Objective: The aim of this study was to investigate the effect of hydrolyzed oils of different fatty acids composition on swimming capacity of mice.Methods:The oils used were Virgin Coconut oil (VCO) and Palm Kernel oil (PKO) as medium chain triglyceride (MCT) oils, Palm oil and Corn oil as long chain triglyceride (LCT) oils. Hydrolysis of the oil was performed with Rhizomucor miehei lipase enzyme. The mice were acclimatized and tested motoric to select the mice and divided into twenty groups, each group consisted of 5 mice. Each oil in the experiment were 0.1 ml, 0.2 ml, 0.4 ml/ 20 g BW, positive control was caffeine 13 mg/kg bw. Then, the mice were placed in a glass aquarium. Then swimming capacty endurance was measured.Results:.Non-hydrolyzed oils with dose of 0.1ml significantly induced swimming capacity of mice compared with negative control (distilled water) from 184.8 increased to 248.0 seconds by MCT oil, to 239.8 seconds by unsaturated LCT oil and to 214.8 seconds by saturated LCT oil. The hydrolyzed oils increased swimming capacity ± 65% by hydrolyzed MCT oils, ±54% by hydrolyzed unsaturated LCT oil and 21% by hydrolyzed saturated LCT oil. The hydrolyzed corn oil at high dose (0.4ml) was more effective to increase swimming capacity than saturated MCT (VCO and PKO) and LCT oil (palm oil).Conclusion:The results suggest that hydrolyzed MCT and LCT oils are more effective to increase swimming capacity than non-hydrolyzed.
BACKGROUND: Many researchers have been indicated that premature hair greying (PHG) may be associated with the multifactorial problem include genetic, trace elements deficiencies and some medical problems such as metabolic disorders. However, the risk factors for premature hair greying are not well known for young adult. AIM: This study aimed to determine the risk factors of hair greying in young adult. METHODS: We conducted a cross-sectional study recruited 100 respondents of a college student at the Universitas Sumatera Utara (USU) with the inclusion criteria: male, less than 25 years old with hair greying and not have skin pigmentation disorders. The questionnaires about greying of hair status, family history of greying and history of family disease were collected by self-report. RESULTS: The age of participants in this study was 20.09 ± 2.01 years (mean ± SD). The mean onset of PHG was 15.23 ± 3.52 years (range: 9 – 22 years). The family history of PHG was 39% with paternal in 262%; maternal in 10%% and both parents in 3%. There was a significant difference between several grey hairs with a family history of PHG P = 0.045. The family history with metabolic disorders; hypertension was 29%, obesity was 25%, and diabetes Mellitus (DM) was 15%. Limitations: Owing to the use of questionnaires, the possibility of recall bias exists. The young female was not evaluated in this study. CONCLUSION: The family history of PHG and onset of greying are important risk factors associated with PHG of a young adult.
Breast cancer was the second most common cancer that causes death in women worldwide. One ingredients of herbal plants as an alternative therapy in the community, was gambir leaves. This research was conducted to examine the anticancer activity of Uncaria gambir Roxb on T47D breast cancer cells in vitro. Six levels of concentration U. gambir (31.25 mg/ml up to 1000 mg/ml) was included on the 96 microplate well which had been filled with breast cancer cells, the positive control was doxorubicin (with concentration of 0.03-1 mg/ml). The anticancer effects of U.gambir was determined by MTT (3-[4,5-dimethylthiazol-2-yl]- diphenyl tetrazolium bromide 2.5). The results showed the existence of anticancer activity of Uncaria gambir Roxb at concentrations of 250, 500 and 1000 μg/ml. The largest anticancer activity found at a concentration of 500 μg/ml with the percentage of apoptotic cells of breast cancer by 20%, but we also found a decrease in the value of the apoptotic at concentration of 1000 μg/ml. The IC50 of U.gambir was 1.086 μg/ml whereas the IC50 doxorubicin was 0.108 μg/ml. This study concluded that the inhibition of breast cancer cell growth by gambir leaves extract was still quite weak compared to doxorubicin.
Background: An aqueous extract (AE) of vinegar made from Nypa fruticans Wurmb. can improve postprandial glucose levels in normoglycaemic rats. The aim of this study was to evaluate its antihyperglycaemic activity further using in vivo and in vitro approaches. Methods: AE was administered to streptozotocin (STZ)-induced diabetic rats twice daily at three doses (1000, 500, and 250 mg/kg b.w.) for 12 days p.o. Several biochemical analyses and a histological study of the pancreas and liver were performed, accompanied by a cell culture assay. Results: As compared to diabetic control (DC), AE at the doses of 500 and 1000 mg/kg b.w. caused significant reduction (p < 0.05) of blood glucose, total cholesterol and triglycerides levels, with positive improvement of serum insulin levels. Interestingly, immunohistochemical staining of the pancreas suggested no β-cell regeneration, despite significant increase in insulin production. AE-treated groups, however, showed overall restoration of the hepatic histoarchitecture of STZ-induced liver damage, suggesting a possible hepatoprotective effect. The pancreatic effect of AE was further studied through RIN-5F cell culture, which revealed a positive stimulatory effect on insulin release at a basal glucose concentration (1.1 mM). Conclusion: Nypa fruticans Wurmb. vinegar’s aqueous extract exerts its antihyperglycaemic activity, at least in part, through insulin stimulatory and hepatoprotective effects.
Abstract.Has become a global issue that the increase in global warming mainly caused by high air pollution levels which are donated by motor vehicle emissions. As a rapidly developing country, Indonesia becomes vulnerable to health problems related to air pollution. Excessive free radicals that is produced by air pollution can initiate stress oxidative. Already known that, stress oxidative trigger many health problems. Vitamin C and E is a non enzymatic antioxidant that can neutralize free radicals. This study aims to investigate the decreasing free radicals level by administering vitamin C and E. This research using pre and post experimental design study. There are 24 operators gasoline station Pertamina as samples, with an average age of 26 years. The samples were divided into 4 groups. Group 1 (control), group 2, were given vitamin C doses of 500mg / day, group 3 was given vitamin E doses of 250 IU / day and the group 4 was given a combination of vitamins C and E. The treatment was given for 30 days. Free radicals level is obtained from malonaldehyde (MDA) level by spectrophotometer. Before treatment the average of MDA level is 5.540 µm. After the treatment, MDA is significantly decreased become 3.992 µm (T-test, sig<0.05). This result can be used as a sign of side affect of air pollutant in the operator SPBU. As reminding to protect the employee with safety aid and supplement.
