OBJECTIVE To provide a comprehensive overview of the risk of venous thrombosis in women using different combined oral contraceptives. DESIGN Systematic review and network meta-analysis. DATA SOURCES PubMed, Embase, Web of Science, Cochrane, Cumulative Index to Nursing and Allied Health Literature, Academic Search Premier, and ScienceDirect up to 22 April 2013. REVIEW METHODS Observational...

Liver tumor formation in rats treated with oral contraceptive steroids for long periods has been associated with the tumor promoting potential of these agents. As other known liver tumor promoters, e.g., phenobarbital and hexachlorocyclohexane, induce liver growth and hepatic monooxygenases, we investigated whether or not estrogens have similar effects. Female rats were treated with a wide rang...

The present study was designed to investigate the effect Hypericum Perforatum (HP), on behavioral changes, corticosterone, TNF-α levels and tryptophan metabolism and disposition in bilateral ovariectomized rats compared to 17α -ethinylestradiol. Behavioral analysis by measuring immobility time in forced swimming test and open field test, serum and hippocampal corticosterone and TNF-α along with...

In this study, Ethinylestradiol was removed from aqueous solution (maximum removal 83.1%) by hydrothermally carbonized and steam activated carbon adsorbent prepared palm kernel shells. The effects of varying mass, pH, temperature concentration on adsorption were studied. It found that pseudo second order kinetic model is able to describe well the Ethinylestradiol. Thermodynamic studies showed p...

Background: Ethinylestradiol (EE) has induced cholestasis and hepatotoxicity in animal studies through reducing bile acid uptake by hepatocytes and induce of oxidative stress. Pentoxifylline (PTX) is a drug that by inhibition of release or transcription of proinflammatory cytokine cause prevents oxidative stress of liver cell and reduction of damage. We aimed to evaluate the effects of pentoxif...

Methods The objective of this review was to evaluate currently available low-dose OCs containing ethinylestradiol and different progestogens in terms of contraceptive effectiveness, cycle control, side effects and continuation rates. The Cochrane Controlled Trials Register, MEDLINE and EMBASE databases were searched. Randomized trials reporting clinical outcomes were considered for inclusion an...

BACKGROUND As weight gain is one of the most frequently cited reasons for not using and for discontinuing hormonal contraceptives, in an open-label, single-arm, multicentre clinical study we evaluated the effect of the ethinylestradiol/norelgestromin contraceptive patch (EVRA, Janssen-Cilag International, Belgium) on body composition using bioelectrical impedance analysis (BIA). METHODS Body ...
