The histrochemistry of the adrenal glands was studied in four adult male marmosets (two Callithrix jacchus and two Callithrix penicillata). It was impossible to demonstrate any reactivity to UDPG-GT, ADH, alanyl aminopeptidase, leucine aminopeptidase, xilitol (NAD-dependent) dehydrogenase, beta-glucuronidase and aryl-sulfatase in these glands. Total phosphorylase was found in scattered cells of the glomerulosa and adjacent outer fasciculata of one C. penicillata. The dehydrogenases (LDH, G-6-PDH,6-PGDH, NADPH2-TR,ICDH,SDH,NADH2-TR, alpha-GPDH, beta-OHBDH) as well as the hydrolases (except alkaline phosphatase, ATPase, and acetylcholinesterase) showed a stonger reactivity in the cortical part. Some hydrolases (naphthol acetate esterase, acid phosphatase) and cytochrome oxidase were less reactive in the zona glomerulosa, where the dehydrogenases were more abundant. The outer fasciculata and the reticularis also showed a strong dehydrogenase reactivity.

The activities of GOT, GPT, LDH, gamma-glutamyltranspeptidase (gamma-GTP), alkaline phosphatase (AP), glutamate dehydrogenase (GLDH) and the concentrations of bilirubin in blood plasma after a single intraruminal application of aflatoxins were studied in four dairy cows. The maximum changes in the activities of the enzymes and the maximum bilirubin concentration in plasma were obtained in the first two to three days following the application of aflatoxins. The statistically significant increase of GOT activity, compared with activity before the application of aflatoxins, persisted until the 23rd day; in the case of LDH and GLDH the increase persisted until the 38th day from the application of aflatoxins. The activities of gamma-GTP and AP were slightly higher even on the 50th day. The increased concentration of bilirubin in plasma lasted until the 23rd day from aflatoxin application. The increased activities of enzymes testify to an impaired function of the liver, which is also proved by the specific enzymes GLDH, gamma-GTP, by increased bilirubin levels, and by histological changes known from literature. The evaluation of enzymatic activities and bilirubin concentration in plasma can make a valuable contribution to correct diagnosis of aflatoxicoses in cattle.

The present study reports of three kinds of experiments of unaffected primary rejection of xenogenous kidney transplanats in the close-related fox-dog species system. The issue is whether there is a relation between the amount of grafted parenchyma and the immune induced potency, that is whether the course of rejection of transplanted single kidneys (group I a) differs from the course after en-bloc transplantation of both kidneys (group I b). In group II alterations of blood chemism and behavior of humoral antibodies are followed in dogs to which a fox kidney was transplanted, while keeping their own functioning kidneys. This experiment is to give information whether the uremic syndrome influences the development of humoral immunity, and what changes of blood chemism may primarily be related to destruction of the graft, under the condition of absent uremia. Untreated graft recipients survived for 5,4 +/- 0,49 days (n = 5) when single kidneys were transplanted (group I a), and 5,2 +/- 0,75 days (n = 5) when both kidneys were grafted en-bloc (group I b). As to the rejecting reactions, both groups are almost equal: the increasing functional failure causes a fast increase of creatinine and urea nitrogen; alkaline phosphatase and LDH show distinct alterations, related to the progress of the graft's destruction. Decrease of albumin level and loss of cholinesterase activity indicate an impaired hepatic function as reaction to uremic intoxication. Gamma-globulins and leucocytes show alterations that can be related to non-specific inflammatory reactions. The immunologically specific initial lymphopenia suggests that after revascularization these cells migrate to the graft, and later react with antigenic structures of vascular endothelium and still later with those of the organ cells. Cytotoxic antibodies appear on the 4th postoperative day in increasing amount. Post mortem histologic examination shows round cell infiltrates in the vastly necrotic renal parenchyma. When the recipient's kidneys are kept in situ and a fox kidney is transplanted (group II) uremia is avoided and the animals survive. During the 30-days period of observation, that is longer than the term of rejection, the titer of cytotoxic antibodies remains stable or tends to increase. LDH and alkaline phosphatase show characteristic changes that are considered sequels from destructed transplantate. The experiments show, aside from certain reservations, that the donor-host combination fox-dog is suitable to serve as preclinic model for human transplantation using xenogenous donors of organs, i. e. anthropoid primates.

Human adult lung fragments removed from macroscopically undamaged and anthracosis exempted zones of lungs of 20 pneumonectomies made for cancer, were tested for 25 enzymic activities. The location and intensities of these enzymic activities were different in the lung tissue components; The bronchial epithelia contained highly active LDH, MDH, SDH, NADH-TR and NADPH-TR, glucose-6-phosphate dehydrogenase, active hydroxyproline-2-epimerase, alkaline phosphatase. Ca2+-activated ATP-ase, and beta-galactosidase. Bronchial and vascular muscles presented intense activities of LDH, MDH and SDH of alkalinephosphatase, AMP-ase and Ca2+-activated ATP-ase, as well as of beta-galactosidase. The alveolar walls presented high activities of SDH, MDH and LDH, of alkaline and acid phosphatases, of beta-galactosidase and of Tween-40 and 60-esterases, of HEP, cytochrome-oxidase and peroxidase. The free alveolar macrophages were active for LDH, MDH, SDH, NADH-TR and NADPH-TR, G1-6-ph-DH, acid and alkaline phosphatase, cytochrome-oxidase and peroxidase, HEP, AMP-ase and Mg2+-activated ATP-ase, Tween-esterases, naphthol-ASD-acetate esterase, and beta-galactosidase. The endothelia contained high activities of alkaline phosphatase, of AMP-ase and Mg2+-activated ATPase, of LDH, MDH and SDH, and of beta-galactosidase. In bronchial lymphoid nodules it was the LDH, MDH, SDH, cytochrome-oxidase and peroxidase, HEP, alkaline phosphatase and AMP-ase, Tween-60-esterase and beta-galactosidase that were active. The interlobular areas of the lung presented intense activities of SDH, MDH, LDH, HEP and cytochrome-oxidase. The activities of the other tested enzymes were weaker or absent in the adult human lung components, the same as those of aminopeptidases which were present only in some free alveolar macrophages. The discussion of some relationships between these enzymic actitivies and the morphology of the human adult lung tissue asserted that the latter could not be considered as a "normal" tissue but as one overstrained by the components of blood and polluted air.

The histochemistry of the neural cells was studied in the submandibular ganglia of 5 Callithrix jacchus (3 males and 2 females) and 4 Callithrix penicillata (2 males and 2 females). These cells contain neutral mucopolysaccharides, nucleoproteins and lipidic materia, but are apparently devoid of glycogen. It is impossible to demonstrate in them any reactivity for UDPG-GT, phosphorylases, ATPase at pH 6.3, leucine aminopeptidase and alanyl aminopeptidas. The reaction for the other searched enzymes was as follows: weak (F-1,6-P Ald and cytochrome oxidase), weak to moderate (ADH, 6-P-GDH, ICDH, SDH, MDH, alpha-GPDH and beta-OHBDH), moderate (G-6-PDH, F-1,6-PA, LDH and GDH), moderate to strong (ATPase at pH 7.4, nonspecific esterase and acid phosphatase) and strong (G-6-PA, NADH2,-TR, NADPH2-TR, ATPase at pH 8.5 and 9.4 and alkaline phosphatase).

A prospective study was carried out in 25 patients following visceral angiography using, on average, 3.5 (2.3 to 4.3) ml/kg. of sodium methyl glucamine diatrizoate 76%. No significant changes were found in the liver enzymes (SGTP, LDH and alkaline phosphatase). On the other hand, there was a significant but temporary rise of serum creatinine from 0.9 +/- 0.2 mg% to 1.2 +/- 0.3 mg% as well as transient proteinuria (7 cases) and microhaematuria (6 cases). With the usual contrast doses for visceral angiography, the kidney appears to be the critical organ. In order to reduce the risks of renal complications, contrast doses should be kept to below 4 ml/kg. if possible; angiography should be carried out only if the patient is well hydrated and the indications for angiography should be particularly stringent if there is previous renal damage.

The epithelial cells in the taste buds of C. jacchus and C. penicillata show a moderate amount of ribonucleic acid an a concentration of a PAS-positive diastase-resistant material at their apical part. These cells are devoid of UDPG-GT, phosphorylases, G-6-PA, alanyl aminopeptidase, leucine aminopeptidase, cholinesterase and MAO; they present a weak reaction of F-1, 6-P Ald, LDH, SDH, MDH, cytochrome oxidase, beta-OHBDH, nonspecific esterase and acid phosphatase and a stronger reaction to ADH, NADPH2-TR, ATPases, alpha-GPDH, alkaline phosphatase, 5-nucleotidase and GDH. Although some enzymes (alkaline phosphatase, 5-nucleotidase and ATPases) have an almost uniform reactivity by the several taste buds, the other ones react with a lesser intensity in the smaller uniform reactivity by the several taste buds, the other ones react with a lesser intensity in the smaller taste buds of the fungiform papillae. As a rule the apical part of the cells shows a stronger enzymatic reactivity. The taste buds of the marmosets are penetrated by acetylcholinesterase positive nerve fibers whereas the autonomic ganglia in the connective tissue contain both-acetyl and butyrylcholinesterase.

Testis, epididymis and ductus deferens of the adult domestic fowl and male gonads of juvenile roosters have been studied by means of histochemical and histological methods. Testicular interstitial cells: According to enzyme-histochemical results oxidative energy production seems to be of minor importance. An extraordinarily high activity of lysosomal enzymes (acid phosphatase and esterases in the adult, esterases only in the immature) is observed. Positive reactions of 3beta-steroid-dehydrogenase and enzymes of the pentose phosphate cycle indicate steroid hormone production; the pathways of the steroid synthesis, however, are probably different in adult and immature testes. A remarkable LAP content of juvenile Leydig cells is a parameter of an increased protein metabolism. Areas of reserve cells: Focal accumulation of these cell types are observed in testis and epididymis of the immature and in the epididymis of the adult fowl. Reserve cells reveal distinct activities of LAP (prospective growth ability) and 3beta-HstDH (reserve capacity for steriod synthesis). All other enzymes studied react weakly, thus pointing to a generally low metabolic activity. Seminiferous tubules: The strong reaction of alkaline phosphatase in the peritubular cells may play a part in energy disposition for contractions. Sertoli cells of adult animals are rich in lysosomal enzymes and enzymes of the glycolytic chain but oxidoreductases react weaker than in mammalian Sertoli cells. This indicates that nutritive interactions between germ and Sertoli cells in birds are different from those in mammals: The basally orientated germ cells of birds contain strong activities of diaphorases, LDH, SDH, Cyto-Ox and seem to be metabolically rather indipendent from Sertoli cells.

Based on the hypothesis that beta lipoproteins have the ability to trap certain enzymes, an attempt was made to release these enzymes from the eventual beta lipoprotein blockade, by subjecting the serum to different processings such as: freezing-thawing (3 times), ultrasonation or treatment with Triton X100 or sodium desoxycholate. After the first two procedures an increase of serum LDH and alkaline phosphatase activities was observed in about half the sera investigated (normal and pathologic). In few cases of coronary heart disease (two out of 60), LDH activity reached a clearly pathologic level.

Serum enzyme activities were studied in 131 cases of hepatocellular carcinoma (HCC), 76 cases of metastatic liver carcinomas (MLC) and 234 cases of hepatic cirrhosis. SGOT was elevated above SGPT in most of the time in these patients, SGOT/SGPT was greater in HCC compared with other groups, and that this ratio increased during the preterminal period more markedly in patients with HCC because of the significant increase of SGOT in the face of relatively stable SGPT. Preterminal rises of alkaline phosphatase and LDH activities were more pronounced in MLC. Leucine aminopeptidase activity exhibited no characteristic feature of diagnostic value. Of the five enzymes, SGOT changes were more closely correlated with the growth of HCC; SGPT reflected more of the liver parenchymal damage while SGOT was probably accounted for in part by tumor-derived GOT. Other clinical and pathological implications are discussed.
