Research ArticleOpen accessIn the abstractInvolvement of Microsomal Na+/K+ ATPase Activity in the Mechanism of Action of Dopaminergic D2 ReceptorsAbdulrahim Abu-JayyabProblem statement: Our previous research has shown that mitochondrial ATPase may have a role in the action of dopaminergic D2 receptors. It is therefore, thought of interest to investigate the effect of bromocriptine, sulpiride or their combination on the mitochondrial and microsomal ouabain sensitive and ouabain insensitive Na+/K+-ATPase in the liver of rats. Approach: In vivo treatment was carried out … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 4 · 31 Dec 2009 · 6,971 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBiological Control of Rice Blast (Magnaporthe oryzae) by use of Streptomyces sindeneusis isolate 263 in GreenhouseM. Ebrahimi Zarandi, G.H. Shahidi Bonjar, F. Padasht Dehkaei et al.Soil Actinomycetes particularly Streptomyces spp. have antagonistic activity against wide range of plant pathogens. In the recent decades they have attracted high interests as biocontrol agents. In search for finding such principles, in vitro suppression of Magnaporthe oryzae the causal agent of rice blast disease was studied by use of Streptomyces sindeneusis isolate 263 in greenhouse. Spray of rice seedling-leaves … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 11,492 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSerotonergic Properties of the Roots of Clerodendron capitatumSiddig Ibrahim Abdel Wahab, Abdel Wahab Hassan Mohamed, Osama Yousif Mohamed et al.The aim of this study is to investigate the pharmacological effects of the methanolic extract of Clerodendron capitatum, CC, (family verbenaceae). These investigations were carried out on isolated frog rectus abdominus muscle and rabbit aortic strips and jejunum and non-pregnant rat uterus pretreated with oestradiol. Results showed that CC did not demonstrate any contracting, relaxant or blocking effects on frog … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 7,847 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordNaloxone benzoylhydrazone activates Extracellular Signal-Regulated Protein Kinases and modulates Nociceptin Opioid Peptide Receptor activityDeepak R. Thakker, Ghazi F. Altememi, Chitra D. Mandyam et al.Naloxone benzoylhydrazone (NalBzoH) is often used as a nociceptin opioid peptide (NOP) receptor antagonist. However, NalBzoH is also a mixed μ antagonist/κ and δ opioid agonist and its actions at the NOP receptor range from an antagonist to partial agonist, depending on the effector response/system studied. We now report that NalBzoH activates endogenously expressed κ3 opioid, but not NOP, receptors … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 2 · 30 Jun 2007 · 7,549 accessesView PDF Cite
