OBJECTIVE The aim of this study was to analyze the effect of transdermal estradiol replacement therapy (HRT) on immune function in menopausal women. STUDY DESIGN A prospective comparative study was carried out in 30 women, aged 48-55 years, who were divided into two groups; 20 of them received transdermal estradiol 50 microg/day during 3 months and 10 who(More)
BACKGROUND The definition of biochemical cure in acromegaly involves both the normalization of IGF-1 and a glucose-suppressed GH level of < 1 ng/ml. These criteria were reached by several consensus meetings, although no evidence-based recommendations as to the optimal time to perform biochemical evaluations were made, nor was the fact that several patients(More)
AIM Fetal intrauterine growth retardation (IUGR) is one of the most common obstetric problems, with a frequency of 12% in Mexico. In the past, investigations have focused on extrinsic causes of IUGR. More recent studies have examined the intrinsic factors that cause fetal intrauterine growth. Maintenance of fetal growth has been attributed to insulin-like(More)
The effect of thyroid hormone excess on glucose tolerance as well as insulin secretion and its peripheral action has been a matter of debate for many years. Thyrotoxicosis caused by Graves' disease is associated in some patients with impaired glucose tolerance and insulin resistance. The objective of the present study was to investigate if the insulin(More)
OBJECTIVE Decreases in circulating growth hormone (GH) and its main biological messenger insulin-like growth factor-I (IGF-I) have been interpreted as part of the aging process. Because estrogens participate in modulating GH synthesis and secretion, hypoestrogenism in menopausal women may lead to GH deficiency. The aim of the present study was to determine(More)
OBJECTIVE To demonstrate if GH concentrations and molecular heterogeneity of GH correlates with the presence of galactorrhea in normoprolactinemic women with normal ovarian function. DESIGN Aliquots of sera from women with normal ovarian function and normoprolactinemic galactorrhea were subjected to gel filtration chromatography, and the fractions were(More)
Gestational diabetes is considered as a carbohydrate intolerance, first diagnosed during pregnancy. A previous stage of carbohydrate impairement may precede its abnormality; therefore it may be convenient to establish some management in order to avoid the gestational diabetes. Six pregnant women who had moderate elevated level of blood glucose at fasting(More)
OBJECTIVE To determine whether cord sera leptin and components of the somatotropin axis - growth hormone (GH), total (t) and free (f) insulin-like growth factor (IGF), IGF-binding protein-3 (IGFBP-3), and insulin - correlate with birth weight. DESIGN Cross-sectional study of 22 newborns, 12 with normal birth weight (NBW) and 10 with low birth weight(More)
Size heterogeneity of immunoreactive prolactin (PRL) was studied in serum samples obtained from eight normoprolactinemic women during the menstrual cycle and five additional patients at pregnancy and lactation. Gel filtration of sera from women with normal ovarian function tested at day 10-12th of their menstrual cycle showed two predominant PRL forms,(More)
The speciation and partitioning of mercury from two Spanish pulverized coal (co) combustion (PCC) power plants equipped with wet limestone-based flue gas desulphurization facilities (FGD) have been evaluated in this work. The results were obtained by simultaneously sampling the solid, liquid and gaseous streams in the power plants and by determining the(More)
