Allergic identification for ginkgo kernel protein in guinea pigs

Area of Science:

• Immunology
• Toxicology
• Food Science

Background:

• Ginkgo biloba L. consumption is linked to potential allergic reactions.
• Understanding the allergenic capacity of ginkgo kernel protein is crucial for food safety.

Purpose of the Study:

• To investigate the allergenic potential of ginkgo kernel protein using a guinea pig allergy model.
• To evaluate the immune response and physiological changes associated with ginkgo kernel protein exposure.

Main Methods:

• Guinea pigs were sensitized orally and intraperitoneally with ginkgo kernel protein.
• Allergy grades, immunoglobulin levels (G and E), footpad swelling, and passive cutaneous allergy tests were assessed.
• Histopathological examination of lungs and intestines was performed.

Main Results:

• A 100% allergy rate and an average allergy grade of four were observed in sensitized guinea pigs.
• Significantly elevated immunoglobulin G and E levels were detected compared to controls.
• Distinct footpad swelling, positive passive cutaneous allergy test, and inflammatory changes in the lungs and intestines were noted.

Conclusions:

• Ginkgo kernel protein demonstrates significant allergenic capacity.
• The findings suggest that ginkgo kernel protein can induce a robust allergic response in a mammalian model.
• Further research is warranted to identify specific allergens and establish safe consumption limits.
