Dental Amalgams

An iodized sodium hydroxide solution. is suitable as an etch for conventional amalgams. In diluted form and followed by sodium thiosulfate solution, this may be used on dispersed phase, ternary and quaternary alloy amalgams for clearer results than with the cyanide method. Alternative etches are given for ternary-quaternary materials.

The sodium salt of 4-amino-3-nitrobenzenesulfonic acid (O-nitroaniline-p-sulfonic acid) has been prepared by the action of dilute sodium hydroxide solution on ethyl [(4-chlorosulfonyl-2-nitro)- phenyllcarbamate. Central to this synthesis is the finding that the N-ethoxycarbonyl group, when located ortho to a nitro group (but not to a bromo group), is readily removed by dilute sodium hydroxide solution.

Avaliou-se a produção de celulases e xilanase de Aspergillus niger IZ9, crescido sobre bagaço de cana, quimicamente tratado, como substrato. Os tratamentos foram: solução de hidróxido de sódio a 4%, e solução de hidróxido de sódio a 4%, ácido fosfórico p.a. e vapor. A produção das enzimas celulolíticas (celulase total, endoglicanase e ­glicosidase) e xilanase foi observada nos bagaços tratados e nãotratado. O tratamento com solução de hidróxido de sódio a 4% promoveu maior indução de síntese da maioria das enzimas, com exceção de ­glicosidase, a qual apresentou produção semelhante para os bagaços tratados quimicamente. Abstract It was evaluated the production of cellulases and xylanase by Aspergillus niger IZ09 grown in a substrate consisted of chemically treated sugarcane bagasse. The treatments were: 4% sodium hydroxide solution and 4% sodium hydroxide solution, phosphoric acid and steam. The production of the cellulolytic enzymes (total cellulase, endoglycanase and B.CEPPA, Curitiba, v. 18, n. 1, jan./jun.2000 67 ­glucosidase) and xylanase was observed in the treated and nontreated bagasses. The treatment with 4% sodium hydroxide solution promoted a greater induction of the synthesis of the majority of the enzymes, with exception of ­glucosidase, which showed similar production for both chemically treated bagasses.
