We aimed to develop a double-injection model of intracerebral hemorrhage (ICH) in rabbits and to evaluate it as a tool for investigating post-ICH brain injury. Rabbits were injected with 300microL fresh autologous whole blood into the right basal ganglia. ⋯ At 1, 3 and 7 days after ICH, there were significant differences in the total neurological scores (p<0.01) and BWC (p<0.01) between a sham-operated group and the ICH group. These findings suggest that the model produces a persistent neurological deficit, hematoma volume and perihematomal edema and closely mimics human hypertensive basal ganglia ICH; it is a controllable and reproducible hematoma that lends itself to quantitative investigation.

Erythropoietin (Epo) has neuroprotective activity in a variety of settings. Thus, we investigated whether Epo has a role in the functional recovery of rats after facial nerve injury. The right facial nerve of 24 Wistar rats (6 wks old) was crushed twice at the level of the stylomastoid foramen, for 30 s each time, using jeweler's forceps held perpendicular to the nerve. ⋯ There was no significant difference between low dose Epo-treated rats (1,000 U/kg body weight) and the placebo-treated rats. These results suggest that high dose Epo can promote the functional recovery of rats following facial nerve injury. Further studies are warranted to probe alternative treatment schedules (dose, mode of administration), underlying histological mechanisms and combination treatment with additional neuroprotective factors.

Randomized Controlled Trial Comparative Study
Use of skin glue versus traditional wound closure methods in brain surgery: A prospective, randomized, controlled study.
Traditional skin sutures (TSS) and metal skin clips (SC) are the most common devices utilized for closure of surgical incisions. They are safe and effective, although they require instruments to apply them, are time consuming and, above all, create an extra staff and cost burden for removal of sutures/staples. The ideal incision closure should be simple, effective, safe, rapid, inexpensive, painless, cosmetic and bactericidal. ⋯ The mean application time of the tissue adhesive was significantly faster than that of the standard suture (115s vs. 300s; p<0.001); in the skin clips subgroup it was 105s. Our study suggests that the new NCA tissue adhesive is a safe, effective and reliable skin closure for neurosurgical procedures in the supratentorial region; it also achieves optimal cosmetic results, is less time consuming to use and has greater patient satisfaction. However, further studies with a larger number of patients are necessary to corroborate these results.
