LDH isoenzymes and heat-stable alkaline phosphatase were studied in the serum and placental extract of 20 cases of pre-eclampsia and 10 normal pregnancies as a control. The starch-gel electrophoretic serum and placental isoenzymogram showed that LDH4 and LDH5 were the main isoenzymes in the placenta while LDH1 and LDH2 were the main isoenzymes in the serum in pre-eclampsia. The electrophoretic serum protein pattern in pre-eclamlobulins with decreased albumin fraction, while in the placenta, the albumin fraction was increased together with a decrease in the alpha-globulins. The electrophoretic pattern of serum alkaline phosphatase showed a main band of activity at the B-globulin zone in all cases of normal pregnancy and pre-eclampsia. In the placenta, two additional bands were detected.

The nephrotoxicity of ribostamycin and gentamicin was compared by urinalysis using 18 parameters. When a dose of 40 mg/kg per day was administered intramuscularly to Fischer rats for 14 days, ribostamycin caused little change of parameters in urine volume, urine osmolality, urine protein, maltase and beta 2-microglobulin. A slight increase with ribostamycin was observed in alpha-fucosidase, beta-N-acetylglucosaminidase, leucine aminopeptidase, lactic dehydrogenase (LDH) and potassium, and a moderate increase was observed in acid phosphatase and alkaline phosphatase. On the other hand, gentamicin caused a large alteration in most parameters. Both antibiotics caused a change of the isoenzyme pattern of LDH1-5, but the pattern with ribostamycin was much closer to the normal pattern than with gentamicin. When a dose of 80 mg/kg of ribostamycin was compared with 10 mg/kg of gentamicin, alteration of urinary parameters was almost comparable. Histopathological observations of the kidney specimens of rats given 40 mg/kg per day showed no histological damage with ribostamycin except for a slight increase and enlargement of lysosomes of the proximal epithelial cells. However, significant histological damage was observed with gentamicin, consistent with the results obtained from urinalysis. Renal accumulation of ribostamycin at a single dose of 20 mg/kg was three times less than that of gentamicin. Ribostamycin caused slightly less nephrotoxicity in rats than kanamycin and far less than dibekacin at an equal dosage of 40 mg/kg per day for 14 days.

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.

In order to establish sensitive methods of detecting minor renal damage, changes of enzymes, protein, tubular cell counts, and creatinine in the urine were investigated in rats to which nephrotoxic chemicals had been administered. Daily administration of p-aminophenol (PAP) dose-dependently increased urinary excretions of lactate dehydrogenase (LDH) and its isoenzymes (LDH5 = LDH4 greater than LDH3 greater than LDH2 = LDH1), aspartate aminotransferase (GOT), alkaline phosphatase (ALP), gamma-glutamyl transpeptidase (gamma-GTP), leucine aminopeptidase (LAP), lysozyme (LZM), N-acetyl-beta-D-glucosaminidase (NAG) and acid protease together with increased counts of tubular cells in the urine. Tubular cell counts, LDH and GOT were more sensitive indicators in the PAP tubulonephritis. Single i.v. injection of puromycin aminonucleoside (PM) dose-dependently increased urinary excretions of LDH and its isoenzymes (LDH1 = LDH5 greater than LDH2 = LDH4 greater than LDH3), GOT, NAG, acid protease and protein but degree of the increases in these enzymes was lower than those in the rats treated with PAP. PM increased excretions of high molecular weight proteins but did not increase ALP, gamma-GTP, LAP, LZM and tubular cells excretions. Single i.v. injection of hexadimethrine increased urinary excretion of LDH and its isoenzymes (LDH1 = LDH5 greater than LDH2 greater than LDH3 = LDH4), GOT, LZM, NAG and acid protease together with increased counts of tubular cells in the urine but did not increase ALP, gamma-GTP and LAP excretions. It is concluded that tubular cell counts, LDH isoenzymes and battery of these enzymes in urine are useful markers for detecting the severity and the site of renal damage in addition that urinary protein is a useful marker for detecting glomerular damage.

Mixed leukocyte suspensions were prepared from heparinized blood collected from healthy subjects and from patients with chronic myeloid leukemia (CML). In all the suspensions determinations were made for: zinc, by atomic absorption; granulocyte alkaline phosphatase (GAP), using the method with p-nitrophenylphosphatase; granulocyte LDH, by means of the enzymatic autoanalyser LKD 8,600. In the patients with CML, the values of zinc and of granulocyte alkaline phosphatase activity were very low while the granulocyte LDH values were higher than normal. The chromatogram of the granulocyte LDH isoenzymes on DEAE-Sephadex A50 minicolumn (0.5 X 12 cm) showed an "alpha type abnormality" revealed by the increased activity of the isoenzymes with high electrophoretic mobility LDH2 and LDH1 specific for tissues with intense oxidative phosphorylation. In the normal subjects the chromatogram of the leukocyte LDH isoenzymes showed a type M (skeletal muscle) prevalence denoting intense anaerobic glycolysis. Therefore the low zinc concentrations (0.55 micrograms mg N2 as compared with the normal 1.24 micrograms mg N2) in these patients cause the decrease of GAP activity by the lack of zinc in the active center of the enzyme and the decrease of cellular permeability thus allowing the extracellular release of granulocyte LDH.

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.

The isozyme patterns and activities of six enzymes were determined in surgical biopsy samples of lung tumors and non-neoplastic pulmonary areas. Fetal lungs were also examined. No tissue differences were found in the isozyme pattern of hexokinase or alkaline phosphatase; small differences in pyruvate kinase isozyme proportions were observed. The tumors exhibited significant deviations with respect to the lactate dehydrogenase (LDH) and malate dehydrogenase (MDH) isozyme patterns. Despite the diversity of cell types, the proportions of the M-subunit of LDH in each tumor and that of the mitochondrial isozyme of MDH in all but one tumor were higher than in control samples from the same lung. In contrast, the normal fetal lung showed a higher LDH-H proportion than did adult lung and a mature MDH isozyme pattern. The alpha-glycerophosphate dehydrogenase and adenylate kinase activities of the tumors were about one-tenth and one-fourth, respectively, of those of nonneoplastic adult lung. These lower activities (evident also in normal fetal lung) were accompanied by 3- to 5-fold increases in the LDH, MDH, pyruvate kinase, and hexokinase activities of the tumors; fetal lungs had lesser increases (2- to 3-fold) for the first 3 enzymes. The common features of tumors with different cell types and histological grade identified here point to several enzymes the quantitation or isozyme analysis of which may be of practical use in distinguishing cancerous from nonneoplastic human lung samples. A combination of different indicators, such as opposite changes in LDH and alpha-glycerophosphate dehydrogenase activity, coupled with elevated proportions of LDH-M, may be used to diagnose neoplasia most reliably.

Histochemical studies of myocardial biopsies from chronic chagasic patients at different evolutive stages showed a pattern primarily characterized by a marked increment in tissue enzymes such as mono-amine oxidase and lysosomal acid phosphatase. This cellular damage can be reflected by changes in certain serum enzymes associated with myocardial metabolism, specially in the coronary sinus, where the blood metabolized by the heart is drained. However, little is known about the possible changes in blood enzyme activity during chronic Chagas disease. In this investigation, the activity of the following enzymes glutamic-oxaloacetic transaminase (GOT), glutamic-pyruvic transaminase (GPT), alkaline phosphatase (ALP), acid maltase (AM), lactate dehydrogenase (LDH), alpha-hydroxybutyric dehydrogenase (alpha-HBDH or LDH1) and creatine phosphokinase (CPK) was measured in blood serum of the superior cava vein (SCV), coronary sinus (CS) and pulmonary (PA) and femoral (FA) arteries of 45 chronic chagasic patients, ages between 20 and 55 yr, at different evolutive stages (groups IA, IB, II and III). The results demonstrate that the average activity of the enzymes studied in chagasic patients, except LDH and CPK, are significantly altered (p < 0.05) in the majority of the arterial and venous blood samples. The finding of released GOT, GPT, ALP, acid maltase and alpha-HBDH in groups IA and IB is an indication of early myocardial damage in chronic chagasic patients without clinical evidence of cardiac disease. In conclusion, it is suggested that the possible evolutive pattern for myocardial damage could be established by the increment in coronary sinus blood of the enzymes GOT, acid maltase and alpha-HBDH.
