Pregnant Women Warned About ACE Inhibitor
Some of the most commonly used medicines for high blood pressure are drugs called ACE inhibitors. Doctors have given these drugs to patients for twenty-five years. A government study in the United States found that the use almost doubled between 1995 and 2000.
Doctors have known for years that women should not take ACE inhibitors during the last six months of pregnancy. The medicine can injure the baby. ACE inhibitors, though, have been considered safe when taken during the first three months. But a new study has found that women who take these drugs early in their pregnancy still increase the risk of birth disorders.

[单项选择]In the early 1960s Wilt Chamberlain was one of only three players in the National Basketball Association (NBA) listed at over seven feet. If he had played last season, however, he would have been one of 42. The bodies playing major professional sports have changed dramatically over the years, and managers have been more than willing to adjust team uniforms to fit the growing numbers of bigger, longer frames.
The trend in sports, though, may be obscuring an unrecognized reality: Americans have generally stopped growing. Though typically about two inches taller now than 140 years ago, today’s people—especially those born to families who have lived in the US for many generations—apparently reached their limit in the early 1960s. And they aren’t likely to get any taller. "In the general population today, at this genetic, environmental level, we’ve pretty much gone as far as we can go," says anthropologist William Cameron Chumlea of Wright State University. In the case of NBA player
