Better timing of ultrasound-guided transversus abdominis plane block for early recovery after open inguinal herniorrhaphy: A prospective randomised controlled study.

Background: This study investigated the optimal timing of analgesic transversus abdominis plane (TAP) block in the operating room for better recovery quality using the Korean version of the Quality of Recovery-40 (QoR-40K) questionnaire in patients who had undergone open inguinal herniorrhaphy.

Methods: This single-centre, prospective randomised controlled study included adult male patients who had an ASA physical status of I-II. A total of 80 patients were analysed.

Prevalence and phylogenetic analysis of the isolated type I porcine reproductive and respiratory syndrome virus from 2007 to 2008 in Korea.

The first Korean strain of porcine reproductive and respiratory syndrome virus (PRRSV) was isolated in 1997, and it exhibited high similarity to strain VR-2332 (type II PRRSV; North American type). Recently, however, infection with type I PRRSV (European type) has also been reported in Korea. To date, preliminary data about type I PRRSV prevalence in Korea have not been reported.

Protective efficacy and immunogenicity of an inactivated avian-origin H3N2 canine influenza vaccine in dogs challenged with the virulent virus.

Transmission of avian-origin influenza A virus (H3N2) to dogs had been reported and since then the H3N2 virus infection across South Korea has been occurred repeatedly in the country's animal clinics and kennels. Dog-to-dog transmission of the virus had also been experimentally demonstrated by direct contact. In this study, immunogenicity and protective efficacy against challenge exposure of the formalin-inactivated H3N2 influenza virus vaccine with a synthetic polymer adjuvant was investigated in dogs.

A serological survey of avian origin canine H3N2 influenza virus in dogs in Korea.

Canine H3N2 influenza viruses of avian origin were recently isolated and found to induce disease in dogs. Results of serologic analysis indicate that avian origin canine influenza virus can spread rapidly through local dog populations, which indicates its potential for becoming established in dogs throughout Korea.

Experimental infection of dogs with avian-origin canine influenza A virus (H3N2).

Susceptible dogs were brought into contact with dogs experimentally infected with an avian-origin influenza A virus (H3N2) that had been isolated from a pet dog with severe respiratory syndrome. All the experimentally infected and contact-exposed dogs showed elevated rectal temperatures, virus shedding, seroconversion, and severe necrotizing tracheobronchitis and bronchioalveolitis.

Transmission of avian influenza virus (H3N2) to dogs.

In South Korea, where avian influenza virus subtypes H3N2, H5N1, H6N1, and H9N2 circulate or have been detected, 3 genetically similar canine influenza virus (H3N2) strains of avian origin (A/canine/Korea/01/2007, A/canine/Korea/02/2007, and A/canine/Korea/03/2007) were isolated from dogs exhibiting severe respiratory disease. To determine whether the novel canine influenza virus of avian origin was transmitted among dogs, we experimentally infected beagles with this influenza virus (H3N2) isolate. The beagles shed virus through nasal excretion, seroconverted, and became ill with severe necrotizing tracheobronchitis and bronchioalveolitis with accompanying clinical signs (e.

Prevalence and genetic characterization of canine parvoviruses in Korea.

The prevalence of canine parvovirus (CPV) variants in dog was investigated in a total of 51 fecal samples submitted over a 2-year period (2005-2007) in Korea. The CPV VP2 gene was amplified and sequenced from the fecal samples, and the results indicated that of the 51 samples, 49 samples belong to the CPV-2a family, 1 to CPV-2b, and the remaining 1 to CPV-2a variant. The VP2 gene of 20 isolates was sequenced and phylogenetic analysis was conducted.

Cloning and further sequence analysis of the ORF3 gene of wild- and attenuated-type porcine epidemic diarrhea viruses.

The open reading frame (ORF3) genes of the parent DR13, attenuated DR13, KPED-9, P-5V, and 12 field samples were cloned and sequenced to further explore the functions of wild- and attenuated-type porcine epidemic diarrhea viruses (PEDVs). Sequencing revealed that wild-type PEDVs ORF3 genes had a single ORF of 675 nucleotides encoding a protein of 224 amino acids with a predicted M (r) of 25.1-25.

Impact of porcine group A rotavirus co-infection on porcine epidemic diarrhea virus pathogenicity in piglets.

Porcine epidemic diarrhea virus (PEDV) and porcine group A rotavirus (PGAR) are the main causative agents of acute diarrhea in piglets. In South Korea, PGAR is prevalent in piglets naturally infected with PEDV. Piglets naturally co-infected with PEDV and PGAR appeared to have severe and prolonged diarrhea that was distinct from that commonly observed.

Evaluation of a rapid immunodiagnostic test kit for rabies virus.

A rapid immunodiagnostic test kit for rabies virus detection was evaluated using 51 clinical samples and 4 isolates of rabies virus. The quick detection of rabies virus under field conditions may be helpful in determining if post-exposure prophylaxis is needed, thereby avoiding unnecessary treatments, as well as undue economic burden. There are several widely used diagnostic methods for rabies, including fluorescent antibody tests, reverse transcription polymerase chain reaction, and electron microscopy; however, these methods include time-consuming, intricate, and costly procedures.

Effects of epidermal growth factor on atrophic enteritis in piglets induced by experimental porcine epidemic diarrhoea virus.

Epidermal growth factor (EGF) promotes gastrointestinal mucosal recovery by stimulating the mitogenic activity of intestinal crypt epithelial cells. The aim of this study was to determine the effects of EGF on atrophic enteritis induced in piglets by experimental infection with porcine epidemic diarrhoea virus (PEDV) strain Dr13. Two groups of 12 conventional, colostrum-deprived, 1-day-old, large White-Duroc cross breed piglets were inoculated orally with PEDV (3 x 10(5) 50% tissue culture infective doses), with or without EGF (10 microg/kg/day, intraperitoneally once daily for 4 days after infection) and compared to 12 uninfected, untreated control piglets.

Sequence analysis of the partial spike glycoprotein gene of porcine epidemic diarrhea viruses isolated in Korea.

Porcine epidemic diarrhea virus (PEDV) causes a devastating enteric disease with acute diarrhea, dehydration and significant mortality in swine, thereby incurring heavy economic losses in Korea. Spike (S) glycoprotein has been suggested as an important determinant for PEDV biological properties. In this study, the nucleotide and deduced amino acid sequences of the partial S glycoprotein genes of Korean PEDV isolates, including epitope region that is capable of inducing PEDV-neutralizing antibodies, were determined.

Multiplex PCR for the simultaneous detection of pseudorabies virus, porcine cytomegalovirus, and porcine circovirus in pigs.

The use of porcine organs is being developed as a means to alleviate the shortage of human organs for transplantation. Recommendations have been published for the microbiological specifications of organ-source pigs to reduce the possibility of a microorganism from pigs being inadvertently transferred to the recipient of the xenograft. The pseudorabies virus (PRV), porcine cytomegalovirus (PCMV), and porcine circovirus (PCV) are infectious agents in pigs that are considered to be of significance for the microbiological safety of xenotransplantation.
