A Case of Acute Myocardial Infraction in Patients with Dextrocardia with Situs Inversus Treated by Percutaneous Translumnal Coronary Angioplasty

Dextrocardia with situs inversus is a rare congenital anomaly of development involving a left-handed malrotation of the visceral organs which affects approximately 1:10,000 patients. It is known that the prevalence of coronary atherosclerosis in patients with dextrocardia is similar to that of the general population. Successful coronary angiography and coronary angioplasty have previously been reported in patients with dextrocardia, but to our knowledge no report exist of a successful coronary angioplasty in a patient with dextrocardia with situs inversus in Korea. We performed a successful percutaneous transluminal coronary angioplasty of an infarct-related vessel in a acute myocardial infarction patient with dextrocardia with situs inversus.

A Case of Pheochromocytoma with Acute Myocardial Infarction / 대한내분비학회지

Pheochromocytoma, the catecholamine-producing tumor of chromaffin tissue, is associated with a curable form of hypertension. Recently we report the case of a 59 year-old male admitted for an acute myocardial infarction and who subsequently developed late recurrent severe ventricular arrhythmia coincident with transient hypertensive episodes. A pheochromocytoma was diagnosed on the basis of the urinary concentration of catecholamines and computerized tomography of the adrenal glands. After stabilization of his cardiac rhythm and blood pressure with alpha adrenergic blockade, the left adrenal gland, which contained the tumor, was subsequently resected. The diagnosis of a pheochromocytoma should be considered when recurrent ventricular arrhythmia are associated with intermittent hypertension after acute myocardial infarction.

Mutagenicity Assay of Indoor Air Pollutants by Ames Test (Microsuspension assay) and Micro-nuclei of Lymphocyte / 대한산업의학회지

In order to evaluate the mutagenic effects of extractable indoor air pollutants (organic matters), we measured the mutagenic activities by sensitive microsuspension Ames test using new tester strains (YG 1024 and YG 1029). And additionally to evaluate the mutagenic effects on vital cell, we examined the frequencies of micronucleus appearing in lymphocytes from dye handling workers and controls. This study was conducted from Jan. toMay, 1995. The extractable indoor air pollutants were collected by low volume air sampler in a general office room and 3 of dye handling factories. And the environment of general office room divided into 3 different groups according to the type of room heaters. To determine the frequencies of micronucleus appearing in lymphocytes, we sampled peripheral venous blood from 20 of dye handling workers and 20 of controls, and cultured, and then examined the lymphocytes. The results obtained were as follows: 1. The indirect mutagenic activities of extractable organic matters from suspended particulates colleced in a general office room were higher than the direct one. 2. The strain YG 1024 was the most sensitive, and the increasing order of test strainsthat showed higher number of revertant were YG 1024, YG 1029, TA 100, and TA 98. 3. In the general office room, the room using kerosene heater showed the highest mutagenecity, and the next was buthan gas heater, and non-heating room in order. 4. The mutagenic effects of suspended particulates in::dye handling factories on the strain YG 1024 was 1.2 times higher than YG 1029. 5. The frequencies of micronucleus appearing in lymphocyte of the circulating blood of dye handling workers and the control were 5.65+/-2.97% and 4.65+/-0.97%, respectively. And the difference was statistically significant.
