background: to achieve multiple oocytes for in vitro fertilization, ovulation induction is induced by gonadotropins however, it has several effects on oocytes and embryo quality and endometrium receptivity. the aim of this study was to assess ultrastructural changes of corpus luteum after ovarian induction using human menopausal gonadotropin (hmg) and human chorionic gonadotropin (hcg) during l...

abstract background tumor lysis syndrome (tls) is an oncologic emergency that results from massive lysis of malignant cells. the incidence of tls depends on the risk factors, such as baseline hyperuricemia, bulky tumor burden, elevated serum ldh, and elevated wbc. the objectives of the present study were to assess frequency of tumor lysis syndrom in children with all in two methods of induction...

fars province is one of the natural habitats of pyrus species in iran. harvesting of fruits, deforestation, expansion of agriculture and overgrazing in recent years has threatened the wild pear open forests and imposed detrimental effects on their natural regeneration, therefore, investigation on propagation of wild pear species for afforestation is needed. this research was carried out to deve...

the purpose of this study was to induce abomasal displacement to the left, and to let the undergraduate and post graduate students get used to the ping sounds of abomasum and other clinical manifestations. the procedure was carried out on eight young bulls, they were sedated and a 2 m flexible tube was inserted through the nasal canal into the rumen. by laparo-rumenotomy, 20 cm of the tube was ...

in a cross section of the patients scheduled for various operations, the plausability of lidocaine as an induction agent is studied and described. the results were dismaying suggesting, henceforth, that as an induction agent, lidocaine altogether fails to accomplish the assignment assigned to this drug.
