Abstract
PURPOSE We aimed to develop and investigate positional reproducibility using a fixation device (Unity Brain Tumor Immobilization Device, UBID) in brain tumor patients undergoing magnetic resonance (MR)-guided radiotherapy (RT) with a 1.5 Tesla (T) MR-linear accelerator (LINAC) to evaluate its feasibility in clinical practice and report representative cases of central nervous system (CNS) tumor patients. MATERIALS AND METHODS Quantitative analysis was performed by comparing images obtained by placing only the MR phantom on the couch with those obtained by placing UBID next to the MR phantom. Twenty patients who underwent RT for CNS tumors using 1.5T MR-LINAC between June 2022 and October 2022 were retrospectively analyzed. Among them, five did not use UBID, whereas 15 used UBID. The positional reproducibility of UBID was evaluated using the median interfractional and intrafractional errors in the first 10 fractions. RESULTS Each MR quality factor of the MR phantom with UBID satisfied the criteria presented by Elekta. Median values of median shifts in the mediolateral, anteroposterior, and craniocaudal axes for interfractional errors were 2.98-mm, 2.35-mm, and 1.40-mm, respectively. For intrafractional errors, the median values were 0.05-mm, 0.03-mm, and 0.06-mm, respectively. The median values of the median rotations in pitch, roll, and yaw for both interfractional and intrafractional rotations were 0.00°. One patient diagnosed with an optic nerve sheath meningioma received RT with motion monitoring during irradiation. In two patients, changes in the tumor cavity and residual lesions were observed in the MR images obtained using 1.5T MR-LINAC on the day of the first treatment and immediately before the 21st fraction, respectively; therefore, offline/online adaptation was performed. CONCLUSION The reproducible and immobile UBID is clinically feasible in patients with CNS tumors receiving RT with 1.5T MR-LINAC. Based on our initial experience, we developed a workflow for 1.5T MR-LINAC treatment of CNS tumors.

Abstract
BACKGROUND Pancreatic cysts are common. However, most studies are based on data collected from individual centers. The present study aimed to evaluate the changes of management patterns for pancreatic cystic lesions (PCLs) by analyzing large epidemiologic data. METHODS Between January 2007 and December 2018, information regarding pancreatic cystic lesions was acquired from the nationwide Health Insurance Review and Assessment Service database in Korea. RESULTS The final number of patients with pancreatic cysts was 165 277 among the total claims for reimbursement of 855 983 associated with PCLs over 12 years. The total number of claims were increased from 19 453 in 2007 to 155 842 in 2018 and the prevalence increased from 0.04% to 0.23%. For 12 years, 2874 (1.7%) had pancreatic cancer and 8212 (5.0%) underwent surgery, and 36 had surgery for twice (total 8248 pancreatectomy). After ruling out claims from the first 3 years of washout period, the incidence increased from 9891 to 24 651 and the crude incidence rate of PCLs expanded from 19.96 per 100 000 to 47.77 per 100 000. Compared to specific neoplasm codes (D136 or D377), the use of pancreatic cyst code (K862) has been remarkably increased and the most common since 2010. The annual number of pancreatectomies increased from 518 to 861 between 2007 and 2012, and decreased to 596 until 2018. The percentage of pancreatic cancer in patients who received pancreatectomy increased from 5.6% in 2007 to 11.7% in 2018. CONCLUSIONS The incidence of PCLs is rapidly increasing. Among PCLs, indeterminate cyst is increasing outstandingly. A trend of decreasing in the number of resections and increasing cancer rates among resected cysts may be attributed to the updated international guidelines.

Abstract
Introduction FOLFIRINOX (the combination of 5-fluorouracil, leucovorin, irinotecan, and oxaliplatin) is the preferred systemic regimen for locally advanced pancreatic cancer (LAPC). Furthermore, stereotactic body radiation therapy (SBRT) is a promising treatment option for achieving local control in these patients. However, clinical outcomes in patients with LAPC treated using FOLFIRINOX followed by SBRT have not been clarified. Therefore, we aimed to evaluate clinical outcomes of induction FOLFIRINOX treatment followed by SBRT in patients with LAPC. Methods To this end, we retrospectively reviewed the medical records of patients with LAPC treated with induction FOLFIRINOX followed by SBRT in a single tertiary hospital. We evaluated overall survival (OS), progression-free survival (PFS), resection rate, SBRT-related adverse events, and prognostic factors affecting survival. Results Fifty patients were treated with induction FOLFIRINOX for a median of 8 cycles (range: 3-28), which was followed by SBRT. The median OS and PFS were 26.4 (95% confidence interval [CI]: 22.4-30.3) and 16.7 months (95% CI: 13.0-20.3), respectively. Nine patients underwent conversion surgery (eight achieved R0) and showed better OS than those who did not (not reached vs. 24.1 months, p = 0.022). During a follow-up period of 23.6 months, three cases of grade 3 gastrointestinal bleeding at the pseudoaneurysm site were noted, which were managed successfully. Analysis of the factors affecting clinical outcomes revealed that a high radiation dose (≥ 35 Gy) resulted in a higher rate of conversion surgery (25% [8/32] vs. 5.6% [1/18], respectively) and was an independent favorable prognostic factor for OS in the adjusted analysis (hazard ratio: 2.024, 95% CI: 1.042-3.930, p = 0.037). Conclusion Our findings suggest that induction FOLFIRINOX followed by SBRT in patients with LAPC results in better survival with manageable toxicities. A high total SBRT dose was associated with a high rate of conversion surgery and could afford better survival.

Abstract
Abstract
Background/Introduction
The relative importance of the left atrial reservoir strain (LARS) compared to the parameters constituting the HFA-PEFF score developed as a diagnostic tool for patients with heart failure with preserved ejection fraction (HFpEF) is not well known.
Purpose
We aimed to identify the relative importance of LARS compared with variables associated with HFpEF and HFA-PEFF score including echocardiographic parameters, demographic data, and NT-proBNP.
Methods
From August 2021 to March 2022, we obtained data retrospectively from the participants visiting our clinic in a single cardiovascular center. The 1,252 participants with sinus rhythm and ejection fraction more than 50% were enrolled in the present study (61.8±16.6 years and 55% female). Multivariable regression analysis using backward elimination and random forest analysis, supervised learning algorithm, were performed to identify the relative importance of LARS on the HFA-PEFF score.
Results
The median HFA-PEFF score was 3 points (interquartile range 2 to 4 points). Two hundred forty-one subjects (19.2%) had more than 5 points. LARS showed a moderate correlation with the HFA-PEFF score (r=−0.632, p<0.001). In multivariable regression analysis, LARS was independent variable affecting HFA-PEFF score with female sex, left atrial volume index (LAVI), septal e', E over e' (septal), the maximal tricuspid regurgitation velocity (TR-Vmax), left ventricular global longitudinal strain (LV-GLS), NT-proBNP, interventricular septal wall thickness (standardized β=−0.106; P<0.001). In random forest analysis, LARS was a more relatively important variable than TR-Vmax, NT-proBNP, septal E/e', septal e', the major echocardiographic components of HFA-PEFF score estimating more than 5 points of HFA-PEFF score.
Conclusions
LA reservoir strain is one of the important factors with components of the HFA-PEFF score which is a useful tool to assess the patients with HFpEF.

Abstract
Cavernous hemangiomas occur very rarely in the cavernous sinus. This study aimed to evaluate the efficacy of Gamma Knife surgery (GKS) on cavernous sinus cavernous hemangioma (CSCH) and to analyze the temporal volume change. We retrospectively reviewed the clinical data of 26 CSCH patients who were treated with GKS between 2001 and 2017. Before GKS, 11 patients (42.3%) had cranial neuropathies and 5 patients (19.2%) complained of headache, whereas 10 patients (38.5%) were initially asymptomatic. The mean pre-GKS mass volume was 9.3 mL (range, 0.5-31.6 mL), and the margin dose ranged from 13 to 15 Gy according to the mass volume and the proximity to the optic pathway. All cranial neuropathy patients and half of headache patients showed clinical improvement. All 26 patients achieved mass control; remarkable responses (less than 1/3 of the initial mass volume) were shown in 19 patients (73.1%) and moderate responses (more than 1/3 and less than 2/3) in 7 patients (26.9%). The mean final mass volume after GKS was 1.8 mL (range, 0-12.6 mL). The mean mass volume at 6 months after GKS was 45% (range, 5-80%) compared to the mass volume before GKS and 21% (range, 0-70%) at 12 months. The higher radiation dose tended to induce more rapid and greater volume reduction. No treatment-related complication was observed during the follow-up period. GKS could be an effective and safe therapeutic strategy for CSCH. GKS induced very rapid volume reduction compared to other benign brain tumors.

Background
Left ventricular global longitudinal strain (LV GLS) offers sensitive and reproducible measurement of myocardial dysfunction. The authors sought to evaluate whether LV GLS at the time of diagnosis may predict LV reverse remodeling (LVRR) in DCM patients with sinus rhythm and also investigate the relationship between baseline LV GLS and follow-up LVEF.
Methods
We enrolled patients with DCM who had been initially diagnosed, evaluated, and followed at our institute.
Results
During the mean follow-up duration of 37.3 ± 21.7 months, LVRR occurred in 28% of patients (n = 45) within 14.7 ± 10.0 months of medical therapy. The initial LV ejection fraction (LVEF) of patients who recovered LV function was 26.1 ± 7.9% and was not different from the value of 27.1 ± 7.4% (p = 0.49) of those who did not recover. There was a moderate and highly significant correlation between baseline LV GLS and follow-up LVEF (r = 0.717; p <0.001).
Conclusion
There was a significant correlation between baseline LV GLS and follow-up LVEF in this population.

Abstract
Abstract
Objectives
A botanical drug derived from the ethanolic extract composed of Clematis chinensis Osbeck (Ranunculaceae), Trichosanthes kirilowii Maximowicz (Cucurbitaceae) and Prunella vulgaris Linné (Lamiaceae) has been used to ameliorate rheumatoid arthritis as an ethical drug in Korea. In our study, we investigated the effect of this herbal complex extract (HCE) on schizophrenia-like behaviours induced by MK-801.
Methods
HCE (30, 100 or 300 mg/kg, p.o) was orally administered to male ICR mice to a schizophrenia-like animal model induced by MK-801. We conducted an acoustic startle response task, an open-field task, a novel object recognition task and a social novelty preference task.
Key findings
We found that a single administration of HCE (100 or 300 mg/kg) ameliorated MK-801-induced abnormal behaviours including sensorimotor gating deficits and social or object recognition memory deficits. In addition, MK-801-induced increases in phosphorylated Akt and GSK-3β expression levels in the prefrontal cortex were reversed by HCE (30, 100 or 300 mg/kg).
Conclusions
These results imply that HCE ameliorates MK-801-induced dysfunctions in prepulse inhibition, social interactions and cognitive function, partly by regulating the Akt and GSK-3β signalling pathways.

Abstract
Spinosin, which is traditionally used for sedation and sleep disorders, has recently shown potential effects in alleviating memory loss. As spinosin is the main bioactive component in a standardized dried 50% ethanol extract of the seeds of Zizyphus jujuba var. spinosa, a Phase IIb clinical trial is ongoing, in Korea for the combination of the above extract formulated in a tablet (DHP1401 tablet) with donepezil hydrochloride (Aricept® tablet) in patients with mild to moderate Alzheimer's disease. Therefore, to promote safety and efficacy evaluations, a reliable method for the simultaneous detection and analysis of the two drugs is needed. Toward this end, in this study, we established and validated a rapid and sensitive LC-MS/MS method for the simultaneous determination of donepezil, its pharmacologically active metabolite 6-O-desmethyl donepezil, and spinosin in beagle dog plasma (50 μL). After optimization of the system, we used methanol for simple protein precipitation. Chromatographic separation was performed using a Phenomenex Luna C18 column (100 × 2.0 mm, 3 μm) with a mobile phase consisting of 0.1% formic acid in acetonitrile-0.1% formic acid in distilled water (2:8, v/v) at a flow rate of 0.65 mL/min. All analytes were detected and quantified in selected reaction monitoring mode. All calibration curves showed good linearity (r ≥ 0.9965) over the concentration range of 0.02-20, 0.02-10, and 0.5-250 ng/mL for donepezil, for 6-O-desmethyl donepezil, and spinosin, respectively. This validated method was then successfully applied to a pharmacokinetic study in beagle dogs with no evidence for potential drug-drug interactions between DHP1401 and donepezil hydrochloride. This information and optimized assay can be useful for the anticipated co-administration of these two drugs in clinical settings.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The seeds of Zizyphus jujuba var. spinosa (Bunge) Hu ex H.F. Chow (Rhamnaceae) have long been treated as hypnotic agent for sleep disturbances in traditional Chinese and Korean medicine and many previous studies have focused on its effect in central nervous system. AIMS OF STUDY The present study aimed to provide evidence showing that the ethanol extract of Zizyphus jujuba var. spinosa seeds (EEZS), which may regulate plasmin activity, has the potential to serve as a therapeutic agent for AD. MATERIALS AND METHODS Synaptic function was determined by measuring long-term potentiation (LTP) in Shaffer-collateral pathway of the hippocampus. Protein levels of plasmin or plasminogen were examined using western blotting. Plasmin activity was measured using ELISA. Cognitive functions were measured using passive avoidance and object recognition tests in the 5XFAD mice. RESULTS Our in vitro analysis revealed that EEZS-treated hippocampal slices from 5XFAD mice, a mouse model of AD, showed significantly higher long-term potentiation levels than did vehicle-treated hippocampal slices from 5XFAD mice (P < 0.05). Additionally, EEZS significantly elevated the plasmin level and activity in the hippocampal slices from 5XFAD mice (P < 0.05). Co-treating the slices with EEZS and 6-aminocaproic acid, a plasmin inhibitor, blocked the ameliorating effects of EEZS on the synaptic deficits that were present in 5XFAD mice. Compatible with the in vitro study, the results of our in vivo investigation showed that administering EEZS orally to 5XFAD mice ameliorated their memory impairments. Orally administered EEZS also elevated the plasmin level and activity in the hippocampus of 5XFAD mice. CONCLUSIONS Collectively, our findings suggest that EEZS alleviates the AD-like symptoms in 5XFAD mice by regulating of plasmin activity and EEZS may be a suitable treatment for AD.

Abstract
A new phenylpropanoid (1), a new alkaloid (11), and a new natural polyacetylene (17), together with nine phenolic compounds (2-10), five alkaloids (12-16), three polyacetylenes (18-20), three triterpenoidal saponins (21-23), one phenylethanoid glycoside (24), and three hexyl glycosides (25-27) with previous known structures, were isolated from the roots of Codonopsis lanceolata. All of the isolates 1-27 were evaluated for their inhibitory effects on LPS-induced nitric oxide (NO) production in RAW 264.7 macrophages and cell viability in A2780 human ovarian cancer cells. Among the isolates, lancemasides A and B have a significant inhibitory effect on the production of NO in RAW264.7 cells (IC50 values < 50 μM). In A2780 cells, lancemaside A exhibited the most potent inhibitory effect on cell viability. This is the first report on the pharmacological activities of lancemaside B (22).

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The seeds of Ziziphus jujuba var. spinosa (Bunge) Hu ex H.F Chow (Rhamnaceae) and the roots of Codonopsis lanceolata (Siedbold & Zucc.) Benth. & Hook. f ex Trautv. (Campanulaceae), contained in the DHP1402, have long been used for treating dementia or hypomnesia as folk medicine. AIM OF THE STUDY It has been reported that Z. jujuba var. spinosa and C. lanceolata are effective in improving cognitive function, but via different mechanisms. Therefore, in the present study, we evaluated the synergistic effects of Z. jujuba var. spinosa and C. lanceolata on scopolamine-induced memory impairment. MATERIALS AND METHODS Scopolamine, a cholinergic muscarinic receptor antagonist, was used to induce cognitive dysfunction. We employed several behavioral tasks to estimate the synergistic effect of the seeds of Z. jujuba var. spinosa and the roots of C. lanceolata. In addition, we introduced the Western blotting, the antagonism passive avoidance task to investigate a synergistic effect of an herbal formulation. RESULTS Synergistic effects of a combination of Z. jujuba var. spinosa and C. lanceolata at a 5:1 ratio [(w/w), DHP1402] were observed against cognitive dysfunction in the passive avoidance and Y-maze tasks. DHP1402 also ameliorated memory deficits in a dose-dependent manner in these behavioral tasks, as well as in the Morris water maze task. According to the Western blot results, the phosphorylation levels of protein kinase A (PKA), extracellular signal-regulated kinase (ERK) and cAMP response element-binding protein (CREB) in the hippocampus were also increased in a synergistic manner after the administration of DHP1402. In addition, we found that the effects of DHP1402 on cognitive function were mediated by N-methyl-D-aspartate (NMDA) receptor signalling, based on the antagonism studies. Furthermore, we found that DHP1402 has inhibitory activity against acetylcholinesterase (AChE). CONCLUSION DHP1402 attenuates cholinergic blockade-induced cognitive dysfunction through NMDA receptor modulation, PKA-ERK-CREB pathway activation, and AChE inhibition. Therefore, DHP1402 could be a candidate for alleviating cognitive dysfunction.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE As the seed of Zizyphus jujuba var. spinosa (Bunge) Hu ex H.F. Chow (Rhamnaceae) has been used to sleep disturbances in traditional Chinese and Korean medicine, many previous studies have focused on its sedative effect. AIM OF THE STUDY Recently, we reported the neuroprotective effect of the effect of Z. jujuba var. spinosa. However, its effects on synaptic function have not yet been studied. In this project, we examined the action of ethanol extract of the seed of Z. jujuba var. spinosa (DHP1401) on synaptic transmission in the hippocampus. MATERIALS AND METHODS To investigate the effects of DHP1401, field recordings were conducted using hippocampal slices (400µm). Object recognition test was introduced to examine whether DHP1401 affect normal recognition memory. RESULTS DHP1401 (50μg/ml) induced a significant increase in synaptic activity in Shaffer collateral pathway in a concentration-dependent manner. This increase of synaptic responses was blocked by NBQX, a broad spectrum α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor antagonist, but not IEM-1460, a Ca2+-permeable AMPAR blocker. Moreover, U0126, a mitogen-activated protein kinase inhibitor, SQ22536, an adenylyl cyclase inhibitor, and PKI, a protein kinase A inhibitor, blocked DHP1401-induced increase in synaptic transmission. Finally, DHP1401 facilitated object recognition memory. CONCLUSIONS These results suggest that DHP1401 increase synaptic transmission through increase of synaptic AMPAR transmission via MAPK, AC and PAK.

Abstract
BACKGROUND/AIM CD133 is an important, but not exclusive, biomarker of colorectal cancer (CRC) stem cells. MATERIALS AND METHODS In order to identify other CRC stem cell-specific genes, we performed a comparative expression profiling of CD133(+) and CD133(-) cell populations in primary and metastatic tumors from four patients with CRC. CD133(+) and CD133(-) CRC cells were isolated using MagSweeper and used for whole-transcriptome analysis with RNA-Seq. RESULTS We found that in CD133(+) cells, 17 genes (RNASE2, PRB2, IL4, MGC27382, CLEC4C, SALL3, GIMAP1, ISG15, LOC728875, ZIK1, ICAM2, CCDC7, CDYL2, LRRC2, ZEB1, OSTF1 and CCDC144B) were significantly up-regulated compared to CD133(-) CRC cells. Among them, IL4 has been known as an inducer of survivin implicated in the survival and proliferation of cancer cells. However, the prognostic value of survivin in CRC is controversial. We evaluated survivin expression in formalin-fixed paraffin-embedded tumor samples of 188 patients with CRC by immunohistochemistry. Survivin over-expression was detected in 85 patients (45.2%) and was significantly associated with primary tumor sites (p=0.028), lymph node metastasis (p=0.029) and advanced III/IV CRC stages (AJCC 7; p=0.001). Furthermore, survivin up-regulation correlated with reduced disease-free survival (DFS; p=0.021) and overall survival (OS; p<0.000) and was proved to be an independent prognostic factor for both DFS and OS in multivariate analysis. CONCLUSION Our data suggest that CD133(+) CRC stem cells have a distinct expression pattern and that survivin, up-regulated by differentially expressed IL-4, is a candidate biomarker for the prediction of recurrence and survival in CRC.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Alzheimer's disease is a neurodegenerative disorder associated with cognitive impairment and cholinergic neuronal death. INM-176 is a standardized ethanolic extract of Angelica gigas Nakai that has been traditionally used in herbal medicine in China, Japan, and Korea to treat anemia or as a sedative. We investigated whether INM-176 exhibits anti-amnesic effects. MATERIALS AND METHODS Memory impairment was induced by scopolamine, a cholinergic muscarinic receptor antagonist, or amyloid β(1-42) (Aβ(1-42)) protein. Anti-amnesic effects of INM-176 were measured by the passive avoidance and the Morris water maze tasks in mice. We also examined the effect of INM-176 on the acetylcholinesterase activity, as well as Aβ(1-42) protein-induced astrogliosis or cholinergic neuronal loss in the brain. RESULTS Scopolamine-induced cognitive dysfunction was significantly attenuated by a single or sub-chronic administration of INM-176 in the passive avoidance and the Morris water maze tasks. A single or sub-chronic administration of INM-176 also ameliorated memory impairments induced by Aβ(1-42) protein. INM-176 inhibited acetylcholinesterase activity in the hippocampal tissue in vitro and ex vivo. In addition, INM-176 attenuated the Aβ(1-42) protein-induced astrocyte activation in the hippocampus as well as cholinergic neuronal damage in the CA3 region of the hippocampus and the nucleus basalis of Meynert. CONCLUSION These results suggest that the memory ameliorating effects of INM-176 on scopolamine- or Aβ(1-42) protein-induced memory impairment are mediated, in part, via acetylcholinesterase inhibition and neuroprotective activities.

Abstract
Hereditary non-polyposis colorectal cancer (HNPCC) is an autosomal dominant syndrome characterized by predisposition to early-onset cancers. HNPCC is caused by heterozygous loss-of-function mutations within the mismatch repair genes MLH1, MSH2, MSH6, PMS1, and PMS2. We genotyped the MLH1 and MSH2 genes in patients suffering from Lynch syndrome and in 11 unrelated patients who were diagnosed with colorectal cancer and had subsequently undergone surgery. Five Lynch syndrome patients carried germline mutations in MLH1 or MSH2. Two of these were identified as known mutations in MLH1: deletion of exon 10 and a point mutation (V384D). The remaining three patients exhibited novel mutations: a duplication (937_942dupGAAGTT) in MLH1; deletion of exons 8, 9, and 10; and a point mutation in MLH1 (F396I) combined with multiple missense mutations in MSH2 (D295G, K808E, Q855P, and I884T). The findings underline the importance of efficient pre-screening of conspicuous cases.

Abstract
BACKGROUND Complications associated with laparoscopically assisted gastrectomy (LAG) are not significantly different from those associated with open gastrectomy. However, additional risks related to abdominal access, pneumoperitoneum, and special electrosurgical instruments result in an increased incidence of complications with LAG. This study analyzed the causes and risk factors linked to postoperative morbidity. METHODS A retrospective review analyzed the data of 300 patients who underwent consecutive LAG for gastric cancer in our department from May 2003 to October 2006. Among the 300 patients, total gastrectomy was performed for 42 patients, distal gastrectomy for 258 patients, and proximal gastrectomy for 3 patients. The clinical and operative data obtained included body mass index, medical comorbidities, history of previous abdominal surgery, operative time, type of surgery, extent of lymph node dissection according to the Japanese Guideline, number of retrieved lymph nodes and lymph node metastases, additional operative procedure, depth of tumor invasion, and disease stage. The outcome data consisted of mortality, major morbidities, and postoperative hospital stay. The 300 cases were divided into two periods: 50 cases in the first period and 250 cases in the second period. RESULTS Postoperative complications developed in 61 cases (20.3%), wound infection in 21 cases (7%), intraabdominal abscess in 3 cases (1%), bleeding in 12 cases (4%), stenosis in 13 cases (4.3%), leakage in 3 cases (1%), acute pancreatitis in 2 cases (0.7%), pulmonary complication in 4 cases (1.3%), renal complication in 4 cases (1.3%), and cardiac complication in 2 cases (0.7%). The 30-day mortality rate was 0.7% (n=2). Univariate analysis proved that gender, operative period, comorbidity, and operative times were important risk factors. Multivariate analysis proved that cormobidity and operative period were important risk factors. CONCLUSION The data suggest that LAG can be performed with acceptable perioperative complication rates. The surgeon's experience and careful patient selection determined optimal patient outcomes.

Abstract
OBJECTIVE The in vitro effects of staphylococcal alpha-toxin on ciliary activity were investigated at different concentrations and exposure times. STUDY DESIGN Ciliated epithelial cells of the sphenoid sinus were taken from patients operated on for pituitary tumors. Video-computerized analysis technique and transmission electron microscopy were used to analyze the effects of the toxin on ciliary activity. METHODS Ciliary beat frequency (CBF) was measured in four different concentrations of alpha-toxin including 0.1, 1, 10, and 50 microg/mL. CBF was measured at 2, 4, 6, 12, 24, and 48 hours after administration of the toxin. To observe reversibility of the reduced ciliary activity, after 24-hour incubation in the media containing 10 microg/mL of alpha-toxin, the media were replaced with alpha-toxin-free media. The tissues were also processed for transmission electron microscopy to observe ultrastructural changes of the epithelial cells. RESULTS CBF increased significantly at 2-hour incubation and then decreased significantly after 12-hour incubation in 10 microg/mL of alpha-toxin (P< .05, repeated-measures ANOVA). The transmission electron microscopic findings showed mitochondrial swelling and a slight protrusion of the plasma membrane of the cilia. In toxin-free media, loss of ciliary activity was not recovered. CONCLUSIONS CBF increased at first, but with increasing incubation time ciliary movements decreased gradually and stopped eventually. This loss of CBF may be an irreversible change associated with ultrastructural changes in the mitochondria and the plasma membrane of the cilia.

Abstract
OBJECTIVE There have been few reports on the effects of free oxygen radicals on ciliary mobility of nasal respiratory epithelial cells. The aim of this study was to determine the effects of free radicals and antioxidants on human nasal epithelial cells (HNECs) using video-computerized analysis. METHODS Human nasal epithelial cells were obtained from the nasal cavity of normal volunteers. Ciliary beat frequency (CBF) was calculated as the mean value of ten randomly selected cells. The proportion of the area with normal CBF (above 8 Hz) was calculated from 10 randomly selected sites per specimen. Free radicals were produced by xanthine-xanthine oxidase enzymatic system. The generation of free radicals was confirmed by chemoilluminometer. CBF and the proportion of the area with normal CBF were measured at every 5 min for 30 min after the addition of enzyme. For the evaluation of the antioxidant effects on free radical-mediated ciliary slowing in HNECs, cells were incubated in superoxide dismutase solution (300 unit/ml) for 30 min and 3-aminobenzamide (5 mM). RESULTS Superoxide produced by 0.4 mM xanthine and 400 miliunit/ml xanthine oxidase decreased CBF (7.71 +/- 1.91 Hz). A total of 2 min later, ciliary slowing was evident (3.87 +/- 1.10 Hz). Regarding the changes in proportion of epithelial area that showed normal CBF experimental group showed a significant decrease in percentage of epithelial area with normal CBF over time. Superoxide dismutase prevented ciliary slowing (8.76 +/- 0.99 Hz). Moreover, 3-aminobenzamide, an inhibitor of the DNA repair enzyme poly-ADP ribose polymerase, prevented inhibition of CBF (8.32 +/- 0.61 Hz). CONCLUSIONS These results suggest that oxygen-mediated damage to DNA may be the mechanism of the deterioration effects of oxygen radicals on the ciliated respiratory nasal epithelium.
