Non-alcoholic fatty liver induces many complications to the liver tissue and also serum related parameters. Medicinal plants are the safe therapeutic strategy for the treatment of diseases. In this regards, the present study was conducted to evaluate the effect of Tribulus terrestris L. (Zygophyllales: Zygophyllaceae) extract on non-alcoholic fatty liver in rats. In this experimental study, thirty male Wistar rats were divided into five groups (n = 6). Animals in experimental groups were received high fructose diet (70%) (HDF) daily alone or in combined with daily intraperitoneal injection of 500, 700 and 1,000 mg/kg extract of T. terrestris. Control group of rats was feed with standard chow. The serum levels of biomarkers of liver and serum lipid profiles were assessed, also histopathological examination of liver tissue done. Data were analyzed using One-way ANOVA method followed by Tukey’s post-hoc multiple comparison test and P < 0.05 was considered statistically significant. There were significant improvements for biomarkers of liver tissue (P < 0.05) and serum lipid profiles (P < 0.01) in the HFD-fed rats that were treated with T. terrestris extract compare to HFD-fed group. In addition, accumulation of lipids in hepatocytes was significantly reduced in the HFD-fed + extract administrated groups in comparison to HFD-fed rats (P < 0.01). T. terrestris extract has protective effects against non-alcoholic fatty liver by changing biomarkers of liver tissue, serum lipid profiles and histopathological anomalies of liver tissue, to normal range.

Gymnema sylvestre of the family Asclepiadaceae is one of the most important medicinal plants of the central eco-region. It is popularly known as Gurmar, which means “sugar killer”. Extract of leaves is reported to have tannins, gum, flavonoids, proteins and saponins. It has displayed a wide array of pharmacological activities. This study was aimed to investigate the antidiabetic and hypolipidemic effects of Gymnema sylvestre extract in experimentally induced diabetes in rats. Diabetes was produced in adult Wistar rats with single dose of streptozotocin (STZ) @ 60 mg/kg b.wt. intraperitoneally. After the confirmation of diabetes on 7th day (sugar >200 mg/dl), alcoholic and aqueous extracts of G. sylvestre (400 mg/kg) were administered orally to the experimental rats from 8th day and continued for 42 days thereafter. The antidiabetic and hypolipidemic activity was estimated by measuring blood glucose, lipid profile and histopathological examination of various tissues from all the groups. Administration of STZ resulted in a significant (p less than 0.01) increase in blood glucose and lipid profile and histopathological alterations in Diabetic control group as compared to healthy control group. Gymnema treatment demonstrated significant (p less than 0.01) antidiabetic effect indicated by restoration of blood glucose compared to STZ control group. The study concluded that extracts of Gymnema sylvestre improved the altered glucose and lipid profile in diabetic rats, suggesting that the Gymnema Sylvestre extracts exhibit the antidiabetic and hypolipidemic activity.

AbstractFailure in the treatment of P. aeruginosa, due to its broad spectrum of resistance, has been associated with increased patient mortality. One alternative approach for infection control is quorum quenching which was found to decrease virulence of such pathogen. In this study, the efficiency of a recombinant Ahl-1 lactonase formulated as a hydrogel was investigated to control the infection of multidrug resistant (MDR) P. aeruginosa infected burn using a murine model. The recombinant N-acylhomoserine lactonase (Ahl-1) was formulated as a hydrogel. To test its ability to control the infection of MDR P. aeruginosa, a thermal injury model was used. Survival rate, and systemic spread of the infection were evaluated. Histopathological examination of the animal dorsal skin was also done for monitoring the healing and cellular changes at the site of infection. Survival rate in the treated group was 100% relative to 40% in the control group. A decrease of up to 3 logs of bacterial count in the blood samples of the treated animals relative to the control group and a decrease of up to 4 logs and 2.3 logs of bacteria in lung and liver samples, respectively were observed. Histopathological examination revealed more enhanced healing process in the treated group. Accordingly, by promoting healing of infected MDR P. aeruginosa burn and by reducing systemic spread of the infection as well as decreasing mortality rate, Ahl-1 hydrogel application is a promising strategy that can be used to combat and control P. aeruginosa burn infections.

Abstract Background Perioperative bleeding is the most common complication related to transurethral resection of prostate; the aim of the study was to compare the effect of pre-operative use of finasteride versus cyproterone acetate (CPA) on blood loss with monopolar TURP. Methods This prospective randomized controlled study was conducted on (60) patients with BPH underwent monopolar TURP between July 2019 and July 2020. Patients were distributed into three equal groups; CPA group: 20 patients received cyproterone acetate 50 mg tab BID for two weeks before TURP, finasteride group: 20 patients received single daily dose of finasteride 5 mg for two weeks before TURP, control group: 20 patients received no treatment before TURP, all patients underwent monopolar TURP, and then histopathological examination of the resected tissues was done with assessment of the microvascular density of the prostate. Results Our study showed that there was significant decrease in intraoperative blood loss and operative time in CPA and finasteride groups in comparison with control group (p = 0.0012) (p < 0.0001), respectively, significant decrease in post-operative Hb and HCT value in finasteride and control groups in comparison with CPA group (p < 0.01), significant increase in specimen weight in CPA group compared to other groups (p < 0.01), and there was also significant decrease in microvascular density in CPA group in comparison with other groups (p < 0.01). Conclusion Cyproterone acetate is more effective than finasteride in decreasing perioperative bleeding with TURP by decreasing microvascular density of the prostate.

To investigate the protective effects of galangin on liver toxicity induced by carbon tetrachloride (CCl4) in mice. Mouse hepatotoxicity model was established by intraperitoneal injection (i.p.) of 10 ml/kg body weight CCl4 that diluted with corn oil to a proportion of 1:500 on Kunming mice. The mice were randomly divided into five groups named control group, model group, and 1, 5, and 10 mg/kg galangin group. The levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were analyzed by ELISA. Liver histopathological examination was observed via optical microscopy. The levels of superoxide dismutase (SOD), malondialdehyde (MDA), glutathione (GSH), and glutathion (GSSG) were analyzed to assess oxidative stress. Finally, western blot assay was carried out to analyse the expression levels of total AMP-activated protein kinase (AMPK), phospho-AMPK (p-AMPK), total liver kinase B1 (LKB1), and phospho-LKB1 (p-LKB1). Compared with the control group, in the model group, the levels of AST, ALT, MDA, and GSSG increased significantly ( p < 0.01); the activity of SOD and GSH decreased significantly ( p < 0.01); and the histopathological examination revealed liver necrosis. However, treatment with galangin (5 and 10 mg/kg) significantly reversed these CCl4-induced liver damage indicators. Furthermore, treatment with galangin (10 mg/kg) significantly increased the p-AMPK and p-LKB1 expression levels ( p < 0.01). This study supports the hepatoprotective effect of galangin against hepatotoxicity, perhaps occurring mainly through the LKB1/AMPK-mediated pathway.

AbstractPotentilla anserina L. is not only a medicinal plant, but also a traditional cuisine. Hence, an acute toxicity study was performed to confirm its safety profile. Forty Kunming mice were randomly divided into two groups: control group and P. anserina L. extract group. Using the maximum dosage method, the P. anserina L. extract group was given the maximum dose within 12 h, equivalent to 345.6 g/kg crude drug. The control group was given distilled water. After administration, toxicity symptoms of mice were observed, body weight and food intake were recorded. After 14 days, blood was collected to measure biochemical parameters, autopsy was carried out to observe the changes of organs, and the vital organs were separated, weighed, and preserved for histopathological examination. The results showed that P. anserina L. extract group had no toxic symptoms. The activity, weight, and diet of mice were normal, and no abnormality was found in organ index, renal function, liver function, anatomical observation, and histopathological examination. Therefore, the maximum oral dosage (345.6 g/kg) of P. anserina L. was good safety. This study indicated that P. anserina L. had a large safety range and the clinical application was safe.

In this study, it was aimed to investigate the protective effect of black seed oil against testicular tissue damage in diabetic rats. A total of 18 male rats were divided into 3 groups, including 6 rats in each group.Groups; control (n=6), diabetes (n=6), diabetes + black seed oil (n=6). A single dose of 45 mg / kg streptozocine (STZ) was injected intraperitoneally to induce diabetes. Diabetes + Black seed oil group: For 56 days, 2.5 ml / kg of black seed oil was administered orally to rats.The rats were sacriced at the end of 56 days. Testicular tissues were taken for routine parafn tissue processing for histopathological examination. Parafn sections were stained with Hematoxylin-Eosin and PAS and examined under a light microscope. Atrophy and degeneration were observed in the seminiferous tubules of diabetic group. Histology of black seed oil group sections were similar to that of control group. A signicant difference was found between the black seed oil group and the diabetes group in terms of blood glucose values. As a result, we think that Black Seed Oil ameliorates to the tissue damage caused by diabetes and the decrease in blood sugar value.

This research was conducted to study the protective effect of bee honey on the 7,12-dimethylbenz(a)anthracene (DMBA)- induced breast cancer in rat model. The study consisted of three groups: honey group, positive control group (PC), and negative control group (NC) to which the carcinogen was not administered. All rats were fed the diet recommended by the American Institute of Nutrition for growing rats (AIN-93G), with addition of honey (50 g/kg diet) to the honey group. All Rats were fed their diets ad libitum on 12 hours dark/light cycle. At the age of 50 days all rats in the honey and PC groups were gavaged once by the carcinogen DMBA with a dose of 80 mg/kg body Wt. After three weeks of carcinogen administration, rats were palpated weekly to detect any tumor growth. After 18 weeks, all rats were sacrificed. The palpable structures and the mammary glands along with associated lymph nodes were removed and fixed in saline formalin and prepared for histopathological examination. The results revealed that the honey group diet significantly (p < 0.05) reduced the incidence rate of mammary cancer, palpable tumor multiplicity, tumor size and weight compared to the PC group. In conclusion, multi floral honey has a protective effect against DMBA- induced mammary cancer in the initiation, promotion, and progression stages of DMBA-induced mammary carcinogenesis. However, further research is needed to reveal the mechanisms that might have contributed to the preventive effect of honey against mammary cancer.

This study was carried out to investigate the effect of experimental infection by Escherichia coli on some blood parameters and histopathological changes in male rats to reach this objective twenty male rats (Rattus norvigicus) were divided into two groups, housed under same conditions of water, feed, temperature, light and humidity. The first one served as control group, while the second was experimentally infected with Ecoli by administration of 2ml / rat of (1×109) colony forming unit/ml of E-coli. Five days later blood were obtained from animals by cardiac puncture to measure the total and differential white blood cells count hemoglobin concentration packed cells volume red blood cells count, and thrombocytes count. One animal from each group was killed and histopathological examination was done for intestine kidney liver and spleen to detect the effect of infection on these organs. The results revealed a significant increase in total leukocytes count (P<005) in infected group while the differential count showed a significant increase in neutrophils and significant decrease in lymphocytes (P< 0.05) in same group. There were a significant decrease in hemoglobin concentration packed cell volume and non significant decrease in red blood cells count. While thrombocytes count showed a significant decrease in infected group compared with control group (P<0.05). The histopathological examination of infected male rats intestine was demonstrated mild diffuse inflammation which include increased numbers of neutrophile in tissue intraepithelial lymphocytes and goblet cells In kidney renal tubules showed extensive epithelial swelling with decreased lumen space and generalized necrotic changes with interstitial hemorrhage in renal cortex. In liver hepatocytes were swollen with decreased sinusoidal spaces and widely distributed necrotic foci were seen. There is extensive splenic necrosis with infiltration of leukocytes from white pulp to red pulp of spleen.
