Protein profiles of whole homogenates of anconeus (slow twitch) and biceps femoris (fast twitch) muscles of clinically normal dogs and of Labrador Retrievers with hereditary myopathy (HM) were resolved on flat bed polyacrylamide isoelectric-focusing gels. Three methods of sample solubilization were performed. The solubilization buffer, with high concentrations of urea, precipitated the zwitterionic detergent, but use of the buffer containing 3% NP-40, 9.2M urea, and 0.1M arginine resulted in better resolution and stability of pH gradient. Gels of anconeus muscle from clinically normal dogs contained 2 protein bands specific to anconeus muscle, whereas gels of biceps femoris muscle from clinically normal dogs contained 3 protein bands amplified in biceps femoris muscle that were barely detectable in anconeus muscle. The staining intensity of protein bands in biceps femoris muscles from Labrador Retrievers with HM was decreased, relative to controls. The quantitative analysis of peak height ratios of biceps femoris muscle revealed significant (P less than 0.05) differences between profiles of clinically normal dogs and Labrador Retrievers with HM.

A study was undertaken to determine the pressor and toxic effects of etoposide, an antineoplastic agent, when administered IV in 0.9% sodium chloride solution (0.4 mg of etoposide/ml) over a 30-minute period to dogs at a dosage of 40 mg/m2 of body surface. On day 1, 6 adult German Shorthaired Pointers were anesthetized with halothane, and blood pressures were measured via a femoral artery catheter before, during, and after the etoposide was administered. Systolic, diastolic, and mean blood pressures of each dog increased significantly (P less than 0.01) within 30 minutes after initiation of etoposide infusion. On day 3, when the dogs were not anesthetized, etoposide was again administered to each dog, using the same dosage. Each dog developed a moderate to severe cutaneous reaction characterized by moderate to severe pruritus, urticaria, and swelling of the head and extremities that began during the second infusion of etoposide. These same cutaneous reactions were seen on day 30, when etoposide was administered to 3 of the previously treated dogs and 2 previously untreated Beagles. We concluded that the administration of the commercial preparation of etoposide is likely to cause a significant reduction in blood pressure of anesthetized dogs, and that the drug is likely to induce a moderate to severe cutaneous reaction when administered to unanesthetized dogs.

Animal bones excavated with earthenware from the shell mound at the Jeju Jongdali 1819 archeological site, where three consecutive chronological layers covering the Neolithic (B.C. 15C-B.C. 10C), early Tamra, and late Tamra periods have been identified, were morphologically classified. The majority of the bones from all three periods were broken or split. The major fauna of the mammalian bones in all periods were Cervus spp., Sus scrofa, and Bos taurus. In the early and late Tamra periods, bones of small animals including Mustela sibirica coreana, Meles meles, Rodentia, and Aves were also found in small number. The excavated bones were from all parts of the animal bodies, including head, trunk, forelimb, and hindlimb. Collectively, these findings suggest that the major fauna from the Neolithic to late Tamra periods consisted of Cervus spp., Sus scrofa, and Bos taurus and that the fauna was dissected and carried to the shell mound site after hunting. Information from the bone remains in the shell mound are useful data for study of the wildlife and domestic animals living during the prehistoric period of Jeju Island.

Analysis of data on distribution of clinicopathologic symptoms of rhinotracheitis, parainfluenza-3, bovine viral diarrhoea, clamidiosis, rhinosyncytial virus, adenovirus diseases, rotaviral diseases, coronavirus infections of cattle, viral transmissible gastroenteritis, and respiratory reproductive syndrome of swine, rinderpest, rabies and Aujesky disease of agricultural animals in the conditions of the Republic of Belarus was realized. There were given descriptions of diagnostic tests and vaccines for disease prevention used in Belarus and other countries. Treatment regimen and methods and other elements of prophylaxis were presented. There was given an analysis of prophylactic efficiency of produced medicine drugs

An interpretation of concepts 'norm' and 'pathology' in the veterinary medicine and medicine from the point of dialectic and materialistic theory was analyzed. There was given an interpretation of 'norm' as a complex of average indexes of state of vital function of body; interpretation of pathological process, pathological conditions and diseases. There was analyzed the philosophical concept of reasons and consequences in etiology and pathophysiologic mechanisms of diseases, as well as criticism of terms causalism and conditionalism
