Although lactase activity in adult rats is believed to be low, we have found it to be elevated during lactation. Our study relates lactase activity measured enzymatically and histochemically with immunological and morphological changes in the jejunum of lactating, pregnant, and nongravid adult rats, suckling and weanling pups. Jejunal sections were collected for light and fluorescent microscopy. Villus measurements were made on H&E sections using Jandel Video Analysis. Lactase was demonstrated… CONTINUE READING
