Centella asiatica is an herbal plant used on different continents by diverse ancient cultures and tribal groups. Historically. the extract has been used as a wound healing agent, The extract has three different triterpenoid ingredients: asiaticoside. asiatic acid, and madecassic acid. It has been reported that its wound healing activity is associated with the modulation of collagen synthesis in the skin dermis. The wound healing property of the extract has led to its commercial introduction under the trade name, Madecrlssol. As part of our program toward the development of new wound healing agents. structere activity relationship (SAR) studies have been performed by modifying asiatic acid. In this communication. the SAR study of esiatic acid for the development of an efficient woind healing agent is reported.

The most common surgical procedure used to manage tracheoesophageal fistula is the primary anastomosis of the esophagus. However, in the case of failed anastomosis, replacing the esophagus with another organ is necessary. We performed two procedures of colon interposition after failure of tracheoesophageal fistula repair. In those cases, stomach replacement was not possible because of a failed Ivor Lewis operation in one case and duodenal atresia in the other.

This is about the successful use of eCG and hCG for producing a Siberian tiger pup born from 10-year-old, primiparous, albino Siberian tiger. From February 2010 to July 2010, natural breeding had been tried three times with no conception. During this period of five months, estrus behaviors appeared to be typically normal and a lot of matings were observed. After consecutive failures, 1000 IU eCG (equine chorionic gonadotropin) were intramuscularly injected on the day showing estrus behavior, followed with an injection of 750 IU hCG (human chorionic gonadotropin) 80 hours later. The tiger stopped recurrence of estrus, and a cub, weighed 780 gram, was born alive 104 days after hCG injection. This study is the first report showing the unique, successful use of exogenous hormones as one of artificial breeding programs in the long history of captive breeding of carnivorous zoo animals in Korea.

Since capsaicin was found as an excellent vanilloid receptor agonist, considerable efforts toward the development of a novel analgesic have been continued. However, the small therapeutic window between these effects and the excitatory side effects, such as hypothermia, bronchoconstriction, increased GI mobility, and hypertension, precluded the development of capsaicin as a systemic agent.

At the University of Seoul, we are investigating the following topics in cosmology: comparing traditional clustering algorithms to our new Mulguishin algorithms, analysis of 2-body Fuzzy Dark Matter 2-body collision, 2- and 3-point clustering statistics and its dependency on the cosmological model, and dynamics of dark-matter halos around the large-scale filamentary structures. In the following sections we present a brief introduction to our studies.

The authors analysed 2,653 cases of transthoracic fine needle aspiration cytology of the lung to evaluate the diagnostic accuracy and its limitation. A comparison was made between the original cytologic and the final histologic diagnoses on 1,149 cases from 1,074 patients. A diagnosis of malignancy was established in 38.3% benign in 48.1%, atypical lesion in 2.3%, and inadequate one in 11.9% of the cases. Statistical data on cytologic diagnoses were as follows; specificity 98.9%: sensitivity of procedure, 76.8%: sensitivity of diagnosis, 95.5%: false positive 5 cases: false negative 18 cases: predictive value for malignancy, 98.8%: predictive value for benign lesion, 79.5%: overall diagnostic efficiency, 87.5%: typing accuracy in malignant tumor, 80%.

Dadohaehaesang National Park is a well-known habitat for a variety of indigenous animals and plants; however, there are no studies on the diversity of macrofungi. To undertake a basic survey of the macrofungi diversity in an unexploited area, we focused on surveying the macrofungi in Dadohaehaesang National Park, Korea, during 2017 and discovered two unrecorded species belonging to the order Polyporales. The two species were identified as Cinereomyces lindbladii and Steccherinum bourdotii based on a combination of morphological characteristics and sequence analysis of the internal transcribed spacer region. We provide macro- and micro-morphological descriptions for these two unrecorded species in Korea.
