HealthWise at 5 From 1.4

  • Healing Heart

There's more evidence today of the heart's power to heal itself. A new study shows heart muscle cells can regenerate even in a transplanted heart. Researchers studied male patients who underwent heart transplants from female donors. They found that new muscle cells generated in the heart contained Y-Chromosomes, which could only have come from the female donor. The scientists are calling the new cells, Hybrids since they're formed from a merging of the male patient and the female donor. It has long been thought that once heart muscle was damaged in a heart attack, it was dead forever. Now, researchers say this study in the New England Journal of Medicine indicates that this could change the way doctors think about Heart Attacks. The research was done by New York Medical College and funded by National Institutes of Health.

  • Too Much of a Good Thing can be Bad

You've heard too much of a good thing can be bad for you. That seems to be proven now about Vitamin A. A new study shows too much Vitamin A can block the benefit of calcium and lead to an increased risk of hip fractures in older women. The findings come from a study of 70,000 postmenopausal women. Researchers say those with the highest intakes of Vitamin A both from diet and supplements had double the incidence of hip fractures than other women. The study is in this week's Journal of the American Medical Association. More info can be found on the web by ( clicking here).

  • Birth Order and Allergies

You might not like being the baby of the family, but you probably have fewer allergies than your siblinns. A study at Michigan State University found that firstborn babies had higher levels of a key immune protein associated with allergies. It's believed that hormonal changes in the mother during each pregnancy affect the levels of the protein. Experts in London were the first to notice the effect of birth order on health when they noted the youngest family members suffered less from Asthma, Hay Fever, and Eczema
