We have selected for this study a well-defined group of patients with moderately advanced but compensated alcoholic cirrhosis. They were well-nourished and had no ascites, varices, azotemia, or encephalopathy. Liver biopsy showed little or no necrosis and inflammation despite wide-spread fibrosis. Serum bilirubin, transaminase, alkaline phosphatase, albumin and globulins were essentially normal. Biochemical evidence for liver disease was restricted to modest elevation of BSP retention, gamma GTP, serum bile acid concentrations, and urinary bile acid excretion. Except for changes in the interrelationships among the three biliary lipids, they were generally spared the abnormalities of sterol metabolism described in other patients with more advanced, more active liver disease. Thus, striking abnormalities in the metabolism of cholesterol and bile acids probably require severe reductions in functioning hepatocellular mass, major portal-systemic shunting, high disease activity, or all three to become manifest.

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.

The use of intestinal segments in the urinary tract can cause metabolic changes that depend on the intestinal segment utilized. The severity of these changes basically depends on the area of the intestinal mucosa in contact with urine, the duration of exposure to urine and renal function. The length of time the intestinal mucosa is in contact with urine largely depends on the surgical technique employed. It is longer for the reservoirs, intestinal neobladders and ureterosigmoidostomies than for the intestinal conduits with cutaneous urinary diversion and therefore carry a higher incidence of metabolic changes. Jejunal urinary diversion causes metabolic acidosis with hypochloremia, hyponatremia, hyperpotassemia, azotemia and dehydration in at least 50% of the cases. Ileal and colonic urinary diversion can cause metabolic acidosis, although the incidence is significantly less. Acidosis presents with hyperchloremia, hyperammonemia, hypersulfatemia, increased osmolality and uremia with normal creatininemia and a tendency to develop hypocalcemia, hypophosphoremia and hypomagnesemia. Recent studies performed in our service show that acidosis is basically due to the secretion of sodium bicarbonate by the intestinal segment used in the urinary tract, which causes water-salt depletion that is compensated by secondary hyperaldosteronism. Mild chronic acidosis is neutralized via the respiratory system and by the bone buffers, which leads to bone remodelling manifested by the significant increase of serum alkaline phosphatase levels and increased calciuria. These calcium phosphate changes, although statistically significant, do not appear to be important since they were not accompanied by changes of serum PTH levels, 25 and 1-25-cholecalciferol. Nicotinic acid as inhibitor of cyclic AMP synthesis failed to correct metabolic acidosis in the patients with transileal diversion.

We determined approximately 15,000 laboratory values in 236 individuals between the ages of 60 and 90 y, 22 individuals between 90 and 99 y, and 69 individuals greater than or equal to 100 y, and compared these with values in young adults. We tested 47 different analytes in the 60-90-y group and 93 analytes in the greater than or equal to 90-y group. Na, K, Cl, and CO2 values were either identical or showed minimal change with age; pH decreased slightly. Differences in Ca values were only minor, but ionized Ca increased slightly. Phosphate decreased in men, but changed only minimally in women; parathyroid hormone increased with age. Increases with age were also observed for glucose, insulin, and C-peptide. Among the enzymes, alkaline phosphatase increased in women, but in men only greater than 90 y; gamma-glutamyltransferase increased in both sexes. Creatine kinase (CK) decreased slightly in individuals greater than 70 y and markedly in those greater than 90 y of age, whereas CK-MB decreased markedly greater than 70 y, reaching the detection limit in individuals greater than 90 y. Lactate dehydrogenase isoenzyme 5 decreased slightly with age. Urea nitrogen increased gradually with age, but creatinine increased only in individuals greater than or equal to 90 y. The increase in urea is not paralleled by a loss of protein in urine, suggesting that the possible cause of azotemia may not always be renal pathology. Urate increased in women but not in men. Liver function, as measured by total bilirubin and liver enzymes, was exceedingly well maintained. Concentrations of most proteins show little change, except for slight decreases in prealbumin, albumin, and transferrin, proteins used as an index of nutritional status. IgA values increased, IgG ranges were wider, IgM and IgD decreased, and the range for IgE was narrower than in young adults. Cholesterol, high-density lipoprotein cholesterol, and triglyceride values increased with age, but decreased in individuals greater than or equal to 90 y. Among the trace elements, magnesium changed little, zinc and lead decreased, and copper values increased with age. Total triiodothyronine and thyroxine decreased, with concomitant increases in thyroid-stimulating hormone. More individuals had increased microsomal antibodies and thyroglobulin titers in the aging population than in the young. In men, the free, percent free, bioactive, and total testosterone values decreased, but luteinizing hormone (LH) and follicle-stimulating hormone (FSH) values increased. In women, estrone and estradiol values decreased, with concomitant increases in LH and FSH. Androstenedione and progesterone decreased in both sexes.(ABSTRACT TRUNCATED AT 400 WORDS)

20 patients, aged between 31 and 71, have been treated. All were hospitalized because of acute or chronic broncho-pneumopathy and have been administered 4-carbomethoxythiazolidine at a dosage of 300 mg/d. in association with the common antibiotic or chemiotherapic treatments. Every day all symptoms have been registered (asthenia, cephalea, sibiluses, rhoncuses, rales, inspiratory and expiratory dyspnea). Before and after the treatment some respiratory functioning tests have been performed, including the VEMS and VEMS/CV determination. A further study on the distribution of the inhaled air has been carried out, as well as on the ventilation/perfusion ratio by means of He and CO2 curves. At the beginning and at the end of the TMC treatment some hematiobiologic tests have been carried out, including: haemochromo with leukocytic formula, blood platelets counting, VES, glycemia, azotemia, transaminase, alkaline phosphatase, total bilirubinaemia, prothrombinic activity and determination of urine's specific weight. The pulmonary symptomatology (cough, sibiluses, rhoncuses, rates, inspiratory and expiratory dyspnea), was markedly reduced. Even if, as for the preliminary character of the experiment, we can state that 4-carbomethoxythiazolidine is a drug with an outstanding level of tolerance.

Acute zinc toxicosis from the ingestion of pennies was diagnosed in a dog with Heinz body hemolytic anemia (PCV = 14%), leukocytosis (51,000 cells/ml) with a left shift (3,060 band neutrophils; 37,740 segmented neutrophils) and monocytosis (4,080 cells/ml), azotemia (BUN = 60 mg/dl), bilirubinemia (total bilirubin = 5.3 mg/dl), hypokalemia (3.0 mEq/L), high serum alkaline phosphatase activity (691 U/L), high total plasma solids (8.1 g/dl), hemoglobinuria, and proteinuria. Despite aggressive medical treatment, renal failure ensued, and the dog died of cardiac arrest. The clinical signs, clinical course, and laboratory findings in this dog were similar to what has been reported in other cases of acute zinc toxicosis in dogs, with the exception of a history of generalized seizures and the findings of Heinz bodies. Although a causative relationship between plasma zinc values and Heinz body formation cannot be proven, their association suggests that oxidative damage to erythrocyte hemoglobin and cell membrane proteins may be involved in the pathogenesis of zinc-induced hemolysis.

The systemic administration of interleukin-2 (IL-2) can lead to significant antitumor responses in some patients with metastatic cancer in whom standard therapy has failed. A limitation of this immunotherapy is the toxicity associated with IL-2 infusion. To assess toxicity, we determined aspartate aminotransferase (AST; EC 2.6.1.1), alanine aminotransferase (ALT; EC 2.6.1.2), gamma-glutamyltransferase (GGT; EC 2.3.2.2), lactate dehydrogenase (LD; EC 1.1.1.27), alkaline phosphatase (ALP; EC 3.1.3.1), creatine kinase (CK; EC 2.7.3.2), total bilirubin (TBI), direct bilirubin (DBI), creatinine, urea nitrogen, and C-reactive protein in serum from 21 patients before and during five consecutive days of IL-2 treatment. Ten patients were followed for an additional five days after the end of IL-2 therapy. The IL-2 infusion caused liver toxicity and prerenal azotemia, as evidenced by significant increases (P less than 0.05) of all analytes except CK by day 1. There was a progressive increase in the results (except CK) for these tests until IL-2 treatment was stopped. Seven tests related to liver function (AST, ALT, GGT, LD, ALP, DBI, and TBI) showed increases, but the test results indicated significant improvement and moved toward the baseline value five days after the end of IL-2 therapy. Concentrations of creatinine and urea nitrogen in serum were normal three days after the cessation of IL-2 therapy.

An open, randomized, controlled study including 57 patients with acute cerebral infarct was performed. All the patients, followed and controlled by the same examiner, received, in the first ten days, 24 mg/die i.v. of dexamethasone. 28 patients were also treated with mesoglycan (150 mg/die i.m. for five days and 144 mg/die per os for a further twenty-five days). The differences between the basal and final scores in the mesoglycan group and in the controls were not statistically significant as analysed by the Mann-Whitney U test. The mesoglycan influenced only slightly the laboratory values (PT, PTT, alkaline phosphatase, GOT, GPT, cholesterol and triglycerides, fibrinogen, blood glucose, azotemia and creatinine) performed before the beginning of the treatment, as their changes after thirty days of therapy were in the normal range. The mesoglycan was very well tolerated and no side-effects were observed during the treatment.

The medical records of 14 hyperthyroid cats with thyroid carcinoma were analyzed retrospectively regarding historical, physical, laboratory, and thyroid scintiscan findings, treatment, and treatment outcome. Breed predilection was not detected, and older castrated male cats were most commonly affected. The most common clinical signs detected by owners were weight loss, polydipsia, polyuria, polyphagia, hyperactivity, and anorexia. Physical examination findings included tachycardia, palpable cervical mass, hyperactivity, cardiac murmur, and abnormal coat. Common abnormal laboratory findings were high serum thyroxine and triiodo-thyronine concentrations and high serum alanine transaminase, alkaline phosphatase, and aspartate transaminase activities. Azotemia, hyperphosphatemia, and hyperglycemia were noticed less frequently. The most common thyroid scintiscan findings were multiple nodular areas of high radionuclide uptake in the cervical region, thoracic inlet, and cranial mediastinum. The most common morphologic diagnosis was mixed compact and follicular carcinoma, with follicular and papillary carcinomas being less common. Most cats responded well to treatment of the thyroid tumor, with rapid resolution of the historical and physical examination findings. The most common necropsy findings were local tumor invasion, regional lymph node metastases, cardiomyopathy, and interstitial nephritis.

Chronic mercuric chloride intoxication in an aged horse given 0.8 mg Hg/kg/day for 14 weeks was manifest by signs of progressive respiratory difficulty and renal disease. The effects were not self-limiting after mercury was withdrawn, and the animal was destroyed six weeks later. Renal function changes included heavy glycosuria, modest proteinuria, phosphaturia, reduced urine osmolality, gradually increasing urine production, reduced glomerular filtration rate, and terminally, azotemia. The condition bore similarities to the Fanconi syndrome in man. Urinary gamma-glutamyl transpeptidase, alkaline phosphatase and amino-aspartate transferase activities were inconsistent indicators of tubular damage in random samples at this dose rate. The pathologic response was characterized by extensive granulomatous infiltration throughout the lungs, in particular, and to a lesser extent in the kidneys, liver and bone marrow. The renal changes included this marked interstitial reaction and proximal tubular degeneration. Mercury levels were negligible in the lungs and highest in the renal cortex. The granulomatous reaction was not encountered in previous mercury toxicity studies in horses and may indicate an individual sensitivity to the agent.
