Abstract

This investigation is a collection of studies on the breeding birds of Dez Protected Area performed from Fe-bruary 2011 to Jun 2012. During that period, field studies were executed every other 2-4 days. 5 species of native bree-ding birds including White-eared Bulbul Pycnonotus leucotis, Common Babbler Turdoides caudatus, Collared Dove St-reptopelia decaocto, Laughing Dove Streptopelia senegalensis, European Roller Coracias garrulous and 7 species of migratory breeding birds including Grey Hypocolius Hypocolius ampelinus, Great Grey Shrike Lanius excubitor, Little Ringed Plover Charadrius dubius, Red-wattled Lapwing Vanellus indicus, Pin-tailed Sandgrouse Pterocles alchata Ba-nk Swallow Riparia riparia, Blue cheeked Bea-eater Merops persicus were observed. Among the breeding birds, Coll-ared Dove S.decaocto had the most extensive breeding period from February till the early of August. Common Babbler T. caudatus (53 nests) was the frequent breeder in the terrestrial part of the Dez Protected area. Terrestrial breeding bi-rds of the area prefer habitats with Ziziphus nummularia, vegetations for breeding. Bank Swallow R.riparia with more than 300 nests was the most common species in the watery part of Dez Protected Area. They selected riparian walls for nest building. Habitat destruction was the most important threatening factor for the breeding birds.

Abstract

The study attempts to evaluate the effects of silver nanoparticles on preventing the destruction of ovarian tissue in mice treated with isoniazid. In this experiment, 40 adult female rats were randomly divided into 5 groups (n=8) including: control group (no treatment), sham group (0.2 mg / kg normal saline), experimental group 1 (50mg / kg Ison-iazid), experimental group 2 (50mg / kg Isoniazid and 0.25mg/kg silver nanoparticles) and the experimental group 3 (50mg / kg isoniazid and 0.50mg / kg silver nanoparticles). All injections were prescribed for 15 days and Isoniazid and silver nano-particles were received orally and intraperitoneally, respectively. All the animals were operated on and their ovarian tissues were removed and placed in 10% formalin solution. Then H & E staining was performed for histological studies. In experimental groups 1, 2 and 3, reduction in the number of secondary follicles and corpus luteum was obse-rved in comparison with the control group. There was a significant increase in the number of primordial and graafian follicles in experimental group 3 when it was compared with isoniazid group. In addition, a significant increase was observed in the number of primary monolayer follicles in experimental groups 2 and 3 in comparison with the experi-mental group 1. It should be assumed that by the utilization of the minimum dose of the silver nanoparticles, its toxic effects on the ovarian tissue could be ignored. Therefore, the minimum dose of the silver nanoparticles can reduce the isoniazid effects on ovarian tissue.
