Anti-trypanosomal effect of Malva sylvestris (Malvaceae) extract on a Trypanosoma brucei brucei-infected mouse model of sleeping sickness

Purpose: To evaluate the antitrypanosomal activity of Malva sylvestris (MS) extract in a Trypanosoma brucei brucei-infected mouse model of sleeping sickness.Methods: Sleeping sickness was induced by the intraperitoneal injection of Trypanosoma brucei brucei infected blood in mice. Confirmation of parasitaemia was performed by estimating the parasite count in the plasma on the 12th day after inoculation. All the mice were divided into five groups: control group that received neither infection nor treatment; negative control that was infected with the parasite but did not receive treatment; MS-treated group that receive MS extract (250 and 500 mg/kg, ip) and standard (STD) group that received levamisole (7.5 mg/kg, ip) for 7 days after the development of parasitaemia. A further parasite count was performed in the blood and cerebrospinal fluid (CSF) after the treatment period. Humoral antibody response, delayed hypersensitivity reaction, and mobilization of leucocytes were determined after the treatment period in SRBC-sensitized mice.Results: The results indicate that treatment with MS significantly decreased body weight and parasite count in the blood and CSF of mice with Trypanosoma brucei brucei-induced sleeping sickness compared with that in the negative control group. There was a significant increase in paw swelling and decrease in secondary antibody in the MS-treated group compared with that in the negative control group. However, treatment with MS extract also enhanced the mobilization of the total leucocyte count compared with that in the negative control group.Conclusion: The results demonstrate the anti-trypanosomal activity of Malva sylvestris extract via immunomodulation in a Trypanosoma brucei brucei-infected mouse model of sleeping sickness.Keywords: Malva sylvestris, Trypanosoma brucei brucei, Sleeping sickness, Immunomodulatory activity, Delayed hypersensitivity reaction

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.

Abstract Airway remodelling refers to the structural changes that occur in the airway wall in asthma. These is irreversible changes to the airway, with damage of bronchiolus epithelium because the airway epithelium undergoes apoptosis as one of its manifestations. Empirically black seed has been known as bronchial asthma therapy for many years ago. The purpose of the research is to test the effect of black seed (Nigella sativa L.) extract to apoptosis of bronchiolus epithelium and apoptosis of T lymphocytes the airway bronchial asthma on asthma mouse model. Female mice were used in the expeimental laboratory research and allergic mouse model was got by given ovalbumin twice within 3 weeks intraperitoneally and 3 times per week within 6 weeks by inhalation. Black seed extract is given in 3 different dose (0,024 cc/day, 0,048 cc/day and 0,096 cc/day) for 9 weeks. Sample was chosen randomly to share it within 5 group containing 6 mice in every group ; negative control group (without any treatment, n=6), positive control group (sensitizied with ovalbumin, n=6), JH1 group (sensitizied with ovalbumin and treating with first dose of black seed extract, n=6), JH2 group (sensitizied with ovalbumin and treating with second dose of black seed extract, n=6), JH3 group (sensitizied with ovalbumin and treating with third dose of black seed extract, n=6). The parametric that is used in this research is the change in the color of the nucleus of bronchiolus epithelium and T lymphocytes the airway bronchial asthma shown the occurrence of browning apoptosis. The result shown a significant increase of apoptosis of bronchiolus epithelium on positive control group to compare with negative control group. The apoptosis of bronchiolus epithelium on JH1 shown an increase compare with positive control group. For JH2 and JH3 groups shown a decrease the apoptosis of bronchial epithelium compare with positive control group. And the research indicate that the unsignificant aptosis decrease were happen on a group with positive control instead of the group with negative control. Meanwhile, on JH1 group, apoptosis decrease were happening more significantly than the positive control group does, the aptosis increases were happen on JH2 and JH3 group, but its not capable to exceeding the positive control group apoptosis amount The conclusions is the black seed (Nigella sativa L.) extract can decrease apoptosis of bronchiolus epthelium on asthma mouse model in the third dose as the best result and the doses of black seed extract that were giving to the experiment mice can not increasing the apoptosis T Lymphocyte, thus requiring further research to figure out the perfect doses to increasing against respiratory tract apoptosis T Lymphocyte.

The aim of this study was to compare the vertical fracture resistance of roots obturated with different root canal filling materials and sealers. Crowns of 55 extracted mandibular premolar teeth were removed to provide root lengths of 13 mm. Five roots were saved as negative control group (canals unprepared and unfilled). Fifty root canals were instrumented and then five roots were saved as positive control group (canals prepared but unfilled). The remaining 45 roots were randomly divided into three experimental groups (n=15root/group) and obturated with the following procedures: in group 1, glass ionomer-based sealer and cone (ActiV GP obturation system); in group 2, bioceramic sealer and cone (EndoSequence BC obturation system); and in group 3, roots were filled with bioceramic sealer and cone (Smartpaste bio obturation system). All specimens were tested in a universal testing machine for measuring fracture resistance. For each root, the force at the time of fracture was recorded in Newtons. The statistical analysis was performed by using Kruskal-Wallis and post hoc test. There were no significant differences between the three experimental groups. The fracture values of three experimental and negative control groups were significantly higher than the positive control group. Within the limitations of this study, all materials increased the fracture resistance of instrumented roots.

Cirrhotic Patients

Introduction: For over 30 years, ascites has been postulated to facilitate fibrinolysis in patients with liver cirrhosis. In contrast to previous research employing conventional coagulation tests, this study aimed to characterize hemostatic interactions between blood and ascites using the rotational thromboelastometry (ROTEM). Methods: Blood samples – pure or mixed with ascites in a ratio of 1:1 – from cirrhotic patients (n = 10) were subjected to ROTEM analysis. In addition, a negative control group was built with cirrhotic patients (n = 10) whose blood was mixed with physiologic sodium chloride (0.9% NaCl) solution in a ratio of 1:1. Subsequently, ROTEM measurements were subjected to statistical analysis. Results: During ascites challenge, clotting time (CT, measured in seconds) was significantly prolonged in EXTEM (blood: 70.40 ± 20.40 vs. ascites/blood: 109.8 ± 47.7) and APTEM (blood: 66.50 ± 14.55 vs. ascites/blood: 138.7 ± 105.8), likely reflecting a dilution effect. However, CT in INTEM remained unchanged, suggesting a sustained intrinsic pathway function. Maximal clot firmness (measured in millimeters) in FIBTEM decreased significantly (blood: 14.70 ± 9.55 vs. ascites/blood: 6.00 ± 5.66), thus indicating depletion of fibrinogen in ascites. Strikingly, maximum lysis (measured in %) significantly decreased in EXTEM (blood: 9.30 ± 2.79 vs. ascites/blood: 5.50 ± 2.84), APTEM (blood: 8.50 ± 3.10 vs. ascites/blood: 5.60 ± 2.88), and INTEM (blood: 7.50 ± 2.27 vs. ascites/blood: 5.10 ± 3.48). Conclusions: ROTEM provided new evidence that ascites may not primarily induce fibrinolysis in cirrhotic patients. This finding seems to be of significant importance for the clinical management of cirrhotic patients experiencing complications, for example, abdominal hemorrhage after liver biopsy or paracentesis; here, replacement of prothrombin complex concentrates and/or fibrinogen concentrates may prove more beneficial than the use of fresh frozen plasma or antifibrinolytic drugs.

Abstract Background The objective of the present study was to explore the benefits of Porcine circovirus 2 (PCV-2) blanket vaccination in a sow herd on productive parameters, PCV-2 infection and immune status in sows and their progeny. For this purpose, 288 sows were distributed among four balanced experimental groups. One group remained as negative control group and the other three received 1 mL of PCV-2 Ingelvac Circoflex® intramuscularly at different productive cycle moments: before mating, mid gestation (42–49 days post-insemination) or late gestation (86–93 days post-insemination); phosphate buffered saline (PBS) was used as negative control item. Reproductive parameters from sows during gestation and body weight of their progeny from birth to weaning were recorded. Additionally, blood was collected from sows at each vaccination time and piglets at 3 weeks of age. Moreover, up to 4 placental umbilical cords (PUC) per sow were taken at peri-partum. Sera from sows and piglets were analysed for PCV-2 antibody detection using an enzyme-linked immunosorbent assay (ELISA). Sera from sows and PUC were tested to quantify viraemia using a real time quantitative polymerase chain reaction (qPCR) assay. Results Globally, results indicated that vaccinated sows showed heavier piglets at birth and at weaning, less cross-fostered piglets, lower viral load at farrowing as well as in PUC, and higher antibody levels at farrowing, compared to non-vaccinated ones. When all groups were compared among them, sows vaccinated at mid or late gestation had heavier piglets at birth than non-vaccinated sows, and lower proportion of PCV-2 positive PUC. Also, cross-fostering was less frequently practiced in sows vaccinated at pre-mating or mid gestation compared to non-vaccinated ones. Conclusions In conclusion, the present study points out that PCV-2 sow vaccination at different time points of their physiological status (mimicking blanket vaccination) offers benefits at production and serological and virological levels.
