ABSTRACT
Objective To investigate the effect of Emodin on intracellular calcium concentration ([Ca~(2+)]i) and apoptosis of hepatic cells after simulated cold ischemia-reperfusion. Methods Glucose-oxygen deprivation, low temperature, subsequent reoxygenation and rewarming were used to induce ischemia-reperfusion injury model in cultured hepatic cells which were divided into 4 groups: control group and Emodin-treated group(100, 10 and apoptosis rate were determined by flow cytometry (FCM) respectively; the content of lactate dehydrogenase (LDH) in supernatant was tested. Results Intracellular calcium fluorescence intensity in Emodin-treated groups of high, medium and low density was 24.12±0.51, 26.35±1.34 and 39.12±1.94, respectively, which were significantly lower than 105.29±1.01 in control group(P<0.01). Apoptosis rate in Emodin-treated groups of high, (179.67±18.57)u/L in Emodin-treated groups of medium and high density respectively, which were significantly lower than (351.33±34.16)u/L in control group(P<0.01). Conclusion Emodin could reduce [Ca~(2+)]i and inhibit apoptosis of hepatic cells after simulated cold ischemia-reperfusion, thus protecting hepatic cells effectively.
