Abstract

Cigarette smokes produce a large number of oxidants and promote secretion of ferritin byalveolar macrophages which are potential to encourage the lipid peroxidation. Malondialdehyde(MDA) is used as a parameter of lipid peroxidation. The study was aimed to evaluate therelationship between blood level of vitamin A and ferritin and MDA among Javanese malesmokers. Sixty men who lived in Purworejo District, Central Java, Indonesia comprising 30smokers as case group and 30 nonsmokers as control group were involved in this study. Bloodsample was obtained from cubiti vein and then centrifuged to obtain plasma or serum. Blood levelsof vitamin A, ferritin and MDA were measured by HPLC, ELISA and spectrophotometric methods,respectively. The result showed that the blood vitamin A, ferritin, and MDA levels in smokers were25.09±9.51μg/dL, 35.50±24.17ng/dL, 1.15±0.42μg/L, respectively, whereas in non smokers, theywere 26.11±9.19 μg/dL, 38.60±15.25 ng/dL, 1.06±0.50 μg/L, respectively. Therewas no significantdifference of the blood vitamin A, ferritin, and MDA levels between smokers and the non smokers(p>0.05). The linear regression analysis indicated that there was negative relationship betweenblood vitamin A and MDA levels although it was not significant (p=0.052), while blood ferritin andMDA levels had a significantly positive relationship (p=0.010). In conclusion, the low level of bloodvitamin A among cigarette smokers does not lead to high blood MDA level, while high level of bloodferritin among smokers leads to high blood MDA level.

Abstract

Low expression of insulin receptor substrate 1 (Irs1) is associated with insulin resistance and type 2 diabetes mellitus (type 2 DM). This study was performed to evaluate the effects of Dioscorea esculenta and Eubacterium rectale on the Irs1 expression in the skeletal muscle and the homeostatic model assessment-insulin resistance (HOMA-IR) of diabetic rats. Twenty-five male Wistar rats were divided into five groups i.e. non diabetic rats Group 1; diabetic rats as Group 2; diabetic rats + D. esculenta as Group 3; diabetic rats + E.rectale as Group 4 and diabetic rats + both E. rectale and D. esculenta as Group 5. Rats were made diabetic with induction of intraperitoneally injection of nicotinamide and streptozotocin. After four weeks of the interventions, the blood and skeletal muscles were taken. The Irs1 expression was analyzed with immunohistochemical staining, plasma glucose levels was analyzed using a spectrophotometer, and insulin was analyzed using ELISA methods. All intervention groups reduced plasma glucose levels and HOMA-IRs (p<0.001) and increased Irs1 expression. The greatest reduction of  plasma glucose levels and increase of Irs1 expression in the skeletal muscle were found in Group 4, however, the lowest of HOMA-IR was seen in Group 5. These results suggested that D.esculenta, E.rectale, and the combination reduced plasma glucose levels and HOMA-IR by increasing Irs1 expression in skeletal muscle.

Abstract

Accumulation of cholesterol in the blood will cause stiffness in arteries and trigger the formation of atherosclerotic lesions. Estrogen has a role as an antioxidant that can prevent the low density lipoprotein(LDL) oxidation. In menopause with high-fat diet, the decrease of estrogen levels will trigger cholesterol accumulation in the blood lead to endothelial dysfunction mediated by endotelin-1 (ET-1) and nitric oxide synthase (eNOS). This study aimed to investigate the effect of long-term high-fat diet on the lipid profile, serum eNOS and ET-1levels on ovariectomized rat. It was experimental using 28 female Wistar rat divided into 4 groups. Group 1 was ovariectomized mice and given a standard diet (OVX-SD), Group 2 was ovariectomized mice and given a high-fat diet (OVX-HFD), Group 3 was not ovariectomized mice and given a standard diet(SHAM-SD) group, and Group 4 was not ovariectomized mice and given a high-fat diet (SHAM-HFD).Lipid profile of blood samples was measured pre- and post-treatment, whereas serum eNOS and ET-1 levels were measured post-treatment using ELISA method. No significantly difference of lipid profileon OVX-HFD group compared to that OVX-SD was observed. The serum eNOSlevel on OVX-HFD(702.11±68.73 pg/mL) was significantly lower than that OVX-SD (857.18±118.08 pg/mL) (p<0.05). However, there was no significantly different of serum ET-1 levelbetween OVX-HFD group (299.14±146.61 pg/mL) compared to that OVX-SD (194.25±102.96 pg/mL) (p>0.05). In conclusion, the serum eNOS levelon ovariectomized rat with long-term high-fat diet is lower than that on ovariectomized rat with standard diet.
