[The effects of batroxobin on the healing of and microcirculatory blood flow volume in deep partial thickness burn wounds in rats].
OBJECTIVE
To investigate the effects of batroxobin on the healing of and microcirculatory blood flow in deep partial thickness burn wound in rats.


METHODS
Wistar rat inflicted by 4 cmx 4 cm deep partial thickness scalding on the back was taken as the model. Twenty male rats were randomly divided into scalding burn group and batroxobin treatment group. Cutaneous blood flow volume was measured before and at 0.5, 2, 4, 6, 12, 24 and 72 postburn hours (PBH). Scalding and residual burn wound areas were measured immediately and on the 14th and 18th postburn day (PBD). The rats were sacrificed on 30th PBD and the cutaneous samples were harvested for hair follicle counting and histological examination with LM.


RESULTS
The cutaneous blood flow volume of rats in single burn group decreased progressively during 2-72 PBHs. But in batroxobin treating group, cutaneous blood flow volume improved evidently and the wound healing accelerated obviously with increased cutaneous appendages formation.


CONCLUSIONS
Batroxobin might restore the blood circulation of stasis band of burn wound, so as to accelerate wound healing and to improve the quality of healed skin.
