Buccoadhesive drug delivery systems have distinct advantages in comparison with oral administration. Plant exudates like gum or mucilage are being studied for their use as pharmaceutical adjuvant. The aim of this study is to evaluate the properties of the Plantago major seed mucilage as a mucoadhesive agent and propranolol hydrochloride is chosen as a model drug. Mucoadhesive tablets of propran...

Drug delivery via buccal mucosa by means of buccoadhesive formulations offer distinct advantages over peroral administration. Recently, plant gums and exudates have been screened for their use as pharmaceutical adjuvants. The aim of this study is to evaluate matrix tablets containing Plantago psyllium seed mucilage in addition to carbopol as a mucoadhesive agent, and propranolol hydrochloride a...

To the Editor: Categorization of pleural effusions as transudates or exudates assists diagnostic and therapeutics decisions. To meet the criteria of Light et al. (1 ) for exudates, an effusion must have at least one of the following: a ratio of pleural fluid (PF) protein to serum protein .0.5, a ratio of PF to serum lactic dehydrogenase (LD) .0.6, and PF LD more than two-thirds the upper limit ...

Five known sesquiterpenoids, solavetivone, lubimin, lubiminoic acid, aethione and lubiminol were isolated from the root exudates recovered from Solanum aethiopicum by a newly proposed method using charcoal. Quantitative analysis of the sesquiterpenoids in the root exudates of S. aethiopicum and S. melongena suggested that relatively large amounts of the sesquiterpenoids were exuded from the roo...

The exploitation of petroleum, the production and use petroleum products causes pollution that is harmful to ecology environment. At present, hydrocarbon has become a universal concern in world. As one bioremediation methods, plant root exudate repair effect eliminating toxic substances To explore role exudates glycine phytoremediation petroleum-contaminated soil, seed germination pot experimen...

Retinal exudates are a characteristic feature of many retinal diseases such as Diabetic Retinopathy. We address the development of a method to quantitatively diagnose these random yellow patches in colour retinal images automatically. After a colour normalisation and contrast enhancement preprocessing step, the colour retinal image is segmented using Fuzzy C-Means clustering. We then classify t...

Rocha e Silva and Rosenthal (1) have reported that the exudates from burnt rat skin contain histamine, bradykinin, adenosine derivatives and possibly serotonin and other as yet unidentified pharmacologically active and toxic substances. Hodson (2) has reported the peripheral antiserotonin activity of B.W. 501 C 67 (α-anilino-N-2-m-chlorophenoxypropyl acetamidine hydrochloride monohydrate)...

Exudates in retinal images are one of the early signs of the vision-threatening diabetic retinopathy and diabetic macular edema. Early diagnosis is very helpful in preventing the progression of the disease. In this work, we propose a fully automatic exudate segmentation method based on the state-of-the-art residual learning framework. With our proposed end-to-end architecture the training is do...

Exudates are the primary sign of Diabetic Retinopathy. Early detection can potentially reduce the risk of blindness. An automatic method to detect exudates from low-contrast digital images of retinopathy patients with non-dilated pupils using a Fuzzy C-Means (FCM) clustering is proposed. Contrast enhancement preprocessing is applied before four features, namely intensity, standard deviation on ...
