Background and Objectives: Maternal alcohol abuse is considered to be one of the most prominent cause of neurobiological malformations in the postnatal and adult life of the offspring. In this study, we investigated the effects of maternal alcohol drinking on the postnatal development of NPY-containing neuron, and, the influence of thyroxine treatment on the cerebral cortex and hippocampus of pups of alcohol abused mother. Materials and Method: Time-pregnant rats were divided into three groups. Alcohol-fed group A received 35 calories of liquid alcohol diet daily from gestation day 6; control pair-fed group B was fed a liquid diet in dextrin replaced alcohol isocalorically: alcohol + T4 group C received 35 calories liquid alcohol diet and exogenous thyroxine subcutaneously. Results: Group C showed prominent NPY immunoreactivity in the cerebral cortex compared to group A and B at P7. In group C, NPY-containing neurons were widely distributed in the all layers of cerebral cortex after P14. Besides, numerical decrease of NPY-containing neuron as age increases was not found in group C. However, the decrease of NPY-containing neuron was clearly observed in group A compared to group C after P14. In hippocampus, group Band C were appeared similar patterns after P7. Additionally, in group C, NPY immunoreactivity was prominently appeared in CA2 and CA3 at P14 as compared to group B. Conclusions: The present results showed the increase of intensity and number of NPY-containing neurons in cerebral cortex and hippocampus of pups of exogenous T₄ supplemented alcohol-exposed dams as compared to control pair-fed and alcohol-exposed pups at P7. It presumably suggest that NPY-containing neurons might be regulated by the early postnatal growth stimulatory effect of the exogenously supplemented T₄. Therefore, the increase of NPY synthesis caused by maternal administration of exogenous thyroxine may ameliorate fetal alcohol effect, one of the ill effects as a result of the dysthyroid state following maternal alcohol abuse.

Bortezomib is the first clinically available proteasome inhibitor that is clinically effective in the treatment of multiple myeloma. A proteasome inhibitor acts through multiple mechanisms to arrest tumor growth, tumor spread, and angiogenesis. The main adverse effects of bortezomib are gastrointestinal symptoms, cytopenia, fatigue, and peripheral neuropathy. To date, severe paralytic ileus has not been reported as a toxic effect of bortezomib treatment in multiple myeloma. Bortezomib is a novel agent that has only been used clinically for 30 months, so a need exists to further evaluate its toxicity. We report a case of grade Ⅲ (NCI CTCAE v3.0) or grade Ⅳ(SWOG toxicity criteria) paralytic ileus in a 65-year-old man with relapsed multiple myeloma who underwent one cycle of single-agent bortezomib treatment scheduled in a 21-day cycle (1.3 mg/㎥ as a single i.v. bolus on days 1, 4, 8, and 11).

Radiofrequency ablation(RFA), as a form of minimally invasive therapy for hepatocellular carcinoma, has become an important treatment modality. Because of limitation of surgery, RFA has become standard therapy for hepatocellular carcinoma in some situations. But there are some complications of RFA such as bleeding, infection, hematoma, adjacent organ thermal damage including intestinal perforation, needle track seeding, and so on. There are few reports in the literature that systematically evaluate the incidence of needle tract seeding and its associated risk factors. And only 2 cases of needle tract seeding of hepatocellular carcinoma after RFA were reported in Korea. We report a case of needle tract seeding of hepatocellular carcinoma after RFA.

백락주,송진원,송기준,박광숙,최영주,강주일,이용주 대한감염학회 1997 감염 Vol.29 No.6

목적:국내 야서중에 한타바이러스의 숙주는 등줄쥐와 집쥐로 알려져 있으나, 한국에 서식하고 있는 다양한 야생 설치류를 채집하여 한타바이러스에 대한 항체검사를 실시하여 새로운 혈청형의 한타바이러스가 있는지를 혈청학적으로 규명하고자 하였다. 방법:국내에 서식하고 있는 야생 설치류를 1995년 10월부터 1996년 10월까지 7종 551수의 야시와 4종 97수의 소형동물을 채집하여 한타바이러스에 대한 항체검사를 간접형광항체법으로 실시하였다. 결과: 1) 야서 7종 551수와 소형동물 4종 97수를 대상으로 한탄바이러스의 감염율은 등줄쥐 17.2%(29/162), 흰넓적다리붉은쥐 8.7%(2/23), 대륙밭쥐는 25%(2/8), 그리고 땃쥐는 7.1%(1/14)이었다. 그리고 야생토끼는 8.8%(7/80)가 서울바이러스에 대한 항체를 가지고 있었다. 등줄쥐의 양성혈청중 대부분은 서울바이러스와 일부는 푸말라바이러스, 프로스펙트힐바이러스, 뉴욕바이러스와도 교차반응이 있었다. 흰넓적다리붉은쥐 2수와 대륙밭쥐 2수는 5가지 한타바이러스 모두에 교차 반응이 있었다. 2) 다람쥐는 9.5%(28/283)가 채집지역에 관계없이 한탄바이러스에 대한 항체를 가지고 있었고 항체기는 1:16 내지 1:256으로 비교적 낮았으며 서울바이러스, 푸말라바이러스, 프로스켁트힐바이러스와 뉴욕바이러스에 각각 반응하는 것도 일부는 교차반응을 보이는것도 있다. 청설모는 10.3%(7/68)가 한탄바이서르에 대한 항체를 가지고 있었으며 항체가는 1:16 내지 1:1,024이었으며 일부는 교차반응이 있었다. 3) 야생토끼의 서울바이러스에대한 항체양성율은 8.8%(7/80)이었으며 이중에 2수는 한탄바이러스와 교차반응이 있었고, 푸말라바이러스, 프로스켁트힐바이러스, 뉴욕바이러스와는 교차반응이 없었다. 항체가는 1:16 내지 1:64로 비교적 낮았다. 결론:등줄쥐는 한탄바이러스에 의한 감염이지만 흰넓적다리붉은쥐, 대륙밭쥐, 다람쥐 그리고 청설모의 일부는 한탄바이러스가 보다 다른 한타바이러스에 대한 항체가가 높았고 특히 일부 다람쥐 혈청은 푸말라바이러스 혹은 프로스켁트힐바이러스에만 반응하였다. 그리고 야생토끼는 서울바이러스에 대한 감염율이 높은 것으로 보아 국내에 한탄바이러스와 서울 바이러스 이외에 새로운 혈청형의 한타바이러스가 있는 것을 사료된다. Background: Hantavirus are widley distributed in rodents populations even in geographical areas where hemorrhagic fever with renal syndrome(HFRS) has not been reported. Multiple species of Murid and Arvicolid rodents serve as the natural reserviors of hantaviruses. Serologic diagnosis using hantaviral antigens indicates that hantaviruses are widley distibuted in wild rodents. This study were designed to find the distribution of hantaviruses among wild rodents and small mammals in Korea, 1995-1996. Methods: Rodents were trapped alive in selected areas. A total of 551 wild rodents from 7 species and 97 small mammals from 4 species were captured in Korea. Serologic evidence for hantavirus infection were tested using five hantavirus antigens by indirect immunofluorescent antibody technique(IFA). Among 162 Apodemus agrarius, 23 Apodemus peninsulae, 8 Clethrionomys regulus, 6 Microtus fortis, 1 Mus musculus, 283 Tamias sibiricus, 68 Sciurus vulgaris, 14 Crocidura laciura, 80 Lepus sinensis, 2 Capereolus capereolus and 1 Nyctereutes procyonoides. Results: 29 A. agrarius, 2 A. peninsulae, 1 C. laciura, 2 C. regulus, 27 T. sibiricus and 7 S. vulgaris were sero positive agaist hantaan virus and 7 L. sinensis were IF antibody positive against Seoul virus. Some of Tamias sibiricus were only seropositive against puumala virus or prospect hill virus. Conclusion: This data suggests that new serotypes of hantavirus might distribute among rodents in Korea.

Aerobic Exercise Affects Myostatin Expression in Aged Rat Skeletal Muscles: A Possibility of Antiaging Effects of Aerobic Exercise Related With Pelvic Floor Muscle and Urethral Rhabdosphincter

Ko, Il Gyu,Jeong, Jin Woo,Kim, Young Hoon,Jee, Yong Seok,Kim, Sung Eun,Kim, Sang Hoon,Jin, Jun Jang,Kim, Chang Ju,Chung, Kyung Jin Korean Continence Society 2014 International Neurourology Journal Vol.18 No.2

<P><B>Purpose</B></P><P>Aging-induced loss of muscle mass and subsequent reduction of strength is a fundamental cause of frailty, functional decline, and disability. And this may lead to muscular dysfunction, voiding dysfunction, or urinary incontinence due to pelvic muscle weakness induced by aging. Physical exercise has been recommended for the prevention and the treatment of these age-related frail states. We investigated the effects of treadmill exercise on muscle strength, myostatin mRNA and protein expression, and gastrocnemius myocytes proliferation in aged rats to investigate the possible antiaging effects of aerobic exercise on skeletal muscles such as pelvic floor muscles and urethral rhabdosphincter muscle.</P><P><B>Methods</B></P><P>In this study, 5-month-old male Sprague-Dawley rats were used as the young-age group (n=20) and 24-month-old rats were used as the old-age group (n=20). Each group was randomly divided into two groups (n=10 in each group): the sedentary and the treadmill exercise group. The rats in the exercise groups were forced to run on a motorized treadmill for 30 minutes, once a day, for 6 weeks. For this study, a weight load test, hematoxylin and eosin staining, real-time and reverse transcription polymerase chain reaction for myostatin mRNA, myostatin western blot, and 5-bromo-2'-deoxyuridine immunohistochemistry were performed in the gastrocnemius muscle.</P><P><B>Results</B></P><P>The age-induced reduction of muscle mass and strength was associated with a decrease in myocyte proliferation and an increase in myostatin mRNA and protein expression in the gastrocnemius. However, treadmill exercise improved muscle mass and strength through suppression of myostatin mRNA and protein expression, and myocyte proliferation increase in the gastrocnemius against the aging process.</P><P><B>Conclusions</B></P><P>Aerobic exercise is a useful strategy for enhancing muscle function against aging-induced loss of skeletal muscle mass and functions.</P>
