This study reports the results of a survey of the available holdings of information resources on Ibibio culture in the University of Uyo Library and Akwa Ibom State Library. The specific objectives of the study were to determine the different size of information resources on funeral, fattening (Mbobo), taboos, myths as well as dissemination in the University of Uyo and Akwa Ibom State Libraries. Survey research design was used for the study. 3,854 information sources in the University of Uyo and Akwa Ibom State Libraries constituted the population of the study, with all estimated 2,276 (100%) forming the sample size of the study. Checklist was used to obtain data for the study. Chi-square was used for the data analysis. The major research findings based on the postulated objectives of the study revealed that there was a significant difference in the information resources available in the University of Uyo Library and Akwa Ibom State Library. The study concluded that libraries must oversee additional problems and increase the acquisition of information resources on Ibibio culture to further cub the dwindling nature of its collection and possible extinction of this information resources.

A fairly high activity of a relatively heat-resistant thiaminase was detected and characterized from the pupae of an African silkworm Anaphe spp. which had been the putative cause of a seasonal ataxia and impaired consciousness in Nigerians. The thiaminase in the buffer extract of Anaphe pupae was type I (thiamin: base 2-methyl-4-aminopyrimidine methyl transferase EC 2.5.1.2), and the optimal temperature and pH were 70 degrees C and 8.0-8.5, respectively. Based on gel filtration chromatography, the molecules were estimated to be 200 kDa. Second substrates which could be utilized by the thiaminase were pyridoxine, amino acids, glutathione, taurine and 4-aminopyridine. Thiamin phosphate esters were inactive as substrates. This is the first report describing an insect thiaminase. Our results indicate the necessity of thorough heat treatment for the detoxification of the African silkworm, making the worm a safe source of high-quality protein. [ABSTRACT FROM AUTHOR]
