Convenience of the traversal beam test modified to evaluate the model of Parkinson’s disease in rat lesioned in SNPC
The nigrostriatal degeneration underlying Parkinson’s disease is commonly studied in experimental animals by injection of the neurotoxin 6-hydroxydopamine (6-OHDA). The present study describes a modified version of a beam traversal test which allows the quantification of the motor deficit through the time spent to arrive to the platform once all four paws of the animals are in contact with the beam (escape...

Reassessment of endemicity level of Urinary Schistosomiasis in the Kotto-Barombi focus (South West Cameroon) and impact of mass drug administration (MDA) on the parasitic indices
The level of infestation and mechanism of persistence of urinary schistosomiasis was determined in two villages (Kotto Barombi and Marumba II) by conducting a survey on school children from May 2007 to May 2008. Urine samples were collected from 418 children and examined using filtration technique. All participants were subsequently treated by Praziquantel. Drug efficacy and incidence rate were assessed 3 months and 1...

Anticestodal activity and toxicity of some Praziquantel analogues
Four hundred - 21 days old male Bovans type chicks in 10 groups were infected with Raillietina tetragona cystcercoids. 6 groups treated with the N-alkyl/COOR derivatives of the open lactam form of praziquantel (PZQ ) in oral dose of 20 mg/kg body weight on day 21 and on day 24 post infection. The open lactam form compounds showed an efficacy of 40, 100, 100, 100, 74 and 56% on the first dose and an efficacy of...
