Toxicology of nonsteroidal antiinflammatory drugs   总被引:1,自引:0,他引:1  
Nonsteroidal antiinflammatory drugs (NSAIDs) constitute a class of pharmacologically active agents with similar therapeutic actions and side effects, despite diverse chemical structures. NSAIDs inhibit the enzyme cyclo-oxygenase and, thus, decrease inflammation mediated by prostaglandins. Toxicoses due to NSAIDs are manifested primarily by gastrointestinal upset and hemorrhage and by renal damage. Management consists of detoxification measures, in addition to supportive and symptomatic care. The article outlines the incidence, clinical toxicity, mode of action, and pharmacokinetics of nonsteroidal antiinflammatory drugs. The toxic effects of NSAIDs on individual organ systems are described, and general management recommendations for the treatment of NSAID toxicoses are presented.  相似文献

Hundreds of different household cleaning products are available in homes, presenting potential hazards to pets. These products are complex mixtures of chemicals that vary widely in their toxic potential. Prevention of toxicoses in companion animals follows the same guidelines as those recommended for children: Keep cleaning products out of the reach of pets, do not leave open containers or solutions of cleaning products unattended where animals may get into them, make sure containers of cleaning products are tightly sealed and properly labeled, and dispose of any cleaning solutions promptly after use. If a companion animal has ingested or spilled a cleaning product or disinfectant on itself, it is very important to assess the potential hazard to the animal promptly. Many products contain warnings regarding the corrosive or irritation potential of the product and instructions on the label for preliminary action in the case of accidental oral, dermal, or ocular exposures in humans. These instructions can generally be followed initially until further information on the product can be obtained, although the recommendations on some product labels may be outdated. In general, the clinical management for toxicoses caused by cleaning products and disinfectants involves the prevention of further contact with the concentrated product through either dilution or bathing; emergency stabilization of the patient if clinical signs are present; instituting specific therapies, if available; and use of general supportive care.  相似文献

Wheat kernel size and shape influence its flour yield and market price. A hexaploid wheat population of 185 recombinant inbred lines was evaluated for five kernel morphometric traits namely, 1000-kernel weight, kernel length, width, length–width ratio and factor form density in two diverse agro-climatic regions in India in five to eight year–location combinations. Additive main effects and multiplicative interaction analysis revealed significant contributions from genotype (G) and genotype × environment (G × E) effects for these traits. Quantitative trait locus (QTL) analysis by composite interval mapping (CIM) was performed using a linkage map of 251 SSR markers and 59 QTLs distributed on 16 chromosomes were identified. The majority of the QTLs were located on the D genome (44.07%) and the homeologous chromosomes of Group 2 (38.98%). Stable QTLs detected in three or more year–location combinations were identified for four traits. Multi-trait CIM showed 10 chromosomal regions harboring putative pleiotropic loci. Complexity in the genetic effects was further revealed by QTL analysis based on mixed-linear model that indicated 19 QTLs with significant individual effects (main-effect QTLs) and 14 QTL × QTL interactions. Five of these nineteen main-effect QTLs and one of the fourteen QTL × QTL interactions showed environmental influence.  相似文献

In-vitro pediculicidal activity of Hedychium spicatum essential oil   总被引:1,自引:0,他引:1  
Jadhav V  Kore A  Kadam VJ 《Fitoterapia》2007,78(7-8):470-473
The essential oil extracted from rhizomes of Hedychium spicatum was evaluated for in-vitro pediculicidal activity. At 5%, 2% and 1% concentration the essential oil showed more significant activity than 1% permethrin based product.  相似文献
