Trends in Cardiovascular Health Metrics among Korean Adults.

Background: American Heart Association (AHA) defined 7 cardiovascular health metrics for the general population to improve cardiovascular health in 2010: not smoking; having normal blood pressure; being physically active; normal body mass index, blood glucose, and total cholesterol levels; and eating a healthy diet. To investigate trends in cardiovascular health metrics in Korea, we used data from the third and fourth Korean National Health and Nutrition Examination Surveys.

Methods: We defined seven cardiovascular health metrics similar to the one defined by AHA but physical activity, body mass index, and healthy diet were properly redefined to be suited for the Korean population.

Apoptosis in growing hair follicles following gamma-irradiation and application for the evaluation of radioprotective agents.

The usefulness of apoptotic fragments assay for investigating the radiation response of hair follicles and evaluation of radioprotective agents was examined in ICR mice. The extent of changes following 100 cGy (1000 cGy/min) was studied at 0, 2, 4, 8, 12, 16 or 20 hours after exposure. The maximal frequency was found 12 hours after exposure.
