Effects of Aqueous and Methanol Extracts of Zingiber officinale on the Haematological Profile in Schistosoma haematobium-Infected Mice
Y. Labe,H.I. Inabo
International Journal of Animal and Veterinary Advances , 2012,
Abstract: The aim of the study was to evaluate the immunomodulating effects of aqueous and methanol extracts of Zingiber officinale on the haematological profile in Schistosoma haematobium - infected mice.The weight and haematological profiles of Schistosoma haematobium - infected mice were assessed to evaluate the immunomodulating effects of aqueous and methanolic extracts of Zingiber officinale at post-infection and post-treatment. There was a non-significant decrease (p>0.05) in the weight of mice in all the groups. However, there was a significant increase (p<0.05) in the total white blood cell counts, neutrophils and lymphocytes for group I (S. haematobium - infected mice treated with 9.5 mg/kg aqueous extract of Zingiber officinale). In group II - (S. haematobium - infected mice treated with 87 mg/kg methanolic extract of Zingiber officinale), there was significant increase (p<0.05) in the haemoglobin level and white blood cells. Methanolic extract of Zingiber officinale has better anti-anaemic effect than the aqueous extract of Zingiber officinale. There was no relationship between the level of eosinophils and the treated mice. No significant change in the haematological indices was observed in the group which was administered the standard drug- Praziquantel (PZQ). The immunomodualting effects of aqueous and methanol extracts of Zingiber officinale when compared to PZQ are promising in immunosuppressed Schistosoma haematobium- infected mice. Fractionation of the crude extract of Zingiber officinale may further identify the bioactive components required for treatment of urinary schistosomiasis.

D Abba, H.I Inabo, S.E Yakubu, OS Olonitola
Science World Journal , 2009,
Abstract: The aim of the study was to investigate the phytochemical components and the antibacterial activities of some powdered herbal medicinal preparations sourced from identified herbal shops and retail outlets in different parts of Kaduna metropolis. Extracts obtained from the herbal preparations were screened for the presence of secondary metabolites using established procedures. Also, antibacterial activities of the extracts were evaluated. Carbohydrates and tannins were identified in 105 (70%) and 101 (67.3%) of the samples respectively. Alkaloids were found in 97 (64.7%); saponins were detected in 91 (60.7%), while anthraquinones, flavonoids and cardiac glycosides were identified in 82 (54.7%), 80 (53.3%) and 60 (40%) of the herbal preparations respectively. All the methanolic extracts had inhibitory activities on the test bacterial isolates at various minimum inhibitory concentrations: 81 (54%) had inhibitory effects on Staphylococcus aureus, 74 (49.3%) on Escherichia coli, 74 (49.3%) on Salmonella typhi and 63 (42%) on Shigella spp. The uses of these products in herbal medicine are justified. However, further works are needed to identify the chemical nature of the active substances as well as their modes of actions on the bacterial cells and their roles in disease curing.
Effects of River Erosion on Houses: A Case Study of Asa River Catchment in Ilorin, Kwara State, Nigeria
H.I. Jimoh
The Social Sciences , 2013,
Abstract: This research is an assessment of the effects of river bank erosion on houses in Ilorin, Kwara State, Nigeria. Data were generated through direct field exercises. Such data were on the competence and capability of a river, physical characteristics of soil in the local environment, distances between the houses and river banks and the distances between the houses. These data were subjected to statistical methods of analyses. The following results were therefore, observed: the bulk of the soil in the local environment is loose in disposition and thus susceptible to the forces of erosion, the force of river`s competence and capability considerably explains the qualities of the river`s evorsion process, houses are randomly distributed but with most of them appearing linearly along the water course, distances between houses and rivers banks are short and thus most of the houses are often embarrassed by floods and people often lost both their lives and properties when the river is in floods. This study further suggests environmental education on flood management and the evaluation of a policy of resettlement scheme for flood prone areas.

Heavy metals determination and assessment in a petroleum impacted River in the Niger Delta Region of Nigeria
H.I Owamah
Albanian Journal of Agricultural Sciences , 2013,
Abstract: The concentrations of heavy metals in (mg/g) of Pb, Ni, Cu, Cr, Fe, Co, Cd, and Hg in the water and sediments of river Ijana Warri, were determined in order to assess the impact of petroleum-processing activities on the river and the surrounding environment. The data showed that the levels of these metals ranged between 0.15-1.18 mg/g and 0.10-0.48 mg/g in sediment and water respectively. The heavy metals concentrations reported for the water have an abundance trend in the order of Pb>Fe>Ni>Cr>Cu>Co> Cd >Hg, while those of the sediments is in the order of Pb > Fe > Cr > Ni > Cu > Cd > Hg > Co. The control analysis was carried out in a non- oil polluted river (Ikpoba River) and the values served as base line values for the study.
Problems of Suspended Sediment Loads in Asa River Catchment, Ilorin, Nigeria
H.I. Jimoh,Ajao Lukman Ishola
Pakistan Journal of Social Sciences , 2012,
Abstract: This research is an assessment of the rate of the presence of sediment loads in Asa river catchment. This is with a view to explaining the inherent problems in such sediment compositions in the water body. To achieve this, data sets were primarily sourced, analysed and the following constitutes as the Observations: The properties of basin that facilitates sediment transportation from source to the destination include depth of water, bank full, average velocity, discharge, river competence and capability. Similarly, these parameters along with circularity ratio, bifurcation ratio, relief, basin length, total mean length, basin size, drainage density among others explains the ability of streams to transport sediment materials in suspension. Thus, problems often created by sediment deposits range from river siltation and eventually drying up. Averting this situation will involve water dredging, straightening of water channels to general environmental education with special reference to watershed management.
An Empirical Analysis of Causality Between Financial Development Economic Growth: Further Evidence from Sub-Saharan Africa
T. Egbetunde,H.I. Mobolaji
Journal of Economics Theory , 2012, DOI: 10.3923/jeth.2010.50.58
Abstract: The study examines the long run and causal relationship between financial development and economic growth for ten countries in sub-Saharan Africa. Using the Vector Error Correction Model (VECM), the study finds that financial development is co-integrated with economic growth in all selected ten countries in Sub-Saharan Africa. Moreover, this test supports the estimated coefficient of the error correction terms found statistically significant with a negative sign which confirmed that there was not any problem in long run equilibrium between financial development and economic growth in the countries. Granger causality based on multivariate VECM further shows that financial development Granger causes economic growth in Burundi, Cameroon, Mali and Nigeria while economic growth Granger causes financial development in Benin, Burkina Faso, Madagascar and Malawi. Within the same framework, the evidence of bidirectional causality shows between financial development and economic growth in Cote d'Ivoire and Ghana. Based on these results, the study argues that financial development could help promote economic growth in four countries while economic growth could help promote financial development in four countries and financial development and economic growth promote one another in 2 countries. However, to achieve these goals, financial markets need to be further developed through appropriate regulatory and macroeconomic policies which in turn accelerate economic growth in Sub-Saharan Africa.
Erosion and Gullying along Some Road Networks in a Third World City
H.I. Jimoh,P. Gbeworo
Pakistan Journal of Social Sciences , 2012,
Abstract: This research has assessed the roles of erosion on road networks. Data were primarily sourced and analysed through the applications of descriptive and cross tabulations as basic methods of data analyses. Consequently, the following observations were made as follows: An average of 22 erosion sites on each road transect has been observed and each erosion site has a mean depth of about 22.3 cm. The consequences of erosion ravages on the affected parts of roads ranges from imposition of stress on road users, increased in accident rates, increase in motor servicing bills to rendering of roads impossable. Erosion on road networks can possibly be check by healing the affected road surfaces through sand fills. Generally, erosion along the high ways greatly disturbs road geometry, the consequences of which are several and hazardous on both man and the general scenic appearance of the environment. Thus, abating the problems of erosion at incipient stage before it gets into gully stage and emphasizing environmental education in schools curriculum are emphasized in this research.

The Fiscal-Monetary Policy and Economic Growth in Nigeria: Further Empirical Evidence
H.A. Adefeso,H.I. Mobolaji
Pakistan Journal of Social Sciences , 2012, DOI: 10.3923/pjssci.2010.137.142
Abstract: The objective of this study was to re-estimate and re-examine the relative effectiveness of fiscal and monetary policy on economic growth in Nigeria using annual data from 1970-2007. The Error Correction Mechanism and Cointegration technique were employed to analyze the data and draw policy inferences. The findings were consistent with previous empirical findings. The empirical result showed that the effect of monetary policy is much more stronger than fiscal policy and the exclusion of the degree of openness did not weak this conclusion. The implication of this for the policy maker is that there should be more emphasis and reliance on monetary policy for the purpose economic stabilization in Nigeria.
