Objective Different models were used to evaluate the immunomodulatory effect and anti-stress effect of Haima Bushen Pills. Methods The healthy Kunming mice were randomly divided into control group, model group, lentinan group (100 mg/kg), Guilingji group (0.24 g/kg) and Haima Bushen Pills group (0.55, 1.10 and 2.20 g/kg). The mice were ig given relevant drugs once a day for 14 days. ① Immunosuppressive model of mice was induced by cyclophosphamide hydrochloride injection. Indian ink of 25% was iv at the end of administration. Clearance index (κ) and phagocytic index (α) were calculated. Liver index, spleen index and thymus index of mice were observed. ② Immunosuppressive model of mice was induced by injection of cyclophosphamide hydrochloride, and sensitized by 0.3 mL of IP 5% chicken erythrocyte suspension. Serum hemolysin production was observed in each group. ③ On the 8th to 10th day of administration, except the control group, the remaining groups began ip cyclophosphamide 80 mg/kg for 3 consecutive days. The orbital vein blood was collected on the 14th day of administration, and the number of white blood cells and the contents of immunoglobulin IgG, IgM and IgA were measured. ④ SD rats were randomly divided into control group, model group, isosorbide mononitrate tablets 20 mg/kg, Guilingji 0.12 g/kg and low, medium and high dose groups (0.28, 0.56, 1.12 g/kg) of Hippocampus Kidney-tonifying Pills. The effects of Hippocampus Kidney-tonifying Pills on the levels of serum urea nitrogen (BUN), lactic acid (LD) and hepatic glycogen in exercise-fatigue rats were observed once a day for 14 days. ⑤ Healthy Kunming mice were randomly divided into control group, model group, isosorbide mononitrate tablet (40 mg/kg), Guilingji (0.24 g/kg) group and Hippocampus Kidney-tonifying Pills (0.55, 1.1, 2.2 g/kg) group. The mice were given Ig once a day for 5 days. One hour after the last administration, the mice were injected with isoprenaline to induce hypoxia. The mice were placed in sealed bottles for observation of survival time. Results Compared with model group, 2.2 g/kg of Haima Bushen Pills significantly increased α and κ (P<0.05 and 0.01), 1.1 and 2.2 g/kg of Haima Bushen Pills significantly increased spleen and thymus coefficient (P<0.05 and 0.01), and each dose of Haima Bushen Pills significantly increased serum hemolysin production (P<0.05 and 0.01); 2.2 g/kg of Haima Bushen Pills significantly increased the number of white blood cells and the IgG, IgM and IgA (P<0.05); the dosage of Haima Bushen Pills (0.56, 1.12 g/kg) significantly prolonged the exhaustive swimming time of rats (P<0.05, 0.01); the dosage of 1.12 g/kg could significantly reduce the contents of BUN and LD in serum and the consumption of hepatic glycogen (P<0.05, 0.01); the dosage of Haima Bushen Pills (1.1, 2.2 g/kg) could significantly prolong the hypoxic survival time of mice (P<0.05, 0.01). Conclusion Haima Bushen Pills has obvious immune enhancement and anti - stress effect.
