Purpose: This research was implemented for men in their thirties who have lower back pain to observe general activity disorder patterns during pinch lift and rubbing manual therapy (PMT) and stretching application. Methods: Participants were divided into three groups: The PMT Group used applied pinch lift and rubbing manual therapy; the STR Group used applied stretching; and the CON Group was the control group. Participants for each group received treatments that were conducted three times a week for a total five weeks. Measures of pain utilized Visual Analogue Scale (VAS) [INCOMPLETE SENTENCE]. Results: There were significant differences between the PMT Group and the CON Group as well as the STR Group and the CON Group for pain, muscle strength and flexibility. There was a significant difference in pain between the PMT Group and the STR Group. Conclusion: As a result, it is inferred that PMT and stretching positively influenced recovery with regards to pain, muscle strength and flexibility relief; however PMT is more effective for pain relief than stretching.

This study was performed to determine the optimal dose of ozone for wound healing. Twenty Korean black goats were allocated to 4 groups. The skin wound with $1{\times}1cm$ was induced over the hoof. For 5 minutes per day, 0.1 ppm (Group I), 1 ppm (Group II) and 6 ppm (Group III) ozone gas was applied. In control group, 5 ml of normal saline was applied daily on the wound. Wound square was determined using color image analyzer at day 0, 4 and 14. Soft tissue depth of wound was determined using radiograph. Before the application of ozone gas, $1{\times}1cm$ of skin tissue was resected and observed for histopathologic findings. To determine the healing effect, $2{\times}1cm$ of wound tissue was resected and observed for histopathologic findings at day 14. In mean squares of wound, all experimental groups revealed more reduced mean squares than control group at day 4, and especially Group II (p<0.05) and Group III (p<0.05) revealed significant reduction. At day 14, Group I and Group II (p<0.05) revealed more reduced mean squares than control group, but Group III revealed less reduced mean squares than control group. In soft tissue depth of wound, all experimental groups and control group revealed swelling at day 4, compared with day 0. At day 14, all experimental groups and control group revealed reduction, compared with day 4, and especially Group II (p<0.05) revealed significant reduction. In histopathological findings, inflammation findings in epidermis and dermis, hemorrhagic finding in epidermis were revealed in control group. In Group I, inflammation finding was reduced, compared with control group. Formation of scab and many reepithelialization of epidermis were revealed. In Group II, inflammation findings in epidermis and dermis which were observed in control group were not found, normal skin tissue was revealed. In Group III, inflammation findings in epidermis and dermis were revealed, reepithelialization of epidermis was not founded. Slow healing process was observed, compared with Group I and II. It was concluded that Group II has excellent promotion effect of wound healing.

Exponential rise rate(ERR) of serum estradiol concentrations during active follicular phase was calculated for 49 ovulation induction cycles by human menopausal gonadotropin to know the ovulation induction outcome according to ERR classified into 3 groups with low, moderate and high ERR values(Group I${\leqq}$0.3, 0.3${\leqq}$0.6，Group III>0.6). The results were summarised as follows : 1. No significant difference in the dosage of human menopausal gonadotropin was identified in each group. 2. The mean serum estradiol concentration at the day of human chorionic gonadotropin injection in Group II and Group ill was significantly higher than that in Group I . 3. The mean diameter of leading follicles at the day of human chorionic gonadotropin injection showed no significant difference in each group. 4. No significant difference in the ovulation rate was observed in relation to ERR. How ever, 20% and 20.8% of pregnancy rate in Group I and Group II were achieved while no pregnancy was occurred in Group III. 5. The ovarian hyperstimulation frequency was significantly higher in Group ill that in Group I and Group II. In conclusion, the study suggests that exponential rise rate of serum estradiol is a useful tool in HMG ovulation induction by preventing ovarian hyperstimulation without reducing pregnancy success rate.

PURPOSE. This study was conducted to evaluate clinical validity of a zirconia full-coverage crown by comparing zirconia's wear capacity over antagonistic teeth with that of feldspathic dental porcelain. MATERIALS AND METHODS. The subject groups were divided into three groups: the polished feldspathic dental porcelain group (Group 1), the polished zirconia group (Group 2), and the polished zirconia with glazing group (Group 3). Twenty specimens were prepared from each group. Each procedure such as plasticity, condensation, and glazing was conducted according to the manufacturer's manual. A wear test was conducted with 240,000 chewing cycles using a dual-axis chewing simulator. The degree of wear of the antagonistic teeth was calculated by measuring the volume loss using a three-dimensional profiling system and ANSUR 3D software. The statistical significance of the measured degree of wear was tested with a significant level of 5% using one-way ANOVA and the Tukey test. RESULTS. The degrees of wear of the antagonistic teeth were $0.119{\pm}0.059\;mm^3$ in Group 1, $0.078{\pm}0.063\;mm^3$ in Group 3, and $0.031{\pm}0.033\;mm^3$ in Group 2. Statistical significance was found between Group 1 and Groups 2 and between Group 2 and 3, whereas no statistical significance was found between Group 1 and Group 3. CONCLUSION. Despite the limitations of this study on the evaluation of antagonistic teeth wear, the degree of antagonistic tooth wear was less in zirconia than feldspathic dental porcelain, representing that the zirconia may be more beneficial in terms of antagonistic tooth wear.

Background : This study was designed to evaluate the continuous effects of single intravenous injection of antiemetics on nausea and vomiting during continuous morphine injection for postoperative pain control. Methods : Prior to the study, we divided patients into two major groups according to the type of surgery performed intra-abdominal(Open: O) and non intra-abdominal(Close: C). When patients regained orientation after routine general anesthesia, enflurane-$O_2-N_2O$, we injected bolus dose of morphine and started continuous injection of morphine for postoperative pain control(Group I; Control). After bolus injection and just before continuous injection, we injected single dose of droperidol(Group II) or ondansetron(Group III). Mean arterial blood pressure, heart rate, pain score and symptom-therapy score were checked at 10 minutes, 4, 8, 16, 24, 36 hours after continuous morphine injection. Results : The pain score of group III was lower than group II(10 min.) and group I(24, 36 hours) in the open group. Symptom-therapy score of group III(10 min., 4, 24 hours) and group II(10 min.) were lower than group I in the open group. In the close group, symptom-therapy score of group III(8 hours) was lower than group I. Conclusions : Single intravenous injection of antiemetics have a tendency of lowering symptom-therapy score for 36 hours in spite of their relatively short elimination half-life.

Objective : The aim of the study was to review the clinical and radiological findings of those non-functioning adenomas[NFAs] with positive immnoreactivity for anterior pituitary hormones. Methods : Sixty patients with pituitary adenoma were treated at the author's institution between January 2000 and July 2005. All consecutive patients were underwent transsphenoidal surgery by same operator. In addition to the routine histopathological examination, surgical specimen was examined by immunohistochemical staining against adenohypophyseal cells. And clinical analysis was performed by retrospective review of medical records, neuroimaging examinations and immunohistochemical technique. We classified these pituitary adenomas into functioning adenomas [group F], immuno-positive NFAs [group S, so-called silent adenoma] and immuno-negative NFAs [group N], and compared clinical and radiological differences between group F, N, and S. Results : Of the 60 cases, group F was 25, group S was 25, and group N was 10. Among the group S, 5 cases showed reactivity against PRL, 1 against GH, 1 against both PRL and GH, 1 against TSH and GH, 2 against ACTH, 11 against FSH and 4 against both LH and FSH. Radiologically, invasiveness was noted in 8 in group S, compared to 3 in group N and 1 in group F [p = 0.02]. Intratumoral bleeding was noted in 7 of group S, 2 of group N and 2 of group F [p >0.05]. Conclusion : Silent adenomas were thought to behave more aggressive than other subgroups of pituitary adenomas. And so we suggest the immunohistochemical study against adenohypophyseal cells may be helpful for evaluating clinical course of pituitary adenoma, expecially for, NFAs.

The pile group foundation is widely used for gravity pier of high-speed railway bridges in China. If a moderate or strong earthquake occurs, the pile-surrounding soil will exhibit obvious nonlinearity and significant pile group effect. In this study, an improved pushover analysis model for the pile group foundation with consideration of pile group effect is presented and validated by the quasi-static test. The improved model uses simplified springs to simulate the soil lateral resistance, side friction and tip resistance. PM (axial load-bending moment) plastic hinge model is introduced to simulate the impact of the axial force changing of pile group on their elastic-plastic characteristics. The pile group effect is considered in stress-stain relations of the lateral soil resistance with a reduction factor. The influence factors on nonlinear characteristics and plastic hinge distribution of the pile group foundation are discussed, including the pier height, longitudinal reinforcement ratio and stirrup ratio of the pile, and soil mechanical parameters. Furthermore, the displacement ductility factor, resistance increase factor and yielding stiffness ratio are provided to evaluate the seismic performance of soil-pile system. A case study for the pile group foundation of a railway simply supported beam bridge with a 32 m-span is conducted by numerical analysis. It is shown that the ultimate lateral force of pile group is not determined by the yielding force of the single one in these piles. Therefore, the pile group effect is essential for the seismic performance evaluation of the railway bridge with pile group foundation.

Background: Postoperative nausea and vomiting (PONV), postanesthetic shivering and pain are common postoperative patient complaints that can result in adverse physical and psychological outcomes. Some antiemetics are reported to be effective in the management of postoperative pain and shivering, as well as PONV. We evaluated the efficacy of dexamethasone added to ramosetron on PONV, shivering and pain after thyroid surgery. Methods: One hundred and eight patients scheduled for thyroid surgery were randomly allocated to three different groups: the control group (group C, n = 36), the ramosetron group (group R, n = 36), or the ramosetron plus dexamethasone group (group RD, n = 36). The patients were treated intravenously with 1 and 2 ml of 0.9% NaCl (group C); or 2 ml of 0.15 mg/ml ramosetron plus 1 ml of 0.9% NaCl (group R); or 2 ml of 0.15 mg/ml ramosetron plus 1 ml of 5 mg/ml dexamethasone (group RD) immediately after anesthesia. Results: Incidence of nausea and the need for rescue antiemetics, verbal rating scale (VRS) 1 hour pain value, ketorolac consumption, and incidence of shivering were significantly lower in group R and group RD, than in group C (P < 0.05). Moreover, these parameters were significantly lower in group RD than in group R (P < 0.05). Conclusions: Combination of ramosetron and dexamethasone significantly reduced not only the incidence of nausea and need for rescue antiemetics, but also the VRS 1 hour pain value, ketorolac consumption, and the incidence of shivering compared to ramosetron alone in patients undergoing thyroid surgery.

This study was performed to investigate the chemical composition, mineral status, oxidative stability, and texture attributes of dry-cured ham from pigs fed processed sulfur (S, 1 g/kg feed), and from those fed a basal diet (CON), during the period from weaning to slaughter (174 d). Total collagen content and soluble collagen of the S group was significantly higher than that of the control group (p<0.05). The pH of the S group was significantly higher than that of the control group, whereas the S group had a lower expressible drip compared to the control group. The S group also showed the lower lightness compared to the control group (p<0.05). In regard to the mineral status, the S group had significantly lower Fe²⁺ and Ca²⁺ content than the control group (p<0.05), whereas the proteolysis index of the S group was significantly increased compared to the control group (p<0.05). The feeding of processed sulfur to pigs led to increased oxidative stability, related to lipids and pigments, in the dry-cured ham (p<0.05). Compared to the dry-cured ham from the control group, that from the S group exhibited lower springiness and gumminess; these results suggest that feeding processed sulfur to pigs can improve the quality of the texture and enhance the oxidative stability of dry-cured ham.
