Effect of Cholecystokinin-8 (CCK-8) on Blood Pressure and Blood Content of Calcitonin-Gene-Related Peptide (CGRP) in Rats with Hypertension Caused by Fructose or Inhibition of Nitric Oxide Synthesis.

We studied the effect of CCK-8 on BP and blood content of CGRP in rats with hypertension caused by fructose or inhibition of NO synthase with L-NAME. The decrease in the CGRP content was found during the development of fructose-induced hypertension, but not L-NAME-caused hypertension. Administration of CCK-8 to fructose-fed animals reduced BP and increased the content of CGRP.

Effect of Transcutaneous Electrical Stimulation of Nerves on Blood Pressure and Blood Content of Neuropeptide CGRP and Nitric Oxide in Hypertensive Rats with Metabolic Disturbances.

The development of arterial hypertension in male Wistar rats with fructose-induced metabolic syndrome (12.5% of fructose solution as the only drinking source for 10 weeks) along with impaired glucose tolerance and increased serum concentration of triglycerides and LPO products caused a decrease in the content of serum blood calcitonin gene-related peptide (CGRP). Low-frequency transcutaneous electrical nerve stimulation (1 mA, 2 Hz, 10 min daily for 2 weeks) performed in 8 weeks after the beginning of fructose treatment reduced systolic BP and serum concentration of triglycerides and LPO produces and improved glucose tolerance.

[ROLE OF CAPSAICIN-SENSITIVE NERVES IN THE REGULATION OF DEHYDROEPIANDROSTERONE SULFATE BLOOD CONTENT UNDER NORMAL AND FRUCTOSE-INDUCED METABOLIC SYNDROME].

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.

[The effect of destruction of rat capsaicin-sensitive nerves on blood pressure in rats with metabolic syndrome].

The effect of destruction of capsaicin-sensitive nerve (capsaicin 150 mg/kg, s/c) on blood pre- ssure was investigated in rats with metabolic syndrome induced by fructose (12.5% in drinking water for 10 weeks). The blood plasma concentrations of glucose, triglyceride (TG) and products of lipid perioxidation were defined in these rats.

[Effects of capsaicin on oxidative modification of blood plasma proteins and arterial blood pressure in fructose-fed rats].

The influence of the activation of capsaicin-sensitive nerves with capsaicin on the oxidative modification of blood plasma proteins and arterial blood pressure was studied in Wistar rats fed with 12.5% fructose in drinking water for 10 weeks. The obtained results indicate that fructose feeding induces an increase in the arterial blood pressure and the content of plasma blood protein carbonyl derivates.
