A method for testing a rat's physical-dependence liability to sedaditive-hypnotic agents and for evaluating that dependence was studied by using the method. Rats received phenobarbital- or barbital-admixed food on a graded-increase dosage schedule over 30-40 days. Manifestations of CNS-suppressing action of either drug (e.g., systemic muscle relaxation, motor incoordination, staggering gait, and ptosis) persisted day and night during the drug medication. Twenty-four to 48 h after withdrawal of either drug, abstinence symptoms (e.g., muscle fasciculation, nuchal twitching, vocalization, increased irritability, ataxia, hyperthermia, and clonic-tonic and grand mal-type convulsions) were evidenced in all animals (N = 6), some of which died after convulsions. These withdrawal signs in rats were classified and found to be closely correlated with the magnitude of weight loss during the withdrawal. The calssification provides a basis for quantitatively assessing physical-dependence liability. The data obtained in the present study suggest that rats, like dogs and monkeys, are suitable experimental animals for tests in early stages of dependence liability, and that the administration of drug-admixed food is a useful method of developing dependence on both barbiturate and morphine-type drugs.

A 24-year-old pregnant woman started to have hyperemesis gravidarum 6 weeks before admission. Four weeks later she had vertigo, diplopia, staggering gait, mild dyspnea, dysphagia, and incontinence of urine. On admission she presented with ophthalmoplegia, ptosis, ataxia, decreased tendon reflex, and memory disturbance. Brain magnetic resonance imaging revealed abnormal intensities in medial thalamic-hypothalamic regions and the periaqueductal area, and she was diagnosed with Wernicke's encephalopathy. Urodynamic studies revealed decreased bladder volume and detrusor hyperreflexia. Six weeks after the administration of 100 mg/day of thiamine, urge incontinence gradually recovered, together with neurological signs. Lesions of the medial thalamic-hypothalamic area and the periaqueductal gray matter seemed to be mainly responsible for micturitional disturbance in our patient with Wernicke's encephalopathy.
