6.The Effect of Uremic Plasma on the Proliferative Activity of CFU-GM in in-vitro Culture of Mouse Bone Marrow.
Korean Journal of Pathology 1987;21(4):215-226
The increased susceptibility in patients of chronic renal failure to infection has been reported to be attributed to defects in granulocyte and lymphocyte function and proliferative activity of hematopoietic cells. The definite cause of the frequent infection in uremic patients, however, is still controversial. The effect of uremic plasma on the aspect of the hematopoietic cells has been scarcely been studied. In the present study, mouse bone marrow was cultured with uremic plasma, to evaluate the effect of uremic plasma on the proliferative activity and morphological features of CFU-GM. The results obtained were as follows. 1) The number of colonies in group co-cultured with uremic plasma was more reduced than that of normal plasma group. 2) There was no difference between the group cultured with predialytic uremic plasma and that of postdialytic plasma in number of colonies, macroclusters and microclusters. 3) The forms of colony were granulocytic and monocytic forms at 5 day of culture. Electron microscopically, granulocytes disclosed electron dense azurophilic granules and electrolucent specific granules in the cytoplasm, and monocyte showed numerous vesicles and vacuoles in the cytoplasm which had finger-like projections. 4) The molecular weight of inhibitory factor in the uremic plasma was supposed to be less than 50,000 daltons.

In 1970, Boutine introduced a alumina ceramic for cemented total hip replacement . A ceramic articulation thought to be superior to metal on polyethylene due to its extremely low coefficient of friction and its potential for resistance to wear. Mechanical failure of ceramic femoral head is rare. We report a case of fracture of ceramic femoral head, which occured after implantation of uncemented total hip replacement.

Mutation of the p53 gene frequently results in overexpression of the p53 protein and loss of its tumor-suppressing properties. The overexpression of the p53 gene could be an indicator of rapid proliferation, poor differentiation, advanced stages, or poor prognosis. The prognostic value of the overexpression of the p53 gene in colorectal carcinoma is equivocal. The presence of DNA aneuploidy has been described as a powerful adverse prognostic indicator in relation to survival. To investigate the prognostic significance of p53 expression, and the relationship with DNA ploidy, 92 cases of colorectal carcinomas were analyzed. The overexpression of p53 gene product was present in 50(54.4%) of 92 cases. p53 expression only correlated with recurrence or metastasis during the follow-up periods (p=0.045). DNA aneuploidy was observed in 32(39.1%) of 82 cases. DNA ploidy was strongly associated with lymph node invasion(p=0.005), Dukes' stage(p=0.003), TNM classification (p=0.003), and recurrence or metastasis during the follow-up periods (p=0.045). The frequency of DNA aneuploidy was higher in the p53-positive colorectal carcinomas(58.3%) than in the p53-negative colorectal carcinomas (21.6%) (p=0.003). p53-positive colorectal carcinomas had a higher rate of cell proliferation than p53-negative cases(p<0.001). These results suggest that checking the p53 expression and DNA ploidy could be useful prognostic indicators of colorectal carcinoma.

The clinical role of tumor markers to detect the extent of tumor invasion and recurrence in cervical cancer has been debated. To evaluate the chncal significance of SCC, CEA and TPA as tumor markers in cervical, we studied 744 patients weith cervieal cancer from June 1990 to Mey 1994. The cut-off val ues of SCC, CEA and TPA were 1.5 ng/ml, 4.5 ng/mi and 110 U/I respectively. Followings were the results. 1. The serum concentration and positive rates of SCC before therapy(567 cases) were 3,0+/-7.0ng/ml(40.4%) for stage I,8.7+/-13.9 ng/ml(71.6%) for stage II, 10.8+/-14.7 ng/ml(85.7%) for stage III, 23.9+/-24.3 ng/ml(94.7%) for stage IV, and 13.4+/-19.1 ng/ml(75.0%) for recurrent cancer. It was increased with advancing clinical stage(p<0.01). 2. The seum levels and positive rate of CEA before therapy(627cases) were 3.4+/-4.3 ng/ml (18%) for stage I, 7.1+/-12.3 ng/ml(37.2%) for stage II, 8.4+/-9.6 ng/ml(57.9%) for stage III, 15.4+/-22.2 ng/ml(52.6%) for stage IV, and 10.3+/-16.2 ng/ml(46.4%) for recurrent cancer. It was increased with advancing clinical stage from stage Ito stage III(p<0.01). 3. The serum concentration and positiceive rate of TFA before therapy(301cases) were 51.7+/-53.8 U/l(9.5%) for stage I, 105.3+/-108.8 U/l(32.3%) for stage II, 186.3%+/-159.8 U/l(50%) for stage III, 191.3+/-l06.2 U/I(63.6%) for stage IV, and 135.4+/-117.0 U/l(46.4%) for recurrent cancer. It was increased with advencing clinical stage(p<0.01). 4. In 64 patients{24.2%) with lymph node invasion of 265 patients treated by operation, the mean serum levels of SCC, CEA and TPA were higher than lymph node negative group(p<0.05). 5. The serum levels of SCCand CKA after therepy were 82.8% in sensitivity. 94.3% in specificity, 67.9% in positive predictive value, 97.4% in negative predictive value.
