Detection of the cause of dietetic ileus is often difficult. High quality computed tomography (CT) scanning has improved our ability to precisely diagnose a large variety of intra-abdominal and intraluminal disease processes, including the presence of foreign bodies [1]. Here we report a case of ileus caused by ingestion of shiitake mushroom that could be diagnosed before treatment and could be...

Breast cancer is the most commonly diagnosed cancer among women in Western countries. Currently, there is no effective therapy for malignant estrogen-independent breast cancer. We have screened 38 species of edible mushroom on human estrogen-receptor positive (MCF-7) and estrogenreceptor negative (MDA-MB-231, BT-20) breast cancer cells to select potential agents with broad-spectrum antitumor ac...

This study reports depigmenting potency of 1,3-selenazol-4-one derivatives, which would be based upon the finding of direct inhibition to mushroom tyrosinase. 1,3-Selenazol-4-one derivatives exhibited inhibitory effect on dopa oxidase activity of mushroom tyrosinase. In this study, inhibitory effects of six kinds of 1,3-selenazol-4-one derivatives (A, B, C, D, E and F) on mushroom tyrosinase we...

Medicinal and edible mushrooms have been widely used for centuries as nutraceuticals to improve health and to treat numerous diseases. Several species of mushrooms such as Lentinula edodes, Schizophyllum commune, Ganoderma lucidum and Coriolus versicolor have been used as immunostimulators and anticancer agents. Mushroom polysaccharides, as the main active ingredient in the mushroom, belong to ...

In most heterothallic mushroom species, inbreeding is avoided by an incompatibility system determined by two loci each with multiple alleles (the A and B mating-type loci). In this study we investigated the genetic structure of the mating-type loci in the tropical oyster mushroom Pleurotus djamor using both positional cloning and degenerate PCR methods. DNA sequences from genomic regions cosegr...

The present study showed that oral mushroom beta-glucan treatment significantly increased IFN-γ mRNA expression but significantly reduced COX-2 mRNA expression within the lung. For LLC tumor model, oral Ganoderma lucidum or Antrodia camphorata polysaccharides treatments significantly reduced TGF-β production in serum. In addition, IL-12 and IFN-γ mRNA expression were significantly increased, bu...

Cultivation of Pleurotus ostreatus on different substrates such as rice straw, rice straw + wheat straw, rice straw+ paper, sugarcane bagasse and sawdust of alder was investigated. All the substrates except rice straw were supplemented with 10% rice bran. The substrate without supplement was considered as control. The effects of various substrates on mycelial growth, colonization time, primordi...

INTRODUCTION Toxic mushrooms are distributed across the globe with over 5000 species. Among them, 100 species are responsible for most of the cases of mushroom poisoning. This study aimed to evaluate the epidemiologic pattern of mushroom poisoning among patients referred to the main toxicology center of Mashhad province located in North-east of Iran. METHOD This cross-sectional study was cond...

Amanita pantherina poisoning is suspected as the cause of a severe, transient neurological disorder in three 5-week-old German shepherd puppies. There was very strong circumstantial evidence that this mushroom had been eaten, and the signs encountered were similar to those described in confirmed field cases of intoxication in dogs. It was also in many respects consistent with the syndrome seen ...

The fruiting body of Inonotus obliquus, a medicinal mushroom called chaga, has been used as a traditional medicine for cancer treatment. Although this mushroom has been known to exhibit potent antioxidant activity, the mechanisms responsible for this activity remain unknown. In our investigation for free radical scavengers from the methanolic extract of this mushroom, inonoblins A (1), B (2), a...
