bjective To investigate the effect of 5% Sodium morrhuate and Pingyangmycin on normal tissue. Methods 4 Minipigs had been used in our study, 5% Sodium morrhuate was injected in pig's upper and lower lips of one side, and Pingyangmycin was injected in the other side. Every two animals were killed after 7 days and 14 days, and routinely historical observation had been made. Results The muscle fiber's wither and disappearance can be seen in all samples in the group of 5% Sodium morrhuate, no tissue necrosis was found; But in Pingyangmycin's group, only the wall of vascular became thickening and the tissues outside vascular are normal. Conclusion 5% Sodium morrhuate must be avoided injecting into normal tissue, it can cause normal tissue damaged; Pingyangmycin is safety to the tissues outside vascular.
