The oral toxicity of the anticonvulsant calcium valproate with selected comparisons to valproic acid and sodium valproate was evaluated in mice, rats and Beagle dogs. Median lethal doses of the three forms of valproate in rodents ranged from 1100 to 3900 mg/kg. Clinical signs in acute studies and reductions in body weight or body weight gain and food consumption at high doses in rats and dogs during 2-, 13- and 52-week studies were considered to be central nervous system related. In the 13-week study in rats (calcium valproate at 200, 400, 800, 1200 and 1600 mg/kg and sodium valproate at 1200 mg/kg), reduced plasma globulin levels and low white blood cell counts due to suppressed neutrophil maturation were noted at doses of 800 mg/kg and higher. Platelet counts were reduced at 1200 and 1600 mg/kg. Testicular atrophy occurred at 1200 and 1600 mg/kg. In dogs given calcium valproate at 100, 200 and 400 mg/kg for 13 weeks, testicular atrophy was seen at 400 mg/kg and mild hepatocellular changes at all doses. In rats given calcium valproate at 125, 250 and 500 mg/kg for 1 year, reduced plasma protein and globulin levels and a dose-dependent increased incidence and severity of atrophic pancreatitis were noted at 250 and 500 mg/kg. Calcium valproate, given for 1 year to dogs at doses of 50, 100 and 200 mg/kg, was well tolerated. These studies indicated that calcium valproate has a toxicity profile similar to other forms of valproate.

A total of 145 BB Wistar diabetic rats, 46 of their nondiabetic siblings, and 43 outbred Wistar rats were autopsied and the frequency of lesions in all organ systems were determined. Common strain-related lesions included pulmonary infections, granulomas, lymphoid hyperplasia, lymphomas, lymphocytopenia, eosinophilia, supradiaphragmatic accessory lobes of the liver, and prostatic atrophy. These suggest some basic strain-related abnormalities of the immune system that were selected by the process of inbreeding. Diabetes-related lesions were insulitis, testicular atrophy, cataracts, hepatic fatty change, pancreatitis, lymphocytic thyroiditis, hypoglycemic brain damage, central pontine myelinolysis, stomach erosions, and idiopathic megacolon. Many of these are sequelae of human juvenile-onset diabetes and support the validity of the BB Wistar rat as an animal model for human diabetes mellitus. The absence of several important sequelae of the human disease (i.e., diabetic nephropathy, atherosclerosis, and severe microangiopathy) suggests a degree of infidelity as a model for human diabetes mellitus. Nonspecific lesions occurring in all three groups of rats included myocardial degeneration and fibrosis, splenic extramedullary hematopoiesis, and chronic progressive glomerulonephropathy.

This study was undertaken to investigate the effects of cyclophosphamide (CP) on spontaneous pancreatitis and testicular atrophy of WBN/Kob rats. CP was given daily in drinking water to groups of 20 male 6-week-old WBN/Kob rats at doses of 0 (control), 1.25 or 2.5 mg/kg for 20 weeks. The final body weight in the 2.5 mg/kg CP group was significantly lower than that in the control group. There were no significant differences in blood glucose levels and weights of the pancreas and testis between groups. On histopathological examinations, pancreatitis and testicular atrophy were noted in each group. However, the incidence of pancreatitis characterized by inflammatory cell infiltration and fibrosis in the 2.5 mg/kg CP group was significantly decreased as compared to the control group. In contrast, testicular atrophy was more severe in the 2.5 mg/kg CP group than in the control group. Thus the results demonstrated that CP has inhibitory effects on the development of pancreatitis and enhancing effects on the development of testicular atrophy in WBN/Kob rats.

A squirrel monkey (Saimiri sciureus) presented with wasting, vomiting and diarrhoea. Haematology revealed elevation of creatinine phosphokinase, lactic dehydrogenase, alanine aminotransferase, amylase and lipase, together with azotaemia and hypoalbuminaemia. Prominent findings were chronic pancreatitis with acinar and ductal plugs, granulomatous and necrotizing peripancreatic steatitis, degenerative myopathy, testicular atrophy, candidiasis and bacterial necrotizing glossitis. Antioxidant analyses revealed low concentrations of serum vitamin E (and apparently A), hepatic selenium and hair zinc. Pancreatitis may have caused malabsorption and maldigestion, associated with deficiency of multiple antioxidants.

Sickle cell disease is a debilitating hematologic process that affects the entire body. Disease manifestations in the abdomen most commonly result from vaso-occlusion, hemolysis, or infection due to functional asplenia. Organ specific manifestations include those involving the liver (eg, hepatopathy, iron deposition), gallbladder (eg, stone formation), spleen (eg, infarction, abscess formation, sequestration), kidneys (eg, papillary necrosis, infarction), pancreas (eg, pancreatitis), gastrointestinal tract (eg, infarction), reproductive organs (eg, priapism, testicular atrophy), bone (eg, marrow changes, avascular necrosis), vasculature (eg, vasculopathy), and lung bases (eg, acute chest syndrome, infarction). Imaging provides an important clinical tool for evaluation of acute and chronic disease manifestations and complications. In summary, there are multifold abdominal manifestations of sickle cell disease. Recognition of these sequela helps guide management and improves outcomes. The purpose of this article is to review abdominal manifestations of sickle cell disease and discuss common and rare complications of the disease within the abdomen.
