暴露于交通污染物的户外工作者显示出更高水平的N-1,3-二甲基) -N'--p-phenylenediamine (6PPD-Q). 在户外工作者中,高6PPD-Q与增加的肝病变和改变的代谢和免疫标志物有关.
科学领域:
- 环境健康 环境健康
- 毒理学 毒理学 毒理学
- 职业医学 职业医学是专业的.
背景情况:
- 交通污染物对户外工作者造成健康风险,特别是肝病.
- N-(1,3-二甲基) -N'--p-phenylenediamine (6PPD) 和其代谢物6PPD- (6PPD-Q) 是新出现的环境污染物.
- 6PPD和6PPD-Q暴露对人类健康的影响尚不清楚.
研究的目的:
- 调查6PPD和6PPD-Q在室外和室内工人的分布.
- 评估6PPD/6PPD-Q暴露与各种生理参数,包括肝功能和代谢概况之间的关联.
- 为了确定与6PPD-Q暴露相关的肝损伤风险.
主要方法:
- 招募室外和室内工作人员进行血清和尿液样本采集.
- 在生物样本中分析6PPD和6PPD-Q度.
- 对23个生理参数的评估:血细胞计数,肝功能,功能,血糖和脂质概况.
- 计算机断层扫描用于肝损伤评估和后勤回归用于风险分析.
主要成果:
- 与室内工作者相比,户外工作者表现出明显更高的6PPD和6PPD-Q血清度.
- 户外工作者表现出总胆红素,间接胆红素和其他生化参数的水平升高.
- 在户外工作者的60%和室内工作者的30%中观察到肝脏病变.
- 血清6PPD-Q与免疫细胞计数,总胆红素,间接胆红素和甘油三素正相关.
- 每增加1微克L-1的血清6PPD-Q,肝病变的风险增加了2.31倍.
结论:
- 户外职业暴露与较高的血清6PPD-Q水平有关.
- 增加的6PPD-Q可能会对葡萄糖和脂质代谢产生不良影响.
- 血清6PPD-Q是暴露人群中肝损伤和免疫失调的潜在危险因素.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
Primary Symptoms of COPD:
Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow
Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test
Pharmacogenetics of Phase II Enzymes: N-acetyltransferase, Thiopurine S-methyltransferase, UDP-glucuronosyltransferase
