BACKGROUND/AIMS A child presented with hepatic veno-occlusive disease after having been administered a short course of treatment with a traditional herbal remedy. The child subsequently died. Postmortem liver histology confirmed the diagnosis. This study aimed to investigate the hypothesis that the herbal remedy was the cause of veno-occlusive disease. (More)
In a study carried out in two hospitals in South Africa the authors identified 20 children suffering from hepatic veno-occlusive disease thought to be caused by the administration of traditional remedies. The predominant clinical presentation was ascites of various degrees and hepatomegaly. There was a high morbidity and mortality in the young infants, and(More)
A number of traditional remedies used in South Africa contain pyrrolizidine alkaloids, some of which are hepatotoxic. We investigated the effect on human HuH-7 cells of Senecio latifolius DC., a plant that is a component of some traditional remedies and which is known to contain toxic pyrrolizidine alkaloids. Cells were also treated with extracts of a(More)
The fetal and newborn brain is particularly susceptible to hypoxia, which increases the risk for neurodevelopmental deficits, seizures, epilepsy and life-span motor, behavioral and cognitive disabilities. Here, we report that prenatal hypoxia at gestation day 17 in mice caused an immediate decrease in fetal cerebral cortex levels of glutamate decarboxylase,(More)
Poisoning with impila (Callilepis laureola) is a recurring phenomenon in South Africa. Cases of poisoning with other plants which contain atractyloside also occur in Europe and the Americas. Since poisoning leads to rapid death from renal and/or hepatic failure, it is suspected that many cases are undiagnosed; this is especially so in South Africa, where(More)
The traditional Zulu remedy impila (Callilepis laureola) can cause acute fatal hepatocellular necrosis, especially in children. We investigated the mechanism(s) of toxicity using HuH-7 hepatocytes. Impila tubers were extracted with boiling water and the aqueous extract was used at different concentrations to study the effects on the morphology of the cells.(More)
Prenatal hypoxia ischemia is a major cause of neurodevelopmental impairment in the newborn, associated with risk for motor, behavioral and cognitive impaired outcomes. We used an established mouse model of maternal hypoxia to examine the immediate molecular responses of signaling pathways associated with both cell death and neurogenesis. We also(More)
Toxicity related to traditional medicines is becoming more widely recognized as these remedies become popular in developed countries. Accidental herbal toxicity occurs not only as a result of a lack of pharmaceutic quality control in harvesting and preparation but also because herbal remedies are believed to be harmless. Although there is a huge amount of(More)
Preserved human scleral graft and histoacryl-blue tissue adhesive were used in four cases of retinal detachment surgery to obtain scleral buckling effect and to protect staphylomatous or necrotic scleral areas. The use of histoacryl produced a strong and resistant adhesion between the host and the preserved scleral patch. The postoperative inflammatory(More)
