A seven-year old female captive Japanese macaque (Macaca fuscata) was mobbed by its cage mates and subsequently died due to trauma. An incidental finding of multiple biliary cystadenoma in the liver is herein reported. Grossly, multiple small cysts were observed throughout the surface of the liver. One particular cyst that measured 1.3×1.2×1.0 cm and contained mucinous fluid was observed in the center of the liver. Microscopically the cysts were lined by biliary epithelium that varied from simple cuboidal to columnar cells. Signs of malignancy and metastasis to other organs were not observed. This is the first report of biliary cystadenoma in Japanese macaque.

A 9-year-old male poodle dog exhibited a white to yelow 3.0. 2.0. 3.9 cm mass in the left testicle withHistopathologically the mas consisted of seminoma and sertoli cell tumor (SCT). Seminoma was characterized withdiffuse solitary pattern in which tumor cells had polygonal nuclei and clear cell border. SCT was composed of compactneoplastic cells with small nuclei and indefinite cytoplasm. The tumor was occupied mainly with SCT. SCT and seminomawere observed occasionally in the same lesion. From these results, this case was diagnosed as concurrent seminomaand SCT in the left cryptorchidism and monorchidism. To our knowledge, this is the first report of concurrent occurrenceof seminoma and SCT in a dog with cryptorchidism and monorchidism in Korea.

This study was carried out to examine proliferative activity and expression of c-myc oncoprotein and p2lras in normal and preneoplastic rat livers induced by an in vivo mid-term chemical carcinogenesis assay. Sixty, six-week-old male specific pathogen free Sprague-Dawley male rats were randomly divided into five groups. Group I was received a single intraperitoneal(IP) dose(200mg/kg) of diethylnitrosamine(DEN). Group 2(10 rats) was operated partial hepatectomy(PH) and Group 3 was received IP(200mg/kg) DEN, fed two weeks later with 500ppm of phenobarbital(PB). Group 4 was received IP(200mg/kg) DEN, fed two weeks later 500ppm(PB) and PH at week 3 after the onset of experiment. While group 5(20 rats) was not treated and used as a control group. All the rats were sacrificed at age 14 weeks except 10 rats from group 5 were sacrificed at the onset of experiment. Livers of all rats were examined for 5-bromo-2'-deoxyuridine(BrdU) incoporation, proliferating cell nuclear antigen(PCNA), silver-binding nucleolar organizer regions(AgNORs) counts per nucleus and expression of c-myc oncoprotein and p21ras. Both the number and area of the preneoplastic lesions were significantly(p<0.01) compared to other groups. A significant(p<0.01) increase in immunoreactive cells were detected in preneoplastic hepatocytes in Groups 3 and 4 by PCNA and BrdU immunohistochemical stain. The number of the positive cells were significantly(p<0.05) lower in normal 14-week-old rats than those of 6-week-old rats. The results showed that proliferative activity of the hepatocytes was increased by treatment with DEN, PH and PB. Meanwhile, AgNORs counts per nucleus were significantly(p<0.05) increased in the preneoplastic hepatocytes of rats in both groups 3 and 4. The expression of c-myc oncoprotein and p21ras were more readily localized within the hepatic preneoplastic lesions such as hyperplastic nodules. Especially, group 4 showed significantly (p<0.05) overexpressed levels compared to groups 1 and 3. These findings suggest that PCNA, BrdU and AgNORs are significantly increased and c-myc oncoprotein and p21ras are significantly overexpressed in hepatic preneoplastic lesions induced by mid-term carcinogenesis. So these parameters can be an effective markers for hepatic prencoplastic lesions.

Traumatic Peripheral Arterial Injury with Open Repair: A 10-Year Single-Institutional Analysis

조호성,허업,이충원,송승환,김선희,정성운 대한흉부외과학회 2020 Journal of Chest Surgery (J Chest Surg) Vol.53 No.5

Background: We report our 10-year experience with traumatic peripheral arterial injury repair at an urban level I trauma center. Methods: Between January 2007 and December 2016, 28 adult trauma patients presented with traumatic peripheral arterial injuries. Data were retrospectively collected on demographic characteristics, the mechanism of injury, the type of vascular injury, and physiological status on initial assessment. The analysis also included the Mangled Extremity Severity Score (MESS), Injury Severity Score, surgical procedures, and outcome variables including limb salvage, hospital stay, intensive care unit stay, and postoperative vascular complications. Results: Four (14.3%) patients required amputation due to failed revascularization. MESS significantly differed between patients with blunt and penetrating trauma (8.2±2.2 vs. 5.8±1.3, respectively; p=0.005). The amputation rate was not significantly different between patients with blunt and penetrating trauma (20% vs. 0%, respectively; p=0.295). The overall mortality rate was 3.6% (1 patient). Conclusion: Blunt trauma was associated with higher MESS than penetrating trauma, and amputation was more frequent. In particular, patients with blunt trauma had significantly higher MESS than patients with penetrating trauma (8.2±2.2 vs. 5.8±1.3, respectively; p=0.005), and amputation was performed when revascularization failed in cases of blunt trauma of the lower extremity. Therefore, particular care is needed in making treatment decisions for patients with peripheral arterial injuries caused by blunt trauma.

Spontaneous subcutaneous cysts were detected from three dogs, being a 4-year-old male shih tzu, an 11-month-old female britany spaniel and a 9-month-old male mongrel. All the cysts were occurred around the joints (one elbow's and two shoulderes', respectively). After surgical removal, the lesions did not recur for 6 months follow-up. Neither cyst communicated with the joint cavity. Grossly, the subcutaneous ovoid cysts had moderate to abundant mucinous fluid. Histologically, the cyst wall consisted of inner myxomatous and outer immature connective tissue. Some parts of the cyst wall had various stages of myxoid metaplasia of collagen tissue leading to new cyst formation. The true lining cells of the inner cyst wall were not observed in all the cysts. From these results, these cases were diagnosed as subcutaneous ganglion cysts. This is the first report of canine subcutaneous ganglion cysts in Korea.

As the IoT-based hyper-connected society grows, public-key cryptosystem such as RSA is frequently used forencryption, authentication, and digital signature. Public-key cryptosystem use very large (safe) prime numbers toensure security against malicious attacks. Even though the performance of the device has greatly improved, thegeneration of a large (safe)prime is time-consuming or memory-intensive. In this paper, we propose ET-MR andET-MR-MR using Euler sieve so it runs faster while using less memory. We present a running time prediction modelby probabilistic analysis and compare time and memory of our method with conventional methods. Experimentalresults show that the difference between the expected running time and the measured running time is less than 4%. In addition, the fastest running time of ET-MR is 36% faster than that of TD-MR, 8.5% faster than that of DT-MRand the fastest running time of ET-MR-MR is 65.3% faster than that of TD-MR-MR and similar to that ofDT-MR-MR. When k=12,381, the memory usage of ET-MR is 2.7 times more than that of DT-MR but 98.5% lessthan that of TD-MR and when k=65,536, the memory usage of ET-MR-MR is 98.48% less than that of TD-MR-MRand 92.8% less than that of DT-MR-MR. 요 IoT 기반의 초연결사회가 되어감에 따라 암호, 인증, 전자서명 등을 위해 RSA와 같은 공개키암호시스템이 빈번하게 사용되고 있다. 공개키암호시스템은 악의적인 공격으로부터 보안성을 확보하기 위해 크기가 매우 큰 (안전)소수를 사용하는데 기기의 성능이 크게 발전하였음에도 불구하고 크기가 큰 (안전)소수생성은 수행시간이 오래 걸리거나 메모리를 많이 요구하는작업이다. 본 논문에서는 수행시간과 사용공간의 효율을 높이기 위해 오일러체(Euler sieve)를 사용하는 ET-MR 소수검사법과 ET-MR-MR 안전소수검사법을 제안한다. 제안한 검사법을 확률적으로 분석한 수행시간 예측 모델을 제안하고 기존 방법들과 수행시간, 메모리 사용량을 비교하였다. 실험결과, 이론적 예측시간과 실제 수행시간의 차이는 거의 없었으며(4%미만)각 알고리즘이 가장 빠를 때의 수행시간을 비교하면 ET-MR이 TD-MR보다 34.5%, DT-MR보다 8.5% 더 빨랐으며,ET-MR-MR이 TD-MR-MR보다 65.3% 더 빨랐고, DT-MR-MR과는 비슷하였다. 공간의 경우 k=12,381일 때 ET-MR이DT-MR보다 약 2.7배 더 사용했지만 TD-MR보다 98.5% 더 적게 사용하였고 k=65,536일 때 ET-MR-MR이 TD-MR-MR보다 98.4%, DT-MR-MR보다 92.8% 더 적게 사용하였다
