This study was conducted to analyze the mixing ratio of raw feed materials for the methane mitigation and also to identify the minimum rearing density for improving the productivity of beef calves as eco-friendly fodder. Raw materials used in this study for the formulation of feed for methane reduction were crushed corn and alfalfa along with other 21 species. In addition, to investigate the appropriate rearing density, 12 Hanwoo calves with average weight of 150 kg was selected and experiment was conducted for four months. Methane gas emission (Bo) is about 3-4 times less in TMR 4 compared to TMR 1, 2 and 3. Feed price calculated for TMR 4 ration was also affordable. In addition, all TMRs showed a normal ruminal pH. Disappearance rate was observed to be lower in TMR 4 as compared to TMR 1, 2 and 3, but methane production decreased by 24 to 37%. The result showed improved total body weight, average daily gain and feed conversion ratio in rearing low-density ($18m^2/head$), and general treatment ($9m^2/head$) compared to overcrowding treatment ($6m^2/head$). In addition, blood components (total protein, glucose, AST, ALT and GGT factors) involved in health and disease treatments and health-related nutrition metabolism are lower in the low-density and general treatment compared to the high density treatment. Postural development (development of body size) i.e., weight, height and width significantly increased in the low and general density treatment compared to high density treatment. Especially excellent improvement was observed in low-density treatment than the general treatment. Moisture content, colonic bacteria and coccidium are higher in low and high density treatments than in the general treatment. The adequacy for beef rearing density is considered to be more desirable in an area more than $6m^2/head$. In conclusion, present study suggests that possibility of methane reduction through adjusting mixed feed ration. Also, rearing density is also an important factor in the growth and development of beef calves.

Purpose : Henoch-$Sch{\ddot{o}}nlein$ purpura nephritis(HSPN) accompanied by nephrotic syndrome(NS) is known to have a poor prognosis and effective treatment is still controversial, even though both corticosteroids and immunosuppresant have been used for therapy. Cyclosporine A(CsA) is a well known immunosuppresant and widely used in renal transplantation and glomerular diseases especially steroid resistant. The aims of this study was to evaluate the therapeutic effect of CsA and to compare CsA with previously reported our data of rifampin(RFP) and azathioprine(AZA) in children with HSPN accompanied by NS. Methods : 37 HSPN patients with NS confirmed by renal biopsy were selected. Of these, 17 patients were treated with CsA(5 mg/kg/day) fur 6-8 months, 7 children were treated with RFP(10-20 mg/kg/day) for 9-12 months and 13 patients were treated with AZA(2 mg/kg/day) fur 8 months. Along with these regimens, low dose oral prednisolone(0.5-1 mg/kg, qod) was also used. Sequential renal biopsy was done in all patients 1 month after termination of treatment. Results : Complete remission rate of nephrotic syndrome was $58.8\%$ in CsA, $57.1\%$ in RFP and $38.4\%$ in AZA group after 17, 22, 11 months of mean follow-up period. Overall remission rate including partial remission was $88.2\%$ in CsA, $85.7\%$ in RFP and $84.6\%$ in AZA group. Disappearance rate of hematuria was $58.8\%$ in CsA, $57.1\%$ in RFP and $46.2\%$ in AZA group. Improvement of grade of clinical status was observed in 17 out of 17 CsA, 7 out of 7 RFP and 10 out of 13 AZA group. Improvement of pathologic class on sequencial renal biopsy was shown in 5 CsA($29.4\%$), none RFP($0\%$) and 2 AZA group($12.4\%$). Improvement on histologic immune-deposition was seen in 15 CsA($88.2\%$), 6 RFP($85.9\%$) and 4 AZA group($30.8\%$). Conclusion : In conclusion, Both CsA and RFP treated groups showed better result in complete remission rate of nephrotic syndrome and significant improvement of histologic immune-deposition compared with AZA treated group(p=0.004). So, we recommend CsA and REP rather than AZA for immunosuppresant treatment in HSPN with nephrotic syndrome.
Purpose : There is no specific treatment guidelines for Henoch-$Sch{\ddot{o}}nlein$(HS) nephritis. Therefore we performed this study to observe the effect of long term steroid therapy combined with azathioprine Methods : Treatment protocols; 1) Steroid pulse therapy: methylprednisolon 30 mg/kg/dose, maximum 1 gm, intravenolisly 6 times for alternate day. 2) Oral steroid was given 2 mg/kg/day for 1 month, 1 mg/kg/day for following 1 month and alternate day oral steroid combined with azathioprine 2 mg/kg/day for 2 years. Results : Time period from HSP to onset of HS nephritis was between 2 weeks to 5 months with mean $7.4{\pm}7.4$ weeks. Clinical remission were seen in 4 cases out of 5 ($80\%$). Mean time period with disappearance of proteinuria and microscopic hematuria were $5{\pm}2.4$ month and $13.3{\pm}2.9$ month respectively. On pathologic findings by ISKDC, 3 cases were grade IIIb, 2 cases were grade IV in first kidney biopsies and showed pathologic improvement in follow up tidneybiopsiesafterlyearstreatment. Conclusion : As there is no definitive treatment for HS nephritis so far, our study of long term oral steroid therapy with azathioprine was effective in clinical and histologic aspect. Therefore further study in HS nephritis with in a large group will be needed in the future.
Prosthetic valve thrombosis(PVT) may be a life-threatening complication requiring prompt intervention. This is a case report of thrombolytic therapy for thrombosis of prosthetic mitral valve. A 47 year-old male admitted to the emergency room for abrupt onset of dyspnea. He had undergone mitral valve replacement(On-Ⅹ valve, 29mm) for mitral stenosis 8 months ago. The patient's international normalized ratio(INR) on admission was 1.09. The mechanical clicks were muffled and rales were heard in both lung fields. A transesophageal echocardiography(TEE) revealed prosthetic valve thrombosis with increased transvalvular pressure gradient(34 mmHg). The patient's condition needed to intubation for mechanical ventilation due to hemodynamic compromise, however his wife and relatives refused the surgical intervention due to financial problems. The patient was transferred to the cardiac care unit and we decided to perform thrombolytic therapy. A bolus of 1,500,000 IU of urokinase was given, followed by a drip of 1,500,000 IU for 1 hour. The patient did not improved hemodynamically; therefore, we gave 100 mg of tissue plasminogen activator(t-PA) for over 2 hours. During that time mechanical clicks were audible and hemodynamics of the patient improved progressively. A TEE showed disappearance of thrombus and decreased pressure gradient(1.7 mmHg) after 6 hours of thrombolytic therapy. The patient was recovered without any neurologic sequale and was discharged with administration of warfarin.

Purpose : $Henoch-Sch{\ddot{o}}nlein$ purpura(HSP) is a systemic vasculitis involving small vessels of skin, gastrointestinal(GI) tract and kidney. Digestive involvement of HSP can be serious with massive GI bleeding, perforation, and intussusception. However, some patients do not respond to conventional corticosteroid therapy. In this study, we investigated the efficacy of intravenous immunoglobulin (IVIG) for serious digestive manifestations not responding to steroid. Methods : From April 1999 to January 2005, 22 children diagnosed as HSP with severe GI symptoms were included. Initially, all patients were treated with intravenous methylprednisolone. IVIG 2 g/kg of body weight was infused in children refractory to steroid therapy. Clinical data were reviewed retrospectively. Results : Among 22 children, 12 children underwent IVIG therapy. The mean duration of corticosteroid therapy was $5.61{\pm}4.9$ days before IVIG therapy, and 11 of 12 patients experienced disappearance of GI manifestations after the initiation of IVIG infusion. In one patient, IVIG was ineffective in relieving abdominal pain, but melena subsided. Comparison of the duration of hospitalization between IVIG group and corticosteroid group revealed no significant difference($12.8{\pm}7.6$ days vs. $13.2{\pm}7.8$ days, P=0.777). But, the total duration of abdominal pain decreased in IVIG group although the difference between two groups was not significant($8.8{\pm}8.1$ days vs. $14.8{\pm}16.9$ days, P=0.306). Among 10 children treated with steroid only, 2 children were operated for bowel perforation and intussusception. In contrast, there was no perforation in 12 children who underwent IVIG therapy. Conclusion : IVIG could be the alternative therapy to corticosteroids in children with severe digestive manifestations of HSP.

This study aimed to reveal the establishment process and spatial composition of TaiSho park in modern Busan. The TaiSho park is an athletic park which combines a playground and a rest facilities. The arguments on construction of playground commenced for commemorating Kameyama, Busan director official, when he moved to Taiwan in 1910. First Proposers which construct to sport park were businessman in that time. However, construction of playground was progress as a commemoration business of accession of Taisho Tenno. Playground construction got into stride by the proposal of the Busan mayor Wakamatsu in 1917. When it looks into process of discussion about a site selection candidate, norms of playground site selection are the paly ground which appropriate with effective site area and distance between park and a section of a city, in other hand, those are accessibility and budget. As a result of several arguments and actual site investigation, it was decide to select a site which enters to elementary school, after the isolation hospital relocates. The cost of construction of the TaiSho park is prepared by donation of the Busan civil. The donation fund raising committee was constituted by local commerce and industry people, a company, government, municipal offices and area, and funds was raised systematically. As a result, total amount of construction cost was made from the donation of local civil. The TaiSho park is broadly into two sectors; exercise area and rest and pleasure space. Entrance was set up in three aspects of the park and the subcontract planted. The baseball field took the seat in the central part of the park, and also prepared two tennis courts. Japanese Sumo field was also prepared for the north side of the park. The significance of the TaiSho park in Korea Park history can be summarized in South Korea's first sports park and which was made from the donation of local civil. The remained subjects from this study are to clarify the disappearance process of TaiSho park and a reason why modern Busan people want to get playground.
These study were conducted to determine the effects of a whole or steam-flaked corn based diet on rumen microbial fermentation in vitro and ruminal metabolism in the Korean Native Goat(KNG) in vivo. The experiments consisted of two dietary treatments: control, steam-flaked corn(SFC) based diet(80%) + rice straw mixed(20%)(SFCR); 100% whole corn based diet(WC). The first experiment was conducted to investigate the effect of whole corn on ruminal metabolism in vitro for 0 to 48 h. pH values were optimally maintained during incubation time, and were not significantly different between treatments. Gas production of SFCR was significantly higher than WC(p<0.01). $NH_3$-N concentration tended to increase for WC, but not significantly different between treatments. The mean value of total volatile fatty acid concentration of WC was significantly lower than SFCR(p<0.01), but SFCR and WC linearly increased as the time of incubation approached 48 h. Mean value of acetate concentration of SFCR was significantly higher than WC(p<0.01). Propionate concentration of WC for the total incubation time was significantly higher than SFCR(p<0.01). The digestibility of dry matter was not significantly different between treatments, but SFCR was somewhat higher than WC. The second experiment was conducted to effect of whole shelled corn based diet on rumen metabolism in KNG. pH values tended to decrease through all treatments. There was not a significantly difference between treatments. Microbial protein yield of SFCR was significantly higher than WC(p<0.01). $NH_3$-N concentration of WC was significantly (p<0.01) higher than SFCR. Total VFA and propionate concentration of WC was significantly higher than SFCR(p<0.01), but acetate concentrate of WC was not significantly higher than SFCR. The mean value of total lactate concentration was significantly(p<0.01) different but the value of SFCR and WC were lower than the average concentration of acidosis. In sacco DM disappearance rate of SFC was significantly(p<0.01) higher than WC.
Purpose : The outbreaks of measles in infants and school children have been reported recently, but there are no specific treatment of these patients except symptomatic therapy. This study was performed to evaluate the effectiveness of intravenous gammaglobulin(IVGG) therapy in acute febrile phase of measles. Methods : The 68 cases in measles were treated with single dose of IVGG(400~500 mg/kg), and 44 cases were treated with only symptomatic treatment during the periods of 14 months from Jan. 2000 to Feb. 2001. They were compared to duration of fever, rash, the levels of CRP and days of admission on both groups after treatment. Results : The results obtained follows. The average of age was $7.9{\pm}3.6$ year old, and male to female was 1.0 : 1.6. The duration of fever after admission was $2.4{\pm}1.2$ days in treated group and $5.7{\pm}2.4$ days in control group. The period of disappearance of systemic erythematous maculopapular rash was $4.5{\pm}1.3$ days in treated group, and $6.9{\pm}2.4$ days in control group. The durations of admission day were also shown significantly shorter duration of period in treated group(P<0.05). The levels of CRP were no significant difference between two groups before treatment. However, treated group was significantly shown by improved within 5 days after IVGG therapy(P<0.05). Conclusions : The single dose of IVGG(400~500 mg/kg) therapy is one of rapid and effective therapy for clinical symptoms and signs in acute high febrile phase of measles.
This study was conducted to determine effects of supplementation levels of aqueous direct-fed microbials (DFM; Bacillus spp.) to TMR(exp. 1.) and aqueous DFM addition under the various ratios of starch and cellulose(exp. 2.) on ruminal fermentation and fibrolytic enzyme activity. In experiment 1, ruminal fluids taken from rumen-cannulated Holstein cows were incubated during 24 hr by using TMR as substrates. Aqueous DFM was applied at a rate of 0, 0.025 and 0.05%, respectively. The pH of 0.025% treatment was not significantly different from that of control at 6 and 9 hr, but it was significantly lower (P<0.05) than 0.05% treatment. Concentrations of ammonia-N and VFAs were not affected by supplementing aqueous DFM. The A:P ratio of 0.05% treatment was significantly increased(P<0.05) by supplementation of aqueous DFM as compared with that of control at 24 hr. Although overall fibrolytic enzyme activities were not significantly affected by supplementing aqueous DFM, CMCase(carboxymethylcellulase) activity showed significant increase(P<0.05) compared to control at 6hr. However, the xylanase activity of 0.05% treatment significantly decreased(P<0.05) at 12 hr due to the application of aqueous DFM. There was no significant difference for in vitro dry matter disappearance among treatments. In experiment 2, ruminal fluids were incubated under the condition of various ratios of starch to cellulose(90:10, 70:30, 50:50, 30:70 and 10:90) with or without aqueous DFM(0.025%). Ruminal pH was unaffected by the addition of aqueous DFM, however, as increased level of starch, ruminal pH partially showed significant decrease(P<0.05). Ammonia-N concentration was not affected by aqueous DFM and ratio of starch and cellulose. On 9 hr incubation, DFM addition at a ratio of 70:30 showed significantly (P<0.05) lower value of ammonia-N(35.65 mg/dL) than that(65.05 mg/dL) of control. Concentrations of VFAs were significantly increased(P<0.05) by aqueous DFM addition compared with control at the same ratio on 6 hr incubation. The overall CMCase activity was not affected by aqueous DFM addition. However, the xylanase activity by aqueous DFM partially showed significant differences at the ratios of 90:10, 30:70 and 10:90. Our results indicated that supplementation of aqueous DFM did not significantly improve in vitro fermentation and fibrolytic enzyme activity. In addition, the DFM utilized in this study did not show consistent results by having various effects on ruminal fermentation under different feeding regimens.

When mammalian oocytes ovulate into the oviduct, associating follicular fluid components are exposed to the oviductal environment, possibly resulting in the mutual interaction between fillicu1ar and oviductal fluids. In the Present study, we have demonstrated for the first time that components of fallicular fluid could be modified by the oviductal fluid. Gelatin zymographic analyses of human follicular fluid (hFF) obtained from IVF patients showed consistently the presence of 110 kDa gelatinase (GA110) in addition to many bands among which 62 kDa gelatinase was predominant. Addition of EDTA or phenanfhroline to the gelatinase substrate buffer during gel incubation abolished GA110 band whereas phenylmethylsulffnyl fluoride (PMSF) did not. In contrast, bovine oviductal fluid(bOF) exhibited only 62 kDa gelatinase. Surprisingly, when bOF was added to hFF in 1:1 ratio and then the mixture was incubated for 3 h at 37$^{\circ}$C, GA110 of hFF disappeared. Disappearance of GA110 by bOF was observed even within 30 min after mixing with hFF. Addition of aminophenylmercuric acetate (APMA) to hFF also abolished enzymatic activity of GA110 but increased the activityof 62 kDa gelatinase. However, APMA abolished many other gelatinases as well unlike bOF. Interestingly, treatment of hFF with EDTA for 3 h remarkably increased the enzymatic activity of GA110 but not that of other gelatinases. Addition of phenanthroline, PMSF or soybean trypsin inhibitor (SBTI) did not affect overall gelatinase activities. Again, addition of bOF to the hFF pretreated with any of the above proteinase inhibitors abolished the appearance of GA110. Human serum also showed GAI 10 of which activity was greatlyenhanced by EDTA treatment. Similar to hFF, serum GA110 also disappeared by the addition of bOF. Human granulosa cell homogenate did not reveal any appreciable gelatinase activity except 92 kDa gelatinase. Anti-human gelatinase A antibody reacted with 62 kDa gelatinase of hFF. Based upon these results, it is concluded that bOF could selectively degrade an isoform of gelatinase A present in hFF and human serum.
