Medical records of 11 cats with lymphoma involving large granular lymphocytes were reviewed. All 9 cats tested were FeLV-negative. Ten cats had a history of anorexia, lethargy, vomiting, or diarrhea, and had lymphoma involving abdominal viscera. The most common site of tumor in these cats was the jejunum. One cat had cutaneous masses caused by dermal and epidermal infiltration with neoplastic large granular lymphocytes. The most common hematologic abnormality was leukocytosis, characterized by neutrophilia with a left shift (7 cats); 2 cats had a left shift without neutrophilia. None of the cats had lymphocytosis, but immature large granular lymphocytes were found in the blood of 4 cats. The most common serum biochemical abnormalities were hypoalbuminemia (10 cats), hypocalcemia (10 cats), hypoproteinemia (9 cats), high aspartate transaminase activity (9 cats), and hyperbilirubinemia (8 cats). Large granular lymphocytes were characterized by abundant cytoplasm containing distinct azurophilic granules that varied in size and number. The most common cytochemical staining pattern included detection of alpha-naphthyl butyrate esterase, acid phosphatase, and beta-glucuronidase activities. On examination of histologic sections, granules stained weakly eosinophilic with Giemsa and moderately with periodic acid-Schiff reaction. Ultrastructurally, the granules appeared membrane bound and contained an electron-dense matrix in 4 cats.

The alterations of haematological parameters in albino rats were studied after oral administration of an aqueous extract of silken styles of corn (Zea maize Linn.) at 50, 100 and 150 mg kg-1 daily for 21 days. The following haematological values were significantly reduced on the 7th and 21st day following extract administration: haemoglobin (Hb), red blood corpuscles (RBC), clotting time (CT), mean corpuscular volume (MCV), haematocrit (Ht), serum glucose, blood urea nitrogen (BUN), cholesterol, aspartate transaminase (AST), alanine transaminase (ALT), calcium, total protein, total albumin and total acid phosphatase; and white blood corpuscles (WBC), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), alkaline phosphatase and creatinine increased. The remaining parameters were not significantly affected, except body weight parameters at the two highest doses. The results emphasize that the biochemical changes caused through aqueous extract of silken styles of corn (Zea maize Linn.) are not significantly toxic at low and medium doses (50 and 100 mg kg-1).

Effect of A. indica leaf extract on serum enzyme levels (glutamate oxaloacetate transaminase, glutamate pyruvate transaminase, acid phosphatase and alkaline phosphatase) elevated by paracetamol in rats was studied with a view to observe any possible hepatoprotective effect of this plant. It was interesting to observe that serum enzyme levels were much elevated in paracetamol induced animals than in those receiving a combination of paracetamol and lead extract. It is stipulated that the extract treated group was protected from hepatic cell damage caused by paracetamol induction. The findings were further confirmed by histopathological study of liver.

The activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), acid phosphatase (ACP), lactate dehydrogenase (LDH) and isocitric dehydrogenase (ICD) in the serum of 60 healthy dromedary camels of either sex and different ages (one to 25 years) were determined. The results were analysed with respect to time of year (December-January and May-June), sex and age groups (below four years; four to 10 years; and over 10 years). The overall mean activities of AST, ALT, ALP, ACP, LDH and ICD were 36.1 +/- 0.35, 4.65 +/- 0.35, 27.21 +/- 0.43, 7.18 +/- 0.21, 479.0 +/- 7.33 and 7.74 +/- 0.17 iu litre-1, respectively. Activities of AST, ALT, ALP and ACP were significantly higher during extremely hot conditions (May-June) than in extreme cold (December-January) while the activity of LDH was higher in extremely cold conditions. Analysis of data based on sex revealed that AST, ALT and ALP activities in the serum of male animals were significantly higher than in female animals. The activities of all the enzymes were highest in animals under four years and then gradually decreased with age being lowest in the animals over 10 years.

Significant increase in the activity of liver succinate dehydrogenase (SDH) was observed in male Wistar rats, fed Aroclor 1260 (PCB; polychlorinated biphenyl) at 50 and 100 ppm level for 120 days. Lactate dehydrogenase (LDH) activity increased in 50 ppm PCB fed animals and decreased in 100 ppm PCB fed rats. On the other hand, enzymes like alanine and aspartate aminotransferase, alkaline and acid phosphatase showed remarkable decrease in activity in PCB fed animals. Slab gel electrophoresis of LDH isozymes showed remarkable increase in LDH2 and LDH3 and to some extent increase in LDH1 isozymes of livers of 50 ppm PCB fed animals but not in 100 ppm PCB fed groups as compared to controls. In both the PCB fed groups, liver showed centrilobular hypertrophy, hepatocellular damage, hyperplasia, karyolysis and karyorrhexis.

The activity of lactate dehydrogenase (LDH), indophenol oxidase, aspartate aminotransferase (AsAT), alkaline phosphatase, acid phosphatase and aldolase at different stages of rat development was measured. We have also determined changes in the activity of these enzymes resulting from transplantation of embryonic nerve tissue (ENT) into the brain of adult animals. During development from the embryo to the adult animal, LDH and AsAT activities increased, while alkaline phosphatase activity diminished. After ENT transplantation, the most prominent changes were in the alkaline phosphatase activity whereas the activity of LDH, AsAT and acid phosphatase remained unchanged and similar to that in the brain cortex of intact adult animals. Changes in the enzyme activity resulting from ENT transplantation changed in a manner characteristic of the transplant. Local brain damage did not change the activity of the studied enzymes fifty days after surgery.

Dichlorvos was applied as spray at 1 and 2% concentrations daily for a period of 28 and 21 consecutive days, respectively to buffalo calves. Animals sprayed with 1% dichlorvos displayed mild to moderate clinical signs of toxicosis during the 4th week of exposure. The higher concentration (2%) produced clinical signs of poisoning after 12-16 applications, and was lethal to one of three animals. Daily spraying of dichlorvos at both concentrations inactivated erythrocyte cholinesterase (ChE) (15-21%), plasma ChE (17-20%) and serum carboxylesterase (5-10%) within 3 days. The extent of inhibition of esterases was increased with repeated treatment and maximal inhibition of erythrocyte ChE (80-89%), plasma ChE (81-91%) and serum carboxylesterase (33-54%) with 1 and 2% concentrations was observed on the 28th and 21st day after start of application, respectively. In surviving animals, blood esterases remained inactivated to the extent of 14-65% on the 14th day after the termination of treatment. Dichlorvos at both concentrations significantly (P less than 0.01) elevated the serum levels of aspartate aminotransferase, alanine aminotransferase, acid phosphatase and alkaline phosphatase. The activities of these enzymes in surviving animals recovered to control values within 14 days after the final application of dichlorvos.

The haematological and hepatotoxic effects were studied after oral administration of Isoprocarb at 75, 112.5 and 150 mg kg-1 daily for 21 days in male and female chicken Gallus gallus domesticus (White Leghorns). The toxic effects as observed 10 or 21 days after medication include a statistically significant reduction in haemoglobin (Hb) content, haematocrit (Ht), protein and serum glutamate pyruvate transaminase (SGPT), and an increase in glucose, serum glutamate oxaloacetate transaminase (SGOT) and serum acid phosphatase (SAP) activities of male and female chicken. The changes in other haematological parameters were generally insignificant, except for one or two doses in RBC, WBC, mean corpuscular haemoglobin concentration (MCHC) and chloride. A significant inhibition of RBC acetylcholinesterase was noticed after 21 days of dosing only at the high dose (150 mg kg-1) in hens. The decrease in food intake and body weights of males and females indicated the overt signs of toxicity. In addition to haematological alterations, the results suggest both hepatotoxic and stress effects and pinpoint that these early biochemical changes induced by Isoprocarb may be predictive of pesticide toxicity.

Administration of carbon tetrachloride to normal rats increased activities of hepatic 5(1)-nucleotidase, acid phosphatase, acid ribonuclease while the activities of succinate dehydrogenase, glucose 6-phosphatase, superoxide dismutase and cytochrome P450 were decreased. Levels of lipid peroxides, total lipids and cholesterol of liver were also increased. The activities of serum glutamate oxaloacetate transaminase, glutamate pyruvate transaminase and alkaline phosphatase were increased. Other serum parameters showing changes after carbon tetrachloride were: bilirubin, proteins, cholesterol, triglycerides and lipoprotein-X. Picroliv (from the plant Picrorhiza kurroa) in doses of 6 and 12 mg/kg provided a significant protection against most of the biochemical alterations produced by carbon tetrachloride. The degree of protection afforded by picroliv, when administered simultaneously or as a pretreatment was almost equal.

Dietary hexachlorocyclohexane (HCH) and gamma-isomer of HCH produced significant increase in liver weights of mice. Elevated levels of alanine and aspartate aminotransferases and of alkaline phosphatase in the blood of these animals suggested hepatotoxicity. Hepatic soluble enzymes--aspartate aminotransferase and lactate dehydrogenase--were markedly lowered. Among the hepatic lysosomal enzymes, acid phosphatase and acid cathepsin were increased in the experimental animals. Hepatic glucose-6-phosphatase was lowered by HCH while aldolase activity was increased. Hydrolytic enzymes in small intestine, viz., disaccharidases, lipase, amylase, dipeptidase and phosphatases, were also affected by dietary HCH and gamma-HCH. The results suggested cellular toxicity in hepatocytes of HCH and gamma-HCH fed animals, and also interference in gastrointestinal absorption.
