A 10-year old girl (34.5 kg) being treated at our clinic for osteomyelitis erroneously received an overdose of lincomycin. On a single day she was given 2 infusions containing 6 g of lincomycin each, which corresponds to a dose of 343 mg/kg of body weight. There was an interval of 10 h between infusions. Apart from fatigue and unpleasant taste sensation, she demonstrated no signs of intoxication. None of the laboratory parameters (GOT, GPT, gamma-GT, LDH, G-LDH, LAP, alkaline phosphatase and CK; furthermore, the concentrations of glucose, BUN, creatinine, uric acid and bilirubin) offered any evidence of toxic organ damage. Osteomyelitis in children demands extremely high doses of antibiotics. In view of this fact, the therapeutic range of a substance is of utmost clinical interest.

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.

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.

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.

Piritramide with chlorpromazine in doses of 3 mg kg-1 of live weight causes total anesthesia the intensity of which differs according to the breed and condition of the individual. Anesthesia sets in in 30 to 45 minutes and lasts for 3/4 to 1 1/2 hour. During the anesthesia somatic temperature and frequency of pulse decrease, and even after 24 hours they do not reach the original values. In a majority of cases breathing frequency rises insignificantly, and after 2 to 3 hours it returns to the normal. In single cases there occurs an extreme increase of the number of respirations. The per minute breath volume in the various cases and measurings differs considerably. In the course of anesthesia there occurs an increase of glucose, a decrease of the total protein, an increase of the activity of GPT and GOT, a decrease of the numbers of erythrocytes, of haematocrit and haemoglobin, an increase of pCO2 of the blood, and a decrease of the actual pH of the blood. In the number of leucocytes no changes occurred. The changes in the BE were insignificant. All deviations, except the deviations of the pulse and of the temperature, return to the original values within 24 hours. In the ECG there occurred a fluctuation in the forming of emotions and changes of the amplitude values of the QRS group and of the T wave. In the EEG striking periodical complexes of slow waves were found or combinations of slow and rapid frequencies.

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.

Protein hydrolysate-containing parenteral solutions have been reported to be hepatotoxic. Ten infants who were treated with a 20 percent glucose solution containing either 2.5 percent or 3.25 percent protein hydrolysate are reviewed. Their gestational ages were 30 to 40 weeks and births weights 1000 to 35000 g. Serum glutamate-oxaloacetate transaminase (GOT), glutamate-pyruvate transaminase (GPT), leucine amino peptidase (LAP) and bilirubin were measured serially. Serum amino acids were measured and consistently demonstrated decreased levels of isoleucine and increased aspartic acid, glutamic acid, serine, proline, glycine, alanine, threonine and lysine. The amino acid imbalances were associated with transaminase elevations in eight infants. Serum bilirubin levels increased in six patients and LAP in four. Liver biopsies from three patients showed minimal to moderate hepatic parenchymal disease with cholestasis.

A series of clinical-chemical tests was conducted in 68 schizophrenic out-patients under long-term neuroleptic medication, with particular consideration of the hepatic metabolism, i.e.: Erythrocyte sedimentation rate, alpha 1-glycoprotein, ceruloplasmin, fibrinogen, GPT, GOT, gamma-GT, total protein and serum-protein-electrophoresis. Furthermore, the glucose tolerance tests was carried out. In 44% of the patients an increased erythrocyte sedimentation rate and positive correlations with increased fibrinogen values were found. Increased gamma-GT-values were proven in 33% of the patients; they correlated positively with the increased GPT-and/or GOT-values as well as with pathological glucose tolerance values. Overweight of more than 10 kilos was found in 46% of the patients. A significant correlation between overweight and pathological glucose tolerance values existed. The results were interpreted as consequence of a light fatty liver.

A description is given of an outbreak of equine infectious anaemia (E.I.A.) in Campania [at Naples and Aversa (Caserta)]; it was diagnosed by clinical, pathological and serological examinations (Coggins test). Using the serum of 45 horses with E.I.A. and 11 healthy horses (controls), numerous investigations were carried out on: enzymes, intrinsic coagulation factors, lipids and other substances. The results obtained were very interesting and show that in this disease there are significant increases in many enzymes (LDH, LAP, gamma-GT, CPK, PK and ALD) and copper. Insignificant increases were found in other enzymes (SDH, GLDH, MDH, ICDH, AIP, lysozyme, cholinesterase, GOT and GPT) and also intrinsic coagulation factors, lipid substances (total cholesterol, esterified cholesterol, triglycerides) and glucose. LDH-1-isoenzyme remains unchanged, whilst AcP decreases slightly.
