Seasonal allergies are one of the most common ailments in couples undergoing In Vitro Fertilization (IVF). But many women are unclear whether they can use anti-histamines? To further complicate matters, some fertility forums discuss individual use of anti-histamines to improve pregnancy rates during IVF when patients have a history of recurrent pregnancy loss. Others strictly warn against anti-histamines, quoting a potential risk of vaso-constriction or reducing blood flow to the ovaries and uterus, as it acts in the nasal passages. So whats a woman to do?. At present, there are no well designed clinical studies that have evaluated the effect of anti-histamine use on fertility. Research has shown that there are histamine receptors in the uterus1, that human embryos secrete histamine2, and that the interaction of histamine from the embryo helps the embryo implant into the endometrium of the uterus. But, there is also one study showing that anti-histamines decrease blood flow to the uterus. So ...

Yes the digestive tract causes allergies. I had horrible head congestion. Tried all the meds, anti-histamines. Went to allergist. He said it was not connected to digestive tract. They tested me for allergies and said it was dust mites causing it all. Told me to take all this stuff, get special bed sheets. Anyway, I clear up some of my problems a bit, and improve 90%+ in the head congestion/allergy department.

My wife took Zoloft specifically for several years for mild depression, and as a direct result, she developed sub-cutaneous lupus, which she still has 9 years after stopping Zoloft. I myself took Zoloft and stopped after one month, as it, as I describe it, zombified me. I felt severely disassociated emotionally, had trouble concentrating, and felt like I had no drive or motivation. It was horrible, for me. I have suffered from generalized anxiety disorder and debilitating panic attacks since pre-adolescence, with slowly increasing severity and frequency to this day. It is difficult to get treatment, especially without insurance, and every time I have tried, doctors want to prescribe an SSRI first. Objections to SSRIs can often be seen as drug-seeking behavior, arrogantly off-putting, or even hypochondria, and has even resulted in prescriptions for useless drugs like anti-histamines (speaking from my own experience). The result is simply attempting to live with it by telling myself not to be ...

Do the buds of spring signal trouble to you? If so, you may be among the 20% of the population who suffer from spring hayfever. Hayfever, known medically as seasonal allergic rhinitis is the most common allergic disorder in Canada. It is characterized by nasal congestion, sneezing, red, itchy eyes, nose or throat, tearing, fatigue and the dark bags under the eyes (known as allergic shiners). For people allergic to pollen, grass, and weeds spring and summer are a mixed blessing. But allergic rhinitis can occur at any time of the year for people allergic to dust mites, feathers, and animal dander. Mold and fungus allergies typically flare up in the fall when the molds grow rapidly in the cool moist air. Think mold allergies if you suffer from sinusitis at the time of year when mushrooms are popping up underfoot.. Allergies are a reflection of a disordered immune system perceiving harmless substances as foreign invaders. The symptoms the body produces are its convoluted attempt to protect itself. ...

I took the bus in to work this morning as I do every day. I tend to spend the time plugged in -- either listening to music from Hype Machine, or scrolling through news from my Google Reader as I catch up on my day. This morning, I spent the ride listening and exchanging a few words with a homeless man on the bus with me.. He first entered my consciousness when I almost took his seat. He had been sitting on the step from the back door to the back section of the bus. I could see he needed the seat more than I did, and apologized for accidentally trying to grab it ahead of him.. That was enough of an opening for him to start talking. Memories of @trevoro having garbage juice dripping on his leg didnt necessarily make me want to engage. But I unplugged one ear and prepared to humour him. He began to tell a tale of suffering from summer allergies - no sleep, no money for anti-histamines, but needing anti-histamines so he could live. In this case, iiving meaning finding empties to collect.. He ...

Allergy symptoms are mostly caused by the release of histamine in response to allergens. The binding of histamine to the extracellular portion of the H1 receptor triggers a structural change of the transmembrane portion, leading to a change in the C terminal area. This c terminal region interacts with G proteins, leading to the activation of the Gq signalling pathway, which triggers allergy symptoms like itchy eyes and runny noses. Many allergy drugs are anti-histamines, in that they bind to the histamine receptor but do not cause the conformational change that leads to a response. ...

Homogenates of the rat cortex, striatum and mouse whole brain were prepared 1 h after subcutaneous injection of the H3 antagonists and incubated with [125I]iodophenpropit, a radiolabeled H3 receptor antagonist, to determine the H3 receptor occupancy. Specific [125I]iodophenpropit binding to the rat cortex and striatum was inhibited by thioperamide with IC30 values of 1.0 and 1.5 mg/kg, respectively. Clobenpropit also inhibited [125I]iodophenpropit binding, but was less ...

We investigated the effects of thioperamide, a histamine H3-receptor antagonist, on a scopolamine-induced learning deficit in the step-through passive avoidance test in mice, and on contents of acetylcholine and choline in the brain. In a behavioral study, thioperamide (20 mg/kg) alone slightly ameliorated scopolamine-induced learning deficit, and pretreatment with zolantidine, a histamine H2-receptor antagonist, significantly enhanced the ameliorating effect of thioperamide. This enhanced ameliorating effect of thioperamide was antagonized by pyrilamine, a histamine H1-receptor antagonist and (R)-alpha-methylhistamine, a histamine H3-receptor agonist, suggesting that thioperamide showed the ameliorating effect via histamine H3 receptors and/or histamine H1 receptors. In the biochemical study, thioperamide (20 mg/kg) in combination with zolantidine (20 mg/kg) significantly increased contents of choline in most of brain regions. These findings suggest that there is a close relationship between

N2 - Background: Unlike the effects of exogenous histamine, those of endogenous histamine on the lung mechanics have not yet been characterized. The site of endogenous histamine liberation by mivacurium was determined, as were the effects of this histamine on the airway and parenchymal mechanics in control rabbits (group C) and rabbits pretreated with H1 and H2 receptor blockers (group AH). The effectiveness of the receptor blockade was ensured by challenges with exogenous histamine. Methods: Pulmonary input impedance at low frequencies (ZL) was measured in anesthetized mechanically ventilated open-chest rabbits under control conditions and every minute after administration of an intravenous bolus of mivacurium (2 mg/kg) and exogenous histamine (10 μg/kg). Histamine levels were determined in serum samples taken from ...

Safety and tolerability were assessed by adverse events reported by subjects at each postrandomization clinic visit. We did electrocardiogram and laboratory examination before initiation of antihistamine therapy and each month after (complete blood count [CBC], aspartate aminotransferase [AST], alanine aminotransferase [ALT], creatinine, blood urea nitrogen). We did an specific questionnaire (in spanish) to assess sedation:. ¿Sientes más sueño o somnolencia de lo acostumbrado? (Do you feel more sleepy or drowsy than usual?), ¿Sientes que el sueño o la somnolencia interfiere con tus actividades diarias? (Do you feel sleep or sleepiness interferes with your daily activities?), ¿Sientes que tú sueño no es reparador? (Do you feel that you sleep is not restful?). Each question could be answered from 0 to 3 points (0 no 1. little, 2 moderate, 3 much). the sum of points defined them the severity of sedation in mild (0-3), moderate (4-5) and severe sedation (6-9). ...

Spring is the season of growth and renewal with some great weather for enjoying the outdoors before the heat of summer hits. However hayfever sufferers dont look forward to spring in the same way as it is usually when they reach for anti-histamines and tissues! Hayfever (also called allergic rhinitis) is a condition caused by the immune system reacting to airborne substances. Symptoms can occur all year around in Brisbane but are more prevalent in Spring, and can include sneezing; a runny or stuffy nose; itchy ears, nose and throat; itchy, red or watery eyes and often headaches. Because hayfever is triggered by an allergen it is often managed by anti-histamines which suppress the allergy symptoms. Other conventional treatments may include saline or medicated nasal sprays, eye drops, or immune desensitization therapy. There is a range of non-drug treatment options as well and the really exciting development is new research demonstrating the effectiveness of acupuncture for this ...

Just like any eczema or psoriasis afflicted individual born in the late 20th century under the auspices of western medicine, I had my bouts with drugs, anti-histamines and steroids. When I was around 5 to 6 I used to have respiratory asthma and was prescribed anti-histamines. At 16 I was injected with lots of steroids for cystic acne. When I got sand fly bites at 24 I got steroid injections and steroid creams. At 34-35 with my eczema I got steroids as well. None of them steroids ever worked.

The recent cloning and characterization of the human histamine H3 receptor cDNA marked a significant step toward a greater understanding of the role of this receptor in the central nervous system. We now report the cloning of the rat histamine H3receptor cDNA and demonstrate distinct pharmacological species differences. The rat cDNA clone encodes a putative 445-amino acid protein with 93% identity to the human H3 receptor. Northern blot analysis revealed a major single entity of 2.7-kb in length expressed only in brain. Transfection of the rat receptor cDNA into SK-N-MC cells conferred an ability to inhibit forskolin-stimulated cAMP formation in response to histamine and other H3agonists. N-[3H]methylhistamine saturably bound to transfected cells with high affinity (Kd = 0.8 nM). All agonists tested had low or subnanomolar Ki values similar to that for the human recombinant receptor. The antagonists thioperamide and clobenpropit also bound with high affinity (Ki = 4 and 0.4 nM, respectively). ...

In allergies, the immune system responds inappropriately to allergens, which are materials that trigger the reaction. These may be pollens, house dust, gluten, flea saliva, moulds, grass proteins, other foods, garden plants, house plants, food components, household reagents or certain chemicals. Removing or reducing these allergens from the environment or diet of the dog, cat or horse may reduce the symptoms but will not cure the problem. The underlying problem is an immune malfunction, which must be corrected before freedom from allergies can be established.. Any powerful immune challenges that are capable of perverting immune function and balance, such as virus or vaccination, are likely causes of the underlying allergic disorder.. In conventional medicine, it is usual to try to suppress the allergic reaction with anti-inflammatory drugs (such as steroid/cortisone) or with anti-histamines. This is a life-time task and can, in fact, lead to a worsening of the disease in the longer term. ...

Autacoids or autocoids are biological factors (molecules) which act like local hormones, have a brief duration, and act near their site of synthesis.[1] The word autacoid comes from the Greek autos (self) and acos (relief; i.e., drug). The effects of autacoids are primarily local, though large quantities can be produced and moved into circulation.[citation needed] Autacoids may thus have systemic effects by being transported via the circulation. These regulating molecules are also metabolized locally. In sum, these compounds typically are produced locally,[citation needed] act locally and are metabolized locally. Autacoids can have a variety of different biological actions, including modulating the activities of smooth muscles, glands, nerves, platelets and other tissues.[citation needed] Some autacoids are chiefly characterized by the effect they have on specific tissues, such as smooth muscle.[2] With respect to vascular smooth muscle, there exist both vasoconstrictor and vasodilator ...
