SUMMARY Diamond-Blackfan anaemia (DBA) is a rare cause of bone marrow failure. The incidence of malignancy and endocrine complications are increased in DBA, relative to other inherited bone marrow failure syndromes. We describe an adult woman with DBA who developed osteoporosis and avascular necrosis (AVN) of both distal femora. Such endocrine complications are not uncommon in DBA, but under-ap...

Aryl hydrocarbon hydroxylase in mouse skin epidermis was inducible by topical applications of 1,2,5,6-dibenzanthracene (DBA), 7,12-dimethylbenz[a] anthracene (DMBA), and 5,6benzoflavone. 7,8-Benzoflavone given topically inhibited the enzyme activity; phénobarbitalgiven topically had little or no effect on this enzyme activity. 7,8-Benzoflavone given at the same time as DMBA inhibited the forma...

suspensions from DBA/2 mice. Under the same conditions any immune response in DBA/2 mice was doubtful. Pretreatment with normal or x-radiated normal DBA/2 spleen did not protect CDBA animals against L1210 challenge. DBA/2 skin grafts were rejected by a proportion of normal CDBA animals and by CDBA animals preimmunized with L1210. The rejections were late—about 140 days for normal animals and ...

RATIONALE The extent of heart disease varies from person to person, suggesting that genetic background is important in pathology. Genetic background is also important when selecting appropriate mouse models to study heart disease. This study examines heart growth as a function of strain, specifically C57BL/6 and DBA/2 mouse strains. OBJECTIVE In this study, we test the hypothesis that two str...

Abuja the capital city of Nigeria has experienced rapid development and high influx of people with the implication of increased generation of noise. Hence the need to evaluate the noise pollution level of the city. Measurement of equivalent noise level was carried out in 35 locations around the city using a CR811C integrated sound level meter. Result showed that the day time mean equivalent noi...

BACKGROUND Development of noise-induced hearing loss is reliant on a few factors such as frequency, intensity, and duration of noise exposure. The occurrence of this occupational malady has doubled from 120 million to 250 million in a decade. Countries such as Malaysia, India, and the US have adopted 90 dBA as the permissible exposure limit. According to the US Occupational Safety and Health Ad...

The aim of this study was to determine the daily noise exposure levels in black tea processing factories and evaluate its effects on employees' occupational health safety. In study, sound pressure level dBA values were measured at ear employees each production unit three operating Artvin Province. These where measurements made consist withering, curling, oxidation, drying (boiler stove) classif...

Neonatal thymectomy (NTx) induces autoimmune gastritis (AIG) in BALB/c mice, a model for human type A chronic atrophic gastritis, but not in DBA/2 mice and rarely in CDF1 mice (a hybrid of BALB/c and DBA/2 mice). The aim of this study was to clarify the mechanisms of AIG-resistance in mice bearing the dominant trait of DBA/2. Linkage groups associated with, and cells related to AIG resistance w...
