Suitability of the leaf extract of Jatropha gossypifolia as an anticoagulant for biochemical and haematological analyses
The extract of Jatropha gossypifolia leaf was obtained by crushing the leaf in a mortal and the fluid expressed out. The suitability of the leaf extract as an anticoagulant for biochemical and haematological analyses was determined. The anticoagulant effect of the extract was found to be highest at a concentration of 0.1 ml per ml of blood. Blood tubes with dried leaf extract at the stated concentration were used for obtaining plasma. Mean plasma glucose values obtained from fluoride oxalate plasma were compared with values obtained from dried leaf extract plasma. The values obtained for biochemical parameters with the exception of bicarbonate from the leaf extract plasma samples were significantly higher (
Extracts of Pterocarpus osun as a histological stain for collagen fibres
The staining ability of Pterocarpus osun extract on tissue sections was determined. 2 kg of P. osun stem was dried, milled to obtain a fine powder and a red pigment extracted from the powder with 1 L of 70% ethanol at 78°C for 24 h. The alcoholic and acidic extracts were used to stain tissue sections. Collagen fibres, red blood cells and muscles were stained in shades of reddish brown. Preliminary phytochemical screening of this extract revealed that it contained alkaloids, steroid ring, cardiac glycosides and reducing sugar.African Journal of Biotechnology Vol. 4 (5), pp. 460-462, 200
Full Length Research Article - Prevalence and Pattern of Lupus Erythematosus Cell Positivity in Diseases in Ile-Ife, Nigeria
The prevalence and pattern of lupus erythematosus (LE) cell positivity
in diseases in Ile-Ife, Osun state was carried out between January 1999
and June 2004 (5 1/2 years). A total of 96 patients with different
diseases were screened for LE cell using standard techniques. Of this
number, 63 (65.6%) were females and 33 (34.4%) were males, their age
ranges between 2 and 65 years (x 26.5 years). Twelve (12.5%) were
positive for LE cell within the period. Forty five (46.9%) were
screened between January 1999 and December 2002 (4 years), 4 (4.2%)
were positive for LE cell. Fifty one (53.1%) were screened between
January 2003 and June 2004 (11/2 years), 8 (8.3%) were positive for LE
cell. It was observed from the study that the LE cell positivity is on
the increase due to increase number of requests especially from renal
patients. LE cell positivity is also greater in females 7 (7.3%) than
in males 5(5.2%) and occurs more in the second and third decades of
life
