Résumé
BACKGROUND: Data on the attitudes of medical and nursing students towards blood donation are scanty. Since this group is a potential but under-utilized source of blood donors, studying their attitudes could provide insights into donor-related behaviour and, hence have implications for donor recruitment programmes. METHODS: The attitudes towards blood donation and frequency of donation of 307 medical and nursing students were studied using a scale to measure affect, behaviour and cognition. RESULTS: The attitudes were found to be positive in all three scales. While the behaviour scale significantly discriminated donors from non-donors, no significant differences were observed in the affect and cognition scales. CONCLUSION: In a medically-oriented population, donors and non-donors do not differ significantly in their sentiments towards blood donation. Other social variables may account for donor behaviour which need to be studied further.

The efficacy of the slow thaw siphon technique for making cryoprecipitate was evaluated. A hundred consecutive bags of cryoprecipitate were subjected to analysis. The average Factor VIII:C level in donors plasma was 1.02 IU/ml with slightly lower levels of Factor VIII:C in O group persons and in the older age group. The average Factor VIII:C content per bag of cryoprecipitate was 132 units with the average Factor VIII:C yield of 57.8 per cent. Recovery of the cryoprecipitates made by this method was tested in vivo in ten haemophiliacs with less than 1 per cent activity. An average increment of 1.91 per cent in Factor VIII:C levels was obtained by infusion of 1 IU/kg body weight.

The estimation of cellularity of bone marrow was done on 212 trephine biopsies and their corresponding aspirate smears by a single observer using the visual scanning method. On applying the statistical test of agreement, it was found that the trephine biopsies and the aspirate smears were equally reliable in assessing marrow cellularity.
