Professor Iwu And His Bitter Kola Science by omongbatim: 2:50pm On Aug 20, 2014 |
No doubt Prof Iwu could arguably be described as the most accomplished biomedical scientist living and operating from Nigeria. If we overlook his failed foray into politics we can appreciate how much he has come in the area that he has his greatest strength: ethno-phamarcy. Working with national and international colleagues, he has co-authored well over Bleep papers some as recent as 2012 like the one below 5-HT2A/C receptors mediate the antipsychotic-like effects of alstonine By:Linck, VM (Linck, V. M.)[ 1,2 ] ; Bessa, MM (Bessa, M. M.)[ 1 ] ; Herrmann, AP (Herrmann, A. P.)[ 1,2 ] ; Iwu, MM (Iwu, M. M.)[ 3 ] ; Okunji, CO (Okunji, C. O.)[ 3 ] ; Elisabetsky, E (Elisabetsky, E.)[ 1,2 ] PROGRESS IN NEURO-PSYCHOPHARMACOLOGY & BIOLOGICAL PSYCHIATRY Volume: 36 Issue: 1 Pages: 29-33 DOI: 10.1016/j.pnpbp.2011.08.022 Published: JAN 10 2012 View Journal Information Abstract The purpose of this study was to determine the effects of alstonine, an indole alkaloid with putative antipsychotic effects, on working memory by using the step-down inhibitory avoidance paradigm and MK801-induced working memory deficits in mice. Additionally, the role of serotonin 5-HT2A/C receptors in the effects of alstonine on mouse models associated with positive (MK801-induced hyperlocomotion), negative (MK801-induced social interaction deficit), and cognitive (MK801-induced working memory deficit) schizophrenia symptoms was examined. Treatment with alstonine was able to prevent MK801-induced working memory deficit, indicating its potential benefit for cognitive deficits now seen as a core symptom in the disease. Corroborating previously reported data, alstonine was also effective in counteracting MK801-induced hyperlocomotion and social interaction deficit. Ritanserin, a 5-HT2A/C, receptor antagonist, prevented alstonine's effects on these three behavioral parameters. This study presents additional evidence that 5-HT2A/C receptors are central to the antipsychotic-like effects of alstonine, consistently seen in mouse models relevant to the three dimensions of schizophrenia symptoms.
