RESUMO
The liquid membrane phenomenon in angiotensin converting enzyme (ACE) inhibitors namely, captopril and lisinopril has been studied. Hydraulic permeability data have been obtained to demonstrate the existence of the liquid membrane in series with a supporting membrane generated by the ACE inhibitors. Data on the transport of the relevant permeants in presence of the liquid membrane formed by ACE inhibitors indicate that liquid membrane phenomenon is likely to play a significant role in the action of ACE inhibitors.

Various bacterial and fungal infections associated with non-healing ulcers in cases of leprosy have been reported (G Ebenzer et al, 2000, Rama Ramani et al, 1990). There are no reports of mycetoma associated with leprosy patients in the literature. We report here a case of actinomycotic mycetoma due to Nocardia brasiliensis associated with the non-healing plantar ulcer of a leprosy patient.
