This study was done to evaluate the efficacy of Vapormate (ethyl formate 16.7 % + CO2) as an methyl bromide-alternative fumigant. Some insect pests and mites were found under calyx of sweet persimmon fruits, including grape-myrtle scale, two-spotted spider mite, Amblyseius eharai. Vapormate fumigation was equally toxic to miticide- susceptible and -resistant T. urticae showing 100 % mortality at higher concentration than 146.7 and 211.0 mg/L, respectively. In persimmon-filled desiccator, summer and overwintering types of T. urticae showed 100 % mortality at higher concentration than 163.7 and 265.8 mg/L, respectively. Sweet persimmon damage from vapormate fumigation was not shown by the days after treatment. Tolerance of each live stage of grape-myrtle scale was in descending order: egg < nymph < adult. EF 141.5 mg h L-1 for 6 h at 5 ℃ killed 100 % of the larvae of D. punctiferalis. The final scaled-up fumigation confirmed the efficacy of EF to target pests and non-phytotoxicity on persimmons. In conclusion, EF may become a MB alternative fumigant for sweet persimmon, and the LC99 values of EF may be used to practical applications to all kinds of insects and mites on harvested sweet persimmon.

Retroperitoneal fibrosis (RPF) is a rare disease characterized by the presence of retroperitoneal tissue marked by chronic inflammation and prominent fibrosis. A 67-year-old man presented with general weakness and oliguria. Laboratory findings showed blood urea nitrogen 77.7 mg/dL, serum creatinine 9.24 mg/dL, and an IgG4 level within the normal range. Computed tomography (CT) findings showed bilateral hydronephrosis and distal ureteral obstruction due to fibrotic adhesion to a presacral mass. Laparoscopic biopsy was performed. The authors report a case of acute kidney injury caused by non-IgG4 related focal retroperitoneal fibrosis in the pelvis that was successfully treated using prednisolone and tamoxifen… non-IgG4 related focal retroperitoneal fibrosis caused byacute kidney injury.

Micrococcus lutus is common gram-positive aerobic cocci present in soil, water, dust, and the skin of humans and animals. A 72-year-old man was admitted to the hospital with a complaint of abdominal pain and a turbid peritoneal dialysate. He was empirically treated with intraperitoneal (IP) cefazolin and ceftazidime. Seven day after admission, Gaffkya species was identified from the peritoneal effluent. He was treated with same organism one month ago and discharged with the dialysis catheter intact. So, we suspected that organism is true pathogen, and identified M. luteus by culture. We changed the antibiotics to cefoxitin, which were given for the total of 14 days. This is the first report of relapsing peritonitis by M. luteus and successful treatment without catheter removal.

Peritonitis is a common, major complication in continuous ambulatory peritoneal dialysis (CAPD) patients and tuberculous (TB) peritonitis has been reported to constitute 1-2% of all peritonitis cases. In CAPD patients, TB peritonitis is often diagnosed late and has a high mortality rate. In a recent recommendation made regarding the treatment of TB peritonitis, primary removal of a peritoneal dialysis catheter has been advised in addition to anti-TB drugs. Here, we describe two cases of TB peritonitis in CAPD patients successfully treated without peritoneal dialysis catheter removal.

Italian Ryegrass is a high productivity and feed value, and an upright grass that behaves like a biennial or short-lived perennial. It grows vigorously in winter and early spring. Italian ryegrass and a related species, perennial ryegrass, Lolium perenne, are the two common weedy ryegrassses. Italian ryegrass and perennial ryegrass can hybridize, resulting in offspring that are difficult to identify as either species. Ryegrasses are cultivated for turf and forage. Sometimes Italian ryegrass is grown as cover crop. It has the potential to produce high yields and, with proper management, can be high quality with good animal performance. To develop of a high quality, productivity and early variety, 20 varieties examined growth and yield characteristics. The heading date of Green farm with high cold tolerance was on 28 April. Most of Introduced varieties except Grazer have mid and late heading date.

“Onnuri” is a new orchardgrass(Dactylis glomerata L.) variety developed by the National Institue of Animal Science (NIAS) in 2011. To develope the new variety of orchardgrass, 5 superior clones were selected and polycrossed for seed production. Agronomic growth characteristics and forage production of “Onnuri” were examined at Cheonan from 2009 to 2011, and regional trials were conducted in Cheonan, Pyungchang Jinzu and Jeju from 2009 to 2011, respectively. “Onnuri” showed medium type growth habit in fall and spring and medium in length of flag leaf and long upper internode. Plant height of “Onnuri” was more than 10cm that of standard variety, “Amba” and heading date was 5 days earlyer than 16th May compared to Amba. Characteristics such as waterlogging, disease resistance of “Onnuri” were stronger or better than those of Amba, specially “Onnuri” showed 18% higher dry matter yield (14,775kg/ha) compared to Amaba(12,523kg/ha). Nutritive value was appeared to be similar in both varieties.
