Idiopathic hypertrophic pachymeningitis in six dogs: MRI, CSF and histological findings, treatment and outcome

Idiopathic hypertrophic pachymeningitis has been described in humans as a rare, chronic progressive non-specific inflammatory and fibrotic disease of the dura mater. This is a case series of six canine cases of presumptive or confirmed intracranial idiopathic hypertrophic pachymeningitis. These dogs were included in this retrospective study, based on magnetic resonance imaging findings. All presented with pachymeningeal thickening and enhancement without involvement of the leptomeninges on magnetic resonance imaging and no underlying cause identified on cerebrospinal fluid analysis, complete blood count, serum biochemistry and infectious disease titres. Histopathological examination was available in one case. Response to immunomodulatory treatment (corticosteroids and cytosine arabinoside) was achieved in five cases. Idiopathic hypertrophic pachymeningitis should be considered as a possible differential diagnosis for dogs with pachymeningeal thickening on magnetic resonance imaging and no identified underlying cause. The prognosis appears to be fair to poor.     

Do bacteria-sized marine eukaryotes consume significant bacterial production?

Up to 60 percent of the total marine primary production (or about one-fourth of the total global carbon dioxide fixation) passes through the free-living bacterioplankton. Grazing by bacteriovores is probably the predominant fate of the bacteria, although data are scarce. Evidence is presented that previously uncharacterized, small eukaryotes that are able to pass even 0.6-micrometer filters may be responsible for a large fraction (more than 50 percent) of the total grazing in coastal waters. These organisms have not yet been observed microscopically.     

福建引种浙江油桐试验初报

一、前言 福建是我国油桐南缘产区。本课题组油桐引种试验自1979年开始,数年来先后自川、浙、皖、桂、黔、云、鄂、湘、苏、豫、赣等十一个省区引进三年桐、千年桐的各地方品种类型计74个,在我省闽侯县桐口林场建立了油桐试验基地,总面积180亩,其中包括三年桐实生品种园及无性系品种园,共引进省内外品种家系21个、无性系18个。     

冬春放牧及补饲精料促使肉牛生长的试验

试验采用随机区组组合排列方法分为５个处理组，每处理重复了３次，共１５个试验小区，每小区放养婆罗门杂交断阉牛４头，试验期１２６天，每隔２１天称重１次。结果表明：除仅在自然草地放牧，不补饲的阉牛在全试验期减重４ｋｇ外，其他４组试验牛分别增重１９，１５，６５和５２ｋｇ，与第一处理组相比，差异显著（Ｐ＜０．０５）。
