The study evaluates effects of varied doses of ascorbic acid and piroxicam on behavioural signs of pain in orchidectomised Savannah Brown goats during their postsurgical pain management. The goats were divided into 6 groups of 3 goats each. Orchidectomy was performed on all animals under sedation with xylazine and linear infiltration with lignocaine. After surgery, varied doses of piroxicam (IM) and ascorbic acid (IV) were administered to the goats: Group A = piroxicam, 5 mg/kg + ascorbic acid, 100 mg/kg; Group B = piroxicam, 5 mg/kg + ascorbic acid, 200 mg/kg; Group C = piroxicam, 10 mg/kg + ascorbic acid, 100 mg/kg; Group D = piroxicam, 5 mg/kg; Group E: ascorbic acid, 100 mg/kg together with antibiotics, procaine penicillin, 20,000 IU/kg + streptomycin, 10 mg/kg (IM); and Group F (control) received only the antibiotics. After surgery, pain intensity was determined in each goat by numerical rating scale. Vocalisation, teeth grinding, rapid and shallow breathing, tail wagging, occasionally bleating, neck extension, and dorsal lip curling were recorded at varying degrees across the experimental groups. The goats in the control group showed the highest degree of behavioural signs of pain. It is concluded that treatment with a combination of piroxicam and ascorbic acid ameliorated pain more than either of the agents in orchidectomised Savannah Brown goats.
Evaluation of the effect of piroxicam and ascorbic acid combination on live weight and rectal temperature of savannah brown goats during post-operative pain management,
Due to the increased use of ultrasound in the diagnosis of cyesis, it is necessary to study the possible adverse effect of insonation on thyroid hormone in fetuses. Sixteen (16) adult rabbit does that had kindled at least once were used for the study and were scanned using a Medison S600V ® Ultrasound machine with a 6.5MHz transcutaneous curve-linear probe. All does were mated naturally by the introduction of a doe to a buck and then divided randomly into two groups. The does that were scanned (insonated)-, were properly restrained on dorsal recumbency, liberally shaved; aquasonic gel applied and scanned using a transcutaneous curve-linear probe for 5 minutes on the 5 th day post coitus and thereafter on days 7, 12, 15, 20, 25, 27 and 29. The restrain and scanning procedures were mimicked on the group of does that were not scanned (non-insonated). Upon parturition, blood was collected from kits and serum was extracted and used to assay for total thyroxine (tT4) and triiodothyronine (tT3). Fetal thyroid glands were also harvested for histologic study. Mean tT3 concentration was 1.60 ± 0.90 µg/dl and 1.58 ± 0.03 µg/dl while mean tT4 was 1.46 ± 0.10 µg/dl and 1.39 ± 0.07 µg/dl for the non-insonated and insonated groups, respectively. P values of 0.610 and 0.132 for tT3 and tT4 concentration respectively showed that there is no statistically significant difference in the values even though there was a numerical difference between the groups. No histopathologic change on fetal thyroid gland from both groups was observed. In conclusion, although the values were not significantly different, the numerical decrease of both tT3 and tT4 in the insonated rabbits suggest the possibility that insonation could alter their values in fetuses when the threshold of ultrasound waves are increased and insonation prolonged.
