Authors: Haque Fowzia , Hassan AKM Sayeed , Jahan Miskat Ara Akhter , Roy Shyamal K 
Published: July 2012

A protocol was established for in vitro shoot proliferation and plant regeneration of a rare medicinal shrub of Bangladesh, Plumbago indica L. (Plumbaginaceae) using shoot tip and nodal explants. Best shoot induction was observed on MS medium supplemented with 0.5 mg/l BAP, in which 92% of nodal explants responded to produce maximum number (42.8 ± 1.18) of shoots per explants. In vitro raised shoots rooted on half strength of MS medium with 0.5 mg/l IAA. For acclimatization and transplantation, the plantlets in the rooting culture tubes were kept in normal room temperature for 7 days before transplanting them in pots containing soil where plantlets were reared for three weeks. The survival rate of regenerated plantlets was 82%. DOI: http://dx.doi.org/10.3329/bjsir.v47i2.11452 Bangladesh J. Sci. Ind. Res. 47(2), 197-202, 2012

Published: July 2012

An efficient protocol was developed for plant regeneration, multiplication and rooting under in vitro condition in pointed gourd. Highest percent of shoot regeneration was 91.66%, when nodal explants were cultured on MS+1.0 mg/1 BAP. The maximum number of shoots (4.8) per explant was observed in MS + 1.0 mg/1 BAP + 0.2 mg/1 NAA from nodal segment. Among the two explants, nodal segment was found better for shoot regeneration and multiplication. The best response towards root induction was achieved on half MS medium supplemented with 0.4 mg/1 NAA. The regenerated healthy rooted plantlets were transferred to small plastic pot containing garden soil and compost in a ratio of 2:1. Immediately after transplantation the plantlets were covered with polythene bag to prevent desiccation. After acclimatization the plantlets were successfully transferred to the garden soil and the percentage of survivability in such condition was 90%.

Effects of antimony and tungsten additions in Mn_Mo_Sn oxide electrocatalyst for hydrogen production from electrolysis of 0.5 M NaCl solution
Authors: Bhattarai Jagadeesh 
Published: July 2012

Successfully tailored new types of nanocrystalline Mn-Mo-Sn-W-O and Mn-Mo-Sn-W-Sb-O electrocatalysts on the intermediate layer of Ir1-x-ySnxSbyO2+0.5y on titanium metal substrate for the production of hydrogen gas from electrolysis of 0.5 M NaCl solution of pH 1 at very high current density of 1000 A.m-2 with forming less than 0.3 % of the environmentally harmful chlorine. Antimony and tungsten additions are more effective for better durability of both the electrodeposited Mn-Mo-Sn-X(X=Sb,W)-O/Ir1-x-ySnxSbyO2+0.5y/Ti anodes than that of Mn-Mo-Sn-O/Ir1-x-ySnxSbyO2+0.5y/Ti anode for long period electrolysis of acidic 0.5 M NaCl solution to produce hydrogen. The high oxygen evolution efficiency (OEE) of the quadrate or more oxides electrocatalysts (i. e., 99.7-99.9 % OEE) maintained during prolonged electrolysis and even after electrolysis for five or more months. The Mn-Mo-Sn-X(X=Sb,W)-O/Ir1-x-ySnxSbyO2+0.5y/Ti anodes showed about 99.7-99.9 % of oxygen evolution efficiency. DOI: http://dx.doi.org/10.3329/bjsir.v47i2.11459 Bangladesh J. Sci. Ind.

Loss of vitamin A in fortified edible oils and ghee during cooking in asian traditional style
Authors: Akhtar Hifza , Tahir Lubna , Mahmud Shahid , Hamid Shahnaz 
Published: July 2012

Vitamin 'A' is essential for normal growth and its deficiency causes night blindness, affects the regulatory function of skin and reduces the general resistance of organism to infection. This deficiency does not occur by using balanced diet or by fortification of staple food with appropriate amount of Vitamin 'A'. In Pakistan vitamin 'A' fortification is done in vegetable ghee/cooking oil. It is generally assumed that fortified amount of vitamin 'A' is fully destroyed when the food is cooked at high temperature. The present study was focused to examine the effect of Pakistani traditional cooking style on the degree of destruction of vitamin 'A' mandatory fortified in the vegetable ghee/ cooking oils. The study indicates that there are some losses of Vitamin A of the fortified oils during cooking. However in case of deep fat frying destruction of added vitamin 'A' is more pronounced. The loss of vitamin 'A' was less than 50%, when the food was cooked in Pakistani style in case of all the cooking oils/ vegetable ghee. In prolonged frying conditions substantial amount of vitamin 'A' (45%) remains in the oil. Any how, this retention of vitamin 'A' is sufficient to meet the body requirements when oils/ghee was fortified according to the prescribed Pakistan Pure Food Rules 1965 i.e. 33,000 IU per Kg.

Published: July 2012

Background: Iodine is essential for normal growth, mental development and survival of infants. Bangladesh is an iodine deficient region. Breast milk is the only source of iodine for exclusively breast-fed infants. Routine measurement of breast milk iodine concentration is very difficult in our country due to some social and religious barriers. So, we designed this study in our population using urinary iodine as the indicator for assessing iodine status. Objectives: To assess the iodine status of lactating mothers and their breast-fed infants and to propose a method on how to predict the iodine concentration in breast milk. Materials and Methods: This observational analytical study was carried out in the department of Biochemistry, Bangabandhu Sheikh Mujib Medical University, Dhaka with active cooperation of Kumudini Womens Medical College Hospital, Mirzapur, Tangail involving fifty lactating mothers and their exclusively breast-fed infants. Early morning urine and breast milk samples were collected in dry and clean plastic container free from any chemical contamination. All statistical analyses were done by using SPSS (Statistical Programme for Social Science) 12 version software package for windows. Results: The median (range) urinary iodine concentration of lactating mothers and their breast-fed infants were 225.25 ?g/L (61.50-530.00) and 225.75 ?g/L (100.50-526.50). 96% (48) mothers had no biochemical iodine deficiency (UIE ?100?g/L), only 4% (2) mothers had mild biochemical iodine deficiency (UIE 50-99?g/L). There was no biochemical deficiency of breast-fed infants. The median (range) breast-milk iodine concentration was 157 ?g/L (54.50-431.50) which was more than three times of recommended minimum concentration (50 ?g/L). Iodine in breast milk of lactating mothers positively correlated with their urinary iodine excretion (P<0.01). Infants urinary iodine positively correlated with iodine concentration in breast milk (P<0.01) and also positively correlated with urinary iodine excretion of lactating mothers. Conclusion: Lactating mothers and their breast-fed infants in this study were found iodine sufficient. Urinary iodine concentration of lactating mothers predicts the iodine content of their breast milk. DOI: http://dx.doi.org/10.3329/jemc.v1i1.11132J Enam Med Col 2011; 1(1): 15-18

Published: July 2012

Background: Establishment and maintenance of breastfeeding in preterm low birth weight (PT LBW) neonates after discharge from hospital is challenging and may be affected by multiple factors. We designed this study to find out the association of these factors with breastfeeding in our population. Objectives: To observe the rate of exclusive breasrfeeding (EBF) among the PT LBW neonates at one month follow up and to identify the factors that are related with the maintenance of EBF. Materials and Methods: This observational study was conducted during the period from July 2009 to October 2011 in Enam Medical College Hospital (EMCH). Preterm infants ? 34 wks gestation, stayed in the NICU for >3 days and discharged home were eligible. Mothers were interviewed at one month follow-up after discharge. Infants who were given only breast milk up to 4 weeks were termed as Exclusively breastfed (EBF) and who were given formula milk in addition were labeled as Nonexclusively breastfed (NEBF). Baseline information regarding maternal demography, delivery of the baby, feeding during discharge was taken from database of neonatal ward. Results: Among 89 infants, 37 (42%) were female and 52 (58%) were male, including 5 twins. Gestational age ranged from 29 to 34 weeks (mean 32±2), and birth weight ranged from 1100 to 2200 grams (mean 1763±20 g). At one month follow up visit 19% (17/89) were found to be NEBF and 81% were EBF. Factors significantly associated with EBF were shorter duration of hospital stay (p=0.001), method of feeding at discharge (p=0.001), mode of delivery (p=0.004), below average socio-economic status (p=0.03), maternal education (p=0.02), number of antenatal visits (p=0.02) and larger birth weight (p=0.038). Conclusion: A variety of factors may affect EBF in PT LBW babies. Extensive counseling of the mothers during antenatal visits, counseling of the family members regarding the advantages of exclusive breastfeeding is necessary. Support should be provided for the mothers both in the hospital and also outside the hospital for a long period. DOI: http://dx.doi.org/10.3329/jemc.v1i1.11135J Enam Med Col 2011; 1(1): 24-30

Published: July 2012

Background: The distribution pattern of ABO and Rh-D blood group in our country including the tribal people is not fully established as elaborated and large scale studies have not been carried out on it. Therefore this study was designed to observe the distribution pattern of ABO and Rh-D blood groups among the Garo tribes of Mymensingh and general people of Dhaka city. Objectives: To determine and to compare the distribution pattern of ABO and Rh-D blood groups among the Garo tribal people of Mymensingh and general people of Dhaka city and to compare this distribution between this two groups. Materials and Methods: This observational study was conducted in the Department of Physiology, Dhaka Medical College, Dhaka from July 2008 to June 2009. After proper ethical consideration total 900 Garo people of Mymensingh and 784 general people of Dhaka city were included in this study. The Garo localities and the general people of Dhaka city were selected by systematic random sampling. ABO and Rh-D blood groups were determined by the antigen antibody agglutination test of slide method. Chi square statistical analyses were done to compare the results of ABO blood group systems between the Garo people and general people of Dhaka city. Results: This study revealed that there are significant variations in the distribution of ABO and Rh-D blood groups between the Garo tribal people of Mymensingh and the general people of Dhaka city. In this study it was observed that blood group A was apparently predominant in Garo population, while blood group B was predominant in general population (p<0.001), blood group AB and O were almost similar in both groups. Rh typing of the participants reveals that majorities of both groups were Rh positive. Rh negative persons are rare in both populations, but it is extremely rare in the Garo population (0.9%). Conclusion: From the findings of the present study it can be concluded that distribution of ABO and Rh-D blood groups varies between the Garo tribal people and the general people of Dhaka city.

Selection of Blood (Packed RBCs) for Transfusion in Newborn Baby up to the Age of 4 Months
Authors: Khan Ghulam Mostafa 
Published: July 2012

Proper selection of donors blood group is essential to prevent transfusion hazards. It is known that ABO antigen is fully developed at birth but the newborn baby does not produce ABO antibodies until 3 to 6 months of age. The ABO antibodies present in the serum of newborn babies are derived from mothers blood due to placental transfer. So the blood group of the newborn baby is done by ABO antigen grouping (forward grouping) only, antibody grouping (reverse grouping) is not required. In case of transfusion of blood in newborn under 4 months of age, cross-matching of donors blood is done with the mothers blood if it is available. We know, recipients same group of blood is always preferable in case of transfusion in adults or older children. But selection of blood for transfusion in the infants under 4 months of age depends on the mothers blood group as well. If the mothers blood group differs from the infants blood group, the infants same group of blood may not be selected for transfusion. For example, if the mothers blood group is O and the newborn blood group is A or B, infants same group A or B group blood could not be transfused, because the anti-A & anti-B antibodies can be derived in the infants serum from mothers blood which may react with the A or B antigen of the donors blood. In this case O group packed RBCs should be selected for transfusion. O group whole blood may contain IgG anti-A and anti-B antibodies in the plasma which can react with the A or B antigen of the infants blood. So to avoid anti-A & anti-B antibodies in O group, plasma should be discarded and the packed RBCs should be transfused. In case of Rh-negative mother with Rh positive baby, Rh antibody may develop in mothers blood and Rh antibody may enter into babys circulation, in this case the infant should be transfused with Rh-negative blood to avoid Rh antigen & antibody reaction. So for the selection of blood for transfusion in newborn baby up to the age of 4 months mothers blood group is important to select the appropriate blood.

Réinventer l'école, réinventer l'administration
Authors: Aebischer Sylvie 
Published: July 2012

Résumé Les prémices du discours managérial dans l’éducation sont bien antérieures à la LOLF et sont à rechercher en France dès les années 1980. La loi d’orientation pour l’éducation de 1989 dite loi Jospin est un moment clé de ce tournant politique, alors même qu’elle est généralement lue comme un texte essentiellement pédagogique. L’article éclaire le « moment réformateur » de 1989 à partir d’une scène trop peu étudiée en science politique : le travail d’élaboration de la loi au sein du cabinet ministériel. La prégnance de ce prisme managérial dans ce texte pédagogique s’explique d’abord par l’étude de ses producteurs et de leurs modes de travail. En réintégrant l’analyse des trajectoires des conseillers techniques à la sociologie de l’action publique, cet article montre le lien entre leur origine sociale, leur socialisation professionnelle, leur rapport au système éducatif et leur attachement à la « Réforme de l’État ».
Le Conseil national des programmes (1985-1994) : l'institutionnalisation chaotique d'une entreprise réformatrice
Authors: Clément Pierre 
Published: July 2012

Résumé À la fin des années 1980, alors que la capacité mobilisatrice de la laïcité s’épuise et que la « démocratisation » semble dans l’impasse, le ministre de l’Éducation nationale, Lionel Jospin, initie un processus de rénovation des contenus d’enseignement. Créé en 1990, le Conseil national des programmes (CNP) a vocation à constituer la cheville ouvrière de cette entreprise réformatrice. À partir d’une enquête sur archives et par entretiens, cet article analyse les luttes de territoire bureaucratique entre les trois institutions – le CNP, l’Inspection générale et la direction des lycées et collèges – alors en conflit pour le monopole du pouvoir pédagogique. Il montre comment la codification progressive d’un nouveau modus vivendi institutionnel permet l’amorce d’une réforme en profondeur des programmes du second degré, dont le socle commun de connaissances et de compétences constitue l’aboutissement.
La création et la diffusion du « bac théâtre » : une offre scolaire promue « d'en bas »
Authors: Lemêtre Claire 
Published: July 2012

Résumé En se centrant sur un des aspects méconnus de la réforme des filières du baccalauréat au moment de la seconde explosion scolaire, l’article met en évidence le rôle déterminant des enseignants dans la mise en œuvre des politiques éducatives et de l’offre de formation en particulier. À partir de l’exemple du « baccalauréat théâtre » et à l’appui d’une enquête ethnographique menée dans la région des Pays de la Loire, le texte montre que cette nouvelle offre scolaire n’est pas seulement promue « d’en haut » dans la mesure où son émergence doit au moins autant à la mobilisation d’enseignants singuliers inscrits dans les sphères militantes et culturelles. L’occasion est alors donnée de rappeler combien la réussite d’une action publique réside aussi dans ses usages et appropriations par les acteurs de terrain.

Published: July 2012

Résumé Cet article traite du succès du changement organisationnel. Nous introduisons ces travaux empiriques par une illustration du problème industriel : comment structurer le changement organisationnel pour assurer une appropriation correcte de l’état futur souhaité. À partir d’une analyse de la littérature, nous proposons une vision où le changement organisationnel est supporté par un double processus d’appropriation : appropriation au niveau de l’ensemble de l’organisation d’une part, et appropriation par les individus d’autre part. Nous montrerons ensuite que le projet est un moyen valide de gérer le changement organisationnel et de structurer le processus d’appropriation global par l’entreprise. Dans l’optique de soutenir le processus d’appropriation de la nouveauté par les individus, nous avons développé une méthode d’accompagnement intégrée à la gestion du changement par projet. Nous proposons un phasage générique des actions d’accompagnement par rapport aux phases d’un projet, et aux processus d’appropriation du changement par l’organisation et les individus. À partir d’une étude de trois ans des projets d’un acteur majeur du secteur aéronautique en France, nous présenterons enfin les apports de notre méthode au niveau de l’appropriation organisationnelle et individuelle.
