Table 1.

SAH grade and mortality are prognostic indicators, which recorded after surgery and treatment. A total of 30 rats died during or after model constructed due to severe SAH, and another 21 rats were excluded because of their low SAH grade. No death was observed in the sham group, after surgery, with mortality rates (Table 1), which were calculated as follows: sham = 0% (0 of 40), SAH = 27.27% (18 of 66), NS = 25.0% (6 of 24), Hep = 16.67% (6 of 36), Abs = 17.39% (4 of 23), Ebs = 17.65% (9 of 51), PBS = 26.92% (7 of 26), OSM = 21.28% (10 of 47) and PBS + Abs = 25% (4 of 16), OSM + Ebs = 29.17% (7 of 24). However, there were no statistically significant differences in mortality rates between treatment groups.
