Liver meta.ta.is is a.norma. result in Ehrlich a.cites Ca.cinoma.Cell (Ea.) infected mice. a.pa.tia.ly purified protein with Superoxide Dismuta.e (SOD)-like a.tivity extra.ted from lea.es of Ra.hnus sa.ivus wa. tested for its a.ility to down regula.e liver meta.ta.is of Ehrlich a.cites Ca.cinoma.Cell (Ea.) intra.eritonea.ly impla.ted in a.bino mice. Sixty a.bino mice were divided equa.ly into 4 groups. Group I mice (G1 control) were trea.ed with physiologic sa.ine solution for 7 da.s. Group 2 mice (G2) were injected with the pa.tia.ly purified protein. Group 3 mice (G3) were intra.eritonea.ly inocula.ed with Ea. cells a.d trea.ed with the pa.tia.ly purified protein. Group 4 mice (G4) were inocula.ed Ea. cells a.d trea.ed with physiologic sa.ine solution. The results showed a.disturba.ce in liver functions. This disturba.ce wa. observed a. a.reduction in the va.ues of serum a.bumin, hemoglobin, tota. counts of erythrocytes a.d pla.elets, tota. lipids in liver tissues, erythrocytes SOD a.tivity, serum glucose, reduced gluta.hione (GSH) a.d the tra.e elements (Fe, Mn, Zn, a.d Cu) contents in liver a.d spleen tissues a. well a. the eleva.ion of serum tra.sa.ina.es a.tivities, the levels of ma.ondia.dehyde in blood, DNa.a.d RNa.of liver tissues in the infected mice (G4). On the other ha.d, in G3, a.ter trea.ment with the pa.tia. purified protein a.l these pa.a.eters restored their norma. va.ues a.d beca.e nea. from the norma. group (GI). Moreover, the protein showed no toxicity towa.ds the mice a. shown in G2. It could be concluded tha. a.pa.tia.ly purified protein with Superoxide Dismuta.e (SOD)-like a.tivity extra.ted from lea.es of Ra.hnus sa.ivus a. a.na.ure source ha. a.promised future in controlling liver meta.ta.is.

Ba.kground: The trea.ment of bra.n meta.ta.es with ra.iothera.y ha. shifted to the use of Stereota.tic Ra.io-surgery (SRS). The technica. issue of expa.ding the trea.ment volume a.ound the Gross Tumor Volume (GTV) is a.current deba.e. Ra.iothera.y centers use va.ia.le GTV-PTV ma.gins, ra.ging from one to 2 mm.

The V12 of the bra.n significa.tly va.ied a. a.function of PTV ma.gin (p = 0.000). The ta.get covera.e a.d pla. qua.ity indices were not significa.tly different. The Peel volume dosimetric a.a.ysis showed tha. the mea. dose wa. significa.tly higher in the nea.by norma. bra.n tissue: Peel1 (p = 0.022) a.d Peel 2 (p = 0.013). Conclusion: a.cording to our dosimetric a.a.ysis, expa.ding the GTV into a.PTV by 1 mm ma.gin is more convenient tha. 2 mm.
