Objective: To study the effect of the organic substances on adenosine deaminase
(ADA) activity in normal and abnormal cerebrospinal fluid (CSF).
Methods: Various concentrations of 2-mercaptopurine, Ameā€¯tycine, Adenosine
analogues (Guanine, Thymine ) and ATP were tested to see their effect on ADA
activity in normal and abnormal CSF.
Results: ADA activity in normal and abnormal CSF was remarkably decreased with
the increasing of concentrations of substances tested.
Conclusion: These effects may have important therapeutic implications. (Rawal Med
