A comparative study of the generation of hydroxyl radicals (OH*) in the hypertrophic myocardium of SHR-SP rats (n = 8) and in the myocardium of WKY (n = 5) and Wistar (n = 12) rats was performed using the microdialysis technique. The experiments were carried out on anesthetized open-chest male rats (ketamine intraperitoneally, 10 mg/kg) with artificial ventilation. The amount of OH* produced was estimated by high-performance liquid chromatography with electrochemical detection using as a marker 2,3-dihydroxybenzoic acid (2,3-DHBA), a product of the reaction of the hydroxyl radical with salicylic acid added to the perfusate. The quantity of 2,3-DHBA in the dialysate was estimated by the external standard method and expressed in percent of the 2,3-DHBA concentration in the perfusion fluid. The mean baseline value of 2,3-DHBA in dialysate samples in SHR-SP rats (157 +/- 22%, n = 8) was significantly higher than in Wistar (90 +/- 15%, n = 12, p = 0.0001) and Wistar-Kyoto rats (106 +/- 12%, n = 5, p = 0.005). The basal 2,3-DHBA level in SHR-SP rats was positively correlated (r = 0.831, n = 7, p < 0.05) with the degree of hypertrophy of the left ventricle expressed as the ratio of the left ventricle weight to the body weight. The data presented demonstrate that the hypertrophy of the left ventricle in SHR-SP rats is accompanied by the elevation of the level of free oxygen radicals.
