Decellularized porcine conjunctiva as an alternative substrate for tissue-engineered epithelialized conjunctiva

Xenogeneic Acellular Conjunctiva Matrix as a Scaffold of Tissue-Engineered Corneal Epithelium

Amniotic membrane-based tissue-engineered corneal epithelium has been widely used in the reconstruction of the ocular surface. However, it often degrades too early to ensure the success of the transplanted corneal epithelium when treating patients with severe ocular surface disorders. In the present study, we investigated the preparation of xenogeneic acellular conjunctiva matrix (aCM) and eval...

Decellularized tissue-engineered blood vessel as an arterial conduit.

Arterial tissue-engineering techniques that have been reported previously typically involve long waiting times of several months while cells from the recipient are cultured to create the engineered vessel. In this study, we developed a different approach to arterial tissue engineering that can substantially reduce the waiting time for a graft. Tissue-engineered vessels (TEVs) were grown from ba...

Decellularized Cartilage as a Scaffold for Tissue Engineered Cartilage

Bleeding from the conjunctiva.

The discovery of frank bleeding from the conjunctiva, apart from injury, is a relatively rare condition, but it is not infrequent to find a sanguinous discharge in cases of severe inflammation of the conjunctiva. The various causes of bleeding from the conjunctiva are vicarious menstruation, haemophilia, anaemia, jaundice, vascular tumours, bleeding from the lacrimal gland, regurgitation of blo...

Amyloidosis of the conjunctiva.

Case Reports Case 1.-A male farmer, aged 36 years, presented with thickening of the right upper eyelid, which was everted with difficulty to reveal a pea-sized nodule in the lateral part of the tarsal conjunctiva, which was irregularly thickened up to the fornices. Clinical signs of accompanying trachoma were present in both eyes. The nodule was excised and sent for microscopic examination. The...
