dc.description.abstract아스코르빈산은 상처조직형성에 중요한 역할을 하는 procollagen hydroxylation에 작용하

는 조효소로 알려져 있으나 고농도에서는 결막하 섬유아세포에 독성을 나타낸다고 보고되어

있다. 이에 본 저자는 아스코르빈산이 사람과 가토에 테논낭 섬유아세포의 증식에 미치는

영향을 알아보고자 시간과 용량에 따른 효과를 비교하였다.

사람과 가토의 테논낭 섬유아세포를 각각 배양하였고 아스코르빈산을 0.75mM, 1.00mM,

1.25mM, 1.50mM, 2.00mM로 각각 농도를 달리하여 24시간 노출시킨 후 1일, 2일, 5일째에

hemacytometer를 이용하여 섬유아세포 수를 측정하여 억제정도를 평가하였다.

아스코르빈산이 테논낭 섬유아세포의 증식을 억제하는 농도는(ID〈sub〉50〈/sub〉) 사람

에서는 1일째, 2일째, 5일째 각각 1.14mM, 1.53mM, 1.72mM이었고, 가토에서는 각각

1.59mM, 1.16mM, 1.54mM로 나타났고 사람에서는 1일째, 가토에서는 2일째 농도가 각각 사

람과 토끼의 방수속에 함유되어 있는 아스코르빈산의 농도와 유사하였다.

본 연구에서는, 아스코르빈산이 사람에서는 1.14mM 이상에서, 가토에서는 1.16mM 이상

-Abstract-

Although ascorbic acids have been known to play a role in the hydroxylation of

procollagen in collagen synthesis, it can also inhibit the proliferation of fibroblasts at

high concentration.

The time- and dose-related effects of ascorbic acids in proliferation of human and

rabbit Tenon's fibroblasts were studied. Fibroblasts were incubated in different

concentrations of ascorbic acid at 0.75mM, 1.00mM, 1.25mM, 1.50mM, and 2.00mM and

evaluated on days 1, 2 and 5 after exposure to ascorbic acid for 24 hours. To evaluate

the effects of different concentration of ascorbic acids on fibroblast proliferation, cell

density was quantified by hemacytometer.

In conclusion, ascorbic acid was a potent inhibitor of fibroblast proliferation, the

effective concentration of ascorbic acid were(average ID〈sub〉50〈/sub〉) 1.14, 1.53,

1.72mM in human fibroblast, and 1.59, 1.16, 1.54mM in rabbit on days 1, 2, and 5. The

effective concentration of ascorbic acid in humans was similar to the normal human

concentration of ascorbic acid in aqueous humor on day 1, and the concentration of

ascorbic acid in rabbits was similar to the normal rabbit aqueous humor on day 2.

This study shows that ascorbic acid inhibits cell proliferation in concentration of

1.14mM or more in humans and 1.16mM or more in rabbits, future clinical studies may

show that these agents reduce bleb failure following glaucoma filtration surgery.
