Background: Anti-plasmodial activities of the methanol stem bark extracts of Nauclea latifolia, and Terminalia glaucescens were investigated in mice infected with Plasmodium berghei. Methods: A total of 24 Plasmodium berghei infected (P. berghei infected) mice were divided into 8 groups of 3 each. Groups A-F were given 100, 300 or 500 mg/kg of either extracts. Groups G and H received 2 mL normal saline (negative control) and 5 mg/kg of chloroquine (positive control), respectively. The drugs and extracts were administered orally once daily for five days. Results: Alkaloids and flavonoids were the most and abundant metabolites in the extracts, respectively. The extract of Nauclea latifolia (N. latifolia) and Terminalia glaucescens (T. glauscecens) had Median Lethal Dose LD50 of >5000 mg/kg and 3808 mg/kg, respectively. In vivo anti-plasmodial studies revealed that the highest suppression (66.79% and 65.37%) and mean survival days (27.67±1.45 and 30.33±0.33) were recorded for the groups treated with 500 mg/kg N. latifolia or T. glaucescens, respectively. The infected but untreated groups survived only for 9.33±0.88 days while chloroquine treated groups lived for 31.33±0.88 days. The body weight and Packed Cell Volume (PCV) of rats treated with 500 mg/kg. N. latifolia or T. glaucescens significantly increased (P<0.05) compared to those in the infected but untreated groups. There was a significant loss (P<0.05) in body weight and PCV of the mice treated with 100 mg/kg of T. glaucescens compared to those in other treated groups. Conclusion: The extracts exhibited anti-plasmodial activities in mice, therefore, they may be considered potential candidates for new anti-malarial agents.

Many species of medicinal plants have been used as a therapeutic alternative in the treatment of diseases around the world, as well as promoting advances in the production of herbal medicines. However, this use is often done indiscriminately and leads to serious consequences in the body of those who use them. Therefore, studies on the toxic, cytotoxic, and genotoxic potentials of medicinal plant species are necessary for their safe use. Cenostigma gardnerianum Tul, popularly known as Caneleiro or Canela-de-velho, is widely used by the population for its anti-inflammatory, antispassmolytic, antitussive, antifungal properties, among others. The aim of this research was to study and analyze a possible toxicity, cytotoxicity, and genotoxicity of the ethanolic extract from the bark of the stem of Cenostigma gardnerianum Tul. by means of the Allium cepa in vivo bioassay. The extract was divided into four concentrations, divided into groups A, B, C and D, respectively: 0.5mg/ml, 1.0mg/ml, 2.0mg/ml and 5.0mg/ml, in addition to the Negative Control (dechlorinated water), Positive Control (dimethyl sulfoxide) and Blank control (distilled water). The roots were measured for toxicity evaluation, the Mitotic Index (MI) was calculated for cytotoxicity research, and finally micronuclei count was performed to study the genotoxicity of each extract concentration. The low growth of the meristems indicated the presence of toxicity; the mitotic indices found were statistically lower than in the negative control, revealing cytotoxicity; and the high micronucleus count showed the presence of genotoxicity. From the results obtained, it was concluded that the ethanolic extract of the Caneleiro bark presents toxic, cytotoxic, and genotoxic activity, with statistically significant values for concentrations starting from 2mg/ml.

Nitrofurantoin (NT) used for the treatment of urinary tract infections may have antiplasmodial activity. Dihydroartemisinin-piperaquine (DP) is an artemisinin based combination therapy used for the treatment of malaria. This study evaluated the antiplasmodial effect of dihydroartemisinin-piperaquine-nitrofurantoin (DP-NT) on mice infected with Plasmodium berghei. Adult Swiss albino mice (30-35 g) of both sexes were used. The mice were randomly grouped, inoculated with Plasmodium berghei, and treated orally with DP (1.7/13.7 mg/kg), NT (57.1 mg/kg) and DP-NT (1.71/13.7/ 57.1 mg/kg), respectively using curative, prophylactic and suppressive tests. The negative control was orally treated with normal saline (0.3 mL), while the positive control was orally treated with chloroquine CQ (10mg/kg). After treatment, blood samples were collected and evaluated for percentage parasitemia, inhibitions and hematological parameters. Liver samples were evaluated for histological changes. The mice were observed for mean survival time (MST). Treatment with DP-NT decreased parasitemia levels when compared to individual doses of DP and NT with significant difference observed at p<0.05. DP-NT prolonged MST when compared to individual doses of DP and NT with significant difference observed at p<0.05. The decrease in packed cell volume, red blood cells, hemoglobin and increase in white blood cells in parasitized mice were significantly restored by DP-NT  when compared to individual doses of DP and NT with difference observed at p<0.05. DP-NT eradicated liver Plasmodium parasite.  NT remarkably increased the antiplasmodial activity of DP. DP-NT may be used for the treatment of malaria.

Ficus vogelii is a medicinal plant mainly found in tropical Africa and reported to treat inflammatory complaints. This study aims to evaluate the acute and sub-chronic toxicity of the aqueous extract of Ficus vogelii stem bark in wistar rats. For acute study, aqueous extract at a single dose of 5000 mg/kg body weight was administered to female rats and observed for 14 days. In the sub-chronic study, the extract was administered daily to both sex rats at the doses of 100, 200, 400, and 600 mg/kg body weight for 28 consecutive days. Body weight was measured weekly, while hematological, biochemical, and histopathological parameters were analyzed after euthanize. Aqueous extract of Ficus vogelii at all tested doses didn’t produced any mortality or significant change on the body weight and relative weight of rats on acute and sub-chronic studies. The lethal dose 50 was estimated greater than 5000 mg/kg (DL50˃5000 mg/kg). Hematological parameters were recorded non-significant in all treated rats. Aqueous extract at 600 mg/kg significantly changed transaminases and alkaline phosphatase activities, these changes were reversible in satellites. The concentrations of bilirubin was increased at 200 and 600 mg/kg in male rats, at 100, 400 mg/kg in female rats. The levels of lipids markers didn’t changed, except the significant decrease of LDL-cholesterol. Histological examination didn’t showed any change in the architecture of the liver and kidney of rats treated compared to control. Thus aqueous extract of Ficus vogelii stem bark didn’t produced adverse effects in rats after oral acute and sub-chronic treatment.

Two trials were conducted on floor pens to evaluate the performance of broilers fed with diets contained different carbohydrases enzyme programs at different ages. Trial 1- The body weight gain (BWG) was affected by the Negative Control (NC) treatment (P<0.05). However, when the birds were fed with the NC diet + Amilase (AMY)+Xilanase (XYL), the BWG improved and reached the same level as the Positive Control (PC). Trial 2- The birds received enzymes supplementation in the total phase and others only in the grower phase.The ME reduction by 120 kcal/kg increased the feed conversion ratio (FCR) (P<0.05) when compared to PC and none of the enzyme programs was able to recover the performance. It can be concluded that it is possible to supplement with AMY during the role period of broiler chicken life or use an enzymatic program with AMY or AMY+XYL only in the grower phase.

Borrelia burgdorferi, the agent of Lyme disease, and B. turicatae, a neurotropic agent of relapsing fever, are susceptible to vancomycin in vitro, with an MIC of 0.5 microgram/ml. To determine the activity of vancomycin in vivo, particularly in the brain, we infected adult immunocompetent BALB/c and immunodeficient CB-17 scid mice with B. burgdorferi or B. turicatae. The mice were then treated with vancomycin, ceftriaxone as a positive control, or normal saline as a negative control. The effectiveness of treatment was assessed by cultures of blood and brain and other tissues. Ceftriaxone at a dose of 25 mg/kg of body weight administered every 12 h for 7 to 10 days eliminated cultivable B. burgdorferi or B. turicatae from all BALB/c or scid mice in the study. Vancomycin at 30 mg/kg administered every 12 h was effective in eliminating infection from immunodeficient mice if treatment was started within 3 days of the onset of infection. If treatment with vancomycin was delayed for 7 days or more, vancomycin failed to eradicate infection with B. burgdorferi or B. turicatae from immunodeficient mice. The failure of vancomycin in eradicating established infections in immunodeficient mice was associated with the persistence of viable spirochetes in the brain during antibiotic treatment.

The experiment was conducted to investigate the protective effect of Petroselinum crispum leave extracted against gentamicin-induced nephrotoxicity in male rabbits by studying the body weight, clinical signs, haematological and biochemical parameters, gross lesion and histopathological changes. Twenty four rabbits male were used and divided into 4 groups. Group 1: rabbits served as a negative control, received distilled water 1 ml(orally). Group 2: rabbits served as a positive control group, received gentamicin at a dose of 80 mg/kg/day intramuscular for 15 days. Group 3: rabbits received gentamicin at a dose of 80 mg/kg/day then after one hour treated with ethanolic extract of Petroselinum crispum at dose 125 mg/kg orally for 15 days. Group 4: rabbits received gentamicin at a dose of 80 mg/kg/day then after one hour treated with ethanolic extract of Petroselinum crispum at dose 250 mg/kg orally for 15 days.The results of the gentamicin treated group( positive control group) showed clinical signs such as loss of body weight, loss of appetite and rough hair with hematuria. The body weight a significantly declined (p≤ 0.05) compared other groups. There was a significant decrease (p≤ 0.05) in WBC count, lymphocyte, GSH, SOD, CAT, and GPX levels, while it recorded a significant increase (p≤0.05) in weights of the kidneys, neutrophils, creatinine, urea, and MDA. Histological studies showed several kidney pathological changes such as pale colour, enlargement in size and weight and easy from detaching as opposed to negative control group. On the other hand, the group treated with ethanolic extractof Petroselinum crispum at dose 125 mg/kg induced improved of parameters as recorded significant increased(P ≤ 0.05) in body weight, WBC count, lymphocyte, GSH, SOD, CAT, and GPX, while significant decreased (P ≤ 0.05) in weights of the kidneys, neutrophils, creatinine, urea, and MDA compared with the positive control group whereas rabbits treated with ethanolic extract of Petroselinum crispum at dose 250 mg/kg restored the parameters and histological changes of the kidney to near normal status compared with the negative control group. These results showed that the dose-detected Petroselinum crispum extract (250mg / kg) acts as potential curative effect against gentamicin-induced nephrotoxicity in male rabbits.

The current study examined the attenuating influence of dietary carrot pomace powder (CaPP) on hypercholesterolemia and various oxidative stress-associated with biochemical parameters in hypercholesterolemic rats. Thirty two male albino rats weighing 110±10 g were divided into four groups, the first group received the basal diet only and served as (negative control), the second group received the hypercholesterolemic diet and served as positive control, the other groups received hypercholesterolemic diet supplemented with 10%, 20% CaPP for six weeks. The obtained results revealed that groups supplemented with 10% and 20% CaPP significantly decrease total lipid, total cholesterol, triglycerides, low density lipoprotein cholesterol, liver enzymes: alanine aminotransferase, aspartate aminotransferase compared to positive and negative groups. Organs weight, body weight gain significantly decreased compared with positive control. Moreover dietary carrot pomace powder can used to reduce the body weight and reducing hypercholesterolemic complications. In addition, dietary carrot pomace powder serves to improve the blood picture and to reduce the blood glucose level in hypercholesterolemic rats and could use in obese people for body loss. Data of kidney function (Urea) record an increase in CaPP 20% level (26.9±2.96) but this increase was non significant with the negative control group (26.6±3.1).
