The sensory function of the trigeminal nerve is to provide tactile, proprioceptive, and nociceptive afference by chemical stimulation. Various physical responses of the trigeminal nerve to stimuli help to defend against harmful substances. Recently, many studies have been conducted on solitary chemoreceptor cells innervated by trigeminal nerve. Most volatile organic compounds stimulate both the olfactory and trigeminal nervous systems. In general, the trigeminal nervous system is less sensitive than the olfactory nervous system. Studies have shown that sensation of the trigeminal nerve by chemical stimulation results in inhibition of olfaction. This indicates that the olfactory and trigeminal nerves interact with each other in the central nervous system. It is important to study various noxious stimuli acting on the trigeminal nerve in modern society where environmental concerns are intensifying.

Given the different effects of agricultural mechanization on various stages of wheat planting in Henan, this article selects 78 observation samples from Henan, a major wheat-growing province. It uses different research methods (multiple linear regression, social network analysis model, multi-layer sensory nerves network) to conduct a comparative study, and the calculation results of the model show that the experimental results have a strong convergence and consistency. Agricultural mechanization services have significant effects on the three stages of wheat planting: harvesting, plowing and sowing. A higher degree of mechanized service in several stages can reduce the cost of growing wheat on family farms.

Taste sensation is the process of converting chemical identities in food into a neural code of the brain. Taste information is initially formed in the taste buds on the tongue, travels through the afferent gustatory nerves to the sensory ganglion neurons, and finally reaches the multiple taste centers of the brain. In the taste field, optical tools to observe cellularlevel functions play a pivotal role in understanding how taste information is processed along a pathway. In this review, we introduce recent advances in the optical tools used to study the taste transduction pathways.

Purpose: Mass can compress around tissue and cause deviation of normal anatomical structures. Often, mass grows toward neurovascular pedicle and encircles depending on the nature of mature mass. Neglecting neurovascular involvement of the mass is a serious problem not to be overlooked. Authors have performed microscopic approach regarding mass involving the neurovascular pedicle in the hand. Materials and Methods: From January 2007 through February 2012, retrospective analysis for nine cases of mass involving neurovascular pedicles was done. Patients were evaluated preoperatively by ultrasonography or MRI and checked intraoperative finding. Masses were evaluated by site, preoperative evaluation, involved neurovascular pedicle, histopathologic diagnosis, complication, and recurrence. Results: The site of mass involving neurovascular pedicles was 4 cases on the wrist, 2 cases on the palm, 2 cases on the finger, 1 case on the hand dorsum. Involved neurovascular pedicles were 3 radial arteries and nerves, 3 proper digital arteries and nerves, 1 radial artery, 1 superficial branch of radial nerve, 1 common digital artery and nerve. The histopathologic diagnosis of mass were 3 ganglions, 2 giant cell tumors, 2 epidermal cysts, 1 fibroma, and 1 benign spindle tumor. There were 2 cases of recurrence and secondary excisions were performed. Conclusion: Neurovascular pedicle injury can lead to serious complication like sensory and motor disorders, distal part ischemia, and so on. In case of mass suspected neurovascular invasion, accurate preoperative evaluation such as ultrasonography or MRI is necessary. To prevent any neurovascular related complication during mass excision, delicate surgical technique using a microscope becomes essential.

Purpose: Study was to evaluate the operative results for tarsal coalition with tarsal tunnel syndrome. Materials and Methods: From Jan. 2005 to Mar. 2006, among a number of patients who were diagnosed with tarsal tunnel syndrome caused by tarsal coalition and treated surgically, 5 patients were closely observed for more than 12 months. All cases were talocalcaneal coalition and there were two male and three female patients with a mean age of 36 years (22-50 years). We used the Takakura rating scale as clinical evaluation. Results: All five patients had a burning pain in the sole or extended to toes and showed positive Tinel's sign. Sensory disturbances were observed in the distribution of the medial plantar nerves in four patients and in the area of the medial and lateral plantar nerves in one. Atrophy and weakness of the plantar muscles were seen in two patients. The mean Takakura scale in preoperative and postoperative was 3.4 points (1 to 5 points), 8.6 point (6 to 10 points). The mean follow up was 14.4 months (12 to 16 months). The postoperative results were excellent in two patients, good in two and fair in one. As postoperative complications, there were persistent swelling in one patient and a flexion disturbance of Hallux in one. Conclusion: The coalition resection performed on tarsal tunnel syndrome caused by tarsal coalition could improve a level of pains and neurological symptoms significantly. However, since there were some undesirable complications, a detailed explanation to patients is required prior to surgical treatment and study of such complications may be required.

Yukmijihwang-tang(YM) is used in Oriental medicine for treatments of diverse systemic symptoms including neurological dosorders. The present study was performed to examine potential effects of YM on growth-promoting activity of injured sciatic nerve axons. YM treatment in the injured sciatic nerve induced enhanced distal elongation of injured axons when measured 3 and 7 days after injury. Retrograde tracing of sciatic nerve axons showed YM-mediated increases in the number of DiI-labeled dorsal root ganglion (DRG) sensory neurons and spinal cord motor neurons at 3 days after injury. Hoechst nuclear staining showed that non-neuronal cell population was largely elevated by YM treatment in distal nerve area undergoing axonal regeneration. Furthermore, phospho-Erk1/2 protein levels were upregulated by YM treatment in the injured nerve area. These data suggest that YM may play a role in facilitated axonal regeneration in injured peripheral nerves. Further investigations of individual herbal components would be useful to explore effective molecular components and develop therapeutic strategies.

Transcranial direct current stimulation (tDCS) is a neuromodulatory technique that delivers a low-intensity direct current to the cortical areas, thereby facilitating or inhibiting spontaneous neuronal activity. This study was designed to examine the changes in various sensory functions after tDCS. A single-center, single-blinded, randomized trial was conducted to determine the effect of a single session (August 4 to August 29) of tDCS with the current perception threshold (CPT) in 50 healthy volunteers. Nerve conduction studies (NCS) were performed in relation to the median sensory and motor nerves on the dominant hand to discriminate peripheral nerve lesions. The subjects received anodal tDCS with 1mA for 15 minutes under two different conditions, with 25 subjects in each group. The conditions were as follows: tDCS on the dorsolateral prefrontal cortex (DLPFC) and sham tDCS on DLPFC. The parameters of the CPT was recorded with a Neurometer$^{(R)}$ at frequencies of 2000, 250 and 5 Hz in the dominant index finger to assess the tactile sense, fast pain and slow pain, respectively. In the test to measure the CPT values of the DLPFC in the anodal tDCS group, the values increased significantly in all of 250 and 5 Hz. All CPT values decreased for the sham tDCS. These results showed that DLPFC anodal tDCS can modulate the sensory perception and pain thresholds in healthy adult volunteers. This study suggests that tDCS may be a useful strategy for treating central neurogenic pain in rehabilitation medicine.

Objective : Gyehyuldeung (GHD) has been widely used in oriental medicine for the treatments of cardiovascular and neurological disorders. Thus, its potential facilitatory activity on axonal regeneration was investigated in the rats. Methods: Sprague-Dawley rats were given crush injury at the sciatic nerve and the changes of axon growth after nerve injury on each nerve injury model were investigated with anti-NF-200 antibody, DiI, GAP-43 protein and Cdc2 protein Results : GHD-mediated enhancement of axonal regeneration after crush injury was measured in both qualitative and quantitative ways by immunofluorescence staining with anti-NF-200 antibody and retrograde tracing of fluorescence dye DiI. GAP-43 protein levels were elevated by GHD treatments in the distal injured sciatic nerve and DRG sensory neurons. The neurite outgrowth of DRG sensory neurons was facilitated by GHD treatment when co-cultured with Schwann cells and astrocytes prepared from injured sciatic nerves and injured spinal cord tissues, respectively. It was observed that Cdc2 protein was up-regulated in co-cultured Schwann cells or astrocytes and Cdc2 protein signals were co-localized to a certain extent with those of phospho-vimentin protein. Conclusions : These results suggest that GHD may play a facilitatory role in axonal regeneration by acting on the injured axons and adjacent non-neuronal cells. The current findings may be useful for the development of therapeutic targets through more specific explorations on molecular interactions between herbal components and endogenous factors.
