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.

A mesenteric cyst is considered one of the rarest type of abdominal tumor. We have experienced unusual case of large mesenteric cyst arising from jejunum in a 10-year-old boy. CT disclosed cystic intrabdominal mesenteric mass with attenuated coefficiency +3-+11 Hounsfield units (HU). Pathologically it was confiremed to be benign mesenteric cyst.

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.

OBJECTIVE: The prescription rates of long-acting injectable (LAI) antipsychotics are very low around 1% in Korea. This study was aimed to explore the preference of LAIs in patients with schizophrenia, who are currently living in community, and their caregivers. METHODS: The patients, diagnosed with schizophrenia by DSM-IV TR and were registered in the 31 mental health centers of Gyeonggi province and their caregivers were inquired the knowledge of the LAIs. The questionnaires contained information such as demographic characteristics, history of psychiatric treatment, and so on. RESULTS: About 5,318 were registered in 31 community mental health centers of Gyeonggi province in February 2012. The questionnaires of 614 patients and 365 caregivers were gathered from 20 community mental health centers. The mean ages (+/-SD) of patients and caregivers were 41.9 (+/-10.2) and 62.2 (+/-13.4) years old, respectively. 272 patients (44.6%) had experienced the discontinuation of medications without doctor's consent. 217 patients (35.9%) and 97 caregivers (27.1%) knew about the LAIs. The preference rates for LAIs were 35.2% and 46.8% for the patients and caregivers, respectively. CONCLUSION: There is still huge discrepancy between the preference and the real prescriptions of LAIs in community-dwelling patients and their caregivers, much higher than in those of hospital settings. This study suggests that both patients and caregivers registered in the community mental health centers have a strong commitment to live in the community. The obstacles against the benefits of LAIs need to be resolved.

To delineate the coronary anatomy and the left ventricular function during early myocardial infarction, coronary arteriography and left ventriculography were performed prospectively in 28(34%) of 83 patients who were admitted to the coronary care unit at Severance Hospital from November 1983 to August 1984 within 30 days(median : 14 days;range : 4 hours to 30 days) after the onset of symptoms. The frequency of total occlusion of the infarct related artery was evaluated in the time course of infarction. To prove spontaneous recanalization, 3 patients who had total coronary occlusion underwent serial study within 11-20 days after the first study. We categorized the patients into two comparable groups according to the infarction site, coronary angiographic findings, and age. Comparison of clinical and angiographic findings between each group was made. The following results were obained. 1) There were 23 patients with transmural myocardial infarction(82.1%) and 5 with nontransmural infarction(17.9%). Among 23 patients with transmural infarction, 14 had anterior infarction(60.9%) and 9(39.1%) inferior infarction. 2) The mean age was 51.3 years(range : 31-79 years). The ratio of male to female was 3.7:1. 3) Fifteen patients(53.6%) had one-vessel disease, 10(35.7%) two-vessel disease and 2(7.1%) three-vessel disease, One patient(3.6%) had insignificant disease(less than 50% reduction in luminal diameter). Nontransmural infarction had a tendency to be associated with higher prevalence of multivessel disease than transmural infarction(80% vs 34.8%). 4) In 23 patients with transmural infarction, 12(52.2%) had complete occlusion and 11(47.8%) incomplete occlusion of the infarct related artery. Three patients(13.0%) had subtotal occlusion(90-99%) and 4(17.4%) had lesions of 70-89% luminal diameter narrowing. Three patients(13.0%) had 50-69% lesions and the remaining 1(4.4%) had insignificant obstructive lesions. 5) Of the 23 patients with transmural infarction, 12 were studied within 14 days and 11 in 15-30 days after the onset of symptoms. The frequency of total coronary occlusion was significantly higher in the patients studied within 14 days of symptom onset vs those studied in the 15-30 days period(83.3% vs 18.2%;p<0.001). Serial studies of 3 patients with total coronary occlusion at the initial study demonstrated occurrance of spontaneous recanalization in 2 patients. 6) The left ventricular-ejection fraction was higher in the patients with nontransmural infarction, inferior infarction, and incomplete coronary occlusion(65+/-14%, 58+/-16% and 57+/-17%) than that of the patients with transmural infarction, anterior infarction, and complete coronary occlusion(51+/-15%, 47+/-14% and 46+/-13, p<0.05). But there was no significant difference in left ventricular ejection fraction between the young(<45 year) and the old(> or =45 year) age groups. And also 0-1 vessel disease and 2-3 vessel disease groups did not show significant difference in ejection fraction. The degree of congestive heart failure was more severe in the patients with anterior infarction than in those with inferior infaction. multi-vessel disease group was significantly older than 0-1 vessel disease group(55+/-8 yrs vs 46+/-12 yrs, p<0.05), and the young age group had a tendency to be associated with higher prevalence of single vessel disease. 7) As for the complications of angiocardiography in this study, there was ventricular finbrillation in 2 patients(7.1%) without mortality. It is concluded that coronary arteriography can be safely performed within one month after acute myocardial infarction;high prevalence of one-vessel disease in acute myocardial infarction in the Korean adult patients admitted to a general hospital;lower incidence of total coronary occlusion in the late time course of infarction due to spontaneous recanalization;better left ventricular function in the patient groups with nontransmural infarction, inferior infarction and incomplete coronary occlusion.
