The nucleolus of human cell is a morphologically well recognizable nuclear organelle and the argyrophilic NORs (AgNORs) are nucleic acid-argyrophilic nonhistone protein complex in the nucleoli and the silver staining allows their identification and enumeration at the light microscopic level. The AgNOR counts are in parallel with mitotic activity and vary in different phase of cell cycle. It has been reported that human cells have one AgNOR during interphase and S-phase. However, the correlation between the number of AgNORs and S-phase markers is still controversial and they have never been studied simultaneously. In this study, AgNOR and PCNA were stained simultaneously to find out the relationship of AgNOR counts with cell cycle (S-phase) in human palatine tonsil, gastric carcinoma, liver and brain tissues. S-phase cells (PCNA-positive) were found predominantly in lymphoid follicles in palatine tonsil but gastric carcinoma showed diffuse immunoreactivity for PCNA. The AgNOR counts varied according to the type and locus of tissue. More than one AgNOR were identified in S-phase cells and some of hepatocytes and neurons in the brain which were not in S-phase contained two or more AgNORs. The above results suggest that the number of AgNOR is a characteristic feature of each type of cells and can be more than one even in S-phase.

Nodular pseudosarcornatous fasciitis is a benign, fibrohlastic proliferative disease. This case report is one of a hard nodule which a 35-year-old male suddenly discovered on his right forearm 10 days prior to being aeen. The nodule showed characteristic histological findings of nodular pseudosarcomatous fasciitis.

Gastric lesion in familial polyposis coli is commonly presented with fundic gland hyperplastic polyps, but duodenal and gastric adenomas together with their carcinomatous transformation have been rarely described in familial polyposis coli mostly by case reports. We present three cases of gastric adenomas in familial polyposis coli with one in synchronous development of gastric adenocarcinoma in Korea. All three cases had the family history related to familial polyosis coli and received proctocolectomy because of synchronous development of colonic adenocarcinoma. One patient developed gastric polyposis and adenocarcinoma 8 years after colectomy, and the remaining two presented with multiple polyps either in the stomach or duodenum synchronously at the time of the diagnosis of familial polyposis coli with colonic adenocarcinoma. None disclosed any evidence of Gardner's syndrome. We conclude that association of gastric adenomas in familial oplyposis coli is not uncommon and gastric adenoma-carcinoma sequence is an another important participating mechanism to understand the histogenesis of gastric carcinoma in Korea.

Generalized lipodyst,rophy is characterized by generalized loss of body fat, and is asociated vith metabolic ahnormalities, including insulin resistance, hyperglycemia., and hypertriglyceridemia. like acanthosis nigricans, generalized lipodystrophy is a cutaneous marker of insulin re.istant diabetes. We report. herein a twenty year old female witti both classic generalized lipodystripin and acanthosis nigricans, in association with insulin resistant diabetes.

A Statistical analysis was made on 275 cases of urinary calculi During the period from Jan.. 1963 to Aug. 1972, on the Department of Urology of Han-il Hospital and the results were obtained as following; 1. The incidence of urinary calculi was 3.09 % of out-patients. 2. The age of the patients ranged from 20 to 30 years in approximately 70 percent. 3. A seasonal occurrence was highest during summer on 31 percent. 4. The locational distribution of urinary calculi was 71.6 percent in ureter, 18.2 percent in kidney, 7.5 percent in bladder, 2. 7 percent in urethra. 5. The locational distribution of ureter calculi was 66 percent in lower, 22 percent in middle and 12 percent in upper portion. 6. In a number of urinary calculi, 89. 8 percent was single and 5.8 percent was double and 4.4 % was more than 2. 7. The ureterolithotomy was performed on 74 of 197cases requiring surgical intervention. Cystoscopic manipulation (Spontaneous Expelled) and conservative treatment were 120 cases of 197 cases. Other manner on 3 cases. 8. The results of qualitative analysis of 240 urinary calculi showed cal. Phosphate + oxalate in 53.7 percent, Cal phosphate in 13.7 percent, Calcium phosphate + ammonate in 7.5 percent, Ca phosphate +carbonate in 7.1 percent, Ca carbonate in 5.O percent. Ca oxalate in' 4.2 percent. etc.
