RESUMEN
OBJECTIVE: To study the effects of deferoxamine on tissue sodium-potassium adenosine triphosphatase (Na+-K+ ATPase) activity on cerebral ischemia in rabbits. METHODS: We cared for the animals in the Pharmacology Department of the Medical School of Selcuk University in 2004. We used 30, New Zealand, 7-day-old male rabbits in the experiment. We anesthetized all the animals with xylazine hydrochloric acid and ketamine. We divided the rabbits equally into 3 groups. In group 1 (n=10) (sham group), we observed baseline levels, and did not apply ischemia. In group 2 (n=10) (untreated group) we produced cerebral ischemia by clamping the bilateral common carotid arteries for 60 minutes, and in group 3 (n=10), we administered deferoxamine (DFO) 50 mg/kg intravenously immediately after opening the clamps. RESULTS: The Na+-K+ATPase activity increased after DFO treatment (p=0.045). CONCLUSION: We conclude that Na+-K+ATPase activity in cortical brain tissue was higher in DFO-treated rabbits compared with untreated animals after ischemia.
RESUMEN
After a few reports on end-to-side nerve repair at the beginning of the last century, the technique was put aside until its recent reintroduction. The authors present their results in three patients with median nerve defects that were between 15 and 22 cm long and treated using end-to-side median-to-ulnar neurorrhaphy through an epineurial window. The follow-up times were between 32 and 38 months. Sensory evaluation involved superficial touch, pinprick, and two-point discrimination tests. Motor evaluation was completed by assessing the presence of opposition and by palpating the abductor pollicis brevis muscle. Sensory recovery was observed in all patients in the median nerve dermatome, and motor recovery was absent, except in Case 1. End-to-side nerve repair can be a viable alternative to nerve grafting in patients with long gaps between the ends of the injured nerve.
