Sarin Induced Lung Pathology and Protection by Standard Therapy Regime

The effects of atropine, diazepam and pralidoxime were studied for their ability to block the pathological lesions induced by sarin. Rats were exposed to an aerosol of sarin at a concentration of 51.2mg-m for 15 min following the pretreatment with one of the following combinations: atropine (10 mg/kg, i.m.) and diazepam (0.5 mg/kg, i.m.); atropine and pralidoxime (25 mg/kg, i.m.); diazepam and pralidoxime; atropine, diazepam and pralidoxime. Lung exposed to sarin aerosols revealed an increased cellular proliferation with progressive diffused interstitial thickening on the 4th day following exposure. On the 16th day, loss of alveolar space and consolidation of large areas of all lobes were observed. Sarin also caused damage to the respiratory bronchioles. All the therapy regime blocked the development of lung lesions in the descending orders: atropine, diazepam and pralidoxime, atropine and diazepam > diazepam and pralidoxime > atropine and pralidoxime. The result suggests that diazepam in combination with atropine and pralidoxime could be an effective drug combination regime for the lung lesions.

The State Environmental Protection Standards Planning During 11^(th) Five-Year Plan (2006-2010)

This planning is stipulated to reinforce Decision by State Council onReinforrcing Environmental Protection with Views of Scientific Development, to give impetus to theenforcement and supervision along legal, standardized and scientific lines, to strengthenwell-structured laws and regulations for environmental protection, to improve the system oftechnical laws, regulations and standards for environmental protection, scientifically establishenvironmental standards and to dovetail environmental protection standards and targets. PresentSituation and Problems Concerning State Environmental Protection Standardization System PresentSituation of State Environmental Protection Standardization System China''s environmental protectionstandardization started side by side with environmental protection. The year 1973 witnessed China''sfirst environmental protection stand ard-Trial Standard of Industrial ''Three Wastes'' Discharge.After the development of over three decades, China''s environmental protection standard system,composed of national and local scales, has begun to take shape. National environmental protectionstandards range from environmental quality standard, pollutant discharge and control standards,standard sample, industrial standard for environmental protection, to other standards.

Discussing the development of domestic and foreign fire protection technical regulation and fire protection technical standard systems

This paper reviews the composition, development, and operation mechanism of domestic and foreign fire protection technical regulations and standards. Considering the development and problems of China's fire protection standard system and fire protection technical standards, this paper recommends fire safety professional engineering design specialization, suggests key research fields pertaining to fire protection technical standards, and elucidates how a performance-based fire protection technical standard system can be established.

Research on the Impact of Distributed Generation on Relay Protection and Its Standards

Distributed generation(DG) will change characteristics of power flow and faults of traditional distribution network as well as the network operation mode, especially the operation of relay protection and automatic circuit breaker re-closing. In this paper, the characteristics and influences of several types of distributed generation and connection pattern, relay protection and automatic circuit breaker re-closing are analyzed. Standards of relay protection when distributed generation access to distribution network are discussed as well.
