title: [ROLE OF CAPSAICIN-SENSITIVE NERVES IN THE REGULATION OF DEHYDROEPIANDROSTERONE SULFATE BLOOD CONTENT UNDER NORMAL AND FRUCTOSE-INDUCED METABOLIC SYNDROME].
abstract: The effects of the stimulation of capsaicin-sensitive nerves (capsaicin, 1 mg/kg, s/c) and their eafferentation (capsaicin, 150 mg/kg, s/c) on the blood content of dehydroepiandrosterone sulfate (DHEAS) was investigated in normal rats and rats with fructose-induced metabolic syndrome (12.5% fructose solution, 10 weeks). An increase in blood of tryglyceride, lipid peroxidation, glucose (fasting and after loading glucose, 2 mg/kg, i/p) was considered as symptoms of metabolic syndrome. It was shown that in normal rats drinking tap water the stimulation of capsaicin-sensitive nerves resulted in the increase of DHEAS content while their deafferentation reduced the concentration of this hormone in the blood. The fructose diet caused the decrease in content of DHEAS, triglyceridemia, lipid peroxidation, impaired tolerance glucose. In rats with the metabolic syndrome the stimulation capsaicin-sensitive nerves prevented the fructose-induced decrease of DHEAS content as well as decreased the symptoms of metabolic syndrome. In fructose fed rats the stimulation-induced effects were prevented by the deafferentation of capsaicin-sensitive nerves. It is suggested that capsaicin-sensitive nerves contribute both to the regulation of blood content of DHEAS under normal and fructose-induced metabolic syndrome.
