1.A Ultramicroscopic Study Cryptococcus Neoformans Derived from Pigeon Drops.
Korean Journal of Dermatology 1977;15(3):297-303
The morphologic differences hetween a mucoid and pasty type of Cryptococcus neoformans derived from pigeon drops were investigated using an eIectron microscope. The following results were obtained: No essential differences in ultramicroscopic structures were noted hetween the mucoid and pasty type of C. neoformans, but the capsule is thicker in the mucoid type than the pasty one and the intracytoplasmic structures were seen more clearly in the mucoid type. These differences seem to he related to chemical components and the difficulty of penetration of fixing solution through thick capsules. There were no differences between C. neoformans derived from pigeon drops and those from pathogenic strains which were reported by others. Therefore, C. neoformans derived form pigeon drops can infect humans.

In the beginning of anesthetic training, one of the clinical practices that anesthetists have to learn is manually controlled ventilator techniques. The popularity of manually controlled ventilatory techniques has been gradually decreased with increased use for anesthetic ventilators. However it is important and basic for the anesthetists to master manually controlled ventilator techniques skillfully. Recently, we analyzed the arterial blood gas in 30 cases before and during general anesthesia, and studied the effects of the manually controlled ventilation on the pulmonary gas exchange. The results were as follow; 1) Mean value of PaCO₂ during the manually controlled ventilation, 29.9±2.0 mmHg was decreased statistically comparing with that of PaCO₂ before the anesthesia, 39.8±2.8 mmHg. 2) Mean values of pH and HCO₃⁻ during the manually controlled ventilation were 7.48±0.03, 22.2±2.4 mEq/1, respectively and values before the anesthesia were 7.41±0.02, 25.2±1.8 mEq/1, respectively. 3) Mean value of PaO₂ and O₂ saturation during the manually controlled ventilation were 270.0±28.8 mmHg, 99.6±0.2%, respectively and values before the anesthesia were 92.5±4.0 mmHg, 96.9±1.0%, respectively. These results indicates that manually controlled ventilation at our department of anesthesiology produced mild hyperventilatory state. However these were no significant changes in cerebral blood flow and other biochemical parameters.

It is well known the CT is very useful in the evaluation of gallbladder carcinoma. We have studied 19 cases of gallbladder carcinoma with whole body scanner from May 1980 to Aug. 1983. 1. The sex distribution were 11 males and 8 females with over 40 years of age. 2. The computed tomographic classificications of the cases were 7 of intraluminal fungating mass(single 5 and multiple 2), 5 of mass filling the gallbladder, 5 of irregular thickened GB and 2 of mixed type, irregular thickned wall and intraluminal fungating mass. 3. CT demonstrated metastasis of other organ, 8 cases of the liver, 5 cases of the extrahepatic bile duct, 3 cases of peritoneum, 2 cases of duodenum, 1 case of the stomach, 1 case of the pancreas, and 15 cases of lymph nodes. 4. Associated diseases were6 cases of gall stone, 2 cases of clonorchiasis, 1 case of pancreatic pseudocyst, and 1 case of renal cyst.

6.Adult Wilms' Tumor: Monomorphous Epithelial, Tubular, Variant.
Korean Journal of Pathology 1985;19(4):473-477
Adult Wilms' tumor, unlike that of childhood, is a rare disease. Microscopically, the tumor is fundamentally characterized by triplastic embryonal renal tumor composed of variable amounts of metanephric blastema and its epithelial and stromal derivatives but rarely a small group of tumors composed virtually entirely of differentiated epithelial derivatives, the abundance of tubular structures. These monomorphous epithelial type of Wilms' tumor tended to have an early onset and benign course. Grossly, classic Wilms' tumor is a solid tumor, but very rarely shows cystic change and may lead to misinterpretation as a polycystic kidney or multicystic nephroma. Here, we reports a case of primary renal tumor, grossly very similar to a multicystic kidney but histologically represent a tubular monomorphous epithelial variant of Wilms' tumor occured in 63 year old male adult.

Korean Journal of Dermatology 1974;12(4):301-304
A case of incontinentia pigmenti without any developmental defect has been presented. And literatures have been reviewed. The patient was a 20 year old female and had been affected with numerous dark brownish linear streaks of pigmentation on the entirebody. No familiar traits were noted. Diagnosis was confirmed by characteristic clinical picture, laboratory and histopathologic findings.

A Case of prurigo nodularis in 47-year-old female was presented with brief review of literatures. This is one of relatively rare dermatoses and still has many disputes in etiology and classification. Multiple erythematous brownish hyperkeratotic lichenified nodules were scattered on the back and extremities associated with intolerable itching trouble. Histopathologically, severe hyperkeratosis with focal neutrophile infiltration and pseudoapitheliomatous hyperplasia of acanthotic lesion in the epidermis is presented. Diagnosis was confirmed by characteristic clinical pictures and histopathological features. Treatment with corticosteroids, sediatives and tranquilizers revealed of favorable results.

9.Hyperplasia, Metaplasia, and Dysplasia of the Gallbladder Correlation to Gallbladder Adenocarcinoma.
Korean Journal of Pathology 1997;31(6):527-537
The correlation of metaplasia to dysplasia and carcinoma in the gallbladder has attracted the attention of many investigators. We mapped and examined a total of 263 cholecystectomized gallbladders to analyze the mucosal changes in the carcinogenesis of the gallbladder. Stones were present in 59.7%, hyperplasia in 28.5%, metaplasia in 55.5% (gastric 37.6%, intestinal 17.9%), dysplasia in 17.1% (low grade 9.1%, high grade 8%) and carcinoma in 7.6%. Metaplasia was more frequently identified in the stone-positive group (62.4%) than in the stone-negative group (45.3%) (P<0.05). Especially, the incidence of intestinal metaplasia was significantly higher in the stone-positive group. Dysplasia and carcinoma were more frequent in the metaplasia-positive group (dysplasia 26.7%, carcinoma 11%) than in the metaplasia-negative group (dysplasia 5.1%, carcinoma 3.4%) (P<0.05). Their incidences were significantly higher in the intestinal metaplasia than in the gastric metaplasia. Forty four percent of the dysplasia-positive cases were associated with carcinoma in the adjacent mucosa but carcinoma was absent in the dysplasia-negative cases. Hyperplasia did not reveal any significant correlation with metaplasia, dysplasia and carcinoma. These results suggest that gallstone is causally related to the metaplasia in the gallbladder and the metaplasia-dysplasia- carcinoma sequence exists in the gallbladder.

10.Pathologic Analysis of Gallbladder Cancer by the Stage and Intestinal Metaplasia with the Diagnostic Significance of CEA and p53.
Korean Journal of Pathology 1997;31(7):599-607
Twenty cases of gallbladder cancers were examined using 5 mm stepwise tissue sections. We analyzed the clinicopathologic findings of the early (stage 1, II) and advanced carcinoma (stage III, IV, V) and those of carcinoma with or without metaplasia in the tumor. We also performed CEA and p53 immunohistochemical staining and compared their findings with those of normal mucosa and preneoplastic lesions. The results were as follow: 1) All of the early carcinomas (n=5) were incidentally diagnosed after the resection for the gallstone. They were compared to advanced carcinoma (n=15) in the absence of the lymphatic or angioinvasion, recurrence, metastasis and death. 2) Metaplastic and non-metaplastic carcinoma did not reveal any difference of the clinicopathologic findings except age distribution. 3) CEA and p53 were positive in preneoplastic and malignant lesions. The extent of staining was related to the degree of the atypia. From the above results, an early detection of gallbladder cancer is very important for the prognosis of the patients. Since preoperative diagnosis is difficult, thorough pathologic examination of routinely resected gallbladder is necessary for the early diagnosis. CEA and p53 immunohistochemical staining may be helpful in the differential diagnosis of non-neoplastic and neoplastic lesion of the gallbladder.
