[identification and cytochemical study of an extranuclear basic protein in the spermatozoa of decapod crustaceans].extranuclear basic proteins have been detected in the capsule of the spermatozoa of three species of decapod crustaceans (nephrops norvegicus l., macrura; eupagurus bernhardus l., anomura; carcinus maenas penn., brachyura). their properties have been studied by cytochemical methods. their position inside the capsule of the spermatozoon has been specified with the aid of the electron microscope. present in a constant fashion in the three species cited, their relative importance is very variable. ...19676068078
single and multiple visual systems in arthropods.extraction of two visual pigments from crayfish eyes prompted an electrophysiological examination of the role of visual pigments in the compound eyes of six arthropods. the intact animals were used; in crayfishes isolated eyestalks also. thresholds were measured in terms of the absolute or relative numbers of photons per flash at various wavelengths needed to evoke a constant amplitude of electroretinogram, usually 50 microv. two species of crayfish, as well as the green crab, possess blue- and ...19685641632

transmissible disease, probably viral in origin, affecting the amebocytes of the european shore crab, carcinus maenas.a transmissible infection of the shore crab ("crabe enragée"), carcinus maenas, was discovered in one of about 700 of this species collected by the station biologique, roscoff, france. the infection has been transferred by subinoculation through four serial passages in crabs collected at roscoff and through six more passages in c. maenas collected at woods hole, mass. the agent causes abnormal cellular clotting, a drop in the peripheral amebocyte count, clumping of amebocytes in the peripheral t ...197116558026

alteration of cytochrome c oxidase activity during spermatogenesis in carcinus maenas.during spermatogenesis in the crab, carcinus maenas, mitochondria in the developing spermatids degenerate. in close association with mitochondrial fragments in late spermatids, an elaborate lattice-like complex of fused membranes is formed and lies in a position adjacent to the acrosome. mature sperm possess no mitochondria, but a whorl of membranes is present alongside the acrosome in the diffuse nucleus. to ascertain whether or not cytochrome c oxidase activity is lost as the mitochondria disi ...1975172239
[blood acid-base changes produced by variations of water oxygenation in the crab carcinus maenas (author's transl)].10 blood acid-base changes were studied at 17 degrees c in immersed crabs (carcinus maenas) exposed to hypoxic and hyperoxic conditions, by measuring the ph and the co2 partial pressure, pbco2, and by calculating the bicarbonate concentration. 20 hyperoxia first induces a marked respiratory acidosis with a rise of pbco2. this acidosis is compensated thereafter by a non-ventilatory increase of the blood buffer base concentration. these results are discussed in relation to the general problems con ...19754615
[ultrastructure of the blood cells present in the y organ of carcinus maenas l. (crustacea, decapoda)].ultrastructural characters of the hemocytes in the y organ of carcinus maenas lead us to assimilate these cells to the "granulocytes". in the degenerating glands, these hemocytes evolve towards a peculiar physiological state: they show a phagocytic activity which confers on them macrophagic properties.1975813850
[vesicles of the smooth endoplasmic reticulum in the y organ of carcinus maenas l. (crustacea, decapoda)].the smooth endoplasmic reticulum in the y organ cells consists of vesicular and tubular elements containing a slightly electron dense substance. the contents of these vesicles are released either at the gland surface or within the intercellular spaces. these processes which are concomitant with the hormonal activity preparatory to the molting, may represent the release of crustecdysone or of one of its precursors.1975813838
factors controlling the in vitro and in vivo oxygen affinity of the hemocyanin in the crab carcinus maenas (l.).the oxygen affinity of the hemocyanin of the crab carcinus maenas was studied in vitro by measuring the o2 partial pressure at 50% saturation, p50, at various conditions of ph, temperature and salt concentration. at alkaline ph, the hemocyanin exhibits a normal bohr effect, inverted below ph=ph0=6.9 at 15 degrees c. a rise of temperature provokes an increase of both p50 and ph0. within the physiological range, only ca++ and mg++ ions influence the oxygen affinity. both ions decrease p50, and mg+ ...1975241104
blood acid-base changes during experimental emersion and reimmersion of the intertidal crab carcinus maenas (l.).the time course of blood acid-base changes was studied in carcinus maenas during experimental emersion and reimmersion at 15 degrees c by measuring ph and pco2 and calculating bicarbonate concentration. during the first 4 hr of the emersion period, a marked rise of pco2 entails a respiratory acidosis which is progressively compensated by a slow increase of the bicarbonate concentration; this compensation is completed after about 100 hr and the steady state mean ph value approximates that found f ...1975238271
[effect of hypercapnia on the acid base states of the blood in the crab carcinus maenas (l.) (crustacea-decapoda)].when the crab carcinus maenas respires in hypercapnic water, a respiratory acidosis occurs, which is progressively compensated by a rise of the blood bicarbonate concentration. the co2 partial pressure in the blood increases in proportion to the change in ambient co2 partial pressure. therefore, the regulation of the acid-base status depends mainly on non-respiratory adjustments of the blood bicarbonate concentrations.1975239796
