1.The Effect of Oral Mexiletine on Ventricular Arrhythmias Evaluation by Holter Monitoring.
Korean Circulation Journal 1985;15(3):441-446
The antiarrhythmic effect of oral Mexiletine was evaluated by Holter monitoring on 10 subjects with chronic high-frequency ventricular premature complexes and ventricular tachycardia referred to our cardiology clinic of Severance Hospital from June, 1982 through September, 1983. The frequency of the ventricular premature complexes and the ventricular tachycardia was measured by 24-hour ambulatory electrocardiography on each patient before and during the administration of Mexiletine(450-600 mg/day). The results were as follows : 1) In 10 patients with ventricular tachycardia total suppression of ventricular tachycardial was demonstrated in 8 patients during the administration of oral Mexilletine. 2) The number of the ventricular premature complexes was reduced markedly in 6 out of the 10 patients. 3) Side effects occurred in 5 out of 10 patients. These include tremor, weakness, dry mouth, indigestion, anorexia, chest discomfort, and dizziness but were tolerated except in one.

Intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) are weakly expressed in normal glomerular cells and vascular endothelial cells, but not in tubules. Granzyme B is a cytotoxic granule present in activated cytotoxic T cells and natural killer cells. To determine the effect of ICAM-1 and VCAM-1 expression and granzyme B-positive cells on histologic grade of rejection, we performed the immunohistochemical study on 19 renal biopsy specimens and one nephrectomy specimen from 14 patients with acute renal allograft rejection using monoclonal antibodies against theses proteins. According to severity of rejection based on Banff classification, three biopsies were classified as borderline, 4 grade I, 12 grade II, and 1 grade III. In all the cases with acute rejection, ICAM-1 and VCAM-1 were expressed in the tubular epithelial cells. The numerical score of ICAM-1 in the tubular epithelial cells was 1.0 in borderline cases, 1.3 0.4 in grade I cases, 2.2 0.8 in grade II cases, and 3.0 in grade III case. The staining intensity of ICAM-1 in the tubular epithelial cells was increased in accordance with histologic rejection grade (P<0.05). The staining intensity of ICAM-1 and VCAM-1 in the renal tubular epithelial cells was increased in accordance with the number of T lymphocytes in the renal parenchyme (r=0.46; P<0.05, r=0.61; P<0.01). The number of granzyme B-positive cells was 6.4 1.6/HPF in borderline cases, 8.1 2.5 in grade I cases, 19.6 11.7 in grade II cases, and 53 in grade III case. The number of T lymphocytes and granzyme B-positive cells was also increased in accordance with histologic rejection grade (P<0.05). These results suggest that ICAM-1 and granzyme B-positive cells may play an important role in the induction of renal allograft rejection and that the grading of severity of these parameters may be useful to predict the prognosis of renal allograft.

BACKGROUND: Aprotinin, which is a nonspecific serine protease inhibitor, has an antiinflammatory and thrombogenic effect. However, it has an antithrombogenic effect during the cardiopulmonary bypass. This study was performed to evaluated the effects of aprotinin on the activated clotting time(ACT) and the total amount of the heparin used during the cardiopulmonary bypass. MATERIAL AND METHOD: From December 1998 to November 1999, 82 consecutive patients electively underwent open heart surgery at Gachon medical school. The patients were older than 18 years. Eighty two patients were classified into a control group(group C, n=36) and a aprotinin-treated group(group A, n=46). Body weight, height, body surface area(BSA), pump time(PT), aortic cross clamping time(ACCT), and body temperature(BT) were determined. Total amount of heparin and protamine during the CPB were also measured. ACT was determined before heparin administration, at 20, 40 and 60 minutes after heparin administration, and after protamine administration. RESULT: No significant differences were noted in either group in body weight, height, BSA, BT, and the total amoun of heparin and protamine. Group A demonstrated a significant(p<0.05) increase in age, PT, ACCT, and ACT at 20, 40, and 60 minutes after heparin administration. CONCLUSION: In summary, the use of aprotinin prime resulted in an increase in ACT. The total amount of heparin in aproinin-treated patient was similar to that of the control group in spite of having the prolonged pump time. Therefore aprotinin may reduce the requirement of heparin.

Renal blood flow was measured by single injection technique of HippuranI13 in 13 patients with chronic glomerulonephritis and 11 control subjects. There was a significant decrease in renal blood flow in chronic glomerulonephritis particulary in those with elevated blood urea nitrogen. Renal blood flow was inversely proportionate to renal vascular resistance but no correlation was noted between renal blood flow and creatinine clearance.

Glomerulosclerosis represents a pathological hallmark of progressive glomerular injury. Mesangial cell proliferation and accumulation of extracellular matrix (ECM) proteins in the mesangial area frequently precede the formation of glomerulosclerosis. To understand the role of platelet-derived growth factor (PDGF) and ECM in the development of glomerulosclerosis, we examined the expression of type IV collagen, laminin, fibronectin, and PDGF in 45 renal biopsies diagnosed with IgA nephropathy (IgAN) using a standard peroxidase antiperoxidase (PAP) technique. Normal control specimens were obtained from four nephrectomy specimens diagnosed with renal cell carcinoma. As compared with normal controls, type IV collagen increased in 68%, fibronectin in 73%, laminin in 51%, and PDGF in 36% of patients with IgA nephropathy. The staining intensity of PDGF, type IV collagen, and fibronectin increased significantly in cases with moderate to severe mesangial cell proliferation than cases without. In the areas of glomerulosclerosis, the staining intensity of type IV collagen, laminin, and PDGF decreased, whereas that of fibronectin increased. These results suggest that mesangial cell proliferation in relation to increased PDGF expression in IgAN could stimulate the expression of type IV collagen, laminin and fibronectin leading to mesangial expansion. They also suggest that ECM decreased in advanced glomerulosclerosis. Deposition of fibronectin, which originates mainly from the blood stream, increases during the course of progressive glomerulosclerosis, whereas other ECM components decrease in advanced glomeruloslresosis.

OBJECTIVES: The aim of this study was to know differences of characteristics between presenile and senile patients who were consulted to the department of psychiatry during medical-surgical admission. METHODS: The demographic and clinical data obtained from the medical records of psychiatric consultation in the presenile inpatients with age 50 to 64 years(N=162) and those of the senile inpatients with age over 65 years(N=171) were reviewed and compared. RESULTS: 1) The most common chief complaints for psychiatric consultation in presenile patients were somatic symptoms, anxiety and sleep disturbance in order, while cognitive decline, clouded consciousness and depressed mood were most common in senile patients with statistical significance. 2) The most frequent psychiatric diagnoses after consultation in presenile patients were delirium, mood disorder and substance use disorder in order, while delirium, mood disorder and major neurocognitive disorder were most frequent in senile patients with statistical significance. 3) There were no significant difference in numbers of physical illnesses, while numbers of therapeutic drugs for them were more in senile patients. CONCLUSIONS: Our study found significant differences between presenile and senile patients on psychiatric symptoms and diagnoses in geropsychiatric consultation. Therefore, more subdivided age-specific approach seems to be needed for the geropsychiatric consultation activities.

BACKGROUND: To evaluate the clinical and functional outcomes of arthroscopic-assisted reduction and percutaneous screw fixation for glenoid fractures with scapular extension, and investigate the radiologic and clinical benefits from the results. METHODS: We evaluated patients treated with arthroscopic-assisted reduction and percutaneous screw fixation for glenoid fractures with scapular extension from November 2008 to September 2015. Fractures with displacement exceeding one-fourth of the anterior-articular surface or more than one-third of the posterior-articular surface in radiographic images were treated by surgery. Clinical assessment was conducted based on range of motion, Rowe score, and Constant score of injured arm and uninjured arm at last follow-up. RESULTS: Fifteen patients with Ideberg classification grade III, IV, and V glenoid fracture who underwent arthroscopic-assisted reduction using percutaneous screw fixation were retrospectively enrolled. There were no differences in clinical outcomes at final follow-up compared to uninjured arm. Bone union was seen in all cases within five months, and the average time to bone union was 15.2 weeks. Ankylosis in one case was observed as a postoperative complication, but the symptoms improved in response to physical therapy for six months. There was no failure of fixation and neurovascular complication. CONCLUSIONS: We identified acceptable results upon radiological and clinical assessment for the arthroscopic-assisted reduction and percutaneous fixation. For this reason, we believe the method is favorable for the treatment of Ideberg type III, IV, and V glenoid fractures. Restoration of the articular surface is considered to be more important than reduction of fractures reduction of the scapula body.
