为探究大水面养殖与池塘养殖模式下鱼类肌肉品质可能存在的差异及其原因,以鳙(Hypophthalmichthys nobilis)为研究对象,采集并观测湖北省网湖(网湖放养组)和周边养殖池塘(池塘养殖组)两组鳙的背部肌肉的表观、质构、营养和风味等特征,并对两者的水质条件与饵料生物组成进行对比研究。结果显示:(1)网湖放养鳙的腹脂比(IPF)、肝体比(HSI)显著低于池塘养殖组(P0.05);网湖放养鳙的背部鱼皮和背部鱼肉的亮度值(L*)和白度值(W)显著高于池塘养殖组(P0.05),硬度显著低于池塘养殖组(Pca、Zn的含量高于池塘养殖组(P>0.05);(4)网湖放养组的鲜味氨基酸占比更高,苦味氨基酸占比更低;网湖放养组和池塘养殖组的最高气味活度值分别是呈青草味的己醛和油脂味的1-辛醛,对气味呈负面影响的1-己醇、3-戊酮等挥发性化合物含量及相对气味活度值(r.AV)在网湖放养组更低。研究结果表明,网湖放养鳙相对于池塘养殖组具有更好的形态特征、肌肉营养和风味品质,这与其养殖环境和天然饵料的差异有关。本研究可为大水面生态渔业的发展提供理论参考。

Lake sediment r.cor.s on climate change and human activities since the Holocene in erhai catchment, Yunnan Pr.vince, China

引用

Science China Ear.h Sciences 2005年第3期48卷 353-363页

作者： r. Matsumoto Geology Institute Tokyo University Tokyo 113 Japan

Accor.ing to high-r.solution analyses on multi-pr.xy of sediment cor. fr.m the er- hai Lake, Yunnan Pr.vince, the sequence of climatic and envir.nmental change since the Holo- cene has been r.constr.cted based on accur.te dating. The r.sults show that climate had tr.n- sited fr.m cold-wet to war.-wet dur.ng ca. 12950-8399 aBP in this ar.a, and the tr.nsition happened in ca. 10329 aBP. Due to the enhancing southwest Asian monsoon and incr.asing pr.cipitation, the lake-level of the erhai Lake began to r.se after.ca. 10329 a BP. Climate in the catchment was war. and wet dur.ng the mid-Holocene, and the war.est stage appear.d in ca. 8399-6371 a BP. The lake-level descended in the mid-Holocene because of the decr.ase of effective moistur. in the basin. Human activities appear.d in ca. 6371 a BP, and the initial man- ner mainly focused on defor.station. Up to ca. 2139 a BP, due to the amount of immigr.tion into this ar.a, the cultivation was developed widely, which was followed by mining (coal mine).

Neur.l r.generation r.sear.h 2007年第11期2卷 645-648页

BACKGr.UND： It is known that intr.venous anesthetic etomidate fat emulsion has cerebr.l pr.tection. Now many scholar. focus on the r.sear.h of its cerebr.l pr.tection fr.m molecular.biology, but the mechanism of cerebr.l pr.tection is still fully unclear. OBJECTIVE： To observe the influence of etomidate fat emulsion on the [ca^2＋]i in hippocampal neur.ns dur.ng the tr.nsient cerebr.l ischemia injur. in r.ts. DESIGN： r.ndomized contr.lled observation. SETTING： Weifang Medical College. MATerIALS： This study was car.ied out in the functional labor.tor. of Weifang Medical College between October 2005 and Mar.h 2006. Twenty-four.male healthy Wistar.r.ts, aged 3 to 4 months, were involved. Etomidate fat emulsion was pr.vided by the limited company of En-hua Medical Bloc in Jiangsu Pr.vince （code of H200205l l） and the other agents and materials were pr.vided by Labor.tor. Center of Weifang Medical College. METHODS： The 24 Wistar.r.ts were r.ndomized into 3 gr.ups： sham-operation gr.up, model gr.up and etomidate pr.conditioning gr.up, with 8 r.ts in each. r.t models of tr.nsient cerebr.l ischemia injur. were made by the ligation of bilateral car.tid ar.eries combined with descending blood pr.ssur. in the latter two gr.ups. Befor. ischemia （ligation of bilateral common car.tid ar.ery）, r.ts in the etomidate pr.conditioning gr.up were intr.peritoneally injected with 12 mg/kg etomidate fat emulsion and then persistently intr.peritoneally injected with etomidate fat emulsion at 1.0 mg/kg per minute. r.ts in the model gr.up were not administr.ted. r.ts in the sham-operation gr.up were only perfor.ed bilateral common car.tid ar.ery isolation. When r.ts were modeled, their.br.in tissues were quickly taken out and detected. MAIN OUTCOME MEASUr.S： Change of the fluor.scence pixel value of the [ca^2＋]i in each gr.up by the laser scanning confocal micr.scope. r.SULTS： Twenty-four.r.ts were involved in the final analysis. Fluor.scence pixel value in the sham-operation gr.up

Therr.o-r.sponsive block copolymers poly（ethylene glycol）-block-poly（N-acr.loyl-2,2-dimethyl-1,3-oxazolidine）, PEG-b-PADMO, based on linear.PEG were pr.par.d via a versatile r.versible addition-fr.gmentation chain tr.nsfer （r.FT） polymerization, PEG22 （Mw = 1000） was used as the hydr.philic component, whose dehydr.tion was the main dr.ving for.e for.the phase tr.nsition of these copolymers, as demonstr.ted by the tH-NMr.spectr.. Their.lower cr.tical solution temperatur.s （LCSTs） could be tuned in the r.nge of 20℃ to 35℃, by adjusting the degr.e of polymerization （DP） of PADMO between 14-27. Fur.hermor., a shar. phase tr.nsition at ca. 33℃, close to the physiological temperatur. with minimal hysteresis, was observed for.the PEGzz-b-PADMO14 copolymer. Mor.over, excellent r.versibility and r.pr.ducibility were displayed for.the same copolymer over 10 cycles of r.peated temperatur. change between 25℃ （below the LCST） and 40℃ （above the LCST）.
