Abstract
Effects of chloramphenicol (antibiotic inhibiting complex-1 of respiratory chain) and thioamphenicol (TAP, a structural analog of CAP inactive on complex-1) were examined on cerebral energy metabolites and sleep-wake cycle architecture in rat. In the first group, animals were chronically equipped with a cranial surface resonator and (31)P spectroscopic measurements were performed using a 2 T magnetic resonance spectrometer (operating frequency 34.46 MHz). CAP administration (400 mg/kg, tail vein, light period) induced deficits in phosphocreatine (-30%, p < 0.01) and ATP (-40%, p < 0.01), whereas TAP (400 mg/kg) had no effect. In the second group, animals were chronically implanted with polygraphic electrodes for EEG and electromyogram recordings. CAP administered intraperitoneally at light-onset reduced rapid-eye movement (REM) sleep (-60% in the first 6 h of light period, p < 0.01), increased waking state (+65% in the first 6 h of light period, p < 0.01), and slightly affected slow-wave sleep (SWS). During waking state, theta and sigma power bands of the EEG were, respectively, increased and decreased (p < 0.05). During SWS, delta power band was reinforced (p < 0.05), while theta, alpha, and sigma bands were decreased (p < 0.05). No changes occurred during REM sleep. TAP had no effect on sleep-wake states and spectral components of the EEG. Overall, these data indicate that REM sleep occurrence is linked to an aerobic production of ATP.

Abstract
We studied the effects of chloramphenicol on brain glucose utilization and sleep-wake cycles in rat. After slightly anaesthetized animals were injected with [18F]fluoro-2-deoxy-D-glucose, we acquired time-concentration curves from three radiosensitive beta microprobes inserted into the right and left frontal cortices and the cerebellum, and applied a three-compartment model to calculate the cerebral metabolic rates for glucose. The sleep-wake cycle architecture was analysed in anaesthetic-free rats by recording electroencephalographic and electromyographic signals. Although chloramphenicol is a well-established inhibitor of oxidative phosphorylation, no compensatory increase in glucose utilization was detected in frontal cortex. Instead, chloramphenicol induced a significant 23% decrease in the regional cerebral metabolic rate for glucose. Such a metabolic response indicates a potential mismatch between energy supply and neuronal activity induced by chloramphenicol administration. Regarding sleep-wake states, chloramphenicol treatment was followed by a 64% increase in waking, a 20% decrease in slow-wave sleep, and a marked 59% loss in paradoxical sleep. Spectral analysis of the electroencephalogram indicates that chloramphenicol induces long-lasting modifications of delta-band power during slow-wave sleep.

Abstract
Owing to the lack of methods capable to monitor the energetic processes taking place within small brain regions (i.e. nucleus raphe dorsalis, nRD), the neurotoxicity of various categories of substances, including antibiotics and psycho-active drugs, still remains difficult to evaluate. Using an in vivo picosecond optical spectroscopy imaging method, we report that chloramphenicol (CAP), besides its well-known ability to inhibit the mitochondria protein synthesis, also influences the NADH/NAD+ redox processes of the respiratory chain. At a 200-mg/kg dose, CAP indeed produces a marked increase in the fluorescent signal of the nRD which, according to clear evidence, is likely to be related to the NADH concentration. This effect also implies an efficient inhibition of complex I of the respiratory chain by CAP. It refers to the mechanism through which the adverse effects of the antibiotic may take place. It could explain why paradoxical sleep, a state needing aerobic energy to occur, is suppressed after CAP administration. The present approach constitutes the first attempt to determine by fluorescence methods the effects of substances on deep brain structures of the freely moving animal. It points out that in vivo ultrafast optical methods are innovative and adequate tools for combined neurochemical and behavioural approaches.

Abstract
Intact vacuoles were isolated from petals of Hippeastrum and Tulipa (Wagner G.J. and Siegelman, H.W. (1975) Science 190, 1298--1299). The ATPase activity of fresh vacuole suspensions was found to be 2--3 times that of protoplasts from the same tissue. 70--80% of the ATPase activity of intact vacuoles was recovered in tonoplast preparations. The antibiotic Dio-9 at 6mug/10(6) vacuoles or protoplasts causes 40% inhibition. However, only the protoplast ATPase is sensitive to oligomycin. N,N'-dicyclohexylcarbodiimide (DCCD) slightly stimulates ATPase activity in both vacuole and protoplast suspensions, whereas ethyl-3-(3-dimethylaminopropyl carbodiimide) (EDAC) strongly inhibits. Spectrophotometric studies show that in the petal the vacuolar contents have a pH of 4.0 for Tuplipa and 4.3 for Hippeastrum, whereas the intact isolated vacuole has an internal pH of 7.0 (in pH 8.0 buffer) for (Tulipa and about 7.3 for Hippeastrum. Internal ion concentrations of 150, 46, 30, 30 and 6 mM were found for K+, Na+, Mg2+, Cl-, and Ca2+ respectively, which are about the same as those in protoplasts.

Abstract
1. The uncoupler-stimulated ATPase activity of castor bean endosperm mitochondria and submitchondrial particles has been studied. The rate of ATP hydrolysis catalyzed by intact mitochondria was slow and little enhanced by addition of uncouplers at the concentration required for uncoupling the oxidative phosphorylation. ATP-ase activity was stimulated at higher concentrations of uncouplers. 2. 1-Anilinonaphthalene 8-sulfonate fluorescence was decreased when the mitochondria were oxidizing succinate. Carbonylcyanide-p-trifluoromethoxyphenylhydrazone and antimycin reversed the succinate-induced fluorescence diminution. ATP did not induce the fluorescence response. 3. The addition of succinate, NADH or ascorbate/N,N,N'-N'-tetramethyl-p-phenylenediamine as electron donor induced high ATPase activity in the presence of low concentrations of uncouplers. Stimulating effect of uncouplers was completely abolished by further addition of antimycin. 4. Submitochondrial particles were prepared by sonication. The particles catalyzed a rapid hydrolysis of ATP and carbonylcyanide-p-trifluoromethoxyphenylhydrazone at 10-8 M did not stimulate the ATPase activity. Addition of succinate induced uncoupler-stimulated ATPase activity. The effect of succinate was completely abolished by further addition of antimycin. 5. The treatment of submitochondrial particles by trypsin or high pH also induced uncoupler-stimulated ATPase activity. 6. The above results were interpreted to indicate that ATPase inhibitor regulated the back-flow reaction of mitochondrial oxidative phosphorylation.

Abstract
The stimulation by cyclic AMP of steroidogenesis in rat adrenal cells isolated by trypsin treatment was inhibited by D-threo-chloramphenicol and by its L-threo-isomer. The former is an inhibitor of mitochondrial protein synthesis while the latter is not. Both substances, at concentrations which inhibit steroidogenesis, inhibit amino acid incorporation into the proteins of microsomes. Inhibition in other subcellular fractions also occurs depending on the isomer and its concentration. In no case was there a preferential inhibition of amino acid incorporation into mitochondrial proteins. Carbomycin, another inhibitor of mitochondrial protein synthesis, gave similar results. In addition, subfractionation of mitochondria in these experiments revealed no preferential inhibition of amino acid incorporation into the proteins of either the soluble of membrane fractions of this organelle. The above results were obtained at several concentrations of the inhibitors when only partial inhibition of steroidogenesis was present. Both isomers of chloramphenicol inhibited steroidogenesis in a cell-free system to an extent equal to that found with cyclic AMP-stimulated steroidogenesis in intact cells. It is concluded that these inhibitors of mitochondrial protein synthesis have multiple metabolic effects in adrenal cells.

Abstract
The distribution of ATP-ase and other nucleotide phosphatases has been studied in young root tips of maize, barley and broad bean using frozen and paraffin sections stained by standard lead sulphide precipitation procedures. High ATP-ase activity was found at the root and cell surface which is in agreement with previous biochemical studies using excised roots and cell wall preparations. Staining was also found in the nuclei and at particulate sites in the cytoplasm. Differences were observed between the present work and the staining pattern obtained for β-glycerophosphatase, and between ATP-ase staining in the three roots studied. These results are discussed in relation to the possible physiological activity of the enzymes and to the differences found between earlier histochemical studies of ATP-ase activity.

Abstract
The accumulation and behavior of various amino acids in the pool of Pseudomonas aeruginosa (ATCC 9027) were investigated. Patterns of pool formation and maintenance varied with different amino acids tested and were dependent, to a considerable extent, upon the ability of the organism to catabolize the particular amino acid. The establishment of steady-state amino acid pool levels depended upon the activity of the amino acid permease involved and upon the rate of protein synthesis. The presence of a relatively large specific amino acid pool did not affect the formation of a pool of a structurally different amino acid, and a preformed steady-state pool was not displaced by structurally unrelated amino acids. Steady-state amino acid pools decreased rapidly in the presence of inhibitors of energy metabolism and at 0 C. Steady-state internal amino acid pools were found to be in equilibrium with the corresponding external amino acid, present at low levels. A multiplicity of proline pools was demonstrated.

Abstract
D-threo-chloramphenicol at concentrations ranging from 1000 to 3000 μg/ml stimulated the germination of the light-sensitive seeds of the lettuce (Lactuca sativa L.) varieties Attractie and Grand Rapids. This stimulatory effect of chloramphenicol was markedly temperature dependent, increasing with decrereasing temperature. Seeds showed little response to chloramphenicol at temperatures of 28°C and above except in the case of light treated Attractie seed. The failure of one batch of Grand Rapids seed to respond to chloramphenicol was associated with the low degree of dormancy in this batch.When the germination of half-seeds or intact excised embryos of Attractie seed was inhibited osmotically with 0.15 M NaCl a stimulatory response to chloramphenicol was obtained suggesting that the site of action was in the embryo itself.Other inhibitors of protein synthesis, cycloheximide, puromycin and p-fluorophenylalanine, did not stimulate germination. Cycloheximide at concentrations of 10 μg/ml and above inhibited germination whereas puromycin and p-fluorophenylalanine were relatively ineffective as germination inhibitors.

Abstract
L-threo chloramphenicol and actinomycin D act like D-chloramphenicol in being able to promote germination of light-requiring seeds of Lactuca sativa in darkness. The two isomers of chloramphenicol at relatively low concentrations also prevent the development of skotodormancy. Protein synthesis, measured by the incorporation of tritiated leucine, occurs in dormant seeds in darkness; evidence suggests that this occurs most intensively in the endosperm. The stimulation of germination by chloramphenicol and actinomycin D is preceded by a marked reduction in protein synthesis. It is suggested that these substances act by arresting an inhibitory process which requires protein synthesis.
