Fifty five sickle cell anaemia (SCA) patients at the Kenyatta National Hospital were studied
with a view to elucidating their cardiovascular status. Their age range was 13 to 27 years
(median 18.9 years). They comprised 27 males and 28 females and their mean
haemoglobin concentration was 8.5+/-1.4 g/dl. Haemoglobin level of 8.0-9.9 g/dl seen in 30
patients was noted to confer the lowest incidence of exertional dyspnoea and palpitation.
Similarly, patients with this haemoglobin level had the lowest mean heart rate. The mean …

Various animal models have been used to investigate the normal and reparative properties
of the knee meniscus. Yet, only limited data on meniscal biomechanical properties of various
animals are available. It was therefore the objective of this study to compare measurements
of meniscal biomechanical properties between six species: human, bovine, monkey, canine,
sheep, and porcine. Uniaxial confined compression tests were conducted on 1-mm-thick, 4-
mm-diameter meniscal discs, and the viscoelastic creep deformation was obtained. Two …
