Venous island flap has many advantages over other flaps, such as random pattern flap, island flap or free flap. It can cover the defect with wide arc of rotation and does not require vessel anastomosis and arterial pedicle, hence more sites are available for donor. The procedure is a time saving and simple procedure and can be performed even by two operating members. But it is not frequently used because of the poor survival of the flap. In this study, we attempted to allow whether pharmacological or delay procedure can enhance the survival of the venous island flap and the mechanism of the delay flap survival. We devised a model of venous island flap whose pedicle was a branch of central vein on the auricle of Newzeland white rabbit. SOD, allopurinol and SOD and allopurinol were given as pharmacological treatment and delay procedure was carried out to enhance the survival of the flap. For the study of survival mechanism of the delay flap, SOD levels of the delay and non-delay flap were observed by SOD 525 method. The results were as follows: 1. Allopurinol, SOD and, SOD and allopurinol improved the survival of the flap significantly. 2. Delay procedure improved the survival of the flap significantly. 3. The level of SOD in delay flap was higher than that of non-delay flap regardless of the site within the flap or time passage. In conclusion, it is inferred that the administration of allopurinol and SOD and surgical delay can enhance the survival of the venous island flap. In delay venous island flap, increased level of SOD within the flap seem to contribute to the increased survival of the flap.

This study was conducted to assess the referral patterns to specialist from general practitioners in health center and perceived needs of referred patients for specialist care in health center. The study subjects were 249 patients who visited to health centers and were referred to other medical facilities. The data were obtained from questionnaire survey which was conducted in Kyongjuu-city Health center, Seongju-Gun Health center and Koryong-Gun Health center in Kyongsangbuk-Do, from June 10 to october 17, 1995. The total referral rate was 2.7%. The proportion of patients who wished to be referred to medical specialists was 85.9%, and the proportion of patients referred by general practitioners in health centers was 14.1%. Among the patients who wished to be referred to medical specialists, 45.9% visited directly to health centers, 34.6% visited health centers via local clinics and 19.5% visited health centers to get referral permission only. The reasons for getting referral permission in health centers were easy geographical accessibility(34.6 %), easy to get referral permission in health centers(27.l%), and very difficult to get referral permission in local clinics(l6.4%). Among the diseases of referred patients, diseases of the musculoskeletal system and connective tissue were most prevalent on a whole, but diseases of nervous system and sensory organs were comparatively high among the patients who wished to be referred to medical specialists and infectious and parasitic diseases were comparatively high among the patients referred by general practitioners in health centers. The most favorable medical facility was general hospital including university hospital in both groups of patients who wished to be referred to medical specialist and the patient referred by general practitioners in health centers. Regarding the needs for specialist care in health center, 75.2% patients who wished to be referred to medical specialists and 74.3% of patients referred by general practitioners in health center wanted the specialist care. The most frequently requested speciality is internal medicine(47.1%), and then orthopedics and general surgery. Based on above results, this study revealed that the majority of patients referred from health center wished to be referred to medical specialists at their own will, so, referral system at health center level should be changed. And if specialist care in health center be provided, the medical care by internist could be provided first, and then that of orthopedics and general surgery could be provided. These kinds of medical cares could be covered by local clinicians as a part-time job on a voluntary basis.

BACKGROUND: Exercise has shown to slow down the progression from mild cognitive impairment (MCI) to dementia. In particular, not only resistance exercise has been verified to improve physical performance and muscle strength, leading to the prevention of fall-related injuries in the frail elderly, but also cognitive function. In this study, we investigated how high-speed elastic band training, applied using a high-speed power training protocol, affects cognition, physical performance and muscle strength of female elderly individuals with MCI. METHODS: Thirty-nine subjects diagnosed with MCI from one senior college using a Korean version of mini-mental state examination (MMSE-K) and a Korean version of the Montreal Cognitive Assessment (MoCA-K) were randomly divided into exercise group (n=20) and control group (n=19). The exercise group completed a 12-week high-speed resistance elastic band exercise program and was encouraged to exercise at home as well during the intervention period. RESULTS: The results showed significant increases in cognitive function, physical performance and muscle strength assessed by digit span forward test (P<0.001), digit span backward test (P=0.003), the Stroop test B (P=0.031), SPPB scores (P=0.010), right knee 60degrees extensor peak torque (P=0.004), 60degrees flexor peak torque (P=0.001), 180degrees extensor peak torque (P=0.020) and grip strength (P=0.025). CONCLUSIONS: Our study showed that participants with MCI who continued the high-speed elastic band training program for 12 weeks showed improvements in cognitive function, physical performance and muscle strength.

The incidence of adenocarcinoma of the uterine cervix had shown an increasing tendency, and which is related to the increased use of oral contraceptives or prevalent in human papillomavirus infection. Endocervical glandular dysplasia or adenocarcinoma in situ are occasionally associated with squamous neoplasms of the uterine cervix. This study was aimed to evaluate the histologic features and the incidence of endocervical glandular lesions associated with squamous neoplasms, the presence of human papillomavirus infection-suggesting histologic findings in adjacent squamous neoplasms and the immmunohistochemical findings of endocervical glandular lesions for carcinoembryonic antigen. The materials used were 105 cases of microinvasive and invasive squamous cell carcinoma, and 83 cases of squamous intraepithelial lesions which are consisted of 142 radical or total hystrectomy products and 46 conization or loop excision products. The results are as follows; 1. Among 188 cases, six cases(3.2%) had shown foci of high grade glandular dyaplasia, and 19 cases(10.1%) revealed the areas of low grade glandular dysplasia. There was no adenocarcinoma in situ case. 2. In four of six high grade glandular dysplasia cases, microinvasive or invasive squamous cell carcinomas were associated. In low grade glandular dysplasias, sqaumous intraepithelial lesions were occcupying 68.4%. 3. HPV infection-suggesting histologic findings had accompanied all high grade glandular dysplasia cases and in 17 cases(89.5%) of 19 low grade glandular dysplasias. 4. In 2 of 5 high grade glandular dysplasias and in 1 of 19 low grade glandular dysplasias, the immunohistochemical reaction for carcinoembryonic antigen was similar to that of adenocarcinoma. In conclusion, the clinicopathologic importance of endocervical glandular lesions associated with squamous neoplasms of the uterine cervix should be kept in mind, and further study for the relationship between endocervical glandular lesions and human papillomavirus infection or hormonal influence will be continued.

This study was conducted to assess the effects of implementation of the patient referral system started July 1st, 1989. A comparison on the pattern of outpatient services of the Departments of Internal Medicine, General Surgery, and Pediatrics at the Yeungnam University Hospital was conducted for each one year period before and after implementation of the patient referral system. The pre-implementation period was from July 1. 1988 to June 30, 1989 and the post-implementation period was from July 1. 1989 to June 30, 1990. The information used for this study was obtained from official forms, prepared by the Yeungnam University Hospital, and submitted to the Korean Medical Insurance Cooperatives. After implementation of the patient referral system, the number of outpatient cases in the Department of Internal Medicine decreased 36.1% from 9,669 cases to 6,181 cases a year. Cases in the Department of General Surgery decreased 23.7% from 1,864 cases to 1,422 cases a year. The number of cases in the Department of General Surgery decreased 23.7% from 1,864 cases to 1,422 cases a year. The number of cases in the Department of Pediatrics decreased 36.9% from 3,372 cases to 2,128 cases a year. After implementation of the patient referral system, the average age of cases in the Departments of Internal Medicine and General Surgery was 52.5 and 49.7 years old, respcetively. This was a significant increase in comparison with the pre-implementation period. After implementation of patient referral system, the proportion of new outpatients in the Department of Internal Medicine decreased form 24.1% to 14.6%, the Department of General Surgery from 36.0% to 23.4%, and the Department of Pediatrics from 15.5% to 8.3%. The number of visits per case decreased significantly in the Department of Internal Medicine(from 1.74 to 1.61), but there was no significant change in the Department of General Surgery and Pediatrics. The length of treatment per case increased significantly in all three departments (form 16.1 days to 19.3 days in the Department of Internal Medicine, from 12.0 days to 15.2 days in the Department General Surgery, and 8.9 days to 11.2 days in the Department of Pediatrics). The number of clinical tests per case increased significantly in the Department of Internal Medicine (from 22. to 2.5), in the Department of Pediatrics(from 0.8 to 1.1) and increased in the Department of General Surgery(from 6.4 to 6.6). The average medical cost per case decreased form 43,900 Won to 42,500 Won in the Department of Internal Medicine, while the cost increased from 75,900 Won to 78,500 Won in the Department of General Surgery and from 12,700 Won to 13,500 Won in the Department of Pediatrics. In case-mix, the chronic degenerative disease(i. e. hypertension, diabetes mellitus, angina pectoris, malignant neoplasm, and pulmonary tuberculosis) ranked higher and acute infectious diseases and simple cases(i. e. gastritis and duodenitis, haemorrhoids, anal fissure, carbuncle, acute URI, and bronchitis) ranked lower after implementation of the patient referral system compared to before implementation.
