Introduction: Exposure to methyl methacrylate (MMA), which is a widely used monomer in dental and medical fields, has been shown to be associated with adverse health effects on liver. Aim: This study aims to evaluate the mechanism toxic effect of MMA on liver, via investigating alterations in the expression levels of inducible nitric oxide synthase (iNOS) and heat shock protein70 (HSP70) in the liver, subsequent to the oral administration of MMA in rats. Methods: 20 Sprague-Dawley female rats were randomly selected and divided into two groups: control group, and experimental group. The experimental group was orally administered 120 mg/kg of MMA daily 5 times per week for four weeks. Changes in the expression of HSP70 and iNOS in the liver tissue was investigated using Immunohistochemistry technique. Results: Exp group had statistcaly higher hepatic expression of iNOS (p < 0.01) in comparison to the control group, by approximately three folds. Similarly, rat hepatocytes in the experimental group showed statistically significant (p < 0.01) increase, by approximately 15 folds, in the expression of HSP70 compared to that in the control group. Conclusion: The presented data suggest that exposure to MMA might cause liver injury as indicated by the prominanat elevation of the oxidative stress biomarker iNOS and the biological stress biomarker HSP70.
3. Prevalence of Aspirin Resistance among Jordanian Patients with Cardiovascular Disease Eman Elayeh, Mohammad Mohammad, Mohammad Fararjeh, Eman Abu-Rish, Islam Hamad, Violet Kasabri, Amal Akour, Yasser Bustanji
Introduction: Despite the wide range of aspirin indications, there is a considerable amount of patients do not respond to aspirin, who also are referred to as aspirin non-responders or aspirin resistant patients. Aims and objectives: This study was carried out to prospectively evaluate the prevalence of aspirin resistance in Jordanian patients with cardiovascular disease and further clarify the clinical predictors of aspirin resistance. Materials and methods: Biochemical aspirin response was assessed based on the measurements of urinary11-dehydro thromboxane B2 (11-dhTxB2) levels using FDA approved diagnostic kit. Patients taking aspirin (75-325mg) for at least 7 days were prospectively enrolled from all stable cardiac patients presenting at Jordan University hospital outpatient clinics. Results: Eighty six (86) patients were enrolled in this study. Another twenty four healthy individuals were enrolled to function as a control group. The mean urinary levels of 11- dhTxB2/creatinine were significantly lower almost 3- times in patients in the primary and secondary aspirin prevention group compared with the control group (1567.58 vs. 4236.19 pg/mg, p-value <0.005). Thirty-one patients were found to be aspirin resistant with a prevalence of 36%. Conclusion: Our findings of aspirin resistance are particularly important given the large number of patients using this medication for prevention of atherothrombotic events. These results indicate that aspirin resistance should be diagnosed so that individuals with no response to aspirin can receive an alternative or an additional antiplatelet therapy.

The fruit of Capsicum annuum var. cerasiforme belonging to the Family Solanaceae is a widely used spice in Sikkim, a North Eastern state of India. The fruit of Capsicum annuum var. cerasiforme locally called ‘Dalle Khorsani’ is a valuable cash crop of Sikkim and also possess medicinal properties. Heracleum nepalense D. Don locally called ‘Chimphing’ belongs to the Family Umbillifereae and is extensively used in folk medicine. The present study evaluated the antimicrobial property of fruits of Capsicum annuum var. cerasiforme (Mill.) Irish and Heracleum nepalense D. Don using agar well diffusion method against Escherichia coli, Klebsiella pneumoniae,Pseudomonas aeruginosa, Proteus vulgaris, Staphylococcus aureus, Bacillus cereus and Bacillus subtilis. The antioxidant property of methanol extracts of fruits of these test plants was also investigated. The antioxidant property was evaluated by 2, 2-diphenyl-1-picryl hydrazyl (DPPH) free radical scavenging activity assay and Ferric reducing power assay. The total phenolic content was determined by using Gallic acid as a standard. The methanol extract of both the plants inhibited the growth of mostly Gram positive bacteria and Escherichia coli among Gram negative bacteria. However the acetone extract of the selected plants did not exhibit antimicrobial activity. The methanol extracts of these plants exhibited significant (p<0.05) concentration dependent increase in DPPH free radical scavenging activity. The extract of Capsicum annuum var. cerasiforme (Mill.) Irish also exhibited significantly higher (p<0.05) ferric reducing ability thereby showing higher antioxidant activity. The phytochemical analyses of the plant extracts revealed the presence of phenol, tannin, flavonoid, alkaloid, steroid and saponin. The results of the present study indicate that Capsicum annuum var. cerasiforme (Mill.) Irish and Heracleum nepalense D. Don can be a potential source of antimicrobial and antioxidant agents and can be explored further for its therapeutic use.

10. Rheumatoid Arthritis: History, Stages, Epidemiology, Pathogenesis, Diagnosis and Treatment Abeer Fauzi Al-Rubaye, Mohanad Jawad Kadhim, Imad Hadi Hameed
The pharmacological mechanisms of the medicinal plants traditionally used for RA in Persian medicine are discussed in the current review. Further investigations are mandatory to focus on bioefficacy of these phytochemicals for finding novel natural drugs. Rheumatoid arthritis is chronic, progressive, disabling autoimmune disease characterized by systemic inflammation of joints, damaging cartilage and bone around the joints. It is a systemic disease which means that it can affect the whole body and internal organs such as lungs, heart and eyes. Although numbers of synthetic drugs are being used as standard treatment for rheumatoid arthritis but they have adverse effect that can compromise the therapeutic treatment. Unfortunately, there is still no effective known medicinal treatment that cures rheumatoid arthritis as the modern medicine can only treat the symptoms of this disease that means to relieve pain and inflammation of joints. It is possible to use the herbs and plants in various forms in order to relieve the pain and inflammation in the joints. There are so many medicinal plants that have shown anti rheumatoid arthritis properties. So the plants and plant product with significant advantages are used for the treatment of rheumatoid arthritis. The present review is focused on the medicinal plants having anti rheumatoid arthritis activity.
11. Protective Effect of Moringa Oleifera Leaves Against Tramadol-Induced Nephrotoxicity in Mice Ashraf Albrakati
Tramadol, a broadly in recent years, is an effective analgesic agent for the treatment of moderate to acute pain. Its metabolites are excreted by the kidney which may cause nephrotoxicity. Moringa oleifera leaves are commonly used to provide herbal and plant-derived medicinal products especially in developing nations. The present study was carried out to determine the biochemical and histopathological changes in the kidney of tramadol-treated albino mice and to evaluate the possible protective role of Moringa oleifera leaves against tramadol-induced nephrotoxicity. Twenty adult albino mice were divided into four groups. Control group (group i) received daily intraperitoneal injection of normal saline only, group ii received oral dose of Moringa oleifera leaves extract (20 mg/kg/bw) for three weeks, group iii received daily intraperitoneal dose of tramadol (0.3 mg/kg/bw) for the same period, group iv, received daily oral dose of Moringa oleifera leaves extract, (20 mg/kg/bw) three hours before injecting intraperitoneal dose of tramadol (0.3 mg/kg/bw), for the same period. Blood samples were withdrawn at the end of the experiment for kidney function tests and specimens from the kidney were processed for histological study. No significant differences in the mean values of the kidney function tests were noticed between Moringa oleifera group and control group. However, there was highly significant increase in the mean values of serum, urea and creatinine in tramadol-treated group as compared to the control group. Although tramadol + Moringa oleifera group revealed significant difference in the mean values of urea and creatinine when compared with tramadol-treated group. So, Moringa oleifera leaves extract have been shown to attenuate the renal dysfunction, improve the renal architecture, with nearly normalization of serum urea and creatinine levels which indicate improvement of renal function. In conclusion, in the light of biochemical results and histological findings, co-administration of Moringa oleifera leaves lessened the negative effects of tramadol-induced nephrotoxicity; possibly by its antioxidant action. Further investigation of these promising protective effects of Moringa oleifera leaves against tramadol-induced renal injury may have considerable impact on developing an adjunct therapy aiming to improve the therapeutic index of some nephrotoxic drugs.
12. Protective Effects of Indonesian Propolis Against Light-Induced Retinal Damage Paula M. Kustiawan, Hiroyuki Okuyoshi, Yoshiki Kuse, Hiroshi Izawa, Yuichi Saito, Kazuhiro Tsuruma, Chanpen Chanchao, Hideaki Hara, Masamitsu Shimazawa
The pharmacological and biological activities of Indonesian propolis are mostly unexplored except for its anticancer properties. This study was designed to explore the protective effects of the methanol extract of Indonesian propolis (MEP) obtained from the stingless bee (Trigona incisa) against light-induced retinal photoreceptor damage. Murine photoreceptor (661W) cells were cultured and treated with MEP. The cells were exposed to cellular stress inducers such as tunicamycin, hydrogen peroxide, and light irradiation. The protective effects of MEP were assessed by determining production of intracellular reactive oxygen species (ROS), analyzing changes in nuclear factor-kappa B (NF-κB) level, analyzing caspase-3/7 activation, and by using the zebrafish retinal degeneration model. MEP significantly reduced cell death induced by tunicamycin, hydrogen peroxide, and white light irradiation in a concentration-dependent manner. The phosphorylation of NF-κB decreased and light-induced activation of caspases-3/7 and intracellular accumulation of ROS were inhibited. The thickness of outer nuclear layer (ONL) in zebrafish retina significantly increased following MEP treatment. The MEP obtained from stingless bee propolis has a protective effect on photoreceptor retinal cells and has the potential to be developed as a supplement in prevention of retinal diseases.
