본 연구는 cytochrome B 유전자의 PCR-RFLP 분석기법을 이용하여 다양한 가금류 식육자원 및 각종 가공 육제품의 원료육에 대한 정확하고 재현성 높은 축종 및 육종 감별기술을 개발하기 위하여 수행되었다. 국내에서 유통되고 있는 종간 근연관계가 높은 3종의 가금육(닭, 칠면조 및 오리)의 육류에서 분리한 DNA 시료를 대상으로 cytochrome B 유전자의 특정 염기서열을 포함하는 primer를 설계 제작하여 PCR-RFLP 분석을 실시하였다. 각 축종의 근육조직으로부터 genomic DNA를 추출하고 PCR 증폭 반응을 수행한 후 얻어진 PCR 증폭산물(359 bp)을 두 종류의 제한효소(HaeШ 및 Hinf I)로 각각 절단한 결과 특히, HaeШ 제한효소에서 가금류의 축종 간 그리고 제한효소 간에 명확한 차이를 보이는 종 특이적인 PCR-RFLP marker를 검출하였다. 따라서, 본 연구에서 개발한 cytochrome B 유전자의 가금류 종 특이적 PCR-RFLP marker는 가금류의 식육 및 가공 육제품의 육종 및 축종 판별에 매우 유용한 DNA marker로 이용될 수 있을 것이다.

Giant cell reparative granuloma (GCRG) is an uncommon benign lesion that is most commonly found in the mandible and maxialla, and is a very rare condition in finger. We report an unusual case of GCRG arising in the index finger of a 21-year-old man. Histology was characteristic of giant cell reparative granuloma.

Salted and dried yellow corvenia(Pseudosciaena manchurica), so called 'Gul-bi', is one of nation-widely consuming fish foo::ls. It is suitable for a long term preservation and its pro-duce is also a great deal on sea food processing in this country. The texture of 'Gul-bi', however, have often appeared to be a delicate factor for the quality of the product. The loss or dislocation of fat in the tissue of the fish resulted by salting and drying is believed to profoundly relate to the texture of product. In this paper, the tissue of yellow corvenia and movement of fat were microscopically observed before salting, immediately after salting, and after drying and the results observed in the tissues dry salted, brine salted, and brine salted with the addition of BHA were compared. The cross section of yellow corvenia muscle showed that a distinctive border by connective tissue between white and red muscle could not be seen in general, and red muscle was surrounded by hypodermic fatty tissues. In the tissue of fresh yellow corvenia, the fat was mainly distributed in hypodermic fat layer which located under the corium while rarely distributed in white muscle. It was found that some parts of the fat in the tissue were permeated into intermuscular tissue passing through the connective tissues during salting. The result Was the same in both dry-salting and brine-salting tissue. However, the fat translocated into intermuscular tissues disappeared during drying process in the salted without BHA tissues whereas in BHA added tissue. This result suggested that BHA may take a role of multiple effect in translocation of fat in tissues as well as in retarding oxidation. In an advanced stage of salted and dehydration, the muscle fibers were ajoined together and then limits between muscle fibers already became indistinguishable. And the migrated fat into intermuscular tissue aggregated around the connective tissue and are apt to gradually to flow out from the muscular system through these tissues.

The purpose of this study was to investigate the effect of work factor/home factor on health status in women office workers. This study investigated the relationship of various influencing factors between health status using claims data of the The Fifth Korean Working Conditions Survey sample from 2017. To this end, we employed logistic regression analysis using sample data from 3,115 female office workers. Logistic regression results indicate that influential factors were ages, employment status, satisfaction with the work environment, sex ratios at workplace, economic burden, childcare burden, housework burden. We discussed several policy and academic implications. As women become more active in society, the number of female workers is increasing. If employers improve the health status of female workers, they will benefit from improved productivity in their business. Therefore, improving the work conditions of the those female workers is very important. Also, practical policy considerations should be needed for female workers to strengthen their social capital in order to enhance their status of health.

We experienced a rare case of sinonasal sarcoidosis initially presenting as nasal cavitary mass. When the clinical course was different from that of typical tuberculosis, physician should think the possibility of sarcoidosis, and re-biopsy or retrospective review of pathological findings might be helpful.

A 5-year-old Pekinese dog was presented for evaluation of a back mass of 1 year duration. Fine needle aspiration cytology of the mass revealed numerous keratinocytes, and a lesser number of multinucleated giant cells along with a low number of spindle cells, which were suggestive of epidermal cyst or hair follicle tumor with secondary granulomatous inflammation. The mass was surgically removed and examined histologically. Microscopically there was partially encapsulated well-demarcated nodule in deep dermis and subcutis. The nodule consisted of central cyst and secondary cysts that were lined by a single or multiple layers of basaloid cells and squamous epitheliums with central laminated keratin. Multifocal aggregation of numerous macrophages and multinucleated giant cells were present. The final diagnosis was keratoacanthoma with granulomatous inflammation. The mass did not recur 5 months after surgery.

Nitrogenous constituents in the extract of 3 species of raw and boiled crabs, tenner crab (Chionoeretes opilio elongatus), horsehair crab (Erimacrus isenbecki), and blue crab (Portunus trituberculatus) caught in the Korean adjacent sea, were analyzed and compared their compositions with the sex and the tissues, body meat, leg meat, and viscera. The crabs contained about 3％ of the extractive nitrogenous constituents in the tissues, meat and viscera. The free amino acid compositions were commonly featured a high content of arginine, taurine, proline, and glycine regardless of the differences in species and tissues. Free amino acids and quarternary bases were greatly increased in hot water extraction while nucleotides were slightly diminished. Glycine betaine and trimethylaminoxide were accounted for above 30% of the total extractive nitrogenous constituents. Arginine, taurine, proline, glycine, glycine betaine, and trimethylaminoxide which abundant in the meats and viscera of the crabs were estimated to greatly contribute directly or indirectly toward appearing the characteristic crabs taste.
