저자들은 23세 및 26세 초산부로서 임신중독증을 주소로 입원하여 제왕절개술로 생아를 분만하고 치료된 예이다. The uterus didelphys is one of the rare congenital anomalies, and it was even judged incompatible with life bofore. Complete duplication occurs from faulty fusion of the two Mullerian ducts and during the first two early months of fetal life. We experienced two cases of uterus didelphys complicated with toxemia and are now presenting them in a brief review.

<P><B>Abstract</B></P> <P>The decomposition dynamics of 34 different elements in four different litter types (foliar and woody litter) from <I>Pinus densiflora</I> (Korean red pine) and <I>Castanea crenata</I> (Korean chestnut) was investigated in a cool temperate ecosystem using the litterbag method. Two contrasting trends were observed in the dynamics of elements with accumulated mass loss of litter and carbon. Leaf litter of Korean chestnut, which was richer in elements, showed a general decrease in concentrations of elements with accumulated mass loss of litter and carbon on a dry mass basis during decomposition in the field. Other litter types, with initially lower concentrations of elements, exhibited an increase in concentration on a dry mass basis during field incubation. Highest relative increase in the concentration was noticed for the minor elements, and for the woody litters. Concentrations of major and minor elements increased by factors ranging from 1.07 for antimony (Sb) to 853.7 for vanadium (V). Rare earth elements (REE) concentrations increased by factors ranging from 1.04 for scandium (Sc) to 83.5 for thorium (Th). Our results suggest that litter type plays an important role for nutrient dynamics. Results from principal component analysis for major, minor, and rare earth elements showed grouping of elements and high correlation among them (<I>P</I> < 0.05), which suggests a common source. At both sites, element concentrations were high in the soil, especially for REE. This suggests that increase in element concentrations during field incubation probably was due to transfer of elements from soil to the overlying decomposing litter.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The dynamics of major, minor, and rare earth element was studied in decomposing forest litter. </LI> <LI> Angiosperm and gymnosperm leaf litter showed contrasting patterns of changes in concentrations of the studied elements. </LI> <LI> Rare earth elements showed identical pattern of accumulation in woody litters after one year of decomposition. </LI> </UL> </P>

The occurrence of conjoined twin is very rare and most do not survive. Prenatal diagnosis of conjoined twin is difficult. But early prenatal diagnosis and assessment for shared vital organs are desirable for optimal obstetrical counseling and management. We have recently met two cases of conjoined twins, cephalothoracopagus syncephalus and thoracopagus. So we report these cases with brief review of the literatures.
