Research ArticleOpen accessEvery word in the titleAMELIORATIVE EFFECT OF HIBISCUS SABDARIFFA LINN ON SUBCHRONIC CHLORPYRIFOS-INDUCED ALTERATIONS IN SEX AND THYROID HORMONES IN MALE WISTAR RATSShittu Muftau, Olatunji Omobolanle Aisha, Suleiman Folorunsho Ambali et al.Studies have shown that Chlorpyrifos (CPF), an Organophosphate (OP) insecticide alters both sex and thyroid hormones. Apart from inhibiting Acetylcholinesterase (AChE) activity, CPF has been shown to cause oxidative stress. The antioxidant potentials of many flavonoid-containing plants are increasingly being exploited in the therapy of many infectious and non-infectious diseases. Hibiscus Sabdariffa (HS) is one of the most widely used … …American Journal of Pharmacology and Toxicology, Vol. 9, Issue 1 · 20 Feb 2014 · 9,097 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleVitamin C Alleviates Chronic Chlorpyrifos Induced Alterations in Serum Lipids and Oxidative Parameters in Male Wistar RatsS. F. Ambali, M. Shittu, J. O. Ayo et al.Problem statement: Although the increase incidence of cardiovascular diseases, obesity and diabetes mellitus has been attributed to changing life style, the role of environmental contaminants is currently being given considerable attention. Pesticides, including Organophosphate (OP) insecticides are one of the most pervasive environmental contaminants that are deliberately released into the environment. Chlorpyrifos (CPF), a widely used OP insecticide has been … …American Journal of Pharmacology and Toxicology, Vol. 6, Issue 4 · 21 Feb 2012 · 7,576 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleAntagonism Between Chlorpyrifos and Flaxedil in Toad and Earthworm Neuromuscular TransmissionYong-Chiang Chang, Amauri B. Bartoszeck, Samir A. Madeira, Charles I. AbramsonThe cholinesterase inhibition effect of chlorpyrifos, a commercial insecticide, was tested by its antagonism to the acetylcholine inhibition effect of flaxedil in 30 isolated nerve-sartorius muscle preparations of the toad, compared with its antagonism in 30 isolated nerve cord-body wall muscle preparations of the earthworm. Inhibition and facilitation in this antagonism were measured by changes in depolarizing rate of toad … …American Journal of Environmental Sciences, Vol. 2, Issue 2 · 30 Jun 2006 · 6,389 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleVitamin E Mitigates Chronic Chlorpyrifos-Induced Oxidative Changes in Pituitary Glands and Testes in Wistar RatsM. Shittu, J. O. Ayo, S. F. Ambali et al.Problem statement: The sperm counts of men have declined by about 50% in the last few decades. The contribution of environmental contaminants to this decline cannot be overemphasized. Pesticide is one of the most pervasive environmental chemical contaminants that have been of increased use due to the compelling need to feed the ever-growing world human and animal population and protect … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 19 Nov 2011 · 7,309 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNon-Target Inhibition of Antioxidant Enzymes in Honey Bees (A. mellifera and A. florea) Upon Pesticide ExposureAmal Ahmed Berjawi, Syed Salman Ashraf, Mohammad Ali Al-DeebUnderstanding how different insecticides influence bee health is very essential. The aim of this work was to evaluate enzyme kinetics and inhibition by insecticides in Apis mellifera and Apis florea. Tested enzymes showed variable affinity to substrates. In A. florea, glutathione S-transferase (GST) showed significantly higher affinity for its 1-Chloro-2,4-Dinitrobenzene (CDNB) substrate than in A. mellifera. Carbosulfan caused the highest … …OnLine Journal of Biological Sciences, Vol. 20, Issue 2 · 10 Apr 2020 · 7,394 accessesView PDF Cite

M. Eltayeb, Guo-An Zhang, Jiu-Gao Xie, Feng-Yu MiProblem statement: The toxicity of seven of Allylisothiocyanate (AITC) formulations, AITC pure and in mixture with cypermethrin and chlorpyrifos, was evaluated using spray application and fumigation method against the diamondback moth, Plutella xylostella (L.), the small cabbage white butterfly, Pieris rapae (L.) and the tobacco cut worm, Spodoptera litura Fabr. Approach: Response varied according to insect species, specific formulation and … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 6,988 accessesView PDF Cite
