Disturbances of calciumhomeostasishave beenassociatedwithavarietyofdisease conditions inanimals.Knowledge of serumtotal calciumvalues is essential for understanding disease states that cause calciumalterations outside the reference range. Variations in albumin values can affect the proportion of protein-bound calciumin the total calcium concentration.Adjustment formulas ofmeasured calciumbased onmeasuredalbumin or total protein concentrations were proposed byMeuten et al (MeutenDJ, ChewDJ, CapenCCandKocibaGJ. 1982. Am. Vet.Med. Assoc. 180, 63- 67): adjustedcalcium=calcium albumin+3.5 or adjustedcalcium=calcium 0.4 xprotein+3.3. This studywas aimed todevelop relationships between serumtotal calciumandalbumin andbetween serumtotal calciumandtotal protein atdifferent clinical settings, andtocompare these relationshipswithMeuten's. Eachequationvarieddependingonthe laboratories, andtherewas aignificant difference in regression slopes between laboratories. The prevalence of calcium disturbance based on the albumin and total protein equation ranging 0.7-12.1%and 4.6 -19.3%, respectively. These findings suggest that adjustingcalciumformulasmust bedevelopedseparatelyat different clinical settings. Bytheuse of their own formulas, it becomes possible to interpret abnormal calcium values correctly in patients with various clinical conditions.

Effect of perilla oil on the fatty acid composition, ACAT and HMG-CoA reductase in the liver microsomes, or cholesterol and protein in serum of rabbit were examined. 1. The content of total protein in serum was almost same amount of both groups, but α1-globulin and r-globuline were incresed or β-globulin was decresed compared with control. 2. The content of high density lipoprotein incresed, and the content of low density lipoprotein decresed in lipoprotein. 3. Total cholesterol and triglyceride were decresed, and the content of phospholipid was incresed. 4. Perilla oil did not effect for changing blood glucose and Na+, K+ electrolytes. 5. Perilla oil did not effect for changing serum GOT and GPT in rabbit. 6. The activity of ACAT decresed and the activity of HMG-CoA reductase incresed. The activity of ACAT and HMG-CoA reductase in liver microsomes were reciprocal. 7. There were arachidonic acid 20:4, eicosapentaenoic acid 20:5, and docosahexaenoic acid 22:6 in the liver microsomes of rabbits. These highly polyunsaturated fatty acids were convented from linolenic acid 18:3 n-3.

Several authors reported that vegetable proteins cause to decrease serum cholesterol and reported the effect of limiting amino acid balance in dietary protein on the blood component. This study was designed to observe growth rate and blood component in 1% cholesterol-fed male rats intake pure isolated soy proteins and methionine for 4 weeks. The diets were supplemented with either 20% casein or isolated soy protein as dietary protein sources and methionine as limiting amino acid of isolated soy protein and casein protein. The results were as follows; 1) The body weight gain was the greatest in casein groups. 2) Serum total cholesterol concentration was significantly increased by casein groups and slightly decreased by isolated soy protein groups. 3) Serum HDL-cholesterol concentration was significantly increased by isolated soy protein groups than control group. 4) Serum total lipid and triglyceride concentrations were significantly decreased by isolated soy protein groups than control group. 5) Serum glucose concentration was significantly increased by isolated soy protein plus 0.8% methionine than control group. 6) Serum total protein and albumin concentrations were significantly increased by all experimental diets groups than control group. Especially, casein groups were the most increased in all experimental diets groups.
