Background & Objectives: Lung cancer due to low chance of survival is the most important and the most common fatal cancer and has the highest mortality rates compared to breast and prostate cancer and other multiple cancers. The purpose of this study is to analyze survival data of patients having lung cancer in the province of West Azerbaijan. Materials & Methods: The information of this study is relevant to 355 patients refered to hospitals exiting in West Azerbaijan province between 1386-93. The situation of the patients was followed up until the end of the Khordad 1393. The data are compromized from Histopathologic and demographic information. For analyzing the data and classifying the patients, the model of decision tree was used. All analysis and synthesis were performed using the software of R. Results: The mean and the median time of survival for 355 patients having lung cancer were estimated 13 and 4.8 months, respectively. The probable of 1-year surviving was about 39% and only 7% of patients had experienced 3-year survival. The model of decision tree of state therapy variables, Eastern Cooperative Oncology Group (ECOG), smoking status, age of diagnosis and tumor stage were identified as important variables. Conclusion: The model of classification tree can identify the important and effective risk factors on the survival of the patients and identifying these factors in the cancer patients can prevent progression of the disease and increase survival time of patients.

Background and purpose: Stress and anxiety as important and common disorders in humane societies can lead to many other diseases. Due to the relatively high side effects of tranquilizers and anti-anxiety chemicals, the tendency to use herbal medicines as a treatment for anxiety disorders is increasing. This study evaluated the effects of alcoholic extract of Papaver rhoeas on anxiety in elevated plus maze, weight and plasma corticosterone levels in rats. Materials and Methods: In this experimental study, 56 adult male rats were used. They were assigned to 7 groups of 8 animals including control group (no treatment), sham 1 (receiving saline), sham 2 (exposure to plus maze) and three experimental groups that received doses of 100, 200 and 400 mg/kg alcoholic extract of Papaver rhoeas via intraperitoneal injections. Elevated plus maze was used to measure anxiety. The number of ties mice were present in the open and closed arms of the maze was calculated and their plasma levels and body weight were measured. The data were analyzed using SPSS-18 via one-way ANOVA and Tukey follow-up tests. Results: The results showed that the alcoholic extract of Papaver rhoeas at the given doses increased the number of entries into the open arms of elevated plus maze. It increased weight gain of animals and reduced plasma corticosterone levels at doses 200 and 400 mg/kg at pConclusion: Probably due to its sedative properties and its morphine materials, Papaver rhoeas extract reduces anxiety levels and corticosterone and increases the weight of the animals under study.

Background and Purpose: The present study was carried out to determine the potential antibacterial agent of ethanolic extract of Hibiscus Sabdariffa against Klebsiella Pneumonia isolation of urinary tract infections. Methods and Materials:The leaf H. Sabdariffa was properly dried and pulverized into a coarse powder as described by Hanafy. Twenty grams of grinded powders from each plant were soaked in 60 ml of ethanol (95 %v/v) plus water, separately for one day with occasionally shaking. After one day of dissolving, materials were filtered through a Whatman no. 1 filter paper .Then the filtrates were evaporated using rotary evaporator. At last, 0.97 g of dried extract was obtained and then stored at40C in an air tight screw-cap tube. Isolation of bacteria : All 12 K. Pneumoniae were isolated from urine culture of hospitalized patients (Amir Al-Momenin Hospital, Zabol, south-eastern Iran), whom suffered from urinary tract infections during the years 2010- 2011. Isolated bacteria were identified by Gram's stain and standard biochemical tests. Sensitive strains to several antibiotics were evaluated by the disk diffusion method with standard Kirby - Bauer. Results: Results showed Klebsiella Pneumoniae isolates resistant to the antibiotics Erythromycin (75%) , Cefixime (3/58%) and Ceftazidime (3/33%). The results showed that the ethanol extract of Hibiscus tea with 10 ml / mg and l5 mg/m density have maximum inhibitory against Klebsiella Pneumonia samples and only one strain of K. Pneumoniae is inhibited in concentration 1/25. Discussion: It seems that H.Sabdariffa extracts could inhibit the growth of all of the mentioned bacteria. We noticed that the bactericidal effect of H.Sabdariffa extract was less than its bacteriostatic effects.

Background & Objectives: Amygdala kindling is accompanied with alteration of the electrophysiological characteristics of pyramidal cells in CA1 area of hippocampus. However, it is not clear that when and in which seizure stage do these changes occur during kindling. In the present study, changes in the electrophysiological properties of hippocampal CA1 pyramidal neurons following partial amygdala kindling in rats were compared to full kindled state. Materials & Methods: Animals were rapidly kindled by 1 ms square waves, 50 Hz, for 3 s. These stimulations were applied to the amygdala 12 times per day at 5 min intervals. Animal received kindling stimulation until achieving stage 2 (partial kindled group) and stage 5 (full kindled group). 24 hours after the last kindling stimulation electrophysiological properties of CA1 pyramidal neurons were assessed by using whole-cell patch clamp technique. Results: Obtained data from amygdala kindling showed that adaptation index, Rheobase, utilization time and the amplitude of afterhyperpolarization potential in partial kindled and full kindled compare to control were significantly decreased and the numbers of action potentials were significantly increased. Conclusion: The present findings showed that in spite of in partial amygdala kindling, the number of stimulations that rats will receive is lower than full kindled animal but it can change neuronal hyperexcitability through alteration of the electrophysiological characteristics.

Purpose: To report different manifestations of recurrent lattice corneal dystrophy (LCD) in two penetrating keratoplasty (PKP) grafts of a patient. Case Report: A 65-year-old man diagnosed with LCD underwent PKP in both eyes which were performed twice in the right eye 18 and 2 years and once in the left eye 16 years before the recent presentation. He complained of decreased visual acuity in both eyes. Best-corrected visual acuity was 2.5 m counting finger in the right eye and 20/100 in the left eye. Follow-up examinations revealed the recurrence of dystrophy characterized by subepithelial and anterior stromal haziness in both grafts and branching stromal lattice figures in the left. Conclusion: Recurrent LCD can have different manifestations in PKP grafts, depending on the follow-up period.

Background & Objectives: Fluoride concentration in drinking water is one of the effective parameters in human health, and the majority of the body's requirement for fluoride is supplied through drinking water. Fluoride in low concentration is essential for human but in high concentration is very hazardous for human health. In the present study, the efficiency of modified-clay and lime-marl as adsorbents was investigated for the elimination of fluoride from aqueous solution. Material & Methods: This experimental study was conducted at the Hamedan University of Medical Sciences in 2014. The effects of several parameters such as pH (4, 7 and 10), the adsorbent dosage (1, 5 and 10 g/L), initial concentration of fluoride (5, 10 and 15 mg/L), contact time (15-120 min) on the removal have been studied. Also, the structural characteristics of both adsorbents were evaluated using X-ray diffraction (XRD) and Fourier transform infrared spectra (FT-IR). Results: According to the results obtained, the removal efficiency of fluoride, at concentration 10 mg/L and the approximate time of 60 min, in the case of clay-modified adsorbent is 95.23% and in the case of lime-marl adsorbent is about 28.71%. Langmuir and Freundlich coefficients were determined in the optimum conditions, and the adsorption isotherm could be described by the Langmuir model(R2=0.9907). Kinetic study showed that the equilibrium time was 60 min. The adsorption kinetics fitted well with the Ho pseudo second-order kinetic model (R2=0.994). Conclusion: According to our finding, it is proposed that the adsorption process of fluoride by clay-modified is very efficient and economics for fluoride removal from aqueous solution.

Background and purpose: cardiac catheterization is one of the most common diagnostic and therapeutic methods of heart disease, Teaching methods such as group training creates the feeling of comfort and make the patients more relax, as well as it changes their psychological and physiological responses. The present study was conducted to determine the effect of group emotional expressions, on stress level of patients awaiting for cardiac catheterization. Materials and Methods: This interventional study (randomized trial) was carried out on 80 patients undergoing coronary angiography for the first time, in Vasee Hospital of Sabzevar in 2014. The samples were selected according to patients available on random days. In the intervention group, emotional expression method was performed. Data were collected via State Trait Anxiety Inventory (STAI), and standard anxiety questionnaire. Data were analyzed by SPSS software using Chi-square, Fisher exact and analysis of covariance. (Significant level=0.05) Results: The average age of participants in this study was about 54.11±10.67 years. Among all patients, 39 participants (48.8%) were male and 41 participants (51.2%) were females. In the intervention group, mean score of STAI decreased significantly in comparision to the control group (p‹0.010). Conclusion: Group expression of emotions affect patient’s anxiety undergoing first time coronary angiography. Therefor it's recommended to use this method befor cardiac catheterization performance.
