Up to now, the control of malaria remains a challenge. The World Health Organization (WHO) recommends the use of artemisinin-based combination therapies (ACTs) for uncomplicated malaria treatment. Despite this guideline, many people in Burkina Faso use herbal medicine as primary treatment against malaria. The aim of this study was to assess the in vivo activity of Guiera senegalensis J. F. Gmel and Bauhinia rufescens Lam. leaves extracts against Plasmodium berghei ANKA. A four-day treatment of leaves decoction of each plant was administrated orally to 7 groups of six NMRI (Naval Medical Research Institute) mice infected with Plasmodium berghei ANKA strain. The control group received distilled water as treatment while the treated groups each received daily 100, 250, and 500 mg extract/kg body weight. Thin blood smears were performed on day five and the percentage of reduction of parasitaemia was determined compared to the control. The percentages of reduction of the parasitaemia at the doses of 100, 250, and 500 mg extract/kg body weight were, respectively, 57.5%, 35.9%, and 44.9% for Guiera senegalensis and 50.6%, 22.2%, and 25.7% for Bauhinia rufescens. Our findings on antiplasmodial activity of these two plants justify the traditional use by local populations against malaria. Thus, the isolation of the active compounds from these two plants is suggested for possible antimalarial candidate drugs.

Forty five rats aged 6 weeks were divided into three groups, i.e., control group without probiotic (a0), Lactobacillus casei Shirota (a1), and Lactobacillus IS-7257 (a2).  Each group (consisting of 5 rats each) has three different treatments, namely, control without oxygenated water (b0), 50 ppm oxygenated water (b2), and 80 ppm oxygenated water (b2). Oxygenated water was administered to the rats twice a day in the morning (3.25 ml) and afternoon (3.00 ml). Observation was carried out on the body  weight of the rats, fecal lactic acid bacteria, coliform, and anaerob bacteria by plate counting, for 4 periods, i.e, prior to the treatment (C0), after three-day treatment (C1), after seven-day treatment (C2), and on the 10<sup>th</sup> day treatment or three days after washed out period. The results indicated that probiotic bacteria are resistant to acid and bile acid condition. Oxygen concentration in water has a significant positive influence on the body weight of rats towards viability of probiotic bacteria (p-level &lt; 0.05).  The supplementation of  oxygenated water 50 ppm significantly increase the population of viable fecal lactic acid bacteria in L. casei Shirota and Lactobacillus IS-7257 groups after 3 and 7 days of treatment.  Lactobacillus IS-7257 gave better response than L. casei Shirota. The supplementation of oxygenated water 80 ppm significantly reduces the fecal coliform in-vivo in both L. casei Shirota and Lactobacillus IS-7257 groups (p-level &lt; 0.05).</span></p>

SUMMARYEmergence of malaria parasites resistant to artemisinin necessitates the need for development of new antimalarial therapies. Ciprofloxacin (CFX) a second generation quinolone antibiotic possesses some antimalarial activities. We investigated the in vivo antimalarial activities of CFX in combination with amodiaquine in mice infected with chloroquine-resistant Plasmodium berghei ANKA. Animals were treated orally with 80 or 160 mg kg−1 body weight of CFX alone given twice daily or in combination with amodiaquine (AQ) 10 mg kg−1 body weight. Parasitological activity and survival of the animals were assessed over 21 days. Peak parasitaemia in the untreated control group was 72·51%. Treatment with AQ alone resulted in clearance of parasitaemia by day 4 while treatment with CFX 80 and 160 mg kg−1 alone suppressed parasitaemia by 13·94–54·64% and 35·6–92·7%, respectively. However, the combination of CFX with AQ significantly enhanced response of infection in the animals to treatment (P < 0·05) resulting in complete resolution of parasitaemia throughout follow up period with CFX 160 mg kg−1, delayed recrudescence time with CFX 80 mg kg−1 and significant increase in survival rate of the animals. The results demonstrate beneficial interaction between AQ and CFX which may provide a clinically relevant antimalarial/antibiotic therapeutic option in the management of malaria.

Abstract Background: Pergularia tomentosa L. is a milkweed tropical plant. In the Middle Est, the aerial parts of P. tomentosa are traditionally used as an anti-diabetic remedy. In order to find scientific evidence for the traditional use of this plant, the effect of an aqueous extract of P. tomentosa aerial parts by in vivo assay was investigated. Moreover, to achieve deeper insight into the chemical composition of the above-mentioned extract an analytical approach based on LC-ESI/LTQOrbitrap/MS/MSn was evaluated. Wistar rats were fasted overnights and diabetes mellitus induced using streptozotocin (50 mg/kg body weight). The rats were randomly and equally divided into four groups (n=5): group I (normoglycaemic control), group II (rats treated with streptozotocin 50 mg/kg body weight), group III (P. tomentosa extract 200 mg/kg body weight), group IV (normoglycaemic treated with P. tomentosa extract, 200 mg/kg body weight). At the end of the treatment period, they were anesthetized under diethylether. Vital organs (kidneys, liver and pancreas) and blood samples were obtained for histopathological, biochemical and haematological analysis.Results: P. tomentosa showed a reasonable reduction in blood glucose level. Probably, P. tomentosa effect on hyperglycemic and hyperlipidemic diabetic animals was associated to antioxidant properties, triglyceride levels, as well as the liver enzymes. Furthermore, the metabolite profile of the aqueous extract of P. tomentosa obtained by LC-ESI/LTQOrbitrap/MS/MSn highlighted the presence of double-linked cardenolides along with cardenolides and flavone glycosides. Conclusion: P. tomentosa decreased the glucose level and induced beneficial effect on lipid profile. This study confirms the capability of cardenolide glycosides to decrease the level of glucose in the blood.

Malaria afflicts millions of people globally, particularly in tropical Africa; it is transmitted to humans through a bite of an Anopheles mosquito. Phytochemical, acute toxicity and in-vivo antiplasmodial activity of the leaves of Ageratum conyzoides were examined to study its effects on Mice that have been infected with the malaria parasite. Phytochemical screening of the methanol extract revealed the presence of secondary metabolites such as terpenoids, flavonoids, alkaloids, steroids and chromene. The LD50 was established at ˃ 1000 mg/kg body weight of mice. The methanol extract of A. conyzoides displayed intrinsic prophylactic and curative anti-malaria activity. At 200 mg/kg and 100 mg/kg body weight of mice, the extract revealed the highest percentage inhibition (83 and 61) for the prophylactic and curative study respectively. The acute toxicity study showed that A. conyzoides extract is relatively safe within the study administered doses. The methanol extract of the prophylactic study against Plasmodium berghei revealed an increase in the level of significance at administered portions of 100, 200 and 400 mg/kg in comparison with 0.2 ml distilled water and 10 mg/kg chloroquine. The methanol extract of the therapeutic study against Plasmodium berghei revealed a slight increase in the level of significance at administered doses of 100 and 200 mg/kg, however, no significant effect was observed for 400 mg/kg compared to the negative control and reference drug. The outcome implies that methanol leave extract of A. conyzoides possesses meaningful antiplasmodial activities and could be a promising source of novel antimalarial.Keywords: Malaria, Ageratum conyzoides, phytochemical screening, acute toxicity, Plasmodium berghei

Overtraining syndrome is a decrease in physical capacity, emotions and immunity due to training that is too often without adequate periods of rest. Overtraining is often experienced by athletes who daily undergo heavy training with short break periods. This research aims to look at the effect of overtraining aerobic physical exercise on memory in mice. The research method was experimental in vivo with the subject of adult male rat (Rattus Norvegicus) Winstar strain aged 8-10 weeks, body weight 200-250 gr. Divided into three groups, namely the control group, aerobic group and overtraining group. The results of memory tests with water E Maze showed an increase in the duration of travel time and the number of animal errors made by the overtraining group (p = 0.003). This study concludes that overtraining aerobic physical exercise can reduce memory in rat hippocampus.

Adipogenic Gene

Excess body weight is a major risk factor for type 2 diabetes (T2D) and associated metabolic complications, and weight loss has been shown to improve glycemic control and decrease morbidity and mortality in T2D patients. Weight-loss strategies using dietary interventions produce a significant decrease in diabetes-related metabolic disturbance. We have previously reported that the supplementation of low molecular chitosan oligosaccharide (GO2KA1) significantly inhibited blood glucose levels in both animals and humans. However, the effect of GO2KA1 on obesity still remains unclear. The aim of the study was to evaluate the anti-obesity effect of GO2KA1 on lipid accumulation and adipogenic gene expression using 3T3-L1 adipocytes in vitro and plasma lipid profiles using a Sprague-Dawley (SD) rat model. Murine 3T3-L1 preadipocytes were stimulated to differentiate under the adipogenic stimulation in the presence and absence of varying concentrations of GO2KA1. Adipocyte differentiation was confirmed by Oil Red O staining of lipids and the expression of adipogenic gene expression. Compared to control group, the cells treated with GO2KA1 significantly decreased in intracellular lipid accumulation with concomitant decreases in the expression of key transcription factors, peroxisome proliferator-activated receptor gamma (PPARγ) and CCAAT/enhancer-binding protein alpha (CEBP/α). Consistently, the mRNA expression of downstream adipogenic target genes such as fatty acid binding protein 4 (FABP4), fatty acid synthase (FAS), were significantly lower in the GO2KA1-treated group than in the control group. In vivo, male SD rats were fed a high fat diet (HFD) for 6 weeks to induced obesity, followed by oral administration of GO2KA1 at 0.1 g/kg/body weight or vehicle control in HFD. We assessed body weight, food intake, plasma lipids, levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) for liver function, and serum level of adiponectin, a marker for obesity-mediated metabolic syndrome. Compared to control group GO2KA1 significantly suppressed body weight gain (185.8 ± 8.8 g vs. 211.6 ± 20.1 g, p < 0.05) with no significant difference in food intake. The serum total cholesterol, triglyceride, and low-density lipoprotein (LDL) levels were significantly lower in the GO2KA1-treated group than in the control group, whereas the high-density lipoprotein (HDL) level was higher in the GO2KA1 group. The GO2KA1-treated group also showed a significant reduction in ALT and AST levels compared to the control. Moreover, serum adiponectin levels were significantly 1.5-folder higher than the control group. These in vivo and in vitro findings suggest that dietary supplementation of GO2KA1 may prevent diet-induced weight gain and the anti-obesity effect is mediated in part by inhibiting adipogenesis and increasing adiponectin level.

<p class="Abstract">In this study the antidiarrheal activity of ethanolic extracts of the leaves of <em>Mikania cordata</em> and <em>Litsea monopetala</em> was evaluated. Diarrhea was induced in mice by oral administration of castor oil (0.5 mL) 30 min after the administration of the extracts. During a 4 hour study the number of diarrheal feces and percentage inhibition of the extracts (200 and 400 mg/kg body weight) was determined. Loperamide (3 mg/kg body weight) served as standard and belonged to the positive control group. The extracts exhibited potent antidiarrheal activity as well as achieved statistically significant p value (p&lt;0.01 and p&lt;0.05) compared to control group. Among the extracts the highest percentage inhibition of defecation (60%) was recorded for leaf extract (400 mg/kg body weight) of <em>L. monopetala</em>. So, the study corroborates the significant antidiarrheal activity of <em>M. cordata</em> and <em>L. monopetala</em> leaf extracts and raises the demand of further sophisticated investigation.</p><p> </p>

Abstract Sequestration of Plasmodium berghei ANKA-infected erythrocytes occurs in BALB/c mice as characteristic of  Plasmodium falciparum infection in humans. Animals’ bile has been widely used for centuries in Traditional Chinese Medicine. Goat bile has been used in healing infectious and non-infectious diseases; however, no report on the use of goat bile against malaria infection and sequestration. The purpose of this study was to analyze the correlation between parasitemia and sequestration in the liver of P.berghei ANKA-infected BALB/c mice treated with goat bile. This research was an in vivo experimental study using the post-test control group design. The male BALB/c mice aged ± 6 weeks, body weight 20-25 g were used. The mice were divided into five groups where Group 1-3 were mice treated with goat bile 25%, 50%, and 100%, respectively. Group 4-5 were negative (sterile water) and positive controls (DHP). Parasitemia was observed daily from each mouse and the number of sequestered infected erythrocytes on the endothelium of sinusoids. The data were analyzed using t independent test. Antimalarial activity of goat bile was shown by the lower parasitemia in goat bile-treated mice compared with the negative control. The average number of sequestration was goat bile concentration-dependent manner. The higher the concentration, the lower the number of sequestration. Sequestration was correlated with parasitemia (p=0,0001). Sequestration of P.berghei ANKA-infected erythrocytes correlated with parasitemia, and was goat bile concentration-dependent manner. Keywords: Malaria, parasitemia, sequestration, goat bileCorrespondence: [email protected]

Background: The extract of Corchorus olitorius has a reasonable content of vitamins A and C, calcium, iron and fibre, and therefore enjoys a universal application in the treatment of some disease conditions, even as the whole leaf is a very important component of food in so many cultures. Purpose: The study was designed to investigate the effect of Corchorus olitorius extracts on the testis of adult Wistar rats. Method: A total number of thirty two adult Wistar rats weighing between 180 and 200 grammes separated into four groups labeled A,B,C and D respectively were used for the study. Animals in group A which served as the control group were fed with the normal rat chow and water only. The group B rats were administered 100mg/kg body weight of aqueous extract of Corchorus olitorus; while those in group C were administered 500mg/kg body weight of the extract. The group D rats received 1000mg/kg body weight of the extract. For a period of four weeks, the different experimental animal groups received the respective aforementioned treatments once daily, around nine- o’clock in the morning through oral intubation. At the end of the 28 day treatment, the animals were sacrificed and the testes harvested for histological, investigation, and through cardiac puncture, blood samples for some hormonal studies was also collected and investigated using standard laboratory standards. Results: Observations made showed that the extract produced no histological distortions, degenerative or defective effects on the testicular tissues. The testosterone levels of group B, C, and D rats were observed to be significantly higher (P<0.005) than that of the group A (control group).ound: The extract of Corchorus olitorius has a reasonable content of vitamins A and C, calcium, iron and fibre, and therefore enjoys a universal application in the treatment of some disease conditions, even as the whole leaf is a very important component of food in so many cultures.
