  • The objective of this research was to select effective fungicides for the control of Fusarium head bight (FHB) of wheat. We tested fourteen commercial fungicides against FHB in the laboratory and under field. Fludioxonil FS, Fludioxonil SC, and Benomyl + Thiram WP highly inhibited the mycelial growth of Fusarium graminearum on the medium while Oxine-copper WP, Thiophanate-methyl WP, and Copper hydroxide WP were not effective against FHB. To verify the disease control in field condition, we selected four fungicides such as Fludioxonil SC, Captan WP, Difenoconazole + propiconazole EC, and Metconazole SC. Their control efficacy on FHB disease severity of wheat was examined after the fungicide treatment twice (30th April and 10th May, 2012) in the two field locations (Iksan and Gimje). With no treatment, FHB severity was 45% and 33.7% in Gimje and Iksan, respectively. FHB disease incidence after fungicide treatment was between 0.3% and 2.2% in Gimje, showing over 95% FHB disease control. FHB disease incidence of fungicide-treated sector in Iksan showed slightly higher than Gimje but the control value of fungicides exhibited 87-90%. No side effect of the chemicals was observed in fungicide treatment. These results showed that four fungicides were effective in the FHB disease control in wheat.

  • Background : The aim of this study was to analyze the clinical manifestations and efficacy of treatment regimens in order to determine the adequate combination of anti-tuberculotic agents and duration of treatment for tuberculous lymphadenitis. Methods : We made a review of 373 patients with tuberculous lymphadenitis, who were admitted to four medical college hospitals in Taegu Korea from 1989 to 1998, and their diagnoses were confirmed histologically and bacteriologically. Results : The incidence of tuberculous lymphadenitis was 71.3% in women and 57.7% were between the ages of 20 and 39 years. The most common symptom was painless swelling. The most commonly involved lymph nodes were unilateral superficial cervical lymph node groups. Tuberculous lymphadenitis was accompanied with active pulmonary tuberculosis, commonly. The sensitivity of fine needle aspiration(FNA) in tuberculous lymphadenitis was 79.6%, and 92.2% of the patients had a strong positive reaction to the tuberculin skin test. The most commonly prescribed anti-tuberculotic regimen was the combination of INH, RMP, EMB, and PZA(62.6 %). Eighty percent of patient were treated for 9-12 months. There was no significantly difference in the recurrence rate of tuberculous lymphadenitis between the combinations of anti-tuberculotic agent, including INH and RMP, and between the durations of treatment, for a period of 6 months of more. Conclusion : The combination of FNA cytologic examination and tuberculin skin test may be helpful in the diagnosis of tuberculous lymphadenitis. We propose that the combination of anti-tuberculotic agents, INH, RMP, EMB, and PZA, be prescribed to patients for 6 to 9 months.

  • Background : Interferon-gamma (IFN-${\gamma}$) is a critical cytokine in the defense against a Mycobacterium tuberculosis infection. Even though IFN-${\gamma}$ has occasionally been used in the treatment of refractory multidrug-resistant tuberculosis (MDR-TB) with some promising results, there is still some controversy regarding the therapeutic efficacy of IFN-${\gamma}$. This study was performed to examine the effect of subcutaneous IFN-${\gamma}$ in the treatment of MDR-TB patients. Methods : Six patients with refractory MDR-TB were enrolled in this study. Two million IU of IFN-${\gamma}$ was administered subcutaneously three times a week with the concomitant administration of antituberculous drugs for at least for 28 weeks. During the IFN-${\gamma}$ therapy, the sputum smear and culture, radiological and clinical evaluations were performed every 4 weeks throughout the study period. Results : The mean age of the 6 patients was 37 years (ranges, 15-61 years). The drug susceptibility test to standard antituberculous drugs revealed resistance to an average of 6.8 (${\pm}1.2$) agents including isoniazid and rifampicin. An average of 10.8 (${\pm}1.3$) antituberculous drugs were prescribed before IFN-${\gamma}$ therapy. The culture became negative in 2 patients (33%) after initiating IFN-${\gamma}$ therapy; one at 8 weeks, and the other at 24 weeks. Finally, after stopping the IFN-${\gamma}$ therapy after 28 weeks, the culture became positive again in the two patients who were culture-negative. The other 4 patients who failed in the culture conversion are still on antituberculous treatment except for one who died of tuberculosis. Conclusion : Even though 28 weeks of subcutaneous IFN-${\gamma}$ therapy in combination with antituberculous drugs was successful in inducing the culture-negative conversion in some patients with refractory MDR-TB, the culture became positive again after stopping the IFN-${\gamma}$ therapy. This suggests that subcutaneous IFN-${\gamma}$ therapy may have suppressive effect on tuberculosis only during the IFN-${\gamma}$ therapy period in some patients. Further studies will be needed to determine the optimum dose, the administration route, the duration of therapy, and the predicting factors of the response to adjuvant IFN-${\gamma}$ therapy.

  • In Korea, Clonorchis sinensis infection is still highly prevalent because case detection in the field is difficult and the detected cases used to be incompletely cured due to treatment failure. The present study tried to control clonorchiasis in an endemic village by repeated treatments with praziquantel every 6 months and to evaluate sonography as a diagnostic measure. By stool examinations, the egg positive rate in the endemic village was 22.7%, but it decreased to 19.6% at 6 months. 15.1% at 12 months, 12.2% at 18 months, 6.3% at 24 months, 11.4% at 30 months, and 6.3% at 42 months after the beginning of repeated praziquantel administration. The sonography showed 61 (49.6%) positive cases of 123 screened residents; among egg-positives the sonography positive rate was 52.2% and among egg-negatives it was still 49%. The rate among cured cases was 64.3% after 6 months, 50.0% after 12 months, 50.0% after 18 months, and 66.7% after 24 months. In a non-endemic village, 64 residents were found egg-negative by fecal examination, but 20 (31.3%) of them were positive by sonography. The present findings indicate that control of clonorchiasis in an endemic village by repeated praziquantel treatment for 42 months is still insufficient and sonography is of little value for diagnosis of clonorchiasis.

  • Purpose : Rotavirus is an enteric pathogen that affects millions of children globally each year. But no specific therapy is available for the management of rotavirus diarrhea. Due to the clear need to define improved modality for treatment of rotavirus diarrhea, we evaluated the efficacy of antirotavirus IgY in the treatment of infants and children with gastroenteritis. Methods : First, the amount of viral particle in the stools of thirteen patients(seven were given IgY, 6 placebo) infected by rotavirus were evaluated for 3 days with the quantitative RT-PCR method. Second, 36 children with known rotavirus infection identified by ELISA or semi-quantitative RT-PCR were evaluated. We gave 5 g anti-rotavirus egg yolk daily in two equally divided doses for 3 days to two groups(an 18 IgY group and an 18 placebo group), respectively after parenteral consent. Daily vomiting frequency, stool frequency, oral intake and urine output were monitored for 3 days, and electrolyte and blood chemistry were checked at the first and third days. Results : First, in the placebo group, the amount of virus particles increased daily, but in the IgY group it decreased daily. Second, when IgY and placebos were given to children infected with rotavirus, diarrhea on the third day decreased significantly in the IgY group, compared with the placebo group. Conclusion : Treatment with antirotavirus immunoglobulin from immunized chicken's egg resulted in a decrease in the amount of viral particles in stools and diarrhea frequency in children. These results suggest that anti-rotavirus IgY is effective in the treatment of rotavirus gastroenteritis.

  • [ $\underline{Purpose}$ ]: We performed this prospective randomized study to evaluate the efficacy and the complications of radiotherapy for Subfoveal CNV in ARMD and to compare the treatment results at two dosages (14.4 Gy and 19.8 Gy). $\underline{Materials\;and\;Methods}$: 60 eyes of 55 patients were enrolled, and randomized into 14.4 Gy (31 eyes) or 19.8 Gy (29 eyes) groups. CT was used to plan the radiotherapy. All patients received radiotherapy with a 1.8 Gy daily dose using 4 MV photon. We categorized treatment results as improved, stable, or deteriorated based on visual acuity changes of more than 2 lines on the ETDRS chart. $\underline{Results}$: Median follow-up period was 33.5 months. At 12 months, visual acuity improved in 9 (16.7%), stable in 41 (75.9%), and aggravated in 4 (7.4%) of 54 evaluated eyes. At 24 months, 49 eyes (81.7%) were evaluated. Visual acuity improved in 6 (12.2%), was stable in 33 (67.4%), and deteriorated in 10 (20.4%). At 36 months, 37 eyes were evaluated. Six (16.2%) eyes were improved, 21 (56.8%) stable, and 10 (27.0%) deteriorated. No significant difference in response was observed between the 14.4 Gy and 19.8 Gy groups (Mantel-Haenszel $x^2=0.4756$). The proportion of eyes with a vision of $20/100{\leq}increased$ from 28.3% initially to 32.7% after 24 months of radiotherapy. There were no severe acute or chronic complications. $\underline{Conclusion}$: External beam radiotherapy with doses of 14.4 or 19.8 Gy may be an effective treatment for subfoveal CNV in ARMD. No dose-response relationships with respect to treatment response or toxicity were observed between the 14.4 Gy and 19.8 Gy groups.

  • Background: The routine application of the combined regimen of corticosteroid-antituberculosis therapy to the tuberculous pleurisy remains controversial. Steroid therapy to tuberculous pleurisy could be effective on the acceleration of absorption of pleural effusion and symptom improvement, but there has been debate about the effect of prednisolone on the prevention of pleural adhesion. So we studied the efficacy of combined regimen of prednisolone-antituberculosis therapy on the absorption of pleural effusion and prevention of pleural adhesion. Method: A prospective, randomized study was performed in 82 patients, 50 patients(non-steroid group) were treated with only antituberculosis regimen for 6 months and in 32 patients(steroid group) prednisolone(30mg/day) were administered in addition to antituberculosis regimen for one months and tapered for another month. The amount of pleural effusion was compared at the beginning of treatment, 2nd month, 6th month and final visit with chest X-ray findings which were graded from grade 0(complete absorption) to grade 6(near total haziness). Results: The amount of pleural effusion of steroid group at 2nd month, 6th month and final visit was lesser than that of non-steroid group(P<0.05). The incidence of the complete absorption of the pleural effusion was 3/32(9.4%) in steroid group, 1/50(2%) in non-steroid group at 2nd month after treatment; and 12/32(37.5%) in steroid group, 6/50(12%) in non-steroid group at 6th month after treatment(P<0.05). At final observation, the incidence of residual pleural thickening was 15/32(47%) in steroid group and 37/50(74%) in non-steroid group(P<0.05). No serious side effects were noted during the treatment with prednisolone. Conclusion: The administration of prednisolone in conjunction with antituberculosis chemotherapy improved the absorption of pleural effusion and decreased the residual pleural thickening.

  • This study was conducted to investigate the effects of modification of a herbal recipe(Herb $Mix^{(R)}$) on the growth of pullet and laying performance of hens. The formula of Herb $Mix^{(R)}$, a mixture of Rehmannia glutinosa, Angelica gigas, Discorea japonica, Glycyrrhiza uralensis, Schisandra chinensis and Ligusticum jeholense, was modified in mixing ratio. A total of 1,120 pullets(Hy-Line Brown) of 14 wks old were assigned to seven treatments; control, Herb $Mix^{(R)}$(HM), R. glutinosa fortified HM, A. gigas fortified HM, D. japonica fortified HM, G. uralensis fortified HM, S. chinensis fortified HM, L. jeholense fortified HM and Flavomycin supplemented diet. Each treatment had 8 replicates of 20 birds each housed in 2 birds cages. Body weight at 10% egg production was significantly(P<0.05) influenced by treatments. Birds fed A. gigas fortified HM diet were heaviest followed by L. jeholense fortified HM, HM-original and D. japonica fortified HM, Flavomycin supplemented diet and R. glutinosa while those fed control diet were lightest. Also, age reaching 50% egg production and peak production was earliest in A. gigas fortified HM and latest in the control. Egg production, feed intake, feed conversion and egg weight were significantly influenced by treatments. Significant improvement in egg production and feed intake was shown in A. gigas fortified HM treatment. Feed conversion ratio was lowest in antibiotic(Flavomycin) treatment and egg weight was heaviest in L. jeholense fortified HM treatment. There were no significant differences among treatments in intestinal microflora but cfu of Cl. perfringnes and E. coli tended to be lower in HM treatments than the control. Among the leucocytes of blood, the HM treatments were lower than the control in counts of white blood cell and heterophils. It was concluded that modification of Herb $Mix^{(R)}$ fortifying with A. gigas, D. japonica and L. jeholense significantly influence growth and laying performance of birds.

  • Background: Paraquat is known to induce oxidant injury that results in multiorgan failure and lung fibrosis. Iron has been considered to play a key role in paraquat-induced oxidant lung injury. This study examined the effect of deferoxamine, an iron-chelating agent, in the treatment of paraquat poisoning. Methods: From September, 2001 to April, 2005, 28 patients with paraquat poisoning who were admitted at a medical intensive care unit of a University-affiliated hospital, were enrolled in this study. Sixteen patients were treated according to the paraquat poisoning treatment guidelines and 12 received an intravenous infusion of deferoxamine in addition to the treatment guidelines. Results: There were no differences between the two groups in terms of age, gender, severity of paraquat poisoning, and the time elapsed from ingestion to presentation at hospital. There was no difference in overall mortality between the two groups but the incidence of respiratory failure in the deferoxamine group was higher than in the conventional group(4/7 versus 0/9, p=0.019). Conclusion: Deferoxamine seems to have no clinical benefit compared with the conventional treatment.

  • Objectives : The Knee degenerative osteoarthritis patients are not satisfied with the conventional therapies of KDOA, which results in the use of alternative therapies. The miniscalpel acupuncture is effective in treating chronic soft tissue, releasing contractures. However, there is little scientific evidence supporting the use of miniscalpel acupuncture in knee degenerative osteoarthritis. This study was designed to obtain basic data for a further large-scale trial as well as provide information about the feasibility of miniscalpel acupuncture in knee degenerative osteoarthritis patients. Methods : We describe the protocol for a randomized controlled pilot clinical trial of 5 weeks duration. Twenty patients will be recruited and randomly allocated to two treatment groups: miniscalpel acupuncture treatment(experimental group); and acupuncture and electro-acupuncture treatment(control group). Miniscalpel acupuncture will be performed once with a 1-week interval for 3 weeks. Electro-acupuncture will be administered twice per week for a period of 3 weeks. The primary outcomes will be measured by visual analogue scale and range of motion. The secondary outcomes will be short-form McGill Pain Questionnaire and Western Ontario and McMaster Universities Osteoarthritis Index. Both primary and secondary outcomes will be measured at baseline and at 1, 2, 3 and 5 weeks(i.e. 2 weeks after treatment completion). Conclusions : This pilot study will provide a basic foundation for a future large-scale trial as well as information about the feasibility of miniscalpel acupuncture in knee degenerative osteoarthritis.
