A case of toxic epidermal necrolysis (TEN) was presented in 46 year-old male patient. The characteristic skin lesions of TEN were developed after some medictions and tetanus anti-toxin (TAT) injection due to trauma. Probably, the cause of the disease was drugs, TAT injection or trauma inself. On the pathologic findings, lower epidermis and dermo-epidermal cleavage were noticed. He was treated with massive antibiotics and steroid. About 7 days after therapy, much improvement achived. However foul odorous yellowish discharge was noticed since 20 days of hospitalization. Wide debridement of necrotic tissue was carried without improvement. Patient expired on 48th hospital day due to sepsis and impending hepatic coma.

Serum zinc is an essential element in men and animals. Recently on the dermatologic fields, the serum and the skin levels and the roles of zinc have been studied especially in acne vulgaris, but the results were controversial. So to confirm the previous reports and for evaluation of the relationship between the various aspects of acne vulgaris and the serum levels of zinc, the serum levels of zinc were measured by atomic absorption spectrophotometer in 13 healthy controls and 46 patients with acne vulgaris. In the healthy controls, their mean values of zinc were 0.843+0.251 ppm in total, 0.920+0.219 ppm, in females and 0.777+0.260 ppm in males. There was no statistical difference attributable to sex. In the 46 patients with acne vulgaris, their mean value of zinc was 0.741+0.195 ppm. There was no significant difference in the mean serum zinc level compared with the controls. In the males with acne, the mean va1ue of zinc was 0.727+0.166 ppm, and 0.748+0.208 ppm in females with acne. There was no significant statistical difference between males and females with acne. And females, but not males, with acne had significantly lower serum zinc levelss than controls of the corresponding sex. (p<0.1) By clinical severity, classifying the 46 patients with acne vulgaris into three groups: mild type (only comedones), moderate type (comedones with pa.pules) and severe type (includes pustules, comedones, and papules, etc.), the serum zinc levels of each group were 0.774+0.185 ppm, 0.7880. 200 ppm and 0.666+0.176 ppm. The significant statistical difference was found only in the severe type of acne compared with the healthy controls (p<0.05). Also classifying the patients into three groups (acute, moderate and chronic types of acne) by duration of acne, the serum values of zinc were 0.738+0.158 ppm, 0.692+0.283 ppm and 0.769+0.241 ppm, respectively. Only in the moderate type of acne, the mean serum level of zinc was significantly reduced compared with the control group (p<0.1)

This study was designed to investigate the effect of GABA and related substances on the spontaneous contraction of rat small intestine. The rats (Sprague-Dawley), weighing 200-250g, were sacrificed by cervical dislocation, and the small intestine was isolated. Longitudinal muscle strips from duodenum, jejunum and ileum were suspended in Biancani's isolated muscle chambers and myographied isometrically. GABA and muscimol, a GABA A receptor agonist relaxed the duodenum and jejunum significantly, but baclofen-induced relaxation in those muscle strips negligible. The effectiveness of GABA and muscimol in various regions were the greatest on duodenum, and greater on jejunum than on ileum The effect of GABA and muscimol was antagonized by bicuculline, a competitive GABA A receptor antagonist and picrotoxin, a noncompetitive GABA A receptor antagonist. Duodenal relaxation induced by GABA and muscimol was unaffected by hexamethonium, but was prevented by tetrodotoxin. These results suggest that GABA inhibit the contractility of smooth muscle with distinct regional difference of efficacy, and the site of inhibitory action is the GABA A receptor existing at the presynaptic membrane of postganglionic excitatory nerves.

STATEMENT OF PROBLEM: Proper proximal contact is important for maintaining and stabilizing the dental arch. However, the proximal contact strength (PCS) is not a constant value and can be affected by a variety of factors. PURPOSE: This study examined the influences of postural changes on the posterior PCS. MATERIAL AND METHODS: Twelve adults with a normal occlusion and had not undergone prosthetic treatment or proximal restoration were participated in this study. A metal strip was inserted into the proximal surface and removed at a constant velocity. The contact strength was measured in every contact point between canine to second molar in both arches. The PCSs were obtained initially in the upright position, secondly in the supine position and finally in the upright position again. All measurements were repeated after a 2 hour period. Statistical analysis was carried out using the Friedman test (P < .05). RESULTS: Generally, a decrease in PCS occurred when the posture was changed from the initial upright to supine position, while it increased when the posture was changed from the supine to upright position. A significant change was observed in all areas except for between the canine-first premolar in the maxilla and between the first molarsecond molar in the mandible areas. CONCLUSION: The posterior PCS, which dentists generally believe to be a static feature of occlusion, is affected significantly by posture.

In the developed countries in Europe and the United States, The spinal tuberculosis is of no serious problem due to the developed anti-tuberculotic agents and the advanced operative techniques. However, in Korea poor economic and other conditions prevent many patienta from getting proper treatments for spinal tuberculosis. We analysed 45 cases of spinal tuberculosis who were treated at our department during three years from June, 1972 to June, 1975 by operative treatment and being compared with these results that obtained conservative treatment. The results were obtained as follows; 1. There was most common in below 9 years old (28.9%) and common age incidence was below 35 years old (68.8), The sexual incidence was 22 in male and 23 in female. 2. Lower thoracic and upper lumbar were mostly involved, i.e thoracic (52.2%), lumbar (32.7%), thoraco-lumbar in orders. 3. Two affected vertebra was most common in 33 cases, number of affected vertebra averaged 2.5. 4. In laboratory finding, E.S.R. that was 50–60 mm/hr. in average of then admission wss shifted as normal range of 10–20 mm/hr. after cure of 5–6 months. 5. In 28 cases of operative treatment, anterior spinal fusion was done in 19 cases (67.9%), posterior spinal fusion in 8 cases(28.6%), one case(3.5%) was treated by thoracotransversectomy. 6. In consequence of pathologic exaraination and A.F.B. stain, the case of tuberculotic constitution was 18 in tissue pathology, and that of positive reaetion was 9 in direct smear for A.F.B. 7. The case that tuberculosis was limited at spine and was not found in other organs was 27, it got from 60% of the whole. 8. Average kyphotic angle of the thoracic region after operation was 4.3°, in 6 months was reduction of 1.8°, that of lumbar region after operation was 1.2°, in 6 months was reduction after operation was reduction of 0.7°, as change of radiologic kyphosis. 9. As a result of being cured during 18 months by operative or conservative methods, not a case is found in activity.

This study was aimed at investigation of the stimulatory innervations on the rat urinary bladder. Detrusor muscle strips of 15 mm long were suspended in isolated muscle chambers containing 1 ml of PSS maintained at 37℃ and aerated with 95% O²/5% Co². Isometric myography was performed, and the results were as followings: Muscle strips showed “on-contraction” by electric field stimulation (EFS) frequency-dependently. The EFS-induced contraction was not affected by hexamethonium, a ganglion blocker, but abolished by tetrodotoxin, a nerve conduction blocker. Physostigmine, a cholinesterase inhibitor enhanced the EFS-induced contraction which was inhibited by hemicholinium, an inhibitor of choline uptake at the cholinergic nerve ending. Such an EFS-induced contraction was antagonized by atropine only partially, and the atropine-resistant portion was completely abolished by the desensitization of purinergic receptors by prolonged incubating of the strips in the presence of high concentration of ATP. Bethanechol, a cholinergic agonist, elicited concentration-dependent contraction. Adenosine triphosphate (ATP), a purinergic agonist, induced a weak but concentration-dependent contraction of short duration. Bethanechol-induced contraction was not affected by ATP-desensitization, and ATP-induced contraction was not affected by tetrodotoxin. These results suggest that there are at least two main stimulatory components of innervations in the detrusor muscle, cholinergic muscarinic and purinergic; and those receptors are independent each other.

STUDY DESIGN: The same contents of questionnaire about the low back pain(LBP) were conducted among the Korean and the Japanese hospital workers. OBJECTIVES: To compare the prevalence of LBP and the correlates of occupation and care-seeking. SUMMARY OF LITERATUR REVIEW: Previous epidemiological researches about LBP were usually performed within a country, Korean researches were for the Korean population and Japanese for the Japanese. MATERIAL & METHODS: The history, the cause, the frequency, the severity, and the method of treatment of LBP were compared between the Korean (N=336) and the Japanese (N=428) hospital workers RESULTS: The prevalence of past LBP history were higher in Korean (80%) than in Japanese case(68%), but the percentage of care-seeking (Japan: 64% & Korea: 49%) and lost workdays (9% & 7%) were inverted. The prevalence was the highest in nurse occupation (73% & 89%), and most of these cases reported the cause of LBP as work-related (72% & 71%), which was much higher than the other occupations (34% & 39%). Among the care-seeking (Japan: N=186, Korea: N=131), the percentage of hospital visit was higher in Japanese (43%) than in Korean case (24%). The other methods of care included pharmacy, massage, finger-pressure therapy, acupuncture and moxa, and these were similarly prefered by two countries. CONCLUSION: Epidemiology of LBP was compared between Japanese and Korean hospital worktors. Further study will be needed to compare the actual epidemiology of an LBP.(232 words)

Most authorities including WHO recommended immununizing infants with BCG as early as possible in areas prevalent with tuberculosis, however the optimal time for immunization has not well been characterized. Therefore the investigation was undertaken by vaccinating various infant groups of different ages with BCG and subsequently evaluating for adverse effects and tuberculin reactions, in order to contribute to undestanding the optimal time for immunization. Four hundred eighty three infants from the newborn nursery and the well baby clinic of Hanyang University Hospital who had no family history of tuberculosis were divided into three groups; group I of infants immunized within 7 days after birth, group II of infants immunized at about 1 month of age and group III of infants immunized at about 3 months of age. To each infant 0.1 ml of BCG(Institute Merieux, France) was administered intradermaly and approximately 3 months later tuberculin skin test using 5 TU PPD (NIH, Korea) was performed. Adverse reactions following BCG vaccination such as temperature elevation, induration alone or with suppuration at or near the injection site, and lymph node enlargement were also analyzed. The summary of the results is as follows. 1) Distribution of diameters of induration on tuberculin skin test illustrated incomplete bimodal configuration in all three different age groups. The means 2 standard deviations of diameters of indurations distributed on the main bells were 10.07 4.52 mm in group I, 10.65 3.82 mm in group II, and 10.83 5.08 mm in group III, and were not significantly different. 2) Criteria for positive tuberculin reaction was diameters of indurations equal to or greater than 6mm, 2 standard deviations below the mean values of diameters of indurations on the main bells. 3) The positive tuberculin reaction rates of 85.8% in group II and 88.6% in group III were significantly greater than 74.1% in group I. 4) Incidence of complications following BCG vaccination including temperature elevation, induration with suppuration, and localized lymphadenopathy was not different among three groups and the serious complications such as temperature elevation and lymphadenopathy were minimal. The data indicate that it is appropriate to immunize infants with BCG at about one month of age and the incidence of complications following BCG vaccination was not different among three infant groups of different ages.
