This literature review provides an up-to-date exploration of the multifaceted attributes of maitake mushrooms (Grifola frondosa), elucidating their bioactive phytochemicals and diverse health advantages, including their substantial role in supporting human health and potential incorporation into the medicinal industry. Carbohydrates and protein are the major constituents contributing to the dry weight of G. frondosa, taking up around 70–80 % and 13–21 %, respectively, with emerging research linking these constituents to various health benefits. By synthesising current research findings, this review emphasises the substantial role of maitake mushrooms in supporting human health and underscores their potential incorporation into the medicinal industry. To further advance our understanding, future research should delve into the mechanisms underlying their health-promoting effects, with a focus on conducting quantitative studies to elucidate physiological pathways and potential drug interactions. Additionally, exploring their integration into functional foods or nutraceuticals through quantitative assessments of bioavailability and efficacy will be crucial for maximising their therapeutic benefits. This review aims to provide comprehensive insights, catalysing further research and innovation in utilising maitake mushrooms for improved well-being and industry advancement.

Colorectal cancer is a dangerous oncological disease that requires serious complex treatment. This type of oncopathology occurs due to atypical growth of the epithelium of the mucous layer that lines the intestinal walls. Colon cancer is characterized by slow development, so prevention and timely diagnosis are a priority. The main advantage of using oncoprotectors based on natural raw materials in clinical practice is their low toxicity and the possibility of long-term use without significant side effects. That is why the development and study of such drugs are relevant. The aim of the research was to study indicators of oxidative processes and antioxidant systems in rats with chemically induced colon carcinogenesis against the background of maitake mushrooms thick extract use. The study was performed on 120 white male rats weighing 190–210 g. Adenocarcinoma of the colon was modeled by administering 1,2-dimethylhydrazine (DMH) hydrochloride for 30 weeks (1 time per week). A thick extract from maitake mushrooms was administered intragastrically daily at a dose of 150 mg/kg of animal body weight. Blood and liver samples were taken for research monthly. The state of the pro- and antioxidant systems was studied by the content of oxidative modification of proteins products neutral and alkaline character, superoxide dismutase and catalase activity, contents of reduced glutathione and ceruloplasmin. It was found that DMH-induced colon carcinogenesis in rats is accompanied by an increase in the activity of free radical oxidation processes. It is evidenced by a decrease in superoxide dismutase activity, catalase activity, a significant reduction in the content of reduced glutathione, an increase in the content of ceruloplasmin and products of oxidative modification of proteins in the blood serum and liver of animals. The effectiveness of maitake mushrooms thick extract and its positive influence on the activity of the studied enzymes and the content of OMP products in investigated tissues was experimentally proved. The use of maitake mushrooms thick extract under conditions of DMH-induced colon carcinogenesis in rats led to the normalization of antioxidant protection indicators and a significant decrease in the indicators of oxidative modification of proteins, which testifies to the suppression of oxidative stress in animals with an oncological process.

Background. The priority of the contemporary pharmaceutical industry is to create effective, safe and inexpensive drugs to ensure the highest quality of care and optimal use of available raw materials. Objective. The aim of our study was to investigate anti-inflammatory properties of the Maitake mushrooms thick extract in the experiment on rats with paracetamol(acetaminophen)-induced hepatitis. Methods. 60 white male rats, weighing 180-210 g, randomized into 10 groups of 6 animals in each, were used for the experiment. Paracetamol hepatitis was simulated by acetaminophen intragastric administering in a dose of 1250 mg/kg 1 time per day (for 2 days) as a suspension in 2% starch gel solution. Maitake mushrooms thick extract, which was administered intragastrically 2 hours before the administration of acetaminophen and daily after the lesion in a dose of 150 mg/kg of the animal’s body weight, was used for the toxic lesion correction. “Silibor” was selected as the comparison drug, which was administered according to the same scheme as the investigated extract in a dose of 20 mg/kg of the animal’s body weight. Euthanasia was conducted on the 3rd, 7th and 10th day of the experiment with sodium barbamyl. Liver homogenate and animal serum were used for the studies. The development of inflammatory processes was studied by the content of pro-inflammatory and anti-inflammatory cytokines, as well as C-reactive protein in the serum of rats with toxic hepatitis and after the application of Maitake mushroom extract and the comparison drug. Results. It was found that the introduction of acetaminophen to animals for the acute hepatitis simulation is accompanied by changes in the cytokine profile, i.e. an increase in the level of IL-6 and a decrease in the level of IL-4 in the serum of rats. Inflammatory development is evidenced by the content of C-reactive protein increase in the blood of the affected animals. The application of Maitake mushroom extract facilitated bringing the studied indicators almost to the level of intact control. Conclusions. Reduction of inflammation signs in rats with the simulated paracetamol hepatitis under the influence of Maitake mushrooms thick extract confirms its anti-inflammatory properties. Objective.

The application of the Maitake mushrooms thick extract as a corrective factor at the simulated paracetamol hepatitis confirms its anti-inflammatory properties.

It is known that the violation of one or more functions of the liver, where the basic biochemical processes take place, is reflected in the functional state of many organs and systems, causing severe consequences. For the effective treatment of the hepatobiliary system diseases the drugs from fungi and plant materials are promising, the ingredients of which are close to natural metabolites, have different mechanisms of hepatoprotective action and, in general, can have a positive effect on liver function., Aim: The aim of the research was to investigate the hepatoprotective properties of the Maitake mushrooms thick extract in the experiment on rats with paracetamol (acetaminophen)-induced hepatitis., Materials and Methods: The study was performed on 60 white male rats weighing 180-210 g and aged 6-6,5 months. Rats were divided into 10 groups, each of which included 6 animals. Acute hepatitis was simulated by acetaminophen intragastrically administering at a dose of 1250 mg/ kg of body weight 1 time per day as a suspension in 2% starch gel solution for 2 days. Correction of the toxic lesions was performed with a thick extract of Maitake mushrooms, which was administered intragastrically 2 hours before the introduction of acetaminophen and daily after the lesion at a dose of 150 mg/kg of body weight. "Silibor" (active basis - silymarin) was chosen as a comparison drug, which was administered according to the same scheme as Maitake extract at a dose of 20 mg/kg of animal body weight. On the 3rd, 7th and 10th days from the onset of the lesion, rats were euthanized using sodium barbamyl. Liver homogenate and blood serum were tested. Blood was taken from the hearts of animals. Endogenous intoxication of animals after the introduction of corrective factors was assessed by the activity of ALT, AST, GGTP, LF and the size of the thymol sample. All changes were confirmed by parametric and nonparametric methods of statistical analysis of the results of the study., Results: The expressed cytolysis of hepatocytes, after administration to rats of toxicant, on the basis of research of the activity of aminotransferases, gamma-glutamyltranspeptidase, alkaline phosphatase and thymol sample size is proved. The results of the experiment were confirmed histologically. The introduction of a thick extract of Maitake mushrooms contributed to the normalization of the studied indicators., Conclusions: The application of the Maitake mushrooms thick extract as a corrective factor in the simulated acetaminophen hepatitis indicates its hepato-, cytoprotective and antioxidative properties., (© 2021 MEDPRESS.)
