Chronic tiredness and idiopathic chronic fatigue--a connection?

Evidence is adduced to support the proposal that pathological fatigue is a consequence of impaired capillary blood flow resulting in inadequate oxygen delivery, which is in accordance with physiological concepts of fatigue. Case reports are presented.

Changes in red cell shape in healthy elderly subjects taking low dose fish oil: pilot study.

OBJECTS: to investigate the effects of low dose fish oil on red cell shape and blood pressure in healthy elderly subjects during a 16 week treatment and an eight week follow-up. METHODS: red cell shape analysis by scanning electron microscopy with data analysis by repeated measures analysis of variance. RESULTS: in the preoil blood samples the percentage of cells with surface changes was much higher than that of younger healthy subjects (24.0% vs 14.4%). While taking fish oil the percentage of cells with surface changes declined to a minimum at the end of the eighth week, steadily increased during the next eight weeks then declined during the eight week follow up. Mean blood pressures were not altered by the fish oil although that of five subjects taking different types of antihypertensive drugs tended to show greater fall in blood pressure than those not on drugs. CONCLUSION: that dietary supplementation with low dose fish oil was associated with changes in red cell shape. The observed changes are currently inexplicable.
