Methanolic Extracts

The aqueous and methanolic extracts of Rumex bequaertii leaves were investigated for their ability to prevent and treated ulceration of the gastric mucosa in animal models.For this, adult male rats three to four months old and weighing on average 180 g were used for both tests. The extracts were tested orally at doses of 125, 250 and 500 mg/kg, on ulcerations experimentally induced by HCl/ethanol and pylorus ligation (acute ulcer) and acetic acid (chronic ulcer).These extracts showed protective and healing properties on ulcer induced models. A dose of 500 mg/kg of the two extracts inhibited ulceration induced by HCl/ethanol by 98.86 and 91.59 % respectively. With pyloric ligation, no significant variation of the volume of gastric juices, pH and gastric acidity was observed compared to the negative control rats. The aqueous extract alone at different doses presented a significant reduction of the ulceration surface resulting from chronic ulcer induced with acetic acid compared to the negative control group that received distilled water. For all three models of gastric ulcer induction used, the mass of mucus significantly increased in the groups that received the extracts. There was no significant variation in plasmatic nitric oxide (NO) concentrationand gastric supernatant of rats treated with both extracts compared to both control groups. These results reveal that the healing process of the extracts is not achieved through the NO pathway. This process could be due to increase in mucus production and thus supports its traditional use of the plant

This study investigated the efficacy of different chemotherapeutic regimes in the treatment of rats experimentally infected with diminazene aceturate-resistant strain Trypanosoma brucei brucei. Thirty Sprague Dawley male rats used for the study were randomly assigned to six groups of five rats eachas follows: group A-uninfected untreated (negative control), group B-infected and untreated (positive control), groups C-F were infected and treated with 1.0 mg/kg isometamidum chloride, administered intramuscularly on day 11 post-infection. However, rats in groups D, E and F received further treatments with 700 mg/kg sodium-ethylenediamine tetra-acetic acid, 0.4 mg/kg verapamil and 3 mg/kg chlorpromazine, respectively, administered orally for four days. Clearance of parasite post-treatment (PT), mortality PT, relapse parasitaemia post-clearance, body weight change, rectal temperature, packed cell volume (PCV), haemoglobin (HB) concentration and red blood cell count (RBC) were determined during the experiment. Result showed parasite clearance PT of 100% in groups D and E, 80% in group F and 20% in group C by 24 hours PT. The infection relapsed on day 35 PT in 40% of rats in group C, on day 37 PT in 20% of rats in group F and lastly 20% of rats in groups D and E on day 39 PT. Rats that received drug combination showed marginal improvement in erythrocytic parameters analysed when compared with those treatment with isometamidium alone. Combination therapy showed faster clearance of parasite from the blood and also prolonged relapse post-clearance, thus had a better promising efficacy when compared to using isometamiduim chloride alone.

Biomaterials for use in guided bone regeneration (GBR) are constantly being investigated and developed to improve clinical outcomes. The present study aimed to comparatively evaluate the biological performance of different membranes during the bone healing process of 8 mm critical defects in rat calvaria in order to assess their influence on the quality of the newly formed bone. Seventy-two adult male rats were divided into three experimental groups (n = 24) based on the membranes used: the CG—membrane-free control group (only blood clot, negative control), BG—porcine collagen membrane group (Bio-Guide®, positive control), and the PCL—polycaprolactone (enriched with 5% hydroxyapatite) membrane group (experimental group). Histological and histometric analyses were performed at 7, 15, 30, and 60 days postoperatively. The quantitative data were analyzed by two-way ANOVA and Tukey’s test (p < 0.05). At 7 and 15 days, the inflammatory responses in the BG and PCL groups were significantly different (p < 0.05). The PCL group, at 15 days, showed a large area of newly formed bone. At 30 and 60 days postoperatively, the PCL and BG groups exhibited similar bone healing, including some specimens showing complete closure of the critical defect (p = 0.799). Thus, the PCL membrane was biocompatible, and has the potential to help with GBR procedures.

Abstract Introduction Burn is one of the most severe traumas that causes coagulative destruction of the skin. The use of various products that accelerate wound healing in patients with burn may affect the patient’s survival and reduce the complications that may be seen. In the present study we aimed effects of subcutaneous ozone injection on second degree burn wound. Methods A total of 72 Sprague-Dawley male rats included in the study were divided randomly into three groups (control group (CG), silver sulfadiazine group (SG), ozone group (OG)) and each group was divided randomly two subgroups (as sacrificed on d7 and on d14).A deep second degree scald burns were created on the lower back. In CG subcutaneous 0.9% serum saline was injected daily into the burn area. In SG, burns were dressed with silver sulfadiazine daily and in OG subcutaneous ozone was injected daily into the burn area. Tissue hydroxyproline level measurement and histopathological evaluation were done. Results When the groups were compared in terms of weight change, no significant difference was found on the 7th and 14th days. In the evaluation made in terms of tissue hydroxyproline, tissue hydroxyproline level in OG was found to be significantly higher on both the 7th and 14th days (p &lt; 0.001). In histopathological evaluations, it was determined that wound healing in OG was significantly higher than in the other groups. Conclusions According to the results, subcutaneous ozone therapy is more effective than silver sulphadiazine in the healing process of second-degree burn wounds and it can be safely used in the treatment of burn wounds.

Objectives. To estimate the impact of ellagic acid (EA) towards healing tooth socket in diabetic animals, after tooth extraction.Methods. Twenty-fourSprague Dawleymale rats weighing 250–300 g were selected for this study. All animals were intraperitoneally injected with 45 mg/kg (b.w.) of freshly prepared streptozotocin (STZ), to induce diabetic mellitus. Then, the animals were anesthetized, and the upper left central incisor was extracted and the whole extracted sockets were filled with Rosuvastatin (RSV). The rats were separated into three groups, comprising 8 rats each. The first group was considered as normal control group and orally treated with normal saline. The second group was regarded as diabetic control group and orally treated with normal saline, whereas the third group comprised diabetic rats, administrated with EA (50 mg/kg) orally. The maxilla tissue stained by eosin and hematoxylin (H&E) was used for histological examinations and immunohistochemical technique. Fibroblast growth factor (FGF-2) and alkaline phosphatase (ALP) were used to evaluate the healing process in the extracted tooth socket by immunohistochemistry test.Results. The reactions of immunohistochemistry for FGF-2 and ALP presented stronger expression, predominantly in EA treated diabetic rat, than the untreated diabetic rat.Conclusion. These findings suggest that the administration of EA combined with RSV may have accelerated the healing process of the tooth socket of diabetic rats, after tooth extraction.
