Transplants And Diabetes
.... clinically and biochemically permanently normal. Six months later,
Martin examined the cured rats and found intact, functioning islets
secreting all of their hormones, including insulin. None of the controls
were cured.
Encouraged by their first results, Leibel, Martin, and Zingg decided to
repeat the experiment with rats with much stronger immune barriers
(higher levels of rejection). Seven rats out of nine were cured. "We set
up a protocol and worked patiently with small numbers," says Leibel, "but
the results are indisputable."
In addition to reversing diabetes, there are two other benefits to the
pre-treatment proce .....

Iron Absorption From The Whole Diet: Comparison Of The Effect Of Two Different Distributions Of Daily Calcium Intake
.... condition.
The iron inhibition by calcium is a classical example of how the correction of
one nutritional problem can be the cause of another.
The physiological mechanism of this calcium-iron relationship remains a
mystery, however there are two feasible theories. One states that calcium
competes for an iron binding site on intestinal epithelial cells. It is
believed calcium binds to the protein mobilferrin on the epithelial cells, which
is the iron transport protein(Whiting, p.78). Another group of scientists
theorizes that iron is able to be transported into the epithelial cells without
problem, however the iron then has t .....

Gut Issues
.... wonder, then, that dietary fibre has been
unwelcome in many of history's nicer neighborhoods.
Even 20th century doctors reasoned that since the bulky material provided
not a single nutrient, it would only strain already troubled guts.
Accordingly, they recommended low-fibre diets for patients suffering from
hemorrhoids and other colon disorders often found in the West. But then,
about 15 years ago, the prescription was reversed as researchers found
that poor Africans, who eats lots of fibre, rarely suffer from such
complaints. Fibre, the researchers learned, actually eases the bowel's
burden by mixing with water and other foo .....

Necrotizing Fasciitis/Myosits (Flesh Eating Disease)
.... hospitals in times of war. Some outbreaks have occurred also in
civilian populations. There seemed to be some decrease in the 1940's, and
then another outbreak in the 1980's.
Ontario is the only province in Canada where there is statistics on
serious group a streptococcal infections (including necrotizing fasciitis).
These cases are reported to health authorities. Surveillance for group
A streptococcus began in 1991 in Canada. In Ontario, in 1994, 19 cases of
serious disease were reported to health authorities. Of those 19, six
died. There were only 9 cases in 1993, and 27 cases in 1992, and 25 cases
in 1991.

Angina Pectoris
.... is that
coronary heart disease actually accounts for about 80% of all sudden deaths.
In fact, the number of deaths from heart disease approximately equals to
the number of deaths from cancer, accidents, chronic lung disease,
pneumonia and influenza, and others, COMBINED.
One of the symptoms of coronary heart disease is angina pectoris.
Unfortunately, a lot of people do not take it seriously, and thus not
realizing that it may lead to other complications, and even death.
THE HUMAN HEART
In order to understand angina, one must know about our own heart. The
human heart is a powerful muscle in the body which is wor .....

Haemophilia
.... is reduced but in a rare amount of cases, this protein is present
by immunoassay but defective.4 Haemophilia A is the most common severe
bleeding disorder and approximately 1 in 10,000 males is effected. The most
common types of bleeding are into the joints and muscles. Haemophilia is
severe if the factor VIII:C levels are less that 1 %, they are moderate if
the levels are 1-5% and they are mild if they levels become 5+%.5
Those with mild haemophilia bleed only in response to major trauma or
surgery. As for the patients with severe haemophilia, they can bleed in
response to relatively mild trauma and will bleed spontaneous .....

Lassa Fever: An Old World Arenavirus
.... stopped up, with
loads of blood cells and platelets piled well into the arteries and veins.
Fluids and blood filled the lungs. Dead cells and lipids clogged the liver and
spleen. The kidneys were so congested with dead cells and free proteins they had
ceased to function. Dissecting the lymph nodes, they discovered that they were
completely empty; every white blood cell had been utilized in a futile attempt
to stave off the unknown microbe. A few days later, a prominent western viral
researcher contracted the unknown disease and the hunt for the microbe that
caused lassa fever, began in earnest.(Garrett, 1994)
Lassa fever is a vi .....

Leprosy
.... Indonesia, and Myanmar account for almost 70% of the
cases reported in the world. 5500 know cases of Leprosy still exist in the US,
and about 200 cases a reported annually.
Tests to produce leprosy in experimental animals, have not been
successful as of yet. Though the organism can be grown in Armadillos, several
laboratories have been reported cultivating leprosy in the test tube.
Loss of sensation in a patch of skin is often the first symptom that
Leprosy displays. In the lepromatous form, large area’s of the skin may become
infiltrated. The mucous membranes of the nose, mouth, and throat may be invaded
by large numbers .....

Medicine: "Microsurgery: Sew Small"
.... to sew what previously had been
almost invisible blood vessels and nerves in limbs. Their sewing
technique had been developed on large blood vessels over a half century
earlier but could not be used in microsurgery until the needles and
sutures became small enough. The surgical technique, still widely used
today, had taken the frustrating unreliability out of sewing slippery,
round-ended blood vessels by ingeniously turning them into triangles. To
do this, a cut end of a blood vessel was stitched at three equidistant
points and pulled slightly apart to give an anchored, triangular shape.
This now lent itself to easier, mor .....

Leukemia

infection in the wounds, and a very small possibility of obstruction of the
blood vessels.
Treatment of these Leukemias include chemotherapy with alkylafing agents,
or antimetabodies that suppress the growth of abnormal white cells. Another
treatment of some kind would be the x-ray or the administration or radioactive
substances, or radiophosphorus, may be used. After treatment these diseases may
last for many years. Age of the person diagnosed with Leukemia does play an
important part in how that individual responds to any treatment. The older the
person the less response he may have to treatment. Leukemia i .....

Tumours
.... inner core with high
pressure zones that compress and collapse blood vessels, often preventing
the penetration of blood-borne cancer treatments. It spreads to distant
sites by the breaking off of malignant cells, which move through the blood
and lymphatic systems, attach themselves, and begin to grow as new colonies.
Malignant tumours are diagnosed by examination of their vascularity,
shapes, forms of cells division, and differentiation. More than a hundred
different types have been identified in humans. In general, those derived
from epithelial tissue are carcinomas, and those from connective tissue are
sarcomas.
