【正文】 o imitate diabetes while they are not feeding for a night,without suffering any ill effect. If researchers can identify a similar geic path in human,they may be able to develop drugs to effectively switch off diabetes. Some million people in Britain have type 2(or late onset ) diabetes,a figure that is expected to reach 4 million by 2025 as a consequence of rising levels of obesity. The tissues of people with type 2 diabetes have bee resistant to insulin (胰島素 ) so they lose the ability to cintrol sugar levels in their blood. The condition can damage the heart,eyes,kidneys ( 腎臟 ) and nerves and contribute to 5%of all deaths,according to the World Health Organization. Dolphins appear to imitate diabetes to keep high levels of blood sugar when food is rare. Like humans, dolphins need some sugar in their bloodfor the brains to function normally. VennWatson’steam analyzed 1000 blood samples from 52 dolphins while they didn’t eat anything overnight and were fed in the morn ing. At night time,the dolphins’ metabolism ( 新陳代謝 ) changed greatly and showed similar characteristics to that seen in people with type 2 diabetes. “It is our hope that this discovery can lead to new ways to treat and maybe even cure diabetes in humans, “ said Stephanie Veen Watson, director of clinical research at the National Marine Foundation in San Diego. 29.
