Acute and subacute toxicities to cats of T-2 toxin, 12-13 epoxytrichothec mycotoxin from fungi Fusarium species and others, were investigated. Major symptoms of toxicity in cats as the result of T-2 toxin were emesis, vomiting, diarrhea, anorexia, ataxia of the hind legs, discharge from the eyes and ejection of hemorrhagic fluid. Consecutive administration of the crude and pure sample of T-2 toxin in a sublethal dose caused a marked decrease in the number of circulating white blood cells. In the early stage of intoxication, a temporal leukocytosis was observed after each administration. Autopsy revealed extensive cellular damages in the bone marrow, intestine, spleen and lymph nodes. Greatly evident were meningeal hemorrhage of the brain, bleeding in the lungs and vacuolic degeneration of the renal tubles. Mycotoxicological significance of T-2 toxin and related trichothecenes is discussed in relation to the food-borne diseases in humans and farm animals.

Mycophenolic acid (MPA), an inhibitor of purine synthesis, was evaluated for its therapeutic and adverse effects in 29 patients with psoriasis. MPA was administered orally for at least 12 weeks, during which time the daily dose was increased from 1600 to 4800 mg depending on occurrence of adverse reactions. Complete clearing occurred in 1 of the patients, almost complete clearing in 14, definite improvement in 13, slight or doubtful improvement in 1. The full effect of MPA required a median time of 8 weeks (range 5-14). After discontinuing MPA, relapses began at a median time of 4 weeks (range 3-8). The severity of psoriasis was scored on a 0 to 108 scale using a newly devised system. The mean severity and range before treatment was 47 (21-88); after 12 weeks, 15 (0-50). Adjustment of dose on the basis of side effects resulted in a median daily dose of 3600 mg (range 2400-4800 mg; 30-96 mg/kg ideal weight). Characteristic dose-limiting side effects were soft or frequent bowel movements, diarrhea, nausea, and anorexia. One instance of reversible, dose-related leukopenia was identified.

The toxicity of parbendazole in different doses was investigated with 52 horses and 16 ponies, in twelve groups. Side effects observed with the anthelmintic were laxation (soft dung, diarrhoea), anorexia, and listlessness. The seriousness of these symptoms depended greatly on the dose used. Half the therapeutic dose of parbendazole (2.5 to 3.75 mg/kg) administered on two consecutive days led, as a rule, to only slight toxic symptoms and proved highly effective with regard to gastro-intestinal nematodes occurring in horses and ponies. The utilisation of "standard powders" (not commercially available as such) is recommended for simplified dosing (and thus preventing overdosing as far as possible). The laxative side effect of parbendazole was greater during the performing of work (movement). This investigation involved eight Shetland ponies in foal. The pregnancy varied between four and eleven months. No unfavourable effect on the gravidity or on the development of the foetus were observed. Neither clinical examination nor clinical chemical serum examination gave any indication of the occurrence of hyperlipaemia after treatment with parbendazole.

We present the clinical features of Influenzavirus A2 infection in 75 young children admitted to a children's hospital. The most common presenting features were febrile convulsions. vomiting, coughing, diarrhea, and anorexia. At any age, the illness may present with respiratory tract symptoms and signs but in young babies gastroinestinal symptoms are often the presenting complaint. Children aged one to three years often present with febrile convulsions. Only in older children does the adult pattern begin to emerge. Evidence is put forward to suggest that encephalitis in association with influenza can be due to direct invasion of the central nervous system by the virus.

A 5-week-old mixed-breed dog was examined because of emaciation and depression associated with chronic anorexia, diarrhea, and vomiting. Its rectal temperature was subnormal and it died on the day of admission. At necropsy, small focal lesions were distributed through the liver. Enteric alterations included catarrhal enteritis with fluid contents, excess production of mucus, and mucosal hyperemia. Microscopically, the hepatic lesions were disseminated foci of coagulative necrosis, with little or no associated inflammatory cell response. Numerous organisms morphologically consistent with Bacillus piliformis were demonstrated within viable hepatocytes at the periphery of the necrotic foci and in the intestinal mucosa. Numerous coccidial forms were found within the epithelial cells of the intestinal mucosa, which was focally necrotic.

Idiopathic inflammatory bowel disease was the diagnosis for 58 dogs and 26 cats, with signs of persistent gastroenteritis, failed responses to dietary trials, and histologic evidence of cellular infiltrates unrelated to other causes of gastrointestinal tract inflammation. Clinical signs of large intestinal dysfunction, watery diarrhea, vomiting, and anorexia with weight loss were common. Nonspecific hematologic, biochemical, and radiographic abnormalities frequently were observed. Mucosal biopsy specimens, obtained endoscopically, were histologically evaluated for severity of mucosal epithelial damage. Mucosal erythema, friability, enhanced granularity, and ulceration or erosion were the predominant endoscopic lesions. Inflammatory bowel disease lesions of moderate severity predominated in the stomach, duodenum, and colon. Lymphocytic/plasmacytic infiltrates were limited to the lamina propria in biopsy specimens from all regions of the gastrointestinal tract. Inflammatory bowel disease commonly is associated with chronic gastroenteritis in dogs and cats.

The results of treatment of 19 cases of inoperable squamous cell tumors of the head and neck are discussed. The treatment schedule used three drugs: 100 mg/m2 cisplatin at day 1, 25 mg/m2 methotrexate, intravenously, at day 4, and a total of 1000 mg/m2 5-fluorouracil, at days 4-8 of treatment, by continuous 120 hour-long infusion. Effect was observed in 15 patients. The treatment was effective in 47.4% (complete regression--in 1 case, morphologically confirmed and partial regression--in 8 cases), stabilization--in 26.3 (5 patients) and further progression--in 26.3% (5 patients). Among the untoward side-effects were nausea, vomiting, anorexia, stomatitis and diarrhea. The toxicity proved tolerable.

The effects of staphylococci-induced experimental wasting disease on the immune response of 1 month old CD1 mice were investigated. Animals were separated into different subgroups in order to study their cellular immune competence. Malnutrition of wasted mice was associated with anorexia, diarrhea and weakness. Footpad-injected splenic cells produced normal graft vs. host (GvH) reactions in the popliteal lymph nodes of F1 hybrids. In other experiments, the SRBC intragastric feeding of wasted mice did not cause a tolerant anti-erythrocyte humoral immune response. Three weeks after the staphylococci injections, convalescent erythrocyte-fed wasted mice exhibited an anti-SRBC PFC production similar to that observed in non-tolerant immunized control healthy mice. In return, healthy SRBC-fed control mice showed the specific attenuation of antibody response characteristics of oral tolerance. Differences were found between the immune competence of the undernourished staphylococci-treated wasted mice and those shown by other authors in protein-depleted mice.

A 77-year-old female with primary duodenal cancer had undergone pancreatoduodenectomy in May, 1989. Postoperative chemotherapy was done in combination with MMC (mitomycin C), lentinan and UFT (combined medicine of tegafur and uracil). In August, 1991, the patient complained of a cough and then was examined for multiple pulmonary metastases from duodenal cancer by chest X-ray and CT-scan. Then, she received 5'-DFUR (400-800 mg) and MMC (total 6 mg). Two months from the start of this therapy, the cough almost vanished and pulmonary lesions were diminished markedly. For about five months, this case corresponded to partial response (PR) according to the response criteria proposed by Koyama-Saitoh. The side effects of 5'-DFUR were diarrhea and anorexia. Therefore, we think that 5'-DFUR and a small dose of MMC yielded a partial response to multiple pulmonary metastases from duodenal cancer.

Antineoplastic agents affect the healing of intestinal anastomoses. They often induce anorexia and diarrhea, possibly caused by morphological changes in the small intestinal mucosa. These changes were evaluated in the rat ileum. Animals in group I underwent only intestinal surgery while those in groups II and III underwent surgery on the third day of a 5-day course with cisplatin (in two different doses), bleomycin, and 5-fluorouracil. The parameters were: number of mitoses in crypts, crypt depth, villus height, width, and contour length, measured in the mucosa of primarily resected segments of the ileum and of the anastomotic area. Surgery yields an increased crypt depth and villus length in the anastomotic area without changing villus width. The changes in intestinal crypts precede those in villi. Antineoplastic drugs decrease crypt mitotic rate, villus height, width, and contour length. After cessation of antineoplastic chemotherapy mitotic activity increases. The shallower and shorter villi increase in width and length resulting in an increased villus contour length and area. A linear relation exists between villus contour length and villus height and width. Thus, antineoplastic polychemotherapy, dose-dependently, reduces and surgical trauma increases intestinal proliferative activity. However, the morphologic changes do not unequivocally explain possible metabolic disturbances causing retarded intestinal wound healing.
