Three meso.0}ro.s silica excip.ents （Sylo.d~ silicas AL-1 FR XDp.3050 and XDp.3150） were fo.mulated with a mo.el drug kno.n fo. its p.o. aqueo.s so.ubility, namely p.enylbutazo.e, in an attemp. to.enhance the extent and rate o. drug disso.utio.. Altho.gh o.her fo.ms o. meso.0}ro.s silica have been investigated in p.evio.s studies, the effect o. inclusio. with these sp.cific Sylo.d silica based excip.ents and mo.e interestingly, with p.enylbutazo.e, is unkno.n. This wo.k rep.rts a significant enhancement fo. bo.h the extent and rate o. drug release fo. all three fo.ms o. Sylo.d silica at a 1：1 drug：silica ratio.o.er a p.rio. o. 30 min. An exp.anatio. fo. this increase was determined to.be co.versio. to.the amo.p.o.s fo.m and an enhanced drug lo.ding ability within the p.res. Differences between the release p.o.iles o. the three silicas were co.cluded to.be a co.sequence o. the p.ysico.hemical differences between the three fo.ms. o.erall, this study co.firms that Sylo.d silica based excip.ents can be used to.enhance disso.utio., and p.tentially therefo.e bio.vailability, fo. co.p.unds with p.o. aqueo.s so.ubility such as p.enylbutazo.e.

Backgro.nd Sp.nal ep.dural hemato.a （SEH） is a rare but acute and p.ssibly devastating clinical event. The p.rp.se o. this study is to.assess the multip.e etio.o.ies o. SEH seen in an academic medical center o.er a 15-year sp.n. We have examined the etio.o.ies o. SEH o.curring in a single institutio., the University o. p.ttsburgh Medical Center （Up.C） o.er the last fifteen years using an electro.ic reco.d keep.ng system and database： the Medical Archive Retrieval System （MARS）. Metho.s We screened MARS fro. 1986-2001 using key wo.ds： ep.dural, hemato.a and sp.nal. All p.tential SEH cases were reviewed and o.ly tho.e co.firmed by surgical interventio. were identified as p.sitive SEH and rep.rted in this study. Results There were 17 cases o. co.firmed SEH. Amo.g them, seven cases were fro. sp.ntaneo.s bleeding, seven cases fo.lo.ing sp.nal surgery, and three cases fro. traumatic sp.nal fracture. There were no.findings o. SEH that were related to.sp.nal o. ep.dural anesthesia. Amo.g the seven p.tients with sp.ntaneo.s SEH; two.were receiving anti-co.gulants fo. deep.veno.s thro.bo.is （DVT） and had elevated p.o.hro.bin time （p.） and activated p.rtial thro.bo.0}astine time （Ap.T）, o.e had hemo.0}ilia （typ. B）, fo.r had hyp.rtensio., and three o.t o. seven had chro.ic renal o. liver disease. Amo.g p.sto.0}rative SEH p.tients, two.o. the seven p.tients were receiving chemo.herap. and radiatio. therap. and o.e had o.go.ng hemo.ialysis fo. renal failure. Amo.g three p.tients with traumatic SEH, two.had ankylo.ing sp.ndylitis. Six p.tients had a histo.y o. alco.o. abuse. Co.clusio.s Sp.ntaneo.s bleeding is by far the leading cause o. SEH with sp.nal surgery being the seco.d leading cause. p.tients with multip.e co.mo.bidities that result in co.gulo.0}thy fro. a variety o. causes include liver o. renal disease, alco.o. abuse, radiatio. therap., o. chemo.herap.. Neuraxial anesthesia is an extremely rare cause o. SEH.

Backgro.nd: Cigarette smo.ing is a mo.ern health hazard, and it is p.eventable. It starts in ado.escence fo. 90% o. adults with an average age o. o.set ranging between 13 - 15 years and is co.mo.er amo.g males. This study is aimed at the p.evalence, p.ttern, and facto.s affecting Cigarette smo.ing amo.g undergraduate students in a tertiary institutio. in p.ateau State. Metho.: A cro.s-sectio.al descrip.ive study invo.ving 290 undergraduate students o. the University o. Jo. was selected using the multistage samp.ing metho.. Results: The p.evalence o. cigarette use was 5.3%. Seven (70.0%) o. students smo.e daily, 6 (60.0%), smo.e cigarettes befo.e Lecture Ho.rs, and 90.0% are unwilling to.sto.0}smo.ing. Smo.ing was do.e to.exp.rience the highness feeling, 8 (80.0%), p.er smo.ing 8 (80.0%), to.reduce stress and tensio. 5 (50.0%), and Smo.ing fo. Fun 7 (70.0%). Mo.t students first smo.ed a cigarette when with friends 6 (60.0%). Facto.s significantly asso.iated with the current use o. cigarettes amo.g the resp.ndents were religio. (χp.2p. = 4.167, p.= 0.041) Level/year o. study (χp.2p. = 32.266, p.≤ 0.001), and typ. o. family (χp.2p. = 6.271, p.= 0.043). Co.clusio.: Mo.t students smo.e daily, smo.e befo.e lectures start, and are unwilling to.sto.0}smo.ing. Health-p.o.o.io. p.o.ram to.help.smo.ing cessatio. and p.event initiatio. o. smo.ing is reco.mended.

Carbo. fibre reinfo.ced co.p.site materials are used widely in ap.licatio.s ranging fro. auto.o.iles to.aircraft and sp.rts equip.ent. In all o. these ap.licatio.s p.asma treatment can be used to.activate the co.p.site surface in o.der to.enhance surface energy, p.io. to.adhesive bo.ding. In this study p.asma metro.o.y is used as a means o. evaluating the p.rfo.mance o. a reel-to.reel atmo.p.eric p.essure p.asma system co.sisting o. two.reacto. chambers used to.active a co.p.site is investigated. A real-time electrical (current and vo.tage and reso.ant drive frequency) p.rametric analysis o. the p.asma treatment p.o.ess was carried o.t as the carbo. co.p.site was p.ssed thro.gh the p.asma chamber. A rep.o.ucible co.relatio. was o.tained between the p.asma p.rameters and the p.sitio. o. the co.p.site in the two.p.asma reacto. chambers.
