A detailed investigation on the anti-inflammatory activity of the butanol fraction of a methanol extract (BMEL) of the defatted leaves of Paederia foetida was undertaken to find the pharmacological basis for the ethnomedical use of the plant. This fraction produced a significant inhibition of granulation tissue formation in cotton-pellet implanted rats. It decreased liver aspartate transaminase activity without affecting serum aspartate transaminase activity. It did not, however, affect adrenal weight and ascorbic acid content significantly, thus ruling out a stimulation of the adrenal-pituitary axis. BMEL antagonised hyposaline-induced haemolysis of human red blood cells and an elevation of rat serum acid phosphatase activity, indicating the presence of a membrane stabilising activity. It also inhibited the elevation of serum orosomucoid levels in rats, suggesting the possibility of the presence of disease-modifying antirheumatic activity. The results indicate that there is some rationale behind the ethnomedical use of the plant for treating inflammatory disorders.

Despite the relatively ready availability of thyroid cyst fluid specimens, little has been published on their biochemical composition. We measured the concentrations of 18 analytes in thyroid cyst fluid specimens from benign (n = 17) and malignant (n = 3) lesions and in homogenates of normal thyroid tissue (n = 5). The concentrations of an additional five analytes were measured in selected cyst fluid specimens only. Compared with normal human serum specimens, we found that in thyroid cyst fluid specimens the activities of acid phosphatase, aspartate aminotransferase, amylase, and lactate dehydrogenase, and the concentrations of iron and total bilirubin were highly increased. The concentration of glucose was low. The gross appearance of the fluids and the presence of certain analytes were consistent with a hemorrhagic origin of most of the benign and malignant cyst fluid specimens. Other biochemical markers, however, indicated colloidlike features and/or an admixture of thyroid tissue components to the cyst fluid. Although we have limited data for cyst fluid specimens from malignant thyroid lesions, we found no evidence that the results of any of the common biochemical tests would distinguish benign from malignant lesions.

Cyclophosphamide, and antineoplastic drug, and vitamin E, the common antioxidant present in the diet, were administered in separate dosages and in combination to animals (rats) with fibrosarcoma, metastatic tumor of the connective tissues, induced. The anticancer drug (20 mg/kg body weight) and the vitamin-E (400 mg/kg body weight) was administered for a period of 28 days from the day of tumor transplantation. The individual and the combined effects of these two substances were investigated by checking the growth of the tumor. Tumor markers like lactate dehydrogenase (LDH), serum glutamate pyruvate transminase (SGPT), serum glutamate oxaloacetate transaminase (SGOT), acid phosphatase, and alkaline phosphatase were analyzed for the changes in their concentration in serum, liver, and kidney to assess the success of the therapy. The increased level of the enzymes in the fibrosarcoma-suffering rats (GPII) was reduced by cyclophosphamide treatment (GP III) and vitamin E administration (GP IV). Among the treated groups, the combination therapy (GP V) showed greater efficacy in the treatment of fibrosarcoma than did individual administration, as there was more reduction in the levels of enzymes in Group V than those in to Groups III and IV. The enzyme levels were brought to near the normal level.

The aim of the investigation was to determine the effect of cryodestruction of the healthy prostate on general condition of dogs. The research was performed on 18 dogs divided into two groups: control and experimental. In the dogs from the experimental group after the laparotomy procedure the prostate was frozen in the repeated cycle using the flat cryoapplicator. The observations were carried out for 6 months. General condition of dogs was controlled, blood was examined and urine analysed. The performed determinations included the activity of alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, acid phosphatase and prostatic isoenzyme of acid phosphatase. It has been observed that the cryodestruction procedures of the prostatic gland are well tolerated by dogs. During 3 weeks after the surgery the number of leucocytes in blood increased. An increased drop of the blood cells was observed for 2 weeks after the procedure. Characteristic behaviour was observed in case of the prostatic isoenzyme of acid phosphatase. Immediately after the procedure the increased activity of that enzyme was observed and 24h later its decrease which remained for about 2 weeks. Then the isoenzyme activity increased again and that increase lasted for the period of 2 months.

Milt of brown, rainbow and brook trout was cryopreserved. Activity of aspartate aminotransferase (AspAT) and acid phosphatase was assayed both in supernatants and in spermatozoa obtained from thawed sperm samples; additionally, post-thaw motility was evaluated. Enzyme activities differed according to fish species and were strongly affected by the type of cryoprotectant used. The activity in supernatants was usually higher than that in spermatozoa because of protein leakage from injured cells. AspAT activity in cryopreserved spermatozoa correlated positively with fertilization success in all three species. There was a negative correlation between activity of extracellular (supernatant) AspAT and fertilization rates in variants with dimethyl sulfoxide and dimethylacetamide-based extenders. The motility of thawed sperm, determined microscopically, provided some information on the cryopreservation efficiency of trout milt.

Effect of fenvalerate on cell architecture, tissue biochemical parameters and its residual concentration was studied in broiler chicks following dermal application at 0.1 and 1% in ethanol once daily for 31 days. It did neither produce loss of body weight nor clinical signs of toxicity. Kidney contained maximal residue followed by heart, fat, liver and brain after 0.1%; and fat contained maximal residue followed by kidney, heart, liver and brain after 1% application. Fenvalerate (0.1%) increased the aspartate aminotransferase (AST) (except brain), alanine aminotransferase (ALT), alkaline phosphatase (AP), acid phosphatase (AcP) (only brain) activities, glycogen level (only liver) in liver, kidney, heart and brain tissues; and 1% increased the AST (except brain), ALT, AcP (except liver and kidney), AP (only heart), glycogen (only liver) and decreased AP (except heart), AcP (only kidney), cholesterol (except liver and heart), and acetylcholinesterase (AChE) (liver and brain) of liver, kidney, heart and brain tissue homogenates respectively. Histopathological examination in general showed aggregation of mononuclear cells in liver, around the kidney tubules and cardiac muscle fibre. In addition, fibrosis in the periportal area of liver, proliferation of ureter and tubular degeneration, and congestion of endocardial vessels were also observed. The intensity of cellular changes was more marked after 1% dermal application.

Tumour markers correlate strongly with prognosis based on tumour burden and surgical resectability. If chemotherapy is extremely effective in certain stage of the disease, the sensitive marker may be of great use in monitoring disease response and drug treatment. Hence, this study was launched to evaluate the changes in tumour marker enzymes like lactate dehydrogenase (LDH), glutamate oxaloacetate transaminase (SGOT), glutamate pyruvate transaminase (SGPT), alkaline phosphatase, and acid phosphatase in before and after 3 and 6 months tamoxifen treated breast cancer patients. In addition, the changes in serum glycoproteins viz., hexose, hexosamine, and sialic acid and lysosomal enzymes such as N-acetyl-beta-D-glucosaminidase, beta-D-galactosidase, and beta-D-glucuronidase were analysed in these patients. These values were compared with their age matched healthy control subjects. At 6 months evaluation, the tamoxifen treated postmenopausal breast cancer women showed a statistically significant decreased (p < 0.001, 0.05 respectively) levels of LDH, SGOT, SGPT, alkaline and acid phosphatases than their baseline values. Similarly, the levels of hexose, hexosamine, and sialic acid and N-acetyl-beta-D-glucosaminidase, beta-D-galactosidase, and beta-D-glucuronidase were decreased significantly (p < 0.001) in tamoxifen received postmenopausal women. The result of this study suggested that tamoxifen potentially retard the metastasis of breast cancer as well as the bone demineralisation in postmenopausal breast cancer women. Thus, tamoxifen may also have its antitumour activity through its beneficial effects on tumour marker enzymes and serum proteins in breast cancer women.

Cisplatin caused differential toxic effects on blood glucose and plasma urea, uric acid and creatinine levels. Cisplatin also showed an inhibitory effect on kidney marker enzymes like alkaline phosphatase, acid phosphatase, aspartate aminotransferase and alanine aminotransferase. However, administration of glutathione ester modulates the toxic side effect of cisplatin observed in kidney enzymes, and in blood parameters. It seems that glutathione ester plays an important role in protecting against the cisplatin induced nephrotoxicity by inhibiting the accumulation of platinum in kidneys.

Dry powder and different extracts of Agave lophantha were tested against Biomphalaria alexandrina. The results showed that the butanol extract has high molluscicidal activity. The activity of the dry powder has been found to be stable under the effect of some simulated field conditions. Also the toxicological effect of the plant on mice was tested through determination of certain parameters such as total protein, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and acid phosphatase enzymes as well as histopathological study on liver and kidney.

Natural products from plants are rich sources used for treating a number of diseases. Many of the pharmacological principles of the currently used anticancer agents have been initially isolated from plants. Most of the herbal drugs are a mixture of a number of plant ingredients. Their cumulative effect increases the efficacy of the drug in curing the diseases. Muthu Marunthu is a herbal formulation comprising of eight various plant ingredients, and has been claimed to possess antitumor effect. Therefore, attention has been focused on studying the various plant ingredients in the drug as a whole for its antitumor effects. It was observed that the growth rate in rats was normal and there was no change in blood parameters such as glucose, urea, proteins, cholesterol and also in the activities of pathophysiological enzymes such as lactate dehydrogenase (LDH), glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT), alkaline and acid phosphatase after Muthu Marunthu administration. The tumor weight was found to be reduced in methylcholanthrene induced fibrosarcoma rats after Muthu Marunthu treatment. Elevated levels of glycocomponents of glycoproteins such as hexose, hexosamine, sialic acid and fucose in plasma of fibrosarcoma rats decreased significantly after Muthu Marunthu treatment. The DNA and RNA levels of liver and kidney, which were increased in fibrosarcoma rats, returned to near normal levels after Muthu Marunthu treatment. The vitamins such as A, C and E in plasma were decreased in fibrosarcoma rats but increased significantly after Muthu Marunthu treatment. The altered levels of copper, zinc and selenium in plasma have also been corrected after Muthu Marunthu treatment. These observations clearly suggested the antitumor potency of Muthu Marunthu in experimentally induced fibrosarcoma in rats.
