Help, mijn paard heeft regenschurft

Hypoglycin A in maple trees in the Netherlands and the risk of equine atypical myopathy
No full textThe Acer (maple) genus of trees comprises over 120 species worldwide. Some of these contain the plant-toxin hypoglycin-A which has been proven to be a cause of the highly fatal condition called atypical myopathy (AM) in horses and ponies. In an earlier study of maple-tree samples (leaves and seeds) collected by owners of healthy and AM-affected horses it was shown that the seeds contain significantly more toxin than the leaves. There is a concern as to whether maple trees can be safely retained or planted around paddocks or pastures, and whether there is a difference in toxicity between different species. The aim of the present study was to investigate the amount of toxin in different maple-tree species present in The Netherlands. The seeds of 20 different tree-species of the ‘Acer’ genus, present in the arboretum in Wageningen, The Netherlands, were analysed for hypoglycin-A; 8 species belonged to the ‘Platanoidea’ subgenus (section), 7 to the ‘Acer’, 3 to the ‘Palmata’ and 2 to the ‘Negundo’ subgenera. Assay was carried out using a newly validated method based on liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). Seeds of the maple trees belonging to the ‘Platanoidea’ contained no hypoglycin-A. The seeds of species belonging to the ‘Acer’, ‘Palmata’ and ‘Negundo’ subgenera however contained 96– 1744 mg/kg, 4–32 mg/kg and 3–444 mg/kg of the toxin respectively. These results indicate that the precise tree species is an important aspect when giving advice regarding the toxicity of maple trees and the consequent risk for horses

A placebo controlled clinical trial on cetirizine in seasonal headshakers
No full textTrigeminal mediated headshaking is a syndrome that may have several causes and is a potential threat to the wellbeing of the horse. Because one of the possible etiologies is an allergic rhinitis, a randomized double-blinded placebo controlled clinical trial on the effectiveness of cetirizine, an antihistamine, in 30 seasonal headshakers was performed. A lunge protocol of 9 min, consisting of rest, walk and trot, was recorded at the start, after a week of treatment with cetirizine and after a week of placebo. Weather conditions were also recorded and owners kept a diary.The videos were scored for the amount of shakes. The overall amount of shakes was 67 ± 94 at the start and 47 ± 72 on cetirizine. This difference was significant (P = 0.01). Placebo compared to start was not significantly different (P = 0.18) as was cetirizine vs placebo (P = 0.74). Evaluating results of individual horses 10 horses showed >50% improvement on cetirizine and 11 horses showed a >50% improvement on placebo (compared to t = 0). Factors like weather circumstances will be taken into account.This study shows the difficulty of using a clinical trial for a syndrome influenced by weather and many other factors. It does suggest however that even if cetirizine will not be beneficial in all (seasonal) headshaking horses, it may be in some, both diagnostic for proving an allergic etiology, as well as therapeutic which is also suggested by follow-up of these horses and other clinical cases
Colonial Office Correspondence Relating To Brunei 'destroyed Under Statute' 1906–1934
No full textIn this paper the author scans the registers of correspondence relating to
Brunei (1906–34) held in the National Archives at Kew. An annotated
checklist of documents is provided. It is concluded that useful data can be
yielded; and that, in a case such as Brunei, where documentation is in short
supply, no potential source of information should be neglected. The exercise
raises issues about the preservation of historical records. Suggestions for
further research are provided
