Abstract: A composition for the control of smoking which comprises: (a) a flavonoid in the form of an extract from Eupatorium purpurem preferably euparani; (b) a cytochrome P45C inhibitor (c) a sugar; (d) a source of phosphate; and, optionally, (e) one or more pharmaceutically acceptable carriers.

Abstract: Compositions for the control of smoking are disclosed, the compositions comprising:(a) an xanthine oxidase inhibitor;(b) a phosphate or a compound capable of releasing phosphate on administration to a subject; and optionally(c) a sugar; and still further optionally(d) one or more pharmaceutically acceptable carriers or excipients.There is also described methods for the control of smoking which comprises administering to a subject in need of such treatment the aforementioned composition.

Abstract: Living tissues, such as hybridoma cells or insect cells suspended in a water soluble gelling agent, are microencapsulated in a double polymeric membrane microcapsule. The inner membrane is of a high molecular weight cut-off to permit outward diffusion of the gelling agent and also expansion of the microcapsule before formation of the outer membrane which is a relatively lower molecular weight cut-off. The living cells in the dual membrane microcapsule may be grown to an intracapsular density which is significantly higher than that which can be achieved by using single-membrane capsules. The recovery of intracapsular protein product (produced by the encapsulated cells) is also significantly higher and the loss of product through the membrane wall markedly lower for the dual membrane capsule than for the single membrane capsule.
