Introduction: It was found that vitamin D may have a direct effect on adipocyte differentiation and metabolism and might be involved in the glucose regulation of insulin secretion, as suggested from the discovery of a nuclear localization of 1,25-(OH)(2)D(3) in pancreatic islets. In recent years, several polymorphisms in the VDR gene which are able to alter the activity of VDR protein have been described. The BsmI and FokI polymorphisms were described in relation to obesity and type 2 diabetes.

Material And Methods: The study group consisted of 176 healthy men, aged 25-65 years (average 54.16 years).
Introduction: Some studies indicate, that the Trp(64)/Arg(64) polymorphism of beta(3)-adrenergic receptor (ADRB3) is associated with obesity, insulin resistance and earlier onset of type 2 diabetes mellitus. The aim of our study was evaluation of frequency of this ADRB3 polymorphism and his association with metabolic syndrome parameters and oxidative stress in postmenopausal women.
Material And Methods: We performed the study among 94 women, aged 50-60, selected randomly from Wroclaw city population.
Aim: Some studies indicate that the Trp64Arg polymorphism in the gene encoding the beta3-adrenergic receptor (ADRB3) is associated with obesity, insulin resistance and earlier onset of type 2 diabetes mellitus. The aim of the present study was to evaluate the frequency of this polymorphism and its relationship with obesity and oxidative stress in postmenopausal women.
Material And Methods: We performed the study on 200 women, aged 50-60 years.
Objective: Data concerning the relationship between sex steroid hormones and the cellular antioxidative enzyme system are controversial. We investigated the effects of oestradiol deficiency after menopause and the influence of transdermal oestradiol therapy (ET) and hormonal (oestradiol plus medroxyprogesterone) replacement therapy (HT) on erythrocyte superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and catalase (CAT). GSH and selenium (Se) concentrations were also estimated.

Peroxisome proliferator activated receptors (PPARgamma) are one of the factors influencing insulin sensitivity. As a transcriptional factor it plays a crucial role in the regulation of genes involved in insulin action.

It is transcriptional factor that plays a crucial role in the regulation of genes involved in lipid utilisation and storage as well as insulin action. The objective of this study was to evaluate whether PPARgamma Pro12Ala and Pro115Gln polymorphisms are connected with obesity and its anthropological parameters.
