Background: Insulin is known to act as second effector that provides potassium transfer from extracellular fluid to intracellular fluid, thus causing hypokalemia and arrythmia. We evaluated the effect of magnesium sulfate treatment on hemodynamics and serum potassium concentration, induced by continuous infusion of regular insulin solution in rabbits. Method: Twenty-four rabbits were divided into four groups for the experiment. Group I was given intravenouse injection of 5 ml of normal saline and continuous dripping of 7.5 U of RI. Group II was pretreated with 30 mg/kg of magnesium sulfate, followed by continuous dripping of 7.5 U of RI. Group III was given 5 ml of normal saline and 15 U of RI. And Group IV was administered 15 U of RI after 30 mg/kg of magnesium sulfate pretreatment. Venouse blood sampling was done before pretreatment, and after 5, 30, 60 and 120 minutes respectively. Heart rate and arterial blood pressure were taken at the same intervals. Result: 1) There was no significant change in serum potassium concentration in groups injected with 7.5 units of RI respectively (groups I and II), regardless of magnesium pretreatment. But in groups injected with 15 units of RI, the group that was not pretreated with magnesium (Groups III) showed a decrease in serum potassium concentration from 3.39+/-0.57 Eq/L to 2.29+/-0.71 mEq/L, while the concentration in the pretreated group (Group IV) decreased more significantly from 3.35+/-0.50 mEq/L to 1.81+/-0.41 mEq/L. 2) Pulse rate did not change significantly in groups that received continuous infusion of 7.5 units of RI (groups I and II) regardless of magnesium pretreatment, but increased significantly in groups injected with 15 units of RI (groups III and IV), pretreated or not. The pretreated group (group IV) had a more significant rise in pulse rate compared with the group that was not pretreated (group III). 3) In all of the groups, those pretreated with magnesium (groups II and IV) and those not pretreated (groups I and III), there was no significant change in systolic and diastolic blood pressures. Nor was arrhythmia detected. Conclusion: The above results indicate that while magnesium sulfate pretreatment at 30 mg/kg with insulin infusion affects serum potassium concentration, has an antiarrhythmic effect, and may induce tachycardia, it does not have any significant effect on blood pressure.

Articular cartilage can be damaged by trauma or by progressive degradation caused by disease. Unfortunately, it has a extremely limited capacity for repair and regeneration. The use of joint prosthesis has revolutionized but remains limited in its use. To know the possibility of clinical application of clinical application of autogenous bone-articular graft in open complicated intraarticular fractures we studied the change of bone-articular cartilage defect in medial femoral condyle of rabbits and viability of autogenous bone-articular graft stored within abdominal wall of rabbits. The results were obtained as follows: 1. There was over 90% viability of subchondral bone after 10 days storage in the adbominal wall but the articular cartilage showed degenerative change about 40% after 5 days passed. 2. The bone-articular defect was replaced by undifferentiated mesenchymal tissue and fibrous tissue, postoperative 6 weeks later. 3. In implanted bone-articular cartilage graft at 3 days, the chondrocyte of basal cell layer in articular cartilage was relatively well preserved but in 7 days, transplanted articular cartilage graft showed almost necrotic chage. Most of subchondral bones were well healed with host bone without regard to duration of implantation.

The immunoreactivities of surgically removed 16 cardiac myxomas were studies for factor VIII-related Ag (F VIII-RA), Ulex europaeus agglutinin I (UEA-I) and desmin alpha1-antichymotrypsin, and this study was accompained by a clinicopathologic review. More than 50% of the patients with cardiac myxomas were in their fourth and fifth decades, and cardiac myxomas were much more common in women than in men. All but on occurred in the left atrium, and the majority were attached to the atrial septum, usually in the region corresponding to the fossa ovalis. In one case, an atrial myxoma recurred 37 months after the initial excision. Microscopically, the myxomas contained a myxoid matrix composed of acid mucopolysaccharides within which were embedded polygonal cells. The cells forming both the surface and complicated vascular like channels throuhout the myxoid stroma tested positive for F VIII-RA and UEA-I. The outer cell layers of the complex vascular structures demonstrated variable staining for F VIII-RA, while isolated bundles of smooth muscle cells were present and stained for desmin. A small number of the so-called myxoma cells, immunoreactive for alpha1-antichymotrypsin which were not laden with hemosiderin pigment but were similar to histiocytes, were present particularly around the areas of hemorrhage. These findings support the current view that cellular and histologic heterogeneity arose from the divergent differentiation of multipotential mesenchymal cells. In particular, it remains to be confirmed by further study whether or not true histiocytic differentiation occurs.

BACKGROUND: Epidural morphine has been commonly used to provide postoperative pain relief, but it has many side effects such as nausea, vomiting, respiratory depression, and pruritus. The purpose of this study was to evaluate the analgesic efficacy and side effects by combination use of epidural morphine and butorphanol. METHODS: Forty five patients were randomly divided into 3 groups. For group I, a bolus of 4.7 ml of saline and 3 mg of morphine were administered. For group II, a bolus of 4.2 ml of saline and 3 mg of morphine and 1 mg of butorphanol were administered. For group III, a bolus of 3.2 ml of saline and 3 mg of morphine and 3 mg of butorphanol were administered. Continuous epidural analgesia were administered for all groups; group I (saline 99.4 ml and morphine 6 mg), group II (saline 98.4 ml, morphine 6 mg, and butorphanol 2 mg), group III (saline 96.4 ml, morphine 6 mg, and butorphanol 6 mg) by two day infuser, 2 ml/hr. We compared the side effects and analgesic effect of the three groups for 2 days. RESULTS: The incidence of pruritus, nausea and vomiting was reduced significantly in the group II and III, but the incidence of somnolence increased in the group III. There were no significant differences in analgesic effect and the other side effects among the three groups. CONCLUSION: Above results suggest that the addition of butorphanol to morphine in epidural infusion reduce the incidence of pruritus, nausea and vomiting, but increase the incidence of somnolence.

We experienced a case of adenocarcinoma arising in sacrococcygeal teratoma. The patient was a 52-year-old woman. She was admitted due to one month of sacral pain. She had a sacral mass since birth. On physical examination, anal fistula was present at the perianal area and pus drainage was noted. MR image showed multiple variable-sized cysts with inhomogeneous density. Resected specimen, mesuring 12.5 7.0 cm in diameter, showed multiple variable-sized cystic lesions admixed with grayish solid portion. The cysts contained mucoid material. The microscopic examination showed mature teratoma composed of cysts lined by pseudostratified ciliated columnar epithelium, intestinal mucosa, mature cartilage, bone, and fat tissue. A moderately differentiated adenocarcinoma developed from the cystic area in the mass.

This study was conducted to identify the major dietary patterns of Korean adult men and to examine the relationship between subjective stress perception and these dietary patterns using data from the 2014∼2016 Korean National Health and Nutrition Examination Survey (KNHANES). Of the 23,080 total subjects, adult men between the ages of 19 and 64 who did not take the questionnaire or answer the questions relating to depression, and cases where the daily energy intake was less than 500 kcal or more than 5,000 kcal in the Food Frequency Questionnaire were excluded. This left a total of 3,464 subjects who were included in the final analysis. We performed a factor analysis based on the yearly mean intake frequency of 41 food groups to identify the major dietary patterns. Three major dietary patterns were identified (factor loading ＞0.3), including the ‘Healthy pattern’, ‘Processed meat pattern’, and the ‘Alcohol pattern’. The ‘Healthy pattern’ was characterized by higher intake of beans, tofu, vegetable, fish, and fruits. The ‘Processed meat pattern’ was characterized by high consumption of processed meats and instant foods. The ‘Alcohol pattern’ was characterized by a higher intake of alcohol. As a response to the subject's subjective perception of stress, the most answered 'a little' according to age, marital status, occupation, income, residential area, smoking status, drinking status, and exercise status. People whose diets followed the ‘Processed meat’ and ‘Alcohol’ patterns had significantly higher scores on subjective stress perception compared to people following the ’Healthy pattern’.To manage subjective stress, it is more effective to maintain health by relieving stress through a healthy method that combines healthy eating and exercise rather than following an unhealthy diet as characterized by the ‘processed meat’ and ‘alcohol’ dietary patterns.
