The aim of the present study was to analyze the effect of polycan, a β-glucan originating from Aureobasidium, on high-fat diet (HFD)-induced hyperlipemia and hepatic damage. A total of 30 hamsters were divided into 6 groups based on their body weight following acclimatization: control, sham, simvastatin (SIMVA) and 3 Polycan groups. In the polycan groups, Polycan, at three concentrations (31.25, 62.5 and 125 mg/kg), was administered orally once a day for 56 days, in addition to the HFD. On the day of sacrifice, changes in the body weight, food consumption, liver weight and serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglyceride and total cholesterol (T-CHOL) were observed, as well as changes to the liver and aorta (thoracic and abdominal) histopathology and histomorphometry. The results from the polycan groups were compared with a SIMVA 10 mg/kg oral treatment group, in addition to the sham and vehicle control groups. After the HFD-induced hyperlipidemic hamsters were administered Polycan, there was no significant change in their body weight and food consumption when compared with the hamsters in the vehicle control group. However, the serum levels of AST, ALT, triglyceride, T-CHOL and LDL were significantly reduced in a dose-dependent manner when compared with the vehicle control group (P<0.05). Furthermore, the levels of liver steatosis and arteriosclerosis in the abdominal and thoracic aorta were significantly decreased in a dose-dependent manner (P<0.01). In the SIMVA-treated group, body weight (P<0.05), the serum level of lipids (triglyceride, T-CHOL and LDL; P<0.01) and the level of arteriosclerosis (P<0.01) were significantly reduced when compared with the vehicle control group. However, liver weight and the serum levels of AST, ALT, and liver steatosis increased when compared with the vehicle control group. Based on these results, it was concluded that polycan exerts a favorable effect in decreasing HFD-induced hyperlipemia and associated atherosclerosis, with relatively good protective effects on liver damage. © 2015, Spandidos Publications.

Constipation is a common problem in males and females. The aim of the present study was to evaluate the laxative effects of fermented rice extract (FRe) on rats with loperamide-induced constipation. FRe (100, 200 and 300 mg/kg) was administered orally once per day for six days following 1 h loperamide treatment. The laxative effects of FRe were compared with those of sodium picosulfate (S. picosulfate). Following the induction of constipation in the rats, a marked decrease was observed in the fecal pellet number and water content discharged over 24 h, the surface mucus thickness in the colonic lumen, intestinal charcoal transit ratio, thickness of the colonic mucosa and the number of mucus-producing cells, while an increase was observed in the number of fecal pellets remaining in the colonic lumen and their mean diameter, as compared with the normal vehicle control rats. These conditions were significantly alleviated following the administration of the three doses of FRe when compared with the loperamide control group. However, the alleviating effects were lower than those of S. picosulfate, with the exception of the intestinal charcoal transit ratio. Similar effects on the intestinal charcoal transit ratio were detected for the three doses of FRe when compared with the S. picosulfate-treated rats. In conclusion, the results indicated that FRe exhibits a laxative effect without causing diarrhea, as compared with sodium picosulfate; thus, FRe may be effective as a complementary medicine in patients suffering from lifestyle-induced constipation. © 2014, Spandidos Publications.

Polycalcium is a mixture of Polycan and calcium lactate-gluconate 1:9 (w/w) with demonstrated antiosteoporosis activity in vitro and in vivo studies. These studies were a 4-week open-label, single-center trial to evaluate the efficacy of oral Polycalcium on bone metabolism and safety. In total, 30 healthy women (range 40-60 years) were administered 400 mg of Polycalcium for 4 weeks. The primary efficacy parameter was urinary deoxypyridinoline (DPYR) levels, and serum osteocalcin (OSC), bone-specific alkaline phosphatase (BALP), urinary cross-linked C-telopeptide of type-1 collagen (CTx), urinary cross-linked N-telopeptide of type-1 collagen (NTx), calcium (Ca), and phosphorus (P) levels, which were evaluated for comparison before and after administration of Polycalcium. After 4 weeks of Polycalcium administration, 27 subjects completed the test plan. Three subjects withdrew their consent to participate. The values of blood OSC, BALP, serum Ca, and serum P from baseline to 4 weeks of treatment were changed by -28.44%, 14.37%, 6.11%, and 1.42%, respectively. Biomarkers of bone resorption: urinary DPYR, serum CTx, serum NTx, urinary Ca, and urinary P, at baseline after 4 weeks of treatment were changed by -13.40%, 6.67%, -5.13%, -22.43%, and -3.04%, respectively. Additionally, when considering the subjects' adverse effects and the results of the blood and urine tests over the 4-week trial period, the dose of 400 mg Polycalcium showed efficacy for improving bone metabolism and was well tolerated and safe. Polycalcium was apparently safe and efficacious. © Mary Ann Liebert, Inc. and Korean Society of Food Science and Nutrition.

The aim of present research was to determine the acute oral toxicity of fermented rice extracts (FREs), in female and male ICR mice. To investigate the toxicity and identify target organs, FREs were orally administered once to male and female ICR mice at doses of 0 (vehicle control), 500, 1000, or 2000 mg/kg body weight (BW). Effects on mortality, BW, and clinical signs were monitored over 14 days, including changes in the weights and histopathological characteristics of 14 organs, as described in the Korea Food and Drug Administration (KFDA) Guidelines (2009-116, 2009). No treatment-related mortality was observed during the 14-day observation period in either gender. In addition, no FRE-related change was observed in BW or organ weight (OW), clinical indicators, or histopathological findings in this study. Our results suggest that the FRE is non-toxic in mice and is therefore likely to be safe for clinical use. The approximate LD and LD50 in mice after single oral dose of FRE are greater than 2000 mg/kg in female and male ICR mice. Additionally, no specific target organ or negative clinical indicator was detected in this study.

The antiobese effects of Allium victorialis (AV) leaf methanol extract were evaluated in a high fat diet (HFD) supplied mice. The changes on the body weight, food consumption, leptin and adiponectin levels as well as the periovarian fat weights and histopathology of adipocytes were examined. The effects were compared with those of a group given 250 mg/kg of metformin. After 91 days of a continuous HFD supply, the mice were significantly showed obesity. However, the obesity induced by the HFD was inhibited by the AV extract treatment at the three different doses (62.5, 125 and 250 mg/kg) respectively. The results suggest that the AV methanol extract is beneficial for improving the diet-induced obesity in humans.

The present study aimed to investigate the protective effects of Polycan, a β‑glucan from Aureobasidium pullulans SM‑2001, in a rat model of ovariectomy‑induced osteoporosis. Ovariectomized (OVX) rats were orally administered 31.25, 62.5 or 125 mg/kg/day Polycan for 126 days, and alterations in body weight, bone mineral content, bone mineral density, failure load, histological profiles and histomorphometric indices were analyzed. In particular, serum levels of osteocalcin, bone‑specific alkaline phosphatase (bALP), calcium and phosphorus, and the urine deoxypyridinoline/creatinine ratio, were measured. Furthermore, the femur, tibia and lumbar vertebrae were harvested from all rats, and histomorphometrical analyses were conducted in order to assess the mass and structure of the bones, and the rates of bone resorption and formation. One group of rats was treated with alendronate, which served as the reference drug. The results of the present study suggested that Polycan treatment was able to inhibit ovariectomy‑induced alterations in bone resorption and turnover in a dose‑dependent manner. In addition, the serum expression levels of bALP and all histomorphometrical indices for bone formation were markedly increased in the Polycan‑treated groups. These results indicated that Polycan was able to preserve bone mass and strength, and increase the rate of bone formation in OVX rats; thus suggesting that Polycan may be considered a potential effective anti‑osteoporosis agent. © 2016, Spandidos Publications.
