title: [Canonical discriminant analysis for pregnancy-related changes in hematological and serum biochemical values in tamarins (Saguinus spp].
abstract: Hematological and biochemical values obtained from 9 monkeys (Saguinus labiatus and S. mistax) during pre- and postpartum periods were analyzed by canonical discriminant analysis (discriminant analysis with reduction of dimensionality). All animals used were of wild origin and had been maintained under uniform environmental conditions at N. I. H., Japan. The items examined were as follows: white blood cell count (WBC), red blood cell count (RBC), hematocrit value (Ht), hemoglobin concentration (Hb), total protein concentration (TP), blood urea nitrogen (BUN), albumin concentration (ALB), albumin-globulin ratio (A/G), glutamic oxaloacetic transaminase activity (GGT), glutamic pyruvic transaminase activity (GPT), alkaline phosphatase activity (ALP) and total cholesterol concentration (CHO). The data obtained in the pre- and postpartum periods were divided into six chronological groups. The prepartum period was divided into Group I: weeks 15-10; Group II: weeks 9-7; Group III: weeks 6-4; and Group IV: weeks 3-0. The postpartum period was divided into Group V: weeks 0-4 and Group VI: weeks 5-7). In the later pregnancy period (Groups III and IV), significant decreases in RBC, Ht, Hb, TP and ALB, and a significant increase in CHO were observed. These values in the blood and serum continued after delivery (Groups V and VI). Results of canonical discriminant analysis showed that the value of the first canonical variate decreased according to the progress of pregnancy. The postpartum groups showed negative values. Although groups in the early
