Abstract: AIM: To study the effects of co-amino acids extracted from silkworm chrysalis on nourish and concrescence of wound in surgical hurt rats.METHODS: The mode of rats was made by surgical operating.The rats'condition, variety of bodyweight, tensile force of skin, concentration of HYP in the wounded skin, TP and ALB, and nitrogen contents of liver were observed after feeding co-amino acids extracted from silkworm chrysalis for 14 days.RESULTS: The co-amino acids extracted from silkworm chrysalis could heal up the wound quickly and rectify the nitrogen balance.CONCLUSION: The co-amino acids extracted from silkworm chrysalis had the effect of accelerating the wound's concrescence.So we should make the best use of silkworm chrysalis.

Key words: silkworm chrysalis, the co-amino acids, concrescence of wound, nutrition
