It is a class of water-soluble alkaline glycopeptide antibiotics.It mainly inhibits the incorporation of thymidine into DNA, binds to DNA to destroy and decompose it, and acts on the S phase of the proliferating cell cycle. It can be used for resistance screening and induction of pulmonary fibrosis models.


Examples of using this product(for reference only):

In Vivo:

Mice(male ICR mice, aged 8–12 weeks,weighting 18–22 g;):

The pulmonary fibrosis model in mice was prepared by atomization inhalation of bleomycin. When the mice were awake, they were put into a transparent plexiglass box with 30 cm×30 cm×20 cm connected with the atomizer and atomized 5 g/L (50%) bleomycin diluent was sprayed into the box through the atomizer tube. Three to four mice were put in the box at a time and exposed to bleomycin for a total of 3 hours and 15 minutes of bleomycin inhalation separated by 7 sessions of 5 minutes of rest. In the control group, mice received saline as a replacement for bleomycin inhalation [4, 18]. On the second day after modeling, all mice except those in the control group and model group were orally treated with saline, and the mice in the positive group and treatment group were continuously administrated with prednisone acetate (at a dose of 0.0064 mg/g) or Bufei decoction (at a dose of 1.235 mg/g) for 4 weeks.

Abstract:

Objective:This study aimed to investigate the mechanistic action and therapeutic effects of Bufei decoction on idiopathic pulmonary fibrosis (IPF) after inhalation of bleomycin.

Methods:Pulmonary fibrosis model in mice was prepared by atomization inhalation of bleomycin. Then, the mice were randomly divided into five groups (control group, model group, positive group, and treatment group) and administrated the drugs for 4 weeks. H&E and Masson's staining of lung tissues were used to observe the morphological changes and deposition of fibers, and the degree of fibrosis was evaluated by hydroxyproline content. The expression and activation of NF-κB were determined by western blotting and immunohistochemistry. The infiltration of macrophages was detected by immunostaining of CD45 and F4/80 in lung tissues.

Results:In mouse IPF, Bufei decoction alleviated the pathological changes and the deposition of fibrosis by decreasing the content of hydroxyproline of lung tissues. The antipulmonary fibrosis might rely on the effects of preventing the infiltration of inflammatory cells and inhibiting the expression and activation of NF-κB in lung tissue.Conclusion: Bufei decoction improved the process of pulmonary fibrosis by regulating the activation and expression of the NF-κB signal transduction pathway, which provided a therapeutic option for IPF patients.
