Vaccination is one of the best methods of prevention against hepatitis B virus. With respect to various vaccines against this virus and based on the differences of selected factors of immunogenicity, various studies on different groups in different locations is necessary. In present research, therefore the titer amount value of antibody against surface antigen of hepatitis B virus (anti-HBs) was determined and its relation with different factors among medical staff was investigated. This study is descriptive observational, retrospective which is conducted using questionnaire and serology tests. 146 persons of medical staff of Shahid Madani Hospital of Tabriz, Iran were the population. The sample size was selected based on the high risk group. Anti-HBs value was measured based on ELISA method. Out of 146 subjects, 32 persons (24%) had no protective titers (anti-HBs<10 MIU/ML), 38 persons (25.3%) had relative protective titers (10≤anti-HBs≤100 MIU/ML), and 76 persons (50.7%) had complete protective titers (anti-HBs>10 MIU/ML). It was indicated that there was a significant relation between antibody titer and age, smoking, and the injection of full dose of vaccine (p<0.05). However, there was no statistical significant relation between level of safety and age, have a contact with patient, and the time elapsed since the last vaccination (p>0.05). Since the medical staff is in the high risk group, full training and vaccination is recommended and their anti-HBs should be analyzed annually and if necessary, revaccination in older ones should be done.

Staphylococcus aureus (S aureus) is one of the important agents of many infections in hospitals and society. Increasing S aureus resistance to antibacterial drugs is one of the major health concerns, therefore studying antibiotic resistance of S aureus is very important and it has a main role in preventing creation of resistant strains. This investigation was a retrospective study and it was done by studying of 513 hospitalized heart disease patient's blood culture records in Tabriz Shahid Madani Hospital during a one-year period (2010). Statistical analysis of data has performed by Microsoft Office Excel software. Microorganisms in 71 cases (%14) of blood cultures grew. Eighteen point (three percent) of positive cultures were related to S aureus. Four cases (%31) of S aureus positive patients were females whereas 9 cases (%69) were males and the age average of patients was over than 40 years. The most of resistant cases (%31) were related to methicillin and ceftriaxon. This study showed that care and control must be performed on these bacteria together with avoiding unnecessary prescription of antibiotics because this affair can create and increase drug resistant strains.
