The Impact

Acellular nerve allografts (ANGs) represent a promising alternative in nerve repair. Our aim is to improve the structural and biomechanical properties of biocompatible Sondell (SD) and Roosens (RS) based ANGs using genipin (GP) as a crosslinker agent ex vivo. The impact of two concentrations of GP (0.10% and 0.25%) on Wistar rat sciatic nerve-derived ANGs was assessed at the histological, biomechanical, and biocompatibility levels. Histology confirmed the differences between SD and RS procedures, but not remarkable changes were induced by GP, which helped to preserve the nerve histological pattern. Tensile test revealed that GP enhanced the biomechanical properties of SD and RS ANGs, being the crosslinked RS ANGs more comparable to the native nerves used as control. The evaluation of the ANGs biocompatibility conducted with adipose-derived mesenchymal stem cells cultured within the ANGs confirmed a high degree of biocompatibility in all ANGs, especially in RS and RS-GP 0.10% ANGs. Finally, this study demonstrates that the use of GP could be an efficient alternative to improve the biomechanical properties of ANGs with a slight impact on the biocompatibility and histological pattern. For these reasons, we hypothesize that our novel crosslinked ANGs could be a suitable alternative for future in vivo preclinical studies.

Thymic Tumors

Spontaneous thymic lesions were investigated in Wistar (Cpb:WU) rats. Thymic tumors were not uncommon and most showed medullary differentiation. Thymic involution was investigated in a limited group of animals in which the survival rate for males and females was similar. The histological pattern of thymic involution differed between sexes. Severe thymic involution occurred more frequently in males than in females and at an earlier age.

Histological Characteristics

Background: Histological characteristics of endometrial biopsy material as assessed by light microscopy remain the diagnostic standard for the clinical diagnosis of endometrial pathology. Management of abnormal uterine bleeding is not complete without tissue diagnosis. The aim of the study was to find out the histopathological pattern of the endometrium in abnormal uterine bleeding. Materials and Methods: Endometrial biopsy specimens received from Jan 2007 to Nov 2010 were studied retrospectively in the Department of Histopathology, Helping Hands Community Hospital, Kathmandu. The specimens were routinely processed and the hematoxyllin and eosin stained slides were studied. Results: A total of 300 specimens were analyzed. In the group of patients less than 40 years of age, 73 (50%) were normal, 34(23%) had abnormal physiologic changes and 13 (9%) had pregnancy related complications and benign changes. In the age group between 40 – 55 years, abnormal physiological changes, benign conditions and normal physiological changes were 45 (32%), 41 (29%) and 37 (26%) respectively. In the age group > 55 years, there were 3(21%) malignant and 3(21%) benign conditions. There were 5(36%) unsatisfactory samples in this age group. Conclusion: It is important to know the histological pattern of the endometrium in abnormal uterine bleeding in different age groups since it will help in the management of the cases. In this study endometrial hyperplasias were seen in 55 cases (18.8%). The importance of studying the histological pattern of endometrium in abnormal uterine bleeding in different age group is to help in correctly managing the cases.
