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.

In order to assess the functional state of the liver in 45 repair service workers of a chemical plant producing pesticides the serum concentration and electrophoretic pattern of proteins, the concentration of bilirubin and the activity of alkaline phosphatase, gamma-glutamyl- transpeptidase, alanine and aspartate aminotransferase, and lactic and malic dehydrogenase were determined. As compared to 35 healthy controls, not exposed to noxious chemicals, a significantly lower serum protein concentration with higher percentage of gamma-globulins and lower albumins and alpha 2-globulins were observed, the serum alanine and aspartate aminotransferase activities were significantly elevated. Ultrasound examination of the hepatic structure revealed liver steatosis in 11 (24.4%) workers. The results of our study point to a discrete lesion of the liver.

The critical difference, which may help to judge whether the difference between two consecutive analytical results may be safely ascribed to natural variation or not, was calculated for 12 clinical chemical components determined in blood samples collected once a week for 5 consecutive weeks from 19 clinically healthy Red Danish dairy cows. For each clinical chemical component, the total variance of the analytical results was divided into the component of variance between cows (S2Inter), the component of variance for weeks within cows (S2Intra) and the component of variance for measurements (S2Anal) using nested analysis of variance. The critical difference calculated in absolute values from S2Intra and S2Anal was 0.15 mu kat per 1 for alanine aminotransferase, 0.55 mu kat per 1 for aspartate aminotransferase, 0.57 mu kat per 1 for alkaline phosphatase, 0.14 mu kat per 1 for gamma-glutamyltransferase, 1.95 mu kat per 1 for creatine kinase, 2.23 mmol per 1 for urea, 22 mu mol per 1 for creatinine, 2.4 g per 1 for albumin, 10.0 g per 1 for serum protein Total, 0.71 mmol per 1 for glucose, 0.54 mmol per 1 for calcium and 0.25 mmol per 1 for magnesium. These critical differences may be used as guidelines to evaluate the difference between two consecutive analytical results in cows. However, the analytical results should not be assessed by the critical differences alone, but should also be compared with the corresponding reference intervals.

The influence of Ukrain on the activity of aminotransferases (ALT and AST) and on the serum total protein content was estimated in mice and rats of both sexes receiving single or repeated doses of the drug. It was found that one hour after intraperitoneal (i.p.) administration of Ukrain no characteristic changes were recorded in the activity of the investigated enzymes, or in the serum protein content of animals of either sex. Similar effects were observed after three months treatment with Ukrain in rats of either sex. Only in mice receiving Ukrain for three months was a rise in ALT and AST activity found. No particular changes were observed in the total serum protein level, except for a small decreases in the sera of male mice.

A 2 x 2 x 2 factorial arrangement of treatments consisting of dietary aflatoxin (3.5 micrograms/g), ochratoxin A (2.0 micrograms/g), and hydrated sodium calcium aluminosilicate (HSCAS, .5%) was used to evaluate the individual and combined effects of these treatments. There were six replicate pens of 10 broilers per pen for each of the eight treatments. The broilers were maintained on these treatments from 1 day to 3 wk of age with feed and water available for ad libitum intake. Aflatoxin and ochratoxin A each significantly decreased body weight, serum protein, albumin, and cholesterol and increased the relative weight of the liver, kidney, and proventriculus. Aflatoxin increased the relative weight of the heart and decreased serum aspartate aminotransferase activity and ochratoxin A increased serum uric acid. The toxicity resulting from the combination of aflatoxin and ochratoxin A was more severe than when either of these mycotoxins were present alone. Addition of HSCAS alone did not alter any of the parameters evaluated. The HSCAS reduced the toxicity of aflatoxin, but had little effect on either the toxicity of ochratoxin A alone or the toxicity resulting from the combination of aflatoxin and ochratoxin A.

Total serum protein, serum albumin, total urine protein excretion, and the serum activity of several enzymes--aldolase (ALS), cholinesterase (CHS), leucine aminopeptidase (LAP), isocitrate dehydrogenase (ICD), aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), alpha-hydroxybutyrate dehydrogenase (HBD), creatine kinase (CK), alkaline phosphatase (ALP), and gamma-glutamyl transferase (GGT)--were estimated in rats with nephrotic syndrome (NS) at 2, 4, 6, 8, 10, 12, 16, 20, and 30 days after a single injection of puromycin aminonucleoside (PAN). It was found that: (a) total serum protein and serum albumin diminished on day 4 and returned to control values on days 20 and 30, respectively; (b) total urine protein excretion rose on day 4, reached a peak value on day 8, and then fell substantially but still remained higher than control values on day 30; (c) ALS and CHS activities increased; (d) LAP, ICD, and AST activities showed a biphasic pattern, first increasing and then decreasing; (e) ALT, LDH, HBD, CK, and ALP activities decreased; and (f) GGT activity remained unchanged. The differences in the profiles of the enzyme activities suggest their independent regulation in experimental NS induced by PAN.

The present study examined the preventive effects of green tea extract on D-galactosamine (GalN)-induced hepatic injury in rats, an animal model of viral hepatitis. A single i.p.-injection of GalN (700 mg/kg) to male Wistar rats caused fulminant hepatitis by 48 hr as assessed by marked increases in the serum aspartate aminotransferase (GOT), alanine aminotransferase (GPT) and alkaline phosphatase (ALP) activities; decreases in the serum protein and cholesterol levels and the amount of liver microsome P-450; and marked changes in organ weights. The lecithin: cholesterol acyltransferase (LCAT) activity markedly increased at 8 hr and markedly decreased at 24 hr after the GalN injection. In the experiment, animals were orally administered green tea extract at doses of 50, 100 or 200 mg/kg five times each before and after the GalN injection. Treatment with green tea extract significantly prevented the increases in the GOT, GPT and ALP activities in a dose-related manner. It also significantly prevented the decreases in serum albumin and total cholesterol, although not in a dose-related manner. A tendency to prevent the increase in LCAT activity and the decrease in liver microsome P-450 was also noted. Little effect was found on the other abnormal changes in the serum lipids and proteins and the organ weights. These results suggest that green tea may have an ameliorating effect on hepatic dysfunction.

Monoclonal gammopathies can either be benign or more commonly malignant. The commonest disease associated with it is multiple myeloma. Over the seven-year period 1984-1990, two hundred and thirty-four monoclonal gammopathies were seen at the University Hospital, Jamaica. Multiple myeloma was diagnosed in one hundred and fifty-six cases (84 males and 72 females). The diagnoses of most of the others were not known as the samples came from other institutions. Of the patients with myeloma, the most common immunoglobulin type was IgG followed by IgA and then pure light chain disease. Only in about half of the cases where urine was analysed was Bence-Jones protein found. The majority of the cases had abnormal total serum protein, albumin and total globulin concentrations. Most of the cases also were in renal failure. Hypercalcaemia, hyperphosphataemia, elevated alkaline phosphatase, gammaglutamyl transferase and aspartate aminotransferase occurred in about one-third of them. These results were not much different from those reported in other countries.

In the mouse experimental model the effect of two different methods of myeloablation-immunosuppression treatment administered as preparation for bone marrow transplantation was studied, also the effect of animal's age on the values of the essential biochemical parameters in the serum and on the body weight of the animals was assessed. The recipients were prepared for the transplantation with total-body irradiation and administration of cyclophosphamide (radio-chemotherapy) or administration of busulphan with cyclophosphamide (combined chemotherapy). Transplantation was done in animals aged 2.5 and 12 months. In all studied animals serum protein and calcium levels were decreased after the transplantation and the uric acid level was transiently raised. In the older mice a short lasting increase in the serum levels of bilirubin, alkaline phosphatase, AST and ALT was noted. However, no changes were found in the results biochemical investigations which could have been related to the method of myeloablation and immunosuppression, apart from slight hypercholesterolaemia which developed about 30 days after the operation in mice prepared by radio-chemotherapy. However, after a year lower body weight was observed in young mice prepared for the procedure with radiation exposure and cyclophosphamide, as compared to those receiving combined chemotherapy. Clinical aspects of these disturbances are discussed.

Changes in the blood serum protein and mineral composition, trypsin inhibitor content, alanine amino-transferase, aspartate aminotransferase, alpha-glutamyl transpeptidase, creatine kinase, choline esterase activities, blood plasma trace element levels were examined in 112 patients with pyoinflammatory involvement of the soft tissues of the face and neck. The study was revealed reduced blood serum albumin concentration, elevated trypsin inhibitor levels and alpha-glutamyl transpeptidase and creatine kinase activities, decreased content of Mg and Zn and, in some patients, of choline esterase activity. Biochemical parameters gradually normalize, as the patients recover, their normalization depending on the therapeutic methods and detoxication treatment.
