  • This study was conducted to investigate the effect of total neutral detergent fiber (NDF) and forage-derived NDF (fNDF) on nutrient intake and milk production in Holstein dairy cows. Thirty-six Holstein dairy cows at weeks 4 to 20 of lactation were included in this study. The cows were arranged in a randomized complete block design and assigned to one of six diets: 1) 38% NDF with 18% fNDF (HN-HF); 2) 38% NDF with 15% fNDF (HN-MF); 3) 38% with 12% fNDF (HN-LF); 4) 34% NDF with 18% fNDF (LN-HF); 5) 34% NDF with 15% fNDF (LN-MF); and 6) 34% with 12% fNDF (LN-LF). The cows were fed a total mixed ration twice daily (07:00 and 18:00 h) and given ad libitum access to feed and water throughout the experiment. Data on the intake of nutrients (DM, NEl, CP, NDF, fNDF, NFC), milk yield, composition, fat-corrected milk (FCM), fat and protein corrected milk (FPCM), and energy corrected milk (ECM) were analyzed. Lower dietary concentrations of total NDF or fNDF resulted in an increase in DM, NEl, and NFC intake (p<0.01), milk yield (p<0.05) and a lower milk fat concentration (p<0.01). The LN treatment showed no significant differences in milk fat concentration compared to the HN however, further reduction in fNDF decreased milk fat content (p<0.01). The lowest level of milk fat was observed in the LN-LF diet group. Changes in the dietary concentrations of NDF or fNDF did not affect the concentrations of milk protein or SNF (solid not fat), although the yield of milk protein and SNF increased with higher milk yield (p<0.01). The level of fNDF influenced the level of FCM (p=0.07), as well as FPCM and ECM yield (p<0.05). A highly positive correlation between fNDF intake and milk fat concentration was observed in animals with low NDF compared to those offered high NDF. A strong correlation was also observed between milk yield and low NDF intake compared to high NDF intake.

  • Oral cancer take up 2-6% of all carcinomas and squamous cell carcinoma, which is the most common type in oral cancer, has a poor prognosis due to its high metastasis and recurrence rates. In treating oral cancer, chemotherapy to the primary, metastasized and recurrent lesion is a very important and useful treatment, even though its widespread usage is limited due to high general toxicity and local toxicity to other organs. Taxol, a microtubule stabilizing agent, is an anticancer drug that induces cell apoptosis by inhibiting depolymerization of microtubules in between the metaphase and anaphase of the cell mitosis. Recently, its effectiveness and mechanism on various tumor has been reported. However, not much research has been done on the application of Taxol to oral squamous cell carcinoma. Cyclosporin A, which is an immunosuppressant, is being used on cancers and when co-administered with Taxol, effectiveness of Taxol is enhanced by inhibition of Taxol induced multidrug resistance. In this study, Cyclosporin A with different concentration of Taxol was co-administered to HN22, the oral squamous cell carcinomacell line. To observe the cell apoptosis and the mechanisms that take part in this process, mortality evaluation of tumor cell using wortmannin, c-DNA microarray, RT-PCR analysis, cytometry analysis and western blotting were used, and based upon the observation on the effect and mechanism of the agent, the following results were obtained: 1. The HN22 cell line viability was lowest when $100{\mu}M$ of Wortmannin and $5{\mu}g/ml$ of Taxol were co-administered, showing that Taxol participates in P13K-AKT1 pathway. 2. In c-DNA microarray, where $1{\mu}g/ml$ of cyclosporine A and 3mg/ml of Taxol were co-administered, no up regulation of AKT1, PTEN and BAD c-DNA that participate in cell apoptosis was observed. 3. When $1{\mu}g/ml$ of Cyclosporin A was applied alone to HN22 cell line, no difference was found in AKT1, PTEN and BAD mRNA expression. 4. Increased AKT1, mRNA expression was observed when $3{\mu}g/ml$ of Taxol was applied alone to HN22 cell line. 5. When $1{\mu}g/ml$ of Cyclosporin A and Taxol($3{\mu}g/ml\;and\;5{\mu}g/ml$) were co-administered to HN22 cell line, PTEN mRNA expression increased, whereas AKT1 and BAD mRNA decreased. 6. As a result of cytometry analysis, in the group of Cyclosporin A($1{\mu}g/ml$) and Taxol($3{\mu}g/ml$) co-administration, increased Annxin V was observed, which shows that apoptosis occurred by deformation of plasma membrane. However, no significant difference was observed with vary ing concentration. 7. In western blot analysis, no caspase 3 was observed in the group of Cyclosporin A($1{\mu}g/ml$) and Taxol($3{\mu}g/ml$) co-administration. From the results of this study, it can be concluded that synergistic effect can be observed in combination therapy of Taxol and Cyclosporin A on oral squamous cell carcinoma cell line, where decreased activity of the cell line was observed. This resulted in decreased AKT1 and BAD mRNA and increased PTEN mRNA expression and when wortmannin and Taxol were co-administered, the viability decreased which confirms that Taxol decreases the viability of tumor cell line. Hence, when Taxol and cyclosporine A are co-administered, it can be assumed that cell apoptosis occurs through AKt1 pathway.

  • This study was conducted to compare the physicochemical properties of powdered green teas produced in Korea and Japan including particle size, color, chlorophyll, caffeine and theanine. The average particle size of Korean powered green tea ($14.63-25.39\;{\mu}m$) was similar to that of Japanese powdered green tea ($15.46-21.02\;{\mu}m$). The surface color of shade-cultivated Haenam Green Tea (HN-1) had the highest negative 'a' value, which represents 'green' color. When the TCD (total color difference value) was measured in the samples, HN-1 was most similar to the premium powdered green tea of Japan (JA-1). Domestic shade-cultivated powdered green teas had 1.5-2 times greater chlorophyll content than powdered green teas produced from plants that were not cultivated in the shade. The presence of chlorophyll a resulted in a higher intensity of green color than the presence of chlorophyll b. A significant negative correlation was also observed between the color and the chlorophyll a, chlorophyll b and total chlorophyll contents. Specifically, chlorophyll a had the greatest impact on the green color of powdered green tea. The content of catechins, caffeine and theanine in Korean powdered green teas ranged from 14.679-20.128, 1.496-3.237 and 0.926-1.977 g/100 g, respectively. The caffeine and theanine contents were high in shade-cultivated powdered green teas. Based on the above results, domestic powdered green teas cultivated under shaded conditions had a quality similar to that of medium-quality green teas produced in Japan, and the overall quality of Korean powdered green tea was poorer than that of Japanese powdered green tea.

  • Purpose: The purpose of this study was to compare symptom severity and the impact of presence of depressive and/or anxiety symptoms among patients with head and neck cancer (HNC). Methods: One hundred and fifteen patients diagnosed with HNC completed two questionnaires: Hospital Anxiety and Depression Scale (HADS) and the M. D. Anderson Symptom Inventory-Head and Neck Cancer (MDASI-HN). Results: Of the total sample, 55.6% reported depressive symptoms and 33% reported anxiety symptoms. Patients who reported either depressive or anxiety symptoms also had significantly more severe symptoms. The most severe symptom was dry mouth. Participants who were depressed reported that interference in the enjoyment of life due to symptoms was the most distressing whereas participants with anxiety reported symptom interference in work was of most concern. Of patients reporting moderate to severe symptoms, more than 60% reported depressive symptoms. Of patients reporting moderate to severe feelings of being distress and feeling sad, more than 70% reported anxiety symptoms. Conclusion: Patients with HNC reporting moderate to severe symptoms also report depressive and/or anxiety symptoms. The results suggest the need to develop an integrated nursing intervention of both physical and emotional symptoms for patients with HNC.

  • Objectives: To perform a systematic review of placenta pharmacopuncture for treating neuropsychiatric diseases, focusing on its efficacy and the safety so that evidence on its clinical use could be obtained, thus contributing to further studies. Methods: Through Korean, English, and Chinese databases (OASIS, Korean TK, KISS, RISS, ScienceON, Pubmed, Cochrane, EMBASE, CINAHL, AMED, CNKI, and Wanfang), combinations of keywords (placenta, pharmacopuncture, etc.) were used to select clinical studies published until January 2021 about placenta pharmacopuncture for neuropsychiatric diseases. Interventions included combined treatments. Study design included cases studies, series, and clinical trials. Cohort studies, literature reviews, in vitro and animal experiments were excluded. The primary outcomes involved measurements of symptoms, Visual Analogue Scale, or questionnaires. Data extracted from databases were imported to Endnote X7 to remove duplicates. The quality of the literature was assessed based on CAse REports Guidelines and Cochrane's Risk of Bias (ROB). Results: Twenty-one studies were selected, including ten case reports, three case series, two one-armed clinical trials, one non-randomized clinical trial, and five randomized clinical trials. There were six studies on sleep disorders, five studies on stroke sequela, two on mood disorders, two on enuresis, two on Guillain-Barré syndrome, two on multiple sclerosis, one on neurocognitive disorder, and one on vertigo. The most frequent combined treatment was acupuncture in both the experimental group (n=10) and the control group (n=3). Acupoints were ST36, SP6, BL23, CV4, GB20, GV20, N-HN54, and so on. All studies reported improvement of symptoms. The quality of case studies was relatively high. Assessment of ROBs resulted in low risks. Conclusions: Placenta pharmacopuncture is effective for neuropsychiatric diseases such as sleep disorders, mood disorders, enuresis, and neurocognitive disorders. Regarding insomnia, several studies have reported significant improvements with placenta pharmacopuncture. There was no adverse event associated with placenta pharmacopuncture.
