    Cephalic index is an important feature that characterizes different races. The study aimed at comparing the cephalic indices between the two genders and to determine the stature among Okun and Ebira ethnic groups in Nigeria. The subjects were measured for cephalic length, breadth and subject height and the cephalic indices were calculated by dividing the cephalic breadth by cephalic length, and then multiply by 100. 844 subjects of Okun and Ebira origin of Kogi state were measured, 211 males and 211 femalesfor each tribe were measured. Fischer’s formula was used to determine the sample size because the population size is > 10,000. The cephalic breadth and length was measured using a spreading caliper and the subject height was measured with a stadiometer. The data was analyzed using Pearson’s Chi square analysis test for association, trends and distribution difference of the pattern (confidence level at 95%). The mean cephalic indices of both Okun and Ebira ethnic group were >75 and >70 which belongs to mesocephalic and doliocephalic group respectively. There were significant differences in cephalic indices between both ethnic groups (p<0.001). There was no significant difference in cephalic indices between males and females of each ethnic group. Stature was better predicted from cephalic indices for Ebira males (r= 0.386) when compared to the Ebira females (r= 0.127), Okun males (r= 0.296) and Okun females (r = 0.268). All predictions were significant except for Ebira females

    Histoarchitectural Study of the Cerebrum and Cerebellum of Juvenile African Giant Rat (Cricetomys gambianus Waterhouse) and Wistar Rats (Rattus novergicus) Brain
    (The Official Journal Of The Anatomical Society Of Nigeria, 2015-03) Ajao MS,; Abdulmojeed FA,; Abioye AIR,; Adana MY,; Kareem SB,; Alabi AS,; Imam A.
    African giant rats are used in some part of the world for the detection of landmines and tuberculosis from human sputum. However, in some parts of the world they are consumed as a source of protein. This study was designed to look into the histo-morphometry of the cerebrum and cerebellum in comparison with the Albino wistar rats that are mostly used as laboratory experimental animals. Eight African giant rats were captured from the wild comprising of four males and four females while the wistar rats were purchased from a local breeder at Ilorin, Kwara state. The animals were cardiacly perfused and their brains were removed for morphometric assessments and histological analysis. Result shows that the cerebral and cerebellar cortices are similar in the two animals. The cerebellar cortex has three layers (molecular, purkinje and granular) and a central core of white matter but were few differences in the population of the cells. The cerebral cortex of the two animals also has the six cell layers and the hippocampus area but there are more pyramidal cells in the hippocampal area of the African giant rat than that of the Wistar rats. In conclusion the properties of the cerebral and cerebellar cortex accounts for the behavioural pattern of the animals.

    LIP PRINT MORPHOLOGICAL PATTERN IN RELATION TO NASAL INDEX AMONG ADULTS OF EGBA, IN ABEOKUTA, SOUTH-WEST NIGERIA
    (Enugu State University of Science and Technology, 2021-06) Alabi AS,; Omoge OE ,; Kareem SB,; Imamfulani AO
    Cheiloscopy and Nasal index are important bio-anthropological parameters unique to each ethnic group. The study aimed at identifying the lip print pattern and nasal index peculiar to Egba people and their possible interrelationship. The study was conducted in Abeokuta, South-West, Nigeria, among 410 adult Egba individuals (205 males and 205 females). Nasal height and width were measured using Digital Sliding Vernier Caliper. The lip prints of the subjects were collected by gently placing a microscopic glass slide on the lip after a little application of lip gloss. The data obtained were analyzed using SPSS version 20.0 software and the statistical significance was put into consideration using one-way Analysis of Variance (ANOVA) when (P 0.05). The result showed that the predominant lip print pattern of the Egba ethnic group was Type V. The predominant Nasal Index among both sexes was 60.00 while their peculiar nasal shape was Leptorrhine, which can subsequently serve as an important anthropometric tool used in reconstructive surgeries of nose. The study revealed no significant variation among the lip print patterns of all types of nasal morphology. The existence of sexual dimorphism in the lip print pattern of the Egba ethnic group is a peculiar feature that can be relevant in determination of gender in identification of persons during crime investigations and in mass disaster which are relevant in medico-legal cases

    RELATIONSHIP BETWEEN LIP PRINT AND SEASON OF BIRTH AMONG A NIGERIAN POPULATION
    (Official publication of Enugu State University of Science and Technology, 2021-09) Alabi AS,; Olagbaye BA,; Aniyikaye BA ,; Lewu FS,; Adigun FM,; Adeleke OS,; Kareem BS,; Aigbogun E
    Some factors have been found to influence lip print patterns in individuals. The aim of this study is to evaluate the relationship between lip print pattern and season of birth in a Nigerian population. A total 764 adults were purposively selected from a two closely related tribe in the north central geopolitical zone of Nigeria. There lip prints were obtained by applying lip gloss and print on a glass slide. Each lip was divided into 6 quadrants and studied under magnifying lens. Lip print patterns were grouped using Hassan Fahmy (1977) classification. Statistical analysis was done using Statistical Package for Social Sciences (SPSS version 23). Lip print types were expressed as frequency and proportion for each lip quadrant. Correlations between male and female lip print pattern and their season of birth was done using Chi-square test. The confidence level was set as 95% while statistical significance was set at . Results showed a consistent prevalence of type III and IV in the entire upper and lower quadrant, while the least expressed were type I' and II. Qualitative analysis of association between season of birth and lip print pattern showed no significant distributional difference between those born during wet and dry season in the entire upper and lower quadrant but established that types III and IV were more prevalence in the tribe of study. These finding has provided further fact to prove that cheiloscopy is a reliable tool for personal or tribe identification.

    Sex Determination Using Tali Bones
    (Faculty of Basic Medical Sciences, University of Ilorin, Ilorin, Ilorin, Nigeria., 2024-09-30) Kareem SB,; Muyideen MK,; Ajiboye AA,; Imam A,; Ibrahim A,; Alabi AS,; Ajao MS
    The talus is an important bone used in forensic and archaeological cases for the determination of the sex of human remains because it is a preservational favored bone of the body. The study is designed to take the measurements and dimensions of dry tali to determine the sex as well as the sides of the bones. A total of 82 cadaveric bones were used. In each of the bones, measurements like tali length, breadth, widths, height, head height, head-neck length, trochlear breadth and length, length and breadth of the medial-lateral articular facet, and length and breadth of the posterior calcaneal articular surface were taken. Eleven parameters were measured on 82 bones (49 males and 33 females) obtained from the Anatomy Museum of the Anatomy Department, College of Health Sciences, University of Ilorin, Nigeria. Statistical Package for Social Sciences version 21.0 was used to analyze the discriminant function of all the measurements that were taken. The statistical analysis showed that all measured parameters were sexually dimorphic. Forty-four right tali 44 and thirty-eight left tali were found. The average accuracy for all the bones was 80.5% following the stepwise procedures from the discriminant function analysis. While the accuracy for correctly classifying the bones into males was 71% and females was 94%, the female tali bones were most often correctly classified. In conclusion, the talus bone was shown to be useful for the determination of sex.

    The Effects of Green Tea on the Body Weight and Histoarchitecture of the Testis of Adult Male Sprague dawley Rats
    (International Journal of Clinical and Experimental Physiology, 2018-09) Alabi AS,; Arokoyo R,; Oyewopo AO,; Lewu FS,; Kareem SB,; Aigbogun EO,
    Background and Aim: Green tea is an aromatic beverage derived from the cured leaves of Camellia sinensis. It is a potent herb which serves various therapeutic purposes. This study was carried out to determine the effect of the administration of various concentration of green tea extract (GTE) on the histoarchitecture of the testis of Sprague dawley adult male rat. Methods: 20 animals were divided into four groups, comprising of 5 animals each. The control group was given distilled water while the treated groups were given 2ml/kg, 4ml/kg and 6ml/kg of aqueous extract of green tea respectively for 26 days. At the end of the admin istration on the 27th day, in accordance with IACUC regulation, the animals were euthanized following the administration of AGTE after which they were dissected and the testes were excised for tissue processing. Results: There was a progressive decrease in weight of the treated animals corresponding to the increase in the concentration of green tea. The histo logical analysis showed that the GTE at 2ml/kg did not disrupt the histoarchitecture of the testicular tissue; however, there was mild to moderate degeneration at 4ml/kg and 6ml/kg respectively and this histoarchitectural distortions of the testis by of GTE may take a direct or indirect path; thus, may induce testicular dysfunction. The Feulgen stain intensity was more in the control and group 1, when compared to group 2 and 3, which is a pointer to DNA ma terial loss in testicular tissues at higher doses. Conclusion: Lower dose of GTE may seem beneficial; however higher doses pose more harm in a short period, when compared to the benefit of the lower dose on the body and testicular tissue. However, there is the need for further investigation on the role and mechanism of action of GTE on testicular cellular and tissue dysfunction and consequence on reproduction.
