation andneurogenesis process of newborn rats cortex cerebri.   Research has been conducted on in vitro culture ofthree days old rat (Sprague Dawley) cerebrum cells in DMEM (Dulbecco’s Modiûed Eagle’s Medium)containing 10% NEAA (Non Essential Amino Acid), 1 mM NaHCO3, 10% NBCS (Newborn Calf Serum)and 50 µg/mL gentamycin (mDMEM), with and without Centella asiatica (CA) leaf extracts. The experimentwas set in five groups of treatment consisted of positive control (mDMEM+30 µg/mL asiaticoside (AC)),negative control (mDMEM), and mDMEM with three concentration of CA extract i.e. 100 ppm, 200 ppmand 400 ppm. Culture was done in 5% CO2 incubator at 37oC for six days. The parameters observed werecells proliferation based on Population Doubling Time (PDT), neuron and glia composition, and the lengthof axon and dendrite. Cells concentration were counted using Newbauer hemocytometer.  Neuron and gliacells were determined based on morphology after Hematoxylin-Eosin staining, and the length of axon anddendrite were measured using eyepiece micrometer. Data were analyzed using ANOVA and Duncan test.The results showed that Centella asiatica extract at concentration 100 ppm could induce neurogenesisand increased the axon length growth.  However, at concentration 200 and 400 ppm, CA extract  inhibitedthe neuronal cells proliferation and the axonal growth (P<0,05). In conclusion, induction of Centella asiaticaextracts at concentration of 100 ppm on the cortex cell cerebrum cells culture increase the axon lengthgrowth and tends to induce neurogenesis; however at higher concentration CA extract was neurotoxic.

Abstract

Coxiella burnetii belongs to rikettsia group living obligate intracellularly and as the agent of zoonosisQ fever. Enrofloxacine is an antibiotic in quinolon group used to treat infection of C. burnetii in chicken,goat, calve, pig, dog, cat,  and horse. From ruminant practical experience, enrofloxacine if combined withBioATP  can enhance the enrofloxacine activity. Research for the effecivity of enrofloxacine and BioATP totreat C. burnetii has never been carried out. The research was conducted to explore effect of enrofloxacinewith supplementation BioATP against C. burnetii. Enrofloxacine pharmacokinetic study was carried outby using simental beef as an experimental animals. The effectivity of BioATP supplementation onenrofloxacine activity to treat C. burnetii was tested by using Vero cell tissue culture. The results showedthat combination of enrofloxacine and BioATP increased kinetic profile of enrofloxacine in term of onset,duration, pharmacology intensity, and bioavailaibility. Enrofloxacine had activity to treat C. burnetii withvalue of minimal inhibitory concentration (MIC) at 1-2 ppm and value of minimal bactericidal concentrationat 4 ppm. Supplementation of BioATP improved the effectivity of enrofloxacine in treating C. burnetii.

Abstract

Background: Nonsteroidal anti-inflammatory drugs (NSAIDs) gastropathy is a common complication, which has characteristic symptoms of dyspepsia syndrome. Mostly, it includes epigastric discomfort with bloating and nausea. The aim of this study was to provide evidences that clinical symptoms of dyspepsia are related to macroscopic changes of gastric form in rats, which are expected to be applied in human. Method: The study was conducted in 20 white rats (Rattus norvegicus, Sprague-Dawley strain) at the Department of Pathology and Clinical Reproduction, Bogor Agricultural University between January and December 2008. The rats were divided to treatment group and control group and each group consisted of 10 rats. Acetyl salicylic acid (ASA/aspirin) was administered at 400 mg dose, diluted in distilled water and was given to the treatment group using gastric cannula, once daily for three days period; while the control group had received aquabidest only. Subsequently, necropsies were conducted for both groups, followed by macroscopic observation and measurement of sagittal and transversal diameter. Gastric incisions along the minor curvature were performed in both groups to recognize any macroscopic changes of gastric mucosa. ANOVA test was utilized for data analysis, which was followed by Duncan test when the results were significant. Results: Gastric diameters in treatment group with positive lesion were significantly different from the control group and the treatment group with negative lesion on anthrum/pylorus region, with p < 0.05. Conclusion: Prominent gastric dilatation at anthrum/pylorus region found in the treatment group may become the initial cause and signs of dyspepsia in human. Keywords: NSAID gastropathy, dyspepsia, NSAIDs/aspirin, gastric dilatation

Abstract

Background: Mucus is pre-epithelial gastric layer that may prevent damages due to direct contact between aspirin and gastric epithelial cells. The integrity of gastric mucosa and mucous cellular reaction may serve as primary and secondary prevention of extended aspirin-induced gastric mucosal damage. The aim of this study was to prove the function of mucus as defensive factor in rats. Method: The study was conducted in twenty white rats of the Sprague-Dawley strain at Department of Pathology and Clinical Reproduction, Bogor Agricultural University, between January and December 2008. The rat in the treatment group were given 400 mg aspirin diluted in aqua bidest through intra- gatric canules; while the control group received aqua bidest only once daily for 3 days. Necropsies, macroscopic and microscopic observation were performed by counting the number of Alcian blue- periodic acid Schiff-stained mucous cells at fundus/corpus and antrum/pylorus regions. Data analysis was performed using ANOVA and Duncan test. Results: The number of mucous cells with positive lesions in the treatment group was significantly different from the control group at both regions. There was no significant difference of negative lesions between treatment and control group at both regions. At antrum/pylorus region, there was no difference of negative lesions between treatment and control groups; however, both groups demonstrated significant difference of positive lesions in treatment group. Conclusion: In primary prevention for gastric mucosal lesions, there is no increasing number of mucous cells in normal mucosa. Increasing number of mucous cells is a secondary prevention against extended aspirin-induced gastric mucosal damage. Keywords: NSAIDs/ASA, mucus cells, gastric mucosal lesion, rat
