Fascioliasis (Fasciola hepatica infection) was diagnosed in a herd of domestic goats in Montana. Twenty-eight goats died after a month-long clinical course of anorexia, weight loss, depression, lethargy, and decreased milk production. Clinical laboratory findings included anemia, low hemoglobin content, hypoproteinemia, hypoalbuminemia, eosinophilia, and high hepatic enzyme activity. The livers of affected goats had extensive parenchymal necrosis, fibrosis, and biliary hyperplasia. Albendazole oral suspension (20 mg/kg) was used to treat 45 of the remaining goats twice, 30 days apart; 15 goats were untreated controls. Egg counts for the untreated group averaged 171 fluke eggs per gram of feces, which compared with less than 1 epg per gram for the treated group. Fifteen percent of the treated goats died, whereas 73% of the untreated goats died. On the basis of necropsy findings, albendazole treatment was regarded as greater than 99% effective against adult F hepatica.

Aplastic anemia in association with estrus was diagnosed in 6 pet ferrets. The ferrets had been examined because of anorexia, depression, and lethargy of 2-5 days' duration. Consistent clinical findings were pale mucous membranes and enlargement of the vulva. Hemorrhages were found in 3 ferrets. Hematologic findings included severe anemia, thrombocytopenia, granulocytopenia, and hypocellularity of the bone marrow. The aplastic anemia was attributed to prolonged estrogenic exposure in ferrets with protracted estrus.

To determine the effect of chlorpromazine on the serum concentration-time curve and metabolism of meperidine, 10 healthy volunteers were injected on two separate days in a two-way crossover design with 26 mg/m2 meperidine hydrochloride combined with either 30 mg/m2 chlorpromazine or a placebo. The subjects demonstrated the same serum meperidine concentration-time curves after meperidine plus placebo and meperidine plus chlorpromazine. The excretion of the metabolites normeperidine and normeperidinic acid, however, showed a significant increase with the meperidine-chlorpromazine combination. A marked lethargy was observed after the administration of the meperidine-chlorpromazine combinations in most subjects, which was quite debilitating and may have resulted from the alteration of meperidine metabolism by chlorpromazine. The meperidine-chlorpromazine combination also caused a greater mean depression of the systolic and diastolic pressures than the meperidine-placebo combination. The differences in the blood pressure and symptomatology were significant and represent a potential toxicity that may result from the use of the chlorpromazine-meperidine combination.

Rats were studied (a) after a single transauricular electroshock (acute ECS) and (b) following 10 consecutive once-daily shocks (chronic ECS). ECS produced a generalized convulsion marked by a polyspike EEG seizure. The seizure was followed by a period of postictal depression (PID) characterized by EEG high-voltage synchrony, EMG quietening, and an associated stuporous behavior in the rat. Acute ECS produced a maximal of 33 +/- 8 (S.E.) percent above control in the EEG voltage output during postictus, with the PID lasting 2680 +/- 658 sec. Chronic ECS resulted in a significant enhancement of these acute responses. Pretreating rats with naloxone (0.3-10 mg/kg s.c.) antagonized the postictal effects of acute ECS, but not of chronic ECS. These naloxone-sensitive postictal EEG and behavioral changes appear to reflect a release of endogenous opioid peptides during ictus, a finding consistent with the hypothesis that electroshock activates opioid systems.

Infection with rickettsiae of the spotted fever group was clinically and serologically diagnosed in four dogs from two households on Long Island. In two dogs, clinical signs included high fever (to 40.5 C), abdominal pain, lethargy, depression, anorexia, and nystagmus. One of these dogs had conjunctivitis and petechial hemorrhages in the oral mucous membranes. The third dog initially had high fever, evidence of abdominal pain, anorexia, and depression. The fourth dog appeared clinically normal. Clinical signs disappeared following treatment with tetracycline given orally.

Trials were conducted in ponies to evaluate the efficacy of pyrantel pamoate (Strongid-T(R)) and two newer anthelmintics not yet commercially available, nitramisole and avermectin B(1)a, against migrating Strongylus vulgaris larvae. Ponies were removed from their mares within 24-48 hr after birth and reared in isolation, worm free. Between six and 14 weeks of age they were infected with 2000 or 2500 infective S. vulgaris larvae. Subsequently, they were monitored daily for clinical signs until the experiment terminated at 28 days postinfection. All ponies showed increased body temperature and reduced appetite within the first week of infection. All anthelmintics were administered on day 7 and in addition pyrantel pamoate was given on day 8 postinfection. The anthelmintics were in liquid formulation. Nitramisole and pyrantel pamoate were given by stomach tube and avermectin B(1)a by subcutaneous injection.Following administration of these compounds toxic reactions were not observed. All anthelmintics caused a reduction in body temperature and increased appetite and effected a clinical cure. In ponies which were not treated with an anthelmintic, temperatures remained elevated and appetites never returned completely to normal. These ponies also showed variable degrees of lethargy, depression, recumbency and colic and the majority died between two and three weeks postinfection. At necropsy, these control ponies showed variable degrees of adhesions involving the abdominal organs, necrosis of the ileum and cecum and severe arteritis and thrombosis of the major abdominal arteries and their branches.Although pyrantel pamoate, used at eight times the therapeutic dose for intestinal nematodes in the horse, effected a clinical cure it did not produce a radical cure. At necropsy, ponies treated with pyrantel pamoate had arteritis and thrombosis of the cranial mesenteric artery and its major branches. Nitramisole and avermectin B(1)a were able to effect both a clinical and radical cure.

Single-treatment schedules in mice and dogs and multiple-treatment schedules in dogs and monkeys were used to evaluate the toxicity of 2,3-dihydro-1H-imidazo[1,2-b]pyrazole. The LD50 of the iv single dose in male and female mice collectively was 993 mg/kg (2980 mg/m2). The major target organs in mice, dogs, and monkeys were the bone marrow, lymphoid tissue, and gastrointestinal tract. Clinical signs at lethal and high toxic doses were weight loss, diarrhea, hematochezia, emesis, anorexia, mydriasis, dyspnea, lethargy, and stupor. The immediate toxic effect on blood cells was a depression of rbcs with suppression of lymphoid elements occurring later. In dogs, the most toxic schedule was single bolus injections. Attenuation of toxic responses occurred if rest periods were introduced between single or repeated daily dose schedules. The monkeys were more sensitive than the dogs to the high toxic dose on a milligram per meter squared basis, with similar sensitivity to the low toxic dose in the repeated daily injections.

A total of 42 patients with atherosclerotic--and 34 with involutional depression were studied by conjunctival biomicroscopy for particular features of lipid peroxidation and state of microcirculation before and after treatment with vasoactive preparations, antioxidants and calcium antagonists. POL were found to be increased in patients with atherosclerotic depression irrespective of the syndrome, and in involutional depression with anxious symptomatology, as well as in those patients in stuporous state, this being accounted by a decreased provision of the organism with antioxidants as well as by an inadequate activity of antioxidant enzymes; high incidence rate of intravascular and vascular changes was also noted in the above patient populations. Tocoferolum acetatum and corinfar potentiated antiaggregational and spasmolytic actions of vasoactive preparations, which fact made for an earlier eradication of microcirculatory disturbances, decrease in the free radical oxidation activity and recovery of those patients getting out of the psychotic state.

475 patients with stomach ulcer (1984-1993) were studied using various methods: endoscopical, immunological, biochemical, bacteriological and morphological. Morphology of exacerbation and type of reparative processes in normal scarring and torpid course of disease are presented. Under adequate regeneration there is an activation of immune system, first that of T-cell compartment. Torpid course is characterized by a grave regeneration disturbance and depression of the immune system. The interpretation of the so-called "red scar" is given: it reflects different stages of the epithelial regeneration, however in 4.8% of duodenal ulcers and in 11.2% of stomach ulcers it masks a torpid course. Helicobacter pylori has no influence on the reparative processes. Adequately chosen therapy improves and accelerates ulcer scarring.

Serum alpha-mannosidase activity and swainsonine concentration were determined in 4 cattle and 15 sheep (3 groups of 5 each) that were administered ground locoweed (Oxytropis sericea or Astragalus lentiginosus) containing swainsonine at dosages of approximately 0.8 mg/kg of body weight/d (cows, 30 days each) and 0, 1.0, and 1.5 mg/kg/d (sheep, 11 days each). The cattle developed mild clinical signs of locoism, including signs of depression, lethargy, and slight intention tremors. Clinical signs of toxicosis were not observed in the sheep. Within 24 hours of initial treatment, serum alpha-mannosidase activity in cows and sheep, measured by the release of 4-methylumbelliferone from an artificial substrate, was markedly decreased to 28 and 40 mumol of 4-methylumbelliferone/L, respectively. Mean serum alpha-mannosidase activity of control cows and sheep was 400 +/- 94 and 422 +/- 42 (mean +/- SD), respectively. In the treated animals, decreased serum alpha-mannosidase activities returned to normal or higher activities within 6 days after treatment was discontinued. Using a jack bean alpha-mannosidase assay, increased swainsonine activity (153, 209, and 381 ng/ml, respectively) was detected in the serum of cattle and of sheep in the high- and low-dose groups within 24 hours after treatment with locoweed. Swainsonine concentration remained high, with mean concentrations of 204, 432, and 395 ng/ml (cows and 2 sheep groups, respectively) during the treatment period. After treatment, swainsonine was rapidly cleared, with estimated serum half-life of 16.4, 17.6, and 20.3 hours (cows, and high- and low-dose sheep groups, respectively).(ABSTRACT TRUNCATED AT 250 WORDS)
