The importance of community's health followed by the consideration of endogenous growth models has led to an increase in health expenditure of countries to speed up economic growth and development. This has made the efficiency of health production function to an essential issue especially in developing countries. Based upon this, the present study with employing the stochastic frontier analysi...

Mechanisms for resistance were studied in three classic type, human small cell lung cancer cell lines, (.!(,,, (.I.(',„,and <;i.<',.i, that were established from one patient during clinical follow-up. Clinically the tumor changed from sensitive (<;!,(,,) to completely resistant to (chemo)therapy ((il.(.',,,) during this period. The stain with JSB-1 anti body, detecting the M, 170,000 multidru...

To elucidate the significance of tRNA modification for human lymphoid maturation and malignant transformation, the amount of tRNAs having guanosine in place of queuosine, i.e., (Q-)tRNA, was determined in several human lymphomas and leukemias by exchanging the respective unmodified guanosine residue for [3H]guanine, a reaction catalyzed by a specific tRNA transglycosylase from Escherichia coli....

Cholecystokinin (CCK) is a growth factor for normal pancreas. Nu merous studies also suggest that CCK promotes pancreatic carcinogenesis in the rat. Our previous studies suggested that growth of preneoplastic pancreatic foci was stimulated by CCK more than that of normal pan creas. We hypothesized that such differential growth might be due to increased numbers of CCK receptors in neoplastic tis...

Aims—To examine long term survival of women with primary and recurrent cervical carcinoma in relation to (1) excretion of â-core (a urinary metabolite of â human chorionic gonadotrophin (âhCG)) and (2) âhCG immunostaining of the tumours, to determine the suitability of these markers for assessing prognosis. Methods—This was a prospective observational study undertaken in a gynaecological oncolo...

The 0-24-h urinary metabolic profile of cyclophosphamide was inves tigated in a series of 14 patients with various malignancies receiving combination chemotherapy including i.v. cyclophosphamide. This was accomplished using combined thin-layer chromatography-photographydensitometry, which can quantitate cyclophosphamide and its four prin cipal urinary metabolites (4-ketocyclophosphamide, nor-ni...

Recently, evidence was reported for the belief that a carcinogenic agent, †̃20-methyleholanthrene, could be secreted into the milk of a lactating ani mal and thereby gain entrance into the bodies of the offspring to cause an abnormally high mci dence of neoplasms (1). Further positive evidence for this mode of excretion of methyleholanthrene has now been obtained by means of ultraviolet ab sor...
