i.troducti.n: Vascular endotheli.l growth factor-C (VEGF-C) i. the pri.0}ry lym.hangi.geni. factor that sti.0}lates lym.hangi.genesi. by si.nali.g vi. speci.i. receptor, vascular endotheli.l growth factor receptor 3 (VEGFR3). Thi. study was conducted to evaluate the change i. the level of VEGF-C before and after autologous bone m.rrow m.nonuclear cell transplantati.n for treatm.nt of Lower li.0} lym.hedem.. Pati.nt and m.thods: Forty pati.nts wi.h lower li.0} lym.hedem. were di.i.ed i.to two groups. Group i.i.cluded 20 pati.nts wi.h chroni. lower li.0} lym.hedem. who underwent autologous bone m.rrow m.nonuclear cell transplantati.n. Group i. i.cluded 20 pati.nts wi.h chroni. lower li.0} lym.hedem. who were exposed only to com.ressi.n therapy as a control group. VEGF-C level i. the di.eased li.0}s was m.asured i. both groups at the begi.ni.g of the study then 3 and 6 m.nths respecti.ely. Results: Group i.i.cluded 20 pati.nts, 8 pati.nts were m.le (40%) and 12 pati.nts were fem.les (60%) wi.h m.an age 29.5 ± 12.15 whi.e group i. i.cluded 20, 10 pati.nts were m.le (50%) and 10 pati.nts were fem.les (50%) wi.h m.an age 39.5 ± 11.5. i. group i. the speci.0}ns were taken at 3 and 6 m.nths after transplantati.n showed a m.rked decrease i. the VEGF-C level wi.h stati.ti.ally si.ni.i.ant p value, 0.02 and 0.001 respecti.ely. i. group i. the level of VEGF-C after com.ressi.n therapy alone at 3 and 6 m.nths i.terval showed fluctuati.n wi.h stati.ti.ally non-si.ni.i.ant p value, 0.64 and 0.55 respecti.ely. Conclusi.n: VEGF-C i. essenti.l for regulati.n of lym.hangi.genesi.. The level of VEGF-C was found elevated i. pati.nts wi.h lym.hedem. and decrease after autologous m.nonuclear bone m.rrow cells, however these results were stati.ally non-si.ni.i.ant.

Sudan’s sem.-ari. land consti.utes a di.ersi.y of habi.ats, speci.s, and geneti. resources of hi.h ecologi.al and econom.c value. Thi. di.ersi.y i. gradually degradi.g due to cli.0}te change and hum.n m.suse. Bi.di.ersi.y m.ni.ori.g began i. Sudan before i.dependence when a consi.erable num.er of flora and fauna speci.s were i.enti.i.d. i.sects were am.ng the i.enti.i.d fauna where m.ny orders, fam.li.s, and speci.s were classi.i.d especi.lly those of econom.c, m.di.i.al, and veteri.ary i.0}ortance. Bom.yli.dae or bee fli.s are consi.ered nati.e to Afri.an countri.s and confi.ed to the sem.-ari. ecosystem.as polli.ators of hi.her plants. The bee fly, Eurycarenus di.hopti.us recorded from.these ecosystem., has gai.ed li.tle attenti.n, and m.ager data on i.s bi.logy and reproducti.n have been publi.hed. Adults of thi. i.sect are nectar feeders, and fem.les also feed on pollen grai.s whi.e larvae are parasi.oi.s on certai. i.sects. Thi. study was conducted i. three Sudanese states that li. wi.hi. the sem.-ari. ecosystem.Khartoum. Gezi.a, and North Kordofan. Fi.ld surveys were conducted i. these states and i.sect fauna was obtai.ed and i.enti.i.d. Bee fly speci.0}ns were collected from.North Kordofan usi.g the butterfly net m.thod. The speci.0}ns were then preserved and sent to the Agri.ultural Research Corporati.n ARC i.

Allelopathi. effects of Eucalyptus cam.ldulensi. Dehnh. were confi.m.d i. Petri.di.h and pot experi.0}nts i. our previ.us studi.s. However, the degree to whi.h such effects under controlled experi.0}nts exi.t i. m.re com.lex ecologi.al setti.gs rem.i.s to be tested. Thus, the present study was carri.d out by i.corporati.g di.ferent proporti.ns of ground li.ter of E. cam.ldulensi. i. soi.. The growth of three agri.ultural crops: falen(Vi.na ungui.ulata(L.)

The extent of the effects was dependent on the proporti.n of leaf li.ter, the speci.s and the type of trai.s. i. contrast to shoot growth, the effect on root growth was m.re severe. No effect on germ.nati.n was found wi.h the agri.ulture crops whi.e the two tree speci.s showed reduced germ.nati.n. The effect was greater i. the presence of hi.her proporti.ns of leaf li.ter m.xed i. soi. whi.e i. som. cases lower proporti.ns sti.0}lated growth.
