Clinical study was done on 119 patients with atrial fibrillation in the aspect of underlying diseases, particulary. The results were as follow : 1) In the underlying diseases of atrial finbrillation, rheumatic heart disease, hepertension and ischemic heart disease were common, which occupied 27.8%, 22.7% and and 15.1%, respectly. No apparent underlying disease was found in 21.0%, but in the transient atrial fibrillation, no apparent underlying disease in 42.9%. 2) There were no significant correlations between the ventricular rate, amplitude of f wave and underlying diseases of atrial fibrillation. 3) Complications were found in 29.4% of all cases, such as congestive heart failure(22.7%), embolism(6.7%). Otherwise, atrial fibrillation without underying cardiovascular diseases, congestive heart failure was found only(7.7%).

Atrial fibrillation is one of the most common cardiac arrhythmias requiring treatment. About 60% of patients with mitral valvular disease have atrial fibrillation and one third of the patients with atrial fibrillation may have the past history of thromboembolic events. Between April 1994 and June 1995, 20 patients with organic heart diseases combined with atrial fibrillation underwent open heart surgery including Cox-maze III procedure. There were 6 men and 14 women with an average age of 48 years (range, 31 to 66 years). Nineteen patients had valvular heart diseases and 1 ventricular septal defect (VSD). Mean duration of atrial fibrillation was 36 months (+/-42 months) (range, 1 to 132 months). The past medical history of thromboembolic events was positive in 7 patients (35%) and left atrial thrombi was detected in 9 patients (45%). The concomitant procedures were mitral valve replacement (MVR) and aortic valve replacement (AVR) in 5 patients, MVR in 4, MVR and tricuspid annuloplasty (TAP) in 4, mitral valvuloplasty (MVP) in 3, MVP and TVP in 1, MVP and coronary artery bypass surgery in 1, AVR in 1, and patch closure of VSD in 1. Mean aortic cross-clamping time was 175 minutes (range, 116 to 270 minutes). Atrial fibrillation recurred in 16 patients (80%) during the early postoperative period, however, the recurrent atrial fibrillation converted to regular rhythm at postoperative forty-first day in average. There was no early or late death in this series of 20 patients and postoperative complications were inappropriate tachycardia in 5 patients (25%), low cardiac output syndrome in 3 (15%), aggravated hemiplegia in 1, and acute renal failure in 1. Mean follow-up interval of the patients was 16.5 months (range, 10.5 to 24 months) and all the patients are currently in regular rhythm. Seventeen patients (85%) are in sinus rhythm and 3 (15%) in junctional rhythm. Right atrial contraction was detected in 95% of patients and left atrial contraction in 63% on postoperative transthoracic echocardiogram. The surgical treatment of atrial fibrillation concomitant with open heart surgery is warranted in the recent clinical setting of improved myocardial protection technique, considering the untoward side-effects of atrial fibrillation.

BACKGROUND: It has been well documented that transient occlusion of the coronary artery causes myocardial ischemia and finally cell death when ischemia is sustained for more than 20 minutes. Extensive studies have revealed that ischemic myocardium cannot recover without reperfusion by adequate restoration of blood flow, however, reperfusion can cause long-lasting cardiac dysfunction and aggravation of structural damage. The author therefore attempted to examine the effect of postischemic reperfusion on myocardial ultrastructure and to determine the rationales for recanalization therapy to salvage ischemic myocardium. MATERIALS AND METHODS: Young Holstein-Friesian cows (130~140 Kg body weight; n=40) of both sexes, maintained with nutritionally balanced diet and under constant conditions, were used. The left anterior descending coronary artery (LAD) was occluded by ligation with 4-0 silk snare for 20 minutes and recanalized by release of the ligation under continuous intravenous drip anesthesia with sodium pentobarbital (0.15 mg/Kg/min). Drill biopsies of the risk area (antero-lateral wall) were performed at just on reperfusion (5 minutes), 1-, 2-, 3-, 6-, 12-hours after recanalization, and at 1-hour assist (only with mechanical respiration and fluid replacement) after 12-hour recanalization. The materials were subdivided into subepicardial and subendocardial tissues. Tissue samples were examined with a transmission electron microscope (Philips EM 300) at the accelerating voltage of 60 KeV. RESULTS: After a 20-minute ligation of the LAD, myocytes showed slight to moderate degree of ultrastructural changes including subsarcolemmal bleb formation, loss of nuclear matrix, clumping of chromatin and margination, mitochondrial destruction, and contracture of sarcomeres. However, microvascular structures were relatively well preserved. After 1-hour reperfusion, nuclear and mitochondrial matrices reappeared and intravascular plugging by polymorphonuclear leukocytes or platelets was observed. However, nucleoli and intramitochondrial granules reappeared within 3 hours of reperfusion and a large number of myocytes were recovered progressively within 6 hours of reperfusion. Recovery was apparent in the subepicardial myocytes and there were no distinct changes in the ultrastructure except narrowed lumen of the microvessels in the later period of reperfusion. CONCLUSIONS: It is likely that the ischemic myocardium could not be salvaged without adequate restoration of coronary flow and that the microvasculature is more resistant to reversible period of ischemia than subendocardium and subepicardium. Therefore, thrombolysis and/or angioplasty may be a rational method of therapy for coronarogenic myocardial ischemia. However, it may take a relatively longer period of time to recover from ischemic insult and reperfusion injury should be considered.

OBJECTIVE: To investigate the effects of botulinum toxin on the mechanical hyperalgesia, electrophysiology and motor functions in the persistent muscle pain rat model. METHOD: A secondary mechanical hyperalgesia in the bilateral hindpaws of Sprague-Dawley rats was produced by the repeated injections of acidic saline into gastrocnemius. Botulinum toxin A (BTX-A(4): 4 U/kg, BTX-A(7): 7 U/kg) was administrated into same muscle 24 hours after a second injection of saline. The mechanical hyperalgesia was measured with withdrawal threshold to von Frey filament. The grade of muscle paralysis was evaluated with electrophysiology and the locomotor performance using inclined plane board. RESULTS: The mechanical hyperalgesia was significantly decreased from 5 days to 2 weeks in BTX-A(7) group in the injected side. The dose-dependent decreased amplitude of compound muscle action potential and reduced prevalence of endplate noise from the first day of botulinum toxin injection lasted for 4 weeks in both gastrocnemius. The maximum angle maintained at initial position on the inclined plane board did not change. CONCLUSION: Local muscular injection of botulinum toxin A reduced ipsilateral hyperalgesia dose-dependently in persistent muscle pain rat model without motor deficit. The antinociceptive mechanism of botulinum toxin might act at a local or peripheral rather than a systemic or central effect due to ineffectiveness of contralateral hyperalgesia. Clinically, botulinum toxin A might be useful for the treatment of local and referred pain of muscle origins.

We present a patient with primary hyperparathyroidism in whom preoperative Tc-99m sestarnibi scanning cleary demonstrated mediastinal parathyroid adenoma. After resectian of tumor through median sternotomy, he was restored to the normocalcemia. This case suggests that Tc-99m sestamibi scanning may be a useful method in the preoperative localization of mediastinal parathyroid adenoma.

BACKGROUND: Long-term survival after surgical correction of mitral regurgitation is associated with preservation of left ventricular systolic function after operation. And mitral valve repair has been suggested to provide a better postoperative left ventricular systolic function. Accordingly, we intended to compare the operative results of mitral valve repair with those of mitral valve replacement and search for preoperative predictors of postoperative left ventricular systolic function. METHOD: The clinical features, echocardiographic measurements, and cardiac catheterization results of 75 patients operated between January 1984 and December 1994 for acquired pure mitral regurgitation were analyzed. RESULTS: Of the 75 patients, 39 patients had mitral valve repair, and 36 patients had mitral valve replacement. When the outcomes of mitral valve repair and mitral valve replacement were compared, left ventricular ejection fraction decreased significantly after surgery inboth groups but postoperative left ventricular ejection fraction was greater in valve repair group than in valve replacement group. Data analysis of preoperative variables showed that echocardiographic left ventricular end-diastolic diameter(p<.05), but not other clinical and echocardiographic variables, were predictors of postoperative left ventricular systolic function. CONCLUSION: After surgical correction of chronic organic mitral regurgitation, left ventricular dysfunction is frequent and valve repair decreases the severity of left ventricular dysfunction. And the most powerful predictor of postoperative left ventricular systolic function is preoperative left ventricular end-diastolic diameter measured by echocardiography.

BACKGROUND/AIMS: Halitosis is a symptom that bothers patients more socially than medically and its pathogenic mechanisms are unclear and treatment armamenterium is limited. Clinicians generally ignored active interventions. Since halitosis is closely associated with volatile sulfur compounds (VSCs), we used a Halimeter and gas chromatography to measure VSCs in patients with Helicobacter-pylori (H. pylori)-associated gastric diseases. METHODS: We categorized 72 patients with H. pylori infection into two groups based on their endoscopic findings: a non-erosive mucosal group (NE, n=24) and an erosive mucosal group (E, n=48). Halitosis was objectively assessed by applying either a Halimeter to breath air or gas chromatography to gastric juice. Simultaneously, the expression of VSC-generating enzyme was measured with reverse-transcriptase PCR using mRNA isolated from biopsy tissues. RESULTS: The levels of VSCs in exhaled breaths or aspirated gastric juices differed significantly between the NE and E groups (p<0.00001), suggesting that VSCs might reflect eroded epithelial damage induced by H. pylori infection. The expressions of cystathionine beta-synthase (CBS) and cystathionine gamma-lyase (CSE) were broadly consistent with the degree of mucosal injury. CONCLUSIONS: Erosive changes in esophagogastroduodenal mucosa were strongly correlated with increased VSC levels, suggesting that halitosis might result from H. pylori-associated erosive lesions.
