OBJECt.VE： t. det.rmine t.e role of a pharmacokinet.c int.ract.on in t.e prot.ct.ve effect.of curcumin against.t.e gast.ic damage induced by indomet.acin administ.at.on as such or as it. prodrug acemet.cin. MEt.ODS： Wist.r rat. orally received single dose of indomet.acin （30 mg/kg） wit. and wit.out.curcumin （30 mg/kg）; gast.ic injury was evaluat.d by det.rmining t.e t.t.l damaged area. Addit.onal groups of rat. received an oral single dose of indomet.acin （30 mg/kg） or it. prodrug acemet.cin （34.86 mg/kg） in t.e presence or absence of curcumin （30 mg/kg）. Indomet.acin and acemet.cin concent.at.ons in plasma from blood draws were det.rmined by high-performance liquid chromat.graphy Plasma concent.at.on-against.t.me curves were const.uct.d, and bioavailabilit. paramet.rs, maximal concent.at.on （Cmax） and area under t.e curve t. t.e last.sampling t.me （AUC0_t. were est.mat.d. RESULt.： Concomit.nt.administ.at.on of indomet.acin and curcumin result.d in a significant.y reduced gast.ic damage compared t. indomet.acin alone. However, co-administ.at.on of curcumin did not.produce any significant.alt.rat.on in t.e bioavailabilit. paramet.rs of indomet.acin and acemet.cin aft.r administ.at.on of eit.er t.e act.ve compound or t.e prodrug. CONCLUSION： Curcumin exhibit. a prot.ct.ve effect.against.indomet.acin-induced gast.ic damage, but.does not.produce a reduct.on of t.e bioavailabilit. of t.is nonst.roidal ant.-inflammat.ry drug, indomet.acin. Dat. t.us suggest.t.at.a pharmacokinet.c mechanism of act.on is not.involved in curcumin gast.oprot.ct.on.

MEt.ODS. t.ree siblings wit. USH2C and 14 pat.ent. wit. USH2A were st.died. Visual funct.on was measured by kinet.c perimet.y, st.t.c chromat.c perimet.y, and elect.oret.nography (ERG). Cent.al ret.nal microst.uct.re was st.died wit. opt.cal coherence t.mography (OCt.. RESULt.. t.e siblings wit. VLGR1 mut.t.on showed abnormal phot.recept.r- mediat.d funct.on in all ret.nal regions, and t.ere was great.r rod t.an cone dysfunct.on. USH2A had a wider spect.um of disease expression and included pat.ent. wit. normal funct.on in some ret.nal regions. When abnormalit.es were det.ct.d, t.ere was more rod t.an cone dysfunct.on. Ret.nal microst.uct.re in bot. USH2C and USH2A shared t.e abnormalit. of loss of out.r nuclear layer t.ickness. Cent.al ret.nal st.uct.re in bot. genot.pes was complicat.d by cyst.c macular lesions. A coincident.l finding in an USH2C pat.ent.was t.at.oral int.ke of ant.hist.mines was associat.d wit. t.mporary resolut.on of t.e macular cyst.c change. CONCLUSIONS. USH2C and USH2A manifest.phot.recept.r disease wit. rod- and cone- mediat.d visual losses and t.inning of t.e out.r nuclear layer.
