Objectives: This study investigated the effects of water extract of Coix lacrymajobi var. mayuen on obesity and its associated factors in high fat diet (HFD) induced obese mice. Methods: Male C5BL/6 mice were randomly assigned to 4 groups, normal group (chow diet), a HFD, HFD with water extract of Coix lacrymajobi var. mayuen 100 mg/kg (W-Coix), and HFD with phentermine 5 mg/kg (Phen) as positive control. Body weight, food intake, fasting blood glucose were checked every week and then organs, blood serums were collected after 16 weeks of treatment. Results: Body weight and adipocyte size were significantly lesser in W-Coix than in HFD group; however energy efficiency in W-Coix were not different with HFD. The oral glucose tolerance test, serum glucose and insulin were significantly decreased in W-Coix, also lipid accumulations in liver tissue and lipid levels (total cholesterol, high density lipoprotein-cholesterol) were improved with W-Coix treatment. However skeletal muscle loss with HFD was not changed in W-Coix compared with HFD group. Conclusions: The W-Coix treatment decreased body weight, adipocyte size and it is associated with improved glucose and lipid metabolism. Further studies are needed to know the mechanism of antiobesity in W-Coix.

To evaluate the effect of low lactose special formula (MF-1) for the treatment of acute diarrhea, we studied thirty nine infants who were admitted with acute diarrhea to the Department of Pediatics, Yeungnam University Hospital. 39 infants of under 6 months of age who had been fed on formula feeds were randomly allocated to receive either a diluted regular formula milk or a low lactose special formula. Each infant received intravenous rehydration during fasting for 6-12 hours. Group 1 (n=15) was fed half strength of regular formula (80-100cc/kg/day) for the first 24 hours, three quarters strength formula (100-120cc/kg/day) for the next 24 hours, and continued feeding with the full strength regular formula milk. Group 2 (n=24), who fed the same amount of milk as Group 1, continued feeding with the full strength low lactose special formula from the start of feeding. Male to female sex ratio was 1.6 to 1. The characteristics of infants on admission were comparable in the age, the duration of diarrhea and the stool frequency before admission, the degree of dehydration. There were no significant differences in the duration of hospitalization, changes in stool weight and stool frequency after admission between two groups.(p>0.05) The Body weight and skin fold thickness were increased in group 2 who fed low lactose formula, but those who fed diluted regular formula showed reduction of body weight and skin fold thickness ($64.2{\pm}51.4g$ vs $-11.4{\pm}52.2g$, $0.6{\pm}0.8mm$ vs $-0.1{\pm}0.3mm$ respectively) during hospitalization. (p<0.05) We conclude that low lactose special formula milk can be recommended instead of diluted regular formula for acute diarrhea treatment in infants.

We investigated the hypoglycemic effect of formula containing Euonymus alatus (EA) and Mori Folium (MF) in multiple low dose (MLD) streptozotocin (STZ)-induced diabetic rats. In order to iduce hyperglycemic state 25 mg/kg of STZ was injected intraperitoneally for 5 consecutive days. SD rats were randomly divided into diabetic control and treatment groups. Treatment groups were administered with either 250 mg/kg of EA and 250 mg/kg of MF (E1Ml), or 500 mg/kg of EA mixed with same dose of MF (E2M2) for 3 weeks. Blood glucose levels and body weights were measured every 5th or 6th day. E1Ml and E2M2 both significantly reduced food intake, water intake, and fasting blood and urine glucose levels as compared to those in diabetic control group in a dose dependent manner. Body weight in diabetic control group was increased slightly after 3 weeks. Treatment group, however, showed gradual increase in body weights during 3 week-period. While plasma insulin levels of the diabetic control group were decreased to the level of 387$\pm$14 pg/ml from 534$\pm$36 pg/ml, those levels in E1Ml and E2M2-treated groups were both markedly increased by 13% and 26%, respectively. Urine glucose levels in E1Ml and E2M2-treated groups were also remarkably reduced by 17 and 26% compared to the levels of diabetic control group. While expression of membrane-bound glucose transporter-4 (GLUT-4) protein in skeletal muscle was reduced by 45% in diabetic control compared to the normal control, GLUT-4 protein expressions in E1Ml and E2M2-treated groups were augmented by 2 and 3.5 times compared to the diabetic control, respectively. Pancreatic HE staining experiments showed that E2M2-treated group revealed much less infiltrated mononuclear cells, indicating that E2M2 efficiently blocked insulitis induced by multiple low dose streptozotocin. Taken together, we conclude that formula containing EA and MF may prevent or delay the development of hyperglycemia through overexpression of GLUT-4 protein in skeletal muscle and prevention of insulitis.

Type 2 diabetes mellitus relavant to insulin resistance is a chronic and hard to control. In order to develop an antidiabetic agent from natural products, anti-hyperglycemic effect of herbal formula containing Mori Follium, Euonymi Lignum Suberalatum and Ginseng Radix(MEG) was investigated in db/db mice. Treatment group was administered orally with MEG formula at a dose of 300 mg/kg for 5 weeks, and blood glucose, insulin and lipid levels were determined. MEG treatment group showed a marked decrease in fasting blood glucose level and insulin resistance index(IRI) compared to those in diabetic control. Improvement of insulin resistance(60.6%) was indicative of reducing lipid levels in plasma and triglyceride contents in muscle and adipose tissue. In addition, expressions of an insulin responsive gene, glucose transporter 4(Glut4), in muscle and adipose tissue were upregulated in MEG treatment group. Compared islet morphology between groups, MEG formula prevented the ${\beta}$-cell destruction caused by high blood glucose. Taken together, MEG formula can act as an anti-hyperglycemic agent with insulin sensitizing effect, and thus deserves a clinical trial in the future.

mechanisms for the hypocholesterolemic effects of $\beta$-glucan remain unclear. Rats were divided into 3 groups ; normal control group, atherogenic group(oral administration of cholesterol 40 mg/kg/day plus vit. $D_2$ 320,000 IU/kg/day), $\beta$-glucan treatment group(atherogenic treatment plus $\beta$-glucan 0.135 g/kg/day). The $\beta$-glucan treatment group showed moderate increases of serum lipids concentration compared with atherogenic group. In histopathological examination, aortas showed no critical lesions. The total fecal neutral sterols and bile acids excreted for 6 days was increased compared with both normal and atherogenic group. To compare effects of soluble fiber and insoluble fiber extracted from barley on postprandial lipemia, 5 healthy male adults ingested on separate days a low-fiber(total dietary fiber 2.61g) control meal or dietary fiber-enriched(12.61g) meals. Fasting and postprandial blood samples were obtained for 6.5h and serum lipids were analyzed. The serum total lipids, total cholesterols, LDL & VLDL-cholesterol were markedly reduced with soluble fiber-enriched meals, but no decrease with insoluble fiber-enriched meals. These results suggest that mechanisms for the hypocholesterolemic effect of $\beta$-glucan on rats were due to the inhibition of cholesterol absorption in the intestinal lumen and acceleration of cholesterol catabolism in the liver. And the soluble dietary fiber($\beta$-glucan) has the hypocholesterolemic effect by dropping serum LDL & VLDL-cholesterol in the clinical study.

Chronic treatment with olanzapine (OLZ), an atypical antipsychotic drug, is associated with the adverse effects of weight gain, hyperglycemia and/or hypertriglyceridemia. Green tea or epigallocatechin gallate (EGCG), one of the most abundant green tea polyphenols, significantly reduces or prevents an increase in glucose levels, lipid markers and/or body weight. We hypothesized that combined treatment with OLZ and green tea extract (GTE) or EGCG may prevent body weight gain and increase of the lipid markers. ICR male mice weighing an average of 30.51 g (n=32) at the beginning of the experiment were used. OLZ, OLZ+GTE and OLZ+EGCG were administered for 27 d in the drinking water, and then the levels of fasting glucose, nitric oxide (NO), and a typical lipid marker triglyceride (TG) were determined in plasma. The body weight and food intake were also compared. The chronic treatment of OLZ increased the average body weight compared with that of controls. In the presence of GTE or EGCG, the OLZ-induced increase in body weight was significantly prevented. Furthermore, in the OLZ group, the plasma levels of glucose, NO and TG were significantly increased, whereas GTE or EGCG prevented these increases. These results implicate that OLZ may induce systematic inflammatory reaction, and suggest that GTE or EGCG can protect against OLZinduced weight gain, hyperglycemia and hypertriglyceridemia.

Objectives : The purpose of this study is to assess the effect of using Boyanghwano-tang(BYHWT) for diabetic retinopathy. Methods : We searched randomized controlled trials(RCTs) that used BYHWT for diabetic retinopathy in 10 databases(RISS, KISS, ScienceON, KCI, OASIS, DBpia, CNKI, Wanfang Database, PubMed, Cochrane Library) on August 12, 2023. Outcome measurements included total effective rate(TER) and visual acuity as the primary outcome measurements, and the secondary outcome measurements included fasting blood glucose(FBG), 2hPG, HbA1c, ET-1, NO, etc. The indicator of stability included adverse reactions. A meta-analysis was conducted according to TER, visual acuity, FBG. Results : A total of 8 randomized control trials were selected. The treatment group which used BYHWT showed significant improvement effects in TER and visual acuity compared to the control group which used western medicine or chinese patent medicine alone. TER: (RR: 1.22, CI 1.14 to 1.31, P=<0.00001), visual acuity: (RR: 2.06, CI 1.40 to 3.03, P=0.0002). Secondary outcome measurements including FBG also showed improvement in the treatment group compared to the control group. FBG: (MD: -0.15, CI -0.43 to 0.31, P=0.28). Adverse reactions were only mentioned in one study, which showed that no adverse reactions occurred in both the treatment and control groups. Conclusions : This study suggests that BYHWT is effective for diabetic retinopathy. However these findings should be interpreted cautiously due to the insufficient number of studies and unknown or high risk of bias in the included trials.

This study evaluated the effects of preslaughter feed withdrawal and chiller ageing on objective meat quality traits in longissimus dorsi (LD), biceps femoris(BF), and triceps brachii(TB) muscles of Korean native black pigs. Twenty males were assigned into a 2(pre-slaughter feeding) ${\times}$ 2(pre-slaughter stress) ${\times}$ 4(chiller ageing) factorial. Pre-slaughter fasting for 18 h resulted in significantly(P < 0.05) higher pHs at 1.5 h for both LD and BF. On the other hand, muscle temperature did not differ between the fasted and fed animals. The result implied that pigs with different pre-slaughter feedings experienced different pH-temperature profiles during rigor development. This was reflected by the significan(P < 0.05) increase in cooking loss and hunter $L^*$ for LD of the fed pigs. However, WB-shear force of LD was not affected by the treatment. Furthermore, objective meat quality of BF and TB did not differ between the treatments. Hunter $L^*$ value and cooking loss for LD were constant for 7 d, followed by a significant(P < 0.05) increase at 14 d. BF and TB had significantly(P < 0.05) higher hunter $L^*$ value and cooking loss at 14 d than at 1 d. Significant(P < 0.05) linear reductions in LD WB-shear force took place from 1 to 7 d, while BF and TB WB-shear forces were significantly (P < 0.05) reduced at 14 d. Simple correlation for WB-shear force between LD and BF, and between LD and TB indicated that 6 kg of shear force for LD was equivalent to approximately 3.5 and 6 kg for TB and BF, respectively. On the basis of the current result, feeding until the morning of slaughter appeared to contribute to favourable meat color for LD. However, negative effect on palatability due to increase in cooking loss should be taken into account. A 7-d chiller ageing was likely the best practice for LD, while TB appeared not to require chiller ageing. A 14-d ageing could improve the tenderness of BF, but could likely reduce juiciness.

Objectives: This study aimed to identify the current use of Korean medicine for obesity and its effect for women in climacteric period. Methods: We studied women aged 45-55 who visited Daejeon Korean medicine Hospital of Daejeon University to lose body weight from January 1, 2021 to December 31, 2022 via an analysis of the medical records. The treatment duration was continuous for more than 2 weeks, and a body composition was measured by Inbody 770 at 2 to 4 weeks after the first visit. Results: 28 patients were finally selected and their average age was 49.32±3.38 years. Based on the body mass index (BMI) classification, 19 were in the 1st obesity group, 5 in the 2nd obesity group, 3 in the overweight group and 1 in the normal group. Patients usually complained comcomitant symptoms, and the symptoms of menopausal disorder was the most frequent. The average treatment duration was 3.68±0.67 weeks and the average treatment frequency was 3.93±0.98 times. All patients took herbal medicines Gambi-tang and 23 took modified fasting therapy including Gamro-su. 14 were treated by whole body far-infrared therapy and 6 were gotten partial obesity treatment. Among patients treated for accompanying symptoms, menopausal disorders were the most common (35.71%), and herbal medicine such as Gamisoyou-san, Hominis Placenta Pharmacopuncture, moxibustion, and cupping were used. After treatment, on average, body composition changed significantly; body weight 3.28±1.82 kg, BMI 1.36±1.04 kg/m², body fat 1.70±1.67 kg, skeletal muscle mass 0.81±0.91 kg, abdominal circumference 2.04±2.6 cm, and visceral fat area 8.91±12.83 cm². Conclusions: We analyzed general characteristics, BMI distribution, types of Korean medicine treatment and change of body composition. This study could be used as reference to provide practical data of treatment for obese women in climacteric period.

Animal welfare advocates, claim that the induced molting by fasting be avoided. This study was conducted to evaluate the effect of molting induced by various feeding methods on productivity and egg quality in laying hens. We used 400 flocks of 60-week-old leghorn laying hens in four treatments(five replicates of 20 hens each): fasting method (C), feeding single corn grain diet (T1), feeding single wheat bran diet (T2) and feeding single alfalfa meal diet (T3). As the result of the experiment, egg production and daily egg mass significantly decreased only in T1 compared with the control during the $1{\sim}4th$ week after the secondary egg laying (P<0.05). Although the amount of feed intake was significantly less in T1 group during the $1{\sim}4th$ week compared to the control, no significant difference was detected during the total period (P>0.05). In addition, no significant difference of feed conversion was observed between treatment groups. In terms of egg quality, the egg shell thickness was significantly improved in T1 group than the control group by feeding only corn at the 10th and 14th week after the secondary egg laying (P<0.05), but the significant decrease was observed at the corn (T1) and wheat bran (T2) fed treatment groups than the control group at the 26th week of the experiment (P<0.05). The eggshell strength and haugh unit did not show any difference by the molting methods. Egg yolk color was significantly decreased in T1 and T2 group than the control group at the 6th week (P<0.05). However, T1 and T2 group resulted to show significantly high egg yolk color at the 18th week of the experiment (P<0.05). As the result of the experiment, no large difference was observed in the productivity by the feeding molting method and by the fasting induced molting method. In addition, the single diet fed feeding induced molting method by using alfalfa revealed to show more satisfactory trend than the corn or wheat bran single diet fed feeding induced molting methods even if no statistically significant difference was found in terms of egg productivity.
