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.

Elaboration of a semiautomated kinetic test on LKB 8600 apparatus for
ATPase
is described, using the PK-
LDH
system. As optimal ionic conditions 3 mmol-1 - minus 1 potassium chloride and 100 mmol-1 - minus 1 sodium chloride are proposed for measurement of (Na+-K+)-
ATPase
activities of rat intestinal brush borders. NH+4 can substitute for K+. The coefficients of variation of the method are 2.4% for Mg2+-ATPase and 4.9% for (Na+-K+)-
ATPase
determinations.

The activities of the Na+--K+-
ATPase
, succinic dehydrogenase (SDH/, lactic dehydrogenase (
LDH
/ and glucose-6-phosphat dehydrogenase (G-6-PDH/ were studied in the cortex outer and inner medulla of the kidneys of rats with spontaneous hypertension (SHR) and were compared with those of control normotensive Wistar rats. The SHR aged 6--8 weeks had durint the prehypertensive and the early hypertensive stage the same enzymatic activities as control rats. Rats with a steady SH aged 16-22 weeks had low specific activity of the, Na+--K+-
ATPase
, SDH and
LDH
in the outer medulla. The latter can be associated with decreased intensity of the energy metabolism and a reduction of the active sodium transport in the ascending limb of the loop of Henle in the SHR rats and cold cause the phenomenon of exaggerated natriuresis characteristic of hypertension.

The effect of the anabolic hormone 19-nortestosterone propionate (Superanabolon Spofa) on the metabolism of chronically ischaemic striated muscle (anterior tibial m.) was studied in a described model in the rat. Metabolic changes were estimated in terms of the activities of a number of enzymes in muscle fibres. Enzyme activities (AcP,
ATPase
, CE,
LDH
, MDH) were determined both biochemically and histochemically excepting SDH, which was determined only by the histochemical way. Morphological changes were investigated by routine histology. Administration of 19-nortestosterone propionate prevented enzymatic changes which are typical for chronic ischaemia, primarily the decrease in the activities of dehydrogenases of Krebs' cycle tricarboxylic acides (MDH, SDH). In addition, the ratio of red to white muscle fibres increased. Administration of anabolic hormone has a similar favourable action on ischaemic muscle as training, studied previously.

The rats with chronic renal hypertension caused by constricting one renal artery, exhibit a decrease in the activity of Na-K-
ATPase
in the outer medulla of the "untouched" kidney, as compared to this activity in the kidneys of intact normotensive rats and in the "untouched" kidney of the rats where renal artery constriction did not result in hypertension. There were no differences between the control normotensive Wistar rats and the spontaneously hypertensive rats (SHR) in the prehypertensive and early hypertensive stages (at the age of 6-8 weeks) as far as the activities of Na-K-
ATPase
and oxidoreductases (SDH and
LDH
) in the renal cortex, the outer and inner medulla are concerned. The spontaneously hypertensive rats with chronic hypertension had at the age of 16-20 and 27-29 weeks lower activity of Na-K-
ATPase
, SDH, and
LDH
in the outer renal medulla than the control normotensive Wistar rats. The experimental results indicate that in chronic arterial hypertension there is a decrease in the activity of Na-K-
ATPase
, in the outer renal medulla, which suggests a reduction in the resorpo sodium and water.

The activities of several glycolytic enzymes (hexokinase, phosphofructokinase, pyruvate kinase, lactate dehydrogenase) as well as glycerol-1-phosphate dehydrogenase and (Mg2+)
ATPase
in normal cerebrospinal fluid (CSF) and blood plasma samples, from 12 healthy infants, aged 2-18 months, and in supernatants from brain tissue slices, taken during neurosurgical operations from infants of the same range of age were estimated. The values obtained confirm the high activity of the above enzymes found in animal brains, and indicate an independence of these activities in blood plasma and CSF. The origin of the activities of the investigated enzymes in CSF seems to be mainly, if not, exclusively, from brain tissue. This might be useful for detection of brain tissue damage as was earlier proven with
LDH
activity in CSF.

Skeletal muscles of flight rats showed no changes in the content of glycogen,
adenosine triphosphatase
activity of myosin and protein content in protein fractions (except the T fraction where the protein content increased on the 1st and returned to the normal on the 26th postflight day). On the 1st postflight day activities of aminotransferases and lactate dehydrogenase of sarcoplasmatic proteins were elevated and the isoenzyme spectrum of
LDH
was changed as if in muscular atrophy. The amount of free amino acids in muscles was lowered. On the 26 the postflight day the enzymic activity of sarcoplasmatic proteins remained increased whereas the isoenzyme spectrum of
LDH
returned to the normal and the amount of free amino acids grew significantly. In the microsomal fraction of muscles the phospholipid content decreased on the 1st and returned to the normal on the 26th postflight day.

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).

Cryostat sections incubated for myofibrillar
ATPase
, SDH,
LDH
, and alpha-GPDH as well as p-phenylene-diamine stained semithin sections were used to define muscle fibre types in the trunk musculature of the cod (Gadus morhua, L.). Three zones (superficial, intermediate, deep) containing different muscle fibre types are present within both epaxial and hypaxial parts of each myomere subjacent to the lateral line. Atypical relations concerning myofibrillar
ATPase
activity probably reflects instability of myosin during storage of frozen tissue. The histochemical reaction does not distinguish between myofibrillar and mitochondrial ATPase in cod muscle. Based on
ATPase
and SDH activities, seven different histochemical profiles of muscle fibres can be identified in trunk musculature of this teleost fish. Attempts to homologize these fibre types with those in cyclostomes or those in higher animals proved futile. The higher number of histochemically defined muscle fibre types in cod might be explained by developmental processes and an admixture of immature fibres throughout life.
