Ethnoveterinary knowledge in pastoral Karamoja,Uganda

Ethnopharmacological relevance

The people of Karamoja of northern Uganda chiefly rely on ethnoveterinary knowledge (EVK) to control common livestock health problems. In spite of cattle's central role in Karamojong culture and livelihoods, there has been no systematic recording of their ethnoveterinary plant-based cures to date.

Aim of study

To document the remedies used to treat livestock diseases, their preparation and administration.

Methods

Data were collected using semi-structured interviews, guided questionnaires, group discussions, direct observations and collection trips.

Results

We present information on 209 plant species and 18 non-plant materials. Plant species are distributed over 116 genera and 54 families. The most common medicinal use was treatment against anaplasmosis. Balanites aegyptiacus, Carissa spinarum, Warburgia salutaris and Harrisonia abyssinica had the most uses of all species. All different plant parts were used; bark and underground parts were exploited more frequently than other plant parts. Most remedies listed used a single ingredient, typically soaked in water; only 12.8% remedies used multiple plants. The route of administration was primarily oral followed by topical applications. Almost all plants are collected from the wild; none of the few cultivated plants used had been planted for medicinal purposes.

Conclusions

The pastoralists in the study site possess a wealth of EVK which they use to maintain animal health. Their rich knowledge and high diversity of plants were recorded here for the first time.     

肾综合征出血热内分泌组织中的病毒抗原、病变及其关系

作者应用免疫细胞化学法研究了HFRS尸检内分泌及其有关组织中病毒抗原的分布,病毒抗原阳性细胞与病变的关系,病变的类型及病毒感染对胰腺内胰岛素表达的影响,所用的一抗有抗肾综合征出血热(HFRS)病毒糖蛋白(G_2),核蛋白(NP)及血凝素(HA)抗原的单克隆抗体(15种)和多克隆抗体(PAb)以及抗胰岛素(INS)单克隆抗体。结果显示,内分泌组织中有两种染色形态的病毒抗原,一种是胞浆弥漫染色的抗原,为G_2,NP或HA阳性,阳性细胞弥漫分布,另一种是以病毒包涵体(IB)形式出现的颗粒性抗原,MAbs染色多为实性,PAb染色多为空泡状。在9例胰腺组织中,有4例几乎在所有腺上皮细胞和少数胰岛细胞均为IB阳性,但PAb染色可在胰岛细胞中显示出空泡状IB。在其它内分泌组织中,IB只在少数细胞中出现。抗原阳性细胞很少出现坏死,但在脑垂体及肾上腺灶性或片状凝固性坏死区域也有弥漫性抗原阳性及IB存在。胰腺组织的胰岛素染色显示,除1例胰岛INS强阳性,其余8例均有明显的INS染色减弱及阳性细胞减少的表现。结果提示,内分泌组织中有两种病变,即以IB为特征的病毒直接感染引起的细胞病变,是病毒的弱致病变作用,该病变可能对细胞的内分泌功能产生影响;另一种病变是组织的灶性或大片性同步性凝固性坏死,是继发于病毒感染后的出血和休克,该病变会     

圆形分布在流行病学中的应用——2845例伤寒发病时间分析

应用圆分布分析法对莱芜市22年间两次伤寒流行的发病时间进行了分析。第一次流行在1958年—1968年共发生2239例,按月发病时间计算的平均角度为287.4°(291天),发病高峰在10月18日。第二次流行在1975年—1985年共发生606例,平均角度为294.5°(299天),发病高峰在10月26日。对两个平均角进行显著性检验,F=9.4,P<0.01。即两次流行发病时间的平均角间有高度显著性差异。     

Duration of serum antibody responses following vaccination and revaccination of cattle with non-living commercial Pasteurella haemolytica vaccines

This study was designed to determine the duration of serum antibody responses to Pasteurella haemolytica whole cells (WC) and leukotoxin (LKT) in weanling beef cattle vaccinated with various non-living P. haemolytica vaccines. Serum antibodies to P. haemolytica antigens were determined periodically through day 140 by enzymelinked immunosorbent assays. At day 140, cattle were revaccinated, and antibody responses periodically determined through day 196. Three vaccines were used in two experiments (A and B), OneShot™, Presponse^® HP/tK, and Septimune^® PH-K. In general, all three vaccines between 7 and 14 days induced antibody responses to WC after vaccination. Antibodies to LKT were induced with OneShot and Presponse. Revaccination at days 28 and 140 usually stimulated anamnestic responses. Serum antibodies to the various antigens remained significantly increased for up to 84 days after vaccination or revaccination. The intensity and duration of antibody responses were variable depending on the experiment and vaccines used. Vaccination with OneShot usually stimulated the greatest responses to WC. Vaccination with OneShot or Presponse resulted in equivalent primary anti-LKT responses. In experiment B, spontaneous seroconversion was found in numerous calves on day 112. Revaccination of those cattle at day 140 resulted in markedly variable antibody responses such that several groups had no increase in antibody responses.     

流行性出血热流产婴儿与胎盘的病理变化及巨噬细胞内抗原定位

妊娠6~ 个月孕妇感染流行性出血热(EHF),临床有典型的EHF的发病过程。第23病日血清学检测孕妇外周血EHF-IgG(卅)、IgM(-),第24病日流产一女婴,抽取脐带血检测EHF-IgG(卅),流产女婴心血检测EHF-IgG(卅),IgM(-)。病理:肾小球上皮细胞肿胀,上皮细胞足突融合、坏死,毛细血管基底膜皱缩,肾小管上皮细胞线粒体肥大,间质内大单核细胞浸润。肺间质细胞增生、水肿、毛细血管基底膜不规则增厚,肺泡壁Ⅱ型细胞增多。肝细胞肿胀,胞浆内查见包涵体样物质,有多核肝巨细胞,地依红染色阴性。胎盘母体面、脐带、肺、肝间质内大单核细胞、中性粒细胞浸润。EHF-MCAb荧光直接法染色、PAP、ABC等免疫组化染色,在巨噬细胞浆内均为阳性反应,从而证实母体感染EHF可以经胎盘感染给胎儿,其传播方式可能是通过巨噬细胞系统。     

萘普生对肿瘤性和感染性发热的解热作用

通过双盲法研究表明,萘普生可使肿瘤性发热很快完全消退,对感染性发热很少有解热作用。而扑热息痛对肿瘤性发热和感染性发热的解热作用与萘普生相反。萘普生、扑热息痛可用作肿瘤发热的诊断性治疗。     

Central tumour necrosis factor-α mediates the early gastrointestinal motor disturbances induced by lipopolysaccharide in sheep

Cytokines are involved in fever and other symptoms of the acute phase response induced by endotoxins. The aim of this work was to study the involvement of central tumour necrosis factor-alpha (TNF-alpha) in the changes induced by lipopolysaccharide (LPS) on gastrointestinal (GI) motility in sheep. Body temperature and myoelectric activity of the antrum, duodenum and jejunum was recorded continuously. Intravenous (i.v.) administration of LPS (0.1 micro g kg-1)-induced hyperthermia, decreased gastrointestinal myoelectric activity and increased the frequency of the migrating motor complex (MMC). These effects started 40-50 min after LPS and lasted for 6-7 h. TNF-alpha (50 and 100 ng kg-1) mimicked these effects when injected intracerebroventricularly (i.c.v.) but not i.v. Pretreatment with soluble recombinant TNF receptor (TNFR:Fc, 10 micro g kg-1, i.c.v.) abolished the TNF-induced actions and reduced those evoked by LPS. Furthermore, the effects induced by either LPS or TNF were suppressed by prior i.c.v. injection of indomethacin (100 micro g kg-1). In contrast, the i.v. injections of TNFR:Fc or indomethacin were ineffective. Our data suggest that LPS disturbs GI motility in sheep through a central pathway that involves TNF-alpha and prostaglandins sequentially.
