Effect of sub-lethal doses of thiamethoxam (a neonicotinoid) on hemato-biochemical parameters in broiler chicks

This project was designed to observe the hemato-biochemical effects of sub-lethal doses of thiamethoxam (TMX) in broiler chicks. A-day old chicks (n?=?90) were procured from the local market and maintained under standard housing conditions and divided into five equal groups (18 birds/group). The experimental trial continued for 45?days. Sub-lethal doses of TMX including 50, 100, 200 and 400?mg/kg B.W. to groups A, B, C and D were administered through crop tube, respectively. Group E served as a control. Blood and serum samples were collected from each group on 10th, 17th, 24th, 31st, 38th and 45th day of the experiment. The data were analyzed through ANOVA by MSTAT-C. All hematological parameters were determined. Serum samples were analyzed for ALT, AST, total proteins and urea. It was concluded from this study that even sub-lethal doses of TMX have toxic effects on hematology and biochemical parameters.     

Synthesis, anticonvulsant and neurotoxicity screening of some novel 1,2,4-trisubstituted-1H-imidazole derivatives

A series of 1,2,4-trisubstituted-1H- imidazole derivatives (4a-o) was synthesized by reacting 2,4-disubstituted-1H-imidazoles (3a-o) with chlorobenzene in the presence of triethylamine. Phenylglyoxal (2) was reacted with different aromatic aldehydes in the presence of ammonium acetate and glacial acetic acid to afford the disubstituted imidazoles (3a-o). The structures of the synthesized compounds were confirmed on the basis of their elemental analysis and spectral data results. Anticonvulsant activity was shown by majority of the synthesized compounds in the maximal electroshock (MES) and subcutaneous pentylenetetrazole (scPTZ) screens when given i.p. to mice. In anticonvulsant screening, only one compound 4k showed potent activity comparable to that of standard drugs phenytoin and carbamazepine. Compounds 4a, 4c, 4e, 41 and 4n passed the rotorod test successfully without any sign of neurological deficit.     

Introduction of the injectable contraceptive NET-EN into family planning clinics in Bangladesh

In preparation for introducing the injectable contraceptive norethisterone enanthate (NET-EN) into the national family planning program, a field study was conducted in 6 family planning clinics in Bangladesh. 3 of the clinics were located in Dhaka, the capital city, 1 was located in a town approximately 15 kilometers from Dhaka, and the other 2 clinics were located several hundred kilometers from Dhaka. A total of 913 women were chosen to receive injections of NET-EN every 8 weeks for 6 months and every 12 weeks thereafter. The mean age of the subjects was 26.8 years, and the mean number of live births was 3.4. The overall cumulative discontinuation rates were 26.3/100 women at 6 months, 37.3/100 at 12 months, and 42.9/100 at 18 months. The most common reason for discontinuing was a disturbance in bleeding. Heavy and/or prolonged bleeding was the single most frequent reason (6.3/100 women at 12 months), but amenorrhea was not uncommon (5.1/100 women at 12 months), while irregular bleeding or spotting was given as a reason somewhat less frequently (3.9/100 women). 3 women became pregnant during the study, giving a cumulative pregnancy rate of 0.4/100 women at 18 months. A variety of complaints fell within the category of "other medical reasons," the most common being fatigue, headache, and dizziness. The overall discontinuation rates varied markedly by center, as did the reasons for discontinuation. The lowest discontinuation rate of 14.7/100 women at 12 months was seen in the Mohammedpur Fertility Services and Training Center. This rate was considerably lower than that in any other center. The highest discontinuation rate was found by the Bangladesh Association for Voluntary Sterilization -- 52.0/100 women at 12 months. The variation in rate of discontinuation because of bleeding disturbances was most dramatic, with relatively high rates at the Bangladesh Association for Voluntary Sterilization, markedly low rates in the Mohammedpur Fertility Services and Training Centre, and intermediate rates elsewhere. Neither the overall discontinuation rate, nor the individual reasons for discontinuation varied much by age group. The most notable finding regarding discontinuation of NET-EN was the marked difference between centers. This is particularly notable given the lack of any major differences with respect to age, parity, residence, and history of contraception of the subjects. These findings suggest that the specific approach used in each clinic had a considerable impact on continuation rates and acceptance of NET-EN.     

Development of an integrated care pathway for the management of hemiplegic shoulder pain

Purpose: To improve clinical management of patients with hemiplegic shoulder pain through development of an evidence-based multidisciplinary integrated care pathway (ICP), and to use this to audit quality of care against predefined standards. Methods: The ICP was developed by a team of medical, paramedical and nursing staff. The evidence base was established through a systematic literature review supplemented by clinical consensus to ensure best practice where scientific evidence was lacking. Following development, performance was assessed against standards in a cohort of stroke patients with hemiplegia (n=32) consecutively admitted to a regional unit providing in-patient rehabilitation for young patients with complex disabilities. Results: Performance showed improvements in assessment and documentation of pain and in initial care, including analgesia and application of positioning/handling protocols. However, review and response to continuing or changing symptoms were poorly documented. Changes to the ICP were introduced to improve this. Conclusions: Principal benefits have been to raise awareness of shoulder pain, to educate staff and prompt management in line with recommended best practice, but strong leadership is essential to ensure continuity in clinical practice. Future research is needed to establish whether improved quality of care offsets the substantial investment of staff time in ICP development.     

Domestic Violence During Pregnancy: Evaluating the Impact on Maternal and Perinatal Health—A Pilot Study in Uttar Pradesh

IntroductionDomestic Violence [DV] is a global health problem of pandemic proportions. WHO identifies it as psychological, physical or sexual violence or threats of the same, in the premises of one’s home. The perpetrator can be husband, intimate partner, friend or a family member. DV during pregnancy has widespread implications on adverse obstetric maternal and foetal outcomes.Aim of the StudyTo find out the prevalence of domestic violence in antenatal women and observe the association between DV and maternal and perinatal outcome.MethodologyIt is a cohort study carried out at ELMCH, over a period of 10 months. Data were collected from pregnant women reporting to the outpatient department of obstetrics and gynaecology in their third trimester of pregnancy. The pregnancies were followed up till delivery and one week postpartum to study the obstetric and perinatal outcome. Appropriate statistical methods were applied to determine significance of the observations, and odds ratio was calculated for the risk factors.ResultsThe prevalence of DV during pregnancy was 22.2%, with psychological violence being the most common form observed. Increased relative risk was found for hypertensive disorders of pregnancy, antepartum haemorrhage, recurrent urinary tract infection and preterm labour. Apgar scores of babies in affected mothers was lower, and there were significantly greater NICU admissions. This was independent of period of gestation at delivery.ConclusionDV affects at least 1/4th of antenatal women. Majority of them do not realise the extent and forms of DV and accept the violence as a routine norm of marital life. DV during pregnancy has a significant association with adverse obstetric and perinatal outcomes.     

Craniofacial morphology in orthodontically treated patients of Class III malocclusion with stable and unstable treatment outcomes

The purpose of this study was to investigate morphologic features of the craniofacial skeleton in treated adolescent patients with Class III malocclusion. Fifty-six subjects were divided into 2 groups, with and without acceptable treatment outcomes, which were referred to as the stable and the unstable groups. The mean age at the initial stage was 9 years 3 months in the stable group and 9 years 4 months in the unstable group. All subjects underwent chincup therapy, with a mean duration of 3 years 9 months. On the basis of lateral cephalograms taken at 4 different stages, the means of the z scores for 20 measurements were calculated and compared between the 2 groups by means of the Student t test. Discriminant analysis was also conducted to extract key determinants to discriminate between the 2 groups. The gonial angle was significantly larger in the unstable group than in the stable group at the initial stage, and this increased over time. The mandible of the unstable group exhibited downward-and-backward rotation during early treatment and then rotated in an upward-and-forward direction after the correction of the anterior crossbite. A significant forward growth of the mandible was also found in the unstable group for the same period. Furthermore, the gonial, N-A-Pog, and ramus plane to SN plane angles were selected as the significant variables for discriminating the 2 groups with a high precision. In conclusion, it is shown that upward-and-forward rotation of the mandible, in combination with the forward growth and displacement, is highly associated with unsatisfactory treatment outcomes after pubertal growth in growing Class III patients.     

Evaluation of hospitalized infants and young children with bronchiolitis - a multi centre study

Four hundred and twenty nine young children with bronchiolitis admitted consecutively in different hospitals of Bangladesh were evaluated. Three hundred and forty eight children studied for their putative risk factors, clinical profile, management and the outcome. Both cases and controls were examined for respiratory syncytial virus (RSV) antibody status. The diagnosis of bronchiolitis was made on the basis of first attack of wheeze in previously healthy children below two years of age. Detailed history including the possible risk factors, the management and daily follow-up on the ward and the outcome at discharge were documented through a structured questionnaire. Chest x-ray was done in each case to find out the radiological changes. Blood of 266 patients and 30 controls were studied for RSV IgM and IgG antibody by ELISA. There were 66% male and 34% female children. The median age of the children was 3.0 months and 82.7% were below 6 months of age. Most of the babies were born term (88%), with ABW (73%), by normal vaginal delivery (88%). Exclusive or predominant breast-feeding were given in 72% cases. The location of the patient was rural in 55% cases. Around half of the parents were illiterate or slightly educated (up to 5 years schooling) fathers 46.5% and mothers 56% and majority of the parents were poor (74%). In 52% cases the number of family members in one room were four or more. Half of the parents (52%) were smokes and there was atopy in 26.5% families. The clinical features of bronchiolitis were mostly cough (99%), respiratory distress (97%), feeding difficulty (93%) and fast breathing (96%) (median RR 68/min). Fever (1000F or more) was in only 33% cases, though parents complained in 90% cases. All children (100%) had wheeze and crackles in lungs in 96% cases. Liver could be palpable in 83% and spleen in 42% cases. Important radiological features were increased translucency (96%), increased interstitial markings (87%), hyperinflation (75%) and streaky densities (61%). In 69.6% cases TLC was 12,000 or less and only 15% with a neutrophil fraction greater than 60%. Children were positive for IgM antibody in 43.6% cases and both IgM and IgG in 5.3% cases. The main modalities of treatment were antibiotics (99%) (Ampicillin, 76%), oxygen therapy (83%), nebulised salbutamol (76%) and intravenous fluid (51%). The median duration of hospital stay was 4 days. Most of the children were discharged with improvement (96%) with 2% mortality. Not a single case was diagnosed as bronchiolitis in hospitals outside Dhaka. Cefrtiaxone (72.5%) and parenteral steroids (70.5%) were the mainstay of therapy there.     

Effect of anthelmintics on the enzyme activities of Setaria cervi (Nematoda: Filarioidea)

The present study deals with the comparative efficacy of Hetrazan, levamisole and tetramisole on the enzyme activities of adult Setaria cervi worms. The drugs were administered orally to white rats, intraperitoneally infected with the bovine filariid, Setaria cervi. Biochemical assays revealed the decreased activities of glucose-6-phosphatase, fructose-1,6-diphosphatase, lactate dehydrogenase and adenosine triphosphatase in the drug-treated worms. Hetrazan was relatively more effective than tetramisole and levamisole. A possible role of these enzymes in the energy supply and survival of the worm has been briefly discussed.     

Imipramine hydrochloride and desipramine hydrochloride as new reagents for detection of microamounts of blood in urine

Benzidine and o-tolidine, the hazardous carcinogens are still in use for the detection of blood in urine. Development of safer substitutes are of paramount importance. Unfortunately, the alternate available reagents lack specificity, sensitivity and reproducibility. Imipramine hydrochloride (IPH) and desipramine hydrochloride (DPH) are proposed as new reagents for the detection of blood in urine. Both the reagents impact to blood a green-blue to blue color, in the presence of acetic acid and hydrogen peroxide and the development of this color is explored under laboratory conditions. IPH or DPH compares favorably with benzidine and multistix methods. Both the reagents are relatively inexpensive, and have required sensitivity and stability. The proposed reagents offer advantages of relatively low sensitivity to endogenous vegetable peroxidases; hence, the test can be performed on samples taken from patients who are on a normal diet and the results are reproducible. Besides, the reagents, are non-carcinogenic and can replace benzidine and o-tolidine without any extra procedural difficulties as they also exhibit a similar blue color.     

The role of response in spatial attention: direct versus indirect stimulus-response mappings

Recent research has suggested that inhibition of return (IOR) develops more quickly when subjects must respond with an eye movement than when they make a manual response to the target (Perception and Psychophysics 62 (2000) 1512-1524). Four spatial cueing experiments were conducted where subjects had to indicate the location of visual targets. Within each of the oculomotor and manual modalities, responses could be either directed towards the target (saccade or pointing) or had a more complex stimulus-response (S-R) mapping. For both saccadic and manual responses, IOR onset was delayed as the required S-R mapping became more indirect. This finding further emphasizes the role of response-related processes in spatial attention. Possible explanations for this pattern of results are considered, including the notion that activity in prefrontal cortex, needed for execution of such abstract S-R mappings, may influence the time course of reflexive spatial cueing effects.
