Ten clinically intact weaned piglets were experimentally intoxicated by intravenous injection of lipoproteide-free lipopolysaccharide endotoxin according to Westphal of E. coli O 127:B8. Severe endotoxin shock with all clinical manifestations of experimental coli-enterotoxaemia was induced in all animals and included circulatory disorder with tachycardia, intermittent pallor and/or cyanosis, symptoms of severe systemic intoxication, neurological symptoms, such as lack of coordination, hindleg staggering, spasm, paresis, paralysis, changes in respiration, such as rise in respiratory frequency and deepened breathing premortal deceleration of respiration and gasping for breath, temperature, variation, including hyperthermia and aggravating hypothermia, gastro-intestinal symptoms, such as temporary vomiting and persistent diarrhoea, leucopenia, eosinopenia, variation of haematocrit, edematisation, increased transudation, congestion, and gastro-intestinal shock lesions. Eight animals died. These experiments quite obviously have confirmed that endotoxin shock is the common pathogenetic principle behind all forms of coli-entertoxaemia (i.e, the forms of edematisation, cardiovascular failure, and gastro-intestinal processes.) Lipopolysaccharide endotoxin alone may be responsible for the development of both edemas and neurotoxic symptoms (edema disease) and diarrhoea (gastro-intestinal form of coli-enterotoxaemia). The pathogenetic relevance of additional toxins (neurotoxin and enterotoxin) is discussed under this aspect.

Features of forming and course of ulnar nerve compression neuropathy in the cubital and Guyin's canals were studied in 86 subjects, suffering from occupational diseases of the arms due to vibration and functional overstrain. Compression neuropathy of the ulnar nerve aggravates the vibration disease and arm disorders caused by functional overstrain--increases frequency, intensity and duration of paroxysmal paleness of the IV-V fingers, aggravates paresthesia, hypalgesia and hypothermia of the ulnar antebrachium, markedly decrease power of the hand, which must be taken into account when solving exert problems and carrying out treatment and rehabilitation.

In the attempt to correlate clinical findings with serum levels of aldrin, sixteen patients were followed-up after acute intoxication by this agent. Eight of them, males and females, aged from 1 to 37 years, presented no or light symptoms (some discomfort and nausea). The serum of one of these patients was found to contain 16.6 ppb of aldrin and that of another, 1.41 ppb of dieldrin. A group of five patients, aged from two to 30 years, showed symptoms of moderate severity, reporting nausea, vomiting, drowsiness, dyspnea, sweating, mild jerking, rise in blood pressure and convulsions. Of these cases, two were accidental and three were attempted suicides, the majority achieving complete recovery within 24 hours. Serum levels of aldrin were between 6.98 ppb and 26.3 ppb and of dieldrin between 82.00 and 314.18 ppb. We found three severe cases, aged from 21 to 35 years, two attempted suicides and one occupational case. Two of these patients died and one of them presented hypothermia, coma, absence of reflexes and generalized convulsions, and another presented abdominal pain, paleness, sweating, cold extremities, dyspnea, hyperthermia and generalized convulsions. In the first one that died the serum levels were: of aldrin 30.00 ppb and of dieldrin 720 ppb. In the other levels of 747.3 ppb of aldrin and 1,314.00 ppb of dieldrin were found. The third had less serious symptoms and presented serum levels of aldrin of 31.05 ppb and of dieldrin 147.11 ppb.(ABSTRACT TRUNCATED AT 250 WORDS)

Aqueous and organic extractions of ground seeds of Cassia occidentalis were obtained. Chickens were dosed with extracted material to assess the toxicity of the extracts. Organic extracts with methanol, ethanol, chloroform, ethyl acetate, and benzene were ineffective in removing the toxin from the seeds. Aqueous extractions, using 25 mM sodium bicarbonate or 250 mM sodium citrate, removed the toxin from the seeds, but left the toxin bound to particulate matter in the extract. Addition of Triton X-100 to the aqueous buffers effectively solubilized the toxin from the particulate matter. Signs of intoxication in the chickens were loss of weight, weakness, diarrhea, hypothermia, occasionally ataxia, and recumbency; then death. Gross lesions included paleness of skeletal and cardiac muscles and congestion of the liver. Microscopic lesions in muscle tissue were vacuolation, proliferation of sarcolemmal nuclei, and separation of myofibrils. Electron microscopic examination revealed disruption of mitochondrial cristae and swelling and rupture of mitochondria.

Naphazoline, a sympathomimetic and an imidazoline derivative, is used as 0.05-0.1% solution for local decongestion of the nasal and ocular mucosa. In excessive dosage, or if ingested by accident, may cause depression of the central nervous system (disturbances of consciousness progressing to coma), hypothermia, bradycardia and sweating. These naphazoline effects are particularly strongly pronounced in children. Anglo-Saxon pharmacotherapy excludes the application of naphazoline nasal drops in children younger than six years, whereas the Croatian pharmacotherapeutic literature (and practice) allows its use even in infancy. At the Kantrida Paediatric Clinic, Clinical Hospital Centre in Rijeka, 11 children with signs of intoxication with naphazoline nasal drops were hospitalized from 1990 to 1992. The symptoms pertaining to the central nervous system i.e. disturbances of consciousness in the form of somnolence were clearly marked in all children. Some children developed skin pallor, bradycardia, bradypnoea and hypothermia. Resolution occurred within 24 hours and the findings returned to normal values. Clinical picture followed by rapid resolution and normal findings, with a personal history of drug taking, is a safe indication for diagnosis. There are several reasons to account for intoxication (drops difficult to use with children, containers inadequate for proper dosage), but the major factor is the age of the patient--all hospitalized children were younger than six years. It is pointed out that administration of naphazoline drops at an early age is not advisable.

The case reported here concerns a 40-year-old woman who has suffered from severe migraine without aura since she was 23. The patient has been taking 1-3 suppositories of Virdex (2 mg of ergotamine tartrate, 250 mg of aminophenazone, caffeine) every day for the past three years. In addition to headache, the onset of short, sporadic cramps in the limbs together with paresthesia, hyposthenia, hypothermia and skin pallor with a slight increase in diastolic pressure, made hospital treatment necessary. Instrumental investigation through a stress test on a moving carpet, doppler, echo-doppler and digitalized angiography of the arterial vessels of the lower limbs shows the presence of bilateral impairment attributable to the chronic intake of ergotamine.

In vivo historical control data for Slc: B6C3F1 mice, including mortality, body weight, food and water consumption, and clinical signs and which were obtained from long-term toxicity and carcinogenicity studies (11 male and 12 female studies) conducted at the Biosafety Research Center, Foods, Drugs and Pesticides, (An-Pyo Center) during the last five years are presented. Mean survival at 83 and 109 weeks of age was 96.4% (min: 94.0%, max: 100%) and 79.0% (min: 74.0%, max: 86.0%) in males and 98.7% (min: 96.0%, max: 100%) and 81.7% (min: 70.0%, max: 90.0%) in females, respectively. The maximum mean body weight of males and females was 45.1 +/- 3.1 g (mean +/- S.D.) and 39.2 +/- 4.1 g, respectively. Male mice attained their maximum body weight at 72.7 +/- 4.3 weeks of age and females at 76.2 +/- 5.9 weeks of age. Clinical symptoms increased with age, particularly after week 84, and included: wasting, piloerection and palpable abdominal masses. Hypothermia and auricular pallor were common findings in moribund animals from week 79 to 104 of the studies. The use of in-house, historical control data can prove invaluable in the evaluation and interpretation of experimental results, especially in long-term and life-time studies.

Preparturient hypocalcemia was identified in 4 cats in a specific pathogen-free colony between 1995 and 1996. All cats had an acute onset of clinical signs, 3 to 17 days prior to parturition. Signs of depression, weakness, tachypnea, and mild muscle tremors were the most common clinical signs, following by vomiting and anorexia. Additional abnormalities included hypothermia, third eyelid prolapse, dehydration, pallor, lethargy, flaccid paralysis, and hyperexcitability. Hematologic abnormalities included leukocytosis with neutrophilia and lymphopenia. Hypocalcemia was documented in each queen. Common serum biochemical abnormalities included high aspartate aminotransferase and creatine kinase activities. All cats responded to IV or SC administration of 10% calcium gluconate. Queens were then given calcium orally prior to and following parturition. The queens did not have additional complications for the duration of the gestational or lactational periods.

Subcutaneous fat necrosis (SFN) of the newborn characteristically affects full-term infants who have experienced perinatal distress, such as hypothermia, obstetric trauma, or asphyxia. We report a newborn who had pallor, deep breathing, and severe anemia immediately after birth. She developed SFN on the fourth postnatal day. Her condition improved after blood transfusions and the skin lesions resolved in 6 weeks. This appears to be the first report of SFN associated with anemia.

Brimonidine is an ophthalmic solution of 0.2% brimonidine tartrate used to lower intraocular pressure in human glaucoma patients. A retrospective study was conducted of brimonidine ophthalmic solution ingestion in 52 dogs reported to the ASPCA Animal Poison Control Center between January 1998 and December 2000. Eighty percent of the dogs were < 1-y of age. Approximate ingested dosages ranged from 0.18-5.55 mg/kg. Incidence of clinical signs were bradycardia (67%), depression (46%), ataxia (27%), hypotension (25%), pallor (23%), weakness (17%), change in mucous membrane color (17%), hypothermia (13%), vomiting or retching (13%.). Shock, weak pulses, and poor capillary refill time were also reported. Treatment involved early decontamination, supportive care, andyohimbine and atipamezole as specific alpha-2 antagonists that could be helpful in reversing the effects of brimonidine. Due to the possibility of severe cardiovascular effects developing, the ingestion of brimonidine ophthalmic solution in dogs should be considered dangerous.
