Hospitals are a release source of many chemical compounds in their wastewaters. In the present study Salmonella typhimurium strains TA 98, TA 100 and TA 102 were analyzed for their sensitivity to hospital waste waters. The results of the study showed that hospital waste waters consists of mutagens causing frame shift mutations and base pair substitutions and amongst the three strains used in this study, TA 102 was most effective which along with TA 98 can be used for quick assessment of genotoxicity of hospital waste waters prior to its discharge. Genotoxic potential of hospital waste waters from five major hospitals located in Jaipur and Delhi was studied. Such waste waters should be treated prior to their discharge. The results of this study call for further detailed study in this area of research. [ABSTRACT FROM AUTHOR]

Study design:Randomized study.Objectives:To find out the incidence of deep vein thrombosis (DVT) in acute spinal cord injury (SCI) patients with and without therapeutic prophylaxis.Setting:Patients admitted in the department of Physical Medicine & Rehabilitation, SMS Medical College, Jaipur, India.Methods:All 297 patients received physical therapy measures and were randomly divided into two groups. 166 patients received prophylactic heparin, whereas 131 patients did not.Results:A total of three cases (1.8%) in study group and four cases (3%) in control group developed DVT. This difference was statistically insignificant (P>0.05).Conclusion:Incidence of DVT in SCI is low in our study. [ABSTRACT FROM AUTHOR]
