摘要： A simple and rapid method for multiple shoot formation in vitro from immature embryo axis explants of Carica papaya L. cvs. Honey Dew, Washington and Co2 is described. Multiple shoot regeneration was achieved by culture of the explants on modified Murashige and Skoog (MS) medium supplemented either with thidiazuron (TDZ;0.45-22.7 muM) or a combination of benzylaminopurine (BAP;0.2-8.84 muM) and naphthalene acetic acid (NAA;0.5-2.64 muM). Highest frequency of shoot regeneration occurred on medium supplemented either with 2.25 muM TDZ or a combination of BAP (4.4 muM) and NAA (0.5 muM). Composition of the basal media influenced the frequency of multiple shoot initiation. Stunted shoots regenerated at 4.5 muM and higher concentrations of TDZ. Such shoots could, however, be elongated by transfer to medium containing 5.7 muM GA(3). Rooting of the regenerated shoots was achieved in presence of indolebutyric acid (IBA;4.92-19.68 muM), however, least response was in presence of 14.7 muM IBA. Rooted plants were hardened and transferred to Pots.

关键词： anophthalmia   exencephaly   retinoic acid  

摘要： The purpose of this study is to describe the eye malformations associated with exencephaly observed after retinoic acid (R.A.) administration during gestation in white rat embryos. R.A. suspended in corn oil was given to 13 pregnant rats by gastric intubation. They received various oral doses of R.A. (from 0 to 30 mg/kg b.w. a day) from day 7.5 to 11.5 with an additional dose on day 14.5. No abnormalities have been found in the control groups. The embryos from the treated groups showing anophthalmia and exencephaly were chosen for histological study. The microscopic examination points out dose-dependent abnormalities from absence of eye structures to hypoplastic and atypical more or less compact lens vesicle.

摘要： 目的　通过观察可溶性人类白细胞抗原G(sHLA G)在体外受精 胚胎移植 (IVF ET)后自然流产胚胎组织和绒毛膜癌组织中的表达 ,以探讨sHLA G在滋养细胞中的表达及其与胚胎发育的关系。方法　应用免疫组织化学标记法 ,检测 14例IVF ET(IVF ET组 )后自然流产绒毛组织和 6例绒毛膜癌 (绒毛膜癌组 )组织中的sHLA G表达情况 ,按染色深浅分为阴性、阳性及强阳性 ;并与 10例正常绒毛 (正常绒毛组 )组织进行对照。结果　 (1)IVF ET组仅 1例sHLA G表达阳性 (1/14) ,其余均为阴性或弱阳性 ;绒毛膜癌组sHLA G表达全部强阳性 ;正常绒毛组sHLA G表达全部为阳性。 (2 )3组患者的sHLA G表达部位主要位于绒毛的细胞滋养细胞。结论　sHLA G在正常绒毛和绒毛膜癌的滋养细胞中呈高表达 ,在IVF ET后自然流产的绒毛组织中表达明显下降 ,表明sHLA
