The five-year experience with 75 consecutive splenectomies has been reviewed. Special detail was given to eight critically ill hypersplenic patients. Their diagnoses included Hodgkin's disease, lymphoma, leukemia, myelofibrosis and Felty's syndrome. Three presented with sepsis, two with anemia not responsive to transfusion, three had pathologic bleeding and two could not receive additional needed therapy of underlying disease because of low counts. All cases responded to splenectomy favorably. Hypersplenism is primarily a loss of balance between the splenic destruction-sequestration and bone marrow production. The demonstrated rapid consumption of transfused cells and some degree of functional reserve of the bone marrow is the prerequisite and clue for splenectomy response in critically ill patients.

Prolonged angiotensin converting enzyme (ACE) inhibition has been consistently demonstrated to increase life expectancy in symptomatic patients with congestive heart failure (CHF), and decrease morbidity in asymptomatic patients with left ventricular (LV) systolic dysfunction. However, prolonged ACE inhibition has not been shown to consistently improve the quality of life of patients with symptomatic CHF. The failure of ACE inhibition to improve quality of life cannot be readily explained, but several factors may contribute to this apparent lack of effect. First, endpoints such as death or hospitalisation are clearly easier to quantify and monitor than a patient's perception of how much CHF affects his/her life. Secondly, while ACE inhibition delays the progression of LV systolic dysfunction, which is the primary determinant of prognosis, it may not reverse the alterations in skeletal muscle vasculature, metabolism and mass, which are primarily responsible for exercise intolerance in patients with CHF. Lastly, patients with CHF, and particularly older patients, are also often incapacitated by other disease processes such as arthritis, loss of balance, pulmonary disorders and anaemia, which, to a large extent, affect the quality of their life more than LV systolic dysfunction and/or CHF.

Butanal oxime is used as a volatile antiskinning agent in paints, inks, and similar products. Butanal oxime was chosen for toxicology testing as a representative of the aldoxime class. Male and female F344/N rats and B6C3F1 mice received butanal oxime (99 percent pure) in drinking water for 15 days or by gavage in 0.5 percent methylcellulose for 14 weeks. Animals were evaluated for clinical pathology, reproductive system effects, and histopathology. Genetic toxicology studies were conducted in Salmonella typhimurium, cultured Chinese hamster ovary cells, and mouse peripheral blood erythrocytes. In the 15-day studies, groups of five male and five female rats and mice received 0, 312, 625, 1,250, 2,500, or 5,000 ppm butanal oxime in drinking water, resulting in average daily doses of approximately 40, 70, or 100 mg butanal oxime/kg body weight to male and female rats; 45, 90, 130, 200, or 300 mg/kg to male mice; and 45, 85, 100, 130, or 170 mg/kg to female mice. Due to body weight loss and lack of water consumption, all male and female rats receiving 2,500 or 5,000 ppm were removed from the study on day 9; average daily doses were not calculated for these groups. All other rats and mice survived until the end of the studies. Mean body weights of 1,250 ppm male and female rats and 2,500 and 5,000 ppm male and female mice were significantly less than those of the controls. Male mice receiving 5,000 ppm and females receiving 2,500 or 5,000 ppm lost weight during the study. Water consumption by rats and mice receiving 1,250 ppm or greater was less than that by the controls. Thinness in 2,500 and 5,000 ppm rats and mice was the only clinical finding of toxicity. Spleen weights were significantly decreased in 2,500 and 5,000 ppm female mice. No chemical-related lesions were observed grossly; histologic examinations were not performed. In the 14-week studies, groups of 10 male and 10 female rats and mice received butanal oxime by gavage at doses of 0, 25, 50, 100, 200, or 600 mg/kg, 5 days per week for 14 weeks. All 600 mg/kg rats died or were killed moribund during the first week of the study; in the 600 mg/kg mouse groups, seven males and nine females died, were killed moribund, or were killed accidentally before the end of the study. Mean body weights of 100 and 200 mg/kg male rats, 600 mg/kg male mice, and female mice administered 50 mg/kg or greater were less than those of the controls. Clinical findings of toxicity in 600 mg/kg rats included loss of coordination, wobbly gait, shaking, blinking, constant grooming and scratching of the face, head weaving, burying of the face in bedding, lethargy, and prostration; in 600 mg/kg mice, clinical findings included ataxia, loss of balance after rearing, squinting, and burying of the face in the bedding. Hematology results of the 14-week gavage studies indicate that butanal oxime induces a methemoglobinemia and a responsive anemia in rats and mice. Spleen weights of 100 and 200 mg/kg male rats, female rats administered 50 mg/kg or greater, and 200 and 600 mg/kg male mice were increased, as were the liver weights of 200 mg/kg female rats and mice. In animals that died early due to butanal oxime administration, hepatocellular necrosis was the primary pathologic finding. Degeneration of the nasal olfactory epithelium was observed in dosed rats and mice that died early as well as in animals that survived to the end of the studies. Additional chemical-related nasal findings were respiratory epithelial changes in male rats and suppurative exudate in male and female mice. Increased incidences and/or severities of splenic hematopoietic cell proliferation and pigmentation (hemosiderin) as well as bone marrow hyperplasia were also observed in dosed groups, particularly in the 200 and 600 mg/kg groups, and were indicative of erythrocyte damage. Butanal oxime (3 to 10,000 ug/plate) was mutagenic in S. typhimurium strain TA1535 in the presence of 5 percent or 10 percent rat liver S9; an equivocal response was seen in TA100 with 30 percent rat S9, and no mutagenic activity was seen in TA98, with or without rat or hamster liver S9. Butanal oxime induced chromosomal aberrations in cultured Chinese hamster ovary cells, with and without S9. Significant increases in the frequencies of micronucleated normochromatic erythrocytes were observed in vivo in peripheral blood of male and female mice administered 25 to 600 mg/kg butanal oxime for 14 weeks by gavage.
