OBJECTIVE: This study was performed to investigate whether 1) estrogen induces the change of vascular tone in endothelium-denuded human uterine artery, and 2) endothelium-independent vascular reactivity may be mediated by intracellular calcium ion modulation. METHODS: The uterine arteries from 34 premenopausal women were obtained at the time of hysterectomy due to various indications and endothelium was denuded. Vascular reactivity was monitored by using Isometric force transducer and recorded by physiograph. Endothelial integrity was assessed by sequential administration of 1micrometer norepinephrine(alpha-adrenergic stimulant) and 10 micrometer acetylcholine (endothelium -dependent vasorelaxant). Integrity of smooth muscle was measured by administration of 10 micrometer sodium nitroprusside (endothelium - independent vasorelaxant) and 10 micrometer tamsulosin(alpha-adrenergic blocker). A dose-dependent action of estrogen was measured on denuded uterine arteries, pretreated with norepinephrine and potassium chloride. In media contained denuded uterine arteries pretreated with 70mM potassium chloride and estradiol(3X10-5M), nitric oxide and its inhibitor, N-nitro-L-arginine methyl ester(L-NAME) was administered, respectively, in order to verify the vasodilation effect. Statistical tests were performed at the 5% level of significance using the SPSS PC+ package. RESULTS: Acethylcholine has little effect but sodium nitroprusside & talmsulosin showed marked relaxation, which suggested loss of endothelial function and adequacy of smooth muscle function. The contraction by norephinephrine(1 M) revealed estrogen induced relaxation which was concentration-dependent from 3 10-8M to 3 10-5M in concentration of 17 -estradiol. The contraction by high potassium solution 70mM was also inhibited by estrogen in concentration-dependent manner. This vasorelaxant effect of estrogen on endothelium-denuded uterine artery was not affected by addition of nitric oxide(NO) precursor, L-arginine and nitric oxide synthase(NOS) inhibitor, L-NAME. CONCLUSION: The results of this study revealed that estrogen has vasorelaxant effect on endothelium endothelium-denuded uterine artery by calcium antagonistic property through direct inhibitory effect on receptor- and voltage dependent calcium ion channels of smooth muscles. This vasorelaxant effect of estrogen on endothelium-denuded uterine artery was NO independent.

BACKGROUND: Following the improvement of the economic status and increasing medical availability, the interest for the public health and nutrition in elderly is increasing in Korea. It is well known that aging is associated with the deterioration of nutritional status, but in Korea, there were no clear data about that yet. PURPOSE: This study was performed to identify the normal distribution of the nutritional indices such as biochemical and anthropometric variables, showing the association between nutritional risk factor and aging. METHODS: Among 151,000 subjects over 40 year olds in Jung-Up County, Korea, 1051 were selected for a random cluster sample. After the blood tests and anthropometric measurements were performed during Dec 1996 to Feb 1997. RESULTS: Of the 1051 subjects(M:F=410:641), 340 were over 65 years(elderly) at the enroll time, while 711 were between 40 to 65 years(middle aged). Triceps skin fold thickness(TSF), body mass index(BMI), hematocrit(Hct) serum protein and albumin showed a weak negative correlation with age, whereas not in the case of the waisthip ratio(WHR), leucocytes, serum cholesterol and creatinine. Compared with middle aged with elderiy, TSF, BMI, albumin showed a significant differences(p<0.05). CONCLUSION: We showed the normal distribution of the variable nutritional indices and their changes associated with aging in the ambulatory elderly Korean living in the rural community. It needs further follow-up study including association with mortality.

Primitive neuroectodermal tumors (PNET) of the ovary are rare tumors with an exclusive or almost exclusive malignant neuroectodermal composition, and are generally regarded as a monodermal expression of an ovarian teratoma. The tumors are basically identical with the lesions of the same name occuring typically in the central nervous system of children. These tumors consist chiefly of undifferentiated small cells resembling neuroblasts. There are also mature, well- differentiated neuroectodermal cells, such as astrocytes and ependymal cells. We report a case of ovarian PNET with glial and neuroblastic differentiation and focal teratomatous foci of non-neural tissue in a 17-year-old female.

Among 666 premature infants or low birthweight infants who were admitted in NICU of St. Francisco General Hospital from January 1990 to Jun 1992, 96 infants were diagnosed as retinopathy of prematurity by indirect ophthalmoscope. The result were follows: 1) Among 666 patients, retinopathy of prematurity developed in 96 patients(14.1%) 2) The high incidence was observed in low birthweight and small gestational age. 3) Mean age of first diagnosing time was 42.0( 12 day of life and mean gestational age was 31.8 2.5 weeks and mean birthweight was 1646.5 (350.7gm. 4) In gestational age, birthweight and duration of oxygen therapy, there was statistically difference between cryotherapy group and spontaneous regression group. Other possible risk factors-hyaline membrane disease, apnea, anemia-were showed higher incidence in cryotherapy group. 5) Among the 20 infants who were treated with cryotherapy, 16 infants (80%) showed regression of neovascularization.

The peripheral neuroepithelioma is a primitive neuroectodermal tumor arising from peripheral nerve. This tumor is exceedingly rare and various authorities have estimated its incidence as less than 1% of all malignant tumors of peripheral nerve. As far as our knowledge is concerned, no report on the peripheral neuroepithelioma has been published in Korea. In June, 1985, we experienced a case of peripheral neuroepithelioma that arose in scalp in a 56 year old female. Clinical data and histopathological findings with light and electron microscope of the case were discussed and a brief review of the literature on this entity was made.

BACKGROUND/AIMS: Transforming growth factor-a(TGF-a) is a polypeptide cytokine related to cell proliferation and transformation. TGF-a binds to EGF receptor and stimulating DNA synthesis in liver cell. The hepatitis B virus (HBV) by itself is also believed to play a role in the hepatic carcinogenesis. Recently, it was reported that TGF-a and HBV were synergistic in action with rapid appearance of hepatocelluar carcinoma in bitransgenic mice. Although TGF- a is thought to play an important role in hepatocarcinogenesis, its expression during the natural history of HBV hepatitis was poorly understood. This investigation was performed to elucidate the dynamic changes and istinct immunohistochemical staining patterns in the course of chronic HBV hepatitis with specific reference to hepatocelluar carcinoma and to explain the role of TGF-a in the pathogenesis of hepatocelluar carcinoma. MATERIALS/METHODS: Employing TGF-a monoclonal antibody, signal detection was carried out by peroxidase-conjugated streptavidin in deparaffinized liver tissue sections taken from HBsAg positive patients. All of the liver tissue sections were proven HBV DNA positive by in situ hybridization. Immunohistochemical staining was performed in the tissue sections obtained from four normal controls, six from patients with chronic persistent hepatitis, five with chronic active hepatitis, eight with liver cirrhosis and eleven with hepatocellular carcinoma. RESULTS: The patterns of TGF-a immunoreactivity were cytoplasmic-grain types in normal controls and chronic persistent hepatitis, honeycomb types in chronic active hepatitis, occasional cytoplasmic-flooding types in liver cirrhosis, and cytoplasmic-grape types in hepatocellular carcinoma. A Shapiro-Wilk W test for frequency table analysis for the expression of TGF-a in these different disease groups was statistically significant. CONCLUSION: These data suggest that step-wise distinct expression of TGF-a enhancement in HBV associated chranic liver diseases which eventually resulted in the development of hepatocellular carcinoma were conceivably due to dysregulation of liver cell cycles by both HBV and TGF-a during the persistent repetition of cell cycles.
