Objective: This study was designed to assess antidepressant effects of Quibitang on an Animal Model of Depression induced by Chronic Mild Stress. Method: The consumption of 1% sucrose solution and active avoidance learning test were used to evaluate antidepressant effect of Quibitang. The consumption of 1% sucrose solution was measured every week for 8 weeks, and active avoidance learning test was executed after 4 weeks treatment of saline or Quibitang. Result: 1. The consumption of 1% sucrose solution was significantly reversed in test group (Quibitang-treated group) at 5th, 7th, 8th weeks, but there was no significant change in control group. 2. Chronic Mild Stress was found to suppress the increase of body weight at 5th, 6th, 7th, 8th weeks. Treatment of Quibitang did not enhanced the body weigt, but it enhanced the consumption of sucrose solution. 3. In order to measure the learning ability of rat which drived to be depressed, we executed active avoidance test. The result revealed that depressed rat showed impaired acquisition than control group, and the treatment of Quibitang restored the learning activity. Conclusion: These results suggest that Quibitang may have antidepressant effects on depression induced by chronic mild stress.

BACKGROUND/OBJECTIVES: The exposure to sucrose in rats has mimic abnormalities attributed to metabolic syndrome (MetS). The effects of honey bee and "free" glucose and fructose, have not been explored in this context. The aim was to expose Wistar rodents to sucrose solution (SS), honey solution (HS) and fructose/glucose solution (GFS) at 30% to assess their effects. SUBJECTS/METHODS: HS (n = 10), SS (n = 10) and GFS (n = 10) groups were formed. Solutions were ad libitum along 14-weeks. RESULTS: Between solutions consumptions, honey was significantly 42% higher (P = 0.000), while similar consumption was observed among GFS and SS. The feeding pattern of HS consumption was irregular along experiment; while the food intake pattern showed the similar trend among groups along time. Non statistical differences were obtained in any biochemical and anthropometric measure, however, a higher concentration of leptin (721 ± 507 pg/mL), lower concentration of total cholesterol (TC; 48.87 ± 2.41 mg/100 mL), very low density lipoprotein (VLDL; 16.47 ± 6.55 mg/100 mL) and triglycerides (82.37 ± 32.77 mg/100 mL) was obtained in SS group. For anthropometric values, HS showed less total adipose tissue (AT; average 26 vs. 31-33 g) and adiposity index (average 6.11 vs. 7.6). Due to sugar-sweetened beverages consumption increases the risk for the development of chronic diseases; correlations between fluid intake and anthropometric and biochemical parameters were assessed. A moderate correlation was obtained in groups with the weight of total AT and solution intake; for the weight gain in GFS group and for triglycerides in HS and GFS. The highest hepatic tissue damage was observed in SS group with multiple intracytoplasmic vacuoles, atypia changes, moderate pleomorphism and hepatocellular necrosis. CONCLUSIONS: In spite of the significantly higher consumption of HS, biochemical, anthropometrical and histological effects were not remarkably different in comparision to other sweeteners.

This study was performed to investigate the anti-depression effect of Guibiondamtang in rat model of depression. The rats in the experiment were stratified into 3 groups, ie, Guibiondamtang, saline, normal (non-stressed) groups. Chronic exposure to mild unpredictable stress such as white noise, flashing lights and restriction of food and water, causes the behavioral symptoms correspondent to depression. Consumption of 1% sucrose solution fell in rats exposed to CMS for 4 weeks. In the open field test , the exploratory activity ie. locomotion and centering decreased after CMS. We then evaluated the sucrose consumption and activity during 4 weeks of treatment with experimental drugs. The results were as follows: 1) There was no relation between sucrose intake and weight. 2) The Guibiondamtang(歸脾溫膽湯) group reinstated sucrose consumption within 5-6 weeks while having no influence on sucrose intake in normal group. 3) The Guibiondamtang(歸脾溫膽湯) group restored some exploratory activity in the open field test. 4) The Guibiondamtang-group had a-reduced potentiated startle response.

Purpose: Some of the adolescent drinks more sugar-sweetened beverages. However, there is little evidence on the effect of eating behavior on emotional state and neurochemical changes under stress, especially on the levels of typical inhibitory neurotransmitters and gamma-aminobutyric acid. This article demonstrates that sucrose or saccharin drink reduces stress-related behavior responses and GABAergic deficits in adolescent rats. Methods: We randomly assigned 7-weeks-old Sprague-Dawley male rats to three groups: control group (Control), restraint stress only group (Stress), and restraint stress with unrestricted access to saccharin solution (Saccharin) and sucrose solution (Sucrose) as a positive control. We evaluated both anxious and depressive moods using an open field test and forced swim test, respectively. Using western blot analyses, the expression of a GABA-synthesizing enzyme, glutamate decarboxylase-67 (GAD67) and GABAergic markers, including calbindin and parvalbumin was assessed in the prefrontal cortex and the amygdala. Results: We found that both the drinks alleviated anxiety and depressive moods, induced significant attenuation in GAD67 level, and reduced calbindin level under stress in the prefrontal cortex and the amygdala. Conclusion: The results provide an understanding of the effect of sucrose or saccharin drink on stress-related responses. We propose the consumption of sweet drinks as a plausible strategy to alleviate stress-related alterations in adolescents.

Sensory factors are important determinants of appetite and food choices but little is known about factors affecting taste acuity and preference of Koreans. Any factors causing deficits in sweet taste perception may lead to over consumption of simple sugar, which is related to several chronic diseases. This study was conducted to determine factors affecting sweet taste sensitivity and preference. Subjects were 30 government employees who were serving as school dietitians or in the area of public health while they were studying in the program for the qualification to become nutrition teachers. Sweet taste threshold and the optimally-preferred sweetness of omija jelly were determined by a sensory evaluation and general characteristics, health-related lifestyles, dietary habits and food preferences were determined using a self-administered questionnaire. For the subjects of this study, detection threshold concentration of sucrose solution was $0.184{\pm}0.06%$ and optimally-preferred sucrose concentration of omija jelly was $13.88{\pm}2.28%$ and there was no significant correlation between the sweet taste sensitivity and preference. Subjects who had higher(${\ge}4$ out of 10) physical or psychological stress and who had late getting-up time (after 7am) tended to have lower sweet taste threshold (higher sensitivity) than their counterpart. The sweet taste preference determined by optimally-preferred sucrose concentration of omija jelly tended to be lower in the subjects who eat slowly. Those who answered in the questionnaire to prefer sweet foods did have significantly higher optimally-preferred sucrose concentration of omija jelly. Further research is required to determine whether decreased sensitivity and increased preference for sweetness can increase the actual intake of simple sugar.

This study was performed to investigate the change in taste perception during aging and its effects on dietary intake in Korean elderly. The subjects were female aged 65 through 90 in the Anyang area, and college women were included as a comparison group . Dietary intake of the elderly(n=155) and young subjects (n=38) was measured by a 3 day diet record. The taste threshold and 'just right' concentrations(JRC) for sweet and salty tastes were assessed by sensory evaluation . Sucrose solution (0.0.,0.4,0.6,0.8,1.0, 1.2%) and salt solution(0, 0.02, 0.03,0.06,0.09,0.12,0.15%) were used to establish thresholds. for JRC assessment, four suprathreshold sucrose concentrations of 5, 8, 11 and 14% in orange-pineapple flavored juice and salt concentrations of 0.20, 0.34, 0.50and 0.75% in beef stock were prepared. Mean intakes of energy, protein , vitamin A, thiamin , riboflavin, niacin ,calcium and iron of the elderly were below the Korean Recommended Dietary allowances. The elderly showed higher taste thresholds than young subjects of both sweet and salty tastes consumed less calories. Needs to bespecified. The older subjects having high threshold or JRCs for sweet and salty tastes consumed fewer calories from protein and fat. Pearson correlation coefficients was between JRC for sweet and salty tastes 0.54(p<0.01). The correlation coefficients between tastes threshold and nutrient intakes were very low for both age groups. Unlike the college women, in the elderly the JRC of sweet taste of the orange-pineapple juice were negatively correlated with intakes of energy, protein, fats, thiamin , riboflavin , niacin ,vitamin C , iron and consumption of meat and egg food groups (p<0.01). In summation age-related alterations in sweet and salty taste perception were observed in the elderly and dietary intakes of the elderly see to be influenced by these taste perception changes.

BACKGROUND/OBJECTIVES: The primary objective of the treatment of diabetes mellitus is the attainment of glycemic control. Hyperglycemia increases oxidative stress which contributes to the progression of diabetic complications. Thus, the purpose of this study was to investigate the hypoglycemic and antioxidant effects of Daraesoon (Actinidia arguta shoot) in animal models of diabetes mellitus. MATERIALS/METHODS: Rats with streptozotocin-induced diabetes received an oral administration of a starch solution (1 g/kg) either with or without a 70% ethanol extract of Daraesoon (400 mg/kg) or acarbose (40 mg/kg) after an overnight fast and their postprandial blood glucose levels were measured. Five-week-old C57BL/6J mice were fed either a basal or high-fat/high-sucrose (HFHS) diet with or without Daraesoon extract (0.4%) or acarbose (0.04%) for 12 weeks after 1 week of adaptation to determine the effects of the chronic consumption of Daraesoon on fasting hyperglycemia and antioxidant status. RESULTS: Compared to the control group, rats that received Daraesoon extract (400 mg/kg) or acarbose (40 mg/kg) exhibited a significant reduction in the area under the postprandial glucose response curve after the oral ingestion of starch. Additionally, the long-term consumption of Daraesoon extract or acarbose significantly decreased serum glucose and insulin levels as well as small intestinal maltase activity in HFHS-fed mice. Furthermore, the consumption of Daraesoon extract significantly reduced thiobarbituric acid reactive substances and increased glutathione levels in the livers of HFHS-fed mice compared to HFHS-fed mice that did not ingest Daraesoon. CONCLUSIONS: Daraesoon effectively suppressed postprandial hyperglycemia via the inhibition of ${\alpha}$-glucosidase in STZ-induced diabetic rats. Chronic consumption of Daraesoon alleviated fasting hyperglycemia and oxidative stress in mice fed a HFHS diet.
