BACKGROUND: There are pressure sensors in carotid-sinus, which are very sensitive to blood pressure regulated by ions and play an important role in the regulation of blood pressure. But it is yet not very clear how different ions regulate the blood pressure through pressure sensors in carotidsinus.OBJECTIVE: To observe the effect of different ions at various concentrations outside the carotid-sinus.DESIGN: Self-control experiment.SETTING: Preclinical Experiment Center, Fourth Military Medical University of Chinese PLA.MATERIALS: The experiment was accomplished in the Preclinical Experiment Center, Fourth Military Medical University of Chinese PLA from December 2000 to June 2001. Totally 18 New Zealand pure strain rabbits were provided by the Aninal Experimenting Center of Fourth Military Medical University of Chinese PLA. They were standard grade Ⅱ, of either gender and body mass was (2.0±0.2) kg.METHODS: The rabbits were divided into Na+, K+ and Ca2+ groups according to random numbers, and each group consisted of 6 rabbits. After anaesthesia, tracheal intubatton was performed on the rabbit, and bilateral carotid arteries were separated with carotid-sinus separated on one side and vessel intubatton performed in the other side for blood pressure measurement. Then various concentrations of Na+, K+ and Ca2+ ions were added outside the carotid-sinus with the pipette to make the carotid-sinus completed immersed in the ion solutions. The basal blood pressure and the peak value after ions addition were recorded respectively.MAIN OUTCOME MEASURES: The basal blood pressure and the peak value after ions addition.RESULTS: After Na+ (0.15, 1.5 mol/L) was added the blood pressure was(97±12), (83±17) mm Hg. It was decreased significantly compared with the basal value (106±14), (105±12) mm Hg (t=2.946, P ＜ 0.05). K+ (0.4 mol/L)decreased the blood pressure significantly [(106±12), (64±13) mm Hg, (t=13.496, P ＜ 0.01)], but other concentrations of K+ were not effective. Ca2+(0.07 mol/L) increased the blood pressure to (113±16) mm Hg compared with the basal value (103±12) mm Hg (t=-3.627, P ＜ 0.01).CONCLUSION: Na+, K+ and Ca2+ regulate the blood pressure by acting on the carotid-sinus directly. High concentrations of Na+ and K+ possess the effect of decreasing the blood pressure, while high concentrations of Ca2+increases it, which may be an important mechanism of blood pressure regulation.

AIM To investigate the effects and mechanism of cardiomyocyte hypertrophy induced by urocortin. METHODS The cardiomyocytes were divided into 8 groups: normal control, urocortin, staurosporine(Sta), verapamil(Ver), H89, urocortin+Sta, urocortin+Ver, and urocortin+H89 groups. The cardiomyocytes diameter was measured by computer photograph analysis system. The protein synthetic rate was obtained through measuring the incorporation of [~3H]-leucine into myocyte protein by liquid scintillation method. The total protein content was assayed by Lowry method. The expression of atrial natriuretic peptide (ANP) was determined by Western blot. [Ca~(2+)]_i transient was measured by Till image system by cell loading Fura-2/AM. RESULTSUrocortin group enhanced cardiomyocyte volume, protein synthesis, total protein content and expression of ANP by 30.9%, 36.3%, 35.5% and 34.7%;urocortin+Sta group decreased cardiomyocyte diameter, protein synthesis, total protein content and expression of ANP by 16.5%, 22.1%, 18.1% and 21.3%;urocortin+H89 group decreased the cardiomyocyte diameter, the protein synthesis,total protein content and expression of ANP by 16.6%, 21.5%, 19.5% and 20.6%;urocortin+Ver decreased the cardiomyocyte diameter, the protein synthesis, total protein content and the expression of ANP by 17.1%, 20.9%, 17.9% and 19.9%;Sta, H89 and Ver could decrease the [Ca~(2+)]_i transient induced by urocortin. CONCLUSION The hypertrophic effect of urocortin in rat neonatal cardiomyocytes is mediated via activation of protein kinase C and protein kinase A pathway and L-type calcium channels.
