干扰生境下黑叶猴(Trachypithecus francoisi francoisi)日活动时间的分配

1999年至2000年,采用瞬间采样法对贵州省麻阳河国家级自然保护区干扰生境中的野生成年黑叶猴的日活动规律进行了研究。结果表明:干扰生境中野生成年黑叶猴在全年的行为时间分配中表现为休息和摄食所占比例最多,分别为35.41%和31.67%;其次是游走、拥坐和嬉戏,分别为14.44%、9.61%和8.54%;仅将很少时间用于理毛行为,为0.33%。与未干扰生境相比,干扰生境下黑叶猴全年中除用于休息的时间下降外,用于其余活动类型的时间均有所提高。研究还表明野生成年黑叶猴的活动规律在不同季节存在一定差异性。休息和摄食行为在各季节日活动规律中都存在显著高峰期,但高峰期持续时间和强度不同。游走、嬉戏和拥坐行为在各季节的日活动规律所占比例均较低。理毛行为存在季节有或无的现象。

笼养黑叶猴(Trachyp ithecus francoisi)食物量的研究

2002年1～12月在南宁动物园灵长类繁殖中心研究笼养状态下黑叶猴的觅食行为序、雌雄个体对食物的选择和一年四季的日食量.笼养黑叶猴对可采食的植物种类仍存在选择性;觅食行为序由探究行为、抢食行为、爬墙行为和进食行为等4步组成.平均每只黑叶猴个体的日进食量为(1114.96±55.75)g,折合干物质(249.50±16.78)g,具有明显的季节性变化规律,表现出冬季觅食量最多,夏季最少,春季比秋季少的现象.

黑叶猴(Presbytis francoisi)和菲氏叶猴(P.phayrei)的动脉

本文对黑叶猴和菲氏叶猴的动脉作了系统解剖观察,记述了这二种叶猴动脉分支的主要特征。同时还与其他灵长类作了比较和讨论。结果表明,叶猴的动脉除具有猴超科共同特征外,有些特征表明与类人猿相似,比其他猴类更为进化;部分特征似为叶猴所特有。

Variations in diet composition of sympatric Trachypithecus francoisi and Macaca assamensis in the limestone habitats of Nonggang, China

Comparative studies of sympatric species are essential for understanding behavioral and ecological adaptation as well as the mechanisms that can reduce resource competition to allow coexistence. Francois＇ langurs （Trachypithecus francoisi） and Assamese macaques （Macaca assamensis） are sympatric primate species found in the limestone seasonal rainforests of Nonggang Nature Reserve, southwestern Guangxi, China. To explore their different adaptation strategies, we collected data on diet using scan sampling at 15-min intervals. Our results revealed that Francois＇ langurs showed a more flexible diet composition than Assamese macaques Francois＇ langurs increased dietary diversity and mature leaf consumption in response to seasonal scarcity of preferred young leaves and fruits, whereas Assamese macaques relied heavily on young bamboo leaves （Indocalamus calcicolus） in most months These variations reflect the differences in digestive physiology, morphology, and the temporal and spatial distribution of food resources.

Usefulness of a Clinico-Biological Francois’Score in the Diagnosis of Acute Appendicitis:Experience of the University Hospital Center of Parakou,Benin

Introduction: Diagnostic wanderings of acute appendicitis are responsible for serious complications or abusive appendectomies. Existing Clinico-biological scores are efficient. Objective: To determine the diagnostic efficiency of Fran?ois’ score in acute appendicitis. Methodology: over 10 months, all the patients admitted in the CHUD-Parakou Emergency Department for pain in the right iliac fossa had been examined by resident students who calculated Fran?ois’ score. After verification by the surgeon, patients were put into three categories: category 1 score ≥ 2;category 2, score between -6 and 2;category 3, score below -6. Sensitivity and specificity were calculated. Results: out of 54 patients selected (29 men and 25 women), 29 were classified as group 1;19 as group 2 and 6 as group 3. An ultrasound was performed in all patients in group 2, and signs in favor of appendicitis were found in 12 patients. Of the 41 appendicectomies performed, the histologic analysis of 33 operative specimens found a pathological appendix. Sensitivity, specificity and negative predictive value per group were 100%. It has prevented almost in one every four patients (24.07%) an abusive appendectomy. Conclusion: This score would reduce diagnostic wanderings and target patient groups for imaging studies.

1例疑似Francois中央浑浊性角膜营养不良患者施行LASIK手术

Purpose: To report a case of laser in situ keratomileusis (LASIK) surgery performed in a patient with likely central cloudy corneal dystrophy of Francois (CCDF). Design: Observational case report. Methods: A48- year- old woman with likely CCDF had myopic LASIK to establish monovision. Outcome measures included visual acuity, manifest refraction, and slit- lamp examination. Results: At5- year follow- up, the patient had uncorrected visual acuity of 20/100, J1, in the right eye (OD)- and 20/20 in the left eye (OS), consistent with monovision correction. Manifest refraction was- 1.50 OD and- 0.25 OS postoperatively; after retreatment at 1 year for regression, the left eye remained stable over the subsequent4- year period. Slitlamp examination revealed no progression of corneal opacities in either eye. Conclusions: LASIK may be safe and effective in patients with CCDF. Further observations of a greater number of patients are required to confirm these findings.

Francois综合征患者中央云雾状角膜营养不良的活体共焦显微镜检查

Objective: To report in vivo corneal confocal microscopic findings of patients with central cloudy dystrophy of Franc.ois. Methods: Two unrelated patients, a 78- year- old man and a 75- year- old woman, with central cloudy dystrophy of Franc.ois were examined using routine slitlamp biomicroscopy and confocal microscopy. Results: In both cases, slitlamp biomicroscopy showed bilateral polygonal opacities separated by clear spaces. The corneal opacities were most prominent centrally and were located in the deeper stromal layer immediately anterior to the Descemet membrane. By confocal microscopy, normal superficial and basal epithelial layers, midstromal layers, and endothelial layers were noted in both cases. However, small highly refractile granules and deposits were observed in the anterior stromal layer in both cases. Also, multiple dark striae among the extracellular matrix with increased intensities were observed in the posterior stroma adjacent to the corneal endothelial layer in both cases. Conclusions: Abnormal stromal deposits and multiple dark striae were observed in central cloudy dystrophy of Franc.ois using in vivo corneal confocal microscopy. Use, of confocal microscopy to investigate these abnormal stromal opacities may be helpful in differentiating various corneal stromal pathologic features.

中华美学精神跨文化阐释的三种方式

法国学者朱利安、德国学者卜松山、美国学者苏源熙都对中国美学进行了深入研究,其研究方式却各不相同:朱利安基于中西文化的“间距”,着重揭示中华美学的独特性,属于跨越式的跨文化阐释;卜松山则不仅重视中西美学的差异性,也关注其相似性,是沟通式的跨文化阐释;苏源熙对中国美学问题的解答,解构了中西二元论模式,是互动式的跨文化阐释。他们的研究成果,对于中华美学精神的跨文化阐释与对外传播,均具有一定的借鉴意义。

白头叶猴婴猴月龄和性别对母婴关系的影响

非人灵长类动物的母婴关系是婴猴第一次重要的社会体验,对婴猴的生长发育、正常社会行为以及心理健康都具有重要意义。因此,母婴关系研究一直是灵长类学研究的热点之一。为深入了解白头叶猴(Trachypithe⁃cus leucocephalus)母婴关系的发展和影响因素,2009年9月至2010年8月,我们以广西崇左白头叶猴国家级自然保护区岜盆片区的一群野生白头叶猴为研究对象,记录其母婴行为的发生持续时长和发生频次,结合婴猴月龄和性别,探究婴猴月龄和性别对白头叶猴母婴关系的影响。结果表明:婴猴月龄显著影响白头叶猴的母婴关系。随着婴猴月龄的不断增长,母猴对婴猴的保护也随之逐渐减少,表明婴猴的发育是从依赖母猴到逐步独立融入社群的过程。婴猴性别对母婴行为的持续时间无显著影响,但在发生频次上母猴对雌性婴猴的照顾明显多于雄性婴猴。婴猴性别对母婴间的理毛行为、含乳行为均无显著影响,但对怀抱行为具有显著影响。白头叶猴母猴对不同性别的婴猴采取不同的照顾方式,这可能与雄性婴猴和雌性婴猴未来所承担的社会角色不同有关。

黑叶猴个体识别的新方法:基于腹股沟白斑斑纹观测

动物个体识别是进行种群数量监测、动物行为学和生态学研究的基础。通过区分个体特征差异,可收集个体行为、社会联属行为和迁移行为等重要数据(Cronin,2012;Crouse et al.,2017),为动物种群数量评估和制定有效保护策略提供关键基础数据。濒危野生动物个体识别方法目前有足迹识别、条纹识别(顾佳音等,2013)、DNA识别(张保卫,2005)、基于卷积神经网络(Convolutional Neural Network,CNN)进行个体面部图像识别(王革伟,2018;Qi et al.,2020)等。

汉学视域下的“中国像”——以于连、毕来德与沟口雄三为中心

中西思想的异质性始终与中国学者如何介入世界学术的问题相关。就此而言,汉学视域下的“中国”可以提供一种研究的范本。法国汉学家弗朗索瓦·于连将“中国”相对化、特殊化,试图以东-西思想的“间距”实现对西方中心的解构;作为其对立面的瑞士汉学家毕来德则立足普遍性,反对于连过分强调“中国”的异质性。然而,无论采取特殊或普遍的进路,两位汉学家都将中国作为“他者”进行相对化的处理,由此实现对西方思想的重构或补充。与之相对,日本汉学家沟口雄三主张“作为方法的中国”,对于“中国”的定位比上述两位汉学家而言要少了一些话语霸权的意味。并且汉学家视域中的中国往往处于“失语”状态。不同语言之间如何对话,经由外语如何进入中国思想,不仅构成了汉学家们的方法论核心,同时也能为如何通过汉语做哲学带来启发。

Sperm motility inhibitory effect of the benzene chromatographic fraction of the chloroform extract of the seeds of Carica papaya in langur monkey, Presbytis entellus entellus

Aim： To assess the contraceptive efficacy of the benzene chromatographic fraction of the chloroform extract of the seeds of Carica papaya in langur monkeys. Methods： The test substance was given p.o. to five monkeys at 50 mg/kg body weight/day for 360 days. Control animals （n = 3） received olive oil as vehicle. Sperm parameters as per World Health Organization standards, sperm functional tests, morphology of testis and epididymis, haematology, clinical biochemistry, serum testosterone and libido were evaluated. Following completion of 360 days treatment the animals were withdrawn from the treatment and the recovery pattern was assessed by semen analysis and sperm functional tests. Results： Total inhibition of sperm motility was observed following 60 days of treatment that continued until 360 days study period. Sperm count, percent viability and percent normal spermatozoa showed a drastic decline following 30 days of treatment. Sperm morphology showed predominant mid piece abnormalities. Sperm functional tests scored in sterile range. Histology and ultrastructure of testis revealed vacuolization in the Sertoli cells and germ cells. Loss of cytoplasmic organelles was evident in spermatocytes and round spermatids. Histology and ultrastructure of epididymis of treated animals were comparable to those of control animals. Hematological and serum clinical parameters and testosterone levels fluctuated within the control range throughout the study period. Recovery was evident following 60--120 days of treatment withdrawal. Conclusion- The results suggest that the benzene chro- matographic fraction of the chloroform extract of the seeds of Carica papaya shows contraceptive efficacy without adverse toxicity, mediated through inhibition of sperm motility. （Asian JAndro12008 Mar; 10： 298-306）

Comparison of locomotor behaviour between white-headed langurs Trachypithecus leucocephalus and Franois' langurs T. franoisi in Fusui,China

We studied the locomotor behaviour of white-headed langurs Trachypithecus leucocephalus and Franois' langurs T.franoisi to test two hypotheses:(1) these monkeys have evolved locomotor ability to support their activities on limestone hills,and (2) Franois' langurs have evolved more diverse locomotor skills than white-headed langurs. Data were collected from 1996-1998 and in 2005 in Fusui Nature Reserve,Guangxi,and showed that the two species had similar locomotor types,but Franois' langurs had more locomotor modes (26) than white-headed langurs (12). Quadrupedal walking and leaping were two major types,and white-headed langurs were more arboreal than Franois' langurs. We suggest that,while keeping their ancestral locomotor types,the two species have evolved new types allowing them to live on limestone cliffs. Compared to white-headed langurs,Franois' langurs have more diverse locomotor modes that probably have allowed them to live in more habitat types. As an evolutionary outcome,Franois' langurs have a larger distribution

Safety evaluation of long-term vas occlusion with styrene maleic anhydride and its non-invasive reversal on accessory reproductive organs in langurs

Aim:To evaluate the safety of the long term vas occlusion with styrene maleic anhydride (SMA) and its non-invasive reversal at the level of accessory reproductive glands (ARGs) in langurs.Methods:The morphology of seminal vesicle and ventral prostate was evaluated by light as well as transmission electron microscopy.Serum clinical chemistry and urine albumin were evaluated in an autoanalyzer using reagent kits.Fructose,acid phosphatase and zinc in the seminal plasma were evaluated spectrophotometrically according to the WHO manual.Serum testosterone, prostate specific antigen and sperm antibodies were evaluated by enzyme-linked immunosorbent assays (ELISA) using reagent kits and hematology was estimated according to standard procedures.Results:The morphological features and secretory activity of the seminal vesicle and prostate were normal as evidenced by the presence of well- developed mitochondria,rough endoplasmic reticulum,Golgi bodies,secretory granules and normal nuclear charac- teristics throughout the course of investigation.Serum testosterone and prostate specific antigen remained unaltered and serum antisperm antibodies level presented negative titres.Urine albumin was nil.Total red blood corpuscles (RBC),white blood corpuscles (WBC),hemoglobin (Hb) and red cell indices,serum protein,glucose,cholesterol, creatinine,creatine kinase (CK),serum glutamate oxalate transaminase (SGOT),serum glutamate pyruvate transami- nase (SGPT),lactate dehydrogenase (LDH),bilirubin,urea,triglycerides and high-density lipoprotein (HDL) did not show appreciable changes following vas occlusion and after its non-invasive reversal.Although fructose,acid phos- phatase (ACP) and zinc in the seminal plasma showed a significant reduction following vas occlusion,it could not be related to the morphology of seminal vesicle and prostate.Conclusion:SMA vas occlusion and its non-invasive reversal do not damage the accessory reproductive organs.

Attacks on adult females with infants by non-resident males in the Franois langur

Infanticide by males is a common phenomenon in mammals, especially primates, as lactation lasts much longer than gestation in many species. Usually, infanticidal episodes occur soon after group takeovers, and are traditionally considered a male reproductive strategy (i.e., support the sexual selection hypothesis, Hrdy, 1974). To verify the validity of this conception, we observed one group of Franois' langurs in the Nonggang Nature Reserve, China, between August 2003 and July 2004. During the study period, a Franois' langur female with the youngest infant in the group was attacked three times by immigrating males, and later disappeared by the third day after the final attack. We suggest that these attacks on the female-infant dyad represent infanticide attempts by males, and may be the cause of the adult female and her infant's disappearance. Presumably, that female dispersed with her infant to avoid infanticide and was not killed. Though these observations do not completely verify the sexual selection hypothesis, they are not inconsistent with it.
