7. Comparison with
other commercial products
Comparisons of GCP
with shark cartilage (powder or liquid) and other isoflavone extracts
for their angiogenesis effects.
Materials:
GCP
Product A (Containing 40% isoflavone)
Product B (Containing 40% isoflavone aglycones)
Powder shart cartilage (Containing 60% shark cartilage)
Liquid shark cartilage
Method: CAM
Preparation for samples: Dissolved in
PBS or in DMSO by 100mg/ml concentration, and diluted with PBS, the
final DMSO concentration is less than 1%, 0.2ml of samples was added
in the eggs. The liquid shark cartilage was added by original liquid.
Each sample was added into 3 eggs.
Result:
(Table 9 and Fig. 15)

Comparison of GCP
with other commercial products on inhibition of vessels in tumor
located areas
Method: Tumor-bearing
mice model transplanted with S-180 sarcoma. GCP, Product A, Product B
were dissolved in tap water by 10% and administrated, p.o. by
original liquid of 0.35ml/day/ mouse for two weeks.
Result: The
vessels in tumor located area clearly were found in untreated control.
Vessels almost disappeared in GCP-treated mice while other commercial
products and shark cartilage did not show such effects (Fig. 16).

Comparison of GCP
with other commercial products on inhibition of tumor growth
Method: Tumor-bearing
mice model transplanted with S-180 sarcoma
Administration: GCP, Product A, Product B: Dissolved in tap water by
10% and administrated, p.o. by the dosage of 0.35ml /day/mouse.
Period: Two weeks.
Observation: Tumor
growth curve, tumor weight.
Results: GCP significantly inhibited the tumor growth of S-180, while
shark cartilage, Product A or B did not show this inhibitory effect.
