The vanilloid receptor type-1 (VR1) is a nonselective cation channel activated by capsaicin and can be act as mediator of chemical and physical stimuli that elicit pain. The presence of VR1 in the dorsal root, trigeminal and nodose ganglia has been firmly established, but it unclear in the mouse intestinal wall. The distribution of VR1 receptors in mouse afferent neurons innervating the intestinal tract was investigated by immunohistochemistry. Also small and large intestines were dual-labelled with antibody for VR1 and marker for interstitial cells of Cajal (c-kit). VR1-immunopositive cells were localized on fine fibers in myenteric plexus and expressed weakly myenteric ganglia. The majority of VR1-immunopositive fibers are not colocalized with or apposed to c-kit positive interstitial cells of Cajal. Also electrophysiologically capsaicin had no effect on cultured interstitial cells of Cajal. It is concluded that VR1-immunoreactive intestinal nerves are mainly distributed in myenteric plexus of murine intestinal wall, and vanillod may be not directly related to interstitial cells of Cajal in regulation of intestinal motility.

OBJECTIVE: Premenstrual syndrome (PMS) is a disease with specific psychologic and physical symptoms on luteal phase. Its incidence is variable in 20~80%, but its cause is not definitely proved. Because progesterone and estrogen affect the balance of the body mineral, the alteration of progestorone and estrogen in the patients with PMS may effect the imbalance of tissue mineral, that can induce the specific symptoms of PMS. This study examines the relationship between symptoms of PMS and mineral count by tissue mineral test. METHODS: Women who volunteered for the tissue mineral test completed MMDQ questionnaire and checked blood test for Ca, Mg, Na, K, Cu, Zn. The tissue mineral test used the hair not treated within 3 weeks and not washed within 3 hours. The hair was send to TEI for the analysis. We used SPSS (14.0) for statistical analysis. RESULTS: The MMDQ score of the normal Mg group is significantly higher than the high Mg group (22.5+/-17.8 vs. 13.9+/-11.1), and the behavioral disorder score of the normal Na group is significantly lower than the low Na group (2.2+/-1.7 vs. 3.4+/-2.2). The MMDQ score of the normal Cu group is significantly lower than abnormal group (15.7+/-11.9 vs. 24.9+/-16.9). CONCLUSIONS: Total score of MMDQ showed difference according to magnesium and copper concentrations in tissue, and scores of behavioral disorder was affected by sodium concentration of tissue. Additional study about cause and effect relationship is required.

In this study, we examined chewing frequency, eating rates, and food consumption volume according to the body mass index of male and female college students. Twenty-five male college students were divided into a normal weight male group (<23 body mass index, n=14) and an obese male group (> or =23 body mass index, n=11). Twenty-five female college students were divided into a normal weight female group (<23 body mass index, n=21) and an obese female group (> or =23 body mass index, n=4). Subjects were provided with abundant fried rice and allowed to consume it at their own pace. Chewing frequency, total mealtime, rate of eating, consumption volume, calorie intake, and the amount of one bite were measured. There were no significant differences in chewing frequency, total mealtime, rate of eating, consumption volume, calorie intake, and the amount of one bite between the normal and obese male groups. There were also no significant differences in chewing frequency, consumption volume, calorie intake, and the amount of one bite between the normal and obese female groups. However, the obese female group had a significantly shorter mealtime and significantly higher eating rate compared with the normal group. Thus, our study suggests that females who eat a meal for a longer time may reduce their food intake, consequently inducing body weight loss.

Placement of a pulmonary artery catheter is associated with various complications, including catheter knotting. Fluoroscopy can be used to visualize and confirm catheter knotting. Transesophageal echocardiography is readily available to detect knot formation in the operating room or intensive care unit. We present a case in which pulmonary artery catheter knotting was detected by transesophageal echocardiography. This method may be useful in the operating room or in the intensive care unit to identify the presence and location of catheter knotting.

Adenofibromas of the uterine cervix, which are classified as benign tumors of mixed epithelium and mesenchymal cells, are extremely rare. Most common symptom is usually abnormal genital bleeding. It is very difficult to diagnose preoperatively. Recommended method of treatment is total hysterectomy, because it usually recurs. We experienced a case of adenofibroma of the uterine cervix with increased CA125, so report it with a review of the literature.

OBJECTIVE: To evaluate the clinical efficacy of radiofrequency myolysis which is new developed uterine preserving management of myoma. METHODS: 17 patinets (27 myomas) who done radiofrequency myolysis between Oct. 2004-Dec. 2004 were participated this study. Preoperatively, Hemoglobin and subjective symptoms were checked and size of myoma was checked using ultrasonogram or computed tomogram (CT). Radiofrequency was applied to myoma for 10 to 40 minutes per one. Follow up sonogram or CT were done 7 days, 1 month, 2 month and 3 month after myolysis. RESULTS: Average age of patients was 42.7+/-8.6 (yr) and average size of myoma was 4.9+/-2.3 cm. We followed 27 nodules. After 3 months, reduction of volume was observed 65%, from 30% to 94%. 3 nodule, which was followed only 2 months, reduced by 46%. About subjective symptoms, 80% reduction was reported after 3 months (50-100%). Menorrhagia reduced 91% in average and pressure symptoms reduced 71% in average. No severe complication like bowel injury, bladder injury, infection and pulomonary embolism was not observed. Serious vaginal bleeding was reported for 3 patients, and their hemoglobin decreased from 10.8 mg/dL preoperatively to 8.7 mg/dL postopertively. CONCLUSION: Radiofrequency myolysis decreased myoma 65% in average. No serious complication were reported.

OBJECTIVE: The aim of this study was to investigate the changes in hormone receptors of myoma cells and volume decrement of myoma after radiofrequency myolysis. METHODS: From 2005 January to 2006 January, thirty patients who have had high-frequency myolysis were included in this study. Needle aspiration biopsy was done at the central portion of myoma pre- and 6 months post-operation. Radiofrequency myolysis were done for 20 minutes until discoloration of myoma was accomplished to 80%. The stain intensity of estrogen receptor (ER) and progesterone receptor (PR) was classified into "negative", "trace", "weak", "moderate" and "strong". RESULTS: The volume decrement was 96.4% in the group that showed trace to week stain intensity (under 50% stain intensity), but it decreased to 66.6% in the group that showed strong stain intensity (over 50%, moderate to strong)(P<0.05). ER showed moderate to strong positive response in 79% of patients before operation, but it showed negative to week response in 83% of patients after the operation. Also, PR showed moderate to strong positive response in 80% of patients before operation, but it showed negative to week response in 86% of patients after the operation. CONCLUSIONS: To coagulate entire myoma, we suggested that controlling the intensity of operation by lengthening the time or expanding the extent of operation was more effective in treatment, because the volume decrement of myoma was larger in case that ER and PR was under 50% before the operation.
