Comparison of the pregnancy outcomes between the medical and surgical treatments in tubal ectopi pregnancy

Background: Various treatments have been proposed to treat ectopic pregnancy, but their impact on future pregnancies is still the subject of controversy. Objective: The aim of this study is to compare the medical and surgical treatment methods and their impact on the subsequent fertility results and complications in women with a history of ectopic pregnancy. Materials and Methods: In this analytical, cross-sectional study, 370 women with the history of ectopic pregnancy, (treared with single dose of methotrexate or salpingectomy by laparotomy), that referred to Al-Zahra Hospital, Rasht, Guilan between 2009 to 2013 were enrolled. 147 women responded to the phone call. The age, the number of women that needed to drug for pregnancy, fertility rate and the fertility outcomes were studied. Result: 147 women responded to the call and between them, 114 women tried to get pregnant again after the ectopic pregnancy treatment. They were agreed to the participate in the study. The mean age of the patients was 28.56±5.63 yr. The fertility rates in the medical and the surgical groups were 56.6 and 47.61, respectively (p=0.141). There were no significant differences in the poor consequences of pregnancy among the two groups; ectopic pregnancy (p=0.605), miscarriage (p=0.605), and prematuredelivery (p=0.648). 15.1 in the medicinal group and two patients 12.5 in the surgical group had received fertility treatment in order to get pregnant (p=0.135). There was no significant difference in two groups. Conclusion: It seems that surgical treatment depending on the underlying variables of each patient, can be used such as medical treatment, without worrying about its effect on fertility. © 2018, Research and Clinical Center for Infertitlity.

Influence of zinc incorporation on microstructure of hydroxyapatite to characterize the effect of pH and calcination temperatures

AbstractThis work was focused to study the existence of Zn2+ in structure, chemical composition as well as particle and crystallite size of hydroxyapatite (HAp) to characterize the effect of pH of the solution and calcination temperature. Non-stoichiometric HAp (nHAp) powders containing 4at.% zinc fraction were synthesized via solution–precipitation method. In order to characterize the effect of pH (values: 9 and 10.5) and two calcination temperatures (550 and 1000°C) on chemical composition, molecule internal bonds, particle and crystallite size of the synthesized powders, XRD, EDS, FTIR and SEM techniques were utilized. The results showed that zinc cations could be incorporated in the HAp atomic structure to form low crystalline single phase of nHAP. The pH adjustment to 10.5 caused the formation of powders with smaller particle and crystallite sizes. The results also indicated that calcination temperature up to 1000°C caused decomposition of zinc doped nHAp to β-tri calcium phosphate and tri zinc calcium phosphate phases which are used to control the speed of biodegradation

Study of antioxidant activity and free radical scavenging power of Rheum Ribes flower extract

In recent years, the use of synthetic antioxidants and the degradation products derived from them is limited, because they are toxic and carcinogenic. So, studying on the use of natural antioxidants to replace the synthetic antioxidants is very important. Natural antioxidants are healthier and have more benefits and fewer harmful side effects. In this study, first, the Rheum Ribes of flower was extracted by maceration method with methanol. The extract’s phenolic compounds and inhibitory activity of free radicals were evaluated in different concentrations (100, 150, 200, 250 and 300 ppm) by Folin-Ciocalteu method and DPPH test, respectively and then, compared with the synthetic antioxidant of BHT at the constant concentration of 200 ppm. The results showed that the highest antioxidant properties of the extract was related to the concentration of 300 ppm and also the concentration of 250 ppm of the extract of Rheum Ribes of flower was equivalent to a concentration of 200 ppm of BHT in terms of free radical scavenging properties.Keywords: Rheum Ribes flower, Free radical scavenging power, Natural antioxidants, Phenolic compound

Epidemiological study on some environmental and management parameters affecting on WSD occurrence in Fenneropenaeus indicus and Penaeus vannamei

For the first time white spot disease (WSD) was reported in shrimp farms of khoozestan province, in southwest of IRAN in 2002. Then in 2005 the neighbor province, boushehr, was contaminated. In 2008 WSD outbreak reported in sistan-bloochestan province in southeast of Iran. In 2015 all of southern shrimp farms of country except Hormozgan, the middle southern province, which has remained free of WSD, are being contaminated. White Spot disease suspended shrimp culture in thousands hectares of shrimp farms. Considering that white spot disease has not been observed in Hormozgan province yet, the question is; to what extent environmental and management factors participated in preventing WSD outbreak or cause WSD outbreak. In this study (20102012), the effects of environmental factors and management, stressors that decrease immune system function of shrimp are discussed. In addition, the role of pathogen as the main factor of outbreak is discussed. The goal of this study is to define environmental parameters and management practices associates with outbreak of white spot disease in affected provinces and discover reasons of being Hormozgan province free of this disease. In this study the role of the local environmental factors and management practice stressors in susceptibility to WSD was determine. Both the effects of environmental factors in water of ponds including total ammonia, nitrogen, dissolved oxygen, pH, salinity, transparency, and temperature and management issues related to biosecurity are studied. There were overlaps on physical and chemical parameter values obtained in clear areas with contaminated areas .Results of the data analysis suggest that lack of association with WSD incidence was 7 times greater than WSD incidence despite of disease outbreak in sistan-bloochestan province, so other sources of white spot disease virus incidence was suspected in affected areas. Histopathological examinations and polymerase chain reaction (PCR) tests during project performance did not reveal white spot disease virus evidences in post larvae examined from khoozestan province stocked in farms but disease outbreak was happened in that farms , so we suspected to management practice include feed , pond preparation and carrier of disease. Recorded values of temperature and salinity in some months during inspection in Hormozgan province specified stressful condition that may lead to WSD outbreak, however the disease did not appear. Therefore the hypothesis that the water physical and chemical conditions are reasons to prevent disease outbreak in Hormozgan province is being rejected. The policy of Hormozgan’s fishery authorities, to replaced Fenneropenaeus indicus with specific pathogen free Litopenaeus vannamei, that is more resistant to some of diseases, before incidence of WSD in farms and to before being endemic in the Hormozgan province, made an advantage compare to affected southern provinces that introduced Litopenaeus vannamei after WSD prevalence to their farms. However it does not guarantee to maintain current trend of being Hormozgan province farms free of white spot disease. Therefore establishing the principals of biosecurity are strongly emphasized. Strategies taken by the proficient authorities in preparation of SPF shrimp broodstock can be the most important factor in preventing WSD. Regarding biosecurity principals purchased feed must be free of shrimp head powder. Construction the new shrimp farms should be as far as it could be away from contaminated areas

Evaluation of sesamum gum as an excipient in matrix tablets

In developing countries modern medicines are often beyond the affordability of the majority of the population. This is due to the reliance on expensive imported raw materials despite the abundance of natural resources which could provide an equivalent or even an improved function. The aim of this study was to investigate the potential of sesamum gum (SG) extracted from the leaves of Sesamum radiatum (readily cultivated in sub-Saharan Africa) as a matrix former. Directly compressed matrix tablets were prepared from the extract and compared with similar matrices of HPMC (K4M) using theophylline as a model water soluble drug. The compaction, swelling, erosion and drug release from the matrices were studied in deionized water, 0.1 N HCl (pH 1.2) and phosphate buffer (pH 6.8) using USP apparatus II. The data from the swelling, erosion and drug release studies were also fitted into the respective mathematical models. Results showed that the matrices underwent a combination of swelling and erosion, with the swelling action being controlled by the rate of hydration in the medium. SG also controlled the release of theophylline similar to the HPMC and therefore may have use as an alternative excipient in regions where Sesamum radiatum can be easily cultivated
