The study was conducted to evaluate the effects of carboxymethyl chitosan (CMC) on proliferation, migration, and lipopolysaccharide (LPS)-induced inflammatory response in canine bone marrow-derived mesenchymal stem cells (BMSCs). The proliferation and migration of BMSCs were examined after treatment with CMC. The effect of CMC on the mRNA expression of inflammatory cytokines, such as interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, IL-10, and transforming growth factor (TGF)-β, was also evaluated by reverse transcription polymerase chain reaction (RT-PCR). In the proliferation assay, no significant changes were found at all CMC concentrations compared with controls. The migration assay showed that CMC dose-dependently stimulated the migration of BMSCs in normal and LPS-treated conditions. RT-PCR showed that TNF-α and IL-10 expressions were suppressed in the BMSCs after CMC treatment. However, other genes were not affected. Taken together, CMC promoted BMSC migration and inhibited TNF-α and IL-10. Therefore, CMC may be possible to regulate wound healing when mesenchymal stem cells are applied in inflammatory diseases.

Purpose: Scutellaria baicalensis is a herb which has effect of eliminating heat, drying dampness, purging away fire, detoxicating. Clinically, has been used to remove fever and control of inflammation. We have studied in series to investigate the effective traditional oriental medicines of treatment for endometriosis. In this study, the effects of Scutellaria baicalensis administrated orally or rectally on surgically induced endometriosis in rat were investigated. Methods: The endometrial tissues of rats were autografted to their small intestine. Rats with surgically induced endometriosis were administered with Scutellaria baicalensis extracts for 40 days orally or rectally. We observed the tissue size of ectopic uterine implants at the mesenteric with the naked eye and examined the concentration of estradiol, progesterone, $TNF-{\alpha}$ and IL-2, IL-4, IL-6 and IL-10 in serum. Also, we inquired which was more effective between oral administration groups and rectal administration groups. Results: The size of ectopic uterine implants of orally or rectally treated groups was much smaller than those of control groups. The concentrations of estradiol, progesterone, $TNF-{\alpha}$, IL-2 and IL-6 were significantly decreased in oral administration experimental group compared with the control group. The concentrations of progesteron, $TNF-{\alpha}$, IL-2 and IL-6 were significantly decreased in rectal administration experimental group compared with the control group. The efficiency of oral administration group was better than that of rectal administration group at the serum concentration of estradiol and IL-4. Conclusion: Our data suggest that Scutellaria baicalensis inhibit the inflammation induced from ectopic uterine implants at the mesenteric wall and inhibit the growth of ectopic uterine implants. Judging from the above results, it can be suggested that Scutellaria. baicalensis should be a useful agent for inhibiting the inflammation induced from ectopic uterine implants and the proliferation of endometriosis. Maybe, oral administration of Scutellaria baicalensis is more effective than rectal administration.

Objectives: To report a correlation of IL-6 of pancreatic cancer and cancer progression in three pancreatic cancer patients. Method: Three pancreatic cancer patients were monitored for changes in IL-6 levels, tumor markers (CEA, CA19-9), and clinical outcomes over their treatment period. Results: Patient 1's IL-6 levels rose with liver metastasis and tumor progression, coinciding with increases in tumor markers. Patient 2's IL-6 levels remained elevated during chemotherapy, correlating with tumor growth. Patient 3's IL-6 levels spiked prior to cancer progression. Conclusion: Elevated IL-6 levels were observed in advancing pancreatic cancer patients, suggesting IL-6 as a potential biomarker for monitoring cancer progression in pancreatic cancer. Regular IL-6 monitoring could improve prognostic evaluations and treatment strategies.

The relation of endocrine in the western medicine and zangfu-organ functions in Korean medicine, related to growth disturbance, was studied and derived the following results. 1. The hormone most related to growth disturbance is, directly secreted from the anterior pituitary or is stimulated and secreted in the target grands, growth hormone, thyroid, adrenocortical hormone, gonadial hormone and is insulin secreted from $\beta$ cell of langerhans' slands of pancreas. 2. the pituitary has the most close relation with the kidney in the five zang-organ. Because the kidney is innate origin(先天之本) and promotes qi and blood(生化氣血), stores the essence of life(藏精), dominates the bones(主骨) and promotes the marrow(生骨髓). Especially it is connected with brain(通於腦). 3. In the children growth, the endocrine action in the pituitary has the most close relation with the kidney, As in the reports of the brain and spinal cord, bone, store essence of life, sexual maturation and decline(kidney-qi, sexual functions of both sexes(天癸)) etc, and cause of cretinism, dwarf in the main subject. 4. Somatomedin is the most important factor of the growth factors, IGF in another word. The unification of IGF and secretion is controlled firstly according to growth hormone, however is very closely related to the nutrition status in the non-hormonic causes. Also, it is affected very much by the insulin. 5. Insulin is one of the important hormone related to the growth and is secreted from the pancreas. Pancreas belongs to the functional system of spleen in oriental medicine, thus the growth disturbance, occurred due to error in insulin secretion and nutrition(in another words, the lack of postnatal essential substance from food-stuff(水穀精氣)), is closely related to the spleen. 6. From the results driven above, the hormone action of endocrine and problem in secretion, related to the growth disturbance, must be focused on the differentiation of symptoms and signs of the kidney and the spleen in oriental medicine.

Kimchi cabbage is one of the most important vegetables in Korea and a target crop for market stabilization as well. In particular Kimchi cabbages in a highland area are very sensitive to the fluctuations in supply and demand. Yield variability due to growth conditions dictates the market fluctuations of Kimchi cabbage price. This study was carried out to understand the distribution of the highland Kimchi cabbage growth status in Anbandeok. Anbandeok area in Gangneung, Gangwon-do, Korea is one of the main producing districts of highland Kimchi cabbage. The highland Kimchi cabbage status map of each growth factor was obtained from unmanned aerial vehicle (UAV) imagery and field survey data. Six status maps include UAVRGB image map, normalized difference vegetation index (NDVI) distribution/anomaly map, Crop distribution map, Planting/Harvest distribution map, Growth parameter map and Growth disorder map. As a result, the highland Kimchi cabbage status maps from May 31 to Sep. 6 in 2016 were presented to show spatial variability in the field. The benefits of the highland Kimchi cabbage status map can be summarized as follows: crop growth monitoring, reference for field observations and survey, the relative comparison of the growth condition in field scale, evaluation of growth in comparison of average year, change detection of annual crops or planting areas, abandoned fields monitoring, prediction of harvest season etc.

The effective growth of pepper seedlings relies on the growing period and tray used, which both aim to minimize seedling damage during the transplantation process. Therefore, the objective of this study was to evaluate the effect of red and green pepper seedling growth in plug and cylindrical paper pot (CPP) trays with different growth periods of the seedlings. Two different seedling growth trays were used for the two varieties of pepper seedlings in the same growing media. The pepper seedling growth rates were investigated at 15, 30, and 45 days for each of variety. Important parameters, e.g., the plant height, fresh weight for the plant and root, number of leaves, leaf length and width, and leaf chlorophyll contents, were measured. During the experiment, the CPP tray maintained uniform seedling growth as compared to the plug tray. CPP trays ensured the height of the seedling, with these results 0.84 to 1.6 times higher than those of the plug tray for all conditions, indicating the good quality of the pepper seedlings. The shoot and root weights were found to be greater with more leaves in the CPP tray seedlings for 45 days compared to the seedlings grown in the plug tray, whereas the green pepper variety showed a greater leaf ratio than the red pepper seedlings. The analysis of pepper seedling growth presented in this study will guide the selection of suitable growth trays and seedling periods for farmers when they undertake automatic pepper transplantation in the field.
