, a couple of health-care stocks, were among the small-cap winners Thursday.

Accelr8 shares rocketed 48% after the Denver-based company received a notice of allowance on a patent covering methods used in its BACcel rapid diagnostic platform, which quickly identifies major multiple drug resistant bacteria, or "superbugs." That means the patent -- Accelr8's first for that system -- is close to being issued. Shares were up $1.18 to $3.64.

Fonar, a medical-equipment maker based in Melville, N.Y., soared 24.5% to $7.32 after Health Diagnostics ordered six of its Fonar Upright Multi-Position magnetic resonance imaging (MRI) machines. Terms weren't disclosed.
