To examine the nephrotoxicity of prolonged gentamicin administration compared to the effect obtained when a less toxic aminoglycoside is substituted during the course of treatment, we gave gentamicin (67.5 mg/kg per day) to rats for 21 days, gentamicin for 14 days followed by either netilmicin or tobramycin for 7 days, or gentamicin for 14 days followed by saline diluent. After initial tubular,...

Air-segmentation is applied to amplitude-modulated multiplexed flow analysis, which we proposed recently. Sample solutions, the flow rates of which are varied periodically, are merged with reagent and/or diluent solution. The merged stream is segmented by air-bubbles and, downstream, its absorbance is measured after deaeration. The analytes in the samples are quantified from the amplitudes of t...

After kaolin treatment of fetal rabbit serum, 7S antibody titers were reduced more than 19S titers. This reduction was less when the kaolin treatment was performed at pH 9.0 than when it was performed at pH 7.3. A modification of the kaolin treatment of sera for use in the hemagglutination-inhibiting antibody titration, in which the hemagglutination reaction is performed at a neutral pH, is rec...

Premix feed is a mixture containing one or more additives and diluent carrier after mixed evenly, which plays an important role in cattle feeding. In this paper, the characteristics functions of premix feeds were analyzed, effects adding fat, vitamins, microelements other mixtures daily on reproductive performance different postpartum diseases expounded.

The biodegradability of leachate from the land treatment of hydrocarboncontaminated soil was investigated in the laboratory using respirometry and toxicity test­ ing in combination with total petroleum hydrocarbon (TPH) measurements. Soil in land treatment units (LTU) had been contaminated with a diesellike hydrocarbon mixture formerly used as a diluent for crude oil at an oil field in Californ...

The term “immediate release” pharmaceutical formulation includes any in which the rate of release drug from or absorption drug, is neither appreciably, nor intentionally, retarded by galenic manipulations. These tablets disintegrate rapidly and get dissolved to medicaments. It may be provided for way an appropriate pharmaceutically acceptable diluent carrier, carrier does not prolong, appreciab...

During the past four years numerous articles have been published in which eosinophil counts have been used in the control of therapy by A.C.T.H. In most of these the counts have been performed by using four Fuchs-Rosenthal counting chambers for each count. The author also used these counting chambers for the experimental work on a new diluent for eosinophil counts (Manners, 1951), but found the...
