Turnover and urinary excretion of free and acetylated MS-222 rainbow trout, Salmo gairdneri Turnover and urinary excretion of free and acetylated MS-222 rainbow trout, Salmo gairdneri
Rainbow trout (Salmo gairdneri) anesthetized in 100 mg/liter of M.S. 222 at 12 C excreted the drug in free and acetylated forms via the urine during a 24-hr recovery period in freshwater. Of the M.S. 222 excreted, 77-96% was acetylated. Blood levels of free drug in anesthetized trout approximated 75% of the anesthetic concentration, but the amount of acetylated M.S. 222 was relatively

Water resources of Wisconsin, Fox-Wolf River basin Water resources of Wisconsin, Fox-Wolf River basin
PURPOSE AND SCOPE The purposes of this report are to (1) describe the geohydrology of the basin, (2) describe and relate the surface- and ground-water systems, (3) discuss existing and possible future water problems in the basin, and (4) to suggest means of possible solutions. The scope of the study was to interpret and relate streamflow, climatic, geologic, and ground-water information...

Water resources of the Lac Qui Parle River Watershed, Southwestern Minnesota Water resources of the Lac Qui Parle River Watershed, Southwestern Minnesota
The Lac qui Parle River watershed is underlain by thick water-bearing sections of glacial drift and Cretaceous rocks. Drainage is from the Coteau des Praries, a plateau in the southwest, to the Lac qui Parle reservoir, about 800 feet lower than the plateau. The term "watershed" as used in this report refers to that part of the drainage basin (767 square miles) within Minnesota. The total...

Water resources of the Mississippi Headwaters Watershed, North-central Minnesota Water resources of the Mississippi Headwaters Watershed, North-central Minnesota
The Mississippi Headwaters watershed is a 7,608 square mile area in north-central Minnesota which includes all land drained by the Mississippi River above the Crow Wing River. From its source in Lake Itasca, 1,460 feet above mean sea level, the Mississippi River follows a semicircular 376 mile course to where it leaves the watershed at an altitude of 1,150 feet. The origin of the river...

Gas chromatographic separation and quantitative estimation of barbiturate mixtures in solid dosage forms Gas chromatographic separation and quantitative estimation of barbiturate mixtures in solid dosage forms
A gas chromatographic method has been described for the analysis of mixed barbiturates in solid dosage forms. Analysis on a 10% SE-30 column gave good separations for butabarbital, amobarbital, secobarbital, pentobarbital, and/or phenobarbital; amobarbital is not separated adequately from pentobarbital. An internal standard, mephobarbital, is used to minimize injection errors. The method...

Water resources of the Mustinka and Bois de Sioux Rivers watershed, west-central Minnesota Water resources of the Mustinka and Bois de Sioux Rivers watershed, west-central Minnesota
The Mustinka and Bois de Sioux Rivers watershed is mantled by till deposits with scattered sand deposits. The west-central and northwestern part of the watershed was covered by Glacial Lake Agassiz and the resulting land surface is a flat, lake-washed till plain. Patches and ridges of sand scattered throughout the lake plain were formed as beach ridges and offshore bars. Small, isolated...
