Perineural dexmedetomidine effects on sciatic nerve in rat.

The present study was designed to test the hypothesis that high dose dexmedetomidine would increase the duration of antinociception to a thermal stimulus in a rat model of sciatic nerve blockade without causing nerve damage. The rats were anesthetized with isoflurane. After electromyography (EMG) recordings, right sciatic nerves were explored and perineural injections were delivered: Group D (n=7), 40μgμgkg dexmedetomidine administration, Group II (n=6), (0.

Prognostic Significance of Mitotic Activity in Noninvasive, Low-Grade, Papillary Urothelial Carcinoma.

Objective: To identify the most useful method to detect the mitotic count (MC) by comparing different techniques, to determine a cutoff value for mitotic activity (MA), and to evaluate the correlation of this value with the recurrence of noninvasive low-grade papillary urothelial neoplasm (LGPUC).

Study Design: Hematoxylin and eosin-stained slides of 55 LGPUC cases were evaluated for their MA. MC was determined using 4 different methods.
