Acute toxicity of cefodizime sodium (THR-221) was examined in mice of both sexes, rats of both sexes (including 5-day-old young), and male dogs. The LD50 values of THR-221 (mg/kg) were as follows: (1) mice: intravenous, 7200 for males and 5000 for females; intraperitoneal, 10500 for males and 11000 for females; subcutaneous, 17500 for males and 16500 for females; and oral, 28000 for males and 29000 for females. (2) rats (adult): intravenous, 7000 for males and 8200 for females; intraperitoneal, 9500 for males and 8800 for females; subcutaneous, 17000 for males and 15500 for females; oral, more than 20000 for both sexes; and intramuscular, more than 3200 for both sexes. (3) 5-day-old rats: subcutaneous, 5278 for males and 5314 for females. (4) male dogs: intravenous, more than 5000. Major changes in general conditions observed in mice and rats were decreased spontaneous activity, lying prone, respiratory changes, staggering gait, clonic or clonic-tonic convulsions, and cyanosis, and in the animals dosed orally, diarrhea or salivation was also noted. The changes in 5-day-old rats were respiratory changes, agony, loss of reflex to an external stimulus, and congestion at the injection site, and those in dogs were vomiting, dryness of the nose, and soft or mucous stools. Autopsies on the mice and rats which died revealed hemorrhage on the brain surface. In addition, the following were seen: intraperitoneal retention of fluid and dark red spots on the abdominal wall (i.p.), subcutaneous retention of fluid or jellylike material and hemorrhage at the injection site (s.c.), and retention of fluid and dark red spots on the mucosa in the digestive tract (mice p.o.). In 5-day-old rats which died, the subcutaneous tissue at the injection site showed hemorrhage macroscopically and inflammatory changes microscopically. Hematological and blood chemical tests performed in dogs showed an increase in white blood cells and changes suggesting anemia, increases in GOT, LDH and ALP activities, and slight changes in urea nitrogen and inorganic phosphorus. In one animal given a low dose of 2500 mg/kg, an increase in GPT activity was also seen. However, these changes were all transient. Microscopic findings in dogs were slight inflammatory changes in the subcutaneous tissue around the injection site.

The clinical, biochemical and pathological effects of the fresh shoots of Chrozophora plicata on Nubian goats and Desert sheep were investigated. The animals were given single or repeated daily doses of 10, 5, 1 and 0.5 g/kg of chrozophora shoots by stomach tube and died at various times post dosing. The main signs of Chrozophora poisoning in both species of ruminants were salivation, dyspnea, bloat, inappetence, dullness, diarrhea, paresis of the hind limbs, recumbency and lateral deviation of the head and neck. The main lesions were hemorrhage in the lungs, heart and kidneys, pulmonary cyanosis and edema, hepatic fatty change and depletion of glycogen, catarrhal enteritis, ascites, hydropericardium and serous atrophy of the cardiac fat and renal pelvis. An increase in the concentration of urea, ammonia and bilirubin and in the activity of GOT and a decrease in total protein were detected in the serum. Hematological changes indicated the development of anemia.

Serum erythropoietin levels were measured by radioimmunoassay in 146 children and young adults with congenital heart disease to assess the relationship between erythropoietin and clinical factors (heart failure, anemia, cyanosis) and hemodynamic variables affecting oxygen delivery and utilization. Erythropoietin values were in the normal range (10 to 30 microU/mL) in 73% (58 of 80) of the patients with and 82% (54 of 66) of those without cyanosis. Elevated erythropoietin values in cyanotic patients were associated with lower mixed venous oxygen saturation and tension than in cyanotic patients with normal erythropoietin levels, even though the degree of polycythemia was similar. In contrast, most of the acyanotic patients who had elevated erythropoietin levels were anemic. Of the blood oxygen measurements, mixed venous oxygen saturation and tension had the closest inverse correlation with erythropoietin values. The normal erythropoietin values in most patients are in accord with other observations that show that an elevation in erythropoietin level in response to hypoxia will be transient if it results in a rise in hemoglobin concentration "appropriate" to the degree of hypoxia. Persistent elevation of erythropoietin in patients with congenital heart disease may indicate harmful impairment of hemoglobin production that is potentially correctable.

In 325 cases of industrial chemical cyanosis notified to Her Majesty's Factory Inspectorate for 1961-80 the incidence of poisonings showed considerable seasonal variation with substantially greater numbers occurring in the summer months. A correlation between the number of poisonings in any one year and the hotness of that summer was also shown. The vast majority of incidents occurred during the manufacture of chemicals or dyestuffs, and two particular workplaces were responsible for 70% of the cases. Poisoning by amino compounds appear to produce early cyanosis whereas poisoning by nitro compounds tended to produce delayed cyanosis. These latter compounds were also more likely to produce anaemia. Methaemoglobin was determined in 45% of cases with results ranging from less than a few per cent to over 50%. Despite concentrations of MetHb over 50%, several workers complained only of headache and their blue appearance.

A case is presented, of idiopathic pulmonary hemosiderosis in a female aged 19 years. The clinical onset occurred at the age of 3 years and the evolution was characterized by subfever, dispnoea, coughing and cyanosis. Radiological examination revealed reticulation and uniform distribution of nodules in both lungs. Other laboratory investigations have revealed hypochromic anaemia, restrictive syndrome and reduction of the maximal ventilation rate with marked arterial hypoxemia. Pulmonary bioptic puncture was performed and the patient died three days after puncture. Histopathologic examination of the bioptic sample and of necroptic specimens revealed fibrotic interstitial nodules filled with siderophages. The small and the median arteries displayed fragmentation of the elastic fibers, and hyperelastosis. The changes oberved allowed to make an exact diagnosis of idiopathic pulmonary hemosiderosis.

Ponies given dried red maple (Acer rubrum L.) leaves at a dose of 3.0 gm/kg body weight became ill and died one to five days after administration of the leaves. Two clinical patterns of disease were seen. Ponies given dried leaves collected after September 15 died by 18 hours, while ponies given dried leaves collected before September 15 became ill with a hemolytic syndrome and died by three to five days. Freshly harvested leaves administered immediately after collection did not produce disease in ponies, but when dried, they became toxic and remained so for at least 30 days. Overnight freezing did not alter the toxicity of the leaves. Leaves were toxic when administered at doses of 1.5 gm/kg of body weight. The clinical signs of ponies with the hemolytic syndrome included polypnea, tachycardia, icterus, cyanosis, scleral petechiation, and brownish discoloration of the urine and blood. Blood changes of ponies with the hemolytic syndrome included anemia, hemoglobinemia, Heinz bodies, depletion of erythrocyte reduced glutathione, increased erythrocyte fragility, and increased serum levels of aspartate amino transferase, sorbitol dehydrogenase, plasma protein, and bilirubin. Lesions of ponies that died from the hemolytic syndrome included icterus, centrilobular hepatic degeneration, hemoglobinemic nephrosis, and erythrophagocytosis by splenic, adrenal, and hepatic phagocytes. Only brownish discoloration of the blood and mild centrilobular hepatic degeneration were observed in the four ponies that died peracutely.

Cyanosis, petechiae, and hemorrhages into the soft tissues and muscles of the neck may be absent after strangulation (throttling) during life, if severe bleeding has happened before. If in severe anemia signs directly or indirectly caused by strangulation have developed, it may be suggested that strangulation occurred during life and persisted for some time.

Xylene is an aromatic hydrocarbon widely used in industry and medical technology as a solvent. Health and safety authorities in most countries, including Australia, recommend a threshold limit value (TLV) of 100 ppm in the working environment. Recently, the amount of the major metabolite of xylene, methylhippuric acid (MHA), in urine has been recommended as a better indicator of exposure. The American Conference of Governmental Industrial Hygienists has recommended an upper limit for this indicator, called a biological exposure index (BEI), of 2.0 g MHA/L urine (SG 1.016). Xylene vapour is absorbed rapidly from the lungs, and xylene liquid and vapour are absorbed slowly through the skin. Of the xylene absorbed, about 95% is metabolised in the liver to MHA and 70 to 80% of metabolites are excreted in the urine within 24 hours. However, the many variables which affect the absorption, metabolism and clearance of xylene include exercise, alcohol intake, cigarette smoking, co-exposure to other solvents, gender, and gastrointestinal, hepatic and renal pathology. Xylene in high concentrations acts as a narcotic, inducing neuropsychological and neurophysiological dysfunction. Respiratory tract symptoms are also frequent. More chronic, occupational exposure has been associated with anemia, thrombocytopenia, leukopenia, chest pain with ECG abnormalities, dyspnea and cyanosis, in addition to CNS symptoms. Concomitant exposure to xylene and other solvents, including toluene, affected hematological parameters, liver size, liver enzymes, auditory memory, visual abstraction, and vibration threshold in the toes. Normal metabolic pathways were altered and significant increases in some serum bile acids may reflect early liver damage.(ABSTRACT TRUNCATED AT 250 WORDS)

Between January 1980 and December 1990, 75 (57.3%) of 131 patients with metastatic gestational trophoblastic tumor had pulmonary metastases detected on plain chest roentgenography at the King Faisal Specialist Hospital and Research Centre. Pulmonary involvement was commonly extensive, with 32 (42.7%) patients having > 10 pulmonary metastases and 45 (60%) patients having a pulmonary lesion > 5 cm in diameter. Greater than 50% lung opacification, mediastinal involvement and pleural effusion were present in 25 (33.3%), 25 (33.3%) and 36 (48%) patients, respectively. Eight (10.7%) patients developed early respiratory failure requiring mechanical ventilation within one month of presentation. The development of early respiratory failure was significantly associated with the presence of dyspnea, anemia, clinical pulmonary hypertension, cyanosis, > 50% lung opacification, mediastinal involvement and bilateral pleural effusion. Because all patients requiring mechanical ventilation died, the use of extracorporeal perfusion should be considered in patients with early respiratory failure.

Flutamide, an anti-androgen used in prostate cancer therapy, is also a derivative of aniline. Mild, usually asymptomatic, methaemoglobinaemia has been reported. We report a patient receiving flutamide therapy who developed cyanosis, dyspnoea and anaemia, initially attributed to marked methaemoglobinaemia by the CO-Oximeter method. An unsuccessful trial of methylene blue therapy led to the finding of marked sulphaemoglobinaemia. Sulphaemoglobinaemia has not previously been reported with flutamide use. Recognition of this association is important, given the refractoriness of sulphaemoglobinaemia to methylene blue therapy.
