1.Correlation between Tumor Angiogenesis and Metastasis in Invasive Breast Carcinoma.
Nam Hoon KIM ; Moon Hyang PARK
Korean Journal of Pathology 1995;29(6):740-745
Tumor angiogenesis(TA) refers to the growth of new vessels toward and within a tumor. TA is necessary both at the beginning and at the end of the metastatic cascade of events. Recently, experimental evidence suggests that the growth of a tumor beyond a certain size requires angiogenesis. To investigate how tumor angiogenesis correlates with metastases in breast carcinoma, the microvessels were counted (per 200 / field) in the most active areas of neovas-cularization by two investigators. The microvessels within breast carcinoma were highlighted by in imunohistochemical staining for factor VIII-related antigen. Microvessel count(MVC) in node-positive carcinoma(59.66=35) was significantly higher than in node-negative carcinoma(44.76=17)(p=0.009). MVC was also statistically correlated with tumor size and stage, but not with histologic grading, DNA ploidy, or hormonal receptors(estro-gen and progesterone). MVC in invasive breast carcinoma may be one of many prognostic predictors of node-positive breast carcinoma. Assessment of tumor angiogenesis may therefore be valuable in selecting patients with early breast carcinoma for aggressive therapy.

The purpose of this study was to identify the degree of self-care activities of stroke patients, the family burden, and the educational needs of primary caregivers. A descriptive survey research was conducted in 97 stroke patients and their respective primary caregivers. Data were collected the using 26th to by interviews a structure questionnare from July August 5th, 1999. NIH stroke status was 12.15+/-8.40, the degree of self-care activities of stroke patients was 26.85+/-9.39. The score of objective burden of primary caregivers was 31.24+/-4.81 and subjective burden was 24.30+/-6.99. The score of the educational needs was 89.78+/-9.99. We present several imformations about clients from these scores as follows: The patients were convalescent and their depentant level of self-care was middle range: The objective burden was higher than the subjective burden: And the educational needs of family caregivers were very high. The Elain Mattis Educational Wants of Family Caregivers of Disabled Adults Questionnaire was used to assess the educational needs of primary caregivers of stroke patients. The results of this research are offered to help nurses understand the feelings of uncertainty about the new and unexpected role that family caregivers face and to help nurses meet the needs of families preparing to care stroke survivors at home.

Dariers disease is a domirantly inherited skin disease that is characterized by keratotic papules predominantly on the sebornieic areas, palmar pits, and a nail dystrophy. The diagnosis is difficult in the small group with flexural involvement because the features of flexural Dariers disease overlap clinically and histolopica.lly with those of Hailey-Hailey disease. The diagnosis of Dariers disease may be confirmed if the patient has the pathognomonic nail dystrophy. We presents a case of flexured. Dariers disease in a 65 year old woman. She has suffered from skin lesions which have some resemblance to those of Hailey-Hailey disease. We could diagnose her skin lesions as Dariers disease because she had the eharacteristic nail dystrophy.

BACKGROUND: We studied how periodic and complex heart rate dynamic changes as pulmonary artery pressure increases in 32 infants with ventricular septal defet. In addition, we tested the possibility that the dynamical changes can be used to noninvasively predict the pulmonary artery pressure. METHODS: During cardiac catherterization, mean pulmonary artery pressure was measured and, at the same time, 5minute segments of continous electrocardiographic recording was stored. High-(>0.15 hertz) and low-(0.03-0.15 hertz) frequency components of heart rate variability were computed using spectral analysis. Yhe overall complexity of heart rate time series was quantified by its approximate entropy. RESULT: Pulmonary hypertensive infants(mean pulmonary artery pressure>20mmHg, n=17) had significantly lower low-(p<0.05)and high-(p<0.05) frequency power and lower approximate entropy(p<0.0001) than pulmonary normotensive infants(mean pulmonary artery pressure20mmHg, n=15). The mean pulmonary artery pressure was significantly correlated not with the spectral powers but with approximate entropy(=-0.51, P=0.0001). Conclusion: It can be concluded that, in infants, pulmonary hypertension induced by left-to-right shunt lesions suppress both periodic and complex heart rate oscillation and that mean pulmonary artety pressure can be predicted by calculating approximate entropy of heart trate variability.

Cholesteatoma in the kidney and ureter are accumulations of waxy, gray flakes of keratin materials, secondary to squamous metaplasia of the transitional epithelium. Herein, we describe a case of cholesteatoma in the renal pelvis of a 69-year-old woman, and give a brief review of the literature. In the upper pole of the left kidney was a 6 cm cystic lesion filled with a thick, flaky, grayish, comified material. Microscopically, the cystic area showed calyceal and pelvic structures being replaced by keratinizing stratified squamous epithelium. The surrounding renal parenchyma was atrophic with features of chronic pyelonephritis.

Most neonatal cutaneous hemangiomatosis are complicated by visceral involvement and. are associated with a high mortality rate in the first month of life. Some neonates with multiple cutaneous hemangiomas, however, may follow a benign course of spontaneous resolution without visceral involvement. Such cases are called benign neonatal hemangiomatosis (BNH). BNH is characterized by a lack of mucosal or symptomatic visceral involvement. rapid spontaneous regression of cutaneous hemangimas, and an excellent prognosis. We report herein a case of BNH which is atypical compared to previously reported BNFI cases. Our patient had a more prolonged course than those of usual cases with BNH and showed a conjunctival involvement.

A quantitative assessment of the testicular biopsy, and serum hormone levels( testosterone, prolactin, and follicle-stimulating and luteinizing hormones) were studied in 10 spinal cord injured men and comparison of these parameters to normal controls were performed. The mean number of Sertoli cells, mature spermatids, tubular diameter and tubular wall thickness were determined in both groups and analyzed. In the spinal cord injury group the mean number of mature spermatids per tubule was significantly lower and the mean number of Sertoli cells per tubule was significantly higher than in controls(p<0.05). Serum testosterone and luteinizing hormone values were significantly higher in the spinal cord injury group than in controls(p<0.05). These significant differences of the quantitative parameters of the testicular biopsy and hormonal values that may contribute to the reproductive dysfunction.

It has been postulated that programmed cell death via apoptosis may be critical for remodelling of glomeruli after inflammatory injury. To understand the regulatory mechanism of apoptosis in experimental crescentic glomerulonephritis (CGN), we examined the MIB-1 score (proliferation index, PI) and apoptotic index during the progression of experimental CGN to end-stage renal failure. CGN was induced in New Zealand White rabbits by administration of guinea pig anti-GBM IgG after sensitization with guinea pig IgG and their kidneys were analyzed for the development of crescents through sequential renal biopsies. Serum creatinine levels progressively increased in a time course until day 45. The PI in glomeruli, tubular epithelial cells, and interstitium progressively increased during the progression of experimental CGN. The mean numbers of MIB-1 positive intraglomerular nuclei (PI) were significantly correlated with degrees of crescent formation and the numbers of apoptotic cells in the glomeruli, tubules, and interstitium. Significant apoptosis was present from day 1 (15.8 10.16 cells/glomerular cross section) and increased in number with the proliferative lesions as glomerular inflammation continued. Moreover, apoptosis increased during the resolution of the glomerular inflammation, and many apoptotic cells were present in the sclerotic lesions in day 17 (18.6 12.99 cells/glomerular cross section). As glomerular inflammation subsided, cellular crescents progressed to fibrous crescents with a reduction of cellularity by day 45. On day 45, the glomerular PI and the numbers of apoptotic cells were markedly decreased. The correlations found in CGN between the creatinine level and the percentage of crescents, between the percentage of crescent and PI, and between the PI and number of apoptotic cells support the hypothesis that there is a change in the glomerular and tubulo-interstitial apoptosis under pathologic conditions. These findings indicate that apoptosis plays an essential role in the resolution of intra- and extraglomerular inflammation and in the elimination of glomerular cells within the sclerotic regions for progressive CGN. The regulation of the apoptotic phenomenon and increased PI during CGN may be important in the progression of glomerular inflammation and the development of pathologic glomerular sclerosis.
