BACKGROUND: Oncogenes and EGF-Receptor(EGFR) may be involved n different stages of the multistep carcinogenesis process. A specific pattern of karyotypic abnormalities in solid tumors can be detected by cytogenetic methods. OBJECTIVE: This study is intnded to observe the cytomolecular kiologic chracterization of c-myc, erb B and EGFR genes in squasnous cell carcinoma(SCC) of the skin and cervix. METHODS: We have eytogenet,ically examined the short-term culturs from SCC. The rearrangement, amplification or expressi.on of erb B, c-myc, and EGFR genes were studied by Southern blot, analysis of genomic DNA and by slot blot analysis of tota! RNA extracted from biopsies of normal skin and SCC tissues. EGFR expression was examined immunohistochemially using monoclonal antibodies and the localizat,ion of the c-myc oncogene mRNA by in situ hybridization. RESULTS: A remarkably structural aberration was del 6(q21-qter) counted 20 metaphases among 28 metaphases ana1yzed. In nunierical aberration, all chromosomes were lost or gained randomly. Amenploid including triploid and tetraploid were observed in 8 metaphases, 6 tumor cells contained marker chromosome. In Southern blot analysis, rearrangement and amglificaton of EGFR in primary squamous cell carcinoma of cervix uteri and skin respectively. In slot blot analysis, the levels of c-myc, erb B and EGFR mRNA increaaed respectively 3.5, 2.5 and 2.8 times in SCC when compared to normal tissues. In immunoperoxidase stain, EGFR was present, in SCC where keratinocytes with strong cyto-plasmic staining but no membr, line labelling, where as in normal skin the were primarily present in t,he membrane and cytoplasm of basal cells. In situ hybridization with c-myc cDNAs allowed detection of grains representative of biotin labelled cDNA-mRNA hybrids in the frozden section of SCC tissues. CONCLUSION: These results suggest that specific patterns of karyotypir abnormalites, rearrangement, or amplification of EGFR gene, and overexpression of oncogenes and EGFR gene may be associated with the carcinogenesis of SCC.

OBJECTIVE: The authors present the results of management outcomes for upper basilar artery aneurysms via transclinoidal approach. METHODS: Clinical and angiographic evaluations were performed in twenty two consecutive patients with upper basilar artery aneurysms(three of them had superior cerebellar artery aneurysms) treated by surgery via transclinoidal approach between January, 1990 and April, 2000. RESULTS: Of the 22 patients, fifteen patients had multiple aneurysms including basilar bifurcation aneurysms and basilar-superior cerebellar aneurysms. Seventy seven percent were in good preoperative neurological status(H-H grade I-III), 23% were in poor grade(H-H grade IV). The management outcome was:Glasgow outcome scale(GOS) I 54.5%, GOS II 18%, GOS III 13.6%, GOS IV 4.5% and GOS V(death) 9%. The major causes of morbidity were direct brain damage, perforator occlusion, vasospasm and meningitis. CONCLUSION: The management outcome of upper basilar artery aneurysms treated via clinoidectomy was good(72.5%). Transclinoidal approach is an acceptable alternative for upper basilar artery aneurysms.

BACKGROUND: Suction auto epidermal graft for the treatment of stable vitiligo has become popular clinically. In general, depigmented epidermis is removed by liquid nitrogen freezing for preparation of the recipient site. There have been some problems with the nitrogen freezing method, uneven repigmentation, appearance of Koebner's phenomenon on normal colored skin around the graft site, scar formation on recipients sites. In our view these resulted in unwanted damage to the dermis and epidermal and skin appendageal melanocytes of normal skin by freezing. OBJECTIVE: To introduce a method to remove the depigmented epidermis of recipient site with minimal unwanted damage to melanocytes and dermal tissue. METHODS: Using Ellman surgitron, irradiation equipment of 3.8MHz frequency the depigmented epidermis was removed with a blade electrode under rated electric power around 10 watts depending on the thickness of the epidermis. Operating mode was fully filtered current for minimal charring and destruction of tissue through pure micro-smooth cutting. RESULTS: In the case of removal of the epidermis with Ellman surgitron, oozing and inflammation decreased markedly compared with those applied with liquid nitrogen. And it was confirmed histopathologically that there was no significant unwanted destruction of healthy tissue. Moreover, the electrode of Ellman surgitron is designed to be apt to trace the margin of depigmented lesion. And Ellman surgitron features a continuously linear intensity setting for precise, predictable control to minimize tissue destruction and charring. So we were able to remove the epidermis of the shallow lesion looking like a pseudopod and of the thinnest part of the body like eyelid also. And we grafted normal epidermis successfully on the depigmented lesion. CONCLUSION: The removal of depigmented epidermis by radio-frequency gave satisfactory results in the suction auto epidermal graft by overcoming the defects shown as depigmented epidermis which were removed by liquid nitrogen freezing. And this method made patients comfortable because of less pain, a one day operation procedure and good results.

Incarceration of the gravid uterus is a rare but serious complication of pregnancy. Reported is the case of a gravid 2, para 0, abortus 1 with known uterine subserosal myoma(5.3 x5.5cm sized) 26-year-old woman presented with acute dysuria and urinary retention. The patient was 14 weeks and 3 days pregnant and presented several week history of urinary frequency and sensation of incomplete bladder emptying. Examination revealed a retroflexed uterus with cervical opening pointing toward the anterior abdominal wall. An ultrasound revealed a thin, elongated maternal bladder and a uterus incarcerated between the sacral promontary and the pubis. The incarceration was successfully reduced by tenaculum traction of the cervical posterior lip without surgical intervention and had a normal infant of appropriate weight at term.

Cloeortolone (9-a-chloro-6-a fluoro-11-B 21 digydroxy-16 methyl preganl,4-diene) is a newly synthesized corticonsteroid which has been found to have potent antinflammatory action and good tolerance through animal experiment. Several investigators reported its therapeutic affect in various dermatoses by topical application. The present was undertaken to evaluate the therapeutic effect of 0.1% clocortolone cream (Purantix-Sandoz) in patients with eczematous dermatoses and with psoriasis and to compare its effect with that of I% hydrocortisone. Eleven patients with contact dermatitis, 10 with psoriasis entered this study durtin the period of 6 months from January to june, 1977 at the Department of Dermatology, Seoul National University Hospital. All patients were instructed to apply 0.1% Clocortolone cream on one side of their lesion and 1%hydrocortisone cream on the opposite site for two weeks. After wo weeks' period of observation the status of the lesion was evaluated clinically and the tesults were as follows. 1. Ninety one percent of patiens with contact dermatitis, 70% of atopic dermatitis, 60% of nenrodermatitis, 67% of nummular eczema and 60% of psoriasis responded very effectively or moderately effectively. The therapeutic responses were generally similar to that of 1% hydrocortisone. 2. During the ovservation period, there was no systemic of local side effect of 0.1% Clocortolone cream.

This study examined the residue of dl-methylephedrine hydrochloride (MEP) on the muscle of pigs administered orally with MEP 12 g/ton feed for seven consecutive days. Twenty healthy cross swine were administered MEP. Four treated animals were selected arbitrarily to be sacrificed at 1, 2, 3, 4, and 5 days after treatment. MEP residue concentrations in the muscle were determined by liquid chromatography coupled with tandem mass spectrometry. The drug was extracted from muscle samples using 10 mM ammonium formate in acetonitrile followed by clean-up with n-hexane. The analyte was separated on an XBridgeTM hydrophilic interaction liquid chromatography column using 10 mM ammonium formate in deionized distilled water and acetonitrile. The correlation coefficient (R2 ) of the calibration curve was 0.9974, and the limits of detection and quantification were 0.05 and 0.15 μg/ kg, respectively. The recoveries at three spiking levels were 94.5–101.2%, and the relative Standard Deviations was less than 4.06%.In the MEP-treated group, MEP residues on one day post-treatment were below the maximum residue limit in the muscle. The developed method is sensitive and reliable for the detection of MEP in porcine muscle tissues. Furthermore, it exhibits low quantification limits for animal-derived food products destined for human consumption.
