Topic:Clinical Study
Clinical studies in equine research involve the systematic investigation of health and disease in horses through structured scientific methods. These studies aim to evaluate the safety and efficacy of treatments, understand disease mechanisms, and improve veterinary care practices. Clinical studies can include randomized controlled trials, observational studies, and case-control studies. They may focus on various aspects such as pharmacokinetics, therapeutic interventions, and diagnostic techniques. This page compiles peer-reviewed research studies and scholarly articles that explore the design, implementation, and findings of clinical studies in equine medicine, providing insights into their impact on horse health and veterinary practices.
Cytology of diffuse mesothelioma in the thorax of a horse. Examination of effusions from body cavities must include a search for neoplastic as well as inflammatory cells. Neoplastic cells found in the thorax are generally derived from adenocarcinomas or mesotheliomas. Mesotheliomas are relatively uncommon and the neoplastic cells found in effusions are difficult to differentiate from activated cells in inflammatory effusions. An ante-mortem diagnosis of mesothelioma was made in a mare on the basis of the large volume of fluid produced, the pleomorphic mesothelial cells, the polyp formation and the absence of PAS staining material after digestion of th...
The therapeutic activity, post-treatment fertility and safety of prostaglandin F2alpha-Tham salt in clinically anoestrous mares: a review. Of 275 mares receiving prostaglandin F2alpha-Tham salt for its luteolytic effect upon the corpus luteum, 231 (84 per cent) exhibited signs of oestrus (range 73-95 per cent). Some mares not exhibiting overt oestrus may, nevertheless, ovulate and post-treatment rectal palpation of mares apparently failing to respond is suggested in these cases. Of 210 mares for which subsequent history was available. 104 (49.5 per cent) became pregnant from breeding at the post-treatment oestrus that immediately followed the induced regression of the corpus luteum (range 42.2-55.5 per cent). Fertility is compara...
Preliminary studies of pharmacological antigonism of anaphylaxis in the horse. Systemic anaphylaxis was induced in seven groups of ponies. Systemic hypotension, pulmonary hypotension, and apnea were observed in the control group. Suppression of anaphylaxis was achieved most efficiently with sodium meclofenamate followed by acetylsalicylic acid and diethylcarboamazine. Tripelennamine and methysergide reduced anaphylaxis minimally and burimamide not at all. The findings suggest that histamine and serotonin are of relatively low significance in equine anaphylaxis whereas kinins, prostaglandins and slow reacting substance may be more important.
A preliminary study of the measurement of plasma osmotic pressure in equine medicine. The normal plasma osmotic pressure was established in 205 Thoroughbred horses. Samples taken from horses suffering from a variety of diseases showed that measurement of this parameter might prove a valuable non specific test for assessing the severity of some diseases in which there are alterations in metabolism.
A case of peritoneal mesothelioma in a thoroughbred mare. The report describes a case of abdominal neoplasia in a mare diagnosed ante-mortem by the technique of paracentesis abdominis. Histopathological findings suggest that the lesion was a mesothelioma, primarily involving the greater omentum.
Mefanamic acid blood and urine levels in the horse determined by derivative gas-liquid chromatography-electron capture. Mefenamic acid is extracted from biological fluids and is acylated with pentafluoropropionic anhydride to form a derivative possessing high electron affinity. The derivative is analyzed by gas-liquid chromatography with an electron capture detector. The method is particularly valuable for determining drug levels in blood where small sample and/or drug concentrations are available.
Salmonellosis in Equidae: a study of 23 cases. Salmonellosis in Equidae is a serious global problem. The prevalence may range from 0.36% to 27%. Probably 5% to 10% of the equine population in the U.S. is or has been infected. Over 40 serotypes of Salmonella have been cultured from Equidae. S. typhimurium (66.31%), S. enteritidis (9.6%), S. newport (5.16%) and S. heidelberg (4.89%) have been the most common equine isolates. The clinical and bacteriological studies of 23 naturally occurring infections in a large veterinary hospital were studied. Nine patients were infected with S. typhimurium, 8 with S. anatum, 1 with S. newport, 4 with dual...
Therapy of a horse with diarrhoea of unknown aetiology. A 5 year old Thoroughbred stallion with diarrhoea of unknown aetiology was referred to Davis. Treatment was aimed at terminating diarrhoea and restoring normal fluid status. Laboratory aids were utilised to establish where inbalance and deficits were present. Antibiotics and corticosteroids were used as an adjunct to fluid therapy. The case history and rationale of treatment of fluid disorders resulting from diarrhoea are discussed.
Proceedings: Influence of etorphine, acepromazine and diprenorphine on cardiovascular function in ponies. The neuroleptanalgesic drug combination of
etorphine and acepromazine (Large Animal
Immobilon; Reckitt & Colman Ltd.) was
administered i.v. at the recommended dose rate
(24 ,ug/kg etorphine and 100 pg/kg acepromazine)
to twelve Welsh Mountain ponies of 185 to 336 kg
bodyweight. Cardiovascular measurements were
made before and at pre-determined times up to
30 min after the injection. The etorphine
antagonist, diprenorphine (Revivon; Reckitt &
Colman Ltd.), was then injected i.v. (30,ug/kg)
and further measurements were obtained.
Pronounced increases in heart rate, moderate
increase...
Evaluation of adenosine deaminase and other purine salvage pathway enzymes in horses with combined immunodeficiency. Foals with combined immunodeficiency had normal levels of purine salvage pathway enzymes, including adenosine deaminase, nucleoside phosphorylase, and xanthine oxidase.
A clinincal evaluation of abdominal paracentesis in the horse. This paper evaluates the usefulness of abdominal paracentesis as a diagnostic aid in abdominal disease in the horse and in particular considers whether or not it can be effectively utilised as an indication for surgical intervention in cases of colic. The results are based upon peritoneal fluid samples collected from 20 normal horses and from 20 cases of colic and peritonitis. Peritoneal fluid was collected from standing horses by inserting a bovine teat cannula into the horses abdomen through the linea alba after desensitisation of the skin on the ventral midline with local anaesthetic. Usual...
