Abstract

Wheat embryo globulin (WEG) has been proven to possess multiple biological activities, including antioxidative properties, immunomodulatory, and so on. Aged mouse model were established by subcutaneous injection of D-galactose (D-gal), and the effects of WEG on learning, memory, and antioxidant capacity in aging mice were explored through behavioural tests and antioxidant enzyme activities determination. Compared with the Model group, WEG improved the percentage of the platform quadrant, increased the number of crossing platforms, and enhanced the identification indexs. WEG also increased total antioxidant capacity (T-AOC), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) activities in the liver and brains of aging mice, and reduced malondialdehyde (MDA) content. Pathological observations indicated that WEG protected against damage to brain in D-gal-induced aging mice. These results effectively revealed that WEG not only improved the abilities of learning and memory, and the cognitive impairment, but also delayed the aging process of the D-gal-induced mice.

Abstract

Wheat Embryo Globulin (WEG) is a high-quality plant-derived protein with anti-inflammatory, antioxidant, and immunity enhancement effects. WEG was prepared and characterized using free amino acid analysis, circular dichroism (CD), and scanning electron microscope (SEM). The liver protection effect of WEG on mice after acute alcohol stimulation was also investigated. Male KM mice were randomly divided into four groups (n = 10). Animals were orally administrated with WEG (60 mg/kg), silymarin (50 mg/kg), and the same volume of saline solution daily for 30 days, before administering an alcohol-intragastric injection. Results displayed that the liver index, the levels of serum total cholesterol (TC), serum triglyceride (TG), liver malondialdehyde (MDA) and the mRNA expression of CYP2E1were significantly decreased in WEG-treated mice compared with the model group. Meanwhile, the levels of serum high-density lipoprotein-cholesterol (HDL-C), hepatic reduced glutathione (GSH), superoxide dismutase (SOD) and the mRNA expression of ADH2 and ALDH2 were remarkably increased. Effect of WEG on histopathology of liver tissue confirmed its protective function. Meanwhile, GSH level of ileal was significantly increased, MDA was remarkably decreased in WEG-treated mice, which also indicated that WEG possessed a positive effect on intestinal micro ecological environment health to some extent. In conclusion, WEG is a promising agent for the prevention of acute alcoholic liver injury.

Abstract

Sheath blight caused by Rhizoctonia solani is a major disease of rice worldwide. Silicon (Si) can enhance rice resistance to sheath blight, but the relation with phenolic metabolism is poorly known. Two rice cultivars with different levels of resistance to R. solani (resistant Teqing and susceptible Ningjing 1) were studied to determine the effects of Si on disease intensity (rated from 0 to 9) and the involvement of phenolic compounds in disease resistance. Variation in the concentrations of phenolics (including total soluble phenolics, flavonoids, and lignin) and in the activities of defense-related enzymes polyphenoloxidase (PPO) and phenylalanine ammonia-lyase (PAL) in rice leaf sheaths was investigated. The results show that Si application reduced sheath-blight disease ratings of Ningjing 1 and Teqing by 2.96 and 0.65, respectively. In uninoculated plants, Si application alone had no significant effects on the concentrations of phenolic compounds or on the activities of PPO and PAL. In inoculated plants, Si application increased phenolics concentrations and PPO and PAL activities only in the susceptible cultivar Ningjing 1. We conclude that Si-induced enhancement of phenolic metabolism contributed to the improved resistance of rice to sheath blight in the sensitive cultivar.
