不育

Objective To study the antifertility function of sasanqua saponin sterilant against rodents.

目的 研究油茶皂素不育剂对鼠类的抗生育功能。

The sasanqua saponin sterilant was provided with obvious spermicidal effect in vitro and antifertility function in vivo.

油茶皂素不育剂具有较强的体外杀精活性和体内抗生育功能，可进一步开发成体外杀精避孕药和环境友好型鼠类抗生育药剂。

Results The spermicidal effect in vitro on male mice of the sasanqua saponin sterilant was provided with excellent positive relation in dosage-effect.

测定不同浓度油茶皂素不育剂对雄性小鼠的体外杀精效果和体内抗生育能力。

Methods The spermicidal effect in vitro and the antifertility ability in vivo on male mice of the sasanqua saponin sterilant in different concentration were mensurated.

测定不同浓度油茶皂素不育剂对雄性小鼠的体外杀精效果和体内抗生育能力。

The minimum spermicidal concentration being(0.05 mg/ml) in(3 min) of the sasanqua saponin sterilant was corresponded with nonoxynol spermicide and was lower than mandelic acid(0.1 mg/ml and citric acid(0.25 mg/ml.

结果 油茶皂素不育剂对雄性小鼠呈现出较优的剂量依赖性体外杀精活性，3 min时的最低杀精浓度为0.05 mg/ml，与人用杀精剂壬苯醇醚相当，比扁桃酸(0.1 mg/ml)和柠檬酸(0.25 mg/ml)低。

The sasanqus saponin sterilant was provided with obvious spermicidal effect in vitro and antifertility function in vivo. The sasanqua saponin spermicide or prophylactic and the antifertility medicament against rodents with entironment amity should be exploited in future.

Fruit a schizocarp, disk-shaped, fruit axis as long as or shorter than carpels; mericarps more than 15, laterally compressed and circular with a prominent ventral notch, glabrous or pubescent, 2-celled, proximal cell 1-seeded, distal cell sterile.

果一分果，盘形，果轴等长于或短于心皮；分果爿多于15，侧面压扁和圆形的有一突出腹槽口，无毛或被短柔毛，2室，下部室具1种子，上部室不育。

寻求生育帮助的夫妇并不仅仅是年龄偏大的，他们也是明显的不育夫妇。

The capsule and seed rates at single plant level were up to 41.4%and 20.7%.

不育株自交结蒴率最高达到17.9%，结实率最高达到8.0%。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
