  • Charcot spinal arthropathy is a rare, progressive type of vertebral joint degeneration that occurs in the setting of any preexisting condition characterized by decreased afferent innervation to the extent that normal protective joint sensation in the vertebral column is impaired. The authors report on a case of Charcot arthropathy of the lower lumbar spine mimicking a spinal tumor following cervical cord injury.

  • Patients with facial paralysis, in whom nerve damage is irreparable or in whom the innervation of the paralyzed musculature cannot be restored by nerve suture, grafting, or cross-face nerve transplantation, should be offered some form of reconstructive static and dynamic aid. Temporalis muscle-fascia unit used as a circumorbital sling and motor unit is a dynamic controlled reconstructive procedure, but it has several disadvantages such as wide surgical exposure, bulky-looking at lateral canthal area, insufficient voluntary control. This is a case report of facial palsy of posttraumatic lagophthalmos of 41-year-old male, which was corrected by temporalis muscle-tendon transfer with plantaris tendon transplantation.

  • The inferior alveolar nerve provides unilateral innervation to the dentition, labial mucosa and skin from about commissure to the mental protuberance. Injury to this nerve resulting in sensory impairment can be a distressing problem to some patients. The causes of this problem include trauma, extraction, implant surgery and any maxillofacial surgery and generally the altered sensation is temporary. The surgical procedure has been the most common treatment for this condition but it has some complications. The antidepressants and anticonvulsants have been effective to the treatment of trigeminal dysesthesia. This case report suggests that the use of antidepressants and anticonvulsants is an alternative method to treat the paresthesia after implant surgery or extraction.

  • Positron emission tomogrpahy (PET) represents the most advanced scintigraphic imaging technology. With the increase in availability of PET, the clinical use of PET has grown in medical fields. This can be employed for cardiovascular research as well as for clinical applications in patients with various cardiovascular disease. PET allows non-invasive functional assessment of myocardial perfusion, substrate metabolism and cardiac innervation and receptors as well as gene expression in vivo. PET is regarded as the gold standard for the detection of myocardial viability, and it is the only method available for the quantitative assessment of myocardial blood flow. This review focuses on the clinical applications of myocardial perfusion PET in coronary artery disease.

  • The vocal fold has three major function-phonation, respiration and protection, and is richly innervated. The vocal 1314 its autonomic innervation-adrenergic and cholinergic from superior cervical ganglion and the vagus nerve, respectively. The action of both system account for vasoregulation and glandular activity. In e vocal fold several kin of neuropeptides, including SP, CGRP, VIP, TH, NPY, ENK have been reported at the animal including cat or dog. But information regarding the distribution of autonomic nerve fibers containing neuropeptides in the human vocal fold is lacking. Two neuropeptides are of special interest : 1) vasoactive intestinal polypeptide(VIP)that is known to be contained in the parasympathetic(cholinergic) neuron. 2) tyrosine hydroxylase(TH)is located in the cytoplasm of noradrenergic neuron and is the rate-limiting enzyme in noradrenaline synthesis. To understand specific autonomic function of vocal fold we did immunohistochemical examination of VIP and TH in the human vocal fold.

  • 가토 적출 신동맥에 있어서 purinergic 신경 분포를 perivascular nerve stimulation을 통해서 확인하였다. 1. 가토 적출 신동맥은 perivascular nerve stimulation에 의해 수축성 반응을 나타내었다. 2. Perivascular nerve stimulation에 의한 수축현상은 자극의 크기와 자극의 빈도에 의존적이었으며, 내피세포의 유무에는 영향을 받지 않았다. 3. Perivascular nerve stimulation에 의한 수축현상은 prazosin$(1{\mu}M)$에 의해 강하게 억제되어졌으며, tetrodotoxin$(1{\mu}M)$ 또는 ${\alpha},{\beta}-methylene$ATP$(10{\mu}M)$에 의한 $P_{2x}-purinoceptor $ desensitization에 의해 완전히 수축현상이 사라졌다. 이와같은 결과는 가토 신동맥에는 purinergic신경이 분포되어 있으며, perivascular nerve stimulation에 의해 purinergic 신경전달물질이 norepinephrine과 함께 유리되어지는 것을 시사하고 있다.

  • Eruption of the teeth can be disturbed by crowding, ectopic eruption path, retention for pathologic condition of follicle and periodontal ligament, local disturbances in the innervation, and delayed eruption for overlying obstacles in the eruption path. Eruption disturbance of permanent posterior teeth is taken with diverse therapeutic approaches according to the patient age, cooperation of patient, tooth position and maturity, degree of impaction, clinical features, and repercussion on the neighboring teeth. However, delayed treatment usually results in less favorable outcomes. Therefore, In order to prevent this situation, periodically radiographic examinations during the early mixed dentition period and early diagnosis of eruption disturbances of permanent posterior teeth are recommended.

  • Aim of this study was to discover the projection area of the first cervical spinal nerve. Subcutaneous injection of wheat germ agglutinin-horseradish peroxidase(WGA-HRP) was done at five points of young dogs scalp and face. After two days of survival time, animals were sacrificed by perfusion through the left ventricle of the heart. Trigeminal ganglion, first and second cervical dorsal root ganglion, superior cervical ganglion, middle cervical ganglion and stellate ganglion were removed. Projection area of wheat germ agglutinin-horseradish peroxidase in vestigated into above ganglions. Projection into the first cervical dorsal root ganglion and stellate ganglion was not found. This experiment is deemed valuable for the study of neuronal connection on the central nervous system.

  • The genitourinary tract and gastrointestinal system are interdependent but share the same embryological origin, pelvic region, and sacral innervation. Although children with voiding disturbances often present with bowel dysfunction, this coexistence was considered coincidental until recently. However, it is now accepted that dysfunction in emptying of both systems is interrelated. Afferent impulses carrying sensory information are transmitted through the spinal cord and brainstem toward several cortical and subcortical areas, resulting in conscious control of the bladder and bowel. Alteration in these afferent pathways can result in dysfunction, including urinary and fecal incontinence. Distal gastrointestinal tract problems such as constipation might induce an inhibitory rectovesical reflex that interferes with normal voiding. Therefore, lower urinary tract function seems to be closely associated with distal gastrointestinal tract function.

  • 후두근의 운동지배신경에 관하여 일반적으로 알려진 사실은 윤상갑상근이 상후두신경의 의지에 의하여 지배되는 것 외에는 모든 후두내근이 반회후두신경에 의하여 지배된다는 것이다. 이중에서 갑상피열근이나 피열근에 대하여 상후두신경과 반회후두신경의 이중지배(dual supply)는 오랜동안 논란이 되어왔다. 특히 피열근에 분포하는 신경은 반회후두신경의 피열분지에 의하여 지배되며 또한 상후두신경의 내지의 일부인 ramus porforantes에 의해서도 이중지배를 받는다고 알려져 왔다. 그러나 한편 이러한 피열근의 운동신경지배 중 상후두신경의 역할에 대해서 적지 않은 보고가 후두의 신경해부학적인 고찰 및 전기적 자극을 통한 연구에서 단지 피열근 근처에서 twig을 형성할 뿐, 직접적인 운동지배 현상은 보이지 않음을 입증하여 피열근은 오직 반회후두신경에 의하여 운동지배된다고 주장하였다.
