RESUMO
The three-dimensional optoelectronic locomotion analysis system SELSPOT II was used for kinematic studies of hind limb locomotion patterns. Two groups, 11 sound horses and 15 horses suffering from hind limb lameness, were examined at the trot. Both graphical and quantitative analyses were compared in sound and lame horses. The parameter hip acceleration quotient (HAQ), using the different peaks of vertical acceleration of one hip during one stride, proved to be a suitable value for quantitative analysis of hind limb lameness. In sound horses the HAQ ranged from 1.03 to 1.54, lame horses showed values between 1.32 and 2.96. Checking and documentation of diagnostic anesthesias or therapies are possible applications.

In seven sound horses histamine plasma levels were evaluated by means of a radioenzymatic method using the enzyme histamine-N-methyltransferase (mean = 4.46 nmol/l, SD = 1.55 nmol/l). Histamine levels of laminitic horses were significantly higher (n = 11; mean = 12.46 nmol/l, SD = 3.24 nmol/l). In three sound horses plasma histamine levels were determined over a two week period following a double administration of 10 mg dexamethasone-21-isonicotinate/100 kg body weight. Histamine levels remained within the range of sound control horses.

Thrombosis of the aorta as the cause of intermittent claudication in the horse appears to be rare. Two cases out of about 10 000 horses 1973-1984 are discussed. There are various views on its aetiology, whereby haemodynamic factors and disturbances of coagulation have been mentioned as well as parasites. For treatment surgical methods should be explored in addition to medical procedures. History, diagnosis and the attempt of an aortic thrombectomy in a 12 year old thoroughbred mare are described in this paper. A standardbred stallion was left untreated on owners wish.
