introduction : pemphigus comprises a group of diseases characterized by cutaneous and mucosal blistering. pemphigus vulgaris (pv) is the most common and important variant. recent reports have revealed the relatively high incidence of pv in iran. the onset or aggravation of many human diseases is attributed to oxidative stress and it has been suggested as one of the several factors responsible f...

results theophylline-treated rats showed mda level elevation and gpx activity reduction. quercetin treatment improved heart conditions and resulted in a significant reduction in mda levels and elevation in gpx activity. moreover, co-administration of quercetin and theophylline increased the heart weight significantly. furthermore, histophatological study showed no changes in the treated groups....

Herein, Cu–HMT and Ni–HMT were synthesized via a green synthetic method. possesses formidable peroxidase-mimic activity compared to Ni–HMT. However, the peroxidase-like of was strongly inhibited in presence DA.

plant materials have been found useful in decontamination of water polluted with phenolic compounds. the detoxification effect is due to peroxidases contained in plant tissue. enzyme mediated oxidative coupling of phenol is followed by precipitation of the formed polymer and its removal from the aqueous phase. a synthetic wastewater buffered at ph = 7.4 containing 0.9 mm phenol was treated in t...

Ethylenediurea (EDU), N[2-(2-oxo-l-imidazolidinyl) ethyl]-N'-phenylurea is known to prevent ozone (03) damage to leaf tissues. However, the mechanisms of protection are unclear. We tested the hypothesis that EDU protects against 03 damage by scavenging hydroxyl free radicals (OH). An in vitro study involving the use of high-performance liquid chromatography equipped with an electrochemical dete...

Phanerochaete chrysosporium BKM-1767 secretes multiple lignin peroxidase isoenzymes when grown under nitrogen-limited conditions. Here we report the purification of these heme-containing peroxidases, and their physical and catalytic charaterization. Ten hemeproteins, designed H1-H10, were separated by anion exchange HPLC. Six of them, H1, H2, H6, H7, H8, and H10, were lignin peroxidases, oxidiz...

BACKGROUND Launaea procumbens (Asteraceae) is used as a folk medicine to treat hepatic disorders in Pakistan. The effect of a chloroform extract of Launaea procumbens (LPCE) was evaluated against carbon-tetrachloride (CCl4)-induced liver damage in rats. METHODS To evaluate the hepatoprotective effects of LPCE, 36 male Sprague-Dawley rats were equally divided into six groups. Animals of group ...

Monoclonal antibodies against prostaglandin H (PGH) synthase have been used to precipitate cyclooxygenase and peroxidase activities from detergent-solubilized preparations of ram seminal vesicle microsomes. Approximately 85% of the solubilized cyclooxygenase activity was precipitated using an excess of anti-PGH synthase antibody; under similar conditions, immunoprecipitation of 60% of the diphe...

After intravenous injection of horseradish peroxidase into rats, the foreign protein appeared in the kidney first in the small phagosomes and its concentration there decreased quickly; it then was concentrated and "stored" for several days in the large phagosomes. After injection of 10 mg of peroxidase per 100 gm of body weight, the concentration of peroxidase in blood and urine decreased expon...
