The genetic structures of the population residing in the provinces of Venice and Rovigo in the Veneto region at the north of the Po delta in Italy was studied in 1,210 individuals residing in 18 sampling areas, using the phenotype and gene frequencies of 7 red cell enzymes: acid phosphatase (ACP1), esterase D (ESD), glyoxalase I (GLOI), glutamic-pyruvic transaminase (GPT), 6-phosphogluconate dehydrogenase (6-PGD), phosphoglucomutase 1 (PGM1), and phosphoglycollate phosphatase (PGP). For the analysis of the distributions of phenotype and gene frequencies, standardized variance and kinship profiles were used. It was found that the genetic differentiation within each province is low, and that only two systems, GPT and PGP, are significantly different between the two provinces. The samples studied seem to belong to a mainly homogeneous population.

Biochemical method was adopted to examine 10 kinds of histologic enzyme spectrum activities in gastric intestinal metaplasia, carcinoma and normal or superficial gastritis mucosa taken from different sites from 17 fresh surgical specimens of stomach. The enzymes are aldolase (ALD), pyruvate kinase (PYK), phospho hexo-isomerase (PHI), lactic dehydrogenase (LDH), creatine phosphokinase (CPK), hydroxybutyrate dehydrogenase (HBD), glutamic-pyruvic transaminase (GPT), alkaline phosphatase (AKP), acid phosphatase (ACP), r-glutamyl-transpeptidase (gamma-GT). Among glycolytic enzymes the content of ALD, PYK in intestinal metaplasia were 24.5 u and 24.6 u respectively, which were higher than those in the normal mucosa (15.7, 18.0) and lower than carcinoma (28.4, 29.6) (P less than 0.01-0.05). The content of CPK in intestinal metaplasia was lower (218.5 u) than that in the normal (463.9 u) and higher than that in carcinoma (110.3 u) (P less than 0.01). Among protease and amino acid enzymes the content of HBD in intestinal metaplasia was lower (108.2 u) than those in the normal (221.3 u) and carcinoma (113.9 u) (P less than 0.05). The content of GPT in intestinal metaplasia was (6.7 u) which was lower than that in the normal (9.4 u) and higher than that in carcinoma (3.7 u) (P less than 0.01). The above results could provide reference indices for judging the potential malignancy of gastric intestinal metaplasia.

The activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), acid phosphatase (ACP), lactate dehydrogenase (LDH) and isocitric dehydrogenase (ICD) in the serum of 60 healthy dromedary camels of either sex and different ages (one to 25 years) were determined. The results were analysed with respect to time of year (December-January and May-June), sex and age groups (below four years; four to 10 years; and over 10 years). The overall mean activities of AST, ALT, ALP, ACP, LDH and ICD were 36.1 +/- 0.35, 4.65 +/- 0.35, 27.21 +/- 0.43, 7.18 +/- 0.21, 479.0 +/- 7.33 and 7.74 +/- 0.17 iu litre-1, respectively. Activities of AST, ALT, ALP and ACP were significantly higher during extremely hot conditions (May-June) than in extreme cold (December-January) while the activity of LDH was higher in extremely cold conditions. Analysis of data based on sex revealed that AST, ALT and ALP activities in the serum of male animals were significantly higher than in female animals. The activities of all the enzymes were highest in animals under four years and then gradually decreased with age being lowest in the animals over 10 years.

1. Enzyme modulation by cadmium in selected organs of the fish, Barbus conchonius (rosy barb), was investigated in vivo (48 hr exposure to 12.6 mg/l cadmium chloride) and in vitro (10(-6) M cadmium chloride). 2. The acetylcholinesterase (AchE) activity was depressed in the gills but stimulated in the skeletal muscles and brain in vivo. The hepatic, branchial, and renal acid phosphatase (AcP) activity decreased marginally in vivo but it was significantly increased in the gut and ovary. In vitro, except for the liver, the AcP activity was depressed in the selected organs. Collaterally, gut alkaline phosphatase (AlP) was significantly inhibited but a pronounced stimulation was noted in the kidneys and ovary in vivo. In vitro, the AlP activity was conspicuously elevated in the kidneys and gut, and moderately in the gills. 3. Cadmium inhibited the glutamate-oxaloacetate and glutamate-pyruvate transaminases (GOT and GPT) in the liver, gills and kidneys in vivo. In vitro, the GOT and GPT activities were decreased in the liver, gills and kidneys. The lactic dehydrogenase (LDH) was significantly stimulated by Cd in the heart in vivo but in vitro the metal inhibited the enzyme in the gills. 4. Enzymes in the liver, followed by those in the kidneys and gills seem to be most seriously affected by Cd poisoning in this fish.

The hypocholesterolaemic effect of Cassia fistula was investigated using hypercholesterolaemic male albino rats. Hypercholesterolaemia was induced by feeding on a mixture of cholesterol plus cholic acid for a 12 weeks period. Hypercholesterolaemia was characterized by significant increase in the average levels of total lipids, total cholesterol, and triglycerides and significant decrease in phospholipids content. Administration of Cassia fistula significantly reduced blood and liver total lipids. Brain, spleen, kidneys and heart followed nearly the same trend but with moderate effect. Blood, liver, kidneys, spleen and heart total cholesterol was significantly reduced, while that of brain was not affected. The level of triglycerides was markedly improved. There was a moderate rise, however, in phospholipids content in all studied organs. That is to say a marked progress in the correction of lipid metabolism occurred. Also, administration of Cassia fistula induced a significant decrease in the high activities of serum GOT, GPT, alkaline and acid phosphatase and the values nearly returned the initial values. Total serum protein, albumin (A), globulin (G), A/G, free amino acids, uric acid and creatinine were also determined and their values were improved and attained nearly the normal values of the control group.

Male albino rats were fed on a mixture of cholesterol and cholic acid for 12 weeks to induce hypercholesterolemia, then Karkade was administered at 5 and 10% for 9 weeks to evaluate its hypocholesterolemic and hypolipemic effect. The experimental parameters include total lipids, cholesterol, triglycerides and phospholipids. Liver and kidney functions were also investigated in normal, hypo- and hypercholesterolemic rats administered Karkade. A remarkable progress (lowering effect) in the level of different lipid fractions was noticed in spite of the continued cholesterol and cholic acid loading during the treatment. However, blood phospholipids were increased after Karkade administration. Hypercholesterolemia has resulted in an effect on the activity of liver and kidney functions. Therefore, the measurement of serum enzyme activity has provided a useful tool for hepatic recovery. Although the administration of Karkade at 5 and 10% induced a significant decrease in the activity of serum GOT and serum GPT, alkaline and acid phosphatase as well as total serum protein, the values nearly returned to the initial levels after 9 weeks of Karkade administration.

A genetic study was carried out on phenotype and gene frequencies of the genetic markers in eight red cell enzymes: glyoxalase I (GLO1), glutamic pyruvate transaminase (GPT), phosphoglucomutase (PGM1), esterase D (ESD), adenylate kinase (AK1), 6-phosphogluconate dehydrogenase (6-PGD), adenosine deaminase (ADA), acid phosphatase (ACP1), in the Hungarian ethnic group living in Yugoslavia. The gene frequencies obtained were: GPT*1 = 0.542, PGM1*1 = 0.760, ESD*1 = 0.909, AK*1 = 0.971, PGD*A = 0.971, ADA*1 = 0.939, GLO1*1 = 0.417, ACP1*A = 0.329, ACP1*B = 0.591 and ACP1*C = 0.080. The distribution of these phenotype and gene frequencies was examined and compared with the phenotype and gene frequencies found for the Hungarian population living in Hungary and for other populations living in the northeast of Yugoslavia.

In Calotes versicolor, thyroidectomy did not alter the blood glucose level, lactate dehydrogenase (LDH liver and heart), acid phosphatase (Ac.Pase liver and kidney), and alkaline phosphatase (Alk.Pase liver and kidney) activities; significantly decreased the activities of glucose-6-phosphatase (G-6-Pase liver and kidney), glutamic oxaloacetic transaminase (GOT liver and heart), glutamic pyruvic transaminase (GPT liver), and urea concentration (liver and kidney); and increased liver cholesterol when compared to sham-operated controls. Administration of L-thyroxine (L-T4) or triiodo-L-thyronine (L-T3) to thyroidectomized lizards significantly stimulated the activities of G-6-Pase, Ac.Pase, GOT and GPT, concentration of glucose and urea, and decreased the cholesterol level. While the activities of all the enzymes studied and cholesterol level remain unchanged, glucose and urea levels decreased and increased, respectively, in thyroidectomized animals treated with actinomycin D. Chloramphenicol treatment did not affect any of the parameters studied. Simultaneous injections of actinomycin D or chloramphenicol with L-T4 prevented the hormone-stimulated activities of Ac.Pase, GOT, and GPT while the activities of LDH, G-6-Pase, Alk.Pase, glucose, urea, and cholesterol levels remain unchanged.

Dichlorvos was applied as spray at 1 and 2% concentrations daily for a period of 28 and 21 consecutive days, respectively to buffalo calves. Animals sprayed with 1% dichlorvos displayed mild to moderate clinical signs of toxicosis during the 4th week of exposure. The higher concentration (2%) produced clinical signs of poisoning after 12-16 applications, and was lethal to one of three animals. Daily spraying of dichlorvos at both concentrations inactivated erythrocyte cholinesterase (ChE) (15-21%), plasma ChE (17-20%) and serum carboxylesterase (5-10%) within 3 days. The extent of inhibition of esterases was increased with repeated treatment and maximal inhibition of erythrocyte ChE (80-89%), plasma ChE (81-91%) and serum carboxylesterase (33-54%) with 1 and 2% concentrations was observed on the 28th and 21st day after start of application, respectively. In surviving animals, blood esterases remained inactivated to the extent of 14-65% on the 14th day after the termination of treatment. Dichlorvos at both concentrations significantly (P less than 0.01) elevated the serum levels of aspartate aminotransferase, alanine aminotransferase, acid phosphatase and alkaline phosphatase. The activities of these enzymes in surviving animals recovered to control values within 14 days after the final application of dichlorvos.

Alkaline phosphatase (ALP, EC 3.1.3.1), acid phosphatase (ACP, EC 3.1.3.2), aspartate aminotransferase (ASAT, EC 2.6.1.1) and alanine aminotransferase (ALAT, EC 2.6.1.2) were measured in the mucosal homogenates of the duodenum, jejunum and caecum of full-fed (control), starved and refed White Rock Cockerels. Starvation caused a significant (p less than or equal to 0.05) increase in the activity of ACP in all three segments of the intestine. Subsequent re-feeding brought the activity back to the control level. In contrast ALP activity fell in the duodenum during starvation and was partially restored by refeeding. In the jejunum and caecum the ALP activity decreased during starvation and was fully restored by re-feeding only in the caecum. ASAT activity increased (p less than or equal to 0.05) during the entire period of starvation in all three segments. Re-feeding failed to decrease the enzyme activity within 48 hours. Starvation caused a reduction (p less than or equal to 0.05) in the activity of ALAT and re-feeding did not increase the activity in the duodenum and jejunum. The caecum showed no change in the activity during fasting.
