Incomplete laboratory request forms as a contributory factor to preanalytical errors in a Nigerian teaching hospital

That most laboratory errors occur in the preanalytical phase has been demonstrated in the past. There is paucity of data on the contribution of incomplete request forms to preanalytical errors in Nigerian hospitals. We examined our laboratory request forms for the frequency of incomplete data. Request forms received at the laboratory in a three- month period were examined for some parameters. The completeness of...

Activities of some enzymes, enzyme inhibitors and antinutritional factors from the seeds of sponge gourd (Luffa aegyptiaca M.)

Activities of some of the enzymes; enzyme inhibitors and antinutritional factors of the seeds ofLuffa aegyptiaca were investigated. Enzymes were extracted and their activities determined using standard procedures. The activities of trypsin and amylase inhibitors were also determined using standard procedures. While antinutritional factors were detemined using the AOAC method as well as standard procedures. The...

Extraction and application of dye extracted from eriophyid leaf galls of Quercus leucotrichophora-A Himalayan bluejack oak

Oaks (Quercus sp.) are susceptible to a wide diversity of gall-forming insects. When the insect pupates and leaves, the gall can be used as a dyestuff. Kalamkari unit’s method (India) was followed for the extraction of dye. A dark brown dye was obtained from the leaf gall of Quercus leucotrichophora caused by Eriophyes sp. Three different types of cloths and three different types of yarns...

Characterization of the polysaccharide material that is isolated from the fruit of Cordia abyssinica

Treatment of aqueous extracts of the fruit of Cordia abyssinica, containing 0.25% sodium chloride with three volumes of ethanol produced an acidic polysaccharide with a 2% yield, on a fresh weight basis. Upon precipitation of the polysaccharide with acid, the yield of the polysaccharide decreased to 1.2% and the polymer showed some level of degradation. With protein content between 2.6 and 4.6% for the acid and...

Trace metals and oxidative metabolic changes in malignant prostate cancer patients

Metabolic derangement commonly associated with prostate cancer (PCa) has not been well researched in Nigerian malignant PCa patients yet. The present study was designed to assess the levels of selected trace metals (Zn, Cu, Cr, Fe, Co, and Se) and markers of oxidative stress,such as total plasma peroxide (TPP), total antioxidant potential (TAP), oxidative stress index (OSI) and free malondialdehyde...
