The toxic effects of Adriamycin were studied following i.v. administration of from 10.0 mg/kg to 0.039 mg/kg (200--0.780 mg/m2) to beagle dogs, and from 5.83 mg/kg to 0.625 mg/kg (49.9--7.5 mg/m2) in rhesus monkeys by a variety of short and long term treatment schedules. 5 daily doses and 1 dose every 3 weeks were given for both species and, only in dogs, as single injections, 10 daily treatments and 5 daily doses followed by 9 days rest, repeated 3 times. In both species, short term administration of toxic doses caused weight losses, anorexia, diarrhea, atypical oesophageal and intestinal mucosa, bone marrow hypoplasia, lymphoid atrophy and alopecia. Specific adverse responses seen only in monkeys were hypocalcemia, hypomagnesemia, atypical buccal mucosa and reddish urinary pigmentation. Testicular degeneration and prostatic atrophy were produced in dogs. The triweekly treatment schedule caused an additional toxicity at lower doses. In both species a cardiotoxicity syndrome developed with pulmonary oedema and centrolobular hepatic necrosis, plus focal necrosis and vacuolization in cardiac myocytes. Clinical signs of cardiac dysfunction were EKG arrhythmias in dogs, and peripheral oedema, ascites and hydrothorax in monkeys.

The effects of intraruminal administration of 3-methylindole (3MI; skatole) were determined in goats. The 3MI was given to 4 goats at the dose level of 0.3 g/kg of body weight, to 2 goats at 0.2 g/kg, and to 2 goats at 0.1 g/kg; 3 nontreated goats were used as controls. Clinical signs of acute progressive respiratory tract disease were seen in all treated goats. Goats given the largest dose of 3MI (0.3 g/kg) died between 5 and 11 hours after treatment; those given smaller doses (0.2 and 0.1 g/kg) died between 79 and 92 hours. Increased plasma concentrations of 3MI were detected in goats give 0.1 or 0.2 g/kg within 3 hours after administration. By 24 and 36 hours, the concentrations of 3MI in the plasma decreased to low or nondetectable amounts and remained low for the duration of the experiment. Clinical signs of respiratory distress in the goats progressed after 3MI had been cleared from the plasma. Diffuse pulmonary edema and hydrothorax were extensive in goats which died early in the course of the experimentally induced disease. In goats which died at later stages, the lungs were firm and had less watery transudate. Temporal variations in the nature of pulmonic changes were even more obvious by microscopic examination. Diffuse pulmonary edema was the predominant early change. Small foci of emphysema were apparently caused by overdistention of some clusters of alveoli. Marked septal thickening and proliferation of alveolar cells were the prominent changes in goats which died between 79 and 92 hours after treatment. Incubation of L-tryptophan with caprine ruminal fluid resulted in formation of indoleacetic acid, indole, and 3MI. Similar incubations did not convert indoleacetic acid to 3MI. Control incubations showed 3MI as a fermentation metabolite, indicating it exists in caprine ruminal fluid in vivo. Results demonstrated that goats are susceptible to intraruminal administration of 3MI. The transitory appearance of 3MI in the plasma associated with progressive respiratory tract disease was similar to observations in cattle give 3MI. Clinical signs and lesions seen at necropsy were qualitatively similar to those reported in cattle given tryptophan and indoleacetic acid.

Pulmonary edema and hydrothorax were observed in mature swine that died approximately 5 days after consuming corn screenings. These postmortem observations were reproduced in younger pigs that died within 1 week when fed the corn screenings under experimental conditions. Additionally, pulmonary edema and hydrothorax were induced in a pig that died after receiving 4 daily intravenous injections of fumonisin B1, a toxic metabolite produced by Fusarium moniliforme.

In 1989, corn screenings were associated with acute interstitial pulmonary edema, hydrothorax, and death in swine. Attack rate was 5-50%, case fatality rate was 50-90%, and clinical course was 1-2 days. Screenings from farms with pigs affected with pulmonary edema contained 20-330 micrograms fumonisin B1 per gram. Screenings containing 92 micrograms fumonisin B1 per gram fed to weanling pigs caused pulmonary edema and death. Sterilized corn inoculated with Fusarium moniliforme and diluted 1:1 with clean corn contained fumonisin B1 (17 micrograms/g) and caused acute pulmonary edema when fed for 5 days. Survivors developed subacute hepatotoxicosis with individual hepatocellular necrosis, hepatomegalocytosis, and increased numbers of mitotic figures. Similar liver lesions occurred in pigs given fumonisin B1 intravenously at 0.8 mg/kg body weight for 14 days.

Positive end-expiratory pressure (PEEP) increases central venous pressure, which in turn impedes return of systemic and pulmonary lymph, thereby favoring formation of pulmonary edema with increased microvascular pressure. In these experiments we examined the effect of thoracic duct drainage on pulmonary edema and hydrothorax associated with PEEP and increased left atrial pressure in unanesthetized sheep. The sheep were connected via a tracheostomy to a ventilator that supplied 20 Torr PEEP. By inflation of a previously inserted intracardiac balloon, left atrial pressure was increased to 35 mmHg for 3 h. Pulmonary arterial, systemic arterial, and central venous pressure as well as thoracic duct lymph flow rate were continuously monitored, and the findings were compared with those in sheep without thoracic duct cannulation (controls). At the end of the experiment we determined the severity of pulmonary edema and the volume of pleural effusion. With PEEP and left atrial balloon insufflation, central venous and pulmonary arterial pressure were increased approximately threefold (P less than 0.05). In sheep with a thoracic duct fistula, pulmonary edema was less (extra-vascular fluid-to-blood-free dry weight ratio 4.8 +/- 1.0 vs. 6.1 +/- 1.0; P less than 0.05), and the volume of pleural effusion was reduced (2.0 +/- 2.9 vs. 11.3 +/- 9.6 ml; P less than 0.05). Our data signify that, in the presence of increased pulmonary microvascular pressure and PEEP, thoracic duct drainage reduces pulmonary edema and hydrothorax.

Pulmonary edema and hydrothorax were observed in mature swine that died approximately 5 days after consuming corn screenings. These postmortem observations were reproduced in younger swine (16-24 kg) that died within 1 week when fed the corn screenings under experimental conditions. Additionally, pulmonary edema and hydrothorax occurred in a pig (7.1 kg) that died after receiving 4 daily intravenous injections of fumonisin B1. A fungus was isolated from the corn screenings that is identical to Fusarium moniliforme MRC-826 in colony morphology and under microscopic examination.

This is an autopsy report of multiple primary cancers observed in a patient who had clinically been diagnosed as chronic arsenic poisoning. An 88-year-old man, non-smoker, had worked in an arsenic mine for 6 years from the age of 47. He had undergone operations for Bowen's disease and gastric cancer at ages 80 and 86, respectively. At autopsy, squamous cell carcinoma of the lung and a polypoid lesion in the piriform recess were found. Furthermore, microscopic examination revealed latent prostatic adenocarcinoma and oncocytoma in the kidney. The polypoid lesion of the piriform recess appeared to originate from the duct of the minor salivary gland in the pharynx, showing an adenoid cystic carcinoma-like pattern with squamous cell carcinoma in part. The cause of death was thought to be respiratory failure due to bronchopneumonia and pulmonary edema as well as hydrothorax, and chronic heart failure following ischemic heart disease. Bowen's disease was followed by four internal malignant tumors, even though the etiological relation between these cancers and arsenic is not clear.

N-Methylthiobenzamide (NMTB) and alpha-naphthylthiourea (ANTU) are pneumotoxicants which cause pulmonary edema and hydrothorax. Recently a role was assigned to serotonin (5-hydroxytryptamine, 5-HT) in the pneumotoxic response to ANTU (D.E. Mais and T.R. Bosin, 1984, Toxicol. Appl. Pharmacol. 74, 185-194). We therefore investigated the participation of 5-HT in NMTB-induced pneumotoxicity. Pulmonary clearance of 5-HT was studied after NMTB or ANTU using the rat isolated perfused lung. Lung 5-HT uptake was not depressed 5 hr after ANTU or NMTB, but was depressed 12 hr after compound administration. At both time points lungs were edematous as judged by lung wet weight to body weight ratios. Pretreatment with reserpine, a drug known to deplete 5-HT, did not affect the NMTB-induced decrease in lung 5-HT uptake, but did diminish the increased lung wet weight to dry weight ratios seen after NMTB administration in rats and mice and the increased lung wet weight to body weight ratios in mice. NMTB induces a dose-dependant increase in the incorporation of [14C]thymidine into mouse pulmonary DNA. This increase was attenuated, but not abolished, by pretreatment with reserpine. Reserpine did not alter survival time after NMTB or ANTU and did not shift the 14-day LD50 of NMTB. These data suggest that 5-HT is not a primary mediator in the pneumotoxic response to these thiono-containing compounds.

N-Methylthiobenzamide (NMTB) is a pneumotoxin which causes pulmonary edema and hydrothorax in rodents. Reserpine has been shown to attenuate the pneumotoxicity induced by NMTB. Some of that evidence suggests that the protection afforded by reserpine occurs independently of its capacity to reduce peripheral 5-hydroxytryptamine (5-HT). We therefore investigated 2 other pharmacologic properties of reserpine, namely: (1) its capacity to reduce lung norepinephrine (NE); and (2) its capacity to induce hypothermia, in order to more fully understand its mechanism of protection. Pretreatment of mice or rats with 6-hydroxydopamine at a dose which reduced lung NE by approximately 80% did not affect the pneumotoxic response to NMTB. Thus a decrease in lung NE probably does not account for reserpine's protective effect. An investigation of reserpine's effects on core temperature revealed that mice dosed with a combination of reserpine + NMTB presented with core temperatures lower than mice treated with either compound alone. Mice placed in a cold environment (2 degrees C) and dosed with NMTB presented with hypothermia and an attenuated toxic response to NMTB. Thus a reserpine-induced hypothermia could be allowing for a reduction of NMTB metabolism and consequent diminution of toxicity. These observations suggest that reserpine's capacity to protect animals against NMTB-induced pulmonary edema may in part be due to its capacity to induce hypothermia.

Male and female 16 to 18 month old C3Hf/Bd mice in a dermal carcinogenicity study were moribund or died at earlier time points than the expected 24 to 30 months. Clinical signs observed in both treated and control animals included dyspnea, lethargy, and death. Lesions seen in treated as well as control mice were cardiomegaly with myocardial degeneration and necrosis, hydrothorax and pulmonary edema, and ascites and chronic passive congestion of the liver. Mice were negative for serologic, bacteriologic and microscopic evidence of viruses, bacteria and protozoa which can induce heart lesions. Possible causes of the cardiomyopathy include metabolic, degenerative, genetic or undetermined infectious disease.
