Preparation and Performance Study of Rapid Repair Epoxy Concrete for Bridge Deck Pavement.

With the rapid development of bridge construction, the service life of bridges and traffic volume continue to increase, leading to the gradual appearance of diseases such as potholes and cracks in bridge deck pavements under repeated external loads. These issues severely impact the safety and service life of bridges. The repair of bridge deck potholes and cracks is crucial for ensuring the integrity and safety of bridge structures.

Brain IL-1 beta was involved in reserpine-induced behavioral depression in rats.

Aim: To investigate the mechanism of brain interleukin-1 beta (IL-1 beta) in reserpine-induced behavioral depression in rats.

Methods: Porsult swim test was used in the measurement of depressive behavior and ELISA was used in measurement of brain IL-1 beta.

Results: Intraperitoneal injection of reserpine (0, 4, 6, and 8 mg/kg, ip) increased floating time in the Porsult swim test in a dose-and time-dependent manner in rats.
