The purpose of this study was to examine the effect of heat generated by rotating bur on the dental hard tissue in vitro. Freshly extracted molar teeth with normal appearance from early 20's male were collected and experimental teeth were divided into 4 groups and the teeth in each group were prepared class I cavity with different clinical procedures as follows. The four methods were. I. 20,000rpm without coolant II. 20,000rpm with coolant III. 500,000rpm without coolant IV. 500,000rpm with coolant Five teeth were reserved intact as a control group. These teeth were longitudinally split into two parts by means of chisel after class I cavity preparation. In a control group 5 parts were boiled in water for 20 minutes and the other 5 specimens were not boiled. All specimens were immersed in 2% methylene blue dye solution and the image of dye penetration was examined and photographed under stereomicroscope. Followings were the results obtained through the study. 1. In control group, dye penetration of the unboiled specimens was increased than with the boiled group. 2. The specimens prepared cavity without coolant showed decreased dye penetration than with the coolant group. 3. 20,000rpm without coolant group showed the least dye penetration. 4. 500,000rpm with coolant group showed similar level of dye penetration to the unboiled specimens from the control group.

Shigella is one of the most prevalent pathogens for the diarrhoeal diseases in the developing countries. One hundered and six strains of shigella were isolated from January 1980 to August 1981 at the dept. of clinical pathology, Han Yang Medical Center. Subgroups of these strains were identified as one strain of S. dysenteriae, 98 strains of S. flexneri and 7 strains of S. sonnei. None of S. boydii was observed. Sex ratio, male to female was 48 to 58. Age distribution disclosed 6 cases under one year, 11 cases one to under 2 years and 21 cases(19.8%) two to under 3 years. Subtotal of 0 to 9 years showed 64 cases(60.4%). Susceptibility for antibiotics of these strains revealed dibekacin 100%, sisomicin 100%, amikacin 98.1%, cefazolin 97.2%, tobramycin 97.1%, gentamicin 95.2%, colistin 93.0%, minocycline 89.6%, kanamycin 83.0%, carbenicillin 18.9%, streptomycin 18.9%, tmp-smz 8.6%, ampicillin 2.8% and chloramphenicol 1.9%. Patterns of resistance to sulfa, streptomycin, chloramphenical and tetracycline have already started at the early part of 1960 decade. Although ampicillin was highly sensitive to shigella at the end of 1960 to the early part of 1970 decade, this study has disclosed high resistance to the strains. New antibiotics such as amikacin, cefazolin, dibekacin, gentamicin, and tobramycin have revealed highly sensitive to these strains, however, multiresistance for those antibiotics will be shown to be prevalent in this country within several years, where it is probably related to the unrestricted sale and use of antibiotics in man.

Background: ABVD (doxorubicin, bleomycin, vinblastine (Vb) and dacarbazine) is the standard regimen in Hodgkin's lymphoma (HL).Vincristine (O) is a mitotic spindle agent like Vb. We aimed to evaluate the efficacy and safety of O as a part of ABOD in HL. Materials and Methods: Patients who had ABOD were enrolled. Stage I-II HL were evaluated for unfavorable risk factors according to NCCN. National Cancer Institute Common Toxicity Criteria was used for toxicity. Results: Seventy-nine HL patients in our center between 2003 and 2007 were evaluated retrospectively. Median follow-up was 54 months. Most of the patients were male in their third decade. Median ABOD cycles were 6 (2-8). Primary refractory disease rate was 17.7% whereas it was 5.1% for early relapse and 5.1% for late relapse disease. Response rates were as 82.3% for complete response, 11.4% for partial response, 5.1% for stable disease and 1.3% for progressive disease. Half of relapsed patients had autologous stem cell transplantation. Estimated 5-year failure-free survival was 71% and significantly longer in early stage patients without risk factors, bulky disease or radiotherapy (RT) (p=0.05, p<0.0001, p=0.02; respectively). Estimated 5-year overall survival was 74% and significantly longer in those who had no RT (p=0.001). Dose modification rate was 5.1% and chemotherapy delay rate was 19%. There were no toxicity-related deaths. Conclusions: ABOD seems to be effective with managable toxicity in HL, even in those with poor prognostic factors.

Background and Objectives : Necortizing fasciitis in the cervical region is a very rare disease with high mortality and morbidity rates. The purpose of this study was to analyze the clinical characteristics, treatment results, complication and prognosis of necrotizing fasciitis patients. Materials and Methods : We retrospectively reviewed the inpatient charts treated for cervical necrotizing fasciitis at our Otorhinolaryngology clinic. We diagnosed necrotizing fasciitis by the clinical findings such as swelling, redness and pain of infected area and necrosis of subcutaneous fat layer and fascia observed during surgery. Twenty such patients were identified and treated from January 2011 to December 2016. Results : 20 adults consisting of 14 male and 6 females with cervical necrotizing fasciitis were diagnosed and treated. The most commonly known associated preceding illness were dental abscess and tonsillitis. The most pathogen was Streptococcus species (12/20), followed by Klebsiella pneumonia (6/20), Staphylococcus species (2/20). The mean duration of hospitalization was 32.2 days (range,14-86). The mean Modified Laboroatory Risk Indicator for Necrotizing Fasciitis (M-LRINEC) score is 7.4 and more than 4 points was eighteen. All patients received parenteral antibiotics and surgical drainage after admission. Conclusions : The reason for the high survival rate in the study was the early diagnosis, as well as the early surgical procedure and antibiotics. After the operation, frequent betadine irrigation could improve the patient's condition and recover without severe complication.

Four hundred and eighty broiler chicks of both sexes were obtained from commercial hatchery (Hubbard) and raised on floor pens. All chicks were allowed free access to food from 0 to 7 and 20 to 56 days of age. At 7 days of age, all broilers were weighed individually, and divided into five groups as follows: 1. feed ad libitum as the control; 2. allowed free access to food 3 days and starved 1 day ($3{\times}1$); 3. allowed free access to food 2 days and starved 1 day ($2{\times}1$); 4. allowed free access to food 1 day and starved 1 days ($1{\times}1$) and; 5. allowed free access to food 2 days and starved 2 days ($2{\times}2$). Broilers were restricted for 12 days (d 7 through 17) of a 56-day trial. Broilers were fed a commercial starter diet (crude protein 23.8% and ME 3,070 kcal/kg) for 21 days, and commercial finisher diet (crude protein 20% and ME 3,160 kcal/kg) from 22 to 56 days of age. Although there was compensatory growth in some groups, (the $1{\times}1$ female group, and the $3{\times}1$ and $2{\times}1$ male grous), its level was not sufficient to achieve normal body weight at market age. There was sexual dimorphism for accelerated growth as well as differences in the ability to achieve a complete compensation of growth to the weight, feed conversion ratio, and body composition of ad libitum chicks. Early feed restriction could be used to reduce production cost because of the lower fed conversion ratio, mortality rate and the amount of starter diet consumed by broilers. The response of chicks to early feed restriction might depend on the degree of feed restriction, the method of feed restriction, duration of feed restriction, and sexes.

This study examined the age-related patterns in body composition cross-sectionally using Segmental bioelectrical impedance analysis(SBIA), specifically its two components, lean body mass(LBM) and body fat mass, in 1,452 men and 1,436 women with an age range of 19 to over 70 years . Mean height of male subjects was 174.1cm at peak in early 20's and was decreased continuously 0.2-0.3 cm every year. Mean weight was greatest between late 20's and 40's, and was decreased quickly in 70's. Body fat mass was increased steadily before 30's and remained thereafter. Because decreasing lean body mass (LBM), percentage of body fat(PBF) increased continuously with aging. Mean height of female subjects was 161.7 cm at peak in 20's and was decreased steadily around 0.2 cm every year and thus an individual's height was decreased approximately 10 cm in their life cycle. Body weight was increased steadily until 50's and then was decreased. Body fat mass was increased continuously and LBM remained constant and thus PBF was increased steadily with aging. SBIA can be used to compare body composition between genders and between ages. In future studies, SBIA could be applied widely to evaluate variations of body composition in subjects with different nutritional problems.

The purpose of study examined of historical changes of western men's nightclothes from middle ages to the modern ages and analyzed functions and features of men's nightclothes. This study presented meaning and importance of men's nightclothes. The method of study researched the many literatures and internet sources. Until medieval age, men slept naked or in a day-shirt. In the 16th century, a nightshirt was worn in bed. A night-cap was usual, in rather more elaborate form, also worn by day in the house, and even outdoors. In the 17th century, nightshirt was elabrated with ruffles and lace. The nightshirts of 18th century, resembled the day-shirt except that it was slightly longer and fuller in cut. The turn of 19th century, men weared nightshirt with a high folding collar, one button and night-cap of jellybag shape. In the early 19th century, nightshirt had a plain turned-down collar, buttoned at the neck. A night-cap with colored tassel was usual. The middle of 19th century, a nightgown was reaching to the ankle. Pyjamas, in the 1890s, were steadily replacing the nightshirt, before long pyjamas had become generally accepted in place of the nightshirt. A pyjamas which preseverved his male dignity by giving him trousers. Man's ingenuity also modified his nigntclothes so that these took on sexual characteristic. In 20th century, the fabrics had become lighter in weight, and the choice of materials wider. By 1930s, nightclothes had become the man's most colorful garment.

Little is known about the gender differences in energetic requirements of goats in early life. In this study, we determined the energy requirements for maintenance and gain in intact male, castrated male and female Saanen goat kids using the comparative slaughter technique and provide new data on their body composition and energy efficiency. To determine the energy requirements for maintenance, we studied 21 intact males, 15 castrated males and 18 females ($5.0{\pm}0.1kg$ initial body weight (BW) and $23{\pm}5d$ of age) using a split-plot design with the following main factors: three genders (intact males, castrated males, and females) and three dry matter intake levels (ad libitum, 75% and 50% of ad libitum intake). A slaughter group included three kids, one for each nutritional plane, of each gender, and all three animals within a group were slaughtered when the ad libitum kid reached 15 kg in BW. Net energy requirements for gain were obtained for 17 intact males, eight castrated males and 15 females ($5.1{\pm}0.4kg$ BW and $23{\pm}13d$ of age). Animals were fed ad libitum and slaughtered when they reached 5, 10, and 15 kg in BW. A digestion trial was performed with nine kids of each gender to determine digestible energy, metabolizable energy and energy metabolizability of the diet. Our results show no effect of gender on the energy requirements for maintenance and gain, and overall net energy for maintenance was $205.6kJ/kg^{0.75}$ empty body weight gain (EBW) ($170.3kJ/kg^{0.75}$ BW) from 5 to 15 kg BW. Metabolizable energy for maintenance was calculated by iteration, assuming heat production equal to metabolizable energy intake at maintenance, and the result was $294.34kJ/kg^{0.75}$ EBW and $k_m$ of 0.70. As BW increased from 5 to 15 kg for all genders, the net energy required for gain increased from 9.5 to 12.0 kJ/g EBW gain (EWG), and assuming $k_g=0.47$, metabolizable energy for gain ranged from 20.2 to 25.5 kJ/g EWG. Our results indicate that it is not necessary to formulate diets with different energetic content for intact male, castrated male and female Saanen goat kids weighing from 5 to 15 kg.
