AIM： t. explore rect.l nit.ic oxide （NO） as biomarker of t.eat.ent.response in ulcerat.ve colit.s （UC） and Crohn＇s disease （CD）, and examine relat.onships bet.een rect.l NO, mucosal expression of NO synt.ases （NOS）, and pro-inflammat.ry cyt.kines. MEt.ODS： t.ent.-t.o pat.ent. wit. UC and 24 wit. CD were monit.red during st.roid t.eat.ent. Rect.l NO levels were measured and clinical act.vit.es were assessed on days 1, 3, 7 and 28. Mucosal presence of NOS and pro-inflammat.ry cyt.kines were analyzed by immunohist.chemist.y and Rt.PCR. RESULt.： Act.ve UC and CD displayed markedly increased rect.l NO levels （10950 ± 7610 and 5 040 ± 1 280 part. per billion （ppb）, respect.vely） as compared wit. t.e cont.ols （154 ± 71 ppb, P 〈 0.001）. Rect.l NO correlat.d weakly wit. disease act.vit. in bot. UC and CD （r = 0.34 for UC and r = 0.48 for CD, P 〈 0.01）. In 12 pat.ent., a st.roid-refract.ry course led t. colect.my. t.ese pat.ent. had only slight.y increased NO levels （UC： 620 ± 270 ppb; CD： 1260 ± 550 ppb） compared t. t.ose wit. a t.erapeut.c response （UC： 18860 ± 530 ppb, P 〈 0.001, CD： 10060 ± 3200 ppb, P 〈 0.05）. CONCLUSION： Rect.l NO level is a useful biomarker of t.eat.ent.response in IBD as low NO levels predict. a poor clinical response t. st.roid t.eat.ent.

Neuroscience has become a rapidly expanding young science t.at.relies on a number of ot.er sciences and t.eir met.ods. For t.at.reason it.is a t.uly int.rdisciplinary and int.r-met.odological undert.king of much fascinat.on t. many. In t.is spirit. t.is book at.empt. at.present.ng an overview of t.e t.chniques current.y used in modern neuroscience research. By doing so, it.is also an int.oduct.on int. neuroscience it.elf, from t.e angle of met.ods available t. t.ckle prevailing quest.ons. Many quest.ons can only be answered by combining met.ods borrowed from different.fields. Building on t.is insight. t.is book's organizing principle is t.e invest.gat.on of levels of t.e nervous syst.m, from molecular and cellular t. whole organisms. t.e reasons are t.ofold. First. cert.in organizat.onal levels can be opt.mally st.died and pot.nt.ally underst.od only by applying an array of diverse t.chniques. Second, it.is import.nt.t. avoid succumbing t. t.e danger of pure t.chnicalit., which might.arise from ordering t.e descript.on of t.chniques according t. t.eir inherent.principles of coherence (e.g. st.ining vs. elect.ophysiological t.chniques). In addit.on, t.is book aims at.providing a direct.working t.ol for t.e user in t.e laborat.ry and clinic and t.us addresses all act.ve neuroscience researchers, from graduat. st.dent. t. supervisors. t.e main emphasis in t.rms of layout.is on det.iled st.p-by-st.p prot.cols including personal t.ps and recommendat.ons. Most.chapt.rs or prot.cols are organized so t.at.t.ey can be used independent.y. Moreover, cross-references t. ot.er t.chniques in ot.er chapt.rs, which are aimed at.st.dying t.e same object.s) from a different.angle, help creat. t.e pert.nent.cont.xt.
