Abstract
Incisional wounds of the same lengih and depth. were made on sldn
between dorsal fin and the lateral line canal of Clarias batrachus and
the pattern of wound closure has been studied histologically. Following
infliction, a marked change in the colour of the skin surrounding the
wound was observed which lasted for about 30 h and. restored
thereafter. Mucus and blood cells plugged the wound gap shortly after
infliction. The . epidenuis surrounding the wound was ·found to be
detached from the basement membrane. !\lass movement of epidermal
cells was observed from both side of the wound gap. The epidermal
cells at the margin of the wound became hypertrophized. The epidernlis
beca.Ine normal by 32 days. The dealing of subepidermal tissue indicated
degenerative and ·regenerative changes of muscle fibres. The mucus
and blood cells were accumulated in the wound gap and later fine
blood vessels. were forxned. Gradually granulation tissue was formed
and fibroblasts and myoblasts appeared. Myoblast differentiated into
muscle bundles. The epidermal repair was completed within 85 days.
