The chromosome study was performed in some species on the Korean Libellulidae by using squash techniques and lactopropionic orcein stain in order to define species relationship between them. The numerical and morphological differences were shown in the chromsome between the species of the stages of spermatocyte metaphase. The results obtained were summarized as follows: 1. The pattern of standard chromosome number in these species is divided into two groups; Orthetrum albistylum speciosum (UHLER), Orthetrum triangrlare melanina (SELYS), Rhyothemis fulignosa HAGEN are 13 in the haploid chromosome number. But, Crocothemis servilia servilia DRURY and Synoetrum eroticum (SELYS) are 12. 2. The shape of chromosome in these specie in divided into two groups; O. albistylum, S. eroticum eroticum, R. fulignosa, O. triangulare melania are bar or clover in shape at the spermatocyte metaphase. These species seem to be holocentric chromosome. On the other hand, C. servilia servilia is gloval and this species has monocentric chromosome. 3. The sex chromosome of five species ( O. albistylum speciosum, O. Triangulare melania, R. fulignosa, C. servilla servilia, S. eroticum eroticum ) are XO type. 4. Three species ( O. albistylum speciosum, O. Triangulare melania, S. eroticum eroticum ) shows the fragment chromosome in the spermatocyte metaphase. As the results, five species on the Korean Libellulidae (O. albistylum speciosum, O. triangulare melania, R. fulignosa, C. servilla servilia, S. eroticum eroticum ) is similar to each other in the external morphology, But, in the analysis of chromosome, these species is different to some degree.

Stromal CD10 was detected in 49.5% (50/101) of the IDC. No immunoreactivity was identified in the stromal cells of normal breast, DCIS or intraductal components of IDC. Accumulation of the cytoplasmic &bgr;-catenin was found in 87.0% (87/100) of the IDC. Stromal CD10 expression in IDC was significantly correlated with tumour size (<I>P</I> = 0.027), stage (<I>P</I> < 0.001) and histological grade (<I>P</I> = 0.006), the presence of nodal (<I>P</I> = 0.048) and distant (<I>P</I> = 0.015) metastases, oestrogen receptor-negative status (<I>P</I> = 0.016), cytoplasmic &bgr;-catenin accumulation (<I>P</I> = 0.031) and lower overall survival rate (<I>P</I> = 0.041).</P><P>Conclusions: </P><P>Stromal CD10 expression in IDC may constitute an important prognostic marker.

Background: When performing reduction of zygomatic arch fractures, locating the inward portion of the fracture can be difficult. Therefore, this study investigated the discrepancy between the locations of the depression on the soft tissue and bone and sought to identify how to determine the inward portion of the fracture on the patient's face. Methods: We conducted a retrospective review of chart with isolated zygomatic arch fractures of type V in the Nam and Jung classification from March 2013 to February 2022. For consistent measurements, a reference point (RP), at the intersection between a vertical line passing through the end point of the root of the ear helix in the patient's side-view photograph and a transverse line passing through the longest horizontal axis of the external meatus opening, was established. We then measured the distance between the RP and the soft tissue depression in a portrait and the bone depression on a computed tomography (CT) scan. The discrepancy between these distances was quantified. Results: Among the patients with isolated zygomatic arch fractures, only those with a fully visible ear on a side-view photograph were included. Twenty-four patients met the inclusion criteria. There were four types of discrepancies in the location of the soft tissue depression compared to the bone depression: type I, forward and upward discrepancy (7.45 and 3.28 mm), type II, backward and upward (4.29 and 4.21 mm), type III, forward and downward (10.06 and 5.15 mm), and type IV, backward and downward (2.61 and 3.27 mm). Conclusion: This study showed that discrepancy between the locations of the depressions on the soft tissue and bone exists in various directions. Therefore, applying the transverse and vertical distances measured from a bone image of the CT scan onto the patient's face at the indicated RP will be helpful for predicting the reduction location.
