Corn pollen stored at super low temperature in liquid nitrogen (-196℃) may maintain its viability for a long period.After 321 days the viability was about 85.8% tested by the succinic acid dehydrogenase assay and the fertility of hand pollination was 96.6%. The major technical measures successful storage were: 1.The pollen collected from field must be dried before storage With the moist- ure content dropping to 15.5%—13%.Then it may be used for storage. 2.After taking from liquid nitrogen.The frozen pollen must...

Corn pollen stored at super low temperature in liquid nitrogen (-196℃) may maintain its viability for a long period.After 321 days the viability was about 85.8% tested by the succinic acid dehydrogenase assay and the fertility of hand pollination was 96.6%. The major technical measures successful storage were: 1.The pollen collected from field must be dried before storage With the moist- ure content dropping to 15.5%—13%.Then it may be used for storage. 2.After taking from liquid nitrogen.The frozen pollen must be thawed imm- ediatly in a waterbath at 35℃ for two minutes.This would give the best result. 3.The preserving vessel must be good for thawing,thus a thin polyeth.lene tube with an inner diameter of about 2 mm was used。

液态氮(-196℃)中超低温贮存玉米花粉可以有效地保持其生活力。贮存成功的关键是花粉含水量要低;冷冻花粉的解冻速度要快,温度要合适;采用的贮存器具要有利于迅速冷冻和解冻。

In the present experiment, the skin and striated muscle in 23 rabbits were frozen for 3 minutes with a liquid nitrogen cryosurgical probe (- 190℃) of 6 mm in diameter. The local temperature of freezing area was measured simultaneously.

本实验用液态氮制冷,以直径为6毫米的圆形冷冻头(-190℃),冷冻家兔皮肤和横纹肌3分钟,同时测量温度,实验结果表明,冰球平均直径分别为20毫米19毫米。在冰球内部存在着温度梯度,在冷冻后15分钟、1天、3天、7天、14天、28天、42天和70天,分别各处死2或3只家兔,作组织学切片观察,冷冻后3天,冷冻坏死最严重,28天时再生修复基本完成。和前文报道相比较,在同样的冷冻条件下,家兔肝脏的冷冻损伤要比皮肤和横纹肌严重。冷冻损伤后肝脏的修复最为明显。冷冻后70天肉眼观察,可见肝脏留有小的疤痕,但是皮肤和横肌纹留下的疤痕不明显。本研究为临床冷冻治疗提供了实验依据。

本文介绍一种新型冷刀的基本结构和性能,物理实验和动物实验的结果以及临床治疗效果。并与目前国内外普遍使用的基于喷洒液态氮而设计的冷冻器作了比较。实验及临床应用的初步结果表明,这种浸冷式冷刀疗效显著、操作方便、成本低廉且节省液氮。文章还进一步讨论了扩大临床使用的范围。
