Abnormal flexion of the corono-pedal joint or “contracted tendons” in unweaned foals. A condition frequently misnamed "contracted tendons" is described in unweaned foals. Various theories regarding its aetiology are examined. Overfeeding and lack of exercise are suggested as being the most likely causes, leading to excessive growth of the long bones. An effective method of treatment is described. "Contracted tendons" in yearlings are also discussed.
Osteoporosis in a six year old pony. A case of what can be presumed to be secondary nutritional hyperparathyroidism, due to high phosphorus diet, in a six year old pony is discussed. The findings are compared to those found when the disease occurs in young growing horses.
Enzyme activity in the serum of thoroughbred horses in the United Kingdom. This paper records the concentrations of aspartate amino transferase (A.A.T.), creatine kinase (C.P.K.), sorbitol dehydrogenase (S.D.H.), alpha-hydroxybuturate dehydrogenase (alpha-H.B.D.) and alkaline phosphatase (A.P.) activity observed in the sera of Thoroughbred horses in the United Kingdom, at rest and during training. The methods of analysis have been selected to achieve the optimum precision when used for horse serum. During training A.A.T., C.P.K. and alpha-H.B.D. are related and demonstrate intermittent periods of increasing activity. S.D.H. remains unchanged but demonstrates increase...
The effect of exercise on blood metabolite levels in the horse. The effects of exercise of different intensities on blood concentrations of glucose, lactate, pyruvate, free fatty acids and glycerol were studied in a group of clinically normal horses. Blood lactate, pyruvate and lactate/pyruvate ratio increased during exercise, particularly during galloping. These changes occurred within the first 12-15 seconds of exercise indicating that anaerobic metabolic pathways are brought into use very quickly in the strenuously exercising horse. Since blood glycerol levels were significantly increased during exercise body lipids were also mobilised. At the same time...
The indirect measurement of arterial blood pressure in the horse. An accurate modified auscultatory technique for the indirect measurement of arterial pressure in the horse is described. Limitations of the method were sensitivity to external motion in nervous, conscious horses, and the failure to detect Korotkoff sounds in shocked, anaesthetized surgical cases. The apparatus required for the method is expensive and is probably impractical for routine monitoring during anaesthesia.
Structural and mechanical properties of tendon related to function. Tendon normally fulfills its primary role as a flexible force transmitting element very effectively and yet failure of this passive tissue leads to great disability. As a connective tissue its structure is relatively simple and the peculiar helical arrangement of collagen fibres confers highly non-linear as well as time-dependent mechanical properties. Functional significance cannot be attributed to any facet of mechanical response until the physiological pattern of loading is established. In particular the rate of deformation and the minimum force experienced by tendon in normal locomotion ha...
Ventilation and cardiovascular studies during mechanical control of ventilation in horses. Eleven out of 12 horses were underventilating while breathing spontaneously during halothane anaesthesia with high arterial carbon dioxide tensions. In addition, large alveolar to arterial oxygen tension gradients were found to be present. Mechanically, controlled ventilation with an intermittent positive pressure of 20-30 cm H2O reduced arterial carbon dioxide levels to normal. The alveolar to arterial oxygen gradients did not increase and in some cases decreased. These (A - a) Po2 gradients were due mainly to true shunt of the order of 30 per cent and not to ventilation perfusion inequality....
Cardiac output in the conscious and anaesthetised horse. Cardiac output in the horse was measured before and at predetermined times during 2-hour periods of thiopentone-halothane and thiopentone-diethyl ether anaesthesia. Left ventricular stroke volume was decreased to a similar extent during anaesthesia with each volatile agent, but a greater reduction in cardiac output occurred during halothane anaesthesia. This finding reflected the differing effects of halothane and ether on heart rate, a slight bradycardia occurring with the former agent while ether produced a small degree of tachycardia. The latter effect was attributed to enhanced sympathoadr...
