  • This study was conducted to examine the viability of Korean native striped cattle (Bos namadicus Falconer, Chikso) clone embryos after embryo transfer. Chikso somatic cell nuclear transfer (SCNT) embryos were produced by fusion of ear skin cells derived from a female Chikso with enucleated oocytes matured in vitro for 18-24 hr. After in vitro culture of SCNT embryos for 7 to 8 days, fresh or vitrified blastocysts derived from SCNT were transferred into a uterine horn of recipient cows. Fifteen of total 43 recipients were pregnant at Day 50 and 4 recipients were maintained to term. Three IVF-derived calves and 1 clone Chikso calf were born. Pregnancy rate was higher when fresh embryos were transferred to recipients compared to vitrified embryos, but development to term was not different between both groups. The clone Chikso calf died at 5 days after birth due to the fullness of amniotic fluid in rumen and the infection of umbilical cord. The result of the present study shows that clone Chikso calf can produced from the embryo transfer of SCNT embryos, however, solution of abortion problem is necessary to improve the cloning efficiency.

  • The assessment of reproductive potentials of female gayal under semi-intensive management was conducted with 18 animals in Bandarban hilly area of Bangladesh. Age at first estrous (days), age at first conception (days), length of estrous cycle (days), number of service per conception (natural), gestation period (days), age at first calving (days), and calving interval (natural service) (days) of gayal were $598.2{\pm}168.44$, $723{\pm}169.94$, $21.86{\pm}2.93$, 1.41, $296.05{\pm}3.87$, $1014.42{\pm}260.32$ and $465{\pm}80.48$ respectively. Daily milk yield and lactation length of gayal were $304.98{\pm}30.46ml/day$ and $116.67{\pm}8.08days$. Gayal male calves had higher birth weight (19.67 kg) than female calves (15.58 kg) in first lactation. Birth weight increases in second and third lactation than first lactation in both male and female calves. Highest conception rate observed in winter season and 70.60% successful conception occur when service was given within 21-30 h of estrous. Maximum number of female gayal use to come in estrous in winter and calved in monsoon and autumn. Cervicitis and irregular heat were the most reproductive problems followed by metritis, case of abortion, anestrous and repeat breeding. From this study it was observed that the reproductive performance of gayal is very close with the domestic cattle. It may use as beef cattle for the hilly regions of Bangladesh.

  • Purpose: This study is descriptive research to identify characteristics and childbirth experience of women who selected delivery with midwives. Methods: The research methods included structured questionnaires, open questions and charts and data were collected from March 2009 to May 2010 at one midwifery clinic. The 108 data of primipara and multipara were analyzed using descriptive statistics and grouping in same meaning. Results: The general characteristics of participants were age of 31~35, housewife, college or university graduate, religion 'yes', and economic state 'middle'. The obstetric characteristics of participants were abortion rate of 23.1%, none complication to pregnancy and delivery of 97.2%, and none postpartum complication. This study was analyzed using positive experiences of 3 categories, that is 'comfortable and natural childbirth', 'satisfaction and trust to personal care of midwives', and 'experience of baby-and-family-centered childbirth' and negative experiences of 3 categories, that is 'improvement of healthcare environment', 'insufficient facilities and nursing care', and'burden of cost'. Conclusion: This study is significant, since it investigates in the absence of domestic research on the characteristics of women who delivered at midwifery clinic. Thus, this study provided basic data on the characteristics of women who delivered at midwifery clinic.

  • This experiment was undertaken to investigate the effect of splenectomy on the hematology and maintenance of pregnant rats. Those animals that had shown regular 4 or 5 day estrous cycles for more than two cycles were used. The day after mating ws designated Day 0 of pregnancy. Spleen was removed from Day 0(early), 6(middle) and 13(late) of pregnant rat, respectively. Blood was collected on Day 1, 7, 14 and 21 of the pregnancy. 1. The total serum protein was increased significantly (P<0.05) to the progress of pregnancy in control rat. All rats that splenectomized groups were decreased significantly(P<0.05) at Day 21 of pregnancy than control rats. 2. Albumin was not significantly changed. 3. Globulin was decreased significantly(P<0.05) between contol and middle treatment at Day 7, 14 of pregnancy. 4. Glucose was increased for the due to the pregress of pregnancy. It was no significance differences among the each groups. 5. Rate of abortion was increased in groups of early and middle of splenectomy compared with control. 6. Period of pregnancy was delayed in middle and late splenectomized gruops companed with control. 7. Litter size was lowed significantly (P<0.05) in early and middle splenectomized groups compared with control.

  • Animal clones derived from somatic cells have been successfully produced in a variety of mammalian species such as sheep, cattle, mice, goats, pigs, cat and rabbits. However, there are still many unsolved problems in the present cloning technology. Somatic cell nuclear transfer has shown several developmental aberrancies including high rate of abortion in early gestation and increased perinatal death. These developmental failures of cloned embryos may arise from abnormal reprogramming of donor genome and/or incomplete cloning procedure. We have found that overall genomic methylation status of cloned bovine embryos is quite different from that of normal embryos in various genomic regions, suggesting that the developmental failures of cloned embryos may be due to incomplete reprogramming of donor genomic DNA. Many of the advances in understanding the molecular events for reprogramming of donor genome will more clarify the developmental defects of cloned embryos.

  • Traumatic uterine rupture is uncommon but can be fatal and life-threatening for both the mother and infant. In addition to complications caused by trauma itself, such as pelvic fracture, gestational complications such as placental abruption, abortion, premature labor, rupture of membranes, maternal death, and stillbirth can occur. In particular, fetuses have been reported to have a high mortality rate in cases of traumatic uterine rupture. A 35-year-old pregnant female patient fell from the fourth floor and was admitted to our trauma center. We observed large hemoperitoneum, pelvic fractures, and spleen laceration, and the fetus was presumed to be located outside the uterus. The pregnant woman was hemodynamically unstable. Although the fetus was stillborn, angioembolization and surgical treatment were properly performed through collaboration with an interventional radiologist, obstetrician, and trauma surgeons. After two orthopedic operations, the patient was discharged after 34 days. This case report suggests the importance of a multidisciplinary approach in the treatment of pregnant trauma patients.
