The impact of intracervical hyaluronidase enzyme on cervical histomorphology in successfully detorted uterine torsion affected buffaloes

Abstract

The present study evaluated the impact of intracervical hyaluronidase enzyme on cervical histomorphology in successfully detorted uterine torsion affected buffaloes. These animals were either subjected to routine post-detorsion treatment (n=10) or in addition to routine treatment, hyaluronidase enzyme (10,000 IU; 2.5 ml at each of 3, 6, 9, 12 o’clock position of cervix) was administered intracervically immediately post-detorsion (n=10), followed by repeated administration at 6 h interval (0, 6, 12, 18 h) till complete cervical dilatation or till 24 h after detorsion. The pre-treatment cervical biopsy samples were collected immediately after detorsion and post-treatment samples were collected at complete cervical dilatation which happened within 24 h after detorsion in all the cases. Following histomorphology, the quantification of collagen fibers as mean percentage area occupied collagen out of total tissue area in pre-treatment cervical biopsy samples of all the buffaloes was revealed as 21.0±5.7. During post-treatment period, at the time of complete cervical dilatation, this value exhibited a decrease in control (9.1±2.2; P>0.05) as well as hyaluronidase group (5.8±2.1; P<0.05). In summary, collagen fiber dispersion in cervical tissue of successfully detorted uterine torsion affected buffaloes suggested their role in cervical dilatation, whereby, intracervical hyaluronidase was able to enhance the cervical tissue collagen dispersion.
