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.

Snake bite was diagnosed in 125 dogs and 115 cats over 10 years. Young sporting dogs and young cats were mainly affected. More dogs (48%) were seen in contact with tiger snakes than cats (7%). One hundred and four (84%) dogs and 89 (76%) cats were bitten in the warmer months of the year (October to March). As the incidence rose in September/October, dogs were bitten on days when the temperature was near 20 degrees C or over. The commonest presenting signs were dilated pupils and absences of pupillary light reflex. Dyspnoea, hypothermia, hindleg ataxia and glycosuria were common features in cats. Vomiting, tachypnoea, hyperthermia and complete flaccid paralysis were often seen in dogs. The overall recovery rate after administering antivenene was 90% for cats and 83% for dogs. Death from anaphylaxis as a result of giving antivenene occurred in 3 cats and one dog. Dogs treated soon after being bitten recovered more rapidly. There was no correlation between the bite-to-treatment period and the treatment-to-recovery period for cats.

The convulsant properties of methyl beta-carboline-3-carboxylate (beta-CCM), which is a homologue of a putative benzodiazepine receptor ligand in the mammalian central nervous system, were examined in cats. Subcutaneous injection of 0.5 mg/kg of the beta-CCM produced various degrees of myoclonic jerks always accompanied by cortical spike burst. Some autonomic symptoms such as tachypnea, hypersecretion of thick mucous saliva, vomiting and mydriasis were also presented. Subcutaneous injection of 1.0 mg/kg of the compound induced a generalized tonic-clonic convulsion. Injection of the same amount of the drug 1 hour later in the same cats failed to provoke a generalized seizure. Repeated injection of the same dose 3 hours later provoked a generalized seizure, but with a longer latency. However, repetition of the experiments 24 hours after or 10 days after the first injection consistently induced the same type of generalized seizure with the same latency as the first injections. These results support the suggestion that the pharmacological effect, especially the convulsive effect, of beta-CCM is dose-related, reversible and reproducible in the same cats and among different cats. Moreover, the postictal refractory period in this model of epilepsy may continue about for 3 hours.

Four adults, including a pregnant woman, and three children were admitted to hospital following accidental exposure to mercury vapour produced by heating mercury-gold amalgam. Initial symptoms and signs included a paroxysmal cough, dyspnea, chest pain, tachypnea, nausea, vomiting, fever and leukocytosis. Pulmonary function testing performed on the second day after exposure revealed air-flow obstruction and minor restrictive defects in three patients. The diffusing capacity of the lung for carbon monoxide was reduced in two of these patients. The mean initial blood mercury level (+/- one standard deviation) for the seven patients was 30.8 +/- 1.5 micrograms/dl. A computer analysis showed mercury to behave as a two-compartment system, the compartments having half-lives of 2 and 8 days. The four adults received chelation therapy with D-penicillamine, which did not affect the urinary excretion of mercury. The pregnant woman's infant, born 26 days after exposure, had no detectable clinical abnormalities. The levels of mercury in the blood of the mother and infant at birth and 6 days later were comparable, indicating free transfer of the metal across the placenta.

Nicotine produced a distinct reproducible syndrome in the conscious dog when injected intravenously or intracerebroventricularly. Intravenously administered nicotine (40 micrograms/kg/min for 20 minutes) increased cardiac and respiratory rates and produced analgesia, miosis, hypothermia, behavioral restlessness and emesis. When microinjected into the third cerebral ventricle, nicotine (100-200 micrograms) similarly increased cardiac and respiratory rates and pupillary diameter; and produced behavioral restlessness, emesis, erratic analgesia and maintained wakefulness and a desynchronized EEG. Microinjection of nicotine (5-25 micrograms) into the periaqueductal gray failed to alter any of the parameters studied. Intravenous pretreatment with the opioid antagonist naltrexone (2 mg/kg) influenced the action of intravenous nicotine on certain physiological systems. While naltrexone alone produced a significant degree of tachycardia, miosis, and analgesia, it potentiated the tachypnea and antagonized the miotic response evoked by nicotine. Methionine-enkephalin was detected in perfusates obtained from the lateral cerebral ventricles of conscious dogs. Nicotine produced a non-significant decrease in enkephalin levels. These observations suggest that there are interactions between endogenous opioid and nicotinic processes. However, they are complex and may differ from one functional system to another.

Acute intrinsic renal failure was diagnosed in a two-year-old, male, German shepherd dog following a Vipera aspis bite. Clinical signs included depression, hypersalivation, vomiting, tachypnoea, abdominal pain, splenomegaly, oliguria with haematuria and haemolysed serum. Leucocytosis with a shift to the left, thrombocytopenia, prolonged coagulation times (activated partial thromboplastin time, prothrombin time and thrombin time), hypofibrinogenaemia, azotaemia and hyposthenuria were the most prominent laboratory abnormalities. Histopathological evaluation of the kidneys showed a discrete glomerular hypercellularity, mesangial lysis and renal tubules filled with many hyaline casts and some necrotic cells.

Single dose toxicity studies of T-3761 were carried out in mice, rats and dogs, and the following results were obtained. 1. The approximate lethal dose of T-3761 were more than 5,000 mg/kg for mice and rats, more than 2,000 mg/kg for dogs with oral administration, and more than 5,000 mg/kg for mice and rats with subcutaneous injection. LD50 values with intravenous injection were 783 mg/kg for male mice, 832 mg/kg for female mice, 341 mg/kg for male rats, and 403 mg/kg for female rats. Two dogs given 200 mg/kg did not die but one of the two treated with 400 mg/kg died after intravenous injection. The approximate lethal dose for dog was 400 mg/kg. 2. Neither abnormal symptoms and macroscopic findings nor deaths were observed in mice and rats treated orally. Granuloma around precipitates of T-3761 at the injection site was seen in mice and rats injected subcutaneously. Slight increase of white blood cell count, serum GOT, CPK and urea nitrogen were transiently found in dogs treated orally. Neither abnormal macroscopic findings nor deaths were observed in dogs treated orally. 3. Decreased motor activity and irregular breathing were observed in mice and rats injected intravenously. In dying animals, tonic or clonic convulsions were observed. Vomiting, hyperemia of ophthalmic mucosa, edema of face, decrease of motor activity, salivation and decrease in body temperature were observed in dogs injected intravenously. At higher doses, scream and tachypnea were observed while injecting. Hematological examinations disclosed that increases in red blood cell count, white blood cell count, hematocrit and hemoglobin were found transiently. In biochemical examinations, increases in serum GOT, GPT, urea nitrogen and creatinine were found transiently. One dog intravenously injected 400 mg/kg, showed tonic convulsion and died.

A progressive pulmonary disease resulting in severe respiratory failure and death in an average of 3 weeks was diagnosed in 11 young Dalmatian dogs. The dogs were from 4 litters, all genetically related by a common ancestor. The initial clinical signs were tachypnea and noisy respiration. Respiratory distress developed shortly before death and was characterized by strenuous and rapid respirations, along with cyanosis and vomiting. On blood gas analysis, there were severe arterial hypoxemia, hypercapnia, and marked alveolar-arterial oxygen difference. Radiographically, a diffuse pattern of alveolar, interstitial, and peribronchial densities was observed in the lungs. Most dogs developed pneumomediastinum and gastroesophageal intussusception in the terminal phase of the disease. There was no response to treatment with antibiotics, corticosteroids, diuretics, or oxygen. At necropsy, the lungs were wet, heavy, and relatively airless. Absence of 1 kidney in 2 dogs and severe internal hydrocephalus in 2 dogs were additional necropsy findings. Pulmonary histopathology included metaplasia and atypia of the alveolar and bronchiolar epithelium, a nonpurulent inflammatory reaction characterized mainly by mononuclear cells and macrophages, eosinophilic hyaline membrane formation, and focal pulmonary fibrosis. The histological manifestations were typical of acute lung injury. Clinically, the findings were consistent with adult respiratory distress syndrome (ARDS), except for the relatively long course. No known risk factors for ARDS, such as trauma, toxin exposure, infection, or endotoxemia could be identified. The relationship of the other abnormalities (ie, renal aplasia, hydrocephalus) to the pulmonary disease also remains obscure. An inherited defect is suspected, because segregation analysis of the 4 litters suggests autosomal recessive inheritance.

We prospectively studied 110 adult patients coming to Black Lion Hospital between August 1987 and July 1989 with community acquired pneumonia (CAP) for various etiologic agents and clinical and radiographic presentation. Streptococcus pneumoniae was the most common offending pathogen in 72% and 67.5% from sputum and lung aspirate (LA) Gram stain respectively, and in 41% by pneumococcal serotyping of sputum. Blood and LA culture grew Streptococcus pneumoniae in 4 (6%), Staphylococcus aureus in 4 (6%), Enterobacteriaceae in (3%), Pseudomonas, Klebsiella and Streptococcus viridans in one case each. Non-bacterial pathogens included Mycoplasma pneumoniae in 3 (3%), Influenza A in 4 (4%), Influenza B in 3 (3%) and psittacosis/LGV in 4 (4%). Fever, cough, chest pain, tachypnea and coarse crepitations/bronchial breathing were the most common presenting signs and symptoms. Thirty per cent had associated diarrhoea and vomiting initially and 9% had altered state of consciousness at admission. Six patients came in a state of shock. Thirty-nine per cent had underlying illnesses. Ninety-three per cent had either segmental or lobar consolidation. Parapneumonic effusion occurred in 14%. The mortality was 11%. Tachypnea, the presence of underlying illness, altered state of consciousness, extreme leucocytosis and the presence of bilateral and multilobar lung involvement were found to be signs of poor prognosis. Our finding is similar to those from other African countries, except that we are reporting psittacosis/LGV for the first time in Africa.
