The clinical effect of doxazosin mesylate, a selective long acting alpha-1 adrenergic blocker, were evaluated in 31 patients with symptomatic benign prostatic hyperplasia ranging from 49- 85 years old. All patients underwent a urodynamic evaluation and symptom score checking before enrollment into the study. The dose of doxazosin was 2mg per day. And the mean duration of treatment was 157 days. 31 patients were followed on doxazosin for 3 to 12 months with mean 7.5 months. The adverse drug reactions were observed only 1 case. The parameters used to assess the effectiveness of doxazosin included peak and mean urinary flow rates, micturition symptom scores and residual urine, and global assessment by the patient The peak and mean urinary flow rates increased by 77% and 86%, respectively. The obstructive and irritative symptom scores were improved by 51% and 41% respectively. The improvements in urinary flow rates and symptom scores were maintained for this interval. Although this preliminary experience with doxazosin is encouraging, the ultimate role of doxazosin for the long term treatment of benign prostatic hyperplasia needs further evaluation.

Amyloidosis is an acquired or inherited disorder with protein folding and degradation characterizing the deposition of the proteinaceous material in the extracellular matrix of one or several organs. Secondary amyloidosis resulting from the deposition of serum amyloid A protein, occurs 1-5% during the lifetime of patients with chronic inflammatory disorders such as rheumatoid arthritis and ankylosing spondylitis. In addition, chronic pyelonephritis and pressure sores in patient with spinal cord injury are documented as risk factors of secondary amyloidosis. Thus, the efforts to treat and prevent the development of secondary amyloidosis and to preserve the renal function should focus on avoiding the chronic inflammatory state and a pathologic study of doubtful organs for early diagnosis should be performed. We have experienced one case of secondary amyloidosis in patient with spinal cord injury which involves with kidney and thyroid gland.

Human skin cells undergo pathophysiological processes via generation of reactive oxygen species (ROS) upon excessive exposure to ultraviolet B (UVB) radiation. This study investigated the ability of hesperidin (C28H34O15) to prevent apoptosis due to oxidative stress generated through UVB-induced ROS. Hesperidin significantly scavenged ROS generated by UVB radiation, attenuated the oxidation of cellular macromolecules, established mitochondrial membrane polarization, and prevented the release of cytochrome c into the cytosol. Hesperidin downregulated expression of caspase-9, caspase-3, and Bcl-2-associated X protein, and upregulated expression of B-cell lymphoma 2. Hesperidin absorbed wavelengths of light within the UVB range. In summary, hesperidin shielded human keratinocytes from UVB radiation-induced damage and apoptosis via its antioxidant and UVB absorption properties.

In contrast to the idiopathic cause of intussusception in children, adult intussusception in most patients is associated with organic causes. The majority of these patients are brought to the operating room with the preoperative diagnosis of bowel obstruction, and the surgeon discovers an intussusception intraoperatively. But the increasing use of abdominal CT may improve the ability to diagnose intussusception. There is no universal agreement upon the correct treatment of adult intussusception, although most authors agree that surgical intervention is necessary. In the more recent reports, colonoscopic reduction of intussusception has been reported for selected patients. For patients in whom the involved ileum is extremely long, it is advisable to attempt an operative reduction or colonoscopic reduction selectively. Thus, we report here on two patients with benign and malignant lesion, respectively, that caused ileocolic intussusception; preoperative colonoscopic diagnosis and reduction were attempted for these patients, although the patients were not reduced by colonoscopic procedure.

N-butyl-2-cyanoacrylate (Histoacryl(R)) is used to obtain hemostasis in gastric variceal bleeding. Known complications of Histoacryl(R) injection therapy include bleeding, perforation, stenosis, and embolism. We report a case of adrenal abscess as a very rare complication of Histoacryl(R) injection. A 40-year-old male with liver cirrhosis was admitted with acute gastric variceal bleeding. Sclerotherapy using Histoacryl(R) mixed with lipiodol (3 mL) was successful. Twenty-seven months later, he was readmitted complaining of left flank pain and a fever of 39degreesC. Abdominal computed tomography (CT) showed a heterogeneous enhancing solid and cystic mass (6.1x3.0 cm) at the left adrenal gland. A left adrenalectomy was performed and the pathological examination confirmed a Histoacryl(R)-related adrenal abscess. We present this case along with a brief review of the literature

Previously, we demonstrated that galangin (3,5,7-trihydroxyflavone) protects human keratinocytes against ultraviolet B (UVB)-induced oxidative damage. In this study, we investigated the effect of galangin on induction of antioxidant enzymes involved in synthesis of reduced glutathione (GSH), and investigated the associated upstream signaling cascades. By activating nuclear factor-erythroid 2-related factor (Nrf2), galangin treatment significantly increased expression of glutamate-cysteine ligase catalytic subunit (GCLC) and glutathione synthetase (GSS). This activation of Nrf2 depended on extracellular signal-regulated kinases (ERKs) and protein kinase B (AKT) signaling. Inhibition of GSH in galangin-treated cells attenuated the protective effect of galangin against the deleterious effects of UVB. Our results reveal that galangin protects human keratinocytes by activating ERK/AKT-Nrf2, leading to elevated expression of GSH-synthesizing enzymes.

A mushroom bezoar is an unusual type of bezoar and a rare cause of small bowel obstruction, with the only cases being previously described in the foreign literature. Common sites of obstruction are the gastric outlet, the terminal ileum as well as segments of pre-existing gastrointestinal stenosis of various etiologies. Predisposing factors include a high fiber intake, inadequate chewing, gastric hyposecretion and hypomotility, and a previous gastrectomy and vagotomy. Computed tomography has the capability of directly showing the bezoar and displaying the resulting small bowel obstruction. We report a case of incomplete small bowel obstruction in a 38-year-old woman, caused by a mushroom bezoar in the terminal ileum.

PURPOSE: The optimal indications for omitting adjuvant radiation therapy (RT) after breast-conserving surgery are still controversial in ductal carcinoma in situ (DCIS) of the breast. The purpose of this study was to validate the role of postoperative RT in DCIS patients aged ≤50 years and with tumor margin widths of <1 cm, both of which have been proven to be high-risk features for recurrence in cohorts not receiving RT. METHODS: Using two multicenter retrospective studies on DCIS, a pooled analysis was performed among patients aged ≤50 years and with margin widths < 1 cm. All patients underwent breast-conserving surgery. Two hundred thirty-two patients received postoperative RT, while 54 did not. The median follow-up period was 77 months (range, 2–190 months) and 70 months (range, 5–166 months) in the patients who received RT and those who did not, respectively. RESULTS: The patients who received RT had larger tumors (p < 0.001), higher nuclear grade (p < 0.001), closer margin width (p < 0.001), and negative estrogen receptor expression (p=0.010) compared with those who did not receive RT. During the follow-up period, there were 17 ipsilateral breast tumor recurrences (IBTRs) as follows: invasive carcinoma in 10 patients and DCIS in seven. In the univariate analysis, the treatment with RT and human epidermal growth factor receptor 2 (HER2) status were significant risk factors for IBTR. The 7-year IBTR rates with and without postoperative RT were 3.6% and 13.1%, respectively (p=0.008). HER2-positive tumors had a higher IBTR rate than the HER2-negative tumors (7-year rate, 13.6% vs. 3.9%; p=0.003). CONCLUSION: Postoperative RT following breast-conserving surgery significantly reduced the 7-year IBTR rate in the DCIS patients aged ≤50 years and with margin widths < 1 cm. HER2 positivity was associated with increased IBTR in these patients.

We investigated the role of autophagy in SNUC5/5-FUR, 5-fluorouracil (5-FU) resistant SNUC5 colon cancer cells. SNUC5/5-FUR cells exhibited low level of autophagy, as determined by light microscopy, confocal microscopy, and flow cytometry following acridine orange staining, and the decreased level of GFP-LC3 puncta. In addition, expression of critical autophagic proteins such as Atg5, Beclin-1 and LC3-II and autophagic flux was diminished in SNUC5/5-FUR cells. Whereas production of reactive oxygen species (ROS) was significantly elevated in SNUC5/5-FUR cells, treatment with the ROS inhibitor N-acetyl cysteine further reduced the level of autophagy. Taken together, these results indicate that decreased autophagy is linked to 5-FU resistance in SNUC5 colon cancer cells.
