Does giving blood benefit the donor?
Further to the answers given in NI 282 researchers in Finland and the US have good reason to believe that donating blood on a regular basis actually confers major health benefits.
Dr Jerome Sullivan from the Veterans Affairs Hospital in Charleston, North Carolina proposed in 1981 that iron is the major risk factor in cardiovascular disease. He noticed that younger women don’t get heart disease, even if they have a hereditary condition that gives them extremely high cholesterol levels. After the menopause, however, the risk increases to match that of men. Dr Sullivan believes that this is because younger women menstruate and therefore do not accumulate excess iron in their tissues until after the menopause. Men accumulate it from the age of 20 onwards.
Recent research at the University of Kansas has supported Dr Sullivan’s theory by showing tha t men who donate blood three times a year reduce their risk of cardiovascular disease by 50 per cent. There is also evidence to suggest a reduced cancer risk of 40 per cent.
The American findings are backed up by other studies at the University of Kuopio in Finland.
This news does not mean that cholesterol has no part to play in heart disease. Rather it means that the big biochemical picture is more complicated than we first thought. It is certainly good news for blood banks which are always in need of new donors!
Is there an organization that recycles computers and small electrical goods?
Over 400 tonnes of computer equipment is discarded each week in the ‘Square Mile’ of the City of London alone. Cyber-cycle is a non-profit-making company which will collect obsolete computer equipment from businesses, refurbish it and sell it on – with guarantees – to schools and community groups at low cost. Cyber-cycle can be contacted on 0171 241 4111.
Another outfit that recycles computers is Mana Organization, Unit E, Ashburton Estate, Ross-on-Wye, Herefordshire, England.
