When something is made by human that is fully controlled by human
due to full knowledge about what has been made. So who knows about human
anatomical structures and function of human body??? Main point is we are the
peoples or human being, we never create each others. We have knowledge about
human being but not full knowledge in every part of human body that is why many
diseases are not curable just only controllable e.g. some autoimmune diseases ,DM etc. human have
powerful knowledge than any other creations in the world that is why we human
can protect our self from other harmful creations
like pathogens who attack human although human have Defenders inside human body
like very strong `immunity` as a human body
defender . Very easy example is everybody knows about windows 8 Defender as it
defends windows from any kind of viruses or any kind of harm full entry that
may crash the windows. Human War against
Diseases always in Medicine. Human cannot create a life so they have lack of
knowledge about that is why many diseases are controllable not curable. Once we
human have full knowledge about, we control fully or protect fully from Diseases.
Some keywords should be known like Immunity and functions of it.....
What is the Immunity? it is the capability of human body to protect
or resist from pathogenic microbes or viruses that is harmful from entering to
our body is defined as Immunity. Until now it is not clear because there is a question;
who have capability power to resist human body? Is it immunity or someone else?
Answer is the composition of the Immunity, now named immunity can be a group name;
this group is made by members so the members are the responsible for protecting
human body. Yet it needs to be answered the question of name of the members. Yet
it does ask some questions like where they are come from or born? Do they come
from same area? Have all have same characters or functions?
Very famous name are T-cell, B-cell, Macrophage and Neutrophil.
Main functions are same as resist body through different way; every member has
their own way not the same way. it should be noted that all members work together
; they call each other when needed and produce the Anti-pathogenic substance
called "Antibody" that kill the diseases or pathogens but it needs
time to produce the Antibody average 7 to 10 days time differ from different pathogens.
Now it could be said that the antibody is the human body defender from inside. Now
name of the members can be modified as immune cells. They come to the blood
circulation in order to go to the infected part of body and kill the pathogens.
Blood is only the media for transferring immune cells or antibody to any part
of body. the immunity is classified into ...1. Innate immunity, 2. Adaptive immunity
is classified into natural immunity and artificial immunity; natural immunity
is divided into passive and active immunity and also artificial immunity is
divided into active and passive immunity. To understand this classification
needs some basic knowledge about immunity. Any cells that destruct pathogens are
called immune cells. All immune cells are produced by Bone Marrow. What is Bone
Marrow? Simply it is bone of human body like humerous, femer and sternum
etc.human body have a lot of bones as source of immune cells .Most common
immune cells are white blood cells together called "Leucocytes". These
leucocytes are T-cells, B cells and Phagocyte cells e.g. macrophage, Neutrophil
and also mast cells, Eisonophil, Basophiles and dendrite cells. From these
immune cells some of them can divide into many own cells; as a colonization. But
others are unable to colonize into many cells. So here is the point is who are
able to divide, these are responsible for adaptive immunity. Now the question
is what adaptive means here is; condition where immune cells are specific and
specific to specific pathogens and produce memory immune cells for future challenge
to same pathogen that attacked first time. so immune cells those joined in this
condition is called adaptive immune cells (T-cells and B cells )as called
"Adaptive Immunity". Second point is what is the Natural Immunity? ;
unable to divide , no memory cells produced and remain same from the start and
join to fight against non specific pathogen
directly through producing toxic substances like hydrogen peroxide, Oxygen free
radicals’ and by recognition of MCH; tissue surface marker antigen as MCH. These
immune cells are Neutrophil, Macrophage, Basophil, mast cell and dendrite cell
. They initiate the first line defense from disease. In this
situation cells are called "innate immune cells as Innate Immunity. If require the activation of immune cells by
stimuli to fight, it is adaptive type. After being analyzed the information above,
the immunity can be considered as "Antibody”. Now the question is what is
the Natural Immunity? It is the sub type
of adaptive immunity, also it is divided into two part one is the passive
immunity e.g. maternal antibody is the antibody that cross placenta to fetus. Second
is what the active immunity is? It is the antibody that has been formed against
infection. What is the artificial immunity? This is the antibody that is readymade
like Vaccination; antibody from out site source but not from human body is
injected into human body is called "Artificial Antibody". Either it
is active or passive. Basic knowledge about immunity here is enough to
understand the Immunity.
Remember sometime antibody has been formed than it attacks
own body instead of pathogens is called "Auto-Immunity". bcz some pathogen
are more clever , pathogen make his body as a human body that is why antibody
attack own body, this condition is called Auto antibody or auto immunity. Anything
from outside human body enter into human body is called foreign body, not foreigner,
but it is called foreign body bcz if any student travel to a new country it is
called foreign student for that country. Now new topics about immunological
disease can be discussed.
45 years old
female patient complaining of pain over knee joints that is worse after activity,
in the back and nodules over dorsum of the both hands, Z like Thumbs deformities
etc. on knee examination there are crepitus and limitation of movement. No other
positive findings. Most probably this unlucky patient having both Osteoarthritis
and associated with Rheumatoid arthritis.
