Background : Dendritic cells (DCs) are rare leucocytes that are uniquely potent in their ability to capture, process and present antigens to T cells, and so selectively migrate through tissues to reach lymph nodes and spleen where initiation of immune responses takes place. It has been reported that a dense infilteration of dendritic cells correlates with a favorable prognosis in several types of cancer. A similar correlation also has been noted in patients with papillary carcinoma of thyroid. The purpose of this study is to determine whether DCs are generated from peripheral blood monocytes by using cytokines such as GM-CSF. TNF-a and IL-4 and whether cytotoxic T cells activated by DCs attack the papillary carcinoma tissues. Methods : Peripheral blood was obtained from 2 patients with thyroid papillary cancer. DCs were established from monocytes by culturing in the presence of GM-CSF, Flt-3 ligand, TNF-a, and IL-4 for 14 days. At day 14, expression of surface markers typical for DCs was analyzed morphologically. The immunophenotypic features of DCs such as CD1a, CD83, and CD86 were analyzed by phase contrast microscopy. At day 15 DCs were incubated with thyroid cancer tissues and normal thyroid tissues for 7 days. Results : DCs were generated from the peripheral blood monocytes. The generated cells known as circulating DCs attached to the thyroid cancer tissues were observed. The CTLs activated by DCs were observed to attack the papillary carcinoma tissues by scanning electron microscope. However, normal tissues were not attacked by CTLs. Conclusion : DCs can be generated from the peripheral blood monocytes. Furthermore, the CTLs activated by DCs also can attack the papillary carcinoma tissues. These results suggest that DCs can be used as adjuvants for adoptive immunotherapy of papillary thyroid cancer.

Background/Objective : Various methods including upper GI series, endoscopy, ultrasound, CAT scan are used with serum tumor markers, especially CEA and CA 19-9, for the diagnosis and evaluation of gastric carcinoma. In this study the clinical utility of serum CA 72-4 of 300 gastric carcinoma patients for the diagnosis and management of gastric carcinoma was evaluated. Methods : Serum level of CA 72-4 was measured using <Centa> Core CA 72-4 RIA Kit (Packerd, USA). The cutoff level of serum CA 72-4 was 4U/ml. The serum levels were correlated with the stage, the location of lesions, the gross type, the depth of invasion, the nodal and distant metastasis. Results : 1) Overall positivity of CA 72-4 was 32.0% (96 cases). 2) There was no difference in the positivity of serum CA 72-4 according to locations and gross types of the carcinoma, but significant (p<0.05) difference in the positivity of serum CA 72-4 was noted between cases of early gastric carcinoma (12.3%) and advanced gastric carcinoma (37.4%). 3) The positivity of serum CA 72-4 of stage 3 and 4 (49.5%) was significantly (p<0.05) higher than those of stage 1a (12.1%) and 2 (16.0%). Furthermore, 87.5% of the cases of the cases of positive serum CA 72-4 belonged to stage 3 or 4. 4) The positivity of serum CA 72-4 were 12.3%, 14.3%, 34.7% and 52.6% for T1, T2, T3 and T4, respectively, showing relatively good correlation between CA 72-4 positivity and depth of invasion. And 86.5% of the cases of positive serum CA 72-4 belonged to T3 or T4 group. 5) The positivity of serum CA 72-4 of N1 and N2 groups (35.1% and 41.7%, respectively) was significantly (p<0.05) higher than those of N0 group (12.2%) and 89.6% of the cases of positive serum CA 72-4 belonged to node positive cases. 6) In the cases of metastasis present, CA 72-4 positivity was 47.4%, which was significantly (p<0.05) higher than that of metastasis-negative cases (28,4%). Among sites of metastasis, there was no difference in the positivity of CA 72-4. Conclusions : Serum CA 72-4 was not useful as a screening test in the diagnosis of gastric carcinoma, but may be useful in differentiating between early and advanced cases, in determining stage of the disease, depth of invasion, serosal invasion, and especially in detecting nodal metastasis, and also useful when used with imaging modalities of diagnosis.

The immunophenotypic features of DCs such as CDla, CD83, and CD86 were analyzed by phase contrast microscopy. At day 15 DCs were incubated with thyroid cancer tissues and normal thyroid tissues for 7 days. Results: DCs were generated from the peripheral blood monocytes. The generated cells had the classic morphology of DCs. Activated cytotoxic T lymphocytes (CTLs) were observed. Veiled cell known as circulating DCs attached to the thyroid cancer tissues were observed. The CTLs activated by DCs were observed to attack the papillary carcinoma tissues by scanning electron microscope. However, normal tissues were not attacked by CTLs. Conclusion: DCs can be generated from the peripheral blood monocytes. Futhermore, the CTLs activated by DCs also can attack the papillary carcinoma tissues. These results that DCs can be used as adjuvants for adoptive immunotherapy of papillary thyroid cancer.

A Pn10 DNA probe was introduced as a Prevotella nigrescens ATCC $33563^T$-specific DNA probe. In that study, the specificity of the Pn10 was tested with only type or reference strains of 5 oral bacterial species. The purpose of this study is to evaluate the specificity of the Pn10 using the wild type strains of P. nigrescens and is to develop the P. nigrescens ATCC $33563^T$-specific PCR primers based on the nucleotide sequence of the Pn10. The specificity of the Pn10 DNA probe was determined by Southern blot analysis. The nucleotide sequence of Pn10 DNA probes was determined by chain termination method. The PCR primers were designed based on the nucleotide sequence of cloned DNA fragment. The data showed that Pn10 DNA probe were hybridized with the genomic DNAs from P. nigrescens ATCC $33563^T$ and KB6. The Pn10 homologous region, KB6-Pn10, of P. nigrescens KB6 was cloned by PCR and sequenced. The Pn10 and KB6-Pn10 DNA fragments were consisted of 1,875 bp and 1,873 bp, respectively. The percent identity of the two was 98.8% and the divergence of them was 0.6%. The two primer sets (Pn10-F-AC/ Pn10-R-AC and Pn10-F-A/ Pn10-R-A), designed base on the nucleotide sequences of Pn10 DNA probe, were specific to the P. nigrescens ATCC $33563^T$. The two PCR primer sets could detect as little as 4 pg of genomic DNA of P. nigrescens ATCC $33563^T$. These results indicate that the two PCR primer sets have proven useful for the identification of P. nigrescens ATCC $33563^T$, especially with regard to the maintenance of the strain. 본 연구는 Prevotella nigrescens ATCC $33563^T$에 대한 균주 특이 DNA 프로브라고 보고된 Pn10 프로브의 균주 특이성을 한국인에서 분리된 P. nigrescens의 임상분리 균주를 이용하여 검증하고, P. nigrescens ATCC $33563^T$ 균주 특이 PCR 프라이머를 개발하고자 시행되었다. P. nigrescens와 유전학적으로 가장 가까운 Prevotella intermedia를 포함한 구강 내 치주질환 원인균종인 5균종의 표준균주 및 참고균주, 그리고 P. nigrescens와 P. intermedia의 임상분리 균주를 이용하여 Southern blot 분석법을 시행하였다. Southern blot 분석 결과 Pn10 DNA 프로브에 P. nigrescens ATCC $33563^T$ 및 ChDC KB6 두 균주 지놈 DNA가 검출되었다. P. nigrescens KB6 균주에서 Pn10 DNA 프로브와 상동성이 있는 부위를 PCR법으로 증폭(KB6-Pn10)하여 클로닝한 다음 Pn10 DNA프로브와 같이 핵산 염기서열을 결정하여 상동성을 비교하였다. 그 결과 Pn10과 KB6-Pn10의 핵산염기서열간의 Percent identity는 98.8%였으며, divergence는 0.6%였다. Pn10 DNA 프로브의 핵산염기서열을 바탕으로 두 중류 프라이머 쌍(Pn10-F-AC/Pn10-R-AC 및 Pn10-F-A/Pn10-R-A)을 설계 및 제작하여 P. nigrescens ATCC $33563^T$에 대한 균주 특이성을 PCR법으로 검증하였다. 이들 프라이머 쌍들의 민감도(sensitivity) 조사 결과, 이들은 P. nigrescens ATCC $33563^T$ 지놈 DNA 4 pg까지 검출할 수 있음을 알았다. 이상의 연구 결과를 종합하면, Pn10 DNA 핵산염기서열을 바탕으로 설계된 Pn10-F-AC/Pn10-R-AC 및 Pn10-F-A/Pn10-R-A 프라이머 쌍들은 P. nigrescens ATCC $33563^T$를 신속 정확하게 검출하는 수 있어, 균주의 보존적 측면에서 유용하게 이용될 수 있을 것으로 생각된다.

Pheochromocytoma is a catecholamines producing tumor commonly developed from the adrenomedullary chromaffin cells. Clinical manifestations are usually sustained or paroxysmal hypertension, headache, palpitation or other catecholamine induced symptoms, but hemoptysis is very rare. This report is about a patient with pheochromocytoma presented with hemoptysis and chest pain occurred during paroxysm of hypertension, cured by surgical removal of the tumor.
