F344/N rats and B6C3F1 mice were exposed to 0, 1, 3, or 6 ppm methyl isocyanate by inhalation for 6 hr on 4 consecutive days. Deaths of rats were observed following 3 ppm exposures, and mice died after exposures to 6 ppm. Deaths appeared to be related to severe respiratory distress. Survivors in high dose groups lost weight initially, then gained weight at rates equal to controls throughout a 91-day recovery period. Lung weights increased significantly in male and female rats exposed to 3 ppm, but no persistent changes in brain, kidney, thymus, spleen, liver, or testis weights were seen in either mice or rats. Blood and serum from male and female rats were taken for clinical pathology and hematology assessments on day 7 of postexposure, the day prior to the first observed deaths of these animals. No changes or only slight changes were seen in measures of serum alanine aminotransferase,
sorbitol dehydrogenase
, alkaline phosphatase, or in blood and brain cholinesterase activities. However, serum creatine kinase increased with dose in both males and females. Blood urea nitrogen, creatinine, and methemoglobin were unchanged. No changes were seen in counts of red blood cells or platelets, or in red cell indices. Hemoglobin concentrations and hematocrits were slightly elevated. No changes were noted in absolute leukocyte counts, but counts of segmented neutrophils increased and
lymphocytes decreased

Flurbiprofen, a potent non-steroidal anti-inflammatory and antipyretic agent, was given as an intravenous infusion (2 mg/kg) followed by a bolus injection of 1 mg/kg six hours later. After drug administration body temperature and rumen contractions were slightly depressed, whereas urea values gradually increased; serum
sorbitol dehydrogenase
(
SDH
) activity, plasma iron concentration and the number of circulating lymphocytes were significantly lower. Intravenous injection of endotoxin from Escherichia coli O111B4 (0.1 microgram/kg) caused shivering, fever, inhibition of rumen contractions, changes in heart rate,
lymphopenia
, neutropenia followed by neutrophylic leucocytosis, changes in urea values, hypoferraemia, hypozincaemia and a decline in serum alkaline phosphatase (ALP) activity, whereas gamma-glutamyltranspeptidase, glutamic oxalacetic transaminase, lactic dehydrogenase and
SDH
values were not significantly altered. Pretreatment with flurbiprofen completely abolished the febrile reactions to endotoxin. The endotoxin-induced inhibition of rumen contractions was only delayed. The drug blocked the initial tachycardia to endotoxin but did not prevent the secondary biphasic increase in heart rate. Flurbiprofen failed to modify the endotoxin-induced decrease in both plasma zinc and serum ALP activity whereas the decline in plasma iron concentration was delayed. After drug pretreatment the changes in circulating white blood cells were more pronounced. These data demonstrate that most of the haematological, blood biochemical and clinical effects of endotoxin cannot be blocked by flurbiprofen, and that these effects are not due to the increase in body temperature alone. Tolerance induced by repetitive daily intravenous administration of endotoxin resulted in an almost complete abolition of all the effects. However, the plasma iron values from tolerant goats were significantly lower than those from non-tolerant animals, which demonstrates that the development of a refractory state can result in modification of this biochemical parameter.

The medical records of 19 horses with acute hemoperitoneum were reviewed. The causes for the hemoperitoneum were idiopathic (8 horses), splenic hematoma with capsular tear (7), bleeding from the reproductive tract (3), multicentric hemangiosarcoma (1), and systemic amyloidosis (1). The affected horses were between 4 and 32 years of age (median 11.5 years). The most consistent findings on initial examination were depression, tachycardia, tachypnea, pale mucous membranes, prolonged capillary refill time, colic, and abdominal discomfort. Less common clinical signs included abdominal distention, profuse sweating, ataxia, and broad ligament mass palpated on rectal examination. Clinicopathologic abnormalities commonly detected were anemia, neutrophilia,
lymphopenia
, thrombocytopenia, hypoproteinemia, hypocalcemia, azotemia, increased creatinine kinase, and
sorbitol dehydrogenase
activity. Hemoperitoneum was diagnosed on the basis of abdominocentesis, transabdominal ultrasonography, and postmortem examination. Sixteen horses were treated, and 3 horses were euthanized at owners' request because of severe clinical signs. The treatment consisted of the administration of intravenous fluids, plasma or blood transfusion, nonsteroidal drugs, antimicrobial drugs, and antifibrinolytic and procoagulant agents. Rapid clinical deterioration was observed in 2 horses, necessitating euthanasia. The remaining 14 horses survived the abdominal bleeding (survival rate 74%) and were discharged 3-15 days (median 7.0 days) after presentation. Postmortem examination of the 6 nonsurvivors showed massive abdominal hemorrhage from splenic hematoma with capsular tear (2 horses), multicentric hemangiosarcoma with liver rupture (1), systemic amyloidosis with splenic hematoma and capsular tear (1), and bilateral ruptured ovarian hematomas (1). In one horse, no origin of the bleeding could be determined during postmortem examination.
