PREVENTION
lS BETTERTHAN
CURE (2):
PREVENT RESPIRATORY SYSTEM INFECTIONS
IN
WINTER/SPRING
SARS
is
dreadful but
is
just
one of
the
many respiratory infections. lnfections
are:
sinusitis, tonsilitis,
pharyngitis, bronchitis, chest
infection,
flu
and
tuberculosis,
etc.
Other respiratory diseases are
allergy,
trauma
(e.g., adult respiratory distress syndrome or ARDS), cancer, e.9., nose or nasopharyngeal, throat, voice box
and lung cancers. lnfections are
usually
due
to
bacteria, virus
(e.9.,
the corona virus of SARS),
rickettsia,
mycoplasma, fungus,
etc.
Apart
from
reflex sneezing and coughing, our comprehensive respiratory defense
system consists of the vigorous action of cilia on the surface of
cell
lining to sweep away unwanted material
to
be spitted
out as
phlegm.
With
excessive exposure
to
cold or
tobacco
smoke,
these
cilia
are
inactivated.
"Complements" also
abound.
These proteins suppress micro-organisms
by
enzymatic actions:
lysozyme,
a1-antitrypsin and secretory immuno-globulin
A
(SlgA).
However,
prolonged smoking would reduce
such
secretions. Macrophages
also
engulf micro-organisms just
like
amoebas.
Rarely,
too
profound
defense mecha-
nism may start
to
destroy even normal
tissues causing
multi-system/organ
failure
(MSOF) and
death.
Treat
acute infections
promptly.
Better
still,
prevent infections by regular exercises, keeping warm;
if
required,
vaccinate against
flu.
Paradoxically,
deliberate and
programmed
cold
exposure, e.9., cold
water
bath for
fit
subjects would enhance body resistance.
