Myxopapillary ependymoma generally arise in the conus medullaris and filum terminale of adult spinal cord. These tumors are readily recognized due to unique histopathologic features, however, their cytologic features are not well described. When only a tiny sample is obtained, cytologic examination using crush preparation may be a useful diagnostic tool to help appropriate intraoperative diagnosis. We present the crush cytologic features of myxopapillary ependymoma arising in thoracic and lumbar spinal cord of a 13-year-old boy. The patient had complained of paraparesis and back pain for 1 month. The MRI image revealed a relatively well demarcated intramedullary mass in T11-L1 levels. Crush preparation for cytology were performed by biopsy material. Crush cytologic findings revealed high cellularity and small sized branching papillary clusters on fibrillary or mucinous background. The tumor cells had uniform round or elongated nuclei. The cytoplasmic process of tumor cells were attached to the vascular wall. Between the tumor cells and vascular walls, the perivascular collar of globoid acellular stroma with metachromatic reaction on toluidin blue stain was noted. The crush preparation of myxopapillary ependymoma is considered as a simple and highly accurate diagnostic tool for differentiation from other intramedullary neoplasms of central nervous system.

Sixteen strains of LT-producing enterotoxigenic E. coli 0128 which were isolated from diarrheal patient's stool in Pusan University Hospital, were serotyped and analyzed for plasmid DNA profile, MRHA of human blood cells, and also tested for possession of LT, ST, aggA, EAST1 genes by the PCR method and analyzed the RAPD pattern. Screening sensitivity for ETEC by salting out test was 87.5%. These data suggest that hydrophobicity test using salting out is rapid, inexpensive, and simple screening test for ETEC. CFAs were identified in 87.5% of strains; 43.75% the strains harbored CFA/I, 43.75% CFA/II, and 12.5% expressed none of these CFAs. For plasmid profiles, 12 strains had 60 MDa plasmid and several smaller plasmids. The strains showed 5 types of plasmid profiles. By PCR, LT gene but not ST gene was detected from all of the 16 strains EAST1 gene was detected from 14 strains. Ten strains could be differentiated to 3 patterns by chromosomal DNA fingerprint. The chromosomal DNA fingerprinting is considered very useful for the epidemiological study.

In an attempt to treat the cold urticaria, a new bradykinin inhibitor, homoclomin was administered orally and effective result were obtained. The urticaria was confirmed by the employing the ice cube test on the patient and the positive reaction was appeared generally 10 sec. to 15 min. after application of ice cube on the forearm. After oral administration for 3 days (40mg/day) clinical symptoms were relieved temporarily and weakly positive or negative reaction observed in repeated ice cube test.
