Subcellular Distribution and Chemical Forms of Cadmium in the Medicine Food Homology Plant Platycodon grandiflorum(Jacq.)A.DC.

Although Platycodon grandiflorum(Jacq.)A.DC.is a renowned medicine food homology plant,reports of excessive cadmium(Cd)levels are common,which affects its safety for clinical use and food consumption.To enable its Cd levels to be regulated or reduced,it is necessary to first elucidate the mechanism of Cd uptake and accumulation in the plant,in addition to its detoxification mechanisms.This present study used inductively couple plasma-mass-spectrometry to analyze the subcellular distribution and chemical forms of Cd in different tissues of P.grandiflorum.The experimental results showed that Cd was mainly accumulated in the roots[predominantly in the cell wall(50.96%-61.42%)],and it was found primarily in hypomobile and hypotoxic forms.The proportion of Cd in the soluble fraction increased after Cd exposure,and the proportion of insoluble phosphate Cd and oxalate Cd increased in roots and leaves,with a higher increase in oxalate Cd.Therefore,it is likely that root retention mechanisms,cell wall deposition,vacuole sequestration,and the formation of low mobility and low toxicity forms are tolerance strategies for Cd detoxification used by P.grandiflorum.The results of this study provide a theoretical grounding for the study of Cd accumulation and detoxification mechanisms in P.grandiflorum,and they can be used as a reference for developing Cd limits and standards for other medicine food homology plants.

The Protective Effect of Jiujiuguiyi, a Medicine and Food Homologous Formula, on Acute Alcohol Poisoning Mice

Background: Nowadays, acute alcoholic intoxication has become the third public problem in China, and the anti-inebriation products mainly aimed at increasing the activity of enzyme involved in the alcohol metabolism, which is a single mechanism that can accelerate alcohol metabolism. Thus, a new formula, Jiujiuguiyi (JJGY) which could protect liver, relieve the abnormal excitability of the center and improve muscle retardation at the same time is designed by us. Methods: The model of acute alcoholic intoxication was established by intragastric administration with 0.12 ml/10g 50% alcohol in mice. JJGY was orally administrated (gavage) once a day for 20 consecutive days before the establishment of acute alcoholic model. Mice were randomly divided into 8 groups with 8 each: blank control group (CON), model group (M), Haiwangjinzun positive control group (HWJZ), experimental groups (AL, AH, BL, BH, AB). Giant, crawling time on the rota-rod, the activities of aspartate amino trans- ferase (AST), alanine amino transferase (ALT) and superoxide dismutase (SOD) in both liver and serum, alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH), glutathione peroxidase (GSH-PX) in liver as well as the HE staining of liver slices, the formation of malondialdehyde (MDA) in serum were determined after acute alcoholic intoxication. Results: Compared with model group, JJGY significantly decreased the AST and ALT activity in liver and serum and MDA activity in serum. Meanwhile, it enhanced the ADH and ALDH level in liver as well as the hepatic and serous SOD activity, indicating more efficient metabolism of alcohol and less hepatic injury. HE staining results also proved that JJGY could reduce alcoholic liver cell injury, and the effect was more obvious in the group medicated before alcohol administration. Moreover, JJGY significantly prolonged the crawling time on the rota-rod and improved the gait of mice and the effect was proved to be better than the widely used health product Haiwangjinzun. Conclusions: This study suggests that JJGY is able to protect liver, relieve the abnormal excitability of the center and improve muscle retardation after acute alcoholic intoxication. Its liver protection effect is likely related to its modulation on the alcohol metabolizing and antioxidant enzymes.

Research progress of ginger in the treatment of gastrointestinal tumors

Cancer seriously endangers human health.Gastrointestinal cancer is the most common and major malignant tumor,and its morbidity and mortality are gradually increasing.Although there are effective treatments such as radio-therapy and chemotherapy for gastrointestinal tumors,they are often accom-panied by serious side effects.According to the traditional Chinese medicine and food homology theory,many materials are both food and medicine.Moreover,food is just as capable of preventing and treating diseases as medicine.Medicine and food homologous herbs not only have excellent pharmacological effects and activities but also have few side effects.As a typical medicinal herb with both medicinal and edible uses,some components of ginger have been shown to have good efficacy and safety against cancer.A mass of evidence has also shown that ginger has anti-tumor effects on digestive tract cancers(such as gastric cancer,colorectal cancer,liver cancer,laryngeal cancer,and pancreatic cancer)through a variety of pathways.The aim of this study is to investigate the mechanisms of action of the main components of ginger and their potential clinical applications in treating gastrointestinal tumors.
