Because the postmortem changes rapidly distort values of many constituents in the body fluids, the determination of postmortem chemical changes and relation among body fluids is very important in medicolegal community. A laboratory result is not useful if appropriate data for comparison are lacking. The aim of this paper is to determine the reference ranges and the postmortem changes for chemical constituents in postmortem specimen. We examined 17 clinical laboratory parameters in cadaveric blood and vitreous humor obtained from 51 autopsy cases. The mean, standard error, standard deviation and confidence interval of all measured constituents were shown in Table 2 & Figure 1. The postmortem blood level of amylase, phosporus, LDH, ALT, AST and CPK are very higher than those of antemortem blood. The postmortem vitreous level of total bilirubin, triglyceride, GGT, alkaline phosphatase, albumin, total protein and cholesterol are very low and is not reliable. The ratio of vitreous/blood in calcium, BUN, creatine and uric acid are 0.74, 0.68, 0.29 and 0.23 in decreasing orders(Table 3,4). For the medical examiner or pathologist, routine chemical examinations of the vitreous humor can provide evidence of abnormality not apparent in gross or microscopic examination of the tissue. A more extensive study will be required, using a larger number of subjects, to establish the full range of variability.

This case report describes a patient with semipedunclated granuylar cell tumor(granular cell myoblastoma) of the proximal ascending colon removed by endoscopic polypectomy. A 39-year old femalie was visited to our hospital for intermittent abdominal pain and loose stool. Colonoscopic examination showed a semipedunclated lesion covered with yellowish white smooth mucosa in the proximal ascending colon. The tumor was removed by endoscopic polypectomy. The collected specimen was 0.9x0.8 cm in size. The cut surface of the specimen showed a white round firm tumor covered with mormal epithelium of the colon. Using immunohistochemical study, the tumor cells were to be positively stained by S-100 protein and negatively stained by desmin, which supports the concept of the Schwann cell origin of granular cell tumor. In Korea, 2 cases of granular cell tumor of the colon and rectum, which were treated by surgical removal, have been reported. This case in the first endoscopic polypectomy of granular cell tumor of the colon and retum in Korea. The endoscopic polypectomy is thought to be useful for the therapy of small pedunclated or semipedunclated granular cell tumor, intracolonic type.

The authors developed a computerized documentation system to record and store all the data pertaining to an endoscopic examination of the upper digestive tract. The system was programmed using the database management system Clipper Version 5.01. It is easy and convenient to use due to advanced deaign of input screen using menu bars and pull down menu and windows. The system was designed to permit the easy storage and retrieval of data by personnel who lack computer skills and who may only have limited typing ability. Today this system has been in daily use for 1 year at the endoscopic units of 8 different branch hospitals of Catholic university,medical college. Overall the experience in these centers has been positive, with excelient or good participation. Characteristics of this system are a menu-driven system, data input by predefined list, instantaneous report generation, on line access to previous examination, late entry of yathologic regerts. and record retrieval, listing according to different criteria. For the description of endoscopic findings and diagnosis, structured input is maintained. All of the findings are chosen from predefined list using pop-up screen and also free text typing is allowed. Therefore time effort was not increased compared to conventional documentation. Structured input and the resulting categorical data affer several advantages.

Atropine is the classic antimuscarinic anticholinergic drug that bas been used to block cholinergic neurotransmission in basic research and received recent interest clinically in the intracavernous pharmacotherapy of erectile dysfunction. It has been suggested that at low dose(0.00000001M), atropine blocks muscarinic receptors, thereby reducing both cholinergic of the adrenergic and cholinergic excitation of the NANC neuroeffector systems, on the other hand, at large pharmacological dose(0.001M),induces the release of EDRF which recently has been identified as nitric oxide(NO) or NO like substance. Therefore, we tried to confirm the action of atropine in the cavernosal tissue and define its mechanism. Strip of rabbit corpus cavernosum were isolated and mounted in 10 ml organ chambers to measure isometric tension. Muscle strips submaximally precontracted with phenylephrine(5x0.000001M) and treated with increasing concentrations of atropine(0.00000000001M to 0.00lM) showed tension increase upto 0.00000001M of atropine, and thereafter, relaxed concentration dependently(0.0000001M: 43.7%, 0. 000001M: 63.0%,0.00001M:86.2%,0.0001M:93.6%,0.001M:100%). Relaxations to atropine(5x0.000001M) were not inhibited even partially by endothelial disruption or by pretreatment with methylene blue or pyrogallol. Pretreatment of muscle strips with atropine(5x0.00000lM) caused concentration- related inhibition of a phenylephrine induced contraction, and in calcium-free high potassium depolarizing solution, decreased basal tension as well as inhibited contraction induced by CaC12. However, atropine did not produce reduction of responses to depolarizing medium(20, 40, 80mM KCl). With these results we can confirm the relaxation effect of atropine at a larger dose(>0.0000001M)on the cavernosal smooth muscle and suggest that its action is mediated by increasing intracellular calcium sequestration,not by hyperpolarization or EDRF.

PURPOSE: To compare the detectability and conspicuity of focal hepatic lesions among conventional spin echo techniqueniques and fast scanning techniqueniques in MR imaging. MATERIALS AND METHOD: 36 patients (24 men and 12 women, mean age of 54 years) with suspected liver mass on CT scan and US underwent MR imaging at 1.5 T system. Conventional spin echo T1, T2 weighted imaging, T2 weighted fast spin echo, T1 weighted fast multiplanar spoiled gradient recalled(FMPSPGR) imaging and Gd-enhanced FMPSPGR(Gd-FMPSPGR) were performed. 16 cases of hepatocellular carcinoma, 13 cases of hemangioma, 3 cases of metastasis, 3 cases of cholangiocarcinoma, and 1 case of lymphoma were included. Lesion conspicuity and number of detected hepatic masses were compared among the MR sequences. RESULTS: Overall 63 hepatic lesions were detected in 36 patients. Lesion detection' was 63(100%) with Gd-FMPSPGR, 62(98%) with non-enhanced FMPSPGR, 58(92%) with SE T2WI, 56(89%) with SE T1WI and 54 (86%)with FSE. For solid tumors, the contrast to noise ratio was greatest on Gd-FMPSPGR which was significantly higher than any other sequences. For hemangiomas it was greatest on SE T2WI and was significantly higher than SE T1WI. In the qualitative assessment, Gd-FMPSPGR was preferred for both solid mass lesion and hemangioma. FSE was inferior to SE T2WI for lesion detection and conspicuity without statistical significance. CONCLUSIONS: For the evaluation of focal hepatic lesions, breath-hold FMPSPGR with and without contrast enhancement may replace the conventional SE T1WI. Because FSE was inferior to SE T2WI when the later is used with respiratory compensation in some cases, it is difficult to replace the SE T2WI with FSE. But FSE, FMPSPGR and Gd-FMPSPGR images, when combined, may replace SE T1WI and SE T2WI.

Antigen-specific T cell activation requires interaction of the T cell with specialized antigen-presenting cells. Signaling through the TCR is necessary but not sufficient to induce antigen-specific T cell activation and cytokine secretion. This first signal, termed signal 1, is both antigen-specific and MHC-restricted. Signal 2, which is neither antigen-specific nor MHC-restricted, is necessary to induce cytokine secretion, cellular proliferation, and effector function. Recently immunological studies in T cell activation area are mainly focused on biological and molecular biological characterization of TCR/CD3 complex and accessary molecules providing costimulatory signal (signal 2). If signal 2 is not delivered, T cell enter a state of long term un-responsiveness to specific antigen-termed anergy. Monoclonal antibody technique has been especially involved in recognizing novel inducible cell surface antigens on T cell activation. This study was aimed to develop monoclonal antibodies recognizing novel cytoplasmic proteins present in activated T cells. We make 6 monoclones involved in changing pattern of T cell activated cytoplasmic proteins. Using these 6 monoclonal antibodies analyze to find novel molecules involved in T cell activation associated response, apoptosis, and/or heat shock response of the T cells in early T cell activation.

Peripheral cementifying fibroma is histomorphologically similar to the central cementifying fibroma, but this lesion is unique to the gingival mucosa and is only rarely seen in edentulous area. In most instances, it arise from interdental papilla, with 80% occurring anterior to molar region. This lesion appears to involve the maxilla and mandible equally, demonstrates the highest occurrence rate during the second decade of life, and affects female more frequently than male, with 4.3:1 to 3:2. Peripheral cementifying fibroma presents as firm, pedunculated or sessile mass with an intact or ulcerated surface depending on the presence of trauma. Microscopically, it reveals a highly cellular mass of connective tissue containing numerous plump, proliferating fibrolasts and several forms of calcification. Effective treatment requires deep excision, which includes the ligament and periosteum, followed by a thorough root scaling of the adjacent teeth. A reveiw of the literature and a report of a case of peripheral cementifying fibroma are presented.
