AIM:To observe the effect of different concentrations Buddleja offcinalis eye drops(BOED)to inflammatory factors of lacrimal gland cells of castrated male rabbit with dry eye.<p>METHODS:Forty-two healthy adult New Zealand rabbits were randomly divided into 7 groups, 6 rabbits each group. Group A: blank group; Group B: model group; Group C: low concentrations BOED group; Group D: medium concentrations BOED; Group E: high concentrations BOED; Group F: the placebo group; Group G: testosterone groups. All rabbits of groups B to G were cut off bilateral testis and epididymis except group A. The rabbits of groups C, D, E and F were dropped relevant eye drops except groups A and B. All rabbits were tested for Schimer I test(SIT)and break-up time(BUT)before operation and 4wk after operation. Expressions of inflammatory factors of TNF-α, IL-1β from lacrimal gland cells were checked in immunohistochemical staining method.<p>RESULTS:1)Comparison of SIT and BUT: Compared with the groups D, E and G, group C had statistical significance(<i>P</i><0.01). Compared with groups D and E, G groups, there was no significant difference among those group after operation(<i>P</i>>0.05); 2)Comparison of inflammatory factors of TNF-α, IL-1β after operation: Compared with value of the average optical density of TNF-α and IL-1β of group C, those of groups D, E and G were obviously different after operation(<i>P</i><0.05). Compared D with E, G groups, there was no significant difference between those group after operation(<i>P</i>>0.05).<p>CONCLUSION: 1)Compared with androgen, BOED has the similar effect of depressing the expression of inflammatory factors. But its effect is slightly weaker than the androgen; 2)The depressing effect of medium and high concentration BOED are better than low concentration. Compared with medium and high concentration of BOED, there was no significant difference between two groups.
