It is generally recognized that high stocking density can increase the risk of immune dysfunction and reduction in productivity cause of elevated stress in broiler farm. The domestic livestock industry is implementing a certification system for animal welfare and livestock farms to reduce the problem of dense breeding. This study compared broiler from the general farm and animal welfare farm to confirm the effectiveness of animal welfare farms against stress. Gas concentrations in a farm of general and animal welfare farms were analyzed, blood (n=10) of the 28-day-old broiler was collected, the partial pressure of the gas in the blood was analyzed using whole blood, and biochemical factors and hormones were analyzed using the serum. Glycogen and L-lactate are analyzed using ELISA kit on finely pulverized muscles (n=10). CO₂ and NH₃ levels in the farm were significantly higher in general farm. Partial carbon dioxide tension (PCO₂) in blood was significantly higher and partial oxygen tension (PO₂) was significantly lower in the general farm. Creatinine (CREA), glucose (GLU), aspartateaminotransferase (AST), and creatinekinase (CK) in the blood were significantly higher in the general farm, and total protein (TP) and globulin (GLOB) were significantly higher in animal welfare farm. Blood corticosterone and norepinephrine were significantly higher in general farm and epinephrine was significantly higher in animal welfare farm. These results imply that animal welfare farm provides a stress-reduced breeding environment.

Global warming is a key challenge subjecting animals to heat stress conditions resulting in multiple physiological alterations in tropical climate. Dietary approach seems to be the more friendly approach to curb the adverse effects of heat stress in rabbits. Some herbs have been categorized to have high potential for promotion of immune responses for amelioration of heat stress. Thus, this research aims to evaluate the potential of Mistletoe (Viscum album), Moringa (Moringa oleifera) and Phyllanthus (Phyllanthus amarus) leaf meal as herbal supplements for the alleviation of heat stress in female rabbits by measuring improvement in sex and stress hormonal responses in serum biochemistry. 80 Rabbit does were exposed to 4 dietary groups supplemented with each of Mistletoe, Moringa, Phyllanthus and a control in an 84-day trial at the summit of thermal stress in South west Nigeria. Growth indices were monitored throughout the study, blood samples were compiled at the end of the trial to assess serum biochemistry, stress and sex hormonal responses of the Does using standard protocols. The results revealed that final weight and weight gain of Does fed on Phyllanthus were significantly (p < 0.05) higher (11.46% and 14.25%, respectively) than Does on control. The herbal supplements enhance glucose, protein, albumin and globulin, reduced cholesterol, and creatinine of Does under heat stress conditions. Among the herbal treatment groups, mistletoe, moringa and phyllanthus had 12.42%, 18.39% and 16.90%, respectively, lower corticosterone than control groups which had 39.76ng/ml. Triiodothyronine of Does fed control were significantly (p < 0.05) lower than Does on Moringa oleifera and Phyllanthus amarus supplements. Estradiol and Follicle stimulating hormone of rabbit Does fed on moringa supplement were significantly (p < 0.05) higher than other treatments. In conclusion, the herbal supplements tend to mitigate the detrimental outcome of thermal stress on Does by suppressing stress hormones. Moringa oleifera and Phyllanthus amarus enhanced sex hormones while Phyllanthus amarus confered growth promoting effects on the Does.

Background: Allergic rhinitis(AR) is a heterogeneous disorder that despite its high prevalence is often undiagnosed. It is characterized by one or more symptoms including sneezing, itching, nasal congestion, and rhinorrhea. And it is frequently accompanied by symptoms involving the eyes, ears, and throat, including postnasal drainage. There are many different causes of rhinitis in children and adults. Approximately 50$\%$ of all cases of rhinitis are caused by allergy. In the case of rhinitis caused by allergens, symptoms arise as a result of inflammation induced by a gamma globulin E-mediated immune response to specific allergens such as pollens, molds, animal dander, and dust mites. The immune response involves the release of inflammatory mediators and the activation and recruitment of cells to the nasal mucosa. AR is similar to 鼻？, hypersensitive rhinitis in Oriental Medicine. I think hypersensitive rhinitis is including of AR, vasomotor rhinitis and non-allergic rhinitis related with eosinophil increased and so on. Purpose: To perform a clinical analysis of hypersensitive rhinitis including allergic rhinitis and estimate the efficacy of Oriental Medical treatment. Objective: We studied 96 patients who had visited our hospital with complaints of nasal symptoms from March 2000 to February 2002; they had the signs more than 2 - nasal obstruction, watery discharge, sneezing and eye or nasal itching. Parameters Observed & Methods: We treated them with acupuncture & herb-medication. Sometime they used aroma oil or external medicine. 1) the distribution of sex & age groups 2) the clinical type based on duration & the severity of symptom 3) the breakdown of complication & pasl history of Otolaryngologic or allergic disease 4) the clinical assessment and classification of rhinitis(sneezers and runners & blockers) 5) the associated symptoms and signs 6) the classification of Byeonjeung 7) the classification of prescriptions and 8) the efficacy of treatment. Result: 1. In the clinical type of based on duration, the intermittent type was 42.7$\%$ and the persistent was 57.3$\%$. 2. We observed the severity of symptoms based on the quality of life. The mild type was 24.0$\%$ and the moderate-severe was 76.0$\%$. 3. In the clinical assessment and classification of rhinitis, the sneezers and runners type was 69.8$\%$ and the blockers was 30.2$\%$. 4. The most common family history with otolaryngologic or allergic disease were allergic rhinitis(17.7$\%$), urticaria, paranasal sinusitis and T.B.(3.1$\%$). 5. The most common past history with otolaryngologic or allergic disease were paranasal sinusitis(14.6$\%$), atopic dermatitis and asthma(8.3$\%$). It was 31.3$\%$ they had a family history and 44.8$\%$, past history. 6. The most common complication was paranasal sinusitis(15.6$\%$). In decreasing order the others were otitis media with effusion(9.4$\%$), GERD and headache(6.3$\%$), asthma, bronchitis, nasal bleeding and allergic dermatitis(5.2$\%$). 7. Classification through Byeonjeung : ⅰ) 39 cases(34.9$\%$) were classified as showing Deficiency syndrome. The insuffficiency of Qi was 17.7$\%$, deficiency of Kidney-Yang, 12.5$\%$ and Lung-Cold, 10.4$\%$. ⅱ) 57 cases(59.4$\%$) were classified as showing Excess syndrome. The Fever of YangMing-meridian was 35.4$\%$, Lung-Fever, 24.0$\%$. 8. The efficacy of treatments showed: an improvement in 22cases(22.9$\%$); an improvement partly in 24 cases(25.0$\%$); no real improvement or changes in 16 cases(16.7$\%$); and couldn't check the results 18cases(18.6$\%$). Conclusion: We suggest that this study could be utilized as a standard of clinical Oriental Medical treatment when we treat hypersensitive rhinitis including allergic rhinitis.

Purpose: This study analyzed a small outbreak of measles at a single hospital located in northern Gyeonggi-do in 2013. Methods: We reviewed the medical records of measles patients at The Catholic University of Korea Uijeongbu St. Mary's Hospital from August to October, 2013. Results: Fifteen children were confirmed to have measles by RT-PCR and serum IgM test; 1 neonate, 11 infants, and 3 toddlers. None of the patients had received Measles-Mumps-Rubella vaccination. All patients showed B3 type in viral genotyping. Nine children (60%) had been exposed to measles during treatment for other diseases in the pediatric ward. Incubation period was between 8 and 15 days. Fever started at a median 10 days after exposure and persisted for a median of 8 days. Rash showed at a median 13 days after exposure. Respiratory complications were observed in 40% of patients. Diarrhea developed in 53% of patients. Conclusion: Although measles has been well-controlled due to the high rate of vaccination coverage, it is possible to have an outbreak at any given time, especially in infants. We must learn from this outbreak, and remain fully aware of the possibility of reemergence and provide proper management, including vaccination or immune globulin administration, to infants exposed to measles. Reevaluation of serum IgG titer of neonates, infants, and pregnant women may be the first step to prevent further outbreaks.

The purpose of present study was to investigate the possibility to immunize guineapigs and swine against Metastrongylus apri infection by the administration of irradiated infective larvae. Four main experiments were undertaken. Firstly, three groups of infective larvae irradiated at $3{\times}10^4r$, $4{\times}10^4r$, and $5{\times}10^4r$ respectively were inoculated to guineapigs and their immunogenic effects were examined from the clinical, anatomical, and serological viewpoints to decide the optimal dose of X-ray for the atenuation of them. Secondly, the migratory behavior of the larvae irradiated at the optimal dose was compared with that of normal infective larvae. Thirdly, pigs were inoculated with each 5,000 infective larvae irradiated at the optimal dose and the clinical, anatomical and serological responses of them before and after challenge were examined. Fourthly, the heated extract of adult M. apri which had been used as an antigen in the serological examinations was analyzed and compared with that of adult Ascaris suis and of adult Trichuris suis by immunoelectrophoretic method. The results obtained are summerized as follows: 1) The optimal dose of X-ray for the atenuation of the infective larvae which can minimize the pathogenecity but keep the antigenecity of the infective larvae was $5{\times}10^4r$. 2) Guineapigs could become completely resistant to subsequent challenge infection by the administration of 1,000 infective larvae irradiated at $5{\times}10^4r$, without showing any symptom of disease before and after the challenge. 3) There were some indication that guineapigs could acquire complete immunity after they overcome the infection with normal infective larvae. 4) It was shown that, in guineapigs, the $5{\times}10^4r$-irradiated larvae can migrate to the large intestine and mesenteric lymph node within a day, where they stay for as long as 16 days to stimulate the host's immunity. 5) It also was shown that, in guineapigs, the normal infective larvae challenged to resistant guineapigs can migrate to the large intestine and mesenteric lymph node, where they are affected by the immune mechanism of host within 10 days without further migration. 6) Pigs could become partially resistant to subsequant challenge by the administration of 5,000 infective larve irradiated at $5{\times}10^4r$; no clinical symptom occurred after the administration, but milder symptoms of parasitic bronchitis were observable after the challenge infection and fewer number of worms were detected from the lungs at autopsy compared with severe symptoms and much number of worms in control pigs. 7) It was shown that, in pigs, a few of the $5{\times}10^4r$-irradiated larvae can migrate to the lungs, where they stay for as long as 104 days in stunted and sterile states; their body-lengths were short and their uteri developted no eggs. 8) There was evidence that the male larvae were more susceptible to X-ray than the female larvae. 9) Antibodies relating to the administration with $5{\times}10^4r$-irradiated or normal larvae were detected from the sera of both guineapigs and pigs by means of indirect haemagglutination and agar diffusion precipitin tests. Relatively higher antibody titers were recorded by the former test, but precipitin bands were demonstrable only when the positive sera were concentrated in one tenth of original volume in the later one. 10) The antibody titers of pig sera began to rose on 14 days, kept their peak during the period from 14 th day to 21st day, and fell to a low level on 28 days after the administration of $5{\times}10^4r$ or normal infective larvae. 11) A slight increase in gamma globublin of the pig sera occurred following the administration. The gamma globulin level showed a tendency to fluctuate in acordance with the antibody level. 12) A marked eosionophilia occurred in pigs on 7 or 14 days following the administration. The eosinophil count showed the same tendency to fluctuate as the gamma globulin did. 13) It was shown that the serum antibodies detected by the heated extract of adult Metastrongylus apri react crossly with the heated extract of adult Ascaris suis but not with that of adult Trichuris suis in indirect haemagglutination and agar diffusion preciption reactions. 14) The heated extract of adult Metastrongylus apri could he divided into 9 antigenic components by immunoelectrophoresis, one (arc 4) of which was shown to be common to both extracts of adult Ascaris suis and adult Trichuris suis, and the other one (arc 9) to only the extract of adult Ascaris suis.

Purpose : To determine wether varicella can be prevented by administration of oral acyclovir(ACV) during the incubation period of the disease. Methods : Starting 9 days after exposure to the index case in their families, ACV(40 mg/kg/day in four divided doses) was given orally to 20 exposed children for 5 days. Their clinical features was compared with those of 20 control subjects. Antibody titers to VZV were measured in both group 1 week and 4 weeks after finishing the oral ACV administration. Results : The mean age of family members with varicella(51.4 months) were significantly high compared to that of ACV prophylaxis group(28.5 months) and control group(31 months) (P<0.05). Among the 12 children with ACV prophylaxis who completed follow up blood sampling, nine children were diagnosed as VZV infection on the serologic test(75%). Among them six children showed positive VZV IgM on the first blood sample and two children showed serocoversion to positive IgM on the second test after ACV prophylaxis. One child who was negative on both IgM and IgG, showed positive IgG on the second test. The incidence of fever and severity of skin rashes were significantly low in children received oral ACV than in the control group. No or reduced number of maculopapular eruption were observed in the oral ACV group compared to multiple vesicles of the control group. Conclusion : In the present study, we observed that oral ACV prophylaxis to the family contacts is effective in reducing severity of skin lesion. It is likely that oral ACV 9 days after contact prevents or reduces blood dissemination of VZV. Little is known about clinical effect and immunity to the virus in exposed children with no varicella symptom after treatment. We propose the checking up antibody to VZV some period after oral ACV, and considering vaccination to whom with no antibody. But further more studies are needed to practical application of oral ACV for the postexposure prophylaxis of varicella.
