RESUMEN
OBJECTIVE:To explore the effects of Haikangling Mixture on immunological function in immunosuppressed mice induced by cyclophosphamide. METHODS: Mice were given Haikangling Mixture intragastrically for 14d, and the level of hemolysin was determined by sheep erythrocyte (SRBC) immunization to exploer the influence of Haikangling on humoral immunity in mice; splenic lymphocytes were measured by MTT to observe the influence on cell immunity; the clearance of macrophage were measured by carbon particle clearance method to explore the influence on non-specificity immunity. RESULTS: The level of hemolysin, the cell reproductive activity, splenic lymphocytes and the phagotrophy of mononuclear macrophage were improved obviously by Haikangling Mixture in immunosuppressed mice induced by cyclophosphamide. CONCLUSION: Haikangling Mixture can enhance the immunological function in immunosuppressed mice induced by cyclophosphamide.
RESUMEN
This experiment showed that Yiqipingchuan Pills possessed obvious treatment action of cough and asthma,and expectorant action.It could cause a striking increase in the immunity-organ weight and carbon-particle clearance of hypoimmune mice.It was also found that these pills could make the con- centration of serum-hydrocortisone rise and the Vitamin C content in suprarene lower remarkably.

RESUMEN
Rabbit's brain phospholipids (RBP) 100~200 mg ?kg-1 ip or sc showed anti-inflammatory action on four kind of acute inflammatory animal models. Cephalin and Lecithin were the effective component of antiin-flammatory action on the acute inflammatory animal model. But RBP did not show antiinflam-matory action on the chronic proliferative inflammatory model. RBP increased blood carbon particle clearance, perfaneal macrophage phagocytosis and enhanced lymphocyte proliferation,hemolysin antibody in normal and immunode-pression animal. RBP increased the cGMP content in the liver tissue of immunodepression animal, 0. 1~1 mg ?L-1 RBP promoted proliferation but 100 mg ?L-1 RBP inhibited proliferation induced by PHA in vitro on human lymphocyte.
RESUMEN
Wistar rats pretreated with BCG, dexamethasone or carbon particles respectively were inoculated with P. yoelii sporozoites via caudal vein. 42 hours after inoculation, the animals were killed to examine the effects of these 3 agents on the invasion of sporozoites and the development of exoerythrocytic forms (EEF) .It was found that in the carbon group about 30% of the kupffer cells contained the particles, and the density of EEF apparently decreased as compared with that of the control. In the BCG group, a dosage of 6 ? 107 units also caused a marked decrease of EEF density, an,d the parasites were smaller with a higher rate of degenerated forms as compared with those of the control, In the dexamethasone group, however, the EEF density increased markedly up to the level 1.5-2 times higher than that of the control. In addition the EEF were larger and more numerous with vacuoles and some lobulated. The mechanism of these facts were discussed.
