The glutathione contents in whole blood of 53 normal Chinese males, 52 normal Chinese females and 31 patients with gynecological cancer were determined by iodometric titration. Total glutathione levels in the whole blood of these three groups were 41.5 ± 0.74, 38.3±0.74 and 32.6±1.20 mg% respectively. A significant difference existed between the values of total glutathione in normal male and female adults; however, the contents of reduced or oxidized glutathione showed no difference. The reduced and total glutathione...

The glutathione contents in whole blood of 53 normal Chinese males, 52 normal Chinese females and 31 patients with gynecological cancer were determined by iodometric titration. Total glutathione levels in the whole blood of these three groups were 41.5 ± 0.74, 38.3±0.74 and 32.6±1.20 mg% respectively. A significant difference existed between the values of total glutathione in normal male and female adults; however, the contents of reduced or oxidized glutathione showed no difference. The reduced and total glutathione levels in the whole blood of patients with gynecological cancer were found to be lower than that of the normal; while their oxzidized glutathione levels showed a prominent increase. There was a significant positive correlatoin between the RBC counts and total glutathione levels in patients with gynecological cancer, but not the other two groups of normal subjects.Oxygen capacity in the whole blood of 46 normal Chinese males, 47 normal Chinese females and 31 patients with gynecological cancer was estimated by Scholader-rougton's miorogasometry, being 19.2 ± 0.25, 16.8 ±0.26 and 12.8 ± 0.61 ml% respectively. The difference between the values of normal male and female adults and that between those of the patients and normal females were very significant.The possible mechanism of these biochemical changes is briefly discussed.

本文著者用碘量滴定法初步观测了53名和52名我国正常男、女成人及31例妇科癌肿患者的全血谷胱甘肽含量。三组的全血谷胱甘肽总量分别为41.5±0.74,38.3±0.74和32.6±1.20毫克%。男、女成人的该测定值相差显著,但他们的全血氧化型或还原型谷胱甘肽含量则否。与正常女性组比较,妇科癌肿患者的全血谷胱甘肤总量及其还原型含量均呈明显降低,而氧化型谷胱甘肽则明显升高。正常人组的红细胞计数和全血谷胱甘肽总量无明显相关,而妇科癌肿患者则有极显著的正相关。另外,还用Scholander与Roughton 微量分析法观测了46名和47名我国正常男、女成人及31例妇科癌肿患者的全血氧容量,三组结果分别为19.2±0.25,16.8±0.26和12.8±0.61毫升%;发现正常男女之间以及妇科癌肿患者与正常女性之间均有明显差异。 对上述变化的可能机制,作了一些初步讨论。

The method (LS 76——82) of the Ministry of Commerce China, the method of Food Hygiene Iaws and Regulations of Japan and Acetic acid glacial-chloroform direct abstraction method were used to abstract fats and oils in fried instant noodle. Iodometric method was used to determine peroxide values. There methods were compared. The results indicated that the differences of the valuse were siginficant with the different methods. The values obtained by the standard method of China were lowest and the standard deviation was lowest. The values determined were highest with the method of Japan. The values were medium by acetic acid glacial-chloroform and were close to the standard method of the country. The two latter methods were similar in deviation.

An automated assay for the determination of penicillin in broth is presented.The method is based on the classical iodometric penicillin assay which is incorporated in aflow injection analysis system,The required hydrolysis is performed on line by using an im-mobilized penicillinase reactor.Enzymatic hydrolysis of penicillin results in the formation ofthe corresponding penicilloic acid, which consumes iodine,The iodine consumption is deter-mined ampermetrically by two platinum electrode and a reference electrode,Various factorswhich influence the response of the system and the performance of this system are described.Good linear relationship is obtained within the range of 0.05~0.9mol/m ̄3(40μL).The cor-relation coefficient of the calibration cure is 0.992.The frequency of determination of thissystem is more than 60 samples per hour.This enzyme reactor is stable for at least 1 0month,when it is stored in 4℃.

整个测定系统由固定化青霉素酶管、流动注射分析仪及碘分子检测池组成。测定原理基本上同碘量滴定法,即青霉素经酶管转化为青霉素噻唑酸,该酸与碘分子发生定量反应,剩余的碘用电化学方法检测。实验表明:测定线性范围为0.05~0.90mol/m ̄3(取样40μL),线性相关系数为0.992。对0.6mol/m ̄3的青霉素反复测定10次,平均值为62.49μA,变异系数为1.20%。当青霉素浓度低于1.0mol/m ̄3时,条件在一定范围的波动(磷酸盐浓度为0.05~0.25mol/m ̄3,pH为6.0~7.5,测定温度15~25℃),对测定结果几乎没有影响,测定速率可达每小时120个样品。此系统不变,在室温下(8~20℃)使用时,每天约测400个样品,酶管使用30d,未见活力下降。4℃下保存10个月,酶管活力未见明显下降。
