Algebra without Zorn is lemma

One can not get also much in abstract algebra prior to running into Zorn is Lemma. As an example, it is made use of in the evidence that every nonzero ring has a topmost perfect. Nonetheless, it appears that if we limit our emphasis to Noetherian rings, we can usually stay clear of Zorn is lemma. Just how much could a growth of the concept for simply Noetherian rings go? When do non - Noetherian rings show up in a crucial means for which there is no Noetherian analog? As an example, Artin is evidence that every area has an algebraic closure makes use of Zorn is lemma. Exists an evidence of this theory (or some Zorn - much less variation of this theory) that prevents it?
