Salivary amino acids quantification using RP-HPLC during normal menstrual cycle
The present study was carried out to detect amino acids profile in women saliva in order to establish the qualitative and quantitative differences that might have potential value in detection of ovulation by noninvasive methods. For the collection of sample, the stages of menstrual cycle were decided by the physical and morphological examination of salivary fern pattern. The saliva from various reproductive...

Effects of ivermectin and albendazole on some liver and kidney function indices in rats
Evaluation of repeated administration of ivermectin and albendazole separately and in combination on some hepatic and renal function indices were examined in albino rats (Rattus novergicus). The experimental animals were randomly divided into four groups: those administered distilled water (control), those administered 0.4 mg/kg bodyweight of ivermectin (Iver), those administered 15 mg/kg body weight...

Effect of 3-hydroxymethyl xylitol on hepatic and renal functional markers and protein levels in streptozotocin-diabetic rats
Oral administration of 3-hydroxymethyl xylitol at 40 mg/kg body weight to diabetic rats for 45 days resulted in a significant reduction in blood glucose and significant increase in plasma insulin levels. In addition, the diabetic rats had decreased levels of plasma total protein, albumin, globulin and albumin/globulin ratio as compared to control rats. After treatment with 3-hydroxymethyl xylitol and...

Lipid composition of microsomal fraction of female rat liver at different stages of growth
It has been reported that lipids are the only macromolecules which display consistency in their pattern of biosynthesis for all living system. In this study, lipid biosynthesis in the liver microsomes of female Sprague-Dawley rats as they aged (3, 7, 12 , 16 and 20 weeks) was studied. The microsomes were isolated by homogenization and centrifugation. The aliquot of the microsomes and soluble enzymes fraction...

Glutathione S-transferase activity of erythrocyte genotypes HbAA, HbAS and HbSS in male volunteers administered with fansidar and quinine
In vivo investigations were carried out to ascertain the comparative levels of erythrocyte GST activity between non-malarious and malarious male subjects of HbAA, HbAS and HbSS erythrocyte genotypes, administered with fansidar and quinine. The incubation of human erythrocytes with 1-chloro-2,4-dinitrobenzene (CDNB) resulted in almost quantitative conjugation of glutathione (GSH) to form...

Hepatoprotective potential of crocin and curcumin against iron overload-induced biochemical alterations in rat
The present study was undertaken to evaluate the possible ameliorating effect of crocin and curcumin on certain biochemical alterations associated with iron overload-induced liver injury in rats. 5 groups of rats were used, a normal control group received daily i.p. injections of saline and 4 groups received daily i.p. injections of ferric nitrilotriacetate (FeNTA) for 8 successive...

Modulation of di- (2- ethylhexyl) phthalate induced hepatic toxicity by Apium graveolens L. seeds extract in rats
In the present study, the hepatoprotective activity of methanolic extract of Apiumgraveolens L. (celery) seeds was tested against Di-(2- ethylhexyl) phthalate(DEHP) induced hepatotoxicity in rats. Oral administration of DEHP (1000 mg/kg b.wt/day) for 6 weeks in rats caused a significant increase in the levels of serum marker enzymes like serum glutamate oxaloacetate transaminase (SGOT), serum...

Direct ex vivo effects of herbal extracts on serum bilirubin in neonatal blood samples
Herbal drug therapy is a common practice adopted in traditional and alternative medicine and has been used in the treatment of neonatal jaundice or hyperbilirubinemia from ancient times. This is done with the help of different herbal extracts and using different treatment methods. The knowledge of new possibilities and the fact that herbal drugs have been used in some communities for a long time, clarifies...

Toxic effects of aqueous stem bark extract of Cassia sieberiana on some biochemical parameters in rats
The aqueous extract of Cassia sieberiana stem bark was administered to groups of 4 albino rats (160 ± 10 g) at 0, 20, 60 or 180 mg/kg body weight daily by gavages for six weeks. A 7% decrease in mean body weight gain was observed in the group treated with the highest concentration of the extract (180 mg/kg). Groups treated with the extract showed significant (p < 0.05) increase in serum...

Mechanisms of arsenic toxicity and carcinogenesis
Industrialization has excessively modified the discharge and distribution of arsenic in the environment through natural and anthropogenic activities. Gastrointestinal tract, Lung and Dermal absorptions account for various adverse effects associated with arsenic toxicity. The knowledge of arsenic biotransformation holds the trivalent species (DMA3+ and MMA3+) accountable for most arsenic toxicity with...

Effects of sodium ion and water hyacinth extract in the production of Curvularia pallescens in culture media
An investigation was conducted on the pH, nutritional and cost benefit of the use of different substrates for the production of Curvularia pallescens Boedijn. The growth of the organism was examined at pH range between 5.5 and 8.6 and on different growth media, potato carrot agar (PCA), potato dextrose agar (PDA), sabouraud agar (SA), tap water agar (TWA), water hyacinth agar (WHA) and Czapek-Dox...

Anti anaemic properties of Scoparia dulcis in Trypanosoma brucei infected rabbits
A major feature of infection with trypanosomes is the development of anaemia. In this study, the effect of Scoparia dulcis (Atiotiousha in Akoko-Edo) onTrypanosoma brucei induced anaemia was investigated in fifteen rabbits divided into three groups of n = 5 over a period of twenty eight days. Changes in Packed cell volume (PCV), Haemoglobin (Hb) concentration, Red blood cell count (RBC), Mean...

Purification and characterization of a laccase from the basidiomycete Funalia trogii (Berk.) isolated in Tanzania
A lignolytic basidiomycete fungus, Funalia trogii (Berk.), was isolated from decayed wood in coastal Tanzania and cultivated in submerged culture. Initially screened crude enzyme filtrate showed complete rhemazol brilliant blue - R (RBBR) decolorization 2,2’-azino-bis (3-ethylbenzthiazoline)-6-sulfonate and guaiacol oxidation after 7 days of incubation. The fungal...

Effects of curcumin and tetrahydrocurcumin on diabetes induced endothelial dysfunction
Diabetes-induced endothelial dysfunction has been well recognized for its underlining causes of oxidative stress. Therefore, several studies have worked on testing active antioxidant agents such as vitamin C and E against diabetes induced oxidative stress to preserve endothelial cells. In the present study, we assessed the effects of plant-derived antioxidant, curcumin and its analog, tetrahydrocurcumin (THC)...
