The rotavirus-induced diarrhea of human and animal neonates is a major public health concern worldwide. Until recently, no effective therapy is available to specifically inactivate the rotavirion particles within the gut. Passive immunotherapy by oral administration of chicken egg yolk antibody (IgY) has emerged of late as a fresh alternative strategy to control infectious diseases of the alimentary tract and has been applied in the treatment of diarrhea due to rotavirus infection. The purpose of this concise review is to evaluate evidence on the properties and performance of anti-rotavirus immunoglobulin Y (IgY) for prevention and treatment of rotavirus diarrhea in human and animal neonates. A survey of relevant anti-rotavirus IgY basic studies and clinical trials among neonatal animals (since 1994-2015) and humans (since 1982-2015) have been reviewed and briefly summarized. Our analysis of a number of rotavirus investigations involving animal and human clinical trials revealed that anti-rotavirus IgY significantly reduced the severity of clinical manifestation of diarrhea among IgY-treated subjects relative to a corresponding control or placebo group. The accumulated information as a whole depicts oral IgY to be a safe and efficacious option for treatment of rotavirus diarrhea in neonates. There is however a clear need for more randomized, placebo controlled and double-blind trials with bigger sample size to further solidify and confirm claims of efficacy and safety in controlling diarrhea caused by rotavirus infection especially among human infants with health issues such as low birth weights or compromised immunity in whom it is most needed.

I suis cocciosis in piglets seems to occur in the majority of Korean sow herds. Cocci야osis is characterized by a pasty diarrhea in piglets appearing at 5 to 11 days old. Morbidity is variable, Mortality is usually low but piglets growth is always retarded. And, the principal source of infection is the environment because of the high resistance of oocysts. Control of coccidiosis is usually frustrated since the majority of treatment have not constant results. Mundt et al(1990) developed a new strategy by administrating toltrazuril as an oral suspension. This new anticoccidial drug reduced clinical signs and mortality. Therefore, we will try to medicate piglets with Baycox(Bay Vi 9142) suspension in a sow herd, having a problem of I suis coccidiosis. The incidences of coccidiosis in suckling piglets in C and D bleeding stock farm were from 28.6 to 42.3 and 21.1~57.9 % during 3 to 21 day-old. The body weights of suckling piglets in treated groups were higher than those of control groups at 11 and 18 day-old. Also, those of C breeding stock firm were higher than those of D farm. The body weight gains of suckling piglet of treated groups were higher than those of control groups. Also, those of C breeding stock firm were higher than those of D farm. There was no dead piglet in all experimental groups. Some atrophic piglets were done away with. In C breeding stock farm, the incidences of diarrhea in treatment groups were significantly lower an those of control groups. Also, the degrees of diarrhea in treated groups were significantly lower than those in control groups. In D breeding stock farm, the incidences of diarrhea in treated groups were a little lower than those in control groups. Also the degrees of diarrhea in treated groups were a little lower than those in control groups. In the treated groups, the incidences and degrees of diarrhea were reduced at the 4th day and increased at the 13th day after treatment. The number of litters excreted oocysts in treated groups wert lower than those in control groups after treatment. Also, the OPG in treated groups were lower than those in control groups. According to above results, the effect of Baycox suspension against swine coccidiosis was very good. If we will treat with Barcox suspension swine coccidiosis in swine stock farms, we can get good effects of the improvement of body weight gains and diarrhea and e reduce of excreted costs in faeces.

Purpose : Certain strains of lactobacilli are known to accelerate recovery from acute diarrhea. Lactobacillus reuteri is isolated from human breast milk and a commonly occurring Lactobacillus species with therapeutic potential in acute diarrhea. The purpose of the present study was to investigate the therapeutic effect of L. reuteri in acute diarrhea in young children. Methods : Fifty patients between 6 and 36 months of age hospitalized with acute diarrhea (rotavirus in 40 percent) were randomized into two groups to receive either $10^8$ colony-forming units of L. reuteri or a matching placebo, twice a day for their length of hospitalization, or for up to 5 days. Antidiarrheal drugs were not prescribed to either group. The clinical outcome of diarrhea was evaluated. Results : The mean duration of watery diarrhea after initiation of treatment was 2.3 days for the L. leuteri group(n=25) vs. 2.9 days for the placebo group(n=25)(P=0.072). By the second day of treatment, watery diarrhea persisted in 64 percent of patients receiving L. reuteri, compared to 84 percent of those receiving placebo(P=0.006). On the second day, the mean frequency of watery diarrhea was 1.9 in the L. leuteri group and 3.4 in the placebo(P=0.046). Also, vomiting continued to the second day in 16 percent of patients receiving L. reuteri and 40 percent of those recieving placebo(P=0.031). Conclusion : L. reuteri is effective as a therapeutic agent in acute diarrhea in children.

The aim of this study was to investigate the dietary and lifestyle factors related to bowel pattern of female high school and college students in Gyeonggi Province. The total of 202 self-administered questionnaires (high school students 77 ; college students 125) were analyzed. All respondents were devided into four groups based on their self-reported pattern of defecation: 18 subjects ($9.0\%$) comprised the normal group, 73 ($36.1\%$) the constipation group, 73 ($36.1\%$) the constipation/diarrhea group, and 38 ($18.8\%$) the diarrhea group. Regularity of exercise was significantly higher in the college students than high school students, and times spending on a chair were longer in the high school students than college students. Most students ($72.7\%$) reported that they had stress. Fourty point six percent of the subjects reported that they had 3 meals per day, which tended to be higher in the normal and diarrhea group than constipation and constipation/ diarrhea group. Most students (69.7) skipped breakfast which was lower in the normal group than the other groups. The most preferred dietary fiber food was korean cabbage kimchi. Fifty-eight point four percent of the subjects reported that they had irregular bowel movement. Bowel movement was more irregular in the high school students than college students, and in the constipation group than the other groups. Of the subjects, $77.7\%$ had defecation frequency between three per week and three per day. Those who spent within 10 minutes for defecation were $79.6\%$, and those had difficulty in evacuating were $76.0\%$. High school students and those with constipation and constipation/diarrhea had a significantly lower defecation frequency, longer time spent at the toilet, and greater difficulty in evacuating than college students and normal and diarrhea group. The percentage of those who had feelings of residue in the intestine after defecation was $92.5\%$, and it was greater in the constipation or diarrhea group than in the normal group. Most students ($93.5\%$) reported that they had abdominal pain or discomfort. These results suggest that decreasing times spending on a chair, decreasing stress, keeping 3 meal per day at regular hours, and increasing dietary fiber intake are associated with desirable bowel pattern.

This study was conducted to determine the effective environmental control measures in preventing calf diarrheal disease in farms. It was found that the high numbers of calves in a cow house was directly related with the high incidence rate of diarrheal diseases. When the number of calves was increased in a cow house, it was difficult to reduce the diarrheal diseases of calves. It was revealed that the incidence rates of calf diarrheal disease were dramatically reduced when the delivery house which faced south. The periodical changes of bedding materials seemed beneficial good to control the possible resident infectious agents, including pathogenic viruses and bacteria. The control of the delivery time was important for reduction of calf diarrhea. It was revealed that September and October were the best time as the delivery period. In order to use old cow house as a delivery house, it should be sterilized by the disinfectant and the flame. When the diarrheal feces were removed as soon as possible, the transmission of diarrheal diseases among calves In the same house was reduced. When the diarrheal feces were not disposed, the incidence rate of diarrhea reached up to 50%. When the morbid calves were not quarantined, the incidence rate of diarrhea was 100%. In contrast, when the diseased calves were quarantined from other calves, the incidence rate of diarrhea was reduced, remarkably. The mean recovery time from the diarrhea of the treated calves in the southern cow house was much faster than that in the north cow house. The treatment of calves in a clean and well-ventilated cow house with dry bedding was more effective than that in a cold, wet, and dark house. It could be postulated that the most important environmental factor in the reduction of diarrheal diseases of calves is the blocking of the entry of the infectious agents. The complete sanitation and control of the delivery house in the using farm is more important than building a new cow house, for prevention of calf diarrheal diseases.

The purpose of this study was to report the clinical effects of Korean medicine on a patient who suffered from Early Dumping Syndrome with diarrhea, abdominal pain, anorexia, and insomnia after gastrectomy. The patient was treated with herbal medicine, acupuncture and moxibustion use in combination with Western medicine for 4 weeks. Though anorexia was maintained at a similar level, other clinical symptoms (diarrhea, abdominal pain, and insomnia) were improved after Korean medicine treatment. Therefore, Korean medicine may be effective for treatment of Early Dumping Syndrome after gastrectomy.

In this presented study, we established a method for diagnosis of porcine epidemic diarrhea(PED) by in situ hybridization(ISH), which made distinct progress in diagnostic pathology. We also carried out the retrospective diagnosis through ISH to assume the exact time of the first outbreak and incidence of PED in Korea. The outbreak of PED in Korea reported in 1992. However, since the end of 1980's, some researches of pig-industry have already suspected the outbreak of PED, not transmissible gastroenteritis(TGE). In this experiment, we performed the ISH using 80 formalin-fixed and paraffin-embedded tissues of porcine intestine which were requests for pathological diagnosis from 63 farms whose primary sign was diarrhea from 1984 to 1991. We prepared biotinylated cDNA probe(492base pairs) for ISH by nick translation method and carried out the ISH, using $Microprobe^{TM}$ capillary action system(Fisher $Biotech^R$). We detected PED virus in intestinal mucosa of 2 cases in 1992, 1 case in 1988, and 1 case in 1987. As a result, we assume that the outbreak of PED in Korea have already started since 1987.

Molecular diagnostic techniques have been used to identify porcine epidemic diarrhea virus (PEDV), a causative agent of acute enteritis in swine, but they were difficult to be petformed and time-consuming. To detect PEDV in a rapid and easy way, we developed biotinylated cDNA probe for N gene encoding the nucleoproteins of PEDV. Formalin-fixed and paraffin-embedded tissues from 24 naturally infected pigs were used for the experiment. The ISH produced a positive reaction in all cases. When intestinal tissues were hybridized with PEDV probe, strong signals were seen in the villus enterocytes of the jejunum and ileum. Hybridization signals were also found in the duodenum from one pig and in colon from dnother. In conclusion, ISH with a biotinylated cDNA probe was provided to be a useful diagnostic method for detecting PEDV effectively in routinely processed tissue sections.
