AbstractThe objective of this study was to test a topical formulation of EPHX2 inhibitor, GSK2256294, in a dermal wound diabetic (db/db) mouse model. Comparisons were made between groups treated with EPHX2 inhibitor, matching vehicle control and a currently approved treatment for diabetic ulcers, becaplermin/Regranex, as a positive control which is highly efficacious in this model. Leptin receptor-deficient (db/db) male mice were sequentially assigned to treatment groups (N=10 per group) based on blood glucose levels and body weight. Mice were given a single 8 mm diameter full thickness wound on the back. Wounds were photographed and traced, and fresh test materials applied periodically with fresh dressing. Of ten mice treated with GSK2256294, three had completely healed wounds at the study conclusion, and 8/10 mice reached at least 50% closure. In the vehicle group, no mice achieved complete closure, and only 6/10 reached at least 50% closure by the study conclusion. Nine of ten wounds achieved complete closure in the positive control group by 21 days. Although the EPHX2 inhibitor results were indicative of efficacy, the single-sided p-value criterion of 0.05 was not met in this study.

Antidiabetic activity of Vernonia amygdalina and its possible synergism with glibenclamide was checked. Forty eight rats were used for the research, for hypoglycermic study of V. amygdalina alone, they were grouped into five of six rats each. Group 1 was the negative control and was administered distilled water orally. Groups 2, 3, and 4 were the treatment groups which received 100, 200 and 300 mg/kg body weight of the V. amygdalina extract respectively orally by intubation. Group 5 was the positive control group which received a known antidiabetic drug, glibenclamide. Diabetes was induced with alloxan. For the synergism study, another 18 rats grouped into 3 of six rats each was used. Both groups of glibenclamide only and glibenclamide plus V. amygdalina extract were dosed for 14 days orally by intubation, thereafter were sacrificed and blood collected from heart for analysis. There were 5 replicates grouped by weight throughout the study and both single and synergistic studies had the same controls. Effect of V. amygdalina extract was checked on blood glucose and its possible synergism with glibenclamide. All results in treatment groups were compared with the normal control at statistical confidence of p<0.05. Result shows that V. amygdalina extract reduced blood glucose level in the test groups as dose of extract increased. Combination of V. amygdalina with glibenclamide demonstrated further deduction in blood glucose levels in the treatment rats groups. Therefore addition of V. amygdalina into glibenclamide increased efficacy in the diabetic rats. The interaction between V. amygdalina and glibenclamide in this work was additive and therefore synergistic.

Abstract Background. The increasing prevalence of depression gives rise to challenges in not only elucidating its diverse causes, but also in finding an effective treatment. One of the factors linked to depression is the imbalance of serotonin, norepinephrine, and dopamine neurotransmitters.  Cinnamon (Cinnamomum burmannii) as one of the world’s wellknown cooking ingredients is believed to be able to regulate the neurotransmitters imbalance with the help of terpenoids and flavonoid polyphenols as one of its content. Objective. This study aims to determine the effectiveness of cinnamon extract as an antidepressant in depressed induced animal model. Methods. An experimental in vivo with pre-post control group design was conducted in twenty five Wistar strain white rats that were divided into 5 treatment groups that received fluoxetine as positive control, aquades, and different dose of cinnamon extracts (50 mg/kgBW, 100 mg/kgBW, and 200 mg/kgBW).  Depression induction method used was 3-minute Tail Suspension Test, done for 14 days. The antidepressant effectiveness test was carried out by calculating the immobility time duration with Forced Swimming Test method and was further analyzed using one-way ANOVA test. Results. One-way ANOVA test results showed that there were differences in the mean duration of immobility time between treatment groups after being given cinnamon extract (p value = 0,000). Groups that were given 100 mg/kgBW cinnamon extract and 200 mg /kgBW showed a p value>0.05 when compared with positive control group receiving Fluoxetine although displayed a similar reduced immobility time. Conclusion. Cinnamon (Cinnamomum burmannii) extract showed a promising potential as an effective antidepressant tested in animal model.     Keywords: cinnamon, extract, depression, immobility time, rat

Abstract Background Diabetes mellitus is a major public health issue related to the irregular metabolism of carbohydrates, protein, and fat. It occurs due to insufficient insulin production and insulin action. Cucumis melo possesses several biological properties including antioxidant, anti-inflammatory, antibacterial, antihypothyroidism, and antiangiogenic activities. The objective of the present study was to determine the antidiabetic and antihyperlipidemic activities of Cucumis melo var. momordica fruit extract on experimental animals. Result Results show that treatment with C. melo fruit extract and fraction caused a reduction in blood glucose levels. Cucumis melo toluene fraction (CMTF) exhibited a significant (*P < 0.05) reduction of blood glucose level on the 28th day, i.e., 122 mg/dL, in comparison with the positive control group (streptozotocin (STZ)). However, the extract of C. melo showed less significant results in comparison with CMTF. Triglyceride, LDL, and VLDL levels were increased chronically due to STZ and were significantly (*P < 0.05) restored to 84.16, 86.97, and 19.73, respectively, by CMTF in comparison with the positive control group (STZ in the dose of 55 mg/kg). The extract-treated groups also showed similar results as CMTF, but their efficacy was lesser than CMTF. Conclusion It is can be concluded that C. melo fruits can be used as an effective antidiabetic and antihyperlipidemic drug. Graphical abstract

Contaminated water often affects the occurrence of periodontitis in the coastal area. The diabetic hypercholesterolemia-induced periodontitis in Indonesia is very high. The use of coenzyme Q10 to treat this disease has never been investigated yet. Therefore, this study aimedto analyze the effect of coenzyme Q10 on the lipid profile of diabetic hypercholesterolemia-induced periodontitis.Twenty four rats were randomized into 6 groups (G1-G6). The groups (G1-G3) are healthy, negative and positive control group respectively. The treatment groups (G4-G6) are diabetic hypercholesterolemia-induced rats given coenzyme q10 dose of 13,5; 27 and 54 mg/kg respectively. Rats were induced by periodontitis, hypercholesterolemia and diabetes mellitus. Coenzyme Q10 was administered orally using 2 mL gastric tube once a day for 14 days. Lipid profile including triglycerides, HDL, and atherogenic index (IA) was measured enzymatically by the CHOD-PAP method. Data were analyzed by one-way ANOVA test and followed by the Least Significant Difference (LSD) post hoc test.Coenzyme Q10 with a dose of 54 mg/kgis effective in lowering triglyceride, and atherogenic index and increasing HDL level in diabetic hyperlipidemia-induced periodontitis rats model. This research supports the potential effects of coenzyme Q10 supplementation to improve lipid profile in diabetic hypercholesterolemia-induced periodontitis in the coastal area.

<p class="Abstract">In this study the antidiarrheal activity of ethanolic extracts of the leaves of <em>Mikania cordata</em> and <em>Litsea monopetala</em> was evaluated. Diarrhea was induced in mice by oral administration of castor oil (0.5 mL) 30 min after the administration of the extracts. During a 4 hour study the number of diarrheal feces and percentage inhibition of the extracts (200 and 400 mg/kg body weight) was determined. Loperamide (3 mg/kg body weight) served as standard and belonged to the positive control group. The extracts exhibited potent antidiarrheal activity as well as achieved statistically significant p value (p&lt;0.01 and p&lt;0.05) compared to control group. Among the extracts the highest percentage inhibition of defecation (60%) was recorded for leaf extract (400 mg/kg body weight) of <em>L. monopetala</em>. So, the study corroborates the significant antidiarrheal activity of <em>M. cordata</em> and <em>L. monopetala</em> leaf extracts and raises the demand of further sophisticated investigation.</p><p> </p>
