UNC Hospitals Platelet & Plasma Donor Program: Despite increased donations in the wake of Sept. 11, UNC hospitals may face a shortage of platelets supplies in coming months. UNC Hospitals are asking healthy individuals, between the ages of 17 and 76, to donate platelets and plasma for UNC patients suffering from cancer, blood disorders and trauma. For information, call 966-2370 or e-mail Platelet@unch.unc.edu.
