Alpha-beta thalassaemia.

In a Greek Cypriot family in which genes for both alpha and beta thalassaemias were expressed, haematological and biosynthetic investigations indicated that one family member was homozygous for beta thalassaemia and had alpha-thalassaemia1 trait. The concurrent inheritance of an alpha-thalassaemia gene in the beta-thalassaemia homozygote seemed to have modified his degree of chain imbalance and to have reduced the clinical severity of the disease.

Some surgical aspects of homozygous beta-thalassaemia.

The surgical aspects of the management of patients with homozygous beta-thalassaemia are reviewed, and the operative findings in 10 patients with the disease who underwent splenectomy are described. Postoperatively, blood consumption was reduced and there was a longer time interval between transfusions needed to maintain the haemoglobin level. Hyperplastic lymph nodes containing erythropoietic elements are always present, and the first reported case of extrabiliary obstructive jaundice caused by this tissue is included. All the patients survived for 2-3 years after treatment and there were no serious infections. All received prophylactic oral penicillin after surgery. Cholelithiasis was not found. Two malleolar ulcers were successfully grafted with split skin after preparation of the craters with silver sulphadiazine cream.

Embryogenesis of an insect nervous system. I. A map of the thoracic and abdominal neuroblasts in Locusta migratoria.

Maps of the thoracic and abdominal neuroblasts have been prepared by reconstruction from serial sections of timed Locusta migratoria embryos. The maps are bilaterally symmetrical, periodic and consistent for embryos of the same age, with a fundamental arrangement of 7 rows of 4-10 cells plus 1 median neuroblast per segment. A map of 60 + 1 cells is repeated in each of the three thoracic segments, with an additional median cell developing late at the anterior end of the prothorax. The arrangement in the abdomen is similar, with 56 + 1 cells per segment. Neuroblasts differentiate and subsequently degenerate in an antero-posterior sequence, but construction of the thoracic ganglia involves a delayed degeneration of part of the original set in these segments. The maps show that the neuroblasts are as reliable in their number and arrangement as the adult cells they produce. The number of neuroblasts used in constructing the relatively complex thoracic ganglia is similar to that which produces the simpler abdominal ganglia. Some motorneurons have the same parent neuroblast. The maps are intended as a first step in an analysis of the relation between the progeny of different neuroblasts and the family of neurons which each neuroblast produces.
