Human seminal plasrna (HSP) is mixture of secretion derived from various glands associated with male reproductive tract which comprises approximately 80-90% of the volume of normal ejaculate. The present study was undertaken in an effort to explore the effect of HSP pretreatment on the production of IL-1B, TNF-a and IL-12, in mice, and to investigate if HSP may cause to induce active systemic anaphylaxis (ASA) in mice. In addition, effects of HSP pretreatment on contact hypersensitivity to trinitrochlorobenzene (TNCB), antibody response to polyvinylpyrroridone (PVP), a thymus-independent antigen and on ASA induced by egg albumin (OVA) were also studied in this study. For the experiments of contact hypersensitivity, antibody response and cytokine production, mice were pretreated i.p. daily with 0.3ml of HSP or sterile saline alone (control) for 3 consecutive days before antigen sensitization or lipopolysaccharide injection for the cytokine induction. For the experiments of OVA- induced anaphylaxis, mice were pretreated by a single s.c. injection of HSP 0.3ml per mouse before sensitization. For induction of ASA in mice by HSP, a group of mice were sensitized i.p. 2 consecutive days with 0.3ml of HSP and one day with 0.3 ml of HSP plus 2x10(9) B. pertussis and 1.0 mg of alum (schedule A) or another group of mice were sensitized i.p. with a single i.p. injection of 0.3 ml of HSP with 2x10' B. pertussis and 1.0 mg of alum (schedule B). All sensitized and unsensitized control mice were challenged i.v. with 0.2ml of HSP 14 days after HSP sensitization, and mortality were observed. It was found that HSP pretreatment inhibited the production of IL-lB, TNF-a and IL-12, and also inhibited OVA-induced ASA, contact hypersensitivity to TNCB and anti-PVP antibody production. Interestingly, ASA was induced by HSP irrespective of the applied sensitization schedule. Taken together, this study may provide the direct evidences that HSP may inhibit the production of IL-1B, TNF-a and IL-12 and this may be the first to show the induction of ASA by HSP in mice.

A prospective study was carried out to evaluate the validity of TROPT troponin T rapid assay in early diagnosis of acute myocardial infarction(AMI) in patients with ischemic chest pain, in comparison with conventional diagnostic tools such as serum troponin T(c-TnT) level, creatine Kinase(CK), CK-MB level and initial EKG finding. The study was performed at the emergency department(ED) of Yong Dong Severance hospital from March 1st 1996 to February 28th 1997. One hundred eighty one patients visiting ED with chief complaint of atraumatic chest pain within 24 hours of visit were eligible for the study. Those who lacked enough data collection and those who had chest paint of noncardiac origin and EKG of PSVT were excluded from the study. The overall study population was a total of 131 patients. Initial EKG, TROPT rapid assay, CK, CK-MB and c-TnT level were obtained simultaneously. Diagnosis of AMI was made according to the international diagnostic criteria for AMI. Of the 131 patients 61 patients(46.6%) were diagnosed as AMI. Within 4 hours of their symptom onset, initial EKG showed the highest sensitivity(63.2%) whereas the sensitivities of TROPT rapid assay, c-TnT, CK and CK-MB were poor(0-0.7%). From 4-8 hours, the sensitivities of c-TnT, CK and CK-MB were higher than that of TROPT rapid assay(80% vs. 30%). The sensitivites of TROPT rapid assay, c-TnT, CK and CK-MB rose over time and reached 100% after 8 hours symptom onset. The specificities of the TROPT rapid assay, c-TnT, CK & CK-MB and EKG were all 100% within 8 hours after symptom onset. Discrepancy between TROPT rapid assay and c-TnT was noted in nine patients(6.9%). In this study TROPT rapid assay was valuable in the diagnosis of AMI after 8 hours of symptom onset.

Inflammatory myofibroblastic tumor (IMT) is a space occupying lesion which is composed of myofibroblasts, plasma cells, and lymphocytes. IMT of the maxillary sinus is rare and its etiology is unknown. We present a case of inflammatory myofibroblastic tumor occurring in the right maxillary sinus of a 57-year-old woman. Radiologically, this tumor was interpreted as malignant neoplasm. On histologic examination, bundles of spindle cells were admixed with inflammatory cells including mature plasma cells and lymphocytes. On the basis of the immunohistochemical findings and ultrastructural features, we recognized that the intervening spindle cells were myofibroblasts. We discussed etiology and prognostic factors of this tumor.

Pneumomediastinum is a relatively uncommon, infrequently reported entity, In the evaluation of these entity, it is important to exclude pathological causes, including Boerhaave's syndrome which carries a high mortality. Spontaneous pneumomediastinum is related to excessive intraalveolar pressure leading to rupture of perivascular alveoli in the setting of a Valsalva maneuver without communication to gut material. So, it has a benign self-limited course and rarely requires medical intervention. On the contrary, secondary pneumomediastinum caused by instrumental, traumatic, and spontaneous perforation of esophagus. Although the prognosis have been improved since the advent of broad-spectrum antibiotics and nutritional support, pneumomediastinum due to esophageal perforation still has a high morbidity and mortality. The most important prognostic factor is the time interval between perforation and initiation of therapy, and an awareness and a high clinical suspicion is critical in the early diagnosis and treatment. Recently, we have experienced 2 cases of pneumomediastinum, one case was spontaneous pneumomediastinum and the other may be caused by instrumental esophageal perforation. We report the clinical course of the patients with a current literature review.

The purpose of this study was to compare the histomorphological change of curved root canal preparation using GT rotary File, Profile .04 taper and stainless steel K-file. 45 mesial canals(over 20 degree) of extracted human mandibular first molars were mounted in resin using a modified Bramante muffle system and divided into three groups. The roots were cross-sectioned at 2.5mm, 5mm and 8mm levels from apical foramen. Tracings of the canals were made from preinstrumentation pictures of the cross section. The canals were prepared using a step-back technique with stainless steel K file(group 1), Profile .04 taper rotary file(group 2) and GT rotary file(group 3). Tracings of the prepared canals were made from postinstrumentation picture. Canal centring ratio, amount of transportation, area of dentin removed and shape of canal were measured and statistically were evaluated with Student-Newman-Keuls test using Sigma Stat(Jandel Scientific Software, USA). The results were as followings: 1. Amount of transportation of group 2 was the lowest at apical part, but there was no statistical difference. The direction of transportation was the outside of curvature at apical part. 2. Centering ratio at the apical part of group 1 was the highest, and there was statistical differences between apical and middle part, apical and coronal part(p<0.05). Centering ratio at the middle part of group 3 was the lowest, and there was statistical difference between apical and middle part(p<0.05). Centring ratio of group 2 was the lowest at apical part, but there was no statistical difference. 3. Amount of dentin removed of group 1 was the highest at coronal, middle and apical part among three groups, and there was statistical difference(p<0.05). 4. The majority of the cross-sectioned canal shape after instrumentation were irregular at coronal, middle and apical part. But there are more number of round shaped canals at group 3 than other group.
