Purpose: Retinol binding protein 4 (RBP4) has recently been identified as an adipokine possibly involved in the development of impaired glucose metabolism. We aimed to test serum RBP4 in healthy non-obese individuals and in patients with well-characterized phenotype: obesity without confounding effects of diabetes, metabolic syndrome or dyslipidaemia. Additionally, we examined whether serum RBP4 is associated with anthropometric parameters, insulin resistance and blood lipid parameters.

Materials And Methods: Fourteen recreational female swimmers aged 45 ± 8.7 years, regularly swimming outdoors during winter months were exposed to cold water at least twice a week.
We determined whether cold water swimming for six consecutive months results in adaptive changes in body composition and insulin sensitivity. Thirty healthy subjects aged 50.2 ± 9.

Since identification in 1994 of leptin, a hormone produced by adipocytes, adipose tissue has become the subject of intensive research. These studies contributed to the discovery that adipocytes have the ability to synthesize and secrete biologically active substances called "adipokines". Adipokines include a variety of cytokines, peptide hormones and enzymes that play a role in a wide variety of biological functions.

Aim: We investigated the correlation between nutritional status and plasma levels of leptin, ghrelin and insulin in lean, obese and anorexic subjects.
Material And Methods: Nineteen obese and 18 anorexic adults were enrolled in the study.
