Primary squamous cell carcinoma occuring in the salivary glands involves a grave prognosis since the tumor exhibit infiltrative properties, metastasizes early and recurs readily. But it is so rare that the clinician may see only a few in a lifetime of practice. The following report describes a case of primary squamous cell carcinoma arising from the submaxillary gland treated by combined therapy including surgery, radiotherapy and hyperthermia. The biologic behavior of the tumor was quite abnormal that immediate recurrence was noticed in two weeks after surgery. The progress was dismal and the disease became overwhelming before long.

The growth inhibitory effect of germanium, or soybean sprouts cultured with germanium, on cancer cells was determined in the cultured gastric cancer cell line, AGS. The growth of AGS was significantly inhibited by the addition of 0.01-1％ organic germanium (Ge-132) and germanium stone powder in MTT cytotoxicity assays. The juice from germanium treated soybean sprouts (GTS) inhibited the growth of AGS gastric cancer cells by 78-88％ at concentrations of 2.5 or 5${\mu}\ell$. The juice from Seomoktae GTS revealed an especially higher growth inhibitory effect than that from the control soybean sprouts (germanium non-treated soybean sprouts, GNTS) in AGS. The results suggest that soybean sprouts cultured with germanium may exert an anticancer effect against gastric cancer cells.

Objectives : In order to distinguish morphological characteristics of trunk bark and root bark of Ulmus davidiana var. japonica (Rehder) Nakai and the trunk bark and root bark of Hemiptelea davidii Planchon were sampled and compared in terms of their external and internal features with flour states according to their medical use, through microscopic examination. Methods : The slice of the tested material made by paraffin section technique was colored with Safranine Malachite Green contrast methods, and the flour of it was mounted by the liquid made by the same ratio of each of glycerin, acetic acid, and water, and then observed and photographed by olympus-BHT. Results : 1. Internal Features 1) A large parenchymatous cell was observed in the phloem of the slice of both trunk bark and root bark of Ulmi Cortex. However, both of the trunk bark and root bark of Hemipteleae Cortex did not have parenchymatous cell in the phloem; instead, stone cells including much square crystal of calcium oxalate were distributed around fiber bundle, and the parenchymatous cell included much druse crystal of calcium oxalate. 2) In both the Ulmi Cortex and Hemipteleae Cortex, rhytidome was observed in trunk bark, but not in root bark, but in the parenchymatous cell of the root bark of the Ulmi Cortex contained starch grain. 2. Flour States 1) In the flour of root bark of the Ulmi Cortex, a large parenchymatous cell was observed. However, in the flour of trunk bark and root bark of Hemipteleae Cortex, no parenchymatous eel was found; instead, stone cell including square crystal of calcium oxalate and druse crystal of calcium oxalate were observed. 2) There was no remarkable difference between the trunk bark and root bark of Hemipteleae Cortex. However, starch grain was contained in the parenchymatous cell of the root bark of Ulmi Cortex but not in the trunk bark of it. Conclusions : There were some morphological differences in external, internal, and flour parts of Ulmi Cortex and Hemipteleae Cortex. In particular, there was a morphological difference in flour states between the trunk bark and root bark of Ulmi Cortex, it is possible to use microscope to distinguish their flour states.

Objectives : The root ofCyanchum wifordii(CW) had been used as herbal medicine, 'Baeksuo', in Korea. However, the root ofCynanchum auriculatum(CA) had also been mis-used as 'Baeksuo' in herbal markets, due to its morphological similarity with CW. This study aimed to compare discriminative features and establish the identification-keys between two herbal medicines using microscopic methods.Methods : Microscopic preparations including fixation, rapid dehydration, paraffin infiltration, paraffin embedding, sectioning, mounting, and staining, were performed and the microscopic features between CW and CA samples were compared.Results : The starch grain of parenchymal cells, the amounts of calcium oxalate crystals, cell sizes, and the shape of phloem were not different between CW and CA samples. However, the clusters of stone cells which were conglomerated at outer cortex were apparently observed in CA sample (4~8 layers of stone cells), but not in CW sample (2~4 layers of stone cells, or not). Xylem of CW consisted of several vessels and fiber bundles which were formed as linear shapes and discontinuous radial lines, while that of CA, in which radial lines was not observed, were shaped as a wedge and scattered near cambium with comparatively few fiber bundles enclosed vessels. Especially, in the xylem of CA, fiber bundles located towards cambium were relatively more developed than those located outward cambium.Conclusions : The identification-keys established in this study would be helpful to discriminate microscopic features between CW and CA.

Korean folk medicine 'ORiNaMu' has been used mainly to cure toothache and alcoholism. With regard to the botanical origin of 'ORiNaMu', it has been considered to designate the branch of Alnus species (Betulaceae), but there was no pharmacognostical confirmation on it. To clarify the botanical origin of 'ORiNaMu', the anatomical characteristics of the branch of Alnus firma, A. hirsuta, A. japonica and A. maximowiczii were studied. As a result, it was found the morphological criteria for the four Alnus species that could discriminate them the number of cork cell layer, fiber, stone cell and diameter of vessel. According to there criteria, it was clarified that the commercial folk medicine 'ORiNaMu' was the branch of Alnus firma.

관행재배구의 유기질 비료의 시용이 배 과실 품질에 미치는 영향 1970년대부터 소비자의 선호도가 높은 신고 품종 재배가 급증하기 시작하였고, 2002년 현재 전체 배 재배면적의 70%를 차지하고 있다. 추석이 빠를 경우 성숙이 덜된 과일을 수확하여 시장에 출하함으로서 품질이 좋지 않은 과일로 인하여 소비가 둔화되고 가격이 떨어져 동양배를 재배하고 있는 농가의 수입을 감소시키는 요인으로 작용하고 있다. 따라서 본 실험은 미생물이 들어있는 유기질비료(compost)를 이용하여 추석에 조기 출하되는 신고배의 품질을 향상 시킬 수 있는 방법을 제시하고자 실시하였다. 2년 동안의 compost 처리가 과일에 미치는 영향은 색차계를 이용하여 측정한 결과 Hunter L값과 a값이 높은 경향을 보여 사람의 눈으로 보기에 더 익은 것처럼 보였고, 더 당도가 상승하고 산도가 낮아지는 경향을 보여 과실의 조기성숙이 이루어지고 있다고 판단하였다. 특히, 유기질 비료는 과실내 석세포 함량을 줄였고 칼슘함량을 높여서, 과실의 육질을 부드럽게 개선시킴으로써, 조기 출하되는 과실의 품질을 향상시킬 수 있는 방법으로 제안될 수 있다.

정상 흰쥐 유선상피세포 및 DMBA로 유도안 흰쥐 유선암세포를 in vitro 상태에서 배양시키며 이들의 성장과 증식에 대한 홍삼 사포닌(조사포닌, 총사포닌, Rbl, Rb2, Rc, Rd, Re, Rhl, Rtl2)의 영향을 관찰하였다. 홍삼 사포닌들의 세포 배양중 발생하는 4종의 세포집락의 형태(cobble stone, spindle, honey comb, senescence)에 영향을 미쳤다. 배양한 세포집락에 lucifer yellow용액을 이용하여 SLDT결과 홍삼 사포닌을 첨가하고 배양한 세포군에서 배양 2주째 세포 간극을 통한 세포간 정보전달체계가 양성을 나타내었다. 이것으로 홍삼사포닌이 분화가 덜된 상피 간세포의 분화를 촉진시켜 분화의 지표 중 하나인 세포체포신호전달을 유도한 것으로 사료된다. 그리고 정상 유선 및 유선암 미세절편들을 Matrigel에 배양한 결과 분화의 종 지표인 수종의 다세포구조물이 생성됨을 확인하였는데 정상 조직과 유선암세포로부터 생성된 구조물 ductal, webbed, stellate, squamous colony들of 생성되었는데 유선암세포로부터는 alveloar unit, foamy alveolar nit, squmaous, lobule-ductal, stellate, webbed colony들이 생성되어 다소 상이함을 확인하였다. 그러나 홍삼사포닌을 첨가하여 배양하였을 때 수종의 다세포 구조물 발생 빈도가 변하는 것으로 미루어 보아 홍삼 사포닌이 이들 다세포 구조물의 발생에도 영향을 미치는 것으로 생각된다. 편평상피암의 전암병소라 일컬어지는 편평상피화생의 경우홍삼 사포닌의 존재 하에 이들의 생성이 억제되고 분화가된 ductal colony들의 수가 증가된 것으로 보아 암예방 효과의 기전을 이해하는데 중요한 단서를 제공할 것으로 사료된다.

The tumor in accessory parotid gland (APG) is rarely occurred and its incidence is about 7.7% of all parotid gland neoplasms, but has a higher frequency of malignancy than major salivary glands. The mucoepidermoid carcinoma is the most common malignancy in APG, while B-cell lymphoma is less than 2%. It is often appeared as superficial mass in mid-cheek area. This lesion requires differential diagnosis with epidermoid cyst, lipoma, neurogenic tumors, Stensen's duct stone, lymphadenopathy and hemangioma etc. The mucosa associated lymphoid tissue (MALT) lymphoma, which is also termed extra-nodal marginal zone B-cell lymphoma tends to be localized disease for long time and has a relatively indolent course. We recently encountered a 69-year-old man with superficial solitary mass on the right cheek area that finally diagnosed as MALT lymphoma in APG. We report the rare and unique case with brief literature review.

In cardiovascular disorders, understanding of endothelial cell (EC) function is essential to elucidate the disease mechanism. Although the mouse model has many advantages for in vivo and in vitro research, efficient procedures for the isolation and propagation of primary mouse EC have been problematic. We describe a high yield process for isolation and in vitro culture of primary EC from mouse arteries (aorta, braches of superior mesenteric artery, and cerebral arteries from the circle of Willis). Mouse arteries were carefully dissected without damage under a light microscope, and small pieces of the vessels were transferred on/in a Matrigel matrix enriched with endothelial growth supplement. Primary cells that proliferated in Matrigel were propagated in advanced DMEM with fetal calf serum or platelet-derived serum, EC growth supplement, and heparin. To improve the purity of the cell culture, we applied shearing stress and anti-fibroblast antibody. EC were characterized by a monolayer cobble stone appearance, positive staining with acetylated low density lipoprotein labeled with 1,1'-dioctadecyl-3,3,3',3'-tetramethyl-indocarbocyanine perchlorate, RT-PCR using primers for von-Willebrand factor, and determination of the protein level endothelial nitric oxide synthase. Our simple, efficient method would facilitate in vitro functional investigations of EC from mouse vessels.
