工作相关性上肢不适征通常表现为疼痛、无力、麻木(或刺痛)等三种神经性症状,这表明与周围神经病损有关。因此,相应的体格检查应该能够识别(或排除)是否存在神经功能损伤。本文提出了一种新的体格检查方法,此方法基于公认的经典模式,即周围神经损伤会导致其所支配的肌肉力量减弱。大部分上肢疼痛患者和存在职业性暴露的上肢疼痛患者通过上肢神经检查可以准确的诊断和定位神经痛,但这种检查方法相对复杂和费时。因此在经典方法的基础上提出了一种相对简单快速的检查方法,即对三组拮抗肌(胸部三角肌-后三角肌、肱二头肌-肱三头肌、桡侧腕屈肌-桡侧腕短伸肌)和三块单独的肌肉(尺侧腕伸肌、拇短展肌、小指展肌)进行简单快速检查的方法。临床医生可以通过这种体检,对周围神经的疼痛进行定位以确定疾病类型。大部分工作相关性上肢不适征都会表现出这些疼痛模式,但由于缺乏相应的诊断标准,传统的体检不能明确这些异常,而被列入"非特异性"疾病。建议将这9块肌肉的检查纳入到常规上肢体检中。

动物毛皮的风干

草食家畜 1987年第3期 54-56页

作者： j.C.barrett ,王征楠

在许多热带国家,特别是在盐较少的农区,家畜毛皮都是风干后保存的。除非洲外,亚洲、拉丁美洲和远东地区也出产风干皮张。如果操作合理,风干是一种非常理想的方法。过去人们认为风干的皮张质量不如盐渍皮,这是由于人们对风干皮不了解以... 详细信息

在许多热带国家,特别是在盐较少的农区,家畜毛皮都是风干后保存的。除非洲外,亚洲、拉丁美洲和远东地区也出产风干皮张。如果操作合理,风干是一种非常理想的方法。过去人们认为风干的皮张质量不如盐渍皮,这是由于人们对风干皮不了解以及晾晒时不细心造成的,而绝不是干燥方法本身的缺点。革皮的风干只能将皮吊在框架或类似的结构上。至于毛皮,既可悬吊在框架上,也可搭挂在铁丝或绳子上,但要保证皮的两面通风良好。本文仅就悬挂式风干进行论述,并

After recognising more than 25 years ago,that combustion and incineration facilities are sources for polychlorinated dioxin(PCDD)and furans(PCDF),there were developed different methods to sample and to determine the dioxin concentrations in flue gas emissions. Because all the methods were manual sampling methods,the maximum sampling times were limited to several *** spot measurements do not give reliable informations about the total PCDD/PCDF and other POPs emissions of a plant and do not help to decrease the mistrust of the residents living near to such *** continuous online monitoring of PCDD/PCDF is not feasible for compliance measurements,the continuos sampling is the method of choice for supervision of *** long-term sampling of PCDD/PCDF emissions over the whole year gives comprehensive information on the total emission of a facility and details of the emission of the chosen time periods. Therefore long term sampling with AMESA is the practical choice for continuous monitoring of PCDD/PCDF emission from waste incinerators and other industrial emission sources. The Stockholm Convention on persistent organic pollutants(POPs) lists in addition to PCDD/PCDF also polychlorinated biphenyls(PCBs)and hexachlorobenzene(HCB)as unintentionally produced POPs(UP- POPs).This might result in an increased request for emission monitoring of PCDD/PCDF and other UP-POPs. Furthermore one aim of the Stockholm Convention is to continuously reduce and where feasible to eliminate UP-POPs in the next two *** the convention aims in destruction of POPs stockpiles and POPs remediation *** activities will request a strict emission monitoring including PCDD/PCDF, PCBs and other *** the question arose if all listed UP-POPs can be monitored by the AMESA system under the standard application(XAD2,30℃,4 weeks sampling duration)or ifa modification of the sampling system would be necessary.

Campylobacter continues to be a major cause of bacteriamediated diarrheal diseases, both for Thai citizens and travelers to Thailand. For field epidemiological studies, appropriate methods for storage, intralaboratory transport of patients specimens and use of enrichment culture to isolate this organism is critical. Study A, represents patient stool specimens collected in Bangkok and processed for Campylobacter culture within three hours after collection. Study B, represents stool specimens collected from patients in northeast and Southern regions of Thailand in modified CaryBlair transport medium. These specimens were transported and processed for Campylobacter in Bangkok at varying intervals ranging from 1 to 7 days. Of 900 diarrheal samples examined in study A, a total of 158 were Campylobacter positive through culture. Of these, 145 and 141 isolates were cultured by direct plating and enrichment plating respectively (P = 0.5839). From 1,168 diarrheal stool samples examined in study B, 184 were positive for Campylobacter. Direct and enrichment plating resulted in 139 and 168 culture isolates;respectively (P = 0.0003). Samples from study B delayed in processing for 1 to 3 days, resulted in 46 and 50 isolated by direct and enrichment plating;respectively (P = 0.4545). However, among samples delayed in processing for 4 to 7 days, a total of 128 Campylobacter isolates were cultured, having cultured 93 and 118 isolates through direct and enrichment plating;respectively (P = 0.0003). At present these studies demonstrate that enrichment culture has no benefit when stool specimen collection and immediate processing occur and when there is a processing delay period of 1 - 3 days. However, enrichment culture was beneficial in instances where transport and processing was delayed 4 - 7 days.
