The influence of feedstuffs treated with ionizing radiation on the nutrition of dogs was tested in four groups of animals. Two groups were administered for 90 days a ration, the main part of which (VETACAN meat feed mixture and VETAVIT loose feed mixture) was irradiated with radioisotope Co 60 of the intensity of 25 kGy/kg, in other two groups of dogs the nonirradiated ration was used for the same time period. The control groups of dogs were put together for these two diets. The laboratory examination of irradiated feedstuffs confirmed their complete microbiological and mycological intactness. However, the irradiation brought about a significant 35% degradation of essential amino acids with an increase of ammonia nitrogen, destructive changes in the lipid component of feedstuffs and a partial decomposition of the saccharide part of the VETAVIT feed mixture, expressed by the acidity of water extract. The sensory evaluation of irradiated feedstuffs did not show any perceptible alterations. The haematological examination of the blood of animals, which had been administered irradiated feed rations, demonstrated a significant negative influence on the blood picture. The biochemical examination of the blood serum and plasma revealed that total proteins of experimental dogs dropped and the creatinine level was also significantly decreased. Neither was the level of carbohydrate nutrition nor the energy saturation affected by irradiation. The glucose levels in the blood serum of dogs fluctuated within the range of physiological reference values. The growth of free ammoniacal bases of feedstuffs, evoked by ionizing radiation, conditioned obviously the level of actual pH of blood in dogs as determined in this study. The destruction of lipoid fraction in the feedstuffs induced a decrease in the activity of lipophile retinol and thus the biological value of feeds was impaired. The biochemical examination of ALT, AST and ALP enzyme activity did not show any increased activity of parenchyma, in particular of liver cell. A decisive role of the biological quality of feed ration for utilization of some minerals was demonstrated by a significant decrease of the magnesium level in animals administered irradiated feed rations without any biological supplementation. On the contrary, the potassium, calcium and phosphorus levels did not reflect this dietary difference between the groups.

After surgical placement of end-to-side portacaval shunts (PCS), 4 adult mongrel dogs (11.8 to 18.2 kg) were fed purified diets and monitored for approximately 50 weeks for changes in body weight, neurologic status, and an array of clinically important biochemical variables. Two healthy dogs, fed the same diets and maintained in the same environment, were also observed (controls). Body weights were relatively stable over the period of observation. The branched-chain ratio ([valine] + [leucine] + [isoleucine]/[phenylalanine] + [tyrosine]), an index of the degree of change in plasma amino acid concentrations, was significantly lower in dogs with PCS than in controls. Despite this depression in branched-chain ratio, the principals (dogs with PCS) were essentially free of neurologic symptoms. Statistically significant decreases due to portacaval shunting were seen in the serum concentrations of glucose, calcium, urea nitrogen, creatinine, cholesterol, and albumin. Total protein, globulin, and triglyceride concentrations tended to be lower in the serum of principals than in serum of controls, but the differences were not statistically significant. Statistically significant increases due to portacaval shunting were seen in plasma concentrations of total conjugated bile acids and sulfobromophthalein retention. Concentrations of the following compounds tended to be higher in serum of principals than in serum of controls: phosphorus, chloride, uric acid, total bilirubin, lactate dehydrogenase, aspartate transaminase, alanine transaminase, and alkaline phosphatase. Liver biopsy at 7 months after operation showed mild-to-extensive atrophy of hepatocytes, mild-to-extensive fibrosis, and collapsed portal veins in all principals examined.

The changes in the metabolic status of both testis and ovary of Chrysocoris stolli following the treatment with juvenile hormone analogue (JHa) and ecdysterone were studied. After the exogenous application of JHa in selective dose, total carbohydrate, glycogen, trehalose, cholesterol, ascorbic acid and inorganic phosphorus increased significantly whereas free fatty acid (FFA), phospholipid, total protein, RNA and DNA decreased significantly in comparison to control of both testis and ovary. Total lipid significantly decreased in testis and significantly increased in ovary after JHa injection. The activities of cellular enzymes like alkaline phosphatase, 5' nucleotidase, catalase and peroxidase significantly decreased while acid phosphatase and GPT significantly increased after the JHa application in comparison to control both in testis and ovary. Activities of GOT and general esterase significantly decreased in testis and increased in ovary after JHa application. The exogenous application of ecdysterone also brought about the similar kind of responses as was noticed in case of JHa treatment but these two treatments differed in some cases such as ecdysteroid that produced some results which were just the reverse of what was produced by JHa treatment. The results obtained here were explained in terms of mode of action of these two hormones.

The pathophysiologic responses of 13 sheep inoculated orally with 100 metacercariae of Fascioloides magna were monitored for 4 months after inoculation. There were no differences in weight gains between these and a number of noninoculated control sheep throughout the experiment. Complete blood cell counts showed an increase only in the absolute number of eosinophils. Serum preparations (2 times a week) from 7 inoculated and 7 noninoculated sheep did not identify any significant changes in alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, and gamma-glutamyl transferase activities. There were no changes in total bilirubin, BUN, creatinine, inorganic phosphorus, calcium, albumin, chloride, potassium, and sodium values. Four months after they were inoculated, all sheep were necropsied, and flukes were recovered. Gross lesions attributed to fluke migration were found in the liver and portal lymph nodes, diaphragm, lungs, kidneys, and spleen. Microscopically, liver lesions in inoculated sheep occurred in the portal areas, veins, and Glisson's capsule and were characterized by both active and chronic forms of inflammation. Abundant infiltrates of eosinophils and plasma cells often marked the portal areas. Endophlebitis, with or without thrombosis, was the predominate vascular lesion. The flukes recovered varied greatly in size (6.5 to 48.0-mm long) and demonstrated some sexual development, but none was sexually mature.

Hematological, biochemical, histoenzymological, and histopathological changes in serum and tissues were studied in chickens during outbreaks of nephritis. Hematological studies revealed normocytic-normochromic anemia characterized by increased total erythrocyte counts, hemoglobin, packed cell volume, and erythrocyte sedimentation rate. Albumin-to-globulin ratio and sodium levels in serum, glucose in blood, and alkaline phosphatase and glucose-6-phosphatase in liver and kidneys were decreased. Glutamate pyruvate transaminase, uric acid, non-protein-nitrogen, and potassium levels in serum were increased. No significant change in the calcium, phosphorus, and total protein levels in serum was observed. These changes were directly related to the severity of the nephritis.

The reproducibility of the studied biochemical methods was determined by means of the criterion of dispersion of the results approaching the average arithmetic value--the coefficient of variance 'V'. A total of thirty analyses per series were made of one and the same sample, under one and the same conditions, by one and the same laboratory assistant. The blood plasma of cows was studied spectro-photometrically with regard to the levels of urea, total protein, sialic acids inorganic phosphorus, carotene, cholesterin, alkaline phosphatase, aldolase, GOT, GPT, and whole blood (for blood sugar). Complexonometrically, blood plasma was studied for total calcium and magnesium. Flame-photometrically, blood plasma was studied for the content of potassium and sodium; these elements were also followed up in erythrocytes and urine of cows as well as in semen of boars. Employed were methods that were routinely used within the system of the Research and Productional Veterinary Union as suggested by Tsvetkov et al. in their Manual of Methodical Guidance. The values of the coefficient of variance for the variance series of each index were compared to the admissible boundary of V (AB-V) as calculated by Tonks' method. Stated are the sources of mistakes for each of the methods tested, and possibilities are sought to optimize the values of V through eliminating accidental errors.(ABSTRACT TRUNCATED AT 250 WORDS)

The biochemical profile [levels of calcium, phosphorus, magnesium, chlorides and iron, the activities of alkaline phosphatase (ALP), aspartate aminotransferase (AST) and alanine aminotransferase (ALT), and the concentrations of total protein, albumin, cholesterol, urea, glucose, and vitamins A and E] was studied in the blood serum of 40 anoestrous and 40 control inseminated animals in a production herd with an increased occurrence of anoestrus in gilts. The anoestrous gilts showed significantly lower levels of albumin (P less than 0.01) and glucose (P less than 0.01) and ALP activity (P less than 0.05), and significantly higher concentrations of urea (P less than 0.01), vitamin A (P less than 0.01) and vitamin E (P less than 0.05) and ALT activity (P less than 0.05), as compared with the inseminated controls. An extended enzymatological examination consisting of the evaluation of the activities of ALP, AST, ALT and gamma-glutamyl transferase (GMT) was performed in another set of 22 anoestrous and 20 mated gilts. The anoestrous gilts showed a statistically significant increase in the activities of AST (P less than 0.01), GMT (P less than 0.01) and ALT (P less than 0.05) and an insignificant increase in the activity of ALP in comparison with the control animals. The comparison of the obtained values of the studied biochemical criteria with literary data indicated a lower concentration of magnesium and a higher ALP and ALT activities in the anoestrous and inseminated gilts in both groups under study. A high acidity of fat and a medium to high fungus infestation (Mucor sp., Aspergillus sp.) were found by chemical and mycological examination of the administered feed mixtures. The histological examination of the ovaries of anoestrous animals showed cystically degenerative changes, proliferations of fibrous elements, and partial atrophy of ovarial cortex. It has been inferred from the observations that mycotoxins may be involved in the increase in the occurrence of anoestrus, either by a direct effect on sexual organs or by impairing the function of liver which, secondarily contributes to the rise of ovarial dysfunctions.

Sixty-seven clinically healthy mature coypus were studied for some biochemical values in blood, 25 coypus were examined for the distribution of serum proteins and 20 ones for haematological values. Blood was sampled when the animals were killed and was examined by current laboratory methods. In comparison with the other animals, coypus had higher values of phosphorus and magnesium, and lower values of total protein and gamma globulins. The activity of enzymes (AST, ALT, GMT, ALP) was at the same level as in the other animals. Lower values of haemoglobin were found in coypus; the remaining haematological values are close to those in the other animals.
