Complications of penile prosthesis include malfunction, infection and patient dissatisfaction. Herein, a rare complication of a retained reservoir having eroded into the bladder after the removal of the penile components of a three-piece penile prosthesis, is reported. A 39-year-old man complained of irritative voiding symptoms. The symptoms had developed 4 years after the removal of the penile components of the prosthesis. The erosion of the reservoir into the bladder was discovered incidentally during the treatment of bladder calculi. The reservoir was removed by an open vesicolithotomy.

Duodenal diverticulum usually originates in the second portion of the duodenum and occasionally causes duodenal obstruction, hemorrhage, perforation and diverticulitis. A bleeding from Dieulafoy's lesion in a duodenal diverticulum is rare. It is not easily dignosed and treated by forward viewing endoscopy. Recently, a case was reported describing the hemorrhage from the Dieulafoy's lesion in a duodenal diverticulum which was treated by hemoclip with forward viewing endoscopy. Hemoclip application is considered to be the most appropriate endoscopic treatment, because sclerotherapy, electrocoagulation or band ligation for Dieulafoy's lesion in the duodenal diverticulum may increase risk of duodenal perforation. We report a case of duodenal perforation due to hemoclip application for the treatment of Dieulafoy's lesion in a duodenal diverticulum.

Hemobilia is a disease caused by injury or conditions that cause the abnormal communication between intrahepatic blood vessels and biliary tract, resulting in leakage of blood into the biliary tract. In the past, trauma had been the most common cause of hemobilia. However, with the increasing invasive procedures in the hepatobiliary tract, iatrogenic origin has become the major cause of hemobilia. Also, non-traumatic etiologies of hemobilia include vascular malformation such as aneurysm, gallstone, inflammation, biliary tumor, hepatocellular carcinoma and coagulopathy. Among these non-traumatic etiologies, choledocholithiasis is a rare cause of hemobilia. The authors have experienced two cases of hemobilia caused by choledocholithiasis, which was diagnosed by abdominal ultrasonography, abdominal CT and duodenoscopy. Both patients were treated by the endoscopic sphincterotomy and stone removal with basket.

This study investigated the protective effects of diallyl disulfide (DADS) against acetaminophen (AAP)-induced acute renal injury in male rats. We also investigated the effects of DADS on kidney injury molecule-1 (KIM-1) and neutrophil gelatinase-associated lipocalin (NGAL), which are novel biomarkers of nephrotoxicity in renal tissues, in response to AAP treatment. The following four experimental groups were evaluated: (1) vehicle control, (2) AAP (1,000 mg/kg), (3) AAP&DADS, and (4) DADS (50 mg/kg/day). AAP treatment caused acute kidney injury evidenced by increased serum blood urea nitrogen (BUN) levels and histopathological alterations. Additionally, Western blot and immunohistochemistry analysis showed increased expression of KIM-1 and NGAL proteins in renal tissues of AAP-treated rats. In contrast, DADS pretreatment significantly attenuated the AAP-induced nephrotoxic effects, including serum BUN level and expression of KIM-1 and NGAL proteins. Histopathological studies confirmed the renoprotective effect of DADS. The results suggest that DADS prevents AAP-induced acute nephrotoxicity, and that KIM-1 and NGAL may be useful biomarkers for the detection and monitoring of acute kidney injury associated with AAP exposure.

In this study, the potential hepatotoxicity of 1,3-dichloro-2-propanol and its hepatotoxic mechanisms in rats was investigated. The test chemical was administered orally to male rats at 0, 27.5, 55, and 110 mg/kg body weight. 1,3-Dichloro-2-propanol administration caused acute hepatotoxicity, as evidenced by an increase in serum aminotransferases, total cholesterol, and total bilirubin levels and a decrease in serum glucose concentration in a dose-dependent manner with corresponding histopathological changes in the hepatic tissues. The significant increase in malondialdehyde content and the significant decrease in glutathione content and antioxidant enzyme activities indicated that 1,3-dichloro-2-propanol-induced hepatic damage was mediated through oxidative stress, which caused a dose-dependent increase of hepatocellular apoptotic changes in the terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling assay and immunohistochemical analysis for caspase-3. The phosphorylation of mitogen-activated protein kinases caused by 1,3-dichloro-2-propanol possibly involved in hepatocellular apoptotic changes in rat liver. Furthermore, 1,3-dichloro-2-propanol induced an inflammatory response through activation of nuclear factor-kappa B signaling that coincided with the induction of pro-inflammatory mediators or cytokines in a dose-dependent manner. Taken together, these results demonstrate that hepatotoxicity may be related to oxidative stress-mediated activation of mitogen-activated protein kinases and nuclear factor-kappa B-mediated inflammatory response.

HemoHIM, herbal preparation has designed for immune system recovery. We investigated the anti-inflammatory effect of HemoHIM on cigarette smoke (CS) and lipopolysaccharide (LPS) induced chronic obstructive pulmonary disease (COPD) mouse model. To induce COPD, C57BL/6 mice were exposed to CS for 1 h per day (eight cigarettes per day) for 4 weeks and intranasally received LPS on day 26. HemoHIM was administrated to mice at a dose of 50 or 100 mg/kg 1h before CS exposure. HemoHIM reduced the inflammatory cell count and levels of tumor necrosis factor receptor (TNF)-α, interleukin (IL)-6 and IL-1β in the broncho-alveolar lavage fluid (BALF) induced by CS+LPS exposure. HemoHIM decreased the inflammatory cell infiltration in the airway and inhibited the expression of iNOS and MMP-9 and phosphorylation of Erk in lung tissue exposed to CS+LPS. In summary, our results indicate that HemoHIM inhibited a reduction in the lung inflammatory response on CS and LPS induced lung inflammation via the Erk pathway. Therefore, we suggest that HemoHIM has the potential to treat pulmonary inflammatory disease such as COPD.

The aim of this study was to verify subacute oral dose toxicity of positively charged 100 nm zinc oxide (ZnO(AE100[+])) nanoparticles (NPs) in Sprague-Dawley rats. ZnO(AE100[+]) NPs were administered to rats of each sex by gavage at 0, 500, 1,000, and 2,000 mg/kg/day for 14 days. During the study period, clinical signs, mortality, body weight, food consumption, hematology, serum biochemistry, gross pathology, organ weight, and histopathology were examined. Increased mortality and clinical signs, decreased body weight, feed consumption, hemoglobin (HB), hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), platelet (PT), and lymphocyte (LYM) and increased white blood cells (WBCs), neutrophils (NEUs), alkaline phosphatase (ALP), and histopathological alterations in the spleen, stomach, and pancreas were observed at 2,000 mg/kg/day. Increased clinical signs, decreased body weight, feed consumption, HB, HCT, MCV, MCH, MCHC, and LYM and increased WBCs, NEUs, ALP, and histopathological alterations in the spleen, stomach, and pancreas were seen at 1,000 mg/kg/day. Increased clinical signs, decreased MCV and MCH and increased histopathological alterations in the stomach and pancreas were found at 500 mg/kg/day. These results suggest that the target organs were the spleen, stomach, and pancreas in rats. The no-observed-adverse-effect level was <500 mg/kg for both sexes.

BACKGROUND: Usual interstitial pneumonia (UIP) is a progressive fibrous lung disease with occasional fatal outcomes. However, the extent and rate of progression varies markedly from one patient to another. As a result, it is difficult to determine the time of the initial treatment and assess the disease activity and course. Fibroblast foci (FF) is well known to synthesize collagen actively by their myofibroblasts component. However, the prognostic value of the FF have not been evaluated in patients with UIP. Therefore this study was undertaken to determine how the number of fibroblastic foci can reflect the disease activity and progression. METHODS: Twenty patients with UIP(M:F=13:7), who were diagnosed by a surgical lung biopsy. The number of fibroblastic foci was analyzed in terms of its correlation with the clinical manifestations. pulmonary function test, arterial blood gas analysis, and a bronchoalveolar lavage(BAL). RESULTS: The number of fibroblastic foci did not correlate with the various lung function tests and the other clinical parameters. Intersetingly, the percentage of neutrophils in the bronchoalveolar lavage fluid did correlate with the quantity of the normalized Vv of FF(r=0.60, p<0.05). The patients were divided into 2 groups, group I and II, arbitratily, according to the value of the normalized Vv. The clinical parameters and the PFT results were not different between the two groups. In particular, the survival rate between the two groups according to the Kaplan-Meier analysis were not different. CONCLUSION: A large number of FF does not imply a bad prognosis in patients wit UIP.

Artemisia argyi is used as a health supplement, tea, and food source in Korea. This study aimed to evaluate the effect of Artemisia argyi (AA) and its active compound, dehydromatricarin A (DA), on the attenuation of airway inflammation in a murine model of lipopolysaccharide (LPS)-induced acute lung injury (ALI). The C57BL/6 mice were administered AA (50 mg/kg or 100 mg/kg) and DA (10 mg/kg or 20 mg/kg) by oral gavage from day 0 to 7 days and LPS treated by intranasal instillation 48 hours before the sacrifice. The treatment of AA and DA markedly decreased inflammatory cells in the bronchoalveolar lavage fluid (BALF) compared with that in ALI-induced mice, which was accompanied by a significant reduction in the levels of tumor necrosis factor (TNF)-α and interleukin (IL)-6 in BALF. Furthermore, the administration of AA and DA clearly decreased inducible nitric oxide synthase (iNOS) expression and nuclear factor kappa B (NF-κB) phosphorylation in comparison with that in the ALI-induced mice. The histological examination of the lung tissue revealed that the administration of AA and DA suppressed the inflammatory cell infiltration into the peribronchial and alveolar lesions induced by LPS instillation. Collectively, our results indicated that AA and DA effectively decreased the airway inflammatory response induced by LPS instillation. Therefore, AA and DA may offer a potential therapy for airway inflammatory disease.
