Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 !mso]> ject classid="clsid:38481807-CA0E-42D2-BF39-B33AF135CC4D" id=ieooui> Background: Ovarian cancer is the leading cause of death among all gynecologic cancers in developed countries. The standard treatment for advanced ovarian cancer consists of cytoreductive surgery associated with a platinum/paclitaxel-based chemotherapy. Over than 50% of patients with advanced ovarian cancer will develop recurrent disease. For those patients who have recurrence of disease at least six months after initial therapy, the paclitaxel- platinum combination has been shown to be a superior treatment to platinum monotherapy. However, many patients develop clinically relevant neurotoxicity, frequently resulting in treatment discontinuation. The efficacy and safety of an alternative regimen that dose not show significant neurotoxicity were evaluated by comparing gemcitabin- carboplatin with carboplatin in platinum sensitive recurrent ovarian cancer patients in a Gynecologic Cancer InterGroup trial in Canada and European Organization for research and treatment of Cancer Gynecological Cancer Group. But this study was not done in Iran.
Methods: We performed a study with escalating doses of gemcitabin combined with carboplatin in 21 patients. All patients who were treated in Vali-Asr hospital between 2003- 2005 evaluated. Gemcitabin with dose of 800mg/m2 was given on days 1, 8 and 15 followed by one week rest period for a 28 day cycle. Combine with carboplatin with AUC 4 given on day 2. All patients with surgically resected, histologically confirmed epithelial ovarian cancer and who had failed first- line platinum chemotherapy were allocated to this study.
Results: Median age was 49 years (range 23-78 years). Median follow-up was six months (range 4-22). Total of 87 cycles of chemotherapy were administered with median number of four (range 2-6 cycles). Thrombocytopenia (grade I) and leucopenia (grade I) were seen in 4.75% and 9.52% of patients.
Conclusion: Gemcitabin and carboplatin Combination was tolerated in patients with recurrence of ovarian cancer.

Volume 79, Issue 8 (November 2021)
Abstract
Background: Otitis is the most common infectious disease of the ear with internal and external cranial complications. If the infection is in the middle ear, it causes otitis media. If the infection is in the external ear, it’s along with otitis externa (OE). Different types of otitis media include acute otitis media (AOM), chronic otitis media (COM) and Otitis media with effusion (OME). This study aimed to investigate the different types of otitis and its symptoms.
Methods: This cross-sectional study was conducted from March 2019 to February 2020 for 200 patients who have been referred to the ENT center of Shafa hospital, Kerman, Iran. Sampling was conducted with ease and no need for specified sampling distribution. The type of otitis was written in a questionnaire by the physician after the examination. The present research investigated types of otitis along with its symptoms. Also, their demographic information was determined.
Results: This study was done among 200 patients. 106(53%) participants were diagnosed with external otitis and the most common symptoms include discharge from the ear, inflammation and pain of the ear. 53 patients (26.5%) had acute otitis media with the most common symptoms of tympanic membrane color change and otalgia. 22 patients (11%) were diagnosed with chronic otitis media. So, perforation of the tympanic membrane and otorrhea were considered as the most common symptoms for these patients. 9(9.5%) of participants had otitis media with effusion that aural fullness and reduction of hearing were the most common signs. In this research, most of the patients were between the age of 11 to 30.57% of patients in this study were men and 43% were women. Most of the patients were between the age of 30-40 and the least number of patients were over the age of 70. Among the 200 patients, most of them lived in cities and provinces rather than villages. 67.5% of patients didn’t have an academic certificate.
Conclusion: Considering the high prevalence of otitis among patients with ENT disorder, it was recommended that otitis should be recognized and cured.

Comparison of the thickening of donor skin graft with conventional method (using vaseline gas) and platelet-rich plasma topical application
Vahid Hatami, Hamed Tavan, Sajad Hatami , Ali Delpisheh, Mina Mamizadeh,
Volume 79, Issue 10 (January 2022)
Abstract
Background: Healing involves complex processes that are not yet fully known. The wound healing process consists of three stages. In all these stages, normal wound healing requires platelet activation, release of cytokines and growth hormones, and chemotaxis and cell differentiation. Platelets play a key role in homeostasis and wound healing and growth factor production of more than 30 carried out by them. Platelets regulate the healing process with their chemotactic effect. Antilogous PRP platelet count in about 3 to 5 times increase and consequently also increases the number of growth factors, for this reason, they are being used in surgical procedures and clinical therapy.
Methods: At Ilam Medical Center in Imam Khomeini Hospital, 20 patients with two similar donor graft sites were gradually selected to participate in a clinical trial from January to March 2017. The two regions have the same skin graft patients, an area of Honor conventional and other areas with the topical administration of platelet-rich plasma That immediately after surgery and in the days after the fifth and eleventh, eightieth and after washing the wound with a topical serum Physiology rubbed on the wound and thus treated The rate of wound healing clinically and using X-ray photo-checked and compared.
Results: Seven are male and thirteen are female and the age range of patients is between 17 and 67 years. After collecting wound healing times in two groups, we used the means comparison method to evaluate the effect of PRP on wound healing rate and analyzed the results (T-Test). Because the data followed a normal distribution, we used the Independent T-test method, which resulted in 0.416, which was higher than the alpha level equal to 0.05.
Conclusion: In this study, we found that PRP had a positive effect on wound healing time and increased the speed of wound healing. It is suggested that the effect of the PRP method on various organs that have not been tested before, be discussed in future studies.
 

Investigating the effect of insect body extracts (their products) and some arthropods in inhibiting the growth of cancer cells or tumours (breast cancer cell line/MCF7)

Abstract
Background: Insects and arthropods, along with their products, have been used as medicinal sources since ancient times, that is called entomotherapy. Cancer is one of the major problems in medical science, for which a drug has not yet been discovered to control it quickly and accurately. Arthropods have been medicinal sources since ancient times and they especially Insects have a high potential for insect therapy because of the biodiversity. This research investigates the effect of insect body extracts and arthropods in inhibiting the growth of cancer cells or tumours, specifically on the breast cancer cell line, MCF7002E
Methods: The basic and applied study was conducted in Isfahan from 2018 to 2023. In this research, six species of insects, namely Gryllotalpa sp., Polyrhachis sp., Dolichovespula sp., Apis mellifera, Periplaneta americana, Drosophila melanogaster, and one species of Chilopoda, Scolopendra sp., were used. The samples were washed with distilled water and 70% alcohol, then frozen and powdered and prepared in 1% DMSO at eight concentrations of 62.5, 125, 250, 500, 1000, 2000, 4000, 8000 μg/ml and were evaluated for the control of two lines of breast cancer cells MCF-7 by the MTT test was performed to check the effect of doses. The affected doses of insects and centipedes were performed in 6 replicates and three times to MCF-7 cells. IC50 and LD50 were calculated by Prism version six software to check the effect of concentrations determine the effective dose and choose the best extract to control the growth of MCF-7 breast cancer cells.
Results: Scolopendra sp., Drosophila melanogaster, Periplaneta americana, Polyrhachis sp., Apis mellifera, and Gryllotalpa sp. are the most effective species, respectively, in inducing apoptosis and cell death in MCF-7 cancer cell line. Dolichovespula sp. had the least effect. Scolopendra sp. at a concentration of 500 μg/litre induced cell death in more than 50% of MCF-7 cancer cells.
Conclusion: The results of the application of seven different genera of arthropods and insects showed that these genera have excellent therapeutic potential, particularly in the treatment of MCF-7 cancer cells.
