    In the normal parturition of cows, the serum cortisol (FK) level was 13.2±6.4 ng/ml (unit omitted hereafter) in the opening (1) stage, 22.9±8.1 in the delivery (2) stage, and 23.2±5.7 in the postpartum (3) stage (especially within 3 hours after delivery). It was significantly higher in stages 2 and 3 than in stage 1 (p<0.05). There was no significant difference in it between stages 2 and 3.
    In the abnormal parturition of cows, the serum FK level was 48.2±24.2, 50.2±11.5, and 56.8±14.4 in stages 1, 2, and 3, respectively. There was no significant difference in it between any two stages. These cows showed a significantly higher serum FK level in every stage than those normal in parturition.
    The serum FK level of calves immediately after birth was significantly higher than that of the cows normal in parturition in every stage (p<0.01), and than that of those abnormal in parturition in stages 2 and 3 (p<0.05). There was no significant difference in serum FK level between calves normally born and those abnormally born from dairy cows.

    Twenty-four pigs experimentally infected with swine epizootic pneumonia (SEP) were divided equally into four groups. Three groups, 1 to 3, were treated with 25, 50, and 100 ppm tyamulin, an antibiotic of the diterpene group, respectively. The other group served as control.
    As a result, coughing was inhibited more effectively in groups 2 and 3 than in any other group. Feed demand was lower in rate in groups 2 and 3 than in any other group. Autopsy revealed much severer pneumonic changes in the control group and group 1 than in the other groups.
    It was assumed that 50 ppm or more of tyamulin might be effective for the spontaneous case of infection in the field.

    Five species of amphibians, Rana nigromaculata, R.catesbeiana, R.rugosa, Hyla arborea japonica, and Triturus pyrrhogaster pyrrhogaster, and reptilian species, Rhabdophis tigrinus tigrinus, were collected from Toyohashi, Aichi Prefecture, from June to September, 1979, and examined for parasites.Metacercariae were found in the mesentery and intramuscular connective tissue, and identified as Pharyngostomum cordatum by morphological examination of adult flukes obtained from cats experimentally infected with those metacercariae.In these cats, the epithelium was lost from the sites of the intestine harboring the flukes.
