The virucidal effect of pH and salinity on Penaeus monodon baculovirus (MBV) was investigated by water borne inoculated methods exposing PL12 Penaeus semisulcatus for 10 hours and observing for 10 days at temperature 28- 30°C. For this purpose, one thousand virus free PL12 of P. semisulcatus were divided into five groups and each group placed in a 10 L plastic basin containing chlorine-treated ...

The myocardial effect of snake venoms is considered as one of the most common pathogenesis in many cases of snake envenomation. This study was under taken to investigate the effects of snake (Naja naja oxiana) venom on cardiac function in experimental animals. The blood samples from all the rabbits were collected before venom injection and then 140 µg/kg venom of snake (Naja naja oxiana) was in...

BACKGROUND AND PURPOSE We sought to investigate the impact of hyperglycemia before reperfusion on long-term outcome in patients treated with intravenous tissue plasminogen activator (tPA). METHODS Of 268 consecutive patients with a nonlacunar middle cerebral artery (MCA) stroke evaluated at <3 hours after onset, 73 (27.2%) received intravenous tPA. Serum glucose was determined at baseline bef...
