Study on the Healing-promoting Effect of Total Tanshinone on Sore and Ulcer of Model Rats / 中国药房

ABSTRACT

OBJECTIVE:To investigate the healing-promoting effect of total tanshinone on sore and ulcer of model rats. METH-ODS:Staphylococcus aureus levitation liquid was made to reproduce model rats with sore and ulcer,sc. 50 rats were randomly di-vided into normal group(equal volume of CMC-Na solution),model group(equal volume of CMC-Na solution),ampicillin group (positive drug 20 mg/kg)and total tanshinone high and low dose groups(200 and 100 mg/kg),ig,once a day for continuous 12 d. The general conditions were observed. The content of lysozyme(LZM)and immunoglobulins G(IgG)in serum were tested af-ter 12 d;the content of LZM and IgG in purulent secretion of model rats were respectively tested after dosing of 4 d,8 d and 12 d. The integral of wound deterioration were evaluated. RESULTS:Compared with normal control group,the index was worse in model group. Compared with model group,the appetite and activity amount of total tanshinone in high dose group (200 and 100 mg/kg)were increased,with no secretion on the wound and a clean escharosis;content of LZM and IgG in serum of rats in in to-tal tanshinone high and low dose group were increased after 12 d;also,the content of LZM and IgG in purulent secretion of rats in total tanshinone high and low dose groups were increased after dosing of 4 d,8 d,and 12 d;the integral of wound deterioration in total tanshinone high dose group were decreased after dosing of 8 d and 12 d,with significant difference (P<0.01 or P<0.05). CONCLUSIONS:Total tanshinone can promote the wound healing on sore and ulcer of model rats by a mechanism that is related to the content of LZM and IgG in serum and purulent secretion.
