The anterior discectomy is widely accepted method for removal of the herniated disc material of cervical spine due to direct visualization of the lesion site. In addition, it is believed to prevent recurrence of herniation, progression of degenerative change, and to preserve normal cervical lordosis after the fusion. For more effective anterior fusion and early postoperative ambulation without prolonged external support, internal fixation technique was introducsuspected to influence the result of operation, the type of bone graft and age of the patient may be the effective factors to the late result. ed. Authors reviewed 36 patients with cervical disc herniation and evaluated the result of anteior discectomy and fusion with plate fixation. With a mean follow up of 34 months, there were remarkable symptomatic improvement at most instances and bony union in situ within 3 months in all cases after the operation. Disclosed complications were 2 cases of hoarseness which was improved spontaneously, and 1 case of dysphagia. At the comparison of the effect of the factors which were suspected to influence the result of operation , the type of bone graft and age of the patient may be the effective factors to the late result.

Responses of mouse lymphocytes to the soybean paste fermented by Korean traditional fashion was examined to clarify its effects in cytokine production in vitro. A fraction of the soybean paste (KFSP-100) was prepared by precipitation with ammonium sulfate and by filtration through ultrafiltration membrane. KFSP-100 were added into cultures of fresh mouse splenic cells in vitro. KFSP-100 significantly enhanced the amount of IL-6 and TNF-a produced by macrophages and IL-6 and IFN-r produced by lymphocytes. Production of IL-12 by macrophages was not much affected by KFSP-100 treatments. The most noticeable finding was the fact that lymphocytes treated with KFSP-100 proliferated to an exceeding numbers (more than 10 times to the control) in 72 hours. The KFSP-100-induced proliferative response was specific to B cells since almost all of the KFSP-100-induced cells in the cultures of splenic cells were B cells. Furthermore, such a proliferative responses were equally observed only in cultures of purified B cells but not in cultures of T cells. In thermostability test, the biologically active components of the KFSP-100 is assumed to be either linear protein or glycoprotein. KFSP-100 did not induce agglutination of lymphocytes demonstrated by lectins in the same cells. These observations suggest that KFSP-100 may be a novel mitogen for B lymphocytes. The component (s) responsible for the B cell proliferation in KFSP-100 might be a factor gained by natural fermentation. None of the fractions of not fermented soybean paste prepared by the same methods demonstrate the same effect.

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.

Three-types of expandable metallic stents were constructed to evaluate the differences between the stents : one, formed in a cylindrical zigzag pattern with stainless steel wire (Gianturco stent), another, made by coating the Gianturco stent with silicone rubber(Silicone stent), the third, made by coating the Gianturco stent with 24 carat gold(God stent) for tissue acceptance. A total of 69 stents(each 23 stents of Glanturco, Silicone, and Gold stents) of 8-12 mm in diameter and 20 mm long were placed into normal abdominal aorta, inferior vena cava and iliac artery of nine adult dogs for 2 weeks to 11 months. It was more difficult to introcuce Silicone stent into an introducing sheath than Gianturco or Gold stent due to the thickness of silicone rubber, Four Gianturco stents and three Silicone stents showed migration but Gold stent did not. Luminal narrowing or occlusion was noted in 3 Silicone stents, in 2 Gianturco stents, and in 1 Gold stent. Neointimal proliferation over the stent wires was more rapid and even in God stent than Silicone or Gianturco stent. Although further study is needed, Gold stent seems to be better than Gianturco or Silicone stent as an endovascular graft material.

PURPOSE: This study is aimed at obtaining the information on the physical fitness level of female flight attendants at a local airline. METHODS: The subjects are 2,409 female flight attendants who have had medical examination and physical fitness tests at an airline medical center from January 2 to December 30, 2008. The independent variables include socio-demographic & behavioral characteristics, and medical examination results, whereas the dependent variable is their physical strength score representing their fitness level. RESULTS: Factors that affect the fitness strength score are age, flight hours per year, and fasting blood sugar level. It is found that physical fitness level is higher when the subjects are over 35, on board for over 850 hours per year and their fasting blood sugar level is over 100 mg/dL. CONCLUSION: It is concluded that for the improvement of flight attendants' health, more exercise to develop cardio-respiratory endurance and muscular strength is needed, and further study needs to be done to develop fitness enhancement programs considering flight attendants' job characteristics, working years, and flight hours per year, and programs for those returning to their workplace after a long-term leave, and new employees.

We report an extremely rare case in which two tuberculids, papulonecrotic tuberculid and erythema nodosum, occurred together. A 16-year-old girl had two types of clinically distinct lesions; asymptomatic necrotic papules on the upper and lower extremities and painful subcutaneous nodules on the legs. A Mantoux test showed a strong positive reaction. Histopathologic findings of the necrotic papule and subcutaneous nodule were consistent with papulonecrotic tuberculid and erythema nodosum, respectively. There was no extracutaneous focus of tuberculosis. Polymerase chain reaction for tuberculous bacilli in the papulonecrotic tuberculid lesion revealed a negative result. Antituberculous therapy brought a rapid clinical improvement of both lesions.

A 48-year-old woman, who had had tattoo on her eyebrows, was seen with pruitic erythematous indurated plaques on the tattooing sites. The skin react ion was begun to observe about 4 weeks after getting tattoo. Skin biopsy specimens from the indurated lesions showed granulomatous reactions. Intradermal tests by means of multiple pricks and patch test were done on her low back with the same tattoo dye and also 4 others available in Korea. Serial punch biopsy specimens were obtained from the sites of intradermal test at 2nd, 7th, 28th, and 56th day after intradermal test. Granulomatous reactions were found in the spiecimens taken at the 28th and 56th day.

STATEMENT OF PROBLEM: Use of custom tray and tray adhesive is clinically recommended for elastomeric impression material. However there is not clear mention of drying time of tray adhesive in achieving appropriate bonding strength of tray material and impression material. PURPOSE: This study is to investigate an appropriate drying time of tray adhesives by evaluating tensile bonding strength between two types of polyvinylsiloxane impression materials and resin tray, according to various drying time intervals of tray adhesives, and with different manufacturing company combination of impression material and tray adhesive. MATERIAL AND METHODS: Adhesives used in this study were Silfix (Dentsply Caulk, Milford, Del, USA) and VPS Tray Adhesive (3M ESPE, Seefeld, Germany) and impression materials were Aquasil Ultra (monophase regular set, Dentsply Caulk, Milford, Del, USA) and Imprint II Garant (regular body, 3M ESPE, Seefeld, Germany). They were used combinations from the same manufacture and exchanged combinations of the two. The drying time was designed to air dry, 5 minutes, 10 minutes, 15 minutes, 20 minutes, and 25 minutes. Total 240 of test specimens were prepared by auto-polymerizing tray material (Instant Tray Mix, Lang, Wheeling, Il, USA) with 10 specimens in each group. The specimens were placed in the Universal Testing machine (Instron, model 3366, Instron Corp, University avenue, Nowood, MA, USA) to perform the tensile test (cross head speed 5 mm/min). The statistically efficient drying time was evaluated through ANOVA and Scheffe test. All the tests were performed at 95% confidence level. RESULTS: The results revealed that at least 10 minutes is needed for Silfix-Aquasil, and 15 minutes for VPS Tray Adhesive-Imprint II, to attain an appropriate tensile bonding strength. VPS Tray Adhesive-Imprint II had a superior tensile bonding strength when compared to Silfix-Aquasil over 15 minutes. Silfix-Aquasil had a superior bonding strength to VPS Tray Adhesive-Aquasil, and VPS Tray Adhesive-Imprint II had a superior tensile bonding strength to Silfix-Imprint II at all drying periods. CONCLUSION: Significant increase in tensile bonding strength with Silfix-Aquasil and VPS Tray adhesive-Imprint II combination until 10 and 15 minutes respectively. Tray adhesive-impression material combination from the same company presented higher tensile bonding strength at all drying time intervals than when using tray adhesive-impression material of different manufactures.
