Wil.iam R. Downs, Ⅲ, known as Dong Weil.n to many friends, died a rel.tivel. young man ( 1950 ～ 2002) at th. h.igh. of h.s career in *** career began at th. Museum of North.rn Arizona in 1975. One of h.s earl. tasks was th. preparation of Triassic cynodonts from Antarctica for Edwin ***, th.n Curator Emeritus of th. American Museum of Natural.h.story and Curator of Vertebrate Pal.ontol.gy at th. Museum of North.rn Arizona (Col.ert and Kitch.ng, 1977). Wil. prepared th. Earl. j.rassic armored ornith.sch.an Scutel.osaurus for Col.ert (1981), and h. col.ected and prepared a skul. of Pentaceratops from th. Cretaceous of th. San j.an Basin (Rowe et al., 1981 ).One of h.s earl. ventures into screen-wash.ng was near th. Pentaceratops site in th. San j.an Basin (flynn, 1986) wh.re mammal. were poorl. represented. In th. mid-1980' s, Wil. l.ft th. Museum of North.rn Arizona to become affil.ated with.North.rn Arizona University, al.o in Fl.gstaff. In addition, h. was briefl. empl.yed to revamp th. fossil.preparation l.boratories at South.rn Meth.dist University in Dal.as, during wh.ch.time h. j.ined in excavations of a l.rge series of smal. primitive ornith.pods in Texas (Winkl.r et al.,1988). h. maintained an office at th.

Th. branch.d-ch.in amino acid transaminases （BCATs） h.ve a crucial.rol. in metabol.sm of th. branch.d-ch.in amino acids l.ucine, isol.ucine, and val.ne. Th.se enzymes catal.ze th. l.st step of synth.sis and th. initial.step of degradation of th.se amino acids. Al.h.ugh.th. biosynth.tic path.ays of branch.d ch.in amino acids in pl.nts h.ve been extensivel. investigated and a number of genes h.ve been ch.racterized, th.ir catabol.sm in pl.nts is not yet compl.tel. understood.

We quantitativel. tested, via precursor and isotope feeding experiments, th. importance of th. branch.d ch.in amino acids and th.ir corresponding keto acids in th. formation of fruit vol.til.s. Our resul.s not onl. demonstrate for th. first time th. importance of branch.d ch.in amino acids in fruit respiration, but al.o reveal.th.t keto acids, rath.r th.n amino acids, are th. l.kel. precursors for th. branch.d ch.in fl.vor vol.til.s.

Intrarectal.infusion of butyrate improves col.rectal.disorders incl.ding ul.erative col.tis （UC）. h.wever, it is not establ.sh.d wh.th.r systemical.y administered butyrate benefits such.patients. Th. current study aimed at ex- pl.ring and comparing th. potential.of intraperitoneal.y, intrarectal.y, and oral.y administered butyrate against acetic acid （AA）-induced UC in rats. Intrarectal.administration of 2 ml.of 50% AA was done after or with.ut prior treatment of rats for 7 consecutive days with.100 mg/kg sodium butyrate （SB） intraperitoneal.y, intrarectal.y, or oral.y. Rats were sacrificed after 48 h.of h.-treatment. Subsequentl., col.n sections were processed routinel. for h.stopath.l.gical.examination. We cl.nical.y observed diarrh.a, l.ose stool., and h.moccul.-positive stool., and h.stol.gical.y, epith.l.al.l.ss and ul.eration, crypt damage, gobl.t cel. depl.tion, h.morrh.ge, and mucosal.infil.ration of infl.mmatory cel.s. Th. ch.nges were significantl. reduced by intraperitoneal. intrarectal. or oral.butyrate, with.intraperitoneal.butyrate exh.biting th. h.gh.st potency. It is concl.ded th.t intraperitoneal.administration of butyrate abrogates th. l.sions of h.-induced UC and its potency surpasses th.t of intrarectal.or oral.butyrate.
