The purpose of this study was to investigate the effect of different doses o f dietary fiber of Tremella fuciformis Berk on lipid metabolism and inte stinal physiology in rats fed diets containing 1% cholesterol and 0.2% cholica cid. Forty-two male Wistar rats were randomly divided into six groups in a 2× 3 factorial design and were fed diets containing different doses (0%、5% or 10 %) of dietary fiber of TFB, with and without antibiotics 0.7g/100g of Nebaci tin (bacitracin: neomycin sulfate = 2:1,w/w) for 4 weeks. The parameters analyz ed included liver and serum lipid concentration , serum and caecal content of short chain fatty acids ,fecal neutral steroids and total bile acids content.T he results showed that rats fed the diet with antibiotics had lower levels ofs hort chain fatty acids in serum and caecal content than rats fed diet withouta ntibiotics.

中文摘要本研究乃欲探讨在有高胆固醇饮食条件下，摄取不同量的白木耳膳食纤维及添加抗生素对大白鼠脂质代谢及肠道生理的影响。42只 Wistar 品系雄鼠(重约260g)，随机分为六组，每组饲料中均添加 1%胆固醇及 0.2%胆酸，并以添加或不添加抗生素[ 0.7g Nebacitin(bacitracin：neomycin sulfate=2：1，w/w)/100g dry matter] 、白木耳膳食纤维量(0%、5%或 10%)作 2×3 factorial 之实验设计，实验期四周，分析血清及肝脏中脂质浓度，血清及盲肠内容物短链脂肪酸浓度，以及粪便中总中性固醇，总胆酸的含量。

The experiment two: enzyme preparation significantly improved average daily gainand feed conversion ratio (P＜0.05). Enzyme preparation significantly increased energymetabolizability and digestibility of crude fiber, crude protein and neutral detergent fiber,but had no remarkable effect on digestibility of dry matter, crude fat and acid detergentfiber. Enzyme preparation significantly decreased the relative viscosity of duodenal andjejunal digesta. The pH of intestine had no noticed difference in all groups. Enzymepreparation significantly decreased relative weight of gizzard, proventficulus, duodenum,jejunum and ileum. Enzyme preparation significantly increased villus size of duodenumand jejunum, and villus to crypt ratio of duodenum and ileum significantly increased too.Enzyme preparation considerably decreased ileal crypt height (P＜0.05), and didn"t affectthickness of intestinal wall. Supplementing enzyme preparation, the serum glucose, totalprotein and alanine aminotransferase, but enzyme preparation hadn"t noticed influenceupon uric acid, total cholesterol, triglyceride and high-density lipoproteins. Enzymepreparation significantly increased insulin, triiodothyronine and insulin-like growthfactor-Ⅰ. Adding enzyme preparation, the percentage of thyroid stimulating hormone andgrowth hormone in the serum increased 16.44%, 19.18% and 18.84%, 21.74%respectively, and the percentage of glucagon and thyroxine decreased 12.07%, 14.36% and 13.79%, 15.40%, but failed to reach statistical significance (P＞0.05). Enzymepreparation significantly increased (P＜0.05) the trypsin and amylase activity of duodenaland jejunal digesta, but enzyme preparation didnt affect significantly (P＞0.05) theintestinal lipase activity and pancreatic digestive enzyme. Enzyme preparation had nosignificant effect on caecal microbial population.

试验二：酶制剂显著提高平均日增重和饲料转化率(P＜0.05)；酶制剂显著提高能量代谢率及粗纤维、粗蛋白、中性洗涤纤维消化率(P＜0.05)，而对干物质、粗脂肪、酸性洗涤纤维消化率影响不显著；酶制剂显著降低十二指肠和空肠食糜相对粘度(P＜0.05)；添加酶制剂对肠道pH影响不显著；酶制剂显著降低肌胃、腺胃、十二指肠、空肠、回肠相对重(P＜0.05)，显著提高十二指肠和空肠绒毛高度，显著增加十二指肠和回肠绒毛高度／隐窝深度，降低回肠隐窝深度(P＜0.05)，对肠壁厚度影响不显著；酶制剂显著提高血清葡萄糖、总蛋白和谷丙转氨酶浓度(P＜0.05)，对尿酸、总胆固醇、甘油三酯及高密度脂蛋白浓度影响不显著，显著提高胰岛素、T_3、IGF-Ⅰ水平，添加酶制剂后，促甲状腺激素、生长激素分别提高16.44％、19.18％和18.84％、21.74％，胰高血糖素和T_4分别降低12.07％、14.36％和13.79％、15.40％，但差异不显著；酶制剂对胰腺消化酶活性影响不显著，显著增加十二指肠和空肠胰蛋白酶、淀粉酶活性，对小肠脂肪酶活性影响不显著；酶制剂对盲肠微生物菌落数影响不显著。
