Checking the quality of meat products is very important. The purpose of this research is to investigatethe presence of unauthorized tissues in this product to improve its quality and safety level and promote the health of society. In this cross-sectional descriptive study, sausages with meat percentages of 40, 55 and 70 wererandomly purchased from three factories (10 pieces each) and divided into three pieces and then three slides from each piece with hematoxylin-eosin method was prepared (270 slides in total). Finally, 10 microscopic fields were examined from each slide. The data were analyzed by using SPSS software. At the level of less than 0.05, the difference between the groups was considered significant and the results were shown as Mean ± SD. Furthermore, the frequency percentage of tissues in each of the sausages was calculated. Cartilage tissue, bone, skin, kidney, salivary gland, blood vessel, abdominal viscera and plant tissues were observed in all meat products. However, central nervous system and spleen tissues were not seen in any of the samples. In sausage 40%, the highest frequency percentage of tissue was related to skin, in sausage 55%, skin and kidney, and in sausage 70%, kidney. In addition, the amount of illegal tissues was different in 40%, 55% and 70% sausages and this difference was significant in many tissues. By using histological methods, it is possible to detect illegal tissues in meat products and obligate factories to comply with the national standard.

 Ovarian torsion (adnexal torsion) is a rare event in pediatric patients which is primarily managed by pediatric general surgeons.

 This study presents a case of ovarian torsion in a 2-yr-old girl with a history of episodic lower abdominal pain, nausea, and vomiting for 2 days. Her physical examination was normal except for mild tenderness in the lower abdomen with no palpable mass. A color Doppler ultrasound was performed for further investigation, and an ovarian torsion was reported without sonographic signs of intussusception and acute appendicitis, so she underwent laparotomy. A relatively complete torsion was observed in the left ovarian pedicle. Initially, the left ovary and fallopian tube had a dark appearance, and 10-15% of the ovarian tissue was still normal. Detorsion of ovary was done and it was decided to preserve the ovary. After about 20 min, the color of ovary and fallopian tube returned to relatively normal, indicating normal blood flow. The patient was discharged 2 days later because a follow-up color Doppler ultrasound showed normal ovarian blood flow.

 The possibility of ovarian torsion must be considered in all female infants with suspicious abdominal pain.

In the present study the effect of Salvia rhytidia extract on thickness of cerebral cortex and hippocampal regions following ischemia-reperfusion (IR) injuries is evaluated.
In the present study the extract of S. rhytidia, an endemic plant from south eastern of Iran, was used to prevent IR injuries induced in cerebral cortex and hippocampus of rats.
In this cross-sectional study, 35 male healthy Wistar rats between 250 - 350 g were randomly divided into 7 groups of 5 rats. Control group (A), ischemic groups (B, D, E, F, G) that left common carotid and left vertebral arteries were occluded for 10 minutes. Group D received S. rhytidia extract (3.2 mg/kg) and group E received silymarin (50 mg/kg), a chemical drug which is used for reducing oxidative stress, 2 hours after ischemia, whereas group F received S. rhytidia extract (3.2 mg/kg) and group G received silymarin (50 mg/kg), 72, 48, 24 and 0 hours before ischemia. Group B received no drug and sham group (C) received normal saline (NS) without ischemia. After 24 hours reperfusion, the brains of rats were prepared for histological studies and the data were analyzed using one way ANOVA and Duncan as posthoc test.
IR resulted in decrease in thickness of the cerebral cortex, CA1 and CA2 regions of the hippocampus in groups B, D and E compared to control (P This study showed that S. rhytidia extract can protect the forebrain from IR injuries due to antioxidative effect of the drug.

In order to study the normal hematopoiesis, cellular components and myeloid/erythroid (M/E) ratio in the bone marrow of the pheasant (Phasianus colchicus), bone marrow samples were collected from the proximal tibiotarsus bone of 16 clinically healthy adult pheasant. The bone marrow smears were stained using the Giemsa stain. The results indicated that the development and formation of blood cells in the bone marrow of pheasant were similar to other birds, whereas the morphology of the cells was similar to chickens, ducks, quail, and black-head gull. The mean M/E ratio was 1.24, the mean erythroid percentage was 42.24, the mean myeloid percentage was 52.62, and the mean percentage of all other cells percentage was 5.38. There was no significant difference in any of the cellular composition between male and female.
