Figure 4. Quantification of mRNA expression of RANTES and MDC in conjunctiva and ciliary bodies by real time-PCR. mRNA expression levels of RANTES and MDC normalized to the levels of the endogenous control, GAPDH, were quantified in the conjunctiva (A) and ciliary bodies (B) of control rats and of rats with EIU 6 h and 24 h after LPS injection using semi-quantitative real-time PCR. Data shown are the mean±SD. An asterisk indicates that there is a significant difference between the control rats and the rats with EIU at 24 h (p<0.05).
