During the first cycle of treatment the influence of four forms of sequence therapy with mestranol and ethinyl estradiol as estrogen and the two gestagens chlormadinone acetate and norethisteron acetate in women at fertile age was examined for the aminotransferases (GOT and GPT), the activity of alkaline phosphatase and alpha-amylase, for the cholesterol, total bilirubin and total protein content of the serum and for the half-life period of indocyanine green. Under the application of mestranol/chlormadinon acetate an estrogen-induced increase of the activity of the alanine aminotransferase (GPT) from 6.38 units/l to 12.14 units/l may be established, after addition of the gestagen chlormadinon acetate a decrease to 5.34 units/l was to be established. Under the sequence therapy with mestranol/norethisteron acetate only an increase of the alpha1-globulin proportion was to be ascertained. All the other changes of the tested parameters including the half-life period of indocyanine green were not essential.

Emergency endoscopy was performed on two patients subsequently found to be hepatitis B surface antigen carriers. Before their carrier state was determined, nine other patients underwent endoscopy using the same instruments, which had been routinely cleaned between procedures. These patients were all notified within five days of the incident, given standard gamma globulin, and prospectively followed for the development of hepatitis. After one of the endoscopes was gas sterilized, the next three patients undergoing endoscopy were also followed. One of the hepatitis B surface antigen carriers was positive for antibody to e antigen; the other carrier had neither e antigen nor antibody. None of these individuals developed signs or symptoms of hepatitis, abnormal serum glutamic pyruvate transaminase elevations, or serologic evidence of hepatitis B exposure. From these data, and other recorded experiences, it appears that routine cleansing of endoscopy equipment is sufficient in preventing the transmission of hepatitis B.

Four group systems of serum proteins (Hp, Gc, Gm, Km) and five group systems of erythrocyte enzymes (AP, PGM1, GPT, AK, EsD) were determined in 63 patients with malignant lymphoma. Statistical analysis of the distribution of the above mentioned systems in patients and Polish population samples did not reveal any significant differences, which points to the lack of any correlation between the disease and the group systems under examination.

The effects of two sequential therapies using mestranol as an estrogen and chlormadinone acetate and norethisterone acetate, respectively, as a gestagen on the aminotransferase (GOT and GPT), alkaline phosphatase and alpha-amylase activities, the cholesterol, total bilirubin and total protein contents and the indocyanine green (Ujoviridin, VEB Chemiekombinat Bitterfeld) half-life were studied in two groups, each comprising 12 women of fertile age. The serum protein was separated by paper electrophoresis and both the thymol turbidity and zinc sulphate tests were performed during the first treatment cycle. An estrogen-induced rise in alanine aminotransferase (GPT) activity from 6.31 U/liter to 12.14 U/liter was observed during application of the mestranol/chlormadinone acetate therapy. The value dropped to 5.34 U/liter when chlormadinone acetate was administered as a gestagen in addition to the estrogen. No significant changes were noted in the other biochemical parameters. Sequential therapy involving application of mestranol and norethisterone acetate produced only statistically secured rises in the alpha 1-globulin content and the GPT activity. All other changes in the different parameters remained within the normal range and were statistically insignificant.

2 different sequence preparations were administered to 2 groups of 20 women, 17-41 years of age. Several biochemical parameters, including Ujoviridin ICG tests, were taken 2 days before o.c. use, on the day that the gestagen component was begun, and on the final day of sequential preparation use. In the group takine .08 mg mestranol and 2 mg chlormadinon acetate, a significant increase of the GPT values was observed during the first phase of the sequential preparation. After the gestagen component was introduced, the GPT fell significantly to below initial levels. In the group taking .08 mg mestranol and 1 mg norethisterone acetate, significant increases in the chi-one-globulin levels and the GPT were observed during the first phase of treatment. All other values remained within normal levels, and no significant difference was found between the results obtained from the 2 preparations.

Proteolytic aspartate and alanine aminotransferase, beta-D-galactosidase, N-acetyl-beta-D-glucosaminidase activities, contents of phosphocreatine, AMP + IMP, ADP, ATP were studied in the rat musculi gastrocnemius after denervation and blockade of axoplasmic flow, the latter being caused by 0.05 M colchicin solution applied to the sciatic nerve. Two weeks after denervation and the axoflow disturbance all the indices (except the N-acetyl-beta-D-glucoseaminidase activity) showed uniform changes. A month following the colchicin blockade the phosphocreatine and adenylates contents became normal. A conclusion is made on significance of the axoplasmic flow as a factor performing the trophic function of the nervous system.

A study of the various biological parameters of the blood in the genetically obese Zucker rat, the nonobese Zucker rat, and the Wistar rat has revealed great similarity between the two latter types of animals. On the other hand, in genetically obese Zucker rats as compared with the nonobese ones, (1) the blood mass per unit of weight was lower; (2) the level of nitrogenous degradation compounds was the same; (3) the lipase activity was lower; (4) the levels of substances for which liver plays a crucial role--all lipid and protein fractions, glucose, and the enzyme GPT--were higher; (5) the levels of Ca, Zn, Fe, Cu and Pi were high; (6) the blood and bone-marrow cells were unremarkable.

Chronic ammonia toxicity in experimental mice was induced by exposing them for 2 and 5 days to 5 % (v/v) ammonia solution. The enzymes concerned with glutamate metabolism (aspartate-, alanine- and tyrosine aminotransferases, glutamate dehydrogenase and glutamine synthetase) and (Na+ + K+)-ATPase were estimated in the three regions of brain (cerebellum, cerebral cortex and brain stem) and in liver. Glutamate, aspartate, alanine, glutamine and GABA, RNA and protein were also estimated in the three regions of brain and liver. A significant rise in the activity of (Na+ + K+)-ATPase in all the three regions of brain along with a fall in the activity of alanine aminotransferase was noticed. Changes in the activities of other enzymes were also observed. A significant increase in alanine and a decrease in glutamic acid was observed while no change was observed in the content of other amino acids belonging to the glutamate family. As a result of this, changes in the ratios of glutamate/glutamine and glutamate + aspartate/GABA was observed. The results indicated that the brain was in a state of more depression and less of excitation. Under these conditions the liver tissue was showing a profound rise in the activity of the enzymes of glutamate metabolism. The results are further discussed.

The influence of acute poisoning with Dursban (O.P.I.) and D.D.T. (O.cl.I.) on serum enzymes and histopathological examination of the liver, kidney and testes was investigated in albino rats. Two repeated i.p. injections of Dursban in a dose of half the LD 50 resulted in a significant increase in serum GOT, GPT and alkaline phosphatase activity and a decrease of cholinesterase. In case of DDT, two doses of 150 mg/kg orally resulted in a significant increase in the activity of serum GPT only, while three doses increased serum GOT and GPT. No significant change was observed in serum alkaline phosphatase and cholinesterase activity. Regarding the pathological examination it was found that in animals treated with Dursban there was liver necrosis of mid-zonal type and fatty change at the periphery. In case of DDT the liver cells lost their radial arrangements and showed fatty change. There was cellular infiltration in the centre, mostly mononucleolar cells. In both insecticides there was necrosis of some of the seminiferous tubules of the testes and cloudy swelling of the convoluted tubules of the kidney. Histochemical study of the liver in animals treated with Dursban showed that glycogen was deposited at one side of the cell. However, there was depletion of glycogen around the central vein. In liver treated with DDT there were large globules of fat inside the liver cells, indicating increased fat content compared to control liver, where there were tiny minute droplets of fat.

1. The activities of lysozyme, acid and alkaline phosphatases, beta-glucuronidase, amylase, lipase, glutamate-oxalacetate transaminase, and glutamate-pyruvate transaminase in the whole hemolymph and 4000 g pellets and supernatants of Mya arenaria were determined. 2. All of these enzymes, except for amylase, occurred in whole hemolymph as well as in the 4000 g pellet and supernatant. 3. Based on earlier observations, these enzymes are believed to be of cellular origin within hemolymph cells. 4. In the case of amylase, it only occurred in the whole hemolymph and/or serum and is believed to have originated from the crystalline style.
