Four strains of fowl adenovirus (FAdV) were isolated from 4 flocks of broiler or layer chickens affected by hydropericardium syndrome in Korea. These FAdVs were classified as serotype 4 by restriction fragment length polymorphism patterns of hexon genes and whole genomes. The virus exhibited cytopathic effects consisting of rounding, ballooning and clustering in primary chicken embryo liver cell cultures. In transmission electron microscopy, virus particles in hexagonal shape aggregated exclusively in the nuclei of hepatocytes of the chickens as the typical appearances in adenovirus infections. Buoyant density of the virus in cesium chloride (CsCl) was 1.34 g/mL. The virus was stable to chloroform, ether, 50~70% ethanol, acidic condition at pH 3, 0.25% trypsin (1 : 250), heat at 50degrees C for 30 min, but labile to 100% ethanol, heat at 52~60degrees C for 30 min, 1 M MgCl2 at 50degrees C for 1 h, 1 : 2,000 formalin (37%). All of the physicochemical properties pertained to the characteristics of adenoviruses. Eight viral polypeptides were determined in CsCl-purified virus by sodium dodecyl sulfate-polyacrylamide gel electrophoresis.

H-reflex is a kind of late respons which can be used for the proximal nerve conduction study. Also it is a useful and widely used nerve conduction technique es to look electrically at the monosynaptic reflex. Although recordable from all muscles theoretically, H-reflexes are most commonly recorded from the calf muscles following stimulation of the tibial nerve in the popliteal fossa. But in this study, We tried to establish the normal data and to evaluate the significance of the H-reflex study in cervical radiculopathy. H-reflexes were recorded from flexor carpi radialis (FCR) muscle, extensor carpi radialis (ECR) muscle, brachioradialis (BR) muscle, and abductor digiti minimi (ADM) muscle in 31 normal adults (62 cases) and 12 patients with cervical radiculopathy. The mean values of H-reflex latency in normal control group were 16.16+/- 1.65 msec in FCR; 15.99+/- 1.25 msec in ECR; 16.47+/- 1.59 msec in BR; 24.46+/- 1.42 msec in ADM. And the mean values of side to side difference of H-reflex latency were 0.47+/- 0.48 msec in FCR; 0.68+/- 0.72 msec in ECR; 0.63+/- 0.43 msec in BR; 22.31+/- 1.24 msec in ADM. Mean values of side to side differences of interlatency time were 0.49+/-0.47 msec in FCR; 0.73+/- 0.62 msec in ECR; 0.79+/- 0.71 msec in BR; 0.69+/- 0.44 msec in ADM. Also, there were no significant differences in H-reflex latency between right and left side. H-reflex tests in patient group with cervical radiculopathy revealed abnormal findings in 11 out of 12 patients. These results suggest that H-reflex in the upper extremity would be helpful in the diagnosis of the cervical radiculopathy.

PURPOSE: The purpose of this study was to evaluate the overall rate and risk factors for the development of an incisional hernia and a parastomal hernia after colorectal surgery. METHODS: The study cohort consisted of 795 consecutive patients who underwent open colorectal surgery between 2005 and 2007 by a single surgeon. A retrospective analysis of prospectively collected data was performed. RESULTS: The overall incidence of incisional hernias was 2% (14/690). This study revealed that the cumulative incidences of incisional hernia were 1% at 12 months and 3% after 36 months. Eighty-six percent of all incisional hernias developed within 3 years after a colectomy. The overall rate of parastomal hernias in patients with a stoma was 6.7% (7/105). The incidence of parastomal hernias was significantly higher in the colostomy group than in the ileostomy group (11.9% vs. 0%; P = 0.007). Obesity, abdominal aortic aneurysm, American Society of Anesthesiologists score, serum albumin level, emergency surgery and postoperative ileus did not influence the incidence of incisional or parastomal hernias. However, the multivariate analysis revealed that female gender and wound infection were significant risk factors for the development of incisional hernias female: P = 0.009, wound infection: P = 0.041). There were no significant factors related to the development of parastomal hernias. CONCLUSION: Our results indicate that most incisional hernias develop within 3 years after a colectomy. Female gender and wound infection were risk factors for the development of an incisional hernia after colorectal surgery. In contrast, no significant factors were found to be associated with the development of a parastomal hernia.

During revascularization after ischemia, oxygen free radicals and cytotoxic enzymes are released and they have a role in pathogenesis of ischemia-reperfusion injury. Glucocorticoid decreases oxygen free radical formation by inhibition of arachidonic acid metabolism, and alpha-lipoic acid scavenges nitric oxide(NO) with inhibition of hydroxy radical formation. Author investigated the role of glucocorticoid and alpha-lipoic acid to decrease ischemia reperfusion injury in 24 anesthetized rats (normal saline-injected, n= 8; dexamethasone-injected, n=8; alpha-lipoic acid-injected, n= 8), subjecting a soleus muscle to 4 hours of tourniquet ischemia followed by 2 hours of reperfusion, and evaluated the concentration of NO, tissue edema, and neutrophil count of rat skeletal muscle as a indicator of tissue damage by ischemia- reperfusion injury. We obtained the results that glucocorticoid and alpha-lipoic acid treatment decreased the increase of NO concentration, tissue edema, and neutrophil count significantly. These results support that pretreatment with glucocorticoid or alpha-lipoic acid has a beneficial effect on the preventive management of ischemia-reperfusion injury.

BACKGROUND: Familial hypercholesterolemia(FH) is an autosomal dominant metabolic disorder caused by the mutation in low density lipoprotein receptor(LDLR) gene. However, direct genetic diagnosis of LDLR gene mutation is not easily available because more than 300 mutations have been described in LDLR gene of FH patients. Therefore indirect genetic diagnosis using the genetic markers can be used to follow the inheritance of defective gene in FH families. The purpose of this study was to evaluate the usefulness of indirect genetic markers for detecting identical-by-descent LDLR gene abnormalities in FH families. METHODS: We examined the allele frequency, heterozygosity, polymorphism information content(PIC) of each genetic markers(D19S394, Taq I, Hinc II, Ava II, ATn, D19S221) in 94 unrelated healthy subjects. The genetic polymorphic haplotypes in 3 FH families were also determined. RESULTS: The heterozygosity and PIC values of RFLP's(Taq I, Hinc II, Ava II) were 0.51/0.344, 0.25/0.223, 0.28/0.233 and microsatellite markers(D19S394, ATn, D19S221) were 0.64/0.558, 0.56/0.455, 0.60/0.475. Hinc II and Ava II were significantly linked(|D|=0.72, p< 0.05). The cumulative PIC values of Taq I+Hinc II, Taq I+Hinc II+ATn, D19S394+ATn were 0.520, 0.814, 0.813, respectively. When applied in the FH pedigree, the genetic diagnosis using only one marker was not available in most cases. However, combination of two or more genetic markers could successfully discriminate the affected and unaffected members in FH families. Among the several combinations of the genetic markers, the combination of D19S394 and ATn was supposed to be the most effective and informative. Because one case of recombination was suspected in D19S221 allele, it was thought to be carefully used for genetic diagnosis of FH. CONCLUSION: We concluded that indirect genetic diagnosis using intragenic or extragenic genetic markers was useful for detecting identical-by-descent LDLR gene abnormalities in FH families and the most effective and informative combination of genetic marker seemed to be D19S394 and ATn.

Bacteriophages were induced from staphylococcus intermedius isolates from dogs and used for a phage typing. Mitomycin C induction was performed on 60 strains of S. intermedius and all phages were reacted with the strains. Twenty-eight strains (46.7%) were found to be lysogenic. Based on host ranges, eight phages were selected. By using the eight phages, 129 strains isolated from canine clinical specimens were subjected to the phage typing at the routine test dilution (RTD) and 100xRTD. Typability of the phage set was 78.3%, yielding 40 phage patterns. The phage set was considered useful for differentiating S. intermedius strains isolated from dogs. None of 50 strains of S. aureus, 2 (3.6%) of 56 S. simulance strains, 13 (24.5%) of 53 S. chromogenes strains and 46 (28.1%) of 164 S. hyicus strains were typable by the phages at 100xRTD.
