BACKGROUND & AIMS Pancreatic stellate cells have some similarities to hepatic stellate cells and an intrinsic renin-angiotensin system is present in the pancreas and is enhanced in acute pancreatitis and chronic pancreatic hypoxia. We assessed the effects of lisinopril, an angiotensin-converting enzyme (ACE) inhibitor, on spontaneously occurring chronic(More)
Intramural injection of peptidoglycan-polysaccharide polymers into the distal colon in rats induces granulomatous colitis associated with extracolonic manifestations. We sought to clarify the effects of Kupffer-cell depletion induced by the intravenous administration of gadolinium on colonic and extracolonic inflammation in this model. The effects of(More)
Angiotensin-converting enzyme inhibitors and angiotensin receptor antagonists attenuate fibrosis in the kidney, heart, and liver by suppressing transforming growth factor-beta1 mRNA and decreasing production of extracellular matrix proteins. We recently demonstrated that lisinopril, an angiotensin-converting enzyme inhibitor, alleviates pancreatic(More)
Goblet cell carcinoid of the appendix is a rare neoplasm and clinically tends to take a malignant course. Most cases are young and early stage, and the surgical strategy is available. But appropriate chemotherapy for inoperable cases with peritoneal dissemination is not established. A 77-year-old woman with a past history of appendectomy was admitted to our(More)
We recently demonstrated that both lisinopril and candesartan, an angiotensin-converting enzyme inhibitor and angiotensin II type 1 receptor blocker, respectively, attenuate pancreatic inflammation and fibrosis in male Wistar Bonn/Kobori (WBN/Kob) rats. The purpose of the present study was to assess whether combination therapy with low doses of both,(More)
We presented the case of a 46-year-old man with no medical or family history but with a history of smoking 3 packs of cigarettes per day for the past 25 years. He was admitted to our hospital due to hemoptysis. Chest computed tomography revealed a tumor of right upper lung and interstitial pneumonia in the surrounding lung parenchyma. He was operated upon(More)
The serological risk prediction system combines the pepsinogen test and anti-Helicobacter pylori (H. pylori) antibody determination. In this system, chronic atrophic gastritis (CAG) is diagnosed using the pepsinogen test. Patients who are H. pylori negative and pepsinogen negative are classified into group A, are assumed to be H. pylori uninfected, and are(More)

Biomarkers predicting the response to the anticancer treatment and prognosis in patients with advanced hepatocellular carcinoma (HCC) are required. Recently, high mobility group box 1 (HMGB1) was reported to promote HCC progression and be associated with poor prognosis for patients with HCC. The purpose of this study was to assess serum HMGB1 concentrations(More)
