Efficacy of a Single Oral Dose of Oxfendazole against Fasciola hepatica in Naturally Infected Sheep

AbstractA new fasciolicide, triclabendazole, tested at single oral dose rates of 5 and lOmg/kg body-weight, proved to be highly effective (>99%) against chronic field infections of Fasciola hepatica and F. gigantica in sheep. The Performance of the new drug compared favourably with niclofolan at the recommended dose. Neither product was effective against Dicrocoelium dendriticum and Paramphistomum spp.

Highly Effective

Paramphistomosis is considered an emergent disease of ruminants in Europe. Some drugs have been found effective for treating paramphistomid infections in cattle, but data in sheep are currently limited. Thus, faecal samples from 25 adult sheep naturally infected with paramphistomids were collected weekly to test the efficacy of oxyclozanide and closantel. Three groups were performed: nine animals orally treated with a single dose of oxyclozanide (15 mg/kg bodyweight (BW) integrated the G-OXI group, whereas eight sheep orally treated with a single dose of closantel (10 mg/kg BW) were placed in a group called G-CLS. Eight untreated controls constituted the group G-CON. Oxyclozanide showed efficacies up to 90% until week 11 post-treatment, with a maximum efficacy of 98.3%, and significant differences were found between G-OXI and G-CON until the 26th week post-treatment. Closantel was insufficiently active (0–81%) throughout the study and differences compared to G-CON were never found. The present study reveals that oxyclozanide given at a single oral dose of 15 mg/kg BW is highly effective against adult rumen flukes in sheep. In addition, the use of a single oral dose of closantel at 10 mg/kg BW is not recommended for treating paramphistomid infections in sheep.

Suppression Test

Des mesurages répétés de la fixation thyroïdienne de 10 minutes du 132I injecté intraveineusement on été effectués sur 55 malades euthyroïdiens sans et avec goitre et sur 16 malades hyperthyreoïdiens par 4 jours consécutifs. Immédiatement après le premier mesurage tous les malades recevaient une dose unique oral de 100 μg de Triiodothyronine (T3). Les valeurs de fixation 24, 48 et 72 heures après le T3 (moyen ± déviation standard) étaient de 75 ± 1,7, 64 ± 1,8, et 67 ± 1,9 dans le groupe euthyroïdien et le 106 ± 2,6, 104 ± 2,2 et 108 ± 4,0 dans le groupe hyperthyroïdien, exprimés en pourcentage du groupe controle. 48 heures après T3 tous les personnes euthyroïdiens, sauf une, avaient des valeurs en dessous de 88% tandis que la valeur la plus basse des personnes hyperthyroïdiens ce jour était de 93%. La séparation des valeurs 48 heures des deux groupes était complète après avoir respecté l’influence de la première fixation sur la valeur 48 heures. On peut donc supposer q’un test thyroïdien de suppression utilisable en clinique peut-être effectué en 48 heures après une administration oral de 100 μg de T3 et mesurage de la fixation 10 minutes après l’injection du radioisotope.

Platelet Release

SummaryThrombelastograms of both native blood and re-calcified platelet-rich plasma samples taken from subjects given a single oral dose of aspirin (1 gram) were not significantly different from the pretreatment recordings. Aspirin also did not modify the thrombelastogram when preincubated in vitro with platelet-rich plasma at concentrations inhibiting the platelet “release reaction” by collagen. Thrombelastography therefore cannot evaluate the effect of aspirin on platelet function.

Abstract. The effects of a single oral dose of phenobarbital (PB) on the 24 h secretion of prolactin, growth hormone and luteinizing hormone have been evaluated in normal women. An EEG record was taken and barbiturate levels assayed in serum. A statistically significant decrease of growth hormone 24 h mean levels was observed and growth hormone and prolactin values during sleep were diminished. No changes in luteinizing hormone concentrations were observed. After PB the EEG showed no important alterations in sleep pattern, but on the power analysis an increase above 16 Hz absolute power was detected during the waking period.
