In the operation room of S.N.U.H., 10 patients were transfused with A,C.D. stored blood after warming to 36 degrees C by using a blood warmer. Observed changes of Na+, Cl-, K+ and. Ca++ were as follows. 1) Before warming, the electrolytes of A.C.D. stored blood were Na+ 148. 2 mEq/1, Cl-; 117. 0 mEq/1 and K+; 8. 4 mEq/l. After warming to 36C, these were significantly reduced(P <0. 05) and became 144. 6mEq/1, 112. 4mEg/1 and 68. 13mEq/1 respectively. 2) There was a tendency to increasing of K+ cencentration in proportion to storage duration. 3) In the case of calcium, pre-warmed concentration of calcium was 4. 09 mEq/1 and there was no significant change after warming(P>0.05).

The ulcerative colitis is a relatively common disease in the European and North American countries aince Dr. Wilks has first reported the cases in 1895, But in Korea, this disease is a rare entity and only a few case have been reported. However, rescently the diagnoetic methods for ulcerative colitis are much developed we have experienced 28 cases of ulcerative colitis which were diagnosed by endoscopy, barium enema exam and biopsy. Therefore a total of 28 patient with ulcerative colitis diagnosed and treated at the department of internal medicine of HYUH from June 1979 to June 1986 was reviewed. We obtained the results as follows; 1) The sex distribution assumed a ratio of 1 to 1.33 with 12 males and 16 females. 2) The age dietribution was relatively even but the majority of cases were between 5th and 6th decade (32.1%), 3) The most prominent clinical symptoms were rectal bleeding, abdominal pain, diarrhea, fever, wight loss and vomiting. 4) Significant laboratory findins were anemia, eleveited ESR, leukocytosis, positive stool OB, electrolyte imbalance and decreased serum albumin level. 5) As to the extent of disease determined by the barium enema examination and endoscopic exam., rectum or rectosigmoid colon is involved in majority of the cases (92.8%). 6) The endoscopic examination was performed in all 28 cases and showed significant findings such as ulceration, hyperemia, mucosal friability, bleeding etcs. 7) The barium enema examination was performed in 19 cases and showed positive findings such as ulceration, luminal narrowing, bowel shortening and rigidity in 17 cases. 8) 21 of 28 patients treated by medical therapy showed relatively improved but 4 of 28 patients was exacerbated or relapsed and one has expired.

BACKGROUND AND OBJECTIVES: Telomeres are specialized structures found at the ends of eukaryotic chromosomes. Telomeres stabilize the chromosome and protect DNA from illegitimate recombination. Telomerase is a ribonucleoprotein, a RNA dependent DNA polymerase, and acts as a reverse transcriptase-like enzyme, which maintains telomere length by adding telomeric repeat units of TTAGGG to the telomeric end. These telomeric repeat units have been found only in cells with unlimited replicative potential such as sperm cells, immortalized cell lines and cancer tissues, but not in normal somatic cells. Telomerase is believed to be characteristic of and may be the best indicator of cell immortality. This study was performed to indentify the role of telomerase activity in the multistep carcinogenesis of oral squamous cell carcinoma. MATERIALS AND METHODS:We performed a telomeric repeat amplification protocol assay in 10 oral leukoplakia, 5 tongue cancers and 10 normal oral mucosa tissues. RESULTS: All the five tongue cancer tissues showed telomerase activity. Although telomerase activity was detected in 9 of 10 oral leukoplakia tissues and in 9 of 10 normal oral mucosa tissues, the activity of telomerase was low compared to that of cancer tissues by semiquantitative analysis. CONCLUSION: These findings suggest that telomerase maybe play a key role in multistep carcinogenesis of oral malignancy. Telomerase activity was detectable in normal oral mucosa with renewal activity suggested that this enzyme might be an indicator of cell proliferation.

BACKGROUND: Patency of the infarct-related coronary artery may influence LV remodeling, provide a more stable electrophysiologic milieu and improves the outcome of patient with acute myocardioal infarction. The result from clinical trials have confirmed that early reperfusion in humans induced by a thrombolytic agent is associated with limitation of infarct size, preservation of ventricular function, and improved survival. The purpose of this study was evaluate the effect of thrombolytic therapy on the severity of the residual stenosis, antegrade flow of infarct-related coronary artery after acute myocardial infarction, and investigate left ventricular function and regianal wall motion abnormality depending on the thrombolytic therapy. METHODS: A retrosperctive study was performed in 166 patients with acute myocardial infarction with underwent coronary angiography within 8 days after acute attack from Oct. 1990 to Sep. 1994. Patients were grouped as thrombolysis group(n=64) who had undertaken urokinase infusion therapy within 6 hours of symptom onset and conservatively treated group(n=102) who had not received thrombolytic trerapy. At 8+/-7days, cardiac catheterization was performed. Status of the infarct related artery was assessed by resiudal % diameter stenosis, TIMI and collateral trading. Left ventricular function and wall motion were analyzed. RESULTS: 1) The was no statistical differenccs in age, sex and risk factors(diabetes, hypertension, smoking and hypercholesterolemia)between two groups. 2) The peak serum CK level was higher(2719+/-2333 vs 1951+/-2064 IU/L) and time to peak CK enzyme level was shorter(19+/-13 vs 32+/-24 hr) in thrombolysis group than conservatively treated group. 3) There was lower incidence of total occlusion(12.5% vs 30.4%), residual % diameter stenosis of infarct-related artery(67+/-34% vs 80+/-27%) and better antegrade flow(TIMI grade 0-1, 12.5% vs 32.4%) in thrombolysis group than conservatively treated group(p<0.05). 4) There were no statistical differences of ejection fraction(51+/-15 vs 51+/-14%). left ventricular end diastolic pressure(21+/-10 vs 21+/-16mmHg) and regional wall motion score(8.6+/-3.4 vs 9.1+/-3.1) between thrombolysis group and conservatively treated group(p>0.05). CONCLUSION: Thrombolytic therapy in acute myocardial infarction resulted in dquisition of early infarct-related arterial patency, effectiove antegrade flow and reduced incidence of totoal occlusion of infarct-related artery. Left ventricular ejection fraciton, regional wall motion score was not affected by thrombolytioc therapy in inhospital period.
