Measurements of mitral flow velocity by pulsed Doppler echocardiography are very useful in evaluating left ventricular diastolic filling properties. In hypertensive patients, abnormalities of diastolic function may precede systolic abnormalities and may serve as a more sensitive marker of end organ damage. We estimated left ventricular nass by 2-D echo short axis area-length method and compared with peak mitral flow velocity in early diastole(PFVE)and during atrial systolic(PFVA). There was a significant increase of LV mass and LV mass indices in the hypertensive patients and PFVE/PFVA ratio was decreased in them. Aithough there was no relationship between blood pressure and PFVE/PFVA ratio, a significant relationship was demonstrated between LV mass index and PFVE/PFVA ratio in the hypertensive patients.

Periprosthetic fractures after total hip arthroplasty or hemiarthroplasty are an uncommon complication. These fractures have problems of fixation of fracture and stability of the femoral component. Ipsilateral femoral fractures after hip arthroplasty occurred in 14 cases (11 patients) out of 510 hip arthroplasties performed between January 1985 and May 1996. These fractures occurred at an average of 3 years and 6 months after primary hip arthroplasty. These fractures were classified by Johansson classification. Nine fractures were treated with plate and cerclage wires. Four fractures were treated with skeletal traction. Bone graft was applied to the fracture site in 9 fractures which were treated by open reduction and internal fixation with plate and cerclage wires. Average follow up period was 21 months. The results were as follows. 1. All but three of the fractures had been developed by low energy trauma. Seven patients had osteolytic lesion around femoral component. Of the seven patients who had osteolytic lesions, six patients had periprosthetic fractures which connected with osteolytic lesions. We think that osteolysis is one of the important factors of the periprosthetic fractures after hip arthroplasty. 2. Four cases were treated by skeletal traction. One case had malunion. Progressive subsidence of femoral component was noted after union of fracture in 3 cases. Therefore these periprosthetic fractures which had an osteolysis and subsidence preoperatively should be managed with operative methods. 3. Nine fractures which had treated with plates and autogenous bone graft showed good hip joint function with stable femoral component. We think that stabilization of periprosthetic fractures with plates and cerclage seemed to be a good method for femoral fractures after hip arthroplasty.

PURPOSE: To understand the normal endosonographic anatomy of the perianal spaces, and to evaluate the diagnostic efficacy and limitation of endorectal sonography(EUS), correlative study with MRI, cadaveric sectional image and cadaveric MRI were performed. MATERIALS AND METHODS: EUS images of the normal 6 perianal spaces (pelvirectal, ischiorectal, intersphincteric, subcutaneous, central, submucous space) which were bounded by internal and external anal sphincters, rectal wall and levator ani muscle were correlated with MRI in 10 normal persons, cadaveric sectional images and cadaveric MRI in 2 cadavers. RESULTS: Pelvirectal space located superior to levator ani muscle could be demonstrable only on anterior wall scan but could not be visualized on lateral or posterior wall scan on EUS. Five perianal spaces located inferior to levator ani muscle were well seen on anterior, lateral, and posterior wall EUS. MRI was superior to EUS in the evaluation of pelvirectal and ischiorectal spaces but equal or inferior to EUS in the evaluation of intersphincteric, subcutaneous, central and submucous spaces. CONCLUSION: EUS was valuable in the evaluation of perianal spaces inferior to levator ani muscle but was limited in the evaluation of perianal spaces superior to levator ani muscle.

OBJECTIVE: The purpose of this study was to describe the MR imaging appearance of the dural ligaments which is connected between the anterior dura mater and the posterior longitudinal ligament. MATERIALS AND METHODS: In 10 cadavers with formalin fixation, the dural ligaments were evaluated and photographed after removal of the posterior element of the spinal canal. MR studies of 12 patients who had distinct dural ligaments were evaluated. Spin-echo MR images were obtained on a 1. 5T unit. RESULTS: In seven of the ten cadavers, the midline dural ligament was observed; the lateral dural ligament was observed in 3 cadavers. On MR, the dural ligaments were imaged as thin lines of low signal intensity between the anterior dural margin and the posterior longitudinal ligament. Dural ligaments were well-visualized at the level of the lower lumbar spine which had a more prominent anterior epidural space than that of the upper level of the spine. Eight of 12 cases had well developed midline dural ligaments. Two cases showed distinct lateral dural ligaments and the remaining 2 cases had distinct midline and lateral dural ligaments. CONCLUSION: MR images of the dural ligament demonstrate a thin low signal line at the anterior epidural space.

The questions concerning storage temperature and storage duration of the fortified ophthalmic antibiotic solutions are raised. The aim of the current study is to evaluate the influence of fortified ophthalmic antibiotic solutions on its biological and physical properties according to the storage temperature and duration as time goes by. We examined the changes of pH, absorbance spectra, and anti-microbial activity of cefradine(63mg/ml)and gentamicin sulfate(13.6mg/ml) over a four-week period. The results were as follows: There was no difference between the potency of fortified GM solutions stored at 4 degrees C and that at 24 degrees C for 4 weeks. The cefradine stored 24 degrees C exhibited significant changes in both its tJotency and stability after ithe seventh day of storage. The cefradine stored at 4 degrees C exhibited changes in Its absorbance spectra day by day and potency after 14th day.

The purpose of this study is to know about the consumption patterns of functional foods and their associated factors for contributing to the promotion of healthiness on Gwangju residents. The results obtained are summarized as follows: in terms of age, 35.9% of men (n = 78) and 52.3% of women (n = 128) are found in the age range of 45~54 which comprises the highest portion of age distribution. 49.5% of subjects had college education or more. In the occupation category, 33.3% of the men had business job positions, and 39.8% of women were in the unemployed (housewife) category. Stress relief was the most important factor to maintain good health. 76.2% of the subjects have experience in consuming functional foods. The main reason for taking functional foods was to maintain health. Information and reliability of effectiveness were considered when selecting functional foods. Purchasing functional foods was motivated by family members, relatives, and/or the subjects themselves. Functional foods were mainly purchased from pharmacies or health food stores. Regular exercise, drinking, periodical medical checkups, and eating score all are taken into consideration with the consumption of functional foods.77.9% of subjects recognized functions for functional foods purchased. 18.8% of subjects experienced side effects after intaking functional food. Therefore, functional foods should be managed by the government and nutrition education for consumers should be required to encourage them to choose functional foods more satisfactorily and safely.

Traumatic hemoperitoneum can still induce high mortality and morbidity rates, despite current method of intensive management. This study was performed to identify the independent prognostic factors in patients with traumatic hemoperitoneum. Two hundred thirty-six patients who underwent emergency operations because of traumatic hemoperitoneum at the Department of Surgery, Dong Kang General Hospital, Ulsan, from January 1986 to June 1994, were entered into this retrospective study. One hundred eighty-six patients were male, and fifty were female. The median age of the patients was 34 years (2 to 77 years). The modes of trauma were 131 motor-vehicle accidents, 43 fall down injuries, 30 stab injuries, 23 assaults, and 9 others . The common sites of injury were lthe iver and the spleen, followed by the mesentery, the stomach, the small bowels, the large bowels, the pancreas, the kidney, the diaphragm, and the retroperitoneum in order of frequency. Prognostic variables were identified from the perioperative parameters by using a univariate analysis(student t- test, chi-square test), and independent prognostic factors were determined by a multivariate stepwise logistic regression analysis, using the SPSS Win. Ver.5.0 PC package program. Statistical significance was present for p < 0.05. The overall postoperative morbidity and mortality rates were 34.3% and 19%, respectively. By using univariate analysis, the amount of bleeding, transfusion, and the immediate post-operative blood pressure were identified as significant prognostic factors for morbidity. Also age over 50, accompanying brain injury, time interval (less than 3 hrs), the systolic blood pressure on arrival (less than 100 mmHg), trauma score (less than 10), grade of liver injury (greater than IV), great vascular injury, total amount of resuscitative fluid (more than 4,000cc), the total amount of transfusion (more than 10 units), and the immediate postoperative systolic blood pressure (less than 100 mmHg) were identified as significant factors for mortality. Multivariate analysis demonstrated the following important independent prognostic factors : the total amount of transfusion for morbidity and mortality, and the post-operative blood pressure and trauma score for mortality. Our results suggest that early massive resuscitation, early operation to minimize the total amount of blood loss, and intensive immediate postoperative care to maintain blood pressure, are of utmost importance in multiple trauma patients with hemoperitoneum.
