The research attempted to develop sponge wound of Chitosan which have a low toxicity, biocompatibility, biodegradability. And raise hemostatic to dimensional let cell will be grown even and bit granuloma, aspiration the more prefect anticipative effect of the wound's apocatastasis. The sponge wound by way of test have a great inflexible's strength is 4.16N and average porosity is 59.71%. After the Chitosan film dipped in pollen Typhae. As far as the animal test show when the wound apply to sample at the six days the wound surface to callus.
