purpose: to compare thickness of central cornea measured using pentacam, orbscan ii, and ultrasound pachymeter methods: patients with no history of corneal diseases or systemic diseases affecting eyes, who did not wear contact lens or use eye medications, and who with no previous history of corneal surgery were selected for this study. central corneal thickness (cct) was measured by three metho...

introduction: phonophoresis is the use of ultrasound to enhancing cellular drug delivery through the skin. in this study the effect of clobethasole and hydrocortisone ointments phonophoresis on pain, knee osteoarthritis and some other symptoms was studied. methods: an experimental single blind randomized clinical trial (rct) was used. an available sampling technique was used for selection of pa...

dermatofibrosarcoma protuberans is an uncommon malignant mesenchymal tumor of the dermis, which most commonly appears on the body and extremities. a preoperative diagnosis of dermatofibrosarcoma protuberans is extremely difficult, because it is a very rare entity and its appearance is often similar to that of benign breast lesion. here, we presented a case of breast dermatofibrosarcoma protuber...

hydatid cyst (hc) is a parasitic disease that may involve many organs, especially the lung and the liver. pulmonary artery location of the hydatid cyst is extremely rare, but it may cause life-threatening complications. we report a case of a hydatid cyst that completely filled the left main pulmonary artery and its distal part without cardiac involvement. thoracic computed tomography showed fil...

annular pancreas is a rare congenital condition of the pancreas where the pancreatic tissue either partially or completely covers the duodenum by forming a ring. endoscopic ultrasound is rarely considered as the first diagnosis tool for annular pancreas. we here present a 48 years old man who was primarily provisionally diagnosed with pancreatic mass and was planned for pancreatoduodenectomy. b...

instruction: measurement of brachial artery diameter variation by ultrasound methods has commonly been used to test the endothelial function. it is known that the artery diameter is increased by flow stimulation. therefore in the present study, the effect of external obstruction, as flow stimulation, on the radial strain of the brachial artery was assessed. also the biomechanical behavior of th...

we have already shown that low intensity pulsed ultrasonic treatment increases rabbit radial fracture healing. the present experiment was undertaken to find out the best duration for treatment. a complete transverse fracture was made in the right radial bones of21 adult male rabbits by a stanley knife. the animals were divided into 4 groups: group 1, control groups 2, 3, and 4, experimental gro...

restrictions on the use of synthetic antioxidant such as butylated  hydroxyanisole  (bha) and butylated  hydroxytoluene (bht) are being imposed  because of  their carcinogecity. in this investigation  optimization  of phenolic extraction  process  frome  methanolic (80%)  extract (v/v) of  elaegnus  angustifolia  through  response  surface methodology  by fulin cio- calteu is  performrd  for op...

objective: in order to overcome the limitation of systemic administration of methylene blue, this study investigated the encapsulation of methylene blue in polymeric liposomes and drug release following sonication. methods: we encapsulated methylene blue into nanoliposomes. the dynamic light scattering (dls) method was used to measure the size distribution of the liposomes. after loading methyl...

background: ovarian immature teratoma is a very rare type of tumor associated with a high relapse rate and mortality. correspondingly, early diagnosis is important for effective treatment. the goal of this study was to retrospectively analyze the ultrasound characteristics of 11 cases of immature teratomas. materials and methods: between january 2002 and december 2010, 11 patients were diagnose...
