1. The effects of streptozotocin-diabetes on the local and general responses to a 4 h period of bilateral hind-limb ischaemia in the rat have been investigated. The rats were injured 48 h after the intravenous injection of the streptozotocin. 2. Less fluid was lost from the circulation into the injured limbs after injury in the diabetic rats and this was directly related to the severity of the ...

BACKGROUND Local circulatory disturbances have been implicated in the development of foot disorders in cattle. The goals of this study were to evaluate the suitability of the interdigital artery in the pastern region in both hind limbs using pulsed-wave (PW) Doppler ultrasonography and to investigate quantitative arterial blood flow variables at that site in dairy cows. An Esaote MyLabOne ultra...

At first glance, the strategy for generating propulsive impulses for both jumping and swimming in frogs is quite similar. Both modes rely on powerful extension of the hind limbs. However, in Rana esculenta (the semi-aquatic green frog), propulsive impulses for jumping were found to be much larger than those generated during swimming [Nauwelaerts and Aerts, 2003. Propulsive impulses as a covaryi...

The first case of post anaesthetic myelopathy in a horse is described. A two year old 530 kg Shire stallion underwent surgical removal of a granuloma in the ventral sternal region under general inhalation anaesthesia in dorsal recumbency. Total duration of the operation was 85 min. The anaesthesia was uneventful except for profuse sweating and arterial hypertension observed during the whole per...

Ammonia production by hind limbs of rat was studied in perfused preparations during rest, exercise, and hypoxia, and while the perfusate contained epinephrine or cyanide. Ammonia production by hind limbs was also studied in situ during rest and exercise. Strong correlations were observed between ammonia, IMP, and lactate formation. Adenylosuccinate was not present in detectable amounts in resti...

The dorsal-side-up body posture in standing quadrupeds is maintained by the postural system, which includes spinal and supraspinal mechanisms driven by somatosensory inputs from the limbs. A number of descending tracts can transmit supraspinal commands for postural corrections. The first aim of this study was to understand whether the rubrospinal tract participates in their transmission. We rec...

The aim of this report is to describe a presumptive diagnosis spina bifida in mixed breed dog, due previous diagnostic inconsistencies. Spina an uncommon congenital anomaly characterized by poor bone formation incomplete closure or the absence dorsal arch vertebral structure during process embryogenesis. Animals with condition may have difficulties locomotion process, which constantly threatens...

Stride duration, stance duration and protraction duration are key variables when describing the gaits of terrestrial animals. Together, they determine the duty factor (the fraction of the stride for which the limb maintains contact with the ground surface), from which the peak vertical force can be estimated. When an animal changes speed, these variables change at different proportions. Limited...
