In order to find the most suitable conditions of freeze-drying for the long term preservation of lacto-bacillus casei AHU 1055 and Lactobacillus acidophilus JAM 1043, the growth phase, the cryoprotection medium and inoculum size have been studied. The results obtained in this study are summerized as follows : 1. L. casei AHU 1055 and L.acidophilus JAM 1043 reached to stationary phase after incubating at 37˚C for 16hrs and 12hrs in MRS broth, respectively. 2. The highest viability of each strains was obtained in 11% skim-milk for L. casei AHU 1055 and 9% skim-milk for L. acidophilus JAM 1043 as basic cryoprotection medium. 3. The complex medium contained 11% skim milk powder, 2.5% arginine and 3% glucose was the best suspending midium for freeze-drying of L. casei AHU 1055, and the medium contained 9% skim milk powder, 7% glycerol, 9% lactose, 0.5% arginine was the best suspending medium for freeze-drying of L. acidophilus JAM 1043. 4. The strong positive correlation was found between inoculum size and the survival rate in both strains. 5. When the tested strains were cultured and freeze-dried under the best optimal conditions, the survival rates of freeze- dried L. casei AHU 1055 and L. acidophilus JAM 1043 were 85.8% and 84.0%, respectively.

Although it is known that hypothyroidism can cause cardiac dysfunction, it is very hard to find a case report on sudden death due to hypothyroidism. There are only two reported cases on mediline; one is about a 15-year-old girl who died suddenly of Hashimoto's thyroiditis and the other is about a 31-year-old man who also died suddenly of hypothyroidism associated with chronic lymphocytic thyroiditis. Recently we found a young woman who unexpectedly died while she was sleeping. She was diagnosed as hypothyroidism when she went to hospital about a month before she died. At autopsy there were roughly four abnormal findings; Hashimoto's thyroiditis, mild chronic active hepatitis, diverticulosis and accessory spleen. Trace of chlorpheniramine was detected in gastric remains and blood alcohol level was 0.37 percent. To our knowledge, this is the first case reporting sudden and unexpected natural death associated with hypothyroidism in Korea.

<P>Effects of sodium ethanesulfonate (SES) adsorbed on photoelectrode surface on the performance of dye-sensitized solar cells (DSSCs) was investigated. SES-modified photoelectrode was prepared by soaking the TiO2 film to an aqueous SES solution for 20 min. The DSSC with SES-modified TiO2 layer showed an increase in open circuit voltage (V-oc), short circuit current (J(sc)) and fill factor (FF), resulting in a power conversion efficiency of 11.20%, compared to that of reference device with bare TiO2 (10.21%). Electrochemical impedance spectroscopy and open circuit voltage decay measurements revealed that the SES modification of TiO2 surface led to a longer electron lifetime by the suppression of the interfacial charge recombination between photo-injected electrons and I-3(-) ions, resulting in an increase in J(sc) and V-oc, compared with those of a reference device without surface modification.</P>

<P><B>AIM</B></P><P>To evaluate toxicity and treatment outcome of high-dose radiotherapy (RT) for cervical esophageal cancer (CEC).</P><P><B>METHODS</B></P><P>We reviewed a total of 62 consecutive patients who received definitive RT for stage I to III cervical esophageal cancer between 2001 and 2015. Patients who received < 45 Gy, treated for lesions below sternal notch, treated with palliative aim, treated with subsequent surgical resection, or diagnosed with synchronous hypopharyngeal cancer were excluded. Treatment failures were divided into local (occurring within the RT field), outfield-esophageal, and regional [occurring in regional lymph node(s)] failures. Factors predictive of esophageal stenosis requiring endoscopic dilation were analyzed.</P><P><B>RESULTS</B></P><P>Grade 1, 2, and 3 esophagitis occurred in 19 (30.6%), 39 (62.9%), and 4 patients (6.5%), respectively, without grade ≥ 4 toxicities. Sixteen patients (25.8%) developed post-RT stenosis, of which 7 cases (43.8%) were malignant. Four patients (6.5%) developed tracheoesophageal fistula (TEF), of which 3 (75%) cases were malignant. Factors significantly correlated with post-RT stenosis were stage T3/4 (<I>P</I> = 0.001), complete circumference involvement (<I>P</I> < 0.0001), stenosis at diagnosis (<I>P</I> = 0.024), and endoscopic complete response (<I>P</I> = 0.017) in univariate analysis, while complete circumference involvement was significant in multivariate analysis (<I>P</I> = 0.003). A higher dose (≥ 60 Gy) was not associated with occurrence of post-RT stenosis or TEF. With a median follow-up of 24.3 (range, 3.4-152) mo, the 2 y local control, outfield esophageal control, progression-free survival, and overall survival (OS) rates were 78.9%, 90.2%, 49.6%, and 57.3%, respectively. Factors significantly correlated with OS were complete circumference involvement (<I>P</I> = 0.023), stenosis at diagnosis (<I>P</I> < 0.0001), and occurrence of post-RT stenosis or TEF (<I>P</I> < 0.001) in univariate analysis, while stenosis at diagnosis (<I>P</I> = 0.004) and occurrence of post-RT stenosis or TEF (<I>P</I> = 0.023) were significant in multivariate analysis.</P><P><B>CONCLUSION</B></P><P>Chemoradiation for CEC was well tolerated, and a higher dose was not associated with stenosis. Patients with complete circumferential involvement require close follow-up.</P>

Background/Aims: Bicarbonate-containing alginate formulations are reported to be effective for controlling reflux symptoms. However, the efficacy of Lamina G alginate without gas production has not been reported. The aim is to evaluate the efficacy of a non-bicarbonate alginate in individuals with reflux symptoms without reflux esophagitis. Methods: Participants who had experienced heartburn or regurgitation for 7 consecutive days were randomized to one of the following treatment groups: proton pump inhibitors (PPI) plus alginate (combination) or PPI plus placebo (PPI only). In addition, as a reference group, patients received placebo plus alginate (alginate only). The primary endpoint compared the percentage of patients with complete resolution of symptoms for the final 7 days of the treatment. Secondary endpoints compared changes in symptom score, symptom-free days during the treatment period, the Reflux Disease Questionnaire, Patient Assessment of Upper Gastrointestinal Disorders (PAGI)-Quality of Life and PAGI-Symptoms Severity Index scores, the investigator’s assessment of symptoms, and incidence of adverse events. Results: Complete resolution of heartburn or regurgitation was not significantly different between the combination and PPI only groups (58.7% vs 57.5%, p=0.903). The secondary endpoints were not significantly different between the two groups. Complete resolution of heartburn or regurgitation, did not differ between the alginate only reference group and the PPI only group (75.0% vs 57.5%, p=0.146). Conclusions: The addition of non-bicarbonate alginate to PPI was no more effective than PPI alone in controlling reflux symptoms.

<P>AbstractPurpose</P><P>Rapid and accurate diagnosis of spontaneous bacterial peritonitis (SBP) is mandatory for timely treatment in cirrhotic patients. The purpose of this study was to assess the usefulness of two different reagent strips, the UriSCAN and the Multistix10SG, for the rapid bedside diagnosis of SBP.</P><P>Methods</P><P>A total of 75 paracenteses in 53 cirrhotic patients with ascites were performed. All ascitic fluid was analyzed with the two reagent strips, and compared with the manual cell count with differential and ascitic fluid culture. SBP was defined as an ascitic polymorphonuclear cell count ≥250/mm<SUP>3</SUP>.</P><P>Results</P><P>SBP was diagnosed in 18 of the 75 samples. If we considered the positive UriSCAN result of 2 or more, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were all 100%. When we considered the positive UriSCAN result of 3, the sensitivity, specificity, PPV, and NPV were 67%, 100%, 100%, and 89%, respectively. When we considered the positive Multistix10SG result of 3, the sensitivity, specificity, PPV, and NPV were 50%, 100%, 100%, and 87%, respectively.</P><P>Conclusion</P><P>Urine reagent strip might be useful for rapid and accurate diagnosis of SBP in cirrhotic patients with ascites.</P>
