1.Prevalence of Theileria sergenti infection in Korean native cattle by polymerase chain reaction.
The Korean Journal of Parasitology 2003;41(3):141-145
This study was performed to investigate the prevalence of theileriosis and to compare the prevalence of this disease in Korean native cattle reared under different environmental conditions, namely, in a grazing area and a non-grazing area by polymerase chain reaction. Three hundred and one Korean native cattle (276 cows and 25 bulls) that had not received prior treatment or been vaccinated to prevent theileriosis were examined by PCR for Theileria sergenti infection from 2001 to 2002. In our study, the parasitemia range in T. sergenti-positive cattle by microscopy were from 0.1 to 3% (mean 0.8%). In terms of mean prevalence, 204 of the 301 Korean native cattle (67.8%) were positive reaction by PCR. Our results also revealed that the infection rate among cows (70.3%) was significantly higher than that among bulls (40.0%) (p < 0.01). T. sergenti infection among the over 3 year-old-group (75%) had a significant higher prevalence than that among the less than 3 year-old-group (61.8%) (p < 0.05). Our data also showed that grazing areas (76.1%) had the significant higher prevalence than non-grazing areas (51%) (p < 0.001). In conclusion, this study demonstrates that the prevalence of T. sergenti infection is high and that its prevalence in grazing cattle is higher than that in non-grazing cattle. Therefore, life-long treatment and the development of an optimal vaccine are needed to reduce the numbers of bovine theileriosis in both grazing and non-grazing areas.

Among the many causes producing lower back pain herniated nucleus pulposus and bulging disk have occupiedlarge percentaages and uniformly showed defect on lateral aspect of contrast filled thecal sac. But it isessential to differentiate each conditions from the other because of their different treatment methods.differentiation at metrizamide myelography between a diffusely bullging disk(unlikely to cause nerve rootcompression) and a herniated disk is based on the curature, extent, and multipllicity of the extradural deformityof the anterolateral margin of the contrast filled sac and o hte presence of fusiform widening of the most distalpart of the affected nerve root. The deformities caused by a bullging disk are round, usually symmetrical(aothoughoccasionally more prominent on one side), do not extend above or below the disk space, and can show multiple levelinvolvement; the nerve root is uniform in caliber and normal in size(although some of severe bulging show fusiformwidening of the most distal part of the affected nerve root). The deformities caused by a herniated disk isangular and extends cephalad and/or caudal to the level of the disk space; the affected nerve root is usuallywidened in its most distal visible part. A consecutive series of 50 patients with low back pain and no pasthistory of back surgery who did metrizamide myelography underwent spine CT and /or laminectomy. Using the criterialisted above for differentiation of bulging from herniated disk on metrizamide myelography, the myelographicdiagnosis was correct in 32(22 patients) of 34(24 patients) (95%) surgically and/or computed tomographicallyconfirmed bulging disks and in all 26 (100%) surgically and/or computed tomographically confirmed herniated disks.

Sonographic measurements often give considerable diagnostic significance. However, large discrepancy betweenthe real anatomic sizes and sonographic measurements could cause an incorrect diagnosis. Authors carried out aseries of experiment using a phantom and two scanners and the results are as follows: 1. There is a littledifference in errors between two scanners, and the mesurement does not almost always correspond to the realdistance. 2. The rates of errors of the measurements are almost fixed regardless of the positions of thereflcetors. 3. There is no relationship between the transducer MHZ and error rate. 4. As the error is derived from the scanner electronics it is necessary to calibrate the scanner periodically, and if not calibrated one shouldconsider the error rate of the scanner in the anatomical measurement.

The fibrous dysplasia, divided into 3 categories of the monostotic, polyostotic and extraskeletal forms, is a relatively rare disease which was first reported by Well in 1922 and shows a characteristic findings replacing the medullary cavity of noe or more bones by the pathologically proliferating fibrous connective tissues. In a consequence, the structural integrity of the diseased bone becomes weakened and suffers frequent episodes of pathologic fracture and deformities of the bone, which are most common around the hip. Various operative methods and instruments have been tried to manage the pathologic fracture around the hip recently. The authors report a satisfactory resnlt of total hip replacement for the pathologic fracture in a patient of the fibrous dysplasia involving the proximal half of the right femur.

This study was performed to investigate whethere there is cross-reactivity between Dirofilaria immitis and three intestinal nematodes of dogs. In ELISA, D. immitis-infected dog sera obtained at the 4th molting stage (9-11 weeks) and microfilaremic stage (25-30 weeks) were shown to be highly reactive with crude extract of T. canis. In immunoblotting, some antigenic fractions, 44, 57, 88, 100 kDa of crude extract of T. canis, were found to be positive reaction with sera of dogs infected with D. immitis. However, little or no cross-reaction were observed between sera of D. immitis-infected dogs and crude extract antigen of T. vulpis or A. caninum. These result suggest that there are partial cross reaction between sera of D. immitis-infected dogs and the antigen of T. canis.

The utility of computed axial tomography(CAT) in the diagnosis of spinal disorders has been the subject of considerable interest since the introduction of CAT scanning. Computed tomographic guided needle biopsy of 12 consecutive patients with a variety of undermined spinal disorders resulted in a 100% yield of positive tissue diagnoses, without signlficant complications. The principal advantage of cat guidance is the continuous direct observation of the needle tip position in relation to the target volume. We think that the application of computed tomographic guided needle biopsy in the lesions of the spine is of great value, because it is the single most accurate method of obtaining diagnosis other than by open surgical biopsy.

Journal of the Korean Radiological Society 1995;32(1):169-172
PURPOSE: We evaluated both the patients and the normal volunteers to determine the diagnostic criteria of subacromial impingement syndrome. MATERIALS AND METHODS: We analyzed the radiologic finding of Thirty degree of caudal tilt view (TCTV) and Supraspinatus outlet view (SOV) of 100 shoulders from 85 patients with clinically proved subacromial impingement syndrome and normal 100 shoulders from 60 volunteers. RESULT: In TCTV, the protrusion of acromion below the line of extension from inferior surface of clavicle was shown in 94% of the patient group and 48% in normal group. Sharp tip of acromial protrusion was detectable in 55.3% of the patient group and 10.4% in normal group. In SOV, curved type of acromion was seen in 53% of the normal and 50% in patient group. Hooked type of acromion was detected in 3% and 31% of the normal and patient group, respectively. CONCLUSION: Protrusion of acromion at TCTV itself was not a criteria of subacromial impingement syndrome, but more than 7 mm below the line of extension from inferior surface of clavicle was meanigful. In SOV, hooked type of acromion was a criteria of subacromial impingement syndrome but curved type is was not a finding of diagnostic significence. Acromial spur formation on TCTV and SOV was important criteria of subacromial impingement syndrome.
