Purpose: An unexpected inflammatory cecal mass of uncertain etiology was encountered during surgery for presumed appendicitis. In this case, the surgeon couldn't exclude differential diagnosis which were severe appendicitis involving the cecal region, diverticular disease, other inflammatory bowel diseases, and neoplasm. Therefore, this finding leads to a therapeutic dilemma for the surgeon, when making surgical decisions during the operation. The aim of this study was to resolve this dilemma, a retrospective review was undertaken in this study. Methods: A retrospective study was performed to review the management of this problem at Soonchunhyang University Chunan Hospital for eight and half years from July 1991 to December 1999. A review of the emergency operation records identified 50 patients who had undergone ileocecal resection or right hemicolectomy for an inflammatory ileocecal mass of uncertain etiology when operated on for probable appendicitis. Results: Altogether, 39 patients underwent ileocecal resection, and 11 patients underwent right hemicolectomy. The final pathologic diagnosis was appendiceal abscess in 32 patients (63%), cecal diverticulitis in 7 patients (14%), neoplasm in 6 patients (12%), appendiceal phlegmon in 3 patients (6%), ileal tuberculosis in 1 patient (2%) and Anisakiasis in another patient (2%). The neoplasm of the 6 neoplasm patients was ascending colon cancer for 4 patients and cecal cancer for 2 patients. There was no mortality in this group. Conclusion: Although most inflammatory cecal masses are caused by benign disease, all cases in which the intraoperative diagnosis is unclear, any pathologic diagnosis including neoplasm cannot be ruled out. So this suggest ileocecal resection or right hemicolectomy to remove a possible underlying malignancy, and to decrease morbidity and mortality.

One of the noticeable linguistic characteristics that the patients with apraxia had was that they segmentalized syllables and pronounced articulation longer than others. For this reason, their speech was slower than others on the whole. The subject of this study included 5 patients with apraxia as well as aphasia and 5 patients with aphasia and no apraxia, and the purpose of this study was to analyze the characteristics of segmental sound and rhythm of the patients with apraxia by means of suggesting a stop sound in a form of description and interrogation. Experiment data of this study were limited to one-syllable words and two-syllable words and this study attempted to examine an ability of realizing the rhythm of apraxia by providing them with a stop sound in a form of description and interrogation as well as in a form of ‘CV’ formula and ‘VCV’ formula so as to find out the characteristics of the stop sound according to the phonetic environments. As a result, it has been demonstrated on the whole that the length of acoustic variable in apraxia was significantly longer than aphasia and normal group. Keywords : apraxia of speech (AOS), Aphasia, Stop sound, VOT(Voice Onset Time)

갈색 세포종은 신경내분비종양의 하나로 VIP를 포함한 다양한 신경내분비 펩타이드를 분비할 수 있다. 저자들은 만성 설사와 체중 감소를 주소로 내원한 환자에서 좌측 부신에 VIP를 생성하는 갈색 세포종을 진단하여 성공적으로 제거한 후 증상이 모두 호전된 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Vasoactive intestinal peptide (VIP) is a 28-amino acid peptide, which may cause secretory diarrhea by stimulating the production of adenylate cyclase. Neuroendocrine tumors, secreting vasoactive intestinal peptide (VIP), are almost always of a pancreatic in origin. However, a pheochromocytoma may produce several neuropeptides, containing VIP, as they are considered to be neuroendocrine tumors. A 57-year-old woman, who presented with chronic watery diarrhea, hypokalemia, weight loss and a left adrenal mass, is described. Histologically, the tumor was diagnosed as a pheoch-romocytoma, with ganglioneuronal differentiation, and was histochemically confirmed to produce a vasoactive intestinal polypeptide. A left adrenal VIP-producing pheochromocytoma was successfully resected. After surgery, her diarrhea subsided and the electrolytes, affected neuroendocrine hormone levels, blood pressure and blood sugar level were normalized (J Kor SOC Endocrinol 18:227-231, 2003).

A series of new polyamides containing main chain ethylene oxide unit and alkoxy side chain were prepared using the method of interfacial polycondensation of diamino compounds with 2, 5-didodecyloxyterephthalic acid chloride. The IR spectra of polyamides exhibit each significant NH bond and C=0 bond at ?? and ??. Solubilities of the polyamides are related to length of oxyethylene lingkage. As the length of oxyethylene unit increase, the solubilities increase. Thermal preperties of the polyamides were investigated by differential scanning calorimetry(DSC) and by thermogravimerty analysis(TGA). The Tg are related to length of oxyethylene lingkage. The length of oxyethylene unit increased, Tg of the polyamides was lowere. Tg's of polyamides were detected from 71℃ to 188℃. Initial decomposition temperatures of polyamides were showed from 250℃ to 350℃ in nitrogen atmosphere. These polyamides showed good thermal stability and good solubility.

It is essential that we put the anticoagulant into the blood specimen of the CBC test. However, the value of some parameters in the CBC test can be changed whenever using some anticoagulants. EDTA anticoagulant is mostly used these days. There are 3 kinds of EDTA, that is K_(2-), K_(3-), and Na_(2-) EDTA. The author studies how many effects each the EDTA gets into the true value of blood specimen for MCV of RBCs. Especially we compared the MCV effect of different concentrations of 3 EDTA anticoagulants on the bias with time and instrument. Some results are gotten. In our results, K_(3-)EDTA anticoagulant shows more satisfactory MCV value than K_(2) or Na_(2-)EDTA. On using concentration of EDTA, 1.5㎎ EDTA/㎖ of blood show more satisfactory MCV value than 7.5㎎ EDTA/㎖ of blood. However, the choice of anticoagulant may be dependant on the different instruments.

Multidrug resistance (MDR) of cancer cells is, at least in part, associated with the overexpression of P-gly-coprotein (P-gp). Many studies hve demonstrated that natural compounds obtained from fruits, vegetables, teas and medicinal plants may modulate P-gp activity. The objective of the present investigation was to examine the effect of seven natural compounds on the P-gp activity in human uterine sarcoma cell line, MES-SA/DX5. Daunomycin uptake was significantly increased by biochanin A and silymarin (p<0.0001) whereas it was reduced by morin (p<0.01). The efflux of daunomycin from the cells was significantly inhibited by biochanin A, morin, cephalotaxine, berberine (p<0.05) and silymarin (p<0.0001). Biochanin A, berberine and silymarin significantly decreased IC_(50) value of daunomycin (p<0.05) while morin increased it (p<0.05). These results suggest that some natural compounds such as biochanin A and silymarin may inhibit P-gp funciton and can by developed as MDR reversing agents to improve the efficacy of chemotherapeutic drugs when administered concomitantly.

Background : Because systolic and diastolic dysfunction frequently coexist in acute myocardial infarction (AMI), we hypothesize that a combined measure of ventricular performance using Doppler echocardiography may be more sensitive and time-saving diagnostic tool for the evaluation of patients presenting with cardiogenic chest pain. Method and Results : Seventy-one patients with AMI (47 male, 59±11 years) and 45 patients with normal coronary artery (29 male, 52±11 years) were included in the study for measurement of cardiac performance index and established parameters of ventricular function using conventional echo-Doppler methods. a new derived index of cardiac performance: (ICT+IRT)/ET, was obtained by subtracting ejection time(ET) from the interval between cessation and onset of the mitral inflow velocity to give the sum of isovolumic contraction time(ICT) and isovolumic relaxation time(IRT). The mean value of the index was significantly different between normal and AMI(p<0.01). The degree of inter-group overlap was smaller for the index compared to other parameters. within functional groups, the value of the index did not appear to be related to heart rate, mean arterial pressure and the degree of mitral regurgitation. Conclusion : cardiac performance index is a conceptually new, simple and reproducible Doppler index of combined systolic and diastolic myocardial performance, and it is useful as screening test for patients with cardiac dysfunction due to AMI

J. J. KIM, M. H. LEE, Y. J. KIM, W. S. CHAE, Y. S. HAN, O. KWON. Comparison of the maximum EMG levels recorded in maximum effort isometric contractions at five different knee flexion angles. Korean Journal of Sport Biomechanics, Vol. 15, No. 1, pp. 197-206, 2005. The purpose of this study was to quantify the maximum EMG levels and determine if there are differences in these EMG levels with respect to different knee flexion angles. Eight university students with no known musculoskeletal disorders were recruited as the participants. The maximum voluntary isometric knee extensions and flexions were taken from each participant sat on the isokinetic exercise machine (Cybex 340) at five different knee flexion angles (10?30?50?70? 90?. After surface electrodes were attached to rectus femoris, vastus medialis, vastus laterlis, biceps femoris, and semitendinosus, maximum EMG levels at five different knee flexion angles were measured. The results showed that there was no significant difference in maximum EMG levels among five different knee flexion angles. Although there was no significant difference in EMG levels and were some variations among different knee flexion angles, the EMG signals of quadriceps in extension and biceps femoris in flexion were the greatest at 30? It seems that different joint angles or relative locations of body segments might affect the magnitude of EMG levels. Because the maximum EMG levels could change with a different knee flexion angle, an attempt should be made to more accurately measure these values. If then, %MVIC measure provides more reliable data and is most appropriate for EMG normalization.
