  • Clinical pathological changes in gousiekte, a plant-induced cardiotoxicosis of ruminants 
    Prozesky, Leon; Fourie, Niel; Kellerman, T. Stephanus; Labuschagne, Leonie; Schultz, R.A. (Rowena Anitra); Verwoerd, Daniel Wynand (Published by the Government Printer, Pretoria., 1989)
    Twenty sheep were dosed with either Pachystigma pygmaeum or Fadogia homblei belonging to the Rubiaceae. The experimentally-induced cardiotoxicoses were monitored by various clinical pathological parameters and heart ...
  • Conditioned feed aversion as a means to prevent tulp (Homeria pallida) poisoning in cattle 
    Snyman, Leendert D.; Schultz, R.A. (Rowena Anitra); Joubert, J.P.J.; Basson, Karin M.; Labuschagne, Leonie; Boomker, Jacob Diederik Frederik (Published jointly by the Agricultural Research Council, ARC-Onderstepoort Veterinary Institute and the Faculty of Veterinary Science, University of Pretoria., 2003)
    Conditioned feed aversion was investigated as a means to prevent tulp (Homeria pallida) poisoning in cattle on tulp-infested grazing. Aversion treatment with a combination of epoxyscillirosidin and lithium chloride together ...
  • Continuous exposure to an aversive mixture as a means of maintaining aversion to vermeerbos (Geigeria ornativa O. Hoffm.) in the presence of non-averted sheep 
    Snyman, Leendert D.; Schultz, R.A. (Rowena Anitra); Kellerman, T. Stephanus; Labuschagne, Leonie; Boomker, Jacob Diederik Frederik (Published jointly by the Agricultural Research Council, ARC-Onderstepoort Veterinary Institute and the Faculty of Veterinary Science, University of Pretoria., 2002)
    Continuous exposure to an aversive mixture was investigated as a means of maintaining aversion to vermeerbos in sheep subjected to the social influence of non-averted sheep. The use of an aversive mixture was based on a ...
  • Effect of pavetamine on protein synthesis in rat tissue 
    Prozesky, Leon; Schultz, R.A. (Rowena Anitra); Fourie, Niel; Basson, Karin M.; Labuschagne, Leonie; Boomker, Jacob Diederik Frederik (Published jointly by the Agricultural Research Council, ARC-Onderstepoort Veterinary Institute and the Faculty of Veterinary Science, University of Pretoria., 2001)
    Pavetamine, the active principle of plants causing gousiekte in ruminants, was found in this study to be an inhibitor of protein synthesis in the rat heart. Sprague-Dawley rats were injected intra-peritoneally with 8-10 ...
  • Experimental Albizia versicolor poisoning in sheep and its successful treatment with pyridoxine hydrochloride 
    Gummow, Bruce; Bastianello, Stella S.; Labuschagne, Leonie; Erasmus, G.L.; Verwoerd, Daniel Wynand (Published by the Agricultural Research Council, Onderstepoort Veterinary Institute., 1992)
    Five sheep developed severe nervous signs after being drenched with Albizia versicolor podmaterial. Four of these sheep were treated with pyridoxine hydrochloride (a vitamin B₆) when the symptoms of toxicity became ...
  • Galenia africana L. poisoning in sheep and goats : hepatic and cardiac changes 
    Van der Lugt, Jaco J.; Schultz, R.A. (Rowena Anitra); Fourie, Niel; Hon, L.J.; Jordaan, P.; Labuschagne, Leonie; Verwoerd, Daniel Wynand (Published by the Agricultural Research Council, Onderstepoort Veterinary Institute., 1992)
    Lesions in 4 field cases (3 sheep and 1 goat) of 'waterpens' or water belly, caused by the plant Galenia africana, are described. The clinical pathological and pathological findings in 7 sheep which were drenched with ...
  • Isolation and characterization of and some observations on poisoning by bufadienolides from Cotyledon orbiculata L. var. orbiculata 
    Prozesky, Leon; Anderson, L.A.P.; Schultz, R.A. (Rowena Anitra); Kellerman, T. Stephanus; Kotze, S.M.; Erasmus, G.L.; Labuschagne, Leonie; Bigalke, R.D. (Published by the Government Printer, Pretoria., 1985)
    The approximate LD₅₀ and cumulative effect of 4 bufadienolides, isolated from Cotyledon orbiculata, were determined in guinea-pigs. Two of the bufadienolides proved to be mildly cumulative. One of the mildly cumulative ...
  • Neurotoxicity in calves induced by the plant, Nierembergia hippomanica Miers var. violacea Millan in South Africa 
    Botha, C.J. (Christoffel Jacobus); Schultz, R.A. (Rowena Anitra); Van der Lugt, Jaco J.; Retief, E.; Labuschagne, Leonie; Verwoerd, Daniel Wynand (Published by the Agricultural Research Council, Onderstepoort Veterinary Institute, 1999)
    The plant Nierembergia hippomanica var. violacea has been incriminated in field outbreaks of neurotoxicity in calves in the Free State Province. Hepatotoxicity and electrocardiogram (ECG) deviations were induced in a ...
