Abstract

The invention discloses a cigarette filter tip, comprising metallothionein. The cigarette filter tip has the advantages of eliminating the gas-phase free radicals in the cigarette flue gas, guarding against damage of cell ingredient and occurring and developing of diseases caused by the gas-phase free radicals in the cigarette flue gas, reducing the aggregation and activation of macrophage in the lung, and guarding against severe damage caused by respiratory burst and releasing active oxygen free radicals.

Description

technical field [0001] The present invention relates to the use of metallothionein, in particular to the application of metallothionein in preparing cigarette filters. The invention also relates to a cigarette filter, in particular to a cigarette filter capable of reducing free radicals in the gaseous phase of cigarette smoke. Background technique [0002] Cigarettes contain a large number of harmful free radicals, including solid-phase free radicals and gas-phase free radicals. Solid-phase free radicals include polycyclic aromatic hydrocarbon free radicals and quinone / semiquinone free radicals, which have the characteristics of long life and stable properties, and can be intercepted by biological filters. The gas phase free radicals include alkoxy free radicals, alkane peroxy free radicals, etc., which have the characteristics of high activity and short life. Gas-phase free radicals can damage cell components, leading to the occurrence and development of diseases. At the ...
