PURPOSE: To evaluate the usefulness of supine lateral bone mineral density (BMD) measurement using DXA bycomparing AP and lateral spine BMD in patients with degenerative change. MATERIALS AND METHODS: Six hundred andseventy-two women underwent AP and lateral BMD measurement of L-spine, using DXA. Spur changes and end-platesclerosis were considered as degenerative change, and osteoporosis was defined according to WHO criteria. Theratio of mid-lateral BMD to AP BMD was calculated and the differences in ratio were analyzed in the degenerativegroup and controls, according to aging and osteoporosis, using the t test and ANOVA. The correlation coefficiencybetween aging and AP BMD and lateral BMD, respectively, was calculated. RESULT: The mLat/AP ratio in the controland degenerative group was 0.710(0.005 / 0.622(0.028 (p=0.003) in the 40-49-year-old group, 0.663(0.006 /0.612(0.016 (p=0.002) in the 50-59-year-old group, 0.626(0.015 / 0.552(0.023 (p=0.007) in the 60-69 year-oldgroup, and 0.717(0.028 / 0.600(0.045 (p=0.076) in those aged over 70. The ratio was 0.656(0.015 / 0.598(0.038(p=0.099) in osteoporosis, 0.684(0.008 / 0.596(0.016 (p=0.000) in osteopenia, and 0.688(0.005 / 0.583(0.019(p=0.000) in normal subjects, showing that lateral BMD is more sensitive than AP BMD, especially in thedegenerative group. There was negative correlation between aging and AP BMD(r= -0.545), lateral BMD(r= -0.571),and mid-lateral BMD(r=-0.583). CONCLUSION: In a selective group of patients with degenerative change, supinelateral BMD measurement of L-spine is useful.

OBJECTIVE: This study is performed in order to compare T2* weighted magnetic resonance(T2*W MR) image to computerized tomography(CT) and conventional magnetic resonance(MR) image for the detection of minute traumatic intracerebral hemorrhage. METHODS: A series of 40 patients with head trauma underwent CT and MR image including T2*W MR sequnence. The authors compared T2*W MR image to CT and conventional MR image in the diagnosis of traumatic intracerebral hemorrhage. RESULTS: Thirty five of 40 patients(88%) were revealed the hemorrhagic foci in the T2*W MR image, whereas 30 patients(75%) were revealed in the conventional MR image, 18 patients(45%) in the CT. Therefore it is concluded that T2*W MR image is more sensitive than CT or conventional MR image in the diagnosis of minute traumatic intracerebral hemorrhage in patients with head trauma. CONCLUSION: If headache is persisted in the head trauma patients with negative CT and MR image finding, We recommend T2*W MR image.

A novel glucanhydrolase from a mutant of Lipomyces starkeyi KSM 22 has additional amylase activity besides mutanolytic activity and has been suggested as promising anti-plaque agent. It has been shown effective in hydrolysis of mutan, reduction of mutan formation by Streptococcus mutans and removal pre-formed sucrosedependent adherent microbial film and has been strongly bound to hydroxyapatitie. These in vitro properties of Lipomyces starkeyi KSM 22 glucanhydrolase are desirable for its application as a dental plaque control agent. In human experimental gingivitis model and 6 month clinical trial, mouthrinsing with Lipomyces starkeyi KSM 22 dextranase was comparable to 0.12% chlorhexidine mouthwash in inhibition of plaque accumulation and gingival inflammation and local side effect was negligible. This study was aimed to evaluate the cytotoxic effect of Lipomyces starkeyi KSM 22 glucanhydrolase on human gingival fibroblasts. Primary culture of human gingival fibroblasts at the 4th to 6th passages were used. Glucanhydrolase solution was made from lyophilized glucanhydrolase powder from a mutant of Lipomyces starkeyi KSM 22 solved in PBS and added to DMEM medium to the final concentration of 0.5, 1, and 2 unit. Cells were exposed to glucanhydrolase solution or 0.1 % chlorhexidine and the cells cultured in DMEM with 10% FBS and 1% antibiotics as control. After exposure, the morphological change, cell attachment, and cell activity by MTT assay were evaluated in 0.5, 1.5, 3, 6, 24 hours after treatment. The cell proliferation and cell activity was also evaluated at 2 and 7 days after 1 minute exposure, twice a day. The cell morphology was similar between the Lipomyces starkeyi KSM 22 glucanhydrolase groups and control group during the incubation periods, while most fibroblasts remained as round cell regardless of incubation time in the chlorhexidine group. The numbers of the attached cells in the glucanhydrolase groups were comparable to that of control and significantly higher than the chlorhexidine group. The numbers of the proliferated cells in the glucanhydrolase groups at 7 days of incubation were comparable to the control group and higher than the chlorhexidine group. The cell activity in glucanhydrolase groups paralleled with the increased cell number by attachment and proliferation. According to these results, Lipomyces starkeyi KSM 22 glucanhydrolase has little harmful effect on attach-ment and proliferation of human gingival fibroblasts, in contrast to 0.1% chlorhexidine which was cytotoxic to human gingival fibroblasts. Therefore this glucanhydrolase preparation is considered as a safe and promising agent for new mouthwash formula in the near future.

PURPOSE: Laparoscopic left lateral sectionectomy (LLLS) has been widely accepted due to benefits of minimally invasive surgery. Some surgeons prefer to isolate glissonian pedicles to segments II and III and to control individual pedicles with surgical clips, whereas opt like to control glissonian pedicles simultaneously using endoscopic stapling devices. The aim of this study was to find the rationale of LLLS using endoscopic staples. METHODS: We retrospectively analyzed and compared the clinical outcomes (operation time, drainage length, transfusion, hospital stay, and complication rate) of 35 patients that underwent LLLS between April 2004 and February 2012. Patients were dichotomized by surgical technique based on whether glissonian pedicles were isolated and controlled (the individual group, n = 21) or controlled using endoscopic staples at once (the batch group, n = 14). RESULTS: Mean operation time was 265.3 +/- 21.3 minutes (mean +/- standard deviation) in the individual group and 170 +/- 22.9 minutes in the batch group. Operation time in the batch group was significantly shorter than the individual group (P = 0.007). Mean drainage length was 4.8 +/- 1.6 and 2.6 +/- 1.5 days in the individual and the batch group. There was significantly shorter in the batch group, also (P = 0.006). No transfusion was required in the batch group, but 4 patients in the individual group needed transfusion. Mean hospital stay was 10.7 +/- 1.1 and 9.4 +/- 0.8 days in the individual and the batch groups (P = 0.460). There were no significant complications or mortality in both groups. CONCLUSION: LLLS using endoscopic staples (batch group) was found to be an easier and safer technique without morbidity or mortality.

Tilianin was separated and authenticated from the seeds of Dracocephalum moldavia, a Uygur medicine, by chromatographic technique and spectroscopic method. The purity of tilianin is more than 98% determined by HPLC area normalization method. Thin layer chromatography (TLC) method was used to separate tilianin from D. moldavia by mixture of chloroform-methanol (5: 1) as a developing solvent on high performance silicagel precoated plate (SGF254) and using aluminium trichloride as a chromogenic agent for qualitative identification of D. moldavia. To establish a HPLC method for quantitative analysis of D. moldavia, tilianin was used as a Quantitative marker and separated on a C18 (4.6 mm x 250 mm, 5 μm) column with acetonitrile-01% formic acid (25: 75) as the mobile phase and detected at 330 nm. The calibration curve of tilianin displayed ideal linearity over the range of 0.617 2-123.44 μg x mL(-1) with a regression equation of Y = 33.773X - 0.824 8 (r = 1). The average recovery of tilianin was 101.0% with RSD of 3.7%. The RSD values of intra-day and inter-day precision were less than 2%. The content of tilianin in 4 batches of the authenticated semen of D. Moldavia was between 0.016 and 0.187 mg x g(-1). The qualitative and quantitative method established is suitable for the quality evaluation and assessment of semen of D. Moldavia.

BACKGROUND: The aim of this study was to compare the streamlined liner of the pharynx airway (SLIPA), a new supraglottic airway device (SGA), with the laryngeal mask airway ProSeal(TM) (PLMA) during general anesthesia. METHODS: Sixty patients were randomly allocated to two groups; a PLMA group (n = 30) or a SLIPA group (n = 30). Ease of use, first insertion success rate, hemodynamic responses to insertion, ventilatory efficiency and positioning confirmed by fiberoptic bronchoscopy were assessed. Lung mechanics data were collected with side stream spirometry at 10 minutes after insertion. We also compared the incidence of blood stain, incidence and severity of postoperative sore throat and other complications. RESULTS: First attempt success rates were 93.3% and 73.3%, and mean insertion time was 7.3 sec and 10.5 sec in PLMA and SLIPA. There was a significant rise in all of hemodynamic response from the pre-insertion value at one minute following insertion of SLIPA. But, insertion of PLMA was no significant rise in hemodynamic response. There was no statistically significant difference in the mean maximum sealing pressure, gas leakage, lung mechanics data, gastric distension, postoperative sore throat and other complication between the two groups. Blood stain were noted on the surface of the device in 40% (n = 12) in the SLIPA vs. 6.7% (n = 2) in the PLMA. CONCLUSIONS: The SLIPA is a useful alternative to the PLMA and have comparable efficacy and complication rates. If we acquire the skill to use, SLIPA may be considered as primary SGA devices during surgery under general anesthesia.

BACKGROUND: Emergence agitation frequently occurs after desflurane anesthesia in children. We designed this study to find the optimal dose of fentanyl for the prevention of emergence agitation after desflurane anesthesia in children for tonsillectomy. METHODS: Eighty-one patients (3-10 yr) receiving desflurane anesthesia for tonsillectomy was randomly allocated to one of 3 groups. Fentanyl 1 microg/kg (group 1, n = 26), 2 microg/kg (group 2, n = 27), 3 microg/kg (group 3, n = 28) was administered intravenously just before inducing anesthesia. Anesthesia was maintained with desflurane. The recovery characteristics, such as the time to first movement, extubation and discharge from the recovery room were assessed. And patients reported their frequency of emergence agitation and severity of postoperative pain at recovery room. RESULTS: There were no significant differences between the three groups regarding the time to extubation and discharge from the recovery room. The incidence of emergence agitation was 42% in group 1, 25% in group 2, 10% in group 3 and that was significantly lower in group 3 than in group 1 (P < 0.05). The incidence of severe pain was lower in group 3 than in group 1 and group 2 (P < 0.05). CONCLUSIONS: In children undergoing tonsillectomy with desflurane anesthesia, 2 microg/kg and 3 microg/kg of fentanyl given just before induction had a reduced incidence of emergence agitation without a delay in recovery.
