It is Important to know the normal size, shape, and signal intensity of anterior cruciate ligament in the evaluation of knee injury Many studies have reported findings of tear or rupture as well as normal anatomy of these structure, especially with MR images. To our knowledge, there are few studies about normal structures of anterior cruciate ligament in MR images. The purpose of this study is to compare normal finding with tear of anterior cruciate ligament on MRI. Twenty-three cases with rupture of anterior cruciate ligament were evaluated on MRI, measuring the length, thickness, width of anterior cruciate ligament, and angles of anterior and posterior cruciate ligaments. Mean length, thickness, and width of anterior cruciate ligament in patients with rupture were 37.7±4.8mm, 9.0±1.2mm, 8.0±0.8mm, and mean angles of anterior cruciate ligament, and posterior cruciate ligament were 48.1±9.6˚, 118.8±13.1˚. Curvature ratio of posterior cruciate ligament was 0.25±0.09. The results showed significant differences between normal persons and patients with complete or partial rupture, and the mean angle and curvature ratio of posterior cruciate ligament which are known to related with indirect sign in tear of anterior cruciate ligament showed significant differences between ours and that of western countries. These results will be useful in the evaluation of patient wish rupture of anterior cruciate ligament, especially on MRI.

We have examined the comparative efficacy of small doses of intravenous urapidil and labetalol in blunting hemodynamic response to endotracheal intubation and surgical incision in 30 patients without cardiovascular diseases. After intravenous urapidil 0.2 mg/kg or labetalol 0.2 mg/kg anesthesia was induced with thiopental 5mg/kg. Endotracheal intubation was facilitated by vecuronium 0.15 mg/kg with priming principle and anesthesia was maintained with enflurane and nitrous oxide in oxygen. Systolic, diastolic and mean arterial pressure and heart rate were measured before administration of the drugs, 5 minute after administration, just prior to endotracheal intubation and 1, 3, 5, 10 minute after intubatin. Also the peak blood pressures and heart rate within 10 minutes after surgical incision were measured. Endotracheal intubation and surgical stimulation were associated with significant increases in blood pressures and heart rate in both urapidil and labetalol group. Comparison of the changes in systolic, diastolic, and mean artrial pressures and heart rate between urapidil and labetalol group showed no significant difference except peak systolic pressure after surgical incision. It is concluded that the pressor response to endotracheal intubation and surgical stimulation are not influenced significantly by urapidil 0.2 mg/kg or labetalol 0.2 mg/kg. However, urapidil and labetalol preloading may be similarly effective in the blunting of the increases in blood pressures with larger doses of the durgs during anesthetic induction.

Ultrasound is very useful in evaluation of obstructive jaundice. We retrospectively evaluated the useful findings of ultrasonography in differentiating benign extrahepatic duct obstruction from malignant diseases. Among the 36 patients, 25 patients were benign extrahepatic obstruction and 11 patients were malignant obstruction. The shapes of extrahepatic dilatation were classified into fustiform, meniscus, and abrupt cut off by bowel gas. The diameter, length, and bile duct wall-interface were compared between benign and malignant groups and serum bilirubin and alkaline phosphatase were also compared between two groups retrospectively. The results were as follows. The most common form of extrahepatic dilatation was meniscus(10 of 26 patients, 38%) in benign obstruction, and fusiform(8 of 11 patients, 73%) in malignant obstruction. No significant difference was noted in diameter, length, serum bilirubin, and alkaline phosphatase between benign and malignant groups. Only one case showed decreased bile duct wall-interface in benign obstruction, but loss or decrease of bile duct wall-interface were 8 patients in malignant obstruction. The combined findings of fusiform dilatation and loss of bile duct wall-interface in ultrasonography will be helpful in differential diagnosis of malignant extrahepatic bile obstruction from benign conditions.

Accurate staging of lung cancer is essential for defining operability, selecting treatment regimens, predicting survival, and reporting comparable end results. Revisions in stage grouping of the TNM subsets in the International System for Staging Lung Cancer have been adopted by the American Joint Committee on Cancer and the Union Internationale le Cancer at 1996. We compared the previous TNM systems with revised stage grouping rules, and tried to applicate the new size-criteria for metastatic lymph nodes in mediastinum. Twenty-two patients were undergone CT stagings by using three different systems of previous, revised, and modified TNM subsets. Ten patients showed different TNM stage by the revised stage grouping rules and seven patients were altered in lymph node stage by the new size-criteria. Recognition of revised stage grouping rules is very important for treatment plan and predicting the correct prognosis.

The blood supply and metabolism of malignant nodules are qualitatively and quantitatively different from those of most benign nodules. We evaluated the efficacy of dynamic CT for differentiation of benign malignant lesions. Thirty-six patients with malignant nodule(n=20), tuberculoma(n=7), and pneumonic consolidation(n=9) were evaluated by thin section dynamic CT. CT numbers of lesion and aorta were measured before enhancement, and 1 minute, and 3 minutes after enhancement. Malignant lesions(maximum, 31.1±10.7 HU) enhanced significantly more than tuberculoma(maximum, 13.5±12.9 HU), but mass/aorta ratios were not so significantly different between malignant lesions(maximum, 0.61±0.27), tuberculoma(maximum, 0.36±0.15), and pneumonic consolidation(maximum,0.49±0.14). Dynamic CT is very useful for differentiation of malignant lesions from tuberculoma.

Purpose : This study was done to examine the relationship of health behavior, loneliness and self-esteem in elderly people. The results will contribute to the promotion of quality of life for elderly people. Method : The participants, 135 people over 60 years of age, were interviewed during January and February 2004. A questionnaire was used to collect the data. The measurement tools were the Loneliness scale developed by Kim (1997), the Self-esteem scale developed by Rosenberg and translated by Jeon (1974), the Health behavior assessment developed by Choi and Kim (1997). The data were analyzed using descriptive statistics, t-test, Pearson's correlation coefficients ANOVA, and multiple regression analysis. Result : The results of this study are as follows : Family type had a statistically significant correlation with health behavior, loneliness, and self-esteem in elderly people. Monthly income had a statistically significant correlation with health behavior in elderly people. Perceived health status had a statistically significant correlation with health behavior, loneliness and self-esteem in elderly people. There was a significant correlation between loneliness and self-esteem (r=-.531, p<.001), loneliness and health behavior (r=-.623, p<.001), and health behavior and self-esteem (r= .500, p<.001). Stepwise multiple regression analysis revealed that the predicting factors of health behavior were loneliness (38.8%) and self-esteem (4%). Conclusion : In conclusion, there exists a close correlation between loneliness, self-esteem, and health behavior. Especially, loneliness influences not only self-esteem but also health behavior in elderly people. The mediation of loneliness is a necessity for the improvement of physical and psychological health behavior.
