Prevalence of coronary artery diseases risk factors in Sari-Iran [2005-10]

Coronary artery diseases are one of the main causes of mortality and morbidity. This study was done to determine the prevalence of risk factors for coronary artery diseases in patients referred to angiography center in Sari, Northern Iran. This descriptive study was performed on 2540 patients referred to angiography center in Sari city, northern Iran, during 2005-10. Risk factors including diabetes, hypertension, hyperlipidemia, smoking, Family history, CRP and also ECG changes, type and number of involved artery and the severity of vascular involvement were recorded for each patient. Hypertension, hyperlipidemia, diabetes, smoking were seen in 40.8%, 40.5%, 29.1%, 12.5% of patients, respectively. Positive family history and CRP were found in 10% and 3.4% of the patients, respectively. 23.8% of patients had abnormal ECG. One, two and three vessel diseases were observed in 26.5%, 48.3%, 48.3% of cases, respectively. Left anterior descending artery constriction was seen in 75.8% and 80.4% of males and females, respectively. A significant relationship was found between diabetes and left coronary circumflex [P<0.04] and left anterior descending artery [P<0.03] constriction. Diabetes, hypertension, hyperlipidemia, smoking, family history, abnormal ECG are among the risk factors of coronary artery diseases in this area

Histological and anatomical study of the White Rooster of testis, epididymis and ductus deferens

This study was carried out to investigate the histological and anatomical description of the male genital tract in Iranian Native White Roosters [IWR]. The seminiferous tubules had a dense and compact organization. An average of 12 layers of cells was seen in the seminiferous tubules epithelium. The spermatogonal cell layer showed some variation between different birds in 1 -3 layers; however, the spermatocyte, secondary spermatocytes and spermatids were arranged in 2, 3-4 and 3-5 layers, respectively. The testicles were oval in shape, placed on the left and right sides of midline, situated on the caudal aspect of the lungs and the ventral aspect of either the right or left kidneys, and the visceral surfaces of the left and right lobes of the liver. The epididymis was not divided into recognizable parts and was frontally attached to the corresponding testis on its dorsomedial aspect continuous with the ductus deferens. The ducruli efferentis were moderately large with pseudostratified columnar epithelium lined with three cell types, including ciliated, non-ciliated and basal cells. The connective ducts were covered with scare ciliated pseudostratified columnar epithelium. The epithelium of the epididymis was pseudostratified and columnar, embedded in a loose connective tissue. The proximal part of the ductus deferens was covered with pseudostratified columnar epithelium, which was continuous with simple cuboidal epithelium towards the distal portion. Anatomical studies revealed a large sac-like accessory process that consisted of two non-discrete parts in the fronto ventricular region of the testes between the epididymis and the ductus deferens, which was closely related ventrally to the epididymis and laterally to the kidneys. This organ was lined with stratified cuboidal epithelium with thick clear mucosal muscle. The tunica sub mucosa was evident, and the outer layer was composed of a fibrous capsule with a well-developed vascular supply. This suggested that the role of the sac-like accessory process was as an organ to supply sperm, equivalent to the tail of the epididymis in mammals

Compensatory ovarian changes, mast cell distribution and luminal structure change follwing unilateral ovariectomy in rats

To follow-up the present study, 40 mature female rats were used. The animals were divided into test, control and sham groups. The rats in the test group were laparotomized and unilateral ovariectomy was done. On the 1st and 2nd met-oestrous after operation, the tissue samples were dissected out and processed for histological study. The intact ovary in the test group underwent a significant [P<0.05] hypertrophy and compensatory changes including double angiogenesis, high cytoplasmic vacuolation in granulose cell types of corpus luteum, compensatory follicular development, decreasing of follicular atresia, approximately double ovulation rate and increase in the width of cortex and medulla. The uterine horn on the intact side was approximately similar to the control and sham, while morphometric analyses showed that the horn on the ovariectomized side had significant decrease in the thickness of different layers. Scattering of endometrial glands on the uterine horn of the intact side was normal, showing a dense basophilic appearance in haematoxyline and eosin staining sections. The horn on the ovariectomized side showed low gland scatterin. Histomorphometric analyses showed no significant differences between the vaginas in the three different groups. Distribution of mast cells [MCs] as essential cells participating in angiogenesis was investigated. In the test group, mast cells were considerably increased in number around the blood vessels in the medulla of the intact ovary and intact uterine horn. Mast cells were very low in number on the horn on the ovariectomized side
