Effect of potential antidotes on the acute toxicity of acrylonitrile
1981
Rats were intoxicated with lethal doses of acrylonitrile by different routes of application, and the effect of potential antidotes was studied. The cyanide antidotes 4-dimethylaminophenol plus thiosulfate showed some protective effect only after oral but not after i.p. or inhalatory acrylonitrile application. Of the sulfhydryl compounds cysteine, N-acetylcysteine, cysteamine and diethyldithiocarbamate the two antidotes cysteine and, to some lesser extent, N-acetylcysteine proved especially effective. Cysteine, at a dose of 200 mg/kg (i.p.), prevented the lethal effect of 100 mg/kg acrylonitrile (i.p.) even when given 2 h after the acrylonitrile dose. From these experiments a tentative sched…
Suizidale und parasuizidale Intoxikationen mit Paracetamol
2003
BACKGROUND AND OBJECTIVE: Paracetamol is frequently used in deliberate self-poisoning resulting in a major risk for the patients due to its dose-dependent hepatotoxicity. In the present study the cases of intoxications consulting our Poison Center should be analysed illustrating recent results and trends. PATIENTS AND METHODS: From 38 065 patients (25 098 female, 12447 male, 520 sex unknown, average age 36.8 years) registered during the study period from 1.1.1995 until 31.5.2002 4021 with paracetamol intoxication were analysed with respect to the ingested dose, concomitant substances, the degree of observed symptoms and the length of hospital stay. RESULTS: The use of paracetamol in deliber…
Nitric oxide and sensory afferent neurones modulate the protective effects of low-dose endotoxin on rat gastric mucosal damage
1995
Pretreatment (1 h) with low doses (5-40 micrograms/kg i.p.) of Escherichia coli endotoxin dose dependently reduced the gastric mucosal damage induced by a 10 min challenge with 1 ml ethanol (50% and 100%) in conscious rats. Treatment with the nitric oxide synthesis inhibitor, NG-nitro-L-arginine methyl ester (L-NAME, 5 and 10 mg/kg i.p.), significantly inhibited the protective effects of endotoxin (40 micrograms/kg i.p.). The actions of L-NAME were reversed by the prior administration of L-arginine (100 mg/kg i.p.). The protective effects of endotoxin were not influenced by pretreatment with dexamethasone (5 mg/kg s.c. twice) or indomethacin (5 mg/kg s.c.). However, ablation of sensory affe…
