This study was conducted to examine the possibility of Salicornia herbacea L. powder as a functional food beneficially affecting carbohydrate metabolism and antioxidant capacity. Twenty-four, 6-week old, maleSprague-Dawleyrats were classified into three groups: normal diet control (CON), high-fat diet control (HFC) and high fat diet + Salicornia herbacea L. (SHF). Related feed was provided to each group for 4 weeks. Weight gain rate increased most in the HFC rats, and the concentration of glucose was significantly high in both the HFC and SHF groups, compared to the CON group. The SHF group showed a significantly high expression rate of Glut 4 (21.36%), compared to the CON and HFC groups. The glycogen content in muscle was significantly high in both the HFC and SHF groups, compared to the CON group. There were significant differences in the malondialdehydecontent in muscles between the groups, with the content in the CON and HFC groups being significantly higher than the SHF group. All the groups showed a similar tendency to each other in the liver tissue as well. Concerning the expression of Cu,Zn-super oxide dismutase andglutathione peroxidaseproteins, the SHF group was significantly higher than the CON and HFC groups. Overall, the experiment result above implies a possibility that an intake of Salicornia herbacea L. powder can regulate weight by decreasing the weight gain rate, further suggesting its effectiveness as a functional food before exercise by increasing the energy storage capacity and antioxidant capacity.

This study was carried out to investigate the effect of Salicornia herbacea L. (SHL) intake and acute exercise on lipids metabolism in streptozotocin (STZ)-induced diabetic rats. Four different groups of 40 STZ-induced diabetic Sprague-Dawley male rats were given a diet of feed mixed with SHL powder for 6 weeks. To adapt to the acute swimming exercise, the exercise group went through a period of swimming induction over one week. Then, they performed the acute swimming exercise the next day. 24 hours after the acute swimming exercise, the rats were sacrificed and samples were collected and analyzed. There was no significant change in body weight as compared to the control group. Stored fat was found to have decreased in the group which was fed a diet supplemented with SHL powder. There was a significant reduction in blood glucose, triglyceride and total-cholesterol in the SHL intake group only. There was no change in L-FABP and CPT-1 protein expression determined to have occurred due to acute exercise, but there was a statistically significant increase in the expression of both proteins determined for the SHL grouip. Moreover, the SHL group with acute exercise exhibited an increase in cytochrome C oxidase. Based on the results above, it seems that SHL powder could help to prevent various diabetic complications. In addition, it seems necessary to prove the effectiveness of SHL as a healthy functional food by carrying out further research on its intake in relation to metabolic syndromes and exercise capabilities.

본 연구에서는 함초분 섭취가 지질대사에 미치는 영향을 알아보고자 하였다. 흰쥐를 일반식이 대조군(CON), 고지방식이 대조군(HFC), 고지방식이에 함초분 첨가군(HFG)로 각각 구분하여 4주간 섭취시켰다. 체중은 HFG가 HFC에 비하여 9% 정도 낮았다. 분변칼로리 분석을 한 결과, HFG의 지방량(CON에 비하여 120%, HFC에 비하여 138)과 분변 칼로리(약 110%)가 높은 것으로 나타났다. 혈중 중성지방과 LDL-C는 HFG가 HFC에 비하여 낮았으며(각각 71.8% 및 58%), HDL-C는 HFG가 HFC에 비하여 152% 높았다. 간의 FABP 발현은 HFG가 HFC보다 197% 높았으며, CPT-1 역시 동일한 경향을 보였다. 이러한 결과는 함초분 섭취가 체중의 증가를 억제하였고, 간세포 수준에서의 지방대사를 개선하였다는 점을 시사한다. 이러한 결과를 함초분이 소화관에서의 지방흡수를 억제함으로써 항비만 효과를 가지는 것으로 제안하고자 한다. The purpose of this study was to investigate the effects of glasswort powder intake on lipid metabolism. Rats were divided into three groups: a group fed a normal diet (CON), one fed a high fat diet (HFC), and one fed a high fat diet with glasswort powder (HFG). They were fed their respective diet for four weeks. Body weight was significantly lower (9%) in the HFG group than in the HFC group at the fourth week. According to the feces analysis, the HFG group showed the highest fat level (120% vs. CON; 138% vs. HFC) and fecal calories (110%). The concentration level of TG and LDL-C was 71.8% lower in the HFG group compared to the HFC group, while the concentration level of HDL-C was 152% higher in the HFG group. Expression of FABP in the liver was 197% greater in the HFG compared to the HFC group, with the expression of CPT-1 showing a similar tendency. These results suggest that glasswort powder intake suppresses weight gain and improves fat metabolism at the level of liver cells. From these results, we suggest that glasswort powder is effective against obesity by inhibiting the absorption of fat in the digestive tract.

[Purpose]This studyinvestigated the effect of the vinegar, which is made of 4-year-old mountain-cultivated ginseng ripened into 4-year-matured persimmonvinegar, on the blood lipids level and inflammatory cytokines concentration in obese female adolescents. [Methods]Subjects ingestedthe vinegar, so-called ``mountain-cultivated ginseng persimmon vinegar (MPV)``, without meals every day for 6 weeks with activitiescontrol. Subjects were grouped into control (CON), persimmon vinegar (PV), and MPV with 10 people in each group. Bloodlipids, triglyceride (TG), total-cholesterol (TC), and high density lipoprotein-cholesterol (HDL-C) were analyzed. Also, glutamicoxaloacetic transaminase (GOT) and glutamate pyruvate transaminase (GPT) were analyzed for the hepatotoxicity. Blood cytokines,interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and nuclear factor kappa-light-chain-enhancer of activated B cells (NFκB)were analyzed. [Results]Subjects showed a high reduction in body weight and body fat. Their blood lipid level was effectivelyimproved, and the secretion of inflammatory cytokine was suppressed as well, except for TNF-α. However, the change ratio ofthe cytokines was high in PV and MPV. Such results were similar to those from research subjects who took persimmon vinegaronly (PV), but the effect of the vinegar (MPV) was more remarkable. Besides, this mixture was found to have no effect onthe hepatotoxicity. [Conclusion]The significance of this study is that all the experiments were conducted without controlling researchsubjects`` daily lives, and it is suggested that the vinegar may be recommended as a kind of health supplement food to suppressobesity. Especially, since these two products are traditional foods of Korean people, which have been taken for ages, it is expectedthat the fusing of two foods may be better applied to ordinary people who are concerned about obesity.

Antioxidant and antiapoptotic effects of pine needle powder ingestion and endurancetraining in high cholesterol-fed rats. JENB., Vol. 18, No. 3, pp.301-309, 2014 [Purpose]Pine needle is a kind of medicinal plantingested traditionally for a variety of purposes. Therefore, we examined the antioxidant and antiapoptotic capacities of pine needle ingestion in high cholesterol-fed and endurance exercise-trained rats. [Methods]Animals were divided into six groups as; CON: normal diet control group; EX: normal diet and exercise training group; HC: high cholesterol diet group; HCE: high cholesterol diet and exercise training group; HCP: high cholesterol and pine needle group; HCPE: high-cholesterol and pine needle diet with exercise training group, respectively. Each group consisted of seven Sprague-Dawley male rats. The swim-training groups, EX,HCE, and HCPE swam in the swim pool 60 min/d and 5 d/week for 5 weeks. During the rearing periods, freeze-dried pineneedle powder mix with 5% of the high cholesterol diet was supplied to the HCP and HCPE groups. Gastrocnemius musclewas used as the skeletal muscle. Malondialdehyde (MDA), Mn-containing superoxide dismutase (Mn-SOD), Cu, Zn containing superoxide dismutase (Cu,Zn-SOD), and glutathione peroxidase (GPx) were analyzed for their antioxidant capacities. Finally, p53,Bcl-2 (B-cell lymphoma 2), caspase-3 protein expression was analyzed to determine antiapoptotic ability. [Results]MDA showed low content in HCPE compared to the HC. Mn-SOD, Cu, Zn-SOD, and GPx protein expression was significantly increased by pine needle ingestion and/or exercise training. In addition, suppression of p53 protein expression resulted in Bcl-2 increase followed by caspase-3 decrease with/without pine needle ingestion and exercise training. [Conclusion]When exercise training in addition to pine needle powder ingestion may be a helpful nutritional regimen to athletes and exercisers.
