This correlation descriptive study is intended to determine the locus of control and its relationship with the educational progress of the students of nursing at Sabzevar School of Medical Sciences in sabzevar, Iran. 97 sophomores with known averages were selected and requested to fill out the questionnaire. Causal Dimension Scale (CDS) was used for data collection. Pearson correlation coefficient, t-test and chi-square were utilized for data analysis. 12.4 % (12 students) were male and the rest were female. The results indicated no significant relationship between the scores of locus of control and the students' averages. Also, no difference was found to exist between the two sexes as for the type of the locus of control.    

Diabetic gasteroparalysis is a kind of motor electromechanical disorder in which gaster and other portion of GI system is motionless. In this research, we examined effects of morphine addiction on diabetic gastroparalysis. We divided the 30 female N-MARI rats in 4 groups. In normal groups, all rats received salin (volume / kg). In the diabetic group, all rats received STZ (45 mg/kg); in normal addict group, rats received morphine 30-50 mg/kg for four sequential days and twice a day. In the fourth group, rats received first STZ (45mg/kg)Sc and then morphine (30-50mg/kg Sc). For addiction test, withdrawal syndrome was evaluated. Gastroparalysis is studied by macroscopical and microscopical slice. Slices stained by H&E and trichrom mason. We found that gastric morphology in diabetic rats is larger than normal rats; in addition, gastric morphology in diabetic rats is larger than normal rats; fundus in diabetic rats was of less folding. The thickness of extrnal muscular layer in diabetic rats is thinner but its histological structure is not changed; pylor sphincter in diabetic rats was hyperthrophized. In addict diabetic rats, only epithelial layer grew and folded and gaster volume in addict diabetic rats was less increased (P<0.05). These results indicated that addiction improved the gasteroparalysis in diabetic rats.    

Helicobacter pylori, found in the mucus of epithelial cells of the stomach, can cause mucous changes, cell lysis and inflammation. It contains such virulent factors as spiral form, motility, Hp adhesive molecules, urease enzyme (UE) and a few others. UE is of paramount importance due to its hyperactivity. This study will focus on the role of UE in causing cell lysis in different samples. 80 positive samples, out of 100 samples, were examined and all were observed to contain oxidase, catalase and UE. Curved spiral shapes were observed in direct and pathological slides which were studied. The direct effect of HP Suspension on cell culture was observed in 50 samples by adding 20 m.molar of urea. Adding bacterium suspension to 20 m.molar of urea caused the color of the culture to change into dark purple, which indicated the production of a considerable amount of ammonia (HH3). Also, intercell vacuol (ICV) formation was observed. However, no such formation was observed without urea. The effects of different concentrations of ammonia (7 , 21 ,32 and 40 m.malar) on the formation of ICV were studied and the results indicated that ICV was not observed with NHc concentrations of less than 7 m.molar . In densities of 8 m.malar NH3, cytopathic effects were gradually observed in the form of vacuols and increase in the number of ICV. In 21 m.malar NH3, a few cells were damaged; however, in densities of 32 and 40 m.molar NH3 , complete cell lysis appeared.        

Fasting during Ramadan can be good for one's health and personal development. Ramdan fasting has spiritual, physical, psychological and social benefits. The body has regulatory mechanisms that are activated during fasting. There is efficient utilization of the body fat. A diet that is less than a normal amount of food intake but balanced is sufficient to keep a person healthy and active during this month. The effect of Ramadan fasting on some of the blood parameters such as serum glucose, uric acid, lipids, and proteins, were investigated on male students of nursing. 29 normal and healthy students volunteered to participate in the study. The subjects fasted about 11 hours a day for 28 days. Their blood samples were obtained from the volunteers on the first and 28th days of the period. Paired t-test was used for data analysis. However, serum uric acid, cholestrol, LDL-cholestrol, proteins and albumin levels reduced significantly. The results of the study indicated that Ramadan fasting is perfectly safe for adults with normal health.      

Sellar and parascllar regions consist of pituitary gland, hypotary gland, hypothalamus , optic nerve and chiasma, internal carotid artery and branches, cavernous sinus and medial portion of temporal labe . In this cross-sectional study, we collected 58 cases of sellar and parasellar tumors in Kerman from 1997 to 2001. 48% of the cases were male and 52% were female. Their mean age was 34.4± 19.3. The most common tumors were pituitary adenoma (41.4%), meningioma (24.2%), craniopharyngioma (20.7%) and astrocytoma (6.9%). Epidermoid tumor and chordoma (3.2%) were not as frequent (3.2%. Headache was the most common symptom in 82.8% cases. No significant difference was found between the two sexes as for the prevalence of the tumors . But significant statistical difference was found in their mean ages. The findings suggested that pituitary adenoma was the most frequent tumor in the region like other studies      

This study is intended to determine whether intrauterine insemination (IUI) after ovarian stimulation with clomiphen citrate (cc) gives a better pregnancy rate than natural intercourse in couples with subfertility because of subnormal semen. This study is a prospective randomized controlled trial. Couples with subnormal semen as only identifiable cause of subfertility. In control cycles, the couples had natural intercourse. In IUI cycles, IUI was performed after ovarian stimulation with cc and human chorionic gonadotropin. The clinical pregnancy rates and complications of IUI cycles and control cycles were compared. The results indicated that there were four clinical pregnancies in the 32 IUI cycles, whereas there was no clinical pregnancy in the 32 control cycles. The clinical pregnancy rate in IUI cycles (12.5% per cycle) was significantly higher than that in control cycles (0%).  None of the patients developed ovarian hyperstimulation syndrome in IUI cycles. Therefore, intrauterine insemination after ovarian stimulation with cc is useful in treatment of subfertile couples with subnormal semen.      

The determination of in-hospital outcome in patients with Acute Myocardial infarction (AMI) is important for choosing the therapeutic method, management, kind of care and duration of hospitalization. Electrocardiogram is a cheap, simple and available method for AMI diagnosis and it will be more valuable if its findings can help to determine in-hospital prognosis and identification of high risk patients. In this study, one hundred patients with AMI were randomly chosen; fifty of them died in hospital (main group) and he other fifty were discharged alive (control group). Their demographic data and electrocardiogram findings at the time of admission were extracted. This investigation showed that more patients of the main group, in comparison with the control group, had no sinus rhythm; their heart Rate> 100 beats/min, P wave amplitude> 1 m.v, QRS duration> 0.12 s. In the main group, the prevalence of ST elevation in anterior and aVR leads was higher than control group. The proportion of patients who had one kind of cardiac block, was higher than other main group. Patients in the main group had higher sum of ST elevation than those of the control group. According to our current study, in patients with AMI , some electrocardiogram findings including Rhythm, Heart Rate , P wave amplitude, QRS duration, Location of ST elevation, high sum of ST elevation and Variety of cardiac blocks are important for determination of in-hospital prognosis.      

Since pain is the main debilitating cause of knee ostheoarthritis, application of local analgesics have been the center of attention to avoid their systemic complications especially since ultrasound application can enhance their local absorption. This study was conducted to determine the effect of pyroxicam gel (which is very common in our country) with ultrasound on pain soothing in patients with knee ostheoarthritis . This double blind clinical trial was experimentally conducted on 90 affected knees taking inclusion - exclusion criteria into consideration. Patients were randomly assigned into experimental and control groups, receiving "pyroxicam + ultrasound" and "ultrasound gel + ultrasound" respectively, for five successive days. Before and after treatment, Knee Pain Scale, Visual Analog Scale and Investigator Total Assessment were checked. The difference of these three indicators before and after the treatment were statistically analyzed using t-test , paired t-test and Mann Withney test. Findings revealed that all three indicators suggested a decrease in pain, which was significant in "Pyroxicam + ultrasound" group (P>0.000l) . The two groups were homogeneous as for their sex, age and BMI . It was finally concluded that "pyroxicam with ultrasound" is more effective than ultrasound alone, and hence it is recommended for routine physiotherapy.      

Suggestion is a communicative phenomenon in which a person unconsciously changes his/her idea, judgment, feedback and even behavioral patterns under the influence of some other person. In this experimental study, negative and positive attitudes towards an action facing the subjects. This experimental study investigates the effects of suggestion on psychomotor practice with consideration of IQ. 60 pre-university students in Jiroft were randomly selected in 1378 -79  The plan was to investigate the groups with positive suggestion, without suggestion and negative suggestion; also with an experimental plan of simple, difficult and general psychomotor practice. Results revealed that positive suggestion affects on simple, difficult and general psychomotor practice but mean scores of the negative-suggestion group and no-suggestion group difficult practice and mean score of the positive-suggestion group and no-suggestion group in all three fields (simple, difficult and general) did not show any significant differences.      

This research has been done with the intention of determining the effect of sensory stimulation program on the level of consciousness on the coma in head injury patients. This quasi-experimental research has been done on 76 patients suffering from coma in head injury referring to Emdady Medical Center ICD in Mashhad, Iran, Sampling method was based on purpose. Subjects were randomly put into two groups: control and experimental, each containing 38 subjects studied for 14 days. First demographical information of patients were recorded; 24 hours after admission to ICD, Glasgow coma score was measured and sensory stimulation program was done every hour for 6 hours. G.C.S. score was again measured. For the next 6 hours, the method of work was replicated. Results indicated that there were no statistically significant differences between the average levels of consciousness but there is a meaningful difference between the average lengths of hospital staying. Therefore, sensory simulation program may be useful in coma recovery    

Thrombophelebitis of cavernous sinus is presented with high fever, edema and erythema of the lids, bilateral proptosis, frequent vomiting, headache and other signs of increased intracranial pressure. Sometimes convulsion or coma is also seen. To MRI or brain CT Scan are diagnostic. In this article, we have reported a typical case of this disease in a 14-month-old infant.      

Incisional endometriosis may be more uncommon than previously recognized. From October 1998 to Agust 2000, three patients with the diagnosis of cesarean section scar endometrioma were studied in Zynab University Hospital. They presented with a painful slow-growing lump at the lateral edge of their incision. All patients were treated with surgical excision and pathological diagnosis was incisional endometriosis.
