partitioned with the ethyl acetate four times for obtaining a second water layer and a etoac layer the obtained etoac layer is named as dcmpe then the second water layer is partitioned with the n butanol three times for obtaining an n butanol layer named as dcmpb and a third water layer named as dcmpw effect of the alcohol extract of dendrobii caulis on the mice having diabetic angiopathy induced by the glycated albumin four sets of bablc c mice aged 8 weeks are fed with the forage containing various amount of the methanol extract of dendrobii caulis 0 mg kg day 1 g kg day 200 mg kg day 40 mg kg day each set has three mice the mice are treated with glycated mice serum albumin mag via the tail vein injection 2 5 mg time twice week for three weeks then the mice are continuously fed with the forage containing the methanol extract of dendrobii caulis for two weeks the mice are dissected in order to prepare wax embedded sections of the eyes liver and kidney in which the pathological change are observed by the he stain effects of the extract and purified component of dendrobii cauli on rpe function phagocytosis please refer to fig2 which is the bar chart illustrating the effects of the methanol extract of dendrobii cauli on the rpe function phagocytosis as shown in fig2 it 39 s known that various concentrations 0 1 1 10 u03bcg ml of the methanol dcm extract of dendrobii cauli can accelerate the phagocytosis of rpe the relevant experimental contents are simply described as follows 1 u00d7 10 4 rpe.
