ABSTRACT
AIM To study the pharmacodynamics of Baijin Granules [Mallotus apelta (lour.) Muell.Arg.,Smilax china L.],Zhuang medicine,on model rats with sequelae of pelvic inflammatory disease.METHODS The rat model for sequelae of pelvic inflammatory disease was built with mixed bacteria (Escherichia coli and Staphylococcus aureus) and mechanical injury.Subsequently,the rats were randomly divided into eight groups,including model,Baijin Granules low-,middle-,high-dose,positive control (dexamethasone and Huahong Granules),blank control and sham operation groups,with ten rats in each group.After 14 days of successive administration,the hemorheology and blood routine in rats' abdominal aorta were measured by collecting blood in 24 hours of last administration.The pathological morphology of uterine tissue was observed.RESULTS The hemorheology indexes,WBC count and neutrophil percentage were significantly decreased in the model rats,and the pathological morphology of uterine tissue was markedly improved.CONCLUSION Baijin Granules have good therapeutic effects on sequelae of pelvic inflammatory disease in rats.
ABSTRACT
The effects of Dangguibuxue Tang (DBT) on growth performance and immunity response in immunosuppressed broiler chicks were investigated in this study. 240 one-d-old broiler chicks (DaHeng S01) were randomly divided into 4 groups, 2.0% DBT-treatment (A), 0.5% DBT-treatment (B), cyclophosphamide-control (C), and control group (D). From 4 d to 7 d of age, chicks in group A, B and C were given cyclophosphamide (CY) at a dosage of 100mg/kg body weight (BW) daily by intraperitoneal injection to induce immunosuppression. Chicks in group D were given an equal volume of physiological saline daily by intraperitoneal injection and considered normal chicks. Groups A and B were supplemented with 2.0% or 0.5% of DBT in the drinking water from 8 d to 42 d of age. Groups C and D did not receive any additional medication. The results revealed that chicks from group B had lower feed:gain rate (FGR), lower total mortality, higher immunity organ indexes, higher levels of Newcastle disease (ND) antibody and infectious bursal disease (IBD) antibody, higher interleukin-2 and interleukin-6 levels, and greater lymphocyte proliferative responses to concanavalin A (ConA) during the experiment than those from group C. However, no significant difference in the immunity status in the two levels of DBT-treatment was observed. These results indicate that supplementation of 0.5% of DBT can improve both cellular immunity and humoral immunity in immunosuppressed broiler chicks.
