The main cause of diabetic neuropathy, one of the most debilitating complications, is the chronic hyperglycemia, the increase sorbitol or the decrease of nerve growth factor(NGF). NGF, a protein, plays a major role in the development and maintenance of peripheral nervous system. Systemic administration of NGF prevents manifestations of neuropathy in rodent models of diabetic neuropathy. In the previous investigation, we report the hypoglycemia effect of Dioscorea rhizoma extract(DRE) in diabetic mice. The present study shows protective effect of DRE on diabetic neuropathy by induction of NGF protein. We investigated the NGF level in salivary gland and sciatic nerve of normal mouse and the effect of DRE on sciatic nerve conductivity and thermal hyperalgesia test in Type 2 db/db mouse. DRE increased endogenous NGF level in salivary gland and sciatic nerve of mouse. And sensory nerve conductivity velocity(SNCV), motor nerve conductivity velocity(MNCV) and thermal hyperalgesia increased in DRE treatment mice compared with control group. On the basis of our results, we conclude that DRE increase induction of endogenous NGF level and have protective effect on diabetic neuropathy by induction of NGF. Therefore, we propose that long-term use of DRE might help prevention of diabetes-associated complication; diabetic neuropathy.

당뇨병성 다발성 신경병증 환자들을 진단하는 전류지각 역치 시험과 진동 감각 지각 역치의 임상학적 유용성에 대한 평가는 당뇨병성 다발성 신경병증에 대한 진단방법 중의 하나이다. 현재까지 당뇨병성 다발성 신경병증 환자들에 대해 몇 가지 방법들이 사용되어 왔는데, 예를 들면, 하지 신경병증 장애 시험, 신경전도 시험, 냉각감지 역치 시험, 열-고통 역치 시험 등을 들 수 있다. 그러나, 이들 대부분의 시험은 고가이거나 시험하는데 많은 시간을 필요로 한다. 본 논문에서는 진동 감지 능력을 평가하는 새로운 기구가 소개되고, 이를 위해 환자의 말초 신경을 자극하는 보이스 코일 모터(voice coil motor)와 전류 증폭기를 제작하였다. 또한, 당뇨병성 다발성 신경병증 환자들의 정량적 진동 감지 수준을 측정하기 위하여 진동 감지 역치 시험을 센싱하고 구동하는 소프트웨어가 개발되었다.

Objective : Pituitary apoplexy (PA) is described as a clinical syndrome characterized by sudden headache, vomiting, visual impairment, and meningismus caused by rapid enlargement of a pituitary adenoma, We retrospectively analyzed the clinical presentation and surgical outcome in PA presenting with cranial neuropathy. Methods : Twelve cases (33%) of PA were retrospectively reviewed among 359 patients diagnosed with pituitary adenoma, The study included 6 males and 6 females, Mean age of patients was 49,0 years, with a range of 16 to 74 years, Follow-up duration ranged from 3 to 20 months, with an average of 12 months, All patients were submitted to surgery, using the transsphenoidal approach (TSA). Results : Symptoms included abrupt headache (11/12), decreased visual acuity (12/12), visual field defect (11/12), and cranial nerve palsy of the third (5/12) and sixth (2/12) Mean height of the mass was 29.0 mm (range 15-46) Duration between the ictus and operation ranged from 1 to 15 days (mean 7.0) The symptom duration before operation and the recovery period of cranial neuropathy correlated significantly (p = 0.0286) TSA resulted in improvement of decreased visual acuity in 91.6%, visual field defect in 54.5%, and cranial neuropathy in 100% at 3 months after surgery. Conclusion : PA is a rare event, complicating 3.3% in our series, Even in blindness following pituitary apoplexy cases, improvement of cranial neuropathy is possible if adequate management is initiated in time, Surgical decompression must be considered as soon as possible in cases with severe visual impairment or cranial neuropathy.

Purpose: The purpose of this study was to examine the mediation of psychological distress in the relationship between disturbance in ADL from chemotherapy induced peripheral neuropathy and quality of life in order to provide a basis for planning nursing interventions to improve the quality of life in cancer patients. Methods: A purposive sample of 130 patients treated with chemotherapy were recruited in the cross-sectional survey design. Data were collected using self-report questionnaires. The instruments were the Chemotherapy Induced Peripheral Neuropathy Assessment Tool (CIPNAT), Hospital Anxiety Depression Scale (HADS), and Functional Assessment of Cancer Therapy-General (FACT-G). Results: The mean score for disturbance in ADL from chemotherapy induced peripheral neuropathy was 3.30. Overall quality of life was 2.48. The mean score was 1.04 for psychological distress. The prevalence was 35.4% for anxiety and 47.7% for depression. There were significant correlations among the three variables, disturbance in ADL from chemotherapy induced peripheral neuropathy, psychosocial distress, and quality of life. Psychosocial distress had a complete mediating effect (${\beta}$= -.74, p <.001) in the relationship between disturbance in ADL from chemotherapy induced peripheral neuropathy and quality of life (Sobel test: Z= -6.11, p <.001). Conclusion: Based on the findings of this study, nursing intervention programs focusing on disturbance of ADL management, and decrease of psychological distress are highly recommended to improve quality of life in cancer patients.

Background: The chemotherapeutic agent oxaliplatin can cause acute and chronic forms of peripheral neuropathy. The aim of this study was to evaluate the incidence of chronic neuropathy and its risk factors in colorectal cancer (CRC) patients treated with FOLFOX or XELOX regimens in the Oncology Ward of Hazrate-Rasoul Hospital in Tehran. Materials and Methods: A total of 130 patients with CRC were entered into our study, aged over 18 years, without history of receiving other neurotoxic agents or other predisposing factors such as diabetes or neurologic diseases and kidney and liver dysfunction. For the FOLFOX regimen, patients received oxaliplatin, 85mg/m2, every 2 weeks for 12 courses and with the XELOX regimen, oxaliplatin was $130mg/m^2$, every 3 weeks for 8 courses. Based on Common Toxicity Criteria (CTC or NCI-CTC v.3), the patients were divided into 5 groups (grades) based on the severity of their symptoms. Results: Fifty-seven patients (43.8%) were male and 73(56.2%) female. Some 19 patients (14.7%) had BMI<20, 97(74.6%) were between 20-25 and 14 (10.8%) ${\geq}25$. In 105 patients (80.7%) neuropathy was found. There was significant correlation between BMI, hypomagnesaemia and especially, severity of anemia in patients with neuropathy compared to those without. Conclusions: Oxaliplatin regimens can induce chronic neuropathy in CRC patients, with anemia, high BMI and hypomagnesaemia as risk factors that can predispose to this kind of neurotoxicity.

In this case, it is considered that the cause of the lower limb Flaccidity-syndrome is the peripheral neuropathy accompanied with inflammation and in oriental medicine, it is understood that the factors such as lung fluid consumption caused by heat-evil, wetness-heat evil cause the lower limb Flaccidity-syndrome. Because the peripheral neuropathy is regarded as a neuropathy with a series of inflammation reaction producing inflammatory neuropeptides such as substance P, prostaglandin ect., in western medicine, nonsteroidal antiinflammation drug;NASID, lidocaine, capsaicine are prescribed to control this neuropathy. In the view of treatment of the lower limb weakness, Wooseul-tangkami is used to remove the wetness-heat evil and we had a electronic acupuncture on the Yangmyung channel(陽明經) selected in The Yellow Emperor's of internal Medicine and also on Panggwang channel(膀胱經) considered as painful lesion. We experineced a case of the lower limb Flaccidity-syndrome diagnosed as the peripheral neuropathy the patient was treated by wooseul-tangkami, a acupuncture on Yangmyung channel and also Panggwang channel and had a significant improvement in gait ability and the range of motion.

Purpose: Purpose of this study was to investigate relationships and influence of peripheral neuropathy, sleep, and quality of life in patients with gastric cancer who are receiving chemotherapy. Methods: Participants were 131 patients with gastric cancer being treated at a chemotherapy outpatient clinic and receiving chemotherapy. Data were analyzed using descriptive statistics, t-test, ANOVA, and multiple regression analysis with the SPSS program. Results: Mean score for peripheral neuropathy was 24.66, for sleep, 6.71 and for quality of life, 67.69. Peripheral neuropathy had a significant positive correlation with sleep (r=.26, p=.003) and sleep had a significant negative correlation with quality of life (r=-.50, p<.001). The regression model explaining quality of patients'lives was significant (F=11.91, p<.001), peripheral neuropathy, sleep, and pain due to anticancer drugs and number ofneurotoxic anticancer drugs explained 25.1% of the variance in quality of life and sleep was the most important factor. Conclusion: To improve the quality of life for these patients, individualized nursing interventions for pain should be provided according to number of anticancer drugs in the chemotherapy. Also there is a need to identify ways to assess peripheral neuropathy and sleep disorders that are appropriate in the treatment and reduce side effects during treatment.

Objectives: The purpose of this study is to investigate the mechanism of acupuncture for treating chemotherapy-induced peripheral neuropathy. Methods: Based on domestic and international papers reported until October 2020, experimental papers on "chemotherapy induced peripheral neuropathy", "mechanism", and "acupuncture" were set up to identify the mechanisms of chemotherapy induced peripheral neuropathy. A total of seven papers were selected and searched: one pilot paper for people and six experimental papers for rats. Results: In the pilot paper studied by Bao, T., the effect of EA was demonstrated but no significant results were produced for the mechanism. Moon et al. derived the association between EA and plasma 𝛽-endorphin in rat experimental studies on oxalilatin-induced cold hypersensitivity. Meng et al. found relevance to 𝜇, 𝛿, and 𝛿 opioid through EA stimulation in paclitaxel-induced peripheral neuropathy. Lee et al. studied the relationship between EA and muscarin and 5-HT in rat experiments on oxaliplatin-induced coldness, associated with 5-HT and EA, especially with 5-HT3 receptors. Choi et al. revealed the association of adrenaline and opioid acting on 𝛼2- and 𝛽 adrenaline receptors with EA in rat experiments on paclitaxel-induced neuralgia. In rat experiments on oxaliplatin-induced neuralgia reported by Lee, 𝛽-endorphin and encephalin were studied to be mediated by EA. Zhang, T. et al. revealed in the paclitaxel induced rat experiment that EA activates 5-HT. Conclusion: It is inferred that peripheral neuropathy caused by anticancer drugs can be reduced by activating the action of 5-HT, 𝛽-endorphin, and encephalin through the descending inhibitory pathways. cell differentiation, herbal medicine, Pongamia, stem cells

연구배경: 수면 무호흡 증후군에서 고혈압, 허혈성 심질환, 심부정맥등과 같은 심혈관 합병증과 주간 과다 졸음증은 주간 사고와 사망율의 증가와 관계가 있다. 수면 무호흡 증후군 환자에서의 심혈관 합병증의 원인으로는 수면중의 저산소혈증과 자율 신경 장애가 중요한 역할을 한다. 현재까지 수면 무호흡 증후군 환자에서 자율 신경 장애 유무에 대해서는 상반된 결과가 발표되고 있으며 발생기전도 잘 밝혀져 있지 않다. 저자들은 수면 무호흡 증후군 환자에서 자율 신경 장애 검사로 심혈관 자율 신경 장애 검사법이 유용한 검사가 될 수 있을지를 알아보았고 자율 신경 장애의 유무를 확인하였으며 이들 장애가 의미있는 상관 관계가 있는 인자를 알아보았다. 방 법: 수면 다원 검사에서 수면 무호흡 증후군으로 진단된 환자와 건강한 대조군에서 심혈관 자율 신경 장애 검사를 실시하여 환자군에서 자율 신경 장애 유무를 관찰하였으며 또한 수면 무호흡 증후군에서 심혈관 자율 신경 장애 검사가 유효한 검사법이 될 수 있을지를 알아 보았다. 또한 심혈관 자율 신경 장애 검사 결과와 수면 다원 검사 결과를 비교 분석하여 자율 신경 장애와 관계있는 인자를 알아보았다. 결 과: 수면 무호흡 증후군 환자에서 심혈관 자율 신경 장애 검사법의 결과 환자군에서 대조군보다 Valsalva maneuver 에서 유의한 차이를 보이면서 낮게 측정되었으며 나머지 항목에서는 유의한 차이가 없었다. 자율 신경 장애의 정도를 나타내는 자율 신경 장애 접수는 환자군이 $1.10{\pm}0.55$점으로 대조군의 $0.30{\pm}0.36$ 점보다 의의있게 높았으며, 교정한 QTc 간격도 환자군이 $423.93{\pm}18.44msec$, 대조군이 $396.93{\pm}19.85msec$로 두 군간에 유의한 차이를 보였다 (p<0.001). 그러나 자율 신경 장애 접수와 교정한 QTc 간격사이에는 상관 관계가 없었다 (r=0.410, p=0.073). 자율 신경 장애 점수와 수면 다원 검사에서 측정된 항목사이에는 유의한 상관 관계를 가지는 항목을 관찰할 수 없었다. 자율 신경 장애 정도를 유형에 따라 5가지로 분류하고 환자의 분포를 당뇨병 환자와 비교해 본 결과 두 질환은 서로 다른 분포를 보였다. 결 론: 수면 무호흡 증후군 환자에서 심혈관 자율 신경 장애 검사법을 적용하여 자율 신경계의 장애가 있음을 확인할 수 있었으며 심혈관자율 신경 장애 검사법이 수면무호흡 환자의 자율 신경 장애를 평가할 수 있는 유용한 검사법이었다. 앞으로 자율 신경 장애의 발생에 관여하는 인자를 밝히기 위한 더 많은 연구가 시행되어야 할 것으로 생각된다.
