In this paper we will discuss a new technology and method of applicatication of CO_2 Laser in egg incubation. The specific operating procedure and incubative effect are introduced. Meanwhile the application of CO_2 Laser is compared, with that of He—Ne Laser in method, effect and economic benefit. According to this method, if the eggs are radiated once 0.5~1.0sec, with CO_2 Laser of 10 W export power before the hatch, the hatch ability will increase by 9.6% on an average.

本文研究在禽蛋孵化中的一顶二氧化碳激光应用新技术、新方法。介绍具体操作方法、效果,并与氦氖激光的方法、效果、经济效益加以对比讨论。按本方法,使用输出功率为10W的CO_2激光器,1次照射入孵前的种蛋0.5—1秒,平均提高孵化率9.6%。

Effects of two natural proteinase inhibitors (Trichosanthes inhibitor and Ar-rowhead inhibitor) on human sperm penetration into zona-free hamster oocyteswere investigated. The results showed: (1) 1.0×10~(-3) mol/L Trichosanthes in-hibitor added to the spermatozoa containing medium for a period of preincubationintended to induce capacitation caused a large decrease in the spermatozoa penetra-tion rate (P<0.01), while Arrowhead inhibitor of similar concentration did notshow significant effect.

Effects of two natural proteinase inhibitors (Trichosanthes inhibitor and Ar-rowhead inhibitor) on human sperm penetration into zona-free hamster oocyteswere investigated. The results showed: (1) 1.0×10~(-3) mol/L Trichosanthes in-hibitor added to the spermatozoa containing medium for a period of preincubationintended to induce capacitation caused a large decrease in the spermatozoa penetra-tion rate (P<0.01), while Arrowhead inhibitor of similar concentration did notshow significant effect. (2) The penetration rate of capacitation spermatozoa intozona-free oocytes pretreated with either inhibitor for 0.5 h was similar to that ofthe untreated control. (3) When either inhibitor (1.0×10~(-3)mol/L or 0.5×10~(-3)mol/L) was present in the capacitation sperm in egg incubation medium, the sper-matozoa penetration rate was significantly decreased (P<0.01). (4) When 1.0×10~(-3) mol/L of either inhibitor was present during both the preincubation for capita-tion and the sperm/egg incubation periods, the ability of spermatozoa to penetratezona-free oocytes was significantly decreased (P<0.01). 1.0×10~(-4) mol/L inhibitorsdid not show up significant effect. (5) The motility of the sperm was not affectedby the inhibitors. Thus it is the enzyme system involved in the penetration ofsperm into oocyte affected by the proteinase inhibitors.

本文研究了慈姑和天花粉两种天然的蛋白水解酶抑制剂对人精子穿透去透明带田鼠卵子的影响。结果显示:(1)在人精子获能期1.0×10~(-3)mol/L天花粉抑制剂可使人精子的穿卵率明显下降(P<0.01),而同样浓度的慈姑抑制剂,作用不明显。(2)去透明带田鼠卵子预先用抑制剂处理0.5h,被获能精子的穿卵率和未用抑制剂处理的卵子相似。(3)在获能后的人精子和去透明带田鼠卵子孵育期,两种抑制剂的浓度为0.5或1.0×10~(-3)mol/L时,精子的穿卵率明显下降。(4)在人精子获能期及人精子/去透明带田鼠卵子孵育期,两种抑制剂的浓度为1.0×10~(-3)mol/L时,均使精子的穿卵率下降(P<0.01),而抑制剂的浓度为1.0×10~(-4)mol/L时,作用不明显。(5)抑制剂不影响人精子的活动能力。这样看来,涉及精子穿透卵子的酶体系受到了蛋白酶抑制剂的影响。

Water temperature shows a marked influence upon the incubation period of the eggs of the two species. Within the range of 20—35℃, the higher the temperature, the shorter is the incubation period. The curves of egg incubation rate of both species related to temperature are logistic. They can be expressed respectively by the following formulas:N_1+=1+e~(4.9347-0.1872t)/0.1095 and N_h=1+e~(5.2077-0.2117t)/0.1104 Where, N_n, N_h—rate of D. niedashui and D. hupehensis respectively; t—temperature.When...

Water temperature shows a marked influence upon the incubation period of the eggs of the two species. Within the range of 20—35℃, the higher the temperature, the shorter is the incubation period. The curves of egg incubation rate of both species related to temperature are logistic. They can be expressed respectively by the following formulas:N_1+=1+e~(4.9347-0.1872t)/0.1095 and N_h=1+e~(5.2077-0.2117t)/0.1104 Where, N_n, N_h—rate of D. niedashui and D. hupehensis respectively; t—temperature.When the water temperature increases, the instantaneous hatching rate of both species increases according to the following equations: Y_n=0.0205t—0.3119 and Y_h=0.030t—0.5171.Where, Y_n, Y_h—instantaneous rate of each species; t—temperature.The miracidia of these allied species show a strong positive phototaxis and prefer swimming near the surface of water. The two cercariae shed from the gastropods 18—25 days after infection. They appear to be phototatic and suspending near the surface of water. The cercariae emerge from the snails discontinuously and in spurts at intervals. The emergence peak of the cercariae of both species appears from 8 to 10 am every day. Their emergence begin to reduce囔 by 2 pm and completely cease, after 6 pm.The populations of the two cercarie may also increase in logistic curves. They can be expressed respectively by the integral form of the logistic equations:N_n=209 362.8315/1+e~(4.3368-0.1308t) and N_h=448 376.6514/1+e~(5.8165-0.1495_t)Where, N_n, N_h—population of each species; t—day.
