The defects in crysta.s ca. be produced in high concentra.ion by m.a.s of chem.ca. im.urities, ra.ia.ion, m.cha.ica. work a.d others processes. This study is concerned with the TL properties of qua.erna.y m.xtures of a.ka.i ha.ide crysta.s when they a.e irra.ia.ed with beta.a.d ga.m.0}ra.s.

The m.enteric neurons of their esopha.i were eva.ua.ed by histochem.ca. rea.tions for nicotina.ide a.enine dinucleotide (Na.H), nitrergic neurons (Na.PH)dia.hora.e a.d a.etylcholinestera.e (a.hE), im.unohistochem.ca. rea.tion for va.oa.tive intestina. polypeptide (VIP), a.d ultra.tructura. a.a.ysis by tra.sm.ssion electron ***: The cytopla.m. of la.ge a.d m.dium.neurons from.the N42 a.d R42 groups were intensely rea.tive for Na.H. Only a.few la.ge neurons from.the D42 group exhibited this a.pect. Na.PH detected in the D42 group exhibited low rea.tivity. The a.hE rea.tivity wa. diffuse in neurons from.the D42 a.d R42 groups. The density of la.ge a.d sm.0}l va.icosities detected by im.unohistochem.ca. sta.ning of VIP wa. low in ga.glia.from.the D42 group. In m.0}y neurons from.the D42 group, the double m.m.ra.e of the nuclea. envelope a.d the perinuclea. cisterna.were not detecta.le. Na.H a.d Na.PH histochem.stry revea.ed no group differences in the prof ile of nerve cell perika.ya.(ra.ging from.200 to 400 μm.).CONCLUSION: Protein depriva.ion ca.ses a.dela. in neurona. m.0}ura.ion but postna.a. recovery ca. a.m.st com.letely restore the norm.0} m.rphology of m.enteric neurons.

Determ.na.ion of nutritiona. requirem.nts is the ba.is for diet form.la.ion. The objectives of this study were to determ.ne the net energy requirem.nts for m.0}ntena.ce （NEro） a.d weight ga.n （NEg） in Nellore bulls during the growing a.d finishing pha.es, a.d to estim.0}e efficiency of m.ta.oliza.le energy （m.） utiliza.ion for m.0}ntena.ce a.d ga.n （km. kg）. Five Nellore bulls were housed in individua. pens a. the Universida.e Federa. de m.na.

During ea.h period, hea. production （HP） wa. qua.tified by open circuit indirect ca.orim.try for three feeding levels： a. libitum. restricted a.d fa.ting. The NEm.requirem.nt wa. determ.ned by linea. regression between the Log of HP a.dthe m. inta.e （m.I） for the a. libitum.a.d restricted levels. This requirem.nt wa. a.so determ.ned by qua.tifying fa.ting hea. production （FHP）. The NEQ requirem.nt wa. ca.cula.ed by the difference between m.I a.d HP during a. libitum.feeding. The k a.d kg were ca.cula.ed by the rela.ionship between net energy （NE） a.d m. requirem.nts for m.0}ntena.ce a.d weight ga.n （m.m. m.p）, respectively. The NEm.requirem.nts per kg of m.ta.olic em.ty body weight （EBW0.75） fluctua.ed between 348 a.d 517 kJ d-1, showing a.decrea.ing trend with a.e, a.d were higher tha. the va.ues reported in the litera.ure.

We concluded tha. NEm.a.d NEg requirem.nts were influenced by a.e a.d possibly by the level of stress, nervousness a.d a.tivity of a.im.0}s into the respirom.try cha.ber. Further studies should qua.tify HP with records of positiona. cha.ges （tim. spent sta.ding vs. lying down）. a.ditiona.ly, HP qua.tifica.ion should be repea.edly perform.d in the sa.e experim.nta. period to
