This study was carried out to investigate the sub chronic effects of oral administration of different doses: 100mg/kg, 400mg/kg, l600mg/kg, 6400mg/kg of aqueous extract of Khaya senegalensis in wistar rats. The rats were randomly separated to groups "A-G". The group "A" was considered as a non treated control. The other groups B, C, D and E respectively, were test groups and were treated with the extract. The biochemical and haematological parameters were assessed after 21 days of oral administration of the extract. The liver, kidney, pancreas, and heart of various experimental rats were harvested and preserved. The parenchymal tissues were fixed and using a microtome prepared to slides. Histopathological changes were observed using standard methods. There were no significant differences in white blood cell (WBC), Differential leucocytes count (DLC), haemoglobin concentration, packed cell volume (PCV) and Red Blood Cell count (RBC) respectively. There was however a significant (P<0.05) decrease in the serum Alanine amino transferase (ALT) in groups B, C and D and also a significant (p<0.05) decrease in AST levels in group B and E. The blood glucose levels also decreased significantly (P<0.05) in groups concentration in groups C, D, and E. Histopathological examination showed moderate degenerative changes and congestions in the livers and kidneys and pancreas in all treated groups. This gave an insiglht on the effects of oral administration of an aqueous extract of Khaya senegalensis on the haematological and biochemical parameters, with the related tissue pathology, in experimental wistar rats. Conclusion could be made that care should be taken in prolonged administration of high doses of aqueous extract of  Khaya senegalensis man and animals.

Background: This study investigated the potential antioxidant effects of aqueous extract of the stem bark of Theobroma cacao L. in Wistar rats. Methods: Twenty Wistar rats weighing between 126 g – 224 g were grouped randomly into 4groups of 5 rats each. Group 1 served as control and received water while groups 2, 3 and 4 rats were given 1000mg/kg, 3000mg/kg and 5000mg/kg b.wt of the extract respectively for 28days. On the 29th day, the rats were anaesthetized and blood samples were collected for analysis of some haematological parameters, enzymatic and non- enzymatic antioxidant activities. Results: The results obtained showed that there was significant increase (p<0.001) in SOD, Catalase activities and MDA levels in a dose dependent manner. The results also showed significant increase (p<0.001) in RBC Group 2, 3 and 4 rats when compared to the Group1. Significant increase was also observed in Hemoglobin (Hb) and Hematocrit (Hct) level in group 2 and 3 rats (p<0.001). Mean corpuscular volume was significantly increased in group 2 rats (p<0.001). Conclusion: The findings from this study showed the antioxidant and hematinic potentials of the stem bark of Theobroma cacao L.The aqueous extract of the stem bark of Theobroma cacao L. has a potential antioxidative and hematinic effects in Wistar rats. This is largely due to its rich phytochemical and nutritive contents. Further research work will be needed to see the possible application of these properties in humans.

Introduction: Khaya senegalensis is a genus of seven species of trees in the mahogany family Meliaceae, native to tropical Africa and Madagascar. Mahogany  in  English, Aganwo  in  Yoruba,  Madachi  in  Hausa  and  Ono  in  Igbo. All species become big trees 30–35m tall, rarely 45m, with a trunk over 1 m trunk diameter, often buttressed at the base. The leaves are pinnate, with 4-6 pairs of leaflets, the terminal leaflet absent; each leaflet is 10–15 cm long abruptly rounded toward the apex but often with an acuminate tip. Aim: The  aim of  the study  was  to determine  the Toxic  effect of prolonged oral administration  of  the  aqueous stem bark of  Khaya senegalensis extract  on the histology of  Kidneys and its biochemical parameters in wistar rats. Methods: This work is an experimental research. A total of 20 wistar rats were randomly divided in to 5 groups each of which consist of 4 rats. Group 1 received distilled water to serve as control while group 2, 3, 4, and 5 received 500 mg/kg bw, 1000 mg/kg bw 2000 mg/kg bw  and 4000 mg/kg bw of the aqueous extract respectively for 60 days after which they were sacrificed, processed in Automatic Tissue Processor machine, Sectioned and stained with H &E. Results: There was statistical significant increase in urea and potassium in all the test groups but is not dose dependent. The creatinine was significantly increased in groups 2, 4 and 5. While other parameters such as sodium, chloride and bicarbonate no significant difference when compared to the control group. The kidney sections showed normal structure in group 1 when compared with the test groups. However, there was significant infiltration of inflammatory cell across all the groups which were suggestive of kidney damage or injury. Similarly phenomenon was noticed in group 5 with additional congestion in the glomerulus and more polymorphs seen. Conclusion: The LD50 was found to be greater than 5000 mg/kg bw, therefore, 400 mg/kgbw was used as higher dose in the experimental wistar rats. There were statistical significant increases in some parameters groups while some groups not significant. The kidney section showed significant infiltration of polymorphs across all the groups more marked in group 5 with distension and damaging of the glomerulus indicating renal injury.
