The objectives in the present study were to evaluate the therapeutic effect of a sodium salts mixture against Salmonella gallinarum infection in broiler. Of this study, sixty broilers at two weeks of age (body weight, $450{\pm}35$ g) were used to estimate the efficacy of a sodium salts mixture (3.25 mg sodium azide, 2.45 mg sodium cyanide, 0.8 g sodium chlorate) against Salmonella gallinarum infection in broiler with drinking water. Broilers challenged with S. gallinarum were administered with ${\times}$ 1(group I) and ${\times}$ 2(group II) sodium salt mixture for seven days, and cecal content samples were collected at the gate of treatment and on 1st, 3rd, 5th, and 7th day after administration. Changes in body weight and cecal shedding of S. gallinarum were monitored during the experimental period. All groups treated with the sodium salt mixture slightly increased body weight compared to control group but there is no significant difference. At 7th day after administration, the number of S. gallinarum in group I and II was significantly decreased compared to control group (p < 0.001). In the hematological and blood biochemical analysis, values of parameters were not significantly different between the treated groups and control group. From results of the present study, the sodium salt mixture had therapeutic effect on S. gallinarum infection in broilers.

The present study was done to investigate the effect of dietary supplemental freezer dry powder fermentation soybean by Bacillus subtilis (natto) on the growth performance and intestinal microflora, prevention of fowl typhoid infection, the uptake of vegetative diet in broiler chickens. The chickens were fed control diet (supplement antibiotics) and fermentation soybean (0.75, 1.5, 3%) diets. A total of 280 one day old broiler chickens with randomly mixed sexes were fed the four diets for 6 weeks. Body weight gain of chicken fed 1.5% fermentation soybean by B subtilis tend to increase higher than the control from 6th week. Chickens fed diets containing 1.5% fermentation soybean by B subtilis had higher intake than those fed the other levels to the 3th weeks, but lower than control from the 4th week to the 6th week. Feed conversion also improved significantly in the supplemental 1.5% fermentation soybean by B subtilis from the 4th week to the 6th week. The number of B subtilis and Lactobacillus spp in the ileum and cecum tend to increase in the supplemental fermentation soybean by B subtilis at 6 week of age, but was not significantly different. In the nutrient digestibility, the feed conversion on the supplemental 1.5% fermentation soybean by B subtilis was better than the control and the weight of drying feces lower than the control. In test of S. gallinarum intramuscular inoculation, reisolation rate of S gallinarum in liver and feces 1.5% the fermentation soybean by B subtilis 75% (liver), 17% (feces) had decreased than the control.

Acquired facial deformities following cancrum oris sequelae manifested variably according to the nature of tissue necrosis. In cases that tissue loss extends over a wide area of the face, or the tissue nature is different due to congenital facial cleft, it is difficult to reconstruct with a single operation. As cancrum oris has virtually disappeared from our country, clinical report of reconstruction is also rare. We report 5 cases of facial deformities following cancrum oris sequelae. Since 1988, five adult patients(4 female and 1 male) were treated by authors. These patients, with an age ranged from 47 to 58 years, all suffered from acquired facial cleft such as facial mutilation, asymmetry. The stages of operation were from 1 to maximum of 5 operations. All surgeries achieved satisfactory results after a long-term follow-up. But one surgery in the case of palatal mucosal flap for the coverage of reconstructed maxilla alveolar bone resulted tissue sloughness, followed by osteomyelitis. Those were debrided and discarded. In conclusion, all sites of deformities were positioned around one of the oral commissures. In their past medical history, they have been suffering from measles, typhoid fever and unknown febrile illness. We diagnosed the acquired facial deformity following cancrum oris sequelae. The reconstruction of acquired facial deformity following cancrum oris sequelae were difficult due to extensive multiple tissue defects. Therefore multiple staged operations were inevitable. The authors reconstructed 5 cases of simple and complex form of facial deformity with minimum staged operations. All patients were satisfied functionally and cosmetically.

On account of the recent improvement in performance of brown layers, the market share taken by brown layers has increased to about 50% in the world and to almost 100% in Korea. There are several other reasons why the industry has moved from white to brown, such as : brown layers are used to be more robust, more docile and easier to manage ; e brown layers are easier to sex at the hatchery ; brown layers lay less second grade eggs, due to a better shell Quality ; brown eggs seem to be more attractive than white ; and a clear consumer preference, thus a better price per egg. More recently, however, the trend towards brown eggs has been slowing down. The main reasons for this lie in that white layers can still produce an egg at a lower cost and that white eggs have better de-shelling properties, easier candling and higher yolk and solid content of the liquid egg which are benefits for egg processing industry. Although the performance of the brown layers is still improving, there are increasing opinions in the poultry industry that the market portion of white layers should be increased based on the following reasons, such as : shell color has no effect on the nutritive value of eggs ; . brown layers consume more feed ; the percentage of meat spots is significantly higher in brown eggs than in white eggs ; . brown layers are less efficient in the second cycle of production than in the first ; white layers are more resistant to the disease of fowl typhoid. In order to increase the market share of white layers in Korea, it may be needed to enlighten the consumers not to prefer the brown and large eggs and to inform the excellencies of white eggs widely.

담낭암은 조기에 진단되지 않아 예후가 아주 나쁜 소화기암 중의 하나로, 담낭암 발생의 위험성을 예견한 담낭절제술의 대상을 정확히 규명하는 것이 중요하다. 담낭 용종의 크기, 개수, 담석의 유무, 환자의 나이가 담낭암 발생과 관련된 인자이며, 용종 크기 1 cm 이상, 동반된 담석증, 50세 이상, 증상이 있을 때, 관찰 기간 중 급격한 크기 변화가 있을 때 수술을 권하는 것이 좋을 것으로 판단되며, 췌담관 합류 기형이 발견되면 담낭을 반드시 절제 하여야 하며 수술 전 및 수술중 담낭암의 존재 여부를 세밀히 조사하는 것이 좋겠다. 만성 담낭염에서 보이는 담낭 점막의 화생 변화는 전암 병변으로 생각이 되며, 담낭염의 변종으로 생기는 황색육아종성 담낭염, 도재담낭 및 담낭 장관루 등에서 고빈도로 담낭암이 발생하고 있어, 염증성 변화 및 이의 지속되는 기간과 암 발생과는 밀접한 관계가 있을 것으로 사료 된다.

Clostridium perfringens, Salmonella thyphimurium and S. Montevideo isolated from the intestines of dead broiler chickens in Korea were tested for antibacterial effects to purifed bee venom. Purified bee venom from Apis mellifera L. has been used as natural antimicrobial compounds in pigs, cows, dairy cattle and chicken farms in Korea. To investigate antibacterial effect of purified bee venom was evaluated by agar well diffusion method, minimum inhibitory concentraion (MIC), minimum bactericidal concentration (MBC), and postantibiotic effect (PAE). Purified bee venom exhibited significant inhibition of bacterial growth of C. perfringens, S. thyphimurium and S. Montevideo with MIC value of 0.85, 0.68 and $0.69{\mu}g/mL$, respectively. The MBC value of purified bee venom against C. perfringens, S. thyphimurium and S. Montevideo were 3.33, 2.66 and $2.86{\mu}g/mL$. Furthermore, the results of PAE values against C. perfringens, S. thyphimurium and S. Montevideo showed the bacterial effect with 3.5, 4.0 and 3.5 hr. Stability of pufifed bee venom at acidity from pH 1 to pH 8 for 24 hr was the antibacterial activity for C. perfringens, S. thyphimurium and S. Montevideo and melittin contents. Also purified bee venom processed through the heating for 15 min, there was no signification loss of the antibacterial activity and melittin at below $100^{\circ}C$. These results obtained in this study suggest that purified bee venom might be utilized as a feed additive in poultry diets.
