Raw264.7 Cell

The exosome excreted by RAW264.7 cell was found to participate in the damage of lung function. Our purpose was to assess the exact mechanism. The animal experiment was adopted in our study. It was provided reference for clinical experiment. 30 healthy male rats were selected and assigned into normal control group, normal exosome group and LPS with exosome group by random number table followed by analysis of the size and form of exosome under electron microscope, the lung structural change by hematoxylin and eosin staining, TNF-α and IL-1β secretion by immunohistochemistry, and the expression of tightly bound protein one (ZO-1), closed protein, β-chain protein and two groups of exosome-marked protein (CD9 and CD63) by western blot. In normal control group, the lung structure was very integral with clear alveolar space. The cell wall was smooth relatively without exudation substance in alveolar space and mesenchyme. Normal exosome group showed relatively integral lung structure and thicker cell wall. The inside of alveolar space was very clear without exudation substance in alveolar space and mesenchyme. LPS + exosome group presented abundant inflammatory cells in alveolar space and mesenchyme with obvious bleeding. Inflammatory factor secretion such as TNF-α (1.334 ± 0.205%) and IL-1β (0.803 ± 0.097%)was significantly higher and the content of closed protein (0.203 ±0.017%) was lower in LPS with exosome group than the other two groups (P < 0.05). The exosome secreted by RAW264.7 cell after stimulation by lipopolysaccharide could impair the lung function in rats and is related with the decline of closed protein.

Cordyceps militaris (CM), a valuable edible and medicinal fungus, has been used as traditional medicine to treat health conditions, as well as hyposexuality in Asian societies for over a century. Due to the high demand, several artificial cultivation methods have been developed for their biological activities. In this study, CM was cultured on medium that contained white rice and silkworm pupae, and the levels of cordycepin and adenosine, as well as its aphrodisiac effects in diabetes-induced erectile dysfunction (DIED), were evaluated. Diabetic rats were induced by streptozotocin (STZ) injection and administered orally with CM (0.1, 0.5, and 1.0 g/kg BW/day) for 3 weeks. Diabetic rats in negative and positive control groups received vehicle and sildenafil citrate (5 mg/kg), respectively. Results showed the changes in mating behaviour in which mount latency and intromission latency were significantly increased in diabetic rats, compared with the normal control group. Diabetic rats also showed a significant reduction in intracavernosal pressure (ICP) response to cavernous nerve stimulation, sperm count, testosterone level, penile nitric oxide synthase (NOS), and testicular superoxide dismutase (SOD) activities, when compared to the normal control group. Administration of CM (0.1, 0.5, and 1.0 g/kg BW/day) reversed the effects of diabetes on the mating behaviour, and the ICP responses to electrical stimulation. Moreover, the levels of penile NOS, testicular SOD activities, testosterone, and sperm count were significantly increased, and testicular malondialdehyde (MDA) levels were significantly decreased in these treated diabetic rats. Diabetic rats treated with sildenafil showed a significant induction in intromission frequency and NOS and SOD activities, as well as a marked increase in ICP responses. These results suggest that CCM exerts its aphrodisiac effect, possibly through activating testosterone production and suppressing oxidative stress to enhance erectile function in diabetic rats.

Hydroethanolic Extract

Abstract Aim evaluate antioxidant and anti-anaemia activity of dichloromethane, hydroethanolic, and alkaloids-free hydroethanolic extracts of beetroot (Beta vulgaris (L.) subsp. vulgaris) on phenylhydrazine-induced rats. Methods Male rats were divided into five groups: normal control group, negative control group, dichloromethane extract group, hydroethanolic extract group, and alkaloids-free hydroethanolic extract group. All groups were induced with phenylhydrazine (30 mg.Kg−1 BW) for three days, except for the normal control group. After induction, each treatment group received each extract (200 mg.Kg−1 BW) for 21 days. The haematology parameters (haemoglobin levels, the number of erythrocytes, and haematocrit levels) were measured using Haematology Analyzer, and the antioxidant activity was measured through MDA level parameters in rats. Data were analysed using one-way ANOVA and then continued with the Tukey test. Results The results showed that the hydroethanolic extract of beetroot increased the percentage of erythrocytes (33.5%), haemoglobin (25%), and haematocrit (24.4%) to the negative control group, which was comparable to the normal control group (p > 0.05). In addition, the best antioxidant activity was shown in the hydroethanolic extract of beetroot, which is comparable to the normal group (p > 0.05). Conclusion The beetroot hydroethanolic crude extract could be potentially produced in a natural pharmaceutical product as a beneficial resource within anti-anaemia and antioxidant activities.

Background: Nitrosamines as a carcinogenic agent has unfavorable effects on some of the male reproductive parameters. Pentoxifylline (PX) is a xanthine derivative used as a drug inhibiting the inflammatory factors, reducing blood viscosity, improving peripheral blood flow, and so on. Objective: The aim of the present study is to evaluate the effects of PX against Dimethyl nitrosamine (DMN)-inducing the damage to the reproductive parameter of male rats. Materials and Methods: In this experimental study, 48 male Wistar rats (8 wk, 220- 250 gr) were randomly assigned to eight groups (n = 6/each): normal control and DMN control groups (40 mg/kg); PX groups (25, 50, 100 mg/kg), and DMN + PX groups (25, 50, 100 mg/kg). Treatments were administered intraperitoneally and the gavage applied daily for 28 days. The sperm parameters, spermatogenesis index, total antioxidant capacity, testosterone level, and seminiferous tube diameter were assessed. Results: The values of all parameters reduced significantly in the DMN control group compared to the normal control group (p < 0.001). The PX and PX + DMN treatments at all entirely doses improved all parameters significantly compared to the DMN control group (p < 0.001). Conclusion: DMN caused detrimental effects on reproductive parameters. Also, no significant modifications were observed in PX treatments at all doses compared to the normal control group. PX compensated the toxic effect of DMN on reproductive parameters. Key words: Dimethyl nitrosamine, Reproductive, Pentoxifylline, Rat.

Objective: Excessive oxidative stress is implicated in spleen injury. Platelet-rich plasma (PRP) and quercetin (QUR) have been shown to protect cells against oxidative stress. This study was designed to investigate their effect on dimethyl nitrosamine (DMN) induced spleen injury in male rats. Methods: Forty male Wistar rats were divided into four groups; Group (1): Negative control group (Con), Group (2): DMN group, DMN was given intraperitonealy at a dose of 4 mg/kg b. wt/day for four weeks for sub-chronic injury of spleen tissue, Group (3): DMN+PRP, rats were injected intraperitonealy with DMN at a dose of 4 mg/kg b. wt/day for four weeks then treated i. v. by single dose 50 μL of PRP, then left for a period of four weeks without any treatments, Group(4): DMN+QUR, rats received intraperitonealy DMN at a dose of 4 mg/kg b. wt/day for four weeks, then treated with quercetin orally at a dose of 50 mg/kg b. wt. in aqueous suspension daily using an intragastric tube for four weeks. Results: DMN inoculation resulted in significant elevations of oxidative stress, as evidenced by the increased malondialdehyde, hydrogen peroxide and xanthine oxidase levels associated with a significant decrease in Superoxide dismutase and catalase activities in the spleen tissue as compared to the normal control group. Moreover, DMN caused an up-regulation in the values of the splenic C-reactive protein (CRP), interleuckin-6 (IL-6), nuclear factor kappa B (NF-κB), leukotriene-C4 (LT-C4), P53 and Fas levels with a significant decline in anti-apoptotic protein B-cell lymphoma 2 level as compared to the normal control group. PRP and QUR significantly attenuated the DMN-evoked spleen oxidative stress and modulated the activities of antioxidant enzymes as compared to DMN group. In addition, treatment of DMN group with PRP or QUR resulted in an improvement in CRP, IL-6, NF-κB, LT-C4, P53 and Fas levels as compared to DMN group. Caspase-3 expression was positive in DMN group while no difference was present in control, PRP and Quercetin groups. However, the VEGF immunopositive reaction was found in DMN, PRP and Quercetin groups compared to control group. Histopathological results showed degeneration, haemorrhage, inflammatory cells and necrotoic areas in splenic tissue from DMN group compared to the treated groups where signs of recovery were observed in the whole splenic tissue. Conclusion: These data suggest that PRP and QUR protect rat spleen from DMN-induced oxidative stress, probably via their antioxidant activity, anti-inflammatory and anti-apoptotic effects. So, PRP and QUR are promising pharmacological agents for preventing the potential spleen injury of DMN following occupational or environmental exposures.

AbstractStroke is a sudden cerebrovascular circulatory disorder with high morbidity, disability, mortality, and recurrence rate, but its pathogenesis and key genes are still unclear. In this study, bioinformatics was used to deeply analyze the pathogenesis of stroke and related key genes, so as to study the potential pathogenesis of stroke and provide guidance for clinical treatment. Gene Expression profiles of GSE58294 and GSE16561 were obtained from Gene Expression Omnibus (GEO), the differentially expressed genes (DEGs) were identified between IS and normal control group. The different expression genes (DEGs) between IS and normal control group were screened with the GEO2R online tool. The Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses of the DEGs were performed. Using the Database for Annotation, Visualization and Integrated Discovery (DAVID) and gene set enrichment analysis (GSEA), the function and pathway enrichment analysis of DEGS were performed. Then, a protein–protein interaction (PPI) network was constructed via the Search Tool for the Retrieval of Interacting Genes (STRING) database. Cytoscape with CytoHubba were used to identify the hub genes. Finally, NetworkAnalyst was used to construct the targeted microRNAs (miRNAs) of the hub genes. A total of 85 DEGs were screened out in this study, including 65 upward genes and 20 downward genes. In addition, 3 KEGG pathways, cytokine − cytokine receptor interaction, hematopoietic cell lineage, B cell receptor signaling pathway, were significantly enriched using a database for labeling, visualization, and synthetic discovery. In combination with the results of the PPI network and CytoHubba, 10 hub genes including CEACAM8, CD19, MMP9, ARG1, CKAP4, CCR7, MGAM, CD79A, CD79B, and CLEC4D were selected. Combined with DEG-miRNAs visualization, 5 miRNAs, including hsa-mir-146a-5p, hsa-mir-7-5p, hsa-mir-335-5p, and hsa-mir-27a- 3p, were predicted as possibly the key miRNAs. Our findings will contribute to identification of potential biomarkers and novel strategies for the treatment of ischemic stroke, and provide a new strategy for clinical therapy.

Abstract Purpose: Lung adenocarcinoma (LUAD) has high heterogeneity and poor prognosis, posing a major challenge to human health worldwide. Therefore, it is necessary to improve our understanding of the molecular mechanism of LUAD in order to be able to better predict its prognosis and develop new therapeutic strategies for target genes.Methods: The Cancer Genome Atlas and Gene Expression Omnibus, were selected to comprehensively analyze and explore the differences between LUAD tumors and adjacent normal tissues. Critical gene information was obtained through weighted gene co-expression network analysis (WGCNA), differential gene expression analysis, and survival analysis.Results: Using WGCNA and differential gene expression analysis, 29 differentially expressed genes were screened. The functional annotation analysis showed these genes to be mainly concentrated in heart trabecula formation, regulation of inflammatory response, collagen-containing extracellular matrix, and metalloendopeptidase inhibitor activity. Also, in the protein–protein interaction network analysis, 10 central genes were identified using Cytoscape's CytoHubba plug-in. The expression of CDH5, TEK, TIMP3, EDNRB, EPAS1, MYL9, SPARCL1, KLF4, and TGFBR3 in LUAD tissue was found to be lower than that in the normal control group, while the expression of MMP1 in LUAD tissue was higher than that in the normal control group. According to survival analysis, the low expression of MYL9 and SPARCL1 was correlated with poor overall survival in patients with LUAD. Finally, through the verification of the Oncomine database, it was found that the expression levels of MYL9 and SPARCL1 were consistent with the mRNA levels in LUAD samples, and both were downregulated.Conclusion: Two survival-related genes, MYL9 and SPARCL1, were determined to be highly correlated with the development of LUAD. Both may play an essential role in the development LUAD and may be potential biomarkers for its diagnosis and treatment in the future.

This study was carried out to ascertain the hepatotoxic potential of T.daniellii (T.d) and A. cordifolia (A.c). Investigations were conducted using standard methods. Oral administration of 200mg/kg aqueous leaf extracts of T.daniellii caused a non-significant increase in the activity of ALT (5.43±0.60IU/L), AST (16.93±0.26 IU/L) and ALP (160.70±1.04 IU/L) compared to the values recorded on the normal control (group I) ALT (3.84±0.16 IU/L), AST (14.19±0.52 IU/L) and ALP (157.26±0.64 IU/L). Group III administered with 200mg/kg methanolic leaf extract of T. daniellii manifested a significant elevation in the activity of ALT (13.15±0.89 IU/L), AST (22.84±0.38 IU/L) and ALP (170.40±0.44 IU/L) compared to the normal control. Similarly, groups IV and V which were orally administered with 200mg/kg aqueous and methanolic leaf extracts of A. cordifolia showed significant increase in the activity of ALT (6.32±0.33U/L), AST (17.70±0.030U/L) and ALP (161.13±0.09U/L) and ALT (7.55±0.59U/L), AST (19.35±0.26U/L) and ALP (165.38±0.35U/L) respectively compared to the values recorded on the control (group I). In conclusion, drug development protocols involving T. daniellii leaf should preferably use water as an ideal solvent. On the other hand, the hepatotocity associated with both aqueous and methanolic extracts of A. cordifolia could imply the presence of hepatotoxins in the leaf of the said plant.

Objective: The aim of the present study leads a comparative assessment of the toxicological profile of PEGylated fourth and fifth-generation poly (propylene imine) dendrimers (PPI). Methods: 4.0G and 5.0G generations of PPI dendrimer were synthesized and PEGylated with Mono polyethylene glycol 5000 (MPEG-5000). Each PEGylated 4.0G and 5.0G dendrimeric generation were administered in three different doses: 2.5 mg/kg, 25 mg/kg and 250 mg/kg (i.e., low, intermediate and high dose) to wister rats. After the dose administration, the blood and tissue samples of wister rats were collected after 24 h and 15 d after. All the collected samples were proceeded for hematological, biochemical and histopathological studies. Results: After 24 h of (250 mg/kg) dose administration PEGylated 5.0G PPI dendrimer the RBC count, hemoglobin content and WBC count were found 7.873±0.129 mill/cmm, 13.833±0.491g/dl and 9033.33±2384.906 mill/cmm, while PEGylated 4.0G PPI dendrimer indicated RBC count, hemoglobin content and WBC count 8.733±0.239 mill/cmm, 14.033±0.12 g/dl and 9666.667±2567.316 mill/cmm, in blood samples as compare to RBC count 9.346±0.037 mill/cmm, hemoglobin content 15.35±0.15 g/dl and WBC count 8500±286.675 mill/cmm of the animals of normal control group. Thus there are no remarkable changes (p>0.05) in RBC count, hemoglobin content and other hematological profile after 24 h in comparison of normal control group of animals. Similarily insignificant changes (p>0.05) in serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT), lactate dehydrogenase (LDH) and sections of different organs indicate inoffensive nature of both generations of PEGylated 4.0G and 5.0 G PPI dendrimers. Conclusion: It can be concluded that fifth-generation PPI dendrimers are more suitable as compared to fourth generation of PPI dendrimer, while both dendrimers are not generating any severe toxicity.
