An ethnobotanical survey of Bauchi State herbal plants and their antimicrobial activity.

A survey of medicinal plants used locally in the treatment of various diseases was carried out in Bauchi State-Nigeria. A total of 84 medicinal plants were listed. Preliminary antimicrobial activity of the aqueous extracts of the plants was investigated. The results indicated that out of 84 plants, 75 exhibited antimicrobial activity against one or more of the test organisms at a concentration of 200 mg/ml. The extracts were found to show potentially interesting activity against Proteus mirabilis, Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli.

Infraglottic and bronchial infections.

Concerns over infraglottic and bronchial infections have been a source of anxiety and lost sleep for many children, parents, and physicians. The annual incidence of lower respiratory tract infections in children younger than 6 years old exceeds 5 million in the United States. Despite the frequency of these infections, the often common and nonspecific clinical symptomatology, variable severity, and changing epidemiology over time all have contributed to our understanding and misunderstanding of these disorders.

Adolescents' visual preference for color over form.

This study is concerned with the visual preference for color over form among the Yoruba adolescents of Nigeria. The hypothesis is that Yoruba adolescent boys are more likely to demonstrate superior performance in a task involving cultural differences in visual selective attention preference for color over form than girls. One hundred 16-year-old adolescent boys and girls were randomly drawn from two secondary schools for this study. The instrument used was the Visual Selective Attention Color-Form Matching Experiment. Computation was carried out with a chi-square 2 X 2 contingency analysis. Results indicated that the hypothesis reached a .001 statistical level of significance. The theoretical implications of the findings are discussed.

Performance of normal and disabled Nigerian students on a selective attention task.

To determine to what extent disabled students may be selected and integrated into the regular schools in Nigeria, normal and blind students were compared for differences in selective attention in a task involving letters and numbers. It was predicted that, because of the sociocultural stigma attached to blindness, normal students (n = 21) would perform better than blind students (n = 21). The hypothesis was substantiated.

Cultural determinations on the auditory split-span technique of selective attention.

Cultural differences in selective attention among Ibo and Yoruba adolescents of Nigeria were examined with the auditory split-span technique. It was predicted that Yoruba would perform better than Ibo in a task involving auditory discrimination of digits alternated with letters. A group of 200 16-year-old boys and girls was randomly drawn from four secondary schools of both ethnic groups to represent a wide range of socioenconomic environments. Factorial analysis and analysis of variance showed no significant differences and did not substantiate the hypothesis. Theoretical implications of the findings were elaborated.
