ABSTRACT
Aim To explore the effect of meloxicam on the CUMS-induced depressive-like behaviors in rats and its preliminary mechanism. Methods The rats were exposed to CUMS procedure for 6 weeks to estab-lish the model of depression. Meloxicam(1,3 mg· kg-1 ) and sertraline(5 mg·kg-1 ) were administered to rats from 22d of the stress procedure(once a day,for 21 days,p. o. ) . Depressive-like behaviors were evalu-ated by the open-field test and force swimming test. The levels of PGE2 and TNF-αin cortex were measured by ELISA. Moreover, the concentrations of NE, DA, DOPAC and 5-HIAA were also measured by HPLC, and the protein expression of 5-HT1 AR in cortex was analyzed by the immunohistochemistry. Results Com-pared with the rats of normal control group,the vertical and horizontal movement scores of rats in the open-field test were decreased and the immobility time in the forced swimming test was increased in model group. The levels of PGE2 and TNF-α were both increased signifi-cantly,whereas the concentrations of NE, DA, DOPAC and 5-HIAA were decreased and the expression of 5-HT1AR was reduced in cortex. Compared with the rats of model group, meloxicam significantly improved the depressive behaviors of rats in experimental groups and reversed the content of PGE2 ,TNF-α,NE,DA,DOPAC and 5-HIAA, as well as the expression of 5-HT1AR. Conclusion Meloxicam has a significant protective effect on CUMS-induced depressive-like behaviors, and the protective mechanism might be related to atten-uating inflammation response and reconstructing the balance of the monoamine neurotransmitter system in rat cortex.
ABSTRACT
Objective: To study the effects of Jiaotai Pill on the behavior and monoamine neurotransmitters of chronic mild unpredictable stress (CUMS) depression rat model and to investigate the anti-depression effect and mechanism of Jiaotai Pill. Methods: A total of 72 SD rats were divided into six groups randomly, namely control, model, positive drug (fluoxetine hydrochloride, 7.5 mg/kg), low-, mid-, and high-doses of Jiaotai Pill (crude drug 0.75, 1.5, and 3 g/kg) groups (n = 12), which were reared in cage and execpt the control group, the other five groups of rats were given CUMS to stimulate the production of CUMS depression model, then ig given Jiaotai Pill for 14 d. Rats in each group were measured the body weight and the rate of sucrose preference once a week to observe the open-field activity behavior (through the horizontal grid and the number of vertical changes) at the 5th week. All the animals were killed to get the blood and brain cortex to test the levels of NE, 5-HT, and 5-HIAA in hippocampus, cortex, and hypothalamus by high performance liquid chromatography (HPLC). Results: Compared with the model group, the test indexes of rat body weight, sucrose water consumption, and the open-field activity behavior were significantly increased in the low-, mid-, and high-dose of Jiaotai Pill groups. And the contents of NE and 5-HT increased, while the content of 5-HIAA decreased obviously in the hippocampus, cortex, and hypothalamus in all Jiaotai Pill groups (P < 0.05 or 0.01). Conclusion: Jiaotai Pill has a better antidepressant effect whose mechanism is related to increasing the level of monoamine neurotransmitters in the cerebral cortex.
ABSTRACT
Los tumores carcinoides de testículo son extremadamente raros, representando el 0.23% de los tumores de dicha localización. Se dividen en tres grupos: tumor carcinoide primario de testículo, teratoma de testículo con áreas de carcinoide y tumor carcinoide metastásico de otra localización. Presentamos un paciente de 52 años que consultó por dolor y tumefacción testicular. Se realizó orquiectomía derecha. LDH, alfa feto proteína y beta HCG: normales. Anatomía patológica: tumor blanco amarillento, constituido por células neoplásicas. Inmunohistoquímica: inmunofenotipo correspondiente a tumor neuroendocrino. 5HIAA urinario: normal. Centellografía con (Tc99) octreotide: normal. Se decidió control. Los tumores carcinoides primarios de testículo son infrecuentes, es fundamental descartar localizaciones primarias intestinales para confirmar el diagnóstico. Las herramientas diagnósticas más utilizadas son 5HIAA en orina y centellografía con (TC99) octreotide. El tumor carcinoide primario de testículo presenta un pronóstico favorable luego de la orquiectomía (AU)
Testicular carcinoid tumors are extremely rare. They are divided into three groups: primary testicular carcinoid tumor, testicular teratoma with areas of carcinoid and metastatic carcinoid tumor from another location. We present a 52 years old patient that was admitted with testicular pain and swelling. Right orchiectomy was performed. Serum LDH and alpha, fetoprotein and beta human chorionic gonadotropin were normal. Pathology: white yellowish tumor consisting of neoplastic cells. Immunohistochemistry: immunophenotype corresponding to neuroendocrine tumor. 5HIAA urinary and somatostatin receptor scintigraphy were normal. It was decided to control the patient. Primary testicular carcinoid tumors are uncommon. It is essential to rule out intestinal primary locations to confirm the diagnosis. The diagnostic tools used are 5 HIAA urinary and somatostatin receptor scintigraphy. The primary carcinoid tumor of the testis presents a favorable prognosis after orchiectomy (AU)

Objective To explore the mechanism ofTiaozhong Huatan Anshen Mixture (THAM). Methods A total of 200 healthy Kunming mice were randomly and equally divided into first, second, third and fourth major groups. Each major group was further equally divided into blank group, control group and high, medium, low dose THAM groups. Each group was given an equal volume of NS, estazolam, or high, medium, or low dose THAM by gavage for 7 d. For the first major group, the changes in number of spontaneous activities after administration were evaluated. For the second major group, 60 min after administration, each group was given pentobarbital sodium (30 mg/kg body weight, minimum dose for all mice sleeping) by intraperitoneal injection, and the sleep time was recorded. For the third major group, 60 min after administration, each group was given pentobarbital sodium (15 mg/kg body weight, maximum dose for 90%-100% of all mice having righting reflex) by intraperitoneal injection. The number of mice falling asleep was recorded, and the sleep rate was calculated. For the fourth major group, mice were sacrificed after continuous administration 15 d. They were quickly removed brain tissue;homogenates were taken out in batches;5-HT and 5-HIAA levels in brain tissues were determined according to fluorescence spectrophotometric.Results Compared with the blank group, all treated groups had a reduced number of spontaneous activities, a shortened sleep latency, a prolonged sleep time, and an increased sleep rate after administration (P0.05). Compared with the blank group, brain 5-HT and 5-HIAA levels in all treated groups increased in mice (P<0.01,P<0.05), with the most significant changes seen in the high-dose THAM group (P<0.05).Conclusion THAM has a significant sedative-hypnotic effect. The mechanism may be related to increasing brain 5-HT synthesis and metabolism.

ABSTRACT
Carcinoid syndrome is observed in one third of carcinoid tumors and usually appears when there are liver metastases. One of the main complications of this syndrome is the appearance of tricuspid or pulmonary valvular disease. We report a 56 years old male presenting with malaise and a weight loss of 10 kg. On physical examination, a heart murmur suspicious of a double tricuspid lesion was found. The echocardiogram was suggestive of a carcinoid valvular disease. The abdominal CAT scan showed a small bowel tumor. Urinary 5-hydroxy-indol- acetic acid values were highly elevated. The patient was subjected to excision of the distal ileum, liver metastasectomy and hemicolectomy. The pathological study of the surgical piece confirmed the diagnosis of carcinoid tumor. Two years after surgery, the patient is in stable conditions.

ABSTRACT
BACKGROUND: Nausea and vomiting associated with chemotherapy are common side effects which remain difficult to control. Acute phase nausea and vomiting (0-24 hours after induction of chemotherapy) parallels plasma serotonin release, which explains the effectiveness of 5-HT3 receptor antagonists. Serotonin released from gastrointestinal enterochromaffin cells may mediate chemotherapy-induced emesis. In this study, we analyzed urinary excretion of 5-HIAA, the main metabolite of serotonin. METHODS: Eight men and four women were studied in their cisplatin chemotherapy cycle. Urinary 5-hydroxyindoleacetic aicd (HIAA) levels were determined before and during a 24-hour period under ondansetron prophylaxis. RESULTS: Urinary 5-HIAA excretion for a 24-hour period was increased in all patients after induction of cisplatin (P=0.002). CONCLUSION: Cisplatin chemotherapy is associated with serotonin release in the acute phase. Our finding provides evidence for a relationship between emesis and serotonin following cisplatin chemotherapy.

Various neurotransmitters have been proposed as possible mediators of penile erection. Especially, norepinephrine and serotonin might have a important role in sexual arousal and penile erection. And it could be hypothesized that the psychogenic impotence is associated with the depletion or imbalance of norepinephrine and serotonin from evidences such as the symptomatic manifestation of depression and the antidepressant-induced sexual dysfunction. The authors investigates the association of norepienphrine and serotonin with psychogenic impotence. The psychogenic impotent group(PIG) consisted of twenty-three patients with psychogenic impotence and the controlled group(CG) consisted of twenty-seven patients without psychogenic impotence. PIG had no organic cause accounting for their erectile dysfunction. The Beck Depression Inventory(BDI) and the State-Trait Anxiety Inventory(STAI) were applied to each subject to assess mood, state anxiety(SA) and trait anxiety(TA). Plasma norepinephrine level from systemic blood and 5-hydroxyindoleacetic acid(HIAA) levels from 24-hours urine were measured in each subject. The mean score of BDI of PIG was significantly higher than that of CG(p=0.015). PIG had a tendency of higher TA compared with CG(p=0.054). And also SA was higher in PIG, bud did not show significant difference(p=0.193). The level of norepinephrine was significantly lower in patient with psychogenic impotence(p=0.000). And the level of 24-hours urine 5-HIAA was lower in PIG but did not show significant difference(p=0.494). Although the authors did not exclude depressive disorders in PIG, the present findings suggest that psychogenic impotence might have higher depressive mood and trait anxiety, and be associated with the depletion of norepinephrine in systemic blood.

Este trabalho mostra as vantagens de se determinar simultaneamente os metabólitos VMA, 5HIAA, HVA urinários. A quantificação destes metabólitos são muito importantes nos diagnósticos e tratamento de tumores que se originam na crista neural (VMA, HVA), e diagnóstico da síndrome e tumor carcinóide (5HIAA). A maioria das técnicas utilizadas, limitam-se a medir somente um ou dois setes metabólitos por análise, sendo que a ESA atualmente desenvolveu um procedimento direto, onde se obtém uma quantificação simultânea dos três metabólitos (VMA, 5HIAA, HVA) urinários usando o Sistema Coulochem Electrode Array CEAS

OBJECTIVES: This study was designed to compare risperidone(as an atypical antipsychotic) with haloperidol(as a typical antipsychotic), so we examined the clinical effects and changes of plasma HVA, 5-HIAA & HVA/5-HIAA ratio after 8 week of risperidone or haloperidol trial. METHOD: Twenty-six male chronic schizophrenic patients were treated for 8 weeks with risperidone(N=14) and haloperidol(N=12). The duration of wash-out period was 14 days. The psychopathologic assessment was chechked by Positive and Negative Syndrome Scale(PANSS) and plasma HVA & 5-HIAA was measured by High Performance Liquid Chromatography(HPLC) with electrochemical detector. The checking points were just before drug trial and 1st, 2nd, 4th, and 8th week(total 5 times). RESULTS: 1) Risperidone trial group were more improved than haloperidol tiral group in PANSS scores(total, positive, negative and general psychopathy). 2) Changes of plasma HVA and 5-HIAA in the risperidone and haloperidol trial group were not statistically different. But because baseline 5-HIAA of risperidone trial group was higher than that of haloperidol trial group, the increase of haloperidol trial group would be more. 3) There was significant difference in changes of HVA/5-HIAA ratio between risperidone and haloperidol trial group. But the change of HVA compared with 5-HIAA in risperidone trial group was higher than that of haloperidol trial group. CONCLUSION: These results revealed that risperidone was more effective in clinical symptoms, and suggest that cause of these results may be due to blocking both of dopamine D2 receptors and serotonin 5-HT2 receptors of risperidone.

OBJECTS: This study was purposed to investigate the relationship between urine HVA and 5-HIAA concentrations and clinical symptoms in chronic schizophrenia. METHODS: 272 patients with chronic schizophrenia, diagnosed by DSM-IV criteria, were performed to measure urine HVA and 5-HIAA concentrations and to evaluate the clinical symptoms by using BPRS, PANSS, YBOCS and HAM-D. RESULTS: Urine HVA and 5-HIAA concentrations showed significant correlation with BPRS, positive scale, negative scale and general psychopathology in PANSS and urine HVA/5-HIAA ratios found no significant correlation. Urine HVA concentrations showed significant correlattion with urine 5-HIAA concentrations and urine HVA/5-HIAA ratios had a negative correlation with urine 5-HIAA concentration. As a result of stepwise multiple regression, urine HVA concentrations were significantly correlated with BPRS and positive scale in PANSS and Urine 5-HIAA concentrations were significantly correlated with BPRS. Urine HVA/5-HIAA ratios had significant correlation with HAM-D and BPRS. CONCLUSION: These findings support the hypothesis that the role of central dopamine and serotonin system and the functional interaction of both neurotransmitters are important to clinical symptom formation of chronic schizophrenia.

OBJECTIVES: This study was purposed to examine the changes of plasma homovanillic acid(HVA), 5-hydroxyindoleacetic acid(5-HIAA), and HVA/5-HIAA ratio during an 8-week risperidone trial and to investigate the relationship between the plasma monoamine metabolites and risperidone-induced treatment resposes. METHOD: Eighteen schizophrenic patients were treated for 8 weeks with risperidone. The psychopathology was assessed at baseline just before risperidone trial and then at 1st week, 2nd week, 4th week, and 8th week using the Positive and Negative Syndrome Scale(PANSS) and the Clinical Global Impression scale(CGI). The plasma HVA and 5-HIAA levels were measured using high performance liquid chromatography with electrochemical detection method. RESULTS: 39% of the patients treated with risperidone was categorized as responders, who showed at least a 20% decrease in PANSS total score at the end point of the study. At the end point of the 1st week, there was significant difference in the percent change of plasma HVA between responders(39% increment) and nonresponders(9% increment). But no significant differences in the percent change of plasma 5-HIAA and the percent change of plasma HVA/5-HIAA ratio between responders and nonresponders were observed. CONCLUSION: These results suggest that the magnitude of the early increase of plasma HVA may be associated with risperidone-induced treatment response in schizophrenia.

Twenty newly admitted acute schizophrenic patients were treated with haloperidol for 6 weeks. HVA and 5-HIAA were sampled at baseline, 3days after initial neuroleptic dose, and after 1, 2, 3, 4, 6 weeks of treatment. Nine patients were classified as responders in this prospective haloperidol treatment trial. They had a score of change in the BPRS total scores of 25% or greater. Eleven patients were classified as nonresponders, based on a score of changes in the BPRS total scores of less than 25%. 1) There was no significant difference in plasma HVA/5-HIAA ratio between responder and non-responder before and after haloperidol treatment. 2) There was no significant correlations between plasma HVA/5-HIAA ratio and BPRS total scores. This study could not support the hypothesis that neuroleptic treatment would be effective by changing dopamine and serotonin function and/or by altering their interaction.

This study was done to examine changes of plasma homovanillic, acid(HVA), 5-hydroxyindoleacetic acid(5-HIAA), and HVA/5-HIAA ratio during an 8-week clozapine trial and to investigate the relationship between the plasma monoamine metabolites and treatment responses. Twenty-seven chronic schizophrenic patients were treated for 8 weeks with clozapine. The psychopathology was assessed at baseline just clozapine trial and then every 2 weeks until the end of 8-week clozapine treatment using the positive and Negative Syndrome Scale(PANSS) and the Clinical Global Impression scale(CGI). The plasma HVA and 5-HIAA levels were measured also biweekly using high preformance liquid chromatography with electrochemical detection method. Plasma HVA and 5-HIAA levels were significantly decreased during a 8-week chozapine treatment, although plasma HVA/5-HIAA ratio showed no significant change. The changes of plasma HVA levels were in significant correlations with the changes of PANSS positive scores, of general psychophathology scores, and changes of total scores. The changes of plasma 5-HIAA levels were in significant correlations with the changes of PANSS negative scores. But the changes of plasma HVA/5-HIAA ratio had no significant correlation with any PANSS subscale score changes. 48% of the patients treated with clozapine was categorized as responders, who showed at least a 20% decrease in PANSS total score and a CGI severity score of mildly ill or less(< or =3) of the end pint of the study. The baseline plasma HVA levels and HVA/5-HiAA) ratio were significantly higher in responders(N=13) than in nonresponders(N=14). But no significant difference in the change of plasma HVA between responders(40.3% decrement) and nonresponders(3.1% increment). But no significant difference in the change of plasma 5-HIAA and the change of plasma HVA/5-HIAA ratio between responders and nonresponders were observed. These results suggest that the antipsychotic effect of clozapine on positive symptoms may be associated with dopaminergic blocking activity, and that on negative symptoms may be associated with serotonergic blocking activity. The baseline plasma HVA levels and the change of HVA levels from baseline may be useful predictors of treatment response with clozapine.

Rats were used to establish an animal model of cerebral ischemia and the change of endogenous opiate peptides (LEK, ?-EP, DynA1-13) and monoamines (5-HT, 5-HIAA) levels in the ischemia cerebral tissue were measured. The main findings were as follows: The levels of LEK reduced slightly in cerebral ischemia for 60 minutes, but the levels of DynA1-13 and 5-HIAA increased obviously in cerebral ischemia for 60 minutes. At the same time the levels of ?-EP and 5-HT decreased obviously. The results suggest that the endogenous opiate peptides and monomines play a possible role in the development of cerebral ischemic damage.
ABSTRACT
Analgesia caused by ip baclofen 6. 4 a.nd 12. 8 mg/kg was examined by the hot plate method, showing no accompanied significant changes in 5-HT and 5-HIAA in mouse brains. After loading of L-tfyptophan, the analgesic effect of baclofen was markedly enhanced in both potency and duration, a.nd was related to increases in 5-HT and 5-HIAA in the brain0 Baclofen analgesia was still seen 3d after p-chloro-pheny 1-alanine treatment which rendered 5-HIAA level down to 39% of control. The enhanced functon of 5-HT system in the brain exerted significant synergic effect' on analgesic effect which, however, may be elicited by activating the GABA receptor.
ABSTRACT
Changes of neurotransmitter 5-hydroxytryptamine(5-HT) and its metabolic product 5-hydroxyinaoleacetic acid(5-HIAA) in the spinal cord after comprssion injury in 10 dogs were studied. The spinal cords were compressed for 1 hour with a rubber balloon filled with 0.45ml water when the animals were under pento-barbital anesthesia and dissected after the sacrifice of the animals.The 5-HT and 5-HIAA contents in injured segments, the segments just above and below the injured part, and normal segments of the spinal cord were determined with the fluorometric method. It was found that the 5-HT levels in the segments just above and below the injury were markedly elevated, and the 5-HIAA levels in the injured segments were significantly lowered. It implies that the metabolism of the serotonergic nervous system in the injured segments is inhibited, while that in the segments abvoe or below the injury is enhanced. It is concluded that the serotonergic nervous system of the spinal cord can be involved in the pathophysiology of spinal cord injury.
