  • Glycogen-rich clear ceil carcinoma of the breast is an unusual variant of carcinoma with a recorded incidence of $1.4{\sim}3%$ of breast carcinomas. The cytologic characteristics have not been well described. We report two cases of glycogen-rich clear cell carcinoma with corresponding fine needle aspiration(FNA) cytologic findings and compare them to infiltrating ductal carcinoma and other clear ceil malignancies with a review of literature. One was a 62-year-old woman exhibiting a palpable mass of the right breast. The smears showed atypical tight cell clusters and individually scattered single cells containing leanly or clear abundant cytoplasm with well defined cytoplasmic margins. Mild to moderate nuclear pleomorphism and a prominent nucleolus were present. The other was a 42-year-old woman who was admitted with a right breast mass. The smears showed moderately cellular, tightly cohesive tumor cells. The cytoplasmic outline was generally well demarcated. The tumor cells Contained foamy to clear abundant cytoplasm with large and small vacuoles. The nuclear pleomorphism was marked. Both tumors resected by modified radical mastectomy, were diagnosed as glycogen-rich clear cell carcinoma. Histologically, the clear cell nature of tumor cells were not characteristic enough to predict this type of the tumor. Some cytologic features can be distinguished other clear cell breast cancer from glycogen-rich carcinoma. Recognition of these unusual patterns in a breast FNAC should raise the suspicion of a clear cell carcinoma including glycogen-rich subtype. Cytological localization of glycogen using PAS and D-PAS staining may permit the correct Identification and differential diagnosis of this tumor.

  • The concept of latent-gi(伏氣) was first mentioned in Yellow Emperor's Canon of Internal Medicine. For example, Elementary Questions states, "Damage by cold in winter necessarily engenders warm disease in the spring." Zhang Zhong-Jing of Han Dynasty in On Cold Damage and Miscellaneous Diseases mentions warm disease, stating, for example, "Greater yang disease with heat effusion and cough and without aversion to cold is warm disease. If sweating is applied, and there is generalized heat, this is wind warmth." However, the concept of warm disease was not central to his systematic presentation of externally contracted disease which placed the emphasis on wind and cold as the major causes of these diseases. Zhang Zhong-Jing's theories centuries after in the Sung Dynasty were to become the focus of the cold damage school, whereas the concept of warm disease was to become the focus of a rival school, the warm disease school. In the Sui-Tang Period, The Origin and Indications of Disease mentions warm diseases, their causes, patterns, and major principles of treatment. Successive generations of doctors wrote about warm disease, and in the Ming Dynasty writings on the subject become more prolific. This development is attributable on the one hand to the opening up of the south of China where febrile diseases tended to be of a different nature than in the north, and on the other to pestilences arising as a result of wars. In this period, Wu You-Xing in On Warm Epidemics explained in detail the laws governing the origin, development and pattern identification of warm epidemics. Notably, he posed the etiological notion of a contagious perverse gi.

  • Objectives : This study examined the possibility of therapeutic application of natural pigments in the Joseon Period other than aesthetic purposes. Methods : The medicinal properties of natural pigments as written in the texts Sangayorok, Gyuhapchongseo, Imwongyeongjeji were searched and analyzed in the texts Bencaogangmu, Encyclopedia of Eastern Medicine, and the Encyclopedia of Chinese Medicinals focusing on their Qi, flavor, effects and application. Of the conditions they treated, we examined whether they treated skin conditions using external application. The Korean Medical effects of these pigments were examined based on the content of the skin chapter of the Donguibogam. Results : We were able to extract 47 kinds of natural pigments, most of which had cold nature and bitter tasting properties. In addition, most of the pigments had the effect of treating skin conditions, illnesses due to micro-organisms, and of detoxifying. Conclusions : After consideration of medicinal properties and effects of the herbs that were used as pigments in the Joseon period, it could be concluded that as these herbs not only function as pigments but also hold properties that prevent skin conditions, their therapeutic functions could have been considered when using them as pigments.

  • Mistletoe (Viscum album) is a common name for many species of semi-parasitic plants which grow on deciduous trees all over the world. In this study, the immunomodulatory activity of the water-extract of Korean mistletoe fruits (KMFWE), was investigated on murine peritoneal macrophages. The culture supernatants of KMF-WE-stimulated murine peritoneal macrophages showed the increased production of IFN-$\gamma$, IL-$1{\beta}$ and TNF-$\alpha$, in a dose-dependent manner. KMF-WE also induced chemokine production from murine peritoneal macrophages such as RANTES, MCP-1, MIP-$1{\alpha}$ and MIP-$1{\beta}$, as well as nitric oxide (NO) production, in a dose-dependent manner. The gel filtration fraction revealed F-1, which is the early-eluted and high molecular weight product, is the major fraction of KMF-WE to activate the murine peritoneal macrophage to induce cytokines, chemokines and NO. The nature of F-1 fraction needs to be examined in detail in further studies to define the regulatory mechanisms of cytokine or chemokine induction by KMF-WE on macrophages. These results suggest that KMF-WE possess a potent immunostimulant activity and can be a promising candidate available for development of immunomodulators.

  • Prospect Hill Virus (PHV) is the well known serotype of hantavirus, a newly established genus in family Bunyaviridae. Extensive studies have upheld the original view of PHV genetics with three genes such as nucleocapsid (N) protein, envelope proteins (G1, G2) and RNA dependent RNA polymerase. In this study, we report the existence of additional gene that is encoded in an overlapping reading frame of the N protein gene within S genome segment of PHV. This gene is expected to encode a nonstructural small (NSs) protein and it seems to be only found in PHV infected cell. The presence and synthesis of NSs protein could be demonstrated in the cell infected with PHV using anti-peptide sera specific to the predicted amino acid sequence deduced from the second open reading frame. Ribosomal synthesis of this protein appears to occur at AUG codon at the 83rd base of S genome segment, downstream of N protein initiation codon. This protein is small in size (10.4 KDa) and highly basic in nature. The expression strategy of NSs protein appears that a signal mRNA is used to translate both N and NSs protein in PHV infected cell. 10 KDa protein in virus infected cell lysates can bind to mimic dsRNA. This fact strongly suggests that NSs protein may be involved in virus replication on late phase of viral life cycle.

  • Purpose: Elastofibroma is a rare benign tumor that is characterized histologically by the presence of abnormal elastic fibers within a stroma of fibroadipose tissue. Usually it is slow-growing, solid, ill-defined mass occurring chiefly in elderly woman and arising from the soft tissue around the inferior angle of the scapula. Methods: We experienced a representative case of elastofibroma. A 73-year-old women complained of a soft-tissue mass, which measured $6{\times}6cm$, at the inferior angle of the left scapula, which had been found incidentally 4 months before. When the arm was elevated, the mass projected out beneath the scapula. The entire mass was resected with a tumor-free margin. Results: The resected tumor appeared to be nonencapsulated, fibrous and white mass, and it contained yellow fatty streaks. We confirmed that the histopathologic diagnosis of this tumor was elastofibroma. Follow-up examination revealed no evidence of local recurrence for 10 months. Conclusion: This entity is rarely reported in Korea. However, more patients could be diagnosed if physicians pay more careful attention to clinical and radiological features of elastofibroma. Moreover, recognizing the benign nature of this lesion is important to avoid an unnecessary operation.

  • The fire not to back to its origin(火不歸原) is said that source yang(元陽) of sea of qi(氣海) rises because fire(火) of lower energizer(下焦) can't return to its origin. Successive medical men regarded the cause of it as yang deficiency(陽虛) or yin deficiency(陰虛) generally, but Jangseoksun(張錫純) presented eight kinds of cause, they are syndrome of upcast yang(戴陽證), deficiency of qi(氣虛), yin deficiency, yin and yang deficiency(陰陽虛), thoroughfare qi ascending counterflow(衝氣上衝), heart fire(心火), yang deficiency with cold fluid retention(寒飮) in middle energizer(中焦寒飮), yang deficiency with sunken cold locked in(沈寒錮冷). The method of conducting fire back to its origin may be the treatment of fire not to back to its origin as an interpretation of the phrase in a broad sense, but it is limited to yang deficiency with sunken cold locked in besides syndrome of upcast yang as the treatment based on pathological conditions. By this standpoint Eunsuryong(殷壽龍) used conducting fire back to its origin to remove hidden cold(伏寒) and make rising false fire(假火) settle. The meaning of conducting fire back to its origin is not just raise yang qi(陽氣) but break sunken cold locked in by using the drugs like Buja(附子), Yukgye(肉桂). Jakyak(芍藥) can concentrate yang qi on the life gate(命門) by converging it, Sukjihwang(熟地黃) can supply yin essence(陰精) and check the intense nature of tonifing yang(補陽) drugs. So if we want to use the method of conducting fire back to its origin, we should confirm the symptoms of sunken cold locked in and yang deficiency not to misdiagnose yin deficiency.

  • In order to compare the nocturnal penile erection and the erection induced by intracavernosal injection of papaverine, digital palpation of penis, erectile angle, and the rigigram using $Rigiscan^{(R)}$ were evaluated in 38 erectile dysfunction patients(13 psychogenic, 18 vasculogenic, 1 neurogenic, 3 vasculo-neurcgenic, and 3 undetermined). The following results were obtained. 1. Among the 32 patients of the nocturnal penile erection > 40% on rigigram, only 15 patients(46.9 %) demonstrated rigidity > 4+, a sufficient rigidity for sexual intercourse, on papaverine test. 2. The maximal degree of rigidity was also measured by the erectile angle of the penis. Among the 32 patients of nocturnal penile erection > 40% on rigigram, 23 patients(71.9%) had an angle > $45^{\circ}$. 3. Sixteen patients(42.1%) demonstrated similar increase in the maximal circumferential expansion of the distal portion of the penis on nocturnal penile erection and papaverine-induced erection. Nineteen patients showed larger circumferential expansion on nocturnal penile erection than on papaverine-induced erection. Fifteen patients showed similar circumferential increase of the basal portion of the penis on nocturnal penile erection and artificial erection, while 12 patients(31.6 %) showed larger circumferential increase on artificial erection than on nocturnal penile erection. 4. In the 15 patients of nocturnal penile erection > 40 % on rigigram and > 4+ on papaverine test, the duration of maintenance of the maximum erection on nocturnal penile erection and artificial erection proved to be not proportional. Thus, the arthficial erection induced by papaverine and the nocturnal penile erection can not to be said to be of same in nature and therefore, in order to make more definite diagnosis, both tests should be done and compared.

  • The clinical staging systems for oral squamous cell carcinoma is limited as a prognostic indicatior because of different biological characteristics of cancer in this region and variable microenvironment depending on subsites, there have been study to determine prognosis by evaluating malignancy, that is the nature of tumor cells. Many studies have been tried to determine prognostic indicator in various malignancies for the evaluation of differentiation capacity and the expression of oncogene product. EGF make a role in cellular growth and differentiation and to be essential in cellular survival. EGFR is an intergral membrane protein, stimulate cellular differentiation and hormonal secretion, and has structural homology with V-erb-B transforming protein. Recent reports have demonstrated that EGFR is overexpressed in stomach, breast, vagina, dermis, head and neck, genitourinary and lung tumors, and possibly used as a tumor marker. In head and neck region, most of studies were mainly carried out on laryngeal squamous cell carcinoma. In the present study, immunohistochemical study for EGFR and C-erb-B2 gene in paraffin sections of 45 squamous cell carcinoma in oral cavity was performed to evaluate the presense of EGFR and C- erb-B2 gene in this lesion, to evaluate them as a prognostic indicator by analysing the correlation between these expression and subsites, primary stages, clinical stages, pathologic grades, neck node metastasis, recurrences and treatment results, and to determine relation between EGFR and C-erb-B2 gene.
