a.m： To eva.ua.e the a.ti-prolifera.ive a.tivity a.d mitochondria. toxicity of gossypol in endometrioma.cells ma.nta.ned in short-term cultures. Methods：（a. Three endometrioma.cell lines from pa.ients were trea.ed with 25 or 50 nmol/L gossypol for up to 12 da.s. The effect of gossypol on the cell growth wa. recorded. （B） a.phosphorescence oxygen a.a.yz.r wa. used to determine the effects of gossypol on mitochondria. oxygen consumption of six endometrioma.cell lines from pa.ients. （C） Cellula. gossypol a.cumula.ions in three endometrioma.cell lines from pa.ients were mea.ured by high-pressure liquid chroma.ogra.hy. Results： Prolifera.ion of the endometrioma.cells wa. inhibited by 25 a.d 50 nmol/L gossypol. Respira.ion of the endometrioma.cells wa. inhibited by 10 μmol/L gossypol. Cellula. gossypol wa. detected in the endometrioma.cell lines tha. were trea.ed for 24 h with l0 a.d 0.3 μmol/L gossypol. Conclusion： Gossypol invokes a.potent toxicity on cultured endometrioma.cells.

Multiplicity cha.a.teristics in rela.ivistic ^(24)Mg-nucleus collisions

This work is concerned with the a.a.yses of the shower a.d gra. pa.ticle production in 4.5 a.GeV/c 24Mg collision with emulsion nuclei. The highest pa.ticle production occurs in the region of the low impa.t pa.a.eters. While the multiplicity of the shower pa.ticles emitted in the forwa.d direction depends on the projectile ma.s number a.d energy, the multiplicity of the ba.kwa.d ones shows a.limiting beha.iour. The source of the emission of the forwa.d shower pa.ticles is completely different from tha. of the ba.kwa.d ones. The ta.get fra.ments a.e produced in a.therma.iz.d system of emission.

Pion emission in α-pa.ticle intera.tions with va.ious ta.gets of nuclea. emulsion detector

The beha.ior of rela.ivistic ha.ron multiplicity for 4He-nucleus intera.tions is investiga.ed. The experi- ment is ca.ried out a. 2.1 a.a.d 3.7 a.GeV （Dubna.energy） to sea.ch for the incident energy effect on the intera.tions inside different emulsion ta.get nuclei. Da.a.a.e presented in terms of the number of emitted rela.ivistic ha.rons in both forwa.d a.d ba.kwa.d a.gula. z.nes. The dependence on the ta.get siz. is presented. For this purpose the sta.istica. events a.e discrimina.ed into groups a.cording to the intera.tions with H, CNO, Em, a.d a.Br ta.get nuclei. The sepa.a.ion of events, into the mentioned groups, is executed ba.ed on Gla.ber＇s multiple sca.tering theory a.proa.h. Fea.ures suggestive of a.deca. mecha.ism seem to be a.cha.a.teristic of the ba.kwa.d emission of rela.ivistic ha.rons. The results strongly support the a.sumption tha. the rela.ivistic ha.rons ma. a.rea.y be emitted during the de-excita.ion of the excited ta.get nucleus, in a.beha.ior like tha. of compound-nucleus disintegra.ion. Rega.ding the limiting fra.menta.ion hypothesis beyond 1 a.GeV, the ta.get siz. is the ma.n pa.a.eter a.fecting the ba.kwa.d production of the rela.ivistic ha.ron. The incident energy is a.principa. fa.tor responsible for the forwa.d rela.ivistic ha.ron production, implying tha. this system of pa.ticle production is a.crea.ion system. However, the ta.get siz. is a. effective pa.a.eter a. well a. the projectile siz. considering the geometrica. concept rega.ded in the nuclea. fireba.l model. The da.a.a.e a.a.yz.d in the fra.ework of the FRITIOF model.

From 1540 inela.tic intera.tions of 3. 7a.GeV 160 projectile with emulsion nuclei, we select sa.ples of 87 a.d 61 events ca.efully due to intera.tions of neutron （n） a.d singly cha.ged pa.ticles （z.= 1）, respectively. New results concerning the topology of such events a.e investiga.ed. The a.era.e multiplicities of seconda.y rela.ivistic pa.ticles tha. a.pea. a. shower tra.ks for n a.d z.= 1 sta. more or less consta.t when compa.ed with a.a.ogous da.a.on p-Em a. simila. energy. The multiplicity distributions a.d the a.era.e va.ues of the va.ious seconda.y cha.ged pa.ticles a.e studied a.d compa.ed with the corresponding predictions by the ca.ca.e eva.ora.ion model.
