  • Background: Systemic or intrathecal administration of gabapentin has been shown to reverse various pain states. However, until now, the effect of intracerebroventricular (ICV) gabapentin to noxious stimuli has not been reported. The authors' aim of this study was to determine the effect of ICV gabapentin on the inflammatory nociceptive model, formalin test, in rats. Methods: ICV catheters were implanted under halothane anesthesia. For the nociceptive test, $50{\mu}l$ of 5% formalin was subcutaneously injected into the hindpaw. The effect of ICV gabapentin, administered 10 min before formalin injection, were examined on flinching, mean arterial pressure and heart rate evoked by a injection of formalin. Results: Injection of formalin into the paw resulted in a biphasic flinching and cardiovascular response. ICV gabapentin produced a dose-dependent suppression of the flinching and mean arterial pressure response during phase 1. In contrast, in phase 2, ICV gabapentin did not attenuate the pain behavior. ICV gabapentin did not affect on the baseline mean arterial pressure and heart rate. Conclusions: ICV gbapentin was effective for the acute noxious stimulus but it had no effect on the facilitated states induced by tissue injury.

  • Objectives: This study aimed to investigate the preventive effect of red ginseng (RG) on 5-fluorouracil (5-FU)-induced side effects focusing on myelosuppression. Methods: Rats (n = 50) were divided into five groups, nave, control (ip, 5-FU injection of 150 mg/kg), and RG pre-treatment (po, 25, 50 and 100 mg/kg for 5 days before 5-FU injection). On the $7^{th}$ day after 5-FU injection, we evaluated the effects using peripheral hematological parameters, colony-forming assay, cytokine levels and histopathological finding. Results: The peripheral white blood cell and the differential count were dramatically suppressed by 5-FU, while RG (50 and 100 mg/kg) treatment significantly improved total white blood cell, neutrophil, lymphocyte and platelet counts. Also, RG (100 mg/kg) pre-treatment significantly increased the number of CFU-GM colony compared with the control group. RG pre-treatment also ameliorated the histopathological damage in bone marrow, spleen, stomach and small intestine tissue. Conclusions: These results demonstrate that Korean RG has preventive effects against 5-FU-induced myelotoxicity and gastrointestinal damage.

  • Objective: To assess the safety of Brucea javanica and Cantharidin combined with chemotherapy in treating patients with non-small-cell lung carcinoma. Method: A consecutive cohort of patients with NSCLC were divided into four groups: experimental group A treated with Brucea javanica injection combined with chemotherapy; experimental group B with Cantharidin injection combined with chemotherapy; experimental group C treated with Brucea javanica and Cantharidin injection combined with chemotherapy; and the control group receiving only chemotherapy. After more than two courses of treatment, safety, quality of life and side effects were evaluated. Results: The incidences of myelosuppression in groups A, B and C were lower than that in Control group (p<0.05), but without significant differences among A, B and C. Adverse effects on the gastrointestinal tract also were lower than in controls (p<0.05) without variation amnog the combined treatment groups. Conclusions: Brucea javanica or Cantharidin combined with chemotherapy could in both cases improve quality of life in our cohort of NSCLC patients without any increase in toxicity. However, further clinical experiments should be conducted to evaluate the efficacy of Brucea javanica and Cantharidin combined with chemotherapy for patients with NSCLC.

  • Objective: Globozoospermia is observed in <0.1% of male infertile patients. The aim of this study is to report the successful clinical outcome in man with globozoospermia. Design: A case report. Method: A 36-year-old man and 32-year-old partner visited our fertility center with 6 years infertility duration. The semen analysis revealed globozoospermia combined with oligozoospermia which was stained with Diff-Quick method. ICSI (Intracytoplasmic sperm injection) was performed on 12 matured oocytes. Result: 5 injected oocytes were fertilized normally. 5 embryos were transferred on day 3 after oocyte retrieval. The patient became pregnant and delivered a healthy boy at 39 weeks of gestation. Conclusion: In case of globozoospermia, it has a low fertilization rate even though ICSI method is used. The favorable technique is still needed to increase the fertilization rate.

  • Background: Ultrasound-guided caudal epidural injection (CEI) is limited in that it cannot confirm drug distribution at the target site without fluoroscopy. We hypothesized that visualization of solution flow through the inter-laminar space of the lumbosacral spine using color Doppler ultrasound alone would allow for confirmation of drug distribution. Therefore, we aimed to prospectively evaluate the usefulness of this method by comparing the color Doppler image in the paramedian sagittal oblique view of the lumbosacral spine (LS-PSOV) with the distribution of the contrast medium observed during fluoroscopy. Methods: Sixty-five patients received a 10-mL CEI of solution containing contrast medium under ultrasound guidance. During injection, flow was observed in the LSPSOV using color Doppler ultrasonography, following which it was confirmed using fluoroscopy. The presence of contrast image at L5-S1 on fluoroscopy was defined as "successful CEI." We then calculated prediction accuracy for successful CEI using color Doppler ultrasonography in the LS-PSOV. We also investigated the correlation between the distribution levels measured via color Doppler and fluoroscopy. Results: Prediction accuracy with color Doppler ultrasonography was 96.9%. The sensitivity, specificity, positive predictive value, and negative predictive value were 96.7%, 100%, 100%, and 60.0%, respectively. In 52 of 65 patients (80%), the highest level at which contrast image was observed was the same for both color Doppler ultrasonography and fluoroscopy. Conclusions: Our findings demonstrate that color Doppler ultrasonography in the LS-PSOV is a new method for determining whether a drug solution reaches the lumbosacral region (i.e., the main target level) without the need for fluoroscopy.

  • The purpose of the present study is to determine the role of muscarinic cholinergic receptors of posterior hypothalamus in the central blood pressure regulation when respiration is controlled. In anesthetized and artificially ventilated rats, vasodepressor response was evoked by injection of L-glutamate(10 nmol) neuroexcitatory amino acid into the posterior hypothalamic area. The injection of $carbachol(0.5{\sim}8\;nmol)$ into the same area induced dose-dependent vasodepressor and bradycardic responses. Pretreatment with atropine(4 nmol) completely blocked the vasodepressor response to carbachol(2 nmol). In contrast, in spontaneously breathing rats, the injection of carbachol(8 nmol) into the posterior hypothalamic area induced the vasopressor and tachycardic responses. These results suggest that the muscarinic cholinergic receptors in the posterior hypothalamic area primarily play an inhibitory role in the central regulation of blood pressure and heart rate.

  • According to the North Korean documents , North Korean government have emphasized the development of the Koryo medicine (traditional korean medicine) and encouraged the combination of the Koryo and the modern medicine. It is regarded that this attitude arose from the ruler's will toward independency in the medical field and at the same time the lack of modern medical resources . Combinations of the Koryo medicine and the modern medicine in the clinical textbooks are classified as follows: first, mixed medication of the Koryo and the modern medicine. Second, combination of the traditional acupuncture(or moxibustion) and the medication of modern medicines. Third, injection of modern medicines at acupoints. Forth, an intramuscular or an intravenous injection of the Koryo medicine. Fifth, anesthesia using Koryo medicine. Sixth, simple surgery at the acupoints. Lastly, combination of injection and the traditional therapy(eg. acupuncture, moxibustion and cupping) Despite of many achievements in the field of combined medical treatment, recent economic failure and severe famine for several years caused collapse of the health care delivery system in North Korea, and it is hard to find combined practices actually.

  • Background: Injection therapy around the distal biceps tendon insertion is challenging. This therapy may be indicated in patients with a partial distal biceps tendon tear, bicipitoradial bursitis and tendinopathy. The primary goal of this study was to determine the accuracy of manually performed injections without ultrasound guidance around the biceps tendon. Methods: Seven upper limb specialists, two general orthopedic specialists, and three orthopedic surgical residents manually injected a cadaver elbow with acrylic dye using an anterior and a lateral infiltration approach. After infiltration the cadaveric elbows were dissected to determine the location of the acrylic dye. Results: In total, 79% of the injections were localized near the biceps tendon. Of these injections, 20% were localized on the radius near the bicipitoradial bursa. In total, 53% of the performed infiltrations were injected by anterior and 47% by lateral approaches. Of the injections near the distal biceps (79%), 47% were injected by an anterior and 53% by a lateral approach. Of the injections on the radius (20%), 33% were injected by anterior and 67% by lateral approach. Of the inaccurate injections (21%), 75% were injected anterior and 25% lateral. Conclusions: Manual infiltration without ultrasound guidance for distal biceps pathology lacks accuracy. We therefore recommend ultrasound guidance for more accurate infiltration.

  • The aim of this study was to achieve optimal portal phase while reducing contrast medium by applying weight-based dose protocol compared to standard fixed dose protocol to performing of pediatric abdominal CT examination. Discovery 750HD (General Electric Medical Systems, Milwaukee, USA) was used, and a total of 167 children consisting of 85 men and 82 women under the age of 18 were studied. The group in which the 300 mgI/ml(Xenetix, Guerbet, France) contrast medium was fixedly injected at twice body weight and the group injected with physiological saline while gradually decreasing the injection amount by 10% while applying the weight-based protocol were distinguished. Also, the CT number and SNR of abdominal organs were compared and evaluated while changing the scan delay time. Subjective image quality of enhancement and beam-hardening artifacts of around the heart was assessed with five-point criterion. The group adapted weight-based protocol with 20% reduction in contrast medium was most similar in contrast enhancement in the group with fixed injection at twice body weight. Furthermore, the group with a delay time of 20% had the highest contrast enhancement effect, and the difference in CT attenuation coefficient from the group scanned immediately after injection of the contrast media. Therefore, the appropriate delay time after injection of the contrast agent increased the contrast enhancement of the parenchymal organ. In addition, the weight-based injection protocol with normal saline reduced artifacts around the heart, and the effect of contrast enhancement could be maintained. In conclusion, it is possible to reduce dosage of contrast media through the application of weight-based injection protocols and appropriate latency, and to characterize optimal portal phase imaging on pediatric abdominal CT.

  • IK can downregulate interferon-gamma-induced major histocompatibility complex (MHC) class II expression through the MHC class II transactivator, which suggests that IK can inhibit the interactions between immune cells. We delivered adeno-associated virus serotype 2 (AAV2) encoding the genes for truncated IK (tIK) or green fluorescent protein (GFP) to DBA1/J mice via intravenous injection. Seven weeks after injection, collagen-induced arthritis was induced in the AAV2-treated mice. AAV2-tIK injection reduced the severity of arthritis and the percentage of pathogenic Th17 cells compared with AAV2-GFP injection. These results suggest a novel gene therapy strategy for treatment of inflammatory arthritis.
