This study was performed to fine out the possible causes of primary infertility in female and to provide some diagnostic and therapeutic modalities. A total of 104 cases of endometrium in primary infertility was obtained from the pathology files of Chosun University Hospital and Kwang-ju Christian Hospital during the period of 5 years and 10 months from January, 1984 to October, 1989. The endometrial biopsies were taken on the first of menstruation and classified according to Noyes, Hertig and Rock's criteria. Histologic findings which were compatible with their normal menstrual cycle (premenstrual of late secretory phase and bleeding phase) were noted in 52 cases (50%). Abnormal 52 cases (50%) revealed deficient secretory phase in 36 case (34.6%), proliferative phase in 5 cases (4.8%), irregular proliferation and chronic nonspecific endometritis in 4 cases (3.8%), respectively, endometrial hyperplasia in 3 cases (2.9%), tuberculous endometritis in 2 cases (1.9%), and asynchronous cycle in 1 case (1%). Among the case of dissociated delay was 21 cases (20.2%) and coordinated delay was 15 cases (14.4%). Therefore, deficient secretory phase with dissociate delay was most common abnormal endometrial finding in cases of female primary infertility. The peak age distribution of the female primary infertility in this study revealed 73 cases (63.8%) in patients between the age of 25 and 29. This finding indicated that there was no significant relationship between the age distributions and the endometrial histopathologic findings.

Tracheal tumors are uncommon comprising less than 0.1% of all malignancies. Metastatic tracheal tumors, especially form the extrathoracic sites, are exceedingly rare. Ovarian cancer tends to metastasize to the serous cavities and the lymph nodes. One large autopsy study reported tracheal involvement in 1% of patients who had died from ovarian cancer. Other studies have not mentioned tracheal involvement at all. Since the main symptoms of cough, hemoptysis, or wheezing are nonspecific, patients may be initially treated for other conditions including asthma or bronchitis. Here we describe a metastatic tracheal tumor from an overain carcinoma that was initally treated for bronchial asthma.

Liposarcoma of the male breast is rare. In English literature, nearly 90 tumors of this type can be found, but the majority of citation is female without detail descriptions of gross or microscopic features. Recently, we experienced a case with pleomorphic liposarcoma of the breast. This 62-year-old male patient presented with tumorous mass of right breast for 3 months ago. He underwent radical mastectomy under the impression of breast cancer. Received specimen was a breast and attached nodular bulging mass. The serial section reveal a relatively defined nodular mass consists of yellowish and glistened bulging tumorous lesion, measuring 5x4.5x5cm. Microscopically, there were multiple pleomorphic giant cells composed of plump esoinophilic or microvesiculated cytoplasm and bizarre nuclei with prominent nucleoli. These cells were positive staining for oil-red O. Ultrastructurally, variable sized numerous fatty vacuoles in the cytoplasm were seen.

This study describes an evaluation of the sonographic, cholangiographic, pathological, and immunological findings, and the protective effect shown by rats reinfected with Clonorchis sinensis. Eight experimental rat groups were, namely, a normal control, a primary infection control, a reinfection I (reinfection 7 week after treatment following 3-week infection), a reinfection II (reinfection 2 week after treatment following 8-week infection), a reinfection III (exploration of the intrahepatic bile ducts 1 week after reinfection 4 week after treatment following 4-week infection), a superinfection, a secondary infection control, and an infection following immunization group. Sonographic and cholangiographic findings showed moderate or marked dilatation of the bile duct confluence in the primary infection control, reinfection II, and secondary infection control groups. Juvenile worms survived in the intrahepatic bile ducts 1 week after reinfection following treatment in the reinfection III group. It was concluded that reinfecting juvenile worms found during the first week following reinfection failed to survive or grow further. Anatomical, pathophysiological, or immunological changes may induce protection from reinfection in rats.

Hemangiopericycic maningioma is clinically and pathologically similar to peripheral Hemangiopericytoma and now tends to be terned as hemangiopericytoma of central nervous system. The authors studied 3 cases of hemangiopericytic meningioma obtained from 3 patients, 1 case of meningotheliomatous meningioma, angioblastic meningioma and transitional meningioma, and 2 cases of peripheral hemangiopericytoma, which had operated from November 1988 to May 1989 at the department of neurosurgery, Pusan Inje University Hospital. The authors analysed and compared the immunohistochemical finding and light microscopic apearance. The results obtained were summarized as follows; 1) Classic maningioma (meningotheliomatous meningioma, transitional meningioma and angioblastic meningioma) shows reactivity to both EMA and vimentin. 2) Hemangiopercicytic meningioma and peripheral hemangiopericytoma are reactive only to vimentin, so the two tumors are suggested as same type of tumor. 3) One of 3 cases of hemangiopericytic meningioma shows whorling and interlacing bundles of spindle cells, the peculiar light microscopic features of transitional meningioma, suggesting transitional or mixed form of hemangiopericytic meningioma and transitional meningioma.

Auricular arterio-venous malformation(AVM) is relatively rare and few have been reported in the literature. Two cases, presented here showed pulsating lesions of anterior and posterior auricular or even retroauricular mastoid area. They caused irregular macro and prominent ear compared with the opposite normal ear. After embolization of feeding arteries to the arteriovenous malformations, skin and subcutaneous masses were completely removed and grafted with full thickness skin: one was removed one stage and the other underwent a two stage operations. There were no evidence of recurrence for more than 2 years follow up and esthetic results were promising.

PURPOSE: The pvrpose of this study was to evaluate the accuracy of radioactivity quantitation in Tc-99m SPECT by using combined scatter and attenuation correction. MATERIALS AND METHODS: A cylindrical phantom which simulates tumors (T) and normal tissue (B) was filled with varying activity ratios of Tc-99m. We acquired emission scans of the phantom using a three-headed SPECT system (Trionix, Inc.) witb two energy windows (photopeak window: 126 154 keV and scatter window: 101 123 keV). We performed the scatter correction with dual-energy window subtraction method (k=0.4) and Chang attenuation correction. Three sets of SPECT images were reconstructed using combined scatter and attenuation correction (SC+AC', attenuation correction (AC) and without any correction (NONE). We compared T/B ratio, irnage contrast [(T-B)/(T+B)) and absolute radioactivity with true values. RESULTS: SC+AC images had the highest mean values of T/B ratios. Image contrast was 0.92 in SC+AC, which was close to the true value of 1, and higher than AC (0.77) or NONE (0.80). Errors of true activity by SPECT images ranged from 1 to 11% for SC+AC, 22-47% for AC, and 2 16% for NONE in a phantom which was located 2.4cm from the phantom surface. In a phantom located 10,0cm from the surface, SC+AC underestimated by ?4%, NON.E 40%. However, AC overestimated by 10%. CONCLUSION: We conclude that accurate SPECT activity quantitation of Tc-99m distribution can be achieved by dual window scatter correc.tion combined with attenuation correction.

The objective of this study was to investigate the relationship between insomnia severity, depression, anxiety, and anxiety sensitivity and to find out the explanatory variables that account for the insomnia severity among depression, anxiety, and anxiety sensitivity in general population. 95 mentally healthy volunteers who visit health promotion center of Kangbuk Samsung hospital for their regular medical examination were requested to complete Athens Insomnia Scale, Beck Depression Inventory, State-Trait Anxiety Inventory, and Anxiety Sensitivity Index. Association between total scores of Athens Insomnia scale and other variables (total scores of Beck Depression Inventory excluded item 16, total scores of State Anxiety, total scores of Trait Anxiety, and total scores of Anxiety Sensitivity Scale) was assessed individually with partial correlations adjusted by age and then together using multiple regression analysis. The total scores of Athens Insomnia Scale were significantly associated with total scores of Beck Depression Inventory excluded item 16(r = 0.541, p<0.001), total scores of Trait Anxiety(r = 0.642, p<0.001), total scores of State Anxiety(r = 0.267, p<0.05), and total scores of Anxiety Sensitivity Index(r = 0.312, p<0.01). Total scores of trait anxiety showed the highest correlation with the total scores of Athens Insomnia Scale and was the significant predictor to total scores of Athens Insomnia Scale among the other predictor variables (p<0.001). These results show that insomnia severity is positively correlated with depression, anxiety, and anxiety sensitivity. The correlation was strongest with trait anxiety. In addition, our results suggest that trait anxiety is associated with insomnia severity in general populations.
