Objectives : This study was carried out to investigate the effect of Samooltang (SMT) on the injury of gastric mucous membrane by ethanol in mice. Methods : The normal group was mice with no inflammation. The control group was mice with gastro-inflammation elicited by ethanol. The sample group was SMT-administered mice before gastro-inflammation elicitation. Results : In the immunohistochemical change, the distribution of SBA and COX-1 treated with SMT noticeably increased over the control group (p<0.05). The distribution of NF-κB P50, COX-2, and TUNEL treated with SMT noticeably decreased over the control group (p<0.05). The distribution of SMT was the same as the normal group. Conclusions : According to the above results, it is supposed that SMT would be helpful against gastritis and gastric ulcer caused by alcoholic drinks.

The skin structure of Misgurnus mizolepis was studied based on the microanatomical investigation of skin fragments taken from four regions. The epidermis was distinguished by two types of skin glands, a small mucous cell and a large club cell. The mucous cell was acid sulfomucins (some sialomucins) but the club cell did not give any histochemical tests for mucosubstances. The presence of a well defined lymphatic system with small lymphocytes was established in the stratum germinativum layer of the epidermis. A large number of blood capillaries run very close to each other just below the basement membrane, and a definite area giving AB and PAS positive was present between the basement membrane and scale. These structural features of skin in M. mizolepis seem to be closely related with cutaneous respiration.

The ultrastructure of the gills of Oplegnathus fasciatus was examined by means of light and transmission electron microscopes. The gills have primary and secondary filaments (lamellae). The following cells are identified and described : epithelial cell, pillar cell, chloride cell and mucose cell. The simple epithelial layer consists of squamous epithelium containing a large nucleus and the surface is covered with some of microridges. The lamella pillar structures are characterized by axial microtubules and lateral membrane interdigitations. Chloride cells contain a lot of mitochondria and specifically developed tubular systems. The rough endoplasimic reticulum and golgi complex, and some of mucous granules were observed in immature mucous cells. The mature mucous cells were AB-PAS positive, globular in shape, and had mucous granules of similar size with various electron densities.

This study was carried out to investigate the effect of Keuibi-tang (KBT) on the injury of gastric mucous membrane by stress and ethanol in mice. The normal group was non-inflammation elicited mice. The two control groups were mice with gastro-inflammation elicited by stress and ethanol. The two sample groups were mice administered KBT before gastro-inflammation elicitation. In the common morphology and histochemical change, the two control groups were observed with various injuries such as hemorrhagic erosion and ulcer, while the sample group was the same as the normal group. In the immunohistochemical change, the distributions of PNA and COX-1 treated with KBT noticeably increased over the control group (P<0.05). The distributions of $NF-{\kappa}B$ p50, COX-2 and TUNEL in the group treated with KBT were noticeably lower than in the control group (P<0.05). The distribution of KBT was the same as the normal group. According to the above results, it is supposed that KBT is applicable to gastritis and gastric ulcer due to stress and alcoholic drinks.

Objectives This study was designed to investigate the effects of fermented soybean upon anti-inflammation, cytotoxicity, antioxidant and intestinal mucous membrane permeability by measuring the cell viability, NO (nitric oxide) production, DPPH, Polyphenol, HRP and TEER in cells like Raw 264.7 and HCT 116 using fermented soybean. Methods Raw 264.7 cell and HCT 166 cell were used in this study. And fermented soybean powders were used for the experimental group and soybean powders for the control group. There was inflammation response upon using lipopolysaccharide(LPS). Fermented soybean powders and soybean powders were in a respectively different dose added to the cells with LPS. MTT assay, NO, DPPH and Polyphenol measurement, TEER, HRP were conducted for each cell. The results of this study were presented in mean and standard deviation. Results 1. In Raw 254.7 cells added with $100{\mu}l/ml$ unfermented soybean powders, 104.95% higher than 62.59% was measured. In Raw 254.7 cells added with $100{\mu}l/ml$ fermented soybean powders, there was 74.90% measured higher than 62.59%, which was a significant result. 2. By a gradual increase of unfermented soybean powders like $0.1{\mu}l/ml$, $1.0{\mu}l/ml$, $10{\mu}l/ml$, $100{\mu}l/ml$, the measured NO were also gradually decreased $53.12{\mu}M$, $47.57{\mu}M$, $37.02{\mu}M$, $28.16{\mu}M$. In case of cells added with fermented soybean powders, $43.95{\mu}M$ NO was measured in $0.1{\mu}l/ml$ which is significant, and in other cases, mostly measured over$ 56.72{\mu}M$. 3. It was inferred that fermented soybean powders have anti-inflammatory effects of maintaining intestinal mucous membrane permeability because the measured values of cells in both groups were all higher than $133.62{\Omega}$ measured of cells added with only LPS. And measured values of cells in both groups were all lower than 2.26 measured of cells added with only LPS. 4. In case of experiment DPPH and polyphenol measurement, fermented group was all higher than unfermented group. Conclusion From the results of conducting MTT assay, NO measurement, and TEER, HRP by using cells Raw 264.7 and HCT-116, even though there was no significance in the correlation between cytotoxicity, anti-inflammatory effects, both unfermented soybean powders and fermented soybean powders were shown to have intestinal mucous membrane permeability improvement effects. This effects could be applicable for autoimmune diseases, chronic inflammatory diseases and so additional studies are expected in the future. From the results of conducting DPPH, Polyphenol measurement, Fermented soybean may be useful as potential antioxidant.

The ultrastructure of submandibular gland was examined in the Korean spider shrew, Sorex caecutiens. The submandibular gland wat composed of acini and salivary ducts. A submadibular acinus was a mixed gland having serous demilune cells and mucous cells that were filled with well developed rER, mitochondria and large amount of dense secretory granules. Serous acinar granules were oval shape without distinct limiting membrane on the border and it had only coarse specks with various density. Mucous acinar granules were oval shape without distinct limiting membrane and had a variety pattern with several thin or transparent bands into the homogeneous dense matrix. Thus submandibular acinar granules of S. caecutiens belonging to subfamily Soricinae were distinct from the other mammalian species including Crocidurinae, because of the absence of limiting membrane of acinar granules and specific pattern of mucous acinar granules. Granular duct cells had large amount of small granular vesicles and several characteristic structures of granule which were revered with stratified limiting membranes and filled with coarse serous-like granule or homogeneous matrix.

The structure of skin of a mud loach Misgurnus anguillicaudatus was described in relation with their histochemical nature from four regions of the skin. The epidermis has a strongly thick layer of two glandular cells, consisting of a elongate mucous cell and club cell, and a thin layer of superficial layer. The secretion of the elongated mucous cell was acid mucopolysaccharides in nature but the club cell did not give any histochemical reaction. A well defined lymphatic system, comprising small lymphocytes was present in the stratum germinativum layer of the epidermis. A pit organ of a pear-shaped structure was present below the epithelial cells and lie directly on the basement membrane. The organ has blood vessels serving the sense organs of the epidermis. There was a definite area showing acid mucopolysaccharides in the stratum laxum layer of the dermis. Small scales are present deep in the dermis except the top of the head. A great number of blood capillaries were found just under basement membrane. These structural features of skin in M. anguillicaudatus seem to be closely related with cutaneous respiration using air.

Desquamative gingivitis (DG) is a gingival manifestation of systemic mucocutaneous disorders such as mucous membrane pemphigoid, oral lichen planus, and pemphigus vulgaris. The lesion is very painful, so affects the patient's ability to do proper oral hygiene practices. This may be a potential risk factor for long-term periodontal health. However, there is some controversy about the relationship between the existence of DG and periodontal status. Although the correlation between DG-associated diseases and periodontal status is not to be certain, early diagnosis and appropriate treatment including adequate plaque control and removal of local factors is very important for preventing the progression of diseases and destruction of periodontal tissues.
