The purpose of this study was to test Interaction Model of Client Health Behavior(IMCHB) of Cox repeatedly and to determine the contributions of sociodemographic variables, health experiences, family functioning, intrinsic motivation, health perception, self esteem, to health behavior of highschool students. A convenient sample of 2nd grade highschool students(N=638) responded to self-report questionnaires. The IMCHB was then tested with data using SAS program by frequency, t-test, ANOVA, regression. The results were as follows 1. Health behaviors were found to be gender specific. 2. From the body's model, mother and students health affected health perception and self-esteem among a set of background variables. Health perception and self-esteem are related to health behaviors. 20% of the varience in body's health behavior are explained by health perception and self-esteem. 3. From the girls model, students health explained 13.3% of health perception varience and father's health explained 11.6% of self-esteem varience. 16% of health behavior varience are explained by health perception and self-esteem. The results indicated that there was a relatively poor fit of the IMCHB to the highschool students data. But further study using the IMCHB to define health outcome in student is needed to verify the linkage. The model generated in this study clarified the contribution of some factors such as parental and student's health status. The results also indicated that the schoolnurse has to develop the health care program for students and their parent with community resources to improve health perception and self-esteem of students for intervening health behavior of highschool students.

One of the patellar function is to protect the femoral condyle from direct blowing to knee, so it is known that ligament injuries of the knee are rare in the presence of patellar fracture. We experienced four cases of posterior cruciate ligament injury associated with patellar fracture. Unfortunately, three cases were initially neglected, and one case was identified by visualization on avulsed posterior tibial spine in plain X-ray film. We reviewed these cases and obtained several results as follows; 1. Among four cases, three cases(75%) are fractured at the lower pole of patella without displacement and one case is a longitudinal fracture. 2. We consider possible two mechanisms of this injury; first, in flexed knee, posteriorly directed force on the proximal tibia produces posterior cruciate ligament injury followed by avulsed fracture at the lower pole of patella. Second, by fall on a flexed knee, the load is sustained on the inferior pole of the patella first and continuously drives the tibia backwards producing posterior cruciate ligament injury. We recommend that all surgeon should be aware of possibility of the ligament injury in the presence of patellar fracture, especially in lower pole fracture.

Carotid endarterectomy is superior to medical treatment in preventing secondary stroke in patients with symptomatic high grade carotid stenosis. Transluminal angioplasty is a promising procedure as an alternative treatment for these patients. We report two cases of carotid angioplasty with Palmaz-Schatz stent in patients with carotid artery occlusive disease. One patient presented with decreased right visual acuity because of retinal arterial embolism. The angiogram demonstrated a discrete tight stenosis of right internal carotid artery carotid stenting with Palmaz-Schatz coronary stent was performed without any significant complications. The other patient presented with recurrent episodes of cerebral infarction, for which he had undergone left carotid erdarterectomy 3-years ago. The carotid angiogram demonstrated tight stenoses of both internal carotid arteries. Carotid artery stenting was performed at left and right internal carotid arteries without any complications. We suggest that stenting may be an effective and safe therapeutic alternative to surgical treatment in some selected patients with carotid artery occlusive disease.

BACKGROUND: Brief episode of coronary artery occlusion (i.e., ischemic preconditioning) makes the heart more resistant to injury from a subsequent ischemic insult. Although a great deal of effort has been made in studying ischemic preconditioning, the underlying mechanism of ischemic preconditioning and its effect on hypothermic insult has not been elucidated. This study was performed to see whether ischemic preconditioning protects against the depression of cardiac contractility induced by hypothermic cardioplegic arrest/reperfusion. And recently, adenosine was known to have some correlation with the mechanism of preconditioning. If so, does this effect remain after the blockade of adenosine receptor by 8-phenyl theophylline? METHOD: Twenty-four Sprague-Dawley rat weighed 250-350g were used and divided into three groups. Rat hearts were removed rapidly, and each isolated heart paced with a rate of 180/min was perused by modified Krebs-Hensleit buffer(KHB) solution on a Langendorff apparatus far an hour. After obtaining baseline data including left ventricular pressure(LVP), dp/dt, and coronary flow, cardiac arrest was induced by perfusion of 0degrees C crystalloid cardioplegic(St Thomas) solution. After that, all hearts were stored in the same St Thomas solution at salute temperature far 2 hours. In group I (control group), the hear was reperfused by KHB solution. In group II(preconditioning group), the heart was subjected to two 2-minute episode of global ischemia followed by 5 minute reperfusion with KHB solution(preconditioning) before cardiac arrest. In group III(phenyl theophylline group), the heart was subjected to preconditioning procedure and 8-phenyl theophylline at 10muM in concentration was added to KHB solution at time of reperfusion. Observing parameter was obtained in each group at 10, 20, 40 and 60 minutes after starting reperfusion and compared statistically by use of one way ANOVA test(STASTICA, release 4.5). P-value less than 0.05 was considered significant. RESULTS: Although depressed LVP, dp/dt, and Coronary flow were seen in all groups during the reperfusion period, the preconditioned group showed more effective recovery of LVP than that of the control group, especially at 10, 20 and 40 minutes(p<.05). We failed to demonstrate the difference between the phenyl theophylline group and the control group(p=NS). CONCLUSION: These results suggest that ischemic preconditioning has protective effect on recovery state of hypothermic cardioplegic arrest/reperfusion. Its protective effect was limited during early reperfusion stage and was blocked by adenosine blocker.
