The crude protein levels as well as the activities of various enzymes were studied in certain tissues of fetuses (80th through 114th days of development), piglets of different age groups, and pigs for slaughter. In most of the tissues tested the postnatal activities of Na-K-ATPase were beyond those recorded from fetuses. The highest GOT activities were recorded from the liver, myocardium, and kidneys. Activities were found to rise sizeably in some tissues after birth. The activity of GPT, too, exhibited age-dependent variations. The activity of leucine-aminopeptidase increased strongly after birth in liver and kidneys. Acid phosphatase activity was less markedly influenced by development phases. Those enzymes which are involved in the formation of fructose and glucose (aldolreductase, glucuronate-reductase, and sorbite-dehydrogenase) had their highest activities, all age-dependent, in liver and kidneys.

The method for the determination of enzymic activity in turbid, lipaemic sera, which involves clearing by polyanion precipitation with heparin and magnesium chloride, was critically reviewed. In the diagnosis of diseases of the liver and pancreas, which are frequently associated with hyperlipoproteinaemia, only residual enzyme activities are measured in the cleared serum after polyanion treatment. In the measurement of glutamate dehydrogenase and in the Phadebas test for alpha-amylase, the enzymes are inactivated by treatment with heparin and magnesium chloride. On the other hand, as a result of polyanion precipitation gamma-glutamyl transferase is transferred, together with lipoproteins and chylomicrons, to the lipid-rich supernatant. Acid phosphatase also exhibits only residual activity in cleared serum. The activity of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, leucine arylamidase, cholinesterase, creatine kinase, lactate dehydrogenase, and alpha-hydroxybutyrate dehydrogenase, and the activity of alpha-amylase in the Merckotest are not affected by polyanion treatment of the serum.

The effect of sub-lethal doses of Malathion and Methyl-parathion was studied on the rat liver enzymes. Intravenous administration of both insecticides at weekly interval for four weeks resulted in increase in heart and spleen weight. Short term (24 hr.) and long term (4 weeks) treatment with insecticides resulted in increased specific activities of liver enzymes, Acid phosphatase, Alkaline phosphatase, Glutamate dehydrogenase, Glutamate oxaloacetate transaminase and Glutamate pyruvate transaminase. The increase in enzyme activity was not as profound when the insecticide administration was spread over 4 weeks. Malathion had greater effect than Methyl-parathion on the biochemical parameters studied.

The effect of sub-lethal doses of Malathion and Methyl-Parathion was studied on the rat liver enzymes. Intravenous administration of both insecticides at weekly interval for four weeks resulted in increase in weight of various tissues, i.e., heart and spleen. Short term (24 hr) and long term (4 weeks) treatment with insecticides resulted in increased specific activities of liver enzymes, Acid phosphatase, Alkaline phosphatase, Glutamate dehydrogenase, Glutamate oxaloacetate transaminase and Glutamate pyruvate transaminase. The increase in enzyme activity was not as profound when the insecticide administration was spread over 4 weeks. Malathion had greater effect than Methyl-parathion on the biochemical parameters studied.

Five different enzyme activities were estimated in ejaculates obtained from 96 men visiting our infertility clinic. Sperm count showed a significant positive correlation with aspartate-aminotransferase (GOT) and alanine-aminotransferase (GPT). Acid phosphatase was positively correlated with gamma-glutamyl transpeptidase (GGTP) and citrate and negatively with fructose. GGTP showed similar relationships with citrate and fructose. For beta-glucuronidase a low positive correlation with GGTP and GOT was detected. The enzyme activities of 27 ejaculates with a high viscosity were not significantly different from the activities of ejaculates with normal liquefaction. The conclusion is reached that insufficient prostatic enzyme secretion is not the cause of abnormal liquefaction in these patients.

Serological and biochemical studies were done at the National Taiwan University Hospital, on 243 patients with biopsy-proved anaplastic nasopharyngeal carcinoma (NPC) in various clinical conditions. The remarkable elevation of both IgG and IgA antibody titers against EB virus was specific for NPC patients. The seropositive rates ranged from 75% to 100% in various stages of NPC patients. Serum IgG and IgA levels were also increased moderately and nonspecifically in stages II-IV and recurrent patients. Peripheral white blood cell count was also slightly increased in these patients. Peripheral lymphocyte counts were slightly decreased in patients with neck recurrence or distant metastasis. Serum IgM, C3, C4 and Acid phosphatase levels were within normal range in all the patients. Serum GOT, GPT, alkaline phosphatase, and lactate dehydrogenase were elevated in some of patients with distant metastasis and in most of those with liver metastasis. Mucoprotein was elevated in about 10% of stage II-IV patients but in about 50% of patients with recurrent neck metastasis or distant metastasis. in conclusion, serological and biochemical examinations are important in the diagnosis of late stages and recurrence or metastasis of NPC.

In rabbits, the right hind limb was immobilized by means of plaster cast for 1, 2, 4 or 6 weeks and the activities of some metabolic enzymes: GOT, GPT, LDH, aldolase and acid phosphatase (in part of lysosomal origin), were examined in the slow m. soleus, and in the fast m. gastrocnemius. The former muscle is known to have mainly an oxidative, while the latter mainly a glycolytic type of metabolism. The activities of enzymes highly involved in the metabolism of the muscle diminished for a certain time during atrophy, then a relative rise occurred. Acid phosphatase activity likewise decreased after an initial relative increase. Reduction of enzymatic activities is explained by the activation of proteolytic enzymes, on the basis of measurements performed in these experiments and of results published by others. The decrease of enzymatic activity was more marked in the muscle which in normal state exhibits higher activity than in the other type of muscle studied. Thus, in the gastrocnemius a high rate of degradation of glycolytic enzymes was observed, while in the soleus degradation of oxidative enzymes prevailed. This phenomenon leads to the dedifferentiation of the muscle cell during immobilization.

Hyperprolinemia type II (HPII) is an autosomal recessive disorder caused by the severe deficiency of enzyme delta1-pyrroline-5-carboxylic acid dehydrogenase leading to tissue accumulation of proline. Chronic administration of Pro led to significant reduction of cytosolic ALT activity of olfactory lobes (50.57%), cerebrum (40%) and medulla oblongata (13.71%) only. Whereas mitochondrial ALT activity was reduced significantly in, all brain regions such as olfactory lobes (73.23%), cerebrum (70.26%), cerebellum (65.39%) and medulla oblongata (65.18%). The effect of chronic Pro administration on cytosolic AST activity was also determined. The cytosolic AST activity from olfactory lobes, cerebrum and medulla oblongata reduced by 75.71, 67.53 and 76.13%, respectively while cytosolic AST activity from cerebellum increased by 28.05%. The mitochondrial AST activity lowered in olfactory lobes (by 72.45%), cerebrum (by 78%), cerebellum (by 49.56%) and medulla oblongata (by 69.30%). In vitro studies also showed increase in brain tissue proline and decrease in glutamate levels. In vitro studies indicated that proline has direct inhibitory effect on these enzymes and glutamate levels in brain tissue showed positive correlation with AST and ALT activities. Acid phosphatase (ACP) activity reduced significantly in olfactory lobes (40.33%) and cerebrum (20.82%) whereas it elevated in cerebellum (97.32%) and medulla oblongata (76.33%). The histological studies showed degenerative changes in brain. Following proline treatment, the animals became sluggish and showed low responses to tail pricks and lifting by tails and showed impaired balancing. These observations indicate influence of proline on AST, ALT and ACP activities of different brain regions leading to lesser synthesis of glutamate thereby causing neurological dysfunctions.

Balarishta and Dhanvantara gutika are ayurvedic medicines prescribed in different diseases including rheumatism. These medicines were screened for anti-inflammatory activity against cotton pellet induced granuloma in albino rats. There was significant reduction in cotton pellet weight by both the tested drugs. Dhanvantara gutika significantly reduced the ascorbic acid in adrenal. Acid phosphatase, GPT and GOT activities were significantly reduced by Balarishta, Dhanvantara gutika and phenyl butazone in liver. In the serum acid phosphatase activity was significantly reduced by both the tested drugs and phenul butazone while GPT activity was lowered by Balarishta alone and GOT activity was reduced by Balarishta and Dhanvantara gutika. Phenyl butazgone reduced the activity of GPT.

The serum and hepatic enzymes of rats were studied after exposed to country made liquor (CML) along with two chelating agents (glutathione and Selenium). There was a significant increase in several serum enzyme levels (viz., aspartate transaminase, alanine transaminase, alkaline phosphatase, sorbitol dehydrogenase, glutamate dehydrogenase, bilirubin) and decrease in various hepatic enzymes (Succinic dehydrogenase, Glucose 6-phosphatase, 5'Nucleotiease, Acid phosphatase, Acid ribonuclease, Cytochrome P-450) due to repeated administration of CML (2ml/100g of body weight). Results of this study revealed that the GSH and Se could give a significant protective action in serum and hepatic enzymes of CML exposed rats.
