Background/Aims: Recent epidemiologic studies have shown a continued increase in colorectal cancer incidence among younger adults. Little is known about the factors that contribute to the development of young-onset colorectal neoplasia (CRN). Methods: A cross-sectional analysis was performed for individuals younger than 40 years who underwent colonoscopy in Seoul St. Mary’s Hospital and its affiliated health screening center. High-risk CRN was defined as adenoma or sessile serrated lesion ≥ 10 mm, with three or more adenomas, villous histology, high grade dysplasia, or carcinoma. Results: Of these 13,621 included participants, 2,023 (14.9%) had one and more CRN. Young patients with CRN tended to be elderly, male, obese, smoker, having a habit of drinking, and having comorbidities such as hypertension, dyslipidemia, diabetes, and chronic kidney disease. In a multivariate analysis adjusted for age, sex, obesity, smoking status, and alcohol intake, old age (odds ratio [OR], 1.086; 95% confidence interval [CI], 1.054 to 1.119), male sex (OR, 1.748; 95% CI, 1.247 to 2.451), obesity (OR, 1.439; 95% CI, 1.133 to 1.828), and smoking (OR, 1.654; 95% CI, 1.287 to 2.127) were independent risk factors for overall CRN. Obesity and smoking as two modifiable factors increased the risk for high-risk CRN even more than for overall CRN (OR, 1.734; 95% CI, 1.168 to 2.575 and OR, 1.797; 95% CI, 1.172 to 2.753, respectively). Conclusions: Obesity and smoking were modifiable risk factors for CRN in young adults. They increased the risk for highrisk CRN even more than for overall CRN. A colonoscopy might be beneficial for young individuals with these factors.

<P>Brain cell death after intracerebral hemorrhage may be mediated in part by an apoptotic mechanism. Colostrum is the first milk produced by mammals for their young. It plays an important role in protection and development by providing various antibodies, growth factors and nutrients, and has been used for various diseases in many countries. In the present study, we investigated the anti-apoptotic effects of bovine colostrum using organotypic hippocampal slice cultures and an intracerebral hemorrhage animal model. We performed densitometric measurements of propidium iodide uptake, a step-down avoidance task, Nissl staining, and caspase-3 immunohistochemistry. The present results revealed that colostrum treatment significantly suppressed N-methyl-D-aspartic acid-induced neuronal cell death in the rat hippocampus. Moreover, colostrum treatment improved short-term memory by suppressing hemorrhage-induced apoptotic neuronal cell death and decreasing the volume of the lesion induced by intracerebral hemorrhage in the rat hippocampus. These results suggest that colostrum may have a beneficial role in recovering brain function following hemorrhagic stroke by suppressing apoptotic cell death.</P>

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>

The purpose of this study was to investigate the change of consumers' values as appeared in advertisements. Advertisements in men's magazine from 1976 to 1996 were classified by VALS1 program. The results were as follows. 1. There was a significant trend that advertisements with outer-directed value decreased while the ones with inner-directed value increased. 2. In case of outer-directed group appeared in advertisements, There was a tendency that the hierarchy of needs shifted from emulators to achievers. However, the shift in hierarchy of needs in inner-directed group was not significant. 3. Even though the advertisements with material value were predominant, there was a tendency that the advertisement with material value decreased while the ones with human value increased.

A. wakegi Araki의 배발생 캘러스 유도에는 2,4-D의 단독 첨가가 보다 효과적이었으나 2,4-D의 농도가 높을수록 기형배의 배발생율이 높았다. BA를 혼합첨가하였을 때는 기형배가 보다 많이 발생하였다. 외식편의 부위별로는 경정, 인편, 엽조직 중, 경정이 배형성을 위한 외식편으로 가장 좋았으며 그 다음 인편, 엽조직 순으로 정상적인 배도 가장 많이 발생하였다. Sucrose 7%에서 배발생 callus 유도가 가장 좋았지만 기형 배의 발생율도 가장 높았다. 재분화 식물체의 염색체 변이는 인편유래 callus에서보다 경정유래 callus에서 높았다. Explant source, growth regulators and sugar contents in the culture media suitable for in vitro plant regenerations through somatic embryogenesis in Allium wakegi Araki were examined. Adition of 2,4-D alone was more effective on embryogenic callus induction than its addition in combination with BA. The embryogenic calluses induced on the media containing 2,4-D at high concentration or 2,4-D in combination with BA produced abnormal embryos at high frequency. Stem apex was the best explant source for normal embryo production, followed in order by scale and in vitro leaf segments. sucrose at 7% resulted in the best embryogenic callus induction though the callus produced abnormal embryos at highest frequency. The highest level of chromosomal variation was shown in the regenerants from the shoot apex-derived embryogenic callus.

ABSTRACT This study was conducted to determine influence of planting date, seeding rate and phosphate rate on main growth, characters, yield and chemical composition of senna from March 11, 1998 to December in Cheju Province. Days to flowering was lessened as planting date was delayed. The plant height of senna was the longest at 31 March planting (99cm) than at the other planting date. Stem diameter, number of leaves were increased at 31 March but number of branches was not affected by planting date. And number of withering leaves were increased as planting date was earlier. Fresh forage yield per lOa, for senna was the greatest (4,660kg) at 31 March planting, the second was 4,397kg at 1 April planting and the reduced the 3,473kg at 11 March planting. Also dry matter yield per lOa, crude protein yield and total digestable nutrient (TDN) yield was nearly the same tendency. Crude protein, crude fat percent was the greastest at 11 March planting and than decreased with further increased at planting date. Crude ash and crude fiber percent was decreased tendency as planting date was delayed. Nitrogen free extract (NFE), TDN percent was increased tendency as planting date was delayed. SPAD reading value of leaves had an efficiency increased as planting date was delayed.
