Background: Thalassemia constitutes a major public health problem causing a significant burden on children and their families. Zinc deficiency plays an important role in many thalassemia-related complications like growth retardation, hypogonadism and delayed puberty which are frequently noted in adolescent age. Although zinc is supplemented to thalassemic patients visiting Day Care Center, Yangon Children Hospital (YCH), Myanmar, a report concerning serum zinc level of these patients is still lacking. This study, therefore, aimed to assess serum zinc status in thalassemic adolescents attending Day Care Center, YCH. Materials and Methods: This hospital-based cross-sectional study was conducted on 99 thalassemic adolescents. Mean age of diagnosis was 5.1±2.1 years. Non-fasting serum zinc concentration was determined by atomic absorption spectrophotometry. According to National Health and Nutrition Examination Survey data, zinc deficiency was defined as serum zinc concentration < 66 μg/dL (female) and < 70 μg/dL (male). Results: Serum zinc concentration (μg/dL) was 57.35 (47.30-80.14) (median, interquartile range) with maximum, 195.05 and minimum, 28.83. Zinc deficiency was observed in 69.7% (69 out of 99; 35 males and 34 females) of the patients. The associations of zinc deficiency with gender, phenotype and the use of chelator were nonsignificant (P>0.05). Conclusion: In spite of zinc supplementation, nearly 70% of the thalassemic adolescents showed zinc deficiency. Zinc deficiency in these adolescents might not be related to gender, phenotypes or the use of chelator. Poor compliance to take zinc supplementation and/or irregular blood transfusion could partly be attributable to zinc deficiency in these adolescents. Providing health education on the importance of regular intake of adequate zinc is advisable and periodic evaluation of zinc levels is recommended for thalassemic adolescents.
背景:地中海贫血是一个主要的公共卫生问题,给儿童及其家庭带来了巨大负担。锌缺乏在许多地中海贫血相关并发症中起着重要作用,如生长迟缓、性腺功能减退和青春期延迟,这些并发症在青少年时期经常出现。尽管访问缅甸仰光儿童医院日托中心的地中海贫血患者补充了锌,但关于这些患者血清锌水平的报告仍然缺乏。因此,本研究旨在评估YCH日托中心地中海贫血青少年的血清锌状况。材料和方法:这项基于医院的横断面研究对99名地中海贫血青少年进行了研究。平均诊断年龄为5.1±2.1岁。采用原子吸收分光光度法测定非空腹血清锌浓度。根据国家健康和营养检查调查数据,缺锌定义为血清锌浓度<66μg/dL(女性)和<70μg/dL(男性)。结果:血清锌浓度(μg/dL)为57.35(47.30-80.14)(中位数,四分位间距),最大值为195.05,最小值为28.83。69.7%的患者(99人中有69人;35名男性和34名女性)出现锌缺乏。锌缺乏与性别、表型和螯合剂使用的相关性不显著(P>0.05)。结论:尽管补充了锌,但近70%的地中海贫血青少年表现出锌缺乏。这些青少年的锌缺乏可能与性别、表型或螯合剂的使用无关。对补锌依从性差和/或输血不规律可能部分归因于这些青少年的锌缺乏。建议就定期摄入充足锌的重要性进行健康教育,并建议地中海贫血青少年定期评估锌水平。

Cardiac disease is the main cause of death in both forms of thalassemia; thalassemia major (TM) and thalassemia intermedia (TI). Pulmonary hypertension (PH) is one of the cardiopulmonary morbidities with high mortality that, if not treated, may trigger right-sided heart failure and premature death. PH is defined as a mean pulmonary artery pressure of ≥25 mmHg at rest or ≥30 mmHg during exercise. The prevalence of PH is known to be higher in TI than in TM. Moreover, the pathophysiology of PH in thalassemia appears to be sophisticated and complex. Risk factors for occurrence of PH consists of non-transfusion dependent thalassemia (NTDT), sub-optimally transfused transfusion dependent thalassemia (TDT), splenectomy, thrombocytosis, anemia, NRBC ≥ 300 × 106, iron accumulation, history of thrombosis and older age. Other parameters which aggravate the risk of PH include hemolysis, oxidative stress, hypoxemia, alteration of erythrocyte membrane, decline of nitric oxide biological availability, arginine abnormal regulation and arginase excess. The screening method for PH is Doppler echocardiography but the gold standard for detection of PH is right heart catheterization (RHC). Current medical therapeutic options in PH comprise hydroxyurea, LCarnitine, sildenafil, calcium channel antagonists, endothelin 1-receptor blockers and prostacyclin agonists. The only curative surgical method for the refractory and severe cases of PH is pulmonary endarterectomy. In this article, the etiology, pathophysiology, diagnostic methods and novel therapies of thalassemia associated PH are discussed.
心脏病是导致这两种地中海贫血死亡的主要原因;主要地中海贫血(TM)和中间地中海贫血(TI)。肺动脉高压(PH)是一种高死亡率的心肺疾病,如果不治疗,可能会引发右侧心力衰竭和过早死亡。PH定义为休息时平均肺动脉压≥25 mmHg或运动时平均肺血管压≥30 mmHg。众所周知,TI患者的PH患病率高于TM患者。此外,地中海贫血患者的PH病理生理学似乎复杂而复杂。PH发生的危险因素包括非输血依赖性地中海贫血(NTDT)、次优输血依赖性贫血(TDT)、脾切除术、血小板增多症、贫血、NRBC≥300×106、铁积聚、血栓形成史和年龄较大。其他加重PH风险的参数包括溶血、氧化应激、低氧血症、红细胞膜改变、一氧化氮生物有效性下降、精氨酸异常调节和精氨酸酶过量。PH的筛查方法是多普勒超声心动图,但检测PH的金标准是右心导管插入术(RHC)。目前PH的药物治疗选择包括羟基脲、左旋肉碱、西地那非、钙通道拮抗剂、内皮素1受体阻滞剂和前列环素激动剂。对于难治性和严重的PH病例,唯一的治疗方法是肺动脉内膜切除术。本文对地中海贫血相关PH的病因、病理生理学、诊断方法和新的治疗方法进行了讨论。

Background: Human platelet antigens (HPAs) are part of platelet GP complexes have the potential to contribute to the autoantibody production. Moreover, these antigens demonstrate different patterns of distribution on different ethnic groups and variation in some types of diseases. This study was objected to determine the incidence of HPA-1 to -5 and -15 polymorphisms in the Iranians suffering from primary Immune thrombocytopenic purpura (ITP). Materials and Methods: In this case-control investigation, 30 patients by definite primary ITP were randomly selected and enrolled in the study. HPA genotyping was performed implicating by the Single Specific Primer PCR (SSP-PCR). For the control group, data of recently published gene polymorphism among Iranian Blood donors were deployed for comparison. Results: The incidence of HPA-1 to -5 and -15 polymorphisms in the Iranian patients with primary ITP was found to be: HPA-1a/1a: 0.933, HPA-1a/1b: 0.067, HPA-2a/2a: 0.133, HPA-2a/2b: 0.867, HPA-3a/3a: 0.2, HPA-3a/3b: 0.533, HPA-3b/3b: 0.267, HPA-4a/4a: 1, HPA-5a/5a: 0.967, HPA-5a/5b: 0.330, HPA-15a/15a: 0.166, HPA-15a/15b: 0.667 & HPA-15b/15b: 0.167. Conclusion: This study provides special new data on the distribution of HPA allele among the Iranians ITP patients.Furthermore, it might useful toccharacterize understanding more presizely about ITP and HPA distribution. However, further studies concerning platelet immunology are needed to do help on best practice on management of immune diseases triggered by platelet antibodies.
背景:人血小板抗原(HPAs)是血小板GP复合物的一部分,有可能促进自身抗体的产生。此外,这些抗原在不同种族群体中表现出不同的分布模式,在某些类型的疾病中表现出差异。本研究旨在确定伊朗原发性免疫性血小板减少性紫癜(ITP)患者HPA-1至-5和-15多态性的发生率。材料和方法:在本病例对照研究中,随机选择30例明确原发性ITP患者参加研究。HPA基因分型采用单一特异性引物聚合酶链式反应(SSP-PCR)进行。对照组采用最近公布的伊朗献血者基因多态性数据进行比较。结果:伊朗原发性ITP患者中HPA-1至-5和-15多态性的发生率分别为:HPA-1a/1a:0.933、HPA-1a/1b:0.067、HPA-2a/2a:0.133、HPA-2a/2b:0.867、HPA-3a/3a:0.2、HPA-3a/3b:0.533、HPA-3b/3b:0.267、HPA-4a/4a:1、HPA-5a/5a:0.967、HPA-5a/5b:0.330、HPA-15a/15a0.166、HPA-15a/15b0.667和HPA-15b/15b0.167。结论:本研究为伊朗ITP患者HPA等位基因的分布提供了新的资料。此外,更深入地描述对ITP和HPA分布的理解可能是有用的。然而,还需要进一步研究血小板免疫学,以帮助制定血小板抗体引发的免疫疾病的最佳管理实践。

Background: Zinc depletion decreases monocyte functions and survival while excessive amount of zinc inhibits monocyte activation. Monocytes shift from conducting intercellular communication to becoming innate immune function as a response. This study aims to examine the influence of zinc status on the monocyte phagocytosis in patients with major beta-thalassemia. Materials and Methods: This study was a randomized-placebo-controlled trial. The patients were randomly assigned into either the zinc-treated group using zinc gluconate 50mg daily or the placebo group. Analysis is based on the 12-weeks observation of the complete blood count, plasma zinc level, and phagocytosis level of monocytes. The phagocytic activity of monocytes was measured using atomic absorption spectroscopy (AAS) or x-ray fluorescence (XRF). The comparisons of the data within each group were analyzed using Mann-Whitney test. Results: The results indicated no significant differences in patients’ characteristics; the level of plasma zinc at week 12 in the zinc-treated group (67.41+14.4) was significantly higher than the placebo group (54.37+9.38) (p=0.047). The phagocytosis levels of monocyte at week 12 in zinc-treated group (8.70+4.61) were higher than the placebo groups (8.23+4.22) (p=0.002). The ferritin level of zinc-treated group was higher than placebo group (p=0.084), while high level of ferritin is associated with higher level of monocyte phagocytic activity, the result is statistically significant (p=0.002). The results also showed that higher level of plasma zinc insignificantly correlates with lower phagocytic activity of the monocytes (p=0.059). Conclusion: The immune mechanisms in response to zinc-deficient environment underlying the shifting between adaptive to innate immune response involves multiple molecular components of the immune system and have been attributed to specific features of -thalassemia, in which overall immune activity is decreased even though the phagocytic activity of monocytes is increased.
背景:锌缺乏会降低单核细胞的功能和存活,而过量的锌会抑制单核细胞的激活。单核细胞从进行细胞间通讯转变为作为应答的先天免疫功能。本研究旨在探讨锌对重度-地中海贫血患者单核细胞吞噬功能的影响。材料与方法:本研究为随机安慰剂对照试验。患者被随机分配到每天50mg葡萄糖酸锌的锌治疗组和安慰剂组。分析基于12周的全血细胞计数、血浆锌水平和单核细胞吞噬水平的观察。采用原子吸收光谱(AAS)或x射线荧光(XRF)测定单核细胞的吞噬活性。各组数据比较采用Mann-Whitney检验。结果:结果显示两组患者的特征无显著差异;锌治疗组第12周血浆锌水平(67.41+14.4)显著高于安慰剂组(54.37+9.38)(p=0.047)。第12周,锌治疗组单核细胞吞噬水平(8.70+4.61)高于安慰剂组(8.23+4.22)(p=0.002)。锌治疗组铁蛋白水平高于安慰剂组(p=0.084),而高铁蛋白水平与较高的单核细胞吞噬活性相关,结果具有统计学意义(p=0.002)。血浆锌水平升高与单核细胞吞噬活性降低相关性不显著(p=0.059)。结论:锌缺乏环境下适应性免疫反应向先天免疫反应转变的免疫机制涉及免疫系统的多个分子成分,并归因于-地中海贫血的特定特征,在这种情况下,尽管单核细胞的吞噬活性增加,但总体免疫活性降低。

Background: Aberrant DNA methylation of the promoter region is one of the most epigenetic changes in numerous cancers. DNA methyltransferase inhibitors (DNMTIs) can revert DNA hypermethylation in tumor suppressor genes (TSGs). The present study was designed to investigate the effect of 5-fluoro-2′-deoxycytidine (FdCyd) on p16INK4a, p14ARF, p15INK4b, and DNA methyltransferase 1, 3a, and 3b genes expression, apoptosis induction, cell growth inhibition in pancreatic cancer AsPC-1 and hepatocellular carcinoma LCL-PI 11 cell lines. Materials and Methods: The cells were treated with FdCyd at different periods. Then, the MTT assay, cell apoptosis assay, and qRT-PCR were done to determine cell viability, cell apoptosis, and the relative gene expression level respectively. Results: The FdCyd decreased DNA methyltransferase 1, 3a, and 3b and increased p16INK4a, p14ARF, and p15INK4b genes expression significantly (P<0.001). Besides, LCL-PI 11 cell was more sensitive to FdCyd in comparison to AsPC-1 cell. FdCyd induced significant cell growth inhibition with a doseand time-dependent manner (P<0.001). The IC50 value of FdCyd was obtained with approximately 1μM. Further, FdCyd induced cell apoptosis significantly as a time-dependent manner. The number of apoptotic cells was significantly increased in all groups. The percentage of apoptotic cells after 24 and 48 h were 13.86 and 29.6 % in AsPC-1 and 21.04 and 41.52 % in LCL-PI 11 cell line respectively (P<0.001). Conclusion: The FdCyd can reactivate the p16INK4a, p14ARF, and p15INK4b through inhibition of DNA methyltransferase 1, 3a, and 3b gene expression.
背景:启动子区域的异常DNA甲基化是许多癌症中最常见的表观遗传变化之一。DNA甲基转移酶抑制剂(DNMTIs)可以恢复肿瘤抑制基因(TSGs)的DNA超甲基化。本研究旨在探讨5-氟-2′-脱氧胞苷(FdCyd)对胰腺癌AsPC-1和肝癌LCL-PI 11细胞株p16INK4a、p14ARF、p15INK4b和DNA甲基转移酶1、3a、3b基因表达、诱导凋亡、抑制细胞生长的影响。材料与方法:在不同时期用FdCyd处理细胞。然后分别采用MTT法、细胞凋亡法和qRT-PCR法检测细胞活力、细胞凋亡和相关基因表达水平。结果:FdCyd显著降低了DNA甲基转移酶1、3a、3b的表达,显著提高了p16INK4a、p14ARF、p15INK4b基因的表达(P<0.001)。此外,lc - pi 11细胞对FdCyd的敏感性高于AsPC-1细胞。FdCyd诱导显著的细胞生长抑制,且呈剂量和时间依赖性(P<0.001)。FdCyd的IC50值约为1μM。此外,FdCyd以时间依赖性的方式显著诱导细胞凋亡。各组细胞凋亡数量均显著增加。24h和48h后,AsPC-1细胞的凋亡率分别为13.86%和29.6%,cl - pi 11细胞的凋亡率分别为21.4%和41.52% (P<0.001)。结论:FdCyd可通过抑制DNA甲基转移酶1、3a、3b基因的表达,激活p16INK4a、p14ARF、p15INK4b。

DNA methyltransferase inhibitors (DNMTIs) can revert DNA hypermethylation in tumor suppressor genes (TSGs). The present study was designed to investigate the effect of 5-fluoro-2′-deoxycytidine (FdCyd) on p16INK4a, p14ARF, p15INK4b, and DNA methyltransferase 1, 3a, and 3b genes expression, apoptosis induction, cell growth inhibition in pancreatic cancer AsPC-1 and hepatocellular carcinoma LCL-PI 11 cell lines. Materials and Methods: The cells were treated with FdCyd at different periods. Then, the MTT assay, cell apoptosis assay, and qRT-PCR were done to determine cell viability, cell apoptosis, and the relative gene expression level respectively. Results: The FdCyd decreased DNA methyltransferase 1, 3a, and 3b and increased p16INK4a, p14ARF, and p15INK4b genes expression significantly (P<0.001). Besides, LCL-PI 11 cell was more sensitive to FdCyd in comparison to AsPC-1 cell. FdCyd induced significant cell growth inhibition with a doseand time-dependent manner (P<0.001). The IC50 value of FdCyd was obtained with approximately 1μM. Further, FdCyd induced cell apoptosis significantly as a time-dependent manner. The number of apoptotic cells was significantly increased in all groups. The percentage of apoptotic cells after 24 and 48 h were 13.86 and 29.6 % in AsPC-1 and 21.04 and 41.52 % in LCL-PI 11 cell line respectively (P<0.001).

Lymphoma which has a wide range of manifestations is the third malignancy in pediatrics. Nearly, 50% of patients have extranodal involvement. Pancreas can be affected secondarily more than primarily. A 10-year-old boy with recurrent abdominal pain in the epigastric region for six weeks was referred to Amirkola Children's Hospital, affiliated to Babol University of medical sciences (north of Iran). The patient was icteric with elevated levels of amylase and lipase. A hypoechoic mass near the head of the pancreas was detected by ultrasound examination. Pathology of stomach polyps revealed small blue round-cell tumor compatible with a lymphoma. In children with acute pancreatitis symptoms and palpable abdominal mass, the non-Hodgkin lymphomas (NHL) should be considered as an important, though rare possible cause.
淋巴瘤表现广泛,是儿科第三大恶性肿瘤。近50%的患者有结外受累。胰腺可继发性影响多于原发性影响。一名上腹部复发性腹痛6周的10岁男孩被转诊到Amirkola儿童医院,该医院隶属于巴博勒医科大学(伊朗北部)。患者黄疸,淀粉酶和脂肪酶水平升高。超声检查发现胰腺头部附近有一个低回声肿块。胃息肉病理显示小的蓝色圆细胞肿瘤与淋巴瘤相容。在有急性胰腺炎症状和可触及的腹部肿块的儿童中,非霍奇金淋巴瘤(NHL)应被认为是一个重要的,尽管罕见的可能原因。

Background: Iron extra load is an anticipated and lethal consequence of chronic blood transfusion in major beta-thalassemia patients; therefore it is necessary to use an efficient iron chelator drug to stimulate the evacuation of the surplus iron from the body. This trial was performed to compare myocardial and hepatic magnetic resonance imaging T2 (MRI T2*) results of beta-thalassemia patients treated by Deferasirox or combination of Deferoxamine and Deferiprone. Material and Methods: In this clinical trial, 44 patients who were on combination therapy with Deferiprone and Deferoxamine and complied with the inclusion criteria were randomized to either case (Deferasirox) or control (combined therapy) groups. Twenty-two patients in the case group received Deferasirox. For 22 patients in the control group, prior treatment with Deferiprone and Deferoxamine was continued. Myocardial and hepatic MRI T2* results were assessed before and after the study. Moreover, serum ferritin level (SFL) was evaluated every 3 months. Results: SFL at the start of the study did not differ significantly in two groups (2158.1± 1012.2 μg/L in the control group vs. 2145.5±1121.4 μg/L in the case group) (P=0.08). SFL at the end of the study did not differ significantly in two groups (2204.4±1143.5 μg/L in the control group vs. 2347.2±1236.6 μg/L in the case group), either (P=0.12). In each group, myocardial and hepatic MRI T2 at the start and at the end of the trial did not differ significantly (P>0.1). Conclusion: Myocardial and hepatic MRI T2*results were better in the control (combination therapy) group than those in the case (Deferasirox) group. Major beta-thalassemia patients replied to combined treatment better than Deferasirox.
背景:铁额外负荷是主要β地中海贫血患者长期输血的预期和致命后果;因此,有必要使用有效的铁螯合剂药物来刺激多余的铁从体内排出。本试验旨在比较接受去甲罗克斯或去甲罗胺和去甲酮联合治疗的β地中海贫血患者的心肌和肝脏磁共振成像T2(MRI T2*)结果。材料和方法:在本临床试验中,44名接受去铁酮和去铁胺联合治疗并符合纳入标准的患者被随机分为病例组(去铁罗克斯)或对照组(联合治疗)。病例组中有22名患者接受了去甲罗司。对照组中的22名患者继续先前的去铁酮和去铁胺治疗。在研究前后评估心肌和肝脏MRI T2*结果。此外,每3个月对血清铁蛋白水平(SFL)进行一次评估。结果:两组在研究开始时的SFL没有显著差异(对照组2158.1±1012.2μg/L与病例组2145.5±1121.4μg/L)(P=0.08)。研究结束时,两组的SFL也没有显著差异,对照组为2204.4±1143.5μg/L,病例组为2347.2±1236.6μg/L(P=0.012),心肌和肝脏MRI T2 结论:对照组(联合治疗)的心肌和肝脏MRI T2*结果优于病例组(去甲罗司)。主要β地中海贫血患者对联合治疗的反应好于去甲罗司。

Background: Acute kidney injury (AKI) is defined as a failure in renal function leading to insufficiency of fluid and electrolyte homeostasis. Thus, sensitive biomarkers of renal tubular injury are needed to detect AKI earlier. In this study, urinary beta 2-microglobulin (β2-MG) and urinary N-acetyl-β-D-glucosaminidase (NAG) were evaluated for AKI prognosis/diagnosis in pediatric patients suffering different cancers prescribed with Ifosfamide, Ifosfamide plus Carboplatin, and Ifosfamide plus Cisplatin. Materials and Methods: In this prospective study done in Isfahan, Iran, urinary β2-MG, urinary NAG, blood urea nitrogen (BUN), and serum and urinary creatinine (Cr) were measured in 40 pediatric cancer patients less than 16 years old in three age groups during 61 courses of chemotherapy on day 0, three and six after the treatment. Results: Using ANOVA and t-test, the mean levels of urinary β2-MG (p= 0.001), urinary β2-MG/Cr (p= 0.003) and urinary NAG/Cr (p= 0.001), before and on day six of the treatment were statistically significant (p< 0.05). Also, the mean levels of BUN (p= 0.01), urinary β2-MG (p= 0.001), β2-MG/Cr (p= 0.001) and NAG/Cr (p= 0.004) based on the gender groups, the mean levels of urinary NAG (p=0.001), NAG/Cr (p= 0.001) and β2-MG/Cr (p= 0.008) based on three age groups, and the mean levels of serum Cr (p= 0.047), urinary β2-MG (p= 0.005), β2-MG/Cr (p= 0.032) and NAG/Cr (p= 0.032) based on the Ifosfamide dosage were statistically significant during the time of the treatment. Conclusion: Urinary β2-MG, urinary β2-MG/Cr, and urinary NAG/Cr are more significant biomarkers than serum Cr in earlier diagnosis and treatment of AKI in cancer patients. However, urinary NAG should be further studied to prove its reliability for AKI prognosis/diagnosis. It is suggested that urinary NAG can be used along with other renal biomarkers such as urinary β2-MG, kidney injury molecule-1(KIM-1), or interleukin-18 (IL-18) for AKI prognosis/diagnosis.
背景:急性肾损伤(AKI)被定义为肾功能衰竭,导致液体和电解质稳态不足。因此,需要肾小管损伤的敏感生物标志物来更早地检测AKI。在这项研究中,对患有不同癌症的儿童患者的AKI预后/诊断进行了评估,这些患者使用了Ifosfamide、Ifosfamile加卡铂和Ifosfamide加顺铂。材料与方法:在伊朗伊斯法罕进行的这项前瞻性研究中,在治疗后第0天、第3天和第6天,对3个年龄组40名16岁以下癌症儿童患者进行了61个疗程的尿β2-MG、尿NAG、血尿素氮(BUN)、血清和尿肌酐(Cr)的测量。结果:应用方差分析和t检验,治疗前和治疗第6天尿β2-MG(p=0.001)、尿β2-MG/Cr(p=0.003)和尿NAG/Cr(p=0.001,基于三个年龄组的NAG/Cr(p=0.001)和β2-MG/Cr(p=0.008),在治疗期间,基于Ifosfamide剂量的血清Cr(p=0.047)、尿β2-MG(p=0.005)、β2-MG/Cr(p=0.032)和NAG/Cr的平均水平具有统计学意义。结论:在癌症患者AKI的早期诊断和治疗中,尿β2-MG、尿β2-MG/Cr和尿NAG/Cr是比血清Cr更重要的生物标志物。然而,尿NAG应进一步研究,以证明其对AKI预后/诊断的可靠性。提示尿NAG可与其他肾脏生物标志物如尿β2-MG、肾损伤分子-1(KIM-1)或白细胞介素-18(IL-18)一起用于AKI的预后/诊断。

Background: Due to the increase in cancer and side effects of common therapies, researchers are looking for treatments with the least side effects, which is why medicinal plants have become so important. Adiantum capillus-veneris L. plant commonly called southern maidenhair fern, and also named as “Pare-siavashan” in medical and pharmaceutical textbooks of Iranian Traditional Medicine, contains triterpenoid compounds that have anti-tumor properties. It is a perennial fern with narrow stems and small leaves that grows in hot and humid places. This study aims to make biocompatible nanosystems carrying Adiantum capillus-veneris extract with an appropriate loading rate and to compare the anti-tumor properties of the extract-carrying system with its free state. Materials and Methods: After Extracting by Soxhlet, the resulting extract was loaded in the nano-niosome system by thin-film method and was subjected to physical, chemical, and cellular characterization. Results: The results of this study showed that the loading rate of Adiantum capillus-veneris extract in niosomic formulation is 50.74% and the resulting particles are spherical with a size of 325.7nm and anionic. No chemical interactions were found between niosome and extract and the resulting system was chemically stable. Conclusion: Based on acquired results, the designed system has acceptable anti-cancer properties on MCF7 cell line. It is notable that the cell survival rate was about 19 %.
背景:由于癌症和常见疗法副作用的增加,研究人员正在寻找副作用最小的治疗方法,这就是药用植物变得如此重要的原因。铁线蕨(Adiantum capillus veneris L.)是一种植物,通常被称为南方maidenhair fern,在伊朗传统医学的医学和药学教科书中也被称为“Pare siavashan”,含有具有抗肿瘤特性的三萜化合物。它是一种多年生蕨类植物,茎细叶小,生长在炎热潮湿的地方。本研究旨在制备具有适当负载率的生物相容性纳米系统,并将提取物负载系统的抗肿瘤性能与其游离状态进行比较。材料和方法:经索氏提取后,将所得提取物通过薄膜法负载于纳米niosome系统中,并进行物理、化学和细胞表征。结果:本研究结果表明,铁线蕨提取物在niosomic配方中的负载率为50.74%,所得颗粒为球形,粒径为325.7nm,为阴离子颗粒。在niosome和提取物之间没有发现化学相互作用,所得体系化学稳定。结论:基于所获得的结果,所设计的系统对MCF7细胞系具有可接受的抗癌性能。值得注意的是,细胞存活率约为19%。
