Botox is the abbreviated name for Botulinum Toxin (BT).
Botulinum toxin is the toxic compound produced by the bacterium Clostridium
botulinum. (The names Botox and Dysport are trade names).
It is possibly the most acutely toxic substance known to man; and with a lethal
dose of about 200-300 pg/kg, means that somewhat over a hundred grams could
kill every human living on the earth. Botulin toxin has always been considered
an inferior agent for chemical warfare since it degrades rapidly on exposure
to air, and therefore an area attacked with the toxic aerosol would be safe
to enter within a day or so.
Government Profiting
The government is directly profiting from the sale of animal-tested botulinum
toxin, by manufacturing a botox-type product, Dysport, at its Health
Protection Agency facilities at Porton Down, Wiltshire. The HPA receives a royalty
running into millions of pounds every year from this product.
There
has been a boom in the use of Botox for anti-wrinkle treatments both here and
in the US and a legal loophole in the UK means products such as Botox are not
covered by the ban on animal testing for cosmetic products because they were
initially developed as medicines.
Botox is tested at Wickham Laboratories using the LD-50 test for Ipsen, who
have publically stated that a proportion of their Botox is used for cosmetic
purposes.
Side Effects
Botox does have side effects which can include droopy eyes, headaches, drooling,
flu, respiratory problems, and even temporary paralysis.
Lethal Dose 50 Test
The LD50 test was developed in 1927 and involves dosing several groups of animals
with a substance either by mouth, injection, skin absorption or inhalation.
Animals used have included mice, rats, rabbits, cats, dogs, monkeys, fish and
birds, with the end-point of the assay being when half the animals in the group
have died.
The amount of test substance required to kill half the group is the lethal dose
50% (LD50) figure.
LD50 figures are used to indicate the standard toxicity value for a chemical,
however for a single chemical they can vary enormously according to the species,
strain, age, gender and even diet of the animals used in the test. A comprehensive
report has found that inter-laboratory results for the LD50 figures can vary
by as much as three to eleven-fold.
The LD50 test is carried out to test the safety of drugs, medical devices, industrial
chemicals (including ingredients for household products), food additives, agricultural
chemicals and in some countries for cosmetics ingredients. In terms of LD50
testing for botox the LD50 test can last up to 14 days, during which time animals
experience symptoms such as lung haemorrhage, breathing difficulties, kidney
and liver damage, tremor, incontinence, convulsions, stomach distension and
ulceration, coma and death. No pain relief is normally given.
A body called the Organisation for Economic Cooperation and Development (OECD),
which publishes guidelines describing how various toxicity tests using animals
recommends that a minimum of 20 animals are used for testing botox potency,
with no maximum being set. In the case of Wickham laboratories, documents taken
during an ALF raid have shown that upto 600 mice are used in every day, and
guinea pigs and rabbits are also tested on.
The Home Secretary is responsible for licensing animal experiments in the UK.
Before granting a licence to carry out animal experiments, he must satisfy himself
that certain conditions are fulfilled. In particular, section 5 (5) of the Animals
(Scientific Procedures) Act 1986 (Amendment) Regulations 1998 states:
The Secretary of State shall not grant a project licence unless he is satisfied-
(a) that the purpose of the programme to be specified in the licence cannot
be achieved satisfactorily by any other reasonably practicable method not entailing
the use of protected animals which includes “any living vertebrate other
than man”
(b) that the regulated procedures to be used are those which use the minimum
number of animals, involve animals with the lowest degree of neurophysiological
sensitivity, cause the least pain, suffering, distress or lasting harm, and
are most likely to produce satisfactory results.
In November 1999, the government finally banned the granting of licences for
the LD50 test and all licences issued after September 1998 have been revoked.
However LD50 tests are still permitted for batch-testing procedures such as
is the case for Botox despite there being a humane
alternative.
