After the second and fourth parturition of piglets, ten clinically healthy sows, weaned on the second day of life, were subjected to examination two to three days before heat, during heat (defined by typical changes on the outer genitals and immobilization in the presence of a boar) and two days after insemination. During the morning hours, four hours after the last feeding, blood was taken from V. cava cranialis. Seventeen parameters were determined in whole blood and in the blood serum. In the period of oestrus, compared with the period two to three days before this period and two days after insemination, a marked increase was observed in the concentration of the serum levels of 11-hydroxycorticosteroids, iron, and in the activity of alanine aminotransferase. The activity of aspartate aminotransferase was increased in heat only in comparison with the period of the two days after insemination. The concentration of haemaglobin in whole blood was significantly increased in comparison with the period before oestrus and after insemination. Further, in the heat period -- as compared with the time before it -- a considerable drop was observed in the content of inorganic phosphorus and vitamin A. The possible mechanism of the occurrence of other changes is discussed.

The rats were given subcutaneously CdSO4 in doses 0.7 mg/kg of body weight once a week during one year. After the lapse of 6, 9 and 12 months, the animals were sacrificed and their blood was used to determine the preselected biochemical indices (erythrocytes, hemoglobin, hematocrit, levels of protein, albumins, globulins GOT, GPT, AP and its isoenzymes, calcium, inorganic phosphorus, urea and creatinines). Simultaneously radiological examinations were performed on prepared and dehydrated long bones being estimated. Changes were revealed in morphological parameters of long bones with a marked demineralisation of epiphyses after 9 months of investigations. The above changes were found to correlate with those referring to biochemical indices levels, intensifying with the increase of the exposure period.

Normal values for 13 chemical constituents of plasma were estimated from results for 837 presumably healthy children. Ninety microliters of specimen was analyzed for lactate dehydrogenase, aspartate aminotransferase, alkaline phosphatase, inorganic phosphorus, total calcium, total cholesterol, total proteins, albumin, uric acid, urea nitrogen, alanine aminotransferase, total bilirubin, and glucose. We used two Abbott ABA-100 Bichromatic Analyzers interfaced directly to the ABA Data Management System. For each test age- and sex-related variations were assessed and normal values were estimated for six different age groups.

In order to verify the influence of sampling time on blood constituents, populations of supposedly healthy subjects were grouped according to age, sex, deviation from their ideal weight, state of fasting or nonfasting, and time of sampling. Each fasting subject in one group underwent two samplings during the course of a morning: the first at 08.00 and the second between 09.00 and 12.00. In the second group, the first was taken at 13.00, and the second between 14.00 and 16.00. Subjects in the second group had eaten a standard meal of 700 calories at 12.00. Differences between the paired samples from a given individual are discussed with respect to the time of sampling for plasma urea, creatinine, proteins, albumin, calcium, sodium, potassium, cholesterol, uric acid, chloride ions, phosphate, bilirubin, aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, creatine phosphokinase, alkaline phosphatase, hemoglobin and erythrocyte and leukocyte counts. Variations due to the time of sampling were large for phosphorus, bilirubin, and leukocyte count.

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.

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.

Experiments were carried out with a total of 25 chickens of the Leghorn breed divided into two test groups and one control group. The test chickens were given daily the phosphorus organic pesticides timet and lebaized at rates of 0.05 mg anen mg per kg. The treated birds were kept under observation in the course of 72 days recording their cholinesterase activity (ChEA), serumglutamatoxal-acetate transaminase (SGOT), serumglutamatpyruvate transaminase (SGPT), and alkaline phosphatase (APh), and blood sugar level. It was found that as early as the third day from the beginning of the experiment ChEA dropped abruptly--by 62.72 per cent following treatment with timet, and by 29.26 per cent when treatment was carried out with lebaizid. SGOT and SGPT rose up to the 36th day by 78.74 and 59.42 per cent as against the controls. The blood sugar level increased by 20.44 per cent following the administration of timet, and by 6.95 per cent following that of lebaizid. APh on the 12th day was by 60.84 per cent higher as compared to the initial level in the case of timet, and by 39.15 per cent in the case of lebaizid. Results showed that the continuous giving of phosphorus organic insecticides (timet and lebaized) at low rates to chickens leads to the drop of ChA and the rise of SGOT, GPT, APh, and blood sugar, these changes being more clearly manifested in chickens that have been offered timet.

Investigations were carried out on the serum enzymes, total proteins and some electrolites (potassium and sodium) in eight spleenectomized sheep experimentally infected with Babesia organisms. It was found that babesiasis in sheep was accompanied by a considerable rise in the activity of GOT and GPT (from 80JU up to 260IU and from 4 IU up to 19 IU). The amount of inorganic phosphorus dropped, and that of potassium sodium and alkaline phosphatase showed no changes. It is believed that the changes in the activity of GOT, GPT and inorganic phosphorus depend on the gravity and the duration of the disease and can be used as a criterion in determining the pathologic process.

Because of the difficulties in drawing blood for clinical chemistry in small laboratory animals there exist many methods for sampling blood and the preparation of serum, none of which is generally accepted or well standardised. It was the aim of this study to investigate the effects of sampling techniques on normal values of enzyme activities in the serum of rat and mouse. The activities of the following enzymes were determined: sorbitol dehydrogenase, lactate dehydrogenase, malate dehydrogenase, glutamate dehydrogenase, aspartate aminotransferase, alanine aminotransferase, pyruvate kinase, creatine kinase, myokinase, alkaline phosphatase and leucine aminopeptidase. In addition plasmaproteins, urea and inorganic phosphorus were measured. In rats blood was obtained from the following sites: retroorbital venous plexus, jugular vein, heart and ventral aorta. In mice blood was sampled from the jugular vein and the ventral aorta. Shifts of water from the interstitial to the intravascular space due to hypovolemia occurring during the experimental procedure were followed up by measuring the hematocrit and the distribution of radioiodide labelled albumin. In rats the activities of lactate dehydrogenase, malate dehydrogenase, aspartate aminotransferase, pyruvate kinase, creatine kinase and myokinase found in blood serum obtained from the retroorbital venous plexus and the ventral aorta were too high compared to the other sampling sites. Activities of alkaline phosphatase and alanine aminotransferase were slightly elevated when blood was sampled from the punctured retroorbital venous plexus. Small differences in plasmaproteins and hematocrit values were found to be due to acute shifts of water within the extracellular space. In mice the activities of lactate dehydrogenase, malate dehydrogenase, aspartate aminotransferase and myokinase were found to be too high in blood serum obtained from the ventral aorta. Efflux of enzymes from damaged cells and the interstitial space ive caused erroneous results too, but only to a minor extent. The most reliable method for blood sampling in rat and mouse is the cannulation of the jugular vein. The heart puncture can be recommended too. Attention should be paid, however, to the possibility of aspirating disrupted muscle cells through the inserted needle.

In the serum of 40 male and 40 female rats the following parameters were determined: Sodium, potassium, creatinine, chloride, calcium, inorganic phosphorus, glucose, urea, protein, cholesterol, bilirubin, lipids, alanine amino-transferase, alkaline phosphatase and leucine arylamidase. The analyses were carried out in the same rats both after continuous feeding, and after a 24-hour fasting periods spaced at intervals of 3- to 4-weeks. The concentration of glucose and the activities of alanine aminotransferase and alkaline phosphatase were higher after feeding than after fasting, and in most cases these differences were statistically significant. The concentration of lipids tended towards increased values. The other parameters examined were slightly or not influenced by the time of the foregoing feeding.
