The color of the solids and aqueous solutions of 1 and 2 did not change for more than 1 month under air without any shields. The light stability of these two silver(I) complexes is much higher than that of silver(I) methioninate {[Ag(2)(D-met)(L-met)]}(n) (3) (Hmet = methionine), silver(I) S-methyl-L-cysteinate {[Ag(L-mecys)]}(n) (4), and silver(I) L-cysteinate {[Ag(L-Hcys)]}(n) (5).

Although right ventricular involvement is not uncommon, the correct diagnosis is often difficult by echocardiography. In this report, we describe a patient with INVM in whom magnetic resonance imaging was useful to detect right ventricular morphological and functional abnormalities.

At the treatment of bile duct stones using EST, we sometimes experienced the difficult cases, even if the stones were small. For these cases, we tried endoscopic papillary balloon dilatation, and as a result knoches were made. And after the disappearance of the knoch, we could easily remove the stone.

The post operative course was complicated by perforation of the right ventricular free wall by the ICD lead. The type of the active fixation transvenous ICD lead and the type of background cardiac disease are thought to be major risk factors for perforation.

Methods And Results: One hundred and seven patients with SSS were divided into BND (n=30) and N-BND groups (n=77). Sinus cycle length, sinus node recovery time (SRT), sino-atrial conduction time (SACT), the number of isolated sinus node electrograms, atrio-His (AH) interval, His-ventricular (HV) interval, intra-atrial conduction time (PA intervals) and QRS width were measured.
Background: Recent studies have shown that inosine, a purine nucleoside produced during the breakdown of adenosine, has immunomodulatory and anti-inflammatory properties. The aim of this study was to examine the effects of inosine on the course of acute pancreatitis.
Methods: Edematous pancreatitis was induced by the intraperitoneal injection of caerulein (50 micro g/kg), seven times, at 1-h intervals, in male Wistar rats (caerulein pancreatitis).

Background & Aims: Macrophage migration inhibitory factor (MIF), originally described as an inhibitor of the random migration of macrophages, has been shown recently to be involved in the pathogenesis of several inflammatory diseases such as sepsis. The aim of this study was to clarify the role of MIF in acute pancreatitis (AP).
Methods: Hemorrhagic necrotizing pancreatitis and edematous pancreatitis were induced by the injection of taurocholic acid (TCA pancreatitis) and cerulein (cerulein pancreatitis), respectively, on male Wistar rats.
Activated pancreatic stellate cells (PSCs) have recently been implicated in the pathogenesis of pancreatic fibrosis and inflammation. Primary PSCs can be subcultured only several times because of their limited growth potential. A continuous cell line would be valuable in studying molecular mechanisms of these pancreatic disorders.
