[The relationship between serum level of leptin and oxidative stress in patients with hyperglycemia crisis].

Objective: To investigate the relationship between the levels of serum leptin and oxidative stress in patients with hyperglycemia crisis.

Methods: A total of 96 patients with diabetic ketoacidosis (DKA) and nonketotic hyperglycemia (NKH) were treated on a low-dose insulin protocol using intravenous infusion of insulin with the established rate of 0.1 Uxkg(-1)xh(-1), with the patients on intravenous fluids and receiving nutrition by mouth and vein.

[Circulating levels of oxidative stress and adipocytokines in obese subjects].

Aim: To investigate the relationship between adipocytokines levels and oxidative stress in obese males.

Methods: The levels of 8-iso-prostaglandinF2alpha(8-iso-PGF2alpha), superoxide dismutase (SOD), malondialdehyde (MDA), adiponectin, leptin, restistin, TNF-receptors 1(TNF-R1), Interleukin-1beta(IL-1beta) and Interleukin-6(IL-6) were measured in obese men and normal controls.

Results: The levels of 8-iso-PGF(2alpha), MDA, leptin, TNF-R1, IL-1beta and IL-6 was significantly higher than that normal controls (P<0.
