Abstract Background: This study was carried out to determine the blood pressure changes in experimentally Trypanosoma brucei brucei-infected Wistar albino rats and diminazene aceturate-treated rats. Methods: Twenty-four rats were purchased and divided into four groups consisting of six rats each. Control group (CON) received 0.5 mL of distilled water, i.m., infected but not treated group (INF) received 2×106 trypanosome/mL i.m., infected but diminazene aceturate-treated group (INFDIM) received 2×106 trypanosome/mL, 3.5 mg/kg, i.m.) and non-infected but diminazene aceturate-treated group (DIM) received 3.5 mg/kg, i.m. and served as negative control. The blood pressures were measured using a CODA 2® non-invasive blood pressure monitor (Kent Scientific, USA). The results were compiled and statistical analysis was done with significance set at p≥0.05. Results: The values of the blood pressure readings of the Trypanosoma-infected INF (137.0±2.0 mmHg) and diminazene-treated rats INFDIM (125.0±7.5 mmHg) when compared to the control group (168.0±3.0 mmHg) were significantly lower (p≤0.05) at the end of day 7. The heart rate was also significantly reduced in the INF (403.5±1.5 beats/min) and DIM (445.0±24 beats/min) groups of rats when compared with the control group (613.0±2.0 beats/min) at the end of day 8. Conclusion: The findings indicate the significant reduction in blood pressure and heart rates during Trypanosoma brucei brucei infection and with diminazene aceturate administration. Hence, caution should be exercised when treating trypanosome-infected patients with diminazene aceturate.

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.

Background: Infection can lead to delayed wound healing. Recently it has been shown that propolis which is used in complementary medicine has an antibacterial and anti-inflammatory effect. The aim of this study is to determine whether propolis may contribute to wound healing. Material and Methods: Twenty-one male Wistar albino rats were randomly divided into three groups. Group1 and Group 2 were topically treated with propolis ointment and Thiocillin® oinment, respectively while Group 3 was the control group. On incision wound model, Thiocillin® and propolis ointments were applied on wound sites once daily for 30 days and the mean epidermal thickness (MET) at the 30th day was compared while antimicrobial activity of propolis was studied against different pathogens as well. Results: Propolis exhibited in vitro antibacterial activity against Staphylococcus aureus, Escherichia coli, Streptococcus sp. and Pseudomonas sp. It is observed that the MET in the groups of Propolis ointment and Thiocillin® ointment were significantly greater than that of the control group, while the MET in the group of propolis ointment was significantly greater than that of Thiocillin® ointment treated group. Conclusion: Propolis is effective in wound healing. Further study in-depth is necessary to probe into clinical correlation.

El objetivo de este estudio fue comparar la predicción del V̇O2máx. entre mujeres sobrevivientes de cáncer de mama y un grupo control (GC) de mujeres sin antecedentes de cáncer. Estudio de caso-control en que diecisiete mujeres en el grupo sobrevivientes de cáncer de mama (49.4 ± 8.9 años, índice de masa corporal [IMC] de 27.8 ± 2.7 kg·m-2) y 17 en el GC (47.9 ± 7.4 años, IMC de 26.2 ± 4.4 kg·m-2) fueron evaluadas. La prueba de caminata de seis minutos (PC6M) se evaluó con monitor de frecuencia cardíaca, tensiómetro digital, oxímetro de pulso y escala de Borg. El V̇O2máx. se estimó con ecuación que consideró la distancia recorrida, el peso corporal y la edad. El grupo de sobrevivientes caminó 34.8 metros más que el GC (p = .15; d = .51). También mostró una tendencia (p = .05), con un tamaño del efecto moderado (d = .76), hacia un aumento del V̇O2máx. (1.74 ± .26 L·min-1) comparado con el GC (1.56 ± .21 L·min-1). No hubo diferencias entre los grupos para las variables de frecuencia cardíaca, presión arterial y esfuerzo percibido durante la prueba (p > .05). Las participantes que recorrieron más distancia tuvieron más probabilidades de un mayor V̇O2máx. (odds ratio = 12.7; p = .002). Existieron diferencias en el V̇O2máx. entre los dos grupos, esta aptitud física debería considerarse para el tratamiento y control post-operatorio. Abstract. The aim of the study was to compare the prediction of the V̇O2max in breast cancer survivors and a control group (CG) of women without a history of cancer. It is a case-control study. Seventeen women in the breast cancer survivors (49.4 ± 8.9 years, body mass index [BMI] of 27.8 ± 2.7 kg·m-2) and 17 in the CG (47.9 ± 7.4 years, BMI of 26.2 ± 4.4 kg·m-2) were evaluated. The six-minute walk test (SMWT) was evaluated with a heart rate monitor, digital blood pressure monitor, pulse oximeter and the Borg scale. The V̇O2max it was estimated with an equation that considered the distance traveled, body weight and age. The survivors group walked 34.8 meters more than the CG (p = .15). In addition, group showed a trend (p = .05), with a moderate effect size (d = .76), towards an increase in V̇O2max (1.74 ± .26 L·min-1) compared to the CG (1.56 ± .21 L·min-1). There were no differences between the groups for the variables of heart rate, blood pressure and perceived exertion during the test (p > .05). The participants who covered the longest distance had a better chance of a V̇O2max higher (odds ratio = 12.7; p = .002). There were differences in the V̇O2max between groups, this physical fitness should be considered for post-operated treatment and monitoring.

Purpose: To compare the anti-trypanosomal efficacies of 4,4-(diazoaminedibenzamidinetrihydrate) diacetate (4,4-DDBT) and 4,4-(diazoamino) benzamidine (4,4-DB) in experimental canine trypanosomosis. Methods: The efficacies of 4,4-DDBT and 4,4-DB were evaluated in 4 groups of dogs (n = 3) designated A-D. Group A was normal control without infection or drug treatment, group B did not receive any drug treatment but was infected with Trypanosoma brucei brucei, while groups C and D were infected with T. b. brucei and treated with 4,4-DDBT(3.5 mg/kg) and 4,4-DB (3.5 mg/kg), respectively. Results: The incubation period of the infection was 6 - 9 days post-infection. Treatment of the dogs with 4,4-DDBT led to zero parasitaemia 48 h post-treatment, while there was only a decrease in parasitemia to log 6 in 4,4-DB-treated dogs. Resurgence of parasite into the blood stream occurred in 4,4-DDBTtreated dogs 6 days after initial parasite clearance. Blood analyses post-treatment revealed elevated leucocytes and lymphocytes in 4,4-DB-treated dogs (p < 0.05). Packed cell volume was also observed to be higher in 4,4-DDBT-treated group when compared to 4,4-DB group (p < 0.05). Conclusion: These findings suggest that 4,4-DDBT is more efficacious in the clinical management of canine trypanosomosis caused by T. b. brucei. However, it does not prevent relapse of infection. Based on these findings, therefore, 4,4-DDBT should be the diminazene salt of choice when indicated in the clinical management of T. b. brucei infection in dogs.

Background: Liver damage can be occurred due to prolonged use of higher doses of some drugs, exposure to some chemicals or infectious agents. But liver protective drugs are not available in modern medicine. Some hepatoprotective herbal medicines are often used in the treatment of liver damage. Objective: This experimental study was carried out to observe the hepatoprotective effect of Oyster mushroom (Pleurotus florida) against paracetamol induced liver damage in Wistar albino rats. Method: This experimental study was carried out in the Department of Physiology, Sir Salimullah Medical College (SSMC), Dhaka from 1st July 2009 to 30th June 2010. A total number of 34 Wistar albino rats, age ranged from 90 to 120 days, weighing between 150 to 210 grams were selected for the study. After acclimatization for 14 days, they were divided into two groups, control group (Group A) and experimental group (Group B- mushroom pretreated and paracetamol treated group). Control group again subdivided into group A1 (baseline control) and group A2 (paracetamol treated control group). All groups of animals received basal diet for 30 consecutive days. Group A1 consisted of 10 rats, received propylene glycol (2 ml/kg bw, orally) only on 30th day. Group A2 consisted of 14 rats, received single dose of paracetamol suspension (750 mg/ kg bw, orally) only on 30th day. Group B consisted of 10 rats, received mushroom extract (200 mg/ kg bw, orally) for 30 consecutive days and paracetamol suspension (750 mg/ kg bw, orally) only on 30th day. All the animals were sacrificed on 31st day. Then blood and liver samples were collected. Initial body weight, final body weight and liver weight were measured. Then measurement of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in serum and assessment of malondialdehyde (MDA) concentration in liver tissue homogenate were done by using standard laboratory kits. The statistical analysis was done by one way ANOVA and Bonferroni test as applicable. Result: The mean serum AST, ALT levels and in the liver tissue MDA concentration were significantly (p<0.001) higher in paracetamol treated group in comparison to those of baseline control group. Again, the mean serum AST (p<0.05), ALT (p<0.05) levels and in the liver tissue homogenate MDA concentration (p<0.001) were significantly lower in mushroom pretreated and paracetamol treated group (experimental group) when compared to those of only paracetamol treated group (control). Conclusion: This study reveals that Oyster mushroom (Pleurotus florida) which is excellently edible and nutritious, may have some hepatoprotective role.
