  • The present study was undertaken to explore the role of autonomic nerves in the regulation of sodium transporters and water channels in the salivary gland. Rats were denervated of their sympathetic or parasympathetic nerves to the submandibular gland. One week later, the expression of Na,K-ATPase, epithelial sodium channels (ENaC), and aquaporins (AQP) was examined in the denervated and contralateral glands. The sympathetic denervation slightly but significantly decreased the expression of ${\alpha}1$ subunit of Na,K-ATPase, whereas the parasympathetic denervation increased it. The expression of ${\alpha}$-subunit of ENaC was significantly increased in both the denervated and contralateral glands either by the sympathetic or parasympathetic denervation. The sympathetic denervation significantly increased the expression of AQP5 in both the denervated and contralateral glands, whereas the parasympathetic denervation decreased it. It is suggested that the autonomic nerves have a tonic effect on the regulation of sodium transporters and AQP water channels in the salivary gland.

  • Heart rate variability(HRV) is the clinical consequence of various influences of the autonomic nervous system(ANS) on heart beat. HRV can estimate the potential physiologic rhythm from the interval between consecutive beats(RR interval or HRV data), but cardiovascular system governed by ANS is in relation to respiration and autonomic regulation. It is known as RSA representing respiration-related HR rhythmic oscillation. Because the mechanism linking the variability of HR to respiration is complex, it has so far been unknown well. In this paper, we tried to evaluate 5-min RR interval segments under control of respiration in order to find out a proper respiration rate that can estimate the ANS function. 10 healthy volunteers were included to evaluate 5-min HRV data under 4 different respiration-controlled environments; 0.03Hz, 0.1Hz, 0.2Hz, and 0.4Hz respiration. HRV data were analyzed both in the frequency and the time domain, with cross-correlation coefficient(cross-coeff.) for HRV and respiration signal. The results showed maximum cross-coeff. of 0.84 at 0.1 Hz and minimum that of 0.16 at 0.4Hz respiration. Cross-coeff was decreased at a faster rate from 0.1Hz respiration. All mean SDNN, RMSSD, and pNN50 of time domain measures were 108.7ms, 71.85ms, and 28.47%, respectively, and LF, HF, and TP of frequency domain measures were $12,722ms^2,\;658.8ms^2$, and $7,836.64ms^2$ at 0.1Hz respiration, respectively. In conclusion, 0.1Hz respiration was observed to be very meaningful from time domain and frequency domain analysis in relation to respiration and autonomic regulation of the heart.

  • Cardiovascular, respiratory and electrodermal responses to acute stress episodes modeled by combined presentation of intense white noise and performance of word recognition task with noise background were studied in 15 college students. Experimental procedure consisted in sessions with white noise, word recognition task presentation with noise background and test with noise background. Recorded physiological variables were analyzed in terms of their sensitivity to detect activation of sympathetic and parasympathetic branches of autonomic nervous system and thus reflect autonomic arousal level during shout-term stress-inducing experimental manipulations. It was shown that performance of effortful mental task with noise background elicited significant physiological responses typical for active coping behavior, namely electrodermal arousal and increased cardiovascular activity. this response profile was more profound as compared to white noise only or attending task in noise background. However, all physiological responses were mostly phasic, without long-term tonic changes, since almost all variables recovered to their initial baseline levels, suggesting that dominant autonomic mechanisms in transient acute stress episodes were of parasympathetic nature (withdrawal in stress with subsequent activation in restoration period), while sympathetic contribution was not long-lasting. Nevertheless, increased number of stressors and their longer exposure may result in higher profile of tonic sympathetic arousal and reduced functional role of vagal mechanisms in autonomic balance regulation.

  • This study assessed behavioral characteristics of 73 normal neonates in Daegu area using the NBAS. Being one of few studies on this topic, the study is to document and to accumulate data on the neonatal behaviors of Korean babies. Overall scores were at moderate levels in 6 behavioral clusters including Habituation, Social Interactive, Motor System, State Organization, and State Regulation. Autonomic Stability showed relative stableness. Scores of Orientation were higher in neonates of working mothers and rural mothers. Neonates of mothers with no abortion history have higher scores in Motor System and State Organization. Score of State Organization was higher in neonates of mothers with no habitual use of amenity during their pregnancy. Scores of Habituation and State Organization, as well as scores of Motor System with State Organization, State Regulation and Autonomic Stability were positively correlated. Scores of Habituation and State Organization indicate that babies are agreeable and even tameable that is advantageous for attachment to caregiver.

  • This study was conducted to investigate the thermoregulatory responses and wearing behavior of the cold-sensitive men when exposed to the mild cold of 14$^{\circ}C$. Two sessions of experiment were carried out and five healthy young men for the cold-sensitive group(CSG) and four healthy young for the cold-insensitive group(CIG) participated in the study as subjects CSG maintained rectal temperature lower than CIG due to their thicker clothing resulted in larger decrease of rectal temperature. CSG maintained skin temperatures higher than CIG. CSG felt cooler than CIG but wore thicker clothing for thermal comfort and this made keep their sensation warmer. These results were discussed in terms of autonomic and behavioral temperature regulation.

  • It is widely known that protein tyrosine kinases (PTKs) are involved in controlling many biological processes such as cell growth, differentiation, proliferation, survival and apoptosis. An $\alpha3\beta4$ subunit combination acts as a major functional acetylcholine receptor (nAChRs) in male rat major pelvic ganglion (MPG) neurons, and their activation induces fast inward currents and intracellular calcium increases. Recently it has been reported that the activity of acetylcholine receptors (AChRs) in some neurons can be negatively regulated by PTKs. However, the exact mechanism of regulation of nAChRs by PTKs is poorly understood. Therefore, we examined the potential role particular in nAChR by PTK using electrophysiology and calcium imaging in male rat MPG neurons. ACh induced inward currents and $(Ca^{2+})_i$ increases in MPG neurons, concomitantly. These responses were inhibited by more than 90% in $Na^+$- or $Ca^{2+}$- free solution. $\alpha$-conotoxin AuIB, a selective $\alpha3\beta4$ nAChR blocket, inhibited ACh-induced inward currents. Genistein (10 $\mu$M), a broad-spectrum tyrosine kinase inhibitor, markedly decreased ACh-induced currents and $Ca^{2+}$ transients, whereas 10 $\mu$M genistin, an inactive analogue, had little effect. Overall these data suggest that the activities of $\alpha3\beta4$ AChRs in MPG neurons are positively regulated by PTK. In conclusion, trosine kinase may be one of the key factors in the regulation of $\alpha3\beta4$ nAChRs in rat MPG neurons, which may play an important roles in the autonomic neuronal function such as synaptic transmission, autonomic reflex, and neuronal plasticity.

  • 본 연구는 연소담배와 비교해 서로 다른 가열담배(heated tobacco products, HTPs) 사용 시 혈역학적 지표들의 급성 반응을 비교하고, 급성 HTPs 에어로졸 노출이 심장 자율신경조절(cardiac autonomic regulation, CAR)에 미치는 영향을 탐색하려는 목적으로 수행되었다. 또한, 서로 다른 연초 스틱 간 급성 심혈관 효과의 비교 검증을 목표로 하위연구를 설계했다. 외관상 건강한 남성 흡연자 16명은 개방표지, 무작위 교차시험으로, 최소 48시간 세척기간과 함께 비-흡연(non-smoking, NS), 담배 흡연 및 서로 다른 두 가지 HTPs 사용 세션을 각각 수행했다. 하위연구는 NS와 함께 서로 다른 두 가지 연초 스틱 간 급성 심혈관 효과를 비교하기 위해, 참여자 중 8명을 대상으로 실시되었다. 수축기와 확장기 혈압 및 CAR을 반영하는 심박변이도(heart rate variability, HRV)가 각 세션 시작 전, 제품 사용 중 그리고 사용 후 30분까지 평가되었다. NS 동안 혈역학적 변화는 통계적 차가 없었으나, HTPs 에어로졸에 급성 노출은 담배 연기와 상응하는 수축기와 확장기 혈압의 유의한 증가를 초래했으며, 이들 지표에서 HTPs 기기 간 통계적 차는 없었다. 연소담배와 HTPs 사용 후 통계적으로 유의한 심장 교감신경활동(cardiac sympathetic nerve activity, CSNA)의 급성 증가와 심장 미주신경 긴장도(cardiac vagal tone, CVT)의 급격한 저하가 나타났다. 사용 기기와 독립적으로 HTPs 사용에 따른 CSNA와 CVT 반응은 연소담배와 통계적 차가 없었다. 서로 다른 두 가지 연초 스틱은 NS와 비교해 혈역학적 지표들의 유의한 증가를 유도했으나, 연초 스틱 간 통계적 차는 없었다. CVT는 두 가지 연초 스틱 사용에 따라 유의하게 감소했으며, 연초 스틱의 종류에 따라 CVT 저하에 통계적 차가 있었다. 이상의 결과들은 HTPs 에어로졸 노출이 사용 기기와 독립적으로 연소담배와 동등한 급성 심혈관 효과를 유도할 수 있으며, 연초 스틱의 종류에 따라 급성 CAR 저하가 강화될 수 있음을 시사한다.

  • 가열담배(heated tobacco products, HTPs) 에어로졸 내 유해 성분들의 수준은 담배 연기와 비교해 현저히 낮은 것으로 보고되었지만, HTPs 사용이 담배 흡연과 연관된 심혈관 위험을 완화할 수 있는지는 불분명하다. 현재 연구는 습관성 흡연자들을 대상으로 담배 흡연에서 HTPs 사용으로의 단기간 전환이 심장 자율신경조절(cardiac autonomic regulation, CAR)에 미치는 영향을 탐색하기 위한 목적으로 수행되었다. 건강한 20대 남성 흡연자 7명은 5일 동안 담배 흡연(cigaette smoking, CS), 3가지 서로 다른 HTPs 사용(IQOS use, IQ; lil SOLID use, LS; lil HYBID use, LH) 혹은 흡연 중단(non-smoking, NS)으로 구성된 개방표지, 무작위 교차설계 시험을 완료했다. 각 세션은 1주의 세척 기간으로 분리되었으며, 세션당 할당된 제품 사용 전과 사용 후 24, 48, 72, 96 및 120시간에서 생체 이물[CO (carbon monoxide) and COHb (carboxyhemoglobin)], 혈류역학적 변인(systolic and diastolic blood pressure) 및 CAR 조절을 반영하는 HRV (heart rate variability) 지표들의 수준이 평가되었다. 호기 CO 및 COHb 수준은 NS에서만 통계적으로 유의하게 감소했다. 모든 세션 내 혈류역학적 변인에서 통계적 변화는 없었다. 그러나r HRV 스펙트럼 분석에서 lnHF (log-transformed high frequency, lnHF)는 NS를 포함한 IQ와 LS에서 유의하게 증가하였으며, HFnu (normalized HF)는 NS와 LH에서 통계적으로 증가하였다. lnHF와 HFnu는 각각 세션 간 시간에 따른 유의한 상호작용효과를 나타냈다. 현재 연구는 습관성 흡연자들에게서 HTPs 사용으로의 단기간 전환이 담배 흡연에 의한 심장 미주신경 긴장도 저하를 개선하여 CAR에 영향을 미칠 수 있음을 시사한다.

  • Major pelvic ganglia (MPG) in rats are an unique autonomic ganglia, containing both sympathetic and parasympathetic neurons related with the function of bladder, penis and bowel. It has been widely known that ionotropic $GABA_A$ receptors are the molecular target of $\gamma$-aminobutric acid (GABA), a major inhibitory neurotransmitter in central nervous system. However, their functions and regulations of $GABA_A$ receptors expressed in autonomic ganglia have been poorly understood. 1 examined the modulatory role of adenylyl cyclase (AC) and protein kinase A(PKA) on $GABA_A$-induced inward currents in the neurons of rat MPG. $GABA_A$ receptors were identified using immunofluorescent labeling in the rat major pelvic ganglion. Electrophysiological experiments were performed to record the activities of $GABA_A$ receptors. $GABA_A$ receptors were expressed only in sympathetic neurons. GABA induced marked inward currents in a concentration-dependent manner. Mucimol ($5{\mu}M$), a $GABA_A$ receptor agonist induced inward currents were significantly reduced in the presence of SQ 225361 $20{\mu}M$, a AC inhibitor and myristoylated PKA inhibitor 100 nM. In addition, forskolin ($1{\mu}M$), AC activator, augmented the GABA induced currents. The activation of AC/PKA-dependent pathway could involve in the regulation $GABA_A$ receptors, expressed only in sympathetic neurons of rat MPG. These findings are helpful for the better understanding the function of various pelvic organs innervated by MPG.
