| Abstract | Cisplatin exerts its cytotoxic effect through distinct DNA lesions, leading to peripheral neuropathy. The risk of sensory neuropathy is a common problem during cancer treatment with cisplatin, leading to somatic hyperalgesia. Yet, data focussing on cisplatin-induced impairment of the autonomic nervous system are limited. The present study was aimed to investigate the effect of recombinant human erythropoietin (rhEPO) on cisplatin-induced visceral hyperalgesia.C57BL/6 mice were treated either with cisplatin (2 mg/kg, once per week) or with cisplatin (2 mg/kg, once per week) plus rhEPO (40 μg/kg, 3 times per week) for 8 weeks. Controls were treated with saline. To quantify the visceromotor response (VMR) at week 9, standardized electrodes were implanted into the external oblique musculature for electromyographic recordings. After that, animals were decapitated and dorsal root ganglia (DRG) was removed for transmission electron microscopy studies.Cisplatin-treated mice showed a significant increase of VMR compared to the controls [(7080 ± 969) vs (2864 ± 279); P < 0.001], while rhEPO dramatically counteracted this effect [(2962 ± 336) vs (7080 ± 969); P < 0.001)]. Transmission electron microscopy revealed cisplatin-induced structural lesions of nuclear membrane in DRG cells, which could be ameliorated by rhEPO.Erythropoietin can significantly ameliorate the cisplatin-induced visceral hyperplasia and DRG nuclear membrane structure damage in mice, indicating a neuroprotective role of erythropoietin.顺铂是肿瘤化疗的常用药物, 主要通过损伤细胞DNA 发挥细胞毒性作用。在肿瘤治疗过程中, 顺铂往往会引起周围神经病变, 进而导致痛觉增敏。本文就重组人红细胞生成素(recombinant human erythropoietin, rhEPO)是否能抑制顺铂引起的内脏痛觉增敏进行研究。C57BL/6系小鼠经顺铂或顺铂与rhEPO 共同作用8周后, 用肌电检测法观察在结肠直肠扩张性刺激下内脏运动的变化, 并用透射电子显微镜观察背根神经节细胞结构水平的变化。顺铂能显著增强结肠直肠扩张性刺激下小鼠的内脏运动反射, 而rhEPO 则能显著减轻这一作用。此外, 透射电子显微镜观察显示rhEPO能显著减轻顺铂引起的背根神经节细胞核膜损伤。促红细胞生成素具有神经保护作用。 |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
