The purpose of the study was to find the sociopsychological factors predicting the intention of compliance with the dietary regimen in diabetes with a questionnaire. Data were collected from 282 adult noninsulin-dependent diabetics in Seoul, Kyoggida, and Kyongsangbukdo in Korea. Stepwise multiple regression analysis was conducted with predictor variables from theories of the Health Belief Model, Social Cognitive Model, The Theory of Reasoned Action, and Social Support. The behavioral intention of compliance with the prescribed diet was the independent variable. Subjects norm self-efficacy knowledge about diet therapy, outcome expectation, relationship with medical team, threat of deterioration of disease, and social support were the independent variables, The mean score of behavior intention was high ie 35.3 out to 42. Subjective norm and self-efficacy were the significant variables to predict the intention of dietary compliance. These variables comprised 39% of the common variance. To increase dietary compliance by influence of the referents and improve self-efficacy significant referents must be included and concrete and practical methods to follow the dietary regimen must be provided in nutrition education.

The purpose of this study was to find the sociopsychological factors influencing the compliance of dietary regimen in diabetes by using focus group interviews. The data were collected from fifty three diabetes patients in eleven focus groups from September 1997 to March, 1998 in Seoul and Suwon Korea. The interviews were tape-recorded and the contents of the interviews were analysed by researchers. The subjects knew the causes, complications, and therapies of diabetes although they were incorrect at times . Patients had a wide range of outcome expectations from very optimistic to pessimistic. They recognized diabetes as a disease which needs life-time care, and they though that good care could provide a normal life. One the other hand they thought diabetes could lead to death through complications, and cause financial problems as well as social isolation. As for self-efficacy they recognized the importance of compliance to diet regimen but they thought the diet therapy was very difficult and were not very willing to follow it. They felt medical professionals, especially doctors, were influential for the therapies. However they frequently felt counselling provided by doctors was insufficient in time and content and led to attitude problems. They felt support from families and others was often insufficient and inadequate. Nutrition education fostering outcome expectation, social support, and self-efficacy is needed to increased compliance. The most influential referents were medical professional including doctors, nurses, dieticians, so their role in diet therapy should by emphasized.

Epidural narcotics has been most widely used for the control of postoperative pain. However, patients have been treated insufficiently because of the fear of respiratory depression. Urinary retension, nausea and vomiting, pruritus are other complications of epidural narcotics. Epidural local anesthetics may be an alternative to epidural narcotics. But the duration of action is usually too short, although epinephrine can prolong the analgesic effect. Clonidine, an a2-adrenergic agonist has its own analgesic effect and can prolong the effects of epidurally administered drugs. Therefore epidural clonidine may be expected to lessen the requirement of epidural narcotics and hence reduce the complications of narcotics. 75 ug or 150ug of clonidine was added to 0.125% bupivacaine or 2 mg of morphine. 6ml of mixed solution was administered epidurally during and after operation for the control of pain following upper abdominal surgery. Clonidine caused increase in the analgesic duration of epidural bupivacaine and morphine. Clonidine also cause decrease in systolic pressure in dose-dependent manner, especially during anesthesia without significant alterations in heart rate. Clonidine may be an useful adjunct to epidural narcotics, provided the dosage is carefully titrated in the range of modest hemodynamic change.

Many young women suffer from premenstrual syndrome (PMS). The purpose of this study was to examine the effect of isoflavone on serum sex hormone and PMS during the luteal phase of the menstrual cycle. We investigated the incidence of PMS in 116 Korean female college students. The incidence of PMS was 19.8%. Among them, 9 PMS and 13 control were given 90 mg isoflavone per day during 2 menstrual cycles. The changes in anthropometric measurements, dietary intakes, serum parameters including sex hormones, and PMS symptoms were observed. Isoflavone supplementation did not affect anthropometric measurements. However, SBP and DBP were significantly decreased in control. Dietary intakes were not changed after supplementation of isoflavones. Serum SHBG was lower in PMS group than in control and significantly decreased in control with isoflavone supplementation. PMS symptoms such as backache, sweet, salty, and fatty food craving, coffee/tea drinking, and anxiety were significantly lessened. Based on these results, isoflavone supplementation may benefit young women by reducing some of PMS. Further studies of soy isoflavones effect on sex hormone and PMS may help to prepare for PMS management.

BACKGROUND AND OBJECTIVES: No existing device for cardiopulmonary resuscitation(CPR)isdesignedto exploit both the "cardiac pump" and the "thoracic pump" simultaneously. This study was designed to assess the hemodynamic effects of simultaneous sterno-thoracic CPR (SST-CPR) vs. standard CPR (S-CPR) using a mechanical resuscitator in a canine model of cardiac arrest. DEVICE DESCRIPTION: We have built a device that depresses the sternum and circumferentially constricts the thorax simultaneously. This device has two components. The first component is a piston, which depresses the sternum. The second is a circumferential strap that constricts the thorax as the piston is pushed down on the sternum. MATERIALS AND METHODS: Twelve domestic dogs were enrolled in this study. After catheterizations to measure pressures from the aorta and the right atrium, ventricular fibrillation was induced by passing AC current to the right ventricle. After 4 minutes of cardiac arrest, S-CPR and SST-CPR were performed alternatively. Aortic pressure, right atrial pressure, cardiac output, and end tidal CO2 were measured while each method of CPR was performing. RESULTS: SST-CPR resulted in significantly higher mean arterial pressure than S-CPR (68.9+/-16.1 vs 30.5+/-10.0 mmHg, p<0.01). SST-CPR could generate higher coronary perfusion pressure than S-CPR (47.0+/-11.4 vs 17.3+/-8.9 mmHg, p<0.01). End tidal CO2 tension was also higher during SST-CPR than S-CPR (11.6+/-6.1 vs 2.17+/-3.3 mmHg, p<0.01). CONCLUSION: Simultaneous sternothoracic cardiopulmonary resuscitation is a new method of cardiopulmonary resuscitation, which can generate better hemodynamic effects than standard cardiopulmonary resuscitation.

OBJECT: To gather information concerning ontogeny, the authors present the results of immunohistochemical stainings of neuronal and glial markers and the reverse transcriptase-prolongation chain reaction (RT-PCR) of nestin for three intraventricular tumors located around the foramen of Monro. METHODS: Seven cases of central neurocytomas(CN), three subependymomas(SE) and eight subependymal giant cell astrocytomas(SEGA), were included in this study. Antihuman monoclonal antibodies of synaptophysin(SNP)(DAKO, 1:20), chromogranin A(ChrA)(DAKO, 1:100), neuron specific enolase (NSE)(DAKO, 1:500) and nerve cell adhesion molecule(NCAM)(Zymed, 1:500) were utilized for neuronal markers and glial fibrillary acidic protein(GFAP)(DAKO, 1:300) functioned as a glial marker in immunohistochemical(IHC) stainings. Reverse transcriptase polymerase chain reaction(RT-PCR) for nestin was performed in all cases. RESULTS: For chromogranin A, positive reaction was found in three of the seven CN cases but none of the SE and SEGA cases. For IHC staining of synaptophysin, positive reaction was revealed in all CN cases but in none of the SE and SEGA cases. For NCAM, positive reaction was demonstrated in five of the eight SEGA cases and in all SE and CN cases. For NSE, positive reaction was exhibited in seven of the eight SEGA cases and in all SE and CN cases. Positive reactions for NSE and NCAM in the SEGA cases were manifested mainly in the cytoplasms of giant cells and their background. For IHC staining of GFAP, positive reaction was demonstrated in one of the seven CN cases, in three of the eight SEGA cases, and in all SE cases. RT-PCR product of nestin was expressed in two of the seven CN cases, in two of the three SE cases, and in one SEGA case. CONCLUSION: Many cells of CN, SE and SEGA, had expressed positive reactions for both neuronal and glial markers in IHC study and nestin in RT-PCR. It is suggested that origin cells of these tumors might express both neuronal and glial differentiation.

BACKGROUND: Iron deficiency anemia frequently occurs in adolescence because of accelerated physical growth in both boys and girls, and because of menstrual iron loss and dieting to avoid obesity in female teenagers. As little is known about iron deficiency in adolescents in Korea, this study was aimed at assessing the prevalence of iron deficiency and iron deficiency anemia (IDA) in apparently healthy Korean adolescents in relation to gender, physical development, and dietary habit. METHODS: With a questionnaire regarding their demographic characteristics, blood samples were obtained from apparently healthy students aged 10~18 years by venipuncture at Sept. and Oct. 1996. Hemoglobin (Hb), hematocrit, RBC indices, serum ferritin levels, iron and total iron-binding capacity (TIBC) were measured. RESULTS: A total of 1,164 students (M:F = 610:554) aged 10~18 years were included in this study. In boys, the mean Hb concentration increased with age from 13.3g/dL in the 10~12 years group to 15.3g/dL in the 17~18 years group. In girls, the mean Hb concentration was 13.2g/dL in the 10~12 years group, and 12.7g/dL in the 15~16 years group. In boys, iron deficiency prevalence was 5.6% in the 10~12 years group, 10.6% in the 13~16 years. In girls, the prevalence of anemia increased with age: 0.8% in the 10~12 years group; 5.5% in the 13~14 years group; 16.9% in the 15~16 years group; 19.7% in the 17~18 years group. Iron deficiency prevalence in girls was 9.2% in the 10~12 years group, 14.1%in the 13~14 years group, 22.6% in the 15~16 years group, and 30.7% in the 17~18 years group. The prevalence of IDA in girls was 0.8% in the 10~12 years group, 4.3% in the 13~14 years group, 7.3% in the 15~16 years group, and 13.1% in the 17~18 years group. On questionnaire, 19.5% of males and 40.0% of females usually missed one meal a day. The proportion of missed meals in girls increased with age. The proportions of Hb<12g/dL and ferritin<10ng/dL were significantly high in boys aged 10~14 years with vegetarian parents. The prevalence of anemia and iron deficiency in the students with menstruation was 14.9% and 21.6%, which was higher than the prevalence of 3.3% and 13.2% in those who did not have the menarche (P<0.001 and P<0.05, respectively). CONCLUSION: As the prevalence of iron deficiency and IDA were substantially greater than expected, studies of iron state in adolescent girls, especially middle to high school age, should be undertaken to assess iron deficiency. In addition, nutritional education for adolescents is warranted.

PURPOSE: Any battery impacted in the esophagus must be removed urgently because of the possibility of serious complications such as perforation, fistula, and mediastinitis. The use of endoscopic procedures was compared to find the most rapid, effective, and safe method to remove disk batteries. METHODS: The cases of 24 children (9 males, mean age, 1.5 years) that had accidentally ingested disk batteries were reviewed. The patients had visited the Department of Pediatrics, Kyungpook National University Hospital from July 1997 to June 2007 for the removal of disk batteries. Endoscopic removal was attempted using a retrieval net or a magnetic extractor with a balloon (condom). The procedure times for removing the ingested battery were compared. RESULTS: Children that ingested batteries with a larger diameter (20 mm) had a greater chance to have esophageal impaction with serious injury, such as esophageal mucosal necrosis or ulcers, as compared to the ingestion of smaller diameter batteries (10 mm) (p<0.01). Endoscopic removal of disk batteries was attempted either using a retrieval net in 10 children or by using a magnetic extractor with a balloon in 6 children. Endoscopic removal using a retrieval net was more effective (mean procedure time: 1.5 min) as compared to using a magnetic extractor with a balloon (mean procedure time: 3.3 min) (p<0.05). CONCLUSION: Both procedures, either using a retrieval net or a magnetic extractor with a balloon were effective in removing ingested disk batteries. Based on our experience, an endoscopic procedure using a retrieval net was a more effective method for foreign body removal.
