Background and Aim: Airways responses during extubation can lead to coughing, laryngospasm and hypertension. The aim of this study was to compare the effects of intratracheal and intravenous lidocaine on airway responses and cardiovascular effects during extubation .
Materials and Methods: This clinical trail was preformed on sixty 15-60 year old patients undergoing general or gynecological surgery, who were class I and II based on the classification of the American Society of Anesthesiology. Three minutes before the end of surgery and at the same time stopping the anesthetic gases, lidocaine was administered 1.5mg/kg intravenous or intratracheal. The number of bucking and coughs till extubation, number of cough till 30 minuets after extubation, the interval between stopping the anesthetic gases and extubation and also heart rate and blood pressures were recorded. Data were analyzed by SPSS version 16 using chi-square and t-tests at the significant level of P<0.05.
Results: The mean times for extubation in intravenous and intratracheal lidocaine group were 11.3±3.6 and 11.7±4 minuets, respectively (P=0.71). There were no significant differences in numbers of bucking (P=0.19) and numbers of cough (P=0.97) between the two groups. No significant differences were observed in cardiovascular variables between the two groups .
Conclusion: The effects of intravenous or intratracheal administration of lidocaine on the rate of bucking, cough and the time for extubation at the end of general anesthesia were similar .

Background and Aim: Blood donation causes changes in physical and physiological characteristics. The purpose of this study was to investigate the effects of blood donation on the exercise performance and some of hematologic parameters in physically active and non-active women.
Materials and Methods: In this experimental study, 14 active women with history of physical exercises more than 6 months and 16 non-active women, ranging form 20 to 30 years old, were participated voluntarily. Hemoglobin, hematocrit, serum iron and exercise performance parameters (including maximal oxygen uptake and anaerobic power) were measured 24 hours before, 2 days and 4 weeks after blood donation. Data were analyzed by means of SPSS (version 16) at the significant level of P<0.05.
Results: Serum hematocrit and hemoglobin in both groups were significantly decreased 2 days and 4 weeks after blood donation (P<0.001 vs the day before donation) and were significantly increased 4 weeks comparing 2 days after blood donation (P<0.001). Maximal oxygen uptake was increased significantly only in non-active women, 4 weeks after donation comparing with 2 day after and the day before donation (P<0.001 for both). Peak anaerobic power was increased significantly only in active women, 4 weeks after compared to the day before donation (P=0.03).
Conclusion: Although compensation mechanisms for hematocrit and hemoglobin are similar in both active and non-active donors, they are different for maximal oxygen uptake and anaerobic peak power and may response independent of hematocrit and hemoglobin levels.

Background and Aim: Gestational trophoblastic disease (GTD) is one of complications of pregnancy and has different subtypes (complete mole, partial mole and choriocarcinoma). Macrophage derived factor or CCL22 is a member of chemokines that produced by macrophages, dendritic cells and tumors cells. It has an important role in the recruitment of T regulatory cells and T helper2 lymphocytes to the site of tumor. This chemokine has several polymorphisms which the most important is at position 16C/A. This study was aimed to evaluate the polymorphism of this gene and its relationship with GTD.
Materials and Methods: In this case-control study, the peripheral blood of 110 patients with GTD and 120 healthy pregnant women were used for DNA extraction. The polymorphism of the CCL22 gene was investigated with Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) method and analyzed by means of Epi Info 2000 and SPSS (version 11.5) at the significant level of P<0.05.
Results: No significant difference was observed in the polymorphism of CCL22 (including genotypes CC, CA and AA) and the frequency of its alleles between the case and control groups. Moreover, there was not a significant association between CCL22 polymorphism and subtypes of GTD.
Conclusion: It seems that genetic alteration of CCL22 is not associated with GTD,therefor, investigation of other chemokines gene polymorphisms is suggested in future studies.
