The retrospective study was taken to study the serum transaminase level and it's correlation with several symptoms in human rotavirus gastroenteritis. 494 children, who admitted to the Department of Pediatrics in Dae Dong Hospital from January 1991 to December 1991 with chief complaints of waterdy diarrhea were included in studies. The 1st stool specimen on admission was tested for rotavirus Ag by ELLSA method. and than serum transaminase were checked. The results are as follows: 1) The peak incidence being between 6 months to 2 years in both group, but higher incidence was noted in Non-HRV group. Males are more common than females by ratio of about 2:1. 2) The major symptoms in order of frequency was diarrhea>dehydration>vomiting>coughing>fever in HRV group, diarrhea>dehydration=vomiting>fever>coughing in Non-HRV group. The incidence of dehydration and coughing in HRV group were higher than in Non-HRV group. 3) AST & ALT elevation above the normal value were 83.2% (213/256), 52.0% (133/256) in HRV group and 45.3% (116/238), 22.3% (57/238) in Non-HRV group. AST & ALT were significantly increased in HRV group than Non-HRV group (AST: p<0.05, ALT: p<0.05). 4) Mean concentration of AST & ALT were 46. 82, 38.06 in HRV group and 29.06, 21.23 in Non-HRV group. Mcan concentration of AST & ALT were significantly increased in HRV group than Non-HRV group (AST: p <0.05, ALT: p<0.05). 5) Mild dehydration is relatively more common in both group. The frequency were 56.6% (145/256) in HRV group, 47.5% (113/238) in Non-HRV group. The degree of dehydration was not correlated with serum transaminase level at each group(HRV group: p>0.05, Non-HRV group: p>0.05). 6) Duration of diarrhea for 4-5 days & 1-3 days were relatively more common in HRV group than Non-HRV group. The frequency were 36.3% (93/256) in HRV group and 34.9% (83/268) in Non-HRV group. The degree of diarrhea were not correlated with serum transaminase level at each group (HRV group: p>0.05, Non-HRV group: p>0.05). 7) No fever or duration of fever for 1-2 days were relatively more common in both group. The frequency were 39.9% (102/256), 37.5% (96/256) in HRV group and 38.2% (91/238), 42.5% (101/238) in Non-HRV group. The degree of fever was not correlated with serum transaminase level in HRV group, but correlated with Non-HRV group (HRV group: p>0.05, Non-HRV group: p<0.05).

Purpose: : Nursing students’ academic immersion in their major field is very important in their learning activities. It is necessary to understand the effect of empathy ability and social responsibility on major immersion. This study was conducted to understand the effect of empathy ability and social responsibility of nursing students on their major immersion. Methods: : This is a descriptive research study in which a survey of 238 nursing students was analyzed using the SPSS/WIN 21.0 program. Results: : The results of this study were empathy and social responsibility (r=.472, p<.001), empathy and major Immersion (r=.289, p<.001), social responsibility, and major Immersion (r=.597, p<.001) was statistically positively correlated. The results of the factors affecting nursing students’ major immersion were academic performance (β=-.171, p<.001), internal factor in major selection (β=-.109, p=.030), major satisfaction (β=-.284, p<.001) and social responsibility (β=.452, p<.001) variables explained about 50.1% of the major immersion. Conclusion : Through the research results, it is meaningful that nursing students can increase their immersion in the whole body through improvement of departmental achievements, internal factors in major choice, major satisfaction, and social responsibility. Nevertheless, since this study is the result of a survey of nursing students in one area, there are limitations to the expansion of interpretation.

Embryonic stem (ES) cells have potential for use in evaluation of developmental toxicity because they are generated in large numbers and differentiate into three germ layers following formation of embryoid bodies (EBs). In earlier study, embryonic stem cell test (EST) was established for assessment of the embryotoxic potential of compounds. Using EBs indicating the onset of differentiation of mouse ES cells, many toxicologists have refined the developmental toxicity of a variety of compounds. However, due to some limitation of the EST method resulting from species-specific differences between humans and mouse, it is an incomplete approach. In this regard, we examined the effects of several developmental toxic chemicals on formation of EBs using human ES cells. Although human ES cells are fastidious in culture and differentiation, we concluded that the relevancy of our experimental method is more accurate than that of EST using mouse ES cells. These types of studies could extend our understanding of how human ES cells could be used for monitoring developmental toxicity and its relevance in relation to its differentiation progress. In addition, this concept will be used as a model system for screening for developmental toxicity of various chemicals. This article might update new information about the usage of embryonic stem cells in the context of their possible ability in the toxicological fields.

To delineate the coronary anatomy and left ventricular function during early myocardial infarction, coronary arteriography and left ventriculogrphy were performed, prospectively in 23(22%) of 105 patients who were admitted to the coronary care unit at Masan Koryo Hospital from June 1986 to June 1988 within 4 weeks after the onset of symptoms(medium:21 days, range:18 days to 25 days). 1) Among 23 patients, male is 20 patients and female is 3 patients. The ratio of male to female was 6.6:1. The mean age was 55.4+/-10.3 years(range:34-77 years). 2) Coronary artery narrowing state which related to myocardial infarction was as follows; 2 patients(7%) had normal, 1 patients(4%) had insignificant narrowing(below 50%) 5 patients(22%) had moderate narrowing(50-75%), 10 patients(43%) had severe narrowing(75-99%), 5 patients(22%) had complete occlusion(100%). 3) The range of coronary artery disease was as follows; 9 patients had one vessel disease, 10 patients had two vessel disease, 1 patients had three vessel disease, and ejection fraction had no significant difference among 3 groups but lowest in three vessel disease. Among 23 patients, 13 patients had anterior infarction, 10 patients had inferior infarction. 4) Left ventricular ejection fraction and multiple vessel disease had no significant difference between i) the young(under 45 years old) and the old(over 45 years old) age groups, ii) presence or non presence of previous angina, iii) Killip classification I, II and III, IV) anterior infarction and inferior infarction. 5) In left ventriculography, akinesis and dyskinesis were shown at similar ratio in anterior infarction and inferior infaraction. Dyskinesis was shown in 27% of patients who have 0-1 vessel disease, 50% of patients who have 2-3 vessel disease, 62% of patients who have collateral circulation, 26% of patients who dose not have collateral circulation. 6) Collateral circulation was found in 8 patients(35%). Age and left ventricular ejection fraction were high in patients without collateral circulation than with collateral circulation, but there is no significant difference and collateral circulation exists regardless of infarction site and range of coronary artery disease. 7) As for the complication of angiocardiography in this study, there was ventricular tachycardia in 3 patients(13%) without mortality. It is concluded that coronary arteriography can be safely performed in early stage after acute myocardial infarction. Also good prognosis is anticipated since three vessel disease and complete occlusion were low in acute myocardiaol infarction of Korean People. Since these are not much case performed study, however more study on this area is required.

Superior mesenteric artery syndrome (SMAS) is an uncommon disease resulting from compression of the third portion of the duodenum by the superior mesenteric artery. Typical symptoms of SMAS are anorexia, nausea, vomiting, early satiety, abdominal pain and postprandial fullness. The diagnosis requires radiologic studies in patients with symptoms suggestive of SMAS. Radiologic studies include upper gastrointestinal barium study, angiography, abdominal ultrasound, endoscopic ultrasound, computed tomography (CT), and magnetic resonance imaging. The SMA angle to the aorta is normally 45degrees (range, 38-56degrees), whereas in SMAS, that SMA angle is decreased to 6 to 25degrees. Additionally, the distance between the SMA and the aorta normally ranges from 10 to 20 mm, whereas in SMAS this distance is decreased to 2 to 8 mm. Recently SMAS diagnosis has been most commonly confirmed by CT. Therapy of SMAS includes weight gain to increase the aortomesenteric angle, but surgery is indicated in symptomatic patients when conservative management failed. To date, laparoscopic duodenojejunostomy seems to be a first-choice surgical options.

BACKGROUND: Single pass lead VDD pacing preserves atrioventricular synchrony with a single lead system which incorporates floating atrial electrodes. The objectives of this study were to measure whether different body postures and physical activities cause significant changes of the atrial electrogram amplitudes and to evaluate the effectiveness of its atrial sensing, ventricular sensing and pacing. METHOD: Prospective study was done in 7 patients with high degree AV block and normal sinus node function in whom a single lead VDD pacing system was implanted. The P wave amplitude was been measured in different condition during follow-up period. RESULTS: 1) During follow-up period, the P wave amplitude showed variation with changes in posture and respiration, but there was no consistent increase or decrease in amplitude. The lowest P wave amplitude was above the minimal atrial sensing value of 0.2 mV. 2) The percentage of atrial synchronous ventricular pacing recorded in Holter ECG and during Treadmill exercise test was more than 99%. 3) Atrial oversensing or VA cross sensing were not observed in any of the patients. CONCLUSIONS: Despite floating atrial electrode, the single pass lead VDD pacing maintains reliable atrial sensing and ventricular pacing in different body position and physical activity, so it may offer an excellent alternative in patients with high grade AV block and intact sinus node function.
