introduction: this study aimed to investigate the diurnal intraocular pressure fluctuations under dehydration conditions and the relationship between the intraocular pressure fluctuations and blood pressure. methods: the intraocular pressures (iop), body weights, as well as systolic and diastolic blood pressures (sbp, dbp) of 36 fasting healthy volunteers were recorded at 8:00 a.m. and 5:00 p.m...

the autonomic nervous system consists of a vast range of nerves and ganglions. anatomical studies have demonstrated that the sympathetic innervations of the head and neck are affected by the neurons that ramify from the cranial cervical ganglion (ccg). the ccg is the end of the sympathetic cervical trunk, which runs with the vagal nerve during its cervical course. in this study sixteen adult (2...

introduction:guillain-barre syndrome(gbs) is the most common cause of acute flaccid paralysis. respiratory failure is the most serious short-term complication of gbs and invasive mechanical ventilation is required in 30% of patients.moreover,60% of those who are intubated develop major complications including pnemonia,sepsis,gi bleeding and pulmonary embolism. thus respiratory failure predictio...

OBJECTIVE To analyze the distribution characteristics of cardiac autonomic nerves and to explore the correlation between cardiac autonomic nerve distribution and arrhythmia. DATA RETRIEVAL A computer-based retrieval was performed for papers examining the distribution of cardiac autonomic nerves, using heart, autonomic nerve, sympathetic nerve, vagus nerve, nerve distribution, rhythm and atria...
