Tracheotomy means the incision of the trachea with the aim to bypass the nasal area, larynx and cranial trachea. Tracheotomy is often performed as an emergency procedure under difficult conditions. This article firstly describes the anatomy, histology and clinical examination of the trachea in horses. Secondly, it gives the indications for temporary tracheotomy, surgical technique as well as associated risks. [less ▲]

OBJECTIVE: To evaluate a human assay for quantification of carboxy-terminal cross-linking telopeptide of type I collagen (CTX-I), assess the influence of age on plasma CTX-I concentration, investigate the relationship between plasma CTX-I and serum osteocalcin concentrations, and determine whether concentrations of plasma CTX-I or serum osteocalcin fluctuate in circadian manner in horses. HORSES: 75 clinically normal horses. PROCEDURE: Cross-reactivity between equine serum CTX-I and CTX-I antibodies in an automated electrochemiluminescent sandwich antibody assay (ECLIA) was evaluated via a specificity test (ie, dilution test) and recovery calculation. Serum osteocalcin concentration was measured with an equine-specific osteocalcin radioimmunoassay. To analyze diurnal variations in plasma CTX-I and serum osteocalcin concentrations, blood samples were obtained hourly during a 24-hour period. RESULTS: Results of the dilution test indicated good correlation (r > 0.99) between expected serum CTX-I concentrations and measured serum CTX-I concentrations. The calculated CTX-I recovery was 97.6% to 109.9%. Plasma CTX-I and serum osteocalcin concentrations were correlated. Plasma CTX-I concentration was inversely correlated with age of the horse. No significant circadian variations in plasma CTX-I and serum osteocalcin concentrations were detected. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that the fully automated CTX-I ECLIA can be used for evaluation of plasma and serum samples from horses and may be a useful tool to monitor bone metabolism changes. Horses in this study did not have notable diurnal fluctuations in serum osteocalcin and plasma CTX-I concentrations. [less ▲]

This study describes for the first time the development and validation of a sensitive and specific radioimmunoassay (RIA) for equine osteocalcin (OC) quantification using purified equine OC as standard, tracer, and immunogen for antibody formation in rabbits. The assay allowed to measure equine serum OC levels with a sensitivity of 0.2 ng/mL. Immunoreactive serum OC values of clinically normal, different-aged horses ranged from 3.68 to 127.31 ng/mL. Intra- and inter-assay coefficients of variation (CV) were 6.2 and 8.2%, respectively. Serial equine scrum sample dilutions were linear. The recovery of equine OC from equine serum samples ranged from 93.88 to 107.9%. There was a tight correlation between OC values measured with the equine- specific OC RIA and two commercially available bovine-specific OC RIA kits. However, highest serum OC values were obtained with the equine-specific OC RIA. In conclusion, our equine-specific OC RIA is sensitive, linear, accurate, precise, and reproducible. The assay allowed to quantify OC in equine serum samples and might, therefore, be used to monitor equine osteoblast activity associated with bone diseases, exercise, therapy forms or diet. [less ▲]

Equine bone gamma-carboxyglutamic acid containing protein - also called osteocalcin - has been isolated for the first time till homogeneity. After acid demineralisation and acid extraction, the purification procedure was based on reverse phase chromatography, gel filtration and ion exchange chromatography. The amino acid sequence of the primary structure has been determined to be YLDHWLGA(HYP) APYPDPL(GLA)PRR(GLA)VC (GLA)LNPDCDELADHIGF-AYRRFYGPV. The protein has a calculated molecular weight of 5,732 kDa and a calculated isoelectric point of 4,45. It contains 49 amino acids, from which 3 are gamma-carboxyglutamic acid residues at position 17, 21 and 24 and has a fully hydroxylated proline in position nine and cysteine in position 23 and 29. Equine osteocalcin shows a strong homology with bovine (98%), ovine (96%) and human (94%) osteocalcin [less ▲]
