Results and discussion

Results of examinations

Details on results:
In female CD-1 mice (30 mice/group) dosed intragastrically at 3 concentrations: 1000, 500, and 250 mg/kg/day Vanillin, and vehicle control
(1% methylcellulose) for 5 consecutive days; control untreated group, positive control group: host resistance to Listeria monocytogenes;
Anti-sheep red blood cell (SRBC) plaque-forming cell (PFC) assay: specific cellular activity, and total speen activity;
no significant difference in treated group by Vanillin from untreated control group.
