Click-evoked cortical potentials were recorded in guinea pigs before and after exposure to intensive impulse noise and their computer-averaged amplitudes at different click levels were compared. Post-exposure responses to high-intensity click (peak level 90-120 dB) were systematically augmented, a result quite contradictory to the general rule of the effect of exposure to noise. The maximum post-exposure amplitude might exceed the maximum pre-exposure value by 30-120%. The dosage...

Click-evoked cortical potentials were recorded in guinea pigs before and after exposure to intensive impulse noise and their computer-averaged amplitudes at different click levels were compared. Post-exposure responses to high-intensity click (peak level 90-120 dB) were systematically augmented, a result quite contradictory to the general rule of the effect of exposure to noise. The maximum post-exposure amplitude might exceed the maximum pre-exposure value by 30-120%. The dosage of exposure seemingly appropriate for this kind of amplitude augmentation was found to be 100-500 wide-spectrum impulses of 150 dB peak SPL and 50 ms duration, or 2000 impulses of 146 dB and 10 ms. A 15 minutes exposure to 105 dB steady white noise also gave marked amplitude augmentation. Temporal response threshold shift 5-20 min after exposure amounted to 16-48 dB. Latency of the maximum response after exposure increased on the average by about 15%. Overdosage of exposure (e.g. 1000 impulses of 150 dB and 50 ms duration) caused a decrease in stead of an increase of the response amplitude and was accompanied by a large threshold shift (up to 68 dB).

在适当剂量强噪声暴露后,豚鼠听皮层由较强短声诱发的电位振幅可以增大。脉冲噪声峰值150dB脉宽50ms100—500次,或146dB脉宽10ms2000次,或持续白噪声105dB15min,可使暴露后的最大电位比暴露前的增大30—120%,其潜伏期平均约延长15%,5—20min内的暂时性阈移为16—48dB。过大的暴露剂量则使电位变小。在皮层诱发电位增大的同时,耳蜗电位、内膝体及小脑诱发电位均不增大。皮层电位的增大现象不受麻醉、掩蔽及皮层表面放置马钱子素的影响。

Data on blood and urine lead concentrations, free erythrocyte protoporphyrin, zinc protoporphyrin of 154 workers occupationally exposed to lead (air concentration, 0.05-5.0 mg/m3TWA) were compared with those of 163 nonexposed controls, after discriminative analysis and screening effectiveness validity processing. A good exposure-effect and exposure-response relationships are demonstrated, the sensitivity, specificity, coherence and predictive values of these para-meters were individually calculated...

Data on blood and urine lead concentrations, free erythrocyte protoporphyrin, zinc protoporphyrin of 154 workers occupationally exposed to lead (air concentration, 0.05-5.0 mg/m3TWA) were compared with those of 163 nonexposed controls, after discriminative analysis and screening effectiveness validity processing. A good exposure-effect and exposure-response relationships are demonstrated, the sensitivity, specificity, coherence and predictive values of these para-meters were individually calculated and compared. After discriminant analysis PbB 35μg/dl, FEP 45μg/dl, ZPP 70μg/dl, as well as PbU 35μg/L were all found to be suitable for preliminary screening. The combination of FEP and PbU is recommended to be adapted in screening for their effectiveness and availability.

本文对154名铅接触工人,空气铅浓度0.05~5.0mg/m~3(TWA)和163名非铅接触者的血铅(PbB)、红细胞游离原卟啉(FEP)、红细胞锌原卟啉(ZPP)、和尿铅(PbU)的测定结果进行了统计分析。接触-效应和接触-反应之间均有很好相关。用判别分析求得PbB35μg/dl,FEP 45μg/dl,ZPP 70μg/dl,PbU 35μg/L作为检测基准是适宜的。对这些指标的检测效能作了检验,并表明两个检测指标合用比单用一个指标的分辨效果为好。建议取FEP,PbU两项指标合用作铅接触者的检测较为理想。用FEP(X_1),PbU(X_2)两项指标计算得到的判别式Z=0.01901 X_1+0.0001096 X_2,和临界值Z_0=0.035作为对空气铅浓度的监测判别初筛;以Z=0.01477 X_1+0.0000558 X_2,Z_0=0.0278监测判别接触者的血铅。

One thousand one hundred and seventy-four workers expososed to textile industrial noise of 72~104 dB (A) noise level were examined in this epidemiological survey. It was found that 11.33% of these workers were hypertension(including borderline hypertenslon)and 6.56% were of abnormal heart rate, including tachycardiac and bradycardiac, all significantly different from those of the control group. There were positive relations between hypertension morbidity and noise level, and length of exposure, indicating...

One thousand one hundred and seventy-four workers expososed to textile industrial noise of 72~104 dB (A) noise level were examined in this epidemiological survey. It was found that 11.33% of these workers were hypertension(including borderline hypertenslon)and 6.56% were of abnormal heart rate, including tachycardiac and bradycardiac, all significantly different from those of the control group. There were positive relations between hypertension morbidity and noise level, and length of exposure, indicating exposure-response relationship. Also there was a direct association between hypertension and age. The characteristics are: (1) Linear regresson coefficient of the noise group was higher than that of the control group, indicating that those Subjects exposed to noise had a significantly greater risk of developing hypertension. (2) Hypertension appeared at relatively young ages(30~39 years) and increased with age. This study emphasize the need for, at least annually, periodic examination of the persons with exposure to textile industrial noise in order to detect early adverse effects in cardiovascular system and to consider medical care.

调查接触纺织噪声强度为72~104dB(A)的1174名纺织工人的血压和心率,结果发现其高血压病(含临界高血压)患病率为11.33%,心率异常患病率为6.56%,均显著高于对照组,且与噪声强度及工龄呈正相关。其特征是:(1)噪声组直线回归高于对照组,两组回归系数有显著性差异。(2)噪声组的高血压病病例开始出现在较年轻组。30~39岁组高血压病患病率已显著高于对照组,并随年龄增长而增高。表明噪声接触者发生高血压病的危险性较大。
