Persistent pupillary membrane ia a congenital anomaly which waa resulted from incomplete atrophy of the fetal vascular arcades and its associated mesodermal tissue derived from the primitive annular vessels. Authors experienced a case (female, 17 years old) of thick persistent pupillary membrane of both eyes which were required complete removal of these membranes under operating microscope. Her corrected vision has improved up to 0.5 (Rt. eye) from 0.1 and 0.7 (Lt eye) from 0.2 without diplopia after operation.

OBJECTIVE: Human papillomavirus (HPV) has been identified more than 100 HPV subtypes. The distributions of subtypes are different according to nations and regions. We analysed subtype of infection with HPV among women who live in Pusan and surburbs of Pusan. We accessed the clinical usefulness of HPV DNA chip test as a supplementary method of Pap smear in the evaluation of cervical lesion. METHOD: This study was undertaken from January 2002 to January 2005 and the samples were collected from the patients who had abnormal Pap smear. We analysed subtypes of 143 positive cases with HPV DNA chip (Biomedlab) test and estimated pathologic reports of 115 patients except 28 patients who had not biopsy. We investigated pathologic results of 54 of 115 patients who had atypical squamous cells / low grade squamous intraepithelial lesion (ASC/LSIL) in Pap smear and examined high risk HPV in 54 pathologic results. RESULTS: The prevalence of HPV subtypes was 42 cases of HPV-16, 20 cases of HPV- 58, 16 cases of HPV-52, 10 cases of HPV-35, 9 cases of HPV-56, 7 cases of HPV-51, 6 cases of HPV-18 in descending order of incidence in high risk HPV group and 3 cases of HPV-6, 3 cases of HPV-42, 2 cases of HPV-34, 2 cases of HPV-43 in descending order of incidence in low risk HPV group. The results of HPV DNA chip test and 115 pathologic reports were estimated by comparative study. A pure infection with low risk HPV group was detected in low grade lesion. Infection with high risk HPV group was also detected in low grade lesion but was mainly detected in high grade lesion. The pathologic results of 54 patients who had ASC / LSIL in Pap smear were 13 patients had above high grade lesion include 2 cases of invasive carcinoma so false negative rate of Pap smear in the detection of high grade lesion was 24%. CONCLUSION: HPV subtypes were detected HPV 16, 58, 52, 35, 56, 51, 18 types in descending order of incidence and prevalence. Mass study and integrated data from larger population and various regions in many hospitals will be needed. And the supplementary use of HPV DNA chip test may provide clinical usefulness because it can reduce the false negative rate of Pap smear and improve the positive predictive value in the detection of high grade cervical lesion and it enables to decrease the incidence of cervical cancer.

A detailed study of the distribution of neuropeptide Y(NPY) in the olfactory bulb of the male adult and aging rat brains was undertaken by means of immunohistochemistry. Adult rats(Sprague-Dawley, 12-14 weeks old) were used in the control group. And aging rats(30 months old) were used in the experimental group. Brain tissues of both rat groups were obtained from each animal which were perfused transcardially with 0.9% NaCl followed by a 4% paraformaldehyde solution. Coronal serial sections(30nm) were cut on a freezing microtome, and were immunostained with the rabbit-raised antiserum to neuropeptide Y. In the control group, neuropeptide Y-immunoreactive(NPY-IR) neurons were mainly found in the white matter and deep internal granule cell layer, and rarely in the external plexiform layer of main olfactory bulb. In case of accessory olfactory bulb, a few of NPY-IR neurons were found in the internal granule cell layer. Virtually most neurons were medium-sized(10-20nm), and appeared to be bipolar or bitufted in shape. And small numbers of large-sized multipolar neurons(20-30nm) were found in the internal granule cell layer of main olfactory bulb. In the experimental aging rats, the numbers of NPY-IR neurons were decreased, that is to say, NPY-IR neurons in aging group were found average 2.5 neurons per each section compared with average 4.5 per each section in the control group. Also many perikarya of NPY-IR neurons appeared shrinkage, oval or round in shape. In brief, NPY-IR neurons of the olfactory bulb seem to be decreased in number of the neurons in aging rat. These findings may concern with reduction of olfactory function.

Traditionally postpartum hemorrhage is a bleeding more than 500 ml that occurs immediately after the placenta is delivered. It remains one of the most common causes of maternal mortality. Morbid adhesion of the placenta is emerging as a major cause of massive postpartum hemorrhage unresponsive to medical therapy. We experienced three cases of major postpartum hemorrhage over 5,000 ml, developed from anterior placenta previa totalis with adhesion of placenta. The hemorrhage had been controlled successfully by compressing abdominal aorta intermittently with the operator's hand during Cesarean hysterectomy. In immediate life- threatening postpartum hemorrhage this simple and safe technique can be used in slowing the bleeding while stabilizing the patient and preparing for definitive treatment.

BACKGROUND: During shoulder surgery, blood pressure is frequently measured at the ankle. Anesthetic complications may result when ankle blood pressure is higher than brachial blood pressure and anesthesiologists misinterpret ankle blood pressure as brachial blood pressure. Therefore, we investigated whether ankle blood pressure is significantly higher than brachial blood pressure before anesthesia induction, during induction, after tracheal intubation, before beach chair position, and in the beach chair position. METHODS: Thirty patients requiring general anesthesia for shoulder surgery were included in this study. Ankle and brachial blood pressure were simultaneously measured before induction, during induction, after intubation, before beach chair position, and in the beach chair position. RESULTS: Ankle blood pressure was higher than brachial blood pressure before induction, during induction, after intubation, before beach chair position, and in the beach chair position. Ankle-brachial blood pressure differences in the beach chair condition were much higher than in four other conditions. The correlation coefficient between mean ankle-brachial blood pressure differences before the beach chair position and mean ankle-brachial blood pressure differences in the beach chair position was 0.616. Brachial systolic blood pressure could be predicted by regression equations (R2 = 0.306-0.771). CONCLUSIONS: These results suggest that anesthesiologists should consider these ankle-brachial blood pressure differences when monitoring anesthesia in the beach chair position.
