The pre-mutagen 8-Oxo-2'-deoxyguanosine-5'-triphosphate (8-oxo-dGTP) is formed during normal cellular metabolism and its incorporation into DNA leads to transversion mutations. Human cells possess the hMTH-1 gene encoding the enzyme 8-oxo-dGTPase, which catalyzes the hydrolysis of 8-oxo-dGTP to the corresponding 8-oxo-dGMP, preventing mutations. To(More)
Lipolytic enzymes may play a role in the pathogenesis of acute pancreatitis. Therefore, the effects of a lipase inhibitor, THL (tetrahydrolipstatin), a protease inhibitor, FUT (nafamostat mesilate), and albumin under different conditions in rats were investigated. (a) Isolated pancreatic acini were incubated with pancreatic homogenates and triglycerides or(More)
The new CCK-B/gastrin receptor antagonist PD 136450 is of potential value in treating neurologic and psychiatric disorders. We investigated possible side effects on the rat pancreas using acute and chronic administration schedules. In chronic experiments, four groups of rats were given either PD 136450, the proton pump inhibitor BY 308 (in order to induce(More)
We have recently reported that lipase may play a role in the pathogenesis of acute pancreatitis by its ability to release fatty acids from triglycerides. The aim of this study was to further investigate the effect of lipase and its various digestive products on the integrity of isolated pancreatic rat acini. Pancreatic acini were prepared by collagenase(More)
Schizophrenia is a complex mental disorder caused by an interplay between genetic and environmental factors, including early postnatal stressors. To explore this issue, we use two rat lines, apomorphine-susceptible (APO-SUS) rats that display schizophrenia-relevant features and their phenotypic counterpart, apomorphine-unsusceptible (APO-UNSUS) rats. These(More)
5-Fluorouracil (5-FU) has been claimed to have beneficial effects in human pancreatitis because of its ability to inhibit protein synthesis and secretion. However, the effect of 5-FU has not been studied in the pancreas of animals in more detail and the data in human pancreatitis are mostly derived from uncontrolled studies. Thus, we studied potential(More)
