[Analysis of the variations of clinical test data on fasting therapy using fuzzy similarity dendrogram]

The values of assayed various chemical constituents in serum were varied on fasting therapy. The correlationship of the change among such constituents was investigated by drowning the dendrogram using fuzzy similarity relations. Normal and severe obese subjects were respectively selected from the fasting patients at Hyogo prefectural KENKO DOJO, and in contrast non-fasting healthy people were also selected. Fasting was practice under the conditions of 300 Kcal per day for 7 days, and then refeeding was enforced for 7 days after fasting. 21 Items of biochemical tests were used for this analysis, and dendrogram was drown by Otake's method. On the dendrogram of reference, the significant correlations between AST and ALT, Total Protein and Cholinesterase, Sodium and Potassium were found. The dendrogram of fasting period of normal group showed the simple patterns, and unique correlations were drawn on the dendrogram of refeeding period of normal group. The dendrogram of severe obese group of refeeding period showed more simple patterns than fasting period.
