    Author: Zhou G, Huang G, Ren L.
    Journal: Zhongguo Xiu Fu Chong Jian Wai Ke Za Zhi; 1997 Mar; 11(2):76-9. PubMed ID: 9867960.
    Abstract:
    In order to investigate the histological and stereological change of the rapidly expanded skin tube, 15 Japanese Long Ear Rabbits were divided into 3 groups: (1) Rapid expansion group, injecting once a day for 7 days; (2) Routine expansion group, injecting every 3 days for 21 days and (3) Control group, no expander implanted. The results showed that: in the rapid expansion group, the thickness of the epidermis and dermis were both increased, fibroblast proliferation was active, a large amount of new capillaries was observed, the collagen fiber was in loose type, and the mitochondria and rough endoplasmic net of epithelial cell were increased. In the routine expansion group, similar changes were observed. The vascular density and volume fraction were significantly higher in rapid expansion group than those in the control group (P < 0.05). It was concluded that the rapid expansion of skin tube was feasible.
