The numbers of fat macroglobules in peripheral venous blood were recorded for 136 prospectively studied patients with fractures of the pelvis, femur, or tibia. Groups of healthy volunteers and patients undergoing total hip replacement or abdominal surgery served as controls. The highest incidence of fat macroglobulemia occurred in patients with fractures of the femur who also had these clinical signs: petechiae, hypoxia, and depression of the central nervous system. The peak incidence occurred within the first eight hours after fracture. The over-all incidence of fat macroglobulemia in the other surgical patients was roughly equivalent to that in the fracture patients.

The objective of this study was to characterize the hemostatic defect in dogs with infectious canine hepatitis (ICH), a naturally occurring viral disease of dogs. Five littermate dogs were inoculated with 10(3) TCID50 of ICH virus intravenously. Two littermates were controls. The clinicopathologic manifestations of ICH were fever, depression, anorexia, hematemesis, melena, widespread mucocutaneous petechiae, prolonged bleeding from venipunctures, faceial edema, leukopenia, and proteinuria. The hemostatic defect of ICH was characterized by thrombocytopenia, abnormal platelet function, prolonged one-stage prothrombin time and activated partial thromboplastin time, normal thrombin times, depressed factor VIII activity, and increased fibrin-fibrinogen degradation products. These findings suggested that the central pathologic mechanism of the abnormal hemostasis in ICH was disseminated intravascular coagulation (DIC). ICH is an example of DIC induced by viral infection. This disease is a suitable model for investigation of the detection, pathogenesis, and therapy of DIC.

The present study indicates that: (a) local administration of low concentrations of an analog of vasopressin, 1-deamino-[2-phenylalanine, 8-arginine]-vasopressin (DPAVP), constricts venules in the rat splanchnic terminal vascular bed of normal animals, unlike that seen for catecholamines; (b) maximal concentrations of DPAVP narrow but do not occlude both arterioles and venules: (c) microscopic muscular venules (31-39 mu i.d.) do not narrow more than 20% in response to the vasopressin analog DPAVP; and (d) terminal arterioles (17-23 mu i.d.) do not narrow more than 50% in response to DPAVP. Systemic administration of DPAVP to rats subjected to hemorrhage or bowel ischemia shock more than doubles survival rates over control rats receiving Ringer solution. Infusion of DPAVP produces a dose-dependent effect on arterial blood pressure, microscopic capacitance vessels, large arterioles and small arteries. In addition, i.v. administration of DPAVP: (a) returns arterial hematocrit towards normal after shock; and (b) regenerates and sustains vasomotion and venular tone, decreases microvascular hyperreactivity characteristic of shock syndromes, restores constricted arteriolar lumen sizes towards normal, predisposes to a splanchnic microbed virtually free of stasis, petechiae and leukocytic sticking, and restores capillary perfusion and outflow to near-normal. Further, DPAVP effectively restores the early reticuloendothelial system (RES) phagocytic depression, characteristic of shock syndromes, to normal; the latter eventuating in RES hyper-phagocytic activity. These findings indicate it is possible to synthesize vasoactive molecules which: (a) exert selective microvascular and RES phagocytic effects; and (b) are highly beneficial in the therapy of low-flow states, at least in rats.

Eastern equine encephalitis (EEE) was diagnosed in a flock of emus in southeastern Louisiana. The outbreak involved juvenile and adult breeders ranging in age from 20 to 36 months, with an attack rate of 76% and a case fatality rate of 87%. The diagnosis was confirmed by isolation and characterization of the viral agent, and by detection of EEE antibody in two recovered emus. High mortality was preceded by marked depression, hemorrhagic diarrhea, and emesis of blood-stained ingesta. On postmortem examination, hemorrhagic enteritis and multiple petechia of viscera were observed. Microscopic changes included severe necrosis of hepatocytes, intestinal mucosa, and necrotizing vasculitis of the spleen and lamina propria of the intestine. No nervous system lesions were observed. This outbreak occurred concurrently with EEE in horses and was attributed to unseasonably heavy rainfall with an abundance of arthropod vectors and proximity to free-living reservoir host species.

Three neonatal calves ranging in age from 4 to 14 days were examined pathologically and bacteriologically. The calves showed depression, anorexia, pyrexia, and difficulty or inability to stand followed by cloudiness of the ocular aqueous humor or cornea. Autopsy revealed congestion, petechiae, and cloudy areas in the meninges. Histologically, the central nervous system (CNS) lesions were prominent and limited to the meninges where fibrinous exudate and infiltrations of neutrophils, macrophages, and lymphocytes were present. There were mild or slight degrees of choroid plexitis and ependymitis. Endophthalmitis was seen as a concurrent lesion in all cases. Fibrinous or fibrinopurulent changes were found in the peritoneum and epicardium as well as in several other organs. Numerous Gram-positive cocci were detected in affected areas of the whole body. Bacteriologically, Streptococcus bovis was isolated from all examined materials consisting of the brain, cerebrospinal fluid, ocular aqueous humor, and several other organs. These results suggest that the lesions were associated with infection of the organism and that the present cases were in the process of septicemia.

While fat embolism occurs in most (more than 90%) patients with traumatic injury, the fat embolism syndrome (FES) occurs in only 3%-4% of patients with long-bone fractures. FES involves multiple organ systems and can cause a devastating clinical deterioration within hours. The major clinical features of FES include hypoxia, pulmonary edema, central nervous system depression, and axillary or subconjunctive petechiae. Improvements have been made in supporting the respiratory compromise and adult respiratory distress syndrome that these patients develop. Aggressive measures to improve the pulmonary function, i.e., positive pressure ventilation and effective fluid management, are important and expedite fixation of bone fractures.

Fluoxetine (Prozac) is a nontricyclic serotonin (5-hydroxytryptamine) reuptake inhibitor commonly prescribed for the treatment of depression. Fluoxetine also blocks 5-hydroxytryptamine reuptake in platelets and could potentially lead to clinically significant platelet dysfunction. We describe a patient who developed petechiae and prolongation of the bleeding time while receiving fluoxetine therapy.

Pseudorabies virus was inoculated intratracheally into sheep to investigate the pathogenesis of pseudorabies virus infection. Clinical signs of pyrexia, depression, frequent swallowing, facial fasciculations, chorea, excessive salivation, mild tympanites, labored breathing and focal pruritus were followed by death Macroscopic lesions were severe focal facial trauma, petechiae in cervicothoracic ganglia and dilated esophaguses. The medulla oblongata and the trigeminal, cranial cervical, cervicothoracic and parabronchial ganglia contained pseudorabies virus and pronounced nonsuppurative inflammatory changes. The neural distribution of lesions and virus suggests that the virus travelled from the respiratory mucosa to the central and sympathetic nervous system by two routes: 1) in the vagus and glossopharyngeal nerves to the medulla oblongata and 2) in the postganglionic fibers to the sympathetic ganglia. The presence of virus in the nasal mucus indicated that horizontal transmission of pseudorabies virus may occur among sheep.

The administration of estrogen-induced severe bone marrow depression in 9 of 12 ferrets, independent of sex (male, female) or ovariohysterectomy. Resultant pancytopenia was manifested by subcutaneous petechiae, melena, hematomyelia, pale mucous membranes, pale bone marrow, centrilobular hepatic degeneration, hydrometra, and pyometra. These findings are compatible with the naturally occurring estrus-associated anemia seen in female ferrets.

KW2083 7-N-(p-hydroxyphenyl) mitomycin C is a mitomycin C derivative, but not its masked compound. KW2083 differs from mitomycin C in various points. A phase I study of KW2083 by single intravenous injection was performed in 21 patients with advanced solid tumor. The dose limiting factor of this drug is marrow depression, and 70mg/m2 causing marked thrombocytopenia was determined as maximum tolerated dose. The thrombocyte count and the WBC count reached to nadir the minimum 2 to 3 weeks after and 1 to 2 weeks after the administration and recovered in 1 to 2 weeks and in 2 to 3 weeks respectively. As gastrointestinal symptoms, nausea or vomiting (38.1%), and anorexia (28.6%) occurred soon after the administration, and stomatitis and diarrhea were also observed in one case each. In addition, petechia, hemorrhagic tendency and fever were found in one case each. Patients receiving 70mg/m2 showed slight alopecia and transient slight in GOT and GPT elevation.
