Immunolocalisation of the glutathione S-transferases, GST-26 and GST-28, within adult Schistosoma japonicum

This paper describes the first ultrastructural immunolocalisation study of the 26-kDa and 28-kDa glutathione S-transferases within adult Schistosoma japonicum (GST-26 and GST-28). Polyclonal antibodies raised against GST-28 (in mice) and against GST-26 (in rabbits) were used to examine the distribution of the proteins within adult parasites. Both proteins were localised within the parenchymal region of the male parasite. Additionally, both proteins were present within parenchymal cells located between the vitelline glands of female parasites. There were no detectable levels of GST-26 or GST-28 on the surface or within the tegument matrix of either the male or female worms. Possible functions for GST-26 and GST-28 within S. japonicum and their significance as vaccine target molecules are addressed.     

Perception and practice regarding pulse polio immunisation in an urban community of Calcutta

A survey was conducted at an Integrated Child Development Services (ICDS) Scheme project in North Calcutta among 656 mothers having children less than 3 years of age to assess their perception and practice regarding pulse polio immunisation (PPI). It was revealed that 91.8% of under 3-year children received PPI on 9-12-1995 and 94.4% on 20-1-1996. Major reasons for not accepting the services on those two days included 'mothers unaware' (22%), 'child too small' (30.5%), etc. Major source of first information was television (TV)/radio (57.2%) followed by anganwadi workers (AWWs) (33.8%). However, majority of the mothers were finally motivated for PPI by AWWs (58.8%) followed by the role of TV/radio (34.1%). Although 70.7% mothers knew the name of the vaccine correctly, only 3.5% mothers could tell the exact purpose of its administration. Most mothers (73%) opined that 2 drops of oral polio vaccine (OPV) was administered to their children and only 14.6% hoped that such programmes will be conducted by the Government in future. The average waiting time of mothers at immunisation centres was found to be 7.2 minutes.     

Limitations in upper-body strength associated with breast cancer: a comparison of black and white women

We examined differences in reported upper-body limitations between black and white breast cancer cases and controls aged 40 to 84 years at 3 and 12 months after diagnosis in the Detroit metropolitan area (n = 954 cases and 1000 controls at 3 months; n = 879 cases and 909 controls at 12 months). At 3 months black cases were more likely than white cases to report limitations in upper-body strength (30.4 versus 19.8%). No difference was found between black and white controls (8.0 versus 9.4%). At 12 months, the proportion of white patients with upper-body limitation returned to the same level as white controls. Black patients with limitations, however, did not return to the same level as black controls. Stage of disease was strongly associated with upper-body limitations, especially for black women. Race and stage differences in upper-body limitation could not be explained by differences in breast cancer treatment, financial adequacy, education, marital status, or comorbidity. Recommendations are made for more comprehensive studies of rehabilitation.
