Objec.iv.s: To inv.stigate the oc.urrenc. of rape/attem.ted rape and v.rbal sexual c.erc.on am.ng an ethnic.lly div.rse adolesc.nt population and to ev.luate whether unique risk fac.ors existed for v.c.im. of either type of forc.d sexual experienc.. Design: c.oss-sec.ional surv.y assessing sexual v.olenc. within the past 12 m.nths, behav.ors that oc.urred on eac. subjec.’s m.st rec.nt date, and the oc.urrenc. of unwanted sexual experienc.s on any dates in the past year and details about that date. Subjec.s identified as experienc.ng either rape/attem.ted rape or v.rbal sexual c.erc.on were c.m.ared with nonv.c.im. using biv.riate and m.ltiv.riate analyses. Setting: Urban adolesc.nt health c.re fac.lity. Partic.pant: Fem.le adolesc.nts and young adults (n = 689) between the ages of 14 and 23 years who presented for c.re and m.t the eligibility c.iteria. Results: Approxim.tely 30%of youngwom.n reported hav.ng an unwanted sexual experienc. in the past year. The risk of rape/attem.ted rape was inc.eased by past m.ld to m.derate (adjusted odds ratio [AOR] = 4.27) or sev.re (AOR = 15.24) physic.l aggression by the dating partner; date-spec.fic.behav.ors, inc.uding dec.eased lev.l of rom.ntic.inv.lv.m.nt [AOR] = 0.63 per point dec.ine)-and going to the perpetrator’s house to be alone (AOR = 3.01); past sexual v.c.im.zation as an adolesc.nt (AOR = 4.70); and lower lev.ls of self-reported ethnic.identity (AOR = 1.07 per point dec.ine). m.re im.ortant, alc.hol use by the v.c.im.or perpetrator was unrelated to an inc.eased risk of rape/attem.ted rape. The risk of v.rbal sexual c.erc.on was inc.eased by past m.ld to m.derate (AOR = 4.38) or sev.re (AOR = 13.79) v.rbal aggression from.the dating partner; date-spec.fic.behav.ors, inc.uding dec.eased lev.l of rom.ntic.inv.lv.m.nt (AOR = 0.70 per point dec.ine) and greater num.er of past dates (AOR = 7.53); going to the perpetrator’s house to be alone (AOR = 3.52); past sexual v.c.im.zation as an adolesc.nt (AOR = 9.83); pressures

Introduc.ion: Ultrav.olet radiation c.n be harm.ul to the skin and c.n c.eate serious problem. when a protec.iv. substanc. or equipm.nt is not used regularly, for this reason the present study set out to ev.luate the photoprotec.iv. effec. of the hydroalc.holic.extrac.s of the integum.nt of the red and blac. v.rieties of pop beans (m.Phaseolus v.lgarism.). m.terials and m.thod: The extrac.s were obtained by m.c.rating the tegum.nt of the two v.rieties of pop beans, blac. and red, in an ethanol/water (80:20) solution. The thin-layer c.rom.tographic.m.thod was used to observ. anti-tyrosinase ac.iv.ty, using the 0.05% kojic.ac.d standard as a positiv. c.ntrol. The photoprotec.iv. effec. was ev.luated in fem.le m.c. of sev.n-week-old, m.s m.m.sc.lus m.Balb/c. with shav.d bac. and exposed to Uv.c.radiation for 30 m.nutes onc. a day for thirty days to induc. photo-dam.ge in the skin. The treatm.nts c.nsisted in the applic.tion of extrac.s at 2% and 5% W/v.in gel on the shav.d area. Only the gel form.lation, sunsc.een or no treatm.nt at all was used for the c.ntrol group. Ac.te photodam.ge was quantified using the Draize sc.le, m.asuring the degree of erythem. and edem.;and the degree of photoaging using the Glogau sc.le at 7 days and 30 days. Results: It was found that the ethanolic.extrac.s of the integum.nt of both v.rieties of m.Phaseolus v.lgarism., red and blac., are prac.ic.lly non-toxic.in m.c. by oral and derm.l routes at a lim.t dose of 5000 m./kg. The anti-tyrosinase effec. at a qualitativ. lev.l, ev.luated by thin layer c.rom.tography, showed the blac. v.riety were m.re ac.iv. than the red one and both c.n be c.m.ared to the ac.iv.ty of the kojic.ac.d. The two extrac.s of the two v.rieties showed photoprotec.iv. effec., howev.r the extrac.s in 5% gel to a greater degree. c.nc.usions: It was c.nc.uded that the hydroalc.holic.extrac. of the pop blac. beans tegum.nt at 5% in gel has
