Abstract: A teleconference system for N conferees, N being greater than two, includes at least two separate stations. Each station has N conferee positions, confronting a virtual conference space, and corresponding conferee positions at each station have the same relative locations about the virtual conference space. At least one conferee position at each station is adapted to be occupied by a conferee in person. Surrogate conferees, which include a video display, a video camera, and a loudspeaker, occupy each conferee position not adapted to be occupied by a conferee in person. Each video display faces one conferee and displays the image of another conferee at a corresponding position at another station; the loudspeaker reproduces the voice of the other conferee. The video camera forms image signals of the one conferee and couples these signals to the display device of a surrogate conferee at a conferee position corresponding to the position of the one conferee at the other station.

Abstract: An improved method is provided for the chemotherapy of leishmanial infections. The anti-leishmanial agent is encapsulated within liposomes and the liposome-encapsulated drug is injected into the body. Subject use of a liposome carrier has produced marked enhancement of the effectiveness and duration of anti-leishmanial action of meglumine antimoniate, and of sodium stibogluconate, drugs which are recommended widely for therapy of leishmaniasis.
