The pancreatic lesions in 6- to 36-week-old spontaneously hypertensive rats (SHR), stroke prone SHR (SHRSP) and Wistar-Kyoto rats (WKY) were examined histopathologically. Inflammatory cell infiltration with hemorrhage and stromal fibrosis became evident in 12-week-old SHR and SHRSP together with acinar atrophy and/or degeneration and ductular proliferation. These changes in SHR and SHRSP were even more prominent at the age of 24 weeks and extremely severe at 36 weeks. In addition, in SHR and SHRSP over 12 weeks of age, small necrosis of acinar cells was found occasionally together with fibrosis and arteriosclerosis. Pancreatic arteriosclerosis was marked in SHR and SHRSP over 24 weeks of age at the level of arterioles < 200 microns in diameter. Adrenergic nerve fibers stained by fluorescence histochemistry were present around the pancreatic arteries and ducts and within the parenchyma, and they were denser in SHR and SHRSP than in WKY, indicating hyperinnervation of the sympathetic nervous system in SHR and SHRSP. It is suggested that the pancreatic ischemia caused by arteriosclerosis due to facilitation of the sympathetic nervous system is an important factor in the pathogenesis of the spontaneous pancreatitis of SHR and SHRSP.

Dieticians computed the fat and cholesterol contents of 11 foods that were commercially produced as ready-to-eat food from food component lists and obtained the P/S ratio (polysaturated/saturated fatty acids) from the fatty acid component list. Meanwhile the same foods were diluted and homogenized. The internal standard was combined with hepatadecanoic acid and tricaprin. The samples that had been extracted by the Folch method were analyzed for their lipid content (GC analysis using a HS-SS-10 columns for fatty acids and an OV-1 column for lipid and cholesterol). A significant positive correlation was noted between the results of dieticians' analysis and those obtained from a gas chromatographic analysis of lipid and cholesterol contents and the P/S ratio, proving that lipid analysis of food by dieticians is highly reliable. Therefore for diseases (such as hyperlipemia, arteriosclerosis, obesity, diabetes mellitus, fatty liver, and pancreatitis) in which dietary factors have a significant effect on their clinical course, dietary instructions on dietary fats based on an analysis by dieticians are considered to be effective.

Severe stenosis/occlusion of the proximal celiac trunk due to median arcuate ligament compression (MALC), arteriosclerosis, pancreatitis, tumor invasion, and celiac axis agenesis has been reported. However, clinically significant ischemic bowel disease attributable to celiac axis stenosis/occlusion appears to be rare because the superior mesenteric artery (SMA) provides for rich collateral circulation. In patients with celiac axis stenosis/occlusion, the most important and frequently encountered collateral vessels from the SMA are the pancreaticoduodenal arcades. Patients with celiac artery stenosis/occlusion are treated by interventional radiology (IR) via dilation of the pancreaticoduodenal arcade. In patients with dilation of the pancreaticoduodenal arcade on SMA angiograms, IR through this artery may be successful. Here we provide several tips on surmounting these difficulties in IR including transcatheter arterial chemoembolization for hepatocellular carcinoma, an implantable port system for hepatic arterial infusion chemotherapy to treat metastatic liver tumors, coil embolization of pancreaticoduodenal artery aneurysms, and arterial stimulation test with venous sampling for insulinomas.

The aim of this study was to examine whether the detection of pulmonary fat embolization is valid as a significant indicator of heat exposure in forensic autopsies. In 54 cases where there was no evidence of fracture, burn or pancreatitis, 25 cases (46.3%) showed pulmonary fat embolization, the degree of which was pathohistologically classified as slight in all cases. Among the 25 cases where the pulmonary fat embolization was detected, the individual had died under a high ambient temperature in 14 cases (56%). Based on logistic regression analysis, pulmonary fat embolization was found to be associated with a high ambient temperature, but not associated with coronary arteriosclerosis, fatty infiltration in the liver, severe infectious diseases, intracranial hemorrhage or the detection of methamphetamine in the blood. Further investigations are necessary before these findings can be applied in forensic autopsy cases; however, it is likely that the detection of pulmonary fat embolization is valuable as one of the diagnostic findings indicating antemortem heat exposure.

1. Anatomical lesions of the pancreas occur in more than seven-eighths of all cases of diabetes mellitus. 2. In diabetes associated with lesions of the pancreas, the islands of Langerhans constantly show pathological changes (sclerosis, hyaline degeneration, infiltration with leucocytes and hypertrophy). 3. In some cases of pancreatic diabetes (twelve of ninety cases) the lesion of the pancreas is limited to the islands of Langerhans. 4. In sixteen cases of diabetes associated with hyaline degeneration of the islands of Langerhans the average duration of the disease has been three and a half years; in forty-six cases with sclerosis of these bodies, three years and eleven months. In six cases of diabetes associated with an infiltration of leucocytes about the islands of Langerhans the average duration has been eleven months. 5. Destructive lesions of the islands of Langerhans may be associated with compensatory hypertrophy of other interacinar islands. 6. Peculiar adenoma-like hypertrophy of the islands of Langerhans occurs in a small proportion of cases (seven of ninety) and may be associated with adenomata of the thyroid gland (two cases) and of the pituitary body (one case). 7. Diabetes mellitus occurring in association with haemochromatosis (bronzed diabetes) is referable to pigmentation and destruction of the islands of Langerhans. 8. The pancreas is found to exhibit no pathological changes in twelve per cent. of cases. In approximately one-half of these cases it has been noted that the size of the gland or the number of islands is much less than normal. 9. Fifty per cent. of cases of diabetes mellitus occurring before the age of thirty years are associated with lesions of the pancreas; seventy-five per cent. of all cases of diabetes in which the pancreas is normal occur before the age of thirty years. Ninety-seven per cent. of cases of diabetes occurring after the age of thirty years are associated with lesions of the pancreas; and eighty-six per cent. occur in association with chronic interacinar pancreatitis accompanying arteriosclerosis. 10. Interacinar pancreatitis which occurs in seventy-three per cent. of all cases of diabetes is almost constantly associated with arteriosclerosis: gangrene of the extremities, which occurs with one-fourth of all cases of interacinar pancreatitis, is doubtless referable to the same cause. 11. Chronic interlobular pancreatitis, when associated with diabetes, is accompanied by sclerosis or hyaline degeneration of the islands of Langerhans. 12. Diabetes in association with myxoedema or with exophthalmic goiter may be referable to a lesion of the pancreas, namely, chronic interacinar inflammation with sclerosis of the islands of Langerhans; diabetes in association with acromegaly may be referable to a lesion of the islands of Langerhans, namely, sclerosis and hyaline degeneration with adenoma-like hypertrophy.

Clinicopathologic characteristics of paraduodenal (groove) pancreatitis (PDP) remain to be fully unraveled. In this study, 47 PDPs with preoperative enhanced images available were subjected to detailed comparative analysis in conjunction with pathologic findings. PDP were predominantly in males (3:1) with a mean age of 50 years, and 60% had a preoperative diagnosis of cancer. Mean lesional size was 3.1 cm. Three distinct subtypes were identified by imaging. Solid-tumoral (type-1) with groove-predominant (type-1A, 36%) forming a distinct solid band between the duodenum and pancreas often with histologic microabscesses (69% vs. 33% in others), and pancreas-involving (type-1B, 19%) forming a pseudotumoral mass spanning into the head-groove area, always diagnosed preoperatively as "cancer," but often lacked parenchymal atrophy of the body (44% vs. 92%). Cyst-forming (type-2) had groove-predominant (type-2A, 15%), often accompanied by Brunner gland hyperplasia, and pancreas-predominant (type-2B, 15%) were in younger (mean: 44 y) females (57% vs. 18%) and had less alcohol/tobacco abuse (50/33% vs. 81/69%). Ill-defined (type-3; 15%) often had main pancreatic duct dilatation (mean: 5.6 vs. 2.8 mm). The capricious presentations of PDP could be attributed to variable effects of different mechanistic and precipitative etiopathogenetic factors such as disturbed accessory duct outflow (dilated Santorini duct, 87%), aggravated by alcohol (77%) with superimposed stasis in the main ampulla (previous cholecystectomy, 47%; choledocholithiasis, 9%), strictured Wirsung duct (68%), and some likely exacerbated by ischemia (hypertension [59%], tobacco abuse [64%], arteriosclerosis in the tissue [23%]). In conclusion, our study identified 3 distinct types of PDP and each may reflect different pathogenetic contributing factors.

Inflammation is the vital defensive response triggered by our immune system against an infection or deleterious stimuli. This response in due course affects its own biological system leading to serious diseases like arteriosclerosis, osteoporosis, pancreatitis, cancer etc. Currently, researchers focused on utilizing phytochemicals as anti-inflammatory drugs since the drugs presently available in the market causes serious side effects and are less potent. Flavonoids are polyphenols which imparts colours to the plants and fruits. These flavonoids serve as phytonutrients to plants and they also possess antioxidant, anti-inflammatory and anti-cancer properties. Naringenin is one such flavonoid classified under flavones groups present in citrus fruits and vegetables. The present study is aimed to identify and confirm the antinociceptive and anti-inflammatory efficacy of Naringenin in different mice models. The antinociceptive effect of Naringenin was analyzed by both thermal induced and chemical induced nociceptive mice models. Carrageenan-induced paw edema test was performed to detect the anti-inflammatory effect of Naringenin and it is confirmed by analyzing the leukocyte infiltration in peritoneal cavity. Air pouch model test is performed to estimate the inhibitory property of Naringenin against proinflammatory cytokines. The potency of drug Naringenin was confirmed by treating along with opioid inhibitors naloxone and the results compared with standard drugs. To assess the muscle relaxant property of Naringenin open field test was performed. The overall results of Naringenin in different nociceptive and inflammatory mice models suggest that, Naringenin is a potent anti-inflammatory drug which relieves pain effectively and can be used in pain management therapy.
