A clinical study was made on 47 cases of undescended testes during 9 years, from March 1973 to February 1982. The results obtained as follows: 1. The age distribution varies from 3 to 35 and 12 cases (26%) were between 21-25 years old. 2. Bilateral undescended testes were found in 8 cases, and in the cases of unilateral, right in 27 cases and left in 12 cases. 3. Of the 57 undescended testes, most popular location was inguinal type in 31 testes. (56.4%). 4. Hormonal therapy was done on 11 cases and among them only 2 cases of unilateral type responded with partial descent. 5. Orchiopexy was performed on 45 cases and orchiectomy on 2 cases. 6. Of the several methods of orchiopexy, dartos pouch method revealed high success rate (91%).

Blunt chest trauma to the heart may produce instantaneous death or, more frequently, congestive heart failure due to myocardial injury or disruption of intracardiac structures. Cardiac injury following by blunt chest trauma is often unsuspected and can range from cardiac contusion to chamber rupture, or to valvular dysfunction. The rate of occurrence of acute traumatic valvular insufficiency is extremely rare. Especially, the tricuspid valve is very rarely injured. Although clinical diagnosis of acute traumatic valvular insufficiency can be difficult to make for trauma patients with multiple injuries, echocardiography can establish diagnosis quickly and accurately. This report describes a patient who developed tricuspid regurgitation and acute heart failure following by an MCV.

The nonstructural protein NSP4, encoded by gene 10 of rotavirus, has been shown to play a role in viral assembly and known to be an enterotoxin, causing diarrhea in mouse pups. NSP4 gene was cloned from CBNU-2 (virulent bovine rotavirus/diarrheic fecal sample) and CBNU-1 (cell-culture adapted bovine rotavirus/isolated from CBNU-2 and 75 times passaged on MA104 cells), respectively, by reverse transcriptase-polymerase chain reaction (RT-PCR) and sequenced and compared. The sequence data indicated that the NSP4 genes of bovine rotavirus (BRV) were 751 bases in length and encoded one open reading frame of 175 amino acids beginning at base 42 and terminating at base 570. Differences in nucleotide sequence between CBNU-2 and CBNU-1 were observed at 6 positions (base 274, 296, 391, 394, 396 and 579). NSP4 gene of BRV exhibited a high degree of nucleotide (90% and 94%) and amino acid sequence (91% and 94%) and amino acid sequence (91% and 97%) homology with those of SA11 and UK but a low degree of nucleotide (77% and 79%) and amino acids sequence (81% and 85%) homology with those of Wa and OSU.

PURPOSE: This study investigated the effect of transformational leadership and individual characteristics on nurses' job involvement. METHOD: The sample for this study consisted of 594 nurses from 8 large Korean hospitals. The factor analysis was drawn from the Cronbach's alpha analysis, the Pearson correlation analysis, the multiple regression analysis, and the hierarchical multiple regression analysis. Result: This study found that; (1) charisma dimension of transformational leadership has positive influence on job involvement; but intellectual stimulation and individualized consideration did not showed significant effects on job involvement (2) nurse individual characteristics (age, marital status, educational level, tenure, position) moderated the effect of transformational leadership on job involvement. Conclusion : Therefore, to improve job involvement nurses are required to apply the charisma dimension of transformational leadership in hospital organization.

BACKGROUND: Spontaneous echo contrast(SEC) is known to predict the increased incidence of thromboembolism in a variety of heart diseases. Transesophageal echocardiography can be useful for the detection of SEC due to proximity of the probe to the left atrium. We performed this study (1) to evaluate the incidence of SEC in mitral stenosis and its relation to the past history of thromboembolism and (2) to characterize the echocardiographic and hemodynamic indices in patients with SEC compared with those without SEC. METHODS: Transesophageal and thransthoracic echocardiographies were done in 89 patients with mitral stenosis. Biplane probe was used in transesophageal echocardiography. In 47patients cardiac catheterization and angiography were performed. RESULTS: (1) SEC was found in 56 out of 89 patients(63%), and left atrial thrombus was found in 32 patients. (2) Left atrial dimension was larger in patients with SEC than in patients without SEC(57.3%+/-8.4mm vs 49.3+/-6.8mm, p<0.05) and mitrial valve area was smaller in patients with SEC than in patients without SEC(0.85+/-0.27cm2 vs 0.97+/-0.24cm2) (3) Association of SEC to thrombi or previous history of arterial embolism showed a high sensitivity and negative predictive value. CONCLUSION: SEC was an useful finding to predict the increased risk of thromboembolism in patients with mitral stenosis. Patients with SEC had severe mitral stenosis than patients without SEC.
