{"title":"A pilot study on universal immunization of newborn infants in an area of hepatitis B virus and primary hepatocellular carcinoma prevalence with a low dose of hepatitis B vaccine.","authors":"T T Sun, Y R Chu, Z Q Ni, J H Lu, F Huang, Z P Ni, X F Pei, Z I Yu, G T Liu","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Hepatitis B virus (HBV) had been considered as the main causative factor of primary hepatocellular carcinoma and universal immunization of newborns was recommended as the major approach to control hepatitis and hepatoma in areas of prevalence. As the initial phase of the first vaccination program for such a purpose, a pilot study was done from September 1983 to May 1984 in a high incidence rural area of China. In an area of 214,343 inhabitants, 1,703 newborns (99% of all births) were vaccinated. Ninety-seven percent of all vaccinees were followed up at 1 year. The vaccine used was Hep-B Vax, given intramuscularly at 0, 1, and 6 months after birth. Four immunization regimes were used: 5-micrograms or 2.5-micrograms doses with or without hepatitis B immune globulin (HBIG) added in the case of carriers children. These groups were defined by drawing lots at community level. A matched control was selected on a voluntary basis. Each group consisted of 400 infants. Vaccination was proven to be very safe and well accepted by the public. The prevalence of HBV infection in the area was further demonstrated by the high HBsAg-positive rate measured: 14.2% of the 1,180 mothers (3.9% were also e-antigen positive), 7.6% and 10.1% of the unvaccinated children at 6.5 months and 1 year of age, respectively. It was shown that vaccination with a 5-micrograms or 2.5-micrograms dose significantly lowered the HBsAg positives to a level close to 1.5% versus 10% in the control group at 1 year. An 85% protection was thus achieved. A 5-micrograms dose plus HBIG did not show additional benefit. A 2.5-micrograms dose plus HBIG gave less protection, and anti-HB levels were also significantly lower than in other groups. Among the 12 failures found in the 5-micrograms and 2.5-micrograms groups, 11 were born to HBsAg-positive mothers, nine of whom also had e-antigen. Available data showed that 29% of children born by e-antigen-positive and 2.7% of children born by e-antigen-negative carriers had the risk of becoming carriers during the first year of life following vaccination. The present study demonstrated the feasibility and rationale of conducting universal immunization of newborns in endemic rural area for controlling hepatitis and hepatoma. The significance of the possible use of the vaccination at lower dose had also been stressed.</p>","PeriodicalId":77735,"journal":{"name":"Journal of cellular physiology.

Human N-ras gene was identified in transfectants from 7402 DNA and transformed cells from three PHC DNA samples, which had passed more than two cycles of transfection. The expression of N-ras was also remarkably enhanced in six out of nine poly(A)+RNA samples isolated from PHC tissues. P21 synthesis was elevated in 7402 cells as well as in transfectants derived from 7402 cells and PHC DNA. In analysis of PHC DNA, rearrangement and amplification of N-ras gene was observed in two PHC samples. The discrepancy of results of the transfection assay and mRNA expression was discussed. Furthermore, c-myc was also highly expressed in most PHC tissues. It implied that the cooperating activity of N-ras and c-myc might be responsible for the malignant phenotypic alteration in some or most cases in human primary liver cancer.</p>","PeriodicalId":77735,"journal":{"name":"Journal of cellular physiology.

The strong signal of smear comparing with NIH 3T3 DNA as control was observed. It was implied that the putative human transforming sequences had been integrated into transformed cells. Employing soft agar culture, the transformed cells can grow and form cell colonies. Following transfer, the foci were able to grow and adhere to a glass wall. These cells were easily agglutinated by con A. The cloned foci have been inoculated into nude mice with the formation of highly malignant sarcomas. In preliminary experiments for characterizing the transforming sequences, Ha-ras and Blym 1 were found in transfectants derived from one of the NPC DNA samples. It is implicated that these two oncogenes might be responsible for the acquisition of malignant phenotypic character of some human NPC.
