INTERACTION OF ANTIMALARIAL DRUGS (PYRIMETHAMINE AND SULPHADOXINE) WITH NORMAL AND SICKLE HAEMOGLOBINS: A UV-VISIBLE STUDY
ABSTRACT Crude haemoglobins were extracted from blood samples of identified individuals of normal (AA), sickle trait carrier (AS), and sickle (SS) by employing centrifugation techniques. The crude haemoglobins were dialysed at 4oC for 12hr against 50mM Tris-HCl buffer of pH 7.2. The effects of pyrimethamine and sulphadoxine on the haemoglobins in the presence and absence of sodium dodecyl sulphate (SDS) were studied at pH 5.0 and 7.2 with uv-visible titration ...
