hypertension during pregnancy, with and without specific hypotensive treatment. i. perinatal factors and neonatal morbidity.	in a prospective study, women who were hypertensive before the 28th wk of gestation were randomly allocated into two groups: those who received specific hypotensive therapy (ht) and those who did not (hu). the outcome was compared with a random sample of the hospital population (s) ascertained after delivery. in both hypertensive groups there was a higher incidence of clinical signs of possible fetal distress and instrumental delivery. although there was no difference between the groups in the d ...	1990	551921
radiation methods in agriculture.	on the basis of fundamental investigations in radiobiology, numerous methods of using ionizing radiations in agricultural practice have been proposed. the current status of the problem, on the basis of basic, semi-production and industrial-scale tests of the suggested methods, is described. we conclude that there is now a satisfactory, economically viable radiation-biology technology. for wide introduction of this technology into agricultural practice, governmental decisions concerning the produ ...	1990	551821
effect of phospholipids on purified lipoamidase.	phospholipids were added to purified lipoamidase from porcine brain microsomal membranes, and changes in lipoamidase activity were examined. approximately twofold activation of lipoamidase activity occurred upon the addition of phosphatidylethanolamine. on the other hand, phosphatidylserine, cardiolipin, and phosphatidic acid reduced the enzyme activity by approximately 80%. this pattern of the activation of lipoamidase by phosphatidylethanolamine and its inhibition by phosphatidylserine is simi ...	1990	2347395

human keratinocytes are a source for tumor necrosis factor alpha: evidence for synthesis and release upon stimulation with endotoxin or ultraviolet light.	tumor necrosis factor alpha (tnf-alpha), in addition to being cytotoxic for certain tumor cells, has turned out as a multifunctional cytokine that is involved in the regulation of immunity and inflammation. since human keratinocytes have been demonstrated to be a potent source of various cytokines, it was investigated whether epidermal cells synthesize and release tnf-alpha. supernatants derived from normal human keratinocytes (hnk) and human epidermoid carcinoma cell lines (kb, a431) were teste ...	1990	2258696
radioimmunotargeting of human tumour cells in immunocompetent animals.	a tumour model system is reported that for many purposes may be an alternative to xenografted nude mice. the model allows immunotargeting of human tumour cells in immunocompetent animals. the target cells are contained in i.p. diffusion chambers (dc) with micropore membrane walls that are permeable to molecules, including the cell specific monoclonal antibodies (moab), but impermeable to cells. thus, the tumour cells are protected from the host immunocompetent cells. in the work here presented t ...	1990	2223574
