In the serum of 40 male and 40 female rats the following parameters were determined: Sodium, potassium, creatinine, chloride, calcium, inorganic phosphorus, glucose, urea, protein, cholesterol, bilirubin, lipids, alanine amino-transferase, alkaline phosphatase and leucine arylamidase. The analyses were carried out in the same rats both after continuous feeding, and after a 24-hour fasting periods spaced at intervals of 3- to 4-weeks. The concentration of glucose and the activities of alanine aminotransferase and alkaline phosphatase were higher after feeding than after fasting, and in most cases these differences were statistically significant. The concentration of lipids tended towards increased values. The other parameters examined were slightly or not influenced by the time of the foregoing feeding.

The effect of selenite coadministration on the toxicity and antitumor activity of repeated treatment with high doses of cis-diamminedichloroplatinum (cis-DDP) was examined in mice. Sodium selenite was injected s.c. into separate abdominal sites of mice together with cis-DDP at a molar ratio of 1:3.5 (selenite to cis-DDP) on day 0. The same amount of selenite was given daily for 4 subsequent days (days 1-4). This fixed administration schedule was repeated weekly for a total of 7 weeks. Under the experimental conditions used, the lethal toxicity, renal toxicity [indicated by an increase in blood urea nitrogen (BUN) and plasma creatinine levels], hepatic toxicity (indicated by an increase in plasma GPT and GOT activity), and myelotoxicity (indicated by a decrease in the numbers of leukocytes and platelets) observed in mice given repeated doses of cis-DDP alone (15 or 25 mumol/kg, s.c.) were significantly depressed by the coadministration of sodium selenite. Treatment with cis-DDP alone (15, 20, or 25 mumol/kg, s.c.) resulted in some dose-dependent prolongation of the life span of mice transplanted either s.c. with colon adenocarcinoma 38 (colon 38) or i.p. with P388 leukemia (P388) but did not completely depress the tumor growth, and the animals died of either progressive disease or cis-DDP-induced toxicity. However, following the coadministration of 7.1 mumol/kg selenite with 25 mumol/kg cis-DDP, all of the mice transplanted either s.c. with colon 38 or i.p. with P388 survived for as long as 4 months after the end of the treatment and showed no evidence of malignancy. These results indicate that selenite coadministration enables the use of increasing doses of cis-DDP and, consequently, enhances the antitumor effect of cis-DDP by depressing its side effects.

1. Plasma calcium, magnesium, inorganic phosphorus, sodium and potassium concentrations, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and creatine kinase activities were determined in young and adult non-pregnant non-lactating, early and late non-lactating pregnant and early, mid- and late non-pregnant lactating Danish landrace goats in five herds. The purpose was to determine the influence of pregnancy and lactation on the levels of these parameters and the effect of age and parity on the changes. 2. Calcium, phosphorus, alanine aminotransferase, alkaline phosphatase and aspartate aminotransferase decreased in late gestation. Magnesium and creatine kinase decreased in early lactating goats but increased in subsequent lactation periods. Sodium and potassium fluctuated little during pregnancy and lactation. Calcium, magnesium and potassium profiles were inversely, while phosphorus was directly, proportional to parity. 3. There were significant differences in most ions and enzymes between goats of different herds (within the same physiological state). 4. The transferases and creatine kinase were higher in young goats than in old ones, while alkaline phosphatase was unpredictably high or low in individual goats. 5. Alterations in the level of plasma electrolytes and enzyme activities occur due to pregnancy and lactation and the degree depends on age and parity, influenced also by environment.

The influence of selenium on cis-diamminedichloroplatinum(II) (c-DDP) nephrotoxicity in mice and rats was assessed, using single doses of both compounds. Sodium selenite, 2 mg of selenium per kg, given 1 h before c-DDP, greatly reduced blood urea nitrogen and creatinine levels and morphological kidney damage in both BALB/c mice and Wistar rats, while administration 1 h after c-DDP did not. Liver toxicity of selenium was evaluated by measuring serum glutamic pyruvate transaminase and serum glutamic oxalate transaminase and by routine histology. No liver damage was observed in animals treated with sodium selenite, 2 mg of selenium per kg, and physiological saline or c-DDP. Pretreatment with sodium selenite did not reduce the antitumor activity of c-DDP against MPC 11 plasmacytoma or Prima breast tumor in BALB/c mice. The present results indicate that sodium selenite may provide protection against c-DDP nephrotoxicity, when it is given before c-DDP. Moreover, selenium has an antineoplastic activity against several tumors. The combination of these qualities may open new perspectives in cancer chemotherapy.

Sodium ferulate (SF) is one of the effective components of Angelica sinensis Diels. Pretreatment with SF (100 mg.kg-1 ig, qd x 10 d) inhibited the activity of serum alanine aminotransferase, prevented the depletion of liver glycogen and glutathione, increased the liver homogenate and microsomal glutathione S-transferase activities, and reduced the malondialdehyde content, the membrane fluidity of liver microsome and the mitochondria in paracetamol (130 mg.kg-1, ip)-induced liver toxicity in mice. These results demonstrated the hepato-protective action of SF in mice.

The values of assayed various chemical constituents in serum were varied on fasting therapy. The correlationship of the change among such constituents was investigated by drowning the dendrogram using fuzzy similarity relations. Normal and severe obese subjects were respectively selected from the fasting patients at Hyogo prefectural KENKO DOJO, and in contrast non-fasting healthy people were also selected. Fasting was practice under the conditions of 300 Kcal per day for 7 days, and then refeeding was enforced for 7 days after fasting. 21 Items of biochemical tests were used for this analysis, and dendrogram was drown by Otake's method. On the dendrogram of reference, the significant correlations between AST and ALT, Total Protein and Cholinesterase, Sodium and Potassium were found. The dendrogram of fasting period of normal group showed the simple patterns, and unique correlations were drawn on the dendrogram of refeeding period of normal group. The dendrogram of severe obese group of refeeding period showed more simple patterns than fasting period.

Preliminary short-term toxicity studies of sucrose acetate isobutyrate (SAIB) in the dog demonstrated that addition of this additive to the diet was associated with an increase in liver size and elevated serum alkaline phosphatase activity with no evidence of pathological change by light microscopy. To determine the basis for these changes, a 12-week oral toxicity study of SAIB was conducted in the dog and a similar study was performed in the rat. SAIB was fed in the diet to groups of six beagle dogs of each sex at 0, 0.5, 1.0, 2.0 and 4.0%. SAIB was also fed to groups of 40 Sprague-Dawley rats of each sex at levels of 0, 2.5, 5.0 and 10.0%. In the rat study, in addition to routine toxicology parameters, hepatic microsomal enzyme induction was determined using a zoxazolamine hypnotic test, urinary ascorbic acid excretion and determination of hepatic carboxylesterase activity. Sodium phenobarbital was fed to groups of 20 rats of each sex at a dose of 100 mg/kg body weight/day by gavage as a positive control for hepatic microsomal enzyme induction. In the dog study, routine toxicological tests were supplemented by tests for bromsulfophthalein (BSP) retention, histochemical staining of liver sections for glycogen, phosphorylase, succinate dehydrogenase, and acid and alkaline phosphatases. Levels of liver lipid, protein, glycogen and carboxylesterase activity were also determined. Electron microscopic examinations were made on liver sections from the dog study at the end of the 12-week SAIB feeding period and after a 2-week withdrawal period. Administration of SAIB to rats did not reveal evidence of any effect on hepatobiliary function, and there was no indication of microsomal enzyme induction. Body weight gain of male rats fed SAIB was decreased, probably as the result of decreased palatability of the diet; SAIB did not affect body weight gain in females. The changes observed in the dogs fed SAIB included increased serum alkaline phosphatase activity with no change in serum alanine aminotransferase, aspartate aminotransferase or lactic dehydrogenase activity and no change in serum electrolyte, serum protein, glucose or bilirubin levels. No haematological changes were observed. BSP retention was observed at all SAIB dose levels. There were no SAIB-related pathological changes in any organ when examined by light microscopy. Examination by electron microscope revealed dilatation of bile canaliculi and an increase in smooth endoplasmic reticulum compared with controls. Histochemical studies also indicated increased enzyme activity of the bile canaliculi. The electron-microscope-revealed changes were completely reversed during a 2-week treatment withdrawal period. The dog study did not establish a no-effect level for changes in hepatobiliary function induced by feeding SAIB.

This randomized, single blind clinical trial was performed to compare the efficacy and toxicity of BP88 Sodium Stibogluconate (SS) to Glucantime(R) (N-methyl-glucamine), (GL). Sixty-three patients were randomly assigned to one of two groups: 32 patients were treated with GL and 3l patients were treated with SS. Both groups received 15mg Sb+5/kg/day for 20 days. Toxicity was evaluated through EKG, urea, creatinine, AST, ALT, alkaline phosphatase, amylase, and lipase, assessed before treatment, on day 10 and day 20 of treatment and 90 days after treatment. In the group treated with GL, 81% (26/32) of patients were cured compared to 77% (24/31) in the SS group. Five (16%) patients relapsed in the GL group compared to 6 (19%) in the SS group. One patient in each group did not respond to treatment. AST, ALT, amylase, and lipase were more elevated in the SS group (p < 0.05). In conclusion, the efficacy of both treatments was similar although there was more toxicity in the ES group.

In each of two experiments, rats were pre-exposed to two flavoured solutions, saline-lemon and sucrose-lemon. For group ALT, trials with one solution alternated with trials with the other. Group BLK received all trials with one solution in a block, before any trials with the other. An associative theory suggests that the alternating, but not the blocked, schedule would establish an inhibitory association between sucrose and saline. To provide a retardation test of this inhibition, some animals in each group were then given a single pairing of saline and sucrose, experienced sodium depletion, and were finally tested for their consumption of sucrose. Sodium depletion increased consumption of sucrose more in group BLK than in group ALT. In groups given no saline-sucrose pairing, sodium depletion had only a small effect on sucrose consumption, which was the same in both groups. After multiple pairings of saline and sucrose, sodium depletion had an equally large effect on sucrose consumption in both ALT and BLK groups. These results imply that alternating pre-exposure to two compound solutions does establish an inhibitory association between their unique elements, and thus provide support for an associative theory of perceptual learning.
