About 6,950 feather mites were isolated from filed collections and examination of bird study skins at the zoological specimen room of Kon-Kuk University in Seoul. Among them, 3 species of Kramerellidae, Dermonoton longiventer (Megnin & Trouessart, 1884), Kramerella bubonis (Lonnfors, 1937), Neopetitota bubonis Atyeo & Philips, 1984, and 1 species of Pterolichidae, Epopolichus atelus Gaud, 1981, were newly recorded from Korea. They were redescribed with their new hosts.

The development of immuohistochemistry and the application of electron microscopy have revolutionized our understanding of the pathopysiology of pituitart adenoma. The clinical value of functional characterization of pituitary adenoma has been realized. Immunohistochemical stains using polyclonal antibodies to six pituitary hormones (GH, PRL, ACTH, TSH, FSH & LH) were performed to classify the pituitary adenoma and to investigate the relationship between the results of the immunohistochemical study and pared to the serum hormone level. The results are summarized as follows: The Most common clinical type of pituitary adenoma was prolactinoma and the second was nonfunctioning adenoma. However, the most common immunohistological type of pituitary adenoma was null cell adenoma, the second one, lactotrope adenoma and the third one, mixed sommatotrope & lactotrope adenoma. In the clinically nonfunctioning adenoma cases, null cell adenoma were present in 75%; gonadotrope adenoma and corticotrope adenoma were present in 25%, while the serum prolactin level was increased in ten of the twenty cases(50%) of the null cell adenoma. When the serum prolactin level was increased above the 150ng/ml, the tumor cells gave positive reactions in 95.2% of cases immunohistochemically. But in the cases of GH, FSH & LH, the tumor cells gave positive reactions in 100%, 75%, and 66.7%, respectively. In the case of increased serum prolactin level, more than 50% and 30% proportion of tumor cells showed positive reactions in the micro- and macroadenoma, respectively.

Objective To observe the clinical effects of chemotherapy with intraperitoneal hyper-thermal perfusion for malignant ascites. Methods 40 patients with malignant ascites were randomly divided into two groups. In the treated group, 21 patients underwent intraperitoneal hyperthermal perfusion and local thermotherapy. 19 patients in the control group received commonly intraperitoneal perfusion. Results The CR, PR patients were 6,10 and 0,7 in the treated group and control group, respectively. The efficacy rate in the treated group was significantly higher than that in the control group. 2 patients oc-cured bellyache in the treated group and 1 patient in the control group, there was no statistically significant difference between the two groups. Conclusion Chemotherapy with intraperitoneal hyperthermal perfusion can significantly improve the therapeutic effects for malignant ascites, and has no more side effects.

We report a case of occult primary spontaneous pneumothorax in a 30 years-old woman. She developed symptoms and signs that were suggestive of pneumothorax. However, chest radiograph failed to reveal pneumothorax. Therefore, we proceeded with computed tomography (CT) thorax which revealed significantly moderate right pneumothorax. The diagnostic approach and the management of this case are discussed.

Optic nerve sheath meningioma arises from the arachnoid cap cell of optic nerve sheath and comprises most of primary orbital meningioma. We experienced a rare case of optic nerve sheath meningioma originating in the left orbit. A 44-year-old woman had suffered from visual disturbance in the left eye for 3 years and had only light perceptibility for the recent 6 months. The right eye was normal. Brain CT scan and MRI revealed a 2x0.8 cm sized fusiform solid mass in the left retrobulbar area. Under the impression of optic nerve tumor. excision of the mass including a small segment of the optic nerve was performed. The tumor was a yellowish firm, relatively well demarcated mass that encircled the optic nerve without infiltrating it. Microscopically it was a typical meningioma, meningothelial type. The recovery of visual acuity was impossible due to resection of optic nerve but there was no evidence of recurrence for u months.

There is a great variety of abdominal calcifictions of varying etiology. Among them, calcification in gastriccarcinoma is rare. To the best of our knowledge, there has been no previous report of calcifying mucinousadenocarcinoma of the stomach in Korea. In the present communication, we report two cases of this rare tumor. Thefirst case was 27 years old female who had anorexia and palpable mass in the epigastrium. By palpation, a firmnon-tender large mass ws felt in the epigastrium. A plain abdominal film showed numerous pnuctate calcificationsin the left upper quadrant. Film from an upper G-I series demonstrated findings of advanced gastric carcinoma withmultiple punctate calcifications involving the antrum and body. Gastroscopic biopsy proved the lesion to bemucinous adenocarcioma(signet ring cell type). The second case was 38 years old female who compained of nausea,vomiting and weight loss. On physical examination, she appeared normal. Routine laboratory tests were withinnormal limits. A plain abdominal film revealed stippled calcifications in the left upper quadrant medial to thesplenic shadow. The film from an upper G-I series showed a mass in the fundus and upper body of stomach withmultiple stippled calcifications along the lesser curvature. Subtotal gastrectomy was perfomred and the pathologicfindings was calcifying mucinous adenocarcinoma(signet ring cell type).
