Abstract

The traditional Balinese richly spiced swine-grill (Babi-guling) has been increasingly popular even among both the domestic and foreign tourists. The traditional grill is very unique in taste as it contains two main components, i.e. the pork and the unique Balinese spices, which probably could work antagonistically one against the other in affecting people health. The pork because of its rich content of saturated fatty acid is a risk of atherosclerosis, while the spices appear to be rich in antioxidatns. This is a preliminary atherosclerosis experimental study designed to screen qualitatively the phytochemical contents of the spices and to test their antioxidant activity and strength in different concentrations in vitro. The methods used included Willstater test, NaOH 10% test, Meyer test, Leiberman-Burchard test, test for saponin, and test for phenol. The antioxidant activity was estimated by using DPPH (2,2-diphenyl-1-pricrylhydrazyl) test. The treatment applied to the spice before testing was raw and cooked by heating it inside the pig’s body cavity. The concentrations of spices tested were 100, 1000 and 8000 ppm. The results of our study revealed that the phytochemical content of the spices were flavonoids, terpenoids and phenolic compounds, but saponin and alkaloids were not detected. The antioxidant activity was ineffective in concentration of 100 ppm (percentage of reduction < 50%), effective in concentration of 1000 ppm (percentage of reduction 50-60%), and too thick in concentration of 8000 ppm (percentage of reduction >100%. We inferred that the traditional Balinese richly spiced swine-grill contains flavanoids, terpenoids and phenol which can act as antioxidants in vitro, and the most effective concentrations to decrease the free radicals were between 1000-8000 ppm.

Abstract

This research aimed to identify the antioxidant capacity, vitamin C (ascorbic acid), and total phenolic compounds of frangipani flower powder. The powder was extracted using ethanol, methanol, acetic acid, and water (aquadest). Antioxidant capacity of each extract were determined using 2,2-diphenyl-1-picrylhydrazyl radical scavenging method, vitamin C were determined using 2,4 Dinitrophenylhydrazine, and total phenolic compounds were determined using Folin Ciocalteu reagent. All of parameters were measured by spectrofotometer. The result shows that the highest value of antioxidant capacity was ethanolic extract (18.19%) and the lowest value was acetic acid extract (12.74%). The highest value of vitamin C was aqueous extract (3.49 mg/100g) and the lowest value was acetic acid extract (3.02 mg/100g). The highest value of total phenolic content was aqueous extract (25.49 mg GAE/g) and the lowest value was acetic acid extract (22.74 mg GAE/g). In conclusion, the higher antioxidant capacity was not always followed by the higher of vitamin C and total phenolic compounds.

Abstract

This study was conducted at the relatively young public junior secondary school at the district of Abiansemal and Administrative Region of Badung (SMPN-3) now aspiring to obtain national accreditation. In this context, the need was felt for improving the teaching-learning environment particularly in the school’s classrooms which might be conducive to maximizing the educational input and student performance. We studied the impacts of applying basic ergonomic principles to the design of some physical facilities (including redesign of the tables and chairs) in the classroom aiming to remediate present perceived deficiencies. Our samples were selected by using the multistage simple random sampling technique; and a total of 81 subjects consisting of 43 male and 38 female, volunteer students were recruited. The statistical methods used include descriptive statistics, analysis of normality and comparability. Our findings implied that interior ergonomic design intervention has led to the following outcomes: enhancing the student performance by decreasing eye strain by 44.76%; musculoskeletal complaints by 50.98%; and boredom by 14.17%. The beneficial outcomes of our intervention appeared to be obvious.
ORAL INTAKE OF SARDINELLA LONGICEPS OIL THE DECREASE OF TNF-? AND IL-6 LEVELS IN ATHEROSCLEROTIC WISTAR RAT Wahjuni, S.; Sudewa, A.A.G.; Wita, I Wayan; Astawa, I.N. Mantik

Abstract

Lifestyle changes to consumption of variegated instant food may be associated several heath hazards, such as obesity, dyslipidemia, and atheroschlerosis. This study was conducted to investigate the effects of orally administered Sardinella longiceps oil as an anti inflammatory agent on the serum levels of TNF-? and IL-6 considered as biomarkers for atherosclerosis.The study design is an true experimental with randomized pretest and posttest control group design, using 50 Wistar rat equaly divided into 5 groups, i.e. placebo control group 0% and 4 treatment groups each treated daily with 10%, 15 %, 20 % and 25 % fish oil respectively for 6 weeks. Before the treatment was started, all rats were orally fed daily with a high cholesterol diet for 13 weeks to induce atherosclerosis. Our study showed that the intake of 20% fish oil had resulted in the significantly greatest decrease of 45,63 % in the TNF-? serum levels,from 28.62 ± 1.25 to 15.56 ± 7.20 ?g/mL and similar significant decrease 15,42% in of IL-6 serum levels from 134.64 ± 1.98 to 113.87 ± 4.30 ?g/mL. The overall results of our study seemed to imply than in the Wistar rats, oral intake of Sardfinella longiceps oils signifacantly decreased serum levels of TNF-? and IL-6 probably through their anti-inflamatory effects. Futher research to determin the magnitude of effects sardinella longiceps oils on the serum levels TNF-? and IL-6 human.

Abstract

Pregnancy is a vulnerable condition to all kinds of "stress", resulting in changes of physiological and metabolic functions. This research aims to determine effect of exercise during pregnancy in reducing oxidative demage marked by decrease of malondialdehyde and 8-hydroxy-diguanosine levels. Randomized pre and posttest control group design was employed in this study. A number of 66 pregnant women were recruited in this study and grouped to two groups, i.e 30 of them as control group and the rest as treatment group. Pregnancy exercise was performed to all 36 pregnant women from 20 weeks gestation on treatment group. The exercise was performed in the morning for about 30 minutes, twice a weeks. On the other hand, daily activities was sugested for control group. Student’s t-test was then applied to determine the mean different of treatment and control group with 5 % of significant value. This study reveals that there were significantly higher decrease of (MDA) and 8-OHdG about 0.15 nmol/ml and 0.08 ng/ml, respectively, amongs treatment and control groups (p < 0.05). Clinical outcomes, such as strengten of pelvic muscle and quality of life of treatment group were significantly better compared to control group (p < 0.05). This means that exercise during pregnancy ages of 20 weeks decrease MDA and 8-OHdG levels higher compare to control group without exercise.

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.
