摘要
３４头黑白花奶牛，患子宫炎或卵巢疾病而不孕，将其随机分为２组。激光组（２４头）用Ｈｅ－Ｎｅ激光照射交巢穴，７ｄ为１疗程。间歇７ｄ再照射第２疗程。对照组（１０头）不用激光照射。ＲＩＡ法分析血浆β－内啡肽（β－ＥＮＤ）含量。结果发现，激光组病牛血浆β－ＥＮＤ由照射前（第０天）的１１２．８６４±５８．９４７ｐｇ／ｍｌ升高到第１疗程后（第８天）的１７５．６３４±１０４．３１０ｐｇ／ｍｌ（Ｐ＜０．０５），间歇１周后为（第１４天）２３７．６２７±１５３．１３６ｐｇ／ｍｌ（Ｐ＜０．０１），第２疗程后（第２２天）为１９３．４４８±１０４．３７８ｐｇ／ｍｌ（Ｐ＜０．０５）。显著高于对照组同期测定值。同时观察到，激光组发情牛头数为２１头，发情率８７．５％；对照组发情３头，发情率３０％。组间差异显著（Ｐ＜０．０１）。表明激光照射穴位可使病牛β－ＥＮＤ分泌增加。
Thirty four Chinese Black and White dairy cows suffering from metritis and ovarian quiscence were distributed into 2 groups randomly Twenty four were irradiated with Helium Neon laser at point Jiaocao,seven days consecutively in one course of treatment,two courses altogether with 7 days of interval The control group(10 cows) did not receive laser irradiation Plasma beta endorphin contents were radioimmunoassayed The results revealed that the beta endorphin contents in laser treated group increased from the base value of 112 864±58 947 pg/ml (day 0)to 175 634±104 310pg/ml(day 8,P<0 05)after the first course,237 627±153 136pg/ml(P<0 01)after the interval (day 14)and to 193 448±104 378pg/ml(P<0 05) after the second course (Day 22) Statistical differences were found between the contents of the control and laser treated groups Moreover,Twenty one cows showed estrus after laser treatment (87 5%)whilst the control group had 3 estrous cows (30%) The results herein indicate that laser irradiation stimulates endorphin secretion,which participates in the modulation of reproductive functions in dairy cows
