暴露

The human exposure levels of formaldehyde and acetaldehyde in hospitals were discussed.

Results: Of the 709 interviewee, 574(80.96%) recognized rabies as a fatal disease, 156(22.00%) disregarded the threat posed by pet bites, 446 (62.91%) would seek medical assistance once bit, while 121(17.07%) reported treatment of wounds using improper, thumbnail approaches. Prevention was observed based on doctor's advices in all of 9 degree Ⅰ exposers (100.00%), 76 of 91 degree Ⅱ exposers (83.52%) and 32 of 212 degree Ⅲ exposers (15.09%).

结果：有80.96%(574/709)的被调查者知晓狂犬病是一种致死性疾病，22.00%(156/709)的被调查者对家养动物致伤表示无所谓、不用治疗的观点，认为只要致伤需就诊者占62.91%(446/709)，用土方法等不正确方法处理伤口者占17.07%(121/709)；100.00%(9/9)的Ⅰ级暴露者，83.52%(76/91)的Ⅱ级暴露者和15.09%(32/212)的Ⅲ级暴露者完全按照医嘱进行了预防治疗。

These two elaborate laboratories, ventilation/fire protection laboratory and exposure chamber, can be simulated as the occupational workplace. Students will have opportunities to gain the practical discipline within campus, such as fire scene examination, fire fighting tool use, fire protection system establishment, and exposure assessment etc. Three curricula have been compiled as a guide to assist students to get more understanding on the hazard identification within campus.

本校是全国唯一同时设有消防实习教室及暴露舱实习教室的学校，可模拟火灾发生时之情景，进行水雾系统操作、各种灭火工具使用、防火系统设置等实习教学活动，学生并可利用暴露舱室进行暴露空气中危害物质之体验教学，更能加深学生了解空气品质对健康危害之认知，同时在使用个人防护具的教学中，学生能有实作的机会，这是本教学方案最大的特色。

Results Live poultry husbandry covered 6657 households,and bird pet raising 113 households.

危险度评价内容包括：家禽养殖职业暴露、鸟类宠物暴露、活鸡购买暴露、禽流感预防知识知晓率、居民卫生习惯和自我保护行为和心理影响。

The degree of neuron damage after +10 Gz5 min exposure in pre-exposure groups with repeated +4 Gz3 min 3～5 times was obviously slight comparing with that of single +10 Gz exposure group.

Gz3 min反复暴露3次和5次，再暴露于+10 Gz5 min，其神经元损伤程度明显轻于+10 Gz5 min单次暴露。

However, unlike most industrial particles there are no exposure limits, such as Permissible Exposure Limit or Threshold Limit Value, established for biological agents such as SARS. Therefore, respirators are not a guarantee that the user will not contract SARS.

然而，和绝大多数工业环境中存在的颗粒状污染物不同的是，SARS病毒并没有暴露限值，因此，佩戴防护口罩虽然能够帮助降低其暴露水平，却无法保证使用者绝对不接触SARS病毒，即不排除存在暴露的可能，不排除受感染，生病甚至死亡的可能。

然而，和绝大多数工业环境中存在的颗粒状污染物不同的是，微生物，如甲型（H1N1）流感病毒没有暴露限值，如职业接触限值，因此，虽然佩戴呼吸防护口罩能够帮助降低暴露水平，却无法保证使用者绝对不接触甲型（H1N1）流感病毒，不排除存在暴露的可能，不排除受感染、生病甚至死亡的可能。

Separate under the SMAS to 2.0 cm above the supraorbital edge and 1.5 cm above zygomatic arch, where the periosteum and superficial layer of deep temporal fascia were incised to expose fracture;②Separate under the SMAS to the supraorbital edge and zygomatic arch, and then as in method Ⅰ, incise at 2.0 cm above the supraorbital edge and 1.5 cm above zygomatic arch to expose fracture.③ As in method 2, separate under the SMAS to the supraorbital edge and zygomatic arch, and then incise the periosteum directly to expose fracture.

对27例面中部骨折行头皮冠状切口患者分别采用，方法Ⅰ：沿SMAS下分离至眶上缘上2cm处和颧弓上1.5cm处，先在此切开骨膜和颧深筋膜浅层，分离暴露骨折；方法Ⅱ：沿SMAS下分离至眶上缘和颧弓处，然后再在眶上缘上2cm和颧弓上1.5cm切开直至暴露骨折；方法Ⅲ：同方法Ⅱ分离至眶上缘及颧弓处并直接切开骨膜，暴露骨折。

Compaired with group HG, the expression of CaM showed an increased trend in group CHG. 4. Intracellular calcium concentration could be elevated resulted from noise exposure.

声暴露后毛细胞内游离Ca~(2+)浓度升高，直接损伤暴露组毛细胞内游离Ca~(2+)浓度明显高于噪声习服组和噪声习服后损伤暴露组。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。
