evolution and development of the outer acrosomal membrane (oam) and evidence that acrosin-inhibitors are proteins of the antiserum to the purified porcine outer acrosomal membrane (oam) was raised in rabbits and the igg fraction isolated by ammonium sulphate precipitation and ion exchange chromatography. the antibodies reacted exclusively with the acrosomal cap of the sperm head as revealed by indirect immunofluorescence. in addition they cross-reacted not only with the acrosomal part of the spermatozoa of all mammalian species tested (bull, horse, rabbit, rat, mouse, hamster, mole, antelope, monkey, man) but a ...19872446533
killing of human tumor cells by antibody c3b conjugates and human potentiate the lytic action of complement on tumor cells, we have constructed heteroconjugates composed of monoclonal antibody and of the human c3b component of complement. the conjugates were formed efficiently using the heterobifunctional cross-linking reagent spdp. the monoclonal antibody-c3b conjugate promoted the killing of k562 tumor cells by normal human serum. treatment of the tumor cells with the monoclonal antibody and normal human serum resulted in 10-15% lysis. however, following ...19892519543
enzyme polymorphism and clinical variability of diseases: a study of diabetes mellitus.we investigated possible relations among four common neonatal manifestations of diabetic pregnancy (macrosomia, hypoglycemia, hypocalcemia, jaundice) and four enzyme polymorphisms (pgm1, ada, ak1, acp1 in a sample of infants born of diabetic mothers. the pattern of associations observed between the two sets of variables is consistent with known differences in enzymatic activity within phenotypes of each system, suggesting that low enzymatic activity may have unfavorable effects on fetal developm ...19892556341
[acute maternal anterior poliomyelitis in a non-endemic zone].the authors report the case of a 26 year old woman with acute anterior poliomyelitis contracted during the vaccination of her baby. despite having been herself vaccinated in infancy she was not protected against the poliovirus. the clinical interest of this uncommon case is a severe paralytic state with definitive paraplegia. the authors suggest serologic testing of patients born before 1967 especially if they are at risk of encountering the virus.19892561040
epidemic of lav/htlv iii infection in drug addicts in milan: serological survey and clinical follow-up.a clinico-epidemiological study is reported concerning a group of 306 parenteral drug addicts (pdas), 71 of whom were affected with the lymphadenopathy syndrome (las); all were followed-up between 1981 and 1984. although full-blown acquired immune deficiency syndrome (aids) was observed only in one case, none of the other patients examined have undergone complete recovery so far. the results of our study point to a wide circulation of lav/htlv iii among our group of pdas, starting at least as ea ...19852999002

structural and functional studies of the effects of sympathetic nerve stimulation on rabbit submandibular salivary glands.continuous sympathetic stimulation at 8-10 hz caused intense vasoconstriction in the gland, so stimulation was generally given in an interrupted pattern to minimize this detrimental effect on secretion. only a small increase in fluid secretion occurred; it became thick and tended to block the cannula; therefore in later experiments the main duct was not cannulated. after sympathetic stimulation there was substantial degranulation of acinar cells. however, as this was accompanied by little moveme ...19883165262
role of postnatal gonadal function in the determination of thyrotropin (tsh) releasing hormone-induced tsh response in adult male and female rats.permanent effects of postnatal gonadal function on the hypothalamo-pituitary-thyroid axis were examined in male and female rats of the wistar-imamichi strain. animals were used at the age of about 10 weeks. neonatally castrated (nc) males showed a significantly higher plasma tsh response to trh (10 micrograms/kg bw, ip) than males castrated at 1, 2, 3, 4, or 6 weeks of age. the tsh response in intact males was similar to that seen in nc males. neonatal androgenization of nc males with 100 microg ...19873032567
