Jauregui-Adell J.Mare milk and aqueous solution of mare milk lysozyme were incubated for variable times between 30 C and 100 C at pH 3, 6, or 9. Lysozyme activity was stable at acid and neutral pH and labile at alkaline pH. Some of the results show the existence of a reactivation process in mare's milk and in aqueous solution. reaching 30 to 40% after incubation of the aqueous solution at 4 C for 20 days at pH 3 or 6.
ElWishy AB.The morphological changes which take place in the sperm during their passage
through the excurrent ducts have been studied in the bull (BRANTON and SALISBURY
1947; HANCOCK 1955; BAILY and SMITH 1958; AMANN and ALMQUIST 1962; GUSTAFSSON and CRABO 1971 ; RAO 1971) and boar (GUSTAFSSON, CRABO and EINARSSON 1970).
Such knowledge is of major importance in understanding the origin and significance
of the different sperm abnormalties as well as providing the basis for proper appraisal
of semen picture and devising useful spermiograms.
The aim of the present work is to study the morphological ch...
Tobin T, Tai CY, Arnett S.A published method for the recovery of procaine from human plasma using 5M NaOH gave very poor recoveries. Investigation showed that under the recommended extraction conditions procaine was rapidly hydrolysed. Extraction into benzene of samples buffered to pH 9.0 with borate buffer allowed essentially 100% recovery of procaine from equine plasma and urine.
Darbre PD, Romero-Herrera AE, Lehmann H.The tryptic and peptic peptides from the myoglobin of the zebra (Equus burchelli) have been compared with those obtained from the myoglobin of the horse (Equus caballus). No differences in the myoglobin were found between these two species.
Gronwall R, Engelking LR, Anwer MS, Erichsen DF, Klentz RD.Surgically placed bile duct cannulas allowed collection of secreted bile from nonanesthetized ponies. UNINTERRUPTED ENTEROPHEPATIC CIRCULATION WAS PERMITTED BETWEEN COLLECTIONS. Deleterious effects of cannulation were not observed. Average bile flow was 18.6 plus or minus 1.72 (standard error) mul/minute/kg, bile acid excretion was 0.179 plus or minus 0.0212 mumole/minute/kg, and bilirubin excretion averaged 1.22 plus or minus 0.136 mug/minute/kg.
Kamerling JP, Vliegenthart JF.A number of O-acetylated N-acylneuraminic acids, isolated from submandibular glands of cow and horse and from horse erythrocytes, have been characterized by mass spectrometry. On the basis of the typical fragmentation patterns of the pertrimethylsilyl derivatives of the methyl esters of the compounds, they were identified as 4-O-acetyl-, 9-O-acetyl-, 4,9-di-O-acetyl-, and 7,9-di-O-acetyl N-acetylneuraminic acid, and 4-O-acetyl-and 9-O-acetyl-N-glycolylneuraminic acid.
Cabler P, Geddes LA, Rosborough J.Ultrasonic energy, provided by a commercially available water vaporizer, was used to vaporize methoxyflurane, halothane, and chloroform. The vaporizer was placed directly in the respiratory line, and the anaesthetic liquid was vaporized one drop at a time. Anaesthesia was maintained for periods up to 6 hr in horses, ponies, calves, sheep, dogs, and one pig. This method of vaporizing liquids is applicable to a wide variety of anaesthetics. It is easily controlled, and the same vaporizer can be used with a wide range of sizes of subjects. The vaporizer can be placed directly in the respiratory c...
Apukhovska LI, Vendt VP, Ivashkevych SP.Sterols of the whole erythrocytes, hemoglobin, membranes and their protein fractions were studied. Erythrocytes and their components were established to contain, besides cholesterol, other substances of the sterol nature. Cholesterol, 7-dehydrocholesterol and other substances of the cholesterol series are practically completely linked with the lipoproteid fractions of the erythrocyte membrane whereas all sterols found in the native erythrocytes in negligible amounts are bound with hemoglobin.
Ceusters JD, Mouithys-Mickalad AA, Franck TJ, Deby-Dupont GP, Derochette S, Serteyn DA.Horses are outstanding athletes, performing in many different disciplines involving different kinds of efforts and metabolic responses. Depending on exercise intensity, their skeletal muscle oxygenation decreases, and the reperfusion at cessation of the exercise can cause excessive production of free radicals. This study on cultured primary equine myoblasts investigated the effect of different kinds of anoxia/reoxygenation (A/R) on routine respiration, mitochondrial complex I specific activity and free radicals production. Our data revealed that short cycles of A/R caused a decrease of all the...
Morsy AT, Saleh MS, Morsy TA.A zoonosis is an animal disease that is transmissible to humans. Humans are usually an accidental host that acquires disease through close contact with an infected animal, who may or may not be symptomatic. Children are at highest risk for infection because they are more likely to have close contact with pets. Pets are responsible for transmission of an extensive array of bacterial, fungal, and parasitic zoonotic pathogens. The route of transmission can be through the saliva (e.g., bites or contaminated scratches), feces, respiratory secretions, direct contact, or by the animal acting as a veh...

Chanutin S, Bauck AG, Roberts JF, Denagamage TN, Freeman DE.Jejunocaecostomy (JC) is frequently required to bypass diseased ileum as a side-to-side (SS) anastomosis with blind end closure of the small intestine. The effects of the blind end closure method on the performance of the anastomosis have not been studied. Objective: To compare handsewn and stapled blind end closures of the ileum and jejunum. Methods: In vivo experiments. Methods: JC was performed with either Parker-Kerr (PK; 6 horses) or oversewn stapled technique (OS; 6 horses) to close jejunum and ileum for an SS anastomosis. At surgery, peritoneal fluid was analysed and various anastomotic...
In February 2021, a serious EHV-1 outbreak occurred at an international jumping competition in Valencia, with several subsequent outbreaks in various European countries. As a consequence, several equestrian associations introduced compulsory vaccination against EHV-1, and in the immediate aftermath of the outbreak, demand for EHV vaccinations increased sharply. The initial concern has now dissipated. One equestrian association has abolished the compulsory vaccination that had only been introduced a year before, and a general debate began questioning the efficacy and safety of EHV-vaccines. Thi...
Blohina NV, Khrabrova LA.Russia has a significant pedigree diversity of horse breeds with unique gene pools that are well adapted to a wide variety of harsh natural and climatic conditions, are characterized by universal performance and high productive qualities, and are of significant interest to the world horse breeding. Genetic studies of population diversity in horse breeding are very relevant, since many domestic horse breeds are under threat of extinction. Biomaterials (hair, blood, semen) from horses of 15 local breeds bred in the Russian Federation and neighboring countries (CIS) were selected for the research...
Marsella R.Autoimmune dermatopathies are not common in horses. These autoimmune diseases can be idiopathic or triggered by an antigen such as drugs, vaccines, or neoplasia. The most common one is pemphigus foliaceus, which manifests as a pustular, crusting eruption. Other more common pustular diseases should be ruled out before considering pemphigus. Vasculitis is relatively common in horses and can be triggered by a variety of antigenic stimulations. Systemic lupus and true idiopathic autoimmune vasculitis are very rare in horses. Every effort should be made to reach a final diagnosis, as the prognosis ...
Mönki J, Mykkänen A.Mild-moderate and severe equine asthma (MEA and SEA) are prevalent inflammatory airway conditions affecting horses of numerous breeds and disciplines. Despite extensive research, detailed disease pathophysiology and the differences between MEA and SEA are still not completely understood. Bronchoalveolar lavage fluid cytology, broadly used in clinical practice and in equine asthma research, has limited means to represent the inflammatory status in the lower airways. Lipidomics is a field of science that can be utilized in investigating cellular mechanisms and cell-to-cell interactions. Studies ...
