The present study was carried out to investigate the estrous behavior and vaginal smear after induction of estrus with exogenous hormones in the premature, metestrous and anestrous bitches. A total of 21 bitches(Mixed breed: 16, Jindo breed: 5), from 10 months to 5 years of age and weighing 8 to 15 kg was studied the change of vaginal smear and the estrous behavior before and after induction of estrus. The results obtained are as follows: 1. In the treatment A(They were given the $PGF_2{\alpha}$, estrone, estradiol-$17{\beta}$, PMSG and HCG) proestrus commenced in $10.16{\pm}1.44$($Mean{\pm}SEM$) days after treatment, The mean duration of proestrus, and estrus was $7.50{\pm}1.44$ and $13.50{\pm}3.44$ days, respectively. In the treatment B(They were given the PMSG and HCG) proestrus commenced in $5.53{\pm}0.59$ days after treatment. The mean duration of proestrus and estrus was $6.60{\pm}0.71$ and $14.60{\pm}1.14$ days, respectively. 2. All of the 6 bitches in the treatment A showed vulval swelling and vaginal discharge, 14 of the 15 bitches in the treatment B showed vulval swelling and vaginal discharge. However, all of the treatment A and B showed male acceptance. 3. The main change of vaginal smear in proestrus and estrus after induction of estrus was a increase in the proportion of anuclear and superficial cells associated with a decrease in small intermediate and parabasal cells. By the estrous behavior and vaginal smear the estrus was induced in all the premature, metestrous and anestrous bitches.
After initial structure of AISI 9260 steel is changed into pearlite and martensite, one is isothermally annealed at $700^{\circ}C$ below of $A_1$ transformation point and the other is isothermally annealed at the same condition after 3 cycles of heating and cooling between $680^{\circ}C$ and $780^{\circ}C$ of $A_1$ transformation point. Analyzing the changes of microstructure, mechanical properties and fractography of tension test, we obtained result as follows. The fastest spheroidization rate by changes of initial structure and heat treatment cycles is appeared at the heat treatment cycle which is isothermally annealed after 3 cycles of heating and cooling at below and above $A_1$ transformation point for martensite. At the above condition, the perfect spheroidization structure is appeared after 60hrs and after then, globular carbide is being coarsened. The mean diameter of globular carbide is $2.4{\times}10^{-3}mm$ after 90hrs. The changes of tension strength during spheroidization heat treatment follows Orwan function, ${\sigma}_o={\sigma}_i+Gb/l$, where l is interspacing of carbide particles and at the above condition, ${\sigma}_o=70.48+2.5{\times}10^{-3}/l(kg/mm^2)$. Fractography of fracture of spheroidization structure in tension test is appeared as dimple which is ductile rupture type by nucleation and growth of void, size of dimple is larger and deeper with increasing of heat treatment time.
We studied the effects of soy isoflavone supplements on bone metabolism marker (serum osteocalcin, urinary deoxypyridinoline) and urinary mineral excretion (urinary Ca, Mg, Zn) in 47 postmenopausal women. There were 24 participants in the treatment group and 23 in the control group. The treatment group consumed isoflavone extract capsules daily (which contained 90 mg of soy isoflavones) for 12 weeks. The study compared before and after isoflavone intake in the following areas: Physical examination, diet survey, bone metabolism marker and urinary mineral excretion. The average age of the treatment group was 64.6 years and that of the control group was 66.5 years. There were no significant differences between the two groups in terms of height, weight and body mass index. Both groups maintained a regular diet pattern in terms of their average daily nutrient intake. There were no significant differences between the treatment group (23.9 mg) and the control group (25.4 mg) in terms of daily isoflavone intake based on diet. The analysis of bone metabolism marker changes in the treatment group after 12 weeks of taking the isoflavone supplements demonstrated significant differences in the following: Serum osteocalcin (13.7 ng/mL in befor versus 6.8 ng/mL in after) and urinary deoxypyridinoline (5.9 nmol/mmol Cr in befor versus 4.5 nmol/mmol Cr in after). The subjects in the treatment group showed no significant difference in urinary Ca excretion. But the subjects showed a significant difference in urinary Mg (131.9 mg/day in befor versus 115.6 mg/day in after) and Zn (400.5 $\mu\textrm{g}$/day in befor versus 310.2 $\mu\textrm{g}$/day in after) excretion in the isoflavone treatment group at the levels of p<0.001, p<0.01, respectively. No changes were made in the intake of minerals. The composition of serum osteocalcin and urinary deoxypyridinoline, and indicators of bone metabolism, including the excretion Mg and Zn, significantly decreased. As a result, bone mineral loss was lessened. (Korean J Nutrition 36(5): 476~482, 2003)
Purpose: The aim of this study was to evaluate alterations of papilla dimensions after orthodontic closure of the diastema between maxillary central incisors. Methods: Sixty patients who had a visible diastema between maxillary central incisors that had been closed by orthodontic approximation were selected for this study. Various papilla dimensions were assessed on clinical photographs and study models before the orthodontic treatment and at the follow-up examination after closure of the diastema. Influences of the variables assessed before orthodontic treatment on the alterations of papilla height (PH) and papilla base thickness (PBT) were evaluated by univariate regression analysis. To analyze potential influences of the 3-dimensional papilla dimensions before orthodontic treatment on the alterations of PH and PBT, a multiple regression model was formulated including the 3-dimensional papilla dimensions as predictor variables. Results: On average, PH decreased by 0.80 mm and PBT increased after orthodontic closure of the diastema (P<0.01). Univariate regression analysis revealed that the PH (P=0.002) and PBT (P=0.047) before orthodontic treatment influenced the alteration of PH. With respect to the alteration of PBT, the diastema width (P=0.045) and PBT (P=0.000) were found to be influential factors. PBT before the orthodontic treatment significantly influenced the alteration of PBT in the multiple regression model. Conclusions: PH decreased but PBT increased after orthodontic closure of the diastema. The papilla dimensions before orthodontic treatment influenced the alterations of PH and PBT after closure of the diastema. The PBT increased more when the diastema width before the orthodontic treatment was larger.

Objectives : This study was performed to investigate the effect of simple acupuncture and electroacupuncture at Bai Hui($GV_{20}$) on heart rate variability in healthy adults with stress task. Methods : 40 healthy volunteers participated in this study. HRV was recorded before and after stress. And then simple acupuncture(SA group) was applied at $GV_{20}$ or electroacupuncture(EA group) was applied at the same spot in each treatment group for 20 minutes. No treatment was performed in control group for 20 minutes. Then HRV was recorded. Results : 1. In all groups, LF norm, LF/HF, HF norm showed significant changes after mental stress. 2. Control group showed no significant change. In SA group, HF norm LF, LF norm and LF/HF showed a significant change after treatment. In EA group, Mean HR, HF, LF norm, HF norm and LF/HF showed a significant change after treatment. In both treatment groups, there were significant differences after treatment compared to control group. 3. In EA group, HF and HF norm decreased significantly after treatment compared to SA group. Conclusions : These results suggest that simple acupuncture and electroacupuncture at $GV_{20}$ affect the balance of the autonomic nervous system and that electroacupuncture at $GV_{20}$ enhances parasympathetic activation more than simple acupuncture.
Objectives : The purpose of this study is to investigate the clinical effects of heating-conduction acupuncture therapy on ligament injury induced by acute ankle sprain. Methods : From september 16, 2008 to April 17, 2010, the 28 outpatients who had admitted to department of oriental rehabilitation medicine, Dae-Jeon oriental Medical hospital, Dae-Jeon university with acute ankle sprain were performed heating-conduction acupuncture therapy on anterior talofibular and calcaneofibular ligament injury. To evaluate the efficiency of heating-conduction acupuncture therapy, pain threshold with pressure algometer and visual analogue scale(VAS) were applied before treatment and after 1st, 2nd treatment. Results : 1. The pain threshold and the VAS score showed statistical significant improvement after 1st treatment on calcaneofibular and anterior talofibular ligament injury. 2. The VAS score after 2nd treatment on calcaneofibular and anterior talofibular ligament injury showed statistical significant improvement compared with that after 1st treatment. 3. The pain threshold after 2nd treatment on calcaneofibular and anterior talofibular ligament injury did not show statistical significant improvement compared with that after 1st treatment. 4. The difference between anterior talofibular and calcaneofibular ligament injury was not statistical significant in pain threshold and VAS score. Conclusions : Heating-conduction acupuncture therapy has clinical effects of pain reduction on patient with calcaneofibular ligament injury as well as anterior talofibular ligament induced by acute ankle sprain.
Purpose: Cholestasis resulting from cytomegalovirus (CMV)-induced hepatitis manifests in 40% of patients with a CMV infection. Ganciclovir treatment in children with CMV infections has proven to be highly effective. Until now, there are very few studies have identified predictive factors for liver biochemistry improvement after ganciclovir therapy. This study aimed to identify the predictors of liver biochemistry improvement in patients with CMV cholestasis after ganciclovir treatment. Methods: A retrospective cohort study was conducted using medical records from Dr. Sardjito General Hospital Yogyakarta, Indonesia from 2013 to 2018. CMV cholestasis was confirmed based on serum CMV IgG and IgM positivity and/or blood and urine CMV antigenemia positivity. Incomplete medical records and other etiologies for cholestasis, such as biliary atresia, choledochal cyst, metabolic diseases, and Alagille syndrome, were excluded. Patient age at cholestasis diagnosis and ganciclovir treatment, duration of CMV cholestasis, history of prematurity, central nervous system involvement, and nutritional status were analyzed and presented as an odds ratio (OR) with a 95% confidence interval (95% CI). Results: CMV cholestasis with ganciclovir therapy was found in 41 of 54 patients. Multivariate analysis showed that a shorter duration of CMV cholestasis (OR: 4.6, 95% CI: 1.00-21.07, p=0.04) was statistically significant for liver biochemistry improvement after 1 month of ganciclovir treatment. The remaining factors that were analyzed were not significant predictors of liver biochemistry improvement in patients with CMV cholestasis after ganciclovir treatment. Conclusion: A shorter duration of CMV cholestasis is the predictor of liver biochemistry improvement after 1 month gancyclovir treatment.
Purpose: This study evaluated the predictive role of fecal calprotectin (FC) measured at an early stage of treatment for monitoring clinical remission (CR) after six months and endoscopic remission (ER) after one year of treatment in pediatric Crohn's disease (CD). Methods: This retrospective study included 45 patients who simultaneously underwent ileocolonoscopy and FC testing during follow-up. FC levels were measured before and after six weeks of treatment. CR was assessed after six months of treatment using Pediatric Crohn' s Disease Activity Index and acute-phase reactants. ER was assessed after one year using the Simple Endoscopic Score for Crohn's Disease. Results: Twenty-nine (64.4%) patients used oral prednisolone for remission induction and 16 (35.6%) patients used anti-tumor necrosis factor-alpha. Thirty (66.7%) patients achieved CR, while 24 (53.3%) achieved ER. The FC level measured after six weeks of treatment could predict CR (χ2=9.15, p=0.0025) and ER (χ2=12.31, p=0.0004). The δFC could predict CR (χ2=7.91, p=0.0049), but not ER (χ2=1.85, p=0.1738). With a threshold of ≤950.4 ㎍/g, FC at week six could predict CR with 76.7% sensitivity and 73.3% specificity. The area under the curve (AUC) was 0.769 (standard error 0.0773, p=0.0005). The same threshold predicted ER with 87.5% sensitivity and 71.4% specificity. The AUC was 0.774 (standard error 0.074, p=0.0002). Conclusion: FC assay at an early stage of treatment can be used as a surrogate marker to predict CR and mucosal healing in pediatric CD.
Objectives : We implemented the Artemisia Extract Moxibustion Method and had the clinical tests for the diabetes with it. Methods : We implemented Artemisia extract made by extracting the vasodilator and antioxidant compounds from Artemisia-CH2C12 fraction and the moxibustion method constructed with DC Power supply, controller, Artemisia pad. single and multiple heating terminal with PTC(Positive Temperature Coefficient) thermistor. And we performed to estimate the efficiency on the questionnaire and the clinical tests with 23 cases of the diabetics. Results : We have estimated the improvement over 60% the symptoms that were the upper and lower limbs pain, frequent urination, spontaneous perspiration, thirst, decrease of body weight, and malaise after the moxibustion treatment on 5 cases among 23 cases. And the 19 cases took the biochemical check-up after the moxibustion treatment. From the results of biochemical check-up, the average HbAlc of before treatment was 8.400%, and after treatment 7.632%. The average HbAlc was decreased significantly after treatment (P<0.001). And the average urinary blood of before treatment was 0.73 and after treatment 0.27. The average urinary blood was decreased significantly after treatment (P<0.001). In addition the average FBS before treatment was 182.64 mg/dl, after treatment 161.77 mg/dl. Conclusions : We could estimate that our proposed moxibustion method was a significant treatment method for the diabetes.
The aim of this study was to assess change of the oral health related quality of life after fixed prosthetic treatment using implant therapy. One hundreds and twenty patients from 3 dental clinics in Seoul, Incheon and Daegu were recruited after verbal consent. The oral health related quality of life by OHIP-14, the treatment satisfaction by North Texas Periodontal Associates and the oral health interest w+ere measured before fixed prosthetic treatment using implant and one months after prosthetics. Total OHIP-14 changed significantly between pre- and post- treatment (p<0.001). Although gender(p=0.01), economic status (p=0.04) and education status (p=0.01) affect to OHIP-14 significantly before treatment, these factors didn't have effects on OHIP-14 after treatment. The subjective satisfaction in masticatory function, social function and psychological function increased significantly after treatment (p<0.001). Besides, the patients' oral health interests increased significantly after treatment (p<0.001). The fixed prosthetic treatment using implant therapy can improve the oral health related quality of life, subjective satisfaction of mastication, social function and psychological function, and oral health interest of dental patients.
