  • 음식물 쓰레기는 산완충능(buffer capacity)이 충분하지 않아 포집과 운송기간 동안 유기산이 축적될 수 있고 몰리브덴이나 코발트와 같은 미량원소가 부족할 수 있기 때문에 가축분뇨는 음식물 쓰레기와 혼합소화 시 부족한 메탄생성량을 보충할 수 있는 혼합기질로서 적합한 것으로 판단된다. 본 논문에서는 성공적인 혐기공정 설계 및 안정적 운영을 위한 우리 나라 유래 대상기질의 실제성상 특징과 메탄가스 발생사이의 상관성을 알아보고자 하였다. 서울시의 8개 기초자치단체(강남, 강동, 송파, 영등포, 관악, 구로, 동작, 용산)의 음식물 쓰레기 중간 집하장이나 처리시설에서 음식물 쓰레기를 채취하였다. 음식물 쓰레기의 고형물 함량은 평균 16%를 보였고 잠재 메탄발생량은 평균 $446.6STP-m{\ell}/g-VS$로서 $334.8{\sim}567.5STP-m{\ell}/g-VS$의 범위를 가진다. 우분의 고형물 함량과 잠재메탄 발생량은 각각 평균 26%과 $280.6STP-m{\ell}/g-VS$로 타나났다. 잠재 메탄발생량은 고위발열량, 지방 함량, 탄소함량, 수소함량과 양의 상관관계를 가지고 탄수화물 함량과 음의 상관관계를 가지는 것으로 나타났다($r^2>0.8$). 따라서 이러한 기질특성 분석결과를 통해 잠재 메탄발생량을 비교적 정확하게 예측하였다. 본 연구에서는 단일 기질과 잠재 메탄발생량을 분석하였으나 향후는 최대 메탄발생량을 위하여 혼합기질 (음식물쓰레기, 가축분뇨, 수분조절제 등)의 최적조합을 결정하는 연구가 수행하여야 할 것으로 여겨진다.

  • Fibromatosis is benign fibroblastic proliferative lesion with abundant collagenous neo-formation located principally in the abdominal wall and in the upper and lower extremities (Masson & Soule, 1966). Wilkins and Waldron, in 1975, suggested that the title aggressive fibromatosis was a more appropriate term, reflecting the invasive characteristics of the disease. Synonyms listed were extra-abdominal desmoid, juvenile fibromatosis, aggressive infantile fibromatosis and congenital fibrosarcoma. A total of 12% of all fibromatosis arise in head and neck. Fibromatosis of the oral cavity is uncommon and is even more rare when in involve the mandibule. It is a locally aggressive fibrous tissue tumor, generally does not metastasize, but may cause considerable morbility and even death due to local infiltration. The degree of microscopic cellularity is variable, not only from tumor to tumor but also from area to area in the same tumor. Some tumors present with proliferation of mature fibroblasts and a dominating collagenous component : others may show a lack of the tumor in both types. The common histologic denominator appears to be cellular interlacing bundles of elongated fibroblasts, showing little or no mitotic activity and no pleomorphism. Mitosis are not a consistent index of malignancy when found in younger age groups. Fibromatosis still posses difficult problems of diagnosis and treatment. It is frequently recurrent and infliltrates neighbouring tissues. These lesion infliltrate widely and replace muscle, fat, and even bone with fibrous tissue of varying cellularity. Lesion representing fibromatosis in the oral cavity must be carefully evaulated by both surgeon and pathologists to ensure proper diagnosis and treatment planning. When these lesions involve bone, surgeon must be aware of the lesion's potential to perforate the cortex and expand while remaining hidden from the surgeon's view. Careful and precise clinical correlation with histologic appearance is essential to preclude misdiagnosis of fibrosarcoma yet provide surgical treatment plan that provides adequate local excision and long-term follow up. As regards cause, little is known. It is attributed to trauma or alteration in the sex hormone(Carlos, et al, 1986). Clinially, the lesion is reported to be not painful in most cases, but capable of rapid growth. The treatment is essentially surgical excision with wide margin of adjacent uninvolved tissue. Radiotherapy, hormone treatment or chemotherapy are of no use (WIkins et al, 1975 ; Majumudar and Winiarkl, 1978). We report a case of aggressive fibromatosis of 15-year-old with a lesion in the soft tissue of the parotid area that invaded the underlying bone of the mandibular body.

  • Objectives: Two historical evidence supported the concept of Gamrosu. The first one was Jeho-tang, a selected thirst quencher in Chosun Dynasty and the second one was Saeng-Maek-san, Dongeuibogam's recommendation as one of the qi-vigorating summer beverages. Gamrosu is a modified fasting therapy beverage which is manufactured from those two prescriptions and the carbohydrates (420.6 kcal/d). A retrospective observational study was conducted to evaluate the clinical outcomes. Methods: Thirty-three cases were reviewed at three local Korean Medical clinics that each site's participant has finished the modified fasting for 10 consecutive days. Clinical outcomes were reviewed at pre- and post-fasting sessions by retrieving the changes of body composition, blood pressure, blood chemistries & urine tests, and subjective symptoms & fatigue scores. Results: Demographics of the observed participants were 17 of male and 16 of female. Post-Gamrosu session, -6.89% of body weight, -8.97% of body fat mass were reduced with the nutrition indices being improved (P<0.001). -8.72% of systolic blood pressure, -39.86% of serum triglyceride, -6.75% of fast blood sugar and -8.12% of waist circumference were improved (P<0.05). The levels of high sensitivity C-reactive protein (-58.34%), CRP (-43.55%) and eosinophil (-21.30%) showed the significant diminished profiles (P<0.05). Liver/kidney functions and the standard of electrolytes were maintained within normal range in stable manners. The fatigue scale scores indicated significant lower scores. Conclusions: Taken together, obesity-related clinical outcomes after a modified fasting therapy with Gamrosu were sufficiently feasible and the observed findings should be considered for further prospective clinical studies.

  • The objective of this study was to investigate the physicochemical and microbial quality of loin (m. longissimus dorsi) and top round (m. Semimembranosus) in Holstein veal produced from two slaughter age groups (5 and 8 months of age). A total of 20 Holstein calves were randomly selected from a local cattle farm. The slaughtered cold carcasses were vacuum-packaged. The samples were analyzed for proximate composition and physicochemical analyses and stored for 1, 7, 10, 20 and 30 days for microbiological analyses. Fat and protein contents of loin for the 8 month group were higher than those for the 5 month groups (p < 0.05). For both loin and top round muscles, the pH, cooking loss and the shear force values for the 5 month group was higher than those for the 8 month group (p < 0.05). On the other hands, the water-holding capacity (WHC) for the 8 month group was higher than those for the 5 month group (p < 0.05). In terms of meat color, CIE $L^*$ (lightness) for both muscle were higher in the 5 month group than in the 8 month groups. On the other hands, $a^*$ (redness) were higher in the 8 month group than in the 5 month groups (p < 0.05). Total aerobic counts in all samples remained up to 30 days at values less than 7 log CFU/g. However, there was no significant difference for both muscles between the two age groups. The results indicate that Holstein muscles from the 8 month group had desirable quality properties than those from the 5 month group.

  • Nesfatin-1 is a recently discovered anorexigenic peptide which is distributed in several brain areas implicated in the feeding and metabolic regulation. Recently, it has been reported that nesfatin-1 is expressed not only in brain, but also in peripheral organs such as digestive organs, adipose tissues, heart, and reproductive organs. Nesfatin-1 is markedly expressed in the pancreas, stomach and duodenum. Eventually, the nesfatin-1 expression in the digestive organs may be regulated by nutritional status, which suggests a regulatory role of peripheral nesfatin-1 in energy homeostasis. Nesfatin-1 is also detected in the adipose tissues of humans and rodents, indicating that nesfatin-1 expression in the fat may regulate food intake independently, rather than relying on leptin. In addition, nesfatin-1 is expressed in the heart as a cardiac peptide. It suggests that nesfatin-1 may regulate cardiac function and encourage clinical potential in the presence of nutrition-dependent physio-pathologic cardiovascular diseases. Currently, only a few studies demonstrate that nesfatin-1 is expressed in the reproductive system. However, it is not clear yet what function of nesfatin-1 is in the reproductive organs. Here, we summarize the expression of nesfatin-1 and its roles in brain and peripheral organs and discuss the possible roles of nesfatin-1 expressed in reproductive organs, including testis, epididymis, ovary, and uterus. We come to the conclusion that nesfatin-1 as a local regulator in male and female reproductive organs may regulate the steroidogenesis in the testis and ovary and the physiological activity in epididymis and uterus.

  • Protein-energy malnutrition is regarded as one of the public health problems in developing countries as a result of poor feeding practices due to poverty. This study, therefore, aimed at evaluating nutritional quality of a potential weaning food formulated from locally available food materials. The cooking banana fruit(CB) and bambara groundnut seeds(BG) were purchased from local market in Akure, Ondo State, Nigeria. The CB and BG were processed into flours, mixed in ratios of 90:10, 80:20, 70:30 and 60:40 and subjected into proximate, sensory and biochemical analyses using standard procedures. Nutrend(a commercial formula) and ogi(corn gruel, a traditional weaning food) were used as control. The nutritient composition(g/100 g) of the food samples were ranged as follows: moisture 2.94-6.94, protein 7.02-16.0, ash 1.76-2.99, fat 0.76-8.45, fibre 1.52-3.75, carbohydrate 63.84-88.43 and energy 1569.8-1665.7 kcal. The biological value(BV), net protein retention(NPR), protein efficiency ratio(PER) and feed efficiency ratio(FER) of the experimental food samples were significantly(p<0.05) lower than nutrend, but higher than ogi. The haematological variables of rats fed with formulated food samples, commercial formula(nutrend) and traditional weaning food(ogi) were not significantly(p>0.05) influenced by the dietary treatment. However, the values obtained for red blood cell(RBC), white blood cell(WBC), pack cell volume(PCV) and erythrocyte sedimentation rate(ESR) were higher in the experimental food samples than the commercial food. The growth rate of animals fed with experimental food samples were lower than those fed with the nutrend, but higher than those fed with ogi. In conclusion, the nutritional quality of CB and fermented BG mix of 60:40 ratio was better than ogi; and comparable to the nutrend. This implies that it can be used to replace low quality traditional weaning food and the expensive commercial weaning formula.

  • To evaluate the ewe reproductive performances of three Iranian local sheep breeds, namely Moghani, Chal and Zel, 27 rams and 473 ewes were used as the foundation flock in a crossbreeding program. The three breeds were crossed amongst themselves reciprocally. Ram breed and ewe breed showed a two-way interaction on apparent fertility. The Zel ewes showed higher fertility than the Chal and Moghani ewes (94.4 vs 77.3 and 84.6%). Prolificacy among main and individual mating groups were not significantly different (p>0.05). Zel ewes were 22.3 and 14.8% more reproductive (p<0.05) than Chal and Moghani ewes, respectively. Zel and Moghani ewes showed higher (p<0.05) ewe productivity than Chal ewes. Ram breed had a significant (p<0.05) effect on ewe efficiency. The Zel rams were not completely successful to mate with Chal ewes, this caused a to way-interaction between ram and ewe breeds. The Zel ewes mated with Chal and Moghani rams showed 26.1 and 28.5% more efficiency than those mated with Zel rams. This observation strongly supports the use of crossbreeding to improve the efficiency of the Zel ewes. With decreasing lamb mortality, through supplemented feeding of lambs in pre-weaning period, and increasing litter weight, through crossbreeding, it should be possible to improve the efficiency of Zel ewes even better than Chal and Moghani ewes. Small body size of Zel ewes that needs the lower maintenance requirements would be a well advantageous to using Zel ewes as the dam herd to produce commercial lambs in north area of Iran.

  • Phytochemicals are reported to provide various biological functions leading to the promotion of health as well as the reduced risk of chronic diseases. Fat-soluble plant pigments, carotenoids, are extensively studied micronutrient phytochemicals for their potential health benefits. It is noteworthy that specific carotenoids may be responsible for different protective effects against certain diseases. In addition, each carotenoid can be obtained from different types of plant foods. Considering the fact that the phytochemical content in foods can vary according to, but not limited to, the varieties and culture conditions, it is important to establish a database of phytochemicals in locally produced plant foods. Currently, information on individual carotenoid content in plant foods commonly consumed in Korea is lacking. As the first step to support the production and consumption of sustainable local plant foods, carotenoids and total phenolic contents of plant foods commonly consumed in Korea are presented and their potential biological functions are discussed in this review.

  • Zoonoses are those diseases and infections that are naturally transmitted between vertebrate animals and man. At present, approximately 175 diseases caused by virus, rickettsia, bacteria, protozoa and helminthes as well as some of arthropods and the number is continually increasing. Although zoonoses are generally recognized as significant health problems, the actual prevalence and incidence of zoonotic infections is difficult to determine. Medical services in a rural area are scarce and ill persons may have little chance to see a physician. Furthermore, a lack of physician awareness and of appropriate diagnostic support is made often misdiagnosis. In rural Korea, parasitic disease is still important subject in the field of zoonotic infections considering its number and morbidity. Recently there was conspicuous reduction of soil-transmitted parasitic diseases (i.e. ascariasis. hookworms, trichuriasis), but clonorchiasis. intestinal trematodiases and taeniasis are a considerable problem. This is often significantly related to human behavioral patterns based on socio-economic and cultural conditions and linked with the local biologic and physical environment. The most of all parasitic zoonoses to man and animals are the food-transmitted parasitic diseases, and domestic animals such as dog, cat, pig, as well as fat and some mammals, ruminants and birds are act as reservoir hosts. In the present topics, current problems of parasitic zoonoses caused by protozoan infections (i. e. toxoplasmosis, pneumocystosis and cryptosporidiosis) which are the most common opportunistic in AIDS or immunocompromised persons, trematode infections (i.e. clonorchiasis, paragonimiasis and some intestinal tremadodiases). cestode infections such as cysticercosis and sparganosis, and some nematode infections of anisakiasis, thelaziasis and strongyloidiasis, are discussed here those on the occurrence in man and animals and the source of transmission as well as prevention and control measures in Korea.

  • Background Breast-conserving surgery is widely accepted as an appropriate method in breast cancer, and the lateral thoracodorsal flap provides a simple, reliable technique, especially when a mass is located in the lateral breast. This study describes the usefulness of a lateral thoracodorsal flap after breast conserving surgery in laterally located breast cancer. Methods From September 2008 to February 2013, a lateral thoracodorsal flap was used in 20 patients with laterally located breast cancer treated at our institution. The technique involves a local medially based, wedge shaped, fasciocutaneous transposition flap from the lateral region of the thoracic area. Overall satisfaction and aesthetic satisfaction surveys were conducted with the patients during a 6-month postoperative follow-up period. Aesthetic results in terms of breast shape and symmetry were evaluated by plastic surgeons. Results The average specimen weight was 76.8 g. The locations of the masses were the upper lateral quadrant (n=15), the lower lateral quadrant (n=2), and the central lateral area (n=3). Complications developed in four of the cases, partial flap necrosis in one, wound dehiscence in one, and fat necrosis in two. The majority of the patients were satisfied with their cosmetic outcomes. Conclusions Partial breast reconstruction using a lateral thoracodorsal flap is well matched with breast color and texture, and the surgery is less aggressive than other techniques with few complications. Therefore, the lateral thoracodorsal flap can be a useful, reliable technique in correcting breast deformity after breast conserving surgery, especially in laterally located breast cancer.
