Studies were performed to evaluate the effect of unilateral nephrectomy on glycerol-induced acute renal failure in the rat. Normal rats were subjected to either sham uninephrectomy (n = 43) or right uninephrectomy (n = 53). The functional compensation of the remaining kidney was followed after 1 and 2 weeks. Fourteen days after the operation, acute renal failure was induced by injection of 50% glycerol solution to both groups. Uninephrectomised rats developed a lesser degree of renal failure compared to sham-operated rats. Forty-eight hours after glycerol injection, PCr of uninephrectomised rats was 260 +/- 22 mumol/l compared with 338 +/- 26 in sham-operated rats (P less than 0.0125) and CCr in uninephrectomised rats was greater (0.10 +/- 0.01 ml/min vs 0.07 +/- 0.01; P less than 0.025) in sham rats. Uninephrectomised rats had significantly greater recovery of CCr compared to sham rats at 24 h (20.1% +/- 2.3 vs 13.1% +/- 2.2, P less than 0.025) and at 48 h (32.1% +/- 3.3 vs 19.2% +/- 3.3, P less than 0.005) after glycerol injection. FENa was significantly less in uninephrectomised rats: 0.96 +/- 0.16% vs 2.25 +/- 0.05% (P less than 0.025) in sham rats 24 h post glycerol. Urinary excretion of K+ was greater in rats following uninephrectomy compared to sham rats both after 24 h and 48 h post glycerol (P less than 0.01), accompanied by lower plasma potassium (P less than 0.05). A correlation coefficient (r) of 0.793 was observed between urinary potassium excretion rate and percentage recovery of CCr.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

OBJECTIVE: To evaluate the influence of gravidity on the results of in vitro fertilization (IVF)-embryo transfer (ET) cycles. PATIENTS AND METHODS: All consecutive women aged <35 years admitted to our IVF unit from January 2002 to December 2004 were enrolled in the study. Only patients undergoing one of their first three IVF cycle attempts were included. Gravidity, ovarian stimulation characteristics, number of oocytes retrieved, number of embryo transferred and clinical pregnancy rate were assessed. RESULTS: Three hundred and forty-two consecutive IVF cycles were evaluated. One hundred and sixty-one cycles were from nulligravidas and 181 from women with a history of at least one previous clinical pregnancy. Forty-eight (29.8%) clinical pregnancies were observed in the nulligravida group and 56 (30.9%) in the gravida group. There were no differences between nulligravidas and gravidas in causes of infertility, length of ovarian stimulation, peak estradiol and progesterone levels, number of oocytes retrieved, fertilization rate and number of embryos transferred. Gravidas were significantly older (30.4 vs. 27.6 years, p < 0.001) and used more gonadotropin ampoules (36.1 vs. 31.8, p < 0.004) compared with the nulligravidas. CONCLUSIONS: Patient gravidity has no influence on the likelihood of achieving pregnancy in IVF-ET cycles. 相似文献

Thirty patients with Gaucher's disease have been examined in the authors' clinic; 29 of them suffered from the adult form and one had the juvenile type of the disease. The authors found intraocular abnormalities in four patients: three suffered from uveitis and in one, multiple vitreous opacities were observed. Two of the three patients had bilateral uveitis, while in one the uveitis was confined to the right eye only. In two of the three patients the manifestations of Gaucher's disease were present before the onset of uveitis. In one of the three, however, bilateral uveitis with spontaneous hyphema in the left eye was the presenting symptom. The diagnosis of Gaucher's disease in this case was arrived at during the work-up investigations for the etiology of the ocular manifestations. Initially the ocular symptoms in these three patients manifested as acute anterior uveitis, becoming chronic and involving also the posterior segments at a later stage. 相似文献

PURPOSE: To evaluate the role of 3-D US measurement of the endometrium during early IVF-pregnancy and before the appearance of gestational sac in the prediction of pregnancies outcome. METHODS: 60 pregnant women following IVF treatment were included in the study. The women underwent transvaginal 3D US measurements of endometrial volume and thickness on day 15-17 post ET. Patients were followed and classified according to pregnancy outcome into 2 further groups. The group with early pregnancy loss and the group with ongoing pregnancy. RESULTS: While no differences were observed between those who miscarried and those who did not in gestational age, endometrial thickness or volume, spontaneous early pregnancy loss was significantly higher in patients with endometrial volume <2 mL as compared to those with endometrial volume >2 mL. CONCLUSIONS: 3-D US measurement of endometrial volume of less than 2 mL during early IVF pregnancy and prior to the appearance of gestational sac is a powerful predictor of pregnancy loss. 相似文献

AIMS: To quantify the relative risk associated with lymphvascular space involvement (LVSI) on outcome measures in patients with apparent stage I endometrial cancer. METHODS: Six hundred and ninety nine consecutive patients with endometrial carcinoma apparent stage I, who underwent surgery in one of four gynecological oncology centers in Israel, comprised the study population. Forty cases with and 659 without LVSI were followed for a median time of 39 months. Recurrence free, disease specific and overall survival was compared between the two groups. The effect of LVSI, adjusted for other clinical and histo-pathological prognostic factors, was assessed by multivariate analysis. RESULTS: The univariate Kaplan-Meier procedure for survival analysis showed that patients with LVSI had lower recurrence free survival (p=0.0003), worse disease specific (p=0.0007) and overall survival (p<0.0001). Cox proportional hazards model demonstrated a trend toward shorter recurrence free survival (HR=2.0, 95% CI 0.9, 4.5; p=0.08), a worse disease specific survival (HR=2.8, 95% CI 1.1, 7.4; p=0.04) and decreased overall survival (HR=2.0, 95% CI 1.1, 3.8; p=0.03) in cases with LVSI. CONCLUSIONS: In patients with apparent stage I endometrial cancer the presence of LVSI, an independent poor prognostic factor, is associated with a two fold increased risk of death. The presence of LVSI warrants consideration when deciding upon post operative management. 相似文献

A 34-year-old patient, gravida 7, para 0, with three consecutive spontaneous abortions followed by four recurrent molar pregnancies is described. The patient conceived only with clomiphene citrate or human gonadotropin treatment. The occurrence of molar pregnancies succeeded spontaneous abortions with one remaining pregnancy progressing to gestational trophoblastic disease. The role of clomiphene citrate and human gonadotropins in the pathogenesis of this disease is discussed. 相似文献

Second primary malignancy in endometrial carcinoma patients 总被引:1,自引:0,他引:1
An epidemiologic study of multiple primary malignant neoplasms in endometrial cancer patients in Israel is presented. During the 7-year period of the study, 104 patients (10.3%) out of 1007 patients diagnosed as having endometrial cancer had another primary cancer. There was a significant difference in the incidence of multiple primary cancers between various ethnic groups, women of European/American origin having higher incidence than women of Asian/African origin. A significantly higher than expected incidence of second primary cancers occurred at the following sites: breast (relative risk, 4.1), ovary (relative risk, 11.6), cervix (relative risk, 5.1), and colon (relative risk, 5.9). The prognosis was mainly influenced by the site of the second primary cancer. The increased incidence of multiple primary malignancies justifies a high level of alertness to the possibility of second primary cancer in endometrial cancer patients. 相似文献

OBJECTIVE: We determined the effect of hypoxic conditions on cellular differentiation and prostaglandin H synthase expression in cultured human term trophoblast. STUDY DESIGN: Cytotrophoblasts isolated from term placentas were cultured for 24-72 hours in a standard (20% oxygen) or hypoxic (1% to 2% oxygen) atmosphere. Trophoblast biochemical differentiation was determined by release of human chorionic gonadotropin. Morphologic differentiation was evaluated by epifluorescent and confocal microscopic examination of cultures after dual cytochemical staining for surface membrane desmosomes and intracytoplasmic nuclei. Prostaglandin H synthase 2 expression was determined by Western blot analysis and correlated with enzyme activity by immunoassay of 2 prostaglandin H synthase 2 products, prostaglandin E2 and thromboxane. RESULTS: Human chorionic gonadotropin levels in media and syncytiotrophoblast formation were markedly diminished in trophoblast cultured in hypoxia, compared with trophoblast in control cultures, whereas viability was unchanged. Hypoxia up-regulated expression of trophoblast prostaglandin H synthase 2 but not of prostaglandin H synthase 1 and increased prostaglandin E2 and thromboxane release. CONCLUSIONS: Hypoxia limits differentiation and enhances prostaglandin H synthase 2 expression in cultured villous trophoblast. These responses may account for the cytotrophoblast prominence characteristic of placentas exposed to attenuated oxygen delivery. 相似文献

OBJECTIVE: To determine the demographic and clinical variables characteristic of non-epidemic intrapartum or puerperal group A streptococcal (GAS) infection. METHODS: The records of 47 patients diagnosed with intrapartum or puerperal GAS infection over a 6 1/2 year period at Hadassah-University Hospital-Mt. Scopus, Jerusalem were reviewed. Data regarding 25,811 women, the general population of women that delivered during that period, were obtained from their computerized medical records. Frequency distributions, t-test, chi-square, and Spearman's Rank Correlation were used, as appropriate, to analyze and compare demographic and clinical variables associated with development of GAS infection, its clinical course and subsequent development of septic shock. RESULTS: Mean age of mothers with GAS infection was higher than that of our general pregnant population (30.4 versus 27.4 years, P = 0.0019), and a higher proportion of GAS infected patients (30% versus 12%, P < 0.005) experienced PROM. Thirty-one (66%) women had fever as their sole presenting symptom, eight (17%) had fever and abdominal pain, seven (15%) had fever and abnormal vaginal bleeding, and one patient (2%) presented with a rash. Three patients (6%) developed a septic shock. Two of these patients presented with symptoms more than 14 days after delivery. CONCLUSIONS: We describe the characteristics of non-epidemic intrapartum or puerperal GAS infection. Data from our study and review of the literature suggest that some patients who develop septic shock may present later in the puerperium than patients with an uncomplicated GAS infection. 相似文献
