The schematic diagram of the experimental design for NMBA injection and RPS administration.

Abstract

<p><b>A</b>. A schematic representation of experimental protocol. The empty arrows indicate subcutaneous injection of saline. The solid arrows indicate subcutaneous injection of NMBA. The shaded area represents oral RPS administration. <b>B</b>. The chemical formula of RPS. The letter “R” indicates that different functional groups can be at that position, resulting in different types of RPS with various molecular structures.</p
