To examine the effect of retinal branch vein occlusion (BRVO) on protein tyrosine phosphorylation, production of angiogenic growth factors, and activation of signal proteins in the tyrosine kinase pathways in the retina, BRVO was induced in cat retina by coagulation of retinal veins with diathermy. At 2 days, 1, 3, and 6 weeks after induction of BRVO, the retina was divided into 3 parts; a part within the distribution of the occluded vein [BRVO(IN)] or a part outside the distribution of the occluded vein [BRVO(OUT)], an prepared for western blot analysis. Overall, tyrosine-phosphorylated proteins were increased after BRVO, especially in BRVO(IN) at 2 days and 1 week. The vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) were also increased in BRVO(IN) at 1 week and 2 days, respectively. The phospholipase Cgamma(PLCgamma) and mitogen-activated protein kinase (MAPK) were activated at these points. In this study, we concluded that the BRVO increased overall protein tyrosine phosphorylation in the cat retina in association with the increase of angiogenic growth factors (VEGF, bFGF) and activation of 2 signal proteins (PLCgamma and MAPK)in the tyrosine kinase pathways. These results suggest that the protein tyrosine phosphorylation may in part play an important role in mitogenesis of vascular endothelial cells and other retinal responses after BRVO.

The aim of this study was to assess the involvement of multipotential progenitor cells in the pathogenesis of Mooren's ulcer using immunohistochemical staining techniques. Tissue specimens were collected from 3 Mooren's ulcer patients who underwent lamellar keratectomy. Immunohistochemical staining patterns were analyzed using antibodies: CD34, c-kit, STRO-1, CD45RO, VEGF and alpha-SMA. Strong positive CD34, c-kit and STRO-1 cells were revealed in Mooren's ulcer specimens, especially in the superficial stroma. A few weakly expressed CD34 stroma cells were seen in normal limbal cornea but no immunoreactivity for c-kit and STRO-1 could be found. CD45RO positive T cells were found to have infiltrated in Mooren's ulcer. The immunostaining pattern of VEGF and yen a- SMA was closely correlated with the degree of expression and the number of CD34 positive cells. Bone marrow-derived multipotential progenitor cells may be involved in the pathogenesis of Mooren's ulcer by synergizing with other factors to amplify autoimmune destructive reactions and to contribute to the regeneration process. Specific therapeutic strategies that target the role of these cells in the disease are warranted.

OBJECTIVE: Prostate cancer is the most common cancer in men and localized prostate adenocarcinoma has multiple treatment options. In this study, the objective was to review the outcome of patients that were treated with HDR brachytherapy as monotherapy in all prostate adenocarcinoma patients at the St Luke's Medical Center.

MATERIALS AND METHODS: Thirty three (33) patients who underwent HDR prostate brachytherapy as monotherapy for prostate adenocarcinoma in a single institution for the past 5 years received 38 Gy in 4 fractions. The charts of these patients were reviewed to determine biochemical control using the Phoenix criteria and ASTRO definition, and toxicity.

RESULTS: Patients showed good biochemical control, with 92.16% meeting the target PSA value of 2 ng/mL or less and a 96.51% without consecutive rise of PSA post brachytherapy. There was also minimal toxicity, with no report of gastrointestinal toxicity and 9.1% rate of temporary genitourinary toxicity.

CONCLUSION: Good biochemical control of prostate adenocarcinoma was achieved with the use of HDR brachytherapy as monotherapy, with a minimal toxicity profile.

Immune checkpoint inhibitor (ICI) associated cardiovascular adverse events (CVAE) have become more frequent with the growing use of cancer immunotherapy. CVAEs include a wide spectrum of diseases such as myocarditis, pericarditis, heart failure, arrhythmias, coronary artery disease, and hypertension. The induction of cardiovascular side effects by ICI use is hypothesized to occur due to inflammation and immune dysregulation of normal tissue in response to immunotherapy. Management of ICI-associated CVAEs mitigates an overactive immune response by utilizing steroids, immunomodulatory drugs and hemodynamic stabilization. However, few controlled studies on the cardiovascular safety of ICIs exist and treatment of their side effects are mostly from limited case series. Our review seeks to provide the most recent understanding of ICI-associated CVAEs and their management.

PURPOSE: The optimal initial treatment for burn wound is generally applying cold running tap water of temperature 12~18degrees C for approximately 20 minutes. But most of the patients are not susceptible to this initial treatment because they are likely to get embarrassed in such situation. According to statistics of our hospital, 92.2% of patients who visited ER (emergency room) had less than 10 minutes of water cooling. In this study, our aim was to find out the clinical effect of biocellulose sheet (Bestian M(R) pack) as an emergent treatment. METHODS: Between November 2010 and October 2011, 93 patients with burn wound showing first or superficial second degree at first inspection were evaluated in our study. Biocellulose sheet (Bestian M(R) pack) was applied at the wound as soon as possible for 25 minutes and second inspection was done. Routine moisture dressing was done thereafter and patients were followed as outpatient. RESULTS: Among 93 patients, 28 were male and 65 were female. Scalding burn, contact burn, flame burn and other causes were 78, 6, 4 and 5 patients respectively. Average complete healing time was 7.99 days and average follow-up time was 5.49. CONCLUSION: Biocellulose sheet has the effect of cooling down the skin temperature up to 6~8degrees C after 10 minutes of its application. Recent studies reported that appropriate cooling in burn wound improves the zone of stasis and zone of erythema histologically eventually reducing the chance of skin graft. Therefore, biocellulose sheet has the effect of improving initial pain, histologic status, healing time and cost in patients with burn wound whose depth is not deep. Furthermore it reduces the risk of scar formation.

Intracranial large artery disease (ILAD) is the major cause of stroke worldwide. With the application of recently introduced diagnostic techniques, the prevalence of non-atherosclerotic ILAD is expected to increase. Herein, we reviewed recent reports and summarized progress in the diagnosis and clinical impact of differentiation between ILAD of atherosclerotic and non-atherosclerotic origin. Our review of the literature suggests that more careful consideration of non-atherosclerotic causes and the application of appropriate diagnostic techniques in patients with ILAD may not only provide better results in the treatment of patients, but it may also lead to more successful clinical trials for the treatment of intracranial atherosclerosis.

More than half of the world’s populations are considered to be infected by Helicobacter pylori. It causes a chronic inflammation of the stomach, which is implicated in the pathogenesis of gastric ulcer and cancer. Silibinin, a polyphenolic flavonoid derived from milk thistle, has been known for its hepatoprotective effects, and recent studies have revealed its chemopreventive potential. In the present study, we examined the anti-inflammatory effects of silibinin in human gastric cancer MKN-1 cells and in the stomach of C57BL/6 mice infected by H. pylori. Pretreatment with silibinin attenuated the up-regulation of COX-2 and inducible nitric oxide synthase (iNOS) in H. pylori-infected MKN-1 cells and mouse stomach. In addition, the elevated translocation and DNA binding of NFκB and STAT3 induced by H. pylori infection were inhibited by silibinin treatment. Moreover, H. pylori infection in combination with high salt diet resulted in dysplasia and hyperplasia in mouse stomach, and these pathological manifestations were substantially mitigated by silibinin administration. Taken together, these findings suggest that silibinin exerts anti-inflammatory effects against H. pylori infection through suppression of NF-κB and STAT3 and subsequently, expression of COX-2 and iNOS.
