Materials
and Methods
Cases under observation:
Fifty cases over the age of 55 were chosen, nineteen of
which were in their late middle-ages (55-59) and thirty-one
of which were over the age of 60. Among the elderly, ten
cases were between the ages of 65 and 69, while six of
the cases were over 70. The eldest was 77. Of the fifty
cases, twenty-three were male and twenty-seven were female.
The average age was 62. No organic diseases existed in
any these cases.
Dosage and Method:
Subjects took Vital Cell daily for thirty days as a full
course of treatment.
Observation
Observed changes in rheological
properties of the blood: Venous blood was drawn
from each subject one day before initial administration
of Vital Cell and thirty days after. The blood was tested
for whole-blood viscosity, plasma-specific viscosity,
RBC electrophoresis, packed cell volume and blood sedimentation.
These tests were conducted at a constant
temperature of 25C. The instruments used were as follows:
XN-5 blood viscometer produced by the Shanghai Medical
University, XN-5 cell electrophoresis automatic indicator,
and a BME-1 biomedical data processing computer. The methods
applied were capillary determination, micro-square tube
and Wintober tube.
Observed changes in nail fold microcirculation: Two observations
were made of each case the day before administration and
thirty days after administration. The main objective was
to observe changes in nail fold capillary shape and microcirculatory
blood fluidity.
These observations were made through
a microscope on the nail fold of the third finger of the
left hand at a constant used. This optical machine is
produced by the Xuzhou Photo Instrument Factory in the
Jiangsu Province.
Results
Rheological properties of blood:
Post-administration observations were as follow: Whole-blood
specific viscosity was P<0.01 and the RBC electrophoresis
time was P<0.01. This showed a marked improvement in
the clustering quality of RBC following administration.
The plasma-specific viscosity ratio of P<0.05 showed
a marked improvement of viscous elements in the plasma
after administration. (See Table 6)
Observation of changes in nail
fold microcirculation: After Vital Cell was administered,
there was no significant change in morphological capillary,
but the microcirculatory blood fluidity was greatly improved.
Comparing the improvements in blood fluidity and the rate
of blood flow before and after administration, the value
of P is less than 0.01. (See Table 7)
