Successful percutaneous transluminal angioplasty (PTA) of an internal mammary artery graft was performed in a 40 year old male patient who had recurrent angina soon after bypass surgery. Coronary angiography showed total occlusion of proximal portion of the left anterior descending artery and normal right coronary artery. Angiography of the left internal mammary artery graft revealed a tight stenosis (90% diameter narrowing) in the mammary artery at its insection into the left anterior descending artery.Angiography after the angioplasty demonstrated a widely patent graft (residual stenosis 10%) and translesional pressure gradient was 10 mmHg.

Pheochromocytoma is originated from chromaffin cell of sympathetic nervous system and associated with other disease, such as neurofibromatosis, duodenal carcinoid, medullary thyroid cancer and parathyroid adenoma. Especially, pheochromocytoma is developed more than 50% in neurofibromatosis associated with hypertension. In such cases, several clinical features documented as more frequent bilateral phochromocytoma, more associated with other neuroendocrine tumors and thus more poor prognosis. We can observe the sustained hypertension despite of surgical resection of tumors in pheochromocytoma cases. One of the possible reason of post operative sustained hypertension is the pheochromocytoma originated from minor organ of Zukerkandl that was not resected during operation. Untreated or delayed treated cases with pheochromocytoma were often expired by complication of hypertension such as cerebrovascular hemorrhage, myocardial infarction, etc. Thus, in neurofibromatosis with hypertension, screening of pheochromocytorna is very important for the early detection of tumor and more favorable prognosis. Recently, We experienced a case of neurofibromatosis associated with bilateral pheochromocy-toma expired by cerebral hemorrhage during operation, so we report the case with literature review.

In the course of immunoscreening of Clonorchis sinensis cDNA library, a cDNA CsRP12 containing a tandem repeat was isolated. The cDNA CsRP12 encodes two putative peptides of open reading frames (ORFs) 1 and 2 (CsRP12-1 and -2). The repetitive region is composed of 15 repeats of 10 amino acids. Of the two putative peptides, CsRP12-1 was proline-rich and found to have homologues in several organisms. Recombinant proteins of the putative peptides were bacterially produced and purified by an affinity chromatography. Recombinant CsRP12-1 protein was recognized by sera of clonorchiasis patients and experimental rabbits, but recombinant CsRP12-2 was not. One of the putative peptide, CsRP12-1, is designated CsPRA, proline-rich antigen of C. sinensis. Both the C-termini of CsRP12-1 and -2 were bacterially produced and analysed to show no antigenicity. Recombinant CsPRA protein showed high sensitivity and specificity. In experimental rabbits, IgG antibodies to CsPRA was produced between 4 and 8 weeks after the infection and decreased thereafter over one year. These results indicate that CsPRA is equivalent to a natural protein and a useful antigenic protein for serodiagnosis of human clonorchiasis.

We report a case of coronary artery-pulmonary artery fistula in 53-year-old man with review of literature. He complained of anterior chest pain with tightness, but all physical findings were normal. Routine laboratory findings in cluding EKG and chest PA were normal. For evaluation of angina, we performed the coronary arteriogram and established the diagnosis of coronary artery-pulmonary artery fistual incidentally. There was no hemodynamic significance.

An important aspect of plastic surgery is skin flap survival. Among the prostaglandins, PGE4 is used clinically to improve peripheral circulatory disturbances due to its action of augmenting blood flow by vascular smooth muscle relaxation and its strong inhibitory action of platelet aggregation. Clinically, many investigators found that the effect of PGE4 was prolonged for a long period even after short-term application. So a new hypothesis emerges that the prolonged effect of PGE4 may be due to neovascularization and not due to vasodilatation alone. This study was designed to clarify the mechanism of the prolonged effect of topical PGE4 with regard to angiogenesis. A total of 9 male hairless mice were treated with a topical application of PGE4 onitment (PGE4 powder mixed in hydrogen base) on the experimental side and only a hydrogen base on the contralateral control side of the back skin, respectively, for 7 days, once a day. Then they were divided into 3 groups. In group 1, specimens were obtained on the 7th day post-treatment using 3 mm size punch biopsy from both sides. In group 2, specimens were obtained on post-treatment 14th day. In group 3, specimens were obtained on post-treatment 28th day. The number of blood vessels were compared between the experimental side and control side with respect to neovascularization after PGE4 application using an image-analysis program under hemtoxyline-eosin stain. Treatment on the experimental side did not affect its contralateral mate, since there was no evidence of a systemic effect. From our experimental data, we could conclude that PGE4 may induce angiogenesis by topical application without systemic effect.

Profound reduction of anterograde coronary flow with concomitant ischemia is seen occasionally during percutaneous coronary intervention despite technically successful procedure. We found interesting coronary flow pattern in a patient with acute myocardial infarction, showing angiographic no reflow phenomenon after direct PTCA. The coronary blood flow pattern of the angiographic no-reflow phenomenon in this case was characterized by minimal systolic flow and sharp deceleration of diastolic flow. Coronary flow reserve calculated by the ratio of adenosine induced maximal hyperemic velocity and basal velocity was reduced. The Dopplertipped guide wire was useful for observation of phasic coronary flow pattern of angiographic no-reflow phenomenon.
