The serum concentration of bilirubin and the activities of aspartate aminotransferase (ASAT, GOT), alanine aminotransferase (ALAT, GPT), gamma-glutamyltransferase (GT), total amylase and pancreatic isoamylase have been determined in serum of 182 male chronic alcoholics. Twelve per cent had abnormally high levels of bilirubin, 73% increased activity of S-ASAT, 50% increased S-ALAT, and 69% increased S-GT. The highest values were often found after 5-20 years of well documented alcoholism. Some patients with alcoholism of more than 20 years' duration displayed a slight tendency towards normalization of the activities. For all parameters the scatter around the mean was greater in the patients than in the controls. Patients who had had attacks of delirium showed slightly higher S-ASAT and S-ALAT than other alcoholics. Determination of S-ALAT and S-bilirubin did not add to the cases with abnormal laboratory tests demonstrated by the combination of S-ASAT and S-GT. In 14 patients the above mentioned parameters were within normal limits, even though severe alcoholism had lasted for many years. Isoamylase determination disclosed 20% to have decreased activity of pancreatic isoamylases in serum, whereas only 6% had low total serum amylase activity.

1. The activities of lysozyme, acid and alkaline phosphatases, beta-glucuronidase, amylase, lipase, glutamate-oxalacetate transaminase, and glutamate-pyruvate transaminase in the whole hemolymph and 4000 g pellets and supernatants of Mya arenaria were determined. 2. All of these enzymes, except for amylase, occurred in whole hemolymph as well as in the 4000 g pellet and supernatant. 3. Based on earlier observations, these enzymes are believed to be of cellular origin within hemolymph cells. 4. In the case of amylase, it only occurred in the whole hemolymph and/or serum and is believed to have originated from the crystalline style.

Autotransplantation of pancreatic microfragments into the liver or the spleen of totally pancreatectomized dogs is described. Both modes of transplantation resulted in restoration of normal fasting blood glucose levels. A delayed response to high glucose loads was however observed in both groups. Serum amylase levels indicated a rapid decline of exocrine activity. On the basis of postoperative levels of GOT and GPT in the serum of the dogs with intraportal transplants, permanent proteolytic or ischemic damage to the liver appeared unlikely.

Two patients with anorexia nervosa with evidence of pancreas and liver injury are reported. Both showed evidence of organ dysfunction in the presence of cachexia. Serum amylase, ASAT (GOT), and ALAT (GPT) became normal parallel with body weight. On the basis of reports on the effects of malnutrition on pancreas and liver function, it is suggested that nutritional pancreas and liver dysfunction might represent hitherto unrecognized complications of anorexia nervosa.

In rats, shortly after ligation of superior mesenteric artery serum enzyme activities are found significantly altered. Those changes concern aspartate aminotransferase (GOT), alanine aminotransferase (GPT), lipase, alpha amylase, and isocitrate dehydrogenase as well as glutamate dehydrogenase. The causes are discussed. The authors emphasize that the assessment of serum enzymes possibly gives some help in diagnosing acute intestinal ischemias in early stages.

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.

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.

Serum GOT, GPT, LDH, CHE, MDH, SDH, PK, GLDM, LAP and amylase levels and serum ammonia were determined in 49 major burn cases with 2nd and 3rd degree lesions covering 25% to 80% of the body surface. GOT, GPT, LDH, CHE and gamma-GT have above normal in all cases. Limited and inconsistent movements were noted for the remaining enzymes. Blood ammonia was constantly increased and it is felt that the enzyme picture may be of considerable prognostic value in major burn cases.

The development of toxicity to 4'-demethylepipodophyllotoxin-9-(4,6,-O-thenylidene-beta-glucopyranoside) an epipodophyllotoxin with oncolytic activity, was characterized in mice treated three times at 3-day intervals with 10 mg of drug i.p. per kg of body weight. Changes in organ function and general metabolism were determined by measuring 18 constituents of blood for up to 10 weeks after drug administration. The results indicate three distinct phases of toxicity to 4'-demethylepipodophyllotoxin 9-(4,6-O-2-thenylidene-beta-glucopyranoside). Acute toxicity developed within the first 10 days and was expressed by a depressed hematocrit and elevated plasma levels of glutamate-pyruvate transaminase, glutamate-oxaloacetate transaminase, lactic dehydrogenase, amylase, lipase, and uric acid. By 4 weeks, levels ahd returned to normal. The acute phase was followed by a chronic phase, which was characterized by progressive decreases in plasma levels of glucose, cholesterol, albumin, and total protein. Finally, about 7 weeks after treatment, a terminal phase indicated by correlated increases in glutamate-pyruvate transaminase, glutamate-oxaloacetate transaminase, lactic dehydrogenase, and blood urea nitrogen became apparent. Plasma levels of creatine phosphokinase, calcium, inorganic phosphate, total bilirubin, ketones, and alkaline phosphatase did not change. Although the pancreas liver and marrow were all affected during acute toxicity, boserved changes in blood components during the chronic and terminal phases correlate best with continued hepatotoxicity. The present evidence on delayed toxicity to 4'-demethylepipodophyllotoxin 9-(4,6-o-2-thenylidene-beta-D-glucopyranoside) is most compatible with irreversible hepatotoxocity which leads to metabolic deficiencies and terminates in death of mice.

Nonvaccinated pigs were infected with a pathogenic virus of swine fever in order to follow up the changes with some enzymes in their blood serum. It was found that there is a dependable rise in the values of the blood serum GOT (2.6.1. 1.) - From about 38 to approximately 108 mU per cu. cm; GPT (2. 6; 1.2.;-From about 12 up to 66 mU/cu. cm; LAP (3. 4. 1. 1)-from about 13 to 27 mU/cu. cm; and ALD (4. 1; 2. 7.) - from about 6 up to 19 mU/cu. cm. These changes were noticed as early as the 48th hour of infection, prior to the manifestation of the clinical symptoms of swine fever. They remained stable up to the end of the infection process. The activity of LDH (1. 1. 2. 7.) and amylase (3. 2. 1.1 .) was said to rise (not dependable statistically), and that of cholinesterase (3. 1 1. 8) - to drop gradually with the development of the infection process. The two phosphomonoesterases (3. 1. 3. 1 and 3. 1. 3. 2.) showed no essential changes. The changes taking place in the activity of these enzymes did not depend on the extent of the hemorrhagic diathesis characteristic of swine fever. So, this test, which has been unknown so far, is referred to as a characteristic paraclinical symptom of swine fever.
