Abstract

The aim of this study was ultrasonographic evaluation, subjective and objective or quantitative, of the
SDFT core lesion in donkeys treated with intra lesional injection of PRP. Subjective evaluation was
performed by assessment of fiber echogenicity score (FES) and fiber alignment score (FAS).
Quantitative evaluation was performed by gray scale histogram analysis and measuring of core lesion
cross section area (CSA). The present study was carried out on two groups (Group-I) 12 donkeys treated
by intra-tendenious injection of freshly prepared (PRP) and (group-II) 7 donkeys as control group and
subjected to intra-tendenious injection of normal saline (Placebo). Ultrasonographic assessment were
performed before induction, 5^th, 15^th, 30^th, 45^th, 60^th and 90^th days post induction of core lesion. The PRP
treated group revealed significant (p ≤ 0.05) improvement of FES and FAS at 15^th, 30^th, 60^th and 90^th
days and at 30th days post induction, respectively. Moreover, there was significant improvement of the
core lesion CSA and theme an gray scale histogram during all time points to reach near to the normal
value at the end of the study. The mean gray value of the PRP treated group was significant (p ≤ 0.05)
higher than that of control group at all-time points of the experiment. The obtained subjective and
quantitative ultrasonographic assessments in the present investigations proved that these parameters
could be valuable in the evaluation of SDFT core lesions and monitoring the treatment of tendopathy in
equines.
