Coccidiosis is a disease of great economic importance for the emerging poultry industry of Bangladesh. Sulfonamides have been used extensively for treatment and control of chicken coccidiosis. However, there have been complaints regarding failure of Esb3 ® (sodium sulfachloropyrazine monohydrate; Ciba-Geigy) in treating clinical coccidiosis. Therefore this study was undertaken to examine the degree of sulfonamide resistance of field coccidian isolates. Four groups of 12-day-old chicks were infected with 104 sporulated oocysts of four field coccidian isolates. Each group contains four subgroups containing 8 chicks in each subgroup, among which one subgroup remained as infected untreated control and another 3 subgroups were treated with 30% Esb3 ® @ 1 , 2, or 2.5 g/l of drinking water for 3 consecutive days. The sulfonamide resistance was assessed on the basis of faecal oocyst counts and clinico-pathological findings. There was no significant difference (p >0.05) in weight gain between untreated chicks and the chicks treated @ 1 and 2 g/l. However, a significantly higher (p <0.05) weight gains were noted in subgroups treated with Esb3 ® @ 2.5 g/l. Chicks received treated with 2 g/l Esb3 ® received similar clinical coccidiosis and histopathological changes but little less oocyst counts as found in untreated infected control chicks. Chicks treated with 2 g/l Esb3 ® did not reveal clinical coccidiosis and revealed no or very minimal oocyst counts during the treatment period. But on histopathology, arrested or stunted parasitic stages were found during the treatment period whereas flourish parasitic development with subacute-chronic ulcerative caecitis was evident following withdrawal of treatment. These findings suggest that the drug only cause an arrested parasitic development rather than killing the parasite. Therefore, an alternative to the sulfonamides needs to find out for treating and controlling chicken coccidiosis.

Abstract This study was conducted to evaluate effects of chilled drinking water and cooled floor pads on behavior of lactating sows under heat stress. Sows were housed in individual farrowing stalls in two rooms with temperatures being controlled at 29.4°C (0700h to 1900h) and 23.9°C (1900h to 0700h). Sows in one room (treatment), but not in the other room (control) were provided with chilled drinking water (13 to 15°C) and cooled floor pads (15 to 18°C). Behavior of sows (n=15 sows/treatment; parity=1 to 6) was video recorded during farrowing, and d 1, 3, 7, 14, and 21 after farrowing. Videos were viewed to register birth time of each piglet. Number of drinking bouts and duration of each bout were registered for 2 h (1530h to 1730h) each day after farrowing. Postures (lying laterally, lying ventrally, sitting, and standing) were recorded by scanning video-recordings at 5-min intervals for 24 h each day after farrowing, and time budget for each posture was calculated. Data were analyzed using the Glimmix Procedure of SAS. No effect of treatment was detected for litter size born, farrowing duration, or birth interval (P &gt;0.33; Table 1). Neither frequency nor duration of drinking bouts was affected by treatment (P &gt;0.27). No significant difference was observed in time budget for each posture (P &gt;0.46) between treatment and control groups. As lactation progressed, sows increased drinking frequency (from 1.2 drinks/2h on d 1 to 4.9 drinks/2h on d 21; P&lt; 0.001) and time spent lying ventrally (8% to 14%; P&lt; 0.0001), standing (4% to 10%; P&lt; 0.001), and sitting (2% to 4%; P&lt; 0.0001), and decreased time spent lying laterally (86% to 67%; P&lt; 0.0001) in both control and treatment rooms. These results indicate that chilled drinking water and cooled floor pads did not affect behavior of sows during farrowing and lactation in the current study.

The topic is approached from the viewpoint of community air-pollution programs and control. After a brief discussion of the economic costs of atmospheric pollution in an industrial area, a skeleton outline of the important factors in weathering by pollutants is presented. A few of the factors are considered in detail under the general headings of soiling, erosion, and corrosion. Significant differences in weathering are found for industrial, rural, marine, and very dry climates. Most community surveys include routine tests of the dirtiness of the air but exclude corrosion tests, although this factor is of great economic importance. Methods of corrosion testing are considered, and it is concluded that they are not feasible yet for community surveys. Increasing interest in corrosion, however, is undoubtedly leading to a broader understanding of the problem.

Recharge Structures

A field study evaluated the performance of direct well recharge structures (DWRS) in order to harvest and filter farm runoff and its discharge into open dug wells to augment groundwater recharge. This was undertaken between 2016 and 2018 using a total of 11 wells in the Dharta watershed, situated in a semi-arid hardrock region of Udaipur district, Rajasthan, India. The depth to water level in each DWRS well was monitored weekly for 1 to 3 years before and after the DWRS was established, and water samples were taken for water quality analysis (pH, electrical conductivity (EC), total dissolved solids (TDS), turbidity, fluoride, and Escherichia coli) before and during the monsoon period. For each DWRS well, two control wells in close proximity were also monitored and sampled. Five of the DWRS established in 2018 also had flow meters installed in order to measure discharge from the filter to the well. The volume of water recharged through DWRS into individual wells during the 2018 monsoon ranged from 2 to 176 m3 per well. Although the mean rise in water levels over the monsoon was higher in DWRS wells than in nearby control wells, the difference was not significant. Values of pH, EC, TDS, and F decreased in DWRS and control wells as each monsoon progressed, whereas the turbidity of wells with DWRS increased slightly. There was no significant difference between DWRS and control wells for pH, EC/TDS, turbidity, or fluoride. The presence of E. coli in DWRS wells was higher than in control wells, however, E. coli exceeded drinking water guidelines in all sampled wells. On the basis of this study, it is recommended that rural runoff should not be admitted to wells that are used for, or close to, wells used for drinking water supplies, even though salinity and fluoride concentrations may be reduced. For this study, none of the 11 DWRS wells produced sufficient additional recharge to potentially increase dry season irrigation supplies to justify expenditure on DWRS. This even applies to the DWRS well adjacent to a small ephemeral stream that had a significantly larger catchment area than those drawing on farmers’ fields alone. An important and unexpected finding of this study was that no sampled open dug well met drinking water standards. This has led to a shift in local priorities to implement well-head water quality protection measures for wells used for drinking water supplies. It is recommended that parapet walls be built around the perimeter of such dug wells, as well as having covers be installed.

Research about the performance of local rabbit fed different level of concentrate based on   Daucus carota L.was conducted for 12 weeks at Dajan Peken Village, Tabanan District, Tabanan Regency. The research design used was Randomized Block Design with 5 replicates. The animals were allocated randomly into 4 treatments i.e. control ration carrot leaf (Daucus  carota L.) (R0), control ration with 10 g concentrate/head/day (R1), control ration with 20 g  concentrate/head/day (R2) and control ration with 30 g concentrate/head/day (R3).  Daucus carota L. and drinking water offered ad libitum. Results of the research showed that performance of the animals fed control ration with 30 g concentrate/head/day (R3) was higher  (P < 0.05) than that R0 (control) and other treatments. Carcass weight, meat, and fat of the animals fed ration R0 was lower (P < 0.05) compare to treatment R1, R2, and R3. There was no significant difference (P >0.05) to variables of carcass weight, bone weight, and meat bone ratio among R0, R1, R2, and R3 percentages. It could be concluded that the animals fed Daucus carota L. as basic ration that was supplemented with concentrate 30 g/head/day produced higher performance and carcass compare to the animals supplemented 20 g/head/day and 10 g/head/day.

Introduction: PIH is a common condition associated with changes in placenta. It leads to increased perinatal mortality. The present study was conducted to assess the morphological and histopathological changes in placenta in cases of pregnancy induced hypertension. Subjects and Methods: The present comparative study included 49 cases of PIH and 49 normotensive mothers. Clinical details and placental morphology were noted. Results: That the two groups are similar with no significant difference. Placental weight and diameter were similar in PIH and control groups (p>0.05). However, placental thickness and number of cotyledons were greater in PIH group (p=0.00) while placental volume was lower with significant difference (p=0.01). PIH group showed greater proportion of infarction, calcification, hyalinised area per 10 lpf and intervillous haemorrhage (p=0.00). Conclusion: PIH leads to gross and microscopic changes in placental morphology.

Pancreas will respond differently to stress situations, which results in histopathological changes in the gland. Glucagon and insulin are both secreted by pancreas, the former by alpha cells and latter by beta cells. Insulin may decrease during stress. These endocrine secretions enter the portal vein so that liver is exposed to high concentration of these hormones. This along with increase in its antagonistic hormones can contribute to the stressed induced hyperglycaemia. The aim is to find and compare the weight and histopathological changes of Pancreas in suicide and non suicide deaths. The pancreas were dissected during the autopsy from the cases with known history of death due to alleged suicide with clear history of non administration of steroids and was declared brought dead at GMCH, Chandigarh. The removed glands were preserved and fixed with 10% formalin for more than 2 weeks. After the period of fixation, grossing and section of gland was done, and slides of each subject was prepared and studied.In suicide group maximum weight is 78.2 grams and minimum is 67.3 grams. In non suicide maximum weight is 78.2 grams and minimum is 65.5 grams. The mean weight of the pancreas in the suicidal group was 71.27 grams and the standard deviation was 2.18 grams, whereas the mean weight of the pancreas in the non- suicidal group was 70.87 grams and the standard deviation was 2.63 grams. The P value comes out to be 0.41. Of the total 100 cases, only three (3%) revealed significant pathological findings and the rest 97 (97%) were histologically normal. In the study group there was one case each of pancreatic abscess, and necrotising pancreatitis. Pancreatitis abscess was diagnosed when the histology revealed focus of necrosis of the pancreatic parenchyma with dense neutrophilic infiltration. Necrotising pancreatitis showed extensive necrotising inflammation of the pancreatic parenchyma. In the control group there was only 1 case (2%), of chronic pancreatitis. Chronic pancreatitis was labelled when fibrosis of the pancreatic parenchyma with mild lymphomononuclear cell infiltration. There was no significant difference between the weight of the pancreas in the suicidal and the non-suicidal group. Pathological findings were twice as common in the suicidal group as compared to the non-suicidal group.

Introduction: Ocimum basilicum (OB), a herb known for its antihypertensive, anticholinesterase and antioxidant properties was investigated for possible intraocular pressure (IOP) lowering effects in rabbits with ocular hypertension (OHT). Methods: The IOP lowering effect of a single drop of OB extract (OBE) was evaluated in oculonormotensive rabbits using three concentrations (0.25, 0.5 and 1% w/v). The concentration showing maximum IOP reduction was further evaluated in rabbits with water-loading and steroid-induced OHT. Results: IOP lowering effect of OBE 0.5% in oculonormotensive rabbit eyes was significantly greater compared to OBE 0.25% (p<0.05) but was comparable (p>0.05) to OBE 1%. Therefore, 0.5% concentration was selected for further evaluation. Pretreatment with OBE (0.5%) caused significantly lower increase in IOP after water loading amounting to 23.39% above baseline as compared to 54.00% in control eye, 15 minutes post water loading. At 60 minutes, post water loading, mean IOP rise was 95.12% and 63.58% in control and test eyes, respectively. Significant difference between the mean IOP of two eyes persisted during the 2nd hr. In rabbits with steroid induced OHT, OBE 0.5% produced a mean IOP reduction of 24.73% at the end of first hr and the mean peak IOP reduction of 31.63% was observed at the end of 2 hr. A significant difference between the IOP of test and control eyes persisted from 1 to 6 hr. Conclusions: Ocimum basilicum seed extract showed significant IOP lowering effect in rabbits with water loading and steroid induced OHT, however, its utility as an effective antiglaucoma medication needs further investigations.

Introduction: The role of virgin coconut oil in the treatment of allergic rhinitis is controversial. Thus, the aim of the present study is to determine the effects of virgin coconut oil ingestion, in addition to standard medications, on allergic rhinitis. We also studied the side effects of consumption of virgin coconut oil. Methods: Fifty two subjects were equally divided into test and control groups. All subjects received a daily dose of 10mg of loratadine for 28 days. The test group was given 10ml of virgin coconut oil three times a day in addition to loratadine. The symptoms of allergic rhinitis were scored at the beginning and end of the study. Results:, the symptom score were divided into nasal and non-nasal symptom scores. Sneezing score showed a significant difference, however the score was more in control group than test group, indicating that improvement in symptom was more in control group. The rest of the nasal symptom and non-nasal symptom score showed no significant difference between test and control groups. Approximately 58% of the test subjects developed side effects from consumption of virgin coconut oil, mainly gastrointestinal side effects. Conclusion: In the present study, ingestion of virgin coconut oil does not improve the overall and individual symptoms of allergic rhinitis, furthermore it has side effects.

AbstractThe present study investigated possible effects of dietary malic acid on the expression of immunity, antioxidant and growth related genes expression as well as skin mucus immune parameters in common carp. Common carp (Cyprinus carpio) fingerlings were fed diets supplemented with different levels (0 [control], 0.5%, 1%, 2%) of malic acid (MA) for 60 days. The results revealed highest expression levels of immune-related genes (tnf-alpha, il1b, il8 and lyz) in skin of common carp fed 2% MA (P < 0.05). Regarding 1% MA treatment comparison with control group, significant difference was noticed just in case of lyz (P < 0.05). Evaluation of growth related genes expression revealed no significant difference between treatments (P > 0.05). The study of antioxidant related genes (gsta and gpx) in common carp skin fed with MA, showed significant difference between treated groups and control (P < 0.05). Carps fed with 2% MA had highest alkaline phosphatase activity in skin mucus compared other treated groups and control (P < 0.05). There were no significant difference between 0.5% and 1% and control (P > 0.05). The study of total protein and total immunoglobulin (Ig) in common carp skin musus revealed no alteration following MA treatment (P > 0.05). The present data demonstrated that feeding with MA altered immune and antioxidant genes expression in skin mucus of common carp.
