A double-blind randomized trial comparing lidocaine spray and placebo spray anesthesia prior to cervical laminaria insertion.

Objective: To compare pain during laminaria insertion after lidocaine spray versus placebo spray anesthesia in women about to undergo a surgical abortion procedure.

Study Design: A double blind, randomized, placebo-controlled trial of women at 12-24 weeks gestation one day prior to surgical uterine evacuation procedure. Participants received lidocaine 10% or placebo (saline 0.

CD4+CXCR4highCD69+ T cells accumulate in lung adenocarcinoma.

The chemokine receptor CXCR4 is involved in the growth and metastasis of tumor cells. However, the expression of its ligand, the chemokine CXCL12, in tumors and its role in regulating the accumulation of immune cells within the tumors is not clear. Using ELISA and immunohistochemistry we found that CXCL12 is expressed in the majority of nonsmall cell lung cancer tissue sections obtained from stage IA to IIB nonsmall cell lung cancer patients undergoing operation.
