Objective : The purpose of this study was to verify the appropriateness of ovariectomized rats as the osteoporosis animal model. Methods : Twelve female Sprague-Dawley rats underwent a sham operation (the sham group) or bilateral ovariectomy [the ovariectomy (OVX) group]. Eight weeks after operations, serum biochemical markers of bone turnover were analyzed; osteocalcin and alkaline phosphatase, which are sensitive biochemical markers of bone formation, and C-terminal telopeptide fragment of type I collagen C-terminus (CTX), which is a sensitive biochemical marker of bone resorption. Bone histomorphometric parameters and microarchitectural properties of 4th lumbar vertebrae were determined by micro-computed tomographic (CT) scan. Results : The OVX group showed on average 75.4% higher osteocalcin and 72.5% higher CTX levels than the sham group, indicating increased bone turnover. Micro-CT analysis showed significantly lower bone mineral density (BMD) (p=0.005) and cortical BMD (p=0.021) in the OVX group. Furthermore, the OVX group was found to have a significantly lower trabecular bone volume fraction (p=0.002). Conclusion : Our results showed that bone turnover was significantly increased and bone mass was significantly decreased 8 weeks after ovariectomy in rats. Thus, we propose that the ovariectomized rat model be considered a reproducible and reliable model of osteoporosis.
Lumbopelvic stabilization exercise has become the most popular treatment method in lumbar rehabilitation since its effectiveness was shown in some aspects of pain and disability. The abdominal drawing-in maneuver (ADIM) has been extensively implemented to promote lumbopelvic stability. However, performing ADIM correctly is difficult even for healthy subjects, and it is time consuming to train people in ADIM. Thus, the purpose of this study was to compare abdominal muscle [rectus abdominalis (RA), external oblique (EO), and transverse abdominis/internal oblique (TrA/IO)] activity during lumbopelvic stabilization exercises (ADIM only, ADIM with a ball, maximum exhalation only, and maximum exhalation with a ball) performed in a supine position with feet against a wall. Fifteen healthy subjects were recruited for this study. Surface electromyography was used to measure abdominal muscle activity during lumbopelvic stabilization exercises. A one-way repeated-measures analysis of variance was used to determine the statistical significance of RA, EO, and TrA/IO muscle activity during four lumbopelvic stabilization exercises. Both-side TrA/IO muscle activity was significantly greater with maximum exhalation with a ball than with ADIM only or ADIM with a ball (p<.008). The results of this study suggest that maximum exhalation with a ball can be used as an effective lumbopelvic stabilization exercise to increase TrA/IO muscle activity in healthy subjects.

The purposes of this study were to compare core muscle activities with and without the use of Pilates resistive equipment during bridging exercises and to investigate the efficacy of a Pilates device. Fourteen healthy individuals (6 males, 8 females) between 20 to 26 years of age were examined. They were engaged in a bridging exercise with and without a magic circle. Three consecutive repetitions of each exercise were performed. Surface electromyography (sEMG) was used to measure the electrical activities of the right side internal oblique, the adductor longus, the multifidus, and the gluteus maximus muscles. Normalized EMG activities were compared using a paired t-test and the level of significance was set at =.05. The results showed that the EMG activities of the internal oblique (p=.0078), the adductor longus (p=.0007), and the gluteus maximus (p=.0001) muscles were significantly higher when using the magic circle during the Pilates bridging exercise. Also, statistically significant change existed in the multifidus muscle (p=.0106). The bridging exercise, combined with hip adduction using the magic circle, may enhance core stabilization. Therefore, using a magic circle during hip adduction combined with bridging exercise may be recommended usefully for individuals wanting to strength the core muscles. Further research is needed to access the nature of motor control of the Pilates mat exercises and to deliver exercise intervention for lower back pain patients.

Objective : The purposes of this study were to evaluate the prevalence, types, and locations of Modic changes (MCs) in the thoracic spine in a large number of subjects, and to investigate the relation between the distributions of MCs and disc herniations (DHs) in the thoracic spine. Methods : Two experienced musculoskeletal radiologists assessed the presence of MCs and DHs by consensus in the thoracic MRIs of 144 patients with non-specific back pain. Patient ages ranged from 22 to 88 years (mean=$53.3{\pm}14.66$ years), and 72 were female (50%). The prevalence, distribution, relation of MCs and DHs was recorded. Results : MC was observed in 8 of the 144 patients (5.6%) and 10 of 1728 segments (0.58%). The most common MC was type II. Of the 8 patients exhibiting MC, 6 had type II (75.0%), and 2 had mixed MCs (type I/II or type II/III). MCs were distributed mainly at the mid-thoracic level (from T5/6 to T9/10). DH was detected in 18 patients (12.5%), 36 of 1728 segments (2.1%). Of the 10 segments exhibiting MC, 5 had DHs at the same level (50.0%). Accordingly, DH was strongly associated with MC (p=0.000). Conclusion : A low prevalence of MC was observed in the thoracic spine, and type II MC predominated. The low prevalence of MC in the thoracic spine suggests that it was caused by a relative lack of mobility as compared with the cervical and lumbar spines. And DHs were found to be strongly associated with MCs even in the thoracic spine.

Primary lung cancer is unusual in children; the squamous cell variant is extremely rare. Lung cancer is classified by histologic types into small-cell lung cancer, non-small cell lung caner, carcinoid, mucoepidermoid carcinoma, and adenoid cystic carcinoma. Furthermore, non-small cell lung cancer is subclassified into adenocarcinoma, large-cell carcinoma, and squamous cell carcinoma. The incidence of lung cancer is influenced by smoking, especially in squamous cell carcinoma, and large cell carcinoma. The present treatments for these tumors are chemotherapy, radiation therapy, and surgical resection depending on their histologic types or stages, but yield very poor survival rates. In this article, we report a case of basaloid squamous cell lung carcinoma in an 11-year-old boy who had symptoms of both leg weakness and back pain radiating to both legs. We confirmed the primary lung carcinoma cells by percutaneous transthoracic needle biopsy. The metastatic carcinoma cells were identified at the bone marrow and lumbar spine. We treated with a combination chemotherapy and radiation therapy. However, he expired 4 months after the onset of disease.

Objectives: The aim of this study was to analyse the domestic trends of Chuna treatments techniques in Korean literature. Methods: We searched the clinical trials on Chuna treatments through both electronic search(used keyword 'chuna') and hand search in 3 Korean web databases(OASIS, NDSL, RISS) and 4 related journals(The Journal of Korea CHUNA Manual Medicine for Spine & Nerves, Journal of Oriental Rehabilitation Medicine, The Journal of Korean Acupuncture & Moxibustion Society, Journal of Korean Medicine Society). All relevant clinical trials were selected and extracted to be analyzed according to their published year, journals, types of study, used techniques. Results: The number of the clinical studies tends to increase every year. The studies on Chuna treatments were mainly published in The Journal of Korea Chuna Manual Medicine for Spine & Nerves. In case of types of study, case reports and case series were predominant. The most frequently adopted techniques of Chuna in studies were flexion distraction technique for lumbar spine and JS supine position cervical spine distraction. Conclusions: Through the results of this study, we hope that the more qualitative education could be conducted by strengthening the techniques which often used. Also analysis of the reason of rarely used techniques should be conducted and the modification or developing techinques should be followed as a counter measures. As applying more rigorous methodology, more qualitative evidence based Chuna studies should be conducted in future clinical research.
We have experienced 27 cases of primary medistinal tumors and cyst from April, 1986 to April 1996. At Masan Samsung General Hospital. The results of the anslysed were as follows 1. Of 27 medistinal tumors and c,pests, 9 patients were male and 18 patients were female(m : f= 1 : 2) 2. The most common chief complaint was chest discomfort or pain(8 cases 30 %) and 17 patients(63%) were asymptomatic. 3. The most common primary medistinal tumor was Neurogenic tumor in 9 cases(33 %) followed by Thymoma in 7 cases(26 %), teratoma in 6 cases(22 %) 4. The incidence of malignancy of all case was 3 cases(11 %), all cases were symptomatic and the most common malignancy was malig. thymoma(3 cases,43 %) 5. The anterior mediastinum was the most common tumor location with 15 cases(56 %) followed by posterior 11(41 %) and middle mediastinum 1(4 %). Anterior mediastinum tumors were predominantly thymomas and teratoma and posterior mediastinal tumors were neurogenic tumors 6. Complete removal of tumor was achieved in 26 cases(96 %) and open biopsy was done on 1 case 7. Postoperative complications were continued lumbar shunt drainage in 1 case and wound infection in 1 case 8. There was no case of postoperative mortality and good clinical course in surgically completely rejected cases
The purpose of this study is to establish the analgesic effects of electroacupuncture for Korean native goat. Electroacupuncture was applied to the 6 Korean native goats. In 3 of them, rumenotomy was performed, and in the other 3, laparotomy was done. The analgesic induction time was 15 to 30 minutes. The acupoints used were Tian-ping (Celestial Peace, GV-5), Bai-hui (Hundred Meetings, GV-20), left 13th thoracic nerve and left 3rd lumbar nerve. Electroacupuncture was performed in lateral recumbency. Needles were inserted 1-2 cm deep, and connected to the electroacupuncture apparatus. The electrical stimulation condition was 30 Hz and 2-6 volts. Initially, the voltage of analgesia mode was maximized in each channel. And, the output was slowly reduced to the critical point that goats could tolerate without obvious discomfort or pain. Surgical operation was done successfully under electroacupuncture analgesia in 6 Korean native goats. In addition, the changes of temperature, heart rate and respiratory rate were studied during acupuncture analgesia. For 3 months after surgery, no experimental animals showed clinical problem in 6 Korean native goats.
We recently demonstrated that bee venom (BV) injection into acupoint (i.e. Zusanli) produced more potent anti-inflammatory and antinociciptive effect in Freunds adjuvant induced rheumatoid arthritis (RA) model as compared with that of non-acupoint injection(i.e back). However, the precise components underlying BV-induced antinociceptive and/or anti-inflammatory effects have not been fully understood. Therefore, we further investigated the anti-arthritic effect of BV after extracting the whole BV according to solubility (water soluble: BVA, ethylacetate soluble: BVE). Subcutaneous BVA treatment (0.9 mg/kg/day) into Zusanli acupoint was found to dramatically inhibit paw edema and radiological change (i.e. new bone proliferation and soft tissue swelling) caused by Freunds adjuvant injection. In addition, the increase of serum interleukin-6 by RA induction was normalized by the BVA treatment as similar with that of non-arthritic animals. On the other hand, BVA therapy significantly reduced arthritis induced nociceptive behaviors (i.e., nociceptive score for mechanical hyperalgesia and thermal hyperalgesia). Furthermore, BVA treatment significantly suppressed adjuvant induced Fos expression in the lumbar spinal cord at 3 weeks post-adjuvant injection. However, BVE treatment (0.05 mg/kg/day) has not any anti-inflammatory and anti-nociceptive effect on RA. Based on the present results, we demonstrated that BVA might be a effective fraction in whole BV for long-term treatment of RA-induced pain and inflammation. However, it is clear necessary that further fraction study about BVA was required for elucidating an effective component of BVA.
