Unlike plants, fungi cannot synthesize their own food using energy from the sun. Instead, they must draw their food from a source--sometimes a tree. Fungi extend fibers into the host plant, absorbing its nutrients and depleting its energy, causing the tree to decline.
Hydroxyzine (/haÉªËdrÉksÉ¨ziËn/ ; sold as Vistaril, Atarax) is a first-generation antihistamine of the diphenylmethane and piperazine class.It was first synthesized by Union Chimique Belge in 1956 and was marketed by Pfizer in the United States later the same year, and is still in widespread use today.ydroxyzine's predominant mechanism of action is as a potent H1 receptor inverse agonist (K i = 2 nM). Unlike many other first-generation antihistamines, it has very low affinity for the mACh receptors (K i and in accordance, has a low propensity for producing anticholinergic side effects.
Examples of anticholinergic drugs include: Cogentin (benztropine): Anti-Parkinson drug as well as a medication to reduce the extrapyramidal side effects of antipsychotic medications.Atropine: Medication used to treat abnormal heart rates & arrhythmias. Also used as a preoperative medication.n anticholinergic drug is a drug that blocks acetylcholine receptors, resulting in side effects such as decreased GI motility (constipation), decreased sweating, urinary retention, dry eyes, dry mouth, & dilated pupils &/or blurred vision.
