Seasonal changes in blood serum protein fractions and in activity of AspAT and AlAT in Arabian brood mares and their foals. In 34 pure breed Arabian horses divided into four groups (Gr. I--10 pregnant mares, Gr. II--7 barren mares, Gr. III--10 foals born in 1981, Gr. IV--7 foals born in 1982) seasonal changes in total blood serum protein, its electrophoretic fractions and the activity of AspAT and AlAT were studied. Seasonal cyclicity was found in all groups in the amount of total serum proteins, and alpha 2- and beta 1-globulin fractions. Cyclicity was found in the level of albumin and activity of AspAT in three groups, not Gr. II, and in gamma-globulin, not Gr. IV. beta 2-globulin and AlAT cyclicity was found in ...
Characteristics of Mycoplasma strains isolated from stallion semen. Eleven mycoplasma strains were isolated from the semen of 24 stallions. Eight of these strains were identified as Mycoplasma equigenitalium. Three strains which hydrolized arginine could not be identified. The growth inhibition test with immune sera against M. arginini and M. equirhinis was negative. Antibiotic sensitivity test showed that all strains were sensitive to four antibiotic of tetracycline group (oxytetracyclin, minocycline, transcycline and vibramycin). Lincomycin and gentamycin appeared to be the most active against all the strains. Comparative analysis of routine semen examinatio...
[Postoperative wound infection in the horse]. A systemic investigation of wound infection in the horse after operative treatment of large wounds reveals that the age of the wound is of critical importance. The limit for an uncomplicated healing process lies around four hours. The duration of the operation itself is of little significance, the location of the lesion on the body of the horse, however, plays a major role. The pattern of isolated bacterial organisms is discussed in relation to the duration of hospital treatment. It is concluded that a systemic antibiotic therapy is of no value and that a local antibiotic therapy is only indic...
Clinical anaesthesia in the horse: comparison of enflurane and halothane. Anaesthesia was induced in 24 horses with xylazine and ketamine and maintained with halothane (12 cases) or enflurane (12 cases) in oxygen. Pulse rate, arterial blood pressure, arterial blood gas values, respiratory rate and tidal volume were measured at regular intervals during anaesthesia. Serial venous blood samples were taken for assay of glucose, urea, haemoglobin, packed cell volume, gamma glutamyl transpeptidase, aspartate aminotransferase, alanine aminotransferase and creatine kinase. Operating conditions and the horses' behaviour in the recovery period were also recorded. In the case ...
Investigating the CO2 laser for plantar digital neurectomy in horses. A histological study of plantar digital nerve sections cut with a carbon dioxide laser in horses was conducted. A series of nerve cuts were made with variable power densities to determine the appropriate theoretical level which would yield the most desired tissue effects. Power densities in the lower ranges used appeared to provide tissue effects judged most likely to prevent neuroma formation through increased thermal sealing of the proximal stump at the axon level. Clinical observation and follow-up of horses subjected to laser neurectomy tend to support the reported concept that the laser i...
Sensory nerve endings in the peroneus tertius muscle of the ass and horse: a functional hypothesis. The various types of sensory nerve endings found in the peroneus tertius muscle in the ass and in the horse have been studied with Ruffini's gold chloride method. Free nerve endings have been described as well as encapsulated receptors. These corpuscles are classified as Pacini-like, Ruffini's terminations and also Golgi's tendon-organs. The authors have pointed out the morphology, topography and structural characteristics of the above named nervous terminations and have hypothesized that a probable functional relation existed between these nervous corpuscles and the considered tendinous struc...
Three-year study on trace mineral concentration in the blood plasma of Shetland pony mares. Changes in some trace minerals concentrations (calcium, inorganic phosphorus, magnesium, zinc, iron, copper, sodium and potassium) in blood plasma were investigated during a three-year period in Shetland pony mares. Blood plasma mineral concentrations were determined by the atomic absorption method and colorimetric method. The three-year averages were in micrograms/ml; Na 4630 +/- 168; K 277 +/- 3.8; Ca 171 +/- 3.8; P 31.5 +/- 0.74; Fe 1.92 +/- 0.14; Zn 1.07 +/- 0.04 and Cu 1.06 +/- 0.02. Two trace minerals (magnesium in inorganic phosphorus) showed only long-term tendency changes--upward or d...
Electroencephalographic patterns of clinically normal, sedated, and tranquilized newborn foals and adult horses. To establish a clinically practical procedure for recording the equine EEG, 25 healthy adult horses and 6 newborn foals were used. Recordings were taken with the animals alert and tranquilized, confined in metal stocks, or physically restrained. The dominant alert waveforms of adult horses were fast activity (25 to 40 Hz) with medium-to-low voltages (5 to 40 microV-dominant 10 to 15 microV). Underlying this fast activity was slower (0.5 to 4.0 Hz) activity with medium-to-low voltages (10 to 40 microV). Twelve of the 25 adult horses had EEG frequencies in the alpha frequency range (10 to 15 Hz,...
Cardiopulmonary effects of dopamine hydrochloride in anaesthetised horses. Dopamine hydrochloride was infused intravenously into six horses anaesthetised with halothane. Three dose rates; 0.5, 2.5 and 5.0 micrograms/kg/min, were evaluated in each horse. The cardiac output was significantly increased at 15 and 30 mins following administration of dopamine at 2.5 and 5.0 micrograms/kg/min. The heart rate, facial artery pressure and pulmonary artery pressure remained unchanged. Total peripheral resistance was significantly decreased at 30 mins with 2.5 micrograms/kg/min and at 15 and 30 mins with 5.0 micrograms/kg/min. No significant change was produced in packed cell vo...
Equine tracheobronchial lavage: comparison of lavage cytologic and pulmonary histopathologic findings. Differential cell counts were done on bronchial lavage specimens from 166 horses. Postmortem gross and histologic examinations were done to determine the pathologic diagnosis of the lungs from these horses. Ninety-two (55%) were normal, 18 (11%) had interstitial pneumonia, 13 (8%) had bronchopneumonia, 13 (8%) had focal eosinophilia, 11 (7%) had diffuse eosinophilia, 11 (7%) had chronic bronchitis, and 8 (5%) had suppurative bronchitis. Little relationship was found between cellular features of the lavage specimens and the pathologic status of the lungs of individual horses.
[Functional anatomy of the visceral arteries in the abdominal cavity of the horse. Considerations with reference to intestinal colic]. The microscopic structure of the arteries was investigated in the gastro-intestinal tract of the horse. The median artery was also studied for comparative purposes. The adventitia is responsible for the holding and suspension of the visceral arteries. Disturbances in this system are considered to be a prime factor leading to chronically deficient blood flow. This is associated with pain which is generally classified as colics.
Effects of dietary energy supply on serum thyroxine, tri-iodothyronine and insulin concentrations in young horses. The effects of meal ingestion on the circulating concentrations of the growth-regulating hormones thyroxine (T4), tri-iodothyronine (T3) and insulin were examined in weanling Thoroughbreds fed 70% (diet A), 100% (diet B) or 130% (diet C) of their energy and protein requirements. Peak insulin concentrations occurred 1, 2 and 3 h after the ingestion of diets C, B and A respectively. Increases in plasma glucose concentrations preceded the increases in serum insulin concentrations. Serum T4 concentrations increased after the ingestion of diets A and B and decreased after diet C. In contrast, serum...
Tendon injuries in horses treated with carbon fibre implants. Implants of carbon fibre, made by plaiting a tow of 10,000 filaments of Grafil type HT-S, were used to treat strains and ruptures of digital flexor tendons in 46 horses. The relevant clinical data, the techniques employed and an analysis of the results are described. Apart from two horses in which the implant was extruded and had to be removed, there were minimal untoward consequences of the surgery. Of the 34 horses with acute or chronic tendinitis, 14 returned to racing, seven were used as hunters and seven as hacks. Among the former group, seven suffered a further strain while racing but th...
[Results of the surgical treatment of colic, represented by case material of 1983 from the Munich-Riem horse hospital]. The results of the ileus surgery in horses by a consistent performing of a known and standardised clinical and operative procedure are very good, provided that there are surgeons who have experience in abdominal surgery and that there is a co-operating team for the pre- and post-operative care.
Influence of several perturbants on the rate of autoxidation of horse heart ferrocytochrome c. The effect of several different types of perturbants and pH on the rate of autoxidation of horse heart ferrocytochrome c was investigated. The kinetic behavior is unique to each perturbant used. Rates of autoxidation followed first-order kinetics over the time span (0-180 min) studied. The Cl- and Br- anions exhibit an initial increase in the rate of autoxidation up to 100 mM, followed by a decrease in kinetics at 500 mM anion concentration. The ClO4- anion exhibits only an increase in the rate of autoxidation with increasing ionic strength, where as, propylurea, a hydrophobic perturbant, is n...
Detection of Corynebacterium equi-specific antibody in horses by enzyme-linked immunosorbent assay. An enzyme-linked immunosorbant assay was developed to measure naturally occurring Corynebacterium equi specific antibody in horse serum. Antibody against C equi was demonstrated in normal adults and was passively transferred to foals. Adult levels of specific antibody were reached by 5 to 6 months of age in healthy foals. Decreased early antibody levels were demonstrated in a limited number of foals with confirmed C equi infection.
