Avaliação do potencial anti-inflamatório de composto tipo heparina (cCTH) extraído do caranguejo Goniopsis cruentata em modelo experimental de peritonite

Heparin, a sulfated polysaccharide, was the first compound used as an anticoagulant and antithrombotic agent. Due to their structural characteristics, also has great potential anti-inflammatory, though such use is limited in inflammation because of their marked effects on coagulation. The occurrence of heparin-like compounds that exhibit anticoagulant activity decreased in aquatic invertebrates, such as crab Goniopsis cruentata, sparked interest for the study of such compounds as anti-inflammatory drugs. Therefore, the objective of this study was to evaluate the potential modulator of heparin-like compound extracted from Goniopsis cruentata in inflammatory events, coagulation, and to evaluate some aspects of its structure. The heparin-type compound had a high degree of N-sulphation in its structure, being able to reduce leukocyte migration into the peritoneal cavity at lower doses compared to heparin and diclofenac sodium (anti-inflammatory commercial). Furthermore, it was also able to inhibit the production of nitric oxide and tumor necrosis factor alpha by activated macrophages, inhibited the activation of the enzyme neutrophil elastase in low concentrations and showed a lower anticoagulant effect in high doses as compared to porcine mucosal heparin. Because of these observations, the compound extracted from crab Goniopsis cruentata can be used as a structural model for future anti-inflammatory agents

Avaliação das características de carcaça e perfil dos ácidos graxos em suínos na fase de terminação, alimentados com dietas contendo farelo de bagaço de caju

Provide healthier meat to consumers of pig farmers has required an adjustment of nutrition and feed management. Nutrition is a primary factor in defining the qualitative aspects of pork, because through it we can modify the fatty acid profile. The objective of this study was to analyze the effects of adding bran bagasse cashew (FBC) in diets for finishing pigs, on carcass traits and meat quality. 20 crossbred barrows with an average initial weight of 57.93 ± 3.67 kg / BW were used Diets were formulated based on corn and soybean meal containing vegetable oil, commercial core and different levels of inclusion of the bran bagasse cashew ( 0.0, 7.5 % , 15.0 % , 22.5 % and 30.0 % ) . The experimental design was a randomized block with 5 treatments and 4 replications. Quantitative, qualitative, fatty acid profile of the longissimus muscle and fat area parameters were evaluated. It was observed that with the inclusion of FBC, the parameters of carcass yield, backfat thickness, fat area had a negative linear effect relationship and meat / fat positive effect. Regarding the profile of fatty acids in fat area, the content of linoleic fatty acid level of 30 % of FBC was 18.2 % higher ( P < 0.05 ) at the level of 0.0 % and the arachidonic level of 22.5 % was higher than 33.3 % and 37.5 % at levels of 0.0 % and 15.0 % ( FBC ) respectively. It is concluded that finishing pigs may be food diets containing up to 30 % of FBC, improving the quality of housing for lower fat deposition and modification in the fatty acid profile.
