Newborns with ileal atresia frequently present with abdominal distension, bilious vomiting, and failure to pass meconium. Diagnosis is usually established on plain x-ray of the abdomen by the findings of distended small bowel loops and air-fluid levels. In the period of October 1988 to February 1994, 8 patients with congenital ileal atresia were operated and the following results were obtained. 1. Eight patients were comprise of 4 males and 4 females, the ratio of male and female was 1 : 1. 2. Six patients(75%) had been admitted to our hospital during three days of life. 3. Congenital ileal atresia was in 8 cases : Type I in two(25%), Type II in two(25%), Type III a in three(37.5%), Type III b in one(12.5%). 4. There was one premature patient who was small for gestational age. 5. Overall, abdominal distension and bilious vomiting occurring in seven patients, were frequent presenting complaints. 6. Diagnosis was possible with clinical symptom and simple abdomen. 7. Operative treatment was undertaken as soon as the diagnosis was made. In seven cases a primary end-to-end anastomosis was performed after resection of dilated proximal loop. 8. A total of four associated congenital anomalies were found in one patient. 9. Postoperative complications occurred in three cases(37.5%).

The study of bacteriophage began by F.W. Twort in 1915 and the lytic cycle recognized by d'Herellel in 1917. It repeated about the marine bacteriophage containing Vibrio phage by Smith, Spencer and Ju. Authors isolated 2 virulent phages for the pathogenic V. alginolyticus from marine products. These 2 phages were examined their ultrastructure & host-infection by elecron microscopy and in vivo test using skin of rats. V. alginolyticus phages(VAPs) fomed plaques about 0.5 - 0.9mm in diameter and bands 50 - 60% in sucrose density gradient. VAP had 50 - 120nm tail and 40 - 90nm head in diameter. In vivo test, using rat skin, as well as in vitro test VAP had the activity to V. alginolyticus isolated.

Growth under conditions of iron-restriction and the production of siderophore was examined in Vibrio mimicus ATCC 33653. This strain grew and multiplied in the presence of the high-affinity iron chelators ethylenediamine-di (o-hydroxyphenylacetic acid). Chrorne azurol S (CAS) agar and solution were used to detect the production of siderophore under these condition. Siderophore could be detected in the iron-rcstricted culture supernatants. The siderophore was extracted from iron-restricted culture supernatants by phenol-chloroform-ether method and purified by Dowex ion-exchange and Sephadex G-25 gel filtracton chromatography. The purified siderophore was confirmed by paper chromatography and HPLC. The Purified siderophore enhanced the growth of V. mimicus when the bacterium was grown in iron limited medium. Injection of both the siderohore and the bacteria to mice resulted in more rapid death than that of the only bacteria. However, the siderophore did not show lethality to mice and any toxicity to cell line like HeLa and U937.

This review-article is aimed at shedding a light upon the nature of age-associated changes in the human skeletal system. When the anatomical, physiological and biochemical consequences of bone aging are considered together with the hardening, drying and the diminished repair capabilities of the elderly, it can be seen that fractures assume greater importance as a clinical problem in the geriatric population. Older people start out with a deficit of cortical bone, making them more fracture prone and once fractures occur, the necessary treatments (immobilization, use of casts, etc.) accelerate the rate of bone loss. In addition, aged individuals stand a higher risk for complications of the hospital and enforced bed rest that may ensue. The problems resulting from bone loss in the elderly may be partially alleviated by providing adequate health service support which should include consideration of the following points : 1. Age, sex and general health status ; 2. Habits and inclinations towards physical activities ; 3. Nutritional and endocrine background ; 4. Presence of any specific bone diseases, including osteoporosis, osteoarthritis, osteomalacia and ankylosis ; 5. Psychosocial adaptability and other behavioral elements.

A novel bacteriophage, designated as VPP97, that infects the strains of Vibiro parahaemolyticus (hallophilic, Gram-negative bacterium) isolated most commonly from marine environments, has been discovered, and several of its properties have been determined. The plaques were clear and sized 0.6-1.0 mm in diameter. The virion forms a single band on 70% sucrose gradient and p1.50 CsC1 gradient by sucrose gradient centrifugation and CsCI gradient centrifugation respectively. It has a hexagonal head and a relatively long tail, as shown by electron microscopy. Vibrio alginolyticus, Vibrio fluvialis and Vibrio furnissii were also sensitive to this phage It was almost totally inactivated at 70 degree C and at pH below 5 or over 10. The nucleic acid of VPP97 is composed of DNA. The VPP97 had 9 specific structural proteins sized between 21.5 kDa and 97.4 kDa on SDS-PAGE. When V. parahaemolyticus cultures were treated with either phage VPP97 or one of the several antibiotics for 2 hours, the viable number of V. parahaemolyticus treated with the phage VPP97 is lower than that treated with chloramphenicol, erythromycin or penicillin, but not lower than that treated with tetracycline. Mice that have responded to the phage treatment revealed the lower numbers of V. parahaemolyticus in small intestine and less damage on small intestine compared to the untreated mice. Therefore, we suggest that the phage treatment appears effective to the infection by V. parahaemolyticus.

From June to October in 1993~1995, cultured Penaeus chinesis and Penaeus japonicus occurred mass mortality at the farm in Western Sea of Korea. The disease was reproduced in healthy shrimp by injection of filtered (at 0.45 micromeger) homogenate of infected shrimp. So we concluded hat it was filterable agents like virus. Clinical symptoms were white spots on the carapace and reddish tail. Histopathological changes were characterized by hypertrophied nuclei at cuticular epidermis lymphoid organ, hematopoietic tissue. In negatively stained preparation, the virion revealed rod-shaped, enveloped, nonoccluded. Cytopathic effect (CPE) were not observed by virus in CHSE-214, RTG-2, EPC, FHM cell lines. Base on the above facts, the reason of mass mortality of penaied shrimp was baculovirus.

PURPOSE: This study was conducted to analyze the change in the obesity index in girls receiving a gonadotropin-releasing hormone agonist (GnRHa), based on treatment duration, and to aid in nutritional counseling by investigating dietary habits and lifestyle. METHODS: Anthropometric examinations were conducted on 62 girls treated with GnRHa from January 2010 through July 2014. Parents were asked to fill out questionnaires on patient dietary habits and lifestyle. RESULTS: The group taking GnRHa for over 1 year had a higher rate of obesity increase than the group taking GnRHa for less than 1 year, but they had common habits related to obesity, which should be corrected. In addition, 69.2% of the normal weight group taking GnRHa for over 1 year gained weight, and needed more intensive programs, which include physical exercise and nutritional education. Although girls with precocious puberty showed a decrease in the intake of high-calorie foods with nutritional intervention regardless of treatment duration, they still had problems that needed improvement, such as shorter meals and lack of exercise. CONCLUSION: Girls with precocious puberty and their parents should emphasize maintenance of proper body weight, especially when treatment for over 1 year is anticipated. Consistent education in nutrition, ways to increase intensity and duration of physical activity, and the need to slow down mealtimes are important in managing obesity; doctors need to perform regular checkups and provide nutritional counseling.

The objective of this study was to determine the incidence and distribution of root fusion as well as its sexlinkage in maxillary and mandibular molars. One hundred fifty patients who had eight maxillary and mandibular molars (third molars excluded) were consecutively selected for the study subjects. The subjects provided a total of 1200 molars, i.e., 600 maxillary and 600 mandibular molars. A decision about root fusion was made on the radiographic examination. If a molar had one root and/or roots fused at any part in the root surface, it was considered as having root fusion. The results showed that : (1) 14.1 % of the maxillary molars and 5.8 % of the mandibular molars had a fused root, (2) the prevalence of root fusion in the male was 33 % and 56.4 % in the female, (3) 60 % in the male and 48.8 % in the female had bilaterally paired root fusion, (4) the root fusion was most frequently observed in the maxillary second molar position, but none in the mandibular first position in this study. Within limitations of this study, it can be concluded that, in management of molars with a furcation problem, treatment options such as hemisection and root amputation should be chosen after careful evaluation of root fusion. Further studies are needed to investigate a possible relationship between root fusion and periodontal disease progression.

PURPOSE: Ionizing radiations have been reported as an apoptosis initiating stimulus in various cells and it has established that sustained elevations in [Ca2+] can lead to DNA fragmentation by Ca2+-dependent endonucleases, ultimately resulting in apoptotic cell death. The previous experiments have been reported by using primarily thymocytes and lymphocytes and the change of [Ca2+] was measured only by minutes or hours respectively. We need to evaluate [Ca2+] in both several minutes and hours after irradiation of radiation of radiation therapy and verify the apoptotic cells. MATERIALS AND METHODS: We have measured [Ca2+] in human gingival epitheloid cancer cell with 10 Gy irradiation, at minutely intervals and hourly intervals using digitized video-intensified fluorescence microscopy and the fluorescent Ca2+ indicator dye, fura-2. In order to find out that the transient rise in [Ca2+] could induced apoptosis, cells were incubated for 1 hour at 37 degrees C with TdT enzyme, rinsed and resuspended containing fluorescence and observed under a confocal fluorescence microscope. MTT assay was done to determine cell activity and LDH assay was done to determine the amount of necrotic cells. RESULTS: After irradiation, the transient and temporal increasing of [Ca2+] in the KB cells was founded. Though, there was no change in the intracellular [Ca2+] at 30 minutes and 2 hours after irradiation. We could detect of DNA fragmented cells at 4 hours after 10 Gy irradiated cells. There were no significant differences between 4 hour, 1 day, 3 day cells. There were no significant differences in MTT and LDH assay between the irradiated group and the control group after 4 hours and 1 day. Though after 3 days there were differences in MTT and LDH assay between the irradiated group was significantly decreased than the control group, in LDH assay the number of necrotic cell death of the irradiated was higher than the control group. CONCLUSION: In KB cells there were incipient and temporal increasing of the [Ca2+] with 10 Gy irradiation and the apoptosis was founded from 4 hours later which was earlier than seeing of the change of the amount of the cellular ability and necrosis.

Cystic sebaceous adenomas are rare neoplasms that can arise in salivary glands. Among the salivary glands, the most commonly reported location is the parotid gland where it must be differentiated from other intraparotid masses. Unfortunately, its imaging features are not well-known as a result of its rarity. We report a case of cystic sebaceous adenoma that manifested as a gradually enlarging mass within the parotid gland of a 60-year-old man.
