2.AgNOR Counts in S-phase Human Cells.
Korean Journal of Pathology 1999;33(2):103-107
The nucleolus of human cell is a morphologically well recognizable nuclear organelle and the argyrophilic NORs (AgNORs) are nucleic acid-argyrophilic nonhistone protein complex in the nucleoli and the silver staining allows their identification and enumeration at the light microscopic level. The AgNOR counts are in parallel with mitotic activity and vary in different phase of cell cycle. It has been reported that human cells have one AgNOR during interphase and S-phase. However, the correlation between the number of AgNORs and S-phase markers is still controversial and they have never been studied simultaneously. In this study, AgNOR and PCNA were stained simultaneously to find out the relationship of AgNOR counts with cell cycle (S-phase) in human palatine tonsil, gastric carcinoma, liver and brain tissues. S-phase cells (PCNA-positive) were found predominantly in lymphoid follicles in palatine tonsil but gastric carcinoma showed diffuse immunoreactivity for PCNA. The AgNOR counts varied according to the type and locus of tissue. More than one AgNOR were identified in S-phase cells and some of hepatocytes and neurons in the brain which were not in S-phase contained two or more AgNORs. The above results suggest that the number of AgNOR is a characteristic feature of each type of cells and can be more than one even in S-phase.

The carpal tunnel syndromes is one of the most common peripheral nerve entrapment syndromes. The typical symptoms are pain, numbness and paresthesia in the median nerve territory of the hand. Recently, it is widely recognized that occupational factor is regarded as the important cause of the carpal tunnel syndrome. Clinical study is performed in the 42 female workers who is repetitively working at packing department in a rayon manufacturing factory from November 1991 till March 1992. The study included a questionnaire, physical examinations, and the neurophysiological test. The summary of the results obtained was as follows: 1. Among 42 packing workers, 9 workers(21.4%) were diagnosed as carpal tunnel syndrome by electromyography. The affected side was bilateral in 4 workers(9.5%), right in 4 workers(9.5%), and left in one worker(2.4%). 2. Among 42 subjects, 28 workers(66.7%) complained the clinical symptoms related to carpal tunnel syndrome, 11 workers(26.2%) showed positive Phalen sign, and 7 workers(16.7%) showed positive Tinel sign. 3. Researchers regard electromyographic finding as the gold standard for diagnosis of carpal tunnel syndrome. The sensitivity and specificity of the clinical symptoms to diagnose the carpal tunnel syndrome were 0.89, 0.39 respectively. If the carpal tunnel syndrome is diagnosed by the combination of the positive findings of the symptoms and the physical examinations, either Tinel of Phalen sign, the sensitivity and specificity were 0.67 and 0.76 respectively. Considering above results, though this small number of worker is not adequate for epidemiologic conclusions, carpal tunnel syndrome seems to be an important occupational disorder among packing workers in a rayon manufacturing factory.

Fifty three surgically resected gallbladders(49 cases of chronic cholecystitis with or without cholelithiasis, 4 cases of incidentally resected gallbladders) and 14 autopsy cases were subjected to the histotopographic analysis to identify the nature and distribution of metaplastic mucosal changes, and to determine the possible histogenesis of these mucosal lesions and diagnostic implication as a parameter of chronic cholecystitis. 1) Antral type glands were demonstrated in 47(88.7%), goblet cells in 19(35.8%) and surface epithelial changes in 27(50.9%) of total surgical specimens, indicating the benign metaplastic changes of the gallbladder mucosa toward the gastric or intestinal type. 2) Topographic distribution illustrated the extension of antral type gland to the middle and upper one third portions of the gallbladder mucosa in 37 cases, each. Goblet cells in the middle and upper one third of the mucosa were demonstrable in 13 cases(68%) an 8 cases(42%), respectively. 3) Average age by degree of extension was 50.0 years in Grade O-I, 50.1 years in Grade II and 56.4 years in Grade III. 4) Among 53 surgically resected gallbladders, gallstone was found in 31 cases, in which was a significant correlation between the distribution of metaplastic changes by degree of extent and cholelithiasis. 5) There was no statistical significance between incidence of metaplastic changes of the gallbladder and degree of inflammatory reaction by means of chronic and/or acute inflammatory cell infiltration and Rokitansky-Aschoff sinus formation. 6) Only two out of fourteen autopsy cases demonstrated focal and spotty presence of goblect cells. It is of authors assumption that the lining epithelium of the gallbladder undergos various types of metaplastic changes in the diseased conditions, in which cholelithiasis is included as one of preceding factor. And also, the diagnostic implication of epithelial metaplasia as an expression of chronic cholecystitis is discussed.

A case of osteold osteoma was presented because of its rarity in number particularly in localization of tumor, that is, subperiosteal in position. Also we could treat the patient successfully by surgical intervention and the removed specimen preserved beautifully all the character and contour of the tumor grossly and microsoopically.

The Journal of the Korean Orthopaedic Association 1970;5(2):49-54
This is to present 44 cases of hip fractures, of these 28 being fractures of femoral neck and the remainder, intertrochanteric, which were treated at the Department of Orthopedic Surgery, Seoul National University Hospital for four years and 8 months from Jan. 1965 to Aug. 1969. 1. There were 33 males. and 11 females in the series. 26 cases(59.1) were over 51 years of age. 2. The femoral neck fractures were treated by means of Smith Petersen nailing in 16 cases, modified Girdlestone hip arthroplasty in 3 cases, Austin-Moore hip prosthesis in 6 cases and other methods in 3 cases. 3. Modified Girdlestone hip arthroplasty could be a treatment of choice for femoral neck fracture requiring hip arthroplasty for those unsuitable for extensive surgery. 4. The intertrochanteric fractures of femur except for 3 unstable fractures were treated successfully with the Smith-Petersen nail and plate, following anatomical reduction of fracture. In 3 unstable fractures, satisfactory stabilization and internal fixation was obtained by the method of medial displacement of proximal part of distal fragment of fracture.

The cardiovascular manifestations in hyperthyroidism are sinus tachycardia, paroxysmal supraventricular tachycardia, atrial flutter, atrial fibrillation, atrioventricular block, bundle branch block(especially right bundle branch block), angina pectoris, heart failure and cardiomyopathy. Of these, angina pectoris is commonly seen in hyperthyroidism with coronary artery disease and the potential mechanisms have been attributed to the increased metabolic demand and consequently increased cardiac work which result in the more demand of coronary blood flow than that can be delivered via a fixed atherosclerotic coronary artery stenosis. Hyperthyroidism associated anginas without underlying coronary artery stenosis have also been reported where the mechanism of these was suspected to be the coronary vasospasm. Ventricular fibrillation may occur in the thyrotoxic patients due to myocardial ischemia such as variant angina, but it is very rare in the condition without previous heart disease. A 30-year-old male was admitted to the hospital because of palpitation, weight loss and proptosis for the previous 3 months. There was no history of effort related chest pain, syncope, drug abuse or medical illnesses such as diabetes mellitus, hypertension. The laboratory results were, TSH: 0.38uU/mL(0.4~5,0 uU/mL), free T4: 8.9ng/dL(0.8~1.9ng/dL), TSH receptor antibody: 43.6%(-15~15%), antiTPO antibody: 5000 IU/mL(0~100 IU/mL). The initial EKG showed normal sinus rhythm. He was diagnosed as Graves disease with ophthalmopathy, class 3a and was put on propylthiouracil 200 mg po tid, propanolol 40 mg po tid and started solumedrol pulse therapy for the exophthalmos on the first day of admission. He was found to have generalized tonic seizure with apnea attack on second hospital day and twice thereafter. Ventricular fibrillation was documented at that time. DC cardioversion was performed with successful response. After the attack, he was treated as accelerated hyperthyroidism namely with increased dosage of propylthiouracil, dexamethasone and Lugols solution, The echocardiogram, treadmill test, ergonovine echocardiography, coronary angiography and electrophysiologic study disclosed no abnormalities. Further episodes of ventricular fibrillation didnt occur after being euthyroid state. In conclusion, we report a case of ventricular fibrillation associated with hyperthyroidism itself without underlying coronary artery disease with brief review of literatures.
