Nutritional status and nutritional therapy in inflammatory bowel diseases

Underweight and specific nutrient deficiencies are frequent in adult patients with inflammatory bowel disease(IBD).In addition,a significant number of children with IBD,especially Crohn's disease(CD) have impaired linear growth.Nutrition has an important role in the management of IBD.In adults with CD,enteral nutrition(EN) is effective in inducing clinical remission of IBD,although it is less efficient than corticosteroids.Exclusive EN is an established primary therapy for pediatric CD.Limited data suggests that EN is as efficient as corticosteroids for induction of remission.Additional advantages of nutritional therapy are control of inflammation,mucosal healing,positive benefits to growth and overall nutritional status with minimal adverse effects.The available evidence suggests that supplementary EN may be effective also for maintenance of remission in CD.More studies are needed to confirm these findings.However,EN supplementation could be considered as an alternative or as an adjunct to maintenance drug therapy in CD.EN does not have a primary therapeutic role in ulcerative colitis.Specific compositions of enteral dietselemental diets or diets containing specific components-were not shown to have any advantage over standard polymeric diets and their place in the treatment of CD or UC need further evaluation.Recent theories suggest that diet may be implicated in the etiology of IBD,however there are no proven dietary approaches to reduce the risk of developing IBD.

Importance of nutrition in inflammatory bowel disease

Inflammatory bowel disease （IBD） results from the interaction between an individual＇s immune response and precipitant environmental factors, which generatean anomalous chronic inflammatory response in thosewho are genetically predisposed. Various feeding practices have been implicated in the origin of IBD based on epidemiological observations in developed countries, but we do not have solid evidence for the etiological role played by specific food types. IBD is associated with frequent nutritional deficiencies, thepattern and severity of which depends on the extent,duration and activity of the inflammation. Nutritional support allows these deficiencies in calories, macro and micronutrients to be rectified. Enteral nutrition is also aprimary therapy for IBD, especially for Crohn＇s disease,as it allows the inflammatory activity to be controlled,kept in remission, and Drevents or delays the need forsurgery. Nutritional support is especially important in childhood IBD as an alternative to pharmacological treatment. This report discusses the complex relationship between diet and IBD.

Obtaining Cheese with Milk Mixture and Inca Peanut （Plukenetia Volubilis）

The Inca peanut, a plant native to the Peruvian Amazon, has an important nutritional contribution to 53% oil and 33% protein [ 1, 2], high content of Omega 3 and 6, Vitamin E. Recent research suggests the nutritional and therapeutic significance of consumption for the control of free radicals [3], being an alternative food to reduce nutritional deficiencies of macro and micronutrients in the diet. The results show that the cheese made from a mixture of milk and Inca peanut （70：20 v/v） 0.15 M of Ca sulphate is of firm consistency, with a clotting time of 9 min and yields 14.56% at 80 ℃, is similar to fresh milk cheese sensory characteristics determined by the test of acceptability. Respect to nutrition cheeses present values of protein and fat （16.3% and, 25.05%, respectively）. Sensory evaluation process cheese 70：30 v/v showed an acceptance of 67% relative to a commercial cheese. The texture profile of the finished product, applying a deformation of 30%, have hardness values for 1.88 N, elasticity 0.08, cohesiveness 0.86, adhesiveness 0.36, gumminess 1.62 and chewiness 0.13.

Tissue Culture and Gemmae Propagation of Shoot Tipof Huperzia serrata

To solve the problems of microbial contamination and no rooting during the tissue culture of Huperzia serrata, wild seedlings of Huperzia serrata were cultured by indoor hydroponics or soil cultivation methods, then the stem tips were used in tissue culture. The above operation significantly reduced microbial contamination during tissue culture process. Different types and concentrations of hormones were added into the basic medium MS to screen the optimal formula for induced plantlet growth and rooting. It was found that 1/2MSCO was the best medium on which stem, leaves and roots of tissue culture plantlets of Huperzia serrata grew quickly. At the same time, sand planting was a convenient and effective approach for gemmae propagation of Huperzia serrata, the survival rate of seedlings germinated from gemmae was nearly 100%.

Seasonal variation in fatty acid composition of seston and the copepod Calanus sinicus(Brodsky,1962)in Jiaozhou Bay and its trophic implications

The fatty acid compositions of seston and Calanus sinicus were investigated to study trophic relationships in Jiaozhou Bay. Principal component analysis was carried out to ordinate the fatty acid patterns of seston in stations and months. The results showed that diatoms were most abundant in the phytoplankton at station A5 （located in the northwest of the bay： 36~9＇N, 120~20＇E） and least abundant at station D7 （located outside of the bay： 35~59＇N, 120~26＇E）. By contrast, dinoflagellates were most abundant at station D7 and least abundant at station A5. According to the annual variations of 16：1 （o7 and 18：4（o3/ 16：1（o7, diatoms flourished mainly in spring and summer, while dinoflagellates bloomed exclusively in summer. A distinctive feature of the fatty acid composition of C. sinicus was the prevalence of 20：5o3 and 22：6（o3. The higher content of 16：1（o7 over 18：4（o3 in females indicated that diatoms contributed more than dinoflagellates to the diet of C. sinicus. The feeding intensity of C. sinicus on diatoms was higher in spring and autumn than in other seasons. The herbivorous indicators 20：1 and 22：1 were comparatively low, suggesting that besides phytoplankton, C. sinicus might feed on a wider range of particles including organic detritus, bacteria and small copepods.

Effects of temperature and salinity on the development of the amphipod crustacean Eogammarus sinensis

The amphipod crustacean Eogammarus sinensis has useful features that make it suitable for use in the aquaculture of fish and large decapod crustaceans.In this study,we investigated the effects of temperature and salinity on the development,fecundity,survival,and growth rate of E.sinensis.The results show that temperature significantly affected E.sinensis development,but salinity.As temperature increased,the duration of E.sinensis embryonic development decreased.Fecundity was affected significantly by temperature and the combination of temperature and salinity,but by salinity alone.In addition,high temperatures accelerated E.sinensis juvenile growth rates,whereas high salinity reduced it.Therefore,our data suggest that E.sinensis tolerates a wide range of salinities and that temperature has more significant effects than salinity on the embryonic development,fecundity,and growth of E.sinensis.Our results shall be useful for mass production of this species for use in aquaculture.
