BACKGROUND Mass vaccination of dogs is considered fundamental for national rabies control programmes in Sri Lanka, as dog is the main reservoir and transmitter of the disease. METHODS Dogs were followed to determine the sero-prevalence of antibodies to the rabies virus. Altogether 510 previously vaccinated and unvaccinated dogs with owners (domestic dogs) and dogs without owners (stray dogs) ...

Coeliac Disease (CD) is an immune-mediated systemic disorder elicited by the ingestion of gluten. Small-bowel biopsies and histology has been the gold standard for diagnosing CD. The modified ESPGHAN guidelines recommend that in symptomatic children with anti-tissue-Transglutaminase (tTG) titre of > 10 times Upper-Limit-of-Normal (ULN), diagnosis of CD can be made without small-bowel biopsies. ...

The time course of DNA binding capacity (DNA-bc) was found to correlate with the clinical course in a group of 21 patients who had biopsy-proven lupus glomerulonephritis and were treated with immunosuppressive agents. Eight patients showed a sequential DNA-bc pattern in which a high titre of anti-DNA antibody was present for a prolonged period of time all having an unfavourable clinical course....

Using confocal microscopy we have examined in detail the temporal and spatial pattern of green fluorescent protein expression following sub-retinal injection of recombinant adeno-associated virus (rAAV) in the mouse and have determined the effect of viral titre on the number and type of cells transduced. Our results suggest that some transgene expression occurs as early as three days after inje...

The use of a buffer system based on N-[2-hydroxyethyl]piperazine-N'-[2-ethanesulfonic acid] (HEPES), in conjunction with standard Gourlay's culture medium was investigated for the growth and maintenance of Mycoplasma mycoides subsp. mycoides SC vaccine strain T(1)44. When the initial pH of the culture medium was adjusted to 8.0, 0.075 M HEPES-NaOH was found to be sufficient to prevent the pH fa...

Present study was done to evaluate the effect of Ocimum sanctum seed oil (OSSO) on the immunotoxicity and oxidative activity of lindane in rats. Rats were divided into four groups (n = 8) and were treated with lindane (10 mg/kg, po) and/or OSSO (1 mg/kg, po) during the study period. Humoral immunity was assessed by measuring haemagglutination titre to sheep red blood cells (SRBC) and delayed ty...

showed a haemoglobin concentration of 124 g 1; white cell count 2-4x 109/1 (76°,' neutrophils, 20",, lymphocytes, 4",, monocvtes); platelet count 200 x 109 1; sedimentation rate 44 mm in first hour; normal urea and electrolytes and liver function values; antinuclear factor titre positive at 1/1280; rheumatoid arthritis haemagglutination titre positive at 1 80; and double stranded deoxyribonucle...

A larval moult in the tobacco hornworm, Manduca sexta, involves an endocrine cascade that begins with the release of a cerebral peptide hormone, the prothoracicotropic hormone (PTTH). The release of PTTH is gated, occurs during the scotophase and appears to be developmentally cued. In fourth instar Manduca larvae, PTTH release into the haemolymph occurs as a single burst over a few hours during...

AIMS To clarify the relation between the serum titre of anti-Helicobacter pylori (H pylori) antibody and the extent of intestinal metaplasia of the gastric mucosa. METHODS The serum anti-H pylori IgG titres of 95 asymptomatic individuals (mean age 65 years) undergoing an annual health examination were measured and compared with the extent of intestinal metaplasia (absent, moderate, or extensi...

OBJECTIVE The aim of this study was to establish a baseline titre for the population of Mumbai, Maharashtra, India. METHOD Four hundred healthy blood donors, attending blood donation camps, were screened using a survey questionnaire. Widal tube agglutination test was performed on the diluted sera (with 0.9% normal saline) of blood donors, with final dilution ranging from 1 : 40 to 1 : 320. ...
