Clenbuterol is a β2-agonist and potent selective bronchodilator that is used to treat
bronchospasm in the horse. The drug is normally administered to horses orally as a syrup …

The use of β‐agonists as growth‐promoting agents in cattle could lead to toxic side‐effects
in man. One such effect is the accumulation of polyamines which seem to be implicated in …

Two lines of transgenic mice were produced with constitutive expression of antizyme-1 in the
heart, driven from the cardiac α-myosin heavy chain promoter. The use of engineered …

Polyamines are unbiquitous, naturally occurring small aliphatic, polycationic, endogenous
compounds. They are involved in many cellular processes and may serve as secondary or …

The induction of hypertrophy of cardiac and skeletal muscles has been studied after
treatment with two different salbutamol dosages, therapeutic and doping. Treatment of rats …

Treatment of experimental animals subjected to 90 days physical training programme plus
repeated doses of salbutamol, a β-adrenergic agonist, administered under two different …

This chapter discusses the different types of doping agents that have been used since the
pre-Christian era, such as hallucinogenic mushrooms and alcohol, up to those currently …

Anabolic agents such clenbuterol (Cb) are useful tools for probing the mechanisms by which
muscles respond to disuse. Cb was examined under different loading conditions with …

The role that the induction of cardiac ornithine decarboxylase (ODC), a key enzyme in
polyamine biosynthesis, by beta‐adrenergic agents may have in heart hypertrophy is a …
