Zika virus is a mosquito-transmitted flavivirus belongs to family Flaviviridae which becomes the focus of an ongoing pandemic and public health emergency all around the world. Zika virus has two lineages African and Asian. Mosquito-borne flavivirus is thought to replicate initially in dendritic cell and then spread to lymph nodes and then to the bloodstream. Zika virus was initially recognized in Uganda in 1947 in Monkeys through a method that observed yellow fever. It was later distinguished in people in 1952 in Uganda and the United Republic of Tanzania. The explosions of the zika virus disease have been recorded in Africa, The Americas, Asia, and The Pacific. Gillian-Berre syndrome and congenital malformation (microcephaly) suspected to be linked with Zika virus. The virus can only be confirmed through laboratory test on blood or other body fluids, such as urine, saliva or semen. No specific antiviral treatment for Zika virus disease exists. Treatment is aimed at relieving symptoms with rest, fluid and medications. WHO/PAHO encourages the countries to establish and maintain Zika Virus infections, detection, clinical management and community assurances strategies to reduce transmission of the virus. The future of Zika Virus spreading to other parts of the world is still unknown. Keywords: Zika Virus, flavivirus, Mosquito, Vaccine, Treatment, Microcephaly, WHO/PAHO.
Background: Oxidative stress is imbalance between aggressive and defensive system. Overproduction of oxidative stress contribute in pathogenesis of many diseasesincluding Parkinsonism, Alzheimer diseases, apoptosis, hepatic fibrosis ,chronic kidney failure and liver steatosis etc . There are several OTC drugs including NSAIDs that generate oxidative stress when administered. So there is a need to explore about these drugs. Therefore this study was designed to evaluate the oxidative stress potential of Acetaminophen, acetyl salicylic acid and Celecoxib NSAIDs. Objective: The present study is design to investigate the oxidative stress of NSAIDs of acetaminophen, aspirin and Celecoxib drug with reference to the hydrogen peroxide. Material and method: The Experimental protocol was designed for estimate the level of oxidative stress in NSAIDs treated animals against hydrogen peroxides. Animal of control group received only vehicle throughout experimental protocol. Rats of AAP group, ASA group ,CX group were exposed to acetaminophen (150mg/kg; orally) acetyl salicylic acid (300mg/kg ;orally) and Celecoxib (50mg/kg; orally) for forty two days . Rodent of HP group were challenged with Hydrogen peroxides (0.5%) with same schedule as above. At end of experimental protocols, all the animals were sacrificed and their organ were identified and collected for oxidative stress estimation and histological examination. Result: NSAIDs administration caused increase in oxidative stress measured in terms of SOD, CAT, MDA, GSH and GPx. HP administration produced maximum oxidative stress compare to all other groups. Oxidative parameter i.e. SOD, CAT, GSH and GPx were found to be decreased as compare to control rats. However MDA were found to be increased as compare to control rats. Additionally, CX produced less oxidative stress compare to other NDAIDs. Further, histological examinations support the biochemical results. Conclusion: From the above observations it can be concluded that NSAIDs have oxidative stress potential and generate oxidative stress and damage the organs when administrated chronically. Thus, these drugs should be used judiciously.
Pharmacovigilance outlined by the globe Health Organization (WHO) because the science and series of activities about the detection, evaluation, understanding rejection of adverse impact or Associate in Nursing different drug connected problem’ and a clinical test could be an analysis study in human volunteers to answer specific health queries. Fastidiously conducted clinical trials square measure quickest and safest thanks to realizing treatment that employment in individuals and thanks to improving health. Play a crucial role in guaranteeing that patient to be provided the safe drug. The Pharmacovigilance has been recognizing to play a crucial role in the rational use of the drug by providing data concerning the adverse impact possess by drug normally population. The information of drug Adverse Drug Reaction (ADRs) are often increased by numerous suggests that such information studies, intensive observation, spontaneous reportage and different new method at dictatorial and scientific level square measure being developed with the intention of step-up Pharmacovigilance. As a result of assessment strategies are not entirely void of individual judgments, integrator reliableness is often low. In conclusions, there's still no methodology universally accepted for casualty assessment of ADRs. Keywords: Adverse Drug Reaction, Clinical test, Pharmacovigilance, Treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
