Abstract： 目的:观察DSG-Ⅰ型生物信息红外肝病治疗仪治疗大鼠非酒精性脂肪性肝病的疗效.方法:♂SD大鼠50只随机分组,正常对照组20只喂饲普通饲料,模型对照组及近红外光治疗组共30只喂饲高脂饲料(0.88标准普通饲料+0.10猪油+0.02胆固醇).治疗组自13 wk始进行近红外线照射治疗,于20 wk结束治疗并处死各组大鼠,测定血清ALT、AST、GGT、ALP、TP、TG、TC、LDL和HDL水平,同时观察肝组织学改变.结果:20 wk实验结束时,与正常对照组相比,模型对照组肝指数(t=8.65,P＜0.01)、血清ALT(t=4.65,P＜0.01)、AST(t=4.74,P＜0.01)、ALP(t=3.56,P<0.01)、TP(t=6.35,P＜0.01)、TC(t=8.41,P＜0.01)和LDL(t=8.86,P＜0.01)水平显著升高;肝组织脂肪变性(Z=-4.135,P＜0.01)、炎症(Z=-3.752,P＜0.01)及纤维化程度(Z=-4.156,P＜0.01)均较对照组程度重.与模型对照组相比,近红外光治疗组肝指数、血清ALT、GGT、ALP、TP、TG和TC水平均有所下降,但无统计学意义,而AST有明显降低(t=-2.404,P＜0.05);肝组织脂肪变及炎症程度较模型组轻,但无统计学意义,而肝纤维化程度较模型组减轻(Z=-3.101,P＜0.01).结论:DSG-Ⅰ型生物信息红外肝病治疗仪时大鼠高脂饮食非酒精性脂肪性肝病有一定的治疗作用.
