Abstract
Introduction: The off response of baroreflex is mostly ignored by recent studies. In the present study we aimed at assessing this during rest, and isometric and dynamic exercise.
Materials and Methods: 12 young male subjects volunteered the study. Using an Eckberg neck suction device each subject received a brief (10 sec). about of sustained stimulus with -50 mm Hg pressure in the neck chamber. The workload incorporated was 100w for dynamic and 50% of maximal effort for isometric exercise. Electrocardiogram was recorded on line R-R intervals were assessed beat and responsed cardiac response. This was significant at all three states.
Results: on the average, the peak off-response tachycardia occurred earlier (3rd sec). in exercise tests as compared with that of rest (5th sec). the intensity of tachycardia was more prominent at rest, isometric exercise, and dynamic exercise, respectively and the difference between rest and dynamic exercise gained significance (p<0.01).
Conclusion: The attenuation of so called post vagal tachycardia during exercise is in accordance with the assumed reduction of vagal tone during exercise.

Abstract
Introduction: At present, bone graft is unavoidable. In fact although among the all probable bone grafts, the autograft is the best choice, but because of some situations like two coincidence surgery upon one individual, size limitation of autografts (its impossible to get a big piece of graft from patient) increasing the bloodshed contingency, infection etc, made specialist to think about the possible substitution the allograft.
Materials and Methods: Seventeen Newzealandian rabbits were divided into four groups. The graft generator group consisted of one rabbit which was genetically different from other groups. The sham group composed of three rabbits which round autografts about 4 mm in diameter from their tibia were exchanged between rights and left tibias. These grafts were not deantigenized and a 4 mm vacant hole was created to see if it will repair spontaneously within three months. The control group consisted of three rabbits received a round 4 mm tibial autografts which double deantigenization process were done over them. The test group composed of 10 rabbits, received corticocancellous (intramembranous) allografts in left tibia and corticocancellous (endocondral). Allograft in right tibia all grafts were bearing the double deantigenization process.
Results: The rate of prosperity for CCl grafts was 80% and for CCE grafts was 60%.In sham group, healing process was extremely fast (in eight weeks).
In control group, healing process was done slower until six weeks but after 12 weeks it was compensated. The vacant holes were not repaired even after three months. Statistically, there was a meaningless difference between the rates of prosperity in both groups of grafts.
Conclusion: According to statistical assays, although the prosperous numbers of CCl were more than CCE grafts but this difference was meaningless. In the basis of histological assessments if the velocity of healing process is important, the CCI grafts are recommended

Abstract
Background: Allah descended the holy Quran to guide the human and for instructing him the principles of life. The holy Quran always guides the human in the best of ways. Accordingly, the aim of this study was to explore the manifestation of Quran reading in the life of faculty members, students, and clerks’ at Arak University of Medical Sciences (AUMS). Materials and Methods: This qualitative study was done through content analysis method, and the data were collected through interviews. The study was initiated with purposive sampling and continued by theoretical sampling 30 individuals were interviewed over a 2 month period at AUMS. The data were analyzed based on the content analysis method. Continuous-comparative analysis was utilized for data analysis. Results: Data analysis showed the manifestation of miracles in life, achieving internal peace, having humanistic communication, decision making based on Quran instructions, being patient and tolerant, behaving based on Quran instructions, and saving as secondary codes of the effect of Quran reading on participants’ life, and “the effect of holly Quran on the whole dimensions of life” as the main code or theme. Conclusion: In this qualitative study, using triangulation sources, the effects of Quran reading on the faculty members, students, and clerks’ life at AUMS were identified more profoundly than the quantitative methods. On the other hand, the effect of Quran reading on all dimensions of the participants’ life, as the theme of this study, is a very important finding which is completely in accordance with Allah’s words in Quran. Therefore, in order to achieve more divine benefits from Quran, reading the holy Quran is recommended to academians and all people, in general, so as to compete for using Quran more.
