| دى شوية أسئلة فى البارا و اجاباتها اهى طريقة نسهل بيها مزاكرة البارا و نثبتها فى النافوخ [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة] [size=16]Questions and answers
1-give reason:-in fasciola,diagnosis by stool
examination is repeated.[/size][size=16]-to differentiate between true & false fasciolasis.
2-in fasciola,seriological test is more useful. -to detect true & false fascioliasis. -in early stage,there is no eggs to detect. -avoid intermittent absence of eggs in stool.
3-give reason:-water from rever is preserved for 48 hours. -because cercaria die after this time.
4-give reason:-there is malignancy in urinary bladder not in colon in schistosoma. -as eggs secrete B glucuronidase+tryptophan from urine=carcinogenic ulcer.
5-give reason:-seriological test is more important for diagnosis of schistosoma. -detect early infection. -detect late infection. -detect ectopic infection.
6-give reason:-Control of schistosoma haematobium is easer than mansoni. -Because,there is no reservoir host in schistosoma haematobium but present in mansoni.
7-Differentiate bet. Miracidium,Coracidium.
Coracidium:ciliated hexacanthembryo
Miracidium: ciliatedbody

[size=16]8-inf. stage ofcycticercosis eggs of taenia solium.[/size][size=16]9-parasite affecting eye cysticercous cellulosae
10-parasite causing muscle pain,eosinophilia cysticercous cellulosae. 11-parsite causing diarrhea &colics taenia solium 12-give reason:taenia solium is more dangerous than taenia soginata? -because it may cause autoinfection by its eggs,leading to cystecercosis that cause clinical manifestation to brain and heart. Whil taenia saginata eggs dont hatch in small intestine of man.
13-factors affecting cysticercosis 1-allergic reaction(+ve/-ve). 2-viability of larva causing reaction. 3-organ affected. 4-numbers of larva.
14-Differentiate between unilocular – multilocular –oessus hydatid cyst??? انظر الكتاب (هو كله بالساهل ولا ايه[ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة])
15-give reason:-Niclosamide is given 5 days in treatment of H.NaNa. -as Niclosamide not absorbed cant kill larva -full dose(1day to kill adult). -half dose(5days to kill larva when formed to adult).
16-Mention methods of infection of H.NaNa. -direct,from man to man. -contaminated food. -autoinfection(external,internal).
17- Mention mode of infection of H.Diminuta to man. -when eating adult rat flea,while it get infected when it was larva.
18- Mention mode of infection D.Caninum to man. -when eating adult dog flea during closed contact with dog(playing)
19-Mention diseases caused by closed contact to dogs. -coneureus cerebralis cyst. -hydatid disease. -D.caninum.
20-Mention parasite common in children. - D.caninum. -H.NaNa
21-Tissue cystodes??? -def.:-cystode worms in tissue of man -examples:-sparaganosis -cystecercosis -coneureus cerbralis cyst -hydatid disease -cysticercoid of H.NaNa
22-Mention role of cats-dogs in transmission of cystodes: -direct,through stools:coneureus cerebralis cyst/hydatid disease/d.caninum. -indirect:diph.manson(sparaganosis). [/size] | |
