Detection of IgG antibody in clonorchiasis has been accomplished through various serodiagnostic procedure including complement fixation test, gel diffusion test, indirect fluorescent antibody test, indirect hemagglutination test etc. In this report enzyme immunoassay (ELISA) and indirect hemagglutination test (IHA) were used to determine IgG serum antibody levels before and after therapy with praziquantel. Briefly, sera from 62 cases of confirmed human clonorchiasis were examined before and after treatment with praziquantel. Among 62 cases treated 25 cases were categorized as completely cured groups by formalin-ether and careful examination of 4 cellophane thick smered slides at 18 months after treatment. The sera of 25 cases of cured groups were examined again by ELISA and IHA, and com-pared to the previous data. The results obtained were as follows; 1) Sensitivity of IHA test was 83.6% when cut-off titer of 1:8 was applied. No sera obtained from 10 normal healthy control showed positive reaction. 2) Twenty cases (80.0%) out of 25 cured one showed negative results by IHA at 18 months after treatment. 3) Although 5 cases showed positive titer even 18 months after treatment 3 cases of them showed decreased antibody titer. However 2 cases did not show any response. 4) Even though almost all cases showed de- creased ELISA value, only 11 cases (44.0%) out of 25 patients showed negative results by ELISA at 18 months after treatment. In conclusion, it is suggested that, while IgG ELISA for detecting long persisting antibody was more sensitive than IHA, IHA results more conclusively indicated effective treatment in clonorchiasis by negative conversion than did the results of ELISA.

Objectives Atypical antipsychotics show better treatment efficacy, safety and tolerability than typical antipsychotics. Among the adverse events observed during treatment with antipsychotics, extrapyramidal syndrome (EPS) and negative symptoms has been greatly reduced. But still, weight gain is receiving growing attention. The aim of this study was to investigate the association between therapeutic response to atypical antipsychotics and weight gain in admission status. Methods The study was conducted for Korean inpatients with schizophrenia in a university hospital in Seoul, between Jan 2006 and Dec 2010. Data was collected by reviewing the medical record of 39 consecutively hospitalized patients with Schizophrenia (DSM-IV) at a university hospital. Positive and Negative Symptom Scale (PANSS), Body Mass Index (BMI) and body weights were measured. Results No significant difference was observed for sex, age, illness onset age, family history of schizophrenia, numbers of hospitalization before treatment, educational years, marriage status, occupational status and subtype of schizophrenia between weight gainers and non-weight gainers. Regarding treatment response to atypical antipsychotics, weight gainers show significantly more PANSS decrease than non-weight gainers during admission period. Conclusions Our findings suggest that it appears to be more likely to respond to atypical antipsychotics in weight gainers than non-weight gainers (that weght gainers appear to be more likely to respond to atypical antipsychotics than non-weight gainers). These results show that the antipsychotic-induced body weight gain is associated with therapeutic response of antipsychotics in Korean inpatients with schizophrenia.

Objective: An experiment was conducted to determine the effect of superdosing phytase on productive performance and egg quality in laying hens. Methods: A total of 200 42-wk-old Hy-Line Brown laying hens were allotted into 1 of 5 dietary treatments with 5 replicates consisting of 8 hens per replicate. The positive control (PC) and negative control diets (NC) were prepared based on the recommended P levels in layer diets. Supplemental phytase was added to the negative control diet at 10,000 (SD10), 20,000 (SD20), or 30,000 (SD30) fytase units (FTU)/kg. Productive performance was summarized for 6 weeks from 42 weeks to 47 weeks of age. Egg quality was assessed from 4 eggs per replicate randomly collected at the conclusion of the experiment. Results: The SD20 treatment had greater (p<0.05) hen-day egg production than PC, NC, and SD10 treatment groups. There was no difference in hen-day egg production between SD20 and SD30 treatment groups. However, SD30 treatment had greater (p<0.05) hen-day egg production than PC treatment, but showed no difference in hen-day egg production as compared to NC and SD10 treatment groups. However, egg weight, egg mass, feed intake, and feed conversion ratio were not affected by dietary treatments. Egg quality including eggshell strength, eggshell color, egg yolk color, and haugh unit was not influenced by dietary treatments. Conclusion: Superdosing level of 20,000 FTU/kg phytase in diets has a positive effect on egg production rate, but no beneficial effect on egg quality in laying hens.

The positive margins after LEEP(loop electrosurgical excision procedure) in cervical intraepithelial neoplasia are generally considered to be a risk factor for the recurrence or persistence of CIN currently. When positive margin exists, secondary LEEP or hysterectomy is performed. The aim of this study was to observe effects of Traditional Korean Medicine treatment for patients with surgical margin positive after LEEP. It was conducted retrospective chart review for 4 patients with the surgical margin positive after LEEP, who were scheduled to have secondary LEEP 3 months later. Patients were treated with herbal medicine, pharmacopuncture and herbal liquid vaginal treatment. They were followed up by cytology, colposcopy, human papillomavirus DNA test and punch-biopsy at 1, 3 and 6 months. After 3 month of treatment, three patients did not need secondary LEEP because of normal cytology, negative HPV status and normal colposcopy, while the other patient underwent secondary LEEP because of ASCUS cytology and positive high-risk HPV. After 6 month of treatment, the other patient also had normal cytology, negative HPV status and normal colposcopy and had been in fifth week of pregnancy. This study suggest that Traditional Korean Medicine treatment may be an effective to the patients with surgical margin positive after LEEP in cervical intraepithelial neoplasia.

Seven flue-cured tobacco(Nicotiana tabacum) varieties and their 21 progenies in Fl and F2 generation, half diallel crosses(no reciprocal), were tested for the degree of heterosis and combining abilities in sucker producing character according to topping and suckering treatment. Significant difference in number and weight of sucker was observed among seven cultivars. The values of general combining ability(GCA) were greater than those of specific combining ability(SCA) in weight and number of sucker in F$_1$ generation. In topping and suckering plot, Cocker 86, McNair 944, and Va 115 revealed the significant negative GCA effects for number and weight of sucker, but By 104 and Speight G-28 did positive GCA. Without topping and suckering, GCA effects for sucker weight in Cocker 139 and Cocker 86 were negative and those for sucker number in Va. 115 were also negative. Negative SCA values in sucker weight could be observed in F$_1$ generation of Cocker 86 X BY 104 and Speiht G-28 X Cocker 86, in F$_2$ of Hicks $\times$ Speight G-28 and McNair 944 $\times$ BY 104 in topping and suckering plot. SCA in F$_1$ of McNair 944 X Cocker 86 and Speight G-28 X Cocker 139 was negative without topping and suckering. The value of heterosis in sucker producing character of F$_1$ hybrids was positive

The present clinical trial was performed to evaluate the anthelminthic effect and tolerance of Oxantel pamoate, a new antiwhipworm agent, in the treatment of T. trichiurus infection. Oxantel pamoate oral suspension was administered as a sing1e dose of 10 mg per kg. body weight to a total of 46 T. trichiurus infected cases selected out of 64 positives, by examining 89 fecal specimens collected from the soldiers and in-patients of xx Armed Forces General Hospital. For the evaluation, the negative conversion rate (cure rate) and the egg reduction rate were assessed 22 days after the treatment. The result obtained were as follows: 1. The prevalence rate of T. trichiurus infection in this study was 71.9%, while the mean E.P.G. of 46 treated cases was 126. 2. The egg negative conversion rate was 91.3%, and 98.4% of egg reduction rate was obtained. 3. From the observation of 107 worms expelled during 3 consecutive days after the treatment, it was known that sex ratio of male and female was about 1 : 2 and that average worm burden per capita was 2.3. 4. In all treated cases, the medication was readily accepted and well tolerated. On the hemograms, urinalysis and liver function tests, no significant differences were noted before and after the drug administration. There was also no detectable objective and subjective side effect.

The tensile property of A5082 and A6060 aluminium wrought alloys was investigated, in terms of the strain rate sensitivity on alloy conditions by heat treatment and bake hardenability on pre-strain prior to strain ageing. The tensile test was carried out in a range of strain rate of 4.17 × 10^-5 s^-1 ~ 4.17 × 10^-5 s^-1 in room temperature and the nominal range of pre-strain was 3.0 ~ 10.5%. The tensile deformation of A5082 alloys is characterized as typical case of dynamic strain ageing with negative strain rate sensitivity for all conditions, and the tensile strength indicates a similar level regardless of alloy conditions, except only in full annealed condition. The stress-relief annealing on A6060 alloys can induce practical decrease in strength level of over approximately 100 MPa without any ductility loss, compared to as-rolled condition, while a full annealed and aged condition leads remarkable strengthening effect with the decrease of tensile elongation. Additionally, the bake hardenability of A5082 alloy by strain ageing indicates a negative dependence upon the increase of pre-strain, while A6060 alloy exhibits a positive sign even in low level relatively compared with conventional SPCC.

Bovine mastitis, an inflammation of the mammary gland, is the most common disease of dairy cattle causing economic losses due to reduced yield and poor quality of milk. The etiological agents include a variety of gram-positive and gram-negative bacteria, and can be either contagious (e.g., Staphylococcus aureus, Streptococcus agalactiae, Mycoplasma spp.) or environmental (e.g., Escherichia coli, Enterococcus spp., coagulase-negative Staphylococcus, Streptococcus uberis). Improving sanitation such as enhanced milking hygiene, implementation of post-milking teat disinfection, maintenance of milking machines are general measures to prevent new cases of mastitis, but treatment of active mastitis infection is dependant mainly on antibiotics. However, the extensive use of antibiotics increased concerns about emergence of antibiotic-resistant pathogens and that led the dairy industries to reduce the use of antibiotics. Therefore, alternative therapies for prevention and treatment of bovine mastitis, particularly natural products from plants and animals, have been sought. This review provides an overview of bovine mastitis in the aspects of risk factors, control and treatments, and emerging therapeutic alternatives in the control of bovine mastitis.
