Ramadan, A., A. Afifi, and M. Issa, "Comparative studies on the effect of continuous intravenous infusion of some sulphonamides on blood and urine glucose levels in buffaloes.", DTW. Deutsche tierarztliche Wochenschrift, vol. 96, issue 7, pp. 376-7, 1989 Jul-Aug. Abstract

Three groups of five clinically healthy buffaloes each were injected intravenously with sulphadiazine, sulphadimidine and sulphamerazine in a dose of 100 mg/kg b. wt. (as a singly initial dose of 40 mg/kg b. wt. an subsequently the plasma level kept constant by a continuous intravenous infusion of a maintenance dose of 20 mg/kg per hour over a period of 3 hours). It was found that, 1) sulphadiazine, sulphadimidine and sulphamerazine increase the plasma glucose levels at 1, 2, 2.5 and 3.5 hours from the start of i.v. infusion. 2) The glucose concentration in urine increased in the buffaloes infused i.v. with sulphadiazine. 3) The glucose level in urine of buffaloes infused i.v. with sulphadimidine and sulphamerazine was slightly increased. 4) The concentrations of sulphadiazine, sulphadimidine and sulphamerazine in plasma reached its highest level, 2.5, 2 and 2.5 hours during the i.v. infusion, respectively, then declined rapidly. 5) The concentrations of sulphadiazine, sulphadimidine and sulphamerazine in urine reached their highest concentrations 3.5 hours after i.v. infusion.

Atef, M., S. A. Youssef, A. Ramadan, and M. Issa, "Kinetic disposition, systemic bioavailability, tissue levels and acetylation of some sulphonamides in goats.", Archives internationales de pharmacodynamie et de therapie, vol. 302, pp. 27-39, 1989 Nov-Dec. Abstract

Sulphamethoxazole, sulphadimethyloxazole and sulphadimethoxine were once administered in goats via oral and i.v. route (100 mg/kg b.wt.) for determination of plasma and urine concentrations of the unchanged sulphonamides and their acetylated derivatives, kinetic behavior, systemic bioavailability, tissue levels and acetylation. The highest plasma concentrations of sulphamethoxazole, sulphadimethyloxazole and sulphadimethoxine were reached after 0.64, 1.31 and 0.46 hr following oral administration, with an absorption half-life of 0.84, 1.31 and 0.38 hr and an elimination half-life of 3.51, 5.01 and 5.55 hr, respectively. Following a single i.v. injection, the kinetic disposition of sulphamethoxazole and sulphadimethoxine followed a one-compartmental model with an elimination half-life of 1.48 and 1.76 hr and a total body clearance-time curve of sulphadimethyloxazole, after a single i.v. injection, could be described by a two-compartmental open model with an elimination half-life of 3.27 hr, a volume of distribution of 248.07 ml/kg and a total body clearance of 0.82 ml/kg/min. The systemic bioavailability was 19.95, 11.37 and 23.27% after oral administration of sulphamethoxazole, sulphadimethyloxazole and sulphadimethoxine, respectively. The percentages of serum protein binding of sulphamethoxazole, sulphadimethyloxazole and sulphadimethoxine were determined in most of the body tissues, collected 4 hr after i.v. injection. The highest concentration was found in kidney and liver. On the other hand, sulphamethoxazole, sulphadimethyloxazole and sulphadimethoxine were N4-acetylated in the body tissues to a higher extent than that in plasma. Acetylation was highest in rumen and skeletal muscle.

Ohtsuka, N., M. E. Shabshiry, M. Ismail, A. Faessler, and J. Aichelin, "Does photon production in heavy-ion collisions depend on the equation of state?", Journal of Physics G: Nuclear and Particle Physics, vol. 16, no. 8, pp. L155-L161, 1990. AbstractWebsite

Photon production cross sections in 12C-12C and 40Ca-40Ca collisions at Elab=84 and 200 MeV/A are calculated in the framework of the quantum molecular dynamics approach using the medium-dependent NN cross section obtained from the G matrix. Photons are assumed to be produced by incoherent pn bremsstrahlung and a simple classical expression for the production cross section is used. The effects of the equation of state for nuclear matter on the photon production cross section are studied in detail. In the 12C-12C collision, the authors found little difference in the photon cross section due to differences in the equation of state both at 84 and 200 MeV/A. In the 40Ca-40Ca collision, slightly more high-energy photons are produced in the case of the soft equation of state and the difference is slightly larger at higher incident energies.
