Intracellular calcium ion concentration in the prostate smooth muscle cells of chronic abacterial prostatitis rat models and normal controls / 中华男科学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the difference in intracellular calcium ion [Ca2+]i concentration in prostate smooth muscle cells (PSMCs) between SD rat models of chronic abacterial prostatitis (CAP) and normal controls, and to evaluate the role of [Ca2+]i concentration in CAP.</p><p><b>METHODS</b>We established CAP models in SD rats using purified prostate protein and Freund's complete adjuvant, cultured in vitro and then purified the PSMCs of both the CAP models and normal controls. Continuous dynamic scanning was performed under the laser confocal scanning microscope after incubation of the cells with FLUO-3AM.</p><p><b>RESULTS</b>The fluorescence intensities of [Ca2+]i in the PSMCs were 80.39 +/- 9.00 and 27.95 +/- 10.04 in the CAP models and normal controls, respectively, with statistically significant differences between the two groups (P < 0.01).</p><p><b>CONCLUSION</b>The concentration of [Ca2+]i increased in the PSMCs of the CAP rat models, which might enhance the constriction of PSMCs and subsequently increase the sensibility to pain and cause lower abdominal pain.</p>
