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.

Fifty-one leprosy patients receiving long-term clofazimine have undergone systematic clinical laboratory testing in a search for any toxicity secondary to the drug. In approximately 220 patient-years of observation and in analyzing approximately 40,000 test results, no statistically significant changes in the direction of abnormality have been observed in SGOT, thymol turbidity, serum globulins, uric acid, alkaline phosphatase, white blood cell count or differential, hematocrit, hemoglobin, BUN, serum creatinine, serum cholesterol, serum albumin, serum potassium, serum calcium, stool for occult blood, routine urinalysis, or reticulocyte count. Statistically significant changes toward abnormality were found in fasting blood sugar and total serum bilirubin. These statistically significant changes in the direction of abnormality were of a small magnitude, were not associated with related clinical signs or symptoms, and do not seem to be of major clinical significance. Despite the accumulation of relatively massive amounts of the drug in various tissues, clofazimine appears remarkably free of serious or life-threatening toxicity clinically. Although the skin and gastrointestinal side effects of clofazimine limit its usefulness, on the evidence to date, its advantages outweigh its disadvantages in those leprosy patients for whom it is indicated.

The dog jejunum is a much denser tissue than the ileum, with a greater weight per unit length and higher proportion of mucosal tissue. Morphometric analysis reveals longer and wider villi, deeper crypts and larger enterocytes in the jejunal mucosa. Uptake of phenylalanine or beta-methyl-glucoside by tissue slices in vitro is slightly greater in jejunal than in ileal tissue. The levels of acid phosphatase and alkaline phosphatase in the individual enterocytes are significantly greater in the jejunum, according to quantitative histochemical analysis. The absorption of water, sodium, potassium, chloride and glucose in vivo is significantly smaller in the jejunal than in ileal loops, particularly when expressed in terms of unit mucosal weight. Sodium and water absorptions are stimulated by glucose at both sites, but the stimulation is significantly greater in the ileum. Opposite results have been obtained in rats where the transport of phenylalannie in vitro is greater in the ileum, but water, electrolyte and glucose absorption in vivo is greater in the jejunum.

Copper was accidentally introduced into seawater entering a circular outdoor tank used to culture 610 pinfish (Lagodon rhomboides) and other marine teleosts. Fish were exposed for 23 hours to copper concentrations between 0.2 parts per million (ppm) and 7.2 ppm with an average concentration of 3.3 ppm. The pinfish were lethergic by 6 hours after copper was introduced into the tank. Deaths began within 10 hours with a total of 575 (94%) deaths. Deaths stopped 11 hours after copper concentrations decreased below 0.2 ppm and signs of distress stopped in surviving pinfish by approximately 6 hours after the last death. Serum urea nitrogen, alkaline phosphatase, sodium (Na+), and potassium (K+) concentrations were increased and represent those constitutents which differ from mean control values by more than 2 standard deviations. Electrolyte imbalance, apparently resulting from impaired osmoregulation and hemolysis, was a serious terminal condition in copper-poisoned pinfish.

The values of a number of biochemical variables have been studied before and after a 50-gram load of glucose orally. Reductions which were statistically significant were found for sodium, potassium, urea, total protein, albumin, calcium, phosphorus, urate, bilirubin, alkaline phosphatase, but not for bicarbonate, creatinine, creatine kinase, lactate dehydrogenase, aspartate aminotransferase, cholesterol, triglyceride or chloride. The magnitude of the changes was generally not great, but could be clinically appreciable. The differences may need to be taken into account in comparing population studies.

The advent of high-capacity multi-channel analyzers allows estimation of long-term variability in serum constituents of large numbers of subjects. By frozen storage of specimens with subsequent analysis in a single machine run, long-term analytical variation may be eliminated, thus sharpening the estimates of intra-individual variation. In the present study we used the Vickers M-300 analyzer to obtain the data for such estimates from 37 male volunteers, each bled once a week for 22 weeks. Secimens were analyzed in random order to eliminate any biasing effect of analytical drift during the 4-h machine run. Ten serum constituents were measured. Storage-induced linear trends were small or negligible during the period of specimen collection. Using the ratio of average within-subject variance to the variance among subjects as a guide, serum alkaline phosphatase was found to show the greatest individuality, sodium and potassium the least. Other constitutents showed varying degrees of individuality, but for all these analytes, the usual population-based reference ranges were found to be either insensitive or irrelevant to the study of concentration changes over time within most healthy subjects. Our results generally confirmed those of smaller but comparable earlier studies.

Dexamethasone (4-8 mg/m2 body surface area) was given orally or intravenously to six normal volunteers. The maximum neutrophil count occurred 4-6 h after oral or intravenous administration of dexamethasone and was due almost entirely to an increase in mature neutrophils; concomitantly there was a lymphocytopenia. A second rise in the neutrophil count occurred 24 h after oral ingestion of dexamethasone, coinciding with a lymphocytosis. Neutrophil alkaline phosphatase (NAP) activity during development fell as the neutrophil count rose. Other haematological values were unchanged except for small increments in erythrocyte sedimentation rate (ESR). Sodium concentration in serum and urine remained normal but urinary potassium excretion and urine volume increased after the intravenous dose. There was a direct relationship between plasma concentration of dexamethasone and the rise in neutrophil count following intravenous but not oral administration. The concentration of dexamethasone in plasma fell to half its peak value in 2-6 h. Dexamethasone-induced neutrophilia was similar to that induced by other corticosteroids. Dexamethasone in a dose of 6 mg/m2 produced minimal discomfort while inducing an adequate neutrophilia in the volunteers.

The stability of total protein and various enzyme and electrolyte analytes in numerous pools of lyophilized quality control sera is evaluated. Using data obtained between 1973 and 1976 from Regional Quality Control Programs utilizing the Quality Assurance Service of the College of American Pathologists, monthly group mean values are studied as a function of time, by means of linear regression analysis. In the 28 pools studied, unstable analyte-pool combinations were detected in approximately 35% of the cases. Total protein was the most universally stable. In a large percentage of pools, minimally increasing concentrations of sodium, chloride, and potassium were found, while inorganic phosphorus decreased in the majority of pools. In pools with changing enzymatic activiteis, alkaline phosphatase tended to increase and creatine phosphokinase generally decreased. Changes in levels of calcium, serum glutamic oxaloacetic transaminase, and lactate dehydrogenase were inconsistent. Changes in analyte concentration were judged in relation to the precision (SD) with which the analytes were measured. The ratios of rate of change in analyte value to SD were lower for electrolytes than for other analytes.

Urethral obstruction induced in adult male cats caused clinical signs identical with those observed in naturally occurring disease. Central nervous system depression, anorexia, dehydration, vomiting, muscle weakness, and hypothermia occurred. Weight loss (due to water loss and catabolism), metabolic acidosis, mild hyponatremia, hyperkalemia, hypermagnesemia, hypocalcemia, hyperphosphatemia, hyperglycemia, azotemia, and hyperproteinemia were also observed. Serum amylase, alkaline phosphatase, and alanine aminotransferase activities were normal. Ten of 13 cats (group 1), with 72 hours' induced obstruction but not treated with parenteral fluids, died either before the obstruction was relieved or within 8 days afterward. Eight cats (group 2) with induced obstruction for 49 to 98 hours developed severe clinical and biochemical alterations. Treatment with a multiple-electrolyte solution, in addition to relief of urethral obstruction, resulted in favorable clinical and biochemical responses. These cats survived and were clinically healthy at 9 to 10 days after relief of obstruction. It was concluded that use of a multiple-electrolyte solution to correct acidosis, restore circulatory volume, and enhance renal excretion of potassium was effective supportive therapy after urethral obstruction was removed.

The effects of prolonged strenous exercise on the plasma concentrations of sodium, potassium, calcium, chloride, bicarbonate, phosphate, albumin, cholesterol, glucose, creatinine, bilirubin, alkaline phosphatase, creatine phosphokinase, lactic dehydrogenase and asparate amino transferase were studied in a group of 26 horses competing in an endurance ride. There were significant changes in most parameters, when control values were compared with those taken immediately after the ride. There was also a significant correlation between several biochemical parameters and heart rate taken 30 minutes after the ride. When faster and slower horses were compared, significant differences were found only in phosphate and glucose values.
