Abstract
Abstract Background and objectives: A major problem for labs. esp. medico legal centers is drug test false positive and negative results. Using carbon paper, sodium bicarbonate or oral contraceptive pills (OCP) are common among addict people to make the results negative. Therefore, we decided to evaluate the effect of carbon paper, sodium bicarbonate or OCP on morphine urine test. Material and Methods: We performed this pre-experimental study on the urine samples of all people referred to narcotic drug laboratory of Markazi province during May of 2005. Of 2110 urine samples, the Morphine Rapid Test of 208 samples was positive. Then by means of TLC method, we confirmed the presence of morphine metabolites in 150 urine samples. After that, we divided these samples into three equal groups for adding carbon paper, sodium bicarbonate or OCP. Results: The results show that in carbon paper group, 41 cases are positive and nine cases unclear. In sodium bicarbonate group, 45 samples are positive and 5 cases unclear. In estrogen conjugate group, all 50 samples are positive. Conclusion: According to this study, adding carbon paper, sodium bicarbonate or oral contraceptive pills cannot make negative the Morphine Rapid Test result. Key words: Morphine Rapid Test, Carbon paper, Sodium bicarbonate, Oral contraceptive pill.

Abstract
ABSTRACT
Background and Objectives: Previous studies have shown that morphine dependence leads to myocardial dysfunction. In addition, apelin plays a protective role in cardiac function. The purpose of this study was to evaluate effects of morphine dependence and three models of exercise training on serum apelin level of dependent and healthy rats.
Methods: Ten healthy and 40 morphine-dependent rats were used in this study. The morphine-dependent rats were divided into four equal groups of control addicts, endurance training, strength training and concurrent training. The training exercises were carried out for eight weeks, five days a week. Serum apelin level was measured by ELISA, 72 hours after the last training session.
Results: Statistical analysis demonstrated that apelin level increased significantly in morphine-dependent rats compared to healthy controls. On the other hand, endurance and concurrent training significantly increased serum apelin level in morphine-dependent rats compared to control addicts, but strength training had not effect on serum apelin level in morphine-dependent rats.
Conclusion: Endurance and concurrent training may have cardioprotective effects on morphine-dependent rats by increasing serum apelin levels. Therefore, such training activities could be recommended to morphine-dependent patients to prevent cardiac disorders.
