  • This study have a object to found out the effects of oriental herb medicine, Antaeeum, to dams of rats and their offsprings. The Antaeeum was savaged to female Sprague-Dawley rats at a dose of 5 mg/kg/day for 3 weeks during gestation periods. Dams of rat were sacrificed at 20th day of gestation, and were observed major internal and reproductive organs. Approximately live fetuses in the 20th days of gestation were selected randomly and examined with stereo microscopes. Others offsprings were fixed with 95% ethanol for skeletal examinations. The fixed fetuses were stained with alcian blue and alizarin red S to observe skeletal variations or malformations. Maternal body weight of Antaeeum treated dams have a tendency of increasing compared with control dams. There were no significant difference in internal and reproductive organs of weight or findings. The spleenic organ relative weight of treated dams were decreased compared with the control significaltly (p<0.05). There were no significant changes between two groups in blood chemistry and hematological values. There were no significant changes in number of corpus luteum, implantation, live fetuses and implantation rate, delivery rate, late resorption rate and sex ratio. But in the Antaeeum treated group showed lower early resorption rate than that of the control dams. Fetal body weight and number of fetus a dam at Antaeeum treated group were higher than that of control group. The fetuses of dams treated with Antaeeum didn't induced external malformations. Vertebral and sternal variations were observed in Antaeeum group, but compared with the control, those variations were not significant. The ossification numbers of rib, cervical, thoracic, and lumber were normal. Fetuses treated with Antaeeum to the dams showed no significant difference in the number of caudal vertebra (P>0.01). From these results, it can be concluded that Antaeeum showed no toxicity effects on maternal side especially on body weight, early resorption rate, and number of live fetuses. Also there were no significant changes on maternal organ weights except spleen, hematological data, reproductive organs. Although skeletal variations were examined at vertebra and sternum, this Antaeeum could not induced significant choses in bone malformation.

  • The objective of this study was to characterize the adverse effects of Ahnjon-Yichun-Tang during early pregnancy. Following successful mating, female Sprague-Dawley rats were given Ahnjon-Yichun-Tang(AYT) extract by oral administration daily with dose of 150mg (n=10), 300mg(n=10), 450mg(n=10) for 20 days of pregnancy. The rats in Control group(n=10) were orally administrated with Saline. All pregnant rats of Ahnjon-Yichun-Tang-treated and Control groups were sacrificed on day 20 of pregnancy. The pregnancy outcome was determined and the internal and reproductive organs of pregnant rat were observed. The fetuses were examined for the presence of various developmental toxic endpoints and stained with alcian blue and alizarin red S, and observed skeletal malformations. The results obtained in this study represent that there is no significant changes between Control and Ahnjon-Yichun-Tang-treated groups in body weight, organ weight, blood chemistry values, hematological values and pregnancy indexes of pregnant rat. The skeletal malformation of fetus was not observed as well. These results suggest that oral administration of Ahnjon-Yichun-Tang does not produce either maternal or developmental toxicity.

  • Nager syndrome is a rare malformation complex characterized by facial, limb, and skeletal morphogenesis. The mode of inheritance has not been definitely established. Major karyotypic abnormalities were seldom associated with this syndrome. We report on an infant with Nager acrofacial dysostosis that was associated with 45,X monosomy. This baby was born to a 36-year-old multigravid woman after 37 weeks of gestation and with maternal hydramnios. The baby girl died of airway obstruction due to retruded tongue 3 hours after birth. Phenotypically, this this patient had mandibulofacial dysostosis, radioulnar synostosis, hypoplasia and aplasia of thumbs, peripheral edema and apparently normal genital organs. We confirmed that major chromosomal anomaly including 45,X monosomy could be associated with Nager syndrome, although its pathogenetic significance remains unanswered.

  • Constitutional trisomy 8 mosaicism (CT8M) is a relatively rare aneuploidy in humans with characteristic phenotypes including typical craniofacial feature (such as deformed skull, prominent forehead, low-set and/or dysplastic ears), skeletal malformation, cardiac anomaly, renal malformation, cryptochidism, varying degree of developemental delay. Due to the extremely variable phenotypic and cytogenetic expression, CT8M has gone undiagnosed in certain patients. We report a 28-year-old women with secondary amenorreha without characteristic CT8M phenotype. Chromosomal analysis showed a CT8M (47,XX,+8[9]/46,XX[41]).

  • We examined the radioprotection effects of acupoint (acupuncture point) stimulation during organogenesis stages of ICR mice. Pregnant mice received 1.5 Gy whole body X-irradiation on day 8 of gestation, which is the early stage of organogenesis. The embryonic death rate and teratogenesis rate by radiation were examined. Electroacupuncture to the leg acupoints and/ or transcutaneous stimulation to the back acupoints on the pregnant mice showed no protective effect against irradiation on embryonic or fetal death rate. On the contrary, the strong stimulation resulted in increase in the mortality after irradiation rather than protection. However acupoint stimulation to the pregnant mice never showed harmful effects by itself on embryos. It tended to reduce the skeletal malformations induced by X-ray irradiation. We suspect that acupoint stimulation removed the cells injured by irradiation during embryonic development, resulting in an increase in embryonic death rate and reduction in skeletal anomalies.

  • Incontinentia pigmenti is a rare neurocutaneous syndrome characterized by vesiculobullous skin disease in neonates and infants, a noninfectious disease that should be distinguished from infectious diseases with the neonatal seizure or encephalopathy. This disease is X-linked dominant with Xq28 region abnormalities and often associated with developmental defects of the ocular, skeletal, dental, and central nervous system. Central nervous system involvement in the neonatal period, or complicated by encephalopathy, may cause severe neurologic impairment, retardation or even death. We experienced a case of incontinentia pigmenti in a three-day-old female patient who had characteristic papulovesicular skin lesions and partial seizures with secondary generalization. Histopathological examination favored the diagnosis of incontinentia pigmenti and a brain MRI showed undifferentiated white matters with periventricular nodular lesions.

  • Purpose: Kabuki syndrome is a multiple malformation syndrome that was first reported in Japan. It is characterized by distinctive Kabuki-like facial features, skeletal anomalies, dermatoglyphic abnormalities, short stature, and mental retardation. We report two cases of Kabuki syndrome with the surgical intervention and speech evaluation. Methods: Both patients had velopharyngeal insufficiency and had a superior based pharyngeal flap operation. The preoperative and postoperative speech evaluations were performed by a speech language pathologist. Results: In case 1, hypernasality was reduced in spontaneous speech, and the nasalance scores in syllable repetitions were reduced to be within normal ranges. In case 2, hypernasality in spontaneous speech was reduced from severe level to moderate level and the nasalance scores in syllable repetitions were also reduced to be within normal ranges. Conclusion: The goal of this article is to raise awareness among plastic surgeons who may encounter such patients with unique facial features. This study shows that pharyngeal flap operation can successfully correct the velopharyngeal insufficiency in Kabuki syndrome and post operative speech therapy plays a role in reinforcing surgical result.

  • The experiments were undertaken to evaluate the effects of Bosaengtang in pregnant rats and fetuses. Female Sprague-Dawley rats were orally administered with Bosaengtang at the dose of 5mg/kg/day for 20 days. Pregnant rats were sacrificed at the 20th day of gestation, and observed internal and reproductive organs. Fetuses were randomly selected and fixed in 95% ethanol. Fetuses were stained with alcian blue and alizarin red S, and observed skeletal malformations. The results obtained were as follows : Bosaengtang administered group showed higher maternal body weight than the control group, but both groups showed increase in weight. Bosaengtang administered group showed lower than the control group, and higher liver and kidney weight than the control group, but the differences were minimal. There were no significant changes between the control and treated group in blood chemistry values and hematological values but all the groups were within in normal ranges. There were no significant changes in the number of corpus luteum, implantation, live fetus and implantation rate, delivery rate, late resorption rate, sex ratio, but Bosaengtang administered group showed higher early resorption rate than control group. comparing the control and Bosaengtang group, neonatal body weight and the number of fetuses were increased in Bosaengtang group. The fetuses of dams treated with Oriental medicine didn't showed external malformation. Vertebral and sternal variations were observed in Bosaengtang group, but the differences were not apparent compared to the control group. The number of ribs, cervical, thoracic and lumbar vertebrae were normal. The number of sacral was similar and the number of caudal was increased. Fetuses showed significant difference in the number of caudal vertebrae. (P<0.01) From these results, we can carefully conclude that Bosaengtang showed beneficial effects on maternal body weight, early resorption rate, number of live fetus. There were no significant changes in organ weight, hematoscopy, reproduction organs. External malformation wasn't visible. Skeletal variations were showed in vertebrae and sternum but compared to the control group, these variations weren't much different.

  • Introduction : The experiments was undertaken to evaluate the effects of herbal medicine, Sibjeondaebotang, Yugmijihwangtang, in pregnant rats and fetuses. Female Sprague-Dawley rats were orally administered with the Sibjeondaebotang, Yugmijihwangtang at dose of 5mg/kg/day for 20 days. Pregnant rats were sacrificed at 20th day of gestation, and observed internal and reproductive organs. Approximately live fetuses in the 20th day of gestation were randomly selected and fixed in 95% ethanol. To observe skeletal malformations, fetuses were stained with alcian blue and alizarin red S. Effect on pregnant rats : Maternal body weight of Sibjeondaebotang, Yugmijihwangtang treated group has a tendency to increase compared to that of control group. There were no significant difference in internal and reproductive organs. There were no significant changes between two groups in blood chemistry and hematological values. There were no significant changes in number of corpus luteum, implantation, live fetuses and implantation rate, delivery rate, and sex ratio. But Yugmijihwangtang administered group showed higher early resorption rate than the control group(p<0.05). Also Sibjeondaebotang administered group showed higher late resorption rate than the control group(p<0.05). From the sex ratio, number of females, bigger than number of males in the control group, and more males than females in Yugmijihwangtang administered group(p<0.05).

  • A developmental study of CONP01, a new antiarthritic agent, was conducted in Sprague-Dawley rats. Dosage of CONP01 0, 111, 333, and 1000 mg/kg/day were administered to dams orally from day 6 to day 16 of gestation. Two-third of dams per group were subjected to caesarean section on day day 20 of pregnancy for examination of their fetuses, and the remaining one-third of dams per group were allowed to deliver naturally for postnatal examination of their offspring. There was no change in the dams body weights, food consumptions, specific clinical sings and gross findings. There was significant decrease only in the absolute and relative weights of right ovary in 111 mg/kg treatment group, when compared with the vehicle control, whereas other organ weights were not changed. Moreover, no increase in the frequencies of external, visceral and skeletal malformation of fetuses were observed in the treated groups. These results suggest that the oral NOAEL (no observed adverse effect level) of CONP01 may be over 1,000 mg/kg in dams and fetuses of rats.
