Most of the African traditional medicines (ATM) are formulated as energy tonics to boost and maintain immune defences. In this study, we aimed to evaluate the immune effects of a traditional energy tonic using peripheral blood mononuclear cells (PBMCs), THP-1 monocytes, and bacteria infected rats.
A 1-yr-old intact male African lion (Panthera leo) fed only beef muscle meat was evaluated for episodes of hypermetric ataxia, generalized weakness and tonic-clonic front limb movements. A hemogram, biochemical profile, blood lead, electrocardiogram, survey radiographs, and brain computed tomography
ABSTRACT This study determines soman toxicity in African green monkeys (Chlorocebus aethiops) and is the first step in exploring the suitability of this species as a model for nerve agent studies. Male African green monkeys were surgically implanted with telemetry devices to monitor

The recent listeriosis outbreak in South Africa (SA) received widespread attention in the media. More than 1 000 laboratory-confirmed cases of listeriosis occurred during an 18-month period, with a case fatality rate of 28%. Acute bacterial meningitis due to listeriosis was extremely We measured gastric juice fluid output, acidity, tonic strength (osmolality), and pepsin concentrations basally and after the injection of pentagastrin in 120 healthy African Americans and 60 Caucasian Americans of similar age and gender. Sera for basal gastrin concentration and IgG for antibody to
Charcot-Marie-Tooth disease 1A (CMT1A) is the most common autosomal dominant demyelinating sensorimotor polyneuropathy. A few patients with Charcot-Marie-Tooth disease were reported in the literature to have epilepsy. We report on an African-American boy with CMT1A, with duplication of peripheral
METHODS
A 14-year-old Congo African grey parrot (Psittacus erithacus erithacus) was evaluated for an acute onset of falling off of its perch and tonic-clonic movements.
RESULTS
Clinical signs were consistent with partial seizures. Findings on whole-body radiography, CBC, and plasma biochemical
BACKGROUND
Commercial herbal medicines (CHMs) being marketed as immune boosters or tonics, have gained widespread popularity. The many herbal mixtures sold have not been tested for efficacy and safety, despite their modern packaging and presentations. It is imperative that these herbal mixtures be
Commercial herbal medicines (CHMs) marketed as immune boosters are gaining wide popularity in South Africa, in the absence of control and regulatory guidelines. These commercially packaged and labelled herbal preparations, acquired in various retail outlets, are used without consulting African Americans have a greater prevalence of hypertension and diabetes compared with white Americans, and both autonomic dysregulation and inflammation have been implicated in the etiology of these disease states. The purpose of this study was to examine the cardiac autonomic and systemic
Scadoxus puniceus (Amaryllidaceae), a medicinal plant of high value in South Africa, is used as a component of a traditional herbal tonic prescribed to treat several ailments. Ultra-high performance liquid chromatography-tandem mass spectrometry quantified the phenolic compounds in different organs
The vasorelaxing effect of isolates (compounds 1, 2, 3, and 4 (homoisoflavanones), compound 5 (sesquiterpenoid), compounds 6 and 7 (bufadienolides)) from the South African Hyacinthaceae has been assessed using rat aortic ring preparations. Compounds 2, 3, and 4 inhibited the tonic contraction
