ABSTRACT Adoption of a technology varies from place to place. According to the Rogers Diffusion Theory, most technologies are adopted by farmers if they are perceived to have returns. It is from this view point that this research assessed the role of socioeconomic and environmental factors in the diffusion of the zero grazing (ZG) technology in Samia Sub-County, Kenya. A survey, using a questionnaire and observations was conducted in Lower and Upper Samia. The study employed strata sampling,...
SUMMARY Amoebiasis exemplifies a disease of protean manifestations which presents many perplexing problems. In this thesis an attempt is made to define a number of the wide variations which have been observed in the pathological manifestations of the disease. The work consists of both retrospective and prospective Studies. The retrospective study involved a review of the 7922 protocols of the autopsies at the University College Hospital, Ibadan, during the ten year period 1958 to 1967. 135 ca...
ABSTRACT An assessment of the efficiency of heavy metals removal by a constructed wetland system at Egerton University, Kenya, was conducted between August 2013 and January 2014. The aim of the study was to evaluate the physico-chemical characteristics of wastewater and investigate heavy metals retention in the wetland. Water samples were collected monthly in plastic bottles at the inlet, along the wetland, and at the outlet; sediment samples were collected from the gravel bed and the three ...
Abstract The objective of this study was to determine the knowledge and perception of Nigerian Obstetricians and Gynaecologists towards human papilloma virus vaccine use in Nigeria. A cross sectional study was conducted amongst participants that attended the 42nd Society of Gynaecology and Obstetrics of Nigeria. The findings revealed that 44.5% knew the correct HPV vaccine schedule. Regarding implementation in Nigeria, 87.4% suggested its incorporation into the national immunization progra...
ABSTRACT With an ever-increasing global need for sustainable animal protein, agriculturists are turning to aquaculture for an alternative source of protein and revenue. Aquaculture is widely considered as an important component for enhancing food security, income and nutrition. Tilapias are considered as the best species for culture globally and in Kenya, Oreochromis niloticus has shown significant success. However, little is known about the aquaculture potential of Oreochromis jipe. This st...
Abstract The Prevention of Mother to Child Transmission (PMTCT) prome in the University CoIlege Hospital (UCH), Ibadan has been in existence for more than five years and has scaled up to other sites. The study evaluated the service uptake and performance of the programme using national key indicators. Antenatal and delivery records of women enrolled between July 2002 and June 2007 were reviewed. A total of 51952 women attended first antenatal visits and received HIV pre-test counseling. Of th...
ABSTRACT Over the recent years, sexual activities among students in Secondary Schools in Nigeria, particularly those in urban areas, are thought to be high and increasing# The resultant unwanted pregnancies and illegal abortions among these young unmarried population are creating social and health problems (Nichols, et al, 1986). According to previous research findings, included in the causative factors responsible for this unfortunate situation, cure the problems of poor knowledge of Family ...
ABSTRACT In recent years, mortality due to leptospirosis in dogs has been of major concern in Southwestern Nigeria, but the prevalent serovars, pathology and pathogenesis have not been fully documented. The purpose of this study was to investigate the disease in the dog and reservoir hosts (cattle and wild rats), and its pathogenesis and pathology in a guinea pig model. Between 2003 and 2010, 44 fresh and 60 formalin-fixed kidneys of tentatively diagnosed cases of canine leptospirosis o...
ABSTRACT The seed oil of Leuconia leucocephala was investigated for its antimicrobial activity and the pharmaceutical properties of its lotion formulation determined. The oil was extracted from the pulverised dried seeds of the Leuconia leucocephala plant by cold maceration in n-hexane. The oil was tested against four bacteria (Staphylococcus aureus, Esherichia coli, Bacillus subtilis and Pseudomonas aeruginosa) and four fungi (Aspergilus niger, Rhizopus stolon, Penicillum notatum and Cand...
ABSTRACT The purpose of this study was to evaluate the bioadhesive properties of native and modified cocoyam (Xanthosoma sagittifolium) starches. The methods of modification were by pregelatinisation and acetylation. The starch particles were evaluated for characteristics like particle size, swelling ability, viscosity, and mucoadhesion. The mucoadhesive evaluation of the starches were done using the rotating cylinder methods in 0.1M HCl and Phosphate buffer (pH 6.8) to simulate the st...
Abstract Plasma HIV-1 RNA concentration, or viral load, is an indication of the magnitude of virus replication and largely correlates with disease progression in an infected person. It is a very useful guide for initiation of therapy and monitoring of response to antiretroviral drugs. Although the majority of patients who are not on antiretroviral therapy (ART) have a high viral load, a small proportion of ART naive patients are known to maintain low levels or even undetectable viral load lev...
Abstract Bilayer tablets of aceclofenac sodium were developed using carboxymethylated whit yam (Dioscorea rotundata) starch (CWY) for a fast release layer (2.5, 5.0, and 7.5% w/w), and acid-hydrolyzed bitter yam (Dioscorea dumetorum) starch (ABY) for a sustaining layer (27% w/w). Sodium starch glycolate (SSG) and hydroxypropyl methyl cellulose HPMC)were used as standards.The starches were characterized using Fourier Transform Infrared spectroscopy (FT-IR), particle size, swelling power, densi...
Hypertension is a multifactorial disorder because of the interaction of risk genes and environmental factors. Angiotensin II is a well-known vasoconstrictor that exerts most of its influence through the angiotensin Il type 1 receptor. The A1166C polymorphism is a single base substitution of adenine for cytosine at position 1i66 in the 3 untranslated region of the gene. There are conflicting reports on the association of the Al166C polymorphism with cardiovascular diseases such as prevalent hy...
ABSTRACT Water pans are excavated earth with embankments used as boundaries that are used to harvest surface runoff. Water pans are the main sources of water for domestic purposes in arid and semi-arid lands, however, lack of protection and water treatment of this water sources exposes the dependent communities to human health problems. This study sought to assess the microbiological water quality of water pans in relation to prevalent water-related diseases in the study area. This was achie...
ABSTRACT Adolescent pregnancy is an important public health problem on the increase in Nigeria. Few studies have investigated the circumstances and factors associated with parental decisions taken following an adolescent pregnancy, in spite of the implications of these on the adolescent. This study was designed to assess factors influencing parents‟/guardians‟ decisions on adolescent pregnancy. A mixed method study involving the use of Key Informant Interviews (KII) and semi-structure...
