Serum immunoreactive trypsin (IRT) determination has been recommended as a screening test in chronic pancreatitis. Using a commercial radioimmunoassay kit (RIA--gnost Trypsin; Behring-Werke, Marburg/Lahn, FRG) the interassay coefficient of variation was 26--44% for three different test sera. Gel filtration chromatography profiles revealed immunoreactivity in the position of 125I-trypsin and (less than 50%) in the void volume. The test was evaluated in controls (n = 90), chronic relapsing pancreatitis (CRP;n = 60) and after total pancreatectomy (n = 5). In 65% of the CRP cases decreased IRT values were found, whereas during acute attacks of CRP supranormal and normal values were found. After total pancreatectomy IRT levels were undetectable. It is concluded that the sensitivity of this IRT test is limited and that the available test system needs improvement.

The aim of this study was to test the hypothesis that apoptosis can protect against experimental pancreatitis and induction of apoptosis by an extract of Artemisia asiatica (DA-9601) is beneficial in cerulein-induced pancreatis in rats. Pancreatitis was induced in 6-week-old male SPF Sprague-Dawley rats by two intravenous (i.v.) administrations of 40 microg/kg cerulein. To investigate the effects of DA-9601 on the severity of pancreatitis and extent of apoptosis, rats were treated with intragastric DA-9601, 30 mg/kg (D30), 100 mg/kg (D100), or 300 mg/kg (D300), intraperitoneal superoxide dismutase, 10,000 U/kg (SOD), and i.v. gabexate mesilate, 40 mg/kg (Foy), three times (30 min before cerulein injection, 30 and 90 min after cerulein injection). The control group was administered vehicle alone. Ten rats were included in each treatment group and control group. Rats were sacrificed 5 h after cerulein treatment. Serum amylase, histological activity index (HAI), pancreatic lipid peroxide levels, and apoptotic index [in situ hybridization by terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end-labeling (TUNEL)] were determined. Gel electrophoresis was performed for the presence of DNA fragmentations. The results were as follows. Serum amylase was significantly increased in all cerulein-treated groups compared to normal controls (p < 0.001). The HAI was significantly decreased in only the D300 group compared to the controls (p < 0.05). The apoptotic index of the cerulein-alone group was 3.8 +/- 2.7, but the mean apoptotic indexes of the SOD and Foy groups were 16.4 +/- 4.6 and 13.3 +/- 1.8, respectively, a significant increase (p < 0.01). The apoptotic index was more significantly increased in the DA-9601-treated groups, dose dependently (8.4 +/- 3.4 in D30, 14.8 +/- 4.3 in D100, 24.2 +/- 4.7 in D300). A smearing pattern of DNA electrophoresis was noted in the DA-9601-treated groups. In conclusion, DA-9601, an extract of Artemisia, induced apoptosis of pancreatic acinar cells dose dependently and concomitantly attenuated the severity of pancreatitis.
