Lysozyme activity of high-leucocyte-count milk and the effect of heat and potassium dichromate on lysozyme activity.
No support could be found for the hypothesis that mastitis, as evidenced by increased leucocyte counts in milk, is accompanied by an increase in lysozyme activity. The presence of potassium dichromate in the preserved milk samples did not seem to affect lysozyme activity. The sensitivity of lysozyme to heat was demonstrated. All lysozyme isolates and purifications were made with deaminated chitin affinity chromatography.
Protein, casein, and noncasein protein percentages in milk with high somatic cell counts.
More than 1000 milk samples of individual cows with somatic cell counts ranging from 20,000 to 20,000,000 per ml were analyzed by amido black dye binding for total protein, whey protein, and casein. Ten classes of varying somatic cell counts were established. The mean total protein percentage for normal samples (counts less than 500,000/ml) was 3.2% and different from all the other protein class means, ranging from 3.4 to 3.9%. Total protein content increased with somatic cell count. There was no significant difference among any of the ten classes for casein values. Whey protein percentages for normal samples were different from the rest. Whey protein content increased with somatic cell count.
Amido black dye binding of alfalfa and forage legume protein.
Although dye binding has been suggested for the determination of alfalfa protein content, a standard method has not been advanced. More data are necessary on the conditions required for the dye-protein reaction. Reaction times of 8, 12 and 24 hours and reaction temperatures of 50, 55, 60 and 65 degrees C were selected to obtain dye binding values (DBV) with the Foss Pro-Milk apparatus. A correlation of 0.88 with macro-Kjeldahl values was obtained. 60 degrees C and 24 hours reaction time can be considered conditions yielding maximum DBV. It is suggested to develop a standard method for the routine measurement of forage legume content.

Sedation for pediatric patients undergoing CT and MRI.
Adequate sedation remains one of the most important parts of performing high quality cross-sectional imaging in children. This is a noncomparative retrospective analysis of existing sedation protocols used in 1,158 children between the ages of 1 day and 18 years, checking for safety and efficacy. The most commonly used drugs were chloral hydrate (60-120 mg/kg) by mouth for infants less than 18 months and intravenous Nembutal (2-6 mg/kg) for older children. Sedation was successful in 97% of patients.
