Rats were connulated and bilateral injection of vehicle (saline) and 5-HT2A- selective antagonist, ketanserin (0.6, 1.2 or 2.4 µg/0.5 µl) were injected through the connulae 30 miutes before training each day. Results indicated that direct ketanserin and pirenperone injection did not affect spontaneous alternation. They also did not show a significant effect on trials to reach criterion and errors made by animals throughout spatial discrimination and reversal learning and reversal stages. During extiction, no change was observed in the choice of the previously reinforced arm in both ketanserin and pirenperone groups. The slope of latency in highest dose of ketanserin (2.4 µg/0.5 µ/l) compared to the sham operated group but not in the pirenperone group.These findings suggest that 5-HT2A receptors blockade (ketanserin, not prienperone) in the CA1 region may decrease decision time and increase behavioural flexibility in T-maze https://acta.tums.ac.ir/index.php/acta/article/view/2471 https://acta.tums.ac.ir/index.php/acta/article/download/2471/2459

In this retrospective study we reviwed epidemiological and clinical findings, treatment results and prognostic factors of 97 patients with CM admitted in Imam Khomeini hospital for the last 10 years. Important etiological factors in this study included: Mycobacterium Tuberculousis (8.2%) Brucellae SP (5.2%), malignancies (1%) and unknown (85.5%); the sexual ratio was 2:1 (Male/Female) and the most common clinical manifestations were: fever, headache, cranial and motor neuron involvement, seizure and ataxia. Treatment regimens used included antituberculosis agents with or witout corticosteroids, in which the prognosis was better in patients who had been treated with antituberculosis agents alone. The mortality rate was 22.7%, which was in accordance with other studies. We suggest using of antituberculosis treatment alone in comparison with antituberculosis and corticosteroid. Last but not least a double blind randomized clinical trial for a longer period is needed to further substantiate the results of this study. https://acta.tums.ac.ir/index.php/acta/article/view/2473 https://acta.tums.ac.ir/index.php/acta/article/download/2473/2461

In the absence of capsular support, anterior chamber lenses have been widely used. On the other hand intraocular lens implantation of scleral sutured posterior chamber intraocular lens during penterating keratoplasty or insufficient iris support is recommended. The purpose of this study is to evaluate the clinical outcome and complication in 17 patients who underwent scleral-fixation of an intraocular lens.We studied prospectively the results of posterior chamber intraocular lens implantation by scleral fixation in 17 eyes of 17 patients without a complete posterior lens capsule support at farabi Eye Hospital. Uncorrected visual acuity improved from counting finger to 20/40 or better in 9 eyes (53 percent). The following complications were observed during the mean postoperative follow-up of 7.2 (range 3-12) months; increased intraocular pressure in 5 eyes, vitreous hemorrhage and icr hyphema in 2 eyes, cystoid macular edema (CME) and vitritis in one eye, and endophthalmitis and retinal detachment in one eye. Posterior chamber intraocular lens implantation by scleral fixation is a relatively safe procedure and can be recommended for many patients https://acta.tums.ac.ir/index.php/acta/article/view/2475 https://acta.tums.ac.ir/index.php/acta/article/download/2475/2463

A new surgical excision is being introduced which is called transverse cupid bow-like elliptical incision. The previous traditional method was a simple elliptical excision. The new method gives the cupid’s bow a more natural apperance and keeps the normal shape of the upper lip.Surgical excision with transverse cupid bow-like elliptical excision in undertaken with regional nerve block anesthesia.It was interesting to observe that in the upper lip, the buccal portion of the double lip appeared on either side with a midline constriction. Surgical excision with the new method under regional nerve block anesthesia provides good result. The embryology and clinical appearances are discussed with a review of the literature.Congenital doble-lip anomaly is rare, and 5 cases are beint reported. All the patients were males, and there was no hereditary history, relation of the parents or any obvious acquired etiologic factor for the development ot this molformation. https://acta.tums.ac.ir/index.php/acta/article/view/2476 https://acta.tums.ac.ir/index.php/acta/article/download/2476/2464

This is a prospective study. In this study the mean (± standard error) maternal serum DHEA sulfate levels of 90 singleton pregnant women in 3 groups with spontaneous labor, need for augmentation and need for induction were compared.Pregnancies complicated by diabetes mellitus, hypertension, fetal growth restriction, tobacco consumption, corticosteriod use or chorioamintis were excluded. Bishop score of all cases was less than 5. Serum DHEA sulfate levels were measured by radioimmunoassay. Dehydroepiandrosteone sulfate levels and other obstetric variables were correlated retrospectively with the clinically determined requirements of oxytocin augmentation of labor, and the outcome of each induction attempt. The t-test, Variance analysis Kruskal –Wallis test, Mann-Whitney test, chi-square (X2) distribution, linear correlation and regression were used for statistical analysis.

An oraganic extract of the powdered leaves was analysed for the photosensitive compounds. Al least six different photosensitive compounds.Al least six different photosensitive components were detected in the TLC chromatogram of the extract. Two of the most photosensitive components were purified compounds into two different purifed plasmid DNAs were observed. In addition, photoreacted DNA samples were easily fragmented by heat treatment in comparision to control samples not treated with the furocoumarins. https://acta.tums.ac.ir/index.php/acta/article/view/2478 https://acta.tums.ac.ir/index.php/acta/article/download/2478/2466

The economical losses in domestic animals are considerable. In the recent decade there were two major outbreaks of human fasciolosis in the Caspian region, northern part of Iran with 7000-10000 infected cases. Sicne it is impossible to diagnose fasciolosis in acute phase using coprological methods and even in chronic phases its sensitivity is low, evaluating and establishing a reliable and cost-effetive test is indispensable and notewortly.In the present survey, we produced and examined the sensitivity and specificity of liver fluke homogenate (LFH) , excretory-secetory (ES) and cysteine proteinase (CP) antigens of F. hepatica using IgG-ELISA test. A 25-27 kilo Dalton coomassie blue-stained band was observed and using of specific inhibitors indicated that this antigen belongs to the class of cysteine proteinase. The sensitivity of LFH, ES and CP antigen in IgG-ELISa was 100% for each, while their specificity was 97.8%, 98.8% and 98.8% respectively. There was a significant difference in mean OD values between cases of proven fasciolosis and other true negative cases, including healthy control individuals and patients with other parasitic diseases.This present report is the first to demonstrate the purification and evaluation of F. hepatica cysteine proteinase antigen by IgG-ELISA test for the diagnosis of fasciolosis in Iran. In conclusion, the IgG-ELISa using ES and CP show high sensitivity and specificity and would be a valuable tool to diagnose human fasciolosis in Iran, particularly in endemic areas. https://acta.tums.ac.ir/index.php/acta/article/view/2479 https://acta.tums.ac.ir/index.php/acta/article/download/2479/2467

The histopathologic report confirmed the diagnosis. Pleomorphic adenoma is most common in salivary glands but very rare in sweat glands. Pleomorphic adenoma in sweat gland and the similar tumors of eccring sweat gland are described that bear a striking resemblance to pleomorphic adenomas of salivary gland. Upon closer examination, the tumor contained areas of apocrine decapitation secretory activity , and primitive hair follicles indicating cutaneous rather than mucosal origin. One year follow-up examination has revealed no evidence of recurrence. https://acta.tums.ac.ir/index.php/acta/article/view/2481 https://acta.tums.ac.ir/index.php/acta/article/download/2481/2469
