controls. An endoscopy study was performed showing contractions on the medium and distal third of oesophagus like a bamboo joint and the histological study showed up to nine eosinophils in the oesophageal mucosa. Although clinical symptoms and macroscopic images from the endoscopic study suggested an eosinophilic oesophagitis, the number of eosinophils was not diagnostic. However, some authors ...
Tyrosinase is a key enzyme in melanin production. Therefore, tyrosinase inhibitors are used in cosmetic and medicinal industries to prevent or treat overproduction of melanin such as melasma, solar lentigo and post inflammatory melanoderma. Due to safety of natural whitening agents, in the present study, in-vitro anti-tyrosinase and in-vivo anti-melanogenesis activities of some selected red mac...
OBJECTIVES In previous studies, antioxidant activity of Viola odorata L. has been demonstrated. In this study, we have investigated the anti-melanogenic effect of extract and fractions of the plant in B16F10 cell line. MATERIALS AND METHODS Impact of different increasing concentrations of extract and fractions of V. odorata was evaluated on cell viability, cellular tyrosinase, melanin content...
The antioxidant and anti-inflammatory activities of various solvent extracts of Fomitopsis dochmius, a polypore found in Western Ghats of Kerala, India were investigated. Petroleum ether (PE), ethyl acetate (EA), 70 % aqueous ethanol (ETH) and hot water (AQ) extracts of the fruiting bodies of the mushroom were examined for their antioxidant activities. PE was found to show activity against hydr...
Lentinus lepideus is an edible mushroom currently available in Korea. The acetone, methanol and hot water extracts were prepared and assayed for their antioxidant and antityrosinase inhibitory activities. The hot water extract showed the strongest β-carotene-linoleic acid inhibition compared to the other extracts. At 8 mg/mL, the methanolic extract showed a high reducing power of 1.21. The acet...
Cellular damage caused by reactive oxygen species has been implicated in several diseases and hence antioxidants have significant importance in human health. Cold water, hot water and methanolic extract of Pleurotus squarrosulus were evaluated for antioxidant activity against hydroxyl radical, DPPH (1,1-Diphenyl-2-picrylhydrazyl) radical, superoxide radical, nitric oxide (NO) scavenging, reduci...
This study was conducted in order to perform efficient extraction of lignocellulolytic enzymes amylase (EC 3.2.1.1), cellulase (EC 3.2.1.4), laccase (EC 1.10.3.2), and xylanase (EC 3.2.1.8) from spent mushroom compost (SMC) of Pleurotus ostreatus, P. eryngii, and P. cornucopiae. Optimal enzyme recovery was achieved when SMCs were extracted with 50 mM sodium citrate (pH 4.5) buffer at 4℃ for 2 h...
Pleurotus florida has been widely used for nutritional and medicinal purposes. The present study was conducted to evaluate the antioxidant and anti-inflammatory effects of the fruiting bodies of P. florida extracted with acetone, methanol, and hot water. The antioxidant activities of the acetone and methanol extracts of P. florida showed stronger inhibition of β-carotene-linoleic acid compared ...
