Normal mean values for hematocrit, hemoglobin concentration, erythrocyte and leukocyte counts, hematimetric indices, erythrocyte dimensions, glucose, urea, uric acid, cholesterol, creatinine, total bilirubin, serum aspartate aminotransferase, serum alanine aminotransferase, alkaline phosphatase, creatinine phosphokinase, lactic dehydrogenase, inorganic phosphorus, chloride, total plasma protein, sodium, potassium, calcium, and magnesium were obtained from the blood or plasma of four Masai ostriches (Struthio camelus) when juveniles at 5 mo of age and as adults 1 yr later in the Barcelona Zoo (Spain). Young ostriches had significantly lower concentrations of hematocrit, hemoglobin concentration, calcium, and magnesium, and higher levels of total protein and potassium, than the adult individuals. The rest of the parameters were not significantly different between the two age groups. The data obtained provide reference values for Masai ostriches.

Colchicine treatment was used in this randomized placebo-controlled trial in patients with severe acute alcoholic hepatitis [serum bilirubin greater than or equal to 5 mg/dL (85.5 mumol/L) mean, 17.5 +/- 7.5 mg/dL (299.25 +/- 128.25 mumol/L)]. Hospitalization mortality and morbidity and the effect on biochemical test results were the end points of the treatment. Patients in the two groups were evenly matched by demographics and laboratory test results. Mean time to study entry was less than 7 days from admission. The duration of the trial was 30 days. Thirty-six patients (24 men, 12 women) received colchicine (1 mg orally every morning) and 36 (25 men, 11 women) received an identical placebo. Seven (19%) colchicine-treated and six (17%) control patients died during the index hospitalization after a mean of 17.4 +/- 10.8 and 17.8 +/- 5.3 days, respectively (NS). During a 4-month follow-up period from entry into the trial, there were two additional deaths in each group. No differences between placebo- and colchicine-treated patients were observed in any of the laboratory parameters (serum bilirubin, aspartate transaminase, alanine transaminase, prothrombin activity, albumin, white blood cell count, hemoglobin, and creatinine) that were followed up over the 30-day treatment period. The frequency of complications did not differ statistically between the two groups. This study showed no effect of colchicine treatment on mortality and morbidity of severe alcoholic hepatitis. Colchicine cannot be recommended for the treatment of patients with alcoholic hepatitis.

The distributions of erythrocyte values (red cell count, hemoglobin concentration, etc.) of healthy male workers working in a certain factory were studied in order to evaluate the usefulness of the variables as health indicators. In addition to the estimation of erythrocyte values, anamneses concerning chronic bleeding, smoking habit and alcohol consumption were questioned and serum Fe, Cu, TIBC, ferritin, plasma erythropoietin, and serum enzymes (GOT, GPT, gamma-GTP) were measured. Two-dimensional frequency distributions with axes for the red cell count and hemoglobin concentration, and frequency distributions of the score calculated from principal component analysis, showed bimodal patterns. Using nonlinear curve fitting methods, the distributions of principal component scores were fitted to a mixture of two different Gaussian distributions. The workers were then divided into two groups corresponding to the Gaussian distribution he belongs. Then the frequencies of the items and mean values of the variates were compared between them. There were no differences in the incidences of diseases that caused iron deficiencies, but the mean serum ferritin level was significantly lower in one group than in the other, in other words the workers belonging to the group with low serum ferritin level had smaller iron stores than the other. The mean serum erythropoietin level and the mean serum copper level were higher in that group than in the other. As a result, this analysis gives a new evaluation of the health status of a man who belongs to the so-called healthy male group.

Theophylline administration to seven healthy male volunteers resulted in a rapid and significant decline in both plasma and erythrocyte pyridoxal-5'-phosphate levels. Total erythrocyte pyridoxal kinase levels increased during 15 wk of theophylline treatment from a mean initial activity of 19.23 +/- 5.03 (mean +/- SD) to 62.64 +/- 11.59 nmol pyridoxal-5'-phosphate formed/(g hemoglobin.h). Although plasma pyridoxal levels remained normal, the threefold increase in total erythrocyte pyridoxal kinase activity levels did not normalize plasma and erythrocyte pyridoxal-5'-phosphate levels. Pyridoxal-5'-phosphate hydrolysis was not affected by theophylline therapy. Increased pyridoxal oxidation was confirmed by elevated urinary 4-pyridoxic acid excretion after 15 wk of theophylline treatment. Mean erythrocyte alanine aminotransferase activity declined by 70%, and aspartate aminotransferase activity declined by 50%, indicating that decreased availability of pyridoxal-5'-phosphate can have widespread metabolic consequences. We conclude that the effect of theophylline on vitamin B-6 metabolism is not transitory and cannot be overcome by elevated intracellular levels of pyridoxal kinase. However, pyridoxine supplementation (10 mg/d for 1 wk) normalized indices of vitamin B-6 status and reversed the downward trend in both alanine aminotransferase and aspartate aminotransferase activity levels.

A daily dosage of vanadate (0.9 mgV/kg) injected subcutaneously for 16 days to adult rats produced significant changes in blood cells and serum elements. The hematological changes included an increase in white blood cell count at two days after the last injection. At five days, red blood cell count (RBC), hemoglobin, and packed cell volume (PCV) were low. At 12 days, there were reductions in RBC, hemoglobin, PCV, and lymphocyte counts and an increase in polymorphonuclear cell (PMN) counts. At 25 days, RBC, hemoglobin, and PCV were still low. At 40 days, the only change was a reduction in RBC. Changes in the serum at two days posttreatment were a reduction in lactic dehydrogenase activity (LDH), alkaline phosphatase activity (AP), calcium, albumin, and total protein and an increase in cholesterol. At five days, glutamic-oxalacetic transaminase (GOT), lactic dehydrogenase (LDH), inorganic phosphate, and total protein were low and calcium was high. At 12 days, GOT, glutamic-pyruvic transaminase (GPT), and LDH were reduced, and the levels of calcium and cholesterol were elevated. At 25 days, there was a reduction in GPT and LDH and an increase in glucose, calcium, and albumin. At 40 days, the levels of GOT, LDH, AP, and inorganic phosphate were still low. Vanadate at lower dosage levels (0.3-0.6 mg V/kg per day for 16 days) also produced significant changes in blood cellular and serum elements but at lesser degrees of severity. These findings show that the exposure of rats repeatedly to low levels of Vanadate caused anemia, elevation in blood cholesterol levels, and a reduction in serum enzymes activities.

We employed cross circulation (CC) as an assist method for canine orthotopic cardiac transplantation in 8 dogs to obtain long term survivals. Hematological and biochemical examinations were performed intra- and postoperatively, to estimate usefulness of CC. The support dog weighted about 3 times as much as the recipient dog. Using different anesthesia, the systolic pressure of the support dog and the pressure gradient between the support and recipient were kept above 150 mmHg and 50 mmHg, respectively. Cyclosporin and prednisolone were administered for immunosuppressive therapy. All could be extubated on the 1st to 3rd postoperative day, and 6 survived more than 2 weeks. During the operation under CC, changes of LDH and lactic acid were much less, no free hemoglobin was detected, and total protein and hematocrit remained well compared with operation under heart-lung machines. CRK, CPKMB, GOT and GPT increased shortly after operation, but returned to the preoperative values within 2 weeks. In CC, owing to avoidance from mechanical destruction of red blood cells, coagulation disorders and hemodilution, hemolysis and hemorrhage could be decreased, and oncotic pressure remained well, and no severe damage occurred in the recipient organs. Thus, CC is useful as an assist method for canine orthotopic cardiac transplantation.

The primary cause of death following i.v. injection of the basic phospholipase A2 (PLA2) from Naja nigricollis venom has been attributed to its direct cardiotoxicity. In view of our recent findings that cardiac failure caused by the basic PLA2 from Naja m. mossambica is primarily due to hyperkalemia resulting from cellular damage and possibly also from hemolysis, the cause of death due to the basic PLA2 from Naja nigricollis was re-investigated. In the anesthetized mice and rats, the PLA2 (0.3 micrograms/g, i.v.) produced a transient hypotension followed by recovery and subsequently by cardiac failure with ECG changes suggestive of hyperkalemia, such as P-R prolongation, tall T-wave, biphasic QRS-T complex, low voltage of QRS, A-V block, etc. Analysis of blood chemistry revealed marked increases in the plasma levels of K+, CPK, LDH, GOT, GPT, inorganic phosphate and hemoglobin (probably a mixture of hemoglobin and myoglobin). In the atrial preparation, however, no marked cardiotoxicity was observed except for a slight negative inotropic effect at 30 micrograms/ml. When 200 micrograms of the enzyme was injected into the coronary circulation in the Langendorff preparation, also no marked cardiotoxic effect was observed except for a decrease (about 40%) of coronary flow. From these results, it is concluded that the primary cause of death following i.v. injection of the basic PLA2 from Naja nigricollis is apparently cardiac failure due to hyperkalemia, resulting from cellular damage and possibly also from hemolysis, rather than direct cardiotoxicity.

In this paper, the practicability of a quick diagnostic laboratory test to perform blood analysis in healthy pigeons was tested. The Reflotron manufactured by Boehringer Mannheim, works on a dry chemical basis, consists of a reflectance photometer and the accompanying test strips, is easy to use, and yields the result of the desired parameter in a maximum of three minutes. As test material plasma and serum were used. At the time the equipment was tested, test strips for glucose, cholesterol, hemoglobin, triglycerides, urea, uric acid, GOT, GPT and G-GT were available on the market. The usual laboratory "wet chemical" analysis procedures were used to compare the results. The obtained measurements were analyzed using describing and concluding statistics. The influence of gender, feed and time of day on the nine parameters was also considered.

1. The hematology and blood chemistry of 15-68-day-old chicks have been studied. 2. Red cell numbers (1,900,000/mm3), hemoglobin content (11.5 g/dl) and hematocrit (37.5) were similar in both species of storks. 3. Total numbers of leucocytes (63,000/mm3) were similar in both species, whilst differential leucocyte counts were not. 4. Higher levels of plasma protein, GOT and cholesterol in HDL were found in white storks when compared with black storks but not differences were detected in plasma levels of triglycerides, total cholesterol, urea, uric acid, GPT and alkaline phosphatase.

Serum osmolalities and osmolar gap were determined in 43 normal healthy beagles (control group) and 40 dogs with dirofilarial hemoglobinuria (hemoglobinuria group). In the control group, the measured and calculated serum osmolality levels were in the means of 296 +/- 5 (SD) mOsm/kg and 293 +/- 6 mOsm/kg respectively, showing an osmolar gap less than 10 mOsm/kg. In the hemoglobinuria group, the measured serum osmolality ranged from 272 to 370 mOsm/kg. A considerable number of dogs had normal serum osmolalities in spite of severe intravascular hemolysis, suggesting that the changes in serum osmolality would not be the direct cause of intravascular hemolysis. The measured serum osmolality (331 +/- 28 mOsm/kg) was significantly higher in 11 dogs which died after a surgical removal heartworms than in 29 dogs which recovered after the removal (302 +/- 17 mOsm/kg). The calculated serum osmolality level was 296 +/- 16 mOsm/kg in 24 recovered cases, and 304 +/- 22 mOsm/kg in 10 fatal cases. The osmolar gap stayed in the normal ranges of 5.4 +/- 5.9 mOsm/kg in recovered cases, but it attained a higher level of 22.7 +/- 8.9 mOsm/kg in fatal cases, suggesting poor prognosis in cases with large osmolar gaps. There were significant positive correlations between the measured serum osmolality and osmolar gap, serum sodium, potassium, BUN, GOT, GPT, creatinine, bilirubin and plasma hemoglobin values, as well as between the osmolar gap and serum potassium, BUN, GOT, GPT, creatinine and bilirubin values. The plasma hemoglobin concentration fell markedly without significant change in serum osmolality 20 hr after the heartworm removal.
