Four rhizobacteria selected out of over 500 isolates from rhizosphere of the vegetables in China were further studied for suppression of the root-knot nematode and soil-borne fungal pathogens in laboratory and greenhouse in Belgium. They were identified as Brevibacillus brevis or Bacillus subtilis by Biolog test and partial 16s rDNA sequence comparison. They not only inhibited the radial growth of the root-infecting fungi Rhizoctonia solani SX-6, Pythium aphanidermatum ZJP-1 and Fusarium oxysporum f.sp. cucumerinum ZJF-2 in vitro, but also exhibited strong nematicidal activity by killing the second stage larvae of Meloidogyne javanica to varying degrees in the greenhouse. The toxic principles of bacterium B7 that showed the highest juvenile mortality were partially characterized. The active factors were heat stability and resistance to extreme pH values. B7 used either as seed dressing or soil drench significantly reduced the nematode populations in the rhizosphere and enhanced the growth of mungbean plants over the controls in the presence or absence of R. solani.

Objective:
To examine the effect of coadministration of different medicinal plant extracts (curcumin and extracts of Nigella sativa L. [N. sativa, Jia Hei Zhong Cao], Zingiber officinale Rosc. [Z. officinale, Sheng Jiang], and Punica granatum L. [P. granatum, Shi Liu]) with spiramycin (SP) against the cystogenic ME-49 Toxoplasma gondii (T. gondii) strain in immunocompromised mice.
Methods:
We utilized 68 mice categorized into 8 groups: 2 non-infected controls (immunocompetent and immunocompromised), 1 infected control, and 5 infected and treated groups. Following the experiment, the cerebral tissues of each mouse underwent parasitological, histopathological, and immunohistochemical evaluations.
Results:
Compared with the infected non-treated group, all infected treated groups showed significant reductions in brain cyst numbers (all P < .05), with the highest reduction rate (77.4%) recorded for P. granatum and SP combination (G8). Only G8 showed a significant reduction in mouse deaths compared with the other groups. With regards to restoring histopathological changes and decreasing inflammation, the groups infected and treated with curcumin and P. granatum combined with SP showed the best results (P < .05). Combinations of curcumin and extracts of Z. officinale and P. granatum with SP significantly restored the cerebral expression of caspase-3 compared with the N. sativa extract combination (P < .05). G8 showed non-significant expression compared with the local expression in the negative control groups.
Conclusion
Our study revealed that the coadministration of P. granatum extract with SP was the most effective combination against chronic cerebral toxoplasmosis.

The hepatoprotective activity of the ethanol extract of Astragalus kahiricus (Fabaceae) roots against ethanol-induced liver apoptosis was evaluated and it showed very promising hepatoprotective actions through different mechanisms. The extract counteracted the ethanol-induced liver enzymes leakage and glutathione depletion. In addition, it demonstrated anti-apoptotic effects against caspase-3 activation and DNA fragmentation that were confirmed by liver histopathological examination. Moreover, the phytochemical study of this extract led to the isolation of four cycloartane-type triterpenes identified as astrasieversianin II (1), astramembrannin II (2), astrasieversianin XIV (3), and cycloastragenol (4). The structures of these isolates were established by HRESI-MS and 1D and 2D NMR experiments. The antimicrobial, antimalarial, and cytotoxic activities of the isolates were further evaluated, but none of them showed any activity.

Objective:
To develop a set of quality indicators (QIs) tailored to improve the care provided to children with juvenile idiopathic arthritis (JIA) in countries across the Asia-Pacific region.
Methods:
An adaptation of the Research and Development Corporation (RAND)/University of California, Los Angeles (UCLA) Appropriateness Method (RAM) was used. An initial set of 32 QIs was developed after a systematic search of the literature. These were presented to members of a Delphi panel composed of pediatric rheumatologists and other relevant stakeholders from the Asia Pacific League of Associations for Rheumatology Pediatric Special Interest Group (APLAR-Pediatric SIG). After each round, the mean scores for validity and reliability, level of disagreement, and median absolute deviation from the mean were calculated.
Results:
The panelists were presented with 32 QIs in two rounds of voting, resulting in the formulation of a final set of 22 QIs for JIA. These QIs are categorized within six domains of care, including access to care, clinical assessment, medications and medication monitoring, screening for comorbidities, counseling, and self-efficacy and satisfaction with care.
Conclusion
These QIs have been developed to evaluate and improve the quality of care provided to children with JIA, aiming to enhance health outcomes and ensure that healthcare services are tailored to the unique needs of this patient population.

Objective: To investigate the neuroprotective efficacy of pomegranate and ellagic acid on the histopathological changes in the hippocampus of an aluminium chloride (AlCl3) induced rat model of Alzheimer's disease. Methods: Sprague Dawley rats were divided into 4 groups (n=10 each): Group I : serving as negative control; Group II, Alzheimer model, induced by administration of 17 mg/kg bw AlCl3; Group III, administered the same dose of AlCl3 with 50 mg/kg of pomegranate peel extract and Group IV : administered ellagic acid (50 mg/kg) in addition to the same dose of AlCl3. The medication given to all groups continued for 28 days. All were given the compounds by gastric gavage. Radial arm maze test, hippocampus antioxidant markers, histopathology of the dentate gyrus, and CA3 of the hippocampus were evaluated. Results: Rats treated with pomegranate peel extract exposed to radial arm maze test showed less number of errors and reduced time needed to reach the criterion. There was an increase in the levels of glutathione, catalase, and total antioxidant capacity and decreased lipid peroxidation products. Histopathological features in dentate gyrus and CA3 as apoptosis and chromatolysis of pyramidal cells and granular layer, respectively, were decreased. Alzheimer characteristic neurofibrillary tangles and senile plaques were reduced. Treatment with ellagic acid ameliorated the pathological results but to a statistically lower level. Conclusions: Pomegranate peel extract alleviates memory deficit and restores antioxidant homeostasis following degenerative changes in the hippocampus induced by aluminium chloride in rats..

Objective: To evaluate the effect of Moringa oleifera leaf ethanol extract as an adjunct treatment on lead acetate induced hepato-nephrotoxicity in rabbits. Methods: Thirty-six male New Zealand White rabbits were assigned into two main groups. The first group (14 rabbits) served as normal control. The secondgroup (22 rabbits) was administered orally with lead acetate at a dose of 40 mg/kg/day, 5 days/week for 8 weeks. At the 4th and the 8th week of treatment, 6 animals (3 animals at each period) of the second group were sacrificed while the remaining animals (16 rabbits) were assigned randomly into 2 subgroups (8 rabbits each): treated and non-treated. The first subgroup was orally given 1 mL phosphate-buffered saline for further 4 weeks while the second subgroup was administered orally with Moringa oleifera leaf ethanol extract at a dose of 400 mg/kg/day for the same period. Blood samples were collected to determine hematological and serum biochemical indices. Tissue specimens were collected from the liver and kidney for evaluation of the oxidant/antioxidant markers and for histopathological examinations. Results: Lead acetate exposure decreased the mean body weight gain, hematocrit, hemoglobin, mean corpuscular volume, and lymphocytes count. Moreover, it markedly increased counts of monocytes and platelets, serum enzyme activity, levels of creatinine, total cholesterol, triglycerides, and low-density lipoprotein cholesterol. Malondialdehyde level was markedly increased while the reduced glutathione content was significantly decreased in liver tissue of lead intoxicated-rabbits. Histopathological alterations were also noticed in the liver and kidney of lead intoxicated rabbits. Moringa oleifera leaf ethanol extract significantly improved hematological and serum biochemical parameters and histopathological structure of the liver and kidney. Conclusions: Moringa oleifera leaf ethanol extract ameliorates hemato-biochemical and histopathological alterations caused by lead acetate and improveshepatic and renal functions.

Objective: To analyze the phytochemical constituents, and to explore potential protective effect of the methanol extract of Moringa oleifera (M. oleifera) seeds and Egyptian propolis, each alone or concurrently administered on acetic acid-induced ulcerative colitis in rats. Methods: Eight groups of 5 rats each were used: normal control group with distilled water, model group, two groups with M. oleifera seeds (100 and 200 mg/kg), two groups with propolis (50 and 100 mg/kg), one group with concurrent administration of both, and one group with prednisolone (reference drug). Macro-and microscopic picture, ulcer index and lesion scores, oxidative markers, inflammatory mediators, in vitro activity of the inflammatory enzymes and 1, 1-diphenyl-2-picrylhydrazyl free radicals scavenging activity were evaluated. The phytochemical constituents of both extracts were explored by GC-MS analysis. Results: Both treatments modulated the macro-and microscopic picture, decreased the ulcerative index, lesion score, oxidative markers and inflammatory mediators, and inhibited the COX-1 and COX-2 enzymes. Propolis appeared to be powerful free radicals scavenger. A powerful synergistic effect of both treatments in modulating the course of the disease was reported. GC-MS analysis of methanol extract of M. oleifera seeds and propolis revealed the presence of 50 and 34 compounds, respectively. Conclusions: M. oleifera seeds and propolis methanol extracts have modulated the course of acetic acid-induced ulcerative colitis. Moreover, both treatments induce a good synergistic effect against the disease. Isolation of the active constituents is recommended.
