Maternal acceptability of radiation exposure to children - Relationship with maternal knowledge about radiation exposure influence on children -
The maternal acceptability of radiation exposure to her children was examined and was compared with her knowledge about radiation exposure influence on children to prevent over-care to children. It is thought to be important to prevent excessive confusion or over-care to children due to lack of mother's knowledge and understanding about radiation in the case of nuclear accidents. A questionnaire survey was conducted and the results were tested by Wilcoxon signed rank test. It was found that the degree of knowledge increased the acceptability of the exposure. It leads to the conclusion that providing appropriate information to mothers on radiation exposure to children could improve their self-efficacy regarding care for their children and be effective in preventing over-care.departmental bulletin pape
Effect of Intravaginal PRID Insert on Uterine Involution and Conception Rate in Early Postpartum Japanese Black Cows
Effect of progesterone-releasing intra vaginal device (PRID) with estrogen (E2) capsule on postpartum uterine involution and conception rate with timed artificial insemination (TAl) were investigated in Japanese Black Cows. On the day when GnRH-B (GnRH-Buserelin) or PGF2α (Prostaglandin F2α) analog was administered on Day 0 (30 days after parturition), the ratio of cows possessing functional corpus luteum (CL) and plasma progesterone concentrations on Day 7 were significantly increased (P < 0.01) as compared on Day O. From Day 7 to Day 16, PRID was inserted into the vagina of cows. At the time of the PRID removal, PGF2α analog was administered, and E2 at 24 h or GnRH-F (GnRH-Fertirelin) at 48 h after PRID removal was treated, and TAl was performed at 56 h after PRID removal. The conception rate by TAl was increased in the cows that possessing functional CL compared in the cows without CL on Day 7. Also, the uterus significantly involuted with their diameter from 40.5 ± 6.2 mm on Day 0 to 33.4 ± 3.2 mm on Day 28 (P < 0.01), and the viable bacterial count in the external uterine orifice (CFU) showed a tendency to decrease from 2.6 ± 3.5 CFU on Day 0 to 1.0 ± 1.2 CFU on Day 28 (P = 0.63). In conclusion, the activation of folliculogenesis with PRID insertion in early postpartum have promoted the uterine involution, and contributed the increase of the conception rate by TAl.黒毛和種牛において, 分娩後の子宮修復や定時人工授精(定時AI) に対するエストロジェン(E2)カプセルのついたプロジェステロン(P4)徐放剤(PRID)の効果を調べた. その結果, Day 0(分娩後30日)にGnRH-B(酢酸ブセレリン10μg) か, PGF2α(クロプロステノール500μg)を投与すると, Day 7で卵巣に機能的な黄体のある牛が増加し, 血中P4濃度もDay 0 と比較し有意に上昇した(P<0.01). 今回, Day 7からDay 16まで腟内にPRIDを挿入, 抜去時にPGF2αを投与, その後24時間に安息香酸エストラジオール1mgまたは48時間にGnRH-F(酢酸フェルチレリン100μg)を筋肉内投与して, 56時間に定時AIを行った. その結果, 定時AIの受胎率はDay 7に黄体がない牛よりもある牛で高い傾向にあった. また, Day 0からDay 8にかけ, 左右子宮角の長さは有意に短くなり(P<0.01), 同時に外子宮口の細菌数も減少する傾向にあった. 結論として, 分娩後早期からの卵巣賦活とPRID処置は, 子宮修復を促し, 受胎率の向上に寄与することが示された.departmental bulletin pape
Effect of hormone mixture (PG600®) treatment at weaning on ovarian findings and reproductive performance in the first farrowing gilts
Hormone mixture (PG600® : combination of eCG 400IU and hCG 2001U) treatment at weaning increased service rates within seven days post-weaning, shortened interval to the first insemination and increased total farrowing rates in the first farrowing gilts (n=108) compared to the saline treated controls (n=184). Ovarian findings in PG600® treated gilts (n=11) and saline treated controls (n=12) were monitored with transrectal ultrasonography and that revealed the increments of follicular populations in a diameter of 5-7 mm, diameter of the largest follicle and number of ovulations. Plasma concentrations of estradiol and progesterone in luteal phase were increased in PG600® treated gilts.離乳時の初産豚108頭に, PG600®(eCG400IUとhCG200IUの合剤)を投与したところ, 無投与の対照群(n=181)に比べて離乳から7日以内の交配率が増加し, また初回交配までの日数の短縮, 並びに離乳した母豚に対する総分娩率の増加がみられた. 同様に初産豚にPG600®を投与した処置群(n=11)と生理食塩液を投与した対照群(n=12)について, 離乳後の卵巣所見を経直腸超音波検査法により観察したところ, 処置群で離乳後2~3日における直径5~7mmの卵胞数と最大卵胞直径の増加があり, 排卵数が増加した. また, 発情後の処置群では, 血中E2濃度と黄体期における血中P4濃度の上昇がみられた.departmental bulletin pape
