alkalozALKALOZ (az lot. alcali – ishqor), ikhtiloli muvozanati kislotayu ishqorho dar organizm, ki hangomi on miqdori asosho meafzoyad. A. jubroni va gayrijubroni meshavad. Hangomi A.-i jubroni pH-i khun mutadil (7,35 – 7,45) ast; dar asnoi A.-i gayrijubroni pH az 7,45 ziyod ast, ki sababi in bartari hosil kardani asosho va illati mekhanizmhoi khimiyaviyu fiziologii tanzimi muvozinati kislotayu ishqorho meboshad. A. vobasta ba paydoish gazi, gayrigazi va omekhta meshavad. A. – i g a z i dar natijai giperventilyatsiyai shush ba vujud meoyad. Sababi giperventilyatsiyai shush bemorihoi mayna (ensefalitho, omos va g.), tasiri moddahoi khimiyavi va doruho ba markazi nafasgiri, baland shudani harorati badan, khunravihoi shadid va g. meboshand. A.-i gayrigazi se nav – ikhroji, ekzogeni va mubodilavi meshavad. A.-i ikhroji dar natijai is- temoli durudarozi doruhoi peshobron, baze bemorihoi gurda, gadudhoi usorai dokhili, seraraqi ba vujud meoyad. Sababi A.-i ekzogeni barziyod vorid shudani bi- karbonati natriy ast. A.-i mubodilavi hangomi baze bemoriho, ki boisi ikhti- loli mubodilai elektrolitho meshavand, sar mezanad (mas., dar mavridi gemoliz, rakhit, badi jarrohi va g.). A.-i omekhta dar surati oseb yoftani mayna, ki bo damkutahi va qay jarayon megirad, ba vuqu mepayvandad. Hangomi A. harakati khun khalaldor, fishori sharayon past meshavad, faoliyati rudaho va markazi nafas taboh megardad. Dar natijai A.-i gazi faoliyati zehni sust shuda, sar charkh mezanad, bemor az hush meravad. Tabobati A. ba raf namudani sababhoi on nigaronida shuda- ast (istifodai mahlulhoi khloridi ammo- niy, kaliy, kaltsiy, isulin va g.).
