A Probiotic Targets Bile Acids Metabolism to Alleviate Ulcerative Colitis by Reducing Conjugated Bile Acids

SCOPE

Gut microbiota (GM) dysbiosis and dysregulated bile acids (BAs) metabolism have been linked to ulcerative colitis (UC) pathogenesis. The possibility of utilizing live probiotics with a defined BAs-metabolizing capability to modify the composition BAs for UC treatment remains unexplored.

METHODS AND RESULTS

In this study, Strain GR-4 is sourced from traditional Chinese fermented food, "Jiangshui," and demonstrated the ability to deconjugate two common conjugated BAs by over 69% and 98.47%, respectively. It administers strain GR-4 to dextran sulfate sodium (DSS)-induced UC mice, and observes an overall alleviation of UC symptoms, as evidence by improved colon morphology, reduces inflammation and oxidative stress, and restores intestinal barrier function. Importantly, these effects are reliant on an intact commensal microbiota, as depletion of GM mitigated GR-4s efficacy. Metabolomics analysis unveils a decline in conjugated BAs and an increase in secondary BAs following GR-4 administration. GM analysis indicates that GR-4 selectively enriches bacterial taxa linked to BAs metabolism, enhancing GM's capacity to modify BAs.

CONCLUSION

This research demonstrates the potential for natural fermented foods and probiotics to effectively manipulate BAs composition, including conjugated and secondary BAs, to alleviate UC symptoms, underscoring the benefits of these approaches for gut health.

Anti-hyperglycemic and anti-hyperlipidemic effects of a methanolic extract of Debregeasia salicifolia in Alloxan-induced diabetic albino mice

Diabetes mellitus (DM), an endocrine syndrome characterized by high blood glucose levels due to abrogated insulin activity. The existing treatments for DM have side effects and varying degrees of efficacy. Therefore, it is paramount that novel approaches be developed to enhance the management of DM. Therapeutic plants have been accredited as having comparatively high efficacy with fewer adverse effects. The current study aims to elucidate the phytochemical profile, anti-hyperlipidemic, and anti-diabetic effects of methanolic extract D. salicifolia (leaves) in Alloxan-induced diabetic mice. Alloxan was injected intraperitoneally (150 mg kg-1, b.w), to induced diabetes in mice. The mice were divided into three groups (n=10). Group 1 (normal control) received normal food and purified water, Group II (diabetic control) received regular feed and clean water and group III (diabetic treated) received a methanolic extract of the plant (300 mg kg-1) for 28 days with a typical diet and clean water throughout the experiment. Blood samples were collected to checked serum glucose and concentration of LDL, TC, TG. The extract demonstrated significant antihyperglycemic activity (P<0.05), whereas improvements in mice's body weight and lipid profiles were observed after treatment with the extract. This study establishes that the extract has high efficacy with comparatively less toxicity that can be used for DM management.

Comparative analysis of various sources of selenium on the growth performance and antioxidant status in broilers under heat stress

The supplementation of Selenium-enriched probiotics is effective in reducing oxidative stress and maintaining meat quality stability in broiler chicken especially under heat stress. An experimental study was conducted to perform Comparative analysis of Selenium yeast with inorganic Se in broilers under heat stress. A total of 120 broilers chicks of one day were assigned to 4 groups each consisting 30 chicks fed on same basal diet but different selenium sources. The basal diet of group D1 was not supplemented with Se source (Negative control), group D2 basal diet was supplemented with inorganic selenium (Sodium selenite 0.22mg/Kg starter phase and 0.15mg/Kg finisher phase), group D3 basal diet was supplemented with commercially available organic selenium (Seleno-methionine 0.22mg/Kg starter phase and 0.15mg/Kg finisher phase) and group D4 basal diet was supplemented with self-developed organic selenium (Se-enriched yeast 0.22mg/Kg starter phase and 0.15mg/Kg finisher phase). The performance parameters i.e. feed intake (FI), live body weight (BW) and FCR were not significantly (p>0.05) effected by selenium supplementation in the starter phase but were significantly (p<0.05) effected in the finisher phase. Selenium supplementation significantly (p<0.05) effected serum Se level in different supplemented groups. Higher serum Se value (58.20±0.06) was recorded in D4 group. Similarly significantly lower selenium value was recorded for D4 and higher was recorded for D1 (11.36±0.08). However lower serum Paraoxonase (PON) value was recorded for D4 (13.24±0.01) and higher for D1 (13.33±0.03). Comparatively self-developed Se enriched yeast increased the Se accumulation and improved antioxidant system. Glutathione peroxidase (GPx) was found higher in D4 (12.333±0.03) followed by D3, D2 and D1 respectively. Whereas superoxide dismutase (SOD) was significantly lower (p<0.05) in D4 (0.1437±0.003) followed by D3 (0.1457±0.002). Selenium supplementation increased the bird's survival rate. Birds fed on Se enriched yeast showed higher Se deposition and better antioxidant capacity as compared to other sources of selenium. Se-enriched yeast displayed an improved result on Se deposition in tissues, and oxidative capacity, meat tenderness and immune response level as compared to other sources of selenium.

Galanin expression in adult human dorsal root ganglion neurons: initial observations

Human dorsal root ganglia (DRGs) were obtained during various procedures and processed for single and double in situ hybridisation using oligonucleotide probes complementary to three peptide mRNAs. Some postmortem ganglia were also analysed. In donor (unlesioned) DRGs 12.5% of the neuron profiles (NPs) were galanin mRNA-positive (mRNA(+)), 47.5% calcitonin gene-related peptide (CGRP) mRNA(+) and 32.7% substance P mRNA(+). The corresponding percentages for cervical/thoracic DRGs from patients suffering from severe brachial plexus injury were 32.8%, 57.4% and 34.5%, respectively. In these DRGs a high proportion of the galanin mRNA(+) NPs contained CGRP mRNA and substance P mRNA. In DRGs from a patient with migraine-like pain a comparatively small proportion expressed galanin, whereas in DRGs from a herpes zoster patient galanin mRNA(+) NPs were comparatively more frequent. The results from human postmortem DRGs revealed only weak peptide mRNA signals. The present results demonstrate that galanin is expressed in DRGs not only in a number of animal species including monkey as previously shown, but also in a considerable proportion of human DRG neurons, often together with CGRP and substance P, and mostly in small neurons. Thus, galanin may play a role in processing of sensory information, especially pain, in human DRGs and dorsal horn. However, to what extent a similarly dramatic upregulation of galanin expression can be seen after peripheral nerve lesion in man, as has been reported for rat, mouse and monkey, remains to be analysed.

[Pulmonary infection induced by Mycobacterium intracellulare in 2 sisters: a biomolecular study of the isolates]

Patient 1 was an 82-year-old woman without symptoms who had been admitted to the hospital because of abnormal shadows on a chest X ray film. The chest X ray showed a round opacity in the right middle lung field and air-space consolidation in the right lower lung field. A computed tomographic (CT) scan showed a nodular opacity with satellite lesions in the right middle lobe and bronchiectasis in the right middle lobe and left lingular segment. Bronchial lavage yielded Mycobacterium intracellulare. Patient 2 was the 77-year-old sister of Patient 1. She had productive cough and fatigue, and chest X ray films and CT scans showed air-space consolidation with a huge cavity in the left upper lobe. M. intracellulare was isolated repeatedly from sputum samples. Pulsed-field gel electrophoresis disclosed similar large restriction fragment patterns of genomic DNA in 2 strains of the bacterium isolated from both sisters, indicating that the sisters had been infected by genetically close strains. Cross-infection or infection from the same environmental source were suspected.

Galanin-R1 receptor mRNA expression in the hypothalamus of the Brattelboro rat

Using in situ hybridization the regulation of mRNA encoding the galanin receptor R1 was investigated in the mutant Brattelboro (diabetes insipidus) rat. We here report an increase of the galanin receptor R1 mRNA levels in the hypothalamic supraoptic and paraventricular nuclei of the mutant strains. The increase seemed to be confined to magnocellular neurons, since no changes were detected in galanin receptor R1 mRNA levels in the extra-hypothalamic nucleus of the olfactory tract. The results confirm that osmotic stimulation induces up-regulation of galanin receptor R1 mRNA levels. This may increase the sensitivity to galanin peptide, the endogenous ligand for this receptor.

[A study of beta-lactamase activity of mycobacteria and clinical trial of penicillin/beta-lactamase inhibitor combinations in the treatment of drug-resistant Mycobacterium tuberculosis]

Beta-lactamase activity was determined using a nitrocefin disc method on 34 Mycobacterium tuberculosis (M. tuberculosis) strains and 13 nontuberculous mycobacteria strains. In the 34 M. tuberculosis strains, 23 strains showed beta-lactamase activity. In 10 Mycobacterium avium complex strains, no beta-lactamase activity was detected. In the Mycobacterium chelonae strains, all three strains examined showed strong beta-lactamase activity. No correlation was found between beta-lactamase activity and resistance to anti-tuberculous chemotherapeutic agents. Four patients who were persistently positive for multi-drug-resistant M. tuberculosis (MDR-TB) on sputum and positive in beta-lactamase activity, were treated with penicillin/beta-lactamase inhibitor combinations. In two cases, the trials were discontinued because of diarrhea; the trials were continued in the remaining two for four months, but the MDR-TB was positive during the course of the therapy. Effectiveness of the therapy with penicillin/beta-lactamase inhibitor combinations against M. tuberculosis was obscure, although many of M. tuberculosis examined showed beta-lactamase activity.

Galanin-R1 receptor in anterior and mid-hypothalamus: distribution and regulation

The distribution and regulation of galanin-R1 receptor (GAL-R1-R) mRNA has been studied in the anterior and mid-diencephalon by using in situ hybridization. Moreover, possible colocalization of GAL-R1-R mRNA and prepro-galanin or vasopressin mRNAs has been analyzed at the cellular level using double in situ hybridization methodology. Many nuclei in the hypothalamus expressed GAL-R1-R mRNA, including the paraventricular nucleus (PVN) and the supraoptic nucleus (SON). Strong expression was also seen in the same sections in various areas outside of the diencephalon. The distribution patterns are similar to those described in earlier studies. Double labeling experiments showed GAL-R1-R mRNA in vasopressin neurons in the PVN and SON. Moreover, GAL-R1-R mRNA and prepro-galanin mRNA were colocalized in several hypothalamic nuclei. GAL-R1-R mRNA levels showed a high degree of plasticity. Thus, salt loading resulted in a marked increase in GAL-R1-R mRNA levels in the PVN and SON and a moderate decrease was seen during lactation. In contrast, hypophysectomy caused a decrease in GAL-R1-R mRNA levels. Differential effects of colchicine were recorded with a decrease of GAL-R1-R mRNA in the magnocellular hypothalamic neurons. After salt loading or during lactation, GAL-R1-R mRNA and prepro-galanin mRNA were regulated in parallel, whereas their levels changed in opposite directions after hypophysectomy and colchicine injection. In conclusion, GAL-R1-Rs are present in several hypothalamic nuclei, partly in neurons synthesizing galanin. The receptors are regulated in a specific fashion in the various nuclei, depending on the stimulus applied. The results suggest that the effect of galanin in the hypothalamus partly depends on the state of receptor expression.

[A clinical study on the background of patients with nontuberculous pulmonary mycobacteriosis--predisposing factor and environment]

We studied the background of 78 patients with pulmonary nontuberculous mycobacteriosis from 1992 to 1996, and 56 patients (71.8%) were diagnosed as primary infection type and 22 patients (28.2%) as secondary infection type. The former consisted of 17 males and 39 females (mean age +/- SD; 67.4 +/- 12.9 years), and the latter consisted of 13 males and 9 females (mean age +/- SD; 74.0 +/- 7.5 years). Out of all 83 strains, 67 strains (80.7%) were M. avium complex, and out of 36 strains identified either M. avium or M. intracellulare, 34 strains (94.4%) were M. intracellulare and 2 strains (5.6%) were M. avium. Many patients lived in farming areas along the coast, and 35 patients (62.5%) of primary infection type and 11 patients (50%) of secondary infection type were or used to be farmers. Nine patients (16.1%) of primary infection type and 6 patients (27.3%) of secondary infection type had history of gastroduodenal ulcer, while only 3 of all 78 patients had sinusitis. There was a married couple who lived in a same house and 2 sisters who lived apart who were proved to have primary infection type but cross infection was not demonstrated in either case. The development of this disease seems to be related to a genetic susceptibility and environmental factors.

Immunohistochemical studies on phosphorylation of tyrosine hydroxylase in central catecholamine neurons using site- and phosphorylation state-specific antibodies

Antibodies raised to phosphorylated forms of tyrosine hydroxylase, the first and rate-limiting enzyme in the catecholamine biosynthesis, were applied in immunohistochemical studies on rat brain slices incubated in vitro with a phosphodiesterase inhibitor (3-isobutyl-1-methylxanthine, IBMX) and on forskolin on formalin-perfused rat brains. Four antisera/antibodies were used: polyclonal rabbit antisera to (i) tyrosine hydroxylase phosphorylated at serine 40 (THS40p antiserum), (ii) tyrosine hydroxylase phosphorylated at serine 19 (THS19p antiserum), (iii) the native enzyme (pan-tyrosine hydroxylase antiserum), and mouse monoclonal antibody to (iv) native tyrosine hydroxylase. In the in vitro studies THS40p-like immunoreactivity was not observed unless slices were treated with IBMX-forskolin after which a dense fibre network was found in the striatum, and immunoreactive cell bodies were found in the ventral mesencephalon, especially in the ventral tegmental area. Although these cells were pan-tyrosine hydroxylase-positive, several of them were not stained with the tyrosine hydroxylase-monoclonal antibody. Moreover, there was a marked reduction of tyrosine hydroxylase-monoclonal antibody-immunoreactive fibres in drug-treated slices, suggesting that this tyrosine hydroxylase-monoclonal antibody does not recognize the serine 40-phosphorylated form of tyrosine hydroxylase. Treated slices did not show any THS40p-immunoreactive cell bodies in the dopaminergic A11 cell group and only a few, weakly fluorescent neurons were observed in locus coeruleus. However, a sparse fibre plexus was observed in locus coeruleus, possibly reflecting epinephrine fibres. In the perfused brains THS40p-like immunoreactivity could be visualized in some dopamine neurons in the ventral mesencephalon, especially the A10 area, and in noradrenergic locus coeruleus neurons, whereas THS19p-like immunoreactivity was found in all catecholamine groups studied, similar to the results obtained with the pan-tyrosine hydroxylase antiserum and the tyrosine hydroxylase-monoclonal antibody. In forebrain areas known to be innervated by mesencephalic dopamine neurons, no THS40p-positive fibres were observed, whereas THS19p-immunoreactive fibres were found in subregions of the striatum, olfactory tubercle and nucleus accumbens, essentially overlapping with dopamine fibres previously shown to contain cholecystokinin-like immunoreactivity. The present results suggests that antibodies directed against phosphorylated forms of tyrosine hydroxylase can be used to evaluate the state of tyrosine hydroxylase phosphorylation in individual neuronal cell bodies and processes both in vitro and in vivo.

[A case of expanding pulmonary aspergilloma]

A 60-year-old female had old pulmonary tuberculosis. Chest radiographs taken in 1980 revealed a small cavitary lesion due to old lung tuberculosis in the right upper lung fields. Chest radiographs taken in 1984 revealed a fungus ball in the cavity and the adjacent pleura was thickened. Chest radiographs taken in 1994, revealed that the margin of the fungus ball had become ill-defined, and infiltrative shadows surrounded the cavity. A test for aspergillus antigen was positive and toxicolor test was elevated in serum. Chest radiographs taken in 1996 revealed that the fungus ball had enlarged substantially. We consider this case to be a semi-invasive pulmonary aspergillosis which spread by direct invasion from an aspergilloma to the surrounding cavitary wall.

The cholinergic innervation of the adrenal gland and its relation to enkephalin and nitric oxide synthase

Using a monoclonal antibody against rat brain choline acetyltransferase (ChAT) the cholinergic innervation of the adult rat adrenal gland was visualized. Almost all ChAT-positive fibres contained nitric oxide synthase (NOS), whereas enkephalin (ENK) was exclusively found in ChAT fibres among adrenaline chromaffin cells. The ChAT/NOS/ENK fibres disappeared after immunological sympathectomy, indicating a preganglionic origin. ChAT was not found in the superficial peptide- and NOS containing fibre plexus in the adrenal cortex or in small or large intra-adrenal ganglion neurones under control conditions. Even after colchicine treatment only one single ChAT-positive small ganglion neurone was found. It is possible, therefore that some small intra-adrenal ganglion neurones, which express NOS- and VIP-like immunoreactivities, are noncholinergic, nonadrenergic neurones.

Secretory pathways of neuropeptides in rat lumbar dorsal root ganglion neurons and effects of peripheral axotomy

Using immunocytochemistry combined with confocal and electron microscopy, the secretory pathways related to substance P (SP), calcitonin gene-related peptide (CGRP), galanin (GAL), and neuropeptide Y (NPY) were investigated in neurons in rat lumbar (L) 4 and L5 dorsal root ganglia (DRGs) before and after peripheral axotomy. All four peptides were processed through the regulated secretory pathway in many small neurons in normal DRGs, and CGRP through this pathway also in some large neurons. In many small neurons, two neuropeptides could be sorted into the same or separate large dense-core vesicles (LDCVs). The LDCVs had a significantly larger diameter in small as compared to large DRG neurons. Fourteen days after sciatic nerve cut, the levels of SP- and CGRP-like immunoreactivities (-LIs) and the number of LDCVs containing these peptides were markedly reduced, but SP- and CGRP-LIs were still seen in the regulated pathway. GAL-LI was markedly increased in many small neurons and some large neurons and NPY-LI mainly in large neurons. Both peptides were particularly abundant in the Golgi region. In small neurons, the number of LDCVs containing GAL- or NPY-LI was increased, but did not appear to reach the numbers containing SP- or CGRP-LI in normal DRG neurons. After axotomy, CGRP-LI and GAL-LI were often in separate LDCVs. One type of NPY-positive large neurons showed budding off of LDCVs after axotomy, but also some "scattered" labeling in the cytoplasm. In the second type, NPY-LI was mainly found in multivesicular bodies. In several myelinated nerve fibers a "diffuse" distribution of NPY was seen together with some LDCVs containing NPY-LI. In contrast, in unmyelinated nerve fibers, NPY-, GAL-, SP-, and CGRP-LIs were always observed in LDCVs. Thus, both in normal and axotomized DRG neurons, peptides are processed through the regulated pathway. However, in some large neurons, NPY is, in addition, secreted through the constitutive pathway, perhaps as a consequence of limited sorting mechanisms for NPY, i.e., the plasticity of the secretory mechanisms does not match the rate of peptide synthesis after axotomy.

Immunohistochemical demonstration of nitric oxide synthase in the peripheral autonomic nervous system

In the present immunohistochemical study the distribution of nitric oxide synthase (NOS) was studied in various autonomic ganglia and in related peripheral tissues of the rat. For comparison some other neuronal markers including acetylcholinesterase and tyrosine hydroxylase as well as several neuropeptides were analysed on adjacent or the same sections. The distribution of NOS-like immunoreactivity (LI) and of these other markers has been semiquantitatively summarized. In some parasympathetic ganglia such as the sphenopalatine and submandibular ganglia NOS-LI was present in most ganglion cells, at least partly coexisting with peptide histidine isoleucine (PHI), vasoactive intestinal polypeptide (VIP) and neuropeptide tyrosine (NPY). In the pelvic ganglia a comparatively smaller proportion of neurons was NOS-positive and they often contained VIP-LI and less frequently NPY-LI. In the tissues innervated by these ganglia, such as nasal mucosa and salivary glands, NOS-positive fibers were observed around blood vessels and within the glandular parenchyma, although generally less abundant than VIP/PHI nerves, while in the uterus, vas deferens and penis a more close correlation was seen. NOS-positive fibers were also widely distributed in other tissues. In the sympathetic ganglia NOS-LI was mainly present in dense fiber networks, which disappeared after transection of the sympathetic trunc central to the ganglion. Since many cell bodies in the sympathetic lateral column of the spinal cord also were NOS-positive, it is likely that the majority of preganglionic fibers innervating sympathetic ganglia are NOS-positive. VIP-positive cells in stellate ganglia did not contain NOS-LI. The present results suggest that NO may be a messenger molecule both in parasympathetic postganglionic neurons and in preganglionic sympathetic neurons.

Galanin message-associated peptide (GMAP)- and galanin-like immunoreactivities: overlapping and differential distributions in the rat

Using the indirect immunofluorescence method the distribution of galanin message associated peptide (GMAP)- and galanin-like immunoreactivities (LI) was compared in brain, intestine and some endocrine tissues of rat. In general, neurons in the peripheral and central nervous system contained both immunoreactivities. However, in retina the cones were GMAP-positive but galanin-negative. A strong GMAP-LI was observed in the prolactin cells in the anterior lobe of the pituitary and in the insulin cells in the islets of Langerhans in the pancreas, whereas incubation with galanin antiserum resulted in staining of fewer cells (anterior pituitary) or a very weak fluorescence (pancreas). The results show that most neurons express both GMAP- and galanin-LI, but raise the possibility that in some systems there is a tissue specific, posttranslational differential processing of preprogalanin.

Distribution of enkephalin and its relation to serotonin in cat and monkey spinal cord and brain stem

The distribution of enkephalin (ENK)-like immunoreactivity (LI) in spinal cord and medulla oblongata of cat and gray monkey (Macaca fascicularis) was studied by use of immunofluorescence and peroxidase antiperoxidase (PAP) techniques. Possible coexistence between ENK- and 5-hydroxytryptamine (5-HT)-LI was also analyzed with double labeling immunofluorescence. Furthermore, in situ hybridization was used to demonstrate cell bodies in the brain stem expressing mRNA encoding for ENK. ENK-immunoreactive (IR) axonal varicosities and fibers were demonstrated throughout the spinal cord gray matter, with the highest density in the superficial dorsal horn, the area around the central canal, the intermediolateral cell column, the sacral parasympathetic nucleus, and in Onuf's nucleus. In the monkey ventral horn, ENK-IR varicose fibers could in some cases be demonstrated in very close apposition to cell bodies. A low degree of co-localization between ENK- and 5-HT-LI was seen in the spinal cord of both species. Still, fibers containing both compounds could as a rule be demonstrated in every section studied. The highest degree of coexistence was encountered in the motor nucleus of the ventral horn. Six weeks after a low thoracic spinal cord transection a decreased staining for ENK-LI was demonstrated in the ventral horn motor nucleus, whereas other parts of the spinal cord appeared unaffected. In the brain stem of cats after colchicine treatment, ENK-LI was found in a majority of the 5-HT-IR cell bodies in the raphe nuclei (nucleus raphe magnus, pallidus and obscurus) and in the lateral reticular nucleus (rostroventrolateral reticular nucleus). In cat not pretreated with colchicine, a few weakly stained ENK-IR cell bodies could be found in the midline raphe nuclei and in the lateral reticular nucleus with the PAP technique. In the monkey brain stem without colchicine treatment, using the PAP technique, heavily stained ENK-IR cell bodies could be seen in the lateral reticular nucleus whereas, as in the cat, only a few, weakly stained ENK-IR cell bodies could be seen in the midline raphe nuclei. Using in situ hybridization technique, ENK mRNA expressing cells were demonstrated in the lateral reticular nucleus while no convincing mRNA signal could be found over cell bodies in the raphe nuclei. It is concluded that part of the ENKergic innervation of the cord in both species derives from supraspinal or suprasegmental levels.(ABSTRACT TRUNCATED AT 400 WORDS)

Immunohistochemical study of cholecystokinin peptide in rat spinal motoneurons

With the aid of indirect immunofluorescence histochemistry and sequence specific antibodies a possible localization of cholecystokinin (CCK) peptide in spinal motoneurons has been analyzed. To increase peptide levels, the sciatic nerve was ligated, and the area around the ligation was studied 24 hours later. For comparison, antisera raised against calcitonin gene-related peptide (CGRP) and substance P were employed. With CCK specific antisera (directed to the N-terminal portion of CCK-8 or the midportion of CCK-33) accumulation of peptide-like immunoreactivity (LI) was observed in large, dilated axonal swellings proximal to, but at some distance from, the ligature. Such accumulations were also observed with C-terminally directed CCK antiserum, but in addition numerous axons of smaller diameter extending up to the ligation contained this type of immunoreactivity. The latter antiserum is thought to cross-react with CGRP. In fact, this staining pattern was indistinguishable from the one seen after incubation with CGRP antiserum. In contrast substance P-LI could not be seen in the larger dilated axons but only in large numbers of thinner fibers close to the ligation. Double staining experiments revealed that the large dilations contained both CGRP- and CCK-specific LI. Distal to the ligation CGRP- and substance P- but no specific CCK-LI could be observed. The present findings support the view that CCK mRNA in spinal motoneurons is translated into CCK peptide, at least after axotomy, and that the peptide is transported into the motoneuron axon. However, compared to CGRP the CCK levels are presumably low, and the functional role of CCK peptide in motoneurons remains to be established.

Subconjunctival cysticercosis

Two cases of subconjunctival Cysticercus cellulosae have been reported. In one case the cyst presented in the lower fornix, while in the other it was found in the medial canthus. The literature has been reviewed.
