As measurement of glomerular size in the assessment of several renal diseases becomes increasingly important, it has become necessary to devise rapid simple methods for the assessment of glomerular size and to have on hand reference ranges. A few reports on glomerular size have been published in Western literature, but their body builds are different from Koreans. In this study, 100 glomeruli(50 glomeruli each from the outer cortical and the juxtamedullary area) were measured in sections taken from 74 kidneys(ages 3 days~73 years) obtained from autopsy utilizing the semi-automatic image analyser. The percentage of glomerular sclerosis was measured based on its location. The sphere diameter, maximum diameter, area and sphere volume of non-sclerotic glomeruli were measured and evaluated with respect to age, sex and the location of the glomeruli. The results were as follows; 1) Mean glomerular dimensions including sphere and maximum diameter, area and sphere volume increased until 40 years of age, then reached a plateau. The percentage of sclerotic glomeruli then increased slowly with age but without statistical significance. 2) The glomerular dimensions and sclerosis showed no significant differences according to sex. 3) Juxtamedullary glomeruli were larger than the outer cortical ones which was statistically significant in age groups of 0~10, 11~20 and 41~50 years. The percentage of sclerotic glomeruli was generally greater in the outer cortex. 4) Differences in the values of glomerular dimensions between outer cortical and juxtamedullary area were similar in all age groups. 5) All parameters of measurement showed consistent and similar trends between the different groups. 6) The measurements of the largest 12 glomeruli out of randomly-selected 50 glomeruli gave similar results when compared with those of 50 glomeruli. It was evident from our results that glomerular size is influenced by age and glomerular location, but not by sex. The method of assessing glomerular size used in this study will not necessarily give the true, absolute value of size but it may be a simple, practical and useful method of comparing glomerular size in different groups of patients.

The rapid frozen section method is a means of intraoperative pathological diagnosis, first introduced by Welch in 1891 and developed as a diagnostic tool by Cullen, Wilson, MacCarty et al. This method serves useful purposes, such as determining the malignancy or benignancy of a suspected lesion, determining the adequacy of a biopsy of a suspected lesion, confirming the presence or absence of metatasis, and identifying small structures. But it bears many disadvantages, the most of which is the danger of incorrect diagnosis. We studied the indications, the limitations and the accuracy of the frozen section method and the materials studied was total cases of frozen section during recent 5 years. The ovarall accuracy of the frozen section diagnosis of 1,603 cases was 96.2% with 0.3% of false positive, 3.5% of false negative and 2.8% of incorrect histological diagnoses or grading errors the tissues submitted for frozen section were lymph node, breast, gastrointestinal tract and soft tissue in decreasing order of frequency. The false positive cases were four in number, while the false negative cases were 53, one third of which were the misdiagnoses of the presence of ganglion cells in Hirschsprung's disease.

Colonization of mammary cancers by melanocytes with heavy pigmentation of cancer cells by melanin can occur very rarely. It is not certain which mechanism operates to achieve this transfer. However, the melanocytes might inject melanin through their dendritic processes or alternatively, the cancer cells phagocytose the terminal parts of the dendritic processes with subsequent dispersal of the contained melanin contained melanin granules. We report a case of infiltrating ductal carcinoma of breast with melanocyte colonization and pigmentation in a 59-year old female.

Hyperkeratosis of the renal pelvis and ureter is a rare condition and is explained by the metaplastic change from transitional to cornified squamous epithelium. This lesion is frequently associated with, and perhaps caused by chronic urinary infection, but potentially premalignant, accompaning with carcinoma in about 10 to 20 per cent of the cases at the time of diagnosis. A case of hyperkeratosis of renal pelvis & ureter which was clinically suspected of carcinoma in a 49-year old woman with a long history of chronic pyelonephritis is presented with review of literature.

The purpose of this study was to investigate gender differences in behavioral characteristics and their awareness of obese school children. The results were as follows : 1. In comparison with eating habits and food preference, the girls had more irregular breakfast and were likely to have vegetables/fruits than the boys. 2. In characteristics related to exercise and activities, boys did more exercise than girls. Particularly, in lunch free time, boys participated in playing various active excercise with friends, but girls participated in more non-active behaviors(such as, chattering, reading, or playing jack-stones). 3. In comparison with their awareness related to obese persons, about a half of boys had positive opinions(e, grong, healthy.), but about only 20% of girls had positive opinions.

The purpose of this study were to define the degree of performance in health promoting lifestyle and to identify the variable related to performance inn health promoting lifestyle of adolescents. The subjects of this study were 469 adolescents in the 4 high schools. The sample data were collected using a purposive sampling method from July 1 to July 27. The collected data were analysed by using descriptive statistics, Pearson's correlation Coefficients, and stepwise multiple regression with SPSS PC+ program. The results of this research were as follows. First, The means of performance in the health promoting lifestyle of adolescents revealed total 2.478 ; harmonious relationships 3.045, regular diet 2.236, professional health management 1.322, sanitary life 2.910, self regulation 2.558, emotional support 2.696, healthy diet 2.048, rest and sleep 2.651, exercise and activity 2.491, self actualization 2.466, diet control 2.408. The factor with the highest degree of performance was the harmonious relationships, whereas the one with the lowest degrees was the professional health management. Second, the relationship between the degree of performance in health promoting lifestyle and its related variable were as follows. (1) Performance in the health promoting lifestyle was significantly correlated with self esteem, self efficacy, health conception, perceived health status, mother's health promoting lifestyle, mother's health conception. (2) The most important factor that affects performance in the health promoting lifestyle of adolescents was self esteem. The combination of self esteem, health conception, mother's health promoting lifestyle, self efficacy, perceived health status accounted for 45.2% of the variance in health promoting lifestyle of adolescents.
