Pharmacological activity cream of extract Salix alba and zinc for allergic contact dermatitis
Abstract
Allergic dermatitis is the most common skin disease, manifested by classic factors in response to the external environment. Solving the problem of global prevalence and intensive growth of the frequency of allergic dermatitis requires improving the medical supply of the population of Ukraine with drugs for the effective treatment of allergic skin diseases. According to the literature, preparations based on white willow bark have a wide range of biological effects, which exhibit anti-inflammatory, anti-allergic, anti-pruritic, analgesic activity and have a positive effect on the immune system and are promising for the treatment and prevention of allergic dermatitis. Zinc takes part in metabolism and stabilization of cell membranes, is part of the main enzymes that take part in antioxidant biochemical reactions. The trace element has a regenerating effect, ensures the transmission of nerve impulses, promotes the synthesis of cortisol. The purpose of our work was to study the effect of a cream based on white willow and Zn antigen-specific link of immune protection of animals on 3 experimental allergic dermatitis. The study was conducted on сavia porcellus. Allergic contact dermatitis was modeled using 2,4-dinitrochlorobenzene. Phagocytic activity of granulocytic neutrophils in a suspension of leukocytes is determined for assessment of the activity of factors of non-specific immunity. It is important to determine the status of antigen-specific factors of immune protection, which are directly involved in all doses of the immune response. To assess the activity of factors of nonspecific immunity, the phagocytic activity of granulocytic neutrophils was determined in the suspension of leukocytes obtained from heparinized blood. The obtained data on the increase of F1 and F4 indicators in animals against the background of experimental dermatitis indicate the presence of a natural protective defense aimed at neutralizing the allergen and its subsequent removal from the body. In comparison with reference drugs it was found distinct antigen-specific effect, which exceeds Psoricap and is equal Fladex. On the model of allergic contact dermatitis in Cavia porcellus, the researched cream showed a pronounced immunotropic activity relative to a decrease in the phagocytic activity of cell.
