Fortification of Fermented Camel Milk with Salvia officinalis L. or Mentha piperita Leaves Powder and Its Biological Effects on Diabetic Rats.

The incorporation of fermented camel milk with natural additives possesses numerous benefits for the treatment of various pathological and metabolic conditions. The present study investigated the impact of fortification of fermented camel milk with sage or mint leaves powder (1 and 1.5%, respectively) on glucose and insulin levels, lipid profile, and liver and kidney functions in alloxan-induced diabetic rats. The gross chemical composition of sage and peppermint leaves powder was studied. The chemical composition of sage and mint extracts was performed using liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-MS) of sage and mint extracts. Furthermore, a total of forty-two adult normal male albino rats were included in this study, whereas one group was kept as the healthy control group (n = 6 rats) and diabetes was induced in the remaining animals (n = 36 rats) using alloxan injection (150 mg/kg of body weight). Among diabetic rats groups, a control group (n = 6 rats) was kept as the diabetic control group whereas the other 5 groups (6 rats per group) of diabetic rats were fed fermented camel milk (FCM) or fermented camel milk fortified with 1 and 1.5% of sage or mint leaves powder. Interestingly, the oral administration of fermented camel milk fortified with sage or mint leaves powder, at both concentrations, caused a significant decrease in blood glucose level and lipid profile, and an increase in insulin level compared to the diabetic control and FCM groups. Among others, the best results were observed in the group of animals that received fermented camel milk fortified with 1.5% sage powder. In addition, the results revealed that the fermented camel milk fortified with sage or mint leaves powder improved the liver and kidney functions of diabetic rats. Our study concluded that the use of sage and mint leaves powder (at a ratio of 1.5%) with fermented camel milk produces functional food products with anti-diabetic activity.

Effect of Lipid-Based Multiple Micronutrients Supplementation in Underweight Primigravida Pre-Eclamptic Women on Maternal and Pregnancy Outcomes: Randomized Clinical Trial.

Background and Objectives: In pre-eclampsia, restricted blood supply due to the lack of trophoblastic cell invasion and spiral artery remodeling is responsible for adverse pregnancies and maternal outcomes, which is added to by maternal undernutrition. This study was designed to observe the effect of multiple nutritional micronutrient supplements on the pregnancy outcomes of underweight pre-eclamptic women. To investigate the effects of lipid-based multiple micr supplementations (LNS-PLW) on pregnancy and maternal outcomes in underweight primigravida pre-eclamptic women. Materials and Methods: A total of 60 pre-eclamptic, underweight primigravida women from the antenatal units of tertiary care hospitals in the Khyber Pakhtunkhwa Province, Pakistan, were randomly divided into two groups (Group 1 and Group 2). The participants of both groups were receiving routine treatment for pre-eclampsia: iron (60 mgs) and folic acid (400 ug) IFA daily. Group 2 was given an additional sachet of 75 gm LNS-PLW daily till delivery. The pregnancy outcomes of both groups were recorded. The clinical parameters, hemoglobin, platelet count, and proteinuria were measured at recruitment. Results: The percentage of live births in Group 2 was 93% compared to 92% in Group 1. There were more normal vaginal deliveries (NVDs) in Group 2 compared to Group 1 (Group 2, 78% NVD; group 1, 69% NVD). In Group 1, 4% of the participants developed eclampsia. The frequency of cesarean sections was 8/26 (31%) in Group 1 and 6/28 (22%) in Group 2. The number of intrauterine deaths (IUDs) was only 1/28 (4%) in Group 2, while it was 2/26 (8%) in Group 1. The gestational age at delivery significantly improved with LNS-PLW supplementation (Group 2, 38.64 ± 0.78 weeks; Group 1, 36.88 ± 1.55 weeks, p-value 0.006). The Apgar score (Group 2, 9.3; Group 1, 8.4) and the birth weight of the babies improved with maternal supplementation with LNS-PLW (Group 2, 38.64 ± 0.78 weeks: Group 1, 36.88 ± 1.55; p-value 0.003). There was no significant difference in systolic blood pressure, while diastolic blood pressure (Group 2, 89.57 ± 2.08 mmHg; Group 1, 92.17 ± 5.18 mmHg, p-value 0.025) showed significant improvement with LNS-PLW supplementation. The hemoglobin concentration increased with the LNS-PLW supplement consumed in Group 2 (Group 2, 12.15 ± 0.78 g/dL; Group 1, 11.39 ± 0.48 g/dL, p-value < 0.001). However, no significant difference among the platelet counts of the two groups was observed. Conclusions: The pregnancy and maternal outcomes of underweight pre-eclamptic women can be improved by the prenatal daily supplementation of LNS-PLW during pregnancy, along with IFA and regular antenatal care and follow-up.

Zingiber officinale supplementation suppresses eimeriosis and regulates goblet cell response.

Coccidiosis affects both domestic and wild animals and negatively impacting industries worldwide. Medicinal plants are widely used against parasites. Using infected mice with Eimeria papillata, we assessed the anticoccidial impact of Zingiber officinale extract (ZE). The animals in the first group were just given distilled water, while the animals in the second group were given ZE. The parasite's oocysts were infected into the third and fourth groups. The fourth group was given ZE for five days. The oocysts in mice faeces were reduced after treatment with ZE. The total parasitic stages were reduced after treatments by about 50%. Also, gamonts, meronts and oocysts inside the jejunum were decreased after treatment with ZE. The infection caused hypoplasia of goblet cells of jejunum. ZE was able to ameliorate the goblet cells decrease. Behavioral response of animals to infection and treatment was investigated. All of these improvements could be attributed to the existence of active chemical classes of substances identified using infrared spectroscopy. Additional experiments are required to identify the phytochemical compounds in ZE and to understand their fighting mechanism against the parasite.

Myristica fragrans seed extract reverses scopolamine-induced cortical injury via stimulation of HO-1 expression in male rats.

Myristica fragrans, commonly known as nutmeg, belongs to the Myristicaceae family and is used as a spice and for its medicinal properties. The purpose of this study was to assess the neuroprotective effect of M. fragrans seed methanolic extract (MFE) on scopolamine-induced oxidative damage, inflammation, and apoptosis in male rat cortical tissue. MFE or N-acetylcysteine (NAC), a standard antioxidant drug, was administered 7 days before treatment with scopolamine resulted in high levels of malondialdehyde and nitric oxide (oxidative stress biomarkers), tumor necrosis factor-alpha and interleukin-1 beta (inflammatory mediators), and Bax and caspase-3 pro-apoptotic proteins. Additionally, scopolamine significantly depleted levels of glutathione (an antioxidant marker), Bcl-2 and c-FLIP (anti-apoptotic proteins), and antioxidant enzymes activity in cortical tissue. Scopolamine also enhanced acetylcholinesterase activity. MFE treatment protected the cortex of rats from the effects of scopolamine by reversing the effects on these toxicity markers. Interestingly, the neuroprotective effect of MFE was comparable to that exerted by the reference antioxidant NAC. Thus, our findings show that MFE has antioxidant, anti-inflammatory, and anti-apoptotic effects. The beneficial effects of MFE on scopolamine were partially mediated by promoting heme oxygenase 1 (Hmox1) expression and preserving cortical tissue structure.

Indigofera oblongifolia protects against trypanosomiasis-induced spleen injury.

BACKGROUND: Trypanosomiasis is a neglected tropical disease, transmitted by blood-sucking insects and can affect humans and animals, depending on the species of Trypanosoma parasite. Trypanosoma has acquired resistance to the majority of drugs used; hence, alternative medicines are required. Indigofera oblongifolia leaf extract (IOE) has been shown to treat blood stage malaria. Here, IOE was used to demonstrate its effect on Trypanosoma evansi-infected mice. METHODS: Analysis of IOE by gas chromatography-mass spectrometry showed the presence of many active components like flavonoids and phenolics. The mice were divided into three groups as follows: vehicle control, T. evansi-infected mice and T. evansi-infected-treated mice. RESULTS: The findings demonstrate a significant effect of IOE treatment on T. evansi-infected mice. Parasitemia was decreased by 70%, weight loss was reduced, and splenomegaly was significantly decreased. Additionally, IOE improved the histological architecture of the spleen, as shown by the improved histological injury score post-treatment. Anemia was apparent during the course of infection in T. evansi-infected mice; this was reversed upon treatment with IOE to almost the normal level of hemoglobin and erythrocytes. Reduced glutathione and catalase were also ameliorated upon IOE treatment compared to T. evansi-infected mice. CONCLUSION: Overall, this study shows the ameliorative role of IOE against T. evansi-induced spleen injury in mice.

Myristica fragrans Kernels Prevent Paracetamol-Induced Hepatotoxicity by Inducing Anti-Apoptotic Genes and Nrf2/HO-1 Pathway.

Paracetamol is responsible for acute liver failure in humans and experimental animals when taken at high doses and transformed into a reactive metabolite by the liver cytochrome P450. On the other hand, nutmeg is rich with many phytochemical ingredients that are known for their ability to inhibit cytochrome P450. Hence, the present experiment was aimed at studying the hepatoprotective effect of Myristica fragrans (nutmeg), kernel extract (MFKE) in respect to paracetamol (acetaminophen; N-acetyl-p-amino-phenol (APAP))-induced hepatotoxicity in rats, focusing on its antioxidant, anti-inflammatory, and anti-apoptotic activities. Liver toxicity was induced in rats by a single oral administration of APAP (2 g/kg). To evaluate the hepatoprotective effect of MFKE against this APAP-induced hepatotoxicity, rats were pre-treated with either oral administration of MFKE at 300 mg/kg daily for seven days or silymarin at 50 mg/kg as a standard hepatoprotective agent. APAP intoxication caused a drastic elevation in liver function markers (transaminases, alkaline phosphatase, and total bilirubin), oxidative stress indicators (lipid peroxidation and nitric oxide), inflammatory biomarkers (tumour necrosis factor-α, interleukin-1ß, inducible nitric oxide synthase, and nuclear factor ĸB) and the pro-apoptotic BCL2 Associated X (Bax) and caspases-3 genes. Furthermore, analyses of rat liver tissue revealed that APAP significantly depleted glutathione and inhibited the activities of antioxidant enzymes in addition to downregulating two key anti-apoptotic genes: Cellular FLICE (FADD-like IL-1ß-converting enzyme)-inhibitory protein (c-FLIP) and B-cell lymphoma 2 (Bcl-2). Pre-treatment with MFKE, however, attenuated APAP-induced liver toxicity by reversing all of these toxicity biomarkers. This hepatoprotective effect of MFKE was further confirmed by improvement in histopathological findings. Interestingly, the hepatoprotective effect of MFKE was comparable to that offered by the reference hepatoprotector, silymarin. In conclusion, our results revealed that MFKE had antioxidant, anti-inflammatory, and anti-apoptotic properties, and it is suggested that this hepatoprotective effect could be linked to its ability to promote the nuclear factor erythroid 2⁻related factor 2 (Nrf2)/antioxidant responsive element (ARE) pathway.

Ameliorative role of Ziziphus spina-christi leaf extracts against hepatic injury induced by Plasmodium chabaudi infected erythrocytes.

One of the most common deadliest parasitic diseases is Malaria. The biology and the pathogenesis of this fascinating parasite are not yet fully understood which make discovering effective alternative drugs a challenging task. Moreover, the emergence of resistant strains added an additional burden in the journey of malaria elimination. Traditional medicine used to be an alternative therapy choice owing to the presence of potent natural products. Ziziphus spina-christi (L.) considered being one of the common potent natural plant in gulf region and other nations. Therefore, this study designed to evaluate the ameliorative role of Z. spina-christi leaf extracts (ZSCLE) against Plasmodium chabaudi-induced hepatic injury. The study involved three groups were as follows; a vehicle control group, infected with 106 P. chabaudi-parasitized erythrocytes group and ZSCLE treated-infected mice with 106 P. chabaudi-parasitized erythrocytes group. The results showed a remarkable reduction of parasitemia level and notable reverse of the anemic picture among ZSCLE treated-infected mice. The effects of ZSCLE on the liver functions enzymes and on the histopathological pictures of liver were significant. It could be concluded that Z. spina-christi leaf extracts have a protective role against Plasmodium infection that also marked through significant restoration of hepatic oxidative markers.

Oxidative stress and genes regulation of cerebral malaria upon Zizyphus spina-christi treatment in a murine model.

The development and spread of multidrug-resistant strains of malarial parasites have led to an overwhelming increase in the resistance to current antimalarial drugs. The urgent need for alternative antimalarial drugs has directed some of the current studies toward folkloric medicine approaches. Interestingly, the Zizyphus spina Cristi leaf extract (ZLE) has been found to exhibit antiplasmodial activity. This study evaluated the protective effect of ZLE against Plasmodium berghei-induced cerebral tissue injuries in mice. Male C57Bl/6 mice received an injection of P. berghei-infected red blood cells. Mice were divided into three groups (control, infected, and ZLE-treated), and were subjected to histological, biochemical, and molecular analyses. Murine malaria infections induced significant weight loss; however, upon ZLE treatment, the weight of mice was markedly restored. Additionally, infected mice showed brain histopathological changes and induction of oxidative damage. Significantly, ZLE treatment restored the levels of oxidative markers and antioxidant enzyme to the normal ranges. The mRNA expression of several genes in the brain of mice including Cacnb4, Adam23, Glrb, Vdac3, and Cabp1 was significantly upregulated during P. berghei infection. In contrast, ZLE markedly reduced the mRNA expression of these genes. To conclude, the results indicate that ZLE could play an important role in reducing the destructive effect of P. berghei-induced cerebral malaria owing to its antiplasmodial and antioxidant activities.

Beneficial effect of Punica granatum peel extract on murine malaria-induced spleen injury.

BACKGROUND: Multiple drug-resistant malaria parasites have been widely detected, which has encouraged research studies focused on discovering alternative therapies. Medicinal plants such as pomegranate, Punica granatum, have been proven to exhibit antiprotozoal effects and therefore, we examined its effects on murine malaria-induced splenic injury and oxidative stress in this study. METHODS: Mice were divided into three groups, a vehicle control and two groups that were infected with 10(6) Plasmodium chabaudi-parasitized red blood cells (RBCs). The third group was gavaged with 100 µL of 300 mg/kg pomegranate peel extract for 6 days. All mice were euthanized on day 6 post-infection. RESULTS: The results revealed the potential antimalarial, antioxidant, and anti-inflammatory effects of pomegranate. Furthermore, pomegranate peel extracts significantly reduced parasitemia and spleen index of the treated mice compared to the untreated group. Additionally, the spleen histology score supported the findings by showing better amelioration in the pomegranate-treated mice than in the untreated mice. Concomitantly, the spleen capsule thickness showed clear evidence of splenomegaly in the untreated mice, as evidenced by the reduced spleen capsule. However, pomegranate peel extract exhibited a remarkable restorative effect on the spleen capsules of the treated mice. Moreover, the extract significantly reduced the expression levels of the proinflammatory cytokines interleukin (IL)-1ß, tumor necrosis factor (TNF)-α, and interferon (IFN)-γ as well as inducible nitric oxide synthase (iNOS). Moreover, our study showed that pomegranate extract profoundly affected oxidative stress levels by reducing the oxidant molecules, nitric oxide (NO) and malondialdehyde (MDA). CONCLUSION: This study showed that pomegranate clearly induced antimalarial activity in the host by attenuating inflammatory and oxidative stress responses. Furthermore, pomegranate enhanced the innate immune responses and, therefore, could serve an alternative therapy to control clinical malaria episodes and may protect against malaria infection.

The potential role of Punica granatum treatment on murine malaria-induced hepatic injury and oxidative stress.

Malaria is a health burden disease where the world harnessed the power of expertise and innovation to understand the biology of the parasite and the pathogenesis of the disease as well as to discover effective drugs. However, the treatment of malaria remains a challenging task and inadequate to address today's perplexing problem, the emergence of resistant strains. Historically, traditional medicine has been a mainstay for remediation and still retains its importance with the presence of potent natural products. Pomegranate has been used as antioxidant and anti-inflammatory against a range of diseases. Therefore, pomegranate peel extract (PPE) was used in this study to examine its effect on Plasmodium chabaudi-induced hepatic inflammation. Animals were allocated into three groups: a vehicle control group, a group infected with 10(6) P. chabaudi-parasitized erythrocytes and a pomegranate-treated group infected with 10(6) P. chabaudi-parasitized erythrocytes. This group received 100 µl of 300 mg/kg PPE after infection. The results showed the effectiveness of PPE on reversing the anaemic signs that have been provoked by P. chabaudi infection through instating the haemoglobin concentration and erythrocyte count back to normal values. Moreover, PPE exhibited hepatoprotective activities upon histopathological examination and liver function tests. These data were further confirmed by the significant reduction of the hepatic oxidative markers, glutathione, nitric oxide and malondialdehyde, in mice infected with P. chabaudi. Based on these outcomes, pomegranate could be used as a hepatoprotective agent against P. chabaudi-induced hepatic injury. However, further studies are needed in order to determine the mode of action of pomegranate upon infection.

A prospective evaluation of synergistic effect of sulbactam and tazobactam combination with meropenem or colistin against multidrug resistant Acinetobacter baumannii.

The present study evaluates the synergistic effect of sulbactam/tazobactam in combination with meropenem or colistin against multidrug resistant (MDR) Acinetobacter baumannii isolated from hospitalized patients from a tertiary care hospital in Saudi Arabia. During the study period, 54 multidrug and carbapenem-resistant isolates of A. baumannii isolates were collected from blood and respiratory samples of patients with ventilator-associated pneumonia or bacteremia. Microbroth checkerboard assay (CBA) and E-test were performed to look for synergistic interface of sulbactam and tazobactam with meropenem or colistin. All 54 MDR isolates of A. baumannii were resistant to carbapenem. Minimum inhibitory concentration [50/90] value against sulbactam, tazobactam, meropenem, colistin was found to be 64/128, 64/128, 64/256, and 0.5/1.0 respectively. Synergy was detected in more isolates with CBA compared to E-test. All four combinations showed significant synergistic bactericidal activity. However, the combination with colistin showed greater synergistic effect than combination with meropenem. Antagonism was not detected with any of the combinations and any method, but indifference was seen in tazobactam and colistin combination alone. A significant bactericidal effect was seen with sulbactam combination with meropenem or colistin in both methods. A combination therapy can be a choice of treatment. As colistin is known to exhibit nephrotoxicity, the combination of sulbactam and meropenem might be considered as an alternative antibiotic treatment for such multi- and extremely resistant bacteria. Yet, sample size is small in our study, so further well-designed in vitro and clinical studies on large scale should confirm our findings.

Metabolite footprinting of Plasmodium falciparum following exposure to Garcinia mangostana Linn. crude extract.

Multidrug resistant Plasmodium falciparum is the major health problem in the tropics. Discovery and development of new antimalarial drugs with novel modes of action is urgently required. The aim of the present study was to investigate antimalarial activities of Garcinia mangostana Linn. crude ethanolic extract including its bioactive compounds as well as the metabolic footprinting of P. falciparum following exposure to G. mangostana Linn. extract. The median (range) IC50 (concentration that inhibits parasite growth by 50%) values of ethanolic extract of G. mangostana Linn., α-mangostin, ß-mangostin, gartanin, 9-hydroxycarbaxathone, artesunate, and mefloquine for 3D7 vs K1 P. falciparum clones were 12.6 (10.5-13.2) vs 4.5 (3.5-6.3) µg/ml, 7.3 (7.1-8.5) vs 5.0 (3.7-5.9) µg/ml, 47.3 (46.8-54.0) vs 35.0 (30.0-43.7) µg/ml, 9.2 (8.1-11.9) vs 6.8 (6.2-9.1) µg/ml, 0.6 (0.4-0.8) vs 0.5 (0.4-0.7) µg/ml, 0.4 (0.2-1.2) vs 0.7 (0.4-1.0)ng/ml, and 5.0 (4.2-5.0) vs 2.7 (2.5-4.6) ng/ml, respectively. The action of G. mangostana Linn. started at 12 h of exposure, suggesting that the stage of its action is trophozoite. The 12-h exposure time was used as a suitable exposure time for further analysis of P. falciparum footprinting. G. mangostana Linn. extract was found to target several metabolic pathways particularly glucose and TCA metabolisms. The malate was not detected in culture medium of the exposed parasite, which may indirectly imply that the action of G. mangostana Linn. is through interruption of TCA metabolism.
