Skin aging is a process influenced by several factors, including estrogen. Estrogen modulates the physiology of skin, and its deficiency in postmenopausal women accelerates skin aging. Administration estrogen can delay process. Phytoestrogens are estrogen-like compounds derived from plants that administered via oral as well astopical routes. Trigonella foenum-graecum, commonly known fenugreek, ...

background: diazinon is a widely used organophosphate insecticide which is applied against plant pests. this compound has various side effects because it acts as an acetyl cholinesterase enzyme inhibitor. objective: the aim of present study was to investigate the effects of diazinon on pituitary–gonad axis and ovarian histological changes in rats. materials and methods: in total 50 female wista...

introduction: impaired wound healing in diabetic patients is a major clinical problem, which is associated with significant morbidity and mortality. estrogen has positive effects on neoangiogenesis, reepithelialization and cell proliferation. in this research, effect of estrogen on wound healing in diabetic male rats was investigated. methods: this study was performed on male wistar rats (body ...

introduction: estrogen is one of the female sex hormones that in addition to its reproductive role, has favorable fects on the metabolism of blood lipids and lipoproteins and by this way decreases the coronary heart disease. n the other hand, phytoestrogens are phytochemical substances that have effects like estrogens. isoflavones, hich the most important of them is genistein, are the most comm...

this study aimed to explore and validate a new juvenile osteopenic (jo) rat model then examine the efficacy of moghat (glossostemon bruguieri) as an alternative reversal therapy for jo. phytochemical screening analysis showed that moghat contains 5.8% alkaloids, 1.5% flavonoids and 13.2% total phenols. juvenile osteopenia was induced in 15 days old sprague- dawley female rats by feeding them fr...

Abstract Resveratrol obtained in grape seed and skin is structurally similar to a synthetic estrogen diethylstilbestrol. The endogenous estrogen, 17β-estradiol, induces cellular responses by binding the receptor alpha beta. bone fracture due decreased mineral density postmenopausal women linked reduced estrogen. adverse drug reactions of hormone replacement therapy warrant identifying unique na...

alzheimer’s disease (ad) is a disorder with multiple pathophysiological causes, destructive outcomes, and no available definitive cure. pelargonidin (pel), an anthocyanin derivative, is an estrogen receptor agonist with little estrogen side effects. this study was designed to assess pel memory enhancing effects on the a rat amyloid beta 25-35 (aβ) intrahippocampal microinjections model of ad in...

In estrogen-dependent rat adrenocortical carcinomas, thymidine kinase activity decreased during tumor regression following removal of estrogen from the host. The change in the kinase activity could be prevented by estrogen administration but not by the administration of growth hormone or adrenocorticotropic hormone. The alterations in kinase activity were not due to changes in the activity of c...

The enzyme kinetics of estrogen 2-hydroxylase from rat liver microsomes has been investigated using two radiotracer methods. The conversion of [4-14C]estradiol to [4-14C]2-hydroxyestradiol by microsomes was examined by isolation of the catechol estrogen. [6,7-3H]2-Hydroxyestradiol was prepared and added at the end of the incubation as a recovery marker for quantitation. Initial velocity conditi...
