Abstract

‘Tempe’ is a popular Javanese-Indonesian tradisional food made of fermentedsoyabean. This study aims to examine whether ‘tempe’, used as a strong anti-free,has the ability to decrease DNA damage induced by ultraviolet ray irirradiation inthe Wistar rats as indicated by the levels of urinary 8-hydroxy-2-deoxyguanosine.A Total of 24 Wistar rats, 2.5 to 3 mounths and 200 gr body weight, weredividing into 4 groups of equal size i.e. three treatment and one control groups.All rats were exposed to 5-hours daily UV ray sources of UV 15 watt Philip for 60days. Randomized post test only control group design was used in this study withindependent variables of 0, 1, 2 and 3 g ‘tempe’ per kilogram body weight per dayand independent variables of 8-hydroxy-2-deoxyguanosine urinary level as aDNA damage biomarker following an oxidative stress. Data were analyzed byusing one way ANOVA followed by Tukey HSD.The results of our study indicates that there is a decrease of DNA damageis manifested by progressive decrease of 8-hydroxy-2-deoxyguanosine level in thetreatment groups as compared to the control group. Statistically significantdecrease of 22.61 % and 25.62 % was shown with p > 0.05.From our analysed data is could be inferred that ‘tempe’ has the ability todecrease DNA damage caused by ultraviolet ray irradiation. Supplementation of2 g ‘tempe’ per kilogram body weight per day appeared to have the strongesteffect of decreasing DNA damage in Wistar rats.

Abstract

ABSTRACT Exclusive breastfeeding reduces the incidence of diarrhea, especially in children who live in densely populated neighborhood. This study aims to determine the relationship between exclusive breastfeeding and breast milk contains antirotavirus s-IgA antibodies towards risk of acute rotavirus diarrhea in infants aged of 1-6 months. Case-control study design is applied to determine the relationship between exclusive breastfeeding and breast milk contains s-IgA antibodies antirotavirus with risk of acute rotavirus diarrhea. Cases in this study were patients with acute rotavirus diarrhea and controls were patients without acute rotavirus diarrhea. Cases and controls were matched based on age. There were 23 cases and 69 controls. The proportion who received exclusive breastfeeding was 34.8% in cases and 34.4% in controls, with OR of 1.21 (95% CI: 0.45 to 3.28) and p = 0.28. Breast milk contains sIgA antibodies antirotavirus for case was 17.39% and controls was 23.2%, OR was 1.12 (95% CI: 0.29 to 4.29), p = 0.203. In conclusion, exclusive breastfeeding and breast milk contains sIgA antibodies antirotavirus were not associated with risk of acute rotavirus diarrhea in infants 1-6 months. This may be caused by differences in population and demographic studies as well as low of milk sIgA antibody antirotavirus titters. Further research of breastfeeding regardless of antirotavirus containing high antibody titters sIgA is needed.

Abstract

Caulerpa spp. including seaweed and macro-algae can be found in a large number at Coastal Serangan, Bali-Indonesia. Caulerpa spp was historically used for food and vegetable. However, in our today life, this plant was applied as material for skin care products, especially for UV protection. The aim of this study is to know the active component of caulerpa spp extract and its inhibition of premature skin aging induced by UV-B radiation through collagen expression. This was descriptive and experimental research applying a randomized posttest only control group design. Active component contained in the caulerpa spp extract are carotenoid, vitamin A, C, and E, polyphenols, minerals and amino acids. Topical application of caulerpa spp can suppress the UV-B radiation induced collagen damage. Increased of collagen expression in all groups of caulerpa spp. just as good as astaxanthin group in improving collagen expression and 0.2% of caulerpa spp. extract is the most effective dose in improving collagen expression.

Abstract

This research aimed to amplify a 1700 bp fragment of rpoB gene of multidrug resistance M. tuberculosis (MDR-TB) isolate and determine types of mutation beyond the core region (hot-spot region). DNA sequencing studies indicate that more than 95% of rifampin-resistant M. tuberculosis strains have mutations within the 81-bp hot-spot region (codons 507 to 533) of the RNA polymerase ?-subunit (rpoB). Since almost 90 % of rifampicin resistant isolate are also resistant to isoniazid, mutation in rpoB gene become important as a surrogate marker for MDR-TB. MDR- TB isolates used for this research, namely isolate 885, was collected by Regional Health Laboratory of Surabaya. PCR was used to amplify the gene, on described steps : a cycle of preheating at 95°C for 15 minutes, amplifying in 45 cycles ( 1 minute at 94°C, 1 minute at 58°C, 1 minute 72°C) and post extension for 5 minutes at 72°C. The mutations were detected by sequencing and alignment using MEGA4. The result of this research showed that there were new mutations downstream of the core region of rpoB. Sequence analysis showed some mutations such as S594A, S626V, T629A. In conclusion, it is reported for the first time, new mutations at downstream region of the core region of rpoB.

Abstract

Hypercholesterolemia or hyperlipidemia has been established as an important risk factor of cardiovascular disease. Patients with hypercholesterolemia usually require a prolonged treatment; and the newer and more potent generation of antilipid agents are costly.In Bali there are several types of seaweed that are generally consumed by the local people and known by the local names of Bulung Boni (Caulerpa spp.) and Bulung Sangu (Gracilaria spp.). Preliminary studies on the effect of Bulung Boni and Bulung Sangu extracts appeared to improve lipid profile, but the available data are still very limited both in extent and depth, and further investigations were considered relevant and needed.This experimental study used completely blind randomized design, using a total of 24 Wistar rats divided into six sample groups of equal size, all fed with a diet high in cholesterol content. The six sample groups were respectively designated as negative control group, positive control group, and four treated sample groups, respectively fed orally with a dose of 20 mg and 60 mg extracts of Bulung Boni per 100g of body weight per day, and 20 mg and 60 mg extracts of Bulung Sangu per 100g body weight per day. Each treatment was repeated four times.Our study showed that rats fed with high-cholesterol diet and treated with oral Bulung Boni or Bulung Sangu extract at a dose of 20 mg and 60 mg/100 g bw/ day were associated with statistically significantly increased plasma HDL levels (p < 0.05), and statistically significant decreased plasma LDL and total cholesterol levels (p < 0.05) as compared with those of rats fed with high cholesterol diet without treatment with Bulung Boni or Bulung Sangu extracts.From our data it could be implied that Bulung Boni and Bulung Sangu extracts improve lipid profile in the Wiatar rat by significantly increasing plasma HDL level, and lowering LDL and total cholesterol levels.
