Tetralogy of Fallot constitutes the highest proportion of cyanotic congenital heart disease and has four basic abnormal anatomical pictures including ventricular septal defect, pulmonary stenosis, aortic overriding and right ventricular hypertrophy. The work of Edward, et al(1965), Guntheroth, et al(1965) and Lev and Eckner(1964) has shown that the anatomical picture in a combination of just first two morphological characteristics, the aortic overriding and right ventricular hypertrophy being a consequence of the ventricular septal defect and pulmonary stenosis. Basic signs involve two categories, one is change of shunt rate depending on pulmonary stenosis, ventricular septal defect and systemic vascular resistance, and the other is physiological response to the chronically lowered PaO2. Thus the pathophysiological status presents to us more problems than other congenital heart disease in the care of patients during operation and anesthesia. Therefore, the anesthesiologist must understand the basic pathophysiology, various findings of examination, symptoms and signs, the problems during anesthesia and postoperative care. The purpose of this study was to evaluate the anesthetic management in total corrective surgery of tetralogy of Fallo which was performed at Severance Hospital. Out of consecutive 160 cases of tetralogy of Fallot in our past ten years experiences from 1971 to 1980, we selected the clinical results on anesthetic care of 12 cases which received total corrective surgery under hypothermia and extracorporeal circulation. The results were as follows: 1) Out of 121 cases, 82 cases were male(67.8%) and female was 39 cases(32.2%). The group aging from 6 to 10 year old was the highest proportion (44.6%) and the next proportion was the group aging from 11 to 15(22.3%). 2) Out of 121 cases, 91 cases were cyanotic(75.2%). On the diagnostic distribution, tetralogy of Fallot without any other anomaly was the most common(66.9%). 3) As for premedicants, secobarbital was the highest proportion(28.1%). For anesthetic maintenance, methoxyflurane with nitrous oxide was the most common(43.8%). 4) During cardio-pulmonary bypass, high flow perfusion was commonly used and the highest mean arterial pressure was 89.09+/-1.21 mmHg and the lowest mean arterial pressure was 36.33+/-1.21mmHg. 5) The major complications after operation and anesthesia were dysrhythmia(13.1%), pleural effusion(10.3%), main wound infection(10.3%), hemorrhage(8.3%), acute renal failure(8.3%), heart failure(6.9%), low output syndrome(4.1%) and cerebral infarction due to air emboliam(2.7%). 6) Out of 121 cases were expired and hospital mortality was 23.1%. The causes of death were heart failure(50%), acute renal failure(14.3%) and cerebral infarction(14.3%). in conclusion, anesthetic care for total corrective surgery of teralogy of Fallot should be based upon the understanding of the pathophysiology of disorder itself.

Postoperative muscle pain is well known to occur in man following intravenous administration of succinylcholine. The mechanism of muscle pain is yet unknown. A number of methods for preventing muscle pains or decreasing their severity have been suggested, including nondepolarizing relaxants prior to succinylcholine (Churchill-Davidson, 1954: Cullen, 1971: Wig and Bali, 1979) or lidocaine(Usubiaga et al., 1967: Haldia et al., 1973: Fry, 1975), use of vitamin C (Gupte & Savant, 1971), procaine chloride(Morris & Dunn, 1957), thiopental sodium (Craign, 1964) or diazepam (Verma et al., 1978) and the use of a "self-taming" method of succinylcholine by prior injection of a small dose(Baraka, 1977). To investigate methods of preventing muscle pains or decreasing their severity after intravenous injection of succinylcholine, we studied four groups, a control group and three experimental groups (a lidocaine group, a d- Tubocurarine group and a succinylcholine self-taming group). The following results were obtained: 1) In the lidocaine group, the incidence of muscle pain was lower than in the control group, but there was no significant difference between the two groups. However the incidence of muscle pain in the d-Tubocurarine group or the succinylcholine self-taming group were lower than in the control group and there were statistically significant differences(p<0.0005). 2) In most of the patients of each group, the degree of postoperative muscle pain was mild and a difference of degree of muscle pain was not found in each group (p>0.05).3) The muscle pain usually appeared in the first day after operation and disappeared usually within three days. 4) The degree of muscle fasciculation showed a significant decrease with lidocaine, d-Tubocurarine or the succinylcholine self-taming group over the control group(p<0.0005), but there was no significant relationship between the degree of muscle fasciculation and the incidence of postoperative muscle pain(p>0.05). 5) The degree of muscle relaxation during intubation in the d-Tubocurarine group was less complete than in the other 3 groups and it was statistically significant(Zi>1.96). It is suggested from the above results that d-Tubocurarine(0.05~0.06mg/kg) prior to succinylcholine or the method of self-taming of succinylcholine(prior use of succinylcholine 0.15mg/kg) can be used as methods to prevent muscle pain after intravenous administration of succinylcholine, but lidocaine(2mg/kg) prior to succinylcholine is not effective in preventing muscle pain following succinylcholine administration.

At present, spinal anesthesia is often recommanded for a safe operation and the management of pain. However the complications from the spinal anesthesia, such as hypotension, dyspnes, nauses and vomiting, pulmonary embolism, headache, auditory and visual disturbances, lumbago, urinary difficulty and neurologic sequelae have often reported from time to time. Thus an attempt to study the complications of spinal anesthesia, particularly the differences of complications between needle sizes(22 gauge and 25 gauge), has been done by our department. The following results were observed: 1) The most common sequelae of spinal anesthesia was hypotension(35.6%) and in order frequency, urinay difficulty(23.3%), headache(16.7%), lumbago(15.3%), nauses of and vomiting(12.8%), dyspnes(8.9%), auditory and visual disturbances(0.83%) and minor neurologic sequelse(0.56%). 2) The incidence of headache and lumbago was more frequent in the 22G, group, but there were no statistically significant differences(p>0.05). 3) The incidence of headache was higher in the females than the males and there were statistically significant differences(p<0.01). 4) The incidence of lumbago was higher in the fourth decade (21.7%), and females showed a higher incidence than in males and there were statistically significant differences(p<0.05). 5) The incidence of lumbago and headache and the degree of headache was without correlation to the number of punctures in both groups(22G group and 26G group). 6) The time to postoperative urination had no correlation to the level of anesthesia.

OBJECTIVES: The challenge of an increasing elderly population has coupled with everpresent social concerns in Korea. A major problem in health center for the frail older people is that medical, healthcare, and welfare services are often fragmented in terms of providers and settings without appropriate coordination. The purpose of this study was to investigate the need of health center-based integrated healthcare services and its related factors for the elderly. METHODS: A total of 110 elderly people who had visited at a county Health Center were interviewed using a self-administered questionnaire from November to December, 2005. The questionnaire consists of five domains according to the Program of All-inclusive Care for the Elderly. RESULTS: Respondents had high need (total mean score with the 5-point Likert-type sacle: 3.67) of health center-based integrated healthcare services including home visiting service (mean: 4.08), chronic disease care service (mean: 4.06), and transportation service (mean 4.05). According to the results of hierarchical multiple regression analysis, among three regression models the magnititude of the variance of full model that is explained by the need of welfare-domain service was significantly larger than two reduced model. Income was a significant variable in increasing the need of health care and welfare services. CONCLUSIONS: This study suggests that the health center-based integrated healthcare services for the elderly must be continuously developed and provided for the health promotion and improved the quality of life of the elderly who live in rural area in Korea.

This study was done to report the epidemiologic characteristics of medical retirement from the Republic of Korea (ROK) Army due to visual impairment and to suggest a practical screening system for the draft. The medical records of 423 eyes of 301 patients who retired from the ROK Army due to visual impairment were reviewed retrospectively between January 2010 and December 2014. The patients were grouped by the presence of trauma, and each group was subdivided by military rank. We analyzed demographic and ophthalmic data, including the etiology of ophthalmologic disease. The etiology was classified into 5 anatomical categories (ocular surface, lens, retina, optic nerve and extraocular visual pathway, and extraocular muscle and orbit), which were then subdivided into the type of disease. The mean age was 24.5 years, and non-traumatic mechanisms accounted for 81.1% (343/423 eyes) of medical retirements. Visual acuity was better in patients without trauma. In enlisted soldiers, disease in the optic nerve and extraocular visual pathway was the most common anatomical category (40.5%), and primary open angle glaucoma (30.8%), retinal dystrophy (18.3%), congenital cataract (14.5%), and retinal detachment (9.7%) were the four most common diseases. Most medical retirements due to visual impairment resulted from non-traumatic mechanisms, even though patients were young. The fundus examination and visual field test would be more useful tools than a conventional vision test for large-scale draft screening for the most common two disease types: primary open angle glaucoma and retinal dystrophy.

The toxicity and adrenostatic effect of o,p'-DDD, a derivative of the insecticidal DDT, on the adrenal cortex were well known. It known that the toxicity was based on the blocking of steroid biopsynthesis when cholesterol was converted to pregnenolone. Lysodren(R) was also known to be capable of producing a regression of adrenocortical carcinoma and its metastases, and this drug became one of useful choice for the treatment of unoperable adrenocortical carcinomas. Recently, fine structural effect of o,p'-DDD on the adrenocortical carcinoma show that the mitochondria is the primary target organelle. o,p'-DDD was dissolved in corn oil and it was orally administered for 28 days to investigate the ultrastructural effects of zona fasciculata of rat adrenal cortex. The results obtained were as follow: 1) The body weight was decreased after feeding o,p'-DDD. 2) Light microscopic examination showed no remarkable change except increased fine lipid droplets of zona fasciculata in group I (o,p'-DDD 75 mg/kg feeding). Moderately increased intracytoplasmic lipid droplets and pyknotic nuclei bearing membrane indentations were seen in group II (o,p'-DDD 150 mg/kg feeding). Large sized lipid droplet aggregates, pyknotic nuclei with severe nuclear membrane indentations and karyorrhexis in focal area were evident in group III. 3) Immunohistochemical staining for ACTH in pituitary gland showed increasing number of ACTH secretory cell and increasing intensity of staining property according to the dosage of o,p'-DDD. 4) Ultrastructural examination showed increased intracytoplasmic lipid droplets and mild increased peroxisome. There was no remarkable ultrastructural changes in mitochondria in group I. Moderately increased lipid droplets and clusters formation, compressed mitochondria, partial disappearance of mitochondrial cristae, increased peroxisome and nuclear membrane indentations were seen in group II. In group III, nuclear membrane showed prominent indentation. Numberous cytoplasmic vacuolation, double membrane ring in mitochondria, disappearance of mitochondrial cristae, myelin figure formation in mitochondrial matrix, and fatty changes in mitochondrial matrix were seen. These findings showed that the primary target organelle of attack by o,p'-DDD on zona fasciculata of adrenal gland in rat is mitochondria and it was developed from double ring formation in mitochondrial matrix.

We have used BALB/c mice as an animal model for the study of anaphylactic hypersensitivity to the house dust mite. For the sensitization, BALB/c mice were injected with a single dose of extracts of Oermatophagoides farinae (D. pa) or Dermatophagoides pteronyssinus (D. pt) mixed with adjuvants (aluminum hydroxide and Bordetella pertussis) intraperitonealy. On days of 15, 30, and 60 after the sensitization, the mice received a challenge dose of the same allergen intravenously to induce anaphylactic shock. The hypersensitivity reactions were scored by anaphylactic shock. And various immunological parameters, including cytokines and immunoglobulin isotypes, were studied in relation with the shock. A high level of anaphylactic shock was produced in the mice by both of the allergens, D, fa and D, pt, at 15 and 30 days after sensitization. In vitro Ag specific proliferative reponses of spleen cells from D. pt treated mice (D. pt mice) was six times higher than those from O. fa treated mice (O. fa mice). Regardless the differences in antigens, the production of IFN-r by spleen cells from D. pt mice or O. fa mice was equally high at 15 days after sensitization. However, the ability to produce IFN-r by the spleen cells from D, pt mice was three times higher compared to that from D. fa mice. The production of IL-4 by the spleen cells was enhanced slightly but not significant in both groups. In studies of the allergen-specific immunoglobulin isotypes in the sera of the mice, the level of IgE in both groups was enhanced slightly but not significant. In contrast, the level of IgG subtypes were increased in both groups. When the levels of IgG were compared by subtypes, the level of IgG1 increased significantly on day 15 when the anaphylactic shock score was maximized in both groups. Increase in IgG2a level at the day was not significant, instead, asignificant increase in IgG2 levels was observed on day 60 after sensitization when the anaphylaxis was almost discontinued. Although a higher level of IgG3 was examined on day 15 and 30 in D. pt mice and on day 60 in D, fa mice, anaphylaxis was not appeared to be associated with the levels of IgG3 in this study. The IgG1, rather than IgE, was assumed to the major factor involved in the anaphylactic response observed in this experiment. In conclusion, BALB/c mice would be an animal model for the study of anaphylactic hypersensitivity to D. fa or D, pt., which might be an essential tool for the future development of immuno-therapeutic agents.
