A new method, enzyme immunoassay (EIA), for diagnosis of malayan filariasis is described.Of 101 sera from microfilaria carriers tested by the EIA, 97(96. 1%) were positive with 1:40 dilution and 92(91.1%) with 1:80, while of tha 200 healthy persons tested the false-positivity rates were 4% with 1:40 and 1.5% with 1:80. The criterion for positive diagnosis was drawn as follows. Double positives with 1:40 and 1:80 was regarded as positive reactors, and thosepositive with 1:40 alone as doubtful positive reactors....

A new method, enzyme immunoassay (EIA), for diagnosis of malayan filariasis is described.Of 101 sera from microfilaria carriers tested by the EIA, 97(96. 1%) were positive with 1:40 dilution and 92(91.1%) with 1:80, while of tha 200 healthy persons tested the false-positivity rates were 4% with 1:40 and 1.5% with 1:80. The criterion for positive diagnosis was drawn as follows. Double positives with 1:40 and 1:80 was regarded as positive reactors, and thosepositive with 1:40 alone as doubtful positive reactors. By using this criterion a sensitivity of 91.1% and a specificity of 97.5% were obtained.No cross reactions occurred between microfilaria antigen and the sera from the patients with schistosomiasis (20 cases) and paragonimiasis (15 cases). But 1 out of the 10 sera from patients with hookworm disease gave positive cross reaction.Satisfactory reproducibility of the EIA was demonstrated by a comparative experiment, in which 14 known positive and 15 negative sera were tested repeatedly at 10-day's interval.In the field trial, of the 480 subjects living in filariasis endemic areas, both thick film examination and EIA were employed 7 microfilaria carriers were detected by the thick films asthey were also. EIA positive reactors and 20 positive reactors and 24 doubtful positive reactors by the EIA.It is thought that this EIA could be used as a tool for diagnosis of malayan filariasis.

以微丝蚴固相抗原酶免疫试验法,检查了101例微丝蚴血症患者和200例健康人。按本文拟订的标准判断阳性、可疑阳性、假阴性和假阳性率分别为:91.09%,7.92%,0.99%和1.5%。在与血吸虫、肺吸虫和钩虫病人血清作交叉试验中,仅发现与钩虫病人(1/10)有交叉阳性。用本法和厚血膜片法现场检查了480例,发现前者阳性20例,后者7例(其酶免疫试验均阳性)。初步认为,本法诊断丝虫病具有较好的敏感性、特异性和重现性,因而具有一定实用价值。

Cytological specimens, i. e. prints or smears were prepared from fib-rogastroscopy biopsied materials from 145 patients, with various gastric diseases, including 50 cases of gastric carcinoma. The preparations were stained with acri dine orange and examined by fluorescence microscopy. The results were compared with those of histopathological observations. Out of 50 cases of gastric carcinoma, 48 cases were detected by this procedure, showing a specificity rate of 96.0% and a sensitivity rate of 96.8%....

Cytological specimens, i. e. prints or smears were prepared from fib-rogastroscopy biopsied materials from 145 patients, with various gastric diseases, including 50 cases of gastric carcinoma. The preparations were stained with acri dine orange and examined by fluorescence microscopy. The results were compared with those of histopathological observations. Out of 50 cases of gastric carcinoma, 48 cases were detected by this procedure, showing a specificity rate of 96.0% and a sensitivity rate of 96.8%. We concluded that fluorescence microscopy on acridine orange stained cytological preparations is a simple and easy procedure. It is less time consuming and should be considered to be one of the efficient diagnostic measures supplementary to fibrogastroscopy.

Transesophageal atrial pacing was performed and the sinus node recovery time(SNRT),the corrected SNRT(CSNRT)and the intrinsic heart rate (IHR_0)were obtained in 30 healthy elderly subjects and 12 elderly patients (over 60 years)with Sick Sinus Syndrome(SSS)before and after autonomic blockade by administering atropine and propraonlol,i,v.Twenty-eight healthy subjects and 30 patients under 60 years were also studied for comparison.The results showed that SNRT and CSNRT obtained after blockade had much higher sensitivities and accuracies for SSS than those obtained before(100% vs 66.67% for sensitivities,97.62% for accuracies),and had the same specificities(96.67%) both before and after blockade.IHRo/IHRp-2SD<1 had a specificity of 100% and an accuracy of 85.71% for SSS,although the low sensitivity(50%).

本文对30名健康老年人和12例老年病窦患者(年龄60~75岁)在自主神经阻滞(静注阿托品和心得安)前后作经食道心房调搏和固有心率(IHRo)测定,并与中年组作对照。结果发现:自主神经阻滞后测得的窦房结恢复时间和校正窦房结恢复时间对诊断老年人病窦的敏感性和准确性比阻滞前大大提高(敏感性由66.67%提高到100%,准确性由88.1%提高到97.63%),而特异性不变(均为96.7%)。用 IHRo/IHRp-2SD<1诊断老年人病赛的特异性达100%,准确度也高(85.71%),但敏感性较低(50%)。在老年人中应用自主神经阻滞方法安全可行。
