Abstract
OBJECTIVE To evaluate the ultrasonographic features of adenoma malignum, a minimal deviation adenocarcinoma of the uterine cervix. METHODS Eighteen consecutive patients with pathologically confirmed adenoma malignum were enrolled in this study at two institutions. Preoperative ultrasound examination was performed and the results were available in 11 patients. We analyzed retrospectively the gray-scale ultrasound findings for the following morphologic characteristics: cervical enlargement, as well as size, location and ultrasonographic characteristics of lesions. In five patients we also evaluated Doppler features with regard to intralesional vascularity. RESULTS The cervix was enlarged in 73% (8/11) of cases. The mean greatest tumor diameter was 4.2 (range, 2.5-6.8) cm. In five (45%) cases, the cervix was completely infiltrated by the tumor. At gray-scale ultrasound examination, three (27%) tumors were multilocular lesions, four (36%) were multilocular lesions with solid components and four (36%) were solid lesions. In the multilocular lesions with or without a solid component, locules tended to be 1 cm or less in average diameter (86%, 6/7 cases) and there tended to be 11-20 in number (57%, 4/7 cases). In most (57%, 4/7) cases the locular fluid was homogeneously hypoechoic. Most (75%, 3/4) solid lesions manifested heterogeneous echogenicity. The five (100%) tumors examined with Doppler manifested moderate or abundant color content on color or power Doppler. CONCLUSIONS Adenoma malignum can appear sonographically as solid, multilocular and multilocular solid cervical lesions. Awareness of its clinical and ultrasonographic features might improve diagnosis before surgery.

Abstract
Gelatin-hyaluronate sponge with and without antibiotic and epidermal growth factor (EGF) were prepared and compared. Four types of sponges were applied on the full-thickness dorsal skin defect of Wistar rat. The effects of antibiotic and EGF in gelatin-hyaluronate sponge on wound healing were investigated by light microscopy and image analyzer at postoperative days of 5, 12 and 21. An immunohistochemical technique, employing PC10, a monoclonal antibody against proliferating cell nuclear antigen (PCNA) was applied to wounded tissue sections. The number of PC10-positive cells was very high for the sponge with EGF at postoperative day 5, then gradually decreased with time. Also we found that antibiotics restrained the cell proliferation during the migratory phase. The sponge with both antibiotic and EGF showed good wound healing performances on the whole for a healing period. The epithelium was regenerated fast with EGF-impregnated sponges at day 5, but each sample had nearly the same length of regenerated epithelium at day 12.

Abstract
Sclerosing stromal tumors are rare benign ovarian stromal tumors, which have distinctive clinical and pathologic features. The tumors occur predominantly in the second and third decades and are histologically characterized by the pseudolobular pattern of the cellular and hypocellular areas, marked vascularity, and heterogeneity of the cellular area. We analyzed 7 cases of sclerosing stromal tumors, which showed a typical sonographic appearance. On sonograms, sclerosing stromal tumors were solid and cystic and contained multiple round or cleftlike cysts. Ascites was rare. On transvaginal color Doppler sonograms, sclerosing stromal tumors were very hypervascular in the peripheral solid area and internal intercystic space and showed low-impedance flow. We conclude that sclerosing stromal tumors should be considered in young women with menstrual irregularity who have hypervascular solid and cystic adnexal masses.

Abstract
OBJECTIVE To evaluate the cytologic features of atypical glandular cells of undetermined significance (AGUS) smears following conization through a comparison with adenocarcinoma in situ (AIS) smears. STUDY DESIGN Fifty cervical smears, diagnosed as AGUS based on groups of crowded glandular cells that raised the possibility of AIS, from 38 patients who had conization and 24 AIS smears, histologically confirmed, from 17 patients were reviewed. Subsequent follow-up biopsies or hysterectomies in 38 patients were evaluated. RESULTS Nuclear atypia was a more reliable feature than architectural structure in differentiating postcone effect from AIS on cytology. The predominant cytologic features of the postcone smears were crowded glandular cells with a high nuclear/cytoplasmic ratio and relatively small, hyperchromatic nuclei with rather finely granular and uniformly dispersed chromatin, less distinct nuclear membranes, less frequent mitosis and presence of endometrial-type stromal cells in the background. The architecture of the crowded cells in the postcone smears was sometimes similar to that of AIS. No AIS or high grade squamous intraepithelial lesion histology was encountered in follow-up biopsies or hysterectomy specimens. CONCLUSION The cytologic features distinguishing AGUS from AIS may be helpful in identifying the postcone effect. Since it is important to avoid miscalling the postcone effect as AIS, it is recommended that one check for a previous history of a cone biopsy.

Abstract
Novel cross-linked sponges composed of gelatin/alginate and gelatin/hyaluronate and chitosan/hyaluronate (GH, GA and CH, respectively) were prepared and compared. Six different sponges with or without silver sulfadiazine (AgSD) were applied on the full-thickness dorsal skin defect of Wistar rat. The histology and epidermal wound healing rates of the skin defects were investigated by light microscopy and computerized morphometry 5 and 12 days post-operatively. In our full-thickness wound model (diameter 1 cm), the AgSD-impregnated sponges showed good wound healing performances on the whole. However, there appeared meaningful differences of wound healing between the gelatin-based sponges (GH, GA) and the CH. GH with AgSD was found to show the best wound healing properties as a wound dressing resulting from histological findings and computerized morphometric analysis of epidermal healing.

Abstract
This study was conducted to develop a new sponge type of biomaterial to be used for either wound dressing or scaffold for tissue engineering. We were able to prepare an insoluble matrix composed of gelatin and sodium hyaluronate (HA) by dipping the soluble sponge into 90% (w/v) acetone/water mixture containing a small amount of cross-linking agent, 1-ethyl-3-3-dimethylaminoproplycarbodiimide hydrochloride, EDC. To characterize the sponge, Fourier-transformed infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and Instron analysis were performed. The obtained results indicate that the chemically cross-linked sponge shows a cross-linking degree of 10-35%, a mean pore size of 40-160 microm, porosity of 35-67%, and a tensile strength of 10-30 gf/cm(2). Especially, the porosity measured by image analysis showed a tendency to increase with HA content, resulting in an increased water uptake. The resistance to collagenase degradation in vitro increased for up to 2 days. Silver sulfadiazine (AgSD)-impregnated gelatin-HA sponge was also prepared and compared with conventional vaseline gauze by applying it onto a dorsal skin defect of wistar rat for 5, 12, and 21 days. Histological results showed an enhancement of wound healing in AgSD-impregnated gelatin-HA sponge.

Abstract
OBJECTIVES To evaluate the findings of tetralogy of Fallot in various fetal sonographic views. METHODS We reviewed the fetal sonograms and medical records of 20 fetuses with prenatal diagnosis of tetralogy of Fallot. We analyzed the indications for targeted sonography, the abnormalities seen in various sonographic views, the postnatal echocardiographic and angiographic findings and autopsy findings. RESULTS The most common indication for targeted sonography was an abnormal (n = 12) or inadequate (n = 3) finding on sonographic screening in which the abnormality was most frequently found on the three-vessel view (n = 9). The key pathological features of tetralogy of Fallot were uniformly demonstrated in the ventricular outflow tract, three-vessel and short-axis views. The ductus arteriosus was small in 70% of cases and not identifiable in the remaining fetuses. In three of six fetuses with no identifiable ductus, the ductus was shown to be absent at autopsy. The direction of ductal flow was variable. CONCLUSION The key features of tetralogy of Fallot were always demonstrable in the ventricular outflow tract, three-vessel and short-axis views. The most common reason for referral was the abnormal three-vessel view.

Abstract
OBJECTIVES The aim of this study was to evaluate the efficacy of the follow-up methods and results of atypical glandular cells of undetermined significance (AGUS) detected on cervicovaginal Pap smears. METHODS From May 1991 to December 1996, we have performed 407, 451 cervicovaginal Pap smears, of which 326 patients were identified as AGUS. Of the 326 patients, 268 patients were followed by repeat Pap smears, colposcopy, cone biopsy, or endometrial curettage. RESULTS The incidence of AGUS on Pap smears is approximately 0.08%. The mean age of the patients was 43 years (range 22-79 years). The most common complaint was abnormal vaginal bleeding. The gross findings of the cervix were normal to mild erosion. The following past histories of patients could affect the AGUS results on Pap smear: 30 had cone biopsy, 21 had Pap smears on pregnancy and within 8 weeks after delivery or evacuation, 3 were on hormonal replacement therapy, 2 had intrauterine devices for contraception, and 5 were undergoing follow-up after treatment of cervical cancer. The benign lesions detected during follow-up periods were 6 microglandular hyperplasia of the cervix, 5 atypical squamous metaplasia of the cervix, 2 cervical endometriosis, 2 tubal metaplasia, 10 cervical myoma, 11 cervical polyps, 9 endometrial polyps, 3 uterine myoma, 1 pelvic endometriosis, 1 ovarian endometriosis, and 4 uterine adenomyosis. The premalignant or malignant lesions of the cervix were 4 low-grade squamous intraepithelial lesions, 24 high-grade squamous intraepithelial lesions, 8 glandular atypia/dysplasia, 5 adenocarcinoma in situ, 3 microinvasive adenocarcinoma, and 4 invasive adenocarcinoma. The neoplastic lesions of the uterus were 6 endometrial hyperplasia, 11 endometrial adenocarcinoma, 1 malignant mixed Müllerian tumor, and 1 metastatic endometrial adenocarcinoma. Sixty-seven (25%) of 268 patients followed up were identified as having clinically significant lesions of the cervix or uterus. The detection rates of abnormal lesions were 3.1% with repeated Pap smears (3/98), 28.4% with colposcopic-directed biopsy (31/109), 63.6% with cone biopsy (35/55), and 29.7% with endometrial curettage (19/64). CONCLUSION AGUS on Pap smears showed various benign and malignant lesions of the cervix or uterus. The clinicians must communicate with the pathologists regarding the patient's clinical information as well as the origin of the atypical glandular cells in Pap smears. We recommend that patients with AGUS on Pap smear should undergo immediate intensive diagnostic studies, including colposcopic-directed biopsy with endocervical curettage or cone biopsy, to detect cervical lesions and endometrial curettage to detect endometrial lesions.

Abstract
An absorbable sponge, composed of gelatin and alginate, was prepared by new crosslinking method that improved the efficiency of crosslinking. The crosslinking degree was characterized by trinitrobenzenesulfonic acid (TNBS) assay. A water uptake ability test, in vitro drug release and collagenase degradation tests, and an in vivo animal test were employed to confirm the applicability of this gelatin-alginate sponge as a wound dressing material. As the alginate content in the sponge increased, the porosity increased, resulting in an enhanced water uptake ability. Sponges loaded with silver sulfadiazine or gentamicin sulfate slowly released drugs for up to four days. The crosslinked sponge resisted in vitro collagenase digestion for up to three days. An in vivo animal test using witar rat showed rather good wound healing effect of gelatin-alginate sponge containing AgSD than vaseline gauze in our full-thickness skin defect model.

Abstract
The occurrence of malignant mural nodule in benign cystic common epithelial tumor of the ovary have been reported in only three cases; the case one was mucinous cystadenoma with a mural nodule of fibrosarcoma and the others were of carcinomas. Our case was another rare case of ovarian mucinous cystadenoma with mural nodule of anaplastic carcinoma in a 42-year-old woman. The cystadenoma had an unilocular cystic cavity and a mural nodule with thick multinodular solid wall. The internal cystic wall was lined with mucinous cystadenoma without any malignant features. The mural nodule showed anaplastic carcinomatous differentiation and its nature was confirmed by immunohistochemistry and electron microscopy. This tumor had metastasized to the right salpinx, uterus, cul-de-sac, periureter and mesentery.

Abstract
PROBLEM To determine the expression of vimentin and cytokeratin in eutopic and ectopic endometrium of women with both adenomyosis and ovarian endometrioma and to evaluate their cyclic changes during the menstrual cycle. METHOD OF STUDY Twenty patients requiring hysterectomy with salpingo-oophorectomy were studied by immunohistochemistry according to their menstrual cycles. RESULTS Cyclic expression of vimentin was noted in eutopic endometrium and adenomyosis, but not in endometrioma. Cytokeratin expression did not change during the menstrual cycles. The mean intensities of epithelial vimentin were significantly different from each other, being the lowest in endometrioma, intermediate in adenomyosis, and the highest in eutopic endometrium. There was no significant difference in intensities of cytokeratin between adenomyosis and endometrioma, but these intensities were significantly lower than that of eutopic endometrium. CONCLUSIONS Lower intensities of cytokeratin in adenomyosis and endometrioma than in eutopic endometrium suggest that the ectopic endometria may have a lower degree of differentiation regardless of the site. The lower intensity of epithelial vimentin in endometrioma than in adenomyosis during the proliferative phase may reflect decreased functional activity, probably because of a pressure effect on the lining epithelium within the endometrioma.

Abstract
BACKGROUND A new class of topical receptor-selective acetylenic retinoids, the first of which is tazarotene, has been developed. OBJECTIVE Our purpose was to compare the safety, efficacy, and duration of therapeutic effect of 12 weeks of once-daily tazarotene 0.1% and 0.05% gel with that of twice-daily fluocinonide 0.05% cream in the treatment of patients with plaque psoriasis. METHODS Three hundred forty-eight patients with plaque psoriasis were enrolled and 275 patients completed a multicenter, investigator-masked, randomized, parallel-group clinical trial. RESULTS Both tazarotene gels were as effective as fluocinonide in reducing plaque elevation after 1 week of treatment, and tazarotene 0.1% gel was similar to fluocinonide in reducing scaling of trunk/limb lesions at all study weeks except week 4. Tazarotene 0. 1% gel was similar to fluocinonide in reducing scaling of knee/elbow lesions at weeks 8 and 12. Fluocinonide had a significantly greater effect on erythema than tazarotene at weeks 2 through 8. However, treatments were not significantly different at week 12, and tazarotene demonstrated significantly better maintenance of therapeutic effect after cessation of therapy. CONCLUSION Tazarotene 0.1% and 0.05% gels were safe and effective in the treatment of mild-to-moderate plaque psoriasis.

Abstract
Deficiencies of Leu-8 and CD7 antigens are exhibited by CD3+ T cells in the skin lesions of most patients with mycosis fungoides/Sézary syndrome. To determine whether these antigenic abnormalities are limited to involved skin, we studied Leu-8/CD7 expression in 21 skin lesions of mycosis fungoides/Sézary syndrome obtained from 16 patients and compared them with their peripheral blood leukocytes obtained concurrently. There was no correlation between Leu-8/CD7 values in skin lesions versus blood. Blood values were relatively uniform; most patients had 50% or greater of CD3+, Leu-8+ T cells and CD3+, CD7+ T cells. In contrast, skin values were highly heterogeneous; most patients lacked expression of Leu-8 or CD7 by the majority of lesional CD3+ T cells. Furthermore, Leu-8/CD7 antigen deficiency was present in lesional skin in one patient with mycosis fungoides but not in her concurrently sampled pityriasis lichenoides chronica or blood. These findings suggest that Leu-8/CD7 antigen deficiencies in skin lesions of mycosis fungoides/Sézary syndrome do not represent generalized antigenic abnormalities of CD3+ T cells in other body compartments and that within the skin, these deficiencies are disease specific within individual patients with more than one dermatosis. Comparative peripheral blood immunophenotyping of the patients with mycosis fungoides/Sézary syndrome and of the control subjects indicated that the control ranges of CD3+/Leu-8+ and CD3+/CD7+ T cells (33% or greater) extend lower than reported previously (60% or greater) and suggested that leukemic involvement in patients with mycosis fungoides/Sézary syndrome may correlate with percentages of CD3+, Leu8+ and/or CD3+, CD7+ T cells that fall below the revised control range.

Abstract
This study suggests that cross-reactive tumor-associated antigens (TAA) are induced in the epidermis of mice exposed to subcarcinogenic doses of ultraviolet radiation (UVR). Foot-pad immunization of C3H mice with viable epidermal cells from syngeneic UVR-exposed mice induced cytotoxic cells in the draining lymph nodes (DLN). These cells were capable of lysing a battery of UVR-induced tumor targets in a short-term chromium release assay. In contrast, the DLN cells of mice immunized with epidermal cells from normal non-UVR-exposed mice did not mature into effector cells with antitumor activity. The spectrum of tumor recognition of cytotoxic cells induced by immunization with UVR-exposed epidermal cells was identical to that of cytotoxic T cells obtained from animals that were foot-pad immunized with UVR-induced tumor cells. Both cytotoxic cell populations were shown to lyse tumors of diverse origin, including syngeneic UVR- and methylcholanthrene-induced tumors, as well as allogeneic UVR-induced tumors. These cells displayed minimal lytic activity against YAC-1 lymphoma cells, peritoneal exudate cells, and concanavalin A-stimulated splenocytes. The results from this study demonstrate that antigens are expressed on UVR-exposed mouse epidermal cells prior to the emergence of skin tumors, and these antigens can induce cytotoxic cells with specificity for TAA. We conclude that the early antigenic changes observed in UVR-exposed epidermis and their effect on the host's immune system may influence the emergence and progression of UVR-induced skin cancers.

Abstract
Herpes simplex virus (HSV) infection of the lung and lower respiratory tract has been thought to be a rare and fatal disease, usually in patients with immunosuppression, severe burns, or prolonged intubation. However, recently, increasing numbers of patients have been reported to have a localized infection and some of them have recovered without specific therapy. In Korea, there has been yet no proven case of HSV infection of the lower respiratory tract. Recently, we saw a case of localized HSV infection of the tracheobronchus. A 78-year-old male patient was admitted in acute respiratory failure, with COPD and old pulmonary trberculosis. After the clinical condition improved, a bronchoscopy was done which revealed a localized area of swelling, hyperemia, and mucosal irregularity at the lower trachea and right upper lobar bronchus. Bronchial brushing and biopsy showed typical cytologic changes including intranuclear inclusion body. Viral culture of a bronchial washing revealed a growth of HSV, type I. The patient died of unrelated, acute myocardial linfarction.

Abstract
Human neutrophils released the granule constituents myeloperoxidase and lysozyme, but not the cytoplasmic enzyme lactic dehydrogenase, when pretreated with cytochalasin B and stimulated with purified human C5a. Prior exposure to C5a before the cytochalasin B, however, abrogated the subsequent secretory process. Interaction of neutrophils with C5a was shown to result in a concentration-dependent rapid desensitization that could not be overcome by later addition of cytochalasin B or of cytochalasin B and C5a. The effect was relatively stimulus specific in that neutrophils desensitized in this manner could be induced to release granule enzymes by casein or by complement-coated zymosan particles. Cytochalasin B effects on neutrophils appear to mimic those of surface binding of soluble stimuli such as C5a and immune complexes. It is suggested that desensitization in concert with surface stimulation may represent an important intracellular mechanism for limiting neutrophil secretion.
