Fig. 4.
Histological evaluation of tail and sciatic nerves after nerve block. (A) Normal tail nerves were evaluated by hematoxylin–eosin (HE) staining. (B) Tail nerves of rats from 1% QX-314 + 4%EI + 42°C group were stained by HE staining. (C) Normal sciatic nerves of rats were stained by HE staining. (D) Sciatic nerves of rats from 1% QX-314 + 2% EI + 44°C group were stained by HE staining. (E) Normal sciatic nerves were stained by solochrome cyanine staining. (F) Sciatic nerves of rats from 1% QX-314 + 2% EI + 44°C group were stained by solochrome cyanine staining. (G) Positive expression of CD-68 (macrosialin) (arrows) in sciatic nerves was shown by immunohistochemistry. (H) Expression of CD-68 in normal sciatic nerves was shown by immunohistochemistry. (I) Expression of CD-68 in sciatic nerves from 1% QX-314 + 2%EI + 44°C group was shown by immunohistochemistry. EI = emulsified isoflurane.
