HIJAMAH THERAPY AND THE LIFE CYCLE OF
A RED BLOOD CELL
Many Hijamah
practitioners fall into the trap of calling back patients for remedial therapy
without the patient having adequate healing time from a previous session.
The minimum
time span should be 4-6 weeks before another session should be administered .
Most therapists do not have the knowledge or reasoning as to why i advise this
to patients.
We must
understand the concepts of the formation of Red Blood Cells...Otherwise it is
futile for patients to undertake the treatment of wet cupping therapy
(Hijamah).
Let us take
a look at the physiology of a Red Blood Cell (RBC)
During its
approximately four-month lifespan, the human red blood cell (RBC) travels
approximately 300 miles, making approximately 170,000 circuits through the
heart, enduring cycles of osmotic swelling and shrinkage while travelling
through the kidneys and lungs, and an equal number of deformations while
passing through capillary beds . It has been speculated that accumulated damage
to the RBC, especially to its membrane, renders the aging RBC unfit to
circulate, leading to its destruction, via mechanisms that are poorly
understood.
The normal
time of RBC senescent (age-related) death in adults is approximately 110 to 120
days. Hemolysis can therefore be arbitrarily defined as a shortening in the
survival of circulating RBCs to a value of less than 100 days.
This short
life span necessitates the process erythropoiesis, which is the formation of
red blood cells. All blood cells are formed in the bone marrow. This is the
erythrocyte factory, which is soft, highly cellar tissue that fills the
internal cavities of bones.
During
intrauterine development, the early stages of life, erythrocytes are produced
first by the yolk sac and then by the developing spleen during the third month
of gestation, until the bone marrow is formed in the seventh month and takes
over erythrocyte production exclusively.
ERYTHROCYTE
DIFFERENTIATION
Erythrocyte
differentiation takes place in 8 stages. It is the pathway through which an
erythrocyte matures from a haemocytoblast into a full-blown erythrocyte. The
first seven all take place within the bone marrow. After stage 7 the cell is
then released into the bloodstream as a reticulocyte, where it then matures 1-2
days later into an erythrocyte. The stages are as follows:
1.
Hemocytoblast, which is a pluripotent hematopoietic stem cell
2. Common
myeloid progenitor, a multipotent stem cell
3. Unipotent
stem cell
4.
Pronormoblast
5.
Basophilic normoblast also called an erythroblast.
6.
Polychromatophilic normoblast
7.
Orthochromatic normoblast
8.
Reticulocyte
Erythrocytes
are derived in the red bone marrow from pluripotent stem cells that give rise
to all types of blood cells. Myeloid stem cells are partially differentiated
cells that give rise to erythrocytes and several other types of blood cells.
Nucleated
erythroblasts are committed to becoming mature erythrocytes. These cells
extrude their nucleus and organelles, making more room for heamoglobin.
Reticulocytes are immature red blood cells that contain organelle remnants.
Mature erythrocytes are released into the capillaries. The pictures in this
link and here show the steps of differentiation.
DISTINCT
CHARACTERISTICS OF ERYTHROCYTES DURING ERYTHROPOIESIS
These
characteristics can be seen during erythrocyte maturation:
• The size
of the cell decreases
• The
cytoplasm volume increases
• Initially,
there is a nucleus and as the cell matures the size of the nucleus decreases
until it vanishes with the condensation of the chromatin material.
Functions of
Red Blood Cells
Apart from
carrying oxygen, which is the main function of red blood cell, it can also
conduct the following functions.
1. Release
the enzyme carbonic anhydrase which allows water in the blood to carry carbon
dioxide to the lungs where it is expelled.
2. Control
the pH of the blood by acting as an acid-base buffer.
Shape and
Size of a Red Blood Cell
A red blood
cell is a biconcave disc. Simply it is a round ball that is squeezed from two
opposite ends to appear, widest at the sides and narrowest in the middle.
A red blood
cell measures about 6 to 8 micrometers in diameter (average = 7.8 um) with an
average thickness of 2 micrometers (2.5 um at the thickest point and less than
1um at the center). Although a red blood cell is wider than some capillaries,
its flexibility allows it to become distorted as it squeezes through narrow
passages and then restores to its
original shape.
Quantity of
Red Blood Cells in the Human Body
The average
male adult has about 5 million red blood cells per cubic millimeter of blood,
while the average female adult has about 4.5 millionred blood cells per cubic
milliliter of blood. This may vary by about 300,000 to 500,000 red blood cells.
The number of red blood cells may vary depending on geographical location – a
person who lives in high altitudes will have more red blood cells.
Structure of
Red Blood Cells
Red blood
cells have an unusual structure compared to other cells in the human body. It
lacks a nucleus, mitochondria or endoplasmic reticulum. However enzymes within
the red blood cells allow it to produce small amounts of energy (ATP from
glucose). The most important part of a red blood cell is haemoglobin, which is
essentially the functional component of the cell.
Haemoglobin
Structure
Haemoglobin
is the molecule that is responsible for the oxygen carrying capacity of a red
blood cell. It also gives these cells a red colour and is a combination of
haeme and globin. Haeme is formed when succinyl-CoA binds with glycine to form
a pyrrole molecule. Four of these pyrrole molecules combine to form
protoporphyrin IX which binds with iron to form the haeme molecule. Globin is a
long polypeptide chain.
When a haeme
molecule and globin molecule combine, it forms a haemoglobin chain. There may
be slight variations in the haemoglobin chains designated as alpha, beta, gamma
and delta chains. Four of these chains need to combine to form the final
haemoglobin molecule and the most common combination in the human body, termed
haemoglobin A, is made up of two alpha and two beta chains.
Each iron
molecule can bind with one oxygen molecule, which contains two oxygen atoms.
Since each haemoglobin chain has one iron atom and each haemoglobin molecule
has 4 chains and therefore 4 iron molecule,s each haemoglobin molecule can
carry 8 oxygen atoms.
Every 100
milliters of blood, which contains various blood components, has about about 15
grams of haemoglobin.
REGULATION
OF ERYTHROPOIESIS
Thinking
logically you might suspect that because the primary function of erythrocytes
is to transport O2 (Oxygen) in the blood, the primary stimulus for erythrocyte
production is low O2 levels. You would be correct, but low O2 levels do not
stimulate erythropoiesis by acting directly on the bone marrow.
Instead, it
stimulates the kidneys to secrete the hormone erythropoietin into the blood,
and this hormone in a domino effect stimulates the bone marrow to produce
erythrocytes.
Erythropoietin
acts on derivatives of undifferentiated cells that have already been committed
to becoming red blood cells (RBC’s), stimulating the proliferation and
maturation of these cells into mature RBCs.
This
increase in erythropoietic activity elevates the number of circulating RBCs,
thereby raising the O2 carrying capacity of the blood and restoring the
delivery of O2 to the body tissues to normal. Once the O2 level in the tissues
of the kidneys is brought back to normal, erythropoietin secretion is turned
down until it is needed again. This is an example of a negative feedback
mechanism.
CONCLUSION
Having
mentioned all this. A normal red blood cell lives for about 120 days. It takes
about two days for the body to manufacture each red blood cell, and about two
million are turned out every second. Production of new red blood cells occurs
in the bone marrow.The main job of red blood cells is to carry oxygen from the
lungs to cells throughout the body. Red blood cells aid in the removal of
carbon dioxide, which is a waste product of several of the body's chemical
processes. The body must produce additional red blood cells because they
eventually break down and cannot perform their functions. Cells in the spleen,
liver and bone marrow eliminate useless red blood cells.
It takes
RBC`s 7 days to mature..However they DO NOT reach their full size until about 4
weeks(30days)....If Hijamah is adminstered before these cells reach their full
maturation stage...Then there is every possibility that these too would pass
through the semi permeable walls of the capillary bed along with the morbid
matter thus rendering the patient weak rather than having any positive
therapeutic benefit.
It is
absolutely imperative that the patient should be allowed sufficient recovery
time before they are brought back for their next remedial session.
The benefit
of such precautionary measures will yield in much greater results inshaAllah
