Haemoglobin and red cells in the human foetus. II. The red cells.

In a previous paper (Walker and Turnbull, 1953) we have demonstrated the haemoglobm levels and red cell count in the cord blood of the human foetus throughout pregnancy. From the 10th week to the 24th week the red cell count doubles (from 1,500,000 to 3,000,000), but the haemoglobin rises only from 9 to 15 g. After the 24th week, the red cell count continues to rise till at 40 weeks, in the wel...

Haemoglobin and red cells in the human foetus; III. Foetal and adult haemoglobin.

In 1866 Korber found chemical differences between haemoglobin obtained from human placental blood and that from normal adult blood. Since then it has been clearly demonstrated that there are many important differences between human and animal and between foetal and adult haemoglobins (Kroger, 1888; Bischoff and Schulte, 1926; Haurowitz, 1930, 1935; Trought, 1932; Brinkman, Wildschut and Witterm...

The Specific Heat and the Heat of Compression of Human Red Cells, Sickled Red Cells, and Paracrystalline Rat Red Cells

The investigation of two thermal properties of red cells throws some light on whether sickling is a process involving the crystallization of a relatively insoluble hemoglobin. These properties are the specific heat and the heat of compression, both of which would be expected to become numerically less if the hemoglobin of the red cell were to crystallize. In the case of paracrystalline rat red ...

Human red blood cells-1

Biochemists and cell biologists, who are interested in membranes, tend to regard the human red blood cell ambivalently. On one hand, red blood cells lack nuclei and the various intracellular organelles, yet that are highly specialized for a particular respiratory function. On the other hand, the human red blood cell presents an excellent model for membrane transport function.
