ABSTRACT: The dried and pulverized leaves of Acalypha wilkesiana was reflux with distilled water. Studies were then undertaken on the effect of the aqueous extract on leucocytic count (WBC) and differential leucocyte count (DLC) on Mice graded doses (800mg/kg,1000mg/kg body weight) of the extract were administered orally to different groups of mice daily for 21 days and had a beneficial effects on the WBC and DLC. There was a significant (p<0.05) increase in leucocyte count when compared to control in all the days (7, 14 and 21). Differential leucocyte count also indicated a significant (p<0.05) increase while Lymphocyte indicated a significant (p<0.05) decrease.The prolong oral administration of the extract under the condition of this study shows that the extract may be toxic at higher doses. Nevertheless,the extract appeared to be more beneficial at lower doses and significantly (p<0.05) improves WBC and DLC values and this effect has potential application in stimulation of the immune pathway. This may seem to explain for its use as an antifungal and antibacterial agent in African traditional medicine.

Abstract: The phytochemical screening and the antibacterial activity of Tamarindus indica Linn was carried out. The result of the phytochemical screening revealed the presence of alkaloids, anthraquinones, glycosides, flavonoids, phlobatannins, reducing sugars, saponins and tannins.The extracts of the fruits and the leaves of Tamarindus indica were tested on Staphylococcus aureus, Escherichia coli, Salmonella typhi and Pseudomonas aeruginosa as test organisms. Agar well diffusion method and macro broth dilution method were employed in determining the zone diameter of inhibition (ZDI) and minimum inhibitory concentration (MIC) of the extracts respectively. Different concentrations of 50, 100, 250 and 500 mg/ml of the extracts were used for the antibacterial activity against the test organisms. The result revealed that the fruit extracts exhibited a higher antibacterial activity than the leaf extracts. The methanol fruit extract gave the highest zone diameter of inhibition of 411.0 mm for E.coli and 370.4 mm for S. typhi at 500 mg/ml while the methanol leaf extract gave 0.0 mm for E.coli and 250.4 mm for S. typhi at 500 mg/ml. The aqueous and methanol fruit extracts were effective against E. coli, S. typhi and P. aeruginosa. The ethanol extract was also effective against E.coli, S. typhi, P.aeruginosa and S.aureus. The leaf ethanol and methanol extracts were effective against S.typhi and P. aeruginosa. Generally, the fruit extracts exhibited a higher antibacterial activity than the leaf extracts but both are effective against the test organisms The result also shows that the extracts can inhibit and as well kill the test organisms indicated by their respective MIC and MBC values. These findings were compared with those produced by ampiclox, a reference antibiotic. The results were analyzed statistically using Chi-square at p = 0.05 level of significance T. indica can be harnessed to produce broad-spectrum antibiotics and can be a potential source of new classes of antibiotics that could be useful for infectious diseases caused by the test organisms.

Abstract: The study analysed the factors influencing revenue generation from gum arabic among its marketers in Jalingo Local Government of Taraba state, Nigeria. Sixty respondents were randomly interviewed using structured questionnaire, out of which 50 was used for this study. Gum arabic is one of the cash crops with high market value in world. This is due to its high demands worldwide. There are about 11 states in the country where gum arabic is abundantly gown wild with some on established farms. The produce is used in the manufacture of many industrial goods like ink, pharmaceuticals, paint, textiles, papers etc. Both descriptive and regression models were used for the analyses. The results revealed that R2 = 0.692, implying that 69.2% of the independent variables used in the study jointly explained the variation in the output. Age, education, operating cost and fixed cost had negative coefficients while family size, purchasing cost, volume of gum arabic sold; labour cost and gum Arabic marketing experience had positive coefficients. These imply that an increase on those variables with negative coefficients will decrease revenue generation in the sales of gum arabic in the area; and an increase in those variables with positive coefficients will lead to increase in the revenue generation in gum arabic marketing in the study area. The gum Arabic marketers were advised to reduce allocation of resources with negative coefficients and increase allocation of the variables with positive coefficients in order to be more efficient in the gum arabic business in the area.

Abstract: In the earlier days of distance learning, it was most common to see distance learning used for rural students who were at a distance from an educational institution. The student might watch a telecourse on a television stations, read texts, mail in assignments and then travel to the local college to take an exam. This model is still in use, but as the technology has become more sophisticated and the cost of distance learning dropped as equipment prices dropped, the use of distance education has increased. High front-end costs prevented an early widespread adoption of electronically mediated learning. Distance learning has been aggressively adopted in many areas because it can meet specific educational needs. As the concept of accountability became accepted and laws required certain courses in high school in order for students to be admitted to state colleges, telecommunications was examined as a way to provide student access to the required courses. Many rural school districts could not afford the special teachers to conduct required courses. Distance education met this need by providing courses in schools where teachers were not available or were too costly to provide for a few students. It also fulfilled a need for teacher training and staff development in locations where experts and resources were difficult to obtain. These systems link learner communities with each other and bring a wide array of experts and information to the classroom.

Abstract: The objective of this paper was to assess broiler responses to reduced protein and energy diets supplemented with Lysine, Methionine and Threonine. A data envelope analysis was used to estimate technical and economic efficiency of diets. The results showed that treatment two (T2) with control energy level, lower crude protein and high Lysine, Methionine and Threonine contents are technically and economically efficient compare to standard feed components in treatment one (T1), and to other treatments (T3 and T4) with variable crude protein and Lysine, Methionine and Threonine and energy contents. Also the results proved that age of 33 days is optimum period for broiler to gain optimum body weight that provide desirable technical and economic efficiency.
