Chronic alcoholics are very often found to be deficient in vitamins. The object of the study was to assess the vitamin utilization of twelve drinking chronic alcoholics after intravenous therapy with polyvitamins. The following enzyme activation tests in red blood cells were used: a) Erythrocyte transketolase (ETK) activity for B1; b) Glutathione reductase (EGR) activity for B2; c) Pyridoxal-5-phosphate (PALP)--the active metabolite of vitamin B6 (pyridoxine) was directly estimated in red blood cells. Seven out of 12 patients were deficient in B1 before treatment; 6/12 in B2 and 11/12 in PALP. But all returned to normal after treatment; mean plus or minus SD of ETK activation co-efficient improved from the pre-treatment level of 1.174 plus or minus 0.135 to 1.001 plus or minus 0.009 (adequate less than or equal to 1.15); mean plus or minus SD of EGR activation coefficient from 1.265 plus or minus 0.333 to 1.015 plus or minus 0.072 (adequate less than or equal to 1.19) and PALP rose from 6.78 plus or minus 6.47 to 60.68 plus or minus 85.85 after treatment (adequate = vv10-20 ng/ml). These observations indicate the need for relevant vitamin supplementation in chronic alcoholics and also support the inclusion of intravenous polyvitamins in conventional detoxification regime for chronic alcoholics.
经常发现慢性酗酒者缺乏维生素。本研究的目的是评估12名饮酒的慢性酗酒者在接受静脉注射多种维生素治疗后的维生素利用情况。采用了以下红细胞中的酶激活试验:a)用于检测维生素B1的红细胞转酮醇酶(ETK)活性;b)用于检测维生素B2的谷胱甘肽还原酶(EGR)活性;c)直接测定红细胞中维生素B6(吡哆醇)的活性代谢产物磷酸吡哆醛(PALP)。12名患者中有7名在治疗前缺乏维生素B1;6名缺乏维生素B2,11名缺乏PALP。但治疗后所有指标均恢复正常;ETK激活系数的均值±标准差从治疗前的1.174±0.135提高到1.001±0.009(正常范围≤1.15);EGR激活系数的均值±标准差从1.265±0.333提高到1.015±0.072(正常范围≤1.19),治疗后PALP从6.78±6.47上升到60.68±85.85(正常范围=10-20 ng/ml)。这些观察结果表明慢性酗酒者需要补充相关维生素,也支持在慢性酗酒者的传统解毒方案中加入静脉注射多种维生素。
