The present study was designed to elucidate the effects of rostral basal forebrain lesions on neuropeptide containing neurons in the cerebral cortex. Nine male Sprague-Dawley rats[250-300gm] received bilateral injections of ibotenic acid into the basal forebrain[A : +0.7mm, L : 2.3mm, D : 8.6mm] and additional five served as sham operated animals. Brains were removed at 8-14 days after lesioning and frozen coronal sections of 40 micrometer thickness were made. Immunohistochemical staining was performed against the somatostatin[SOM], neuropeptide Y[NPY], and vasoactive intestinal polypeptide[VIP]. No differences were observed in the number of the SOM-immunoreactive[SOM-ir] or NPY-ir neurons between the lesioned and the control groups. Density of the NPY-ir fibers also did not show any significant difference between the two groups. In contrast, the number of VIP-ir neurons in the frontal cortex was significantly reduced following the basal forebrain lesioning. These results suggest the functional relationship between the basal forebrain and the cortical VIP-ir neurons.

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.

Tumor angiogenesis has been found to have prognostic significance in many tumor types for predicting an increased risk of metastasis. We assessed tumor vascularity in 28 cases of borderline malignancy and 71 cases of carcinoma of the ovary which had been resected and diagnosed, using the highly specific endothelial cell marker CD34. The numbers of microvessels were counted in 200 magnification in three highly vascularised areas. The numbers of microvessels in carcinomas were higher than that in the borderline malignancy of serous and mucinous tumors. The number of microvessels of mucinous carcinomas was significantly higher than that of serous carcinomas. There were neither significant differences in the number of microvessels according to histological tumor types (p=0.075) nor significant differences in the number of microvessels according to FIGO stages (p=0.072). But in serous carcinomas, the number of microvessels was higher in the FIGO III-IV stage than in the FIGO I-II stage (p=0.017). This study showed higher neovascularization in malignant tumor than borderline malignancy, and in the advanced stage (FIGO III-IV) than less advanced stage (FIGO I-II) of serous carcinomas.

OBJECTIVE: The purpose of this study was to assess the role of HPV 16 and 18 in adenocarcinoma in situ(ACIS) of the uterine cervix. METHODS: Seventeen cases of primary cervical adenocarcinoma in situ were analyzed for HPV DNA by polymerase chain reaction. HPV 16 and 18 DNA extracted from formalin-fixed, paraffin-embedded histologic tissue sections by polymerase chain reaction. RESULTS: 35.3% and 23.5% of ACIS were positive for HPV 16 and HPV 18 DNA, respectively. From the normal tissue, 11.8% were positive for HPV 16. Human papillomavirus positive patients were younger than negative patients but statistically insignificant(mean age 42.1 vs 51.7 years). CONCLUSIONS: These results show that HPV type 16 and 18 were closely related to etiology of the ACIS of the uterine cervix.

The authors reviewed surgical materials from 20 patients with carcinoma of the extrahepatic biliary system, and a correlation between macroscopic appearance of the tumors with various clinical features and histopathologic findings was made. Microscopically, the tumors were classified into four types; Four (21%) patients had polypoid tumors, six (32%) had nodular growths, five (26%) were scirrhous constricting in type, and four (21%) had diffusely infiltrating type. Histologically all the differentiation in two cases. The degree of differentiation of the tumors was classified into 3 types: 11 (55%) patients were well differentiated, 3(15%) were moderately well and 6(30%) were poorly differentiated. All polypoid tumors were well differentiated and had low stage. No correlation in the degree of differentiation of the tumor with the stage was present. No correlation in clinical symptoms, duration of symptoms, laboratory findings with morphologic findings of the tumors was noted.

OBJECTIVE: To evaluate the significance of atypical squamous cells of undetermined significance(ASCUS) by following-up cervical cytologic smears or histologic finding. METHODS: Two hundred fifty three cases were diagnosed as ASCUS on cervical cytologic smears from January, 3, 1997 to september, 16, 1998 at cytopathology laboratory, College of Medicine, Keimyung Univemity. These cases were evaluated by cervical smears or subsequent biopsies. RESULTS: The results were as follows, On repeat cervical smears, inflammation was 19.7%, normal was 11,1% and HSIL was 1.6%. On histologic diagnosis, CIS was 13,4%, cervicitis was 12,6%, invasive cervical cancer was 4.0%, and severe dysplasia was 3.2%. CONCLUSION: A diagnosis of ASCUS on smears need careful follow-up.

Osteochondroma is one of the most common benign tumor. But, intraarticular occurrence is very rare. This tumor have been thought not a true neoplasm hut a developmental malformation or harnartoma. The authors experienced a case of intaarticular osteochondroma arising from inferior pole of pateUa, projecting into the infrapatellar fat pad. The tumor was excised surgically, and symptoms were relieved.

PURPOSE: The purpose of this study was to test effects of fatigue reduction program for women workers at a food production company. METHODS: A quasi-experimental design was conducted. Eighteen workers in vitamin E group, 16 workers in vitamin E and stretching group, and 18 workers in stretching only group participated. Participants were evaluated at baseline and 8 weeks. RESULTS: The results showed that stretching only group had a significant impact on reducing of fatigue level compared to those of a vitamin E group. CONCLUSION: Although vitamin E supplement has not shown decreasing fatigue level, the positive effect of stretching exercise may have high applicability to a workplace.
