Lecture 9Malignant tumor and Nutrition
The maximum Japanese cause of one's death terminal cancer is feared because of incurable and acute pain
It is thought that cancer (It is malignant tumorous accurately) happens for the wound to adhere to the gene, and to lose the control of the division with a normal cell. "Carcinogenic gene" that causes cancer is being discovered about 200 kinds now, controls the cell proliferation, and about 20 kinds are known as for "Tumor suppressor gene" that perceives abnormality and restores the abnormality. These genes pile the mutation, and it appears as a sickness that man is made to die. It is thought that it takes time of 15?30 year by the time it counts backward from the speed of the cancer-cell multiplication, one cancer cell is generated, and the human is defeated
Cancer happens because of the change (mutation) in the gene of a normal soma. This is called an initiation
Cancer cell
The occurrence of cancer and abnormality of gene
Abnormality
Cell
Nucleus Base sequence AdenineGuanineCytosineThymine
Passage of carcinogenesis:The long tract of years hangs until getting cancer visible
from the mutation of a gene
Initiation → Promotion → Progrestion
Healthy Cell Cancer CellEarly Stage Cancer Progress Cancer

Clinical periodPossible to discover
Impossible to discover
Precancerous change to a morbid state
Making to cancer happens because of both the oncogene and the tumor suppressor gene mutations
Oncogene and tumor suppressor gene

Cancer gene(accelerator)

Control gene(Brake)
There are an initiator (thing to cause the initiation) and promoter (thing to cause promotion) in the cancer field material in food
The material (mutation field material) that causes the gene abnormality is called and the material that proliferates "Initiator" and a good cancer cell is called "Promoter". "Initiator" includes radiation and ultraviolet rays, virus, and fish's scorch scorching etc.The female hormone and bile acid, high salinity, cigarette, artificial sweetener, agricultural chemicals (DDT ・ BHC), and PCB, etc. are known to "Promoter".

The main tumor marker of cancer according to internal organs
the generation of an active oxygen and a free radical and balance of defense
Injury is generated. Oxidation stress
Injury doesn't occur even if an active oxygen and a free radical have been
generated
In cancer, meal and the cigarette are often causes

Internal organs was excised surgically greatly in the past and it prevented a recurrence. However, it human treats by radiotherapy that keeps qualify of life (QOL).
Digestive tube

Molecule
The organ of importance such as gonads protects only cutting
while irradiating it
Transfusion with marrow 1.5L which the HLA antigen
is near. A normal blood corpuscle is made from the stem cell 1-3 months after
Because the infection resistance power decreases, it puts in an aseptic sickroom,
and the antibiotic and the antibody are used
It is necessary to nurse strong Anorexia and other symptoms in
a large amount of irradiation
The X-ray check is avoided until 2 weeks and 15 weeks of the
pregnancy before the menstruation

A general person during year is 1mSv. The medic assumes 100mSv or less for five years
Lethal dose of whole body(Infection death in several weeks)
The cell of leukemia is irradiated by the twice the lethal dose and the bone marrow transplantation killing afterwards
(Several days after, Diarrhea)

Various following changes
Lymphocyte and a sperm decrease (The number of red blood corpuscles doesn't decrease at once because it has a long life)
The ratio of amount of the focus gland/amount of the skin gland is raised by the multi gate irradiation etc
Erythema and depilation(The hands and feet's irradiation is not fatal)
It irradiates it to cancer 20 times for two months 3Sv
It appears by 5Sv1 1Sv several-time times

Vegetable and grain intake increase
Accomplishment rate 250%
in the cancer field of healthy
people 2000. (green)
A vegetable intake decrease of Japan.
The idea of the adult smoking reducing
by half was deleted in healthy Japan 21.
The cigarette of Japan is 270 yen
a box. Is Europe and
America 700-900 yen a box
To prevent Cancer : 12 Point(The Ministry of Health, Labor and Welfare)
It makes to the table with various foods, and nourishment where be able the balance is taken. It will be conventional. Eating habits with the change are done every day
The delicious one is made a proper quantity. The overeating is avoided, and fat is done with unassuming modesty
Alcohol healthily enjoys the proper quantity
No smoking is borne in mind. Especially, a new smoking habit is stopped
Enough brightly colored vegetables are taken. A lot of vitamin of proper quantity
and fibered things are taken from food Health mind!The body to cleanness
Let's throw a good sweat. and exercise moderately
It doesn't get some sun too much. The sun is a little harmful
The one that mold grew is noted. It checks it without fail before it eats
A burned part is avoided. The mutation is caused
It eats the salty one few, and after it cools it, it eats the too hot one. Treat the stomach and the gullet kindly
