After preliminary toxicity and efficacy models on experimentally infected dogs, in addition, to the reference posology (2.5 mg of melarsomine (RM 340)/kg twice, 24 h apart by deep IM injection) a more practical program for vet practitioners was suggested (2.2 mg/kg twice, 3 h apart) using modelization of the pharmacokinetic data. The two treatments were equivalent as shown on models with experimental infection of dogs, critical tests on naturally infected dogs and clinical trials in veterinary practice. We advise using specific and well adapted therapeutic programs for each of the clinical classes (class 1: subclinical, class 2: moderate, class 3: severe). The safety margin is respectively x 3 or x 2.5 in contrast with thiacetarsamide which, being hepatotoxic, has no safety margin, and sometimes is nephrotoxic at the recommended dose. RM 340 is fully effective on D immitis adults (even on young ones of 7 months old) and L5 immatures (4 months old) when thiacetarsamide is poorly effective on 7 months or ineffective on 4-month-old parasites. Clinical trials in veterinary practice showed that the programs are well adapted to many clinical situations. The product is effective, relatively safe and easy to handle by IM injection. Preliminary results show its possible use as tactical treatment (2.2 mg/kg twice, 3 h apart) twice a year in mid August and December-January to prevent heartworm disease.</p>","PeriodicalId":7914,"journal":{"name":"Annales de recherches veterinaires.

A silver impregnation technique allowed a precise visualization of thyroid follicles on histological sections. The histomorphometric values (cell height, follicular diameter, percentage of epithelial cells) were obtained using a semi-automatic image analyser. The statistical tests used were analysis of variance (Fisher's test) and the Newman-Keuls tests. The results obtained showed that thyroxin treatment did not lead to any modification in histomorphometric values. Propylthiouracil, on the contrary, caused profound alterations in the morphology of thyroid follicles and in particular an increase in the height of the follicular epithelium. These changes were induced by a deficiency in thyroid hormones leading to an increase in thyroid-stimulating hormone (TSH) release. This study shows that with rigorous methodology, histomorphometry is adaptable to the requirements of a simple and reproducible evaluation of substances capable of causing functional perturbations and their effects on the thyroid gland.</p>","PeriodicalId":7914,"journal":{"name":"Annales de recherches veterinaires.
