Constipation is a common clinical problem that comprises of symptoms that include excessive straining, hard feces, feeling of incomplete evacuation and infrequent defecation. Although many conditions, such as metabolic problems, fiber deficiency, anorectal problem, an drug, can cause constipation. This study was examined the effects of Chilsun-Whan on intestinal mucosa and gastrointestinal transit time and plasma lipids in rats. Adult male rats were fed for weeks on diets containing no addition(basal diet group), 5% cellulose(cellulose group) and 2.5% . Chilsun-Whan group(Chilsun-Whan group). The results were as follows; 1. The fecal weght was significantly increased 2 times in Chilsun-Whan administrated group compare to basal diet group. 2. The gastrointestinal transit times was significantly decreased in Chilsun-Whan administrated group compare to basal diet. 3. Carmine red mixed with Chilsun-Whan, as a marker, was administered through a gastric tube for stomach or intracecally by a chronically implanted catheter for colon transit. Small intestinal transit and large intestinal transit time were significantly decreased in Chilsun-Whan administrated group compare to basal diet. 4. The height of jejunal villi was developed in Chilsun-Whan administrated group compare to basal diet The thickness of mucosa and muscle layer of colonic mucosa were significantly developed in Chilsun-Whan administrated group compare to basal diet group. 5. The change of goblet cell in colonic mucosa was increased acid mucin stained alcian blue in Chilsun-Whan administrated group compare to basal diet and cellulose group. 6. HDL-cholesterol of plasma lipid was increased in Chilsun-Whan administrated group compare to basal diet and cellulose groups. Theses results suggests that Chilsun-Whan may be used in prevention and treatment of constipation resulting in increase of fecal weight, decrease of gastrointestinal transit time. development of intestinal villi, intensify of stainability of acid mucin in colon.

The acyl-CoA dehydrogenase, C-2 to C-3 short chain (ACADS) gene is known to be related with fat metabolism, especially coverts the fat to the energy sources in cattle. In human, the mutations in this gene cause SCAD deficiency, which is one of the fatty acid metabolism disorders. The ACADS gene is located on bovine chromosome 17. The objective of this study was to identify SNPs in Hanwoo ACADS gene and identify the relationships with economic traits. In this study, two SNPs, T1570G SNP in exon 2 and G13917A SNP in exon 4, were observed. Moreover, in the coding region, 2 missense mutations, T (Cys) ${\rightarrow}$ G (Trp) mutation at 1570 bp and G (Arg) ${\rightarrow}$ A (Gln) mutation at 13917 bp, were observed. These mutations were subjected to the PCR-RFLP for typing 198 Hanwoo animals. The observed genotype frequency for T1570G was 0.135 (TT), 0.860 (TG) and 0.005 (GG), respectively. Also, 0.900 (GG) and 0.100 (GA) were observed for the G13917A mutation. The association of these SNPs with four economic traits, CW (Carcass Weight), BF (Backfat Thickness), LMA (Longissimus Muscle Area), MS (Marbling Score), were also observed. The results indicated that no significant results were observed in all four traits (P>0.05). This might indicate that further studies are ultimately needed to use the SNPs in ACADS gene in lager populations for effectively used for the marker assisted selection.

Background: Cryptotia is a congenital anomaly in which the upper part of the retroauricular sulcus is absent and buried underneath the temporal skin. Various surgical techniques have been reported for the correction of cryptotia following Kubo's V-Y plasty in 1933. Conventional methods using a local skin flap, skin grafting, tissue expansion, Z-plasty, and any of these combined approaches can result in skin deficiency of the upper auricle. The aim of this study was to develop a new method that improves cosmetic results and has fewer complications. Methods: This study involved four patients in whom five cryptotia deformities were corrected using V-Y plasty and Z-plasty. After elevation of the flap, acellular dermal matrix (ADM; MegaDerm) that was over 5 mm in thickness was applied to the cephalo-auricular angle and positioned to enhance the projection of the ear. Lastly, the flap was transposed to complete the repair. Results: Between January 2014 and February 2018, cryptotia correction with ADM graft was performed in four patients. None of the patients developed a recurrence of cryptotia, and there were no postoperative complications such as wound infection, seroma formation, and dehiscence. In addition, the procedures resulted in a favorable cosmetic appearance. Conclusion: Based on these findings, i.e., no recurrence and a favorable cosmetic result, when using an ADM graft, it is suggested that this technique could be an alternative method of cryptotia correction. It could also lessen donor-site morbidity when compared to autologous cartilage grafting and be more cost-effective than using cartilage from a cadaver.

알킬화제로 잘 알려진 ethane 1,2-dimethane sulfonate(EDS)는 여러 종에서 선택적인 Leydig 세포(LC) 독성과 정소 기능장애에 연구 모델로 널리 사용된다. EDS 투여에 의해 유도된 LC 녹아웃 흰쥐의 경우, 부정소와 저정낭과 같은 테스토스테론 의존성 부속 생식기관들의 급격한 무게 감소가 초래됨이 이전의 연구들에게 보고되었다. 본 연구는 EDS투여가 흰쥐 부속 생식기관에 미치는 영향에 대해 조사한 것이다. 생체 수컷 흰쥐에 EDS를 1회 주사(75 mg/kg, i.p.)한 후 0, 1, 2, 3, 4, 5, 6, 7주 후에 각각 희생시겼다. 정소와 부정소, 저정낭 그리고 전립선의 무게를 각각 측정하였다. 조직의 변화는 hematoxylin & eosin 염색과 광학현미경을 통하여 분석하였다. 생식소와 그 부속기관의 무게는 EDS 처리 후 3주 까지는 점진적으로 감소하였고, 이후 서서히 정상으로 회복되었다. 부정소의 무게는 정상 수준의 60%까지 회복되는 양상을 보였다. 조직학적 결과에서 부정소의 상피세포층은 주사 후 1주에서 3주까지 비대해지는 것이 관찰되었다. 저정낭에서는 주사 후 1주부터 3주까지 상피세포층의 두께가 감소하였다. 전립선 역시 주사 후 1주에서 3주까지 상피세포층의 두께가 감소되고, 4주부터 회복되었다. 본 연구는 EDS 주사에 의해 일시적으로 안드로겐 결핍이 일어난 흰쥐에서 부속 생식기관에 뚜렷한 조직학적 변화가 일어남을 보였다. EDS 모델을 사용하여 이들 안드로겐 의존적인 부속 생식기관의 생리적, 분자적인 조절 기작에 대해 심층 연구할 경우 이들 조직의 정상 및 병리학적 발생과 분화를 이해하는데 도움이 될 것이다.

충전형 강관콘크리트 구조는 강관과 콘크리트 두 재료의 이질적인 재료특성을 상호 보완적으로 발휘하여 구조적 성능향상을 꾀한 것으로서 제구조 특성상 우수한 구조형식이라 할 수 있다. 강관으로 구속된 콘크리트가 중심축력을 받게 되면 내부의 콘크리트는 압괴에 의한 체적 팽창을 외부의 강관에 의해 구속 받게 되므로 3축 압축응력 상태로 되어 압축강도가 증대된다. 또한 콘크리트의 압괴에 의한 탈락 현상이 방지되므로서 단면의 결손이 없어져 내력 저하가 작아진다는 잇점을 가진다. 따라서 본 연구에서는 원형강관으로 구속된 내부 콘크리트의 구조적 거동 특성을 규명하기 위한 것으로서 폭두께비와 충전 콘크리트의 강도를 주요 변수로 하여 일련의 실험을 통하여 강관으로 구속(3축 응력)된 콘크리트의 구조적 거동 특성을 고찰하였다. 일련의 실험을 통하여 얻어진 결론을 요약하면 다음과 같다. (1)강관에 의한 콘크리트의 구속효과는 강관의 폭두께비와 충전 콘크리트의 강도가 낮을수록 현저하며, 원형강관으로 구속된 내부 콘크리트는 최대내력시의 변형능력에 있어서 횡방향 구속이 없는 콘크리트보다 4~7배 정도까지 증대시켜 연성효과를 높일 수 있을 것으로 기대된다. (2)콘크리트의 구속계수를 이용하여 강관으로 구속된 내부 콘크리트의 강도와 콘트리트 충전강관 기둥의 최대내력을 산정할 수 있는 식을 제시하였다.

Accurate and optimal water supply to cereal crop is critical in growing stalks and producing maximum yields. Excessive soil moisture may cause nutrient deficiencies and oxygen deficiency. Excessive soil water during crop growth stages results in decrease of yields. In Korea, the largest agricultural lands are paddy fields. Recently, upland crops are cultivated in paddy field soils to reduce overproduced rice in Korea. In order to success this policy, it is necessary to fully understand crop response to excessive soil moisture condition from paddy field soils. Adzuki bean is one of major legumes which provide protein in daily diet. Adzuki bean has been well know its weakness to excessive soil moisture condition, In order to obtain optimal yields of adzuki bean from paddy field cultivation, it is necessary to understand response of adzuki bean under different soil moisture conditions. This study investigated characteristics of growths, yields and response degree of water stress from adzuki bean. Three cultivars were selected for this study; Chungju, Hongeon, and Arari. All adzuki beans were cultivated in a paddy field which was divided into three sections with different soil moistures. The paddy field was located in Milyang, Gyeongsangnam during 2016. One section of the paddy field had the greatest average soil moisture content as 35.1% during adzuki bean cultivation (very poor). The second greatest soil moisture section had 32.6% (somewhat poor) and the smallest soil moisture section had 28.9% of soil moisture (somewhat well). During cultivation of three cultivar adzuki beans, soil moisture contents and groundwater levels were monitored. All the characteristics of growth and yield components were measured; height, thickness, 100 seed weights etc. Stress index values were calculated by Stress Day Index (SDI). All cultivars had the greatest yields from somewhat well section. Chungju had the greatest yields throughout all three sections compared to other cultivars. Chungju had 81% greater yield than Hongeon which had the smallest yield from somewhat well section. Arari set in middle from all sections. However there was no significant differences yields from very poor and somewhat poor sections. Leaf SPAD values tended to decrease and stable carbon isotope values increased as soil moisture increased. However, Chungju had no difference across different soil moistures in SPAD and stable carbon isotope values, while Hongeon had the greatest differences across sections. These trends followed by SDI values. Chungju had the smallest SDI values compared to other cultivars, which meant that Chungju was the strongest tolerance against excessive soil moisture than other cultivars. All three cultivars showed severe decrease of yields from very poor and somewhat poor sections. Arari and Hongeon showed great decrease from somewhat well section compared to yields from upland soil. These two cultivars may not be proper cultivating in paddy fields. In conclusion, adzuki bean is very sensitive to soil moisture condition and detailed soil managements are required to obtain optimal yields of adzuki bean from paddy field cultivation.
