Medical CD Required

[NICHOLAS PHILIP LAZARUS]

Does anyone know of any CD's for medical subjects such as 
pathology,immunology,serology ,medical microbiology 
,histology,haematology or any other related medical subject ?
I am currently have a friend who is studying Medical Technology as a 
diploma course and he is interested in getting a CD on any of the related 
subjects to help him in his studies.

The CD has to be for the PC as he does not have a mac.

Thanks.
