Multiple species of muridae and arvicolidae rodents serve as the natural reserviors of hantaviruses. Hantaviruses are distributed in rodent populations world-widely even in geographical areas where hemorrhagic fever with renal syndrome (HFRS) has not been reported. Serologic diagnosis of infection, using hantaviral antigen, indicates that hantaviruses are wider distributed in wild rodents. This study was designed to intended the hantavirus infection among wild rodents captured in Kyebang mountain, Kangwon-do in Korea. A total of 216 wild rodents in 3 species were trapped in July and September in 1995. Serological evidence for hantaviruses infection were tested against five hantavirus antigens by indirect immunofluorescent antibody technique (IFA). Among 100 Eothenomys regulus, 78 Apodemus peninsulae and 38 Apodemus agrarius (IFA). Among 100 Eothenomys regulus, 78 Apodemus peninsulae and 38 Apodemus agrarius; 12 C. regulus, 15 A. peninsulae and 6 A. agrarius were IF antibody positive against hantaviruses. This data suggest that Eothnomys regulus and Apodemus peninsulae would be a natural reservoir of hantaviruses.

BACKGROUND: Sustained-release theophylline, which is generally prescribed as a twice-daily equal-dose regimen, is one of the more common asthma treatments. the development of a sustained-release drug delivery technology that enables improved control of the theophylline blood levels represents a significant advancement in both the efficacy and safety of dosing. METHOD: A crossover study was conducted with 25 adult chronic asthmatic patients requiring daily bronchodilator therapy. The study group included thirteen males and twelve females with ages ranging from 19 to 71 years. The overall approach was to place the patients first on the twice-daily preparation(Etheophyl®) for 28 days at 8 AM and 8 PM, and measure the pulmonary function and theophylline level on the 28th day. the patients were subsequently switched to the once-daily preparation(Uniphyl®) in the same daily dose at 8 PM on the 29th day and the same parameters were measured on the 56th day. RESULTS: the mean serum levels of theophylline were 8.18±1.66µg/ml in the Etheophyl®-treated period and 8.00±1.75µg/ml in the Uniphyl®-treated period. In addition, the FEV1 showed 71.40±7.48 percent in the Etheophyl®-treated and 69.18±9.00 percent in the Uniphyl®-treated period. Thus there were no significant differences between the once-daily and twice-daily preparation. CONCLUSION: The results indicated little clinical differences between the two medication. The two drugs are equally effective in controlling asthma over the four weeks of treatment.

Objective To compare clinical features,pulmonary functions,chest imaging and prognosis between combined pulmonary fibrosis and emphysema syndrome (CPFE) and idiopathic pulmonary fibrosis(IPF) without emphysematous changes in elderly patients.Methods 88 elderly IPF patients in Beijing hospital from January 2000 to October 2012 were divided into CPFE (n=30) and IPF (n =58) groups according to the CT imaging.Clinical features,blood gas analysis,pulmonary function,chest CT and survival time were compared between the two groups.Results 30 CPFE patients with the mean age of(75.5 ±7.6) years and 58 IPF patients without emphysema with the mean age of(73.7±6.8) years were enrolled.The proportions of male patients,smoking history and mortality were higher in CPFE patients than in IPF group(86.7% vs.63.8%,28 vs.36,76.7% vs.43.1%,x2 =5.09,9.74,8.98,P<0.05 or 0.01).CPFE patients had a higher force vital capacity(FVC) and total lung capacity(TLC) as compared with IPF group [(2.6±0.9) L vs.(2.1± 0.5) L,(5.4±1.9) L vs.(4.4±1.1) L,t=2.69,2.35,P<0.01 or 0.05].There were no significant differences in forced expiratory volume in one second(FEV1) and the diffusion capacity for carbon monoxide(DLCO) between the two groups.The main type of emphysema by HRCT scan were centrilobular emphysema in CPFE patients.There were lower median survival time in CPFE group than in IPF group [(3.0±0.2) years vs.(4.0±1.0) years,x2=4.50,P<0.05].Conclusions The majority of elderly CPFE patients are males and smokers.The lung volume is increased in elderly CPFE patients as compared with IPF patients.Centrilobular emphysema is the primary type in CPFE patients.The prognosis is worse in elderly CPFE patients than in IPF patients.

OBJECTIVETo investigate the expression of zinc finger E-box binding homebox 1 (ZEB1) in the prepuce of hypospadias children and its relationship to the incidence of hypospadias.
METHODSPrepuce tissues were collected from 37 children aged 6-15 months undergoing hypospadias repair and 11 age-matched controls receiving circumcision. Based on the position of the urethral meatus, the hypospadias cases were classified as severe (n = 13) and mild-moderate (n = 24). The mRNA and protein expressions of ZEB1 were determined by immunohistochemistry and RT-PCR.
RESULTSThe expression of the ZEB1 protein was remarkably higher in the severe (100% [13/13]) and mild-moderate hypospadias patients (75.0% [18/24]) than in the controls (9.1% [1/11]), with statistically significant differences between any two groups (P < 0.05). RT-PCR showed the integrated density value (IDV) of the ZEB1 mRNA expression to be (0.67 ± 0.21), (0.81 ± 0.24), and (1.55 ± 0.29) in the control, mild-moderate, and severe hypospadias patients, respectively, significantly higher in the severe hypospadias than in the control and mild-moderate hypospadias groups (P < 0.05), but with no significant difference between the latter two (P = 0.64).
CONCLUSIONThe expression of ZEB1 is significantly increased in hypospadias patients, and its upregulation is positively correlated with the severity of hypospadias, which suggests that the overexpression of ZEB1 may contribute to the development of hypospadias.

A case of unilateral multicystic renal dysplasia was reported in view of rarity, and a review of literature 23-year-old female was admitted to Kyung Hee University Hospital with a complaint of urinary incontinence. An excretory urogram revealed non-visualization of the right kidney. The right ureter had opening at the 2 cm above the vaginal introitus. The resected right kidney revelaed multilobulated outer surface with multiloculated cystic struture on cut surface. The associated anomaly was uterine didelphy. The condition was treated by nephroureterectomy.

Anal incontinence following pelvic trauma, surgery, or neurologic disorders has significant medical and social implication. Both Chetwood in 1902 and Bistom in 1944 utilized coccygeal origin portion of the gluteus maximus muscle for the anal sphincter reconstruction. The gluteus maximus muscle is a broad, fan-shaped muscle with a wide origin from the ilium sacrum and coccyx and a narrow insertion along the iliotibial band of the lateral femur. Its blood supply is from the inferior gluteal artery and its innervation is from L-5, S-1 roots by means of the inferior gluteal nerve Incisions are placed at the inferior border of the ischial tuberosity. Subcutaneous tunnels are created about the rectum and gluteal and perirectal incisions. Two overacting slings are being created Their opposing pull creates sphincter or valve effect about the distal rectum. We have experienced 2 cases of irregular, deep soft tissue defects of the perianal region requiring muscle coverage with the gluteus maximus muscle overlapping slings. We think the use of the gluteus maximus muscle is one of the most useful method for reconstruction of the anal sphincter mechanism.
