Exopolysaccharides (EPS) was extracted from Tremella fuciformis growth in solid medium contained sorghum seeds. The objective of present work was analyzed EPS and evaluate the effect on the glucose, cholesterol, HDL, triglycerides, glutamic-pyruvic transaminase (GPT), urea level in the plasma of rats with type 1 diabetes mellitus (DM1) induced by high sugar diet and streptozotocin. Beta-glucan and total sugar from T. fuciformis was determined and the major quantity was alfa linked glucose. Concentration used for animals was 1mmol and 2mmol of EPS. Male Wistar rats were separated in two groups where one was induced diabetes mellitus (DM1) with streptozotocin and another with high sugar diet. The rats were allocated as follows: control that received commercial pellet; control that received polysaccharide; diabetic group that received streptozotocin or high sugar diet; diabetic group that received 1mmol or 2mmol from polysaccharide obtained from different T. fuciformis isolate. In group that received streptozotocin were evaluated results until 35days but in another group with high sugar diet the results go to 60days. Weight and blood glucose levels were measured once a week and after the period from experiment the animals were euthanized and blood was collected for the analysis of cholesterol, HDL, triglycerides, GPT and urea. Results indicate that EPS is beneficial in control of DM1 when the level from blood glucose is until 130mg/dL accomplished by reducing cholesterol, triglyceride, GPT, urea and increasing HDL cholesterol. When the blood glucose level is above 200mg/dL the action of EPS in reducing is not satisfactory. The T. fuciformis solution did not show anti-inflammatory activity.

In barley plants (BRS-195), the disease detected as spot blotch is caused by Bipolaris sorokiniana, and is the most deleterious disease for the producers and the beer industry. For fungicides mediated control of this disease can cause risks to environment and human health. To eliminate these drawbacks, one of the methods considered is the use natural products. The purpose of the present study was to investigate the use of extract of leaves from Bauhinia variegata Link. and Opera® fungicide (active ingredient: pyraclostrobin) for controlling Bipolaris sorokiniana in barley plants. In Brazil there are two species of Bauhinia are seen, namely Bauhinia forficata and B. variegate. Extracts from B. variegata didn't show fungitoxic action but B. forficata the action exist. The barley plant showed protection of 92 to 100% in local and systemic action. The chemical TLC assays showed the presence of phenols (rutin, coumaric acid, kaempferol) that can be related to a signal for activation of the defense responses against pathogen or mechanism of salicylic acid. Treatment with fungicide Opera® gave another mechanism and have only 60% of protection.
