Chemical characterization and encapsulation of extract with cytotoxic properties.

Mushrooms of the genus are known for diverse biological activities, demonstrated both traditionally and experimentally. Their secondary metabolites have shown cytotoxic potential across different cancer cell lines. Besides exploration of the most active components in different species or genotypes, new formulation techniques are in development.

Mid-Infrared Spectroscopic Study of Cultivating Medicinal Fungi : Composition, Development, and Strain Variability of Basidiocarps.

Attenuated total reflection Fourier-transform infrared (ATR-FTIR) spectroscopy was proposed for rapid, versatile, and non-invasive screening of basidiocarps to assess their potential for specific applications. Fifteen species and strains of this fungus were selected for analysis, and fine sections at different parts of young and mature basidiocarps were obtained. The spectra of fungal samples showed significant differences interpreted in terms of biochemical composition using characteristic bands of proteins, polysaccharides, lipids, and triterpenoids.

Antioxidant and Anti-Inflammatory Activity of Five Medicinal Mushrooms of the Genus .

Within the group of higher fungi, edible medicinal mushrooms have a long history of being used as food and in folk medicine. These species contain biologically active substances with many potential beneficial effects on human health. The genus is representative of medicinal mushrooms because is one of the most commonly cultivated culinary mushrooms.

Polysaccharides from Basidiocarps of the Polypore Fungus : Isolation and Structure.

In this study, we focused on the isolation and structural characterization of polysaccharides from a basidiocarp of polypore fungus . Polysaccharide fractions were obtained by successive extractions with cold water at room temperature (20 °C), hot water under reflux (100 °C), and a solution of 1 mol L sodium hydroxide. The purity of all fractions was controlled mainly by Fourier transform infrared (FTIR) spectroscopy, and their composition and structure were characterized by organic elemental analysis; neutral sugar and methylation analyses by gas chromatography equipped with flame ionization detector (GC/FID) and mass spectrometry detector (GC/MS), respectively; and by correlation nuclear magnetic resonance (NMR) spectroscopy.

Polysaccharides from Basidiocarps of Cultivating Mushroom : Isolation and Structural Characterization.

Oyster mushrooms are an interesting source of biologically active glucans and other polysaccharides. This work is devoted to the isolation and structural characterization of polysaccharides from basidiocarps of the cultivated oyster mushroom, . Five polysaccharidic fractions were obtained by subsequent extraction with cold water, hot water and two subsequent extractions with 1 m sodium hydroxide.

Cultivation of Medicinal Mushrooms on Spruce Sawdust Fermented with a Liquid Digestate from Biogas Stations.

The aim of this work was to prepare a softwood substrate on which to grow edible and medicinal mushrooms. Liquid digestate from a biogas station was successfully used in spruce sawdust fermentation. Pleurotus ostreatus, P.

Comparing the removal of polycyclic aromatic hydrocarbons in soil after different bioremediation approaches in relationto the extracellular enzyme activities.

A 120-day experiment was conducted to compare the removal of polycyclic aromatic hydrocarbons (PAHs) from agricultural soil after natural attenuation (NA), phytoremediation (P), mycoremediation (M), and plant-assisted mycoremediation (PAM) approaches in relation to the extracellular enzyme activities in soil. The NA treatment removed the total soil PAH content negligibly. The P treatment using maize (Zea mays) enhanced only the removal of low and medium molecular PAHs.

[Angiodysplasia--a cause of severe hemorrhage in the gastrointestinal tract].

The authors describe a case of relapsing severe haemorrhage from angiodysplasias localized in the small intestine in an eighty-year-old female patient diagnosed only after probatory laparotomy. They discuss the diagnostic possibilities in angiodysplasia of the gastrointestinal tract and how it can be influenced by therapy. Even after resection of the affected portion of the intestine the formation of new angiodysplasias must be foreseen in previously intact areas and those can be the source of further severe haemorrhage.

[Initial experience with thin-needle biopsy under ultrasonic control in diffuse liver diseases].

The authors used thin-needle biopsy (Westcott needle) under ultrasonographic control for the morphological determination of ultrasonographic pictures of steatosis in 37 patients. In the case history they reported alcohol consumption of more than 5 years above 60 g of absolute alcohol per day; mostly abuse of beer was involved (32.4%) and beer with liquor (43.

[Non-cystic diseases of the liver in a 5-year ultrasonographic study].

The authors evaluate five-year ultrasonographic material (13,672 examinations) focused on non-cystic liver disease. 8212 examinations (60.1%) were made as part of examinations of the gallbladder, 4919 (36%) as part of examination of the right sub-costal area or other organs and only 541 examinations (3.

[Cystic changes in the liver in our 5-year ultrasonographic study].

The authors examined during 1983-1987 by ultrasonography the liver in a group of 13,672 patients with an average age of 54.8 +/- 4.1 years.

[Results of treatment of peptic ulcers using Gastrozepine and antacids in the endoscopic picture].

The authors investigated the therapeutic results in gastroduodenal ulcers in 96 patients treated with Gastrozepin (Slovakofarma), using daily doses of 75 mg combined with antacids. The examinations were made by means of a videogastroscope of Welch-Allyn Co. with subsequent control after four weeks, and if the ulcer was not healed, after two-week intervals.
