Plasma samples were taken at regular intervals after dosing and assayed for radioactivity and D-alpha-tocopherol. Plasma profiles were modelized using a compartmental approach and the input entry rate (for radioactivity) was identified using a numerical deconvolution method. Based on plasma specific activity (dose 1 and dose 4) and D-alpha-tocopherol plasma concentration (unlabelled alpha-tocopherol acetate), half-lives were not significantly different (99.6 +/- 28.3 h, 121.3 +/- 38.5 h and 75.0 +/- 49.75 h after dose 1, dose 4 and unlabelled alpha-tocopherol respectively). The times to reach maximal plasma concentrations were similar for the 3 test articles (mean values ranging from 21.5 to 26.7 h). The only significant difference was observed for the apparent volume of distribution (with respect to bioavailability) which was much larger for the unlabelled test article. Deconvolution study of plasma specific activity showed: i), that the maximal input rate was reached only after a short delay (3 to 12 h); ii), that half of the activity was absorbed after a delay of 38.13 +/- 16.76 h (dose 1) and 44.3 +/- 6.50 h (dose 4); and iii), that 90% of the activity was absorbed after 151.2 +/- 27.3 h (dose 1) and 162.3 +/- 11.2 (dose 4). It is concluded that the intraperitoneal route is of interest for alpha-tocopherol administration, but that more information is required to determine the exact process of absorption.</p>","PeriodicalId":7914,"journal":{"name":"Annales de recherches veterinaires.

The degree of cellular immunity was followed by examining delayed hypersensitivity using 3 allergens (bovine tuberculin PPD, avian tuberculin PPD and johnine PPD) and that of humoral immunity using complement fixation test, agar gel immunodiffusion test and ELISA. The elimination of bacilli in the faeces was examined simultaneously. After 2 years no macroscopic or microscopic lesion was observed in intravenously inoculated lambs and in those exposed orally to M paratuberculosis; cultures were negative. It appears that domestic sheep were able to control the infection. Nevertheless, most of them developed cellular and humoral immunity against paratuberculosis antigen.

Sixteen of the 17 pigs showed symptoms of hog cholera. The virus was detected in the blood of the 16 pigs during all phases of hyperthermia which persisted up to death or the terminal phase, ie between 16 and 29 days post-infection. One animal recovered after presenting a mild form of the disease. This pig was the only one which raised antibodies to the virus.
