The invention provides an ellagic acid reagent and a preparation method thereof as well as an activated partial thromboplastin time (APTT) determination reagent and an APTT kit and relates to the field of clinical diagnosis reagents. The preparation method comprises the following steps: adding ellagic acid into calcium-free purified water and rapidly stirring to uniformly disperse the ellagic acid; adding an alkaline buffering solution or inorganic alkali; rapidly adding an acidic buffering solution or organic acid and inorganic acid within 10min after the ellagic acid is added; adding metal ions; adding amino acid and a derivative thereof to obtain a buffering solution; furthermore, adding the calcium-free purified water into rabbit brain phospholipid and uniformly mixing and emulsifyingto obtain emulsified phospholipid; adding the emulsified phospholipid into the buffering solution and rapidly stirring and uniformly mixing to obtain the ellagic acid reagent. The technology is simpleand rapid and has detailed descriptions. The activated partial thromboplastin time determination reagent comprises the ellagic acid reagent and a calcium chloride reagent and has good stability. TheAPTT kit containing the activated partial thromboplastin time determination reagent can be used for directly replacing an imported high-stability APTT kit.

The invention relates to an egg laying poultry feed additive for supplying and adding a dietary factor. The constituents and the weight percentages thereof are as follows: soy protein bioactive peptides powder 25-30%, allium mongolicum powder 15-20%, sunflower seed powder 2%-5%, linseed 3%-5%, hemp seed powder 3%-5%, rabbit brain powder 5%-10%, perillaseed powder 5%-10%, black sesame seed powder 5%-10%, parslane herb powder 5%-10%, brown sugar 5%-10%, chicken's gizzard-membrane powder 2%-5%, dried orange peel powder 3%-5%, and cucumber seed powder 2%-5%. The egg laying poultry are fed with the feed additive and basal feed by the ratio of 1:10-1:20. Through the transformation of the feed additive in the egg laying poultry bodies, poultry eggs with low cholesterol and high HDL content (about 15 mg) are obtained. The poultry eggs eaten by people can increase the HDL level in human body by 80% and above, obviously relive the symptom of arteriosclerosis, and radically cure cardio-cerebrovascular disease after people eat the eggs for a long period. The feed additive has the advantages of high effective constituents and rich functional constituents. The materials in the feed additive arenatural plants which grow widely, are easy to grow, get and free of toxins, can be eaten by people, fed to the poultry and used as medicine, and is suitable for the development and application of thepoultry eggs with high nutritional value and health protection function.

The invention discloses a preparation method for a rabbit brain tissue factor freeze-drying preparation. The preparation method comprises the following steps: taking a fresh rabbit brain and stripping meninx and blood vessels; removing a brainstem and washing by using normal saline; putting the rabbit brain into a cleaning mortar and adding acetone until the rabbit brain is immersed; grinding by using a grinding hammer and pouring off the acetone; repeating for three times; filtering the acetone by using filtering paper; putting the rabbit brain into an oven of 37 DEG C and paving to evaporate and dry the acetone; adding the normal saline; uniformly agitating and putting a mixture into a constant-temperature water bath of 37 DEG C to be pre-heated and activated, incubated and agitated; centrifuging for separating; taking liquid supernatant and filtering to obtain a rabbit brain FIII tissue factor suspension solution; adding the rabbit brain FIII tissue factor suspension solution into a small bottle; freezing-drying, exhausting and pressing a bottle to prepare the rabbit brain tissue factor freeze-drying preparation, and storing at -20 DEG C. With the adoption of the scheme, the technology is very mature, the quality is very stable and the guarantee period is very long; the preparation method is very convenient to use; the preparation method has very high medical teaching, scientific research, clinical diagnosis and treatment and economic values.
