Aloe vera have active chemicals substances including saponins, tannins, flavonides, and polyphenols. Saponin takes a role as a disinfectant, so it is normally effective for healing any open wounds, while tannins have ability to be an antiseptic. This study aims to see how the effect of the Aloe vera gel on wound collagen, and too inspect which is the most effective concentration of the Aloe vera gel in the formation of wound collagen in wistar strains (Rattus novergicus) rats. This study uses a post-test only method with control group design. The subjects of this study were 28 male Wistar rats (Rattus novergicus). The subjects were divided into 4 groups consisting of 1 negative control group and 3 treated groups, the control group was not given any treatment, while the treated group was given the Aloe vera gel with each concentrations of 12.5%, 25%, and 50% respectively. The experiment was started by making a wound on the back of the rat which then be followed by applying the gel to the wound for 14 days. The results showed the group with the 50% Aloe vera gel treatment had the best collagen formation, followed by a concentration of 25%, 12.5%, and the control group. Therefore, the used of Aloe vera has given good change in scar collagen, and the best scar collagen can be viewed in the group with 50% concentrate of Aloe vera.

Insulin resistance, which precedes type 2 diabetes mellitus (T2DM), is a widespread pathology associated with the metabolic syndrome, myocardial ischemia, and hypertension. Finding an adequate treatment for this pathology is an important goal in medicine. The purpose of the present research was to investigate the effect of an extract from Aloe vera gel containing a high concentration of polyphenols on experimentally induced insulin resistance in mice. A polyphenol-rich Aloe vera extract (350 mg/kg) with known concentrations of aloin (181.7 mg/g) and aloe-emodin (3.6 mg/g) was administered orally for a period of 4 weeks to insulin resistant ICR mice. Pioglitazone (50 mg/kg) and bi-distilled water were used as positive and negative controls respectively. Body weight, food intake, and plasma concentrations of insulin and glucose were measured and insulin tolerance tests were performed. The insulin resistance value was calculated using the homeostasis model assessment for insulin resistance (HOMA-IR) formula. Results showed that the polyphenol-rich extract from Aloe vera was able to decrease significantly both body weight ( p < 0.008) and blood glucose levels ( p < 0.005) and to protect animals against unfavorable results on HOMA-IR, which was observed in the negative control group. The highest glucose levels during the insulin tolerance curve test were in the negative control group when compared to the Aloe vera extract and pioglitazone treated mice ( p < 0.05). In conclusion, Aloe vera gel could be effective for the control of insulin resistance.

Introduction: Some studies indicated that antlions (Myrmeleon sp.) is traditionally used by many people in Indonesia as a diabetes treatmenter. However. reseach has not been done to find the effect of antlion extract in pancreas, an important organ in diabetes mellitus pathophysiology. Objective: To prove the effect of antlion extract towards histopathological feature of pancreas in diabetic mice.Methods: In the post test only control group design, 25 Swiss mice were divided into five groups. Normal group (Nor-G), Negative control group (Neg-G), and the other 3 groups were intraperitoneally injected with Streptozotocine 200 mg/kg to induce diabetic state. In Neg-G had no antlion treatment, whereas in At-14, At-28, and At-56 were treated with antlion extract at the dose of 14, 28, and 56 mg/kg BW respectively for 24 days. Pancreas then collected and prepared to be examined under microscope with 400x magnification. The score of pancreatic islet injury was determined by assessing structural damage and inflammatory cells infiltration. Kruskal-Wallis and Mann-Whitney were adopted as statistical analysis.Results: Mann-Whitney analysis indicated that the score of pancreatic islets injury in At-56 was significant lower compared to that of Neg-G, p<0.05. The score of pancreatic islets injury in At-56 also significant lower compared to that of At-14 and At-28, p<0.05. In contrary, when compared to that of Nor-G, the pancreatic islets injury in At-56 was not signicantly lower, p>0.05.Conclusion: Antlion extract treatment at the dose of 56 mg/kg BW was capable of reducing pancreatic islet injury in diabetic mice induced by streptozotocine.

Abstract Objective: To test the hypothesis that the administration of aspirin, acetaminophen, meloxicam, celecoxib, and prednisolone have no effect on root resorption and tooth movement. Materials and Methods: A mesial force of 50 g was applied to the left maxillary first molars of sixty 10-week-old male Wistar rats using nickel titanium closed coil springs attached to the cervical area of the incisors. The rats were randomly divided into 12 groups of 5 each. High and low doses of aspirin, acetaminophen, meloxicam, celecoxib, and prednisolone were administered via drinking water for 2 weeks. The experimental control group had tooth movement but received no drug. The negative control group received neither tooth movement nor drugs. The amount of tooth movement was measured on digitized lateral cephalometric radiographs. Rats were sacrificed after 2 weeks. Mesial and distal roots (distobuccal and distopalatal) were examined using scanning electron and three-dimensional (3D) scanning laser microscopes. The surface area, depth, volume, and roughness of the root resorption craters were measured. Results: When compared with experimental control rats, only prednisolone- and high-dose celecoxib-treated groups showed significantly less root resorption and less tooth movement. Although low dose celecoxib-treated group significantly decreased the tooth movement, root resorption was similar to the control group. Furthermore, resorption craters showed a smoother surface in the prednisolone-treated rats. Conclusions: The hypothesis was rejected. Administration of prednisolone and high-dose celecoxib reduces root resorption and interferes with tooth movement in rats. Both drugs may interfere in the arachidonic acid cascade depending on dose thresholds.
