Gastric polyps are morphological diagnoses that collectively refer to various types of lesions, and are commonly found by accident in gastroscopy. Gastric polyps in the broad sense are commonly referred to as abnormal structures protruding toward the gastric lumen, but are generally used only in lesions of the gastric mucosa. The incidence of gastric polyps ranged from 1 to 30% and varied by reporter, and differs by region. Fundic gland polyps were the most common in the West, while hyperplastic polyps were the most common in Korea. Gastric polyps are usually discovered by accident, but because some kinds of polyps have the potential to transform of malignant tumors, histological diagnosis is essential. There should be adequate treatment and management according to the histological results.

Histological observations on the barbels of catfish (Siluridae) in Korea are reported. The mandibular barbel of Far Eastern catfish, Silurus asotus, has epidermis and dermis surrounding an axial rod of cartilage. The stratified epidermis embodies mucous cells, club cells, and taste buds. The mucous cells, which are thin rims of basophilic cytoplasm, and the taste buds, which are basophilic, are located at the surface and the distal portion of the epidermis, respectively. The basement membrane lies between the epidermis and dermis except in places of dermal papillae. The dermis is made up of loose connective tissue fibers enclosing nerve bundles and blood vessels. The central region of cartilage is innermost and enclosed within muscle layers. The mandibular barbel of slender catfish, S. microdorsalis, has an identical structure to those of the Far Eastern catfish however, the percentage thickness of epidermis in the upper and lower parts of the barbel and the number of taste buds in the upper and middle parts of the barbel are different from those of Far Eastern catfish. This study shows that the mandibular barbels in Far Eastern catfish and slender catfish are of a stiff and flexible type.

The chemotherapy sensitive Lewis lung carcinoma (LLC) and chemotherapy resistant Lewis lung carcinoma (CR-LLC) tumors concurrently implanted in mice, and compare these findings with histological macroscopic observations against 3D reconstruction of Fluorescence Molecular Tomography (FMT) preformed in vivo on the same animals. For the 3D image reconstruction we used 32 laser source images, a flat image and 3D surface rendering that confused for 3D Fluorescence Molecular Imaging (FMI). A minimum of ten tissue sections were analyzed per tumor for quantification of the TUNEL-positive cells, cell-associated Cy5.5-Annexin and vessel-associated Alexa Fluor-Lectin. These are useful apoptosis and angiogenesis markers, and they serve as validation experiments to data obtained in vivousing a Cy5.5-Annexin V conjugate injected intravenously in chemotherapy-treated animals carrying the tumors studied histologically. We detected higher levels of apoptosis and corresponding higher levels of Cy5.5 fluorescence in the LLC vs. the CR-LLC tumors according to tissue depth and these findings confirm that in vivo staining with the Cy5.5-Annexing conjugate correlates well with in vitro TUNEL staining and is consistent with the higher apoptotic index expected from the LLC line. There appeared to be 1.38% more apoptosis for LLC than CR-LLC. Consequently there is good correlation between the histology results and in vivo fluorescence-mediated optical imaging. In conclusion the apoptotic images of 3D FMI were validated by microscopic histological image analysis. This is a significant result for the continuous progress of fluorescence 3D imaging research.

Fourier transform infrared spectroscopy(FTIR-ATR) was applied to chemical analysis for conservation status of 10 human bone remains from Joseon Dynasty. The result of crystallinity index (CI) is $4.25{\pm}0.78$, carbonate to carbonate ratio (C/C) is $0.91{\pm}0.04$ and cabonate content (C/P) is $0.19{\pm}0.06$. The higher histological index (HI) confirmed CI and C/P value was increased and C/C value was reduced. While C/C or C/P values analysis is possible. While DNA analysis can be extracted from the bone, C/C values are lower or C/P values are higher was found to the analysis is possible. Chemical assessment of FTIR and histological index consequence is expected to be applicable as a basis for comprehensive understanding of the conservation status excavated bones.

Objectives : The purpose of this study was to investigate the effects of Bee Venom (BV) and Cervi Cornu Parvum pharmacoacupuncture (CC) in monosodium iodide induced arthritis rats. Methods : The subjects were divided into 5 groups ; Normal, Control (no treatment after MIA), BV (Bee Venom pharmacoacupuncture $100{\mu}{\ell}$ daily at Dokbi (ST35) after inducing MIA), CC (Cervi Cornu Parvum pharmacoacupuncture $100{\mu}{\ell}$ dailyat Dokbi (ST35) after inducing MIA) and BV+CC (Bee Venom pharmacoacupuncture and Cervi Cornu Parvum pharmacoacupuncture $100{\mu}{\ell}$daily at Dokbi (ST35) after inducing MIA). After each operation, the present author observed the motor behavior recovery, hematological (Prostaglandin E2, AST, ALT), histological and immunological changes. Rats were tested at the 7th, 14th and 21st day. Results : Results are as follows. 1. All the experimental groups were improved compared with control group in plantar test. 2. All the experimental groups were improved compared with control group in touch test for sensory evaluator. 3. All the experimental groups were significantly decreased compared with control group in prostaglandin E2. 4. In histological observations, knee joint in all the experimental groups were improved compared with control group. 5. In immunological observations, all the experimental groups were significantly decreased compared with control group in COX-1, 2. Conclusions : It can be suggested that Bee venom and Cervi Cornu Parvum pharmacoacupuncture may improve motor behavior, hematological, histological and immunological findings in MIA-induced osetoarthritis rats. Especially, combination of these two treatments will be somewhat better in osteoarthritis recovery and motor function improvement.
