Clinical efficacy of ambroxol intravenous and budesonide atomizing inhalation combined with cefodizime on infantile pneumonia / 中国生化药物杂志

Objective To investigate the clinical efficacy of ambroxol intravenous and budesonide atomizing inhalation combined with cefodizime on infantile pneumonia and its effects of serum PCT, IL -6 levels and related immune factors.Methods 95 children with pneumonia from May 2013 to October 2015 in Sanya Hospital of Traditional Chinese Medicine were collected and randomly divided into control group(n=47) and experiment group (n=48), two groups were treated by clinical routine treatment, such as antipyretic, anti-inflammatory, strengthen nutrition in children, and control group were added with ambroxol, iv, qd; experiment group were added cefodizime on the basis of control group, the course was one week.Clinical efficacy,serum PCT, IL -6 levels, immune factors and adverse reactions were observed and compared.Results The serum PCT and IL -6 levels of experiment group were lower than control group post-treatment, and CD4 +, CD4 +/CD8 +levels were higher than control group, CD8 +level was lower than control group, the differences were all significant (P<0.05).The effective rate of experiment group was 93.75%, higher than 80.85% of control group(P<0.05).Incidence of adverse reactions between two groups had no statistical difference.Conclusion Ambroxol intravenous and budesonide atomizing inhalation combine with cefodizime in treatment of infantile pneumonia has better clinical efficacy, could effectively reduce the serum PCT and IL-6 levels, effectively improve the clinical symptoms.

In Vivo and in Vitro Antibacterial Activities of Cefodizime Sodium / 中国药房

OBJECTIVE: To evaluate the in vitro and in vivo antibacterial activities of cefodizime from both home and abroad. METHODS: The minimal inhibitory concentrations (MICs) of domestic and imported cefodizime, cefotaxime sodium against 300 clinical isolates of bacteria were tested by standard agar dilution method and the test tube dilution method. The in vivo antibacterial activities of cefodizime were determined in mice with experimental systemic infection caused by E.coli, K. pneumoniae and S.aureus. The values of ED50 were calculated by Bliss method. RESULTS: Both domestic and imported cefodizime had remarkable potency against majority gram- negative bacteria and gram- positive bacteria, including pneumococcus and beta streptococcus, and the MIC90 of cefodizime stood at 0.012～1.0?g?mL-1; and they showed medium grade antibacterial activity against bacillus cloacae, bacillus aerogenes and serratia but mild effects on MSSA and S.epidermidis, and the MIC50 stood at 4?g?mL-1. In this trial, bacillus aeruginosus, acinetobacter, enterococcus and MRSA showed resistance against the domestic and imported cefodizime. The in vivo antibacterial activities of domestic and imported cefodizime were similar and remarkable in mice infected with E.coli, K.pneumoniae and S.aureus. CONCLUSION: Domestic and imported cefodizime had excellent and similar antibacterial activity.

Effect of Insulin Injection on the Stability of Cefodizime Sodium for Injection / 中国药房

OBJECTIVE: To study the effect of insulin injection on the stability of cefodizime sodium for injection in 5% glucose injection.METHODS: The appearance and the pH value of the mixed solution in 12 h were monitored and the content of cefodizime sodium in the mixed solution was determined by HPLC.RESULTS: There were no evident changes for the mixture in appearance,pH value and the content of cefodizime sodium within 12 h at room temperature.CONCLUSION: Insulin injection has no effect on the stability of cefodizime sodium within 12 h at room temperature.

Effects of Cefodizime on Phagocytosis of COS-1 Ccells

PURPOSE: Cefodizime is a new third-generation cephalosporin which has a structure and immunomodutation properties similar to cefotaxime. Various studies on cefodizime have demonstrated the direct eradication of bacteria in cooperation with the host defense mechanism, particularly with phagocytosis. We evaluated the effects of cefodizime on the phagocytosis of COS-1 cells transfected with FcgammaRI/gammagamma or FcgammaRIIA cDNA. METHODS: Phagocytosis was measured using the in vitro COS-1 cell modeling system according to Schreiber's method. COS-1 cells, which lack endogenoous Fcgammareceptors but have phagocytic potential, were transfected with either FcgammaRI/gammagammaor FcgammaRIIA cDNA. COS-1 cells, as target cells, were treated with antibiotics for 1 or 24 hours and incubated for 30 min with IgG coated sheep RBCs. Adhered IgG coated sheep RBCs were removed after brief exposure to hypotonic phosphate buffered saline. Phagocytosis index (PI) was calculated as the number of ingested RBCs per 100 phagocytic cells after wright-Giemsa staining. RESULTS: COS-1 cells tranfected with FcgammaR (either FcgammaRI/gammagamma or FcgammaRIIA cDNA) showed the phagocytic activity against IgG coated sheep RBC, while untransfected COS-1 cells did not. After treatment with cefodizime, phagocytic activity of FcgammaRI/gammagammacDNA transfected COS-1 cells was significantly increased, while that of FcgammaRIIA cDNA transfected COS-1 cells did not. Marked enhancement of phagocytosis of COS-1 cells was observed after treatment with cefodizime, but was not observed with ceftriaxone or moxalactam. CONCLUSION: Cefodizime showed marked enhancement of phagocytic activity of FcgammaR transfected COS-1 cells. FcgammaRI seems to play an important role in the enhancement of phagocytosis. Further studies will be required.

Effects of cefodizime on the T-lymphocyte subsets of peripheral blood in mice with immunological liver injury / 西安交通大学学报(医学版)

Objective To study the regulatory effect of cefodizime on the T-lymphocyte subsets of peripheral blood in mice with immunological liver injury.Methods The mouse model of immunological liver injury was induced by Bacillus Calmette Guerin and Lipoposaccharide.The study was conducted by using completely random design.The mice with immunological liver injury were divided into thymosin group,cefodizime high-,medium-,low-dose groups,ceftriaxone group and the normal saline group.The six groups were continuously administered agents respectively for 7 days,and T-lymphocyte subsets of peripheral blood in mice were determined and contrasted with those of the normal mice treated with normal saline on the 7th day.Flow cytomytry was used to determine the effects of cefodizime on T-lymphocyte subsets of peripheral blood in mice by using immuno-fluorescence technique.Results The immunological liver injury mice were deficient because their CD3+(%),CD4+(%),CD8+(%) and the ratio of CD4+CD8+ were lower than those of the normal mice.Cefodizime effectively increased CD3+(%),CD4+(%) and the ratio of CD4+CD8+ of the mice with immunological liver injury.Conclusion Cefodizime effectively improves the immune function of the host by regulating the balance between CD4+ cell and CD8+ cell.
