Spleen function was studied in a group of 20 Kuwaiti SS patients (aged 2-12 years), using 99mTc-labeled tin colloid scintigraphy. They were screened for the alpha-thalassemia determinants which are prevalent in the Arabian Peninsula [-alpha (3.7 kb) deletion, alpha2-globin gene polyadenylation signa

✦ Synopsis
The ratio of total globin alpha to beta chain synthesis was determined in reticulocytes isolated from the blood of the members of a black family, some of whom had sickle cell trait with low blood HbS concentrations (25-30%). The results support the hypothesis that sickle cell trait individuals with low HbS concentrations also carry a gene for alpha-thalassemia.

Hemoglobin J Mexico, an alpha chain mutant, was studied in eight unrelated Algerian families. The quantities of the abnormal hemoglobin in 116 subjects are trimodally distributed: 55% in homozygotes, 31% and 38% in heterozygotes. Both hematological data and the alpha/beta chain biosynthetic ratio ar
## Abstract The in vitro synthesis of hemoglobin chains was investigated in 34 scikle cell anemia (SS) patients and five patients with Hb S‐β^o^‐thalassemia. Incubations were made for 30 minutes and for 120 minutes. Hematological and family data were also obtained. Although the 30‐minute α/non‐α to
