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.

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.

During general anesthesia, removal of exhaled carbon dioxide by rebreathing appliances is provided by chemical absorption and this carbon dioxide absorption during anesthesia would at first glance seem to be a simple problem. The problem, however, is far more complicated and much attention must be given to details of rebreathing appliances. Incomplete removal of carbon dioxide in circle absorber systems, which are commonly used today must be carefully monitored to prevent hypercapnea caused by accumulation of carbon dioxide in the breathing circuits. Although circle absorbers have been developed through clinical trials anesthesiologists have no reliable indication of the end point of useful life of the absorbent. This study was undertaken to investigate the useful life of the soda lime used in two type of canisters (type A: canister of anesthesia machine. Quantiflex, USA. 12.9cmX16.6cm, tbye B: canister of anesthesia machine, International 2. U.K., 13.1cmX16.9cm). the effect of flow rate on this useful life and the relations between indicator change and the endpoint of useful life of the soda lime. The control group used a as total flow rate of fresh gases at 2.0 liters per minute and the experimental group used a total flow rate of 4.0 liters per minute. The carbon dioxide concentration of 0.1% at the canister exit was employed as the end point of useful life of the absorbent and the exit carbon dioxide concentration were monitored continuously by intra-red carbon dioxide monitor apparatus(Datex Normocap CD-102, Pinland). Also the carbon dioxide concentration in the respiratory circuit of exhaling side was examined. The results were as follows: 1) In type A, the average useful life of soda lime was 1,885 minutes in the control group and 2,514 minutes in the experimental group. In type B, the average useful life of soda lime was 1,587 minutes in the control group and 1,980 minutes in the experimental group. 2) At the end point of useful life of the absorbent the level of the color change of the indicator of the absorbent in all types was above the three-fourth height of two chambered canister. 3) At the end point, end tidal CO2 concentration was 3.5 vol% in the control group 2.88 vol% in the experimental group. The data obtained from this observation indicated that the increase of total flow rate of gas and the type A canister prolonged the useful life of soda lime and that the double chambered canister could be used safely until the color change of the indicator reached the level of three fourth the height of the canister.

In 1943, Alberto Inclan reported tumoral calcinosis in 3 cases at major joints. This condition usually showed large, painless calcified mass in major juxtaarticular sites, and evidence of familial or racial predisposition in blacks but abnormal values of serum calcium and phosphorus, association with renal disease, metabolic disorder and collagen disease are seldom seen. Tumoral calcinosis in large joints such as hip, knee, elbow and shoulder was reported several cases. Tumoral calcinosis in hand and foot is very rare and not reported yet in this country. Recently, authors experienced a case of tumoral calcinosis in both hands and right foot and cured without recurrence in 1 year follow up.

BACKGROUND: In spite of the successful reperfusion therapy, coronary blood flow in infarcted myocardium was known to decrease for a long time. Abciximab is known to inhibit the final pathway of platelet aggregation and maintenance the large vessel patency. But abciximab may have another important effect beyond the these effect. TIMI frame count method is simple, reproducible, objective and quantitative index of coronary flow. We tried to define the effect of abciximab that used with primary angioplasty on the coronary blood flow using TIMI frame count methods. METHODS: We consecutively studied 30 patients who admitted for acute myocardial infarction without cardiogenic shock from September 1997 to August 1999. We analyzed the changes of corrected TIMI frame count(CTFC) between the baseline(immediate after the angioplasty) and follow-up(post-op 7th day) coronary angiogram and compared the results between the group of primary angioplasty with abciximab(abciximab group, n=1) and the group of primary angioplasty without abciximab(non-abciximab group, n=9). RESULTS: There were no differences between abciximab group and non-abciximab group in baseline characteristics, treatment modalities and angiographic results. According to the results of the comparison of deltaCTFC, changing rate of CTFC, deltavelocity and changing rate of velocity, there were significant improvement of the coronary blood flow in infarct related artery in the abciximab group than non-abciximab group. But there were no differences in the changes of coronary blood flow in non-infarct related artery between two groups. The frequency of major adverse coronary events during follow up periods(mean 6 months) were similar(9.1% and 5.2% each other, p>0.05). CONCLUSIONS: Abciximab used with primary angioplasty in acute myocardial infarction improved the coronary blood flow significantly in infarcted myocardium. This finding may be related that abciximab enhance the perfusion and function of microvasculature in infarcted myocardium.

OBJECTIVES: This study was aimed to examine whether participants of a Korean candlelight rally had correct medical information about human mad cow disease and rational attitudes about imported U.S. beef in relation to human mad cow disease. METHODS: A total of 393 face-to-face interviews were conducted, and subjects completed questions about prevalence of senile dementia and human mad cow disease in U.S. and whether they will eat U.S. beef even if no cases of human mad cow disease occurred in the U.S. or if the chance of being affected with human mad cow disease was lower than dying in a plane crash. RESULTS: Correct answer rates to the questions about prevalence of senile dementia and human mad cow disease were 28.2% and 36.1%, respectively. A majority of respondents answered that they would not eat U.S. beef even if there were no reported cases of human mad cow disease in the U.S. or if their chance of being affected with human mad cow disease was lower than dying in a plane crash (75.6% and 86.0%, respectively). CONCLUSION: At least 64.4% of participants had incorrect medical information about human mad cow disease, and their attitudes about imported U.S. beef may be rooted in emotion rather than fact.

Patients with hypertrophic cardiography often complain of chest pain and have electrocardioagrams suggesting myocardial damage or ischemia. Some of three patients have associated coronary arterial atherosclerosis. Transmural myocardial infarction may occur in patients with hypertrophic cardiomyopathy in the absence of significant atherosclerosis of the extramural coronary arteries, about which several pathophysiologic exlpanations were discussed. Presented here, a case of 49-year-old man with hypertrophic cardiomyopathy accompanied with myocardial infarction and angiographically normal coronary arteries is reported. Asymmetric septal hypertrophy, characteristic morphologic abnormality of hypertrophic cardiomyopathy, was progressed to dilated cardiomyopathy after the occurrence myocardial infarction.
