Partial hydatidiform mole and hypertension associated with a live fetus--variable presentation in two cases

Partial hydatidiform mole associated with live births is a rarecondition. There are not enough cases in the literature to allowthe assessment of comprehensive risks to be made and upon whichmanagement policies can be based. Several clinical dilemmasarise following diagnosis of a viable pregnancy associated withmolar tissue. We present two cases demonstrating the problemsand suggest management based on outcome and a review of theliterature.     

彩色多普勒超声检测妊高征血流速度比值的临床意义

目的：通过对妊高征（PIH）胎儿脐动脉（UmA)，大脑中动脉（McA)及孕妇子宫动脉（UtA)速度比值的检测，探讨其在预测围产儿结局中的价值。材料与方法：应用彩色多普勒超声测定48例妊高下及60例正常中晚期妊娠胎儿UmA,McA及孕妇UtA的S／D值，分析正常妊娠与不同程度妊高征S／D值的变化以及S／D值与围产儿结局的关系。结果；妊高征时胎儿Uma,McA及孕妇UtA的S／D值有不同程度变化，尤以重度妊高征S／D值变化最明显，表现为胎儿UmA,UtA的S／D升高，McA的／SD值降低，UmA S/D值改变敏感于UtA,McA；而McA的S／D值对围产儿结局有更好的预报的S／D值升高；McA的S／D值降低；UmA S/D改变敏感于UtA,McA，而McA的S／D值对围产儿结局有更好的预报价值。结论：本研究为脐动脉，大脑中动脉及子宫动脉速率比值监护妊高征胎儿宫内状况，预测围产儿结局提供理论依据。     

先兆子痫肾病的临床病理研究

目的探讨先兆子痫肾病及妊娠期蛋白尿的肾组织病理变化和临床特点。方法在1999年～2002年间,本院20例临床诊断为先兆子痫或妊娠期蛋白尿的住院患者在分娩后5d～3个月内行经皮肾穿刺活检,其中1例半年后重复肾活检。肾组织分别送光镜、免疫病理及电镜检查,分析临床病理特点并长期门诊随访。结果单纯先兆子痫肾病16例,表现为典型内皮细胞病,伴轻、中度系膜细胞增生;免疫荧光阴性或IgG、IgM和C3弱阳性,其中1例合并局灶肾小球硬化(FGS),该例1年后仍有少量尿蛋白(0.49g/24d),其余15例均在分娩后3～6个月尿蛋白完全阴转。IgA肾病合并先兆子痫肾病1例,分娩后尿蛋白明显减少,但仍有持续镜下血尿,半年后重复肾活检小球内皮细胞病变消失。单纯IgA肾病1例,因持续大量蛋白尿需接受肾上腺皮质激素及免疫抑制剂治疗。轻度系膜增生性肾炎1例,呈蛋白尿及血尿表现。I期膜性肾病1例,分娩后尿蛋白亦明显减少。结论先兆子痫肾病其病理特征为典型内皮细胞病,常可在分娩后半年内完全恢复正常,合并FGS可能使恢复延迟。妊娠加重原发性肾脏病变,分娩后肾脏损害减轻。产后及时肾活检是安全的,有助于早期确诊、指导治疗及判断预后。     

Prooxidant-Antioxidant Factors in the Blood of Pregnant Women with Late Gestosis of Different Severity

Prooxidant-antioxidant factors were studied in the blood of pregnant women with gestosis of different severity. Comparative study showed that activation of peroxidation and decrease in the antioxidant potential depend on the severity of gestosis.

CT findings in eclampsia

Summary Cranial CT was performed in five patients with eclampsia: densitometric modifications were present in all cases. Only one patient, who later died, displayed multiple foci of cerebral haemorrhage; all others presented bilateral, symmetrical, nonenhancing hypodensities with mass effect interpreted as cerebral oedema. At CT performed 7–14 days after interruption of the pregnancy, these characteristic hypodense lesions were no longer present while neurological symptoms disappeared.     

Lipid-Protein Complexes in Erythrocyte Membrane in Late Gestosis

Gestosis is characterized by increased rigidity of the surface and deep layers of erythrocyte membranes, impaired protein-lipid relationships, and imbalance between LPO and the antioxidant defense system. These changes determine the prognosis and complications of this condition.     

Cooperative Type of Platelet Hypersensitivity to ADP

We found that gestosis is associated with platelet hypersensitivity to ADP. Cell P2X1 receptors exhibited a positive cooperative response to ADP (EC₅₀=10.88±3.70 nM, Hill constant n=2.59±0.50 rel. units). Cooperative binding of ADP to platelet P2X1 receptors was also observed during incubation of cells from pregnant women with isosorbide dinitrate. __________ Translated from Byulleten' Eksperimental'noi Biologii i Meditsiny, Vol. 140, No. 9, pp. 261–264, September, 2005     

Effect of HLA-compatibility in married couples on the development and severity of gestosis

We studied the effect of histocompatibility in married couples on the development and severity of gestosis. It was found that gestosis more often develops in women with two common HLA alleles of class II major histocompatibility complex with her husband. The greatest number of coincidences was detected in subgroups with medium and severe gestosis. Perinatal outcomes in women with medium-severe gestosis having HLA-alleles common with husbands are characterized by delivery of babies with lower body weight.     

The significance of angiogenic growth factor in the pathogenesis of gestosis in pregnant women with varicose disease

Recently, a close relationship between angiogenesis processes, growth factor activity in vascular abnormalities, and gestosis was revealed. In the present study, the dynamics of serum vascular endothelial growth factor during pregnancy was studied in patients with varicose disease with and without gestosis and in healthy women. The level of vascular endothelial growth factor increased during normal pregnancy, but decreased in gestosis. In pregnant patients with varicose disease, a less pronounced increase in this parameter was observed in comparison with that in healthy women. __________ Translated from Byulleten’ Eksperimental’noi Biologii i Meditsiny, Vol. 145, No. 4, pp. 464–466, April, 2008     

Nitric oxide and HSP70 proteins during normal pregnancy,gestosis, and preclinical gestosis

We measured the content of NO metabolites in blood plasma and urine and concentration of HSP70 proteins in the plasma and leukocytes from 126 women with normal pregnancy, gestosis, and preclinical gestosis. In women with gestosis accompanied by NO deficiency the concentration of HSP70 proteins in the plasma increased more significantly than in leukocytes. These changes are an important marker of endothelial dysfunction and reflect the severity of cell damage during this disorder. The decrease in excretion of NO in the urine and increase in HSP70 protein content in leukocytes and plasma characterize endothelial dysfunction in women with preclinical gestosis.
