In order to survey on sparrows parasites （Passer domesticus）, 100 samples were collected from the citrus gardens of Amol＇s City. The surface of their body checked for presence of ectoparasites. The blood samples took from their wings for blood parasites. At the laboratory, the body of sparrows opened and the gastrointestinal checked for endoparasites. The intestine opened and scratched carefully to find worms. Worms kept in alcohol-glycerin （10%）. Eggs ＆ oocysts of the parasites checked, by fecal floatation test. The result shows that the infection with Railletina is 1%, Ascaridia galli （2%）, Heterakis gallinarum （4%）, eggs of A. galli （5%）, oocyst of Eimeri （28%）, Dermanyssus gallinae （1%）. 11% of the sparrows infected with Plasmodium in their bloods.

Objective To evaluate the effect of electrical stimulation of dorsal raphe nucleus（DRN）on response properties of layer IV barrel cortex neurons following long-term sensory *** Male Wistar rats were divided into sensory-deprived（SD）and control（unplucked）*** SD group,all vibrissae except the D2 vibrissa were plucked on postnatal day one,and kept plucked for a period of 60 *** that,whisker regrowth was allowed for 8-10 *** D2 principal whisker（PW） and the D1 adjacent whisker（AW）were either deflected singly or both deflected in a serial order that the AW was deflected 20 ms before PW deflection for assessing lateral inhibition,and neuronal responses were recorded from layer IV of the D2 barrel *** was electrically stimulated at inter-stimulus intervals（ISIs）ranging from 0 to 800 ms before whisker *** PW-evoked responses increased in the SD group with DRN electrical stimulation at ISIs of 50 ms and 100 ms,whereas AW-evoked responses increased at ISI of 800 ms in both *** plucking before DRN stimulation could enhance the responsiveness of barrel cortex neurons to PW deflection and decrease the responsiveness to AW deflection. DRN electrical stimulation significantly reduced this difference only in PW-evoked responses between ***,no DRN stimulation-related changes in response latency were observed following PW or AW deflection in either ***, condition test（CT）ratio increased in SD rats,while DRN stimulation did not affect the CT ratio in either *** was no obvious change in 5-HT2A receptor protein density in barrel cortex between SD and control *** These results suggest that DRN electrical stimulation can modulate information processing in the SD barrel cortex.
