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.

We report a case of 53-year-old man with plasmacytoid transitional cell carcinoma of the urinary bladder, which may be confused with plasmacytoma. The patient initially presented with gross hematuria and dysuria for two months. Cystoscopy and radiologic studies revealed multiple intraluminal protruding masses on the urinary bladder invading perivesical fat tissue. After urinary cytologic examination and cystoscopic biopsy, radical cystectomy and pelvic lymph node dissections were done. Urine cytology showed single cells and poorly cohesive cells with round eccentric nuclei, bi-or multi-nucleation, indistinct nucleoli, coarse chromatin, and abundant basophilic cytoplasm within relatively clear background. The cytologic findings of tumor cells were similar to the plasma cells seen in plasmacytoma. The tumor of the bladder was composed of discohesive, individual cancer cells with diffuse pattern that simulated lymphoma or plasmacytoma. Immunohistochemical and electron microscopic studies clearly established the epithelial nature of the neoplasm. Recognition of this plasmacytoid type of transitional cell carcinoma of the urinary bladder can avoid the misdiagnosis.

PURPOSE:Neopterin is a marker of activation of the T-lymphocyte/monocyte axis. We measured serum neopterin concentration to investigate whether serum neopterin levels are increased in children with Graves' disease and whether serum neopterin measurement can be used as a marker of disease activity in Graves disease. METHODS:Twenty children with Graves' disease(3 boys and 17 girls) and 15 healthy children(7 boys and 8 girls) are enrolled in this study. Serum neopterin concentrations are measured by radioimmunoassay. RESULTS:Neopterin concentration in children with Graves' disease(1.59+/-1.25ng/ml) is not higher than that of healthy children(1.51+/-0.73ng/ml). Neopterin concentration is not influenced by thyroid function and remission state. CONCLUSION: Serum neopterin level in children with Graves' disease can not be used as a marker of activity.

Journal of the Korean Ophthalmological Society 2002;43(12):2513-2518
PURPOSE: To assess the the accuracy and variability in pachymetry measurements obtained by Orbscan and ultrasonic pachymeter in laser in situ keratomileusis (LASIK). METHODS: Thirty two eyes of 16 patients before LASIK were measured by ultrasonic pachymeter and Orbscan. Thirty eyes of 16 patients that had LASIK were measured by ultrasonic pachymeter and Orbscan postoperatively. The theoretical residual corneal thickness was compared to measurements by both instruments in eyes that had LASIK procedures. RESULTS: The ultrasound pachymeter measurements (543.8+/-24.2 micrometer) were thicker than the Orbscan pachymetry measurements, (541.2+/-24.9 micrometer) by mean of 2.7+/-7.4 micrometer (SD), preoperatively. But this is not statistically significant (p>0.05). Postoperatively, the ultrsound measurements were consistent with theoretical residual corneal thickness, 461.8+/-37.4 micrometer versus 467.9+/-30.71 micrometer (p=0.064), while Orbscan measurements were statistically less than the theoretical residual corneal thickness, 433.2+/-48.75 micrometer versus 464.32+/-33.4 micrometer (p<0.001). CONCLUSIONS: In LASIK eyes, the ultrasonic pachymetry was a more accurate measurement of corneal pachymetry than Orbscan topography system.

The hypotony with cyclodialysis after blunt trauma to the eye rarely happens and the cyclodialysis is diagnosed by finding the cleft in the anterior chamber anglel It is treated with cycloplegics conservatively or with surgery. In this study, the authors reviewed the hyphema, the onset of hypotony, the size of cyclodialysis cleft and transient scleral buckling that is one of the surgery in 7 eyes of 7 patients . The hyphema was seen in all cases after blunt trauma to the eyes and the duration between the trauma and the onset of hypotony was average 7.2 days. The traumatic cyclodialyses clefts were half an clock hour in 3 patients and 1 to 4 clock hours in 4 patients . Six patients had an initial conservative treatment, 3 patients required surgical treatment, scleral buckling, for 3 weeks for the full recovery of intraocular pressure.

In general, the long head of the biceps brachii originates from the superior glenoid labrum and the supraglenoid tubercle, crosses the rotator cuff interval, and extends into the bicipital groove. However, rare anatomic variations of the origins of the long head have been reported in the past. In this report, we review the clinical history, radiologic findings, and arthroscopic identifications of 3 anatomic variants of the biceps tendon long head. As the detection of long head of biceps tendon pathology during preoperative radiologic assessment can be difficult without prior knowledge, surgeons should be aware of such possible anatomic variations.
