Differentiation of Brain Neurosecrotory Cells Depending on Ecdysteroid Content of Haemolymph During 5 Th. Instar Larval Stage of Silkworm, Bombyx Mori
(1999) Parlak, O.; Ünal, G.
In this study, the differentiation in the lateral neurosecretion cells of pars intercerebralis of brain, depending on the different ecdysteroid contents which was determined in the hemolymph of silkworm by radioimmunoassay has been studied using light microscopy. The brains of silkworms in the time of low and high hemolymph ecdysteroid content were fixed in Bouin solution, and the cross sections were stained with PAF after dehidratation. Results shown that the density of fine secretion granulles increased in the cytoplasm of neurosecration cells just before the increase of ecdysteroid content in hemolymph. It was also observed that the ecdysteroid content in hemolynph increased in the following day of excretion.
Gangrenous Meckel's Diverticulum in a Strangulated Umbilical Hernia in a 42-Year Woman: a Case Report
(2010) Sengul, I.; Sengul, D.; Avcu, S.; Parlak, O.
Introduction: Meckel's diverticulum affects 1 - 3 % of general population and is known as the most common anomaly of gastrointestinal tract. However, its estimated lifetime complication rate is approximately 4 %. Intestinal obstruction is most common complication of Meckel's diverticulum in adult population. Case presentation: In the present study, we reported a 42-year-old female patient with a gangrenous Meckel's diverticulum in a strangulated umbilical hernia sac treated by dissection of diverticulomesenteric bands and diverticulectomy. In 36 months follow-up, there was neither any complication nor recurrence of hernia. Conclusion: This case represents a gangrenous Meckel's diverticulum in a strangulated umbilical hernia sac diagnosed in case of emergency. Although it is a very rare phenomenon, we should be vigilant for this entity especially in case of emergency. © 2010 Sengul et al.
