    Assessment of Spermatozoa Morphology under Light Microscopy with Different Histologic Stains and Comparison of Morphometric Measurements
    (SOC CHILENA ANATOMIA, 2012) Aksoy, Emine; Aktan, Tahsin Murad; Duman, Selcuk; Cuce, Gokhan
    The aim was to examine the morphology of spermatozoa with different staining methods and aimed to find the better staining methods for morphology of spermatozoa in our study. Randomized 67 patients taken for the study who were admitted to Assisted Reproductive Techniques Unit. In the first part of the study, smears were stained with Hematoxylin Eosin (HE), Toluidin Blue (TB), Giemsa, Wright, ferrous Weigert haematoxylin stain, Orange G, eosin-aniline blue dye, Shorr Method, Papanicolau, Berg Method, Light Green stain, Acridine Orange (AO) and Janus Green dyes. In the second part of the study, smear preparations of 10 patients with normozoospermic were stained with HE, Toluidin Blue (TB), Shorr Method and Papanicolau. Four measurements were made including the middle piece, head length- head width and tail length for 200 spermatozoa with normal morphology. Comparisons were made between the stains that which showed a better morphology. Condensation assessment was not possible in smears stained with Shorr, Berg, Method, AO. Better assessment of condensation could be made in other stains. In the second part the smallest values belonged to of TB stain according to measurements of head of the spermatozoa. There was a significant difference at the head length with TB stain. Although measurements of Shorr and Papanicolau are close to each other and the largest values belonged to Papanicolau dye. It was concluded that measurement values in human sperm morphology could alter with the used staining method.

    Effects of Lipokit (R) Centrifugation on Morphology and Resident Cells of Adipose Tissue
    (SOC CHILENA ANATOMIA, 2013) Duman, Selcuk; Aktan, Tahsin Murad; Cuce, Gokhan; Cihantimur, Bulent; Tokac, Mehmet; Akbulut, Habip
    The aim of adipose tissue engineering is creating autologus vascularized fat tissue to be used for practical soft tissue reconstruction in human clinic. Unfortunately, in practice, long-term results of fat transplantation are often untrustworthy and unreliable, to overcome this problem different many lipoinjection techniques developed in the last 20 years. Centrifuge is a fundamental step in the preparation of adipose tissue. We focused on some cell markers especially MSCs markers and histological structural properties after with lipokit centrifugation and without lipokit centrifugation of adipose tissue obtained by liposuction by this new technique. Adipose tissue was taken by liposuction and separates to two portions. One of them is centrifugated by Lipokit machine (C+) has a micro filter and the other is not (C-). After centrifugation smear slides and paraffin sections were prepared from these tissues. These slides were stained with H&E and Toluidine Blue. Paraffin sections were immunohistochemically stained with CD34, von Willebrand Factor, CD73, CD90 and CD105. Smear preparations showed a continuous three dimensional plasma membrane appearance of adipocytes. C+ and C-showed expression of CD34, von Willebrand Factor, CD73, CD90, CD105. C+ seems to have more free cells expressing than C-. While passing the filter of Lipokit, large adipocytes and connective tissue parts disintegrate and thus increases the surface area of lipoaspirate. Lipokit (R) machine release the group cells which are necessary for angiogenesis and they become more freely to construct angiogenesis.
