Blood urea content and the serum concentrations of sodium, creatinine, uric acid, glutamic oxaloacetic transaminase (g.o.t.), glutamic pyruvate transaminase (g.p.t.) and bilirubin were measured before delivery, on the 2nd and 3rd days and on the 5th day after delivery. In two groups of mothers, one receiving nitrous oxide analgesia and the other a combination of nitrous oxide and methoxyflurane, blood urea and serum sodium and g.o.t. were increased following labour and nitrous oxide analgesia; s.g.p.t. was increased only in the late post-partum period. Serum sodium, creatinine, uric acid, urea, g.o.t. and g.p.t. increased following exposure to methoxyflurance. The increase in serum sodium, uric acid and urea was dose-dependent. Capillary concentrations of uric acid in the neonates showed dose-dependent changes in response to methoxyflurane.

One hundred and sixteen colony control dogs (purebred beagles) ranging in age from 56 to 4868 days at the time of sampling, were tested at various intervals over a 10-year period to determine the normal values of several serum constituents. The effects of sex and family line were also noted. With increasing age, serum glutamic-pyruvic transaminase, total protein, and cholesterol increased, whereas glucose, serum glutamic-oxalacetic transaminase, creatine phosphokinase, iron, alkaline phosphatase, and albumin decreased. Females had significantly higher levles of urea nitrogen, iron, and cholesterol than males. Males had significantly higher serum glutamic-pyruvic transaminase levels. The rate of increase in serum cholesterol with age was greater in males than in females. Males showed no age related changes in levels of urea nitrogen or iron, while the females showed decreasing levels. Significant differences in total protein and albumin were noted in dogs belonging to different family.

The extent of liver and kidney damage in 10 young steers, infected with a stabilate of Theileria annulata, was estimated by the determination of enzymes (GOT, GPT, SDH, ALD), serum levels of bilirubin and urea. At the same time the effectiveness of some liver protecting medical agents was tested. The following results were obtained: Change in the activity of the enzymes GOT, SDH and ALD and the increase of bilirubin during the advanced course of the disease are indicative of severe tissue damage in the liver. The levels of urea were found to be in the normal range with only a few exceptions. This seems to exclude the involvement of the kidney in the disease. The group of animals receiving liver protecting medication did not show any difference compared with those animals without medication.

Adenylosuccinase activity of rat liver is depressed by prolonged starvation, cortisol administration, high protein diets, and alloxan diabetes. The loss of activity is not due to the accumulation of a dissociable inhibitor or loss of a cofactor. Starvation produces no loss in activity for 1 day; thereafter the activities of the liver and spleen enzyme decay with a half-life of about 0.9 day. Starvation produces no change in the activity of the kidney, brain, and skeletal muscle enzyme. Refeeding restores the activity of the liver enzyme to the fed level, with only a slight overshoot. The recovery of adenylosuccinase activity is equally rapid after refeeding a balanced diet, or corn oil, or glucose, and is not inhibited by injection of glucagon, in contrast to malic enzyme activity. Recovery is inhibited by cycloheximide, indicating the involvement of protein synthesis. Althouth adenylosuccinase is depressed in liver of starving rat it is elevated in liver of starving chicken. Starvation depresses malic enzyme activity and elevates alanine aminotransferase activity in both species. When rats are starved, the rate of de novo synthesis of adenine mononucleotide decreases in spleen and liver but not in kidney, suggesting a regulatory role for adenylosuccinase in purine biosynthesis. The low activity of adenylosuccinase in liver of severely starved rats is inconsistent with the proposal (Moss, K. M., and McGivan, J.D. (1975) Biochem. J. 150, 275-283) that the purine nucleotide cycle plays a major role in ammonia production for urea synthesis, at least under these conditions.

Blood serum samples were obtained from 114 crossbred calves on a feed trial under feedlot conditions at the end of a 56-day feeding period. Average values for 19 blood components were determined. The effects of the 3 trial rations and 2 electrolyte treatments were analyzed. Except for inorganic phosphates, urea nitrogen, cholesterol, glucose, alanine aminotransferase, and alkaline phosphatase most mean values were similar to those in dairy cattle. Urea nitrogen values differed significantly (P less than 0.05) in animals fed different rations apparently reflecting the crude protein content of each ration. The mean values presented can be used as base-line data for comparison with other similar studies or with values from diseased animals.

Twenty biochemical parameters have been studied in 94 athlets of Marcialonga in basic conditions and after 30 min from the end of the competition. Urea, uric acid, creatinin, total proteins, albumin, sodium, calcium, phosphorus and several enzymes (AST, ALT, LAD, CK and ALP) have shown statistically significant increasings. It is, above all, clear the increasing of CK. On the contrary triglycerides have undergone a significant decreasing. The AA. try to explain the results obtained, considering some pathogenetic theories.

In a series of experiments with a total of 1480 veal calves, different aspects of treating calves with anabolic steroids were examined. The anabolics used were 17beta-estradiol (E), trenbolone acetate (T), progesterone (P), testosterone (Te), C+T, E+P, E+Te and zeranole (Z). The N-retention was estimated by examining the urea: creatinine ratio in single urine specimens during the course of two feeding trials. Increased gain due to the treatment with E (20 mg implanted/calf) + P (200 mg) and Te (200 mg), respectively, E + T (140 mg) or Z (36 mg) was during the whole experimental period. The extra gain, due to anabolics seems to contain even more protein. This conclusion may be supported by the crude protein content of meat samples. The antibody production of a total of 311 male and female calves was investigated after the application of the following steroids: E (20 mg), T (200 mg), T (200 mg), E + T, P (200 mg), Te (200 mg), E + P, E + Te, and Z. Eleven days after the implantation of the steroids the animals were immunized with alumprecipitated human serumalbumin. Antibody-titres were determined by the Antigen-Binding-Capacity Test on day 14 following immunization. In nearly all groups the antibody-titres of female calves exceeded those of male calves on the average by 75%. The immune response of all experimental groups did not differ significantly from that of the corresponding control groups. However, the results indicate that both E + T and its single components E and T exert an immunodepressive effect in male calves. While the humoral antibody formation in the calf appears not to be influenced by anabolic steroids, it cannot be decided presently whether these substances effect cell-mediated immune reactions and/or unspecific mechanisms of resistance. When estradiol (20, 200, and 500 mg) and trenbolone acetate (140, 1400, 3500 mg) alone and in combination were implanted in female calves, blood glucose, GOT, GPT, alkaline phosphatase, LDH, cholesterine and bilirubine; Hb, PVC, quick value; urine density and pH were not affected by treatment. Some criteria of the mineral metabolism (Ca- and P-levels in serum and bone) was not altered by treatment. Trenbolone (1 400 and 3 500 mg), especially with estradiol, caused a decrease of the serum Mg-level and of the Mg-deposition in the bone. It is discussed that Trenbolone affects the dig-metabolism of calves. Some morphological findings are worth mentioning. The weight of uterus was not affected by the different doses of E or T, but a combination E + T led to a surprising weight increase. The proliferation of uterine glandular cells was responsible for the increased uterine size. The lumen of uterus was partially filled with a watery liquid. The reduction of the ovarian weight was accompanied by a diminution of follicular size for all treated calves, most evident for E (200, 500 mg) + T (1400, 3500 mg). A decrease in the number of follicles was also found for these two groups. T (3500 mg) caused an abnormal size of the clitoris and led to a reduction of the size of thymus.

Commercial feed mixture was buffered with a 2% and 3% admixture of bentonite buffer in two beef cattle herds in the course of one year. The mixtures were fed on a continuous basis. The two-per-cent buffer concentration was tested in 110 test animals with 104 control animals and the three-per-cent concentration in 50 test animals with 50 controls. Throughout the trial the over-all health condition remained unchanged, the hematocrit and hemoglobin values were balanced in both groups. The biochemical indices were better in the test groups: hypocalcemia improved (in the controls it grew worse), magnesiemia was slightly increased, the inorganic serum factor did not go beyond physiological limits, and acidosis did not occur (as distinct from the control animals). The levels of transaminases (GOT, GPT), glutamic acid dehydrogenase, total serum protein, alkaline phosphatase as well as ammonia and urea in blood serum were at physiological values with po-differences within groups. In the case of the three-per-cent buffer concentration the daily gains were higher by 0.073 kg, and in the two-per-cent concentration by 0.058 kg, in the test animals. The average annual gain was higher by 25.5 kg, and by 18.3 kg, respectively. With respect to the price of buffer and to the efficiency of the animals tested, the economic indices of feed mixture buffering are highly effective.

Forty-seven male Macaca mulatta, 3 to 4 kg weight, were inoculated intravenously or subcutaneously with various doses of yolk sac-grown Rickettsia rickettsii. Thirty-four macaques became febrile and exhibited signs of infection ranging from transient illness with a few days of fever to severe illness with subsequent death. The rash appeared more frequently in the macaques inoculated subcutaneously. Febrile macaques that survived had leukocytosis, with concomitant neutrophilia. Febrile macaques that died had, in addition, marked terminal leukopenia and thrombocytopenia. Packed cell volume of all febrile macaques decreased. In almost all of the febrile macaques, there were increased serum urea nitrogen, glutamic-oxaloacetic transaminase, and lactate dehydrogenase and decreased total serum protein and amylase concentrations. A few febrile macaques had increased bilirubin values and decreased sodium, chloride, phosphorus, and alkaline phosphatase concentrations. Changes did not occur in serum glucose, potassium, calcium, and glutamic-pyruvic transaminase values. The experimental form of Rocky Mountain spotted fever in the macaque provides a subhuman primate model for studying the pathophysiology of this disease.

This paper reports a study of changes in red blood cell enzymes and some serum parameters during and after treatment of protein-calorie malnutrition. The red cell GSH levels were low during the crisis, together with the levels of GSSG:NADPH reductase, GSH:H2O2 peroxidase, aspartate aminotransferase and alanine aminotransferase. After treatment the levels of all these enzymes increased significantly to normal values. Of the serum parameters investigated, significant reduction in the activity of the enzymes cholinesterase, catecholamine oxidase, total proteins, albumin, urea and electrolytes were obvious, and returned to normal values after treatment. Ceruloplasmin activity remained low even after three weeks' treatment and could not be related to copper levels. The results are discussed in relation to anemia and liver damage that may accompany the syndrome.
