摘要目的 研究DSG型生物信息红外肝病治疗仪(BILT肝病治疗仪)对小鼠肝脏微循环的影响.方法 将40只SPF小鼠造模后随机均分为未照射模型组、冷光源照射模型组、红外线照射模犁组和BILT肝病治疗仪照射模型组,另取20只正常小鼠作为对照.每组分别以激光多普勒血流仪测定肝脏血流量并以显微活体视频技术观察肝脏微循环血流速度,同时进行肝脏病理学检查和血清生化学检查.结果 BILT肝病治疗仪照射模型组肝脏平均血流灌注量与未照射模型组比较明显增加(P=0.004),而冷光源、红外线照射模型组与未照射模型组比均无明显增加血流量作用(P=0.713和0.465).未照射正常组较未照射模型组小鼠肝脏微血管内红细胞平均流速快,差异有统计学意义(P=0.001);BILT肝病治疗仪照射模型组肝脏微循环平均流速较未照射模型组、冷光源照射模型组和红外线照射模型组的流速也有所增加,差异有统计学意义(P=0.004、0.020和0.030).BILT肝病治疗仪照射模型组AST活性较未照射模型组明显降低(P=0.027),该组羟脯氨酸(Hyp)平均含量低于未照射模型组,但差异无统计学意义(P=0.433).结论 BILT肝病治疗仪可改善肝纤维化小鼠肝脏的微循环并降低肝纤维化小鼠血清AST活性,改善肝脏病理状态.

abstractsObjective To investigate the effect of DSG biologic information infrared liver disease therapy instrument(BILT liver disease therapy instrument)on liver microcirculations in mice.Methods Liver fibrosis was induced in 40 SPF mice which were randomized into 4 groups:without irradiation group,coht light irradiation group,infrared light irradiation group and BILT group(10 in each group).Twenty healthy mice were taken as the control.Liver blood flow of each group was observed by laser-Doppler flow instrument,and blood flow rate of liver microcirculation in each group was observed by intravital microscopy.Pathological examination and serum biochemistry were also performed.Results In fibrosis mice,the liver blood flow in average of BIUF group Was higher than that of without irradiation group(P=0.004),while comparing with without irradiation group there were no significant differences in liver blood flows of the cold light irradiation group and infrared light irradiation group(P=0.713 and 0.465).Red blood cell velocity of microvessels in average of the healthy group(without irradiation)wag higher than that in the without irradiation group offibrosis mice(P=0.001),and it in the BILT group(fibrosis mice)Was also higher than those in other groups of fibrosis mice(P=0.004,0.020 and 0.030).For fibrosis mice,the average AST in BILT group was lower than that in the without irradiation group(P=0.027),and the difference in hydroxyproline(Hyp)levels between the groups was not of statistical significance(P=0.433).Conclusion BILT liver disease therapy instrument can improve the liver microcir-culation,reduce AST level and improve liver pathological state in mouse with fibrosis.
