Renoprotective effects of the methanolic extract of Tanacetum parthenium against carbon tetrachloride-induced renal injury in rats
Objective: Studies have demonstrated that carbon tetrachloride (CCl4) increases the generation of reactive oxygen species (ROS) in many tissues including the kidney, heart, lung, brain, and liver. The major aim of the present study was to evaluate the protective activity of Tanacetum parthenium extract (TPE) in renal tissues of CCl4-intoxicated rats. Materials and Methods: Animals were divided into seven groups of six rats. Group 1 was the control group that was not treated with CCl4. The rats in the other groups were intraperitoneally injected with CCl4 (1.5 ml/kg, 1:1 in olive oil) on day 14. Rats in the groups bTPE40, bTPE80, and bTPE120 were gavaged with 40, 80, and 120 mg/kg of TPE, respectively for 14 constitutive days on a daily basis, before CCl4 administration. Rats in groups aTPE80 and aTPE120 were gavaged with 80 and 120 mg/kg of TPE, respectively, 2, 6, 24 and 48 hr after receiving CCl4. Blood samples were collected at the end of the 16th day through an intracardiac puncture and then serums were separated. Results: CCl4 increased urea, creatinine, uric acid and creatinine: albumin (C/A) ratio level in serum and decreased total antioxidant and antioxidant enzymes (SOD and GPx) when compared to the control group (

Feverfew attenuates carbon tetrachloride-induced testicular damage in rats
Introduction: Feverfew is an herbal medicine with the traditional usage of treating several disorders. Some investigations have demonstrated that feverfew is an effective remedy for the prophylactic treatment of inflammatory conditions, migraine and menstrual disorders. Therefore, this study was arranged out to evaluate the protective or curative potentials of feverfew methanolic extract (FME) on carbon tetrachloride (CCl4) induced oxidative trauma in testis. Methods: In this experiment, male Wistar rats were divided into seven groups (n=6). Group I as a normal control received 1 mL/kg distilled water for 14 days orally and on the 14th-day olive oil (1.5 mL/kg, i.p.). Group II received 1 mL/kg distilled water orally for 14 consecutive days. Groups III, IV and V animals were pretreatment groups and treated with three different doses of FME (40, 80, and 120 mg/kg, p.o, respectively) for 14 days. All groups except group one, were also intoxicated with 1.5 ml CCl4 (i.p, in a 1:1 dilution with olive oil) on the 14th day. Groups VI and VII were post-treatment groups and received FME (80 and 120 mg/kg, p.o, respectively) at 2, 6, 24 and 48 h after CCl4 injection. Results: Injection of CCl4 significantly (P < 0.001) reduced antioxidant enzymes (SOD and GPx) and increased malondialdehyde when compared to the control group. Administration of FME significantly (P < 0.05) improved these alterations near to control rats. Conclusion: It is suggested that FME has the ability to protect testis against oxidative damage, possibly through antioxidant effects of its bioactive compounds

Surgical Closer of Atrial Septal Defect in Adults after 40 Years Old
Objective: Atrial septal defect (ASD) is the most common congenital heart disease in adults. The aim of
this study was to determine the value of surgical closure of ASD in patients over 40 years of age.
Materials and Methods: Retrospective analysis of 96 patients with the mean age of 47.58 ± 6.59, who had
undergone surgical repair of ASD, was carried out. Pre and postoperative clinical status, New York Heart
Association (NYHA) functional class and systolic pulmonary artery pressure before and after surgical
repair, complications of post operation were assessed and analyzed. The follow-up period was between 1
month and 16 years.
Results: Before the operations, 62 patients (89.8%) were placed in NYHA functional classes of II and III.
However, after the surgeries most of the patients could be placed in the functional classes I and II. The
mean of pulmonary artery pressure before the surgeries was about 46.68 ± 14.18 and dropped to 32 ± 11.89
mm Hg after the operations (P < 0.0001). Atrial fibrillation rhythm was present in 18 cases preoperatively
which was reduced to 3 patients at the discharge time (16.6%). The mean right ventricular (RV) sizes were
reduced from 4.1 to 2.5 cm after the surgical repairs. In 35 cases (36.64%), we had no tricuspid valve
regurgitation after surgery for RV systolic presser estimation.
Conclusion: Surgical closure of ASD in patients over 40 years of age could improve their clinical status,
and lead to a reduced pulmonary systolic as well as smaller RV sizes
The Synergistic Effects of Hydroalcoholic Extracts of Cinnamon and Ginger on the Biochemical Parameters of CCl4-Intoxicated Rats
Background & objectives: Considering the importance of liver toxicity due to drugs and toxins as a major cause of liver damage, this study was conducted to evaluate the effects of the combination of cinnamon and ginger extracts on serum biochemical parameters in carbon tetrachloride (CCl4)- intoxicated rats.
 Methods: In this experimental study, forty-two male Wistar rats were divided into 7 groups (n=6). Three control groups including normal control, combined extract control and damaged control were designated that received distilled water, a mixture of cinnamon and ginger extracts and distilled water respectively for 14 days.
 Other 4 groups were pre-treatment groups which were treated with cinnamon (50 mg/kg/d), ginger (250 mg/kg/d), cinnamon + ginger (25+125 mg/kg/d) and silymarin (100 mg/kg/d) respectively for 14 days before being damaged by intraperitoneal injection of CCl4 (1 ml/kg, 1:1 in olive oil). Fifty - two hours after CCl4 injection, blood sampling was performed and biochemical parameters were measured in serum of rats.
Results: The results of this study showed that the injection of CCl4 significantly increased the ALT and AST enzymes activity ,cholesterol, triglyceride, and LDL levels and decreased the blood albumin and HDL levels in damaged rats compared to the normal control group (p<0.001). However, pre-treatment with the cinnamon and ginger extracts, especially combination of extracts significantly improved these values ​​compared to the CCl4 damage group (p<0.001).
Conclusion: The results suggest that simultaneous use of cinnamon and ginger extracts has more significant protective effects against CCl4-induced hepatotoxicity
Cytotoxic Effects of Newly Synthesized Palladium(II) Complexes of Diethyldithiocarbamate on Gastrointestinal Cancer Cell Lines
As a part of a drug development program to discover novel therapeutic and more effective palladium (Pd) based anticancer drugs, a series of water-soluble Pd complexes have been synthesized by interaction between [Pd (phen)(H2O)2(NO3)2] and alkylenebisdithiocarbamate(al-bis-dtc) disodium salts. This study was undertaken to examine the possible cytotoxic effect of three novel complexes (0.125–64 µg/mL) on human gastric carcinoma (AGS), esophageal squamous cell carcinoma (Kyse-30), and hepatocellular carcinoma (HepG2) cell lines. The cytotoxicity was examined using cell proliferation and acridine orange/ethidium bromide (AO/EB) assay. In order to examine the effects of new Pd(II) complexes on cell cycle status, we performed cell cycle analysis. The complexes were found to have completely lethal effects on the cell lines, and the half maximal inhibitory concentration (IC50) values obtained for the cell lines were much lower in comparison with cisplatin. We demonstrated that the three new Pd(II) complexes are able to induce G2/M phase arrest in AGS and HepG2; in addition, the Pd(II) complexes caused an S phase arrest in Kyse-30 cell line. Our results indicate that newly synthesized Pd(II) complexes may provide a novel class of chemopreventive compounds for anticancer therapy
Association of vitamin D levels and receptor gene polymorphisms with medullary thyroid cancer
Background: Thyroid cancer is the most common endocrine malignancy. Accounting for approximately 1-2% of all cancers. Thyroid cancers have been divided into four main types: papillary, follicular, medullary and anaplastic. The active form of vitamin D (1,25- (OH) 2-vitamin D3) by binding to its receptor, using genomic and non-genomic mechanisms inhibits the proliferative effect of TSH on thyroid cells. Therefore, vitamin D may have a role in regulating of thyroid gland cell proliferation. Many studies have shown anti-cancer effects of vitamin D in cancers. Polymorphisms of Vitamin D receptor can influence the prevalence to various cancers. In the present study, serum level of vitamin D and FokI, BsmI and Tru9I polymorphism of vitamin D receptor was investigated.
Methods: This case-control study was performed in the summer of 2015 in Endocrinology and Metabolism Center of Shahid Beheshti University of Medical Sciences, Tehran, Iran. Forty medullary thyroid cancer patients and 40 healthy controls were investigated. Genomic DNA of subjects was extracted with saturated salt/proteinase K and polymorphisms of vitamin D receptor gene investigated by polymerase chain reaction-sequencing. Serum level of vitamin D evaluated by ELISA technique. The results were analyzed by SPSS, ver. 20 (Chicago, IL, USA) and GraphPad Prism, ver. 5 (GraphPad, Inc., CA, USA) softwares.
Results: Genotypic and allelic abundance of FokI and BsmI polymorphisms between test and control groups have not shown significant different. In Tru9I polymorphism, Tt genotype abundance in test group were 45 percent and in control group were 17.5 percent and t allelic abundance in test group were 25 percent and in control group were 8.7 percent which this different were significant. Average serum level of vitamin D in test group was 23.32 ng/ml and in control group was 18.95 ng/ml which was statistically significant.
Conclusion: Unexpectedly, serum levels of vitamin D in test group were higher than control group. Tru9I polymorphism is significantly correlated to medullary thyroid carcinoma prevalence
