血清胆碱酯酶与血脂的关系

通过对749例40～60岁工人SChE和血脂水平的分析,结果显示SChE与TC、TG、LDL-C和VLDL-C呈正相关,与HDL-C呈负相关,相关系数分别为0.21,0.23,0.12,0.11和-0.08。高脂血症患者的SChE活性(2271.8±650.7u/L)高于血脂正常者(1968.6±607.0u/L),但冠心病患者的SChE活性(2242.8±499.4u/L)与高脂血症组无差异。在各型高脂血症中,只有高甘油三酯血症(2241.5±623.9u/L)和混合性高脂血症患者(2561.5±704.8u/L)的SChE活性增高,而高胆固醇血症患者的SChE活性(2034.8±640.0u/L)与血脂正常者无差异(p>0.1)。提示SChE与血脂之间存在一定的联系,本文对此关系进行了讨论。     

Interpretation of Serum Calcium in Patients with Abnormal Serum Proteins

Two hundred consecutive specimens received in this laboratory for “liver function tests” showed a wide range of abnormal protein concentrations. Calcium concentration correlated closely with albumin (r = 0·867) but less closely with total protein (r = 0·682). A simple formula for adjusting calcium concentration was derived from the regression equation of calcium on albumin. Adjusted calcium = calcium - albumin + 4·0, where calcium is in mg/100 ml and albumin in g/100 ml.Low calcium concentrations were found in 49 (24·5%) and raised concentrations in six (3%) of the 200 blood specimens taken for liver function tests. After adjustment, the 95% limits of the observed range were identical with the 95% limits of the normal range determined in this laboratory. Unlike adjustments based on total protein or specific gravity, the adjustment on albumin in 39 specimens which showed hypergammaglobulinaemia on electrophoresis gave normal calcium concentrations.
