Object of research: autopsy material of human stellate ganglia in the age of 45-59 years old. Purpose of research: to identify expression patterns of substance P (SP), met-enkephalin (met-ENK) and bombesin (Bom) in normal human stellate ganglia and after acute myocardial infarction (AMI). Methods of research: indirect immunohistochemical, histological, morphometrical, statistical. Equipment used: universal photomicroscope “Axiophot” (Zeiss), light microscope “Olympus”, automatic images system and computer processing data, automatic cryostat microtome “Jung” (Leika). The results and their novelty: for the first time a research of SP, met-ENK and Bom immunoreactivity distribution in normal human stellate ganglia and after acute myocardial infarction was conducted. It has been revealed that in normal human stellate ganglia heterogenic population of neurons and nerve fibers immunoreactive to SP, Met-ENK and Bom exists. Appearance of population of small neurons immunoreactive to SP, met-ENK and Bom is a pattern of AMI. Increase of SP, met-ENK and Bom expression following AMI reflects the role of neuropeptides in functional regulation of cardio-vascular system. Recommendations on application: the new data obtained can be used as normative during medical and biological scientific research; in patho-morphological and medico-legal diagnostics of cardio-vascular diseases accompanied by acute myocardial ischemia; in the development of new drugs; in medical education. Area of application: cellular biology, cytology, histology, neurochemistry, normal and pathological anatomy, normal and pathological physiology, pharmacology, legal medicine, cardiology, internal diseases. 23 15.02.16. . . . 1,39. .- 60 84/16. . «Times». . . 1,28. 60 . « ». 113. : . 1/187 , 6, 220006, ». , 18.02.2014. . ,
