Antidiabetic Effect of Pleurotus ostreatus (Jacq.ex Fr) kumm. Mushroom on Alloxan-induced Diabetic Rats.
Imoh Johnny,Joseph Okon
Indian Journal of Pharmaceutical and Biological Research , 2013,
Abstract: Antidiabetic effects of ethanolic extract of Pleurotus ostreatus (mushroom) on alloxan-induced diabetic ratswas studied. The median lethal dose (LD50) of the extract was determined to be 3,472.14 mgkg-1 and a singledose of 380.0, 760.0 and 1140.0 body weight of the extract were intraperitoneally administered as thetreatment dose and the blood glucose levels (BGL) examined for 7 hours and 15 hours (prolonged) at 2 and 4hours intervals respectively. The extract exhibited significant (p<0.05 and p<0.01) reduction in the bloodglucose levels of the albino rats. The extract compared favourably with the standard reference drug(metformin) which all gave their maximum BGL reduction at 5 hours duration. The confirmation ofantidiabetic potentials of the Pleurotus ostreatus tuber has been justified in this study as claimed bytraditional medicine practitionersin Akwa Ibom State.

Abstract:

P-wave and S-wave velocities were obtained from seismic refraction survey in the foundation layer of Eket, the study area. The Tezcan’s approach discussed extensively in the work was used in conjunction with the existing mathematical relations between elastic parameters and seismic refraction velocities for the study of foundation layers in the study area. Based on the results, the elastic constants, allowable bearing pressure/capacity, ultimate bearing capacity and other parameters in Table 1 were determined. The result shows that allowable bearing pressure increases with increase in shear modulus and shear wave velocity. The empirical relation between allowable bearing capacity and shear modulus shows that the allowable bearing capacity increases with depth. Comparing our findings with some ranges of safe allowable bearing capacities of similar non cohesive/granular soils in literatures, the second layer with allowable bearing capacity range of 72.56 - 206.63 kN·m-2 (average = 154.78 kN·m-2) has been considered to be the safe shallow engineering foundation in the study area. The empirical relations between allowable bearing capacities shear modulus and shear wave velocity, in conjunction with the inferred maps, which serve as our findings, will be used as guide in the location of foundations. The inferred ultimate and allowable capacities correlate maximally for the two shallow foundations penetrated by the seismic waves. This perfect correlation reflects the uniqueness of the method.

Abstract: Background In order to initiate a disease elimination programme for lymphatic filariasis based on mass drug administration, a proper understanding of the geographical distribution and degree of risk is essential. Methods An investigation of lymphatic filariasis due to Wuchereria bancrofti was carried out among 785 people in four communities of Yakurr Local Government Area of Cross River State, Nigeria between March and August, 2009. Finger prick blood smear samples collected from the subjects were examined for W. bancrofti using standard parasitological protocol. The subjects were also screened for clinical manifestations of lymphatic filariasis. Results Of the 785 persons examined, 48 (6.1%) were positive for microfilariae in their thick blood smear. There was a significant difference in the prevalence of lymphatic filariasis among the various age groups (P < 0.01) although peak prevalence occurred between 41 – 60 years. There was no significant difference in prevalence and density with respect to sex (P > 0.05). The overall mean microfilarial density of the infected individuals was 5.6mf/50 μl. There was a significant variation (P < 0.01) in mean microfilarial density within the communities, ranging from 4.7 to 6.4 mf/50 μl. The only clinical sign found in the study area was lymphoedema of the leg recording 2 (0.3%) prevalence. Conclusions The National Lymphatic Filariasis Elimination Programme should intervene by expanding the distribution of albendazole and ivermectin to all endemic areas including Yakurr Local Government Area of Cross River State, Nigeria.

International Journal of Geosciences (IJG) , 2011, DOI: 10.4236/ijg.2011.24042
Abstract: In recent years there has been serious concern on the deteriorating groundwater quality due to the activities of man. Geographic Information System (GIS), a high performance computer based tool is playing a critical role in water resource management and pollution study. In this work, the GIS software was used to analyze the effects of various data layers (topographic slope, groundwater table variation, soil porosity and land use activities) on the distribution of groundwater pollution in the Nigerian city of Uyo. Spatial variability map of different groundwater quality parameters were generated using interpolation operation in the software. A good correlation exists between some of the pollution indicators (total dissolved solids, TDS and conductiveity, CN, 0.8; chloride and TDS, 0.17 as well as TDS and sulphate, 0.23). The results of spatial variability maps of different groundwater quality parameters indicate an increase in the percentages of pollution levels during the last five years. Cross operation was also used to explain the effects of various data layers viz. topographic slope, groundwater slope, depth to groundwater layer and land use activities on the distribution of groundwater pollution.
Phenotypic Correlations and Body Weights Prediction Using Morphometric Traits of Snails in Calabar, Nigeria
B Okon, LA Ibom
Ethiopian Journal of Environmental Studies and Management , 2011,
Abstract: Data on hatchling body weights and morphometric traits (hatchling body shell length and hatchling body shell width) pertaining to two breeds of snails (A. marginata and A. achatina) from hatch to fourth (4th) week of age were analyzed. This was used to obtain correlation coefficient of morphometric traits and to generate prediction equations for live body weight of the animals. Strong, positive and significant correlations between hatchling body weight and body shell width (r=0.82) and between hatchling body weight and body shell length (r=0.80) for A. marginata as well as between hatchling body weight and body shell length (r=0.81) and between hatchling body weight and body shell width (r=0.86) for A. achatina were obtained. Low coefficients of determination (R2) were obtained with the range from 4.73% to 41.30% and from 2.12% to 50.20% for A. marginata and A. achatina respectively. Morphometric traits (Hatchling body shell length and body shell width) best predicted hatchling body weights of A. achatina and not of A. marginata snails. Strong, positive and significant correlations imply that selection for these morphometric traits will lead to improvement of hatchling body weights.

OE Johnson, RD Okon
African Journal of Reproductive Health , 2012,
Abstract: This study was carried out to determine the awareness and practice of FGC in a rural community in southern Nigeria. A cross sectional study was carried out among Ayadehe women in Itu, LGA Akwa Ibom State, Nigeria using a semi-structured interviewer administered questionnaire. Information obtained was analysed using SPSS version 17. A total of 218 respondents participated in the study. Majority, 215 (98.6%) were aware of the practice of FGC. Type 2 FGC was the commonest type reported by 71.2% of respondents. Prevalence of FGC was 92.7%. A total of 69.8% were circumcised at 6-12 years. Health complications experienced included excruciating pains, (36.6%), severe bleeding, (15.8%), and painful urination, (26.7%). Up to 53.5% were circumcised by traditional birth attendants. The belief that FGM should be discontinued increased with educational level. The practice of FGC was high in this community. Increased female education, community involvement and legislation are needed to reduce this practice (Afr J Reprod Health 2012; 16[4]: 132-139).
Resource Use Efficiency among Urban Vegetable Farmers in Akwa Ibom State, Nigeria
Okon, UE.,Enete, AA.
Tropicultura , 2009,
Abstract: The study estimated the efficiency of resource use among urban vegetable (Talinium triangulare) farmers in Akwa Ibom State using a sample of 60 respondents that were randomly selected; 20 from three urban centers in the state. Interview schedules and structured questionnaires were administered to elicit information from the respondents. Data were analyzed using descriptive statistics, multiple regression and gross margin. The results showed that, most (85%) farmers were within the economically active age bracket (21- 50 years). All farmers were female with a mean farming experience of 8.5 years. The average farm size was 0.065 ha, and waterleaf was planted as a sole crop to obtain high output. The multiple regression analysis showed that the farmer's farm size, educational level, household size, farming experience and quantity of manure and labour applied, positively and significantly influenced output of waterleaf in the study area. The efficiency ratio of land (2.8), manure (42.11) and labour (0.91), showed that waterleaf farmers were inefficient in the use of these resources. Land and manure were underutilized, while labour was over utilized. Gross margin analysis showed that farmers made profit (gross margin= N287, 252.52 per hectare). Lack of access to credit facilities was the farmers' major constraints.
Distortion of Facts in Western Ethnographic Study of African Religion, Culture and Society
Etim E. Okon
International Journal of Asian Social Science , 2013,
Abstract: This paper will identify some of the fundamental short comings in African ethnographic studies undertaken by Europeans in the nineteenth century. Existing works on Africa reveal a lacuna that is depressing to scholarship. The gap has to do with the failure of some Western researchers to approach African study as a unique venture. Admittedly, there are elements of interdependence and continuity in scholarship, but that does not equate belief systems into a unified whole. European ethnographers came to Africa with the ethnocentric mind-set that did not allow them to study the people's culture and religion objectively. The greatest negative impact of the lopsided ethnographic study of African society was in the misinterpretation of the traditional religion. The primary objective of this paper is to correct the hermeneutical error which has hindered progress in the understanding of the African world-view.
Islamic Jurisprudence and the Primacy of Shariah
Etim E. Okon
International Journal of Asian Social Science , 2013,
Abstract: The purpose of shariah like any other legal system is the maintenance of law and order. Society cannot achieve peace and prosperity without some form of social control. Outlawry can only lead to social disequilibrium. The focus of this paper is not the legal or juridical functions of the shariah, but the social and political dimensions of Islamic jurisprudence. Since the purpose for being of an Islamic state is the full implementation of the shariah, the aim of this study is to evaluate the nature and content of Islamic jurisprudence. The study will assess the compatibility or otherwise of Islamic jurisprudence with contemporary developments in international human rights and humanitarian law and the suitability or otherwise of implementing shariah law in a democratic and liberal society.
