Hypersensitivity to drugs is a complex diagnostic challenge. Detailed medical history remains the mainstay of drug hypersensitivity evaluation, which further determines diagnostic procedures, especially the types of skin tests to be performed. The current paper presents the case of a female patient with coexisting features of supposed immunoglobulin E (IgE) dependent allergic hypersensitivity t...

We and others have previously demonstrated that nociception in the mouse is heritable. A genetic correlation analysis of 12 common measures of nociception among a common set of inbred strains revealed three major clusters (or ‘types’) of nociception in this species. In the present study, we re-evaluated the major types of nociception and their interrelatedness using ten additional assays of noc...

Changes in mood, plasma progesterone concentration, urinary volume, sodium excretion, sodium:potassium ratio, and body weight during the menstrual cycle were determined in 18 women with premenstrual syndrome and 10 symptomless (control group) women. Plasma progesterone concentration was higher in the women with symptoms during the postovulatory phase of the cycle, and the peak progesterone conc...

Progesterone suppresses uterine contractility acting through its receptors (PRA/B). The mechanism by which human labour is initiated in the presence of elevated circulating progesterone has remained an enigma since Csapo first theorized of a functional withdrawal of progesterone in 1965. Here we report that in vitro progesterone-liganded nuclear PRB forms a complex including JUN/JUN homodimers ...

Abstract It is widely accepted that the prevalence of metal hypersensitivity increasing. Furthermore, incidence unerupted mandibular second molars 2.3%, which 0.2% judged to be a result impaction. While it becoming more common treat impacted in daily clinical practice, hypersensitive patients presenting with are less frequently encountered. There have been no previous reports who required molar...

INTRODUCTION The present study aimed to determine if, as occurs in female rats, progesterone attenuates cocaine-induced reward and psychomotor responses in male rats. METHODS The role of progesterone in the acquisition and/or expression of cocaine-induced conditioned place preference (CPP) and locomotor responses of intact male rats was studied. For chronic progesterone treatment, rats receiv...

BACKGROUND The steroid hormone progesterone is indispensable for mammalian procreation by controlling key female reproductive events that range from ovulation to implantation, maintenance of pregnancy and breast development. In addition to activating the progesterone receptors (PRs)-B and -A, members of the superfamily of ligand-dependent transcription factors, progesterone also elicits a varie...

Progesterone, a key female sex hormone with pleiotropic functions in maintenance of pregnancy, has profound effects on regulation of immune responses. We report in this work a novel function of progesterone in regulation of naive cord blood (CB) fetal T cell differentiation into key T regulatory cell (Treg) subsets. Progesterone drives allogeneic activation-induced differentiation of CB naive, ...

OBJECTIVE To compare progesterone concentrations in serum and endometrial tissue from hysterectomy specimens after vaginal or intramuscular (IM) administration of progesterone gel. METHODS This was a randomized open study of 14 post-menopausal women undergoing transabdominal hysterectomies. Participants received either vaginal progesterone gel, 90 mg, or IM progesterone, 50 mg, at 8:00 AM and...

For rat pituitary cells, progesterone receptor (PR) protein localizes to gonadotropes and PR messenger RNA is induced by E2 and rapidly but transiently down-regulated by progesterone. Here we quantitatively establish the down-regulatory effect of progesterone on PR protein and evaluate possible mechanisms. Nuclear PR-immunoreactivity (PR-IR) in gonadotropes, identified by dual immunofluorescenc...
