Objective: To examine the anti-hyperglycemic effects of aqueous Lenzites betulina(L. betulina) extracts on normoglycemic glucose-loaded ***: Different doses of aqueous extract from L. betulina were administered to 45 ICR mice(Mus musculus) to determine whether there was an effect of L. betulina extracts on the blood glucose level of the ICR mice. Aqueous extracts of L. betulina were orally gavaged to mice using oral glucose tolerance test. A total of five groups were used to determine the effect of the fungi on blood glucose of the mice. Group A(positive control)was given 16.7 mg/kg glimepiride; Group B(negative control) was given distilled water;Group C(low dosage) was given 200 mg/kg aqueous extract; Group D(mid dosage) was given 400 mg/kg aqueous extract and Group E(high dosage) was given 800 mg/kg aqueous extract. Baseline blood glucose value was firstly acquired before induction of hyperglycemia through D-glucose, after which another check on blood glucose was made after 0.5 h. Immediately, after the acquisition of hyperglycemic blood glucose level, the individual administration of treatments were done. After that, three blood collections were done spanning 3 h with 1 h ***: The low dose(200 mg/kg) and the mid dose(400 mg/kg) of L. betulina extracts were significantly different(P 0.05) from its corresponding baseline value, acting faster than the positive control(glimepiride), which only became significantly different(P < 0.05) at the 2nd ***: Aqueous L. betulina extract is able to produce hypoglycemic effects on the mice with all doses, which are able to normalize blood glucose levels at varying times.

Hericium erinaceus(H. erinaceus) is one of the widely used edible mushrooms around the world, primarily in Asian countries. H. erinaceus is used in traditional medicines, and mushroom based foods. The fruiting body and mycelia of H. erinaceus are extracted using the solvents, and several bioactive compounds were identified. Several studies have reported that those bioactive compounds exhibit many health benefits such as hemagglutinating, antimicrobial, immunomodulatory, antitumor, antioxidant, and anti-aging activities, etc. This manuscript consciously updated the information about the composition of H. erinaceus, H. erinaceus based foods, and anti-hyperglycemic property of H. erinaceus.

Based on a non-competitive and selective PTP1 B inhibitor reported by us previously, thirtynine benzamido derivatives were designed and synthesized as novel PTP1 B inhibitors. Among them,twelve compounds exhibited IC_(50) values at micromolar level against human recombinant PTP1 B, and most of them exhibited significant selectivity to PTP1 B over TC-PTP and CD45. Further evaluation of the most potent compound 27 on high-fat diet(HFD)-induced insulin-resistant(IR) obese mice indicated that27 could modulate glucose metabolism and ameliorate dyslipidemia simultaneously.& 2018 Chinese Pharmaceutical Association and Institute of Materia Medica, Chinese Academy of Medical Sciences.

Journal of Food Science and Engineering 2016年第1期6卷 26-31页

Lagenaria siceraria （Molina） Standl., known as bottle gourd is widely available throughout Vietnam as an edible vegetable. Bottle gourd is a commonly fruit but there are little reports about its biological activities. The aim of the present study was to evaluate antioxidant activity and anti-hyperglycemic potential of ethanolic extract of bottle gourd. The ethanolic extract was tested for its antioxidant activity on chelating power, the ferric reducing/antioxidant power assay （FRAP） and the 1, 1-diphenyl-2-picryl-hydrazyl （DPPH） free radical scavenging assay. The results showed that chelating activity was 80.02%, FRAP value was 92.84 μmol Fe^2＋/g and active radical scavenging which showed an IC50 was 49.50 μg/ml. The five different doses of ethanolic extract were treated by oral tolerance to mice body before oral glucose tolerance and blood glucose level was measured using glucose oxidase method. The result indicated that inhibition percentage of ethanolic extract of bottle gourd at the dose of 400 mg/kg in glucose-induced hyperglycemic mice was effectively similar to standard drug glibenclamide. The results obtained indicate that ethanolic extract from bottle gourd is the potential antioxidant and anti-hyperglycemic agent.

Diabetes mellitus is a predominant chronic disease which causes mortality of millions of people yearly. Its prevalence is on the rise worldwide. Water kefir is fermented food produced by a matrix of polysaccharides containing bacteria and yeasts, with therapeutic properties. Our study aimed to evaluate anti-hyperglycemic and anti-hyperlipidemic activities of water kefir on streptozotocin-induced diabetic Wistar rats. Adult Wistar rats were made diabetic by intraperitoneal injection of streptozotocin, and were given or not kefir in drinking water for 5 weeks. Body weight, glucose and lipid levels were measured. The results demonstrated evident improvement in body weight, glucose, and lipid profiles of treated rats comparing with diabetic or control rats. Water kefir is found to be less cost hypoglycemic and hypolipidimic treatment and less time consuming. Water kefir can potentially be useful food for diabetes to control glucose and lipid levels.

Effects of Bofutsushosan and Gardeniae Fructus on Diabetic Serum Parameters in Streptozotocin-Induced Diabetic Mice

引用

Chinese Medicine 2011年第4期2卷 130-137页

作者： Qing Yu Mai Yasuda Tatsuo Takahashi Masaaki Nomura Nobuyoshi Hagino Shinjiro Kobayashi 不详

Streptozotocin (STZ)-induced diabetic mice increased levels of serum glucose, triglyceride and cholesterol, and decreased level of serum insulin. Effects of Bofutsushosan (BOF: Pulvis ledebouriellae compositae: 防風通聖散) and its composed crude drug, gardeniae fructus (GF: 山梔子) were investigated on levels of these diabetic parameters (serum glucose, insulin, triglyceride and cholesterol) in STZ-diabetic mice. BOF and GF were extracted in 10 volumes of distilled water with an automatic extractor “Torobi”. STZ-induced diabetic mice with serum glucose level of over 600 mg/dl at 3 - 4 weeks after intravenous injection of 150 mg/kg STZ were used for experiments. BOF extract, GF extract, geniposide (a main constituent of GF), and glibenclamide were administered intraperitoneally into 3-hour-fasted STZ-diabetic mice. At 6 hours after administration, BOF extract (100 - 300 mg/kg) decreased high levels of serum glucose, triglyceride and cholesterol, and also increased low level of serum insulin in STZ-diabetic mice in a dose-dependent manner, respectively. anti-diabetic drug glibenclamide (0.3 - 1 mg/kg) as positive control significantly decreased serum glucose and cholesterol levels, and increased serum insulin level in the diabetic mice. GF extract (30 - 300 mg/kg) decreased serum glucose, triglyceride and cholesterol levels but did not affect serum insulin level in the diabetic mice. Geniposide (10 - 100 mg/kg), decreased serum glucose level but did not affect serum insulin and triglyceride levels in the diabetic mice. These results demonstrated that intraperitoneally administrated BOF extract improved abnormal levels of serum glucose, insulin, triglyceride and cholesterol in the STZ-diabetic mice as being similar to glibenclamide. GF extract has an important role in a part of improving actions of BOF in the diabetic mice. The action of GF extract on serum glucose was parallel with the action of geniposide in the diabetic mice, supporting roles of geniposide in anti-hyperglyc
