Objective A HPLC method was established for determination of the content of ATST in the aqueous humor of rabbits. MethodsThe mobile phase was consisting of methanol-1％ triethylamine(57:43) and omeprazole (OMZ) as internal standard. The detection was carried out with an ultraviolet detector operated at 235nm. ResultsThere was linearity over the range of 2. 056～41.12 ug/ml in the humor aquosus, r=0.9997. The average recovery of ATST was 94.58 ％. Intra-day and in- ter-day RSD were less than 5 ％ and 10 ％ ( n = 5), respectively. Conclusion The method is reliable. It can be used for the study on the pharmacokinetics of ATST.

AIM:To observe the effect of fresh amniotic membrane transplantation ( FAMT) in acute ocular chemical burns.
●METHODS:A prospective study of 25 consecutive cases (36 eyes) with acute ocular chemical burns were treated with FAMT. The clinical efficacy was observed such as the time of amniotic membrane absorbed, corneal epithelialization & transparency, visual acuities and complications.
●RESULTS: With follow-up ranged from 3 to 6mo, 31 eyes′ amniotic membrane were dissolved in 2wk (86%). A total of 33 eyes showed corneal epithelialization in 4wk ( 92%) , 3 eyes showed persistent corneal epithelial defects and need secondary limbal stem cell transplantation or corneal transplantation ( 8%) . A total of 10 eyes showed superficial corneal vascularization (28%), 6 eyes′ cornea were opacity in part (17%), and one eye was symblepharon (3%).
●CONCLUSION:Early FAMT is an effective treatment in the management of acute ocular chemical burns to support epithelial healing, restore ocular surface integrity with potential to improve vision and reduce the incidence of complications. Furthermore, FAMT has advantages of easily obtain and convenient usage, which is suitable in local hospital of our country.
