Comparing the Cosmetic Effects of Liquid-Fermented Culture of Some Medicinal Mushrooms Including Antioxidant, Moisturizing, and Whitening Activities.

There have been few studies on the cosmetic efficacy of Coprinus comatus, Cordyceps militaris, and Pleurotus geesteranus. This article aims to compare the cosmetic effects of the mycelium, fermentation broth, and mycelium and fermentation broth mixture of liquid-fermented C. comatus, C. militaris, and P. geesteranus. Our results verified that these three edible mushrooms all showed excellent antioxidant, moisturizing, and whitening effects. Comparatively, we found that the cosmetic effects of C. comatus were superior to C. militaris and P. geesteranus. Therefore, we speculate that among the three edible mushrooms, C. comatus will be the most suitable to be used as a basis for cosmeceutical formulations to tackle skin aging and hyperpigmentation. This research aims to provide a basis for the study of the cosmetic effects of edible mushrooms.

The Shaggy Ink Cap Medicinal Mushroom, Coprinus comatus (Agaricomycetes), a Versatile Functional Species: A Review.

Coprinus comatus, an edible and medicinal mushroom, not only tastes delicious, but also has various pharmacological activities. Recently, it has been reported that researchers have extracted more and more active ingredients, including polysaccharides, comatin, active protein complexes, and phenols from fruit bodies, mycelium, or fermentation liquor of C. comatus and studied their corresponding functions. At present, researchers mainly focus on the hypoglycemic effect of C. comatus, while other effects are less studied. This paper summarizes not only the hypoglycemic effect of C. comatus, but also other functions, such as antioxidant activity, alcohol liver protection, cancer inhibition, antiandrogenic function, anti-inflammatory effect, treatment of leukemia, and so on, which will provide scientific basis for the deep processing and comprehensive utilization of C. comatus.

Combined toxicity and detoxification of lead, cadmium and arsenic in Solanum nigrum L.

A 3-factor-5-level central composite design was conducted to investigate the combined toxicity and detoxification mechanisms of lead (Pb), cadmium (Cd) and arsenic (As) in Solanum nigrum L. The three metal(loid)s exhibited low-dose stimulation and high-dose inhibition on plant length. Analyses of eleven oxidative stress and antioxidant parameters showed all Pb, Cd and As induced oxidative damages, and the co-exposure further enhanced their toxic effects. Pb, Cd and As were mainly accumulated in plant roots and poorly translocated to shoots, being beneficial for metal(loid) detoxification. The results of subcellular fractionation showed that Pb, Cd and As in plant leaves, stems and roots were mainly localized in the cell wall and soluble fractions. Most of Pb and As in soils occurred in residual fraction while Cd in exchangeable fraction. Although single Pb, Cd and As in all plant tissues existed predominantly in 1 M NaCl-soluble form, the d-H2O and 80 % ethanol-soluble forms were increased under the binary or ternary combinations. This study will conduce to the potential use of S. nigrum L. in the phytostablization of soil co-contaminated with Pb, Cd and As.

Study on the Effect of Ginsenosides Rb on Blood of Tumor Mice.

OBJECTIVE: The blood of cancer patients is in a state of hypercoagulability, easily leading to thrombosis. Anemia is also a complication of tumors. Anemia and thrombosis affect the treatment of tumor patients. METHODS: Ginsenosides Rb were extracted from the stems and leaves of American ginseng using water-saturated ethanol and ethyl acetate in silica gel column. Tumor mice model was established by injecting H22 hepatocellular carcinoma cells into the axilla of mice. Mice were randomly divided into 6 groups: normal control group, model control group, positive control group, low dose group (7 mg/kg), middle dose group (14 mg/kg), and high dose group (35 mg/kg). After 18 days, the blood was obtained by picking the eyeball of mice. The levels of red blood cells (RBC), hemoglobin (HGB), neutrophils/lymphocytes radio (NLR), platelets (PLT), platelet distribution width (PDW), fibrinogen (FIB), and D-Dimer (D-D) were measured and compared in each group of mice. RESULTS: The content of obtained ginsenosides Rb reached 90.05%. This extraction process was simple and reliable. Middle dose of ginsenosides Rb could significantly increase RBC and HGB levels (P<0.05). Moreover, ginsenosides Rb could significantly reduce NLR, PLT, PDW, FIB, and D-D (P<0.01). CONCLUSION: ginsenosides Rb could significantly improve anaemia and hypercoagulation of blood in cancer mice. Ginsenosides Rb are a potential anticoagulant and antianemia drug in treating cancer.

Silymarin's Inhibition and Treatment Effects for Alzheimer's Disease.

As a longstanding problem, Alzheimer's disease (AD) has stymied researchers in the medical field with its increasing incidence and enormous treatment difficulty. Silymarin has always been valued by researchers for its good efficacy and safety in treating liver disease. Recent studies have shown that silymarin also has good pharmacological activity in the nervous system, especially for the treatment of AD. Silymarin can control the production of Aß by inhibiting the precursor substance of Aß (ß-amyloid precursor protein), and it can inhibit the polymerization of Aß. Silymarin can also increase the acetylcholine content in the nervous system by inhibiting cholinesterase activity. At the same time, it also has the effect of resisting oxidative stress and the inflammatory response of the nervous system. These pharmacological activities contribute to the inhibition of the onset of AD. The good efficacy of silymarin on AD and its high safety and availability give it huge potential for the treatment of AD.

Effects of short-term invasion of Spartina alterniflora and the subsequent restoration of native mangroves on the soil organic carbon, nitrogen and phosphorus stock.

The exotic cordgrass Spartina alterniflora has severely invaded the mangrove wetlands in southern China and ecological restoration using native mangroves was conducted in an attempt to control this invasive species. In this study, the contents and pools of soil organic carbon (SOC), total nitrogen (TN) and total phosphorus (TP) were quantified to investigate the invasive effects of S. alterniflora and then to evaluate whether the ecological restoration of native mangrove could reverse those effects. S. alterniflora only showed significantly higher organic carbon content in the surface 0-10 cm of soil than in the uninvaded mudflat. The high δ13C values in the surface soil of the invaded habitat demonstrated that S. alterniflora contributed 42.6-62.2% of the organic carbon. The SOC for invasive S. alterniflora and newly restored mangroves (4 years and 14 years) was not enhanced in comparison to the unvegetated mudflat. S. alterniflora significantly increased the surface soil TN content, but decreased the available phosphorus content and TP density. The TN densities increased gradually with the mangrove restoration, while the TP densities were only slightly influenced. The results suggested that short-term invasion of S. alterniflora and subsequent mangrove restoration did not alter SOC or TN pool sizes, but S. alterniflora was shown to affect the potential carbon storage capacity produced by the mangroves in the Zhangjiang Estuary.

Study on Transformation of Ginsenosides in Different Methods.

Ginseng is a traditional Chinese medicine and has the extensive pharmacological activity. Ginsenosides are the major constituent in ginseng and have the unique biological activity and medicinal value. Ginsenosides have the good effects on antitumor, anti-inflammatory, antioxidative and inhibition of the cell apoptosis. Studies have showed that the major ginsenosides could be converted into rare ginsenosides, which played a significant role in exerting pharmacological activity. However, the contents of some rare ginsenosides are very little. So it is very important to find the effective way to translate the main ginsenosides to rare ginsenosides. In order to provide the theoretical foundation for the transformation of ginsenoside in vitro, in this paper, many methods of the transformation of ginsenoside were summarized, mainly including physical methods, chemical methods, and biotransformation methods.
