Protective effect of Poly gala tenui folia willd on genetic damage and enhancement of lymphocyte function induced by cyclophosphamide in mice / 吉林大学学报(医学版)

ABSTRACT

Objective To study the effect of anti-mutation of Chinese medicinal herb Poly gala tenui folia willd on T lymphocyte proliferation in spleen. Methods The micronucleus test of mouse bone marrow cell (MNT) thirty mice were divided into six groups (n = 5) , negative control (NS) , cyclophosphamide group (CP 3. 0 mg ? kg-1) , Poly gala tenui folia willd antimutagenesis groups (Polygala tenui folia willd with dosage of 0.5, 1.0. 2.0, 4.0 g ? kg-1 + CP 30 mg ? kg-1 ). The improved method was used to detect the micro-nuclei frequency. Lymphocyte transformation test twenty-four mice were divided into four groups (n = 6), saline control , CP control (3.0 mg ? kg-1), Polygala tenui folia willd (2.0 g ? kg-1), Polygala tenui folia willd + CP (2. 0 g ? kg-1 Polygala tenuifolia willd + CP 30 mg ? kg- ) group. MTT assay was used to calculate the stimulation index (SI). Results The micro-nuclei frequency was significant difference between Poly gala tenui folia willd antimutagenesis groups and CP groups (P
