| Sumario: | The purpose of this work is to study mast ce11s under theinfluence of sexual hormones in submaxilar (SM). sublingual (SL)sa1ivary glands. Adult young fernale Wistar rats were used in lotsof 5 animals each. 1) normal 2) castrated 15 days 3) castratedplus estrogen 4) castrate'd plus testosterone 5) normal ma1e.Samp1es of SL.íl and SriG were taken applying routine histo1ogicmethods: HE.AB,PAS-pH 2.5. ATO pH 3,8. Histometry was perforrnedon an area from 15,6 mm to 450X. Variations in the cytochemicalbahaviour and cellular size of mast cel1s were observed in thefema1t;! rats injected with testosterone or estrogen. Fromcuantitative eva1uation we deduce that: a) castration prodecesa significative ir.crease of mast ce11s. b) estrogen andtestosterone do reduce the number os mast ce11s e) in SLG thepopu1atión is significatively minar than in SMG and the steroidinfluence can be hard1y observed. We conclude that: 1" mast cel1sat'e influenced by castration as much as by sexual hor¡nonesinjection in SMG. 2° ihere are signifjcative differences in thenumber of mast ce11s of ma1e and female rats. 3° mast ce11s aremóre sensible to sexual hormones in SMG than in SLG. |
