Aberrant benign thyroid masses may present as either an unrelated autopsy finding or with symptoms such as dyspnea, hemoptysis or adult -onset asthma. There is no place for medical management in the therapy of these lesions, although the appropriate surgical procedure is not clearly established. In this article a patient with respiratory distress and subglottic goiter is presented. She had subtotal thyroidectomy performed for goiter about 10 years ago. She was managed with tracheotomy and submucosal resection of subglottic thyroid tissue, followed by iodine ablation therapy and thyroid hormone replacement.

The adult form of the worm usually lives in the human intestine. Biliary complications due to ascaris infestation are uncommon but are becoming an important clinical problem, as fatal cases have been reported in the literature. Many authors have recommended traditional surgical treatment for removal of the worms. Since the development of endoscopy and related techniques, it has become possible to treat biliary ascariasis endoscopically. In this article, we have presented a case of biliary ascariasis which was diagnosed with ultrasonography and confirmed with ERCP. We have also assessed the role of endoscopy in the diagnosis and treatment of this disease in the literature.

The vertebral column, especially the llUllbar zone, is one of the rarest sites to be involved by paragangliomas. These lesions may have secretory functions and produce symptoms and signs mimicking cathecholamine oversecretion as was noticed in our case. A 60-year-old woman with a sacral mass, backache, and cauda equina syndrome along with arterial hypertension is being presented who had been managed with antihypertensive medications. Magnetic resonance imaging revealed involvement of sacral canal and L5 and S 1 bodies producing a soft tissue bulge near the right buttock and computed tomography showed a destructive sacral lesion. Surgery was performed to resect the turnor mass and surprisingly the postoperative blood pressure reached the normal range and henceforth antihypertensive therapy was withheld. Tissue diagnosis of paraganglioma was made on the basis of histopathological examination and ascertained by immunohistochemical study for chromogranin, neuron specific enolase, synaptophysin and S 1 00 protein. One month later the tumor site was subjected to radiation for any remnants following surgery. After two years, the patient was found to be doing well and had been normotensive Without medications. Spinal paragangliomas are treated with total excision and irradiation for residual tumor, if present. The role of immunohistochemistry could not be overemphasized for diagnostic confirmation.

The injury is a result of late inflammation, which is mediated by prostaglandins. Theoretically, inhibition of prostaglandins by reagents such as indomethacine could result in alleviation of clinical adverse effects. In this study, the protective effect of topically applied indomethacine against sulfur mustard toxicity was assessed on the rabbit eye. Ocular toxicity was studied by using light microscopy, electron microscopy and visual inspection methods. Methods used in this assay showed that 100 µL of indomethacine solution (0.5% W N) two hours before exposure and throughout the experiment could markedly decrease the toxic effects of mustard.

However it has also been speculated that an ability to suppress aerobic respiration and ATP utilization could be a protective response to prolonged hypoxia. Having the role of the cytochrome oxidase enzyme in mind, one can ask if its inhibition by using cyanide has a role in improving the heart's function after the cardioplegic period. In order to answer this question, the present study was carried out on two groups of rats. The test and control groups included 10 male rats. Each animal in both test and control groups received cyanide (LP., 1.6 mg/kg/ day) and saline (1 ml/day) respectively, and each heart experienced three stages: 1) normal activity, 2) cardioplegia, and 3) reperfusion stage. St-Thomas II cardioplegic solution was used while it contained 0.5 mmol/L cyanide in the test group. The results indicated that recovery percentage in the reperfusion stage, for the De.L. v.P. and dp/dt parameters were significantly higher in the test [(14S.1%±11.97) and (l30.97%±9.619)] than the control group [(91.62%±4.S9) and (96.1 %±4.91)] [(P<0.01) and (p<0.005)]. H.R. parameters, the rate of coronary solution flow, the variations of left ventricular diastolic pressure in the reperfusion period and tissue pathologic damages did not show significant differences between the two groups. These results indicated that the application of cyanide in cardioplegic solution induces an improvement of cardiac function in relation to the control group which is likely to be due to the impact of cyanide on cytochrome oxidase.

These are Entamoeba dispar for the nonpathogenic and E. histolytica for the pathogenic fonn. Differentiation of these two organisms is of great clinical importance since they are morphologically indistinguishable and both fonns can infect the human intestinal cavity. A study was carried out to differentiate E. histolytica from E. dispar by polymerase chain reaction (PCR) using two sets of primers (p11plus p12 and p13 plus p14) specific for either species of ameba. The extracted DNA was used for the identification of the species in the stool and culture media by PCR. A total of 16 samples, cysts and trophozoites, were analyzed. In all, 15 samples reacted with E. dispar primers, resulting in the expected 10 I-bp PCR products however, none of these reacted with E. histolytica primers. Only one sample reacted with E. histolytica primers. Because of high sensitivity of the PCR method and the high risk of laboratory contamination during processing and extracting DNA and its polymerization, and because of many existing cultures of E. histolytica in the same laboratory, the chance of contamination can not be ruled out in the single case of E. histolytica. This preliminary study could be an introduction for a PCR -based epidemiological study to detennine the importance of E. histolytica in Iran. 2001 2 01 369 372 http://mjiri.iums.ac.ir/article-1-841-en.pdf

Lateral saphenous veins were obtained from male rabbits weighing 3.20-4 kg, which were killed by overdose with pentobarbitone sodium (i.v. injection). They were easily dissected out and placed in cold, oxygenated modified Krebs-Henselite solution (Krebs). Each preparation was cut transversely into 3-4 mm rings and suspended between thick wire supports. The vein rings were mounted in 10 mL isolated organ bath, bathed in Krebs maintained at 37°C and gassed with 95% 02 plus 5% CO2, Cumulative concentration-response curves (CCRC) were constructed by increasing the concentration of the agonists in half-log increments. The preparations were left for a further period of 45-60 min before re-exposure to the agonist. Competitive antagonists like prazosin and rauwolscine were incubated in preparations at least for 45 minutes prior to the onset of a second CCRC. The strategy was based on using the a1-adrenoceptor selective agonist, phenylephrine (PE). Prazosin, an α1 -adrenoceptor selective antagonist, competitively inhibited contractile responses to phenylephrine with a pA2 value of 8, WB-41 0 1 had a pA2 of 8.6 but a low Schild plot slope, while low potency was found with 5MU (PA2 7.2) and HV -723 (pA2 7.97). This data is not consistent with a definitive for αlA or αlN and taken alone the evidence from prazosin is in favour of αIL' However the selective α2- adrenoceptor antagonist delequamine inhibited phenylephrine-induced contractions. Overall the data is consistent with phenylephrine-induced contractions being mediated by a,- and a2 -adrenoceptors. The best estimate of the subtype of ajadrenoceptor mediating contraction is aiL due to the relatively low absolute pA2 values for prazosin. α1-adrenoceptor subtypes phenylephrine prazosin delequamine WB-4101 SMU HV-723. 2001 2 01 363 367 http://mjiri.iums.ac.ir/article-1-840-en.pdf

Following in vivo priming with two purified protein derivatives (one from a virulent WHO strain and the other from an avirulent strain), T cell enrichment was performed on murine spleen cells and followed by in vitro restimulation with SEB. Flow-cytometry studies were done to monitor the expression ofCD44 or CD45RB. Results indicate that primed or memory CD8+ cells do not display any significant change in the expression ofCD45RB. The expression ofCD44 exhibited significant variations among unprimed and primed mice and between different antigens. We were also able to see differential expression relevant to the virulence of the bacterial strain. This study suggests that by activation of those populations ofCD8+, CD44+ cells, resistance to virulent bacteria occurs. 2001 2 01 359 362 http://mjiri.iums.ac.ir/article-1-839-en.pdf

ESSENTIAL OIL ON RAT ISOLATED ILEUM IN VITRO H SADRAEISADRAEI hsadraei@yahoo.com V HAJHASHEMI A GHANNADI M MOHSENI Teucrium polium L. (Lamiaceae) is used in the traditional medicine of Iran for the treatment of disorders of the gastrointestinal tract. The essential oil from the aerial parts of T polium was assessed for antispasmodic activity and compared with the effect of atropine and dicyclomine. Acetylcholine and KC I were used for induction of contraction on rat isolated ileum. Teucrium polium essential oil (TPEO) at concentrations of 8.6 to 34.4 µg/mL attenuated the maximum inducible response to acetylcholine concentration-response curve. It also inhibited the response to 80 mM KC I in a concentration dependent manner (pD2= 1.2±0 .13). Dicyclomine (3.46 & 34.6 ng/mL) also reduced the response to acetylcholine on rat isolated ileum and inhibited KC1-induced contractions while atropine only inhibited the response to acetylcholine. This study shows that TPEO is a relaxant of rat isolated ileum and may have some clinical benefits for gastrointestinal disorders such as colic. Teucrium polium L.

Animals were sensitized to B.C.G., trichophytin and mallein during the first four weeks. The diet was ad libitum during this period. After this "sensitization period" animals w er e tested intradermally with tuberculin, trichophytin and mallein. The number and diameter of positive delayed type hypersensitivity responses (antigenic and cumulative scores) were evaluated as an effector state of cell mediated immunity. Animals were fed low, adequate or high ascorbate diets (0.5, 2.0 or 50 mg ascorbate x 100g body wt-1xd-1) for the next four weeks. Antigenic and cumulative scores were evaluated after this period once again. Mean liver ascorbate paralleled dietary intake and the values obtained w er e significantly different in the three groups. Blood histamine was significantly depressed in the high ascorbate group compared to the adequate and low ascorbate groups, and liver ascorbate was inversely correlated to blood histamine levels (r= -0.97, p<0.001). Although mean antigenic and cumulative scores in the low ascorbate group were lower than those of adequate and high ascorbate groups, the differences were not significant. It was concluded that ascorbate may enhance immune function through detoxifying histamine, an immunodepressor compound. However, the immunostimulatory effect of ascorbate on cell mediated immunity was not confirmed in this study. In chronic ascorbate deficiency, there may be a predisposition to infectious diseases due to depressed immune function, at least because of disturbances in metabolism of other nutrients influencing immune responsiveness, especially iron and folate.

IZADPANAH Spillage of scoleces is a major problem in surgery of hydatid cysts, because each of them may develop into a new cyst if it settles on a suitable site such as the peritoneum. Many surgeons believe that scoleces in ruptured hydatid cysts of the liver containing bile are not able to develop new cysts, because bile kills thein. In order to prove this idea, the viability of scoleces in such cysts was assessed and the effect of bile on live scoleces of unruptured liver cysts of sheep and human beings was also assessed in the laboratory. It was concluded that bile is not scolecidal, and an unfavorable environment is the cause of death bf the •scoleces. Scoleces in ruptured cysts may be alive and able to develop a new cyst. Therefore the surgeon should use all necessary precautions to prevent spillage. Hydatid cyst scoleces bile. 2001 2 01 343 345 http://mjiri.iums.ac.ir/article-1-834-en.pdf

Ninety-four female-female twins who underwent a transabdominal ultrasound at the Royal Hospital for Women were sent a questionnaire asking about their birth details, feeding history as a baby, childhood illnesses and vaccination as well as exercise patterns. Seventy-seven subjects returned the questionnaire. All of the variables were studied in two groups of subjects those with ultrasound evidence of polycystic ovaries (US-PCO, n= 37) and those with normal ovaries (US-normal, n= 40). The data were also analyzed in a group of scan-discordant twins (7 pairs) in whom one of the twins had US-PCO and the co-twin had normal ovaries. Analyzing the data from the whole database suggested that US-PCO subjects had lower birth weight compared to US-normals. Vaccination against mumps was also found to be significantly higher in the US-PCO group compared with US-normals. Matched results for scan-discordant twins did not confirm these results. Other environmental variables such as feeding history, type of delivery, birth order and physical activity during the first 20 years of age did not seem to have any significant influence on the prevalence of PCO. No significant difference was found in childhood illnesses between the groups. In conclusion, this study examined the effect of some environmental factors during childhood and early adulthood. Analyzing the whole database and scan-discordant twins failed to show any particular environmental factor associated with PCO.

Idiopathic neonatal hepatitis was the most common cause of cholestasis, accounting for 48 cases with a rate of 3'8.70% in a total of 124 patients, followed by galactosemia in 29 patients (23.38%) and extrahepatic biliary atresia in 20 patients (16.12%). The prompt identification and diagnostic assessment of these infants are imperative to early surgical intervention (e.g. in biliary atresia) and specific medical therapy (e.g. in galactosemia) and in order to institute effective nutritional and medical support to allow optimal growth and development and prevent progressive liver disease and death.

In 78 renal failure patients who underwent hemodialysis, serum levels of zinc and copper were determined before and after first hemodialysis. Acute and chronic renal failure patients were found to have lower serum zinc levels before hemodialysis and higher levels after hemodialysis, while serum copper levels were found to be higher before hemodialysis and to increase further after hemodialysis. Disturbances in acid-base balance lead to acidosis which can alter the binding, transport and excretion of these elements. Dialysis fluid containing salts of trace elements may have also contributed to this alteration of trace element levels.

Centiles for MUAC and HC lie below the Netherlands and US subjects respectively. However, there is no suggestion of ill health for Iranian subjects. The use of locally based MUAC, HC, and CHC charts are essential for clinical work in Iran. Operational simplicity and measurement validity and accuracy suggest that monitoring these measurements should be performed both by health workers in the Iran primary health care system and by mothers for preventive measures as well as child health promotion and development. The paper concludes that the charts presented here are likely to be applied to the urban infant population of Iran due to its structural representativeness and sophisticated methodology. 2001 2 01 321 327 http://mjiri.iums.ac.ir/article-1-830-en.pdf

The patients were followed for 6 months and complications such as seroma, infection and relapse were evaluated. The incidence of seroma, infection and relapse after Z-plasty was 12%,3.3% and 3.6%, respectively. These results show that Z-plasty is an effective form of operation for pilonidal cyst treatment.

Those patients who were initially palliated with shunt were either referred from other centers for total correction, presented with cyanotic spells, or were shunted due to their severe and diffuse right ventricular outflow tract obstruction or pulmonary artery branch stenosis or hypoplasia. Hospital mortality and ratio of right to left ventricle pressure after correction were compared between the primary and the two-stage groups as early outcome indices. The patients were also divided to those who needed a trans-annular (TAP) or a sub-annular patch and were compared. In the primary group, 25 (37.3%) of the patients needed TAP, while in the two-stage group 28 (63.6%) needed TAP. Requirement for TAP was increased significantly with two-stage correction (p= 0.006, relative risk= 1.71, 95% CI= 1.16-2.5). Mortality was significantly higher in the primary group (p= 0.03, relative risk= 3.94, 95% CI= 0.93-16.76). In the primary group TAP significantly increased the mortality risk (p= 0.006, relative risk= 5.04, 95% CI= 1.5-16.89). In the two-stage group, there was no significant difference in the mortality rate between the patients with and without TAP. The TAP group had statistically significant less time interval between shunt and total correction. Our patients generally did better on two-stage repair, because of their older age at operation. The long period of low pulmonary blood flow has induced unbalanced. ventricles for them and exaggerated right ventricular outflow tract obstruction due to muscle hypertrophy. In such patients, shunting will prepare the left ventricle for accepting the extra blood volume that will reach it after total correction.

After an initial complete remission for a few months, most patients in advanced stages and a few cases in early stages developed recurrence for whom chemotherapy was started. The majority achieved remission again. After 3 years of follow 'up 18 of 26 patients were alive with no evidence of disease. As the behavior of this lymphoma is related to initial stage of disease rather than to Ki-l expression, radiation therapy may be an acceptable modality adjunctive to chemotherapy in patients with such lymphomas, particularly in those with localized disease for getting better disease control. 2001 2 01 307 309 http://mjiri.iums.ac.ir/article-1-827-en.pdf
