    Notes: Abstract The classical conditioning of the behavioural effects of cocaine has been shown to contribute to behavioural sensitization. In the present experiments, it was demonstrated that the effects of cocaine in rats can be conditioned to contextual stimuli. Furthermore, sensitization to cocaine's locomotor effects were demonstrated, and shown to be context specific. Nimodipine (10 mg/kg, SC), an L-type dihydropyridine Ca2+ channel antagonist, appeared to completely block the establishment of conditioning of cocaine's effects, but only partially blocked sensitization to cocaine. Haloperidol (0.05 mg/kg, IP), a relatively specific D2 dopamine receptor antagonist, attenuated behavioral sensitization but had no influence on the establishment of the conditioned component of cocaine. These results indicate that the sensitization to, and the development of classical conditioning of, cocaine's behavioural effects can be pharmacologically dissociated, but that a non-associative process involved in sensitization is normally overridden by conditioning factors.

    Notes: Abstract The development of classical conditioning of cocaine's locomotor effects can be dissociated from the development of sensitization to cocaine by co-administration of haloperidol, a dopamine D2-like receptor antagonist, and nimodipine, an L-type calcium channel antagonist. The effects of these agents on theexpression of conditioning and sensitization are described in the present report. Rats were given injections of vehicle or cocaine (10 mg/kg, IP) for 10 days before placement in a specific context in which locomotor activity was recorded. Neither haloperidol (0.05 mg/kg, IP) nor nimodipine (10 mg/kg, SC) influenced the expression of classical conditioning of cocaine's locomotor effects to the situational context on a subsequent cocaine-free test. Combined treatment of rats with both drugs did block classical conditioning with cocaine. Nimodipine, but not haloperidol, blocked the expression of behavioural sensitization to cocaine after a cocaine challenge. It is concluded that the expression of cocaine-induced classical conditioning can be pharmacologically dissociated from the expression of behavioural sensitization to cocaine. Furthermore, the effects of nimodipine and haloperidol on the expression of conditioning and sensitization are different from their effects on the development of these phenomena.

    Formation and regression of the corpus luteum of the American alligator (Alligator mississippiensis) (1995)

    Notes: Luteal morphology of the American alligator is unique when compared to other reptiles but is similar to that of its phylogenetic relatives, the birds. The theca is extensively hypertrophied, but the granulosa never fills the cavity formed following the ovulation of the ovum. The formation of the corpus luteum (CL) is correlated with elevated plasma progesterone concentrations, which decline dramatically after oviposition with the onset of luteolysis. Unlike those of most other reptiles, the central luteal cell mass is composed of two cell types; one presumably is derived from the granulosa, whereas the other is from the theca interna. Both cell types are present throughout gravidity but only one cell type is seen during mid to late luteolysis. A significant decline in luteal volume occurs following oviposition and continues throughout the post-oviposition period. The fastest decline in luteal volume occurs in the month immediately after oviposition; this rate then slows. Luteolysis appears to continue for a year or more following oviposition, as distinct structures of luteal origin can still be identified in animals 9 months after oviposition. The size of persistent CL can be used to determine whether a given female oviposited during the previous nesting season. Females with CL having volumes greater than 0.2 cm2 or CL diameters greater than 0.4 cm were active the previous season. © 1995 Wiley-Liss, Inc.

    Studies on the effect of trypan blue in the pregnant armadillo, dasypus novemcinctusSupported by USPHS grants GM-10210 and HD-00400. (1965)

    Notes: Evidence is presented that the hemochorial placenta of the ninebanded armadillo, Dasypus novemcinctus, is permeable to trypan blue when this dye is injected subcutaneously into the mother during the postimplantation period. This permeability appears to be related to a time-dependent active process or is associated with the maturation of the fetal reticulo-endothelial system. Spectrophotometric analysis of serum proteins revealed alterations in the dye-injected mothers as well as in thalidomide-treated animals as compared to untreated controls. While it is difficult at present to estimate the stage of pregnancy under teratogenic study, it is felt that this unusual experimental animal warrants further study with other teratogenic agents.

    Surface coat material associated with the developing otic placode/vesicle in the chick (1988)

    Notes: Surface coat material (SCM) has been illustrated in association with the apical surfaces of numerous epithelia during morphogenesis. This study investigates the development of a SCM associated with the invaginating otic placode/vesicle in the chick. Glycoconjugate containing SCM was retained by the inclusion of cetylpyridinium chloride (CPC) in the fixative, histochemically visualized by using ruthenium red (RR) staining, and viewed by scanning (SEM) or transmission (TEM) electron microscopy. Initial characterization of the glycoconjugates present in this material was elucidated by using lectins conjugated to fluorescein isothiocyanate. Lectins utilized included concanavalin A (Con A), wheat germ agglutinin (WGA), and soybean agglutinin (SBA). Invagination of the otic placode was apparent as early as stage 12. By stage 15 the vesicle was beginning to separate from the surface ectoderm as evidenced by its aperture, which was altered in shape and reduced in size. All embryos fixed with glutaraldehyde containing either CPC or RR were shown to possess SCM associated with the surface ectoderm, particularly in the area of the otic placode/vesicle. Additional embryos were processed by cryofixation without prior alehyde fixation; these also exhibited SCM. All lectins labelled the epithelium of the otic placode/vesicle. However, their binding patterns were not identical. The binding of Con A and WGA remained constant over the stages studied, while SBA increased as the otic vesicle developed. The data clearly indicate that otic placode morphogenesis is accompanied by the synthesis of SCM rich in glycoconjugates.

    Notes: Pregnant rats were injected intraperitoneally with a teratogenic dose of trypan blue (14 mg/100 g or 20 mg/100 g body weight) on the eighth day of gestation. Fetal blood was collected from control and experimental fetuses on the twentieth day of pregnancy. Serum was obtained from pooled blood samples of two to three fetuses. Paper electrophoresis was carried out in a Spinco model R system using barbital buffer at pH 8.6. The paper strips were subsequently stained with bromphenol blue and their density measured in a Spinco Analytrol to determine the relative concentration of each component. Total protein was measured in a Bausch and Lomb Serum Protein Meter. The predominant malformations seen in abnormal fetuses were apparent anophthalmia, 59%; hydrocephalus, 37%; and exencephaly, 19%. Other malformations were noted but with less frequency. Twenty-day fetuses from trypan blue treated mothers had a significantly lower total protein concentration (1.50 g/100 ml) than control fetuses (1.95 g/100 ml). A comparison of the absolute protein concentration of the serum fractions revealed significant differences between control and experimental fetuses in beta globulin, alpha-1 globulin, and albumin. In each instance the absolute concentration was less in the fraction from fetuses of trypan blue treated mothers. Fetal gamma, alpha-2, and alpha-3 globulins were not affected by the maternal treatment.

    Partial purification of HLAMP-1 provides direct evidence for the multicomponent nature of the particulate matrix associated with cardiac mesenchyme formation (1997)

    Notes: H-LAMP-1 is a 283 kDa protein that is involved in the transformation of endothelial cells into mesenchyme within the AV canal and proximal outflow tract of the heart. This protein is part of the particulate matrix that has been suggested to be composed of multicomponent complexes that have been termed cardiac adherons. However, to date no direct evidence has been provided that these proteins are complexed into an adheron-like particle. This report provides the first such evidence by showing that purification of hLAMP-1, under gentle conditions, results in the isolation of multiple bands of similar molecular weight within the fractions that contain anti-hLAMP-1 activity.
