Abstract: The study examines parents/guardian` attitude towards reading habit of their children in Osogbo metropolis. Twelve wards were selected from two local government areas in the metropolis by using multistage sampling technique and ten household (parents) were chosen using systematic random sampling. In all 120 parents/guardians were sampled and interviewed. The data were analyzed using simple descriptive statistics such as frequency count, percentages, bar and pie chart. The findings revealed that most of the parent had moderate number of household members but they were low income earners. Concerning the children reading habits, most parents said that their wards only read during examination periods, only few affirmed that their wards read regularly at scheduled time. Reading facilities were not adequately provided at home and children spent most of their free time watching television, playing with friends and doing household chores. It was therefore, recommended that parents should spend more time with their children, regulate and monitor their activities at home and provide conducive environment for them to read.

Pakistan Journal of Nutrition , 2004,
Abstract: The fresh, ripe fruits of Solanum melongena and Solanum gilo were investigated for their possible hypolidemic potentials in hypercholesterolemia induced in New Zealand white rabbits by feeding the animals with normal diet supplemented with 1% cholesterol and groundnut oil for 3 weeks. Hypercholesterolemic rabbits were thereafter treated with normal diet supplemented with 10% of each fruit for 6 weeks. Rabbits fed with normal diet and hypercholesterolemic diets through out the experiment were used as negative and positive controls respectively. There was a significant increase in the weight of hypercholesterolemic rabbits, both test (Groups D & E) and control (Groups B and C) (P<0.01) compared with normal control (Group A). It was observed that the hypercholesterolemic rabbits treated with normal diet elicited a significant reduction in fasting serum cholesterol (11.52%), triglyceride (16.5%) and LDL cholesterol (41.13%) but a significant increase in HDL cholesterol (16.48%) and also in the HDL/LDL ratio (1.10), four weeks after replacement of high cholesterol diet with normal diet. This positive response was however more pronounced in fruits treated rabbits. Solanum melongena and Solanum gilo significantly reduced serum total cholesterol by 65.40 and 52.69% respectively, triglyceride by 47.7 and 27%, LDL cholesterol by 85 and 83% respectively. They also increased significantly serum HDL by 24.7 and 25% respectively leading to increased HDL/LDL cholesterol ratio (3.37 and 3.25 respectively). This trend was also similar with liver lipid levels. Histopathological examination of the liver and aorta paraffin section stained with Haematoxylin & Eosine showed fewer lesions in the hypercholesterolemic rabbits treated with Solanum fruits compared with control hypercholesterolemic rabbits. These observations demonstrated that Solanum melongena and Solanum gilo have strong hypolipedemic effect which combined with improved HDL/LDL ratio is an indication of the possible use of this fruit in the treatment of diseases associated with hyperlipidemia such as ishcaemic heart diseases and arteriosclerosis.

American Journal of Food Technology , 2012,
Abstract: Most food handlers in fast food centers have no knowledge of food safety practices and of prevention of food-borne diseases which has resulted in the transmission of food-borne pathogens to the people consuming such food. Therefore, this study was aimed at evaluating the level of bacterial contamination in some fast food in Ogbomoso, Nigeria and to determine the antibiotic susceptibility and physiological profile of the bacterial contaminants. Bacterial pathogens were isolated from fast food vended in Ogbomoso, Oyo state, Nigeria. The isolates were characterized and identified as Enterobacter aerogenes, Aeromonas hydrophila, Pseudomonas putida, Escherichia coli, Proteus vulgaris, Micrococcus luteus, Bacillus cereus, Pseudomonas chlororaphis and Bacillus subtilis. The total bacteria colony count ranged from 2.4x104-4.2x106. The antibiotic susceptibility profile of the isolates was determined and 75% sensitivity to the clinically relevant antibiotic disc was noted while 25% resistance was found. The effect of physiological parameters including temperature, pH and sodium chloride concentration on the growth rate of isolates was evaluated. As temperature of incubation increased from 50-80°C, the rate of growth of all the isolate decreased and as the pH of the growth medium increased from 3-9, the rate of growth of all the isolates also increased. As the concentration of sodium chloride increased from 2-5%, the rate of growth of isolates also reduced. The results of this study showed that most of the fast food samples examined did not meet bacteriological quality standards. Hence, it is recommended that a regular monitoring of fast food should be carried out by putting in place appropriate agency.

Abstract: Specimens of High Vaginal Swabs (HVS) of 135 pregnant women were examined to determine the cause of vaginitis in pregnant women in lseyin, Oyo State, Nigeria between August and October 1999. Study subjects were selected from patient attending selected antenatal clinics in public, private and mission hospitals/clinics in lseyin. Samples were collected from subject in lithotomy position using sterile cuscos bivalve speculum. Samples were analysed by using standard technique as described. A structured questionnaire was also administered in order to obtain vital epidemiological information necessary for the study as described. The data analysis was done using chi square test. Results shows that 45 (33.3%) were positive for Candida spp, 15 (11.1%) for Gardnerella vaginalis and 5 (3.7%) for Trichomonas vaginalis. Sexual activities of individual have no significant effect on prevalence of vaginitis while symptomatology was a major indicator of infection. The effect of educational attainment and religion on infection rate was discussed. Infection decreased with age of patients while infection distribution by age of pregnancy gave a confusing pattern and the factors responsible for this were discussed. Since vaginitis could be asymptomatic most time, the screening of all pregnant women with risk factors for preterm labour and premature rupture of membranes must be undertaken. Prompt treatment of cases is also recommended. Key Words: Pregnant women, vaginitis, aetiologic agents, prevalence, Iseyin. (Af J Clinical & Exp Microbiology: 2003 4(2): 116-126)

Abstract: Diabetic patients comprise a large proportion of our outpatient population and deserve special attention. To determine the prevalence, the clinical characteristics, risk factors, causative organisms and antimicrobial susceptibility of Urinary Tract Infection (UTI) in diabetic patients. Mid-stream urine samples were obtained from a total of 320 patients attending medical outpatient clinic, University College Hospital, Ibadan and apparently healthy volunteers from February to July 2006. Medical records were also reviewed and the patients were divided into two groups according to the presence or absence of diabetes, Patients that were confirmed to be diabetic were included in the study. Out of 320 midstream urine samples examined, 174(54.3%) were diabetic, out of which 37(21%) had significant bacteruria, these include 23(61.9%) females and 14(38.1%) males while in 146 control healthy volunteers only 7(5%) had significant bacteruria, which accounted for 84(58%) of male and 62(42%) of female within the age range of 20-65. Escherichia coli was the predominant bacterial isolate as a causative agent of urinary tract infection in both diabetics and healthy volunteers The antibiotic sensitivity pattern showed that most islolates were sensitive to ofloxaxin, Gentamycin, Nitrofurantoin, Nalixidic acid, Cotrimaxole and Rocephine while they are resistant to tetracyclines, ampicillins, cefuroxime and ceftazidine. The complications of diabetes are of great importance both financially and in terms of mortality and morbidity, because of frequency and severity of UTI in these groups of patients it is recommended that periodic screening of diabetics patients be undertaken to permit early detection and treatment of assymptomatic bacteruria.
A resposta metabólica ao trauma cranioencefálico é autolimitada? Análise das proteínas de fase aguda e glicemia
Arquivos de Neuro-Psiquiatria , 1998, DOI: 10.1590/S0004-282X1998000500013
Abstract: there are many reports supporting a self-limitation mechanism involved with hypermetabolic response after severe cranial injury. it was proposed a study with severe head injury patients, in three stages of the evolution. the first 7 days after admission (moment 1- m1), the second three days latter (m2) and the last 7 days after the first (m3). among male patients with severe head injury, attended between january 1992 and december 1993 in university hospital of botucatu, unesp, were selected 28 male patients, with glasgow severity scale between 4 and 6, with po2< 70 mm hg, weighting 60 kg or more. among these patients, 6 finished the study, including analysis of the excretion of n, acute phase proteins, glycemia, triglycerides and amine nitrogen. during the study there were no changes in nitrogen balance and there was a decrease in protein c-reative. glycemia tends to fall within two weeks after injury. the authors make some considerations about possible mechanisms involved in brain modulation associated with the period of dependence of hypermetabolism and hypercatabolism after closed brain injury. there are some evidences that the brain responds to head trauma with a gobal non specific way, which tends to be reorganized beyond the first two weeks after lesion. the study does not show any influence of the type and severity of head trauma.

Pakistan Journal of Nutrition , 2010,
Abstract: Kunun-zaki was prepared using millet as the base and supplemented with beniseed at varied level (0-50%). The effect of added beniseed on the physio-chemical (moisture, ash, protein, fat and carbohydrate), sensory (colour, taste, odour/aroma, mouth feel and general acceptability) and microbial qualities were evaluated. The added beniseed decreased the moisture, ash and carbohydrate composition from 86.23-85.03, 0.33-0.22 and 10.21-7.23%, respectively with increasing concentration (0-50%), while fat and protein increased from 1.03-2.03% and 2.21-5.44% respectively with increasing concentration (0-50%). The added beniseed paste had a high positive correlation coefficient (r = 0.75-0.95) with the increase in the protein, fat and energy content. There were significant differences in the assessed sensory qualities (colour, odour, taste, texture) at 20% and above added beniseed paste which corresponds with 3.32%, 1.26% and 64.06 kcal of protein, fats and energy content respectively. At this acceptable level the protein content of the products has been improved by 50% if digested and absorbed.

Arquivos de Neuro-Psiquiatria , 1998,
Abstract: Nos últimos anos tem havido referências à limita o da resposta metabólica nas duas primeiras semanas após trauma cranioencefálico (TCE). Foi feita proposta de estudo a partir de experimento clínico em pacientes com trauma encefálico grave, que foram avaliados por volta de 7 dias após a les o (M1). A segunda avalia o ocorreu 4 dias após (M2), e a terceira 3 a 4 dias após (M3). Em um período de 2 anos, foram selecionados 28 pacientes do sexo masculino, com trauma encefálico grave, escala de gravidade de Glasgow entre 4 e 6. Dentre os 28 pacientes, 6 completaram o estudo proposto. Os pacientes foram acompanhados clinicamente durante toda a fase do experimento. Em cada um dos momentos de análise, foram feitas análises da excre o nitrogenada e proteínas de fase aguda. Da mesma forma foram feitas determina es da glicemia plasmática, N-amínico e triglicerídeos. Os resultados do estudo demonstraram n o haver modifica es no balan o nitrogenado, normaliza o da proteína-C-reativa e redu o relativa da glicemia ao final do experimento. Os autores tecem considera es sobre os possíveis mecanismos envolvidos na modula o da resposta metabólica e concluem que o hipermetabolismo, a basear-se na análise da glicemia e das proteínas de fase aguda, n o persiste além do 13° dia do período de recupera o pós-trauma. S o feitas sugest es de estudos futuros que possam elucidar os mecanismos envolvidos na normaliza o do hipercatabolismo e hipermetabolismo observados nas duas primeiras semanas após TCE.

Abstract: Agricultural pests are the insects that feed on crops and damaged them. Most current agricultural pest control methods focused on chemical insecticides. Research works have shown that these chemicals have many disastrous consequences. However, effective control of these pests can be obtained through the use of living organisms to reduce the density of pest below economic damaging level and this is refers to as biological pest control. If a mathematical model for the biological system is provided, then the effects of such pests can be controlled by the methods of optimal control theory. In this study, the biological control of agricultural pest system via optimal control theory approach was qualitatively studied. In an attempt to minimize the pest population below injury level and stabilize the natural enemies' population. The system was analysed, equilibrium point for the system was determined, stability and economic loss free equilibrium was equally established. Numerical values were employed to check for the validity of the method and the result was found to be effective.
