The purification of the pregnancy zone protein by means of immunoadsorbents is described. The pregnancy zone protein antibody was isolated from an absorbed rabbit antiserum and coupled with CNBr-activated sepharose. The pregnancy zone protein was isolated from pregnancy serum by the specific antibody cross-linked with sepharose. Contaminating serum proteins were eliminated by "inverse" immunoadsorption using antibodies against these proteins coupled with sepharose. An immunoelectrophoretically pure pregnancy zone protein was obtained. By means of a combination of immunoprecipitation and enzyme reaction in agar gel could be excluded that the pregnancy zone protein possesses activities of the following 11 enzymes: ceruloplasmin, leucine amino peptidase, alkaline phosphatase, carboxylic esterase, lactate dehydrogenase, malate dehydrogenase, glycerophosphate dehydrogenase, glucose-6-phosphat-dehydrogenase, cholinesterase, acetyl cholinesterase and oxytocinase.

Analysis of 25 plasma proteins was performed on blood drawn from 7 females before and during treatment with danazol. This steroid was found to induce a pattern of plasma protein changes similar to but not identical with that of other 17 alpha-alkylated anabolic steroids. For comparison, the same 25 plasma proteins were analyzed in blood from pregnant women in their third trimester, when the estrogen influence on plasma protein synthesis is most pronounced. Five major types of response were found. 1) Albumin and orosomucoid were not influenced by danazol or, after correction for volume expansion, by pregnancy. 2) Prealbumin, C1-esterase inhibitor, and haptoglobins increased substantially during danazol treatment but were not significantly influenced by pregnancy. 3) Transferrin, antithrombin III, prothrombin, and plasminogen showed marked increases after administration of danazol and during pregnancy. 4) Transcortin, ceruloplasmin, and alpha 1-antitrypsin doubled in pregnancy but were not influenced by danazol. 5) The concentrations of T4-binding globulin, pregnancy zone protein, and sex hormone-binding globulin more than doubled in pregnancy, and all three decreased to one third or less on administration of danazol. The plasma estradiol content fell correspondingly. The different types of plasma protein response found in these two groups of patients fit the hypothesis that hepatocytes contain steroid receptors capable of reacting with estrogens and/or other steroids such as danazol and, thus, influence the biosynthetic rate of many but not all plasma proteins according to a specific pattern. The synthesis of some of the estrogen-sensitive proteins is depressed after intake of danazol, which suggests that there is a competition for the receptors in the hepatocytes as there is for other estrogen target tissues.

Heterogeneity of haemoglobin, albumin, transferrin, esterase, alkaline and acidic phosphatases, haptoglobin, post-albumin, ceruloplasmin, carboanhydrase was studied in 1501 standard and colour minks by means of starch gel electrophoresis. Only the last three proteins of the enumerated ones have hereditary variations. Frequencies of the "main" allels of these systems are not lower than 0.9 and the average heterozygosis is 0.023.

Blood samples from 509 Macushi and 623 Wapishana Amerindians of of Northern Brazil and Southern Guyana have been analyzed with reference to the occurrence of rare variants and genetic polymorphisms of the following 25 systems: (i) Erythrocyte enzymes: acid phosphatase-1, adenosine deaminase, adenylate kinase-k, carbonic anhydrase-1, carbonic anhydrase-2, esterase A1,2,3, esterase D, galactose-1-phosphate uridyltransferase, isocitrate dehydrogenase, lactate dehydrogenase, malate dehydrogenase, nucleoside phosphorylase, peptidase A, peptidase B, phosphoglucomutase 1, phosphoglucomutase 2, phosphogluconate dehydrogenase, phosphohexoseisomerase, triosephosphate isomerase and (ii) Serum proteins: albumin, ceruloplasmin, haptoglobin, hemoglobin A2 and transferrin. Fifteen different rare variants were detected, involving 11 of these systems. In addition, a previously undescribed variant of ESA 1,2,3 which achieves polymorphic proportions in both these tribes is described. Excluding this variant, the frequency of rare variants is 1.1/1000 in 12510 determinations in the Macushi and 4.7/1000 in 15396 determinations in the Wapishana. The ESA 1,2,3 polymorphism was not observed in 382 Makiritare, 232 Yanomama, 146 Piaroa, 404 Cayapo, 190 Kraho and 112 Moro. Irregularities in the intratribal distribution of this polymorphism in the Macushi and Wapishana render a decision as to the tribe of origin impossible at present. Gene frequencies are also given for previously described polymorphisms of 5 systems: haptoglobin, phosphoglucomutase 1, erythrocyte acid phosphatase, esterase D, and galactose-1-phosphate-uridyl-transferase.

We have developed a modified solvent/detergent (S/D) treatment to inactivate viruses in human plasma using 1% w/w final concentration of tri(n-butyl) phosphate (TNBP) and Triton X-100 and an incubation period of 4 h at 30 degrees C. The procedure inactivates > or = 10(6) chimpanzee-infectious doses (CID50) of HBV, > or = 10(5) CID50 of HCV, and > or = 10(6.2) tissue culture infectious doses (TCID50) of HIV. After virus inactivation, eleven plasma batches were lyophilized and 12 batches were deep-frozen until further use. The batches were characterized by extensive laboratory tests including measurement of clotting factors I-XIII, von Willebrand factor, plasminogen, inhibitors of blood coagulation and fibrinolysis, and other clinically important plasma proteins. All parameters were determined before and after S/D treatment. Twelve conventional single donor plasma units served as control. There were no marked losses of activities of clotting factors, antithrombin III, protein C, plasminogen, and C1-esterase inhibitor due to treatment. After the S/D step, the levels of these parameters were within the normal range in all batches. The same holds true for total protein, immunoglobulins, albumin, complement factors C3 and C4, haptoglobin, hemopexin, caeruloplasmin, alpha 1-antitrypsin, and pH. Protein S and alpha 2-antiplasmin activities decreased by about 50% and were frequently found to be slightly below the lower limit of the respective normal range after treatment. The interindividual variations of all proteins analysed were significantly lower than in the single donor plasma units. The S/D procedure did not lead to increases of markers indicating activation of hemostasis.(ABSTRACT TRUNCATED AT 250 WORDS)

The genetic structure of two Chukot Evens subpopulations (314 individuals) for electrophoretic protein systems and taste sensitivity to PTC was studied. 17 of the 39 loci were polymorphic (43.59%). The following systems were completely monomorphic: diaphorase NAD H (Dia); glucose-6-phosphate dehydrogenase (G-6-PD); glutamatoxalate transaminase (GOT); carbonic anhydrase (Ca-1); catalase (Ct), lactate dehydrogenase (loci LDH-A and LDH-B); leucine aminopeptidase (Lap); malate dehydrogenase (MDH); purine nucleoside phosphorylase (PNP); superoxide phosphorylase (PNP); superoxide dismutase (SOD); phosphoglucomutase-2 (PGM2); cholinesterase (locus E1); red cell esterase (4 loci); albumin (Alb); hemoglobin (Hb A and B); ceruloplasmin (Cp); and blood, gren, using the standard method. The following systems were polymorphic: red cell acid phosphatase (AcP); phosphoglucomutase-1 (PGM1); 6-phosphogluconate dehydrogenase (PGD); glutamatepyruvate transaminase (GPT); glyoxalase-1 (GLO-1); esterase (EsD); adenilatkinase (AK); alkaline phosphatase (Pp); cholinesterase (locus E2); haptoglobin (Hp); transferrin (Tf); group-specific component (Gc) and ABO, MN, Lewis, P blood groups and taste sensitivity to PTC. The following allele frequencies for polymorphic loci have been detected: AKI = 0.994; GLO = 1I = 0.082; GPT1 = 0.653; AcPA = 0.400; AcPB = 0.599; AcPC = 0.001; PGDA = 0.944; PGM1(1) = 0.906; EsD1 = 0.897; E2+ = 0.048; HpI = 0.394; GcI = 0,919; Tfc = 0.987; r(O) = 0.669; p(A) = 0.184; q(B) = 0.146; M = 0.711; Le = 0.411; P1+ = 0.521; t = 0.295. The genetic structure of Chukot Evens population is significantly nearer to that of the other ethnic groups of the North-East, in comparison with the genetic structure of Evenks of the Middle Siberia.

Alkaline phosphatase (Alp), esterase-I (Es-I), esterase-II (Es-II), carbonic anhydrase (CA), cell esterase (cEs), esterase-D (Es-D), isocitrate dehydrogenase (ICD), malate dehydrogenase (MDH), 6-phosphogluconate dehydrogenase (PGD), tetrazolium oxidase (To), ceruloplasmin (Cp), Haptoglobin (Hp) and hemoglobin (Hb) in 58-75 samples of three species of tamarins (Saguinus mystax, S. labiatus and S. oedipus) were detected by means of horizontal starch gel electrophoresis. Two types (Es-I 1 and Es-I 2) for Es-I, four types (Es-II 1, Es-II 2, Es-II 3 and Es-II 2-3) for Es-II, three types (cEs 1, cEs 2 and cEs 1-2) for cEs, three types (PGD 1, PGD 2 and PGD 1-2) for PGD, two types (To 1 and To 2) for To, and three types (Hp 3, Hp 1-3 and Hp 2-3) for Hp were observed. However, Alp, CA, Es-D, ICD, MDH, Cp and Hb were monomorphic. In the S. mystax, no Es-II or PGD variants were observed. No Es-II variant was seen in the S. oedipus. Gene frequencies of cEs, PGD and Hb were biased in the three species. It is concluded that six polymorphic loci are useful as genetic markers for a species or individual.

The synthesis of gammaG, gammaA, gammaM, beta(1C)/beta(1A), C'1 esterase inhibitor, ceruloplasmin, transferrin, hemopexin, haptoglobin, fibrinogen, alpha(1)-antitrypsin, orosomucoid, beta-lipoprotein, alpha(2)-macroglobulin, and prealbumin was studied in 15 normal human embryos and fetuses of 29 days to 18 wk gestation and in the yolk sacs of four embryos from 5.5 to 11.5 wk gestation using tissue culture in (14)C-labeled amino acids followed by radioimmunoelectrophoresis. The human embryo as early as 29 day gestation synthesized beta(1C)/beta(1A), C'1 esterase inhibitor, transferrin, hemopexin, alpha(1)-antitrypsin, beta-lipoprotein, alpha(2)-macroglobulin, and prealbumin in culture. At 32 days gestation ceruloplasmin and orosomucoid were also synthesized, but synthesis of fibrinogen was not observed before 5.5 wk. Synthesis of gammaM occurred as early as 10.5 wk gestation, and gammaG synthesis was found in cultures as early as 12 wk gestation; gammaA synthesis was not detected in any of the tissue cultures. With the exception of the gamma-globulins, each of the proteins studied was synthesized by the liver, but additional sites of synthesis for some of these proteins were also found. Synthesis of gammaG and gammaM occurred primarily in the spleen, but other sites of synthesis were noted as well. Changes in the concentrations of most of these proteins and plasminogen in embryonic and fetal serum from 5.5 to 41 wk gestation, in amniotic fluid from 6.5 to 38 wk gestation, and in the sera of neonates during the 1st 3 wk postpartum are described. Although gammaA, gammaM, ceruloplasmin, or haptoglobin were not detectable in some of the embryonic and fetal sera, gammaA and ceruloplasmin were both present as early as 6.5 wk gestation, haptoglobin by 9.5 wk gestation, and gammaM by 17 wk gestation. Each of the other proteins were present in all of the sera examined.

The genetic structure of three Asiatic eskimos subpopulations (402 individuals), five coast chuckchies subpopulations (1793 individuals) and three reindeer chuckchies subpopulations (559 individuals) have been studied for 26 electrophoretic protein systems (33 loci). These are: adenilate-kinase (AK), diaphorase NAD X H (Dia), glyoxalase-1 (GLO-1), glucose-6-phosphate dehydrogenase (6GPT), glutamatpyruvate transaminase (GPT), glutamicoxalate transaminase (GOT), carbonic anhydrase-1 (Ca-1), catalase (Ct), acid phosphatase (AcP), lactate dehydrogenase (loci LDH-A and LDH-B), leucine aminopeptidase (Lap), malatedehydrogenase (MDH), purine nucleoside phosphorylase (PNP), superoxide dismutase (Sod), 6-phosphogluconate dehydrogenase (PGD), phosphoglucomutase (loci PGM1 and PGM2), cholinesterase (loci c1--c5), alkaline phosphatase (Pp), esterase D (EsD), red cell esterase (Est) - 4 loci, albumin (Alb), haptoglobin (Hp), hemoglobine (Hb A and B), group-specific component (Gc), transferrin (Tf), ceruloplasmin (Cp). In addition, AB0 and Rh system blood groups and phenyl thiocarbamide taste sensitivity (PTC) have been studied. 12 of 36 loci are polymorphic (33.33%), heterozygosity for all loci in eskimos, coastal and reindeer chuckchies being 0.118 +/- 0.005, 0.130 +/- 0.002 and 0.120 +/- 0.004, respectively. These estimates do not differ essentially from heterozygosity at these loci for mongoloid groups living further south. The test for interpopulation heterogeneity has permitted to estimate contribution of the loci to the differentiation of these populations. The least heterogeneity has been found at loci where gene frequency distribution is the most specific for these ethnic groups.
