The sectioned thin cell layers (TCL) of flower stalk of Cichorium intybus L. were cultured in MS medium supplemented with NAA and BA or IAA and BA where floral and vegetative buds were developed from the explant. Endogenous IAA, DHZ+DHZR, iPA increased significantly during the floral bud formation, while Z+ZR remained changed. The levels of cytokinins, DHZ+DHZR, iPA, and Z+ZR all increased significantly during the vegetative bud formation, however IAA level was reduced during the first 7 days of culture and increased to two thirds of initial values on the day when the bud primordia were formed. The results suggested that the initiation of floral buds was associated with a high IAA/CTK ratio, whereas the induction of vegetative bud differentiation was related to a low IAA/CTK ratio. 展开更多

[Objective] The aim was to explore recycling utilization of manure of dairy cattle through returning of manures into fields. [Method] Effects of dairy cattle ma- nure and chemical fertilizer on fertility of soils grown with Cichorium intybus were in- vestigated through a pot experiment. [Result] After manure of dairy cattle was ap- plied, it can be concluded that organic matter, total N, total P, alkali-hydrolyzable ni- trogen, available P, activities of urease and invertase in soils increased by 0.14-1.28 times, 43.8%-79.7%, 17.4%-30.8%, 147%-188%, 7 times, 17.2%-38.5%, and 1.36%- 3.34%, respectively. Furthermore, organic matter, total N. urease and invertase activi- ties in group of M7F3 increased most; total P and available P achieved the best in group of M3F7. These indicated that the applied manures of dairy cattle would maintain and improve soil fertility, providing better soils for Cichorium intybus. [Conclusion] The research provides reference for recycling of cattle manures and construction of ecological cyclical pattern of "grass planting-cattle breeding-methane fermentation-returning of manures into fields". 展开更多

The prevalence of nonalcoholic fatty liver disease (NAFLD) as a metabolic disorder affecting the liver function is rapidly increasing and there is a need to develop new and more efficient treatment. This study was designed to evaluate the protective effect of Cichorium intybus L. and Cinnamon mixture infusion (2.5 and 0.5 g/100mL and twice/day) on patients with NAFLD. This before-after clinical trial study was performed on 25 patients with NAFLD. They were administered the mixture of extract prepared in special bags twice a day for 30 days. Hepatic and metabolic markers of NAFLD like alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphates (ALP), fasting blood sugar (FBS), cholesterol (chol), triglycerides (TG), high-density lipoprotein (HDL) and low-density lipoprotein (LDL) in plasma and also, fatty liver ultrasonographic grading were determined before and after using the extracts. 30-day treatment with extracts in NAFLD patients resulted in a significant decrease in ALT and AST. FBS, TG and ALP were also decreased after administration of the extracts but not significantly. A significant linear correlation was found between age and ALP, and between gender and liver enzymes. It is concluded that the mixture of Cichorium intybus L. and Cinnamon extracts has some benefits in NAFLD patients making them valuable for future investigations. 展开更多

[Objective] This study aimed to investigate the effects of space mutation on the activities of protective enzymes in different strains of Cichorium intybus L. and provide theoretical basis for screening drought-tolerant plants in southern karst area. [Method] C. intybus seeds were sent into outer space by 'Shijian No.8' seed- breeding satellite. The new strains and original variety of C. intybus L. were used as experimental materials to determine the activities of catalase (CAT), peroxidase (POD), superoxide dismutase (SOD), and malondialdehyde (MDA) content. [Result] The results showed that MDA content in PA-82, Puna chicory and PA-43 increased gradually with the increase of water stress duration, which was enhanced by 0.575, 0.72 and 0.844 μmol/g respectively at 12 days. In addition, the activities of SOD, POD and CAT increased rapidly; at 9 days, the activities of SOD in PA-82, Puna chicory and PA-43 were enhanced by 878.9, 809.2 and 711.1 U/g, with the increas- ing range of 139.1%, 136.7% and 121.1%, respectively; the activities of POD were enhanced by 4 397, 3 754 and 2 767 U/(g ·min), with the increasing range of 265.84%, 257.65% and 204.06%, respectively; the activities of CAT were enhanced by 402.1, 277.1 and 170.9 KU/L, with the increasing range of 73.08%, 39.69% and 26.20%, respectively; subsequently, the activities of these three protective enzymes were reduced significantly; at 12 days, the activities of SOD in PA-82, Puna chicory and PA-43 were reduced to 1206.5, 1144.7 and 1108.6 U/g, respectively; the activi- ties of POD were reduced to 3 145, 2 876 and 2 753 U/(g·min) , respectively; the activities of CAT were reduced to 587.2, 698.1 and 584.1 KU/L, respectively. [Con- clusion] According to the results of comprehensive evaluation, drought resistance in three C. intybus varieties exhibited a descending order of PA-82 〉 Puna chicory 〉 PA-43. 展开更多

There is a dramatic increase in the prevalence of nonalcoholic fatty liver disease, which is slowly turning into apandemic as well as a major challenge across the world. Nonalcoholic fatty liver disease is described as a range ofliver conditions such as fat accumulation, hepatic steatosis, or end-stage liver disease. Patients with nonalcoholicfatty liver disease are asymptomatic and their mortality is higher than people without nonalcoholic fatty liverdisease. The pathogenesis of nonalcoholic fatty liver disease has not been clearly determined yet. The “two hits”hypothesis is designed to explain the pathogenesis of nonalcoholic fatty liver disease. Dyslipidemia, oxidativestress, insulin resistance, obesity, and chronic inflammation are some of the morbidities involved in the progressionof nonalcoholic fatty liver disease. Chicory (Cichorium intybus L.) is an herbaceous perennial, known as chicory.Chicory contains various compounds, such as vitamins, sonchuside A, caffeic acid derivatives,fructo-oligosaccharides, chlorogenic acid, magnolialide, polysaccharides, coumarins, phenolic acids, terpenoids,flavonoids, polyphenol, cichoriosides, ixerisosides, eudesmanolides, inulin, bitter sesquiterpene lactones, andalkaloids. Current research has revealed that chicory supplementation might be effective in the treatment ofnonalcoholic fatty liver disease. The anti-inflammatory, antihepatotoxic, antihyperlipidemic, antidiabetic,antihyperglycemic, and antioxidant properties of chicory provide plausible mechanisms by which chicory mayaffect the various steps of disease progression and severity. Existing studies have shown that chicorysupplementation has beneficial effects on nonalcoholic fatty liver disease, but the existence of only one humanstudy and possible side effects of chicory necessitate further studies. 展开更多

Increasing consumer awareness of health and climate is being reflected in their dietary choices.This is reflected in the strong growth in the market for plant-based food,with plant-based burgers(PBB)being the most popular meat alternative.PBB must be based on natural ingredients that increase nutritional value,improve technological properties,and create satisfying physical sensations.Fibers obtained from agri-food by-products can potentially meet all of these requirements.The dietary fiber concentrate(DFC)produced from the forced roots of Belgian endive(Cichorium intybus var.foliosum)(by-product)has shown potential for application in PBB.Replacing soy protein with 5%and 10%of DFC from Belgian endive(DFC-BE)resulted in lower caloric value and sugar content and doubled dietary fiber concentration in the end product,enough to justify a“high fiber”nutrition claim(>6 g per 100 g).Baking properties such as baking yield,moisture retention,and dimeter reduction also improved.Application of DFC-BE can also be used to regulate pH,color,texture profile,and sensory attributes.Individual recipes must be adjusted to obtain the required results. 展开更多
