Background: 3-Hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) effectively reduce serum levels of low-density lipoprotein (LDL) and total cholesterol. High-intensity statins are recommended for all patients aged ${\leq}75$ with clinical atherosclerotic cardiovascular disease (ASCVD), diabetes mellitus aged 40-75 with ${\geq}7.5%$ estimated 10-year ASCVD risk and LDL-C ${\geq}190mg/dL$. High-intensity statins associated with more frequent adverse events (AEs) compared to moderate- to low-intensity statins. The aim of this study was to compare AEs between high-intensity and moderate- to low-intensity statin group using the Korea Adverse Event Reporting System (KAERS) database. Methods: Adults (${\geq}18years$) with statin-associated AEs from July 2009-June 2014 were included. Only AEs classified as "certain", "probable" and "possible" based on the WHO-Uppsala Monitoring Center criteria were analyzed. Results: In total, 247 AEs from 196 patients [high-intensity statin group (HG), n = 25 (13%); moderate- to low-intensity statin group (MLG), n = 171 (87%)] were included. Mean age was higher in HG compared with MLG ($67{\pm}14$ vs $62{\pm}12$). The HG showed a significant higher frequency of liver/biliary system disorders (37% vs 14%, p = 0.001). Hepatic function abnormal was reported more frequently in HG compared to MLG (26% vs 9%, p = 0.006). Conclusion: According to KAERS data, liver/biliary system disorders were more frequently reported in HG compared to MLG.

Hepatic coccidiosis was occurred in a rabbit farm in Chonbuk province. Clinically, rabbits showed anorexia, diarrhea, dehydration, and depression, subsequently died 3 - 5 days after onset of clinical signs. Grossly, multifocal white spots or lines on the liver suface were observed. Histopathologic lesions included hyperplasia of bile duct epithelium with infiltration of inflammatory cells such as plasma cells and granulocytes, which represents chronic pericholangitis. Different developmental stages of Eimeria stiedae were observed inside the epithelium of biliary system. This is the case of hepatic coccidiosis in rabbits.

Purpose: Biliary atresia (BA) is a disease that manifests as jaundice after birth and leads to progressive destruction of the ductal system in the liver. The aim of this study was to investigate histopathological changes and immunohistochemically examine the expression of glial cell line-derived neurotrophic factor (GDNF), synaptophysin, and S-100 protein in the gallbladder of BA patients. Methods: The study included a BA group of 29 patients and a control group of 41 children with cholecystectomy. Gallbladder tissue removed during surgery was obtained and examined immunohistochemically and histopathologically. Tissue samples of both groups were immunohistochemically assessed in terms of GDNF, S-100 protein, and synaptophysin expression. Expression was classified as present or absent. Inflammatory activity assessment with hematoxylin and eosin staining and fibrosis assessment with Masson's trichrome staining were performed for tissue sample sections of both groups. Results: Ganglion cells were not present in gallbladder tissue samples of the BA group. Immunohistochemically, GDNF, synaptophysin, and S-100 expression was not detected in the BA group. Histopathological examination revealed more frequent fibrosis and slightly higher inflammatory activity in the BA than in the control group. Conclusion: We speculate that GDNF expression will no longer continue in this region, when the damage caused by inflammation of the extrahepatic bile ducts reaches a critical threshold. The study's findings may represent a missing link in the chain of events forming the etiology of BA and may be helpful in its diagnosis.

Hemorrhage into the biliary system as a consequence of injury to the liver has been called "traumatic hemobilia," a term introduced by Sandblom in 1948. The source of gastrointestinal hemorrhage has been frequently misinterpreted, resulting in inadequate or inappropriate treatment, often with catastrophic results and needless fatalities. It is now being diagnosed with increasing frequency, due to more widespread knowledge of the syndrome and improved diagnostic means. we experienced 2 cases of hemobilia following blunt chest trauma, One patient had! multiple rib fractures on right chest by car traffic accident and 13 days later, suddenly massive melena was developed with nausea, vomiting, jaundice and severe pain on right upper quadrant. And so, he had operated on the ligation of Rt. hepatic artery and partial right hepatectomy for a traumatic hemobilia. The other one also revealed similar symptoms 20 days later following blunt chest injury by falling down accident. However, uneventful recovery was seen without any of surgical intervention in this case.

A nine-year-old spayed female Turkish angora cat presented for evaluation of anorexia, lethargy, vomiting, ptyalism and jaundice. Based on clinical examinations including laboratory examinations, concurrent inflammatory condition of the biliary system, pancreas and intestines (triaditis) was suspected. The cat was under antibiotic and immune-suppressive therapy, but there was no response. Further examination revealed the possibility of malignant hepatobiliary tumor with pulmonary metastasis. The condition of the cat continued to deteriorate and the cat died 3 weeks after the diagnosis. This case demonstrates the clinical findings of triaditis combined with suspected malignant hepatobiliary tumor.

Recent advances in cholangiopancreatoscopy technology permit image-enhanced endoscopy (IEE) for pancreatobiliary diseases. There are limitations in endoscopy performance and in the study of the clinical role of IEE in bile duct or pancreatic duct diseases. However, currently available IEEs during cholangiopancreatoscopy including traditional dye-aided chromoendoscopy, autofluorescence imaging, narrow-band imaging, and i-Scan have been evaluated and reported previously. Although the clinical role of IEE in pancreatobiliary diseases should be verified in future studies, IEE is a useful promising tool in the evaluation of bile duct or pancreatic duct mucosal lesions.

The aim of this study was to evaluate the safety and efficacy of treatment of mesoglycan. This study was conducted between September 2003 and May 2004. A total of 292 patients with vascular disorders including cerebral infarction were enrolled. The patients were administered with 50-100mg of mesoglycan by an oral route everyday for eight weeks. Subjective physicians' assessments of efficacy had ratings of 'improvement', 'invariability', 'exacerbation' and 'not being able to assess'. An improvement was observed in 241 patients out of 274; 18 patients were rules out. The efficacy rate was influenced statistically significantly by the duration of therapy (p=0.0392) and daily mean drug dose (p<0.0001). The adverse events were reported in 8 patients (9 cases) out of 292 patients: skin/appendages disorders (0.7%), liver/biliary system disorders (0.7%), cardiovascular system disorders (0.7%), neurologic disorders (0.3%). respiratory disorders (0.3%) and gastrointestinal system disorders (0.3%). There showed no serious adverse events. These results indicate that mesoglycan was well tolerated and effective for the prevention of vascular disorders.

No evidence has accumulated that lead compound is an essential component for biological function in animals. Lead is absorbed primarily through the epithelial mucosal cells in duodenum and the absorption can be enhanced by the substances which bind lead and increase its solubility. Iron, zinc and calcium ions, however, decrease the absorption of lead without affecting its solubility, probably by competing for shared absorptive receptors in the intestinal mucosa. Therefore, the absorption of lead is increased in iron deficient animals. Lead shows a strong affinity for ligands such as phosphate, cysteinyl and histidyl side chains of proteins, pterins and porphyrins. Hence lead can act on various active sites of enzymes, inhibiting the enzymes which has functional sulfhydryl groups. lead inhibits the activity of ${\delta}$-aminolevulinic acid dehydratase for the biosynthesis of hemoproteins and cytochrome, which catalyzed the synthesis of monopyrrole prophobilinogen from ${\delta}$-aminolevulinic acid. Accordingly lead decrease hepatic cytochrome p-450 content, resulting an inhibition of the activity of demethylase and hydroxylase in liver. Little informations are available on the effect of lead on digestive system although the catastrophic effects of lead intoxication are well documented. The present study was, therefore, attempted to investigate the effect of lead on pancreaticobiliary secretion in rats. Albino rats of both sexes weighing $170{\sim}230g$ were used for this study. The animals were divided into one control and three treated groups, i.e., control (physiologic saline 1.5ml/kg i.p.), lead acetate $(l0{\mu}mole/kg/day\;i.p.)$, $Pb(Ac)_2$ and EDTA$(each\;10{\mu}mole/kg/day\;i.p.)$, $Pb(Ac)_2$ and $FeSO_4(each\;l0{\mu}mole/kg/day\;hp)$. The pancreatico-biliary juice was collected under urethane anesthesia, and activities of amylase and lipase were determined by employing Sumner's and Cherry and Crandall's methods. The summarized results are follows. 1) In the experiment for acute toxicity of lead acetate, 20% of mortality was observed in rat treated with lead acetate as well as inhibition of the activity of amylase in the juice at the 3 rd day of the treatment. 2) No increases in body weight were observed in rats treated with lead acetate, while in control group the significant increases were observed. However, the body weights of animals were increased in the group lead acetate plus EDTA or $FeSO_4$. 3) Lead acetate decreased significantly the volume of pancreatico-biliary juice whereas additional treatment of EDTA and $FeSO_4$ prevented it. 4) Total activity of amylase was markedly reduced due to lead acetate treatment, but no change was showed following additional treatment with EDTA and $FeSO_4$. 5) No changes in the cholate and lipase output were observed in rats treated with lead acetate as compared with that of control rats. 6) Increase in bilirubin output in rats treated with lead acetate was shown on the 2nd and 3rd weeks treatment. 7) In the case of in vitro experiment, lead acetate also markedly inhibited release of amylase from pancreatic fragment. 8) Histologic finding indicated that acini vacuolation was induced in the pancreatic tissue of rat treated with lead acete. From the above results, it might be concluded that lead acetate decreases the volume of pancreatico-biliary secretion and inhibits the amylase activity, by acting directly on pancreatic cells.
