Topic:Respiratory Health
Respiratory health in horses encompasses the study of the equine respiratory system, its function, and the various conditions that can affect it. The respiratory system in horses includes the upper airways, lungs, and associated structures, which facilitate gas exchange and are vital for maintaining physiological homeostasis during rest and exercise. Common respiratory conditions in horses include equine asthma, infectious diseases like strangles, and exercise-induced pulmonary hemorrhage (EIPH). These conditions can impact a horse's performance and overall health. This page compiles peer-reviewed research studies and scholarly articles that explore the anatomy, physiology, pathophysiology, and management of respiratory health in horses.
Acute rhabdomyolysis (“tying-up”) in standardbred horses. A morphological and biochemical study. LINDHOLM, A., H.-E. JOHANSSON & P. KJÆRSGAARD: Acute rhabdomyolysis (“tying-up”) in standardbred horses. A morphological and biochemical study. Acta vet. scand. 1974, 15, 325–339. — Morphological, biochemical and histochemical changes were studied in muscle needle biopsy specimens (gluteus medius) from 59 standardbred trotters with acute clinical symptoms of the “tying-up” disease. All horses had increased levels of serum enzymes SGOT and SCPK. The biopsy specimens were taken at various intervals after onset of clinical symptoms (1–4 hrs., 18–24 hrs. and 2–20 days). Ry l...
A kininogen-kinin like reaction revealed by the marginal distance of the equine lung.
Summary
Wetting an area 40 × 40 cm. with water at around 16 °C produces a marked increase in the marginal distance of the horse lung (distance between limits of pulmonary sound and sound of thoracic wall) which persists for an average of 4 1/2 hours. The treated area, but no other area, of skin remains totally refractory for more than 7 hours and partially refractory for more than 28 but less than 46 hours. Phenylbutazone (7 mg./kg. i. v.) prevents the effect. A kininogen-kinin effect is considered the likely explanation. Camphor produced similar changes to those caused by cold water.

Acute systemic anaphylaxis in the horse. 1. Histamine in small doses caused systemic depressor responses in horses, whereas greater doses caused biphasic effects. All doses of 5-hydroxytrypt-amine (5-HT) were pressor and all doses of bradykinin depressor. All three active substances raised pulmonary artery pressure and lowered central venous pressure. 5-HT reduced ventilation volume. Histamine caused brief apnoea followed by hyperpnoea only.2. Acute anaphylaxis in the horse was accompanied by a severe systemic arterial depressor response, a pressor response in the pulmonary artery and vena cava, and alternating phases of apnoea and d...
Chronic pulmonary disease in the horse. Several forms of chronic pulmonary disease in the horse can be differentiated, to some extent, by simple means within the scope of every clinician. The proposed diagnostic system permits more precise diagnoses, which are supported by histopathological evidence. Such diagnoses justify a reasonably accurate prognosis of a horse's chance of recovery. They also have been used as a basis for constructing a pathogenetic model.
Among the factors involved in the pathogenesis of chronic pulmonary disease, ageing has probably been overrated.
Climatic changes influence the symptomatology and the co...
Drugs, performance and responses to exercise in the racehorse. 1. Physiological observations on the cardiac and respiratory responses. The research focuses on understanding the physiological responses, mainly cardiovascular and respiratory, of racehorses during exercise and how drugs can impact these responses. The study aims to set up a [...]
