The inflammatory effect of some compounds (polyglycolamines and polyglycolalcohols condensated with various number of ethylene oxide groups) used in textile industry were investigated as to their action on skin vascular permeability in rats and histamine release from rat peritoneal mast cells. The intradermal injection of tested agents caused the inflammatory skin reactions of various intensity depending on time, dose and chemical structure of agent used. It has been also shown that these properties of tested compounds were correlated with their histamine releasing activity and seemed to be dependent on their chemical structure, namely, the number of ethylene oxide groups in molecule. It is suggested that the histamine release induced by tested compounds is of cytotoxic nature since it depends neither on metabolic energy nor on extracellular calcium.

Upon stimulation and activation, mast cells (MCs) release soluble mediators, including histamine, proteases, and cytokines. These mediators are often stored within cytoplasmic granules in MCs and may be released in a granulated form. The secretion of cytokines and chemokines occurs within hours following activation, with the potential to result in chronic inflammation.

Disruption of cholinesterases and, as a consequence, increased levels of acetylcholine lead to serious disturbances in the functioning of the nervous system, including death. The need for rapid administration of an antidote to restore esterase activity is critical, but practical implementation of this is often difficult. One promising solution may be the development of antidote delivery systems that will release the drug only when acetylcholine levels are elevated.

Background: Patients with hematological malignancies are at high-risk of Clostridium difficile infection (CDI). Oral vancomycin is a first-line treatment for CDI. Vancomycin has been widely reported to induce flushing syndrome (also known as Red man syndrome), a well-known hypersensitivity reaction mostly occurs after intravenous administration.

Atopic dermatitis (AD) is a multifaceted inflammatory skin condition characterized by the involvement of various cell types, such as keratinocytes, macrophages, neutrophils, and mast cells. Research indicates that flavonoids possess anti-inflammatory properties that may be beneficial in the management of AD. However, the investigation of the glycoside forms for anti-AD therapy is limited.
