ObjectiveTo investigate the potential diagnostic value of plasma signal peptide, CUB (complement proteins C1r/C1s, Uegf, Bmp1) domain, epidermal growth factor (EGF)-like 1 (SCUBE1) protein in experimentally induced testicular torsion (TT).Materials And MethodsIn this randomized, controlled, experimental study, 24 mature male Wistar rats were divided into four groups: 2- and 4-hour control (groups I and III, respectively), and 2- and 4-hour torsion (groups II and IV, respectively) groups. Torsion was performed by rotating the left testis 720° clockwise and maintained by fixing the testis. Plasma SCUBE1 levels and histopathological damage scores were compared.ResultsThere was significantly greater histopathological damage in the 4-hour torsion group compared with the other groups. SCUBE1 levels in this group were also higher than those in the other groups, and the difference was significant. There were significant correlations between histopathological scores and SCUBE1 levels.ConclusionSCUBE1, a novel marker of platelet activation, is elevated in TT. According to our results, platelet activation may play an important pathological role in tissue injury associated with testicular ischemia. Plasma SCUBE1 measurement may have diagnostic, therapeutic, or prognostic value in TT.Copyright © 2015 Elsevier Inc. All rights reserved.
