Objective: To evaluate acupuncture therapeutic regimens on histomorphological changes of muscle injury healing in dog. Design: Prospective randomized experimental study. Animals: A total of 10 young adult clinically normal male cross
breed dogs weighing 26±4.4 kg and 30±4.2 months old.
Methods: All dogs were anaesthetized with 5% thiopental sodium and maintained with 1% halothane. A piece of 3 cm in length, 1 cm in width and 1 cm in depth of right biceps femoris was removed in all of them. Then they were divided into two groups of 5 animals
each. Acupuncture treatment was given daily for 10 minutes for
two weeks in experimental group by locating acupoints (GB3O,
BL4O, ST36), where as no treatment was given in control group till end of 60 days of observations period. Biopsy sample was collected from each case for histomorphological study which
were stained with H & E stain.
Result: There was the least inflammatory cells, with regular and parallel arrangement of collagenous fiber in experimental group as compared to control one in which sample of inflammatory cells, with irregular unparallel arrangement of collagenous fiber was
quite obvious.
Conclusion: Acupuncture therapeutic regimens for two weeks period had positive and stimulatory effect on muscle tissues formation
comparatively with the least inflammatory cells with regular and
parallel collagen fiber arrangement in experimental group.
Clinical relevant: Acupuncture as a physical method of therapy is quite effective on muscle healing and faster remodelling of muscle
