A sample of 30 mice aged 8-12 weeks, weighted 20-30 grams, and exposed to Salmonella typhimu¬rium was selected for this study randomly. Sampele was divided into 5 groups and received: (1) aquadest (control). (2) bajakah stem extract dose 25 mb/kgBW, (3) bajakah stem extract dose 50 mg/kgBW, (4) bajakah stem extract dose 100 mg/kgBW. And (5) 30 mg/kgBW modulator drugs. The dependent variable was Bajakah stem extract. The independent variable was leukocytes. The data were analyzed by ANOVA test.
Results: Bajakah stem extract dose 100 mg/kgBW reduced leukocytes in mice exposed to Salmonella typhimurium (p<0.001).
Conclusion: Bajakah stem extract dose 100 mg/kgBW reduced leukocytes in mice exposed to Salmonella tyhimurium.
