伊朗传统医学治疗牙周疾病

目的:牙周疾病非常普遍,尽管有各种特定的治疗方法,但我们始终面临治疗方法有限的问题。考虑到世界组织十分关注传统医学在医疗服务中的发展和应用,我们在一直考察研究伊朗传统医学中药物对牙周疾病的治疗作用。方法:此项研究是一个对有关方面书籍的综合论述,伊朗传统医学内容是经过对重量级作者如Avicenna和Alzahrawy所著的有价值的书籍修订,收集了各医学院校馆藏图书和医药公司的有关信息编辑而成,因为在伊朗传统医学中牙周疾病分成不同目类,对有关药物的研究也被分成8个大组63个题目。(1)缓解牙龈肿胀药物(2)治疗牙龈恶化药物(3)治疗口疮腐烂药物(4)治疗牙龈肥大药物(5)利于伤口康复药物(6)利于牙龈加固的药物(7)阻止牙龈出血的药物(8)防止牙齿松动药物。结果结论:伊朗传统医学在准确的观察和实践的基础上来描述和治疗牙周疾病的。在制药学、有效治疗方面、科学研究手段等领域,伊朗传统医学在以下几个方面可作为现代制药研究的重要资源:(1)纯天然资源(2)容易获得(3)相对比较安全。     

Atypical Presentation of Hashimoto’s Disease in an Adolescent: Thyroid-Associated Ophthalmopathy

Hashitoxicosis is generally differentiated from Graves’ hyperthyroidism by its shorter course and absence of ophthalmopathy. In this case report, we describe an adolescent girl who presented with significant clinical findings of hyperthyroidism, a diffuse goiter with homogenously increased uptake in scintigraphy, and with ocular findings of ophthalmopathy. The thyroid stimulating hormone receptor antibody test was positive, and the family history revealed thyroid-associated ophthalmopathy. Clinical findings supported the diagnosis of Hashimoto’s disease (HD) in the follow-up period. Radioactive iodine uptake investigation was found to be a reliable method for differential diagnosis. Attention was drawn to the rarity of pediatric cases of HD who present with ophthalmopathy.     

Case report of a patient with osteopoikilosis

Osteopoikilosis (OPK) is an uncommon osteosclerotic dysplasia. There is no exact evidence of its etiology and pathogenesis. Usually, it is an asymptomatic disease, and the diagnosis is made incidentally from radiographs, which show multiple, small, well-defined, variably shaped and widely distributed sclerotic areas over the skeleton. In this study, we report a 54-year-old man who suffers from back and leg pain and was diagnosed OPK by radiologically and review literature.     

Classification of carotid artery Doppler signals in the early phase of atherosclerosis using complex-valued artificial neural network

In this study, carotid arterial Doppler ultrasound signals were acquired from left carotid arteries of 38 patients and 40 healthy volunteers. The patient group had an established diagnosis of the early phase of atherosclerosis through coronary or aortofemoropopliteal angiographies. Results were classified using complex-valued artificial neural network (CVANN). Principal component analysis (PCA) and fuzzy c-means clustering (FCM) algorithm were used to make a CVANN system more effective. For this aim, before classifying with CVANN, PCA method was used for feature extraction in PCA-CVANN architecture and FCM algorithm was used for data set reduction in FCM-CVANN architecture. Training and test data were selected randomly using 10-fold cross validation. PCA-CVANN and FCM-CVANN architectures classified healthy and unhealthy subjects for training and test data with about 100% correct classification rate. These results shown that PCA-CVANN and FCM-CVANN classified Doppler signals successfully.     

Some arylacridine derivatives possessing potassium channel opening activity

In this study, six new 2,2,7,7-tetramethyl-9-aryl-2,3,4,5,6,7,9,10-octahydro-1,8-acridinedione derivatives (1-6) were synthesised and their functional effects on vascular potassium channels and mechanism of induced relaxations on phenylephrine-induced contractile responses in isolated rat mesenteric arteries were investigated. Pinacidil was used as standard potassium channel opener. Compounds 1, 2, 5, 6 and pinacidil induced concentration-dependent relaxation response of vessel rings previously contracted with phenylephrine.     

Apelin/APJ expression in the heart and kidneys of hypertensive rats

Hypertension is an important health problem that is manifested by systemic arterial blood pressure being permanently elevated and leading to serious complications. Hypertension is the basis for coronary heart diseases, heart failure, kidney damage, cerebrovascular diseases. Due to ethical concerns, there is no detailed study of the mechanism, side effects and treatment of hypertension in humans. For this reason, specific studies related to the organ of hypertension are performed in experimental animals. The heart and kidney tissue, which are the most important organs that hypertension has damaged, have formed specific organs of our work.In our experimental study, a total of 35 (hypertensive group: 20, control group: 15) Rattus Norvegicus Wistar albino rats were used. In order to obtain our hypertension model, our experimental animals were given L-NAME together with drinking water for six weeks. After six weeks, the experimental procedures were terminated. Heart and kidney tissues of the hypertensive and control group were obtained. Expression of apelin and apelin receptor (APJ) was demonstrated by immunohistochemical and Western Blot protocols.Hypertrophic cardiac atrium of the hearts of the large cavities, interventricular septum and myocardium to the disintegration, as well as an increase in the diameter of the coronary artery has been observed. In general, kidney tissues of the hypertensive group showed narrowing in cortical renal structures and enlargement in structures in the renal medulla.As a result, in hypertensive cases, there was an increase in expression of Apelin and APJ receptor in heart tissue, and a decrease in expression of Apelin and APJ receptor in kidney tissue. We think that our findings may contribute to experimental or clinical studies related to hypertension and apelin.     

Complications of radical vulvectomy and inguinal lymphadenectomy for the treatment of carcinoma of the vulva.

Forty-two patients with invasive carcinoma of the vulva, subjected to radical vulvectomy and inguinal lymphadenectomy, were evaluated retrospectively. The mean age of patients was 61.6 years. Fifteen patients (35.7%) had complicating medical diseases, the histopathological diagnoses were squamous carcinoma (n = 39), undifferentiated carcinoma (n = 1), and malignant melanoma (n = 2). The postoperative morbidity and mortality rates were found to be 73.8% and 11.6%, respectively.
