Abstract Background The menace of resistance to anti-malarial drugs is a great challenge to malaria control, necessitating the search for new anti-malarial agents. This search has led to the exploration of natural products for efficacy in malaria therapy. Omidun is the supernatant of fermenting maize (ogi) slurry that has been widely investigated and reported to possess several health benefits and it is used traditionally as solvent for preparing anti-malarial herbs. However, there is no information on the anti-malarial activity of omidun itself. This study was conducted to investigate the prophylactic, curative and suppressive anti-malarial potential of omidun. Methods Experimental mice in the curative group were infected with 1 × 106 cells of Plasmodium berghei strain ANKA and treated with either 0.2 ml of omidun containing 3 × 109 cfu/ml of viable lactic acid bacteria or 0.2 ml of 5 mg/kg of chloroquine (positive control) or 0.2 ml of saline (negative control) for 4 days from day 3 post infection. The prophylactic group of mice were pre-treated with either omidun, chloroquine or saline for 4 days before infection with P. berghei, while the suppressive group was treated with omidun or chloroquine or saline and infected with P. berghei simultaneously. A group of mice were uninfected but treated (with omidun and control samples), while a final group was uninfected and untreated (controls). Parasitaemia and histopathology analysis were done in all groups. Results The curative and suppressive groups showed a significant difference between the omidun-treated mice (100% parasitaemia reduction) and the untreated mice (54.5% parasitaemia increase). There was no significance difference between the omidun treatment and chloroquine (positive control) treatment in suppressive group as both treatment had 100% parasitaemia reduction. The omidun prophylactic treatment however did not show any parasitaemia suppression, but a significant difference was observed between the omidun treatment (85% increase) and the chloroquine (positive control) treatment (100% reduction) in the group. Omidun treatment is non-toxic to the kidney. Conclusion This study provides scientific evidence supporting omidun usage in the treatment of malaria. Consequently, further work may yield the specific component of omidun responsible for the anti-malarial activity.

Kersen leaf (Muntingia calabura L.) contains tannins, flavonoids and polyphenol compounds allegedly have analgesic effect. The objective was to determine the analgesic effect of ethanol extract of kersen leaves and to determine the most effective analgesic dose. This study was an experimental research. Leaves were extracted with ethanol 70% and the analgesic effect test was divided into 5 groups: negative control treatment (distilled water), positive control (mefenamic acid 2.6mg/kg), kersen leaf ethanol extract first dose (100mg/kg), second dose (200mg/kg) and tthird dose (400mg/kg). Giving treatments by oral, after 30 minutes, the mices were given a pain inductor with 0.5% acetic acid by intra peritonial administration. Analgesic power was calculated by counting the number of writhing in mice for 1 hour. The results showed that the ethanol extract of cherry leaf has analgesic effect. From the calculation of the first dose analgesic power (42.9%), second dose (59.4%) and the third dose 69.9%. Statistical test results kruskal wallis value of p=0.011 (p<0.05) showed a significant difference between all analgesic treatment groups. The conclusion of this study is all of the ethanol extract had analgesic effects on male white mice, whereas a dose of 400mg/kg is the most effective analgesic dose.

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.

AbstractThere is a need for new targets to specifically localize inflammatory foci, usable in a wide range of organs. Here, we hypothesized that the cleaved molecular form of CD31 is a suitable target for molecular imaging of inflammation. We evaluated a bioconjugate of D-P8RI, a synthetic peptide that binds all cells with cleaved CD31, in an experimental rat model of sterile acute inflammation. Male Wistar rats were injected with turpentine oil into the gastrocnemius muscle two days before 99mTc-HYNIC-D-P8RI (or its analogue with L-Proline) SPECT/CT or [18F]FDG PET/MRI. Biodistribution, stability study, histology, imaging and autoradiography of 99mTc-HYNIC-D-P8RI were further performed. Biodistribution studies revealed rapid elimination of 99mTc-HYNIC-D-P8RI through renal excretion with almost no uptake from most organs and excellent in vitro and in vivo stability were observed. SPECT/CT imaging showed a significant higher 99mTc-HYNIC-D-P8RI uptake compared with its analogue with L-Proline (negative control) and no significant difference compared with [18F]FDG (positive control). Moreover, autoradiography and histology revealed a co-localization between 99mTc-HYNIC-D-P8RI uptake and inflammatory cell infiltration. 99mTc-HYNIC-D-P8RI constitutes a new tool for the detection and localization of inflammatory sites. Our work suggests that targeting cleaved CD31 is an attractive strategy for the specific in vivo imaging of inflammatory processes.

This study determined the effect of Mango mistletoe Methanolic Extract (MMME) on the cardiac's histopathological profile of hypertensive rats (DOCA-Salt) treated. The MMME was treated on fifty rats for 14 days, divided into five treatments: negative control, positive control, doses 50, 100, and 200 mg/kg BW with five replications. One-way ANOVA analysis was used, namely JAMOVI with version 1.1.9.0, and for cell calculation, diameter using the IMAGE J application. Results showed that there were no significant differences in the histopathological profile of the cardiac in hypertensive rats (DOCA-Salt) treated with MMME for 14 days on the diameter of the heart muscle cells between the control (+) and control groups (-), treatments 1, 2, and 3. This is evidenced by the analysis of p-value> 0.05, namely 0.187 millimeters. Therefore, we concluded that MMME does not affect the diameter of heart/cardiac organ muscle cells. However, there was a significant difference in the amount of necrosis in the cardiac of hypertensive rats between control (+) and control (-) groups, treatments 1, 2, and 3. Based on the results, MMME reduces the number of necrosis in the heart/cardiac organ.
