 note = {Lectin bindings on the surface of unfertilized mouse ova immediately after ovulation were histochemically examined, and were compared among 30-day-old, 60-to 90-day-old, 180-to 210-day-old and 270-day-old mice. The bindings of PNA, GS-l, DBA, SBA, BPA, MPA, GS-ll, WGA and Con A were observed from a weak to an intense degree on the cell surface of ova in mice from different age groups, but those of UEA-l and LPA were not. Although the strength in bindings of PNA, DBA, SBA, GS-ll, BPA, WGA and Con A did not differ among the age groups, the strength of GS-l and MPA bindings intensified in 270-day-old mice. From the results, it may be said that the glycoconjugates on the cell surface of mouse ova immediately after ovulation contain galactose, N-acetylgalactosamine, N-acetylglucosamine and mannose, and that the amount of galactose and N-acetylgalactosamine increases as the animals get older., 30日齢、60ないし90日齢,180ないし210日齢および270日齢のマウスの未受精卵子について,表面のレクチン結合が動物の加齢に伴ってどのように変化するかを組織化学的に調べた.UEA-lとLPAの結合はすべての動物の卵子でみられなかったが,PNA,DBA,SBA,BPA,GS-ll,WGAおよびCon Aの結合は,いずれの日齢の動物の卵子においても常に弱度ないし強度に認められ,各日齢の動物の間で結合の強さに変化はみられなかった.一方,GS-lおよびMPAの結合は,30ないし210日齢の動物の卵子では中等度および弱度であったが,270日齢の動物の卵子では強まり、強度および中等度になった.以上の結果から,排卵直後のマウス未受精卵子表面の複合糖質はガラクトース,N-アセチルガラクトサミン、N-アセチルグルコサミンおよびマンノースを含んでおり,このうちのガラクトースとN-アセチルガラクトサミンの量は加齢動物の卵子で増加することが推察された.},
