Nucleolar organizer regions (NORs) are loops of DNA which occur in the nucleoli of cells which possess ribosomal RNA genes. The numbers and areas of NORs have been thought to be related to cellular activities. We aimed to investigate the direct relationship between the parameters of AgNORs and cellular proliferative activity using immunohistochemical method with the monoclonal antibody Ki-67, which demonstrates proliferating nuclei. The sequential technique for the simultaneous Ki-67 immunostaining and NOR staining was applied to the same slides of a series of non-Hodgkin's lymphomas (NHL) of the low, intermediate, and high grade type. The number of AgNOR per cell was counted and mean NOR percentage nuclear area (NPNA) was measured by morphometry in both the Ki-67 positive and Ki-67 negative nuclei. The increased immunoreactivity for Ki-67 was found in the high grade than in the low grade non-Hodgkin's lymphoma. This was reflected in the two areas of the palatine tonsils and lymph nodes, the positive cell counts being higher in the follicle center nuclei than in those in the interfollicular compartment. In general the numbers and NPNA of AgNORs were higher in the Ki-67 positive nuclei than in those lacking the antigen in malignant lymphomas as well as in control. The AgNORs numbers and NPNA in controls were the highest in the Ki-67 positive cells in the follicular area and the lowest in the Ki-67 negative cells in the perifollicular area. In malignant lymphomas the numbers and NPNA of AgNORs tended to increase in proportion to their grade in both the Ki-67 positive and negative cells. The numbers of AgNORs of the high grade and the NPNA of the intermediate and the high grade were significantly higher in Ki-67 positive cells than in Ki-67 negative ones. With this double staining method it was now possible to confirm that numbers and NPNA of AgNORs were directly related to the cellular proliferative activity. In maligant lymphoma, among the several parameters of the AgNORs, NPNA in Ki-67 positive cells is proposed to be the most useful marker in determining the prognosis of the patient.

Matrix metalloproteinases (MMPs) and their inhibitors (tissue inhibitors of matrix metalloproteinases, TIMPs) play essential roles in the remodelling of the extracellular matrix. The balance between MMPs and TIMPs is altered in neoplasia, contributing to the invasive and metastatic properties of malignant tumors. Although MMP and TIMP are believed to play an important role in invasion and metastasis in malignant solid tumors, little is known about their involvement in malignant lymphoma. Immunohistochemical stains for MMP-1, MMP-2, MMP-9, TIMP-1 and TIMP-2 were performed using 56 paraffin blocks of the malignant lymphoma and the results were analyzed by using the tumor grade by Working Formulation. The expression of MMP-9 was noted in 45.5% of low grade, 86.1% of intermediate grade, and 100% of high grade malignant lymphoma. The incidence of MMP-9 expression in tumor cells was positively correlated with the grade of the malignant lymphoma (P<0.025). In nodal lymphomas, the incidence of the MMP-9 expression of the tumor cells was higher in malignant lymphoma with extracapsular invasion than those without extracapsular invasion (P=0.008). The incidence of TIMP-1 expression in the tumor cells and fibroblasts was positively correlated with the grade of the malignant lymphoma (P<0.025). In nodal lymphoma, the incidence of the TIMP-1 expression of the tumor cells was higher in malignant lymphoma with extracapsular invasion than those without extracapsular invasion (P=0.009). The incidences of the MMP-1, MMP-2, and TIMP-2 expression in malignant lymphoma were neither increased in the malignant lymphoma with extracapsular tumor invasion nor correlated with the grade by working formulation. There was no significant difference in the expression rate of MMP-1, MMP-2, MMP-9, TIMP-1, and TIMP-2 in nodal- and extra-nodal malignant lymphoma. The above results suggest that the expressions of MMP-9 and TIMP-1 are positively correlated with the grade and the presence of extranodal tumor invasion in malignant lymphomas.

The 4,725 cattle in the enzootic region, 6 counties of southern Korea, were surveyed for besnoitiosis epidemiologically by examining the scleral conjunctiva for the cysts and the following results were obtained. The survey showed that 285 cattle, representing 6 per cent of a total of 4,725 cattle examined had S.C. cysts. Only 49 (14 per cent) of them showed clinical sclerodermatitis and the ratio between clinical and inapparent cases was 1:5.8. On age distribution of the S.C. positive cases the highest incidence(10-12 per cent) was seen in amimals that were from 5 to 8 years of age, but clinically apparent cases occurred much more in younger age of animal. In local incidence of S.C. cysts positive cases the prevalence was higher in the secluded districts such as Koheung and Sancheoung counties(9 per cent).

OBJECTIVES: The aim of this study was to examine the relationship between personality of parent and offspring, and offspring's psychological adaptation. METHODS: We examined temperament and character of 65 parents and their offspring (measured using the Junior Temperament and Character Inventory and Temperament and Character Inventory) and offspring's internalizing (anxiety, depression) and externalizing (delinquency, hyperactivity) problems. RESULTS: The internalizing problems of offspring were positively associated with harm avoidance (HA) of offspring and parent, and negatively associated with self-directedness (SD) of offspring and parent. The externalizing problems of offspring were positively associated with novelty seeking of offspring, and were predicted by SD of parent. The interaction between parent's HA and offspring's HA predicted higher levels of anxiety of offspring. CONCLUSION: The association between the offspring's personality and internalizing and externalizing problems can depend on the personality of the parent.

PaO2 and PaCO2 values were studied in 8 surgical patients with a modified Flagg can system anesthesia. Arterial blood gases were analyzed with a Radiometer before every induction, after the first 30 minutes of anesthesia and in the immediate post-anesthetic period. The following results were obtained: 1) The values of PaO2 and PaCO2 in all cases during anesthesia did not show any remarkable change. 2) In cases, with no necessity of muscle relaxation or assisted and controled respiration, especially in children, the modified Flagg can system anesthesia seemed to be safe, simple and economical.

In the case of IIc type of early gastric cancer occuring from the area of ulcer sear, endoscopic differentiation between it and beoign ulcer scar is occasionally very difficult, due to the absence of characteristic malignant features. The presence of the irregular granular mucosal changes on the area of ulcer scar may be very helpful in the differential diagnosis between early gastric cancer and benign ulcer sear. And underetanding of the malignant cycle of early gaetric cancer is very important for the diagnosis of the depressed forms of early gastric cancer, We experienced and report a cases of IIc type of early gastric cancer diagnosed before operation by the endoscopic finding of irregular granular mucoeal changes on the area of ulcer scar and showing part of malignant cycle.
