MEDIAN LETHAL DOSE SÖZCÜĞÜ İNGILIZCE DİLİNDE NE ANLAMA GELİR?
Ortanca öldürücü doz
Toksikolojide, bir toksinin, radyasyonun veya patojenin medyan ölümcül dozu olan LD50, LC50 veya LCt50, test edilen bir popülasyonun üyelerinin yarısını belirli bir test süresinden sonra öldürmek için gereken dozdur. LD50 rakamları, bir maddenin akut toksisitesinin genel bir göstergesi olarak sıklıkla kullanılır. Test J.W. tarafından hazırlandı. Semilethal doz terimi, özellikle İngilizce dışındaki metinlerden çevirilerde aynı anlamda kullanılıyor, fakat aynı zamanda sublethal bir dozu da ifade edebiliyor; Bu belirsizlik yüzünden genellikle engellenir. LD50 genellikle laboratuar fareleri gibi hayvanlar üzerindeki testlerle belirlenir. 2011'de ABD Gıda ve İlaç İdaresi, hayvan deneyleri olmaksızın BOTOX kozmetik ilaçlarını test etmek için LD50'ye alternatif yöntemler onayladı.
