This study was designed to determine the effect of Carica papaya L. stem bark extracts on cholesterol concentration in rats induced with glibenclamide. A completely randomized design was used for the experiment which consisted of 6 treatment groups, each group consisted of four rats, as follows:1) KN (negative control, non-diabetic rats); KP, diabetic rats given glibenclamide 10 mg/kg body weight; EP 1, diabetic rats given 0 mg/kg body weight/day extract; EP2, diabetic rats given 100 mg/kg body weight/day extract; and EP3, diabetic rats given 200 mg/kg body weight/day extract, EP4, diabetic rats given 300 mg/kg body weight/day extract for 28 day. The results showed that C. papaya L. stem bark extract decreased (P<0.05) cholesterol levels in diabetic rats. It was concluded that C. papaya L. stem bark extract had potential as anti-hypercholesterolemic in diabetic rats.

Abstract Background Burkea africana is a widely used medicinal plant in folkloric medicine in many developing countries of the world. It is useful in the treatment of various ailments including hepatitis, jaundice, diarrhea, stomach aches, abscesses, oedema, epilepsy, bloody diarrhea, gonorrhea, syphilis, toothaches and poisoning. Nevertheless, there are little or no scientific evidence to substantiate this medicinal claim by traditional healers. Burkea africana stem bark was therefore, investigated for its protective or stabilizing effect on erythrocyte membrane in acetaminophen-treated rats. B. africana stem bark was extracted using 80% methanol. Erythrocyte stabilizing effect was studied using erythrocyte osmotic fragility (EOF) test. Thirty (30) male rats were randomly assigned into five (5) groups of six (6) rats each. Groups 1 and 2 served as normal control and negative control (acetaminophen-treated group) respectively. Groups 3, 4 and 5 were pretreated with methanol stem bark extract of Burkea africana (MSBEBA) at doses of 200, 400 and 600 mg/kg body weight respectively once daily for seven (7) days. Blood samples were collected from the animals in all the groups on the 8 day for evaluation of packed cell volume, haemoglobin, red blood cell, white blood cell counts, and differential white blood cell count as well as erythrocyte osmotic fragility. Results The erythrocyte osmotic fragility test showed that there was a significantly (p < 0.05) low percentage hemolysis in the groups pre-treated with the extract when compared with the negative control. The percentage hemolysis was least at 600 mg/kg body weight of the extract. There was also a significant (p < 0.05) increase in the packed cell volume, haemoglobin, red blood cell count at all the doses of the extract used. Neutrophils were significantly (p < 0.05) decreased while lymphocytes were significantly increased in the groups administered MSBEBA 400 and 600 mg/kg body weight. Conclusion Methanol stem bark extract of Burkea africana had protective effect on the red blood cells and also improved haematological parameters. This indicates that Burkea africana may be useful in the treatment of disease conditions that results in hemolytic anemia by stabilizing red erythrocyte membranes and enhancing erythropoiesis.

Stem Bark Extract

Many modern medicines are derived from the chemicals available in plants. The utilization of plants against diseases by traditional medical practitioners is common in many parts of the world and several researches have been carried out to determine the scientific basis for the use of such plants. Alstonia boonei is one of the many medicinal plants found in Nigeria. The plant parts have been traditionally used to treat various ailments including malaria. This study was carried out to evaluate the antimalarial activity, phytochemical composition and toxicity of ethanolic stem bark extract of Alstonia boonei. The extract showed substantial dose dependent antimalarial activity as indicated by the recorded suppressive (45.67%, 58.53% and 74.68% for 100, 200 and 400 mgkg-1 body weights) prophylactic (33.57%, 45.64% and 61.23% for 100, 200 and 400 mgkg-1 body weights) and curative effects (62.35%, 68.57% and 79.63% for 100, 200 and 400 mgkg-1 body weights) on Plasmodium berghei infected white albino mice. The results of the antimalarial tests were significantly different compared to the negative control at P < 0.05. The phytochemical evaluation showed that the plant contained important chemical compounds including tannins, flavonoids, steroids, phenols, alkaloids, saponins, glycosides and terpenoids. The acute toxicity test showed that the extract is safe as observed on the tested mice. It was concluded that the extract contains important active antimalarial compounds that are safe and should be further investigated for antimalarial drug development.

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.
