The serological responses and protection of Sonali breed chickens with Australian Newcastle disease V4 heat resistant (NDV4HR) live freeze-dried vaccine (Australian Webster Pvt. Ltd., Sydney) was compared with that of locally produced conventional Lentogenic F-strain Baby Chick Ranikhet Disease vaccine (BCRDV, DLS, Dhaka) of Bangladesh. Thirty day-old chicks were purchased from Mirpur Govt. Poultry Farm, Dhaka and maintained hygienically with commercial feed and water supply ad libitum during the experimental period from November 2002 to January 2003. These birds were divided into three groups (A, B and C), each consisting of 10 birds. Each birds of group A was vaccinated with NDV4HR and group B with BCRDV intraocularly, primary vaccination at 7 days and booster vaccination at 28 days of age, whereas the birds of group C kept as control. Sera samples of each of the bird of all the three groups were collected at 14 days of post-vaccination following each of the primary and booster vaccination at 23 and 44 days of age of birds. Each of the serum sample of all the three groups of birds was titrated by using haemagglutination inhibition (HI) test and results recorded that both the NDV4HR (32.49 ± 23.94) and BCRDV (28.28 ± 10.54) produced more or less similar serological response at two weeks after booster vaccination. The results of challenged experiment showed that the NDV4HR vaccine ( 80% ) apparently conferred higher protection to birds than the BCRDV vaccine (70%). Therefore both the vaccines may be recommended to control ND in commercial chickens but NDV4HR vaccine could provide a practical method of control ND in rural scavenging chickens.

This study compared the immunogenicity of alum-precipitated formalin-killed fowl cholera vaccines (BAU-FCV and LRI-FCV) in Jinding ducks. The ducks were divided into three groups (A = 14, B = 14, C = 12). Group A was inoculated with BAU- FCV 0.5 mL and group B with LRI- FCV 1.0 mL intramuscularly (im) at the age of six weeks and group C served as unvaccinated control. Booster vaccination was administered similarly at 11 weeks of age in groups A and B. Challenge infection was given to all birds two weeks after booster vaccination. Passive Haemagglutination Assay (PHA) antibody titres in group A were 59.4 ± 4.6 21 days after primary vaccination, 137.1 ± 21.8 15 days after booster vaccination, 100.6 ± 12.9 21 days after booster vaccination, and 256.0 ± 48.4 15 days after challenge. In group B, titres were 50.3 ± 6.5, 118.9 ± 9.1, 91.4 ± 12.9, 237.7 ± 51.7, respectively, whereas titres in group C remained at ?4.0 ± 0.0. The antibody titres were insignificant when compared between pre-vaccination and 21 days after primary vaccination in both vaccinated groups (A and B). PHA antibody titres of groups A were significantly (P < 0.0001) increased at 15 days after booster and in case of group B the antibody titres were insignificant. At 15 days after challenge the antibody titres were highly significant in both groups (A and B). There was no significant difference between the two vaccinated groups. Following challenge infection with virulent Pasteurella multocida 88.9% of birds vaccinated with BAU-FCV, and 77.8% of birds vaccinated with LRI-FCV survived, while all unvaccinated birds died. Both vaccines were safe and effective. DOI: http://dx.doi.org/10.3329/bvet.v30i2.18253 Bangl. vet. 2013. Vol. 30, No. 2, 41-45

The research work was performed to investigate the immunogenicity of Salmonella vaccine produced at LPVRPC, BAU Mymensingh. The vaccination was performed at the Phenix Hatchery Ltd. Gazipur in Hy-sex brown and HY-sex white chicken designated as group A and group B respectively. Group A and B were subdivided into A1, A2, A3, B1, B2 and B3 groups containing eight birds each. Group C was maintained as unvaccinated control. Birds were immunized following schedule of the LPVRPC. Each bird was vaccinated SC at six weeks of age followed by a subsequent booster dose after 45 days. After four weeks of primary vaccination the mean PHA antibody titres were 96.00±34.21 in group A1 and 96.00±34.21 in B1 group. Prebooster vaccination the mean PHA antibody titres were 88.00±33.12 in group A2 and 88.00±33.12 in B2 group. At four weeks of booster vaccination the mean PHA antibody titres were 104.00±33.12 in group A3 and 104.00±33.12 in B3 group. The mean ± PHA antibody titre in chickens of group C was ? 4.0±0.00. Salmonella vaccine prepared at (LPVRPC) Department of Microbiology and Hygiene, BAU induces satisfactory level of antibody in chickens determined by PHA test conducted in an on-farm study of layer chickens.DOI: http://dx.doi.org/10.3329/bjvm.v13i1.23705Bangl.

Persistence of maternally derived antibody to Baby Chick Ranikhet Disease Vaccine and its influence on vaccination programme in chicks of vaccinated and nonvaccinated origin were determined during the period from July 2005 to May 2006. The study suggested an effective vaccination schedule of Baby Chick Ranikhet Disease Vaccine in chicks of vaccinated and nonvaccinated origin. The optimum age for vaccination of chicks of vaccinated and nonvaccinated origin were determined by inoculating vaccine following two different vaccination schedules. In one schedule chicks of group C of vaccinated origin and group F of nonvaccinated origin were vaccinated primarily at day 4 and was boosted at day 19 and in another schedule the chicks of group D of vaccinated origin were vaccinated once at day 14 without giving booster dose. It was found that maternally derived antibody passed over from the parents to progeny chicks and remain protective for the chicks of group A of vaccinated origin until 18 days of age and the chicks of group B of nonvaccinated origin until 5 days of age. This maternally derived antibody was retained particularly up to 24 days and 11 days in chicks of group A and B obtained from parent vaccinated and nonvaccinated flock respectively. Chicks of group C primarily vaccinated with Baby Chick Ranikhet Disease Vaccine revealed slightly positive effect to rise of antibody during their gradual increase of age due to the presence of high level of antibody at the time of primary vaccination where as in chicks of group F antibody level was increasing impetuously due to the low level of antibody at the time of vaccination. Chicks of group D vaccinated at the state of subsidence of maternally derived antibody with Baby Chick Ranikhet Disease Vaccine showed impetuous production of antibody titers. Chicks possessing high level of maternally derived antibody may be vaccinated singly against Newcastle disease when they are 14 to 18 days old and chicks possessing low level of maternally derived antibody may be vaccinated twice at 4 and 19 days of age.

Hemograms and acute-phase proteins in adult male New Zealand White rabbits that had been experimentally infected orally with sporulated oocysts of Eimeria stiedai were evaluated over a 28-day period. Fifty animals were used, divided into two groups: group A infected with 1 × 10(4) sporulated oocysts of E. stiedai and group B inoculated with distilled water. On the seventh day after infection, the infected animals presented anemia and leukocytosis with neutrophilia and monocytosis. Protein fractionation by means of electrophoresis identified 19 acute-phase proteins with molecular weights ranging from 24 to 238 kD. Ceruloplasmin, transferrin and haptoglobin showed high levels on the seventh day after infection, with gradual increases in their concentrations until the end of the experimental period. Thus, from the data of the present study, E. stiedai is considered to be a pyogenic etiological agent for which the infection level can be monitored through the leukocyte count and serum concentrations of ceruloplasmin, transferrin and haptoglobin, and these can be recommended as complementary tests.

Two trials were conducted to test the value of sodium fluoride as an ascaricide for growing pigs kept on infested grounds. The ability of the drug to kep animals free from ascarides and the possible toxicity upon repeated treatment were also studied. Three groups of animals similar as to breeding, weight and age were used in Trial I. Group "A" served as control. Group "B" received 0.2 gm. of phenothiazine per pound or bodily weight and group "C" one per cent sodium fluoride mixed with ground feed. Except for slight variations in the procedure and the elimination of the phenothiazine treatment, Trial II was conducted in the same manner. The effectiveness of the different treatments given during the experimental period was measured by statistical analyses of the number of ascarid and non-ascarid eggs per gram of fresh rectal feces secured once every week, by the weight gains made by each animal, and by the number of Ascaris worms found upon visceral examination. The results obtained suggest that sodium fluoride at the rate of one per cent mixed in the feed every three weeks is a very satisfactory drug for killing Ascaris lumbricoides suis found in growing pigs raised on the ground. When fed repeatedly to growing pigs for periods of from 3 to 4 months it was effective in keeping the animals clean, with no toxic effects whatsoever. Phenothiazine at the rate of 0.2 gm. per pound of bodily weight administered every three weeks was found to be unreliable as an ascaricide. The data obtained during the two trials made suggest that sodium fluoride is specific against Ascaris lumbricoides suis.

Augmentation rhinoplasty is one of the most common plastic surgery procedures performed in Asia. Most Asian patients desire not only a natural-looking nose but also a nose with natural feel. Achieving such rhinoplasty outcomes with grafts has been a challenge for surgeons due to rigidity of grafting material. We propose a novel technique to address this limitation. A total of 200 healthy adult patients aged from 18 to 25 years were randomly chosen and classified into 5 groups: A, B, C, D, and control. Each group included 40 patients. The patients assigned to conventional grafting underwent rhinoplasty with L-shaped silicone prosthesis (group A) or expanded polytetrafluoroethylene (e-PTFE; group B), using traditional carving methods. The patients assigned to dynamic rhinoplasty underwent silicone (group C) or e-PTFE grafts (group D) using the modified double “V” method, which involves removing bilateral wedges from the graft to decrease rigidity. Patients in control group do not undergo the surgery. A 3-dimensional raster surface scanner was used to capture the images of the patients accurately and nasal mobility was measured. Subjective evaluations were carried out by a series of questionnaires asked to the patients. The angle α of nasal mobility was significantly lower in conventional grafting (23.09 [5.34] mm for silicone and 17.88 [4.96] mm for e-PTFE) versus the “V” carving (30.53 [3.76] mm for silicone and 23.77 [4.53] mm for e-PTFE; P < .05). The double “V” carving method is a simple, effective, and practical method for improving dynamic nasal outcomes in patient undergoing augmentation rhinoplasty.

SUMMARYIn the first experiment two groups of 11 Scottish Blackface ewes were given either 6·10 kg dried grass pellets plus 1·63 kg chopped dried grass daily (Group A) or 8·17 kg hay plus 1·32 kg oat pellets (Group B). During a 10-day experimental period individual dry-matter intakes ranged from 484 to 939 g/day (CV 22·3%) in Group A and from 613 to 883 g/day (CV 13·3%) in Group B. In Group B dry-matter intakes from oats were much more variable (10 to 149 g/day; CV 35·8%) than those from hay (530 to 762 g/day; CV 12·9%). Plasma protein-bound iodine (PBI) concentrations were significantly higher in the Group A sheep.In the second experiment the treatments were: group-penned, group-fed (GG); group-penned, individually fed (GI); and individually penned, individually fed (II). Within each treatment there were two groups of 12 ewes; one group was given a high level of feeding (H) and the other a low level (L) for a 7-week experimental period. Allowances of pelleted concentrates ranged from 7 to 15 g/kg in the L groups and from 18 to 26 g/kg in the H groups. The same mean quantities per kg were given to GG sheep, and food intakes ranged from 5·7 to 17·7 g/kg (CV 25·3%) in GGL and from 12·5 to 30·8 g/kg (CV 24·8%) in GGH. Plasma PBI concentrations were significantly higher in L sheep than in H sheep, and higher in GG than in II. Plasma non-esterified fatty acid concentrations were significantly higher in L sheep than in H sheep and higher in GG than in GI and II.The principal factors determining variations in food intakes between individual animals fed in groups and some of the nutritional implications of group-feeding sheep are discussed.

Reactive Oxygen Species (ROS) parameters and antioxidant enzyme activities in heart of Clarias gariepinus weighing (15 ± 1.7 g) in toxic exposure to mercury concentrations, 0.1 mg/ L group B, group C 10 mg/L ammonium chloride and group D 0.1 mg/L mercury and 10 mg/L ammonium chloride for 7 consecutive days at 26 ± 1°C temperature. Group A was exposed to water alone and serve as control. At the end of the experimental period, Reduced glutathione (GSH), NO levels and the activities of Peroxidase, Superoxide dismutase (SOD) and Alanine Amino Transferase (ALT) in heart were assayed. The result showed a significant increase (P <0.05) in the activities of ALT, Peroxidase, and SOD. However, a significant decrease in the levels of total protein content, GSH and NO were also observed. The results showed that the combined effect of mercury and ammonium had an adverse effect greater than that obtained individually.

In a prospective randomized controlled study, the possibility that children could regulate their own salivary immunoglobulins was investigated using cyberphysiologic techniques. Fifty-seven children were randomly assigned to one of three groups. Group A subjects learned self-hypnosis with permission to increase immune substances in saliva as they chose; group B subjects learned self-hypnosis with specific suggestions for control of saliva immunoglobulins; group C subjects were given no instructions but received equal attention time. At the first visit, saliva samples (baseline) were collected, and each child looked at a videotape concerning the immune system and was tested with the Stanford Children's Hypnotic Susceptibility Scale. At the second visit, an initial saliva sample was collected prior to 30 minutes of self-hypnosis practice or conversation. At the conclusion of the experiment, a third saliva sample was obtained. Salivary IgA and IgG levels for all groups were stable from the first to the second sampling. Children in group B demonstrated a significant increase in IgA (P &lt; .01) during the experimental period. There were no significant changes in IgG. Stanford Children's Hypnotic Susceptibility Scale scores were stable across groups and did not relate to immunoglobulin changes.

An experiment was conducted at the Khanpura Poultry Farm, near to the Babugonj campus of Patuakhali Science and Technology University, Patuakhali during the period from August to September, 2011 to evaluate the effect of growth promoter and multivitamin-mineral premix on the body weight gain in broiler chickens. A total of 90 ‘Cobb 500’ day-old broiler chickens were randomly divided into three equal groups (n = 30), namely Groups A, B and C. Broiler birds in groups A and B were supplemented with growth promoter and multivitamin-mineral premix, respectively in addition to commercial feed from day 4 till day 25. The dose of both the growth promoter and multivitamin-mineral premix was 2.5 g/kg of feed. Chickens of group C served as control and supplemented with commercial feed only. Body weight was recorded at three times as on day 11, 18 and 25, respectively. The mean body weight was insignificantly (p > 0.05) higher in birds of groups A (992.5±139.6g) and B (978.3±147.0g) than those of group C (926.7±133.2g). The percent increase in body weight gain compare to control was increased in both the supplemented groups (5.8% in group A and 8.8% in group B) though there was no significant difference. Based on the results, it is suggested that supplementation of growth promoter and multivitamin-mineral premix in broilers even after feeding of commercial feed has positive effect on the growth of broilers.DOI: http://dx.doi.org/10.3329/jbau.v10i2.14914 J.
