The aim of this paper is to illustrate a method for identifying macroscopic anatomical differences among the brains of different populations of subjects. The method involves spatially normalizing the structural MR images of a number of subjects so that they all conform to the same stereotactic space. Multivariate statistics are then applied to the parameters describing the estimated nonlinear deformations that ensue. To illustrate the method, we compared the gross morphometry of male and female subjects. We also assessed brain asymmetry, the effect of handedness, and interactions among these effects.

Turkish Journal of Medical Sciences
It is known that periods of constant darkness and constant light cause stim-ulation and inhibition of melatonin secretion from the pineal gland. It is also suggested that neuroendocrine responses to environmental stimuli, such as light, can influence immune responses through the pineal gland. For these reasons, in this study the effects of the alterations in the photoperiod rhythm on the pineal gland and thymus morphology were experimentally investigated. 30 Swiss albino rats, aged 4 wk, were divided into 3 groups. Group I rats were kept in a dark room, group II in a room under a bright artificial light and …

Turkish Journal of Medical Sciences
Cryptorchidism causes a failure in testosterone secretion from the testicles. The metabolism of the adrenocortical steroids is influenced by sex hormones. Therefore testicular failure may cause structural and func-tional alterations in adrenal cortex. It is the aim of the present study to evaluate the effect of experimental caryptorchidism on the ultrastructure of the rat adrenal cortex, especialy on the reticularis region during prepubertal and postpubertal ages. Three groups of animals were used in the present study. The first (prepubertal) group consisted of 5,21-day old rats whereas the second (postpubertal) group was made of 5,3-month old rats.

Identification Of Fibronectin Adhesins On Candidaalbicans, Gülhan Vardar-Ünlü
Turkish Journal of Medical Sciences
The pattern of distribution of fibronectin adhesins on yeast and hyphal-form Candida albicanswas studied with gold-labelled fibronectin and transmission electron microscopy. The germ-tube parts of the hyphal-form cells were the major binding sites for gold-labelled fibronectin, and the attached yeast-cell parts and yeast-form cell remained unlabelled. Therefore, the walls of the germ tube parts of hyphal-form cells might be sites of important interactions between C. albicans and host tissues containing fibronectin.

Turkish Journal of Medical Sciences
The importance of bone marrow biopsy in Hudgkin's Disase is well known. The incidence of bone marrow involvement in Hudgkin's Disase varies from 2% to 29%. The presence of myelofibrosis is not sufficent evidence for a definitive diagnosis of bone marrow involment. Patients having myelofibrosis as a first symptom without pripherallympadenopathy must be distinguished from patients with idiopathic myelofibrosis. In this study, we examined the frequency of bone marrow involvement and the degree of myelofibrosis in Hudgkin's Disase. We found the incidence of bone marrow involvement to be 5.6%, and that of myelofibrosis to be 31.6%. The high incidence of …
