In vivo effect of catechin on H. pylori colonization
| Expt and group | Bacterial count (log CFU/stomach)a | Clearance rateb (%) |
|---|---|---|
| A | ||
| Control | 5.54 ± 0.59 | 0/9 (0) |
| 0.5% Catechin diet | 4.38 ± 0.51c | 1/10 (10) |
| 1.0% Catechin diet | 4.89 ± 0.59 | 1/9 (11) |
| 2.0% Catechin diet | 5.05 ± 0.73 | 1/9 (11) |
| B | ||
| Control | 5.12 ± 0.29 | 0/11 (0) |
| 1.0% Catechin diet | 4.77 ± 0.47 | 1/10 (10) |
| 1.0% Catechin diet + 0.5% catechin water | 5.04 ± 0.26 | 4/11 (36) |
a
The bacterial counts of each group (excluding the gerbils in which the bacteria had been eradicated) were added, and the average was calculated. The results are expressed as the mean ± the standard deviation. A one-way ANOVA and Scheffe’s test were used for statistical analysis.
b
The clearance rate shows the number of gerbils in which H. pylori was not detected in the gastric mucosa.
c
Statistically significant reduction (P < 0.01) compared with the control.
