It is a fact that there are recent increasing trends of incidence of the colorectal carcinoma among other colorectal diseases. In such trend, the early detection remain to be most important by the air contrast barium enema and total fiber optic colonoscopy There are several ways to prepare the colon for barium enema and fiber optic colonoscopy which include several agents. The mechanical cleansing have been used most frequently since Brown's method was adapted to be most perfect for colon cleansing. The ideal laxatives and enema solutions were limited to adequate dose, it's effectiveness, patient's diet and bowel habit, minimal side effect, low cost and simple to perform. In order to compare the effectiveness of various cleansing solutions, six experimental methods were formed as shown; 1. normal saline enema, 2. castor oil with normal saline enema, 3. castor oil with soapsuds enema, 4. magnesium citrate with normal saline, 5. magnesium citrate with soapsuds enema and 6. ingestion of Golyetly solution. The authors have compared and determined the degree of cleanliness by an experienced endoscopist The total number of patients was 247, age distribution was 43 +/- 15 years old, and sex distribution was 133 males and 114 females. The grade I and II represented no difficulties at performing the fiber optic colonoscopy+, but grade III and IV had some difficulties, even unable to perform the fiber optic colonoscopy. The effectiveness the cleansing agents, represented with grade I and II was 95.9% (47/49) in method 6, 93.2% (54/58) in method 2, 83.3% (30/33) in method 3, 70.0% (28/40) in method 5, 66.7% (16/24) in method 1, and 45.7% (18/40) in method 4. Method 2 and 6 were the most effective in normal bowel habit patients. In constipated patients, method 6 was the most effective and all method except method 4 were effective in diarrhea patients. The degrees of less mucosal irritation by various bowel cleansing method were in the order of method 6(100%), 1(100%), 5(74%), 2(69%). In subjective symptoms and cleansing groups, abdominal distension, pain, nausea and vomiting were complained, and that's subject symptoms were in the order of method 3(88.9%), 6(79.6%), 1(75%), 5(72.5%), 2(72.4%), 4(67.5%). In conclusion, we believe that the Golytely of the mechanical cleansing solution for fiber optic colonoscopy was the most effective, but others depended on the patient's condition and bowel habit.

A 4-day-old foal died with bloody diarrhea. Using a mouse neutralization test, Clostridium perfringens type C was isolated from intestinal contents, and alpha and beta toxins were identified. About 4 m of the jejunum had severe necrohemorrhagic enteritis. Microscopically, large, rod-shaped, gram-positive bacteria were seen on necrotic intestinal villi by use of Brown and Hopp's stains.

Small bowel and its mesentery contain considerable amounts of lymphoid tissue that can mediate graft-versus-host disease in small bowel transplant (SBT) recipients. Present studies determined the existence of GVHD in a fully allogeneic SBT model and examined the effect of donor pretreatment with ALS in eliminating GVHD. Adult male Lewis (Lew) rats received orthotopic small bowel transplants from untreated (LewxBN)F1 (LBNF1) donors (group 1) or Brown Norway (BN) donors that were untreated (group 2) or pretreated with ALS (days -2 and -1) (group 3). All recipients were treated with cyclosporine 15 mg/kg/day i.m. on days 0-6 postoperatively. Animals were weighed and examined daily for signs of rejection and GVHD. No animals in groups 1 or 3 showed any physical signs of GVHD, but all of those in group 2 had characteristic weight loss, diarrhea, and dermatitis between 4 and 6 weeks postoperatively, from which they all recovered. Histologic examination of skin and spleen at this time confirmed the presence of GVHD. The relative spleen weight [( spleen weight/body weight] x 100) of group 2 animals was also significantly greater than that of unoperated control Lew animals. Spleen cells obtained from group 2 animals at the time of subclinical GVHD, but not cells from group 1 or 3 animals, caused enlargement of popliteal lymph nodes when they were injected into the footpads of Lew rats. This study shows that GVHD can manifest itself in recipients of a fully allogeneic small bowel transplant even when rejection is prevented by effective immunosuppression with CsA. However, combined use of recipient treatment with CsA and pretreatment of donor animals with ALS eliminates all manifestations of GVHD.

Five cases of intestinal microsporidiosis are reported, including one case of a heterosexual female acquired immunodeficiency syndrome (AIDS) patient, three homosexual males, and one bisexual male AIDS patients with detailed description of their clinical course. These five cases underscore the severity of immunodeficiency in patients with microsporidiosis. All patients had multiple opportunistic infections and a CD4 cell count below 100/microliters long before diarrhea developed. This is the first kinetic study of helper T-lymphocytes in cases of microsporidiosis. Diagnosis was made by duodenal biopsies stained with Brown and Brenn or Gram-Weigert technique (confirmed by electron microscopy) and by stool smears stained with a modified trichrome technique. However, the best preparation was plastic sections stained with toluidine blue, which demonstrated both the spores and plasmodia clearly. In our evaluation, Giemsa stain was also acceptable for identification of microsporidian spores in both intestinal biopsies and stool smears, but there was a failure to identify the organism on hematoxylin and eosin, acid-fast, periodic acid-Schiff, and Gomeri's methenamine silver stained preparations. Therapeutic attempts using albendazole, metronidazole, octreotide, and zidovudine (AZT) failed to eradicate microsporidia in these patients.

An infection with Septata intestinalis was diagnosed in a 35-year-old AIDS patient without diarrhoea. The diagnosis was based on morphological examinations of a duodenal biopsy specimen. Serum antibodies were detected reacting with spores of Encephalitozoon cuniculi. Spores of S. intestinalis and E. cuniculi stained with Brown Hopps Gram stain showed a red colour (Gram negative) and not a blue/black colour which was described for microsporidian spores in tissue.

Orthotopic left lung grafts from Brown Norway (BN) donors were transplanted to Lewis (LEW) rat recipients which had been treated with a single dose of FK506 10mg/kg body weight intramuscularly on postoperative day 3. Although the lungs were rejected with a median survival time of 7 days, with a range of 6-8 days in the untreated controls, maximum survival was prolonged to 60 days. The major adverse effects of this therapy were reduction of feeding, loss of body weight, and diarrhea. One of the 7 rats died on the 21st postoperative day due to anorexia. The effects of this therapy were investigated by histopathological examination and flow cytometric analysis using monoclonal antibodies against rat lymphocytes: OX-39 (anti-interleukin 2 receptor (IL-2R)) and OX-6 (anti-class II MHC). Histopathologically, the lung allografts showed mild perivascular and peribronchiolar cuffs of mononuclear cells, while marked reduction of the thymic medulla with FK506 treatment was also observed. Flow cytometric analysis of the transplanted lung showed no significant changes. Regarding the thymus, the percentages of positive cells labeled with OX-39 and OX-6 were significantly suppressed after this treatment. In the spleen, the number of OX-6-positive cells significantly decreased. The results using this therapy thus suggest that the suppression of IL-2R and MHC class II expression was systemically maintained for a long time.

Two experiments were conducted to compare the effect of chickens' age on resistance to primary and secondary infections with Ascaridia galli. In Experiment I, three groups, each of 80 female Lohman Brown chickens, aged one day, one month, or four months were compared. Within each group, 54 chickens were infected orally with 500 embryonated eggs and 26 were kept as non-infected controls. Weights were recorded weekly and five chickens in each group were slaughtered every 2 weeks for worm counts. At week 10 post-infection, 17 of the infected chickens and 18 of the controls were challenged with 500 eggs. In a replicate experiment (Experiment II), 35 one-day-old and 53 one-month-old female Lohman Brown chickens were infected orally with 500 A. galli eggs. Weights and fecal egg counts were recorded every week and infected chickens were necropsied every two weeks for determination of the worm burden. Chickens infected at one month of age excreted significantly fewer A. galli eggs when measured at 14 weeks of inoculation. The worms recovered from the one-month-old age group were significantly shorter than those from the chickens infected at one day of age in the first experiment. Worm burden and female fecundity values, however, were not significantly different between age groups in both Experiments I and II. Weight gains of infected chickens were not significantly different from the controls' and only a few chickens exhibited occasional slight diarrhea in both experiments. The results from these experiments demonstrate that the chickens' age only partially influences resistance to A. galli infection.

Changes in values of haemagglutination inhibition (HI) antibody titre, rectal temperature (RT) and total protein (TP) were determined for Shaver Brown chickens infected with Newcastle disease virus (NDV) Kudu 113. The infected chickens came down with Newcastle disease by day 3 post infection (PI). The major clinical signs were depression, greenish diarrhoea, paralysis of legs and wings, opisthotonus and torticolis. Mortality and morbidity were 52% and 1000%, respectively. There were haemorrhagic lesions in the wall of the intestine, proventricular mucosa and caecal tonsils. There were necrosis and mononuclear cell infiltration of the liver, kidney and spleen. There was a significant increase in daily mean HI antibody titres from days 3 to 9 PI. Similarly, significant rise in daily mean RTs were noticed in the infected chickens from days 1 to 13 PI. On the other hand, there was a decrease in daily mean TP concentrations of infected chickens, beginning from day 3 PI, and the lowest concentration of 2.60 +/- 0.15 g/dl was obtained by days 7 and 11 PI. The values of HI, RT and TP for the control chickens were relatively constant during the experiment. The correlation coefficient (r) between HI and RT was positive and highly significant (r = 0.725, p<0.001), while the relationship between HI and TP was negative but highly significant (r = -0.712, p<0.001). It was concluded that NDV Kudu 113 induced increases in values of HI and RT, which occurred concurrently with a decrease in TP concentrations of infected chickens.

Negative staining electron microscopy methods can be employed for the diagnosis of viral particles in animal samples. In fact, negative staining electron microscopy methods are used to identify viruses, especially in minor species and wild animals, when no other methods are available and in cases of rare, emerging or re-emerging infections. In particular, immune-electron-microscopy with convalescent sera is employed to detect etiological agents when there are undiagnosed clinical outbreaks, when alternative diagnostic methods fail due to the lack of immunological reagents and primers, and when there is no indicative clinical suspect. An overview of immune-electron-microscopy with convalescent sera's use in the diagnosis of new and unsuspected viruses in animals of domestic and wild species is provided through the descriptions of the following four diagnostic veterinary cases: (I) enteric viruses of pigs: Porcine Rotavirus, Porcine Epidemic Diarrhea Virus, Porcine Circovirus and Porcine Torovirus; (II) Rotavirus and astrovirus in young turkeys with enteritis; (III) Parvovirus-like particles in pheasants; and (IV) Lagoviruses: Rabbit Hemorrhagic Disease Virus and European Brown Hare Syndrome Virus.

We describe the population demographics, rudimentary measures of reproductive performance, the prevalence of major disease conditions and reason-specific proportional mortality for cattle owned by villagers in 16 dzongkhags (districts) in Bhutan based on the findings of a cross-sectional study carried out between March 2012 and May 2014. The animal health issues that were of concern for livestock owners are also identified. Study households were selected using a stratified, two-stage cluster design. Districts (dzongkhags) formed the strata. Villages within dzongkhags were the first sampling stage and households within villages the second sampling stage. All cattle within each selected household comprised the study population. Questionnaires were collected from 409 households with 1480 standing cattle. A total of 71.0% (95% CI 67.9%-74.1%) of the standing cattle population were female and the median age of cattle was 5 years (Q25 3 years; Q75 7 years). Exotic breeds of cattle (Jerseys, Brown Swiss, and their crosses) comprised 41.4% of the cattle population with local breeds making up the remainder. Although exotic breeds of cattle had a significantly lower age at first calving (median 4 years) compared to local breeds (median 4.8 years) there was no significant difference in the number of calving events per cow for the two breed groups. Diarrhoea was the most prevalent disease condition with 2.8 (95% CI 1.5-4.6) cases per 100 animals followed by bovine enzootic haematuria with 1.9 (95% CI 1.0-3.3) cases per 100 animals. The most frequently cited cause of death was misadventure (proportional mortality 26.2%, 95% CI 15.7%-39.2%) followed by old age (17.8%, 95% CI 9.5%-29.4%). A lack of access to adequate fodder and pasture was the animal health issue that was cited by interviewees most frequently. We provide no evidence that exotic breeds of cattle have superior reproductive performance compared with local breeds. The major cattle health concern cited by interviewees, lack of access to fodder, is likely to contribute to suboptimal productivity and the relatively high incidence of bovine enzootic haematuria in this population. We propose that a prospective cohort study of Bhutanese cattle is warranted to more fully elucidate factors affecting the productivity and longevity of cattle in Bhutan.
