In order to estimate the tooth-age by degree of attrition, the author has studied 605 stone models from 1996 to 1997. All of the attrition were classified and analyzed by 8 degrees. The result were as follows : 1. The degree of attrition in male was higher than that in female for same age group and especially, canine and first premolar showed the most prominent difference in sex. 2. The most severe attrition in posterior teeth was first molar followed by second molar, first premolar and second premolar in decreasing order of sequence. 3. The coefficient of correlation and relation equations by the degree of attrition were obtained.

The effect of topical application with androstenedione on economic parameters was analyzed following treatment of last larval stadium. The treated larvae showed significantly increased larval weight along with other enhanced larval, cocoon and adult parameters. The larval period was significantly shortened in all the treated groups with increased cocooning percentages cocoon weight and its shell weight in female and filament length, weight and denier in all the treated groups. Hatching percentage increased significantly in dose dependent manner in all the treated groups when compared with the corresponding parameters of the carrier control group. This suggests that androstenedione can be used effectively for commercial silkworm rearing.

Biliary ascariasis is still the leading cause of surgical complication of ascariasis, though its incidence has been dramatically reduced. Herein, we report a case of biliary ascariasis for the purpose of enhancing awareness of parasitic infections as a possible cause. A 72-year-old male visited the emergency room of Dankook University Hospital on 12 July 2015, complaining of right-upper-quadrant pain. By endoscopic retrograde cholangiopancreatography (ERCP), a tubular filling defect in the right hepatic duct was detected. The defect was endoscopically removed and diagnosed as an adult female of Ascaris lumbricoides worm, of 30 cm length. Upon removal of the worm, the pain subsided, and the patient was discharged without any complication. When treating cases of biliary colic, physicians should not neglect biliary ascariasis as the possible cause.

The mortalities of the monkeys that have been raised in Everland Zoological Gardens within a designated period (1976-1999) were retrospectively analyzed based on the clinical charts and/or autopsy reports. During that period, a total of 161monkeys from 8 species were died. Noninfectious and traumatic factors, respiratory and digestive disorders account for the majority of cause of death. 62% of the death was concentrated in the winter season. The mortality of female and male was 53 and 47%, respectively. The mortality of adult monkey(62%) due to neoplasia and senile changes.

Congenital coronary arteriovenous fistula is uncommon disease, and was first described by Krause in 1865. About 20% of the cases, it associates additional congenital heart diseases. A 5-year-old female patient was diagnosed as coronary AV fistula with VSD, and was taken surgical correction under cardiopulmonary bypass. VSD was small and subarterial in type, and the fistula was dilated as adult thumb tip size at its distal portion. VSD was closed directly through the pulmonary arteriotomy and the aneurysmal dilation was opened vertically, then it was obliterated using 5-0, 6-0 prolene continuous suture fashioning into a long slender tube. Postoperative course was uneventful.

A surgical correction was successfully performed in a adult female who had pulmonary atresia with almost non-confluent pulmonary artery, PDA and ventricular septal defect. Initially as a first stage of corrective surgery isolation of patent ductus arteriosus, ligation of aortopulmonary collaterals and identification of the pathologic anatomy of left pulmonary artery through left posterolateral approach were performed. At the second stage, a week after the initial operation, total correction was done making both pulmonary arteries confluent with albumin coated woven-dacron graft, external valved conduit and closure of large VSD of subarterial and perimembranous type. The PDA was ligated with previously encircled heavy stitch soon after partial bypass was started. Although massive bleeding from anastomotic site of dilated left pulmonary artery to the graft occurred preoperatively, postoperative functional improvement was excellent in terms of disappearance of cyanosis and normal exercise tolerance.

Mesothelioma is a primary tumor of the pleura. There are two forms of mesotheliomas; diffuse form and localized form. The majority of localized mesotheliomas are benign, but the tumor with pedicle recur at 20% after removal of it. Malignant localized fibrous mesothelioma is differential diagnosed pathologically and clinically with diffuse mesothelioma. Symptoms of localized mesothelioma are generally related to the size of the tumor. We presented one case of malignant localized fibrous mesothelioma. The patient was 32 years old female and chief complaints were dyspnea and dry cough. Sputum cytology and needle lung biopsy were not able to diagnose definitely the tumor. Explothoracotomy was carried out for definite tissue biopsy. At the time of operation, huge adult head size mass was in the right thoracic cavity. The surface of the mass was nodular, multilobular and had hard consistency. Pedicle was formed above first rib and its diameter was 4.5cm. There was no adhesion except to RUL. Frozen biopsy suggested mesothelioma. Extirpation of the mass, right upper lobectomy. and partial pleurectomy were carried out.

The chloroform extract of the seeds of Carica papaya has been screened for the hormonal properties using ovariectomized female rats for estrogenicity, estrogen primed immature rats for progestogenicity and castrated adult male rats for androgenicity. The results revealed that the extract lacks progestogenicity and androgenicity as evident from the failure of the extract treated animals to mimic progestogen and androgen related changes in the target tissues. The increased weight of vagina and uterus, open status of vagina, cornified and epithelial cells in the vaginal smears and hypertrophy in the uterine epithelium, endometrium and stroma with increased glycogen and sialic acid content in the uterus of the chloroform extract treated animals, which are comparable to those of the ovariectomized estrogen treated animals, suggest that the chloroform extract possesses mild estrogenic activity.

The present study is to develop the rearing method of Gryllotalpa orientalis. In total 429 of G. orientalis were collected from the field rearing cage ($25m^2$) in 2012. Its sex ratio was 1: 1.15(Female : Male). Survival rate of the mole crickets was 94.4~86.1% with the artificial diets formulated for the present study. Successful oviposition rate was 20, 20 and 80% for one, two and three pairs of adult crickets, respectively, from the indoor rearing. The mean number of hatchlings was $11.8{\pm}21.7$, $15.7{\pm}26.4$ and $25.8{\pm}38.8$, and the mean number of dead hatchlings 1.2, 1.7 and 1.2. The mortality of nymphs on horticultural soil and clay sand mixed with ocher was 18.3 and 10.0%, respectively. The mortality of nymphs in circular and rectangular cages was, respectively, 60 and 40%.

Many mediastinal masses seen radiologically are clinically asymptomatic. Only 55 to 65 percent of such lesions are asymptomatic, and of these many have only nonspecific symptoms by rupture, infection and pressure of surrounding organs. This report presents one case of a mediastinal teratoma which complicated an empyema. The patient was 7-year-old female and chief complaints were fever, left chest pain and general ache. In her past history, lung decortication and drainage procedure under the diagnosis of an empyema were carried out, 5 years ago, but she had not been improved, And so, explothoracotomy was done. At the time of operation, a mass of adult fist size was placed in the left anterior mediastinum and covered with the mediastinal pleura. Extirpation of the tumor and decortication were carried out and the left lung was remained.
