High blood cholesterol level can cause atherosclerosis which is potentially cause coronary heart disease. Pindang patin is one of the favourite foods in Palembang which contain omega 3 fatty acids that can decrease blood cholesterol level. The aim of this study was to see the effect of pindang patin intake on total cholesterol and LDL. The type of this study was laboratory experimental using a pre-post-test randomized design with a control group in male mice (Mus musculus L.). The mice were given the high-fat diet by using egg yolk as much as 20% of body weight. The samples were divided into 5 groups: Negative Control, Positive Control, Dose I (0.26 ml/20 grams of body weight), Dose II (0.52 ml/20 grams of body weight) and Dose III (1.04 ml/20 grams of body weight). Blood samples were examined by using a spectrophotometer. Dose II and Dose III give the effect in decreasing the blood level of cholesterol in male mice, and Dose III give the effect in decreasing the blood level of LDL of male mice. Pindang patin can decrease the blood total cholesterol and LDL levels of male mice, and the best dose is in 1.04 ml/20 grams of body weight.
Folic acid played an important role in the metabolism of the body. To measure the serum folic acid levels could use the folate binding protein (FBP) from cow's milk with a technique analogous to ELISA. The aims of this study were to identify characteristics of FBP from cow's milk and binding capacity of FBP to folic acid and to purify FBP from other whey protein passed through DEAE-cellulose chromatography column. Each of DEAEcellulose peaks was passed in affinity chromatography column. FBP was released from affinity column with sodium acetate buffer pH 3.5. The purity of obtained FBP was demonstrated by a single spot in SDS-PAGE analysis and the estimated molecular weight of FBP was around 31 kDa. Our study indicated that 1 mol FBP bound 1 mol folic acid. Alkylation with iodoacetic acid decreased the binding capacity of FBP which suggested the presence of a-SH or imidazol group in its active site. The importance of disulfide bridge was proven by decreasing of folate binding capacity of FBP after β β β β β-mercaptoethanol treatment. In contrary, the folate binding didn need Ca 2+ ion, as indicated by EDTA test which gave the same result as control.
Background<br />Smoking is the act of introducing toxic substances into the body. Cigarette smoke contains chemicals that may cause several disorders, including cardiovascular disease, cancer, and chronic obstructive pulmonary disease. Toxic substances in cigarette smoke have the potential to increase free radicals, malondialdehyde (MDA) levels and to decrease endogenous antioxidant (glutathione/GSH) levels. This study aims to determine the relationship of smoking with plasma GSH and MDA levels in medical students.<br /><br />Methods<br />This study was analytical observational with cross-sectional approach. The study was conducted from April to December 2015. The subjects in this study were medical students, consisting of 20 smokers and 20 nonsmokers. Plasma GSH and MDA levels were determined biochemically using Sigma GSH Assay Kit and Sigma MDA Assay Kit. Data was analyzed using the independent t test. <br /><br />Results<br />The results showed that there was no significant difference between mean GSH in smokers (1.74 ± 0.91 mmol/L) and nonsmokers (2.42 ± 1.19 µmol/L) (p=0.441). Mean smokers MDA level of 2.06 ± 1.39 nmol/mL was not significantly different compared with mean nonsmokers MDA level (1.32 ± 0.90 nmol/mL) (p=0.092).<br /><br />Conclusions<br />Smoking tends to decrease plasma GSH levels and increase plasma MDA levels in medical students. Smoking history could be evidence of oxidative stress and an impaired oxidant defense system. In particular, young smokers should quit promptly before health problems arise, so as to have the optimal benefits of cessation.
