Twenty five cases of fractures of the femur & tibia on the same leg (floating knee) in 24 patients were treated in St. Mary's Hospital, Catholic Medical College and Center during the period 1977-1985. We studied all of these patients, divided by four groups according to the methods of treatment, retrospectively with analysis of treatment and end result. Our policy of treatment for these multiple fractures in single extremity was directed toward early weight bearing, active and passive knee exercise by early open reduction and rigid internal fixation for both fractures. The results obtained were as follows: l. Of 25 cases, 20 patients were male and 5 were female. 2. The right lower extremity has constituted 56% of the cases. 3. Average age of patients were 37 years. 4. Most common level of fractures was on middle one third of femur (71.4% ) and proximal one third of tibia (46.2%). Of these 25 cases, three cases of femur and one case of tibia were segmental fractures, and one case of femur and five cases of tibia were open fractures initially. 5. Of 28 cases of femur fracture, 23 were given operative treatment and five conservative method. But out of 26 cases of tibia fracture, each half cases of fracture were treated operatively and conservatively. 6. We analysed the final results of treatment by the time of fracture union roentgenologically and five lower limb functions clinically at the termination of treatment. The average time for fracture union was 20.5 weeks for femur and 21.9 weeks for tibia roentgenologically. The acceptable clinical results could be achieved in 18 cases (72%) of early open reduction and rigid internal fixation for both tibia and femur as early as possible after accident for early knee exercises. 7. The status of fractured tibia was the most important factor to treat these multiple fractures in single extremity because of troublesome to start knee exercise and weight bearing.

OBJECTIVE: Lectins are cell-agglutinating and sugar specific proteins or glycoproteins of non-immune origin that precipitate glycoconjugates having saccharides of appropriate complementarity. Because of these properties, plant lectins have been used to help characterize the carbohydrate moieties of glycoproteins in the zona pellucida (ZP) of several mammalian species including pigs. Treatment of oocytes with various lectins blocks sperm binding to the ZP in various mammalian species. This study was undertaken to examine the distribution of sugar residues in the ZP of pig oocytes matured in vitro and the ability of spermatozoa to bind to ZP and in vitro penetration in oocytes treated with fluorescein isothiocyanate (FITC)-labelled lectins. MATERIALS AND METHODS: The lectins of Banderiaea simplicifolia (BS-II, bind to beta-D-Nacetylglucosamine), Canavalin ensiformis (Con A, bind to alpha-D-Mannose), Lens culinaris (LCA, bind to alpha-D-Mannose), Ricinus communis (RCA-I, bind to beta-D-Galactose) and Ulex europaeus (UEA-I, bind to alpha-L-Fucose) were examined for spermatozoa penetration, binding capacity to ZP and distribution of lectins. RESULTS: The penetration rates were significantry (p<0.05) higher in control oocytes (63%) than those treated with all lectins, but penetration rates (40~49%) were simililar in group treated with lectins. The incidence of monospermy was similar in oocytes untreated and UEA-I, but it was higher in oocytes treated with BS-II, Con A, RCA-I and LCA. The porcine oocytes cultured for 48 h in TC-199 medium were freed from cumulus cells and treated for 30 min with fluorescein isothiocyanate-labelled lectins. When examined under fluorescein illumination, higher (p<0.001) proportions of oocytes showed fluorescein of zona pellucida after treatment with Con A (93%), LCA (93%) and RCA-I (100%) than BS-II (37%) and UEA-I (50%). All of the oocytes treated with RCA-I exhibited strong fluorescein in the outer region of the zona pellucida while those treated with LCA exhibited strong fluorescein throughout the zona pellucida. BS-II bounded mainly to the outer region and UEA-I bounded mainly to the inner region of the zona pellucida, with either strong or weak fluorescein. At 120 min after insemination in vitro, fewer spermatozoa were bound to the zona pellucida of the oocytes treated with BS-II, Con-A and RCA-I. Of the lectins, Con A most inhibited sperm binding. CONCLUSIONS: These results suggest that beta-D-Galactose residues in the porcine zona pellucida may act as primary sperm receptors and inducers of the sperm acrosome reaction and these sugar residues may be involved in the block to polyspermy.

Dermatomyositis is a disease of unknown etiology characterized by inflammation and degeneration of skeletal muscles and cutaneous abnormalities. Cardiac involvement in dermatomyositis-polymyositis is thought to be rare. In recent year, however, there has been an increasing number of reports on cardiac abnormalities in adult dermatomyositis and polymyositis due to development of noninvasive diagnostic techniques. Categorically, these abnormalities have included electrocardiographic changes, cardiac arrhythmias, congestive heart failure, coronary artery disease, and pericarditis. A 56-year-old woman was admittied to the Ewha womans University Hospital with dyspnea and palpitation. She was diagnosed as having dermatomyositis and followed up our department of Dermatology. Electrocardiogram showed a paroxysmal supraventricular tachycardia at as rate of 195/min. The patient was treated with 240mg/day verapamil p.o, 60mg/day prednisone p.o, there was marked improvement of symptoms. Systematic study of cardiac function utilizing echocardiography, Holter monitoring, thallium-201-scan, and gated blood pool studies were conducted in five newly diagnosed patients with dematomyositis-polymyositis. A significant elevation of serum CPK-MB is indicative of cardiac involvement. Cardiac involvement is a serious prognostic sign. We report a case with the review of the literature.

BACKGROUND: The appearance of multiple-drug-resistant Mycobacterium tuberculosis strains has been seriously compromising successful control of tuberculosis. Rifampin-resistance, caused by mutations in the rpoB gene, can be indicative of multiple-drug-resistance, and its detection is of great importance. The present study aimed to develop an oligonucleotide chip for accurate and convenient screening of drug-resistance. METHODS: In order to detect point mutations in the rpoB gene, an oligonucleotide chip was prepared by immobilizing specific probe DNA to a microscopic slide glass by a chemical reaction. The probe DNA that was selected from the 81 bp core region of the rpoB gene was designed to have mutation sites at the center. A total of 17 mutant probes related to rifampin-resistance including 8 rifabutin-sensitive mutant probes were used in this study. For accurate determination, wild type probes were prepared for each mutation position with an equal length, which enabled a direct comparison of the hybridization intensities between the mutant and wild type. RESULTS: Mycobacterial genomic DNA from clinical samples was tested with the oligonucleotide chip and the results were compared with those of the drug-susceptibility test in addition to sequencing and INNO-LiPA Rif. TB kit test in some cases. Out of 15 samples, the oligonucleotide chip results of 13 samples showed good agreement with the rifabutin-sensitivity results. The two samples with conflicting result also showed a discrepancy between the other tests, suggesting such possibilities as existence of mixed strains and difference in drug-sensitivity. Further verification of these samples in addition to more case studies are required before the final evaluation of the oligonucleotide chip can be made. CONCLUSION: An oligonucleotide chip was developed for the detection of rpoB gene mutations related to drug-susceptibility. The results to date show the potential for using the oligonucleotide chip for accurate and convenient screening of drug-resistance to provide useful information in antituberculosis drug therapy.
