Abstract: The invention relates to a ready-for-complexation (RFC) composition, comprising a polyene antimycotic and a cyclodextrin or the derivatives thereof. Also disclosed is a method of using the ready-for-complexation (RFC) composition of the invention to improve the solubility of polyene antimycotic.

Abstract: An assembly includes an exhaust pipe unit and a muffling device. The exhaust pipe unit has at least one gas expanding section. The muffling device includes a muffler unit installed on the gas expanding section of the exhaust pipe unit. The muffler unit has an outer housing surrounding the gas expanding section of the exhaust pipe unit so as to define a gas expanding space in the outer housing, in such a manner that the gas expanding space is communicated with an interior of the exhaust pipe unit. The muffler unit includes a filtering material received within the gas expanding space of the muffler unit so as to filter exhaust gas which flows through the gas expanding space.
