中医治疗勃起功能障碍相关研究进展

勃起功能障碍又称为阳痿,是临床中常见的一类男性泌尿生殖系统疾病。其临床特征主要为在性活动中无法出现或维持阴茎正常勃起。勃起功能障碍主要由激素缺乏、神经系统紊乱、缺乏足够的阴茎血供或心理问题等引起。目前治疗勃起功能障碍主要为西药磷酸二酯酶抑制剂,该药物可明显改善患者的阴茎充血达到正常勃起。但该药物需要长期服用或每次同房前使用,且具有头痛、颜面潮红等副作用。祖国传统中医药对勃起功能障碍有着深刻认识并积累了丰富的治疗经验。本文基于中医治疗勃起功能障碍角度,对于勃起功能障碍中医发病机制、治疗方法等内容进行了探讨。同时,对中医治疗勃起功能障碍的相关文献进行了复习,为临床治疗勃起功能障碍疾病提供参考依据。     

Expression of the axon growth-related neural adhesion molecule TAG-1/axonin-1 in the adult mouse brain

 TAG-1/axonin-1 is a neuronal cell adhesion molecule of the immunoglobulin superfamily. It is predominantly expressed during neural development and has been reported to be involved in axonal growth and pathfinding. Here, the expression of TAG-1/axonin-1 was investigated anatomically in the adult mouse brain by in situ hybridization using digoxigenin-labeled cRNA probes. Low levels of TAG-1/axonin-1 could be detected in cerebellar granule cells, in tufted and mitral cells of the olfactory bulb, and in pyramidal cells of area CA1 and CA3 of the hippocampus. We suspect that the expression of TAG-1/axonin-1 in these structures of the adult brain may serve neural plasticity. Accepted: 8 September 1997     

The role of body image in sexually avoidant behavior

Spectatoring refers to a cognitive self-absorption, wherein individuals fixate on and carefully monitor personal body parts and/or the adequacy of personal sexual functioning. To examine this process within a university population, undergraduate and graduate students (108 male and 140 female) filled out questionnaires that assessed body image, sexual knowledge, global sexual attitudes (i.e., liberal—conservative), general psychological adjustment, and frequency of sexual behaviors. Multiple regression analyses were used to determine if spectatoring, operationalized by measures of body image, would significantly predict sexually avoidant behavior. Results indicated that body image scores significantly predicted frequency of sexual behaviors for both genders, while general sexual knowledge and psychological adjustment did not predict sexual behavior. Overall, sexual attitude scores were the best predictors of sexual approach/avoidance behaviors for both genders. Implications are drawn for future research using the assessment of more global sex attitudes in the study of spectatoring.     

Sexual dysfunction in male and female patients with epilepsy: A study of 86 outpatients

Sexual dysfunction is a well-known complication of chronic somatic illness. Eighty-six consecutive epileptic outpatients, 38 men and 48 women, without accompanying disorders, were studied. The frequency and symptoms of sexual dysfunction were compared with results from previous studies using identical sexological methodology. The previous studies were of diabetic patients and healthy controls. Eight percent of the epileptic men reported a sexual dysfunction compared to 44% of the diabetics and 13% of the controls. Epileptic women, diabetic women, and controls showed no significant differences in sexual dysfunction (29%, 28%, and 25%, respectively). In both sexes, the sexual function measured by frequencies of coitus and masturbation was normal. Most patients had good control of epileptic attacks on a treatment of monotherapy. Hormonal status was generally within normal limits in both men and women; only a few minor differences were found and they showed no correlation with sexual dysfunction. Psychologically and socially the patients did not differ appreciably from normals, and they exhibited a high degree of disease acceptance. This study, using a biopsychosocial approach in understanding sexual dysfunctions, is in contrast with previous, mainly uncontrolled, studies of epileptic patients that reported high frequencies of hyposexuality in males. We conclude that epilepsy does not necessarily increase the risk of sexual dysfunction in male or female.

Involvement of nitric oxide synthase in the physiology and pathophysiology of facial nerve function and dysfunction

To date few reports have discussed the presence and function of nitric oxide (NO) in structures of the facial nerve. We performed nicotinamide adenine dinucleotide phosphate (NADPH-d)-diaphorase-histochemistry and immunohistochemistry on the intratemporal portion of the facial nerve, including the geniculate ganglion, of guinea pigs using specific antibodies to the three known isoforms of NO synthase and soluble guanylyl-cyclase (sGC). Normal facial nerves were compared to those treated intratympanically with bacterial lipopolysaccharides (LPS) and tumor necrosis factor-α (TNF-α). Both constitutive NOS isoforms and sGC could be detected in the bipolar ganglion cells of normal animals, while the inducible isoform (iNOS or NOS II) was not found. Endothelial NOS (NOS III) and sGC were present in blood vessels and were predominantly found in the perineurial sheath and less in the endoneurium. sGC could be detected in all fibers in a cross section of the facial nerve. LPS and TNF treatment led to the detection of iNOS in the perikaryia of the geniculate ganglion and the perineural sheath. These findings imply that NO may be involved in neurotransmission at least in the visceroafferent system. NO regulates vascular tone of nutrient blood vessels in the perineural sheath and endoneurium. The presence of sGC indicates that NO acts via its second messenger cGMP. NOS II expression may be a contributing factor to facial nerve palsy via two different mechanisms: NOS II-generated NO may lead to an overstimulation of the visceroefferent nerve fibers and motor fibers of the facial nerve. Dysregulation in facial nerve blood vessels could lead to edema and elevated pressure on the nerve within its osseous canal. Received: 13 April 1999 / Accepted: 12 August 1999

Elevated serum PAR-1 levels as an emerging biomarker of inflammation to predict the dengue infection severity

The present study was designed to check the serum levels of protease-activated receptor (PAR-1) in patients during different phases of dengue severity. Moreover, a correlation between serum PAR-1 levels and hematological parameters, inflammatory cytokine levels, and liver functional changes was also determined. Based on the World Health Organization criteria, the study population was divided into: nonsevere dengue fever (DF; n = 30), severe dengue hemorrhagic fever (DHF; n = 19), and severe dengue shock syndrome (DSS; n = 11). The platelet count (PLT) and hematocrit (HCT) were analyzed using an automated hematology analyzer and liver function enzymes aspartate transaminase (AST), alanine transaminase (ALT), and alkaline phosphate (ALP), bilirubin were checked by auto-analyzer using diagnostic kits. Moreover, the levels of inflammatory mediators C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-17 (IL-17), and PAR-1 were determined using respective ELISA kits. The HCT levels were elevated and platelet count decreased significantly during dengue complications (DHF and DSS) compared to the DF patients, while the levels of liver functional biomarkers AST, ALT, ALP, and bilirubin remained elevated in DHF and DSS groups than in the corresponding DF group. Similarly, the inflammatory cytokine levels of CRP, TNF-α, IL-6, and IL-17 in DHF and DSS subjects were markedly increased when observed against DF subjects. Notably, the PAR-1 levels were significantly elevated in DHF and DSS groups than in the DF group and positively correlated with changes in HCT levels, inflammatory biomarkers, and liver enzymes. Our findings conclude that PAR-1 levels persistently increased with the severity of the dengue infection and are strongly associated with various clinical manifestations. Thus, PAR-1 levels can be used as a diagnostic marker for assessing dengue severity.     

The Israeli Sexual Behavior Inventory (ISBI): Scale Construction and Preliminary Validation

This study describes the construction and preliminary validation of the Israeli Sexual Behavior Inventory (ISBI). The ISBI was primarily designed to assess the impact of sexual problems, chronic illness and disability on sexual functioning and experience. Scales were designed to measure three areas of healthy sexual functioning and three areas of sexual dysfunction for both males and females. To provide normative data to which clinical samples can be compared, a large randomly selected sample from an adult male and female population was used for scale construction and preliminary validation. Scale reliabilities, intercorrelations between the ISBI scales, comparisons between the above sample and a clinical sample provide evidence of the ISBI's reliability and validity.
