ABSTRACT

Mostly grown as a food source in Africa, cassava is the third largest source of carbohydrates in the world and it is considered as a staple food in most African countries. Despite its enormous potentials, African cassava mosaic disease (ACMD) has been causing yield losses in this plant mostly for particular varieties under specific conditions. On the basis of this, it became necessary to probe more into the effects of ACMD on growth and biocentrations of phytochemical and leaf chlorophyll pigments of M. esculenta. Test plants were sourced and propagated in a completely randomized design method. Three months post cultivation the diseased and healthy plants were harvested and studied for growth performance using graphical method, weighing and linear measurements. The phytochemicals of both infected and uninfected plants were determined using standard methods as proposed by Association of Official Analytical Chemist whereas the chlorophyll pigments were evaluated by spectrophotometer. The results revealed that ACMD caused significant reductions (P<0.05) in all the growth parameters of M. esculenta when compared with healthy sample. The mean shoot height of 12.71 ± 0.31 cm was obtained in the diseased sample whereas the healthy sample had 28.0 ± 2.11 cm respectively. There were significant (P<0.05) increases and decreases in the amounts of phytochemicals following ACMD infection of M. esculenta. All the chlorophyll pigments measured were significantly reduced in ACMD infected plants. There is need to control the spread of ACMD through the use of resistant varieties and adoption of effective agronomic practice in all cassava growing regions.

ABSTRACT

Castor bean (R. communis) and Physic nut (J. curcas) are multipurpose shrub with a variety of applications and enormous economic potential for seeds oils, which can be converted into biodiesel (an alternative to petrol diesel),  biolubricant, transformer oil etc. . This study investigates the effect of extraction methods on the properties of Castor and physic nut oils obtained from two non-edible indigenous plants in Idah, Kogi state, Nigeria. The oils of Castor bean and Physic nut were extracted by two different methods; solvent using soxhlet extractor and   mechanical press. The physico- chemical properties of the oils such as moisture content (%), specific gravity, acid value (mg KOH/ g), refractive index, saponification value (mg KOH/ g), peroxide value (meq/kg) and iodine value (g/100g) were also determined within a period of six months. For castor oil the values ranged from 11.77-13.33; Nil – 2.86 (%); 0.8852 – 0.8900; 0.9507-0.9572; 5.07-8.67; 0.87-2.10 (mg KOH/ g); 1.4680-1.4586; 1.4770-1.4694; 178.03-154.90; 173.91-146.68 (mg KOH/ g); 3.57-7.77; 1.18-2.80 (meq/kg); 82.83-90.35; 81.24-89.64 (g/100 g) for solvent and mechanical press extraction methods respectively. For J. curcas oil, values range from 12.96-14.00; 2.00-3.77(%); 0.8778-0.8850; 0.9177-0.9246; 10.37-18.52; 11.50- 19.66 (mg KOH/ g); 1.4646-1.4541; 1.4688-1.4587; 208.55-176.45; 203.06-170.68 (mg KOH/ g); 6.31-9.65; 6.73-10.32 (meq/kg); 95.11-100.92; 93.35- 98.51 (g/100g) for solvent  and mechanical press extraction methods respectively. The values obtained in this study are within the standard range, whereas some have about 1% variation. The oils of castor bean and physic nut are non edible because they contain toxic substances; ricin, ricinine and phorbol esters respectively; but can be used for energy application, soap production, shampoo production, lubricant e.t.c.

ABSTRACT

Ortion in the columnar epithelia cells and in connective tissue of lamina propria. These findings were not observed in the control groups when both groups were compared. Based on the above findings the study therefore concludes that atrazine herbicide has deleterious effect on the organs of the digestive system. Keywords: Atrazine, Hepatocyte, Fumigation, Herbicide, Stomach and Intestine. This study was carried out to determine the effect of atrazine (triazine) herbicide on the structural features of some digestive organs. Twelve (12) Albino Wistar rats weighing 96.1kg – 99.9kg were divided into 4 groups. Two groups made up of four rats in each group were the experimental group while the remaining two groups made up of the same number of rats were for the control. The males were separated from the females. Experimental groups feed pellets were treated with 3 mls. of the herbicide. The rats were fed with the treated feeds for the period of 28 and 42 days after which the selected organs (liver, stomach and large intestine) were harvested. The control groups were also fed for the same period of time but the feeds were not treated with atrazine herbicide. The organs mentioned above were also harvested from the control groups. Histological analysis was carried out on the organs and the results showed irregularity of hepatic columns in the liver. Some hepatocytes have clear vacuolated cytoplasm and densely stained nuclei. Congestion of central vein which was as a result of uneasy flow of blood due to improper oxygenation and dilation of the blood sinusoids with the disappearance of the hepatocytic vacuolation which resulted to increased number of mitotic figures and prominent nuclei on rat liver exposed to atrazine for 28 and 42 days were also observed. There were damages in the mucosal layer and degenerative changes in columnar epithelial cells in the stomach of the experimental animals.  Fatty deposition in the basal region, top plate thinning on stomach exposed to the herbicides for 28 and 42 days were also noticed. The large intestine of the rats fed for 28 days with treated feeds showed detachment of epithelia layer from lamina propria while that of the rats fed for 42 days showed dist

ABSTRACT

This study investigated the leucocyte counts of children infected with HIV in Aba Metropolis.  The study population was 242 subjects recruited from Abia State University Teaching Hospital Aba, Abia State.  They were made up of 121 children infected with HIV and 121 children not infected with HIV.  They were male and female children who visited the hospital for HIV screening test.  Those with HIV were the children that tested positive while those without HIV were the children that tested negative.  Their records were retrieved from the record section of the hospital.  Routine laboratory methods for the determination of white blood cell count, Differential count and CD4+ Cell Counts were used.  The result showed that the mean values for the parameters studied in both male and female children without HIV infection were higher than those of the children with HIV in all the age ranges, except the total white blood cell count that reverse were the case. For the CD4+ cell count, the mean values for the age range 5-9 years was the highest, followed by age range 1-4 years and lastly 10-14 years in both the male and female children. The study therefore concludes that the leucocytes counts in children without HIV infection were higher than those of the children with the infection and that this might be due to the fact that the virus attacks the cells thereby decreasing their number.

Keywords: Leucocytes, children, infection, human immunodeficiency, and Lymphocyte.

ABSTRACT

Drug addiction is one of the worst global pestilence that affects virtually all sectors of society in the world. The widespread of this menace triggered the creation of agencies to fight drug peddlers and treatment centers for rehabilitation of the infected ones. However, these treatment centers were created focusing primarily on detention approach of treatment instead of medication and mind abstinence, neglecting the patients’ mental, psychological, social, and spiritual needs, which are the important ingredients that contribute towards achieving effective treatment. This study aimed to integrate therapeutic techniques in drug rehabilitation centre design For the purpose of this study, visual survey, observation checklists and structured interview were used as instruments of data collection. The design is intended to provide a model for a responsive drug rehabilitation center that facilitates drug addicts’ recovery.  It was recommended that the government should provide more treatment facilities that will help in drug abuse and also emphasize on making the centers more supportive and therapeutic and the National Drug Law Enforcement Agency(NDLEA) should collaborate with other stakeholders such as religious institutions and nongovernmental organizations to  counsel the society on issues of drug abuse.
