Response of two ploidy levels to cool temperature and short day treatment were investigated under controlled conditione of Phytotron. The haploid and diploid of seven genotypes were started and grown to the 8- leaf stage in the greenhouse. They were treated during 15 and 20 days to 8- hour photoperiods at 18$^{\circ}C$ in controlled - environmental room to induce premature flowering, respectively. Diploid plants of seven genotypes flower later than their haploid plants at 20 days treatment. But under 15 days treatment, diploid plants of NC82, Hicks, BY4, NC2326 and Coker86 were not different from their haploid plants for days to flower. Diploid plants of seven genotypes developed the same number of leaves as their haploid plants at 20 days treatment. Under 15 days treatment, diploid plants of Coker347 and NC95 developed more leaves per plant than their haploid plants. Correlation coefficient between the ranks of leaves per plant of seven genotypes at two ploidy levels was 0.964 and 0.929 at 15 and 20 days treatment, respectively.
In traditional costume, colors have been used to express the religion, society, culture, custom, and other aspects of a country. This is mainly due to color being the most conspicuous visual factor of a costume. In Thailand, there is a symbolic color for each day of the week, and the purpose of this study is to contribute to deeper understanding of the Thailand culture in regards to color and its costumes. The study method is as follows: literatures and photos were researched for social and religious background of the seven days Buddha history, which was the source of the color a day culture, symbols and significance of each Buddha were studied and precedent studies were reviewed. The study attempted to investigate the effect of the symbolic color on costumes as it passed down from generations. Originally, the symbolic colors of seven days Buddha in Thailand was a religious component that was exclusive to the upper class. However, it has expanded to the lower classes today. Currently, it obtains an aspect of health and wealth gospel for oneself or others as well as being used to express individual personality because people regard certain color as their symbolic color.
BACKGROUND/OBJECTIVES: Propolis has a rich source of bioactive compounds and has renal and hepatic protective properties. The purpose of this study was to investigate the beneficial effect of hydro-ethanolic extract of propolis against paracetamol-induced liver damage and impairment of kidney function, as well as hematological changes in rats. MATERIALS/METHODS: Six groups of rats were used; the first group was served as a control; the second and third groups were treated by propolis extract at a dose of 50 and 100 mg/kg.B.WT. respectively; the fourth group was treated by paracetamol (200 mg/kg.B.WT.); the fifth group was treated by propolis (50 mg/kg.B.WT.) for eight days and then received similar dose of propolis for following seven days with paracetamol at a dose of 200 mg/kg.B.WT. daily for the seven days; and the sixth group was treated with propolis (100 mg/kg.B.WT.) for eight days and then received similar dose of propolis for following seven days with paracetamol at a dose of 200 mg/kg.B.WT. daily for the seven days. All the animals were treated for a period of 15 days. At the end of the experimental period, blood samples were collected for measurement of the liver enzymes, serum albumin, protein and creatinine, blood urea nitrogen, hematological parameters, and urine volume, protein and albumin. RESULTS: Paracetamol over dose significantly lowered hemoglobin, serum total protein, albumin, and uric acid, while it significantly increased blood creatinine, blood urea nitrogen, alanine aminotransferase, aspartate aminotransferase and lactate dehydrogenase activities, white blood cells, and platelet count as compared to the control. However, these alterations were significantly attenuated by the use of propolis extract and the effect was dose dependent. Interestingly, propolis prevented paracetamol induced proteinuria, low hemoglobin and body weight loss. CONCLUSIONS: Propolis significantly prevented paracetamol induced renal, hepatic and hematological toxicity and might be useful in the management of liver and renal diseases particularly proteinuria.

Backgrounds/Aims: Early recovery after surgery has become a popular trend. The aim of this study was to evaluate effect of nutritional intervention using Encover, an oral nutritional supplement, in patients undergoing hepato-biliary-pancreatic surgery. Methods: This single center, prospective case-control study was conducted in Gangnam Severance Hospital from September 2018 to April 2019. Through randomization, patients were divided into an experimental group (30 patients) and a control group (30 patients). At postoperative seven days, the experimental group was instructed to take two packs of Encover (JW Pharmaceutical, Seoul, Korea) daily for seven days. Body cell mass index was measured at seven days after surgery and 14 days after discharge and Patient-Generated Subjective Global Assessment (PG-SGA) was performed at 14 days after discharge. Results: Body cell mass index during outpatient follow-up was significantly decreased compared to that at discharge in both groups. However, the amount of body cell mass index showed no significant difference between postoperative seven days and outpatient follow-up in either group. During outpatient follow-up, the experimental group had a higher mean value of PG-SGA score than the control group (11.32 ± 3.46 vs. 9.48 ± 3.97; p = 0.037). Conclusions: Short-term Encover doses after surgery may not produce significant results in weight gain or other body cell mass index. Encover did not significantly affect other dietary conditions based on PG-SGA.
Even though gratitude is considered as an important virtue to possess for successful adulthood, little is known about what cultivates gratitude and its benefits associated with psychological well-being among adolescents. By examining gratitude as a daily mood, this study asked (1) whether adolescents' daily grateful mood varied as a function of daily parental emotional support and (2) whether adolescents' psychological well-being varied as a function of daily grateful mood within person across seven days. The sample consisted of 70 adolescents in 8th grade recruited from a public middle school. Participants completed daily diary checklists online each evening for seven days. On days when adolescents perceived greater parental emotional support from mother or father than they typically did during the week, they rated their grateful mood to be higher than other days. With more emotional support from father, adolescents reported more grateful mood not only on that day, but also the following day. While this result highlights the important role that parents play in adolescents' experience of grateful mood, emotionally supportive behaviors of fathers appear particularly promising for cultivating gratitude. Further, daily grateful mood on a given day accounted for the significant variance in adolescents' psychological well-being not only on the same day, but also the following day. Research and practical implications of the results are discussed.
Recurrent aphthous stomatitis is one of the most common diseases of ulcerative oral mucosal lesions and its cause remains elusive. The purpose of this study is to evaluate the therapeutic effect of topical steroids for the treatment of recurrent aphthous stomatitis. We performed the study with 50 cases who had visited to our office for the treatment of recurrent aphthous stomatitis during the recent five years. We devided 50 cases into five groups. Group 1 is that triamcinolone of 0.1-0.2mg was injected into the submucosal lesions of ulcerations. Group 2 is that the gargling of 5ml with triamcinolone tablet of 2mg was used three times per day for seven days. Group 3 is that the gargling of 5ml with betamethasone tablet 0.5mg was used three times per day for seven days. Group 4 is that tetracycline gargling was used six times per day for seven days. Group 5 is that normal saline gargling was used six times per day for seven days. The retrospective analysis of results were as follows : Betamethasone gargling was effective in the treatment of minor aphthous stomatitis and the submucosal injection of triamcinolone was effective in the treatment of major aphthous stomatitis, but none of the different therapeutic methods was effective for herpetiform stomatitis. In the evaluation of mean recurrence periods, the triamcinolone gargling and betamethasone gargling showed longer asymptomatic periods than other methods. We concluded that some kinds of topical steroids can be used for the treatment of recurrent aphthous stomatitis but the proper selection of agents according to the type of the disease is important for the treatment.
It was previously reported that cytochrome P$_{450}$ content in liver was increased when Capsicum acetone extract was given chronically to rats. The present study is aimed to investigate the effect of capsaicin, a principal component of red pepper, on the drug metabolizing enzymes in rat liver. Capsaicin (5mg/kg) was given intraperitoneally once a day for seven days and zoxazolamine paralysis time and hexobarbital sleeping time were determined 24 hrs after the last dose of capsaicin. Plasma hexobarbital concentration was also determined five and 15 min after hexobarbital administration to rats. Zoxazolamine paralysis time and hexobarbital sleeping time were shortened by 31.6% and 37.1%, respectively, compared with control group. Plasma hexobarbital concentration was lowered by 26.2% after five min and by 35.2% after 15 min, respectively, compared with control group. However, administration of single dose of capsaicin did not affect the zoxazolamine paralysis time and hexobarbital sleeping time. Microsomal cytochrome P$_{450}$ content and NADPH-cytochrome C reductase activity were increased by 14.6% and 11.6%, respectively in the rats pretreated with capsaicin for seven days, while cytochrome b$_{5}$ content was not changed. These results suggest that treatment with capsaicin for seven days may induce the drug metabolizing enzyme in rat liver.
Purpose : The purpose of this study is to identify the clinical effects of acupuncture and herbal medication in the treatment of primary dysmenorrhea during five or seven days before menstruation. Methods : This study was carried out to the 17 female students in kyungwon university without pelvic or other systemic disease and its history. We investigated general and menstrual characteristics through questionnaires and treated sample patients with crossover acupuncture treatment(Sojangjeonggyeok & $SP_6$) and herbal medication(Hyunburikyungtang-gagam) during five or seven days before menstruation two times. And the change of pain was measured by the method of VAS after menstration monthly two times. Results : The improvement frequency of pain after treatment according to VAS all got better after one, two months of treatment. Especially, the mean${\pm}$S.E. of VAS score after 2nd month treatment was decreased significantly compared with that of 1st month treatment(p<0.05). And Between acupuncture treatment and herbal medication groups had no significant differences on the efficacy of treatment. Conclusion : The acupuncture treatment or herbal medication during five or seven days before menstruation will be efficacious against primary dysmenorrhea.
Background: Temporary crown resins are used prior to prosthesis placement, indicating the importance of aesthetics. The aim of this study was evaluate the color stability of various staining solutions according to the color of temporary crown resins using VITA EasyshadeⓇ V. Methods: The temporary crowns used were the powder-liquid type and included four shades. A total of 36 specimens were fabricated in the form of disks with a diameter of 1.8 mm and a depth of 2 mm. They were divided into four groups of nine each, and staining was performed for seven days by precipitation in 3 mL of three staining solutions composed of distilled water, black coffee, and red wine. Color and color stability evaluations were performed by a trained examiner using a digital spectrophotometer (VITA EasyshadeⓇ V). Color stability was analyzed using the ΔE value. Results: Because of the color stability evaluation using the ΔE value, the difference between three and seven days was significant in the specimen I and III groups (p<0.05). Further, post hoc analysis showed that the ΔE value of red wine was significant, indicating that the color stability in red wine was low. The ΔE values in group II between days three and seven were statistically significant (p<0.05). Post hoc analysis showed that distilled water, coffee, and wine had the highest ΔE values on day three. On day seven, the ΔE value for wine was significant, and the color stability was low. There was no significant difference in group IV according to the staining period and staining solution; therefore, color stability was high (p>0.05). Conclusion: This study showed that most temporary resin restorations exhibited color stability in the staining solution. The darker the color of the temporary resin restoration, the higher the color stability against extrinsic staining.
In this study, we investigated changes in some physico-chemical and biochemical properties of Kimchi during fermentation and storage. After fermenting Kimchi at $15^{\circ}C$ for 23, 36, 40, 44, and 60 hrs during the first week, we stored it at $-1^{\circ}C$ in a Kimchi refrigerator until the end of 8th week. The pH of samples fermented for 36 hr, 40 hr, 44 hr and 60 hr sharply decreased during the first seven days and then slowly decreased. Acidities of samples fermented for 36 hr, 40 hr and 44 hr sharply increased for the first seven days. According to measured changes of lactic acid bacteria number, samples fermented for 60 hr revealed the largest augmentation in the number of lactobacilli for the first seven days. The $\gamma$-aminobutyric acid (GABA) content of the sample fermented for 40 hr was the most superior, with an early increase and maintenance of GABA content, which maintained a maximum 20 mg per 100 g of Kimchi sample on the seventh, fourteenth, and twenty eighth days. These results suggest that relatively enhanced levels of GABA in Kimchi samples can be produced and maintained by controlling the fermentation and storage processes, as with the 40 hr fermented sample conditions.
