In order to determine the enzyme activity, as expressed in Reitman-Frankel unit, of GOT isozyme present in whole homogenate, mitochondrial fraction and supernatant fraction were prepared from brain tissues of normal adult rabbit, by a differential centrifugal method. The effect of thiopental on the GOT isozyme activity in each fraction was determined and the following results were obtained. 1) The activity of GOT isozyme in whole homogenate of normal rabbit brain tissues was found to be 545+/-2.608 units/mg of wet weight whereas the corresponding figure for the supernatant GOT isozyme was 512+/-3.081 and the value for the mitochondrial GOT isozyme was found to be 34.9+/-1.224. 2) The supernatant GOT isozyme existing in a floating status within the cytoplasm accounted for 94 percent followed by 6.35 percent of mitochondrial GOT isozyme. 3) The activated-peak of mitochondrial GOT isozyme contained in the whole homogenate of adult rabbit brain tissues was found to be at #15 on the tube of elution in comparison to that of #73 for supernatant GOT isozyme, as analyzed by the DEAE-Cellulose column chromasography. 4) The supernant GOT isozyme from the thiopentaltreated brain was proportionaly distorted while mitochondrial GOT isozyme was not influenced. Fro example, treated with thiopental, the supernatant GOT isozyme was divided to be #63 & #73 on the tube in comparison to #15 for the mitochondrial GOT isozyme. 5) The activity of supernatant isozyme was proportionaly reduced as the concentration of thiopental. 6) Fifty percent inhibition dose(1se) of thiopental on the supernatant GOT isozyme was found to be 0.63mM. 7) The inhibitory effect of thiopental on the supernatant GOT isozyme was very high significantly by the statistics. 8) The mchanism by which thiopental inhibits the supernatant GOT isozyme in the adult rabbit brain was found to bh uncompetitive inhibition as its Michaelis-Menten constant Km=58.07mM demonstrated. In view of the above finding it is suggested that the thiopental inhibited selectively the activity of supernatant GOT isozyme of the adult rabbit brain tissues while it did not inhibitnificantly by the statistics. 8) The mechanism by which thiopental inhibits the supernatant GOT isozyme in the adult rabbit brain was found to bh uncompetitive inhibition as it Michaelis-Menten constant of Km=58.07 mM demonstrated. In view of the above findings it is suggested that the thiopental inhibited selectively the activity of supernatant GOT isozyme of the adult rabbit brain tissues while it did not inhibit that of mitochondrial GOT isozyme. The GOT isozyme of adult rabbit brain tissues was divided into thiopental-sensitive GOT isozyme(supernatant GOT isozyme) and thiopental insensitive GOT isozyme(mitochondrial GOT isozyme) Furthermore, it is suggested that the cellular function of the brain can be somewhat hindered, when thiopental is injected into the brain cell, while mitosis of the brain cell is not influenced.

All-in-one adhesives were recently developed for reducing the techique sensitivity and chair time, but lots of concerns were made on bondability, longevity, and microleakage. The object of this study was to evaluate microleakage and marginal quality of all-in-one adhesives using electrochemical method and SEM analysis quantitatively. After making Class V cavities, they were bulk filled with Heliomolar(#A1) after surface treatment with three adhesives: Adper Prompt (Group A), One up bond F (Group O), Xeno III (Group X). Electrical conductivity (microamphere, microA) was checked two times: before and after cavity filling. Percentage of leaky margin was estimated from SEM image (x1,000). The data were statistically analysed: ANOVA and Paired T test for electrical conductivity, Kruskal-Wallis and Mann-Whitney test for marginal quality, Spearman's rho test for checking of relationships between 2 methods. The result were as follows: 1. There was no difference in microleakage between adhesive systems and every specimen showed some of microleakage after filling. 2. Microleakage was reduced about 70% with composite resin filling. 3. Marginal quality was the best in group A, decreasing among groups in the following order: group O, followed by group X. There were significant differences between group A and group X (p=0.015), and between group O and group X (p=0.019). 4. There was no relationship between the microleakage measured by electrochemical method and marginal quality measured by SEM analysis. Within the results of this study, there was no difference in microleakage among groups by electrical conductivity. However, significant difference in marginal quality was seen among groups. It was believed that these dissimilar results might be induced because of their own characteristics. Analysis of microleakage needs various methods for accuracy.

Eighty-nine isolates of Enterobacter spp. from two university hospitals were analyzed by phenotypic and genotypic characteristics for epidemiologic investigation. Most strains were isolated from sputum, urine, wound, pus and catheter tip. Most isolates of Enterobacter spp. were resistant to ampicillin, cefazolin and cefoxitin and 39% of E. cloacae isolates were also resistant to other cephalosporins and aminoglycoside antibiotics except amikacin but all strains were highly susceptible to imipenem and ciprofloxacin. Twenty-six antimicrobial resistance patterns were obtained from E. clacae, but E. aerogenes showed only 4 patterns. Fourty-two plasmid profiles were identified, but plasmid was not detected from 28.4% of E. cloacae and 58% of E. aerogenes. Six biotypes from E. cloacae and three biotypes from E. aerogenes were obtained by carbohydrate metabolism. Fourteen strains of E. cloacae carried conjugative R plasmids and these plasmids were further analyzed. Among them, ten plasmids showed identical antibiogram, molecular weight, and pI value by isoelectric focusing and nearly identical restriction endonuclease fragment pattern. Their parental strains had identical antibiogram, biotype, plasmid profile, and were isolated from 4 different specimens including 6 catheter tips of different patients. But most clinical isolates showed various types of combination and seemed to be different strains. These results indicate that the epidemic strain were present in this hospital and the combination of antibiogram and plasmid analysis can be used to discriminate the epidemic strains of multi-resistant E. cloacae.

The aim of the present study was to investigate the mRNA expression of several cytokines which were not reported previously from interface tissues around loose cemented acetabulum to obtain better understanding of the biological mechanisms connected with aseptic loosening and osteolysis of THA. We investigated mRNA expression for several cytokines (interleukin-1 alpha [IL-l~a], IL-lp, IL-2, IL-2 receptor[2R], IL-4, IL-5, IL-8, IL-10, transforming growth factor-beta [TGF-p], and interferon- gamma [IFN-y]) by reverse transcription-polymerase chain reaction (RT-PCR) and release of metalloproteinase (MMP)-2 and MMP-9 from the cement-bone interface tissues around five loose polyethylene acetabular components. We did not include TNF-a and IL-6 because the biologic effect of the former is so similar to that of IL-1, and the latter fails to stimulate prostaglandin E, or collagenase production by fibroblsts or synovial cells. Expression of mRNA for IL-1p was detected in four, IL-2R and IL-8 in three, IL-10 and TGF-p in two of five interface tissues .No expression of mRNA for IL-la, IL-2, IL-4, IL-5, and IFN-p was detected. Zymographic analysis for gelatinase/type IV collagenase revealed gelatinolytic bands corresponding to metalloproteinase(MMP)-2 and MMP-9 in cemenl-bone interface tissues. Activated cells phagocytose particles in cement-bone interface tissues expressed more cytokines mRNA than previously known to be related to periprosthetic bone resorption, and secreted metalloproteinases associated with extracellular matrix degradation and fibrosis.

Journal of Sleep Medicine 2018;15(2):62-67
OBJECTIVES: Restless leg syndrome (RLS) is a common sensorimotor disorder and is frequently associated with periodic limb movement in sleep (PLMS). Also about one third of patient with RLS have periodic limb movement during wakefulness (PLMW). However there is little research on the correlation between PLMW and RLS. We aimed to evaluate difference in sleep characteristics between patients with RLS with PLMW and those without PLMW. METHODS: Our study included twenty eight RLS patients. Subjects underwent suggested immobilization test (SIT) prior to one full-night polysomnography study. Patients were classified into two groups according to the presence of PLMW based on SIT-PLMW index. Polysomnographic findings, subjective sleep quality, and hematologic results were analyzed and compared between the two groups. RESULTS: Mean age of patient with frequent PLMW (SIT-PLMW ≥40/hr) was significantly higher. RLS patients with frequent PLMW were also significantly related to insomnia severity. The PLMS index was higher in patients with PLMW and showed a significant correlation with the PLMW index. CONCLUSIONS: PLMW influence sleep quality such as insomnia and is correlated with movement during sleep.

BACKGROUND: Tourniquet pain is probably mediated by C-fiber. The ability of fentanyl to interrupt this nociceptive conduction was studied by administering either fentanyl or saline intrathecally along with hyperbaric bupivacaine for spinal anesthesia. METHOD: The incidence of tourniquet pain was evaluated in 60 patients having orthopedic surgery of the lower extremities during spinal anesthesia by administering either 30 mcg fentanyl (group 2) or saline (group 1) along with 0.5% hyperbaric bupivacaine 10 mg. We measured the maximal sensory spread of analgesia to pinprick, the incidence of tourniquet pain, and the sensory anesthesia to pinprick at the onset of tourniquet pain. RESULTS: The average maximal sensory spread of analgesia was the same in both groups (T9). The incidence of tourniquet pain was significantly greater in group 1 (33%) than in group 2 (10%). The sensory levels of anesthesia at the onset of tourniquet pain were not different in two groups. CONCLUSIONS: Intrathecal fentanyl was effective against tourniquet pain for 2 hours of the orthopedic surgery of the lower extremities.
