Details on test animals and environmental conditions:

Environmenta Conditions:
Animals were housed under standard laboratory conditions, environmentally monitored air-conditioned room with adequate fresh air supply (12 to 15 air changes per hour), room temperature 20.0 to 22.6 °C and relative humidity 48 to 67 %, with 12 hours flourescent light and 12 hours dark cycle. The temperature and relative humidity were reccorded once daily.
Housing:
A maximum of four animals were housed in a standard polypropylene cage (Size L 290 x B 220 x H 140 mm) with stainless steel mesh top grill having facilities for holding pelleted feed and drinking water in bottle fitted with s´tainless steel sipper tube. Clean sterilized paddy husk was provided as bedding material
Feed:
Teklad Certified (2014SC) Global 14 % Protein Rodent diet - Pellet, manufactured by Envigo, was provided ad libitum to the mice throughout the experimental period
Water:
Water was provided ad libitum throughout the experimental period. Deep bore-well water passed through activated charcoal filter and exposed to ultraviolet rays in Aquaguard water filter with purifier was provided in plastic water bottles with stainless steel sipper tubes.
