Background and aim The treatment of diabetic ulcers is difficult because of defective blood vessels and frequent co-occurrence of bacterial infections. In a previous study, we found a water fraction of Merremia mammosa (Lour.) (Mm(Lour.)) had beneficial effects on wound healing in diabetic rats. This study aimed to evaluate the influence of different gelling agents added to Mm(Lour.) water fraction gel on wound healing treatment in diabetic rats. Experimental procedure Diabetic Wistar rats were divided into the following five groups: 1. positive control (Neomycin Sulfate 0.5% and Placenta Extract 10%), 2. negative control (distilled water), and 10% water fraction of Mm(Lour.) extract in 3. HPMC, 4. Carbopol, and 5. CMC Na gelling agents. The wound was made by the Morton method and treatment applied every other day for 25 days, then the wound healing process was observed. Data were observed and analysed using appropriate statistic tools. Results Histopathology observation, VEGF expression and hydroxyproline levels showed a significant acceleration of wound healing in all treatment groups compared to the negative control group. This study showed all of Mm(Lour.) gel formulations could restore the delayed healing process on wound in diabetic rats and were equally effective in accelerating wound healing. CMC Na was the most preferable because it did not irritate. Conclusion The results suggest that Mm(Lour.) water fraction in CMC Na gelling agent provided an option to be developed as a topical drug on diabetic wound healing treatment, showed by enhancement of collagen synthesis and angiogenesis.
High-protein, low-carbohydrate diets deteriorated diabetic conditions and were associated with insufficient insulin secretion in db mice. Our findings may have implications for dietary management of diabetic symptoms in human patients.
Objective: This research aimed to evaluate the effect of fractionation of Merremia mammosa Lour. (Mm (Lour.)) extract on diabetic wound healing by observing collagen synthesis process and to search the most potent fraction.Methods: Wistar rats were divided into five groups (n=5), i.e., K-(negative control), K+ (positive control), K1 (ethyl acetate fraction), K2 (water fraction), and K3 (n-hexane fraction). The Mm (Lour.) was extracted with ethanol 70%, then fractionated by using three solvents which have different polarity. The rats were adapted in 7 days, then induced into diabetic by streptozotocin dose 40mg/kg body weight. The wound was made by Morton excision method. Treatment was given every two days and skin biopsy was done on day 11. Analysis of collagen density was done by photomicrograph of histopathology preparations in Masson’s trichome stained by using trinocular microscope with 400x magnification in 6 fields of view, then processed by imageJ software and analyzed by appropriate statistic tool.Result: The results of this research showed that fractionation of Mm (Lour.) extract significantly enhanced diabetic wound healing based on macroscopic (percentage of wound healing) and collagen density with p-value<0.05 when compared with negative control, especially the water fraction (p=0.000). The follow up post hoc analysis showed that there was no significant (p=0.989) or there was no meaningful difference in the group of water fraction when compared to positive control.Conclusion: Water fraction is the extract fraction of Mm (Lour.) which has the most significant influence on diabetic wound healing showed by enhancement of collagen synthesis.
Nutrition status in the first thousand days of life (FTDL) of 270 days during pregnancy and 730 days in the infant's first life is a critical period, since the resulting consequences are permanent and irreparable. There are still many problems in the group of FTDL around the campus of University of Jember which require intensive handling, such as stunting, low energy protein, anemia, underweight and etc. Methods of improving the quality of nutrition for the FTDL group can be done by increasing knowledge about nutrition through counseling by utilizing various media (posters, brochures, videos, demos and presentation slides). This study aims to determine how far is the effectiveness of nutrition counseling in improving knowledge and attitude awareness on nutrition problems. The method used was to give counselling on nutrition in the target groups (members of Posyandu Catleya A and B) and assessed changes by comparing the level of nutritional knowledge and attitude before and after receiving counseling. The results showed there were significant differences in the level of nutritional knowledge and attitude between before and after the counseling about nutrition and food processing technology. It can be concluded that this method is quite effective to raise awareness of FTDL group on nutrition problems. Keywords: food insecurity, nutrition counseling, nutrition awareness
Objectives Exercise is effective for preventing the onset and development of type 2 diabetes mellitus (T2DM) in human cases; however, the effect of exercise on the pathophysiology using animal models of T2DM has not been fully evaluated. Methods We applied voluntary exercise under pair-fed (P) conditions in db mice, an animal model of T2DM. Exercising (Ex) and sedentary (Se) mice were placed in a cage, equipped with a free or locked running wheel, for 4 weeks, respectively. The amount of food consumed by ad libitum-fed wild-type mice under the Se condition (ad-WT) was supplied to all mice, except ad libitum db mice (ad-db). Blood parameters and expression of the genes involved in nutrient metabolism were analyzed. Results PEx-db (pair-fed and exercising) mice showed significantly lower HbA1c, body weight and liver weight than PSe-db and ad-db mice. Decreased hepatic triglycerides in PEx-db mice corresponded to a lower expression of lipogenic enzyme genes in the liver. Moreover, PEx-db mice showed significantly lower plasma branched-chain amino acids (BCAA), arginine, proline, and tyrosine, in addition to increased skeletal muscle (SM) weight, than PSe-db and ad-db mice, in spite of little influence on the expression of the BCAA transaminase gene, in SM and WAT. Conclusion We found that exercise under a food restriction condition decreases several amino acids, including BCAA, and may improve insulin sensitivity more than mere food restriction. We propose that the decreased concentration of blood amino acids may be a valuable marker evaluating the effects of exercise on diabetic conditions.
