선천성 고혈압 흰쥐(SHR)와 정상혈압 흰쥐에서 교감신경성 신경전달에 미치는 부신수질 및 renin-angiotensin계의 역할을 알아보기 위해, 부신수질을 제거하거나 angiotensin 변환 효소 억제제를 장기간 처치한 뒤 중추신경계가 파괴된 상태에서 절전신경을 자극했을 때 나타나는 승압반응과 대동맥의 catecholamine농도 및 angiotensin 변환 효소 활성도의 변화를 비교 검토하였다. 부신수질을 제거하더라도 중추신경계를 파괴하기 전후의 혈압에는 영향을 주지 못했으며, 절전 신경 자극에 의한 승압반응은, 자극 주파수에 의존적으로 증가하였으며 prazosin 전처치로서 거의 완전히 억제되었다. 정상혈압 흰쥐에서와는 달리, 선천성 고혈압 흰쥐에서는 부신수질을 제거했을 때는 절전신경 자극에 의한 승압반응이 부신수질을 제거하지 않는 군(이하 대조군)에 비하여 유의하게 약화되었다. SHR에서 부신수질 제거로 부신 catecholamine 함량은 현저히 감소되었고, 혈청의 angiotensin 변환 효소 활성도는 감소되는 경향을 나타내었다. 그러나 혈장 및 대동맥 절편의 catecholamine 함량, 대동맥 절편의 angiotensin 변환 효소의 활성도는 대조군과 유의한 차이가 없었다. 그러나 WKY에서는 부신수질이 제거된 군에서 대동맥 절편의 angiotensin 변환 효소의 활성도와 catecholamine함량이 대조군에 비해 유의하게 증가되어 있었다. Enalapril처치에 의해서 선천성 고혈압 흰쥐 평균 혈압은, 부신 catecholamine 함량 및 대동맥 절편의 angiotensin 변화 효소의 활성도와 함께 현저히 저하되어 정상혈압 흰쥐와 유사하였다. 그리고 선천성 고혈압 흰쥐에서 부신수질의 제거로 절전신경 자극에 의한 승압반응이 대조군에 비하여 약화되는 현상은 enalapril을 처치하였을 때는 관찰되지 않았다. 이상의 결과로 미루어보아 교감신경성 신경전달을 항진시키는 부신수질의 작용은 renin-angiotensin계의 활성화에 의존적이었으며, 부신수질의 제거로 정상혈압 흰쥐에서는 renin-angiotensin계가 보상적인 조절이 일어났으나, 선천성 고혈압 흰쥐에서는 보상적인 조절이 일어나지 않았다. To assess the role of adrenal medulla and renin-angiotensin system in the regulation of sympathetic neurotransmission, the pressor response to PNS was evaluated in pithed SHR and normotensive WKY or SDR with or without adrenal demedullation and/or enalapril pretreatment. Three weeks after adrenal demedullation, MAP and the heart rate of demedullated rats were similar to their corresponding sham-operated groups. The pressor response to PNS was frequency-dependent, and blocked by prazosin. In contrast to the normotensive rats, in SHR, the pressor response to PNS was attenuated in demedullated rats as compared with sham-operated rats. However, the attenuation of PNS-induced pressor responses in demedullated SHR was not observed in enalapril-treated SHR. The adrenal demedullation in SHR did not affect the plasma and aortic catecholamine contents in spite of the decreased catecholamine contents of adrenal gland, nor ACE activity in aortic strips. But, in WKY rats, the aortic catecholamines, especially epinephrine, contents as well as ACE activity were increased by adrenal demedullation. These results suggest that the facilitatory role of adrenal medulla in sympathetic neurotransmission depends upon the activation of renin-angiotensin system, and that the compensatory regulation of renin-angiotensin system takes place in normotensive rats but not in SHR.

Sodium Nitroprusside(SNP)를 사용한 유도 저혈압 마취시 Renin 활성치, Aldosterone, Epinephrine, Norepinephrine의 변동

강기택,구영권,우성,조강희,백세민 인제대학교 1991 仁濟醫學 Vol.12 No.3

악안면 성형재건술 환자 10명을 대상으로한 sodium nitroprusside(SNP) 유도 저혈압 마취에서 SNP를 주입한 후에 체내의 renin-angiotensin-aldosterone system과 sympathoadrenal system이 활성화되었음을 관찰할 수 있었다. Sodium Nitroprusside (SNP) is used during induced hypotension to decrease bleeding in operation site by direct relaxation of vascular smooth muscle. It is known that the infusion of SNP increases plasma renin activity and this activation of remain-angiotensin system is one physiologic mechanism opposing the hypotensive action of SNP. The purpose of this study was to determine plasma renin activity and activation of sympathoadrenal system following infusion of SNP for hypotensive anesthesia in 10 patients needed maxillofacial reconstructive surgery. Blood samples for analysis were drawn according the time sequence of SNP infusion ; Stage 1; After the induction and before SNP infusion, Stage 2 ; 30 min after when mean arterial pressure maintained 60-70 torr and within 30 min after SNP infusion, Stage 3;Before slopping of SNP, Stage4; 30 min after stopping of SNP. The results were as followings, 1) The duration of anesthesia and infusion of SNP were 197.7±131.3 Min and 100.2±40.3 min. 2) Total doses of 0.01% SNP solution were 115.2±36.4 ml through hypotensive anesthesia 3) PRA in stage 2,3 and 4 (25.3±7.6, 26.2±7.2 and 24.5±8.2 ng/dl/hr respectively) were significantly increased compared with the value of stage 1 (8.9±7.0ng/dl/hr) and the level of aldosterone in stage 2, 3, 4 (28.4±12.7, 33.6±20.0 and 32.9±18.0 mg/dl respectively) were significantly increased compared with the value of stage 1 (13.4±9.1 ng/dl). The increased values of PRA and aldosterone fowllowing infusion of SNP were continued eyen after the time of stopping SNP. 4) Norepinephrine in stage 2, 3(545±157.5, 347.7±115.0 pg/ml respectively) and epinephrine in stage 2,3 (178.4±58.7, 132±55.7 pg/ml respectively) were significantly increased compared with the values of stage 1(norepinephrine ; 236.2±107.3, epinephrine ; 111.8±73.9 pg/ml) and they were returned to the control value after slopping of SNP infusion 5) Sodium potassium and chloride were not changed significantly during SNP induced hypotensive anesthesia. In summary, the activity of renin-angiotesin-aldostprone system and sympathoadrenal system were increased following infusion of SNP during SNP induced hypotensive anesthesia.

Interleukin-6-producing paraganglioma as a rare cause of systemic inflammatory response syndrome: a case report

Yin Young Lee,Seung Min Chung 영남대학교 의과대학 2023 Yeungnam University Journal of Medicine Vol.40 No.4

Pheochromocytomas and paragangliomas (PPGLs) may secrete hormones or bioactive neuropeptides such as interleukin-6 (IL-6), which can mask the clinical manifestations of catecholamine hypersecretion. We report the case of a patient with delayed diagnosis of paraganglioma due to the development of IL-6-mediated systemic inflammatory response syndrome (SIRS). A 58-year-old woman presented with dyspnea and flank pain accompanied by SIRS and acute cardiac, kidney, and liver injuries. A left paravertebral mass was incidentally observed on abdominal computed tomography (CT). Biochemical tests revealed increased 24-hour urinary metanephrine (2.12 mg/day), plasma norepinephrine (1,588 pg/mL), plasma normetanephrine (2.27 nmol/L), and IL-6 (16.5 pg/mL) levels. 18F-fluorodeoxyglucose (FDG) positron emission tomography/CT showed increased uptake of FDG in the left paravertebral mass without metastases. The patient was finally diagnosed with functional paraganglioma crisis. The precipitating factor was unclear, but phendimetrazine tartrate, a norepinephrine-dopamine release drug that the patient regularly took, might have stimulated the paraganglioma. The patient’s body temperature and blood pressure were well controlled after alpha-blocker administration, and the retroperitoneal mass was surgically resected successfully. After surgery, the patient’s inflammatory, cardiac, renal, and hepatic biomarkers and catecholamine levels improved. In conclusion, our report emphasizes the importance of IL-6-producing PPGLs in the differential diagnosis of SIRS.

교감신경계가 암의 발전과 진행에 미치는 영향

박신형(Shin-Hyung Park),지규용(Gyoo-Yong Chi),최영현(Yung Hyu Choi) 한국생명과학회 2018 생명과학회지 Vol.28 No.1

생물체는 스트레스에 대처하기 위한 항상성 유지 기작을 가지고 있으나, 만성적이고 반복적인 스트레스는 카테콜아민과 같은 스트레스 호르몬의 과도한 방출로 인해 인체에 해로운 영향을 미친다. 교감신경계와 암과의 관련성을 분석하는 연구는 스트레스가 암을 악화시킬 수 있다는 오랜 가설을 바탕으로 이루어졌다. 다수의 전임상연구와 역학 연구결과는 교감신경계의 주요 신호전달경로인 β-adrenergic signaling을 조절하는 것이 암의 진행을 억제할 수 있음을 보여주고 있다. 교감신경계의 활성화는 암세포의 oncogene과 DNA repair 유전자 조절, 생존과 사멸 조절, EMT 및 전이 조절, 면역계와 혈관신생 조절, 세포외기질과 간엽세포 조절, 지방세포 조절 등을 통해 암세포와 종양미세환경에 광범위하게 영향을 미칠 수 있다. 오늘날 암의 성장과 관련된 분자적 기전을 차단하는 표적항암치료가 각광받고 있으나, 보상경로의 활성화와 항암제 내성 출현 및 여러 부작용으로 말미암아 임상적 실패를 거듭하면서 암의 생병리를 다방면에서 조절하는 전략이 새로운 치료법으로 대두되고 있다. 본 총설에서는 이러한 암의 전신적 조절인자로서 교감신경계가 암의 형성과 발전에 미치는 영향을 요약하고, 향후 새로운 암치료전략으로서 β-adrenergic signaling을 조절하는 약물의 임상적 활용가능성에 대해 논의하고자 한다. Living creatures possess long-conserved mechanisms to maintain homeostasis in response to various stresses. However, chronic and continuous exposure to stress can result in the excessive production of stress hormones, including catecholamines, which have harmful effects on health. Studies on the relationship between the sympathetic nervous system (SNS) and cancer have been conducted based on the traditional hypothesis that stress can promote cancer progression. Many preclinical and epidemiological studies have suggested that the regulation of β-adrenergic signaling, which mediates SNS activity, can suppress the progression of solid tumors. SNS activation has highly pleiotropic effects on tumor biology, as it stimulates oncogenes, survival pathways, the epithelial–mesenchymal transition, and invasion. Moreover, it inhibits DNA repair and programmed cell death and regulates the tumor microenvironment, including immune cells, endothelial cells, the extracellular matrix, mesenchymal cells, and adipocytes. Although targeted therapies on the molecular basis of tumor proliferation are currently receiving increased attention, they have clinical limitations, such as the compensatory activation of other signaling pathways, emergence of drug resistance, and various side effects, which raise the need for pleiotropic cancer regulation. This review summarizes the effects of the SNS on the development and progression of cancer and discusses the clinical perspectives of β-blockade as a novel therapeutic strategy for this disease.
