The aim of this study was to analyze the alterations in homeostasis induced by Junin virus during acute and persistent infection of C. musculinus. Virus presence in brain, hematological response and glycemia levels were evaluated. Newborn C. musculinus inoculated with 4000 DL50 of Junin virus, strain XJCl3 by intraperitoneal route developed a typical acute disease, with 50-70% mortality. Virus was isolated from brain starting day 6 post-infection (Fig. 1) and the peak titer (10(8) DL50/ml) was reached at 12 days post-infection. Neutralizing anti-Junin virus antibodies were detected from day 11 post-infection and all chronically infected animals developed persistent levels of neutralizing antibodies. In the acute stage of infection, 40% of the animals developed lymphopenia and neutrophilia (Fig. 2) while a slight variation was observed in the monocyte population. An important hypoglycemia was also seen in the acute infection (mean = 3.52 mmol/l) in comparison with control values (mean = 6.21 mmol/l), p less than 0.01 (Fig. 3). By contrast during the chronic stage of infection, neither hematological parameters (Table 2) varied between infected and control animals.

Amanita phalloides mushroom poisoning is an increasingly common and potentially lethal problem for which liver transplantation offers definitive therapy in selected patients. When significant liver dysfunction appears, early transfer to a liver transplant center is important to identify appropriate candidates and to begin the search for a donor organ. The clinical course of five severely poisoned patients, four of whom underwent liver transplantation, is reviewed. Indications for transplantation included primarily a markedly prolonged prothrombin time that was only partially correctable and a constellation of findings including metabolic acidosis, hypoglycemia, hypofibrinogenemia, and increased serum ammonia, following a marked elevation in serum aminotransferase levels. Unlike viral fulminant hepatic failure, grade III or IV hepatic encephalopathy, marked elevation of the serum bilirubin level, and azotemia were not indications for transplantation. Resected livers demonstrated hepatocyte viability of 0% to 30%. Manifestations of Amanita poisoning complicating preoperative and/or postoperative care included severe diarrhea, gastrointestinal hemorrhage, hypophosphatemia, bowel edema, and marrow suppression with lymphopenia, thrombocytopenia, and neutropenia. All five patients are well 1 year later. This largest experience with liver transplantation for Amanita poisoning further defines the early clinical and laboratory indications for, and the unique complicating features of, transplantation in this setting.

ACTH (microgram kg-1 i.v.) and prednisolone (1 microgram-1 i.v.) caused a moderate but statistically significant inhibition of rumen contractions, whereas no effects on heart rate and body temperature were observed. Both hormones induced hyperglycaemia and leucocytosis, characterised by moderate lymphopenia and a profound increase in the number of circulating neutrophils. A significant decrease in plasma iron and increase in plasma zinc concentrations were observed. After 3 daily i.m. injections of ACTH (10 micrograms-1 day-1) decreases were seen in both serum Alkaline phosphatase (ALP) activity and plasma trace metal concentrations; heart rate was significantly higher. Intraveneous injection of E. coli endotoxin (0.1 microgram kg-1) caused shivering, fever, inhibition of rumen contractions, changes in heart rate, lymphopenia, neutropenia followed by neutrophilic leucocytosis, hypoferraemia, hypozincaemia, hypoglycaemia and a decline in serum ALP activity. ACTH, given i.m. for 3 days, reduced the febrile responses to E. coli endotoxin, modified the changes in heart rate, intensified the inhibition of rumen contractions, and induced a more marked decrease in the number of circulating neutrophils. ACTH pretreatment did not affect the endotoxin-induced decrease in blood glucose concentrations nor the drop in plasma zinc and iron values. These results suggest that glucocorticosteroids are not primarily involved in the fall in plasma iron and zinc concentrations during E. coli endotoxin-induced fever, the effects of endotoxin released glucocorticosteroids on white blood cells and blood glucose are masked by some other effect(s) of endotoxin, and in dwarf goats, ACTH has antipyretic properties without influencing normal body temperature. This effect is probably not dependent on adrenal cortical activity.

Administration of Bordetella pertussis cell extracts induced in mice hypersensitivity to histamine, as well as pronounced leukocytosis and hypoglycemia. The leukocytosis was mainly caused by an increase in the small lymphocytes in the circulating blood, and it was most pronounced 3 to 4 days after injection of B. pertussis extracts. Rabbit antimouse lymphocyte serum produced a decrease in the lymphocyte count in normal mice, as well as in mice treated with B. pertussis extracts. This depression in lymphocytes was observed whether the antilymphocyte serum was given 1 day or 2 days after the administration of B. pertussis extracts. The increased histamine sensitivity and hypoglycemia of mice treated with B. pertussis extract were not affected by treatment with antilymphocyte serum, although a marked lymphopenia was present. These observations indicate that the three phenomena observed in pertussis-treated mice are independent of each other.

Lambs suffering from Acute Respiratory Distress Syndrome (ARDS) showed elevated PCV, neutrophilia, a tendency towards lymphopenia, eosinopenia, hyperphosphatemia, hypoglycemia and extremely low serum Ca values during the first couple of days after the outbreak of symptoms. During the very early phase, plasma potassium values were mostly lowered (Figs. 1-3, Table I). The possible involvement of histamine is shortly discussed: either 1) through an atopic reaction, 2) because of acute ruminal acidosis and sudden histamine formation, or 3) involvement of endotoxins.

The response of the pony to increasing doses of Escherichia coli endotoxin was evaluated using intravenous and intraperitoneal administration models. Marked changes were seen in all parameters measured following endotoxin administration. Leukopenia (neutropenia, lymphopenia) and thrombocytopenia were not dose-dependent. Similarly, elevated plasma fibrinogen and altered glucose concentrations (hyperglycemia and hypoglycemia), pyrexia and increased lactate/pyruvate ratios were apparent at all endotoxin doses but were not dose related. The widely used packed cell volume and capillary refill time, we well as blood lactate and possibly serum beta-glucuronidase, were increased in a dose-related manner.

Thirty-seven cases of canine hypoadrenocorticism were compared with 39 previously reported cases. The 2 series were compared because it was believed that a study of 37 consecutive cases diagnosed at 1 institution (Michigan State University) and compiled by 1 group of veterinarians would yield data that were more representative of the disease than multiple cases from various institutions. Age, sex, and breed data were similar in both series. The frequency of anorexia, vomiting, depression, and the mean values for the clinicopathologic data were similar for both series except for blood glucose concentration (P less than 0.025). The Michigan State University series was different in that it had a lower frequency of eunatremia, increased plasma total solids, and hypoglycemia but a higher frequency of lymphocytosis, lymphopenia, hyponatremia, hyperglycemia, and hypercalcemia. Further, 3 dogs in the Michigan State University series had azotemia plus near isosthenuric urine, suggesting renal disease, but they seemingly responded to therapy for hypoadrenocorticism. Only 1 such case was identified in the literature. Finally, we detected fewer instances of P waves not being evident in lead II of an electrocardiogram.

Following the Exxon Valdez oil spill, 347 oiled sea otters (Enhydra lutris) were treated in rehabilitation centers. Of these, 116 died, 94 within 10 days of presentation. Clinical records of 21 otters dying during the first 10 days of rehabilitation were reviewed to define the laboratory abnormalities and clinical syndromes associated with these unexpected deaths. The most common terminal syndrome was shock characterized by hypothermia, lethargy, and often hemorrhagic diarrhea. In heavily and moderately oiled otters, shock developed within 48 hours of initial presentation, whereas in lightly oiled otters shock generally occurred during the second week of captivity. Accompanying laboratory abnormalities included leukopenia with increased numbers of immature neutrophils (degenerative left shift), lymphopenia, anemia, azotemia (primarily prerenal), hyperkalemia, hypoproteinemia/hypoalbuminemia, elevations of serum transaminases, and hypoglycemia. Shock associated with hemorrhagic diarrhea probably occurred either as a direct primary effect of oiling or as an indirect effect secondary to confinement and handling in the rehabilitation centers. Lightly oiled otters were less likely to die from shock than were heavily oiled otters (22% vs. 72%, respectively). Heavily oiled otters developed shock more rapidly and had greater numbers of laboratory abnormalities, suggesting that exposure to oil was an important contributing factor.

AIDS-associated Kaposi's sarcoma (AIDS-KS) represents one of the most common malignancies associated with human immunodeficiency virus infection. To target effective therapeutic agents, we have discovered that AIDS-KS cells express high-affinity receptors for interleukin-4 (IL-4), a pleiotropic immune regulatory cytokine. Molecular studies have revealed that AIDS-KS cells express type II IL-4 receptors, in which IL-4 forms a productive complex with primary IL-4 binding protein (IL-4R beta, also known as IL-4R alpha) and a shared subunit between IL-4 and IL-13R systems (IL-13R alpha', also known as IL-13R alpha 1). A recombinant fusion protein composed of IL-4 and a mutated form of a powerful bacterial toxin called Pseudomonas exotoxin (PE)--the fusion protein is termed IL4(3837)-PE38KDEL or cpIL4-PE--was found to be highly and specifically cytotoxic to AIDS-KS cells in vitro. Normal human immune cells (e.g., resting T and B cells and monocytes) or endothelial cells, a possible precursor of AIDS-KS, expressed low numbers of IL-4R and showed little or no sensitivity to cpIL4-PE. Administration of cpIL4-PE in nude mice with established subcutaneously growing AIDS-KS tumors produced remarkable antitumor activity in a dose-dependent manner with the highest dose exhibiting complete responses without any visible toxicity. KS tumors produced metabolic changes including cachexia, hypoglycemia and lymphopenia, all of which were prevented by cpIL4-PE treatment. These studies indicate that cpIL4-PE is a promising experimental therapeutic agent for treatment of AIDS-KS.

A 6-day-old, female roan antelope (Hippotragus equinus cottoni) was diagnosed with a single intrahepatic portosystemic venous shunt at necropsy. Clinical signs had included weakness, lethargy, hypothermia, diarrhea, and a weak suckle response. Multiple seizure episodes were associated with hypoglycemia and characterized by vocalization, muscle fasciculations, and disorientation. Hematologic abnormalities included anemia with hypochromasia, anisocytosis, poikilocytosis, and leukopenia with neutropenia and lymphopenia. Serum biochemical abnormalities included elevations in blood urea nitrogen and total serum bile acid concentration. A portosystemic vascular anomaly should be a differential diagnosis for nonthriving, exotic ruminant calves with overt or subtle neurologic signs, persistent hypoglycemia, and/or elevated bile acids. In very young calves, total bile acid concentration may be more useful in establishing a diagnosis than blood ammonia concentration.
