Comparison of two proliferation assays MTT and ltt in immunodeficient patients.

MTT assay is designed for spectrophotometric quantification of cell growth and viability without using the radiactive isotopes. The aim of this study is comparison of LIT and MTT as sensitive poliferation assays in imrnunodeficient patients. 20 immunodeficient and 20 healthy subjects were selected in this study.

Clinicopathological findings in patients with primary and secondary defects of neutrophil mobility.

Twenty-eight patients with defective neutrophil mobility were classified, largely on results of parent values, into primary (17)--mainly Shwachman's syndrome--and probable secondary (11). They presented with frequent infections and/or allergy and these symptoms were essentially similar in both groups. Neutropenia was virtually confined.
