BACKGROUND: Endotoxins play important roles in the pathophysiologic alterations associated with sepsis so the authors examined the effects of hydroxocobalamin, NW-nitro-L-arginine-metyl ester (L-NAME) and aminoguanidine on thiopental-induced contractile responses of lipopolysaccharide (LPS)-treated and control rat aortic rings. METHODS: Aortic ring preparation was obtained from LPS-treated (1.5mg/kg, i.p. for 18h) rats. Cumulative doses of thiopental (10-4~3x10- 3M) were added to construct contraction response curves. Hydroxocobalamin (10-5M), L-NAME (10-6M) or aminoguanidine (10-6M) were added as NO scavenger or as NOS inhibitors. Contraction curves by cumulative doses of thiopental (10-4~3x10-3M) were remeasured after treatment of NO scavenger or NOS inhibitors. Statistical significances (p<00.05) were analyzed according to data characteristics by Student's t-test, paired t-test or ANOVA. RESULTS: The vascular responses of cumulative thiopental (10-4~3x10 3M) administration were dose- dependent contraction and LPS-treated rat was less contracted (p<00.05). There was significant increment on vascular contraction induced by thiopental after hydroxocobalamin pretreatment in LPS-treated rat (p<0.05), in spite of L-NAME, aminoguanidine pretreatment was failed to increase contractile forces in control and LPS-treated rats. CONCLUSIONS: From these results, viewed from maintenance of vasomotor tone in septic state, it is suggested that hydroxocobalamin may be candidate for vasopressor during usual induction of general anesthesia.

A nineteen year-old boy with progressive enlargement of the joints and distal extremities, clubbing, coarse facial features and hyperhidrosis was investigated. In physical examination, thickening of the scalp with furrowing (cutis verticis gyrata) and greasy thickening of skin (pachyderma) was prominent. His endocrine profile was normal. Radiological studies demonstrated bilateral symmetrical periosteal new bone formation with acroosteolysis and incidental microadenoma of pituitay gland. After extensive investigation to exclude systemic and endocrine causes, the patient was diagnosed as pachydermoperiostosis (PDP). PDP is a rare syndrome manifested clinically by finger clubbing, extremity enlargement, hypertrophic skin changes, and periosteal bone formation. The pathogenesis of the disorder has not been clarified though few endocrine abnormalities were seen. To aware of these clinical phenotype would help to differentiate PDP from acromegaly.

this study was undertaken to compare the riboflavin status of rural women with different physical activity intensity and to determine factors influencing biochemical fiboflavin status. The study was carried out over three different farming seasons : planting (June), harvest(October) and interim(February) in two rural regions of Korea. One was a traditional farming region, the other a commercial farming region with heavier work intensity. Twenty women in the traditional region and eighteen women in the commercial region were involved. The intensity of physical activity was determined by a daily activity record. Body composition was assessed by bioelectrical impedence. Dietary riboflavin intake was measured by the food frequency method. Riboflavin biochemical status was assessed by erythrocyte glutathione reductase activity coefficient (EGR AC) and ruinary riboflavin excretion. The results from the EGR AC and urinary riboflavin excretion during the period showed the overall riboflavin status of the commercial farming women was significantly worse than that of the traditional farming women(EGR AC p<0.0001, urinary riboflavin excretion p<0.05). The traditional farming group had about 40% with risk of riboflavin deficiency, whereas the commercial farming group had about 70%. Overall mean nutrient intake was not significantly different between the two groups, however, overall mean percent lean body mass representing long term physical activity was significantly higher in the commercial farming group (<0.005). It appears that the biochemical riboflavin status of traditional farming women was significantly influenced by riboflavin intake and crude nitrogen balance while the biochemical riboflavin status of the commercial farming women was significantly influenced by riboflavin intake and percent of lean body mass over the three seasons.

Chronic perineal pain is an often encountered problem, which produces a great degree of functional impairment and frustration to the patient and a challenge to the treating physician. The reason for this problem is that the region contains diverse anatomic structures with mixed somatic, visceral and autonomic innervations affecting bladder and bowel control and sexual function. A blockade of nociceptive and sympathetic supply to the perineal region, supplied through the ganglion impar has been shown to benefit patients with chronic perineal pain. Several options to this block have been described that chemical neurolysis, radiofrequency ablation etc. Although the analgesic effect of Botulinum toxin type A (BoNT-A) has long been considered secondary to its action for muscle relaxation, BoNT-A also affects the release of the neurotransmitters that are involved in pain perception. We describe a patient who was successfully given ganglion impar block with BoNT-A.

Mutation in the p53 suppressor gene is the most common genetic alteration found in human cancers including primary brain tumors. Ki-67 labeling index(LI) is known to be a marker of proliferating activity. The purpose of this study was to verify whether an immunohistochemical expression of p53 antibody and Ki-67 LI could be related to different clinicopathologic parameters including histologic grade, size, invasiveness and recurrence of the brain tumors. Materials were based on the 147 surgically resected brain tumors during the last two years. Of the 147 brain tumors, there were 35 astrocytic tumors, 35 meningiomas, 10 oligodendrogliomas, 7 craniopharyngiomas, 5 dysembryoplastic neuroepithelial tumors, 4 medulloblastomas, 5 ependymomas, 23 pituitary adenomas, 9 schwannomas, and 14 other brain tumors. The p53 expression and Ki-67 LI were higher in malignant brain tumors including astrocytic tumors, medulloblastoma, PNET and gliosarcoma. The p53 positivity was correlated with histologic grades and tumor recurrence. The brain tumors with a high Ki-67 LI(>6%) also showed a close relationship to a higher histologic grading, radiological invasiveness and recurrence. There was no evident correlation with the age and tumor size with p53 expression and Ki-67 LI. These results suggest that p53 overexpression and high proliferation potential of the tumor cells are associated with the higher histologic grade and aggressive clinical course in the central nervous system tumors.

BACKGROUND: Recent studies revealed that inhalational anesthetics (IA) attenuate NO production. But the hemodynamic changes produced by IA in septic syndrome patient are still sufficient to threaten patient, surgeon and anesthesiologist. So we examined which IA is proper to maintain vascular contractile force and evaluated the effects of NOS inhibitors on contractile force of septic rat aorta under IA. METHODS: Aortic ring preparation was obtained from LPS-treated (1.5 mg/kg, i.p. for 18h) rats. The development of sepsis was confirmed by iNOS activity and iNOS expression using RT-PCR. Contractile responses of aorta to phenylephrine admministation in the presence or absence of halothane, enflurane and isoflurane were evaluated. We also evaluated the effects of NOS inhibitors, one is NG-nitro-L-arginine methyl ester (L-NAME) and the other is aminoguanidine. Statistical significances (p<0.05) were analyzed according to data characteristics by unpaired t-test and paired t-test. RESULTS: The contractile responses to phenylephrine admministration were attenuated in LPS-treated rings. Isoflurane, even at the dose of 2 MAC, didn't affect the contractile response while both halothane and enflurane decreased the contractile response even at the dose of 1 MAC. The potentiation of contractile responses by NOS inhibitors were not affected during administeration of IA. CONCLUSIONS: From these results, it is suggested that isoflurane is the safest inhalational anesthetic and NOS inhibitors, especially L-NAME, may be very useful in the therapy of septic shock patients during general anesthesia.

PURPOSE: To evaluate the outcome of ductal carcinoma in situ (DCIS) patients who underwent surgery followed by radiation therapy (RT). MATERIALS AND METHODS: We retrospectively reviewed 106 DCIS patients who underwent surgery followed by postoperative RT between 1994 and 2006. Ninety-four patients underwent breast-conserving surgery, and mastectomy was performed in 12 patients due to extensive DCIS. Postoperative RT was delivered to whole breast with 50.4 Gy/28 fx. Tumor bed boost was offered to 7 patients (6.6%). Patients with hormonal receptor-positive tumors were treated with hormonal therapy. RESULTS: The median follow-up duration was 83.4 months (range, 33.4 to 191.5 months) and the median age was 47.8 years. Ten patients (9.4%) had resection margin <1 mm and high-grade and estrogen receptor-negative tumors were observed in 39 (36.8%) and 20 (18.9%) patients, respectively. The 7-year ipsilateral breast tumor recurrence (IBTR)-free survival rate was 95.3%. Resection margin (<1 or > or =1 mm) was the significant prognostic factor for IBTR in univariate and multivariate analyses (p < 0.001 and p = 0.016, respectively). CONCLUSION: Postoperative RT for DCIS can achieve favorable treatment outcome. Resection margin was the important prognostic factor for IBTR in the DCIS patients who underwent postoperative RT.

Severe neurologic complication after epidural anesthesia is very rare. We experinced a case of cauda equina syndrome following epidural anesthesia with 2% lidocaine 20 ml, alkalinized with sodium bicarbonate and 1: 200,000 epinephrine added in female patient underwent abdominal hysterectomy. She complained hypoesthesia of buttock, perineum, left leg and weakness of left leg. She also suffered from urinary retension and defecation difficulty and abdominal discomfort 2 days after epidural block. In MRI taken 4 days after block, spinal stenosis (L4-5) and mild disc bulging (L3-4) were noted. She was treated with medication, bladder training and physical therapy and recovered slowly but gradually, finally discharged 2 months after block with mild weakeness of left leg. We suggest the causative factors are the temporary neural compression due to spinal stenosis and the spinal cord ischemia due to vascular spasm because of added epinephrine.
