简要总结

The study is based on the hypothesis that consumption of cranberry juice products results in the production of metabolites in the urine that have anti-adhesive properties on bacteria. A crossover study using 12 healthy women will be given different cranberry products or water as a control and their urine will be analyzed for anti-adhesive effects and compared to the properties of the urine. Cranberry juice will also be evaluated for its effect on vaginal microflora.

详细描述

Hypothesis: Metabolites in cranberry juice, have anti-adhesive properties for uropathogenic bacteria but they do not disturb the normal vaginal flora.

Study design and assays:

A crossover study design using 12 healthy women will be conducted for 50 days. The anti-adhesive properties of the urine will be determined using uropathogens and changes in the vaginal microflora will be evaluated.

Participants:

The subjects will be healthy premenopausal women aged 19-45, who have no history of chronic urinary tract infection or have had a urinary tract infection in the past 12 months, and are currently not taking antibiotics or any supplements to prevent UTI, including cranberry juice. The subjects must not have urinary tract abnormalities, requiring catheterization for micturition, be pregnant, or diabetic or have allergies to berry juices. Each test phase is 1 week (7 days) and the following protocol will be followed:
