ABSTRACT
The efficacy of homologous plasma-stored tendon grafting in the superficial digital flexor tendon severed in the mid-metacarpal region was evaluated in 10 donkeys. Experimental tenectomies were performed, followed by grafting using plasma-stored tendon and human amniotic membrane encasement in group I (n=8) but no grafting or encasement in group II (control) (n=2). Gross observations in group I showed no peritendinous adhesions, except in one animal, while control animals showed thick fibrous adhesions and thickening at both the cut ends. Histologically, in the grafted tendon there was normal healing tissue at the junctional sites with negligible collagen fibre and mild regressing inflammatory reaction by day 15. By day 30 there were a great number of blood vessels but without any inflammatory reaction. The healing tissue at the grafted site and the adjoining paratenon was more mature. The fibroblastic activity appeared to be both extrinsic and intrinsic in origin. By day 60 fibroblastic activity was negligible and the healing tissue at the distal graft and host tendon junction site was at a more advanced stage of maturation and showed early fasciculi/bundle formation. Healing tissue at three months showed collagen fibres fasciculi/bundle comparable to normal tendon architecture. Tendon appeared histologically normal at four months after grafting.

Nine adult bullocks were used for this study. The auricular artery was found to be convenient for collecting arterial blood samples. Samples were also taken from the jugular and auricular veins. The mean values of blood gas analyses from these animals are recorded.

Various thoracic disorders were radiographically diagnosed in 362 cattle and buffaloes, which accounted for 18.7% of total cases involving these 2 species. Of these 362 cases, diaphragmatic hernia accounted for about 42%, tuberculosis 18% and bronchopneumonia 15%. Other disorders included metastatic neoplasia, pericarditis with or without foreign-body involvement, hydrothorax and foreign bodies.
