Combination treatment of metformin and red fruit (Pandanus conoideus l.) extract increased pancreatic β cell density but had no effect toward fasting blood glucose and glycated albumin levels in diabetic male wistar rats (Rattus norvegicus)

Background: Diabetes mellitus (DM) is a degenerative disease associated with premature aging characterized by hyperglycemia. Hyperglycemia in people with DM causes oxidative stress and increases Glycated Albumin level, which is the initial precursor to the formation of AGEs. In turn, AGEs will lead to pancreatic β cell damage and apoptosis. Red fruit (Pandanus conoideus L) contains phytochemicals with antioxidant that has the potential to reduce diabetic complications. Therefore, this study aimed to evaluate the effect of metformin and red fruit extract combination toward blood glucose, glycated albumin and pancreatic β cells density in diabetic rats (Rattus norvegicus). Methods: A post-test only control group study was conducted using 36 male Wistar rats as subject. All subjects were induced for type-2 DM with Streptozotocin and Nicotinamide. The diabetic rats were then divided into 2 groups: the positive control group treated with metformin + placebo and the treatment group treated with metformin + red fruit extract. Pancreatic β cell, fasting blood glucose and glycated albumin assessments were performed after 21 days of treatment. Results: The results showed the mean number of pancreatic β cells in the treatment group was higher than the control group (116.11±33.14 vs 83.20±23.94 cells/visual field; p=0.002). But the mean fasting blood glucose in the treatment group was not significantly different compared to the control group (107.67±14.93 vs. 113.67±11.19 mg/dl; p=0.181). The same result also found in the gycated albumin level (Treatment vs control: 6.97±3.63 vs 6.42±4.01 ng/ml; p=0.666). Conclusion: It can be concluded that the administration of red fruit extract increased the density of pancreatic β cell but did not reduce fasting blood glucose and glycated albumin levels in diabetic Wistar rats.

Administration of Creatine Monohydrate® increased the estrogen levels but have no effect on testosterone levels in male albino rats (rattus norvegicus) with moderate physical activity

Background: Our laboratory assessment indicated that the Creatine Monohydrate® supplement contains phytoestrogen and phytoprogesteron. This study was aimed to prove that the administration of Creatine Monohydrate® supplement could increase the estrogen levels and decrease testosterone levels in male albino rats (Rattus norvegicus) with moderate physical activity given. Methods: A true experimental with pre-test and post-test randomized control study was conducted using 14 albino male rats. The samples were divided into two groups; the control groups (P0) that received aquadest and moderate physical activity, and treatment group (P1) that received 0.4 mg Creatine Monohydrate® supplement twice a day and moderate physical activity given. Moderate physical activity (swimming) was given five times a week for 14 days. Estrogen and testosterone level were assessed before and after treatment was given. Results: Before the treatment, the estrogen and testosterone levels between P0 group and P1 group were comparable. Post-test results showed a significant different in estrogen levels between the P0 and P1 group (23.17±2.86 and 27.82±3.06 ng/ml respectively; p<0.05) as well as testosterone levels (18.15±2.95 and 21.69±2.14 ng/ml respectively; p<0.05) after 14 days of treatment. A paired analysis showed an elevating of estrogen levels but no effect on testosterone levels in P1 group that treated with Creatine Monohydrate® Conclusion: This study indicated that the administration of Creatine Monohydrate® increased the estrogen levels but have no effect on testosterone levels in male albino rats (Rattus norvegicus) with moderate physical activity.

Combination treatment of vildagliptin and bay leaf (Syzygium polyanthum) extract increased pancreatic beta cells number but have no effect toward glycated albumin levels in diabetic male Wistar rats (Rattus norvegicus)

Introduction: Diabetes mellitus is a complex and progressive disease which often lead to several debilitating complications that partly caused by by free radicals which can be overcome with antioxidants. Bay leaves contain essential oils, tannins, flavonoids and terpenoids which have considerable antioxidant properties. Therefore, this study aims to determine the effect combination treatment of vildagliptin and bay leaf (Syzygium polyanthum) extract toward pancreatic beta cells density and glycated albumin levels in diabetic male Wistar rats (Rattus norvegicus). Methods: An experimental posttest only control group study was conducted using 36 albino male rats, aged 2-3 months, weighing 180-200 grams. The rats were divided into 2 groups (n= 18) with control group treated with 1.8mg/200g body weight vildagliptin and 2cc placebo (aquabidest) while the treatment group received 1.8mg/200g BW vildagliptin and 250 mg/200g BW bay leaves extract. All treatment lasted for 21 days. Results: The results showed that pancreatic beta cell counts in the treatment group was significantly higher than the control group (109.07 ± 20.47 cells/field of view vs 90.87 ± 13.91 cells/field of view; p<0.01). However, the levels of Glycated albumin between two groups were not significantly different (treatment vs control: 17.33 ± 4.51 vs 20.18 ± 4.57; p=0.068). Conclusion: This study suggested that combination treatment of vildagliptin and bay leaf extract increased pancreatic beta cells but did not reduce glycated albumin levels in diabetic male Wistar rats.

Macassar fruit extract (Brucea javanica (l.) merr) increased the level of superoxide dismutase (SOD) but had no effect on the level of malondialdehyde (mda) in paraquat-treated male swiss Webster mice

Introduction: Paraquat exposure causes aging because it induces oxidative stress marked by decreased level of SOD and increased MDA serum level. Macassar fruit contains bioactive compounds such as vitamin C, flavonoids, tannins and polyphenol that have antioxidant activity. The purpose of this study was to prove that Macassar fruit extract increased the level of Superoxide Dismutase (SOD) enzyme and reduce the level of Malodialdehid (MDA) in male Swiss Webster mice treated by paraquat. Methods: A randomized pretest-posttest control group study was conducted using 14 male mice which were 2-3 months old, healthy and had 25-30 gram in weight. They divided into 2 groups namely P0 (control) and P1 (Treatment). Both groups were treated by paraquat but only group P1 received 20 mg Macassar fruit extract while the P0 only got 1 cc placebo for 14 days. Results: Our result showed that the level of SOD was increased in P1 group from 17.18±1.69 U/ml to 67.56±3.65 U/ml (p<0.01) while no change was observed in P0 group 16.97 ±1.45U/ml to 17.07±1.89 U/ml (p>0.05). However, no effect on MDA level was observed as the level of MDA tended to slightly decrease in both groups. Conclusion: It can be concluded that Macassar fruit extract 20 mg/kgBB significantly increased the level of SOD whilehave no effect on MDA level in male mice Swiss Webster treated by paraquat.

Oral L-Arginine lower neovascularization and the number of fibroblasts but failed to increase nitric oxide and epithelialization in the healing process of male white diabetic wistar rats (Rattus norvegicus)

Introduction: Oral L-Arginine is a conditional essential amino acid that plays a role in wound healing in DM. The role of arginine in diabetic wounds is by enhancing blood circulation in the injured area and increasing oxygen supply to the wound tissue. The purpose of this study to prove the administration of oral L-Arginine toward vascularization status in wound healing of male white rats wistar diabetes mellitus. Methods: A randomized posttest only control group study using with 36 diabetic induced wistar rats (Rattus Norvegicus) aged 2-3 months and weighing 180-200gram which then divided randomly into two groups. Nitric oxide level was measured on the third day and each group was then further divided into two groups for examination of neovascularization, fibroblasts and epithelialization on the seventh day and on the tenth day. Results: Administration oral L-Arginine failed to induce any significant change in Nitric Oxide level and wound gap closure. On the other hand, the results showed that the mean neovascularization was significantly different between the two groups on the 10th day (Control group vs intervention group: 4.22±1922 vs1.89±1364; p=0.009). In addition, the mean number of fibroblast at the 10th day was also significantly different (Control group vs intervention group: 74.11±28.57 vs 38.11±20.90; p=0.008). Conclusion: In conclusion, oral L-Arginine did not significantly affect nitric oxide and epithelialization while decreased neovascularization and the number of fibroblasts on day tenth in the healing process of male white rats diabetes mellitus
