Studies on subactute toxicity and its recovery of pepleomycin sulfate (NK631) were carried out in both sexes of rats. NK 631 was administered intraperitoneally in dose levels of 0.3, 0.9, 2.7. 8.1 and 24.3 mg/kg/day for 30 days. After finishing administration of NK 631 for 30 days, 5 animals of each group were proceeded to recovery test for 35 days. During the course of the experiment, the body weight gains were suppressed in all dose levels except in 0.3 mg/kg group of male rats. The deaths were found in the animals treated with doses over 24.3 mg/kg during treatment period and in those over 2.7 mg/kg during recovery period. In biochemical and urinary analysis, the increases of serum GPT, BUN, Mg, Ca and urine glucose were moderately recognized in 8.1 mg/kg group. Additionally, in macroscopical and histopathological findings, bone damage was found in the animals treated with doses over 2.7 mg/kg during treatment and recovery periods. From these results, the maximum safety dose of NK 631 in subacute toxicity using rats were estimated to be about 0.3 mg/kg.

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.

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.

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.

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.

Liver enzymes alkaline phosphatase and transaminases (GPT & GOT) were studied in cases of protein-depleted rats. Alkaline phosphatase activities were determined with and without Mg addition to the incumedia, since it is the essential metal for this enzyme. The liver transaminases were also determined before and after pyridoxine injection, which is the coenzyme for this group. Both liver alkaline phosphatase and transaminases activities were increased on protein depletion. The study indicates that the increased activities of liver alkaline phosphatase in protein-depleted animals is suggestive of increased enzyme protein synthesis. On the contrary, high activities of liver transaminases are suggestive to be a result of some regulation mechanisms between the enzyme protein and its coenzyme.

The following blood indices were determined in the blood of 34 pregnant sows of the Large White breed under standard feeding conditions: haemoglobin, haematocrit, leucocytes, and--in the blood serum, --total protein, glucose, urea, bilirubin, cholesterol, enzyme activity (AP, GOT, GPT, GGTP) and mineral concentrations (Ca, P--inorg., Mg, Na, K, Fe, Cu, Zn, Mn). The blood was sampled in the first and third pregnancy at an average live weight of 165.12 and 197.36 kg, at an average age of 318 and 630 days and at an about the same average length of pregnancy in the time of both samplings (59 days). In younger, still growing gilts (first pregnancy) a significantly (P less than 0.05) lower content of total protein, magnesium, iron and copper was revealed, as compared with adult sows. The content of glucose, calcium, potassium and manganese in the blood serum of the gilts was significantly (P less than 0.05) higher than in sows in their third pregnancy. The adult sows showed a significantly (P less than 0.05) lowered activity of alkaline phosphatase and gamma-glutamyl transpeptidase, as distinct from gilts.
