Background: The aim of our study was to evaluate the utility of thyroglobulin(Tg) measurement in fine-needle aspiration(FNA) for detecting cervical lymph node metastases from papillary thyroid cancer(PTC). Materials and Methods: We performed ultrasonography-guided fine-needle aspiration cytology(FNAC) and Tg-FNA for 49 ultrasonographically suspicious lymph nodes in 42 PTC patients. Twenty eight patients were waiting surgery and the remaining 14 patients had undergone thyroid surgery for papillary thyroid cancer. The final diagnosis were determined based on the results of histological examination(n=49). Results: Lymph node metastasis were confirmed in 46 lymph nodes. FNAC detected 39 metastatic lymph nodes, and Tg-FNA detected 41 metastatic lymph nodes. Two lymph nodes with a negative results on both methods had metastatic lymph nodes on the results of histological examination. The sensitivities of FNAC, Tg-FNA and combined both methods were 84.7%, 89.1% and 97.8%, respectively. Conclusion: Ultrasonography with both FNAC examination and Tg measurement in FNA washout is highly sensitive and give important information for detecting lymphnode metastasis in patients with papillary thyroid cancer.

Purpose : This study examined the effects of college students’ occupational value and social support on their career decision status. Methods : This research was conducted between May 6 and May 30 in 2023 with 228 college students from city B in South Korea as the study participants. The frequency, percentage, mean, and standard deviation of the collected data were analyzed, while t-test, ANOVA test, Scheffe’s test, Pearson correlation coefficient, and a multivariate regression analysis were conducted using the SPSS/WIN 22.0 program. Results : The analysis revealed that the research subjects had an average occupational value of 3.58±.44, social support of 4.18±.56, and a career decision status of 2.82±.59. Notably, a significant difference in the career decision status of the students was observed with regard to their fields of major (F=2.36, p=.019), However, no other variable demonstrated a significant difference. The confidence level pertaining to career decision-making was found to be positively correlated with the pursuit of status and self-direction (r=.25, p<.001), pursuit of creativity (r=.16, p=.017), pursuit of relationship (r=.35, p<.001), pursuit of diversity and change (r=.16, p=17), pursuit of interest (r=.19, p=.003), pursuit of compensation (r=.29, p<.001), pursuit of professionalism (r=.46, p<.001), material support (r=.25, p<.001), appraisal support (r=.35, p<.001), informational support (r=.32, p<.001), and emotional support (r=.29, p<.001). Moreover, the indecision level related to career decision-making demonstrated a positive correlation with the pursuit of excellence (r=.17, p=.010). The factors that affected the confidence level of career decision-making included appraisal support (β=.29, p<.001) and pursuit of compensation (β=.19, p=.003), whose collective explanatory power was 15 %. It was further observed that appraisal support (β=-.27, p<.001), pursuit of professionalism (β=-.16 p=.017), pursuit of excellence (β=.17, p=.005), and the field of major (β=-.16, p=.012) largely influenced the indecision level related to career decision-making, together bearing an explanatory power of 17 %. Conclusion : The results of this study have important implications for enhancing college students’ career decision status. Moreover, further research investigating the diverse variables that affect students’ career decision status is necessary, along with effective endeavors to improve education and develop programs that positively affect college students’ career decision status.

Background: The aim of our study was to evaluate incidental thyroid cancer in a woman who underwent breast ultrasonography, and to determine the prevalence of thyroid cancer and the different characters of occult thyroid cancer between breast cancer and non breast cancer group. Methods: From January 2008 to July 2009, we examined thyroid gland during routine breast ultrasonography. They were classified into four categories according to ultrasonographic finding: negative, benign, indeterminate and malignant. Ultrasound-guided fine-needle aspiration biopsy was carried out for all malignant lesions and some of the indeterminate lesions. We compared the cases of pathologically proven thyroid cancer in two groups; a breast cancer group, and a non-breast cancer group. Results: Among the 3937 cases, 1.37%(54/3937) of all women were confirmed to have thyroid cancer by surgery. Pathologically proven thyroid cancers were identified in 26 of the 1410 breast cancer patient, and 28 of the 2527 non breast cancer patients. The mean diameter of thyroid nodule was 1.17cm and 1.05cm, respectively. Conclusion: The incidence of thyroid cancer was significantly higher in breast cancer group. The routine concurrent breast and thyroid ultrasonographic examinations were helpful in detecting of thyroid cancer in breast cancer womans.

Testosterone과 Cyclic AMP-theophyllin이 흰쥐 부정소의 미세구조 및 몇 가지 효소활성에 미치는 영향

정경순,최임순 한국통합생물학회 1988 동물학회지 Vol.31 No.1

Testosterone과 cyclic AMP(cAMP)가 부정소에 미치는 영향을 조사하기 위하여 흰쥐의 복강내로 testosterone 및 cAMP를 투여하여 acid phosphatase(ACP),alkaline phosphatase(ALP), lactate dehydrogenase(LDH)의 활성도를 측정하였으며 상피세포내 미세구조의 변화를 전자현미경으로 관찰하였다. 그 결과 거세한 실험군에서 ACP활성도는 거세 후 3일째까지 감소하기 시작하였으며 ALP활성도는 5일째,LDH활성도는 7일째부터 각각 감소하였다. 또한 거세 후 14일째 부터 testosterone을 7일간 투여한 경우 ACP와 ALP의 활성도는 5일간 계속 투여하였을 때,LDH의 활성도는 7일간 계속 투여하였을 때만 각각 유의성있게 증가하였다. cAMP 및 cAMP-theophyllin을 투여한 경우 LDH 및 ACP의 활성도가 증가하였으나 그 증가폭은 큰 의미가 없었다. ALP의 활성도는 두 가지의 경우에서 모두 증가를 나타내었다. 미세구조를 관찰한 결과는 거세한 실험군에서 골지체가 점차 변형되어 층상구조가 없어지며 미토콘드리아도 파괴되었고 상당수 존재하던 부동모 (stereocilia)도 파괴되었다. 이 경우 testosterone투여시 파괴되었던 고리지체, 미토콘드리아 및 부동모가 회복되었고 cAMP 및 cAMP-theophyllin 을 투여하였을 때는 골지체 및 여러 세포기관들이 대조군과 같은 수준으로 회복되었으나 부동모는 거세군과 같은 수준으로 관찰되었다. 이상의 결과는 부정소액에서 정자성숙시 나타나는 효소활성도 증가와 유사하게 나타났는데, 이것은 정자↔부정소액↔부정소 상피세포 와 같은 상호작용을 통하여 정자성숙이 이루어지며 이는 상피세포에서 합성된 물질이 부정소내 강으로 방출된다는 것을 의미하며 cAMP를 처리하였을 경우 효소활성도 증가 및 여러 세포소기관의 회복 등 testosterone과 유사한 작용을 나타내는 것은 cAMP가 웅성호르몬 작용시 화확적으로 전달자로 작용할 수 있다는 가능성을 나타내는 것으로 생각된다. This study was made to investigate the effect of testosterone and cyclic-AMP (cAMP) on rat epididymis. Peritoneai injections of testosterone and cAMP to rats were earned out The activities of acid phosphatase (ACP), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) were measured and ultrastructural changes of luminal epithelial cells were observed. As a result, the activity of ACP was significanily decreased on the third day, that of ALP on the fifth day and that of LDH on the seventh day respectively in castrated group. In addition, the activities of ACP and ALP were significanily increased when treated with testosterone for 5 days, that of LDH when treated with testosterone for 7 days. In case of cAMP and cAMP - theophylline injection, the activities of ACP and LDH were increased but the range of increase was of no significance. However a significant increase in the activity of ALP was seen on both cases. On electron microscopic examination, gradually deformed Golgi complex, destructed mitochondria and disrupted stereociha were observed in castrated group. In case of testosterone injection, disrupted Golgi complex, mitochondria and stereocilia showed recovery. When cAMP and cAMP-theophylline were injected as an alternative, various cytoplasmic organelles as well as Golgi com- plex were recovered but stereocilia remained unrecovered.

Purpose: The purpose of this study is to evaluate the radiologic findings of the extraosseous Ewing's sarcoma. Materials and Methods: Six patients with pathologically confirmed extraosseous Ewing's sarcoma were retrospectively reviewed. Patients included two men and four women with an average age of 21.5 years (age range 9-48 years). Plain radiographs (six patients), magnetic resonance (MR) images (five patients), computed tomographic (CT) scans (three patients) and whole body scintigraphy (two patients) were reviewed and analyzed. Images were evaluated with regard to lesion location, size, margin, muscle or bone involvement and intrinsic imaging characteristics on CT and MRI. Results: The tumors were located in the thigh (three patients), back (two patients) and upper arm (one patient). The tumors ranged in size from 2.3 cm to 7.5 cm (mean, 5.2 cm), were mainly well circumscribed and showed no evidence of calcification prior to treatment. Margins were well defined in four out of the six patients. Four patients had subcutaneous lesions and the other two patients had intramuscular lesions. Muscle (two patients) and bone invasion (one patient) were present. The masses were heterogenous low signal intensity on T1 weighted images and heterogeneous high signal intensity on T2 weighted images compared with muscle. Heterogeneous enhancement within the lesion was observed in all patients on CT and MRI. Whole body scintigraphy using Tc-99 m MIBI showed increased uptake in the masses of two patients. Conclusion: Extraosseous Ewing's sarcomas were frequently seen as a well-circumscribed ovoid mass with nonspecific findings on CT and MRI. Despite being a relative rare tumor, it should be included in the differential diagnosis of a non-calcified soft-tissue mass, especially in subcutaneous tissue. 목적: 골격외 유잉육종의 영상소견을 분석하고 감별진단에 도움이 되는 소견이 있는지 알아보고자 하였다. 대상과 방법: 병리학적으로 확진된 6명을 대상으로 후향적으로 분석하였다. 단순촬영은 모든 환자에서 시행하였으며, MRI가 5예, CT가 3예였으며 전신 섬광조영술(whole body scintigraphy)을 2예에서 시행하였다. CT나 MRI에서 종괴의 위치, 크기, 경계, 주위 조직과의 관계를 분석하였다. MRI 에서는 종괴의 신호강도, CT에서는 종괴의 음영을 관찰하였다. 또한 MRI와 CT에서 종괴의 균질성과 조영증강정도를 살펴보았다. 결과: 종괴의 위치는 대퇴부(thigh)가 3예로 가장 많았고, 배부(back)가 2예, 상지가 1예였다. 종괴의 크기는 장경을 기준으로 평균 5.2 cm이었다. 4예에서 주위 정상 조직과의 경계가 잘 구분되었다. 피부하(subcutaneous)가 4예, 근육내(intramuscular)에 위치하는 경우가 2예였다. 주위 근육을 침범한 예가 2예, 골을 침범한 경우가 1예였다. 전예에서 내부는 불균질성을 보였고 MRI를 시행한 5예 중 4예는 T1강조영상에서 주위 근육과 비교하여 저신호강도를 보였으며 T2강조영상에서는 모두 불균질한 고신호강도를 보였다. 전예에서 불균질한 조영증강을 보였다 Tc-99 m MIBI를 이용한 전신 섬광조영술을 시행한 2예에서 종양부위의 섭취가 증가되었다. 결론: 골격외 유잉육종은 비교적 경계가 분명한 종괴로 MRI나 CT에서 비특이적인 소견을 보이지만 비교적 젊은 연령에서 석회화가 없는 불균질한 연부조직 종양이 피부하에서 발생할 때 비록 드물지만 감별진단에 포함해야 할 것으로 생각한다.
