AIM: To test whether antioxidant treatment could prevent the progression of Barrett's esophagus to adenocarcinoma. METHODS: In a rat model of gastroduodenoesophageal reflux by esophagojejunal anastomosis with gastric preservation, groups of 6-10 rats were randomized to receive treatment with superoxide dismutase (SOD) or vehicle and followed up for 4 too. Rat's esophagus was assessed by histological analysis, superoxide anion and peroxinitrite generation, SOD levels and DNA oxidative damage. RESULTS: All rats undergoing esophagojejunostomy developed extensive esophageal mucosal ulceration and inflammation by mo 4. The process was associated with a progressive presence of intestinal metaplasia beyond the anastomotic area (9% 1st mo and 50% 4th too) (94% at the anastomotic level) and adenocarcinoma (11% 1^ST mo and 60% 4th too). These changes were associated with superoxide anion and peroxinitrite mucosal generation, an early and significant increase of DNA oxidative damage and a significant decrease in SOD levels (P〈0.05). Exogenous administration of SOD decreased mucosal superoxide levels, increased mucosal SOD levels and reduced the risk of developing intestinal metaplasia beyond the anastomotic area (odds ratio = 0.326; 95%CI: 0.108-0.981; P = 0.046), and esophageal adenocarcinoma (odds ratio = 0.243; 95%CI: 0.073-0.804; P = 0.021). CONCLUSION: Superoxide dismutase prevents the progression of esophagitis to Barrett's esophagus and adenocarcinoma in this rat model of gastrointestinal reflux, supporting a role of antioxidants in the chemoprevention of esophageal adenocarcinoma. 展开更多

Fatty acid synthase (FAS) attracts more and more attention recently as a potential target for metabolic syndrome,such as cancer, obesity, diabetes and cerebrovascular disease. FAS inhibitors are widely existed in plants, consisting of diversiform compounds. These inhibitors exist not only in herbs also in many plant foods, such as teas, allium vegetables and some fruits. These effective components include gallated catechins, theaflavins,flavonoids, condensed and hydrolysable tannins, thioethers,pentacyclic triterpenes, stilbene derivatives, etc, and they target at the different domains of FAS, showing different inhibitory mechanisms. Interestingly, these FAS inhibitor-contained herbs and plant foods and their effective components are commonly related to the prevention of metabolic syndromes including fatreducing and depression of cancer. From biochemical angle,FAS can control the balance between energy provision and fat production. Some studies have shown that the effects of those effective components in plants on metabolic syndromes are mediated by inhibiting FAS. This suggests that FAS plays a critical role in the regulation of energy metabolism, and the FAS inhibitors from plants have significant potential application value in the treatment and prevention of metabolic syndromes. 展开更多

To understand how baking processes influence starch quality, twelve samples of cereal foods products have been studied. Damaged starch determined by a-amylase hydrolysis to characterize and quantify the molecular composition of cereal foods starches treated with different conditions during processing that had been physically damaged to different extents, by preparation and processing provide the physicochemical data to understand more fully the effects of mechanical damage on amylase, amylopectin content and differential scanning calorimetric (DSC) for selected cereal foods products. There were significant difference between treatments in term of damaged starch content of cereal foods flours which were 0.64% to 36.40%, while the DSC results for the starches were the gelatinisation onset (To), peak temperature (Tp) and conclusion temperature (To), and temperatures of selected food starches ranged from 34.86 ℃ to 75.20 ℃, 54.04 ℃ to 85.94 ℃, and 63.5 ℃ to 95.16 ℃. There were significant differences between all cereal foods starches in term of amylose and its contents ranged from 70.3% to 87% and also there were significant differences between the amylopectin content of cereal foods flours ranged from 13.3% to 29.6%. 展开更多

The objective of this study was to investigate the influence ofa phytogenic feed additive (PFA) to late-gestation (d 90) and lactation sows on their reproduction performance. Sixty Large White × Landrace primiparous sows were divided into four groups (fifteen sows per group). The control group was fed with basal diet, the others were fed with basal diet supplemented with 0.02%, 0.04% and 0.06% PFA, respectively. Compared with the control, the sows in 0.04% PFA group had higher feed intake during lactation and higher litter weaning weight (P 〈 0.05). At farrowing, glucose level in 0.04% PFA sows was higher than the control and sows in 0.02% PFA had the highest IgG content among the treatments (P 〈 0.05). On day 7 of lactation, serum urea nitrogen contents were lower in response to PFA supplementation compared to the control (P 〈 0.05). At the same time, sows fed the 0.06% PFA diet increased the lysozyme activity (P 〈 0.05). The levels of milk lactose and IgG were increased in 0.02% and 0.04% PFA groups (P 〈 0.05). In conclusion, feeding PFA improved sows and litter performance, serum metabolite concentrations, lgG level and lysozyme activity at postpartum and milk quality. 展开更多
