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.

Cytochemical, biochemical and disc-elektrophoretical studies are done on a patient with Di Guglielmo-syndrom. Cytochemical tests showed the wellknown results as: activity of acid phosphatase and alpha-naphthylacetatesterase at their typical sites, deposition of PAS- and Turnbull-positive material. Biochemical findings are done on LDH, cholinesterase, alkaline and acid phosphatase, G-6-PDH and pyruvatkinase. Abnormal high level of fetal hemoglobin was found only once during the whole observation. There was also an alteration in the isoenzym pattern of the acid phosphatase. The de- or increase at the biochemical examinations, the fact of fetal hemoglobin and the variation at the isoenzymes may be due to the changing in distribution of erythropoetic and granulopoetic cells.

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 anti-inflammatory activity of FL 70, a derivative of 2,5-dihydroxy-benzoic acid, was examined in a number of conventional experimental models. In addition, FL-70 was tested for its inhibitory action on enzymes. The results were as follows: 1. The induction of a local inflammatory reaction and the subsequent i.v. injection of trypan blue showed that FL 70 reduces the capillary permeability. 2, FL-70 significantly suppresses exudation in the formalin-induced peritonitis of the rat. 3. A slight inhibition of an edema in the footpad of the rat induced by formalin-dextran was not shown to be statistically significant. 4. Local swelling could be markedly inhibited in the turpentine-oil induced inflammatory reaction of the rabbit. 5. Exudation and formation of granulomatous tissue was inhibited in Selye's granuloma. 6. FL-70 markedly inhibited the local inflammatory reaction accompanying the cutaneous reaction in experimental vaccinia infection of the rabbit skin. The size of the infiltration after intracutaneous infection of the virus was not reduced. 7. FL-70 could not prevent the onset of clinical signs, if administered in experimental allergic encephalitis. 8. The activity of acid phosphatase was inhibited by FL-70. Alcaline phosphatase, cholinesterase, leucin aminopeptidase, glucose-6- phosphatase-dehydrogenase (G-6-PDH), trypsin and chymotrypsin were unaffe-ted. FL-70 inhibits the following, G-6-PDH activated reduction process: glucose-6-phosphate (see article).

Elevation of serum-angiotensin-converting enzyme (serum ACE) in patients with active sarcoidosis was confirmed in a total of 64 subjects with a mean serum ACE of 15.76+/-7.4 units compared with 6.05+/-2.0 units in 194 patients with other types of respiratory disease. Resolution of the sarcoidosis disease state or therapeutic control with adequate doses of corticosteroids (15 mg prednisone daily) brought the elevated serum ACE levels down into the normal range. A longitudinal study of serum ACE activity was found to be an effective way of judging the therapeutic efficacy of various steroid dosage levels. No other disease state involved in the differential diagnosis of sarcoidosis was found to have elevations of serum ACE activity. However, 6 patients with Gaucher's disease did have elevated serum ACE activity that ranged well above the usual level seen even in patients with sarcoidosis. The two diseases could be readily distinguished in the laboratory by elevated serum acid phosphatase activity in most cases of Gaucher's disease. It would appear that detection of elevated serum ACE levels can be a useful procedure for confirming a diagnosis of active sarcoidosis and for judging the therapeutic response.

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.

The effects of stress due to brief (4--5 min) ether and pentobarbital anesthesia vs. decapitation on assays of seven enzymes in homogenates of synovium, articular and epiphyseal cartilage, and metaphyseal and cortical bone were compared. Etherization caused twofold changes in synovial and articular cartilage G-6-PDH, LDH, CPK, glutamic DH, and ICDH based on tissue dry weight and DNA content. Pentobarbital anesthesia produced only slightly lower activities, per gram DNA, of LDH, acid phosphatase, and glutamic-DH in cortical bone. Epiphyseal cartilage metabolism was unaffected by either mode of anesthesia. No difference could be detected between levels of enzyme activities of the several tissues taken from rats that had been decapitated or anesthetized with pentobarbital. The changes in enzyme activities suggested that pentobarbital was non-stressful and appropriate to metabolic studies in the skeleton.

By in vitro assay, 6 important enzymatic activities of human skin homogenates were determined following an incubation with D-penicillamine in concentrations between 10(-4) and 10 mg/ml, i.e. 67 X 10(-5) and 67 mM/l. The following enzymatic activities were recorded: lactate dehydrogenase (LDH), glucose-6-phosphate dehydrogenase (G-6-PDH), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), alkaline phosphatase (AP), acid phosphatase (AcP), and "leucine aminopeptidase" (LAP). A dose-dependent activation by D-penicillamine occurred in the case of G-6-PDH- and AcP-activities, a dose-dependent inhibition by D-penicillamine was found with AP- and GAPDH-activities. LDH- and LAP-activities remained unchanged in the presence of D-penicillamine in concentrations up to 10 mg/ml (67 mM/l). From the data of pharmacokinetic studies in rats it may be concluded that concentrations of D-penicillamine which influence enzymatic activities may easily be reached in vivo, under the conditions of treating rheumatoid arthritis and Morbus Wilson. The biochemical actions of D-penicillamine are briefly discussed with secial regard to dermatological therapy and dermatological unwanted side-effects.

Male weanling Wistar rats received 200 micrograms/ml of mercury (Hg), as HgCl2, in drinking water for 180 days. At the end of the treatment, systemic arterial blood pressure was augmented, cardiac inotropism was reduced, and heart rate was unchanged. Light and electron microscopical studies of the kidney showed a mesangial proliferative glomerulonephritis in about 80% of the glomeruli. Tubular cells showed reduction of the acid phosphatase activity, which was related to functional abnormalities of the lysosomes. In the 24 hour urine samples of the Hg exposed rats, there was slight reduction of kallikrein activity, but evident proteinuria was not present in all samples. Plasma renin activity was reduced, that of angiotensin I-converting enzyme was augmented, and plasma aldosterone concentrations were unchanged. Mercury was accumulated mostly in the kidney of the Hg treated animals; and the content of Hg in the heart was higher than in the brain. These data show that chronic exposure to Hg acts on the kidney with complex mechanisms of toxicity; these contribute to modify systemic haemodynamics.
