Spathodea campanulata Beauv. is an important plant widely used in traditional medicine for the treatment of hepatic disease. In the present study, we evaluate the phytochemical composition and hepatoprotective potential effect of the stem and root bark extracts of Spathodea companulata on dimethylnitrosamine (DEN) induced hepatic impairment in albino rats. Phytochemical compositions were analyzed using standard protocols. Forty-five male rats were grouped into 9 (A-I) of 5 rats each. Groups A-F were treated with stem bark extract, root bark extract, quercetin, DEN + stem bark extract, DEN + root bark extract, DEN + quercetin respectively while groups G-1 serve as control groups and were treated with corn oil only (Vehicle control), DEN only (Toxicant control), and distilled water (normal control) respectively. DEN was given at 25 mg/kg b.w., i.p on a weekly basis while all treatments were administered at 100 mg/kg BW orally for 60 days. Serum transaminase activities, body weight, and liver body weight ratio were evaluated. Results revealed the presence of alkaloids, cardiac glycoside, saponins, anthraquinone, steroids, and flavonoids in stem bark extract of Spathodea companulata, while the root bark contains cardiac glycoside, saponins, anthraquinonoid, steroids, and flavonoid. The DEN non-treated rat exhibited significant (p<0.05) weight loss and increase serum alanine transaminase (ALT) and aspartate transaminase (AST) activities when compared with the normal control. Treatment with stem and root bark extracts of Spathodea companulata significantly ameliorated the toxicant induce alterations in the transaminase activity and body weight loss when compared with the DEN nontreated rats. In conclusion, this study provides scientific validation of the use of this plant in traditional medicine for the management of hepatic disorders

Aim: In this study, the methanol stem bark extract of Detarium microcarpum was evaluated for sub-chronic, biochemical and histopathological studies. Methodology: Sub-chronic toxicity studies was investigated in rats administered with 35, 70 and 140 mg/kg doses of the extract orally for 28 days using standard laboratory procedures after the acute toxicity was carried out. Results: The median lethal dose (LD50) of the extract was calculated to be equal to (≥) 5000 mg/kg body weight in rats orally. Serological studies revealed significant (p<0.05) decrease in Alanine aminotransferase (ALT) at all doses tested, while at 140 mg/kg it caused a significant (p<0.05) increase in Alkaline Phosphatase (ALP). At doses of 70 and 140 mg/kg there was a significant (p<0.05) reduction in creatinine level. Histopathological studies on the liver showed moderate hepatocellular necrosis at doses of 35 and 70 mg/kg, while at 140 mg/kg there was intense hepatocellular necrosis,  Kupffer cells and lymphocytes hyperplasia. The Kidney showed intense necrosis of tubules and glomerular necrosis with lymphocytes hyperplasia at all doses tested.  The spleen also showed intense lymphocyte hyperplasia at all doses with sinusoidal congestion at the lowest dose of 35 mg/kg. The heart showed slight necrosis of cardiac muscle cells at all doses with blood congestion at 35 and 70mg/kg body weight. Conclusion: The study indicates that prolong use of the extract in the management of disease conditions may be associated with some adverse effect of some vital organs.

Diabetes is growing public health. The research investigated the modulatory roles of the aqueous stem-bark extract of Moringa oleifera on glucose utilization. A modified Oral Glucose Tolerance Test (OGTT) was used in studying the effect of the extract on glucose absorption, on four groups of six rats and standard methods were used to test the effect of the extract on enzyme activities (hexokinase and glucose 6 phosphatase) on three groups of six rats. In OGTT, rats in group-1(diabetic control) and group-4 (normal control) were administered with the vehicle only. The other groups were administered different concentrations of the extract in the vehicle (group-2 and 3 were 200mg/kg body weight and 300mg/kg respectively). In the enzymes activities, 200mg/kg body weight of the extract was administered to diabetic treated group whereas normal untreated and diabetic untreated received 5ml of water only. Glucose concentrations of OGTT showed increased concentration in the first 30 minutes after administration of the extract and steady time-dependent decreased concentration through 120 minutes. Group-3, showed a significant difference in each 30 minutes interval, compared to the 120 minutes (p<0.05). Each interval is significantly different from the preceded 30 minutes interval (p<0.005). Group-2 was significantly different in the first and second 30-minutes intervals, compared to the preceded interval (p<0.005). The first 30 minute interval was significantly different from the baseline and 120 minutes (p<0.05). In enzyme activities, the diabetic treated and normal untreated were significantly different from the diabetic untreated (p<0.05). The extract improved glucose utilization.

The aim of this study was to evaluate the safety profile of Combretum hypopilinum stem bark extracted with Methanol (70%v/v). Preliminary Phytochemical screening of the crude methanol stem bark extract was carried out, and revealed the presence of secondary metabolites such as steroids, flavonoids and alkaloids. Initial oral acute toxicity test was carried out using the Limit Dose Test to ascertain the safety of the extract in rats. Sub-acute toxicity testing was conducted by 28 days oral administration of 400 mg/kg, 800 mg/kg and 1600 mg/kg body weight to three groups of ten rats. The fourth group was administered distilled water 10 ml/kg. No major changes were observed in body weight of the animals following 28 days of daily oral administration. Biochemical parameters such as Total Protein, Total Bilirubin, Creatinine, Aspartate Transaminase (AST) and Alanine Transaminase (ALT), were found to be within normal ranges. The levels of marker enzymes in the vital organs did not show any significant changes between control and treated groups. Histopathological examination of the major vital organs (liver, brain, and kidney) revealed no significant pathological changes in the treated groups of rats. The results of the present work suggested that the methanol stem bark extract of Combretum hypopilinum is relatively safe for use at the tested doses.

Epilepsy is among the most common serious neurological disorders and affects around 50 million people worldwide, 80% of which live in developing countries. Despite the introduction of several new Anti-Epileptic Drugs (AEDs) in the last two decades, one third of treated patients have seizures refractory to pharmacotherapy. This highlights the need to develop new treatments with drugs targeting alternative seizure-induction mechanisms. Traditional medicine (TM) is used for the treatment of epilepsy in many developing countries and could constitute an affordable and accessible alternative to AEDs, but a lack of pre-clinical and clinical testing has so far prevented its wider acceptance worldwide. In this study we used Drosophila melanogaster paralyticbangsensitive(parabss) mutants as a model for epileptic seizure screening and tested, for the first time, the anti-seizure effect of a non-commercial AED. We evaluated the effect of the African custard-apple, Annona senegalensis, which is commonly used as a TM for the treatment of epilepsy in rural Africa, and compared it with the classical AED phenytoin. Our results showed that a stem bark extract from A. senegalensis was significantly more effective than a leaf extract and similar to phenytoin in the prevention and control of seizure-like behavior. These results support that Drosophila constitutes a robust animal model for the screening of TM with potential value for the treatment of intractable epilepsy.

Aim: Frankincense tree (Boswellia dalzielii) and Kenaf (H. cannabinus) are plants abundantly found in north-western Nigeria. These plants are very popular among the locals as potent sources of ethno medicine. The present study investigates the oral acute toxicity potentials of methanolic stem bark extract of frankincense tree and Kenaf leaves, as well as sub-chronic toxicity potentials of the plants extracts on the kidney and liver of Albino rats. Study Design: Laboratory-experimental design was used for this study. Place and Duration of Study: This study was carried out between September 2019 and November 2019 at Biochemistry laboratory, Sokoto State University, Sokoto, Nigeria. Methodology: For the oral acute toxicity study, the revised “Up and Down” test (Limit Dose Test) was used to determine the LD50 of the extracts. For sub-chronic toxicity study, twenty albino rats were used for each plant, and were divided into four groups of five animals each. Group I (control), Group II (received 200 mg extract/kg body weight), Group III (received 400 mg extract/kg body weight) and Group IV (received 800 mg extract/kg body weight). All administrations were given orally for 28 days. Liver and kidney markers were determined using standard methods. Result: The oral acute toxicity test of the plant extracts at 3000 mg/kg body weight showed no mortality for 24 hours and subsequent 14days of administration. LD50 for both plants is therefore greater than 3000 mg/kg. The result shows no significant differences (p > 0.05) on liver and kidney function biomarkers investigated when Group II, III and IV are compared with control. Conclusion: This suggests that Frankincense stem bark and kenaf leaves extracts may be safe in rats at doses less than or equal 3000 mg/kg.
