Aims: The effect of pre and post-infection administration of zinc and selenium on Trypanosoma brucei brucei infection in wistar rats on some biochemical parameters were investigated. Study Design:  The study was designed to evaluate the effect of pre and post infection administration of zinc and selenium on Trypanosoma brucei brucei infection in wistar rats. Place and Duration of Study: The study was conducted at the Nigerian Institute for Trypanosomiasis Research (NITR), Kaduna and Department of Biochemistry, Ahmadu Bello University (ABU), Zaria, between January 2014 to March 2014. Methodology: Fifty four (54) wistar rats were divided into nine groups of six (6) rats each. Groups III-IX were infected intraperitoneally with 1x103parasite load. Animals in group III were                       infected but untreated while the infected/treated groups received prophylactic (IV, V and VI) and therapeutic (VII, VIII and IX) treatment with zinc and selenium 50mg/kg and 10mg/kg body weight respectively. Results: Results obtained showed that serum alkaline phosphatase (ALP), alanine amino transferase (ALT) and aspartate amino transferase (AST) activities in the infected-untreated control group were significantly different (P<0.05) and higher as compared to infected treated and normal control. Similarly, the two minerals significantly decreased (P<0.05) the levels of Urea and Creatinine in the infected treated when compared to the infected untreated rats, with the exception of creatinine value of the post-infected treated with selenium where there was no significant (P>0.05) decrease. On the other hand, a significant (P<0.05) increase in serum levels of total Protein, albumin and total bilirubin and no significant (P>0.05) difference in direct bilirubin was recorded in infected treated group compared to infected untreated and normal control. Conclusion: It was concluded that administration of zinc and selenium ameliorate the infection-induced biochemical changes in tissues and organs associated with Trypanosoma brucei brucei infection in Wistar rats.

Trigona honey (TH) is well known for its therapeutic characteristics. To date, the study of Trigona honey as a prophylactic or immune booster prior to the bacterial infection of the invivo model is not well covered. This study aims to investigate anti-inflammatory and immune activities in Wistar rats infected with respiratory infection following with Trigona honey. 25 Wistar rats were assigned to possitive groups, negative control group, positive control group was fed TH (5 g / kg body weight) orally, the untreated group was infected with Staphylococcus aureus to induce respiratory infection, the treated group has been infected with S. aureus followed by treatment with TH at a dose of 1.5 ×108 CFU / mL and the preventive group ingested TH one week before S. aureus infection. Blood was obtained for biochemical analysis. Lung tissues have been collected for molecular examination. The results showed a significant decrease in serum levels of ALT, AST, urea and creatinine in the preventive and treated groups, serum IgG increased significantly (P<0.05) in the preventive and treated groups, IFN-y increased in the preventive group while decreased in the treated group, and IL-8 increased in the treated group while decreased in the preventive group. The mRNA expression of AGP is up-regulated in the positive control, preventive and treated groups. The α2-MG, TNF-α , and mRNA expressions showed lower regulation after administration of TH in preventive and treated groups. The results show the ability of TH to counteract immune and inflammatory changes in serum levels and gene expressions.

Animal African trypanosomiasis (AAT) also known as Nagana is a resurgent disease in Africa. Medicinal plants are being used in less developed countries for the treatment of various diseases including trypanosomiasis, due to the high cost of currently available drugs. Most of these plants have been useful sources of treatment of various diseases based on information obtained from folk medicine but have not been scientifically certified. Here, we investigated the in vitro and in vivo anti-trypanosomal potentials of the methanol extract of Aformorsia laxiflora and Khaya senegalensis against T. b. brucei. Phytochemical screening as well as LD50 of the plant extracts was carried out following standard procedures. Parasitemia was monitored daily while Packed Cell Volume was determined at three time points (days 1, 4 and 7) during the course of the infection. The phytochemical analysis showed the presence of saponins, alkaloids, flavonoids, antraquinones, resins and tanins. However, steriods/terpenoids were absent in K. senegalensis but present in A. laxiflora. The toxicity of methanol extract of both A. laxiflora and K. senegalensis was above 5000mg/kg body weight. Methanol extracts of A. laxiflora (leaves) and K. senegalensis (stem bark) showed promising trypanocidal potential in vitro against T. b. brucei at concentrations of 10, 15, 25mg/ml and 40 and 20mg/ml respectively. At these concentrations, both extracts immobilized the parasites within 55mins post-incubation. In general, A. laxiflora leaf extract demonstrated prophylactic activity against T. b. brucei in vivo at a dose of 500mg/Kg body weight particularly in group C animals where a delayed pre-patent period (6 days post-infection), extended survival (14 days post-infection) and significant (P<0.05) reduction in the parasite burden confirmed by an absence of anemia (PCV 47.00±0.8 %) was observed when compared to the infected untreated control group. K. senegalensis extract on the other hand did not show anti-trypanosomal activity in the treated groups (1, 2, and 3). Based on these observations, it was therefore deduced that the methanol extract of leaves of A. laxiflora possessed the ability to ameliorate the burden of the disease and could be a plausible candidate for drug development against the disease.Keywords: Trypanosoma brucei brucei, Afromosia laxiflora, Khaya senegalensis, anti-trypanosomal, in vitro, in vivo

Doxorubicin-induced cardiotoxicity is the leading cause of morbidity and mortality among cancer survivors. The present study was aimed to investigate the cardioprotective potential of methyl gallate; an active polyphenolic nutraceutical, against doxorubicin-induced cardiotoxicity in Wistar rats. Twenty-four female Wistar rats (150–200 g) were divided into four groups (n = 6) which consist of normal control (group I), doxorubicin control (group II), test-A (group III), and test-B (group IV). Group III and group IV animals were prophylactically treated with methyl gallate 150 mg/kg/day and 300 mg/kg/day orally, respectively, for seven days. Doxorubicin (25 mg/kg; single dose) was administered through an intraperitoneal route to group II, III, and IV animals on the seventh day to induce acute cardiotoxicity. On the 8th day, besides ECG analysis, serum CK, CK-MB, LDH, AST, MDA, and GSH were assayed. Following gross examination of isolated hearts, histopathological evaluation was performed by light microscopy. A significant ( p  < 0.05) cardiac injury, as well as oxidative stress, was observed in doxorubicin control rats in comparison to normal control rats. Methyl gallate at both the doses significantly ( p  < 0.05) reduced doxorubicin-induced ECG changes, dyslipidaemia, and elevation of CK, CK-MB, LDH, AST, MDA and increased GSH level. Methyl gallate reversed the doxorubicin-induced histopathological changes in the heart. The present study revealed that methyl gallate exerts cardioprotection against doxorubicin-induced cardiotoxicity in female Wistar rats by suppressing oxidative stress. Our study opens the perspective to clinical studies for consideration of methyl gallate as a potential chemoprotectant nutraceutical in the combination chemotherapy with doxorubicin to limit its cardiotoxicity.

This study determined haematological changes in Wistar rats experimentally infected with local strains of Trypanosoma congolense and Trypanosoma brucei brucei. Forty-five Wistar rats between 10 – 12 weeks old weighing between 210 – 240 g were used. The Wistar rats were randomly divided into four groups (A, B, C and D), with the infected groups (B, C and D) having 10 rats each, while the uninfected control group (A) had 15 rats. Group A rats were not infected and served as the control, group B were infected with Trypanosoma congolense, group C were infected with Trypanosoma brucei brucei and group D were co-infected with Trypanosoma congolense and Trypanosoma brucei brucei. Infection was achieved using 0.1mL of blood containing approximately 1 × 103 trypanosomes intraperitoneally into each Wistar rat in the infected groups. Clinical signs were observed. The changes in the blood cells were assayed in the groups post-infection. Duncan’s Least Square Deviation showed significantly (p<0.05) higher parasitaemia in infected groups. However, group D showed a higher significant (p<0.05) difference in parasitaemia when compared to groups B and C. The pattern of mean parasitaemia for the infected groups, revealed a positive correlation with days of post-infection (p<0.05) before the decline. The packed cell volume, total red blood cell count and haemoglobin concentration were significantly (p<0.05) lower in infected groups B, C and D. The total white blood cell count, platelet counts and differential leucocyte count were significantly (p<0.05) lower in infected groups when compared to the uninfected group. These findings suggest that co-infection with Trypanosoma congolense and Trypanosoma brucei brucei obtained from Wurno and Ngaski in Sokoto and Kebbi States respectively produced a more damaging effect on haematological parameters.

The aim of our experimental work was to study whether carvedilol is able to protect renal tissue from cyclosporine toxic effect in animal model of cyclosporine nephropathy. The study was performed on twenty Wistar rats divided in two experimental groups: control (treated with placebo) and carvedilol (treated with p.o. dose 10mg/kg/day in 1 ml solution). Cyclosporine in oral dose of 15 mg/kg/day was administered to all animals during 15 days of experiment. Urine was collected daily for the assessment of diuresis, proteinuria, and determination of urea and creatinine levels. Serum collected at the end of the experiment (day 15) was used for the determination of urea and transferrin levels. The level of renal tissue damage was evaluated by the Jones method for basal membranes, glomeruli and tubuli impregnation, and by the Kossa method for calcium impregnation. For the determination of paranuclear inclusions presence we used chromanilinblue (CAB) method. Statistically significant differences between total protein levels in urine on day 7 of the experiment and urea levels in serum at the end of the experiment in the control group and the carvedilol-treated group indicate a protective effect of carvedilol on renal tissue, which is supported also by the results of a histological examination of renal tissue. Significant increase in the serum transferrin level was registered in the carvedilol-treated group and no significant changes were noted in ceruloplasmin serum levels. In conclusion, our pilot study showed that carvedilol has the ability to protect renal tissue from cyclosporine induced nephropathy in rats.

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.

The study was carried out to investigate the anti-diabetic effects of two medicinal plants Cataranthus roseus (C.R) and Nauclea latifolium (N.L) on some biochemical indices of streptozotocin induced diabetic albino wistar rats. Methods: Ethanolic leaf extracts of C.R. and N.L. were given at daily doses of 500 mg/kg body weight in two divided doses each for 14 days. Thirty albino wistar rats were divided into five (5) groups, consisting of 6 rats each viz: Group 1(normal control), Group 2 (diabetic control), Group 3 (insulin treated), Group 4 (received N.L) and Group 5 (received C.R.). Results: The results of the phytochemical screening contain flavonoids, polyphenols, and alkaloids were found to be present in appreciable amount in N.L while saponins and tannins were found in traceable concentration. Fasting blood glucose levels showed significant decrease (P<0.05) in all the test groups compared to diabetic control and closely related to the insulin treated groups. A significant increase (P<0.05) was observed in (TG) and (TC) concentration of all treated groups compared to the diabetic control group. The concentration of HDL was significantly increased while there was also a significant decreased (P<0.05) in VLDL and LDL in the diabetic control group and insulin group when compared to the normal control group, except for C.R treated group that shows a significant decrease compared with the diabetic control group. Enzymes activities were increased in insulin and diabetic groups. A significant reduction (P<0.05) was observed with the treated group of C.R. and N.L compared to the normal control group. Also, observed was a decrease in albumin level in groups treated with the extracts. Marked reduction in total protein level was observed in groups treated with extracts and insulin, compared to the normal control group. Serum concentrations of Na+, K+, Cl- in diabetic control groups showed a significant increase (P<0.05) compared to the normal control group. K+ concentration was observed to be significantly decreased (P<0.05) in all groups treated with extract and insulin compared to the normal control group. Conclusions: The results demonstrated that C. roseus and N. latifolium have anti-diabetic and antihepatotoxic properties and could be potential herbal remedy in treating and managing diabetic conditions.

Chemotherapy of trypanosomosis has been adversely affected by widespread drug resistance and toxicity. Attention has now been shifted towards the search for ethnobothanical means of controlling the disease. The aimof this study was to determine the effect of methanol extract of the fruit pod of Acacia nilotica on experimental Trypanosoma brucei infection inWistar rats. TwentyWistar rats were randomly alloted into four groups of 5 rats each. Rats in groups I to III were experimentally infected with an isolate of T. brucei while group V served as uninfected control. At day 2 post infection (PI), rats in groups I were orally treated with extract of fruit pod of A nilotica at a dose of 500 mg/kg for 5 days while rats in group II were treated with diminazene aceturate at 3.5mg/kg subcutaneously once. Rats in group III served as infected untreated control. Parasitaemia, PCV and survival rates were monitored during the course of the study. Parasitaemia begins 3 days PI and progressively increased in groups I and III but was not observed in group II. There was decrease in PCV of rats in groups I and III compared to that of groups II and IV. The differences observed in parasitaemia and PCV between the groups compared were not statistically significant (P>0.05).Mortalitywas observed in group I from day 8PIwith 2 rats (40%) surviving up to day 10 PI. All rats in group III died within 7 days post infection while mortalities were not recorded in groups II and IV. It was concluded that the methanol extract of the fruit pod of A. nilotica had no In vivo trypanocidal effect at the dose of 500mg/kg, but demonstrated some ameliorative effect on the severity of the infection in Wistar rats.

Background: Osteoporosis is a metabolic skeletal disease with low bone mass and bone microarchitectural disorganization. Thiazolidinediones (TZD) increase insulin sensitivity through activation of peroxisome proliferator-activated receptor gamma (PPARγ). One of the most important side effects of this drugs is its effects on bone, especially in postmenopausal women. The purpose of this study was to evaluate the effect of diabetes mellitus (DM), insulin, and TZDs on bone in postmenopausal Wistar rats. Methods: Sixteen postmenopausal Wistar rats were divided into four groups: (i) control group, (ii) Streptozotocin-induced DM group without treatment, (iii) Streptozotocin-induced DM group with insulin therapy, and (iv) Streptozotocin-induced DM group receiving rosiglitazone. Pictures of the obtained samples were taken under computer-equipped photo-light microscope, and bone tissue ratios were calculated in an area of 1 mm2. In this area, trabecular thicknesses were measured from six randomly selected regions. In addition, femoral neck regions were determined by measuring the farthest distance. Results: Compared to the control group, trabecular thicknesses were decreased in the uncontrolled DM and rosiglitazone groups. In the rosiglitazone-treated group, trabecular thickness was decreased compared to the uncontrolled DM group. The histological examination of the bones showed that uncontrolled DM and rosiglitazone treatment negatively affected the osteoblast and osteocyte activity. Insulin-treated group had a similar histologic examination compared to the control group. Conclusion: Our study showed that DM had unfavorable effects on bones, and rosiglitazone further exerts this effect. However, the negative effect of DM may be neutralized with the use of insulin.
