1 Maternal Behavior 母性行為 Chap 17

2 緒論 Hormone → Maternal Behaviors Hormone: Estrogen, Progesterone, Hormone: Estrogen, Progesterone, Prolactin, etc. Prolactin, etc. 多數研究失敗, 只有極少數成功 多數研究失敗, 只有極少數成功 失敗原因 : proper hormone 失敗原因 : proper hormone proper order, dose level proper order, dose level

3 緒論 Identifying the Humoral Basis of Maternal Behavior 分娩後已出現母性行為之母鼠提供血漿 分娩後已出現母性行為之母鼠提供血漿 48 hr. 內輸血至 virgins 48 hr. 內輸血至 virgins Exposure → Retrieving virgin females exposed to young pups virgin females exposed to young pups 5 days →retrieving (maternal behavior) 5 days →retrieving (maternal behavior) 可為 nonhormonal origin 可為 nonhormonal origin

4 緒論 研究目的 研究目的 驗證假設 : 驗證假設 : 將具有母性行為母鼠之血漿輸於處女鼠 將具有母性行為母鼠之血漿輸於處女鼠 可使得母性行為之出現 可使得母性行為之出現 (e.g.) latency for the appearance of retrieving (e.g.) latency for the appearance of retrieving 快於其他的控制組 快於其他的控制組 方法 : 方法 : 輸血, 測母性行為 輸血, 測母性行為

5 方法 受試者 受試者 32 virgin females, 60 days of age 32 virgin females, 60 days of age 實驗設計 : 單因子受試者間設計 實驗設計 : 單因子受試者間設計 獨變項 : 獨變項 : Maternal plasma: unspecified phases Maternal plasma: unspecified phases Proestrus plasma: proestrus recipient Proestrus plasma: proestrus recipient Diestrus plasma: diestrus recipient Diestrus plasma: diestrus recipient Saline: unspecified phases Saline: unspecified phases Untreated Untreated

6 方法 實驗設計 : 實驗設計 : 依變項 : Maternal Behavior Test 依變項 : Maternal Behavior Test Retrieving Retrieving Crouching over the young Crouching over the young Licking the young Licking the young Nest building Nest building Others Others

7 方法 程序 程序 手術 ( 麻醉 ) 手術 ( 麻醉 ) 恢復 恢復 Maternal Behavior Test Maternal Behavior Test 5 pups, 5-10 days of age 5 pups, 5-10 days of age observe 15 min observe 15 min 1-min every 20-min (next 2 hr) 1-min every 20-min (next 2 hr) 每天測, 直到連續兩天 retrieve pups 每天測, 直到連續兩天 retrieve pups

8 結果 Onset of Retrieving Onset of Retrieving 各組平均數 : Table 1 各組平均數 : Table 1 Table 1 Table 1 統計分析 統計分析 ANOVA: F(3, 28)=9.79 ** ANOVA: F(3, 28)=9.79 ** (except untreated) (except untreated) Maternal < Proestrus, Diestrus, Saline * Maternal < Proestrus, Diestrus, Saline * (Duncan’s New Multiple Range Test) (Duncan’s New Multiple Range Test) Diestrus > Saline * (Duncan’s) Diestrus > Saline * (Duncan’s) Maternal < Untreated (Mann-Whitney, p=.02) Maternal < Untreated (Mann-Whitney, p=.02)
