It has been found that, ethanol and aqueous extracts of the plant leaves exert anti-diabetic effect on rats. This study investigated the effects of ethanol and aqueous leaf extracts of this plant on some hematological parameters and serum cholesterol level in Wistar albino rats. Intraperitoneal administration of ethanol and aqueous extracts of P. mildbraedii leaves at the doses of 200 and 400 mg kg-1, on two groups of rats for 28 days showed no adverse effects on the hematological parameters considered in this study. There was a significant (p < 0.05) dose dependent increase in almost all the hematological parameters. However, the serum cholesterol level was significantly reduced in rats exposed to both doses of the ethanol and aqueous extracts of the plant leaf as compared to the rats in the control group. These effects of the extracts increased with increased doses. These results suggest non-toxic effects of the leaf extracts of P. mildbraedii on the hematological parameters, as well as an ability to help in preventing cardiovascular diseases in the diabetics.   Key words: Pterocarpus mildbraedii, hematology, cholesterol, heart, packed cell volume, hemoglobin, toxicology.","PeriodicalId":7631,"journal":{"name":"African Journal of Biochemistry Research","volume":"98 1","pages":"28-33"},"PeriodicalIF":0.0,"publicationDate":"2017-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90801050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The contractility of the isolated rabbit ileum was recorded using kymograph. The effects of the crude extract of X. aethiopica on rabbit ileum were independently determined using a dose range of 10-8 to 10-4 mg/ml. However, to determine the effects of the extract on rabbit ileum in the presence of other agonist and antagonist a constant dose of 10-4 mg/ml of the extract was used. The result showed that the crude extract of X. aethiopica, nifedipine only and serotonin only produced a significant (p<0.001) dose dependent relaxation of the ileum muscle. Addition of the extract to nifedipine shifted the graph to the right. Administration of CaCl2 alone produce a dose dependent contraction of the rabbit ileum with negative correlation coefficient (p<0.001). Co-administration of CaCl2 with the extract shifted the CaCl2 response curve to the left.  Addition of extract to serotonin caused a significant (p<0.01) decreased in the relaxation of the rabbit ileum.
