Phenasepam was studied by the double blind method in comparison with seduxen according to the random principle in 90 males under 60 years of age suffering from ischemic heart disease with psychopathological changes. Phenasepam was given in daily doses of 1.5-4 mg for 3-4 weeks. The psychic condition became normal or considerably improved in 57.2% of patients treated with phenasepam, in 43.8% of those given placebo for phenasepam, and in 21.7% of patients treated with seduxen. Phenasepam caused the best effect in syndromes of pointless anxiety, depression, and cardiophobia. The side-effects (somnolence, listlessness, ataxia) were mild and transient. The authors conclude that it is expedient to use phenasepam in the treatment of psychopathological changes in patients with ischemic heart disease. Psychological factors influencing the therapeutic effect of drugs and its assessment are discussed.

Manganese, zinc and copper are essential for normal prenatal and neonatal development. Manganese deficiency causes skeletal abnormalities, congenital ataxia due to abnormal inner ear development, and abnormal brain function. Depression of mucopolysaccharide synthesis and manganese superoxide dismutase activity may be fundamental to ultrastructural and other defects. In copper deficiency, neurological and skeletal abnormalities are due to impairment of phospholipid synthesis and collagen crosslinking, and possibly to low activity of copper metalloenzymes. The fundamental defect leading to the extremely teratogenic effects of zinc deficiency is related to depressed synthesis of DNA. In the neonatal period, poor survival and growth and depressed function of the immune system are salient features. Developmental patterns of trace element concentrations in various tissues suggest that important changes in metabolic regulation of trace elements may occur during the neonatal period. This hypothesis is being investigated by studies of molecular localization of trace elements in certain neonatal tissues, in conjunction with similar observations in milk.

The effects of clomipramine HCl (15 mg kg-1 i.p.) on behaviour, body temperature and brain amines were investigated in rats that had been chronically treated twice daily with increasing doses of delta 9-tetrahydrocannabinol (delta 9-THC, 2-6 mg kg-1 i.v.). delta 9-THC produced a biphasic change in behaviour, stimulation followed by depression, and a pronounced hypothermia. Tolerance developed rapidly to these effects of delta 9-THC. Chronic treatment with delta 9-THC reduced the levels of homovanillic acid, 5-hydroxytryptamine and noradrenaline. The level of dopamine was not altered with chronic treatment and tolerance appeared to develop to the increased levels of 5-hydroxyindoleacetic acid induced by delta 9-THC. Injection of clomipramine, 12-14 h after 2, 5 or 10 days of delta 9-THC treatment induced characteristic changes in the rats behaviour which consisted of writhes, backward kicking, wet shakes, jumps ataxia and front paw and whole body tremor. The severity of the behavioural changes appeared to be dependent on the period of delta 9-THC administration and they were not accompanied by a change in body temperature or consistent changes in brain amines or metabolites. The results indicate that physical dependence on delta 9-THC may occur since clomipramine is able to precipitate changes in behaviour, indicative on an abstinence syndrome, in rats chronically treated with delta 9-THC. It is suggested that tryptaminergic mechanisms are altered during chronic delta 9-THC treatment and that clomipramine induces the behavioural changes by interacting with an altered tryptaminergic system.

Six Boran steers were infected simultaneously with Trypanosoma congolense and T. brucei brucei while another group of 3 was inoculated with T. b. brucei one year after infection with T. congolense. Three further steers were infected with T. b. brucei alone. Whereas, the six animals which received simultaneous infections developed clinical signs of cerebral trypanosomiasis as evidenced by depression, ataxia and occasional circling, those infected with T. b. brucei alone did not. At necropsy, 4 out of the 6 simultaneously infected animals had a mild to severe disseminated non-suppurative meningoencephalitis. Trypanosoma b. brucei was isolated from the cerebrospinal fluid (CSF) of three out of the four animals with histological lesions. Two of the cattle superinfected with T. b. brucei one year after infection with T. congolense also developed both clinical and histological evidence of cerebral trypanosomiasis. Trypanosoma congolense was isolated from the CSF of one of these 2 animals. Specific antibodies to the variable surface glycoproteins (VSGs) of the infecting T. b. brucei and T. congolense clones were found in the CSF of the 8 animals that developed cerebral trypanosomiasis. In these animals however, there was neither temporal nor quantitative correlation between VSG-specific antibodies in serum and in CSF, implying a de novo synthesis of antibodies to the infecting trypanosomes in the CSF.

In rhesus monkeys, acute administration of levonantradol and nantradol produced signs of CNS depression, including ataxia with body sag, pupil dilation, ptosis, dozing, and reduced responsivity to external stimuli. Neither compound suppressed the morphine withdrawal syndrome; however, both alleviated the chronic abdominal contraction associated with withdrawal. The directly observable effects of these compounds were not antagonized by naloxone. When levonantradol was administered every 6 hours, marked tolerance developed to both the effects of levonantradol and nabilone and THC. No signs of withdrawal were observed when levonantradol injections were abruptly discontinued. When substituted in lieu of codeine under an intravenous drug self-administration procedure, neither levonantradol nor nantradol maintained responding at rates higher than those maintained by their vehicle. Finally, the discriminative effects of levonantradol were not equivalent to those of the narcotics ethylketazocine or etorphine.

Facial hypalgesia, sensory ataxia, depression of tendon reflexes, and masticatory muscle wasting developed acutely to subacutely in three adult dogs. These deficits were correlated with craniospinal sensory ganglioradiculitis. CNS degeneration in the dorsal funiculus, spinal tract of the trigeminal nerve, and solitary tract was secondary to loss of primary sensory neurons. Megaesophagus, which occurred in two dogs appeared to be associated with loss of vagal primary afferent neurons; however, esophageal and gastric myenteric ganglionitis was also observed in one of these animals. In the three dogs changes in the sensory ganglia and roots included non-suppurative inflammation and degeneration and loss of neurons. Perivenular and perineuronal mononuclear infiltrates were prominent. EM study revealed that the satellite cells around degenerating and necrotic cell bodies were commonly invaded and displaced by lymphocytes and macrophages. It was not clear whether these mononuclear cells effected neuronal degeneration or merely responded to it. Although the pathogenesis remained undefined, the similarity of the clinical and pathologic findings in these dogs indicated a nosologic entity that had not been reported previously. This canine ganglioradiculitis was compared with inflammatory disorders of the cranial and spinal ganglia in man.

Strychnine toxicosis is characterized by inducible tetanic seizures and metaldehyde poisoning by fine fasciculations progressing to generalized tremors and seizures. Intoxication with 1080 causes seizures, random running movements, vomiting, defecation, urination, acidosis and hyperglycemia. Intoxication with rodenticides causing coagulopathy is characterized by hemorrhage into body cavities but not necessarily external hemorrhage. Anticholinesterase insecticides cause salivation, urination and defecation, while chlorinated hydrocarbon insecticides cause CNS disturbances. Ethylene glycol intoxication results in ataxia, depression, coma, vomiting and tachypnea, followed by acute renal failure. Urea poisoning causes bloat and CNS signs in cattle. Monensin intoxication in horses lasts several days and causes stiffness, colic, uneasiness and recumbency. Salt poisoning results in depression, seizures and hypernatremia. Lead poisoning is associated with central and peripheral nervous system signs, as well as increased numbers of nucleated RBC and basophilic stippling of RBC. Arsenic poisoning results in GI pain, diarrhea, weakness and death. Copper toxicosis in sheep is manifested by hemolytic anemia, hemoglobinemia and hemoglobinuria. Plants that may intoxicate domestic animals include sorghum, greasewood, halogeton, water hemlock, Japanese yew, larkspur, lupine, milk-weed, philodendron, oleander, castor bean and precatory bean.

Sickness occurred in 3 of 4 horses within 24 h of being sprayed with an 0.025% w/v aqueous suspension of amitraz. The latter consisted of a portion of an amitraz aqueous suspension made up some 3 weeks previously, to which some freshly prepared spray fluid had been added. It seemed likely that the amitraz in the older solution had broken down to the highly toxic N-3, 5- dimethylphenyl N-methyl formamadine derivative and that this was in fact the main cause of the untoward effects observed. The horses displayed typical clinical signs of tranquillisation, depression, ataxia, muscular incoordination and impaction colic lasting up to 6 days. Subcutaneous oedema of the face occurred in one horse. The syndrome was accompanied by mild dehydration and acidosis. All horses survived after persistent symptomatic treatment including the giving of intravenous fluids, enemas, analgesics every 3 h, multiple doses of paraffin oil per os and dexamethasone intravenously. Following the eventual relief of constipation the horses scoured profusely for 24 h before their condition returned to normal.

Naturally occurring cases of poisoning of cattle by Cestrum parqui were characterised by ataxia, depression, recumbency, convulsions and death. Three cattle were dosed experimentally by intrarumenal administration of fresh plant material. One calf died 48 h after receiving 30 g (wet weight) of plant/kg bodyweight. Doses of 11 and 17 g/kg caused only mild intoxication, with dullness and anorexia lasting 2 days. In natural and experimental cases the main lesion was hepatic periacinar necrosis. Elevated levels of plasma aspartate transaminase and prolonged prothrombin times were demonstrated in experimental cases. Haemorrhage beneath the serosa and into the intestinal lumen occurred in field cases, but not in the experimental. It is concluded that C. parqui poisoning in cattle is a primary hepatotoxicity.

Fifteen dogs were given 9.5 ml of ethylene glycol/kg of body weight, orally. Physical examination and clinical laboratory findings were evaluated at 1 and 3 hours after ingestion. Three of these dogs were also evaluated at 6, 9, 12, 24, 48, and 72 hours after ingestion. At 1 and 3 hours, the dogs were depressed, ataxic, and polydipsic with increased urine output and serum osmolality. Plasma bicarbonate and urine osmolality were decreased. The osmolal and anion gaps were increased at 1 and 3 hours, respectively. Calcium oxalate crystalluria was first observed at 6 hours. Diminished renal excretory function was not evident until 48 hours. Depression, ataxia, metabolic acidosis, polydipsia, and polyuria in the presence of serum hyperosmolality were early (1 and 3 hour) findings that indicated ethylene glycol intoxication in dogs.
