To study the changes of the expression of growth-associated protein-43 (GAP-43) and pathology in temporal infarction of rats photochemically induced and the effects of batroxobin. Methods: immunohistochemical technique and hematoxylin-eosin stain was used to show the changes of the expression of GAP-43 and pathology. Results: In infarction group, GAP-43 expression was markedly increased on the infarction and surronding tissues at 24h cerebral infarction. The expression reached peak level at 72h after cerebral infarction and was decreased at 7d after cerebral infarction. However, in batroxobin-treated group, GAP-43 expression was increased and the pathological changes were much slight as compared with infarction group. Conclusion: The expression of GAP-43 increases in infarction of temporal neocortex and batroxobin promotes the expression of GAP-43 and ameliorates the pathological changes in infarction of temporal neocortex.

Objective: To investigate the mechanism of the effect of Moist Exposed Burn Therapy (MEBT) and Moist Exposed Burn Ointment (MEBO) on the spontaneous repair and healing of superficial third degree burn wound involving fatty layer. Method: A series of skin tissue samples were taken from deep burn wounds of 2 cases. Immunocytochemistry method, biotin avidin DCS system, and indirect immunofluorescence technique were applied. Mouse anti human keratin type 19 monoclonal antibody was used to detect regenerative epidermal stem cells in wound tissues. Results: Epidermal regenerative stem cells emerged at 24 hours post burn, and the number of epidermal regenerative stem cell increased on day 4 post burn. On days 7 and 14 post burn, the number of epidermal stem cells increased to the peak level. On days 21 and 28 post burn, it decreased and disappeared gradually as burn wound progressed to healing. Conclusion: MEBT/MEBO has the effect of promoting the activation and proliferation of epidermal regenerative stem cells in the residual viable tissue of superficial full thickness burn wound, and these stem cells play an unique role in spontaneous wound healing of deep burn.
