The goal of this study was to determine whether in vivo X irradiation induces nontargeted effects, such as delayed effects and bystander effects in ICR mouse lymphocytes. We first examined the generation of DNA double-strand breaks (DSBs) in lymphocytes, isolated from ICR mice exposed to 1 Gy X irradiation, by enumeration of p53 binding protein 1 (53BP1) foci, and observed that the number of 53BP1 foci reached their maximum 3 days postirradiation and decreased to background level 30 days postirradiation. However, the number of 53BP1 foci was significantly increased in lymphocytes isolated from ICR mice 90-365 days postirradiation. This result indicates that in vivo X irradiation induced delayed DSBs in ICR mouse lymphocytes. We next counted the number of 53BP1 foci in lymphocytes isolated from sham-irradiated ICR mice that had been co-cultured with lymphocytes isolated from 1 Gy X-irradiated ICR mice, and observed a significant increase in the number of 53BP1 foci 1-7 days postirradiation. This result indicates that in vivo X irradiation induced bystander effects in ICR mouse lymphocytes. These findings suggest that in vivo X irradiation induces early and delayed nontargeted effects in ICR mouse lymphocytes.

Objective: To illustrate the role of dehydrocorydaline (DHC) in chronic constriction injury (CCI)-induced neuropathic pain and the underlying mechanism.
Methods: C57BL/6J mice were randomly divided into 3 groups by using a random number table, including sham group (sham operation), CCI group [intrathecal injection of 10% dimethyl sulfoxide (DMSO)], and CCI+DHC group (intrathecal injection of DHC), 8 mice in each group. A CCI mouse model was conducted to induce neuropathic pain through ligating the right common sciatic nerve.
Dendritic pathology and overexpression of MAP2 in Purkinje cells from mice inoculated with rabies virus.

The effect of rabies virus infection on dendritic morphology and on the expression of the MAP2 protein in Purkinje cells in the cerebellum of mice was studied. ICR mice were inoculated with rabies virus, and six days later, the mice were sacrificed, the cerebellum was removed and processed for Golgi-Cox staining or MAP2 immunohistochemistry. Infection with rabies virus altered the dendritic pattern of Purkinje cells ranged from moderate changes to accentuated retraction in the dendritic tree of some Purkinje cells.

This study aims to reveal the effects and mechanisms of different fractions of Polygonati Rhizoma on the reproductive dysfunction in male mice with kidney essence deficiency due to excess of sexual intercourse. Fifty male ICR mice with good sexual function were selected and randomized into normal(NC), model(MC), n-butanol fraction of Polygonati Rhizoma(0.4 g·kg~(-1), HJCT), remaining fraction of Polygonati Rhizoma(0.
