ABSTRACT
The normal growth of blood vessels is the result of dynamic balance of angiogenic factor and inhibitory factor in vascular tissue.However, when the balance is broken, the growth of new blood vessels will be induced.Endogenous angiogenesis inhibitory factor, is a group of negative feedback molecules produced by the body itself that inhibit angiogenesis.Its function of inhibiting angiogenesis is mainly realized by promoting the binding of angiogenic factor to its receptor, or its downstream angiogenesis signal, or promoting vascular endothelial apoptosis.The study of angiogenesis inhibitory factor has potential clinical significance for the prevention and treatment of retinal neovascularization.Recent studies on retinal neovascularization inhibitory factor are reviewed in this paper.
ABSTRACT
Objective To observe the influence of longmuzhuanggu powder(LMZGP)on gastroenteric movement and plasm motilin(MTL)in rats.Methods Rats were randomly divided into control group,model group,LMZGP large dose group,LMZGP middle dose group,and LMZGP low dose group.To establish the model of disorder of gastric depletion and small intestinal advancement by using maxolon,atropine,neostigmine and adrenaline.Gastric emptying and intestinal progradating rates in mice were tested with black nutritious semi solid cataplasm.Level of MTL in hemtatoplasma was tested by radio immunoassay.Results Maxolon accelerated gastric depletion and neostigmine accelerated intestine propagation and heightened the level of MTL in hematoplasma(P_a
