(From Wikipedia, the free Encyclopedia)
Toxins are substances that cause either permanent or reversible injury to the health of a living thing on contact or absorption, typically by interacting with biological macromolecules such as enzymes and receptors. The term is usually reserved for naturally produced substances that kill rapidly in small quantities, such as the bacterial proteins that cause tetanus and botulism. The word "toxic" is used more loosely and often applied to non-biological materials, as in "toxic waste" and "toxicology."
Injestable toxins are also often referred to as poisons, especially when intentionally administered by a human. Animal toxins that are delivered subcutaneously (e.g. by sting or bite) are also called venom. (In normal usage, a poisonous organism is one that is harmful to consume, but a venomous organism uses poison to defend itself while still alive. A single organism can be both.)
Many plants, animals and microorganisms generate toxins to discourage or kill predators. Food poisoning is a term for a broad range of illnesses that can result from eating food that is spoiled or tainted by bacterial toxins, such as botulinum and the so-called Shiga-like toxin secreted by the emergent E. coli strain E. coli O157:H7.
Naturally occurring or human-modified toxins may be intentionally released by humans in chemical warfare.
To see a list of biologically injurious substances, including toxins and other materials, as well as their effects, see poison.

Photodynamic therapy (PDT) is a procedure to treat cancer. Patients are injected with a photosensitizer which is a light sensitive drug selectively retained by cancer cells. When exposed to laser light, the photosensitizer in the cancer cells produces a toxic reaction which destroys the tumor. This photo shows an argon-ion laser, the first component of the argon pumped-dye laser (630nm red). This argon-ion laser emits blue-green light at 488/514 nm, and is used to excite a dye in the second component, the dye laser head, where the wavelength is changed to 630nm red. Different photosensitizers absorb light at different wavelengths. Some absorb light most efficiently in the blue light region of the spectrum around 400 nanometers(nm) with lesser absorption in the green and red light range. However, red light at 630 nm penetrates deeper into the tumor tissue (3-8 mm) than green or blue light. For this reason, the majority of PDT work has used 630 nm light. See artwork: GA-17. Credit: Unknown photographer/artist. | The photo shows the procedure of photodynamic therapy. In this therapy, patients are injected with a light-activated drug called a photosensitizer which makes cells in their body sensitive to light. The drug is selectively retained by cancer cells as compared with normal tissue. Doctors then use fiber-optic probes to expose the cancer to laser light. This activates the photosensitizer and produces a toxic reaction that destroys the tumor without irreparably damaging the surrounding normal cells There is a close-up of just the hands.

Using recombinant DNA technology, a transgenic mouse has been engineered whose bone marrow is protected from the toxic effects of chemotherapy by expression of the MDR 1 gene. This animal system allows rapid screening of drugs which inhibit the multidrug transporter and heralds a new era of using transgenic animals for pharmacologic screening. Multidrug resistance resulting from expression of an energy-dependent drug efflux pump encoded by the human MDR gene is a major impediment to effective cancer therapy.
