Antemortem and postmortem sera from 60 dogs were evaluated for lipase, amylase, alkaline phosphatase, gamma-glutamyltransferase, and alanine aminotransferase (AAT); cerebrospinal fluid was examined for AAT and alkaline phosphatase. The postmortem intervals were 3, 6, 12, 24, and 48 h at temperatures of 4, 20, and 37 degrees C. Amylase levels remained stable at 4 and 20 degrees C and may be beneficial for diagnosing pancreatitis. Lipase levels may be useful as an adjunct to amylase values. Serum alkaline phosphatase values increased with postmortem interval; values were higher at 37 degrees C than at 4 degrees C. Other enzymes were of little value for diagnosis.

In a model developed to study acute pancreatitis in the dog, the disease process was comparable with the spontaneously occurring disease. Infusion of oleic acid into the accessory pancreatic duct induced, grossly and microscopically, acute hemorrhagic pancreatitis with pancreatic atrophy, fibrosis, fat necrosis, and edema. Clinical changes included persistent fever and tachycardia in all dogs and abdominal pain, vomiting, and diarrhea in most. Serum amylase and lipase activities increased markedly as did activities of alkaline phosphatase, aspartate aminotransferase, and alanine aminotransferase. Hematologic alterations included hemoconcentration (despite intensive fluid therapy) and leukocytosis due primarily to neutrophilia and monocytosis. Neither corticosteroid nor anticholinergic therapy begun 24 to 32 hours after oleic acid infusion altered the course of the disease. Dogs survived 8 days and appeared clinically normal when the study was terminated.

Activities of 12 enzymes (amylase, lipase, cholinesterase, nonspecific carboxyl esterase, lactate dehydrogenase (LDH), alkaline phosphatase, glutamate-oxalacetate transaminase (GOT), glutamate-pyruvate transaminase (GPT), gamma-glutamyl transferase (gamma-GT), leucine aminopeptidase (LAP), malate dehydrogenase (MDH) and peroxidase) were determined in the perienteric fluid and homogenate of Ascaris suum. With the exception of amylase, all activities were higher in the homogenate than in the perienteric fluid. The enzyme activities in the perienteric fluid were then compared with those in the human serum. Comparable activities were demonstrated for LDH, LAP, lipase and alkaline phosphatase, markedly higher activities in perienteric fluid were demonstrated for MDH, GOT, GPT and amylase, and much lower for cholinesterase. No gamma-GT activity was detected in the perienteric fluid.

Prostaglandin E2 (PGE2)-like activity was measured in osteonecrotic femoral heads caused by high doses of methyl prednisolone acetate in rabbits. Serum levels of cholesterol, total lipids, free fatty acids, alkaline phosphatase, SGOT and lipase were also determined. There were increases in local tissue PGE2-like activity, serum cholesterol, total lipid and free fatty acid levels in rabbits with steroid-induced osteonecrosis as compared to the controls. The rabbits given aprotinin together with the steroid showed significant decreases in serum cholesterol and lipid levels coupled with a marked increase in the local PGE2-like activity. Aprotinin prevented osteonecrosis induced by steroids. The results are discussed in the light of the relevant literature.

The effect of sodium dodecyl sulfate on the activity of highly purified or crystalline enzymes has been studied. The enzymes were: lactate dehydrogenase (LDH), malate dehydrogenase (MDH). isocitrate dehydrogenase (ICDH), glucose-6-phosphate dehydrogenase (G6P-DH), lipase, alkaline phosphatase. Sodium dodecyl sulfate, always under the critical micellar concentration, shows a selective inhibitory effect. A kinetic analysis of the inhibitory action on LDH, MDH, ICDH and G6P-DH was also carried out.

Porcine rotaviral infectivity for continuous porcine kidney (PK-15) cells was enhanced by incorporation of pancreatic endopeptidases into the cell culture maintenance medium. Marked enhancement of infectivity was induced by trypsin, whereas elestase and alpha-chymotrypsin enhanced infectivity to a lesser extent. Bacterial protease also induced some enhancement of porcine rotaviral infectivity. A synergistic enhancement of porcine rotaviral infectivity was noticed with trypsin and alpha-chymotrypsin combined. Porcine rotaviral infectivity was not affected by incorporation of alpha-amylase, alkaline phosphatase, beta-galactosidase, carboxypeptidase-A, deoxyribonuclease, enterokinase, lipase, or ribonuclease into the maintenance medium.

The effect of 1-butanesulfonic acid sodium salt and sodium dodecyl sulfate on the activity of highly purified and crystalline enzymes with marked differences in structure and function has been studied. The enzymes were: alcohol dehydrogenase; lactate dehydrogenase; malate dehydrogenase; isocitrate dehydrogenase; glucose-6-phosphate dehydrogenase; lipase; alkaline phosphatase. While 1-butanesulfonic acid sodium salt, at the studied concentrations, resulted generally inactive, sodium dedecyl sulfate showed a selective inhibitory effect, always under the critical micellar concentration. A kinetic analysis of the inhibitory action was also carried out.

Although zinc in traces is essential for the growth and well being of the animal, however a long-term treatment has been found equally toxic to the liver and kidney. Present report describes its effects on few key enzymes viz. alkaline phosphatase, acid phosphatase, 5-nucleotidase, lipase, glucose-6-phosphatase, and cholinesterase in the liver of rat, Rattus rattus albino. Histochemical observations have provided visual evidences on Zn-induced dysenzymia. The results have further been interpreted in terms of its effects on cellular organelle, levels of enzyme protein and microenvironment of the hepatic parenchyma.

Some hydrolases are localized cytochemically in the pollen and pollen tubes of Amaryllis vittata Ait. The function of different enzymes is discussed in relation to pollen tubes morphogenesis. Activity of most of the enzymes was confined to colpus region, pollen wall and general cytoplasm of pollen and pollen tube. The activity of hydrolytic enzymes like acid monophosphoesterase and lipase and was nil in the exine of both germinated and ungerminated pollen, whereas intense reaction for esterase was observed in exine. Enzyme activity increased after germination which suggest the hydrolysis of stored metabolites and synthesis of proteins and other metabolites for the active growth of pollen tube. Intense reaction for enzymes like alkaline phosphomonoesterase, ATP-ase, 5-nucleotidase etc. at the tip region of pollen tube suggest their role in physiological processes associated with exchange of materials through intercellular transport during tube wall polysaccharide biogenesis.

An attempt has been made to observe the effects of chromium on a few enzymes, viz. alkaline phosphatase, acid phosphatase, glucose-6-phosphatase and lipase, in the kidney of the rat (Rattus rattus albino) by means of histochemical and biochemical criteria. Administered as potassium chromate in the diet, it was found to inhibit the activity of these renal enzymes; moreover, characteristic differences were observed in their anatomic localization. The possible effects of chromium on the level of enzyme protein and the state of the cellular organelles, together with modifications of biochemical processes such as phosphorylation, adenylation and oxidative phosphorylation, are discussed.
