For the patients, I investigated clinical symptoms, gastroduodenoscopy, intake by oral and parenteral route, and output by urine and stool, serum ALP, AST. ALT, Bilirubin, BUN, Creatinine level and urine analysis. On admission day, the LFT level was as follows. The serum mean ALP, AST, ALT, Total Bilirubin and Direct Bilirubin was $10.05{pm}2.75;KAU$, $66.67{pm}9.88;IU／L$, $43.80{pm}7.74;IU／L$, $1.89{pm}1.22;mg／dl$ and $1.10{pm}1.14;mg／dl$ respectively. After that day, administered Gamdutang and checked the mean LFT level regullary. Until the 3rd day, the mean ALP, AST, ALT, Total Bilirubin and Direct Bilirubin level was $11.01{pm}3.16;KAU$, $56.47{pm}7.19;IU／L$, $59.00{pm}7.57;IU／L$, $2.54{pm}1.78;mg／dl$, $1.64{pm}1.59;mg／dl$ respectively. From 4th day to 7th day, the mean ALP; AST, ALT, Total Bilirubin and Direct Bilirubin level was $12.51{pm}3.49;KAU$, $77.85{pm}7.17;IU／L$, $58.00{pm}9.09;IU／L$, $2.54{pm}1.97;mg／dl$, and $1.80{pm}1.81;mg／dl$ respectively. From 8th day to 10th day, the mean ALP, AST, ALT, Total Bilirubin and Direct Bilirubin level was $12.43{pm}3.14;KAU$, $41.13{pm}6.49;IU／L$, $50.40{pm}7.17;IU／L$, $1.66{pm}1.90;mg／dl$ and $1.14{pm}1.50;mg／dl$ respectively. From 11th day to 14th day, the mean ALP, AST, ALT, Total Bilirubin and Direct Bilirubin level was $12.30{pm}3.25;KAU$, $31.07{pm}3.85;IU／L$, $43.33{pm}5.49;IU／L$, $1.62{pm}1.95;mg／dl$, $1.17{pm}1.71;mg／dl$ respectvely. On admission day, the mean RFT level as follows. Serum BUN and Creatinine level was $28.73{pm}5.19;mg／dl$ and $1.82{pm}1.27;mg／dl$ respectively. After that day, administered Gamdutang and checked the mean RFT level regullary. Until the 3rd day, the mean BUN and Creatinine level was $32.12{pm}5.65;mg／dl$ and $2.31{pm}0.45;mg／dl$ respectively. From 4th day to 7th day, the mean BUN and Creatinine level was $31.07{pm}5.47;mg／dl$ and $1.92{pm}0.79;mg／dl$ respectively. From 7th day to 10th day, the mean BUN and Creatinine level was $17.47{pm}3.57;mg／dl$ and $1.33{pm}0.59;mg／dl$ respectively. From 11th day to 14th day, the mean BUN and Creatinine level was $11.93{pm}3.16;mg／dl$, $1.27{pm}0.38;mg／dl$ respectively.
