Lifestyle pattern in selected slums in Mymensingh Municipal area.

Lifestyle is composed of cultural and behavioural patterns and lifelong personal habits that developed through processes of socialization. Lifestyle may be health promotive or detrimental to health. Health requires the promotion of healthy lifestyle. Many current day health problems are associated with lifestyle changes. Because of rising urban population, the number of slum dwellers is rising. The mobility of people from rural to urban areas is the main reason of the growing slum population in cities. This Descriptive, cross-sectional study was directed to assess lifestyle pattern in four purposively selected slums in Mymensingh Municipal area. Non-Probability purposive type of sampling technique was used for selecting the study unit. Sample size was one hundred and twenty-three (123) families. Data were collected by interview with one of the adult family members, preferably with the head of the family, with mixed type of interviewer administered questionnaire. There were 494 family members with an average family size of 4.02, while mean age was 24.58 years with a standard deviation (SD) of 17.79 years. Male-female ratio was 103:100. Of 409 members over 5 years, 174(42.54%) did not have schooling and were illiterate. At least 105(33.02%) members were house-wives, and 99(81.15%) members were smokers. An overwhelming majority (79, 64.23%) families had monthly income between 2000 to 4999 taka. As many as 55(44.72%) families lived in kaccha house, while 40(32.52%) had to live in "Jhupree". In cent per cent families, tube well was the source of water for drinking and other household purposes. A highest majority 121(98.37%) of the families had latrine, while the remaining 2(1.63%) did not have any latrine, and defecate in open air. Of 121 families, 78(64.46%) families had sanitary latrine, while 43(37.54%) did not have sanitary latrine. It was revealed that 86(69.92%) families had cell-phone, while 65(52.85%) families had television, 10(8.13%) families had radio, and 5(4.06%) families had DVD/VCR for recreational facilities. As many as 75(60.98%) respondents had correct knowledge, while the rest 48(39.02%) had incorrect knowledge on hand washing. Of 75, at least 66(88.00%) respondents practiced hand washing, while 9(12.00%) respondents did not practice it. As many as 110(89.43%) members sought medical help for major and minor illness of their family members, whereas the rest 13(10.57%) families did not. Of 110, 62(56.36%) families paid visit to government Hospital, while 22(20.00%) visited to private clinic, 12(10.90%) to pharmacy, 10(9.10%) to qualified doctors and 4(3.64%) to the traditional healers. As many as 58(52.71%) respondents mentioned that they preferred as the facilities cater service free of cost, while 32(29.10%) preferred for better and effective treatment, 16(14.55%) for close to their residence and 4(7.27%) for their belief. Living condition of slum dwellers is considerably low due to low income and inadequate education. Moreover, poor physical environment with unsanitary excreta disposal method is commonplace in slum areas. Existing lifestyle of slum dwellers is unacceptable, and should be improved so that they can contribute to the national development.

Specific flavonoids induced nod gene expression and pre-activated nod genes of Rhizobium leguminosarum increased pea (Pisum sativum L.) and lentil (Lens culinaris L.) nodulation in controlled growth chamber environments.

The gram-negative soil bacteria Rhizobium spp. infect and establish a nitrogen-fixing symbiosis with legume crops which involves the mutual exchange of diffusable signal molecules. In this study, Rhizobium leguminosarum containing a nod-lacZ gene fusion was used to screen the most effective plant-to-bacteria signal molecules for pea and lentil and the induction conditions. Out of a number of signal compounds including apigenin, daidzein, genistein, hesperetin, kaempferol, luteolin, naringenin, and rutin, hesperetin and naringenin were found to be the most effective plant-to-bacteria signal molecules. The induction of nod genes was temperature-dependent, where nod gene induction was decreased with dropping incubation temperature. The combination of hesperetin at 7 microM and naringenin at 3 microM resulted in better induction of nod gene activities compared to either hesperetin or naringenin alone. Nodulation and plant dry matter accumulation of pea and lentil plants receiving preinduced R. leguminosarum were higher than those of plants receiving uninduced R. leguminosarum cells in controlled environment growth chamber conditions. Preinduced Rhizobium with hesperetin at a concentration of 10 microM increased nodule number on average by 60.5% and dry matter accumulation by 14% in field pea at 17 degrees C, while it was 32% and 9% at 24 degrees C, respectively. Similarly, averaged over two rhizobial strains, a 59% and 6% increase in nodule number and biomass production at 17 degrees C, and a 39% and 27% at 24 degrees C, were obtained from lentil inoculated with hesperetin-induced R. leguminosarum, respectively.

Correlation of ultrasonographic findings with ultrasound guided fine needle aspiration of liver lesion.

Ultrasonographic findings of liver were correlated with cytological findings in a series of 50 patients. Multiple lesions described by ultrasonography and suggested as HCC/TB were proved to be metastatic in 60% cases and hepatocellular carcinoma in 40% cases by cytological examination. Multiple lesions suggested as metastatic lesions in ultrasonography was proved as such by cytology in 83% cases. Solitary lesion suggested as neoplastic in ultrasonography was proved as such in cytology in 90% cases. Of the 2 patients suggested as diffuse parenchymal lesion revealed cytological findings of cirrhosis in one case and that of TB in other. Serum alpha-feto protein and Carcinoembryogenic antigen (CEA) was done in all the cases. Serum alpha-feto protein was higher in hepatocellular carcinoma and CEA was higher in metastatic lesions. Ultrasound guided fine needle aspiration of liver can play more role in diagnosis and classification of liver disease than ultrasonographic comment alone, as it requires greater degree of precision to reach diagnostic accuracy.

Bradyrhizobium japonicum mutants with enhanced sensitivity to genistein resulting in altered nod gene regulation.

Bradyrhizobium japonicum mutants with altered nod gene induction characteristics were isolated by screening mutants for genistein-independent nod gene expression. Plasmid pZB32, carrying a nodY::lacZ transcriptional gene fusion, was introduced into B. japonicum cells that had been subjected to UV mutagenesis. Ten independent transformants producing a blue color on plates containing 5bromo-4chloro-3indolyl-beta-D-galactopyranoside but lacking genistein, indicative of constitutive expression of the nodY::lacZ reporter gene, were isolated. Beta-galactosidase activity assays revealed that while all of the 10 strains were sensitive to low concentrations of genistein, none exhibited truly constitutive nodY::lacZ expression in liquid culture. Soybean plants inoculated with three of the mutants were chlorotic and stunted, with shoot dry weights close to those of the uninoculated plants, indicating the absence of nitrogen fixation. Differences in the kinetics of nodY::lacZ expression and lipochitin oligosaccharide Nod signal production suggested that the strains carried different mutations. Some of these strains may be useful in mitigating the low root zone temperature-associated delay in soybean nodulation at the northern extent of soybean cultivation.

Unnatural deaths during Zakat distribution.

Zakat is an islamic religious directive to wealthy Muslims to distribute 2.5% of their total annual saving to the poor. Before Eid-ul-Fitr Zakat is distributed to share happiness and joy with the poor. Deaths due to stampede in uncontrolled crowds of poor during Zakat distribution made it a point of study. In this tragic accident during Zakat distribution on 26.4.91 at a Biri (cigarette) factory (10 k.m. away from the port city of Chittagong), the total number of deaths were 32, out of which 27 (84.37%) persons died of Traumatic Asphyxia and 5 (15.63%) from head injury and more than 100 were injured, mostly elderly female and children. The young and elderly male escaped.
