Objective To realize the relationship between substance P(SP) and abnormal gastrointestinal transit.Methods By radioimmunoassay, concentration of SP in sigmoid mucosa was determined in 12 healthy volunteers, 15 slow and 10 fast transit patients.Results The concentration was (27.68±15.42)μg/g,(24.07±5.76)μg/g and (28.61±18.34)μg/g,respectively.They had no statistical difference.Conclusion There was no relationship between concentration of SP in sigmoid mucosa and abnormal gastrointestinal transit.
