Sex hormones regulate cholangiocyte hyperplasia in bile duct-ligated (BDL) rats. We studied whether follicle-stimulating hormone (FSH) regulates cholangiocyte proliferation. FSH receptor (FSHR) and FSH expression was evaluated in liver sections, purified cholangiocytes, and cholangiocyte cultures (NRICC). In vivo, normal female and male rats were treated with FSH or immediately after BDL with a...
Organophosphorous pesticides (OPs) are suspected of altering reproductive function by reducing brain acetylcholinesterase activity and monoamine levels, thus impairing hypothalamic and/or pituitary endocrine functions and gonadal processes. Our objective was to evaluate in a longitudinal study the association between OP exposure and serum levels of pituitary and sex hormones. Urinary OP metabol...
BACKGROUND There are few data in the literature regarding the utility of metfomin before and during gonadotrophin administration in women with polycystic ovary syndrome (PCOS). The aim of the present study was to assess the effect of the pre-treatment and co-administration of metformin in infertile PCOS women treated with controlled ovarian stimulation (COS) followed by timed intercourse (TI) o...
IVF (in vitro fertilization) often represents the ultimate step in our attempt to treat infertility. Nowadays this method is more and more used, couple's expectations are higher and higher, so that optimizing the chance that one IVF pregnancy became a healthy newborn child is becoming an important issue. In this study we analyzed the controlled ovarian hyperstimulation impact on IVF pregnancy p...
A highly purified follicle-stimulating hormone from human pituitary glands has been prepared by ammonium sulfate and ethanol fractionation, gel filtration on Sephadex G-100, ion exchange chromatography on carboxymethyl cellulose, zone electrophoresis on cellulose columns, and preparative continuous flow polyacrylamide gel electrophoresis. The final product has shown lO,OOO-fold purification ove...

Highly purified N-acetyl-beta-D-hexosaminidase B from normal urine and urine of a patient with mucolipidosis III was used to determine whether it has undergone any of the alterations associated with this genetic defect. Examination by sodium dodecyl sulphate/polyacrylamide gel electrophoresis showed that both the enzyme preparations contained protein components with apparent Mr values of 55 000...
