In order to determine effects of molinate mixture granular formulations on release rate and weed control efficacy of herbicides and growth of rice plants, zeolite impregnation, slurry, and sand-coating granules were tested in laboratory and greenhouse. Release rate of molinate and simetryn was faster in sand-coating granule than in zeolite impregnation and slurry type granules. Mixture granular formulations of molinate/simetryn or molinate/simetryn/MCPB showed good weed control efficacy and this trend was more remarkably shown in sand-coating granule. Sand-coating granule more inhibited growth of rice plants compared to zeolite impregnation and slurry type granules.

Background: Idiopathic sudden sensorineural hearing loss(ISSHL) has been generally defined as an abrupt loss of auditory acuity without precipitating factors. Since ISSHL was first described as a disease entity, numerous reports assessing a variety of treatment regimens have been published. But its etiology, pathogenesis, treatment, and prognosis are controversial at the present time. Stellate ganglion block(SGB) has been used for the treatment of ISSHL by vasodilatation and increased blood flow to the inner ear. Methods: We reviewed the records of 152 patients to investigate the efficacy of SGB for ISSHL. The control group was managed with medications such as hypaque, heparin, steroid, nicotinic acid, and vitamins. The SGB group was managed with SGB and the same medications. SGB was performed with 8 ml of 1.0% mepivacaine. The efficacy of treatment was evaluated by pure-tone average following therapy. The recovery of hearing was defined as Siegel's criteria I, II, or III. Results: The recovery rate of the SGB group was higher than that of the control group(61.5 vs. 42.9%, p<0.05). The recovery rate was higher in patients who were treated early, within 7 days from the onset of symptoms, especially in the SGB group(79.7%). And in the case that initial hearing loss was severe (>70dB), the SGB group had a higher recovery rate(64.2%) than the control group(42.5%). Conclusions: SGB is thought to be a useful therapy for ISSHL, especially in the patients who were treated soon after onset or whose initial hearing loss was severe.

Objective: The long-term efficacy of microwave hyperthermia combined with chemoradiotherapy in treating nasopharyngeal carcinoma (NPC) with metastatic foci in cervical lymph nodes was evaluated. Methods: A total of 154 cases of N2 or N3 stage NPC were randomized into two groups: hyperthermia group (76 cases) and control group (78 cases). Both received cisplatin chemotherapy and radiotherapy. In addition, the hyperthermia group further received microwave hyperthermia to the metastatic cervical nodes with different patterns (before or after radiotherapy), heating temperatures (T90< $43^{\circ}C$ and $T90{\geq}43^{\circ}C$) and hyperthermia episodes (< 4 times, 4-10 times and > 10 times). Results: The 3-month and 5-year complete response (CR) rates of cervical lymph nodes in the hyperthermia group were significantly higher than those in the control group. The 5-year disease-free survival (DFS) rate and the 3-year / 5-year overall survival rate in the hyperthermia group were also significantly higher. There was no significant difference in 5-year metastatic rates. In the hyperthermia group, the 3-month and 5-year CR rates of T90< $43^{\circ}C$ treatment were significantly lower than with $T90{\geq}43^{\circ}C$ treatment. The CR rate was highest when the hyperthermia was performed 4-10 times. There were no significant differences in 3-month and 5-year CR rates between hyperthermia before or after radiotherapy treatment. Conclusion: Microwave hyperthermia combined with chemoradiotherapy can increase local control, DFS and 3, 5-year overall survival rates of patients with N2 ~ N3 stage NPC. The heating temperature should be over $43^{\circ}C$ with hyperthermia repeated 4-10 times.

Purpose: Information regarding antimicrobial prophylaxis (AMP) for gastric cancer surgery is limited. The present study investigated the efficacy of single-dose AMP for the prevention of surgical site infection (SSI) in patients undergoing gastrectomy for gastric carcinoma. Materials and Methods: Between 2011 and 2013, 1,330 gastric carcinoma surgery patients were divided into two AMP administration groups depending on the duration of treatment. Postoperative outcomes including morbidity and SSI were compared between the two groups overall and in matched patients. Risk factors for SSI were analyzed. Results: The extended group (n=1,129) received AMP until postoperative day 1 and the single-dose group (n=201) received single-dose AMP only during an operation. Postoperatively, there were no significant differences between the two groups with respect to overall morbidity, mortality, or length of hospital stay. The SSI rate of the single-dose group was not significantly different from that of the extended group overall (4.5% vs. 5.5%, respectively, P=0.556) or in matched patients (4.5% vs. 4.0%, respectively, P=0.801). There was no increase in the SSI rate of the single-dose group compared to the extended group in subgroups based on different clinicopathological and operative factors. Univariate and multivariate analyses revealed male gender, open surgery, and operating time (${\geq}180$ minutes) as independent risk factors for SSI. Conclusions: Single-dose AMP showed no increase in the postoperative SSI rate compared to postoperative extended use in patients undergoing gastrectomy for gastric carcinoma. The efficacy of single-dose AMP requires further investigation in randomized clinical trials specific to gastric cancer surgery.

The adolescent birth rate has doubled in the recent decade. As a result, the Korean government has implemented support for adolescent single-parent families by expanding the scope of coverage of the Single-parent Family Support Act in 2010. In order to understand whether experiences of facility entry programs and the Single-parent Family Support Act for adolescent single-parents were helpful or not, this study verified the relationship to mental health. This study utilized a part of the National Youth Policy Institute's 'Research on the Actual Condition of the Adolescent Pregnancy, Birth and Rearing Children.' Participants of the study were 218 adolescent single-parents at the age of 24 and younger. This study used the research methods of descriptive statistical analysis, ${\chi}^2$test, t-test, and one-way analysis of variance. The findings and discussion of this study are as below: Firstly, the depression level of adolescent single-parents who had been raised by grandparents was higher than other family types to a meaningful standard and adolescent single-parent's cognition of the original family's economic level was related to self-esteem and parenting efficacy. Secondly, the practical single-parent family support policy for adolescent single-parent's pregnancy, birth and rearing children has shown a higher reception rate, and medical service of facility entry programs has a higher satisfaction level. However, some of the facility entry programs and the Single-parent Family Support Act have a low reception rate and it should be considered whether to maintain them or not.Lastly, parts of facility entry programs and the Single-parent Family Support Act for adolescent single-parents have increased self-esteem and parenting efficacy and reduced parenting stress and depression's levels.

The aim of this study was to investigate the efficacy of Lactobacillus spp. W44 and J124 strain isolated from Kimchi on the growth rate, average daily gain (ADG), feed conversion and change of intestine microflora in the weaning piglets. In the experiment 1, growth rate was significantly increased to $28.5\;{\pm}\;4.3\;kg$ and $27.6\;{\pm}\;3.3\;kg$ after oral administration of W44 and J124 strain as feed additives, respectively (p<0.05). ADG and feed conversion were also significantly improved after administration during 44 experiment days (p<0.05). In the analysis of intestinal microflora, the number of Lactobacillus spp. in the experiment groups was significantly increased 100 to 1,000 times compared to those of control group. In the experiment 2, the efficacy of W44 and J124 strains on the growth rate, ADG, feed conversion and change of intestine microflora were reconfirmed significantly (p<0.05). However, there were no significant differences on feed conversion in the W44 bead and J124 bead groups. In summary, our results suggest that W-44 and J-124 stains from Kimchi have a significant effect on the weight gain and feed conversion, and it may be useful probiotic strains for the weaning piglets as feed additives.

Objectives : To evaluate the effectiveness of Chuna Manual Therapy for adhesive capsulitis by a systematic review manner. Methods : Five foreign electronic databases (Pubmed, Ovid-medline, Embase, Cochrane library, Chinese Academic Journals (CAJ)) and two Korean medical electronic databases (Oriental Medicine Advanced Searching Integrated System (OASIS) and Research Information Sharing Service (RISS)) were searched to find all randomized controlled trials (RCTs) using Chuna Manual Therapy as a treatment for adhesive capsulitis. The methodological quality of each RCT was assessed using the Cochrane risk of bias tool. Results : Twenty-one RCTs met our inclusion criteria. The meta-analysis showed positive results on the use of Chuna Manual Therapy combined with acupuncture or exercise therapy in terms of the efficacy rate and pain using the Visual Analogue Scale (VAS), compared to acupuncture or exercise alone [SMD-1.81 (95% CI & -2.54, -1.08), P<0.001, RR 1.19 (95% CI 1.14, 1.23), P<0.001)]. Positive results in terms of efficacy rate were also obtained comparing Chuna Manual Therapy to acupuncture alone [RR 1.10 (95% CI 1.02, 1.18), P=0.01]. Conclusions : Our systematic review found favorable results on the effectiveness of Chuna Manual Therapy for pain and efficacy rate of adhesive capsulitis. However, evidence was limited due to the lack of well-designed RCTs. More qualified clinical trials are needed to obtain stronger evidence.

The chemotherapeutic efficacy of trimethoprim-sulfamethoxazole ($Bactrim^{\circledR}$) in mice experimentally infected with Toxoplasma gcndii was evaluated. The average survival days and survival rate of mice infected intraperitoneally with $1{\times}10^5$ trophozoites and treated with $Bactrim^{\circledR}$ were compared with those of untreated group. The hematologic findings of blood samples of experimental mice were observed for comparison of side elects between $Bactrim^{\circledR}$ and pyrimethamine ($Daraprim^{\circledR}$), the latter of which has been one of the favorable drugs for the treatment of toxoplasmosis. The results are summarized as follows: 1. $Bactrim^{\circledR}$ showed a strong evidence of potent anti-Toxoplasma activity. The survival rate of mice administered with 24 mg of $Bactrim^{\circledR}$ per mouse per day for 7 days, was 83.3%, and the rate was increased to 100% in mice administered with two-fold concentrated dose of the drug. 2. The average numbers of white blood cells (W.B.C.) in the mouse groups treated with $Bactrim^{\circledR}$ or $Daraprim^{\circledR}$ were more increased than those only infected with T. gondii. The mice treated with $Daraprim^{\circledR}$ however, showed remarkably decreased numbers of W.B.C. as compared with those treated with $Bactrim^{\circledR}$ . 3. The average numbers of red blood cells (R.B.C.) and platelets both in the drug-treated and untreated T. gondii-infected mice were decreased as compared with normal mice. The numbers of R. B. C. in $Daraprim^{\circledR}-treated$ mice, however, were more decreased than in $Bactrim^{\circledR}-treated$ mice. 4. The average levels of hemoglobin both in the drug.treated and untreated T. gondii-infected mice were decreased, compared with normal mice. But there was no difference in the levels of hemoglobin between $Bactrim^{\circledR}$ and $Daraprim^{\circledR}-treated$ groups. In conclusion, trimethoprim.sulfamethoxasole ($Bactrim^{\circledR}$) was proven to be effective and safe for the treatment of murine toxoplasmosis. The efficacy was comparable with pyrimethamine ($Daraprim^{\circledR}$), but bone marrow depression was less severe with $Bactrim^{\circledR}$ treatment.

Purpose: The aim of this study was to analyze the efficacy and to estimate the complication rate of incontinence surgery according to the surgeon's specialty and whether a preoperative urodynamic study (UDS) was performed, using a nationally representative dataset. Methods: We enrolled 356,155 women over 20 years old who had undergone surgery for stress urinary incontinence between 2006 and 2015. Patients were followed for up to 3 years to analyze the reoperation and complication rates. Data were obtained from the National Health Claims Database of the National Health Insurance Service (NHIS) of Korea. Multiple Cox regression analysis was conducted to examine the efficacy and safety of incontinence surgery according to the surgeon's specialty and whether a preoperative UDS was performed. Results: The hazard ratio (HR) for reoperation was significantly higher for procedures performed by nonurologists than for procedures performed by urologists (HR, 1.174; 95% confidence interval [CI], 1.103-1.249). Acute urinary retention, postoperative infections, procedure-associated pain, and other complications were also more common in procedures performed by nonurologists than in those performed by urologists. When stratified by whether a preoperative UDS was performed, the HR for reoperation according to the surgeon's specialty varied by performance of a preoperative UDS. While the reoperation rate was significantly higher in procedures performed by non-urologists when a preoperative UDS was performed (HR, 1.208; 95% CI, 1.122-1.3), there was no significant difference in the HRs for reoperation according to specialty when a preoperative UDS was not performed. Conclusions: This population-based study showed that the postoperative outcomes of incontinence surgery were dependent upon the surgeon's specialty and that the reoperation rate according to the surgeon's specialty varied based on whether a preoperative UDS was performed.

Objectives: The purpose of this study was to assess the effects of moxibustion treatment for Cardiac arrhythmia through a systematic review. Methods: Electronic database including Cochrane library, Pubmed, China National Knowledge Infrastructure, Embase, DBpia, and Korean studies Information Service System were searched by combining the keywords such as "arrhythmias", "cardiac arrhythmias", "心律失常", "moxibustion" and "艾灸". Through the searching, 5 randomized controlled trials(RCTs) were included except animal testing and cellular experiment etc. The quality of each RCTs was assessed using the Cochrane risk of bias tool. Results: We included 5RCTs involving 468 participants. Two RCTs compared moxibustion versus conventional treatment, another RCT compared moxibustion plus acupuncture versus conventional treatment, another RCT compared moxibustion plus herbal medicine verus conventional treatment, the other RCT compared moxibustion plus herbal medicine and ointment versus conventional treatment. These studies were evaluated by the efficacy rate of treatments. Studies measured outcomes in efficacy, heart rate, electrocardiogram and symptoms. Each of 5 trials statistically showed a significant differences in efficacy rate. One study reported about side effects and another study reported about complications. The overall risk of bias was unclear in 5 studies. Conclusions: The evidence suggests that moxibustion treatment may help to reduce cardiac arrhythmia, however, it is limited, low-certainty and we cannot rule out benefits or risks with this treatment. High-quality studies that report adverse effects are needed.
