This study was designed to evaluate the effect of the bee venom(BV) aqua-acupuncture on the neuronal activities of serotonergic(5-HT) system in the brainstem. After the BV aqua-acupuncture was applied on Chok-Samni(ST36) and the gluteal part(Blank locus) in rats, the number of Fos immunoreactive neurons was counted by using computerized image analyzing system. Also, the number of colocalization between 5-HT containing neurons Fos immunoreactive neurons were analyzed by using the double immunohistochemical technique. The results of the experiments were summarized as follows : 1.In almost every neucli, the Chok-Samni group and Blank locus group showed more increase in the number of Fos immunoreactive neurons than the control group. Especially, in Arc, DR, LC, RMg, Gi, PAG Rost and PAG LV, the Chok-Samni group showed more significant increase than the control group. Also, in PAG LV Mid and Arc, Chock-Samni group showed more significant increase than the Blank locus group. 2.In DR and PAG LV Mid, Chok-Samni group and the Blank locus group showed more significant increase in the number of colocalization between 5-HT containing neurons and Fos immunoreactive neurons than the control group after the BV aqua- acupuncture. Also, the Chok-Samni group showed more significant increase than the Blank locus group. Consequently, the BV aqua-aqupuncture increased more potent the number of Fos immunoreactive neurons and the activity of serotonergic neurons. Furthermore, the BV aqua-acupuncture was more effective on Chok-Samni than Blank locus group. These results indicate that the BV aqua-acupuncture is very effective therapy to control pain. The therapeutic effect of BV aqua-acupunture may associated with the endogenous modulatory system such as serotonin Those data from the study can be applied to establish the effective treatment of the BV for pain control in the clinical field.

In spite of the use of Bee Venom aqua-acupuncture in the clinics, the scientific evaluation of effects is not enough. Bee Venom aqua-acupuncture is used according to the stimulation of acupuncture point and the chemical effects of Bee Venom. The aims of this study is to investigate the analgegic effects of the Bee Venom aqua-acupuncture, through the change of writhing reflex and the change of c-fos in secondary neurons in the spinal cord. Materials and Methods : Pain animal model was used acetic acid method. The changes of writhing reflex of the mice which were derived pain by injecting acetic acid into the abdomen, after stimulating Bee Venom aqua-acupuncture on Chungwan(CV12) were measured. We used Fos immunohistochemical technique to study the neuronal activity in the spinal cord. Results : 1.Expression of c-fos in superficial dosal horn(SDH), nucleus proprius(NP) and neck of dorsal horn(N) on 6~9th thoracic spine decreased significantly at 2.5×10-4g/kg Bee Venom aqua-acupuncture, compared with saline-acetic acid group. 2.The numeral change of Fos-LI neurons on the NP, N, and ventral gray(V) on 6~9th thoracic spine, SDH on 9~11th thoracic spine, and SDH and V on 11~13th thoracic spine decreased significantly at Chungwan(CV12) Bee Venom aqua-acupuncture, compared with saline-acetic acid group. 3.The correlation between the numbers of writhing reflex and Fos-LI neurons in T6-13 segment was statistically statistically significant at Chungwan(CV12) Bee Venom aqua-acupuncture. Conclusion : This study shows that the Bee Venom aqua-acupuncture on Chungwan(CV12) decreases the numbers of Fos-LI neurons. As the analgegic effects of Bee Venom aqua-acupuncture is recognized. Bee Venom aqua-acupuncture treatment is expected for pain modulation. In order to use it in many ways. more researches are needed for the dose and stability of Bee Venom aqua-acupuncture.

Background/Aims: Endoscopic diagnosis of dysplasia or colitic cancer in patients with ulcerative colitis (UC) is more challenging than that of colorectal neoplasia in non-colitic patients. We aimed to evaluate the accuracy of the endoscopic diagnosis of “nonpedunculated” dysplasia or colitic cancer in UC patients. Methods: Ten endoscopists from four countries were surveyed using photographs of 61 histologically confirmed dysplastic or non-dysplastic lesions retrieved from the UC registry database of Asan Medical Center. The participants provided their assessment based on the given photographs and their intention to perform biopsy. Results: The overall diagnostic performance of the 10 participants is summarized as follows: sensitivity of 88.2% (95% confidence interval [CI], 84.3% to 91.5%), specificity of 34.8% (95% CI, 29.1% to 40.8%), positive predictive value of 63.0% (95% CI, 60.8% to 65.2%), negative predictive value of 70.2% (95% CI, 62.7% to 76.6%), and accuracy of 64.6% (95% CI, 60.7% to 68.4%). The interobserver agreement on the intention to perform a biopsy was poor (Fleiss kappa=0.169). Of the three endoscopic characteristics of the lesions, including ulceration, distinctness of the borders, and pit patterns, only neoplastic pit patterns were significantly predictive of dysplasia (odds ratio, 3.710; 95% CI, 2.001 to 6.881). The diagnostic sensitivity and specificity of neoplastic pit patterns were 68.2% (95% CI, 63.0% to 73.2%) and 63.3% (95% CI, 57.3% to 69.1%), respectively. Conclusions: Diagnostic performance based on the endoscopist’s intention to perform a biopsy for nonpedunculated potentially dysplastic lesions in UC patients was suboptimal according to this survey-based study.

<P>Abstract</P><P><B><I>Background/Aims:</I></B> β<SUB>2</SUB>-Microglobulin (β<SUB>2</SUB>-M) is a surrogate marker of middle-molecule uremic toxins and is associated with mortality in chronic hemodialysis patients. However, the impact of serum β<SUB>2</SUB>-M levels on mortality in peritoneal dialysis (PD) patients is uncertain. The purpose of this study was to examine the association of serum β<SUB>2</SUB>-M levels with all-cause mortality in PD patients. <B><I>Methods:</I></B> A total of 771 PD patients were selected from the Clinical Research Center registry for end-stage renal disease cohort in Korea. Patients were categorized into 3 groups by tertiles of serum β<SUB>2</SUB>-M levels. The primary outcome was all-cause mortality. <B><I>Results:</I></B> The median value of serum β<SUB>2</SUB>-M was 23.6 mg/l (interquartile range 14.8-33.4 mg/l), and the median follow-up period was 39 months. The Kaplan-Meier analysis showed that the all-cause mortality rate was significantly different according to tertiles of serum β<SUB>2</SUB>-M in PD patients (p = 0.03, log-rank). Multivariate Cox proportional analysis showed that the hazards ratio for all-cause mortality was 1.02 (95% CI 1.01-1.04, p = 0.006) per 1 mg/l increase in β<SUB>2</SUB>-M after adjustment for multiple confounding factors that relate to malnutrition and inflammation marker. However, serum β<SUB>2</SUB>-M was not associated with all-cause mortality after adjustment for residual renal clearance. <B><I>Conclusions:</I></B> These results are supportive of the potential role of the serum β<SUB>2</SUB>-M level as a predictor of mortality in PD patients.</P><P>© 2015 S.
