Background: The aim of this pilot study was to assess the safety and dosing of scolopendrid pharmacopuncture (SPP).Methods: A total of 40 healthy Sprague-Dawley rats (males and 20 females 20) were selected following a 7-day inspection and acclimation period. SPP was administered via intramuscular injection, over a 2-week period using 3 doses including a high-dose [0.84 mg of scolopendrid per kg of body weight (BW)], a meddose (0.42 mg/kg BW), and a low-dose (0.21 mg/kg BW). The control group was injected with sterile water into the muscles. Unusual changes caused by administration of the test substance were observed. Weight, feed intake, organ weight, and hematological examinations were compared among the groups. Using the SPSS statistical program, Levene’s test was performed to evaluate the homogeneity of variances, and a one-way ANOVA test was subsequently performed to assess the significance between each test group.Results: During the experiment no animals died. Weight change, food consumption, organ weight, hematological test, and blood biochemical tests showed no significant differences in the treatment groups compared to controls.<br>Conclusion: No toxicological changes related to the administration of test substances were observed. Therefore, the LD<sub>50</sub> (lethal-dose that kills 50%) of scolopendrid pharmacoupuncture in rats was greater than 0.84 mg/kg.

Introduction: The aim of this study is to report on the effectiveness of Korean medicine to improve symptoms of chemotherapy-induced peripheral neuropathy (CIPN). Some patients are treated with medication, but medications may have no effect in some patients. Korean medicine treatments have been used in such patients, but few reports exist. Case Presentation: A 58-year-old female patient with CIPN reported symptoms of bilateral limb pain and tingling sensations as well as cold sensations in bilateral lower legs and hands, fatigue, and bilateral limb weakness. To reduce the patient's symptoms, we provided Korean medical treatment, including herbal medicine (Uchashinki-hwan), acupuncture, and moxibation. To evaluate the results of this treatment, we used a numeric rating scale (NRS), the manual muscle test (MMT), the National Cancer Institute Common Toxicity Criteria for Adverse Events (CTCAE), and the European Organization for Research and Treatment of Cancer quality-of-life questionnaire about CIPN (EORTC-QLQ-CIPN20). After 49 days of treatment, the NRS scores decreased for bilateral limb pain and tingling, for bilateral lower leg and hand cold sensation, and for fatigue. The MMT results for the upper and lower extremities were improved. CTCAE Grade and EORTC QLQ-CIPN20 score were also decreased. Conclusion: According to these results, Korean medicine treatment may be considered an effective treatment for CIPN. Prospective studies are needed in the future to confirm and expand these findings.
