The effect of administration of amodiaquine on some Parameters of neurobehaviour of wistar rats

The effect of administration of Amodiaquine (AQ) on some parameters of neurobehaviour of Wistar rats was carried out. Twenty adult Wistar rats weighing between 160-190g were divided equally into four groups. Group 1 served as the control, while groups 2, 3 and 4 were the experimental groups. The control group received distilled water. Groups 2 and 3 were treated with 8.75mg/kg and 17.50mg/kg respectively of AQ for three days, while group 4 was treated with 8.75mg/kg of AQ for six days. Neurobehaviour test using the open field was carried out twelve hours after the last administrations. There were no significant differences between the control and the experimental groupsin total locomotor activity (TLA), central square duration (CSD), stretch-attend (SA) and defecation. In the central square frequency (CSF), group 3 was significantly (

Sex variations in thumbprint ridge count of a Nigerian population in Calabar Municipality

The present study aimed at determining the association between thumbprint ridge count and sex variation among Nigerians in Calabar Municipality. A total number of 300 subjects (150 males and 150 females) aged between 12-35 years participated in the study. Conventional method of using ink pad was used to collect thumbprint of both hands and analysed using magnifying lens. The study confirmed the results of some earlier works done by other researchers on fingerprints. It further established the distribution proportions of thumbprint for both hands in both sexes for the population. The uniqueness of fingerprint to individuals was reaffirmed as no two thumbprints were identical among the 300 subjects under study. These results show that the order of prevalence are as follows; among males, in whatever combination of thumbprint pattern, whorl is the most occurring, followed by loop and arch. Among females, in whatever combination of thumbprint pattern, loop is the most occurring followed by whorl and arch. The result equally showed the mean thumbprint ridge count of females to be lower than that of males (20.91 as against 27.85 respectively). The difference in pattern between left and right hands in females was significant. In conclusion the thumbprint ridge count shows gender dysmorphism in the Nigerian population.Keywords: Fingers, epidermal ridges, thumbprint ridge coun

Cephalofacial Indices of the Ibo and Yoruba Ethnic groups in Southern Nigeria

Cephalofacial analysis is an important parameter useful anthropologically to ascertain racial, ethnical and sexual differences. This work aimed at determining cephalic and facial indices and the anatomical types of head and face found among the Ibo and Yoruba tribes. Study was cited in two geographical locations in southern Nigeria depending on the ethnic group. Five hundred human subjects were randomly selected,  comprising 300 and 200 subjects of the Ibo and Yoruba ethnic groups respectively with age range of 18-35 years. Results obtained showed that Ibo males and females had mean cephalic indices of 81.79±0.43 and 81.68±0.52 respectively and facial (prosopic) indices of 75.49±0.50 and 73.76±0.54 respectively while the Yoruba males and females had mean cephalic indices of 80.40±0.49 and 78.47±0.66 respectively and facial indices of 77.60 ± 2.82 and 73.72±1.05 respectively. Based on the Cephalic Index, the dominant head form found among the Ibo ethnic group was brachycephaly while the Yoruba ethnic group had a head form ranging from brachycephaly to mesocephaly. Facial indices showed dominant hypereuriprosopic face type for the two ethnic groups. The cephalic index only showed sexual dimorphism  in the Yoruba ethnic group but the facial index  showed significant gender difference in the two ethnic groups studied.Data got from this research could be useful in forensic medicine and reconstructive surgeries.
