Effects of ursodeoxycholic acid on liver function in patients with cystic fibrosis and chronic cholestasis.

Ursodeoxycholic acid, 10 to 20 mg/kg per day, was administered for 1 year to 22 patients with cystic fibrosis and chronic cholestasis, resulting in significantly improved liver enzyme values. However, evidence of cholestasis continued, as shown by the pattern of alkaline phosphatase isoenzymes.

[Electrical stimulation of the middle ear in total deafness: results in 375 cases (author's transl)].

Electrical stimulation of the middle ear can provoke sound sensations in 90 p. cent of patients with total deafness, as shown by auditory evoked potentials brain stem recordings. This signifies that cochlear nerve destruction is not complete, and rehabilitation by multiple electrode cochlear implants is possible.
