STOREY Recently PCR is being used more frequently as a diagnostic method to detect M. pneumoniae. We used primer pairs reported by Van Kuppeveld,13 Leng,5 Lunerberg,7 an Bernet' targeting 16s rRNA, PI protein, tuf genes. and a short DNA equence (MP5) to evaluate the sensitivity among different PCRs. Reoptimization experiments showed that tuf PCR had the highest sensitivity amongst these four PCRs, detecting 10 organisms. Detection limit for the rest of the PCRs was 100 copies of DNA. This study confirmed that 92° would be the best dissociation temperature rather than higher temperatures that are still being used frequently in other studies. Be ides. accurate optimizing of the annealing temperature and extension time had important roles on the sensitivity as well as using milli-Q distilled water rather than double distilled water. Experiments done on MP5 PCR proved that the non- specific products mentioned in previous studie 2 were not eliminated by increasing the annealing temperature, although they disappeared on gel electrophoresis after careful optimization of extension time. 1999 5 01 75 79 http://mjiri.iums.ac.ir/article-1-976-en.pdf

Two recombinant plasmids were constructed. One of them contained the coding sequences for the major polypeptide of surface antigen. Another construct carried the major polypeptide with the pre-S2 antigenic determinant. These vectors were transferred into the yeast. Only pDFl which contained the HBsAg gene was expressed. Some peculiar features of recombinant plasmid construction and expression of the HBsAg gene are discussed HBV surface antigen recombinant plasmids Saccharomyces cerevisiae exoression vector. 1999 5 01 67 73 http://mjiri.iums.ac.ir/article-1-975-en.pdf

SILVER Invasive aspergillosis (1 is a life-threatening condition in immunocompromised patients. An early diagnosis is of great importance because early treatment may resolve this potentially fatal infection. Recently, the polymerase chain reaction (PCR) has been used successfully in detecting specific DNA of several pathogen. In this study, nested PCR was used to detect DNA specific for A!.pergiflus species isolated from bronchoalveolar lavage (BAL) fluid from patients with TA. In single PCR using the outer primers a specific 384-bp fragment was amplified. Similarly, y nested PCR with inner primers, a 357-bp fragment was amplified with DNA from Aspergillus fumigatus but not from the other microorganisms. The Southern blot hybridizations confirm the specificity of the PCR procedure for A. fumigatus using the cloned 374-bp PCR product probe. In conclusion, the nested PCR method appears to be quite rapid and specific. 1999 5 01 61 66 http://mjiri.iums.ac.ir/article-1-974-en.pdf

Then this sequence was recloned into the pTrc 99A and pET23a expression vectors to give the pJasmids pTRCLTB and pETLTB, respectively. After induction, the former plasmid provides for the production of rL T-B in a yield of up to 15 mg per liter of bacterial culture. The recombinant protein was shown to be structurally and immunologically identical with the native L TB. High titer antibodies capable of neutralizing the native toxin were raised in mice by oral administration of the rL T-B. Hence the constructed plasmids provide the basis for an oral ETEC vaccine, as well as for genetic fusion of foreign antigens with the aim of developing polyvalent vaccines. ETEC. Recombinant L T -B.

KHOSHBATEN WR FERRELL WJ ANGERSON H NAJAFIPOUR Experiments were carried out on anesthetized adult New Zealand rabbits. Acute joint inflammation was achieved by intra-articular injection of 2% carrageenan. Radiolabelled microspheres were used to measure the effect of acute inflammation on blood flow in the knee joint and establish whether neural influences on blood vessel caliber were affected. Surgical exposure of the posterior joint "capsule" increased blood flow in the control knee, but subsequent section of the posterior articular nerve (PAN) supplying the knee produced no further increase. In the inflamed knee, blood flow declined progressively with ea<.:h procedure. Electrical stimulation of PAN reduced blood flow in the posterior region of both knees, with somewhat less effects in the inflamed knee. Knee joint. Blood flow Microspheres.

The test group received US treatment at 0.5 W /cm2• I MHz, 2 msec on-8 msec off for 10 min/day, from the day after surgery until complete fusion was observed. Radiological studies indicated that mean healing duration and rate of healing was significantly more in the test group than in controls. Histological evaluation showed the presence of ossified callus at week 3 in the test group. but in controls fibrous callus was still seen at week 5 after surgery. Bone mineral analyses by stereoelectron microscope showed that the mineral component of the treated bone revert to normal, similar to the composition of intact bone. and sooner than that of the control. However, our results revealed no deleterious effects of US on treated and untreated ipsilateral and contralateral bones during the experiment or one month after complete fusion of the bones, at which time US was terminated Ultrasound Healing.

The downstream process of purification generally causes depolymerization of Vi-CPS to a nonimmunogenic low molecular weight form. In the present study, a standard strain of Sal. typhi Ty6s was grown under submerge cultural conditions in a pilot-plant scale of 90 Liter fermentor. At the late exponential growth phase, crude polysaccharide wa obtained from fermentation broth by detergent-phenol extraction method and purified by ultracentrifuge differentiation technique. Analytical data reveals that by optimization of fermentation parameters, not only was the yield of production increased from 1.6 mg/L to 4.9 mg/L, but also the polysaccharide retained its native molecular stability and immunogenicity. Therefore, purified Vi-CPS can be regarded as a reliable immunogen to control typhoid fever in man. Salmonella typhi.

A case series study was performed to obtain information about clinical manifestations, age of presentation and diagnosis of CD. For this purpose, hospital records of patients who were admitted to the gastrointestinal ward in the Children's Medical Center from 1986 to 1996 with suspected diagnosis of CD and discharged with such a diagnosis were reviewed. Thirty-five patients (17 male, 18 female) with diagnostic criteria for CD were selected and followed, The average age of onset was 3.07 years but mean age of diagnosis (the first small intestinal biopsy) was 7.7 years. The most common symptom was chronic diarrhea. The interval between initial symptoms and diagnosis was surprisingly long. During this period these subjects had multiple medical visits at different hospitals. With recognition of this treatable disorder and by available diagnostic procedures and obtaining small intestinal biopsy specimens, we can reduce the mentioned interval and diagnose this entity earlier in Iranian children.

Nine elementary schools were randomly selected and 476 pupHs aged seven and nine years and 471 parents were studied. Most parents (90.1 %) believed that their children take risks when they play outside after school anyway. The top three risky activities were climbing walls (25.0%), climbing trees (14.8%) and riding carelessly (14.1 %). Overall, boys were more likely to take risks than girls (47.4% vs. 33.6%, p<O.O I). Although more needs to be learned about children's after-school risk-taking behaviours, it is clear that the pattern of risk-taking behaviour for younger children is different from that of older ones. Boys were more likely to take risks and are at greater risk of being involved in an accidental injury when they play outside after school than girls. Because many children do take risks after school, a broad and balanced approach combining educational and environmental componen ts is essential to prevent after-school childhood accidents.

The mean age of the patients was 11 years. Fever was seen in 85.5%, arthralgia in 95.2%, arthritis in 81.7%, carditis in 82.5%, chorea in 3.8%, and subcutaneous nodules in 0.9% of patients. Mitral regurgitation was the most frequent valvar involvement (79.6%). Sixteen patients (15.4%) had severe carditis. The ESR level was ≥20 Wintrobe units in 98.0%, the CRP was elevated in 83.0%, and the ASO titer was ~400 Todd units in 91.0% of patients. There was no significant statistical difference between those patients with mild and severe carditis concerning the level of ESR, CRP, and ASO titers. There was also no significant statistical difference between the level of these parameters and the presence or absence of carditis, and the patient's age (≤8 years or >8 years old). 1999 5 01 11 14 http://mjiri.iums.ac.ir/article-1-965-en.pdf

By rotating the subjects with a string-activated rotating chair in opposite direction of the dominant side, the dominant side would be inhibited and simultaneously the subordinate ide would be stimulated. Eight patients with vestibular vertigo confirmed by ENG and rotatory test were subjected to a rotatory stimulus, the effect of which was evaluated by rotatory test. V mal of the two sides of all patients were compared before the stimulus and to, 40, and 70 minutes afterwards. The result indicate a significant difference between directional preponderance COP) values before and after. stimulation, especially at 70 minutes. The initial values of DP in 5 of 8. patients were out of the normal range and were significantly reduced to lower levels after timulation, especially after 70 minutes when DP fell within normal limits. In two of the remaining patient , a change in direction was observed at 40 minutes, and it remained '0 even after 7 minute in one of them. By minimizing the inequality between the vestibular discharge on the two sides, a reduction in vertigo intensity is expected 1999 5 01 5 10 http://mjiri.iums.ac.ir/article-1-964-en.pdf

The progressive nature of respiratory problems in these patients suggests that the immune system must be involved to Initiate a cascade which ends up causing lung injuries. To evaluate this, humoral immunity was assessed in 179 mustard gas victims in 1992. The patients were followed up for the next 4 years. These included 172 male and 7 female patients with a mean age of 33 years and an average of 6.1 years post-exposure to mustard gas. After physical examination and spirometriC evaluation, these patients were divided into 3 groups based on the severity of their respiratory problems, i. e. "severe" (group 1 ), "moderate" (group 2) and "mild" (group 3). IgG, IgA, C3 and C4 were measured using SRlD technique and IgE by ELISA. The results in each group were compared with the control group consisting of 49 healthy, randomly selected volunteers. Mean age was 32 years in this group. The results indicate that there is a significant fall in IgG, IgA, C3 and C41evels in group 3 (p=0 .009, 0 .01 , 0 .004, and 0.00 2, respectively) as compared to the control group. IgG had also dropped significantly in groups 2 and 1. On the other hand in group 3, 19.6% and 15.2% of patients had lower than normal IgG and IgA levels, respectively. In group 2, 7.7% of patients had low IgG and 5.8% had low IgA levels. These figures were 10 % and 3.8% for IgG and IgA in group 1. Of a total of7 patients in group 3 with low IgA levels, four patients also had low IgG levels. Two of these patients gradually developed more serious rspiratory problems and were classified as group 1 after two years. We conclnded that: 1) mildly injured patients (group 3) have lower IgG and IgA as well as C3 and C4 levels, and 2)among these patients those who demonstrate low IgG levels are more prone to develop progressive respiratory problems in the future.
