UNLABELLED Although intradermal injection of capsaicin produces acute pain and secondary hyperalgesia, long-term topical application of capsaicin cream has been used as a medication for pain relief in various pain conditions. We previously reported that intrathecal administration of prostaglandin (PG) E(2) and PGF(2alpha) into mice induced touch-evoked pain(More)
Serine proteases are thought to be involved in the initial attack on sheep skin by Dermatophilus congolensis and are obvious antigens for inclusion in a vaccine to prevent lumpy wool disease (dermatophilosis). Degenerate primers were designed after alignment of seven bacterial serine proteases. Inosine was incorporated into the primers at positions of(More)
Data collected monthly over a period of two years were live weight, packed cell volume (PCV), nematode faecal egg counts (FECs) and coccidial oocyst counts from faecal analyses for 100 mixed age (3-7 years) indigenous Tswana does. The aims of this experiment were to determine seasonal FECs and coccidial oocysts in these goats and quantify the relationships(More)
We investigated the effect of intravenous magnesium, a N-methyl-D-asparate (NMDA) receptor antagonist, in 8 patients suffering from neuropathic pain (post herpetic neuralgia or causalgia etc.). After the nerve block, magnesium sulphate (0.5 mol.l-1) 5 ml was administered intravenously by bolus infusion taking 5 min, followed by continuous infusion of the(More)
The paper reports a 5 year old male sheep±goat interspeci®c hybrid born under natural conditions. The hybrid was castrated at 10 months of age. Karyotype analysis con®rmed that the animal was a male and a hybrid with 57 chromosomes, an intermediate number between sheep (2nˆ54) and goat (2nˆ60). Morphological characteristics of the animal were compared with(More)
The presence of gastro-intestinal parasites in Tswana kids (n = 7) aged 1-3 weeks was studied for a period of 6 months at the Botswana College of Agriculture. The aims of this study were to find the time when they first contracted internal parasite infections, as well as to determine the severity of the infections and also its relation to production(More)
