CHEMICO-GELATINOUS INJECTION FOR ANATOMICAL PREPARATIONS.

Subcutaneous Injection of Oils or Oily Preparations

The anatomical approach in stellate ganglion injection.

T H E sympathetic outflow to the head and neck and the greater part of that to the upper limbs passes on each side through the relatively small confines of the stellate ganglion and is here subject to interruption by stellate ganglion block. This block will cut off all efferent sympathetic impulses to the head and neck and most, if not all, of those to the upper limb and may be of value for exa...

On a New Method of Preserving Anatomical Preparations

gaged in making trial of a method, which I believe to be new, of preserving anatomical preparations, the advantages attending which have exceeded my most sanguine expectations. Its principal advantages consist, first, in its great cheapness ; secondly, in the durability of its preservative power; and, thirdly, in the clear and instructive manner in which it displays the minute structure of text...

Flow-Injection Iodimetric Determination of Captopril in Pharmaceutical Preparations

Um procedimento simples, rápido e de baixo custo é descrito para a determinação de captopril em preparações farmacêuticas. O procedimento é baseado em um sistema de análises por injeção em fluxo explorando a formação em linha de triiodeto, o qual é consumido na presença do analito gerando um sinal transiente. Resposta linear foi observada até 200 μmol L com limite de detecção de 1,0 μmol L (99,...

Flow-injection and sequential-injection determinations of paracetamol in pharmaceutical preparations using nitrosation reaction.

A simple FI and two different SI systems have been investigated for the determination of paracetamol by employing a simple reagent for a nitrosation reaction. It is based on the on-line nitrosation of paracetamol with sodium nitrite in an acidic medium. The formed nitroso derivative species reacts further with sodium hydroxide to convert it to a more stable compound. The yellow product is conti...
