An evaluation of routine immunization coverage in some districts of West Bengal and Assam.

A coverage evaluation survey was carried out in the five districts of West Bengal and Goalpara district of Assam during the period from November 2002 to April 2003 through 40 clusters sampling technique. Results revealed that highest coverage with routine immunization was in Paschim Medinipur (82.5%) followed by Kolkata (71.6%), Malda (65.3%), 24 Parganas South (61.9%) districts of West Bengal. Murshidabad district of West Bengal had only 41.3% coverage while poorest coverage was observed in Goalpara district (27.2%) of Assam. "Not aware of the need for routine immunization" was the main reason for not being vaccinated with all the UIP vaccines. Vaccination was given mainly through government hospitals in Kolkata while it was administered mainly through subcentres in the other rural districts.

Effect of antibiotics in controlling the production of cell wall degrading enzymes in vitro and disease development in vivo.

Production of cellulolytic, proteolytic and pectolytic enzymes by all the three isolates of A. niger was inhibited by all the tested antibiotics. Nystatin (500 ppm) could cause complete inhibition of PG enzyme production, whereas PMG production was checked by amoxicillin, nystatin, chloramphenicol and raficillin at 100 ppm concentration. All the antibiotics at 500 ppm concentration checked the cellulase production in all the three isolates of A. niger. Nystatin and raficillin (100 ppm) completely controlled the protease production in all the three isolates of A. niger. A positive correlation was observed with enzyme production and mycelial biomass in three isolates of A. niger, All the antibiotics at both the concentrations (100 and 500 ppm) could also check the rottening in all the three fruits in vivo conditions.

Women and HIV infection.

The pattern of the AIDS epidemic has recently changed with proportionately more women and children affected. Cases are becoming more widespread and heterosexual encounters are becoming an important means of spread of disease (presently 43% of all cases in the United States). Risks of contracting the virus depend upon sexual behaviors and the status of HIV disease in her partner. Manifestations of HIV infection are varied in women and include infections and cancer. Once the patient tests positive for HIV infection, she needs serial screening of blood counts, CD4 lymphocyte subsets and measurements of viral burdens. Antiretroviral therapy should be started when the CD4 count drops to under 500/d1, and prophylaxis against pneumocystis carinii and also for viral and mycobacterium avium infections when the CD4 count drops under 200/d1 and 100/d1 respectively. Pregnant women have a 25-33% risk of transmitting the disease to their fetus; this can be reduced through AZT treatment of the mother and of the baby after birth. Risk reduction through counseling about safer sex, e.g., abstinence, condom use, remains the best hope for protecting women against the HIV epidemic.
