Differences among Endophytic Fungal Communities Isolated from the Roots of Cephalanthera longibracteata Collected from Different Sites in Korea

Orchidaceous plants have symbiotic relationships with endophytic fungi, including mycorrhizal fungi, which play important roles in the seed germination and growth of the host plants. In this study, endophytic fungal communities isolated from the roots of Cephalanthera longibracteata collected from three different sites in Korea were analyzed, and it was determined whether fungal communities were preferentially correlated with the sites. The fungal isolates were identified by sequence analysis of the internal transcribed spacer regions of rDNA. In total, 30 species of endophytic fungi, including two species of mycorrhizal fungi belonging to the genus Tulasnella, were identified. Leptodontidium orchidicola showed the highest frequency and was isolated from all root samples. Species diversity and richness were not significantly different among sites. However, the community structure of the endophytic fungi significantly differed among sites, suggesting that the site characteristics affected the community composition of the endophytic fungi colonizing the roots of C. longibracteata. Our findings will aid in developing methods involving the use of symbiotic fungi for orchid conservation and restoration in native habitats.

Anesthetic experience during reconstruction surgery of a chest wall defect in a patient with Poland syndrome: A case report / 대한마취과학회지

Poland syndrome, which is characterized by an absence of pectoralis muscles and their innervated nerves, is marked by variable chest wall defects due to deficits of 2nd, 3rd, 4th, and 5th ribs and costal cartilage. Additionally, there are other reported combined anomalies of the heart, lung, kidney, ipsilateral hand and foot associated with the syndrome. The lung on the side with the thoracic deformity is more hypoplastic or smaller than the lung on the unaffected side, which can cause herniation of the lung or paradoxical ventilatory movement in severe cases, thereby increasing the risk of respiratory depression and hypoxemia. Patients may have profound lung complications due to depressed respiratory muscle function and exacerbation of the underlying chronic pulmonary disease during the perioperative period. These patients also show increased risk of malignant hyperthermia and therefore require careful attention during general anesthesia. We report here an anesthetic experience during reconstruction surgery of a chest wall defect in a male patient with Poland syndrome.

The effects of esmolol, esmolol and nicardipine or remifentanil on mean blood pressure, heart rate and recovery in gynecologic laparoscopic surgery / 대한마취과학회지

BACKGROUND: The purpose of this study was to compare the effects of esmolol, esmolol and nicardipine or remifentanil on MBP, HR and recovery in gynecologic laparoscopic surgery. METHODS: Eighty patients scheduled for gynecologic laparoscopic surgery were randomly allocated to four groups: group C (control group, n = 20); group E (esmolol group, n = 20) received esmolol 1 mg/kg, followed by 5microgram/kg/min; group EN (esmolol + nicardipine group, n = 20) received esmolol 1 mg/kg and nicardipine 15microgram/kg, followed by an esmolol infusion 5microgram/kg/min; and group R (remifentanil group, n = 20) received remifentanil 1microgram/kg, followed by 0.05microgram/kg/min. The MBP and HR were measured at preinduction, after induction, at 1, 3, 5 min after intubation, before and after insufflation of CO2 and during surgical procedures. Recovery profiles and postoperative side effects were assessed. RESULTS: The change of MBP after intubation was significantly decreased in group EN. The change of HR after intubation and during surgical procedure were significantly decreased in group E and group R. Recovery profiles were significantly faster in all study groups compared with group C. CONCLUSIONS: The use of esmolol in combination with nicardipine was effective in preventing the increase of MBP after intubation, whereas esmolol or remifentanil had attenuated the acute change of HR to noxious stimuli. Also the use of esmolol, nicardipine or remifentanil as an adjuvant to sevoflurane-N2O anesthesia in gynecologic laparoscopic surgery had facilitated the recovery.

A Case of Open - lip Schizencephaly

Schizencephaly, first described by Yakovlev and Wadsworth in 1946, is a rare congenital anomaly characterized by gray matter-lined clefts that extend through the entire cerebral hemisphere, from the ependymal lining of the lateral ventricle to the subarachnoid space. Clinically, patients with schizencephaly present motor dysfunction such as hemiparesis, seizures, and variable developmental delay. Absence of septum pellucidum, gray matter heterotopia, polymicrogyria, and hypoplasia of optic nerves were also frequently found to be associated with schizencephaly. We experienced a case of open-lip schizencephaly in a one-day-old male infant with wide, tense fontanel, which was confirmed by MRI.

A Case of Congenital Dislocation of the Knee / 대한주산의학회잡지

Congenital dislocation of the knee is very rare skeletal deformity and was firstly described by Chatelaine in 1822. Since then there have been a few number of case reports and some series discussing the etiology and treatment. The tibia is displaced anteriorly in relation to the femur. It is generally subdassified as simple hyperextention, subluxation, and dislocation depending on the degree of the joint displacement and the severity of disease. Early gentle manipulation and serial splintage or plaster cast are recommended for treatment and were successful in the majority except the case of quadriceps contrarture or late correction. The authors experienced one case of congenital dislocation of the right knee and brief review of the related literatures was made.
