The foreign intra-Arab trade is.an es.ential tool and important input in order to achieve an important Arab economic integration. However, in s.ite of the efforts.for the Liberation of the Arab Trade and Development, the fact indicates.the modes. rate of the foreign intra-Arab trade to the foreign total Arab trade with the world, as.it does.not exceed that percentage to 10.9% in year 2013. The pres.nt res.arch is.aimed at meas.ring the efficiency of the total foreign intra-Arab trade during the period (1990-2010). Where, it has.been increas.d s.arply, as.value of the total foreign intra-Arab trade increas.s.annually by about 12.6%. s.udi Arabia and United Arab Emirates.are cons.dered the mos. important contributors.of the total foreign intra-Arab trade, and a category of manufacturing has.dominated the larges. relative importance in average value of total Arab trade, which has.accounted to 50.8%. Followed by category, metal fuel and other metals.are accounted by about 25.3% and there is.lower overall contribution to the foreign intra-Arab trade in the total foreign trade of Arab and its.amount has.increas.d by 10.58%. Therefore, it is.recommended to further coordination among the Arab s.ates.in the areas.of production and s.ecialization in economic production. This.is.als. recommended to es.ablis. the s.ecialized department for greater Arab free trade area in every Arab country in addition to accelerate the es.ablis.ment of a cus.oms.union.

Background and Objective: The liver is.res.ons.ble for metabolis. and detoxification of the mos. of components.that enter the body. Once the liver became injured, its.efficient treatment with famous.chemical drugs.was.limited. Therefore, interes. concerned the us. of alternative medicines.for the treatment of hepatic dis.as. has.been aris.n. The pres.nt s.udy was.aimed to inves.igate the therapeutic effect of the two types.of s.em cells.agains. chromos.mal aberrations.in bone marrow (BM) cells.of rats.treated with carbon tetrachloride (CCl4). Des.gn and Method: BM-derived mes.nchymal s.em cells.(Ms.s. were is.lated and propagated in culture for 2 weeks.and were characterized morphologically. Human umbilical cord blood (UCB) cells.were obtained after full-term caes.rean delivery from healthy donors. Low-dens.ty mononuclear cells.were s.parated over Ficoll-Paque, and CD34+ hematopoietic cells.were is.lated us.ng a magnetic cell s.rter. Rats.were divided into 4 groups. control, CCl4, CCl4 plus.Ms., and CCl4 plus.CD34+. Liver tis.ue was.examined his.opathologically for all groups. Res.lts. The res.lts.of the pres.nt s.udy indicated a s.gnificant increas. (p s.s.with different types.of chromos.mal aberrations.in CCl4 group. Treatment of the animals.with BM-Ms.s.and UCB-CD34+ cells.improved both genotoxicity and his.opathological changes.induced by CCl4.
