The objective of the present studies was to develop and validate a system for isolation, purification and extended culture of pigment-producing cells in alpaca skin (melanocytes) responsible for coat color and to determine the effect of alpha melanocyte stimulating hormone treatment on mRNA expression for the melanocortin 1 receptor, a key gene involved in coat color regulation in other species. Skin punch biopsies were harvested from the dorsal region of 1-3 yr old alpacas and three different enzyme digestion methods were evaluated for effects on yield of viable cells and attachment in vitro. Greatest cell yields and attachment were obtained following dispersion with dispase II relative to trypsin and trypsin-EDTA treatment. Culture of cells in medium supplemented with basic fibroblast growth factor, bovine pituitary extract, hydrocortisone, insulin, 12-O-tetradecanolphorbol-13-acetate and cholera toxin yielded highly pure populations of melanocytes by passage 3 as confirmed by detection of tyrosinase activity and immunocytochemical localization of melanocyte markers including tyrosinase, S-100 and micropthalmia-associated transcription factor. Abundance of mRNA for tyrosinase, a key enzyme in melanocyte pigment production, was maintained through 10 passages showing preservation of melanocyte phenotypic characteristics with extended culture. To determine hormonal responsiveness of cultured melanocytes and investigate regulation of melanocortin 1 receptor expression, cultured melanocytes were treated with increasing concentrations of ${\alpha}$-melanocyte stimulating hormone. Treatment with ${\alpha}$-melanocyte stimulating hormone increased melanocortin receptor 1 mRNA in a dose dependent fashion. The results demonstrated culture of pure populations of alpaca melanocytes to 10 passages and illustrate the potential utility of such cells for studies of intrinsic and extrinsic regulation of genes controlling pigmentation and coat color in fiber-producing species.

The major symptoms of terminally ill cancer patients are fatigue, loss of energy, feeling of helplessness, poor appetite and pain as well as general weakness, which are very similar to symptoms of adrenal insufficiency. Adrenal insufficiency-induced symptoms widely vary from mild symptoms to life-threatening conditions and may be resulted from variable medical causes. For terminally ill cancer patients who are hospitalized for palliative care, opioid agents are prescribed to control moderate to severe pain. The use of acute or chronic opioid agents is believed to negatively affect adrenal gland function. In most studies of opioid effects (preclinical/clinical with animal subjects or and patients suffering non-malignant pain, adrenal insufficiency and hormonal abnormalities were observed as side effects. However, opioid-induced adrenal insufficiency has been rarely reported in studies with patients with malignant cancer pain. Relationship between the type, treatment period, dosage of opioid agents and hormonal abnormalities can be examined by measuring the functional level of the adrenal glands. We hope to improve patient's quality of life by indicating hormone substitution to treat symptoms of adrenal insufficiency.
Objective : The purpose of this report was to provide the information about activity and safety of Ojeok-san by analyzing domestic/international papers about Ojeok-san. Methods : Domestic/international papers related to Ojeok-san were reviewed and analyzed. These papers were then classified by year, experimental method and subject. Results : The following results were obtained in this study. 1. The studies of Ojeok-san started from 1984 and has continuously increased. The studies were mainly focused on experimental models rather than clinical studies. 2. By subject, papers related to safety were most common with 5 papers among 20 papers. Besides there were papers related to efficacy of analgesic, anti-hyperlipidemic, anti-blood stasis and treatment for uterine myoma. 3. The papers related to safety were mainly focused on the effect of Okeok-san on liver function, renal function or metal concentration of organs such as blood, brain, liver, kidney and bone. Ojeok-san proved to be safe, but more clinical studies regarding the safety are needed hereafter. 4. Papers related to analgesic, anti-pyretic, anti-phlogistic activities of Ojeok-san were in vivo studies, and other papers were about anti-hyperlipidemic activity, apoptosis inducing activity on uterine myeloma cell line and anti blood static activity on hydrocortisone acetate induced blood statis model. 5. Case reports were about anti-lipidemia, analgesic effect for mastalgia/back pain and anxiety disorder due to climacteric changes. Conclusion : Ojeok-san is being used in various ways with analgesic, anti-pyretic, anti-phlogistic, anti-hyperlipidemic, anti-tumor or anti-blood statis activity. However, mechanism study should be conducted at the molecular biology level and more clinical studies on the efficacy of Ojeok-san are needed.
Objective : Allergic Inflammation is related with secretion of Cytokine. This study was performed to examine the effects of Woobangja on anti-allergic inflammation. Method : While macrophage 264.7cells was chosen as a normal group a control group was classified into three groups. One was stimulated with LPS. and another was pretreated with Woobangja for 1 hour. The third was pretreated with gydrocortisone for 1 hour. After the pretreatment, macrophage were incubated with lipopolysaccharide(LPS) 100 ng/ml for 12h and media collected and $TNF-{\alpha}$, IL-6, $IL-1{\beta}$, IL-10 concentration in supernatants were measured each by Enzyme linked immuno-sorbent assay. Woobangja were used $50\;{\mu}g/ml$, $100\;{\mu}g/ml$, $250\;{\mu}g/ml$, $500\;{\mu}g/ml$, 1 mg/ml. Hydrocortisones were used respectively $10^{-8}\;M$,$10^{-7}\;M$,$10^{-6}\;M$,$10^{-5}\;M$,$10^{-4}\;M$. Results : Woobangja showed inhibitory effect on $TNF-{\alpha}$ by LPS-stimulated macrophage 264.7. The inhibitory effect was most significant in 1mg/ml(p<0.01), and has increased according to the number of doses. Woobangja also showed inhibitory effect on IL-10 by LPS-stimulated macrophasg 264.7. The inhibitory effect was most significant in $100\;{\mu}g/ml$, and was not in a dose-dependent manner as Hydrocortisone group. Woobangja and Hydrocortison showed contrary effect on $IL-1{\beta}$ in al five concentration(p<0.01), and at the lowest concentration ($50\;{\mu}g/ml$) the level of $IL-1{\beta}$ was the lowest. On the other hand hydrocortison was observed to have inhibitory effect on $IL-1{\beta}$ in all five concentration(p<0.01). IL-6 was inhibited by hydrocortison in a roughly dose-dependent manner, but was not inhibited by Woobangja. On the contrary Woobangja obviously increased the expression of $IL-1{\beta}$ in all five concentration(p<0.01), but it was not related with concentrations. Conclusion : 1. Woobangja does significantly inhibit the expression of $TNF-{\alpha}$ by LPS-stimulated macrophage 264.7. 2. Woobangja does significantly increse the expression of IL-6 by LPS-stimulated macrophage 264.7. 3. Woobangja does significantly increse the expression of $IL-1{\beta}$ by LPS-stimulated macrophage 264.7. 4. Woobangja does significantly inhibit the expression of IL-10 by LPS-stimulated macrophage 264.7. 5. Woobangja is observer to have anti-allergic inflammatory effect through inhibiting inflammatory cytokine.
This study investigated the properties of primary cultured proximal tubule cells in hormonally defined(insulin, transferrin, and hydrocortisone), serum-free medium or 10% serum-supplemented medium. The growth rate of the primary cultured proximal tubule cells was lower in the hormonally defined, serum-free medium than in the 10% serum- supplemented medium(p < 0.05), while the activities of brush border marker enzymes, alkaline phosphatase(AP), leucine aminopeptidase(LAP), and y-glutamyl transpeptidase(${\gamma}$-GTP) were increased(p < 0.05). The activities of these enzymes, however, decreased with the lapse of incubation time to 50-70% after 6 days culture compared to those of the freshly-prepared proximal tubules. The enzymatic activities of the primary cultured proximal tubul cells on 6, 9, 12, and 15 days of culture were significantly increased in the hormonally defined, serum-free medium compared to the 10% serum-supplemented medium(p < 0.05). The functional differentiation of the primary culture was examined by observing multicellular domes of the confluent monolayer, which is indicative of transepithelial solute transport. The dome formation by the proximal tubule cultures occurred at a higher frequency in the hormonally defined, serum-free medium than in the 10% serum-supplemented medium(p < 0.05). Upon electron microscopic examination, an increased density of the brush border was observed in the hormonally defined, serum-free medium compared to the cells grown in 10% serum-supplemented medium. The activities of $Na^+$glucose cotransporter($^{14}C$-a-MG uptake), $Na^+$phosphate cotransportere($^{32}P$ uptake) and $Na^+$ transporter($^{22}Na^+$ uptake) in the brush border membrane, and of $Na^+/K^+$-ATPase($^{86}Rb$ uptake) in the basolateral membrane were significantly stimulated in the hormonally defined, serum-free medium than in 10% serum-supplemented medium(p < 0.05). In conclusion, the primary cultured proximal tubule cells grown in the hormonally defined, serum-free medium demonstrated a slower growth rate, but the functions of cell were enhanced.

Surface epithelial cells isolated from hamster tracheas and grown on a thick collagen gel become a highly enriched population of mucus-secreting cells. Epithelial cells from tracheas of hamsters were collected using enzymatic procedures and cultured under various conditions. The medium used consisted of a 1:1 mixture of medium 199 and Dulbecco's modified Eagle's (DME) medium which was conditioned before use. Insulin, transferrin, hydrocortisone, epidermal growth factor, and extract from bovine hypothalamus were used as supplement. Due to relatively low basal rates of min secretion from in vitro cultures, cultures are generally radiolabeled using $^3$H-glucosamine as a metabolic precursor. The radiolabeled mucinsreleased are quantitated by precipitation with TCA/PTA. Using this cell culture system, we investigated mucin release of goblet cells by altering the media bathing the apical surface of hamster tracheal surface epithelial(HTSE) cells. Acidic media added sulfuric acid caused sigcificant increases in mucin relesse (155${\pm}$20% at pH 4 and 146${\pm}$16% at, pH 5). Ammonium hydroxide also increased mucin release at pH 9.0(156${\pm}$17%) and pH 10(295${\pm}$9%) respectively. This additional mucin release seems to be associated with cell membrane damage as indicated by release of cellular LDH. SP stimulates secretion of mucin in cultured HTSE cells(154${\pm}$16% at 1${\times}$10$\^$-6/M and 165${\pm}$25% at 1${\times}$10$\^$-5/M. PAF at 5${\times}$10$\^$-6/M and 5${\times}$10$\^$-5/M enhanced by HTSE cells in vitro 168${\pm}$34% and 259${\pm}$30% of mucin secretion, respectively. The increase in mucin release by PAF and SP was not secondary to cell damage or necrosis. SP and PAF may be in mediating mucous secretion induced by inflammation irritantion and infection.
Objective: This experimental study was performed to examine the in vitro and in viva anti-inflammatory and anti-allergic effects of Mori Cortex. Methods: Water extract of Mori Cortex was studied to its ability to stimulate or inhibit macrophage 264.7 cells to produce inflammatory and allergic mediators. Cytokines such as $IL-1{\beta}$, IL-6, IL-10 and $TNF-{\alpha}$ were measured by immunochemical assay. In vitro, the macrophages 264.7 were classified into four groups. One group was a normal group. The other group was a (-) control group stimulated with LPS. And the third group was a (+) control group pretreated for 1 hour with hydrocortisone. And the fourth group was a sample group pretreated for 1 hour with Mori Cortex. After pretreatment, macrophage were incubated with lipopolysaccharide(LPS) $100\;ng/m{\ell}$ for 12 hour and media collected and $IL-1{\beta}$, IL-6, IL-10 and $TNF-{\alpha}$ concentrations in supernatants were measured each by Enzyme linked immuno-soubent assay. Mori Cortex were used $50\;{\mu}g/m{\ell},\;100\;{\mu}g/m{\ell},\;250\;{\mu}g/m{\ell},\;500\;{\mu}g/m{\ell},\;and\;1,000\;{\mu}g/m{\ell}$. Hydrocortisones were used $10^{-8}M,\;10^{-7}M,\;10^{-6}M,\;10^{-5}M\;and\;10^{-4}M$. In vivo, the SD rats were classified into three groups. One group was a normal group injected with normal saline into the abdominal cavity. The other was a control group prescribed to compound 48/80 after normal saline injection. And the third was a sample group prescribed to compound 40/80 after Mori Cortex injection. Then, the release of histamine, IL-6 and $TNF-{\alpha}$ were measured. Results : In vitro, Man Cortex significantly increased the release of $IL-1{\beta}\;and\;TNF-{\alpha}$ by LPS-stimulated macrophage 264.7 cells. And it significantly decreased the release of IL-10. In IL-6, Mori Cortex of low concentration significantly decreased the release of IL-6, but that of high concentration acted in reverse. In vivo, Man Cortex didn't show significant inhibitory effects on the release of histamine and IL-6 in comparison with that of the control group. But it significantly increased the release of $TNF-{\alpha}$ in comparison with that of the control group.

Soybean polyunsaturated phosphatidylcholine (PC) is thought to exert anti-inflammatory activities and has potent effects in attenuating acute renal failure and liver dysfunction. The aim of this study was to investigate the effects of PC in protecting multiple organ injury (MOI) from lipopolysaccharide (LPS). Six groups of rats (N=8) were used in this study. Three groups acted as controls and received only saline, hydrocortisone (HC, 6 mg/kg, i.v.) or PC (600 mg/kg, i.p.) without LPS (15 mg/kg, i.p.) injections. Other 3 groups, as the test groups, were administered saline, HC or PC in the presence of LPS. Six hours after the LPS injection, blood and organs (lung, liver and kidney) were collected from each group to measure inflammatory cytokines and perform histopathology and myeloperoxidase (MPO) assessment. Serum cytokines (TNF-${\alpha}$, IL-6 and IL-10) and MPO activities were significantly increased, and significant histopathological changes in the organs were observed by LPS challenge. These findings were significantly attenuated by PC or HC. The treatment with PC or HC resulted in a significant attenuation on the increase in serum levels of TNF-${\alpha}$ and IL-6, pro-inflammatory cytokines, while neither PC nor HC significantly attenuated serum levels of IL-10, anti-inflammatory cytokine. In the organs, the enhanced infiltration of neutrophils and expression of ED2 positive macrophage were attenuated by PC or HC. Inductions of MPO activity were also significantly attenuated by PC or HC. From the findings, we suggest that PC may be a functional material for its use as an anti-inflammatory agent.

From the above findings, thd $So{\breve{u}}m$$Sipj{\breve{o}}ndaebot^{\prime}ang$ and the Gukbang $Sipj{\breve{o}}ndaebot^{\prime}ang$ groups also had an effect of Yang-insuffient syndrome, moreover, on Body thmperature, Body weight and Exercise time, both showed a singnificant effect.
Natural killer (NK) cells provide one of the initial barriers of cellular host defense against pathogens, in particular intracellular pathogens. Because bone marrow-derived hematopoietic stem cells (HSCs), lymphoid protenitors, can give rise to NK cells, NK ontogeny has been considered to be exclusively lymphoid. Here, we show that porcine c-$kit^+$ bone marrow cells (c-$kit^+$ BM cells) develop into NK cells in vitro in the presence of various cytokines [interleukin (IL)-2, IL-7, IL-15, IL-21, stem cell factor (SCF), and fms-like tyrosine kinase-3 ligand (FLT3L)]. Adding hydrocortisone (HDC) and stromal cells greatly increases the frequency of c-$kit^+$ BM cells that give rise to $CD2^+CD8^+$ NK cells. Also, intracellular levels of perforin, granzyme B, and NKG2D were determined by RT-PCR and western blotting analysis. It was found that of perforin, granzyme B, and NKG2D levels significantly were increased in cytokine-stimulated c-$kit^+$ BM cells than those of controls. And, we compared the ability of the cytotoxicity of $CD2^+CD8^+$ NK cells differentiated by cytokines from c-$kit^+$ BM cells against K562 target cells for 28 days. Cytokines-induced NK cells as effector cells were incubated with K562 cells as target in a ratio of 100 : 1 for 4 h once a week. In results, $CD2^+CD8^+$ NK cells induced by cytokines and stromal cells showed a significantly increased cytotoxicity 21 days later. Whereas, our results indicated that c-$kit^+$ BM cells not pretreated with cytokines have lower levels of cytotoxicity. Taken together, this study suggests that cytokines-induced NK cells from porcine c-$kit^+$ BM cells may be used as adoptive transfer therapy if the known obstacles to xenografting (e.g. immune and non-immune problems) were overcome in the future.
