RESUMEN
By comparing three cultivation techniques of Astragalus mongholicus, i. e. direct seeding, furrow erectplanting and furrow flat planting, it was found that furrow flat planting is the optimum technique. Its yield onplain ground was 1. 26kg/m' and 0. 96kg/m_2 on mountainous area- Root of the plant was longer, thicker andheavier than that produced hy other cultivation techniqlles. Its input/output ratio was l s l2' 94 on plaingrounfl and l: 9. 95 on n1ollntainous area. Therefore,it can be considered as a scientifically justifiable,economically technique for the cultivation of A. mongholicus on both plain ground and mountainous regions.
RESUMEN
Transport of gossypol by rat cauda epidldymis has been studied using microperfusion technique. It was found that gossypol entered ep-ididymal duct at very much limited rate in spite of its high plasma level. There was no difference between the aqueous & liposome formulations of gossypol to get into the epididymal duct from the blood. Since it was indicated in a previous paper that the transport rates of the 2 gossypol formulations via the blood-testis barrier were quite different. It is suggested that the transfer mechanism in test-is & epididymis may be different.
