[Effect of anti-androgen and progesterone on development of regrowth antlers in 6 year old sika deer].

To investigate the effects of anti-androgen drugs and melengestrol acetate (MGA) on development of regrowth antlers in 6 year old sika deer, twenty healthysika deerwith similar body weight and antler weightwere randomly divided into five groups by using single factor test design: flutamide (=4), bicalutamide (=4), progesterone acetate (CPA, =4), melengestrol acetate (MGA, =4), control(=4). All deer were fed with same diets and were housed outside together in an opened fence of 15 m×30 m with free access to water and feed. Treatment groups were injected subcutaneously sustained-release agents of the four drugs respectively when two-branched antlers were harvested.

[Research progress on identification and quality control of Cervi Cornu Pantotrichum].

Cervi Cornu Pantotrichum, as a traditional Chinese medicine, has great potential for development. However, the identification and quality control system is not perfect, leading to the market chaos and chronic slow growth in deep processing of Cervi Cornu Pantotrichum. This paper gives an overview of present situation in identification and quality control system of the Cervi Cornu Pantotrichum, and analyzes present problems.
