Primary gastric lymphoma (PGL) is derived from mucosa-associated lymphoid tissue (MALT) and it differs from nodal lymphoma in histologic features and biologic behavior. Recent studies have showed that Helicobacter pylori (H.pylori ) infection is closely related to the development of low grade gastric lymphoma, and eradication of the infection induces regression of the tumor. H. pylori infection is known to be important to the development of gastric MALT lymphoma. The aim of this study was to elucidate the histopathological behavior of PGL according to the concept of MALT and to compare the predictive value of tests frequently used for diagnosis of H. pylori. The histological features of gastric lymphoma arising from MALT are the replacement of glands by uniform dense infiltration of centrocyte-like cells in the lamina propria and lymphoidepithelial lesion. H. pylori-associated histologic changes of neutrophilic infiltration, lymphoid follicle or aggregates formation and intestinal metaplasia, and H. pylori immunoreactivity were analyzed. Detection of H. pylori in chronic active gastritis and peptic ulcer suggests a possible role of H. pylori in the pathogenesis. Giemsa, Toluidine blue and Long H&E stains were used in H. pylori detection. Histopathological examination of gastric biopsy specimens revealed lymphoepithelial lesions pathognomonic of MALT lymphoma, and immunohistochemical staining for CD20 was diffusely positive. CD3 was positive in reactive T cells. PAX-5 was negative except the follicle. Bcl-2, cytokeratin, Ki-67, and c-myc were positive. The findings may indicate a predictable transition of low grade to high grade, and c-myc may be used as a valuable marker before molecular pathology diagnosis.

발아시간에 따라 덜 변형된 맥아(60시간 발아)와 적절히 변형된 맥아(96시간 발아)의 총, 불용성 및 수용성 ${\beta}-glucan$ 함량을 측정하였다. 보리의 총 ${\beta}-glucan$ 함량은 3.96%였으며 발아 중에 감소하였는데 덜 변형된 맥아에서는 1.02%인 반면에 적절히 변형된 맥아에서는 0.18%로 급격히 감소하였다. 적절히 변형된 맥아는 $21^{\circ}C$와 $45^{\circ}C$ 추출온도에서 ${\beta}-glucan$ 용해성이 덜 변형된 맥아에 비해 현저하게 증가하였다. 변형정도가 다른 두가지 맥아에 대하여 당화온도별로 당화 후 맥즙과 맥주의 점도를 분석하였다. 당화온도가 $45-75^{\circ}C$로 증가함에 따라 맥즙과 맥주의 점도가 증가하였으며 적절히 변형된 맥아가 덜 변형된 맥아에 비해 점도의 상승이 크지 않았다. 이는 적절히 변형된 맥아는 덜 변형된 맥아에 비해서 당화과정중에 ${\beta}-glucan$ 용해성이 상대적으로 높지만 초기 ${\beta}-glucan$의 함량이 낮을 뿐 만 아니라 맥아에 충분히 합성되어 발달된 ${\beta}-glucanse$의 활성에 의해 당화과정 중에 용출되어지는 ${\beta}-glucan$의 분해가 이루어지기 때문인 것으로 판단되었다.

There were fifty two kinds of fermented soybean sauce before 17th century thirteen recorded in ${\ulcorner}$Sangayorock${\lrcorner}$, two in ${\ulcorner}$Sasichanyo${\lrcorner}$, one in ${\ulcorner}$Yongjechongwha${\lrcorner}$, nine in ${\ulcorner}$Soowonjabbang${\lrcorner}$, one in ${\ulcorner}$Domoondaejak${\lrcorner}$, six in ${\ulcorner}$Dongyoebogam${\lrcorner}$, four in ${\ulcorner}$Gushangchalyo${\lrcorner}$, five in ${\ulcorner}$Guhwangboyubang${\lrcorner}$, two in ${\ulcorner}$Yorock${\lrcorner}$, four in ${\ulcorner}$Chisengyoram${\lrcorner}$ and five in ${\ulcorner}$Joobangmoon${\lrcorner}$. These books had thing to know when making fermented soybean sauce like kinds of soybean sauce, how to make it, its ingredients and quantities to be used, how to make fermented soybean sauce in haste, and how to remake wrong made fermented soybean sauce, etc. Before 17th century, fermented soybean malt was divided into two kinds the only soybean malt and the mixed soybean malt that had bean, wheat, wheat flour and wheat bran. The bean only soybean malt was further divided into mashed soybean malt (Beans were steamed and mashed into past.) and unmashed soybean malt (Beans maintained their shape without being mashed.) while mashed soybean malts were made in Winger, in January of February, unmashed and mixed soybean malts were made in Summer, in July. When made fermented soybean sauce, mashed and unmashed soybean malts were used as they were and mixed soybean malt was dried and powdered for use. Fermented soybean sauce before 17th century could be classified by the features of soybean malts being used, Normal fermented soybean sauce was made from bean only soybean malts and other ingredients. Shi(시) was made from unmashed soybean malts, in which beans maintained their shape, and Gowhajang and Jeupjang were made from mixed soybean and wheat bran. Fermented soybean sauce was also made from old fermented soybean sauce, yeast. water leftover after boiling bean leaves, and soybean chaff without soybean malt. There were also side dish type soybean sauce like Kongjaban today and fish and meat sauce made from flesh ingredients. To make fermented soybean sauce in haste, the soybean sauce was heated. Beside there were how to maintain fermented soybean sauce and how to remake wrong made fermented soybean sauce.

This study investigated the effect of kilning condfition on the diastatic power and activities of protease, $\alpha$-amylase, and $\beta$-amylase in rice malt. Common rice (Oryza sativa) was steeped at $30^{\circ}C$ for 50 h, germinated at $30^{\circ}C$ for 7 days, and kilned at $50^{\circ}C$ for 24 h. The moisture content and enzymatic activities were determined under various kilning times. As a result, the moisture content was reduced from 42.1 % to 3.9% after 24 h of kilning at $50^{\circ}C$. The protease activity of rice malt showed lower value than that of barley malt. All enzymatic activities were decreased during the kilning stage. Results indicated that after prolonged kilning at $50^{\circ}C$, the inactivation of hydrolytic enzymes might be occurred. Even though the amylolytic activity of malted rice showed low value, the rice malt shows the potential characteristics as ingredient for the brewing and cereal industries.

Out of all oral malignant tumor, malignant lymphoma occurs in only 3.5%. Especially, most of the primary malignant lymphomas, which occur in the head & neck region are high-grade diffuse large B-cell lymphoma and mucosa-associated lymphoid tissue (MALT) marginal zone B-cell lymphoma is very rare. In the head & neck region, malignant lymphoma is reported to occur in the thyroid, salivary gland, trachea, larynx, orbital lobe and the Waldeyer's ring. Among the Waldeyer's ring, palatal tonsil is reported to be the most common region, but, only 1 case report was published in Korea. Until now, there were no case reports of MALT lymphoma that occurred in the tongue. The purpose of this case report is to report and discuss on a case of MALT lymphoma of the tongue.

Papillary thyroid carcinoma (PTC) is the most prevalent type of thyroid cancer. In contrast, thyroid lymphoma is a very rare disease. Concurrent onset of both is very rare in the thyroid gland. Ultrasound (US)-guided Fine needle aspiration (FNA) is a useful diagnostic tool, but occasionally pathology results may change after the surgery. A 56 years old woman visited with Hashimoto's thyroiditis and nodule on the thyroid gland isthmus on US exam. US-guided FNA was performed at thyroid nodule and diagnosed as PTC. The patient underwent total thyroidectomy. The pathological findings revealed a mucosa associated lymphoid tissue (MALT) lymphoma accompanied with PTC. Authors report this unusual case with a review of literature.

Extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) is a low-grade B-cell lymphoma that typically follows an indolent clinical course. It occurs in a variety of mucosal linings extranodal tissue, most commonly in the stomach. Other commonly involved sites include other parts of the gastrointestinal tract, thyroid, salivary gland, lung, lacrimal gland, synovium, dura mater, breast, skin, and eyes. It occurs very rarely in the buccal mucosa. A 50-year-old man came to the clinic while presenting a 5-month history of right-sided buccal mass. The incisional biopsy did not confirm the diagnosis of the lesion. He underwent complete excision of buccal mass for the diagnosis and treatment. The final pathology confirmed MALT lymphoma immunohistochemically. After surgery, he received radiotherapy with 30.6 Gy. There is no recurrence for 8 months after treatment. Herein we report a rare case of buccal MALT lymphoma with a review of the literature.

Purpose: Lymphoma originated from mucosa associated lymphoid tissue(MALT) is most common in gastrointestinal system, and rarely found in salivary gland, thyroid, bronchus or orbit. We experienced a case of MALT lymphoma which was originated from conjunctiva and involving lower eyelid without metastasis. Methods: A 40-year-old man suffered palpable mass on right lower eyelid without pain. Orbital computed tomographic and ultrasonographic findings showed a conical mass($1.9{\times}1.2{\times}0.9cm$ size) inside lower eyelid. The mass was completely excised under local anesthesia and histopathological examination was followed. Results: Microscopic finding showed a multiple follicular colonization. In the follicle, small lymphocytes and plasma cells differentiated to centrocyte-like cell, monocyte B cell, plasma cell were diffusely infiltrated. Immunophenotyping was preformed on fixed section. The majority of the small cells were immunoreactive for the B cell marker CD20. Based on the typical histological findings supported by immunostaining, the mass was defined as MALT lymphoma. After excision, SPECT, abdominal CT was carried out and there were no evidence of extraorbital disease. Conclusion: Biopsy and pathological examination should be performed in patients who complain palpable mass on lower eyelid because of possibility of MALT lymphoma. Although MALT lymphoma is rarely metastasized, it is necessary to evaluate the extraorbital involvement using SPECT or other radiologic exams. For detecting extraorbital involvement, periodic follow-up examination is need.
