Daily, for 14 days, rabbits of one group were injected with corticotropin, i.e. ACTH-zinc-phosphate (10 units/kg), whereas rabbits of another group were given (in addition) sodium ribonucleate (40 mg/kg) through a tube into the stomach. Formation of lysyl-tRNA, leucyl-tRNA, and alanyl-tRNA in the liver and the skeletal muscles proved to be significantly greater in the animals which received ACTH together with sodium ribonucleate, as compared to that in the animals given the hormone alone. Hyperglycemia, hepatomegaly, and emaciation were less pronounced in the animals given both the preparations.

Chronic selenium (Se) toxicosis was diagnosed in two groups of growing pigs. Emaciation, loss of hair, necrotic areas in the skin, lesions of the coronary band and hooves, postnecrotic atrophic cirrhosis of liver, and lumbal poliomyelomalacia were the principal findings. High Se concentrations were detected in blood plasma. Addition of the calculated amounts of sodium selenite directly to the feedstuff instead to mineral premix was the cause of this intoxication.

An investigation of the pathophysiological characteristics of nursing sickness in mink was carried out as a follow-up study of a previous epidemiological survey at a Danish fur research farm during the 1989 breeding season. In a total of 48 nursing females of the Standard Black and Pastel type, concentrations of several pertinent biochemical constituents of whole blood, plasma, urine and skeletal muscle were determined in order to identify nutritional and metabolic factors involved in the origin and development of the disease. Compared to the reference data obtained in 17 apparently normal lactating dams the findings in 31 females suffering from nursing sickness presented varying clinical and biochemical signs of progressive dehydration and emaciation: aldosteronism, hypovolemia, hyponatremia, hyperkalemia (in the face of muscle potassium depletion), hyperglycemia and azotemic acidemia. Neither ketosis nor severe lactacidemia was observed. The urine was almost devoid of sodium and chloride, and urinary potassium concentration diminished by approximately 50%. The concentrating ability of the kidneys was reduced to less than one third of the maximum value. The results were consistent with severe dehydration and emaciation due to heavy losses of energy, water and body mass along with increasing milk production. The progressive nature of the disease supported the hypothesis that nursing sickness is due to the combined effects of heavy milk production and excessive tissue catabolism along with reduced or ceased dietary intake, and maybe increasing environmental stress. In the advanced stage of the disease coma and death appear to be the inevitable outcome of the metabolic strains for continuing milk production.

A 44-year-old man suffered from repeated impairment of consciousness associated with flapping tremor, myoclonus and generalized convulsions, and died in coma 6 months after admission. He had had a psychosomatically underdeveloped childhood, with a propensity for legumes without a family history of the same or a record of consanguinity. On admission, he had disturbed consciousness and emaciation without other physical abnormalities. The EEG revealed diffuse slow waves with occasional appearance of triphasic waves. A high level of serum citrulline (534.7 nmol/ml) was recognized and the assay of urea cycle enzymes in the liver demonstrated decreased argininosuccinate synthetase (ASS) activity (0.062 U/g liver, 7.4% of that in normal liver), although no kinetic abnormality was found. Accordingly he was diagnosed as having type II citrullinemia. In addition, this case could be classified as cluster type of localization of the ASS in the liver by immunohistochemical study. There were characteristic findings concerning his clinical picture and laboratory data, such as a significant correlation between the grade of disturbed consciousness and arterial blood gas pH (r = 0.61, p less than 0.01). However, the blood ammonia level did not always correlate with the severity of disturbed consciousness. Oral treatment with sodium citrate and sodium benzoate was very effective, though transiently, for disturbed consciousness in this case. Pathological findings of the autopsied liver were fatty change and fibrosis. Neuropathologically, characteristic findings were brain edema with cerebellar tonsilar herniation, laminar necrosis with spongy formation in cerebral cortex, and Alzheimer type II glia. The relationship between citrullinemia and other hepatic encephalopathy was also discussed.

A reproducible experimental disease model in horses using Streptococcus zooepidemicus was developed. An intravenous challenge dose of 1 X 10(10) colony-forming units (CFU), followed 24 h later with another challenge of 1 X 10(8) CFU of Strep. zooepidemicus produced the desired disease model. The disease was characterized by depression, pyrexia, anorexia, abnormal lung sounds, inflammation of joints, moderate to severe lameness, gradual loss of condition and emaciation. The effects of the disease on hematology, serum chemical profile and different protein fractions were studied. The disease state had no effect on serum glucose, sodium, potassium, chloride, urea nitrogen, creatinine, uric acid, calcium, phosphorus and enzymes SGOT or SGPT. However, the alkaline phosphatase showed a gradual decline. The serum iron levels dropped markedly and remained low to the last day of observations (post-infection day, PID 13). On serum protein electrophoresis, the albumin showed a gradual decrease; whereas, alpha II, beta and gamma globulin levels rose suggesting an immune response. The elevation of rectal temperatures and white blood cell counts related well with clinical observations. The serum iron levels proved very helpful in predicting the severity of clinical signs and often dropped before the onset of clinical signs and pyrexia.

Beginning 1 wk postpartum, weekly changes of feed and water intake, body weight, milk production, and electrolyte concentrations in serum, saliva, urine, milk, and feces were observed for 8 to 11 wk. Three dietary treatments differing in sodium chloride and sodium bicarbonate supplementation but containing equal sodium concentrations were used. Dietary chloride percents were low .10%, medium .27%, and high .45%. Consistently changes were significant for feed and water intake, body weight, milk production, and electrolyte concentrations in serum, urine, milk, and feces of cows fed the low chloride diet. By wk 8, body weight had declined from 575.0 +/- 56.7 to 476.7 +/- 54.3 kg, and daily milk production decreased from a peak of 27.7 +/- 2.4 to 19.2 +/- 3.9 kg for cows fed the low chloride diet. Serum chloride decreased from 106.0 +/- 2.8 to 75.5 +/- 6.7 meq/liter during the same time. Cows on the low chloride diet developed clinical signs of a deficiency characterized by depraved appetite, lethargy, hypophagia, emaciation, hypogalactiae, constipation, and cardiovascular depression. Metabolic alterations could be summarized as a severe primary hypochloremic, secondary hypokalemic, metabolic alkalosis.

Chickens treated at seven weeks of age with 150, 200, or 250 mg of crystalline monensin sodium/kg body weight had signs of toxicosis, including extreme weakness, anorexia, paralysis and death. Gross lesions included emaciation, generalized congestion, myocardial enlargement and pallor, and hydropericardium. Samples of ventricular myocardium, superficial pectoralis (white fibers), anterior latissimus dorsi (intermediate fibers), and sartorius muscles (mixed red, intermediate, and white fibers) were examined by light microscope. Intermyofibrillar vacuolation, histochemically positive for neutral fat, was severe in the myocardium and red muscle fibers and moderate in the intermediate muscle fibers. Myofiber necrosis was limited to the red muscle fibers. Mitochondrial degeneration was apparent in myocardial sections from several chickens. Interstitial infiltration by macrophages and heterophils was common in the myocardium and aerobic skeletal muscle.

One hundred fifty lactating mink on one ranch in southern Ontario were monitored over the lactation period in 1989 for evidence of clinical disease, and serial blood samples were collected for biochemical analysis. Antemortem blood samples were collected and necropsies performed on the 17 females that developed nursing disease and on 17 controls matched to the same stage of lactation and on ten nonlactating controls. Twenty-two additional nursing disease cases were selected from seven ranches in the following year and processed similarly. The clinical signs typically observed in affected females were sudden onset lethargy and anorexia followed by dehydration, ataxia, and a reluctance to move. The major clinical-pathologic findings were a marked increase in serum osmolality and total protein, urea nitrogen, creatinine, phosphorus, glucose, and potassium concentrations and a decrease in sodium and chloride concentration. In addition, the animals were acidotic, there was a reduction in the urine specific gravity, and the hemogram was consistent with a stress response. Emaciation and dehydration were the only pathologic changes consistently present in cases of nursing disease and not in controls. In almost all cases, bacteria were not cultured from the liver, spleen, and mammary gland, but Campylobacter jejuni was cultured from the intestinal contents of 15/17 affected mink and 2/5 controls. Aleutian disease virus antibody was not present in any of the affected mink. Lipid vacuoles in hepatocytes and renal tubular epithelium, hypertrophy of cells in the adrenal cortex, and pulmonary congestion and atelectasis were present in both diseased females and controls, as were various sporadic inflammatory lesions. Nursing disease may result from energy depletion due to lactation. All lactating females are affected by this process; clinical disease reflects the terminal physiologic decompensation of the most susceptible individuals.

S-1, an antineoplastic formulation of a fluorinated pyrimidine derivative containing tegafur (FT), CDHP, and potassium oxonate (Oxo) in a molar ratio of 1:0.4:1, was recently developed by Taiho Pharmaceutical Co., Ltd., with the aim of prolonging the effective plasma concentration of 5-fluorouracil (5-FU) over that produced by FT alone and reducing its dose-limiting gastrointestinal toxicity. As a part of the S-1 toxicity study, a 13-week oral repeated dose toxicity study and a recovery study using male and female rats was conducted. Doses of S-1 were adjusted to deliver 1.5, 5, and 15 mg/kg/day as doses of FT, and FT was given at 15 mg/kg/day. The following results were obtained. 1. In clinical observation, edema of the limbs and face or swelling of the auricle of the ear and an anemic appearance were observed in both sexes in the 15 mg/kg/day group as dose of FT. Subsequently, males in this group developed severe anemia, decreased spontaneous motor activity, emaciation, and subnormal skin temperature, and many males died. In the survivors, keratosis of the palm, sole, or tail was observed, with necrosis and loss of the tail tip in the severe cases. 2. Body weight gain was suppressed from about week 2 of treatment in both sexes in the 15 mg/kg/day group as dose of FT, and there was almost no weight gain after week 4-5. Food consumption was consistently less than the control value for males in the 15 mg/kg/day group as dose of FT throughout the treatment period. 3. No marked changes were observed in water intake and on opthalmologic examination. 4. In the fecal test for occult blood, a positive tendency was observed in both sexes in the 15 mg/kg/day group as dose of FT. 5. Urinalysis disclosed a slight increase in protein and decrease in sodium, potassium, and chloride in males, and an increase in protein in females in the 15 mg/kg/day group as dose of FT. 6. Hematologically, both sexes in the 15 mg/kg/day group as dose of FT showed decreases in red blood cell count, hemoglobin, and hematocrit, and increases in platelet count and fibrinogen, with a slight decrease in white blood cell count in males. 7. In the blood biochemical test, abnormal findings included increases in total cholesterol and free cholesterol, and decreases in non-esterified fatty acid and albumin in both sexes in the 15 mg/kg/day group as dose of FT. 8. In organ weight measurement, abnormal changes included a decrease in thymus weight in both sexes in the 5 mg/kg/day or higher dosage groups and a decrease in the testis weight in males and an increase in the liver weight in females in the 15 mg/kg/day group as dose of FT. 9. Histopathologically, both sexes in the 15 mg/kg/day group as dose of FT showed a decrease in the red pulp of the bone marrow, atrophy of the thymus, white pulp of the spleen, and testes. degeneration of the renal tubules, and ulcerative changes of the skin or oral mucosa. 10. The findings were unremarkable in the FT group. 11. During the recovery study, all the toxic effects tended to reverse. 12. The NOAEL of S-1 was estimated to be 1.5 mg/kg/day as dose of FT for both sexes.

Oral single-dose and 13-week repeat-dose toxicity studies of (+/-)-4-ethylamino-1, 1-dimethylbut-2-yn-1-yl 2-cyclohexyl-2-hydroxy-2-phenylacetate monohydrochloride (RCC-36), an active metabolite of (+/-)-4-diethylamino-1,1-dimethylbut-2-yn-1-yl 2-cyclohexyl-2-hydroxy-2-phenylacetate monohydrochloride monohydrate (NS-21), a new drug for the treatment of urinary frequency and incontinence, were conducted in male and female Sprague-Dawley rats. In the single-dose toxicity study, rats were given the drug at doses of 0 (control), 400, 600, 900, 1350 and 2030 mg/kg. In the 13-week repeat-dose toxicity study, rats were given the drug for 13 weeks at doses of 0 (control), 3, 30 and 300 mg/kg. After discontinuation of the treatment, a 5-week recovery test was also conducted. In the single-dose toxicity study, death occurred in the 600 mg/kg group and over, and LD50 values were 735 mg/kg in both sexes. The major clinical signs observed following the administration of this drug were mydriasis, salivation, decreased spontaneous locomotor activity, ataxic gait, lacrimation and urorrhea in the 400 mg/kg group and over, hypopnea and soft feces in the 600 mg/kg group and over. In addition, prone or lateral position and tonic or clonic convulsion were observed in the dead animals. Rats showed a decrease in body weight or a suppression of its weight gain in the 400 mg/kg group and over. Macroscopic findings in the dead animals were congestion in lung and retention of foamy mucinous fluid in trachea. The animals alive showed no abnormalities attributable to the treatment. In the 13-week repeat-dose toxicity study, 13 cases of death occurred in the 300 mg/kg group. Main pathological findings in these cases were congestion and edema in lung. Mydriasis was seen in the 30 mg/kg group and over. Lacrimation, salivation, wheezing, emaciation [corrected] wasting and unkempt fur were seen in the 300 mg/kg. A suppression of body weight gain and a decrease in food consumption were observed in the 300 mg/kg group. An increase in water consumption was seen in the 30 and 300 mg/kg groups. Ophthalmologic examination confirmed the mydriasis in the 30 mg/kg group and over. Urinalysis showed an increase in urine volume and a decrease in Na+ excretion in the 30 and 300 mg/kg groups and decreases in K+ and Cl- excretions in the 300 mg/kg group. Hematological examination showed decreases in hemoglobin, hematocrit, MCV and MCH, and an increase in MCHC in the 300 mg/kg group. Blood chemical examination showed decreases in triglyceride and glucose, and an increase in total protein in the 300 mg/kg group. Pathological examination disclosed hepatocellular hypertrophy associated with hyperplasia of smooth-ER, a decrease in number of glycogen granules and an increase in number of lipofuscin in the 300 mg/kg group. Stimulated thyroid follicles were seen in the 300 mg/kg/group. In kidney, an increase in number of hyaline droplets in the proximal tubular epithelium, in which lysosomes and dense bodies were increased, was observed in the 300 mg/kg group. Dense bodies were increased also in the glomerular epithelium. In this dose group, adrenocortical hypertrophy was also observed. The recovery test showed that the above-mentioned changes were satisfactorily reversible or the degree and frequency of these changes were lowered. No treatment-related effects were seen in the 3 mg/kg group. These results show that the NOAEL (no observed adverse effect level) of RCC-36 is 3 mg/kg for 13-week oral toxicity in rats.
