Endonasal endoscopic laser-assisted dacryocystorhinostomy has many advantages over conventional external dacryocystorhinostomy. This technique avoids a cutaneous scar and causes less surgical trauma and bleeding than that seen in conventional lacrimal surgery. A total of 20 endoscopic laser-assisted dacryocystorhinostomy in 16 patients were performed between 1998 and 1999. The procedure was suc...

In infants with neurofibromatosis type 1, plexiform neurofibroma with altering anterior segment outflow system may result in raised intraocular pressure. Here we report a case of buphthalmos with neurofibromatosis (NF-1) who suffered with blindness suffered enucleation. Physical examination and histopathology were performed. Physical examination revealed Buphthalmos and vascularized cornea with...

Reports which describe sick sinus syndrome due to malignant lymphoma have been rare and only eight cases have been reported until now. This is a case of sick sinus syndrome and superior vena cava syndrome secondary to invasion of occult malignant lymphoma of the lung in a 60 years old male.

Glutathione S-transferases (GSTs) are widespread in Fasciola. hepatica parasite and sheep liver tissue. Study of GSTs inhibition assays in F. hepatica and sheep liver tissue are a priority of chemotherapeutic targets in parasitic liver diseases including human fascioliasis in Iran. In this research, the whole extract of F. hepatica and sheep liver tissues were purified and eluted for sodium dod...

A rust fungus was found causing stem cankers on 1to 5-year-old stems of Salix elbursensis in the north west of Iran. The rust also forms uredinia on leaves and flowers of the host willow. Light and scanning electron microscopy revealed that the new rust is morphologically distinct from several Melampsora species occurring on the willows taxonomically close to S. elbursensis, but indistinguishab...

In this study, we investigated the chromosome numbers of some endemic species distributed in East and South-East Iran. The mitotic chromosome counts were presented for the first time for six species in three angiosperm families including: Linaria iranica (2n=12), Nanorrhinum campyloceras (2n=18), Chaenorhinum grossecostatum (2n=24) (Plantaginaceae), Gaillonia bruguieri (Rubiaceae) (2n=22), Nepe...
