ABSTRACT
<p><b>Objective</b>To compare the effect of inlaid labial mucosal graft repair (LMGR) with that of bladder mucosal graft repair (BMGR) in the treatment of complex urethral skin fistula after hypospadias repair.</p><p><b>METHODS</b>This study included 55 cases of complex urethral skin fistula following hypospadias repair. We randomly assigned them to receive inlaid LMGR (n=36) or BMGR (n=19). After surgery, we compared the incidence of complications and recurrence rate of urinary fistula between the two groups of patients.</p><p><b>RESULTS</b>The success rates of operation were 91.7% and 84.2% in the LMGR and BMGR groups, respectively, and the penile appearance was desirable in both groups. Postoperative complications included 2 cases of urinary fistula and 1 case of urethral stricture in each group. There were no statistically significant differences between the two groups in the success rate of operation (P>0.05) or the incidence rate of postoperative complications (P>0.05).</p><p><b>CONCLUSIONS</b>Both inlaid LMGR and BMGR yield satisfactory results in the treatment of complex urethral skin fistula. However, LMGR involves less injury in mucosa collection and is easier to perform and therefore deserves more clinical attention.</p>

Phoenix dactylifera belongs to the family Arecaceae. The current aim of our research work is to isolate bio-material from the fruit pulp of Phoenix dactylifera and evaluate its mucoadhesivity. The bio- material was isolated by simple economical process. The isolated biomaterial was subjected for determination of solubility, colour changing point, viscosity, surface tension, pH and chemical tests. The mucoadhesivity of the biomaterial was assessed by shear stress method and rotating cylinder method using Capra aegagrus labium and intestine as mucosal substrates. The results were compared with HPMC and sodium CMC. The research study revealed that the biomaterial from Phoenix dactylifera exhibits promising inbuilt mucoadhesivity. So it can serve as a powerful natural mucoadhesant and may be used to develop mucoadhesive transmucosal drug delivery systems.

ABSTRACT
Adenomatoid hyperplasia of the minor salivary glands is a rare clinicopathologic entity with an unknown etiology. The clinical features of the lesion are nodular, non-painful swellings, and the histologic features are aggregates of normal-appearing, salivary gland tissue, in excess of what would be anticipated for the anatomic site. This tumor is of significance because of its clinical resemblance to salivary gland tumors. Although this lesion may occur at any site on the oral mucosa, the labial mucosa is known to be the least common site. We herein report a rare case of adenomatous hyperplasia of the minor salivary glands located on the lower labial mucosa.

A new menthod for treating old laceration of Lacrimal canaliculus with dacryocystoplasty using conjunctiva or labial mucosa was recommended by the authors. Out of 14 cases,9 cases were operated on with conjunctiva.7 cases were markedly effec- tive,1 cases improved and 1 cases failed.5 cases were operated on with labial mucosa.4 cases were markdly effective and 1 cases improved. The advantages of these two kinds of transplants have been compared.Labial mucosa is better than conjunctiva,and dacryocystoplasty with labial mucosa is more handy and appli- cable.
