Animal models for CP in rats can be classified into 2 groups: one is noninvasive or nonsurgical models and the other is invasive or surgical models. Pancreatic injury induced by repetitive injections of supramaximal stimulatory dose of caerulein (Cn) or by intraductal infusion of sodium taurocholate (NaTc) recovered within 14 days, whereas that caused by repetitive injection of arginine or by intraductal infusion of oleic acid was persistent. However, the destroyed acinar tissues were replaced by fatty tissues without fibrosis. Transient stasis of pancreatic fluid flow by 0.01% agarose and minimum injury of the pancreatic duct by 0.1% NaTc solution induced progressive pancreatic injury although one alone is insufficient to cause persistent pancreatic injury. However, the damaged tissue was replaced by fatty tissue without fibrosis. Continuous pancreatic ductal hypertension (PDH) caused diffuse interlobular and intralobular fibrosis closely resembling human CP.

Pancreatic Duct Stenting

AbstractPancreaticopleural fistula is a rare complication of chronic pancreatitis caused by disruption of the pancreatic duct and fistulous communication with the pleural cavity. It usually presents with respiratory symptoms from recurrent large volume pleural effusions. Paucity of abdominal symptoms makes it a diagnostic challenge, leading often to delayed diagnosis. Marked elevation of pleural fluid amylase, which is not a commonly performed test, is a sensitive marker in its detection. Imaging with magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography can help delineate the fistula. In this report, we present the clinical features, imaging, and management of a 59-year-old male patient with pancreaticopleural fistula, wherein the diagnosis was suspected only after repeated pleural fluid drainages were performed for re-accumulating pleural effusions and it was eventually successfully treated with pancreatic duct stenting. We review the literature with regards to the incidence, presentation, diagnosis, and management of this rare entity.

The oil contents and fatty acid (FA) compositions of ten new and one wildCamellia oleiferavarieties were investigated. Oil contents in camellia seeds from newC. oleiferavaried with cultivars from 41.92% to 53.30% and were affected by cultivation place. Average oil content (47.83%) of dry seeds from all ten new cultivars was almost the same as that of wild commonC. oleiferaseeds (47.06%). NewC. oleiferacultivars contained similar FA compositions which included palmitic acid (C16:0, PA), palmitoleic acid (C16:1), stearic acid (C18:0, SA), oleic acid (C18:1, OA), linoleic acid (C18:2, LA), linolenic acid (C18:3), eicosenoic acid (C20:1), and tetracosenoic acid (C24:1). Predominant FAs in mature seeds were OA (75.78%~81.39%), LA (4.85%~10.79%), PA (7.68%~10.01%), and SA (1.46%~2.97%) and OA had the least coefficient of variation among different new cultivars. Average ratio of single FA of ten artificialC. oleiferacultivars was consistent with that of wild commonC. oleifera. All cultivars contained the same ratios of saturated FA (SFA) and unsaturated FA (USFA). Oil contents and FA profiles of new cultivars were not significantly affected by breeding and selection.
