...that use rhesuses for testing the effects of diet, drugs and other chemicals in relation to a wide variety of human diseases, notably cardiovascular disorders and cancer. Two important studies involve examination of the rhesus fetus while it is still in the womb, letting the pregnancy continue and checking hemoglobin changes that occur about the time of birth, which may be significant in relation to sickle-cell anemia...
Carbon monoxide is a noxious gas which binds hemoglobin and prevents the uptake of oxygen. When an athlete is exposed to moderate amounts of CO he may suffer headaches and nausea, decreased visual acuity and reduced maximal work rates. As a consequence, the athlete is not able to judge time intervals correctly and his response time is decreased. In addition the athlete risks coronary artery disease. Harvard athletes are exposed to significant amounts of carbon monoxide when exercising in Watson Rink or running along the Charles--and the effects are magnified due to their increased breathing rate...
...hard-breathing Harvard hockey team these levels are dangerous. For instance, a Harvard iceman whose ventilation rate reaches 25 litres per minute after 80 minutes, at exposures of 60 ppm will incur a 10 per cent carboxyhemoglobin level--10 per cent of his oxygen carrying hemoglobin is bound by carbon monoxide. This means that the Harvard player is receiving oxygen as if he were at 12,000 feet above sea level...
...Harvard's hockey team should submit to complete EKG exams, and pre-season and post-season hemoglobin and carboxyhemoglobin level counts...
Kafatos believes that the artificial gene could be used to make rabbit hemoglobin. But his team is more interested in learning why the sequence of nucleotides in this gene works to order the production of hemoglobin in blood cells but not in other cells. That knowledge would bring scientists still closer to learning the secret of life...
