Table 1.

Selected haematologic parameters from four SCA patients. The symbols MCHC and MCV in the table denote mean corpuscular haemoglobin concentration and mean corpuscular volume, respectively. S-P-I and S-P-II represent two samples of SCA patients not treated with HU, whereas S-P-III and S-P-IV represent the other two samples from SCA patients treated with HU.
