Abstract
For monitoring of renal transplant function, serum B2m was evaluated in 23 recipients. According to clinical diagnosis the patients were in four groups: 1) Successful renal transplant the mean concentration of SB2m pretransplantation was 73.1±26.1 mg/L but decreased to nearly normal level (4.43±1.17 mg/L) within 24-48h and then reached to 3.1 mg/L duting 20 days after transplantation. 2) Renal dysfunction (except rejection) the maximum changes of SB2m was 1.1 mg/L/day and no significant changes of SB2m were found between this group and group 1. 3) Accelerated and acute rejection during immunological rejection crisis, SB2m level increased and after response to antirejection therapy decreased. The daily changes of SB2m allowed to diffrentiate renal dysfunction fom rejection in 84% of cases. Moreover according to SB2m fluctuation levels, SB2m had a prognostic pattern for acute rejection due to significant differences between the level of SB2m on the day of clinical diagnosis of rejection and 4 days previously (P<0.025), and also 2 days before rejection (P<0.025), while this pattern was not found for serum creatinin and BUN.

Abstract
Ito cell (Fat Storing Cell=FSC) is one of the cells which forms the liver sinusoidal wall it also forms the connective tissue of the liver. The cell was first identified in 1963 by a scientist named Ito. It will get damaged due to the plasma fat increase which is resulted from a diet of corn oil 10% and fish oil 10% the damage wil be in form of fat storing cell. The FSC morphology may represent the damage to the liver tissue. The biopsy of an infant's liver reveals that, Ito cell has a very small cell body which contains a core in the middle occupying 2/3 of the area of cytoplasm its basal cytoplasm is hollow and very clear. This study indicated that not only the ultrastructure of Ito cell is circular and three dimensional, but also its presence may show the damage to the liver tissue.

Abstract
In our investigation, rabbit hyper-immune serum to V.cholerae ogawa was absorbed with V.cholerae inaba whole-cells and vice versa. Applying ammonium sulphate precipitation method, mono-specific g globulins were purified and concentrated from the absorbed whole serum. These antibodies were fixed on staphylococcus cowan 1 NCTC-8325 whole-cells, using different chemical fixatives. It was observed that maximum fixation of g globulin to protein-A was achieved by 1-propanol 50% at 3 hours, which revealed through single radial immuno-diffusion techniqe. The rectal swab samples were cultured in an enrichment bile-peptons broth. After 5 hours 37°C while agitations, one drop of each sample was mixed with one drop of vibrio-cholerae bivalent mono-specific coagglutination reagent (VBCR). The results were read after 2 to 3 minutes. Finally though statistical analysis sensitivity and specificity of coagglutination test were calculated to be 95.1% and 99.2% respectively, when compared to positive & negative controls and conventional culture methods. Using VBCR, coagglutination test can be therefore considered as a simple, reliable and rapid method to detect V.cholerae O1 in the stool of patients in endemic area and less equipped laboratories

Abstract
Children undergoing general anesthesia for strabismus surgery have a higher incidence of postoperative vomiting than those receiving the same anaesthesia for other types of ambulatory surgical procedures. Droperidol (0/0 75 mg/kg IV) and promethazine (0.05-1.0 mg/kg) were used in 100 children between 2-15 years old. Promethazine which has sedative property, anticholinergic antihistaminic, antiemetic and anti-motion sickness effects is recommended for children 0.05 mg-1.0 mg/kg of body weight IV. After induction of anesthesia and before operation and manipulation of the eye and combined with 0.5 mg/kg IM promethazine after operation. The incidence of vomiting following strabismus surgery might be reduced more than with intravenous droperidol

Abstract
The Behcet disease (BD) is a systemic inflammatory disease of unknown etiology. Evidences suggest that at least some of the clinical aspect of the BD may be due to autoimmune responses, these includes elevated levels of immunoglobulins (Igs) and immune complexes. To clarify the molecular basis of the changes in the level of different classes of Igs in BD, we have detected the amount of IgG, IgM, IgA, IgE and number of B-cells (CD22+) in 68 patients with BD, 28 patients controls (PC) and 30 normal controls (NC). The amount of IgA (P=0.0007), IgM (P<0.000001) and IgE (P=0.005) shows a significant chages in BD to comparied with the NC. But IgG levels don't show any difference. The number of B-cells (CD22+) have not show any changes in BD in comparied to NC and PC. It seems that the elevation of different Igs levels in the serum of patients may be due to unknown polyclonal stimulations then the elevation of Igs caused the CIC formation and complement activation which followed by tissue damages in BD patients.

Abstract
This study is a review of the causes of depression among disabled soldiers (Janbazan) with severity of disability more than 40 percent. In this study, the total population is 1186. This population is classified based on the percentage of severity of the disability (40-49%, 50-69% and >70%). There are respectively in each. Classes 680, 272 and 234 cases. 10 percent of each class (totally 12 persons) were selected randomely. It must to be mentioned that 4 cases was absent because of different reasons. The results of this study showed that the depression is more prevalent among cases with high percentage of disabilities. The result of this research indicated that 56% of the study group are involved in depression, and from them 32.7% are involved in serious depression. Threr is a close correlation between intensity of depression and special factors such as financial, educational and occupational problems.

Abstract
To improve visual disturbance, optic nerve decompression can be performed via transcranial or tran-sphenoidal approaches. Although the surgical exposure in transcranial approach is favourable, yet the optic nerve's presence in the field may make it vulnerable to damage. Of fighty patients with different types of pituitary adenomas, 35 cases with medium-sized (1-3 cm) tumors have been studied in a randomized clinical trial during a three year period, to compare the applicability of these approaches. While short hospital stay with better visual outcome was observed in fifteen trans-sphenoidal cases, in comparison to 20 trans-cranial cases, however the preoperative visual status and underlying disorders were similar in both groups. Decompressing the optic apparatus, trans-sphenoidally, seems beneficial, where there are no contraindications for the procedure in medium-sized pituitary adenomas

Abstract
We studied the effect of the selective alha-2 adrenoceptor blocker idazoxan and precursor serotonin (5-HTP) on anxiety-related behavior in rats. The conflict drinking test, and evaluator plus-maze were used as model. Idazoxan (2 mg/kg) showed an anticonflict effect, having doses dependently increased the number of punished lickes. 5-HTP showed that anxiolytic-like effect in both models. This drug reversed action and produced anxiogenic-like effect at high doses. In contrast, arecholine which is a cholinergic muscarinic agonist drug, produced anxiogenic-like behavior. At 2 mg/kg increased number of entrance (OE) and using time (OT) in open arms in montgomery's test. Anxiolytic-like effect of this drug was less than of chlordizepoxide. These results showed that increase release of noradrenaline in synaptic nerve terminals of neurons produced anxiety-related behavior. While high release of serotonin in this area reduced behaviors disorder in rats.

Abstract
Amount of environmental lead pollution is increased with progression of industry. This pollution is able to damage the living beings in many ways. Blood and Immune systems are more sensitive to toxic effects of lead. 30 female and 6 male rats from Sprague dawley race are chosen by simple random sampling. After copulation and vaginal plug observation, expectant rats are calssified in test and control groups. Since the first day of pregnancy, test group is given a drink containing lead acetate 0.13% in distilled water and control group is given distilled water. After delivery, for ultrastrectural studies, spleen specimens of newborn rats are fixed in glutaraldehyde solution 2% and after processing are studied by T.E.M. Sinusoidal endothelial cell show: morphological changes in mitochondria, appearance of primary & secondary lysosomes and multivesicular bodies and swelling in ER. It seems that these changes are caused by interaction of lead with enzymathic functions or lead accumulation in these cellular organels.

Abstract
Carpal tunnel syndrome (CTS) is considered by researchers because of its high prevalence, and several studies have been done to find the causes and factors which increase the chance for the syndrome. These studies have shown relationships between this syndrome with some physical parameters like wrist dimensions, weight and systemic conditions. There is no investigation on risk factors in CTS in our country. So the main goal of this research is to find and introduce predisposing factors for carpal tunnel syndrome. Methods: Seventy patients and 33 controls 22 to 70 years old were studied. Standard methods for median and ulnar nerve studies were used and questionnaires included physical measurements, history of diseases and personal information were completed for each person. Results: Patients had higher wrist ratio (mean difference, 0.0267, P<0.001), weight (mean difference: 6.098, P<0.001) and body mass index (mean difference: 3.376, P<0.001). Regression analysis showed strong positive relation between wrist ratio and median latencies. The strongest correlation was found between wrist ratio and median minus ulnar distal sensory latencies (Y2=0.4014, P<0.0001). No relation was found between weight and body mass index with median latencies. Seventy-nine percent of patients and 48.5% of controls had wrist ratio of 0.7 or greater (P<0.05). Seventy-two percent of patients with repetetive hand activities and 78% with associated conditions had wrist ratio of 0.7 or greater. Seventy-six percent had wrist ratio less than 0.7. No relationship was found between obesity, diabetes, thyroid disorders, rheumatoid arthritis, taking oral contraceptive, hysterectomy, oophorectomy, menopause and repetetive hand activities with involvement of carpal tunnel syndrome. Discussion: Wrist dimensions seem to be an important predictor for carpal tunnel syndrome also in patients with associated conditions. If individuals with squarer wrists are involved in special conditions, they may show symptoms of the syndrom. Carpal tunnel syndrome is caused by many factors but wrist dimensions seem to be a predisposing factor and provides an explanation for bilateral involvement or familial occurrence of it.

Abstract
This inverstigation is a quasi-experimental study comparing the effects of two methods of health education on student's knowledge and attitudes about AIDS. The target population consisted of 218 male undergraduates studying in Payame Noor University in Saghez, Iran. A random sample of 106 students was selected using sample random sampling method. The students were randomly divided into two experimental groups. One group was educated about AIDS using a direct method of health education and indirect method was used for the other group. Using pretest/posttest method of data collection, analysis of the data showed a significant difference between each group's knowledge and attitudes before and after the educational programs. Comparison of the two educational methods showed no significant difference on student's knowledge about AIDS. However, method one (using a direct method of health education) was significantly more effective in changing student's attitudes towards AIDS than method 2 (using an indirect method of health education).

Abstract
325 female students of Zahedan at the average age of 16.2 years old (16-22) were randomly selected to study the prevalence of iron deficiency anemia. Hb, hematocrit, MCV, MCHC, iron, TIBC and ferritin were measured. Results showed that in the population studied 3.4%, 27.7%, 4.3%, 11.7%, 25.5%, 11.4% had their Hb, MCV, serum iron, tranferrin saturation, ferritin respectively below the WHO standards. The correlation coefficient between Hb, MCV and hematocrit, serum iron was r=0.54, P<0.00001, r=0.38, P<0.00001 respectively. Also the correlation coefficient between transferring saturation, serum iron and ferrin was r=0.94, P<0.00001, r=0.31, P<0.00001 respectively. Our study shows that hematological and biochemical markers of iron status of the young Zahedan girls at puberty are lower than WHO standards and these girls might be at risk of iron deficiency anemia.

Abstract
In this quasi-experimental study, we have evaluated the effects of an educational program on the level of knowledge, attitude and practice methods of experimental assistant dentists in Shiraz, regarding AIDS and HIV transmission. These variables were assessed before and after an educational program, by a questionnaire and a checklist. The educational program consisted of lectures and group discussions, held in 4 sessions during one month. The second assessments of knowledge, attitude, and of practice methods were performed six weeks and three months after the completion of the educational program, respectively. The scores were significantly different before and after the educational program, which can therefore be considered effective in improving knowledge, attitude and practice methods in the cases under study.

Abstract
This survey, evaluated the level of awareness and knowledge among the medical staff about conditions and methods of performing cardiopulmonary ressucitation. The study sampling comprised 497 subjects including 208 residents and 262 interns of ten university hospitals in Tehran. In regard to the basic principles, this has been 43.54% (SD = 13.36%), in drug and fluid therapy 31.22% (GD = 13.22%), in electroshock 43.6% (SD=21.12%), in appropriate approach to the problem 34.73% (SD=13.42%) and in complications of CPR 17.7% (SD = 15.25%). Considering the results of the project, the medical staff have insufficient knowledge of CPR md it does not improve significantly during internship and residency period. Therefore, there is a great necessity for the medical students to attend basic and advanced CPR courses during their study

Abstract
To study the lead effect, we selected 14 females rats in which we had observed vaginal plague after mating, and divided them into a group of 8 female rats as the case group and 6 females as the control group. As drinking water the case group was given 0.13% lead acetate solution and the control group pure distilled water. Immediately after parturition the pups were killed and their livers removed. A small part of the liver was fixed in glutaraldehyde and osmium tetroxide in order to be studied with transmission electron microsope. The fixated parts were dehydrated and embed in Epon 812. using ultramicrotomoe, we prepared semithin seclions of the tissues, stained them with toludine blue, and studied them under light microscope. Further more we prepared thin sections of the tissue to be placed on grids coated with formvar. These sections were stained by uranyl acelate and lead citrate. Electron microscopic study was performed on them. Results: T.E.M. study showed the swelling and blebbing of nuclear envelop and endoplasmic reticulum and mithochondria of hepatocytes.

Abstract
The effect of some anthropometric factors and loading on paravertebral muscles was tested in this study. Thirty two healthy men with mean age of 25.25 years participated in this study. They didn't have history of low back pain since 12 months ago. The effect of weight, height, upper limb length, abdominal & chest circumference and upper body height and other factors e.g. body mass and functional capacity indexes on maximum isometric torque of paravertebral muscles and spinal range of motion in all planes of movement and effect of loading with 0, 5, 10, 15 kg loads on paravertebral factors e.g. dynamic torque, velocity, work, power, and slope of torque was examined with a dynamometer named ISOSTATION B-200. Correlation, analysis of variance and t-test was used in SPSS program. Results show that maximum isometric torque and functional capacity index increased with increasing weight abdominal and chest circumference and body mass index (P<0.05). Height, upper body height and upper limb length don't have effects on this factors, and anthropometric factors don't have effects on range of motion. Maximum dynamic torque, maximum velocity, work and power were significantly increased and time of movement & slope of torque were significantly decreased while load increased (P<0.05). This study showed that load-velocity relationship in limb muscles can not help the paravertebral muscles studies because paravertebral muscles histologically differ from limb muscles.
