The transition from preinvasive to invasive disease is a crucial juncture in the development of cervical cancer. The clinical experience that microvasive lesions carry a better prognosis justifies a sepetate diagnostic category. Besides clinical and cliagmostic problerns, the rnicroinvasive cervical cancer presents morphological peculiarities. To investigate the clinieal and pethological aspects of micrenvasive eervical carcinornn, a retrospective study was made on 40 cases, histologically reconfirrned surgical specimens, which had been treated during the period from March, 198I3 to March, 1992 at, Departrnent of Obstetrics and Gynecology, Pusan Paik Hospital, Inje University. The results obtained were as follows ; 1. Mean age of 40 patents was 44.6 year old, all were rnultipatous. Nineteen cases helonged to I s, and 21 cases to I a2. 2. Main presenting symptoms were leukorr hea and/or genital bleeding and the majority of patients showed cervical erosion on groas finding, 3. The corresponding rate of Pap, smear to histologic diagnosis was approximately 67.5%, However, corresponding rate within one histologie grade was about 85%. 4, Aecording to the eolpuacapie examination, less than half of the examined cases revealed suspected abnormal findings suggeeting invasive lesion. 5. As to the reports of punch biopsy, 64.8% of cases showed microinvasive and/or inuasive lesian. With additional diagnostic conization of cervix, the preoperative diagnosis were correct in 82.5%. 6. Histopathological reevaluatin ef surgiral specimens revealed positive correlation between depth of stromal invasion and width of leaior, confluent growth pattern, numher of invasive foci, and invasion of capillary-like spaee, respectively.

This study aimed to evaluate the effect of seminal vesicle fluid (SVF) on the acrosome reaction (AR) occurred spontaneously or induced by Ca2+ ionophore A23187, follicular fluid, and progesterone in mouse epididymal sperm. SVF was divided into high (MW>10 kM)) and low (MW<10 kD) fractions by ultrafiltration. The low MW fraction of SVF decreased the rate of spontaneous AR, however the high MW fraction did not. It suggested that the low MW fraction of SVF might have contained decapacitation factor(s) responsible for prolonging of time need for capacitation. When sperm preincubated for 60 min in the presence of SVF, the rate of AR induced by A23187 was decreased, but prolongation of preincubation time for 120 min significantly potentiated the AR by A23187. It suggested that addition of SVF into sperm preincubation medium imposed the epididymal sperm a condition similar to ejaculation. AR induced by human follicular fluid or progesterone was also inhibited by SVF. It suggested that substance in SVF might have affected AR of mouse sperm by inhibiting the interaction between AR inducing ligands and sperm surface receptors involved in acrosomal exocytosis.

BACKGROUND: Intracellular calcium overload is a common final feature of the ischemic-reperfused heart and mediates the genesis of irreversible cell damage. Reactive oxygen medabolites have been known to play and important role as toxic mediators in myocardial injuries resulting from ischemia and reperfusion. In order to investigate the mechanism of intracellular calcium accumulation in the ischemic-reperfused myocardium, the present study observed the possible contribution of the reactive oxygen metabolite to the calcium transport of cardiac mitochondria. METHODS: Mitochondrial were isolated from rabbit hearts. The effects of a reactive oxygen metabolite, H2O2 on calcium uptake and release, redox states of endogenous pyridine nucleotides and glutathiones of mitochondria respiring with succinate were observed. Calcium uptake and release were monitored by dual-wave length spectrophotometer using a calcium indicator, arsenaze III. Contents and redox states of pyridine nucleotides and glutathiones were measured by enzymatic methods using spectrofluorometer and HPLC. RESULTS: Hydrogen peroxide(10-500microM) promoted calcium release dose-dependently from CA++-preloaded mitochondria, but did not affect the mitochondrial calcium uptake. The H2O2-induced calcium release was accompanied by simultaneous oxidation of the pyridine nucleotides and decrease in the content of the reduced form of glutathione(GSH). When mitochondria were treated with BCNU(N,N=bis(2-chloroethyl)-N-nitrosourea) to inhibit glutathione reductase and so as to reduce the GSH content, there were no increase in calcium release from the mitochondria. These results may indicate that H2O2 increases the permeability of cardiac mitochondrial membrane to calcium in association with the changes in redox state of endogenous pyridine nucleotides, but not with that of glutathiones. CONCLUSION: It is suggested that the reactive oxygen metabolites induce the release of calcium from mitochondria by altering the redox state of pyridine nucleotides, and it may partly be involved in the elevation of cytosolic calcium concentration in the ischemic-reperfused myocardial cells.

A 26-year-old man presented with a 7-month history of hyperkeratotic skin lesions on both elbows and heels. He also had marked subungal hyperkeratosis and splinter hemorrhage on the finger and toe nails. A biopsy specimen from the elbow revealed lichenoid re-actions with areas of epidermal atrophy with alternating acanthosis and foci of parakeratosis. We made a diagnosis of keratosis lichenoides chronica based on the characteristic clinicopathologic findings. We have treated the patient with etretinate, but only the skin lesions on the elbows and heels responded to treatment.

Atypical condyloma is a variant of flat condyloma characterized by the presence of atypical koilocytes having large hyperchromatic, smudged and often bizarre nuclei. Atypical condyloma can be frequently misdiagnosed on cytologic smear and on tissue sections by its marked cellular atypia, as high grade dysplasia, in situ or even invasive squamous cell carcinoma. We described two cases of atypical condyloma of the female genital tract. The cytologic features and histologic changes were reminiscent of those of invasive squamous cell carcinoma and severe degree of dysplasia of the uterine cervix. The differential findings between atypical condyloma and squamous cell carcinoma were discussed in detail.

The giant intra-articular osteochondroma of the knee is very rare and is probably result of synovial metaplasia of the fibrous capsule or of the adjacent connencive tissue of a joint, and of the fragment of articular cartilage. The gross findings and histology are consistent with the osteochondroma. The authors experienced a case of giant intra-articular osteochondroma of the right knee in a 19 years old man who had history of knee injury when he was 16 years old. The mass was excised and the symptome was relieved.

This study was carried out to determine the accuracy of Doppler echocardiography for predicting the pulmonary arterial pressure from right ventricular systolic time intervals in 52 patients with ventricular septal defect. The diagnosis of ventricular septal defect was made by cardiac catheterization and angiocardiography at Dong San hospital, Keimyung University during the period of one year from jan. 1988 to Dec. 1988. Doppler measurements of acceleration time (AT), right ventricular ejection time (RVET), right ventricular preejection period (RPEP), AT/RVET, and RPEP/AT were compared with pulmonary arterial pressure (PAP), measured by cardiac catheterization. The patients were divided into 3 groups : PAP< or =30mm Hg, PAP 31-59mm Hg, PAP??0mm Hg. The following results were obtained. 1) In the groups of PAP< or =30mm Hg, AT was 0.12+/-0.01sec, AT/RVET was 0.47+/-0.07 and RPEP/AT was 0.50+/-0.05. 2) In the groups of PAP> or =60mm HG, AT was 0.06+/-0.01sec. AT/RVET was 0.28+/-0.05. RPEP/AR was 1.51+/-0.21. As the level of PAP increased, Doppler AT, AT/RVET and RPEP/AT showed significant change(P<0.001). 3) The Doppler AT showed relative high correlation(r=-0.76) with PAP measured by cardiac catheterization in all group. 4) The Doppler AT/RVET showed correlation(r=-0.70) with PAP. 5) The Doppler RPEP/AT showed high correlation(r=0.91) with PAP. The Doppler echocardiography was easy to apply in all age groups, and was found useful for detecting pulmonary hypertension in ventricular septal defect and for the follow-up check of the patients. It may help to determine the optimal time for surgery and evaluation of the treatment.

PURPOSE: In mammals, alphaand beta-defensins are antimicrobial peptides that are expressed in various epithelial and phagocytic cells. Human beta-defensin-1 and -2 (hBD-1, hBD-2) have recently been shown to be expressed in various epithelial cells. Vaginal mucosa can be a target of vaginitis and the site of uropathogens' colonization that precedes urinary tract infections. Therefore, innate host defense mediators like antimicrobial peptides in the vaginal mucosa are important. Estrogen and progesterone receptors have been shown to be expressed in the vaginal squamous epithelium. Sex hormones like estrogen and progesterone may cause vaginal atrophy or susceptibility to uropathogens. So, we performed this study to investigate the expression patterns of hBD-1 and -2 mRNA in vaginal squamous epithelium (VSE) with using lipopolysaccharide (LPS), 17beta-estradiol and progesterone. MATERIALS AND METHODS: Normal VSE cells that were retrieved from vaginal tissue during vaginoplasty were primarily cultured in keratinocyte growth medium and they we allowed to undergo their 3rd passage. Modulation of the expressions of hBD-1 and -2 mRNA by various stimuli (LPS 0.5microgram/ml, E2 2nM, P 1micrometer) was measured by semiquantitative reverse transcription polymerase chain reaction (RT-PCR). RESULTS: HBD-1 and -2 were constitutively expressed in the normal VSE cell lines, but the hBD-2 expression was not significant. A marked increase of the constitutive expression of hBD-2 mRNA was observed upon stimulation with LPS, but not upon stimulation with E2. A moderate decrease of the constitutive expression of hBD-2 mRNA upon stimulation with LPS was observed with administering progesterone. CONCLUSIONS: These expressions of hBD-2 mRNA may have important roles in the innate host defense of the urogenital area. Artificial intake of progesterone may lead to susceptibility via a decrease of defensins.
