Patients with anorexia nervosa have concurrent problems of emaciation and depression. Therefore, treatment with medications affecting both weight gain and depression seemed reasonable. Seventy-two anorectic patients were randomly assigned in a double-blind study to receive cyproheptadine hydrochloride, a weight-inducing drug, amitriptyline hydrochloride, a tricyclic antidepressant, or placebo. Overall, cyproheptadine had a marginal effect on decreasing the number of days necessary to achieve a normal weight. There was a differential drug effect present in the bulimic subgroups of the anorectic patients: cyproheptadine significantly increased treatment efficiency for the nonbulimic patients and significantly impaired treatment efficiency for the bulimic patients when compared with the amitriptyline- and placebo-treated groups. The differential cyproheptadine effect on the anorectic bulimic subgroups is the first pharmacologic evidence of the validity of these subgroups. Cyproheptadine had an anti-depressant effect demonstrated by a significant decrease in the Hamilton depression ratings.

A 12-year-old Thoroughbred mare, with a history of anorexia, dramatic weight loss, fluctuating pyrexia and intermittent diarrhoea after an episode of colic, was presented for examination with depression, emaciation and ataxia. Thoracic and abdominal paracenteses yielded copious quantities of inflammatory exudate. Palpation per rectum revealed an enlarged spleen. The primary alterations in haematology included a severe leucocytosis with a left shift, and a hyperproteinaemia characterised by hypoalbuminaemia and hypergammaglobulinaemia. Post-mortem examination revealed a low grade pleurisy and peritonitis with fluid accumulation in both cavities. A suppurative gastritis with full thickness perforations of the stomach wall associated with Gasterophilus intestinalis larvae had extended to the juxtaposed organ initiating an extensive suppurative splenitis. Streptococcus zooepidemicus was cultured.

Seven healthy, adult, crossbred yearling ewes were given (orally) 340 g of locoweed (Astragalus lentiginosus) every day for 10 weeks. Another 7 ewes were not fed the plant, but were housed similarly (controls). Blood samples were obtained once a week to evaluate the mitogen-induced lymphocytic responsiveness. For the locoweed-exposed ewes, there was decreased activity in the presence of phytohemagglutinin (a T-cell mitogen). This effect, although not statistically significant at all times, was consistent and became significant after 7 weeks. A similar response was observed in the blood cell cultures in the presence of pokeweed mitogen, but the differences were not statistically significant at most time points. For the locoweed-exposed ewes there also were gradual numerical decreases in total leukocyte and lymphocytes in peripheral blood. Peripheral leukocytes had cytoplasmic vacuolation. The results indicated that a selective effect may occur on cell-mediated immune responses. Serum proteins and gamma-globulins were not affected by locoweed treatment. Locoweed, certain species of Astragalus and Oxytropis, causes considerable economic loss to the livestock industry of western United States. Locoweed consumption by livestock can result in neurologic problems, emaciation, habituation, and reproductive alterations. The reproductive alterations include abortions, birth defects, and some interference with spermatogenesis and oogenesis. Signs of poisoning are CNS depression, rough dry coat, dull eyes, irregular gait, and excitement when stressed. The microscopic lesions are neurovisceral cytoplasmic vacuolations. Microscopic lesions are also observed in the fetuses and newborns of dams which were fed locoweed.(ABSTRACT TRUNCATED AT 250 WORDS)

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.

Studies on acute toxicities of bestatin (NK421) were carried out in both sexes of mice and rats, and male dogs. NK421 was administered subcutaneously, intraperitoneally and orally in mice and rats, and orally in dogs respectively. Mice and rats were observed for 14 days after treatment and LD50 values were calculated by the probit method. NK421 showed very low toxicity and no death occurred in any species following the oral administration of the maximum dose capable of dosing such as 4 g/kg for mice, 2 g/kg for rats and 1.2 g/kg for dog. General toxic signs seen in mice and rats following subcutaneous and intraperitonial injections were as follows; depression, suppressed movement, piloerection, inhibition of spontaneous movement, anorexia and emaciation. Death occurred within 5 days after administration. The toxic target organs of NK421 were found to be kidney, lymphoid tissue and liver based on histopathological examination of dead animals.

Ten clinically normal male beagle dogs were used in the study. Two dogs served as control, 4 received 2 mg lead/kg daily and 4 received 5 mg lead/kg/daily. Lead was administered for 13 weeks, after which one-half of each experimental group was treated with calcium ethylene diaminetetraacetate (CaEDTA) for 5 days. All animals were then monitored for another 4 weeks. Blood lead levels, haematology, blood glutathione concentration, and the number of bone marrow cells with stainable iron granules were measured weekly during the 18-week experimental period. Clinical signs of poisoning were observed only in one dog in the high dose group after 6 weeks. The signed included emaciation, anorexia, muscular weakness, evidence of abdominal pain and depression. These signs were reversed with cessation of lead dosing and CaEDTA treatment. Blood lead levels and the number of marrow cells with non-haeme iron increased in both lead-dosed groups; nucleated red blood cells increased only in high lead dosed group. There was a trend for an increased packed cell volume in all groups; however, the high lead dosed group did not increase as fast. No significant changes were observed in blood glutathione concentration and in other haematologic parameters. There were no differences in the parameters studied between the dogs treated with CaEDTA and those not so treated. Blood lead levels and the number of nucleated red blood cells decreased after cessation of lead administration and the number of marrow cells with iron also tended to decrease after lead removal.

Six Indonesian buffaloes (Bubalus bubalis) were inoculated intravenously with 10(5) Trypanosoma evansi, examined clinically, haematologically and serologically, and then killed 1, 2, 3, 4, 8 or 12 weeks after infection for detailed pathological study. Relapsing fever was related to the waves of parasitaemia and fluctuations of pulse and respiration rates. Anaemic mucous membranes, depression, weakness, refusal to walk, loss of appetite and emaciation were seen. Body weight, packed cell volume, total platelet and red cell counts, and haemoglobin values were below those of two uninfected control buffaloes, as well as below the normal range; on the other hand antibody titres against T. evansi in infected animals were all above those in controls. Emaciation, serous atrophy of fat, hydropericardium, petechial to larger haemorrhages in the pericardium, pneumonia, congested liver and spleen, oedematous enlargement of the superficial lymph nodes and hyperplastic bone marrow were the major gross pathological changes. Histologically, the severity of the disease increased from 1 to 7 weeks after infection and became less obvious at 12 weeks. The most consistent lesions were interstitial pneumonia, interstitial myocarditis, splenic multifocal necrosis, interstitial myositis and hyperplastic bone marrow. The last three lesions appear not to have been reported previously in T. evansi infection in buffaloes or other animals. The clinicopathological findings in this study show that T. evansi is both an intravascular and extravascular parasite.

Five Holstein Friesian calves varying in age from 7 to 9 weeks old, were suspected of suffering from an inherited granulocytopathy known as bovine leucocyte adhesion deficiency (BLAD). Four of them were examined clinically and at necropsy. The most significant clinical findings were fever, depression, weakness, emaciation, diarrhoea, pseudomembranous gingivitis, loose teeth, respiratory infection and occult blood in the faeces. Significant clinicopathological findings were marked leucocytosis, mainly due to a neutrophilia, hypoalbuminemia, hypogammaglobulinemia, increased alpha- and beta-globulins, elevated alkaline phosphatase enzyme activity, hypoglycaemia, and decreased blood urea concentrations. The necropsy revealed emaciated carcasses, granulomatous to necrotising gingivitis, pseudomembranous to necrotising enteritis with perforations, bronchopneumonia, splenic atrophy, and hypoplasia of the thymus. Histopathological examination supported the macroscopic findings.

Glycogen storage disease type Ia (GSD-Ia) (von Gierke's disease) was identified in two 47-day-old littermate Maltese puppies. The puppies were presented for necropsy with a history of failure to thrive, mental depression, and poor body condition. Gross findings included small body size and emaciation (212 and 246 g versus 595 g for normal littermate), severely enlarged pale livers (48 and 61 g), and pale kidneys. Histologically, there was marked diffuse vacuolation of hepatocytes with large amounts of glycogen and small amounts of lipid. Renal tubular epithelium was mildly to moderately vacuolated. Soft tissue mineralization was present in renal tubules and pulmonary alveolar septa. Biochemical analysis showed that levels of glucose-6-phosphatase were markedly reduced in liver (0.3 and 0.4 microM/minute/g tissue versus 4.7 +/- 1.5 microM/minute/g tissue for controls) and kidney (0.45 and 0.4 microM/minute/g tissue versus 4.1 microM/minute/g tissue for controls) and that glycogen content was increased in liver (9.4% and 9.4% versus 1.3% +/- 1.4% for controls). This is the first confirmed report of animals with glycogen storage disease type Ia.
