Preliminary interpretive susceptibility testing criteria for FK-037 with 30-microgram disks.
FK-037, a new parenteral cephalosporin, was tested against 483 organisms from clinical infections to establish preliminary susceptibility testing criteria with 30-micrograms disks. The proposed breakpoint zone diameters were > or = 17 mm (MIC correlate, < or = 8 micrograms/ml) for the susceptible category and < or = 13 mm (MIC correlate, > or = 32 micrograms/ml) for the resistant category. Thes...
متن کاملSpectrophotometric Determination of Microgram Quantities of Copper in Biologic Materials.
A procedurefor the determination of microgramquantities of copper in biologicmaterial is described. The sample is wet-ashed with a nitric acid-perchloric acid mixture. The copper is extracted from an alkaline solutionof the ash with a solutionof diphenylcarbazide in benzene. Absorbanceof the red complex is read at 540 m1&. The copperin as little as0.5 ml. of serum can be determined and the meth...
متن کاملSimple Colorimetric Assay for Microgram Determination of Bromhexine Hydrochloride with Mbth and 2, 2’ Bipyridyl
The present work describes two new spectrophotometric methods for the determination of bromhexine hydrochloride in bulk and formulations. Method A is based on the reduction of Fe into Fe by the drug followed by the complex formation of Fe with 2, 2’ bipyridyl to form cherry red colored chromogen having maximum absorbance at 510nm and Method B is based on oxidation of 3-methylbenzothiazolinone-2...
متن کاملDetermination of Microgram Quantities of Inorganic Boron in Mammalian Specimens.
A method is presented for estimation of inorganic boron in mammalian tissues, blood, cerebrospinal fluid, and urine. The procedure is simple and rapid, qualifying it particularly to meet needs in clinical chemistry. The mammalian tissues are first enzymatically digested and extracted; then the deproteinized extract is allowed to react with quinalizarin in concentrated sulfuric acid. The intensi...
متن کاملMucin clots from microgram amounts of hyaluronic acid.
The appearances and nature of mucin complexes have been studied intensively with synovial fluid and similar concentrations of hyaluronic acid, but there is a paucity of information about mucin complexes precipitated from very dilute hyaluronic acid (for example, 2 to 20 Ktg./ml.), which can probably be attributed to the rarity of natural solutions of this order except in bacterial and cellcultu...
