Development of drug resistance in tumors during treatment is a major factor limiting the clinical use of anticancer agents. When tumor cells acquire resistance to anticancer drug, they show cross-resistance to other antitumor agents. In the present study, SNU-1 cell was induced adriamycin 10-7 drug resistance, SNU-1/ADR, in vitro culture system. We got the doubling time and number for viability test during 96 hours by MTT assay. To investigate the cross resistance of various anticancer drugs in human stomach cancer cell SNU-1 and SNU-1/ADR, We compared IC50 (drug concentration of 50% reduction) and the relative resistance (RR). SNU-1/ADR was expressed multidrug resistant with vinblastine (RR;>31.62), vincristine (RR;29.50), dactinomycin (RR;21.37), epirubicin (RR;17.78), daunorubicin (RR;14.12), adriamycin (RR;7.76), and etoposide (RR;4.46), and other drugs, 5-fluorouracil, cisplatin, cyclophosphamide, methotrexate, and calarubicin, have not cross resistant with adriamycin. There was double minute chromosome in SNU-1/ADR by karyotyping although this change was not seen in SUN-1.

It is well known that anatomic variations affecting the ostiomeatal unit (OMU) become one of the causes of mucosal abnormalities of paranasal sinuses (PNS). Findings of coronal plane CT scans of PNS were analyzed in 95 patients with sinusitis or sinusitis-like complaints. Anatomical variations were seen in 88 cases of 60 patients. Mucosal abnormalities were seen in 27 of 47 cases with concha bullosa, 23 of 37 cases with enlarged ethmoid bulla, 8 of 33 cases with Agger nasi, 20 of 26 cases with nasoseptal deviation, 7 of 8 cases with Haller cell, 3 of 6 cases with duoble middle turbinate, 4 of 6 cases with medially bent uncinate process, 1 cases with laterally bent uncinate process, and 33 of 40 cases with mixed variations. Mucosal abnormalities in cases with antomical variations were detected in 61 cases, including maxillary sinus(51 cases), anterior ethmoid sinus (26 cases), frontal sinus (4 cases), and mixed (32 cases). Mucosal abnormalities without anatomical variations were detected in 13 cases involving maxillary sinuses (7 cases), anterior ethmoid sinuses (5 cases), and frontal sinus(1 cases). In conclusion, as coronal plane CT scan has the capability of dolineating anatomical variations and mucosal abnormalities of PNS, it is considered useful in evaluating the treatment and prognosis of chronic or recurrent sinusitis.

PURPOSE: In patient with blunt trauma of chest, supine AP x-ray cannot differenciate the lung contusion, laceration, atelectasis, and hemothorax definitely. Therefore, computed tomographic evaluation is needed for accurate evaluation of the injuries. In our knowledge, there are few reports about CT findings of blunt chest trauma, in our country, therefore we tried to fiud the characteristic CT findings in patients with blunt trauma. MATERIALS AND METHODS: We analyzed the plain x-ray and CT image of 4 patient with blunt chest trauma. Location and morphology of lung parenchymal contusion and laceration, hemopneumothorax, chest wall injuries and location of chest tube. RESULTS: Lung parenchymal contusion was noted in 53 segments. of 16 patiants'infiltration(n=27 segment), and multiple nodular pattern was noted in 15 segment, pattern of consolidation along the lung periphery was seen in 11 segment. Laceration was noted in 18 lesion and most commonly located in paravertebral area(b=8). CONCLUSION: CT scan of chest in patient with blunt chest trauma, provides accurate informations of the pattern of injuries, and localization, therefore, should be performed as po9ssible.

461 cases of renal biopsy specimens were summerized correlated with their light microscopic and immunofluorescence findings, which obtained from Jan. 1981 to Jul. 1986 at Department of Pathology, Kyung Hee School of Medicine, The results were as follws: 1) The incidence of IgM nephropathy was about 5.8% of the primary glomerulopathy. 2) Sex distribution showed male preponderance with male: female ratio of 1.7:1. 3) Age distribution were 0-9 years 7.4%, 10-19 years 29.6%, 20-29 years 37.0%, 30-39 years 7.4%, 40-49 years 7.4% and 50-59 years 11.1%. 4) The clinical symptoms were gross hematuria 7.4%, microscopic hematuria 59.2%, proteinuria (nonnephrotic) 37.0%, nephrotic syndrome 55.5%, hypertension 7.8% and edema 59.2%. 5) 9 cases (33.3%) had past histories of upper respiratory infections. 6) The distributions of the light microscopic deagnosis were minimal histologic change 11 cases (40.7%), focal glomerulonephritis 7 cases (25.9%), measangial proliferative glomerulonephritis 5 cases (18.5%), focal and segmental glomerulosclerosis 1 case (3.7%) and poststreptococla glomerulonephritis 1 case (3.7%). 7) Immunofluorescence study showed significant diffuse mesangial granular deposits of IgM and C3 in all of the 27 cases. 8) It was demonstrated that in the patients with nephrotic syndrome, the prognosis for the patients with IgM deposition were less favorable than those without IgM deposition.

A 52-year-old woman with esential mixed cryoglobulinemia (type II ), which was confirmed by cryoglobulin elcct,rophoresis and immunofixation elect,rophoresis, had purpuric skin lesions on the legs. The lesions had a tendency of recurrence for the past 2 years, and moderate degrees of arthralgia and myalgia were accompanied in each time. However, the patient had not been suffered from any internal organ distress caused by the disease proress. Histological examinations of a skin lesions revealed a feature of leukocytoclatic vasculitis, and deposits of IgM, IgG and C; were also recognized. A regimen of small doses of prednisolone was effective for the cutaneous lesions in this patient for 4 months follow-up until this writing. It, seems that the patient has had a mild form of the disease among the clinical spectrum of mixed cryoglobulinemia, with a cryocrit value of 2.4% at the time of her initial visit..

Eccrine angiomatous hamartoma is a distinct developmental anomaly showing, histologically, hyperplasia of eccrine sweat apparatus and of vascular elementa in the same lesion, and clinically, the angiomatous lesions with occasional tenderness and profuse local sweating. Recently, we examined an 18-year-old, otherwise healthy girl having, on the anterior aspect of the right leg, an extensive, irregularly marginated and somewhat bluish, tender, firm subcutaneous mass. The mass was studded with several overlying macular, verrucous or nodular angiomatous patches which showed conspicuous hyperhidrosie. Histological examination revealed marked hyperplasia, hypertrophy and cystic dilatations of eccrine sweat apparatus accompanied by proliferation of the capillary hemangiomatous component and ectopic, thick smooth muscle bundles in the deep dermis and subcutaneous tissue.
