Results Acute oral LD50 were 278 mg/kg and 56.2 mg/kg in rats and mice respectively, while dermal LD50＞2 000 mg/kg and inhalative LC50＞3 000 mg/m3. Skin and eye irritancy were estimated to be negative and mild respectively. Cumulative coefficient was 2.3 and allergic rate was 0%. A negative result was observed in Ames assay while increased frequencies of bone marrow micronuclei and spermatocyte chromosome aberrations were noted in the high dose (11.24 mg/kg) group.

Epidermal cells near the wound dedifferentiate and proliferate forming blastema and/or migrate to the wound plane forming a pre-epidermis consisting of several layers of stem cells covering the wound plane, which then re-differentiates further forming fully developed epidermis. Cells in the parietal peritoneum are also induced by injury to dedifferentiate into stem cells which then proliferate and migrate along the parietal peritoneum to the wound place forming a pre-peritoneum which re-differentiates into fully developed parietal peritoneum.
