Abstract

This research evaluated antidibetic potential of methanolic leaves extracts of Khaya anthotheca in streptozotocin induced albino rats. Khaya anthotheca a member of Meliaceae family is traditionally used for treating several ailments. Diabetes is a chronic condition that develops when the pancreas is unable to secrete sufficient amounts of insulin or when the body fails to utilise the insulin that is produced. The leaves were harvested in Sukundi road Wukari and air dried for four weeks, the leaves were pulverized into powder using manual blender and stored in an air tight container. Extraction was done with absolute methanol; the extract was filtered using mesh and the filtrate was concentrated at 68oC. two grams of the filtrate were used for the study; the remainder was used to treat the animals. Using 40 mg/kg body weight of streptozotocin, the animals were divided into 5 groups of 4 each. Following a fourteen-day course of treatment, the animals were sacrificed; the blood was drawn through heart puncture and tested for blood sugar using a glucometer. One-way analysis of variance (ANOVA) was used for statistical analysis. Result of blood sugar level showed significant reduction in all the test groups (p<0.05) except group 2 which showed no significant reduction when compared to the normal control. Conclusion: This study therefore suggests the use of Khaya anthotheca as a diabetic agent and for treatment of diabetes. Further studies are needed to discover the bioactive constituent of the plant responsible for this anti-diabetic activity as well as other pharmacological activities in clinical trials.

Abstract

In this article, we investigate how the distribution of community participation impacts biodiversity conservation in national parks. This study analyzes factors that influence the distribution of community participation in biodiversity conservation. We hypothesize that employment in tourism increases the likelihood of community participation in biodiversity conservation. Additionally, we hypothesize that financial benefits derived by local people uniquely influence their likelihood of engaging in conservation activities. Furthermore, we hypothesize that infrastructure development affects household likelihood to engage in biodiversity conservation. Data were collected from households using questionnaires. Using logistic regression analysis, we find support for our hypotheses. The results suggest that local community participation in biodiversity conservation is significant. This study contributes to the growing empirical evidence on the effects of local community participation on biodiversity conservation in national parks and its implications for park managers and policymakers. Our study makes significant contributions to the existing literature and has practical implications for park management and policy formulation.

Abstract

This paper assesses the development and benefits derived by rural communities in the study area surrounding a game reserve. Questionnaires were administered to residents of fourteen selected communities within the game reserve and to the staff of the park. Additionally, focus group discussions were conducted with ten residents from each of the fourteen rural communities. A total of 720 questionnaires were distributed to residents to evaluate the development and benefits received from the establishment of the game reserve, while 250 questionnaires were distributed to the park staff to determine the impact of NGO activities on the communities. Interviews were also conducted with key stakeholders, including ward-heads, village-heads, youths, and women leaders. The findings reveal that the primary developments and benefits received by the game reserve rural communities include the establishment of primary schools, clinics, health centers, construction of roads and culverts, drilling of boreholes and wells, and access to loans for income generation. However, the relationship between farmers and pastoralists is strained, particularly during the dry season when livestock damage crops due to scarce forage. It is recommended that the working relationships between the communities and the game reserve be improved to achieve the overall objectives of conservation programs in Nigeria.

Globally, it has been deducted that the adult population with diabetes will rise by 69% for the year 2030. Thus, Bucholzia Coriacea (B. Coriacea) a perennial plant belonging to the family capparidaceae and genus Bucholzia is popularly known as wonderful kola. It’s also known as wonderful kola, its other name is called Garcinia kola .it has a long history of use in west Africa and central Africa, thus, the study on evaluation of potential in wonderful kola (buchiolizia coreica) seed extract on streptozotocin induced type 2 diabetes in male wister rats. Material and Methods: Fresh seeds of B. coriacea were plucked and washed with distilled water, the filtrate was concentrated using rotary evaporator and water bath. The extract was then weighed and stored in a refrigerator. 100g of crude extract and 1000mg of metformin was properly dissolved in 10ml of distilled water. The rats were carefully selected and separated into cages. 7 albino rats were used for normal control while 4 rats were kept in each of the remaining cages, and 6 replications were obtained, the test was carried out carefully by injecting the alloxan into the rats intraperitoneally and infecting them with diabetes mellitus, the following sets were made: normal group, negative and positive control group, while three groups were for extracts dosage. With exception of the normal control, all the groups were induced with diabetes. The extract (stem bark of Mangifera indica) will be administered orally to the three set of groups separately (i.e., one extract to one set). Determination of Fasting Blood Glucose Level by Intestinal Glucose Absorption. Results: Treatment groups receiving methanol Wonder Kola seed extract showed varying degrees of improvement in these parameters compared to the negative control group. Notably, Group VI, receiving the highest dose of the extract, demonstrated the most significant reduction in urea levels, suggesting a potential protective effect on renal function. The study investigated the effects of Wonder Kola seed extract on serum electrolytes, urea, and creatinine levels in alloxan-induced diabetic albino rats. Notably, significant variations were observed in these biochemical parameters across the different treatment groups. The study assessed the effects of methanol Wonder Kola seed extract on liver enzymes (AST, ALT, ALP) and serum protein levels (total protein, albumin, total bilirubin, direct bilirubin). Significant variations were observed in these parameters among the treatment groups compared to the normal and negative control groups. Treatment with the extract led to notable reductions in liver enzyme levels, indicating potential hepatoprotective effects. Conclusion: The findings of this study demonstrate the potential pharmacological benefits of methanol Wonder Kola seed extract in managing diabetes mellitus and associated complications.
