Background/Aims: The clinical usefulness of urinary trypsinogen-2 dipstick test is still in controversy. We evaluated the usefulness of urinary trypsinogen-2 dipstick test in patients with acute pancreatitis. Methods: Urinary trypsinogen-2 dipstick test was prospectively performed in 50 patients with acute pancreatitis, 50 patients with non-pancreatic abdominal pain, and 50 healthy controls. Results: On admission, urinary trypsinogen-2 dipstick test was positive in 36 of 50 patients with acute pancreatitis (sensitivity, 72%) and in 4 of 50 patients with non-pancreatic abdominal pain (specificity, 92%). On the other hand, it was all negative in controls. The sensitivity and specificity of serum lipase were 78% and 94%, respectively. At 24 hours after admission, the positive rate of urinary trypsinogen-2 dipstick test rose from 72% to 94% (p=0.02). The results of urinary trypsinogen-2 dipstick test was positive in 14 of 15 patients with severe pancreatitis and 22 of 35 patients with mild pancreatitis according to the criteria by Atlanta International Symposium, 1992. Conclusions: Urinary trypsinogen-2 dipstick test is comparable to serum lipase in diagnosing acute pancreatitis. Delayed measurement and severe pancreatitis are more likely to yield positive results with urinary trypsinogen-2 dipstick test. Thus, we suggest that the cut-off value of urinary trypsinogen-2 dipstick test should be lowered to increase its sensitivity. (Korean J Gastro-enterol 2004;43:364-369)

Objective : Hongyi (Formica yessensis) is the dried insect of fomicidae. In previous studies, it appeared possibilities on anti-thrombosis, preventing atherosclerosis, treating rheumatoid disease, and inhibiting hela cell. In this study, we investigated anti-inflammatory effects and mechanism of Hongyi. Methods : Hongyi A was extracted by water and made dried powder. Hongyi B was extracted by ethanol and made dried powder. We measured Nitric Oxide (NO) production on the mouse macrophages (RAW 264.7), mouse vascular endothelial cell (MOVAS) and human vascular endothelial cell (HUVEC) for anti-inflammatory effect. In addition, we conducted reverse transcription reaction (RT-PCR) for investigating the mechanism. Results : In RAW 264.7 macrophages stimulated by LPS, Hongyi A (100 ㎍/㎖) decreased NO production compared with LPS 2 ㎍/ml control group with statistical significance (p<0.05). Hongyi A (50, 100 ㎍/㎖) also decreased NO production compared with LPS 4 ㎍/ml control group with statistical significance (p<0.01). Hongyi B (50, 100 ㎍/㎖) decreased NO production compared with LPS 2 ㎍/ml control group with statistical significance (p<0.01). Hongyi B (10, 50, 100 ㎍/㎖) also decreased NO production compared with LPS 4 ㎍/ml control group with statistical significance (p<0.01, p<0.001, p<0.001). In the MOVAS, Hongyi A and B increased NO production compared with control group. In the HUVEC, Hongyi B increased NO production compared with control group. The expression of NF-κB in 12-hours MOVAS culture was decreased by Hongyi A and B (10, 50 ㎍/ml) compared with control group, but expression of IκB was increased. In the 24-hours MOVAS culture, expression of IκB was significantly increased. The expression of NF-κB in 12 hours HUVEC culture was decreased by Hongyi A and B compared with control group, but expression of IκB was increased. Hongyi B also increased eNOS mRNA gene expression. Conclusions : Hongyi A and B showed anti-inflammatory effect in mouse macrophages with the activation of vascular endothelial cell through NO production in MOVAS and HUVEC repectively. Honyi B showed superior effect than Hongyi A, but additonal mechanism study should be conducted.

목적: 본 교실에서는 건강 자원자에서 phosphodiesterase (PDE) 5형 억제제인 sildenafil이 전체 위 배출능에는 영향이 없었으나 음식물의 위내 분포에는 영향이 있음을 보고한 적이 있다. 이에 sildenafil 보다 작용시간이 긴 것으로 알려진 tadalafil (cialis(R))은 위 배출에 어떠한 영향을 미치는지 알아보고자 하였다. 대상 및 방법: 건강한 남자 자원자 8명(평균 나이 26.4세)을 대상으로 투약 전, tadalafil 투약 30분 후, 투약 24시간 후에 위 배출 주사를 시행하여 전체 위 배출능을 알아보기 위한 지표로서 total T(1/2) (min)을 구하였고, 위내 분포를 알아보기 위한 지표 중 위 근위부에 대해서는 proximal T(1/2) (min)과 검사식 섭취 직후 위 근위부의 방사선량인 initial proximal activity (%)를, 위 원위부에 대해서는 위 원위부에서 가장 높이 기록된 방사선량인 maximal distal content (%)을 구한 다음 tadalafil 효과 및 24시간 후까지 작용 지속 여부를 확인하였다. 결과: 위 배출 주사 결과 투약 전, tadalafil 투약 30분 후, 투약 24시간 후의 total T(1/2) (min), proximal T(1/2) (min), initial proximal activity (%), maximal distal content (%)가 모두 통계학적으로 유의한 차이를 보이지 않았다. 결론: 최근 시판된 PDE 5형 억제제, tadalafil은 위 배출 및 위내 분포에 유의한 영향을 미치지 않음을 확인할 수 있었다. Background/Aims: In a previous study we demonstrated an influence of sildenafil, a phosphodiesterase (PDE) type 5 inhibitor, on intragastric food maldistribution without affecting total gastric emptying. In this we wanted to determine the effect of tadalafil (cialis(R)), which has longer duration of action than sildenafil, on gastric emptying. Methods: Eight male (mean age, 26.4 yrs) healthy volunteers were selected. Total T(1/2) (min) was measured to assess total gastric emptying before, 30 minutes and 24 hours after tadalafil intake. Proximal T(1/2) (min), initial proximal activity (%)-radioactiviy measured in the proximal body of the stomach immediately after food ingestion-, and the maximal distal content (%)-the highest radioactiviy measured in the distal body of the stomach was measured as indicators of intragastric food distribution. Results: There were no significant differences in total T(1/2) (min), proximal T(1/2) (min), initial proximal activity (%) and maximal distal content (%) before and 30 minutes and 24 hrs after intake of tadalafil. Conclusions: The recently launched PDE5 inhibitor, tadalafil, has no significant influence on total gastric emptying or intragastric food distribution. (Kor J Neurogastroenterol Motil 2006;12:31-34)
