Primary tumors of the heart are rare, three quarter of the tumors are benign, and nearly half of the benign heart tumors are myxomas. Cardiac myxoma usually originate in the left atrium about 75 percent, however, only 3 to 4 percent of myxoma are detected in the left ventricle. We report on a 32 years old woman with left ventricular myxoma who presented with shortness of breath, chest tightness, and general weakness. Acute pulmonary embolism and left ventricular myxoma were found on a perfusion lung scan and echocadiogram. A mass located on septal wall of left ventricle was excised en bloc. The patient recovered uneventfully and careful follow up has be performed periodically.

Patients with advanced carcinoma of the bladder that relapses or persists after conventional therapy have a poor prognosis. The management of the patient with recurrent local or disseminated bladder cancer presents a difficult clinical problem. In l985, Sternberg et al reported 7l% significant tumor regression and 50% complete clinical remission with M-VAC(Methotrexate, Vinblastin, Adriamycin and Cisplatin) combination chemotherapy for treatment of advanced bladder carcinoma Herein, we report 4 cases of M-VAC combination chemotherapy in far advanced bladder carcinoma with had measurable metastatic lesions enough to evaluate the objective response of chemotherapy.

This paper describes the cloning and sequence analysis of the cDNAs encoding the canine homologues of interleukin-3 (IL-3) and interleukin-6 (IL-6). The coding sequences for canine IL-3 and IL-6 were obtained by using the reverse transcription polymerase chain reaction (RT-PCR) with RNA harvested from canine peripheral blood mononuclear cells (PBMCs). Canine IL-3 cDNA includes a single open reading frame of 432 nucleotides, which encodes a 143 amino acid polypeptide and has 44.7, 42.4, 37 and 23.7% homology with the cow, sheep, human and rat IL-3 sequences, respectively. Canine IL-6 cDNA (GenBank accession number; AF275796) encodes a putative 20-amino acid signal peptide followed by a 187-amino acid mature protein. The predicted amino acid sequence of canine IL-6 shares 60.4, 77.2, 71.0, 55.8 and 42.0% sequence identity with those of human, feline, porcine, sheep and rat IL-6, respectively.

Behcet's disease is a recurrent and multisystemic disorder which usually persists over many years. In 1937 Behcet described a chronic relapsing triple symptom complex of recurrent oral ulceration, genital ulceration and ocular inflammation. Other manifestations of the syndrome include arthritis, cutaneous vasculitis, thrombophlebitis, epididymitis, ulcers of gastrointestinal tract and meningoencephalitis. Recently, a case was experienced involving intestinal Behcet's syndrome with duodenal ulcer bleeding. A 32-year-old male patient was admitted due to hematemesis, and epigastric pain. The patient had ulcers on the oral mucosa, soft palate, external genitalia, and anus. An irregularly marginated ulcer with bleeding was found on the anterior of the duodenal bulb through esophago- gastroduodenoscopic examination. The patient was diagnosed with Behcet's disease and was treated with steroids. In this paper, the case of duodenal bulb involvement of Behcet's disease is reported with a review of relevant literature.

PURPOSE: hear stress (SS) and cyclic strain (CS) influence the expression of membrane type 1-matrix metalloproteinase (MT1-MMP) in microvascular endothelial cells (MVECs). It is known that changes in the level of Sp1 phosphorylation are important for MT1-MMP expression following SS and CS. However, the exact mechanism underlying this process is poorly understood. The aim of this study was to determine the effect of PKCzeta on serine phosphorylation and activation of Sp1 in response to SS and CS. METHOD: MVECs were exposed to SS or CS for up to 8 hours with or without PKCzeta inhibitors. The activity and phosphorylation of Sp1 were assessed by Western blot analysis and immunoprecipitation. MT1-MMP protein expression was assessed by Western blot analysis. RESULT: PKCzeta was phosphorylated and activated under SS, whereas no significant changes were noted under CS. SS increased Sp1 phosphorylation in a time-dependent manner, but no changes in the Sp1 phosphorylation were observed when the MVECs were pretreated with the PKCzeta inhibitors. By contrast, MVECs exposed to CS in the presence or absence of PKCzeta inhibitors showed no change in the phosphorylation of Sp1. SS decreased MT1-MMP protein expression in a time-dependent manner, but in the presence of PKCzeta inhibitors, MT1-MMP expression was not changed compared with the static levels after SS. CS increases MT1-MMP expression in a time-dependent manner. Similar expression was observed when the cells were pretreated with PKCzeta inhibitors under CS. CONCLUSION: These data demonstrate that the increased affinity of Sp1 for the MT1-MMP's promoter site occurs because of PKCzeta induced phosphorylation of Sp1 in response to SS.

The study was undertaken to evaluate the effect of major blood components on the CT number. The CT numbers according to the various levels of hematocrit, total protein and cholesterol were checked and analysed by the dilution of pack cell, plasma and 184 complete blood cell count samples under same scanning conditions. In case of normal protein and cholesterol level(33 samples), the CT number was increased about 5.5 hounsfield unit according to 10% increase of hematocrit level: and In case of normal hematocrit and cholesterol level(39 samles), the CT number was increased about 3.5 hounsfield unit according to 1gm% increase of protein level. CT number changes were not predictable according to the changes of cholesterol level(34 samples). From these results, we concluded that major blood components should be considered in the CT number analysis of tissue.

Intraaortic balloon counterpulsation (IAB) has been shown to prolong survival in the critically ill cardiac patients. Originally developed for use in the patients with cardiogenic shock, the indications have been expanded. But despite technical advances, the complication rate associated with IAB remains high. The most commonly reported complications include damage to the femoral artery and distal embolization. Other reported major complications are balloon rupture, limb loss, bleeding, systemic infection and bowel infarction. We report a patient complicated by ischemic colitis causing stenosis and intestinal obstruction after IAB insertion.

This study was performed to evaluate the histochemical changes of the conjunctival epithelial cell in eyes with dry eye syndrome. The authors selected 10 eyes clinically diagnosed as dry eye syndrome and 2 eyes which were enucleated due to choroidal melanoma as control group. The conjunctiva was stained with ruthenium red to enhance the detection of glycoprotein in conjunctival epithelium and observed by electron microscopy. The conjunctiva with dry eye syndrome showed the epithelial stratification, elon gation of the epithelial cells, reduction of microplicae in number, and irregular distribution of mucin. These results suggest that the mucin in the conjunctiva with dry eye syndrome may be abnormal in function and may lead to clumping.
