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.

Eosinophilic leukemia is a rare variant of granulocytic leukemia. It has distinct clinical features to involve central nervous system, heart, lung and skin more frequently than other leukemia and laboratory findings to reveal persistent eosinophilia with immature tendency, leukocytosis, anernia, thrombocytopenia and usually negative philadelphia chromosome in cytogenetic study. We describe a 33 year-old male patient who has suffered from generalizid weakness exertional dyspnea and has had well defined, hen eggs ized, oval shaped and non-in-durated ulcerative lesions on the right thigh since about 4 months prior to admission. The laboratory findings were persistent leukocytosis, eosinophilia and immature tendency in peripheral blood, nearly 100% cellularity and eosinophilic tendency (70%) in bone marrow aspiration and biopsy, and negative philadelphia chromosome in cytogenetic study. A biopsy specimen from ulcer margin showed relatively intact epidermis and heavy cellular infiltration composed of eosinophilic cytoplasm, dark and indented nucleus in entire dermis. Normal appearing skin also revealed same cellular infiltration in dermis with perivascular and periadnexal pattern.

Quaternium-15 (Dowicil 200) which is a water-soluble antimicrobial agent and a formaldehyde releaser is widely being used as a preservative in cosmetics and medicaments these days. However, there are scanty reports about it in the Korean literature. Recently, we have experienced two cases of Quaternium-15 contact dermatitis probably related with their cosmetics and topical medicament, respectively. We report our cases with the patch test results.

To investigate the immunohistochemical expression of mutated p53 protein and bcl-2 protein in the cutaneous melanocytic lesion, 15 cases of compound nevus, 10 cases of congenital melanocytic nevus, 15 cases of primary malignant melanoma(4 cases less than 1.5 mm thick and 11 cases more than 1.5 mm thick), and 10 cases of metastatic malignant melanoma(7 cases in lymph node and 3 cases in soft tissue) were examined. All cases of compound nevi and of congenital melanocytic nevi showed no immunoreactivity for p53 protein. p53 protein overexpression was observed in 75%(3/4) wth primary malignant melanoma less than 1.5 mm thick, 81%(9/11) with primary malignant melanoma more than 1.5 mm thick, and 100%(10/10) with metastatic malignant melanoma. The difference in p53 protein overexpression was statistically significant between benign nevi and malignant melanoma(p<0.01). Bcl-2 protein expression was observed in 73%(11/15) with compound nevus, 70%(7/10) with congenital melanocytic nevus, 75% (3/4) in primary malignant melanoma less than 1.5 mm thick, 54%(6/11) with primary malignant melanoma more than 1.5 mm thick, and 40%(4/10) with metastatic malignant melanoma. These findings suggested that mutation of p53 gene may be an important mechanism in the development of malignant melanoma. Although bcl-2 protein was expressed in cutaneous melanocytic lesion, no correlation was found between p53 protein and bcl-2 protein expression in malignant melanoma.

The purpose of this study is to evaluate the change of mucosal immunity in gastric diseases. A quantative analysis of IgA and secretory component(SC) in gastric diseases by immunohistochemical method was performed in 110 specimens. The results are as follows: 1) In normal gastric mucosa, all of 10 cases revealed a negative reaction to antihuman SC but 4 cases were positive for IgA. 2) In chronic superficial gastritis and chronic atrophic gastritis with intestinal metaplasia, the metaplastic cells except for the goblet cells were positive for both IgA and SC. 3) The dysplastic cells were also positive for both IgA and SC, and the regenerating cells in ulcer as well. 4) All of the well differentiated or moderately well differentiated adenocarcinomas showed positive reactions to antihuman IgA and antihuman SC, and the intensity appeared to be stronger in the former. However, among 10 cases of poorly differentiated adenocarcinoma SC was not demonstrated in 5 cases, and no IgA was present in one case. In 10 cases of signet ring cell carcinoma, 6 cases revealed a negative reaction to antihuman IgA and 6 cases to antihuman SC. The above results suggest that the secretory immunity is not essential in normal gastric mucosa. The intestinal metaplasia in chronic gastritis is considered as an adaptive response to chronic inflammation. The degree of differentiation in adenocarcinoma may be related to the mucosal immunity.

Congenital cystic adenomatoid malformation of the lung is a rare form of congenital cystic disease of the lung and associated with developmental arrest of bronchioles in embryonic life. We report 3 cases of congenital cystic adenomatoid malformation which are classified as type I, II and III according to the morphological classification by Stocker et al. The first case was a 6-year-old female with a mass in the lower lobe of the right lung. The mass was composed of several cysts which were filled with inflammatory exudate and lined by ciliated pseudostratified columnar epithelium (type I + II). The second case was a 4-year-old female with a mass in the middle lobe of the right lung. It was composed of numerous small cysts which were uniform sized and contained inflammatory exudate. These were lined by ciliated columnar and pseudostratified columnar epithelium (type II). The third case was a stillborn female at 27 weeks of gestation. There was generalized edema and severe ascites. The left lower lobe consisted of an ill-defined solid area and small cysts. The solid lesion was composed of bronchiole-sized cysts lined by non-ciliated cuboidal epithelium (type II + III).

We present a case of pemphigus vulgaris developed during pregnancy. The clinical features of this patient were similar to those of hetpes gestationis. By immunofluorescence studies we found that the patient's serum contained autoantibodies to intercellular substance of epidermis. Direct immunofluorescence microscopy of a perilesional skin also demontrated immunoglobulin deposition in the intercellular areas. Additionally we did in vitro C3 staining for further confirmation of the diagnosis but it was negative in basement membrane zone. This patient was initially treated with corticosteroid and azathioprine. Several months later gold compound was given instead of azathioprine and corticosteroid with good therapeutic response.

Hereditary hemorrhagic telangiectasia (Osler-Weber-Rendu disease) is a familial disease that is characterized by delicate, ectatic vessels in the skin, mucous membrane and viscera. These patients have a generalized vascular derangement including pulmonary A-V fistula and angiomatosis. Episodes of hemorrhage in cornbination with a familial history and cutaneous telangiectasia are diagnostic. We preaented a typical case of hereditary hemorrhagic telangieetasia in a 3-year-old female who had. two episodes of hemoptysis and compatible telangiectatic skin lesion. Her pulmonary and hepatic angiornas were also proved by pulmonary and aortic angiography.
