BACKGROUND Cryptosporidium parvum causes severe gastroenteritis in immunocompromised human and new borne animals. The organism can be transmitted through water. Since small number of C. parvum is infectious, the aim of the present study was to develop a chromatography method for the isolation of C. parvum oocyst in samples with limited number of oocysts. METHODS Antibody was prepared against ...

Cell envelopes of Salmonella typhimurium and Escherichia coli were disrupted in a French pressure cell and fractionated by successive cycles of sedimentation and floatation density gradient centrifugation. This permitted the identification and isolation of several membrane fractions in addition to the major inner membrane and murein-outer membrane fractions. One of these fractions (fraction oML...

A composite gastro-retentive matrix for zero-order delivery of highly soluble drug alfuzosin hydrochloride (10mg) has been designed and characterized. Two systems containing polyethylene oxide (PEO), hydroxypropylmethylcellulose (HPMC), sodium bicarbonate, citric acid and polyvinyl pyrrolidone were dry blended and compressed into triple layer and bi-layer composite matrices. Dissolution studies...
