Group Ⅰ received vehicle and group Ⅱ,Ⅲ and Ⅳ received 500,2500 and 5000 mg/kg of shilajit, respectively.Finally animals were sacrificed and subjected to histopathology and iron was estimated by flame atomic absorption spectroscopy and graphite furnace.Results:The result showed that there were no significant changes in iron level of treated groups when compared with control except liver(5000 mg/kg) and histological slides of all organs revealed normal except negligible changes in liver and intestine with the highest dose of shilajit.The weight of all organs was normal when compared with control.Conclusions:The result suggests that black shilajit,an Ayurvedic formulation,is safe for long term use as a dietary supplement for a number of disoniers like iron deficiency anaemia.展开更多

Incorporation of 15—20% PPS into nylon-6 has provided UL V-0 rating for the system and there is enhancement in tensile and flexural properties. The results obtained on the thermal, crystallization and flow characteristics of the nylon-PPS system upto a loading of 40% PPS are also discussed.展开更多

Brazilian hair treatments, containing high levels of FHO (up to 11%), have become regularly used that have the potential to expose clients to toxic levels in excess of current regulatory standards. We report on a patient who underwent a single hair treatment and subsequently developed an autoimmune disease. We review the relevant literature on autoimmune disease and formaldehyde exposure. Our case adds to existing knowledge and suggests that physicians ask their patients about commercial products that contain formaldehyde when diagnosing autoimmune conditions.展开更多
