《Diabetes & Metabolic Syndrome: Clinical Research & Reviews》2019,13(2):1225-1229
Background and objectivesThe present review shows a list of anti-glycation plants with their anti-glycation activity mechanisms that can attract the attention of pharmacologist for further scientific research towards finding better remedy for diabetic complications.MaterialsGoogle scholar, Pubmed, Web of Science and Scopus were searched. The terms were advanced glycation end products (AGEs), medicinal plants, antiglycation products.Resultsplants that studied in this review inhibit glycation in several possible mechanisms. Some of these plants inhibit the production of shiff base and amadori products. The others inhibit the generation of amadori products in the advanced phase. Some others blocked the aggregation of AGEs and some plants have antioxidant activity and reduce AGEs formation by preventing oxidation of amadori product and metal-catalyzed glucoxidation.ConclusionThis review can help pharmacologist to find antiglycation natural substance that can be useful in treatment of diabetic complications. 相似文献

Arthropod pests are responsible for major crop devastation and are vectors for the transmission of new and re-emerging diseases in humans and livestock. Despite many years of effective control by conventional agrochemical insecticides, a number of factors are threatening the effectiveness and continued use of these agents. These include the development of insecticide resistance and use-cancellation or de-registration of some insecticides due to human health and environmental concerns. Several approaches are being investigated for the design of new (bio)pesticides. These include the development of transgenic plants and recombinant baculoviruses as delivery systems for a variety of insect-selective toxins. Additional approaches for the development of foliar sprays include the rational design of peptidomimetics based on the key residues of these toxins that interact with the insect target. This special issue provides an overview of these phyletically selective animal, plant and microbial toxins and their diverse mechanisms of action to paralyze or kill arthropods. In addition, it reviews their potential for biopesticide discovery and validation of novel insecticide targets and provides an overview of the strengths and weaknesses of biopesticides in the global control of arthropod pests. 相似文献

Aim of the study
The main objectives were to collect information on the use of medicinal plants and compare medicinal plant traditions between Run and Qi.Materials and methods
Information was obtained from semi-structured interviews, personal conversation and guided fieldtrips with herbalists.Results
385 species belonging to 290 genera in 104 families were used for the treatment of various diseases. Rubiaceae (20 species), Euphorbiaceae and Compositae (19 species respectively) were predominant families used by herbalists. The most species were used for injuries (20.1%), muscular–skeletal system disorders (18.3%) and infections/infestations (18.0%). The coefficient of similarity (36.6%) shown a high consensus of plant species used by Run and Qi. The ‘informant agreement ratio’ values for both Run and Qi are rather low (less than 0.3).Conclusions
Traditional medicinal plants still play an important role in medical practices of Li Ethnic Group around Mt.Yinggeling. There is a close relationship of medicinal plant traditions between Run and Qi. Further investigation is necessary to record this valuable knowledge before its disappearance. 相似文献5.

This study attempts to demonstrate the existence of allergic contact dermatitis from grass, and to develop a patch test series to screen patients with grass intolerance. 6 common grass species from lawns and military training areas were collected. Solvent extracts of polar. non-polar and volatile fractions were prepared and used for patch testing in 20 control subjects and 46 patients with a history of grass intolerance. The 20 control had negative responses to patch testing. 5 out of 46 patients had positive patch tests to Axonopus compressus (carpet grass). Ischaenmum muticum (sea-shore centipede grass). Imperata evlindrica (lalang). Panicum maximum (Guinea grass) and Pennisetum purpureum (elephant grass). Reactions to the non-polar fraction for all 5 species were noted. This study demonstrates the existence of allergic contact dermatitis from various common species of grass. In our series, this is seen in 11% of those with a history of grass intolerance. 相似文献
