摘要 <正>老年高血脂患者中性粒细胞吞噬功能的测定,对于研究高血脂患者的免疫功能具有重要意义。本文研究采用酵母吞噬法,观察正常人及高血脂患者中性粒细胞的吞噬功能,以及正常老年人红细胞对其影响。以探讨高血脂患者的免疫状况。 1 对象和方法 1.1 对象 按健康老年和血脂水平分为高血脂组和正常对照组。高血脂组41例,年龄60~80岁,平均65.4岁,全部为男性,血清总胆固醇>5.72mmol/L、血清甘油三酯(TG)>1.43mmol/L。正常对照组15例,年龄60~80岁,平均64.7岁,均为男性,血脂水平正常。 1.2 方法 ①酵母菌悬液配制:致敏酵母菌(购自上海长海医院)加生理盐水,离心洗涤,调成1×10~8/ml。②中性粒细胞悬液配制:待测血肝素抗凝,经淋巴细胞分离液分离,取红细胞上面的粒细胞层分离出粒细胞,按白细胞计数,配制成5×10~6/ml浓度。③红细胞悬液:用生理盐水洗涤,配制成2×10~8/ml浓度。④红细胞增强吞噬试验,参考郭峰法。
