1.Viral inactivation of disinfectant Tego-51(R).
Korean Journal of Nosocomial Infection Control 1998;3(2):97-100
BACKGROUND: Tego-51(R), one of the amphoteric surfactants, has been considered as an effective disinfectant having both bactericidal and fungicidal effect. The author evaluated inactivation effect of Tego-51(R) on viruses causing disease in humans. METHODS: Influenza virus B, respiratory syncytial virus (RSV), herpes simplex virus 1 (HSV-1), adenovirus and echovirus 30 were exposed to diluted Tego-51(R) solution (1% and 0.1%) for 5, 10 and 30 minutes respectively and were inoculated onto the following cells: Influenza virus B, MDCK; RSV, HEp-2; HSV-1, HEp-2; adenovirus, Vero; and echovirus 30, RD. After incubation for 5 to 6 days, viral infection was identified with indirect immunofluorescent methods. RESULTS: Influenza virus B, RSV and HSV-1 which are enveloped viruses were inactivated after exposure of the viruses to Tego-51(R) for 5 minutes. Non-enveloped adenovirus and echovirus 30 were not inactivated after exposure for 30 minutes. CONCLUSIONS: Tego-51(R) appears to be effective in inactivation of enveloped viruses at concentrations used for disinfection of pathogenic bacteria and fungi.

5.Study on Multistage Maximal Stress Exercise Test.
Korean Circulation Journal 1983;13(1):151-164
The maximal stress exercise test was studied in 49 normal korean and 231 cases of various diseases. Bicycle ergometer was used in 122 cases and treadmill was used in 109 cases by modified Bruce protocol which was designed by author. The maximal heart rate, maximal work capacity, End point of maximal exercise and ST changes especially in coronary artery disease were investigated. Total 231 cases in cluded 8 cases of myocardial infarction, 46 cases of anginal pectoris, 91 cases of atypical anginal pain, 68 cases of hypertension and 18 and of diabetes mellitus. The results are as follows; 1. The maximal heart rate was markedly reduced in myocardial infarction(115/min. comparing 162/min. in normal) and slightly less reduction in angina pectoris. Also mild reductions were observed in atypical anginal pain, hypertension and diabetes mellitus. 2. The maximal work capacity was markedly reduced in myocardial infarction(93 wt comparing 180 wt in normal). It was only slightly reduced in anginal pectoris, atypical anginal pain, hypertension and diabetes mellitus which were not significantly reduced from that of normal, especially in anginal pectoris, the reduction on maximal work capacity was unremarkale comparing that of maximal heart rate. 3. The End point of maximal exercise test were exhaution in 34%, leg pain in 30%, maximal heart rate in 22%, ST depression more than 1 mm in 21%, dyspnea in 19%, anginal pain in 15% by bicycle ergometer, while by treadmill test, the End point were exhaution in 47%, dyspnea in 35%, Maximal heart rate in 22%, ST depression more than 1 mm in 19%, leg pain in 15% and anginal pain in 10%. 4. In coronary artery disease, the positive maximal exercise test(sensitivity) was 76% in treadmill test and 68% in bicycle ergometer test. 5. The ST changes among 231 patients druing the maximal exercise test occured in 47 cases(20%). In 43 cases the ST segment depressed more than 1 mm and the degree of depression ranged 1-3.5mm. The upward sloping type and horizontal depression type were equally common. There were 4 cases(1.7%) of ST elevation during exercise which returned to normal after exercise. There were 3 cases among 54 cases of coronary artery disease(5.5%) and 2 cases among 46 cases of anginal pectoris(4.3%). In one case of anginal pectoris with elevated ST segment, myocardial infarction occured in few days later. Therefore it appears that the variant angina in this study is very few.

Korean Journal of Clinical Pathology 1997;17(4):643-649
BACKGROUND: Identification of specific antinuclear antibodies is useful for the diagnosis, subclassification and determination of prognosis in autoimmune disorders. In many diseases, multiple autoantibodies are detected, and simultaneous detection of multiple autoantibodies has been shown to be useful. Recently, a commercial kit (EL-ANA/6 profiles, TheraTest Laboratories, USA) losing enzyme-linked immunosorbent assay (ELISA) method for detection of six specific autoantibodies is avallable. In this study, we attempted to compare the results of EL-ANA/6 profiles with those of routinely used methods and evaluated usefulness of EL-ANA/6 profiles. METHODS: EL-ANA/6 profiles were performed with 28 sera which were positive for fluorescent antinuclear antibody (FANA) Simultaneously we tested anti-dsDNA antibodies with immnofluorescent (If) method and anti-Sm, anti-RNP, anti-SSA and anti-SSB antibodies with double immunodiffusion (DID). To evaluate specificity, EL- ANA/6 profiles tests were performed on 10 sera from healthy blood donors. RESULTS: Ten sera of healthly blood donors were all negative for EL-ANA/6 pro biles. In the results of EL-ANA/6 profiles on sera positive for FANA, the concordance rate with IF method for the anti-dsDNA antibodies was 89.3% (25/28) and the con- cordance rates with DID for anti-Sm, anti-Sm/RNP, anti-SSA and anti-SSB antibodies were 85.7% (24/28), 82.1% (23/28), 92.9% (26/28) and 82.1% (23/28), respectively. In 16 discordant settings, thirteen (81.3%) were negative on DID and positive on EL-ANA/6 profiles. CONCLUSIONS: The results of the EL-ANA/6 profiles show good concordance rates with If and DID. EL-ANA/6 profiles showing quantitative profiles for multiple autoantibodies is useful for diagnosis and tool)ow-up of autoimmune disorders.

Previously severe multiple injuries associating the segmental fractures of the femurs were reported to be rare, and as a rule were fatal when surgeons did not immediately give or provide excellent care. Recently many patients having those injuries are quite often encountered at the clinic. The reason is high incidence of the mass casualties by road accidents, mine accidents and accidents at the industrial complexes. Also as the other reason, the advanced resuscitative measures which could do many of these patients to survive can be listed. For those severely injured patients associating segmental fracture of the femur, the more positive and efficient diagnostic and therapeutic measures have to be sought. Authors analyzed the 18 cases of segmental fractures of the femurs who were treated at the Orthopedic department of Catholic Medical College & Center from Jan., 1974 to Dec., 1979. The results obtained were as follows: 1. The male patients outnumbered the female in ratio of 13/5, and the most were at their 4th and 5th decade of age. 2. Traffic accident was the main cause of the injury; 13 out of 18 cases. Remaining 5 cases sustained injury by industrial accident. 3. All but one were closed fracture, and segmental shaft fracture was the commonest type of them; 10 out of 18 cases. 4. Thirteen patients accompanied significant injuries to other vital organ and/or other musculoskeletal system. 5. In entire cases the average union time in the proximal fracture was 28.9 weeks, and in the distal one 17.5 weeks. 6. Fractures regardless of their group that needed late bone grafting procedure numbered 7; 6 in the proximal shaft fracture and one in the distal fracture. 7. In 10 cases of the segmental shaft fracture (Group III fracture), bony union in the proximal fracture was obtained at 29.6 weeks in average. Proximal fractures in 4 cases in this group needed late bone grafting. Through these results it is suggested that in the treatment of segmental fracture of the femur, primary bone grafting at the proximal fracture site is beneficial to promote fracture healing or to prevent delayed union or nonunion especially when the proximal fracture is located across mainly the cortical part of the bone. Methods of treatment necessarily have to be selected according to the site and shape of the fracture, and in cases of segmental shaft fracture Kuntscher nailing is preferably recommended although the distal fracture site is not ideal one for the Kiintscher nail fixation.

CT findings of 19 kidneys in 12 patients with renal and perirenal non-Hodgkin's lymphoma were retrospectively reviewed to determine distinguishing characteristic and specific findings. CT manifestation of the renal and perirenal lymphoma included multiple nodules in five kidneys(26.3%), trans-capsular infiltration in three kidneys(15.8%). trans-sinus infiltration in nine kidneys(47.4%) and diffuse infiltration in two kidneys(10.5%0. Perirenal changes were thickening of the renal fascia in ten kidneys(52.6%) and crescentic lesion of low attenuation in the subcapsular area in five kidney(26.3%). Retroperitoneal lymphadenopathy was evident in eleven patient(57.9%). Renal calyceal dilatation without renal pelvic dilatation(selective calcelal dilatation) was noted in three kidneys. Familiarity with these CT findings of renal and perirenal lymphoma may be helpful in the diagnosis and management of patient with non-Hodgkin's lymphoma.
