Inhalation of cotton mill dust or condensed tannin, a major botanical component of cotton mill dust, induces an acute pulmonary inflammatory response characterized by a rapid influx of neutrophils into the airways. The development of neutrophil alveolitis caused by tannin inhalation is accompanied
Inhalation of cotton mill dust leads to the development of the occupational lung disease byssinosis in a portion of the exposed workers. Condensed tannins present in the dust have biologic activities consistent with the hypothesis that they are one of the etiologic agents for the disease. Inhalation
Twelve hydrolyzable tannins were obtained from the twigs of Myricaria bracteata, including two new hellinoyl-type dimers, bracteatinins D1 (1) and D2 (2); a new hellinoyl-type trimer, bracteatinin T1 (3); two known monomers, nilotinin M4 (4) and
Anesthetized, intubated, and mechanically ventilated rabbits were exposed to aerosolized saline, cotton dust extract (CDE), or tannin for 5 minutes and lavaged 4 hours after exposure. Cell numbers and types present in the bronchoalveolar lavage fluid (BALF) were determined and the concentrations of
A study was conducted to evaluate the effects of chestnut tannins (CT) on intestinal morphology, barrier function, pro-inflammatory cytokine expression, microflora and antioxidant capacity in heat-stressed broilers. Four hundred 28-day-old male Ross 308 broilers were randomly assigned into four
The present study was to investigate whether high molecular weight persimmon tannin (HMWPT) is the main component associated with the anti-hyperlipidemic effect of consuming persimmon and its underlying mechanism. Male wistar rats were given a basic diet (control), a high-fat diet, a high-fat diet
In the present study we chemically profiled tannin-enriched extracts from strawberries and tested their biological properties in a cell model of gastric inflammation. The chemical and biological features of strawberry tannins after in vitro simulated gastric digestion were investigated as well. The
A mixture of tannins (hydrolysable and non-hydrolysable) obtained from the bark of Anacardium occidentale L., on i.p. injection, demonstrated apparent anti-inflammatory activity in carrageenan- and dextran-induced rat paw oedemas, cotton pellet granuloma test and adjuvant-induced polyarthritis in
Herbal medicines are important in treatment of inflammation as they are safe and nontoxic. Tannins are important bioactive compounds used as anti-inflammatory agents and possess wound healing potential. Anti-inflammatory activity of tannins extracted from seedling leaf tissue and callus culture
OBJECTIVE
Although consumption of dietary supplements containing pomegranate extract (POMx) by patients with arthritis is on the rise, the efficacy of such preparations in suppressing joint inflammation and damage is not known. The present study was designed to evaluate a standardized preparation of
Penta-O-galloyl-β-d-glucose (PGG) was purified and identified from Radix Paeoniae Alba by HSCCC and HPLC/ESI-MS, and its inhibitory effects on adipogenesis and TNF-α-induced inflammation were assessed in 3T3-L1 cell line. The results showed that PGG dose-dependently reduced intracellular lipids
Nontuberculous mycobacteria (NTM), including Mycobacterium avium complex (MAC), cause opportunistic chronic pulmonary infections. Notably, MAC susceptibility is regulated by various factors, including the host immune system. Persimmon (Ebenaceae Diospyros kaki Thunb.) tannin is a condensed tannin
BACKGROUND
The aim of the study was to examine extracts from twelve tannin-rich plant materials used in traditional Polish medicine for external treatment of skin and mucosa diseases considering their ability to inhibit hyaluronidase activity and elastase release from stimulated neutrophils in
