Status of knowledge and practice about complete tetanus toxoid immunization of unmarried female students of a public university in Dhaka.

Objective: The present study was undertaken to assess the level of knowledge and practice about tetanus toxoid immunization of a group students from a public university. Materials & Methods: This cross-sectional survey was carried out on 113 female students randomly selected from Dhaka University. The interview was conducted using a structured questionnaire. Results: Mean age of the respondents was 19.7±1.2 years (mean±SD). About 90% of the respondents knew about tetanus. Regarding age groups prone to develop tetanus, 49% respondents told ‘children <1 year’, 26.5% ‘neonate’, 14.7% ‘children of 1-5 years’, 3.9% ‘children of 6-12 years’, 5.8% ‘women of 15 years and above’. Respondents showed lack of knowledge about the target group for TT vaccination. None has mentioned about the necessity of TT immunization before the start of reproductive life. Regarding number of dose for complete vaccination 60% respondents mentioned ‘five’, 10.9% ‘three’ and 4.9% ‘two’. Twenty two percent (22.1%) of the respondents did not know. Over one-third (34.5%) of the respondents was found to be completely immunized, 24.8% on schedule, 17.7% incompletely immunized and 23% was not at all immunized. Respondents’ source of knowledge about TT immunization was TV in 35% cases followed by health workers 24%, newspaper 16%, radio and other sources 25%. Among the nonvaccinated group 50% respondents told of their unawareness about need for vaccination against tetanus before the start of their reproductive life, 15.4% told about lack of information regarding of place and time of vaccination and 19.6% complained about inconvenience schedule and place of vaccination. Conclusions: More than two-thirds of the respondents had knowledge about tetanus toxoid immunization before the start of their reproductive life but only half of them were completely vaccinated. Mass media found to be the main source of information. So planners and policy-makers should utilize mass medium and gear up the activities of health workers to convey the correct massages regarding tetanus toxoid immunization to its clients.

Dual effect of cytokinene on root-nodule bacteria and their host legumes, in relation to their symbiosis

The stimulatory effect of cytokinene was also reflected on the growth parameters of the legume plants, measured by the length of roots and stems and dry weight of shoots. This effect was most intensive at the combined treatment of with specific rhizobia. The bioassay test using barley as test plant, also revealed that cytokinene extracted from liquid culture media, of different species of rhizobia, had a positive effect on the retension of chlorophyll by the first leaves of test plant. Rhizobium, leguminosarum was the most effective strain in this respect

Relationship between curled root hairs and nodulation on legume plants in relation to symbiotic N2 fixation and amino acids synthesis

Results showed a positive significant correlation between the curled root-hairs and the number as well as their weight [mg/plant], after 20 and 75 days of sowing, respectively. Nitrogen fertilization [0.3 Ng/pot] in combination with superphosphate [0.50 g/pot] showed the highest increase in percentage of nodules. Glutamic and aspartic were the predominant amino-acids assimilated by the bacterioids in nodules and in the roots of legume plants under study. However, Faba bean showed the highest quantities of these amino acids as well as higher nitrogen content

Comparative study of the analeptic-respirogenic agents doxapram HCl and nikethamide: I - the acute toxicity and analeptic activity in mice

LD50 determinations showed that both Doxapram HCl and Nikethamide fall in the category of moderate toxicity; but Doxapram HCl was the less toxic. Assessment of the arousal capacity of Doxapram HCl against sleeping doses of pentobarbitone sodium in mice demonstrated that the drug has a high therapeutic index. Assessment of the restorative activity of Doxapram HCl and of Nikethamide against toxic doses of pentobarbitone sodium as percentage survival in mice, demonstrated the higher potency of Doxapram HCl
