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.

Scolices and brood capsules of healthy hydatid cysts from lungs of human patients were studied with histochemical and histoenzymatic methods. The subtegumental and flame cells were sepcially rich in glycogen, RNA and some dehydrogenases such as SDH, MDH, NADH-reductase and G-6-PDH. The rostellar zone or invaginated pole, an area of marked contractile movements, showed intense activity in ATP'ase and simple esterase. The so-called excretory pole shows strong activity in simple esterases, lipase, beta-HBH, alpha-GDH and NADPH-reductase. Lipids are also abundant in this zone implying the important role of this metabolic path in the development of the parasite. Intense activity in alkaline phosphatase was observed in cells associated to the calcereous corpuscles. The largest corpuscles were devoid of enzymatic activity. The enzyme could play some role in the calcification of the corpuscles. Wide enzymatic variations are described according to morphology being orthoscolices the most rich in enzyme activity. Accumulations of small cells surrounded by specialized cells on the germinal membrane are interpreted as the origin or "embryo" of brood capsules. Some enzymes detected in the wall of mature brood capsules depicted alternating types of cells. Some of them are positive for ATP'ase that may be related to active transport of substances across the brood capsule wall. The intenst ATP'ase activity at the stalks of scolices may be similarly interpreted. However, a miosine-like activity is a more feasible explanation since this area showed striking contractile movements in vivo.

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).

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.

Rats were made to drink D2O mixed water (30: 70) for 6 weeks in order to study the biological effects of orally administered D2O on the liver. Heavy water administration results in gradual decrease in the body weight whereas the liver showed marginal increase in weight throughout the experimental period. Phosphatases and dehydrogenases were analyzed biochemically. Acid phosphatase, glucose-6-phosphatase and adenosine triphosphatase registered fall in contrast to alkaline phosphatase, SDH and LDH, all of which showed a definite increase. Lipids, nucleic acids and proteins, estimated biochemically, gradually decreased throughout the experimental period in response to D2O feeding.

The structure and histochemistry of the palmar and plantar skin were studied in four adult male marmosets (two Callithrix jacchus and two Callithrix penicillata). In this skin there exist well-developed epidermal ridges, to which are attached one or two ducts of sweat glands. A thick stratum corneum can be seen in the epidermis, while a distinct stratum lucidum cannot be isolated from the other layers. The stratum granulosum is constituted by one or three layers of cells containing keratohyalin granules. Melanin granulations are mainly concentrated in the basal cells of the epidermal ridges. Dendritic melanocytes and amelanotic melanocytes containing alkaline phosphatase are found among the epidermal cells. Glycogen, UDPG-GT and phosphorylases are mainly present in the middle and lower Malpighian cells of the epidermal ridges. Alkaline phosphatase, ATPase, alanyl amino-peptidase and leucine aminopeptidase were absent in the epidermal cells. SDH, cytochrome oxidase, MAO and a certain number of NAD-dependent dehydrogenases (LDH, ADH, MDH, alpha-GPDH, beta-OHBDH and GDH) showed a stronger reactivity in the basal cells and Malpighian layer. The NADP-dependent enzymes (G-6-PDH, 6-PGDH, cis-aconistase and ICDH) were more reactive in the upper Malpighian layer and stratum granulosum. The stratum corneum showed some acid phosphatase and nonspecific esterase reactivity. The collagenous fibers intertwined with a small number of very thin elastic ones and a larger amount of reticular fibers run almost parallel to the epidermal ridges in the papillary body. In the reticular dermis some fibers are disposed transversely to the epidermal ridges. Meissner corpuscles reactive to butyrylcholinesterase, acetylcholinesterase, nonspecific esterase and G-6-PA are disposed at regular intervals and frequently at each side of the epidermal ridges. Pacinian corpuscles were found only in the hypodermis. The eccrine sweat glands contain glycogen, UDPG-GT and phosphorylase in their secretory, ductal and myoepithelial cells. The secretory part shows a uniform reactivity for every dehydrogenase because it contains only one type of cells (clear cells). The intraepidermal segment of the ducts shows a stronger reactivity to nonspecific esterase and NADP-dependent dehydrogenases than the epithelial cells around it.

Histoenzymologic differences between the parotid, paramandibular and submandibular glands were studied in six Callithrix jacchus (four males and two females) and four Callithrix penicillata (three males and one female). The acinous cells of the paramandibular glands showed a stronger reactivity for the diaphorases (NADH2-TR and NADPH2-TR) and for a certain group of enzymes of the carbohydrate metabolism (F-1-6P Ald, LDH, ADH, G-6-PDH and 6-PGDH), lipid metabolism (alpha-GPDH, beta-OHBDH, alkaline phosphatase and acid phosphatase), protein metabolism (alanyl aminopeptidase, leucine aminopeptidase and GDH) and respiratory chain (cris-aconitase and ICDH). The nonspecific esterase was more reactive in the basal part of of the mucous cells of the submandibular glands. Conversely, some enzymes of the respiratory chain (SDH, cytochrome oxidase and ATPases) showed a stronger reactivity in the serous cells of the parotid and submandibular glands. The paramandibular glands exhibited a lesser autonomic innervation than the parotid and submandibular.

A histochemical evaluation of hydroxysteroid dehydrogenase (OH-SDH) activity in porcine granulosa cells isolated from preovulatory ovarian follicles and cultured in cell culture is presented. Granulosa cells during in vitro culture showed activity of enzymes participating in steroid biosynthesis. High activity of delta-5,3beta OH-SDH and glucose-6-phosphate dehydrogenase as well as the activity of alkaline phosphatase, appearing in the course of culture, could be evidence of progressive luteinization of the cells. 17beta OH-SDH activity was lower and exhibited strong fluctuations. 20alpha OH-SDH was similarly low. Gonadotropic hormones caused the increase of synthesis and accumulation of intracellular lipids, and stimulated alkaline and acid phosphatase and dehydrogenase activity. Luteinizing hormone had the most visible effect.
