toxicodendron radicans/inflammation

We have studied Microciona prolifera cells as a model for inflammation and secretion. Dissociated in Ca-, Mg-free seawater with 2.5 mM EDTA, the cells aggregate when exposed to Ca (greater than 5 mM) and Ca ionophores. Extracellular Ca is not required over the course of aggregation; brief pulses of

Typical manifestations of cutaneous inflammation include erythema and edema. While erythema is the result of capillary dilation and local increase of oxygenated hemoglobin concentration, edema is characterized by an increase in extracellular fluid in the dermis, leading to local tissue swelling.

BACKGROUND Leaves of Plantago erosa ex Roxb are used traditionally in Northeast India in different illnesses which include wounds, cuts, bruises, insect bites, poison-ivy rashes, minor sores and snakebite, etc. OBJECTIVE Plantago erosa is one of the commonly used medicinal plants in various

In 1986 it was discovered that cultured human keratinocytes, when treated with gamma interferon, attract and bind T lymphocytes and monocytes. More is now known about trafficking of inflammatory cells in the skin, with specific molecular details involving various cytokines, chemotactic factors, and

In our preliminary screening study on the anti-inflammatory activity, eight triterpenes, one sterol, and one chalcone were isolated from the CH(2)Cl(2)-soluble extract of the stems and leaves of Rhus sylvestris Siebold and Zucc (Anacardiaceae). On the basis of their spectroscopic data, these

Despite the availability of multiple therapeutic agents, the search for novel pain management of neuropathic pain is still a challenge. Oxidative stress and inflammatory signaling are prominently involved in clinical manifestation of neuropathic pain. Toxicodendron pubescens, popularly known as Rhus

CD1a is a lipid-presenting molecule that is abundantly expressed on Langerhans cells. However, the in vivo role of CD1a has remained unclear, principally because CD1a is lacking in mice. Through the use of mice with transgenic expression of CD1a, we found that the plant-derived lipid urushiol

Allergic contact dermatitis is a common skin disease associated with inflammation and persistent pruritus. Transient receptor potential (TRP) ion channels in skin-innervating sensory neurons mediate acute inflammatory and pruritic responses following exogenous stimulation and may contribute to

Allergic contact dermatitis was elicited with Toxicodendron antigen and the patch test site examined at various time intervals up to one week. The degree of inflammation was rather constant during the observation period. The mean erythema score at 168 hours was not significantly different from the

BACKGROUND Homeopathic Rhus toxicodendron (Rhus tox) is used in various inflammatory conditions. We screened its effect compared to succussed ethanol controls and appropriate active controls. METHODS We initially experimented with Rhus tox 6, 12, 30 and 200 cH, using carrageenan-induced paw oedema

BACKGROUND Homeopathic remedy Rhus toxicodendron (Rhus tox) is used for several symptoms including skin irritations, rheumatic pains, mucous membrane afflictions, and typhoid type fever. Previously, we reported that Rhus tox treatment increased the cyclooxygenase-2 (COX-2) mRNA expression in primary

BACKGROUND Toxicodendron vernicifluum (Stokes) F.A. Barkley (Anacardiaceae) has traditionally been used as a food supplement and in traditional herbal medicine to treat inflammatory diseases and cancers for centuries in Korea. This study was designed to isolate the bioactive constituents from the

BACKGROUND Toxicodendron pubescens is a botanical name of Rhus toxicodendron (Rhus tox). This plant is widely used in its homeopathically diluted form in the treatment of inflammatory and edematous conditions. In this study, various dilutions of Rhus tox including its crude form have been evaluated
