The Experimental Study on Anti-bacterial Potency of Various Herbal Eye drops on Staphylococcus aureus induced keratitis
Abstract
Objectives : This experimental study was performed to investigate the effect of herbal eye drops(Sean-tang, Jinpi-san, Tangpo-san, Copitdis Rhizoma) on Staphylococcus aureus keratitis. Methods : After administering various herbal eye drops on Staphylococcus aureus, I measured MIC and the size of inhibition zone. MIC was measured by dropping from 20 to 50㎕ according to density. Anti-bacterial potency was measured by the size of inhibition zone with change of volume under2days culture condition. Also continuous anti-bacterial potency of herbal eye drops was measured by the size of inhibition zone according to 2 days and 6 days culture each under the 50㎕condition. Results : 1. MIC on Staphylococcus aureus in Sean-tang, Jinpi-san and Tangpo-san was 100%, 20㎕. 2. MIC on Staphylococcus aureus in Coptidis rhizoma was 10%, 30㎕. 3. MIC on Staphylococcus aureus in Cravit was 0.1%, 50㎕. 4. Under the 2 days culture condition, the size of inhibition zone on Staphylococcus aureus by volume for Sean-tang was 12.0mm in 50㎕, Jinpi-san was 19.0mm in 50㎕, Tangpo-san was 15.0mm in 50㎕, Coptidis rhizoma was 32.7 mm in 50㎕and Cravit was 31mm in 50㎕, Coptidis rhizoma showed the highest anti-bacterial potency. 5. Under the 50㎕condition, the size of inhibition zone on Staphylococcus aureus by 2 and 6 culture days for Sean-tang was 12.0mm, Jinpi-san was 19.0mm, Tangpo-san was 15.0mm, Coptidis rhizoma was 32.7mm and Cravit was 31.0 mm, which showed sameness anti-bacterial potency in 2 days and 6 days. Conclusions : The present author think that the herbal eye drops can be used to cure Staphylococcus aureus keratitis and if further study is performed, the use of the herbal eye drops will be valuable and beneficial in the clinical medicines.
