Abstract When lupin plants were grown in phosphorus-deficient nutrient solutions, the activity of acid phosphatase secreted from their roots remarkably increased comparison with that under adequate phosphorus conditions. Based on staining IEF gels, many isozymes present and leaves, but one these was mainly into rhizosphere. This main purified solution where grown, using ion exchange chromatography DEAE-Sepharose CL-6B, gel filtration Bio-Gel P-200, preparative-PAGE. The molecular weight...

Abstract This retrospective observational study aims to report the clinical characteristics and surgical results in eyes with Posner-Schlossman syndrome (PSS), compare these outcomes between cytomegalovirus (CMV)-positive -negative eyes. We reviewed medical records of 21 consecutive immunocompetent patients clinically diagnosed PSS years 2010 2018. Aqueous humor was collected from all affected detect if CMV present, polymerase chain reaction (PCR) performed using herpesvirus family primers....

Purpose . To present our findings in a case of delayed-onset postoperative endophthalmitis caused by Brachybacterium paraconglomeratum , rare organism. Observations A 57-year-old man presented with epiphora and photophobia 17 weeks after routine cataract extraction phacoemulsification intraocular lens implantation. Because was suspected to be low-grade pathogen or fungus, an anterior chamber tap performed. However, both multiplex PCR culturing were negative. The patient treated topical...

Flexor-plasty of the elbow has been performed using either a tubed complete latissimus dorsi muscle or musculocutaneous transposition in eight patients, six whom had brachial plexus palsy and two traumatic loss anterior musculature overlying soft tissue. The range follow-up was from one to years. When postoperative results were evaluated according criteria Segal (1959), excellent four cases good three, with failure. indications, operative technique are discussed.

52 known stock strains of yeast-like fungi were tested for thiaminase activity and the following results obtained.1. Of 51 tested, 16 (30per cent) decomposed more than 50per cent, 9 (18per 30-50per while 27 (52per less 30per cent thiamine added at pH 6.5 45° in 2 hours presence 3γ thiamine.2. The representative strains, Trichosporon cutaneum 0174, Torula lactis 0398, Torulopsis xylinus 0454, Cryptococcus albidus 0378 C4 strain Yonezawa Aoki was studied found that optimum 6.0 temperature 40°....

In order to search for Pb-free relaxor substances and define behaviour, a theoretical aspect is presented from not only microscopic but also phenomenological viewpoint. order–disorder type mixed crystals, the approach attempted under conditions similar those perovskite-type oxides. Basing on theory precursor glass state, two kinds of technique X-ray diffuse scattering (static properties) quadrupole perturbed nuclear magnetic resonance (NMR-NQR) (dynamic are discussed in ferroelectric (FE) --...

Abstract Background The nasal to temporal amplitudes ratio (N/T) of multifocal electroretinography (mfERG) scans measured within 5° the macula can be used detect glaucomatous change. photopic negative response (PhNR) mfERG elicited by a circular stimulus centered on fovea was significantly reduced in eyes with glaucoma. PhNR B-wave (PhNR/B) is optimal measure PhNR. However, clinical superiority for evaluating glaucoma patients has not been determined between N/T and PhNR/B yet. Methods For...

We describe a 62-year-old man who developed subacute visual loss after cord blood stem cell transplantation for malignant lymphoma. Brain magnetic resonance imaging (MRI) showed bilateral hyperintense lesions in the occipital and parietal lobes. A diagnosis of progressive multifocal encephalopathy (PML) was established following brain biopsy detection JC virus (JCV) deoxyribonucleic acid (DNA) cerebrospinal fluid (CSF). He optic ataxia inattention, then diagnosed as having Bálint syndrome....

1995~2001年に所沢肛門病院で経験した大腸癌症例の検討を行った.7年間に38,212例の大腸内視鏡検査が施行され,762例の大腸癌(進行癌498例,早期癌264例)が発見された.これは検査総数の約2.0%に達していた.進行癌では,男性の直腸癌が有意に多かった(p<0.01).平均年齢は進行癌(62.4歳)が早期癌(59.8歳)に比べ2.6歳高かった(p<0.002).当院の第一紹介病院である防衛医大第1外科で1995~99年に施行された大腸癌初回手術例743例を,当院から紹介した257例とその他の施設から紹介された476例に分け,両群の特徴を比較検討した.当院から紹介した症例では,主訴が出血である症例の割合が高く,腫瘍占拠部位では有意に直腸癌が多かった(p<0.0001).平均年齢は当院で有意に若年であるものの(p=0.02),臨床病期は有意に高く(p=0.01),痔疾患のある患者は出血しても痔からの出血と考え放置している可能性が示唆され注意が必要と考えられた.
