In this study, we evaluated the effects of trapidil on crush injury by monitoring nitric oxide, malondialdehyde and transforming growth factor-Beta2 levels and by transmission electron microscopy in the rat sciatic nerve. The sciatic nerve was compressed for 20 sec by using a jewelers forceps. Trapidil treatment groups were administrated a single dose of trapidil (8 mg/kg) intraperitoneally just after the injury. The crush and crush + trapidil treatment groups were evaluated on the 2nd, 7th, 15th, 30th and 45th days of the post-crush period. On the 7th and 15th days, damage in thin and thick myelinated axons, endoneural edema and mitochondrial swelling were less severe in the trapidil group histopathologically. These findings supported the idea that trapidil prevented cell damage and edema at the injury site. Day/group interaction with regard to serum nitric oxide, malondialdehyde and transforming growth factor-Beta2 levels did not show significant changes.

The relation of the nerves with the piriformis muscle in the deep gluteal region examined in 50 buttock from 18 male and 7 male newborn cadavers. The nerves were found in usual position in 74% of sides, while one or more nerves perforated the piriformis in 16% and, unusual location of the nerves with intact piriformis was in 10% of sides. Abnormal located nerves are utilised in view of whether originating from dorsal or ventral part of the sacral plexus.
