  Background and Objective: Blood contains low concentration of thiols and some (thiols) are found in the albumin compartment. So far, little or no information exists on the relationship between serum total thiols and albumin in sub-chronic lead intoxication. To examine the relationship between serum total thiols and albumin in sub-chronic lead intoxicated rats supplemented with folic acid and/or vitamin C. Materials and Methods: This study was performed using 40 male albino rats weighing 160-190 g. The albino rats were divided into eight 8 of five each. Group 1-4 were sub-chronically intoxicated with lead fora period of 6 weeks, followed by supplementation with folic acid and/or vitamin C to group 2-7 fora period of 4 weeks. After the 10th week, the experimental rats were fasted overnight and sacrificed, after which their blood samples were collected. Results: Findings from this study revealed statistically significant (p<0.05) decrease in serum total thiols and albumin concentration in the non-supplemented lead intoxicated group as compared to the level observed in the control group. Moreso, combined supplementation of folic acid and vitamin C modulates decreased in the total thiols and albumin concentration and both (thiols and albumin) correlates positively in the co-supplemented (folic acid and vitamin C) lead intoxicated group. Conclusion: Co-supplementation of folic acid and vitamin C could be used as nutrient supplement to simultaneously restored depletion in serum total thiols and albumin concentrations of sub-chronic lead intoxication.

  The aim of this study was to explore the possibility of utilizing agrowastes effectively to convert them into fermentable sugars by the production of in situ enzyme in solid state fermentation, which agrowaste can be used as substrates for the microbial fermentation in the production of commercial viable products. To enhance the usage of abundant agrowaste generated in Malaysia a study was conducted in view of exploring the possibility of utilizing it effectively for the conversion to fermentable sugars. Agrowaste is rich of lignoselulolytic material which can serve as good substrate in solid state fermentation to produce the fermentable sugar. In this study, solid state fermentation was carried out through the flask system in lab skill. We evaluated the production of fermentable sugars by various fungal cultures namely A. niger USM AI1, A. niger II, Trichoderma sp., A. niger F4 and Phanerochaete chrysosporium via solid state fermentation system. Nine different types of lignocellulolytic materials paddy husks, coconut fibre, wood dust, coconut meal, palm kernel cake, sugarcane baggase, tapioca meal, oil palm trunk and oil palm frond were examined. The highest productivity, 57 mg of fermentable sugars per gram substrate was obtained when A. niger USM AI1 was grown on tapioca meal and the biomass of fungus showed about 1.7 mg glucosamine/g substrate. However, about 30.0 mg of fermentable sugars per gram of substrate was obtained when A. niger USM AI1 was grown on oil palm frond and the biomass of fungus showed 1.2 mg glucosamine/g substrate. Lesser yields of fermentable sugar were obtained when paddy husk, coconut fibre, wood dust, coconut meal, palm kernel cake and sugarcane bagasse were used as solid substrates, each yielding less than 6.6 mg of fermentable sugars per gram of substrate. Thus, the nature of the substrate and the suitability of fungi used in the solid state fermentation are important variable contributing to product yield of fermentable sugars in solid state fermentation and can presumably be more economical process for agrowaste utilization.
